Other 48-- attributes include sets of meanings for overloaded names, possible 49-- types for overloaded expressions, flags to indicate deferred constants, 50-- incomplete types, etc. These attributes are stored in available fields in 51-- tree nodes (i.e. fields not used by the parser, as defined by the Sinfo 52-- package specification), and accessed by means of a set of subprograms 53-- which define an abstract interface. 54 55-- There are two kinds of semantic information 56 57-- First, the tree nodes with the following Nkind values: 58 59-- N_Defining_Identifier 60-- N_Defining_Character_Literal 61-- N_Defining_Operator_Symbol 62 63-- are called Entities, and constitute the information that would often 64-- be stored separately in a symbol table. These nodes are all extended 65-- to provide extra space, and contain fields which depend on the entity 66-- kind, as defined by the contents of the Ekind field. The use of the 67-- Ekind field, and the associated fields in the entity, are defined 68-- in this package, as are the access functions to these fields. 69 70-- Second, in some cases semantic information is stored directly in other 71-- kinds of nodes, e.g. the Etype field, used to indicate the type of an 72-- expression. The access functions to these fields are defined in the 73-- Sinfo package, but their full documentation is to be found in 74-- the Einfo package specification. 75 76-- Declaration processing places information in the nodes of their defining 77-- identifiers. Name resolution places in all other occurrences of an 78-- identifier a pointer to the corresponding defining occurrence. 79 80-------------------------------- 81-- The XEINFO Utility Program -- 82-------------------------------- 83 84-- XEINFO is a utility program which automatically produces a C header file, 85-- einfo.h from the spec and body of package Einfo. It reads the input files 86-- einfo.ads and einfo.adb and produces the output file einfo.h. XEINFO is run 87-- automatically by the build scripts when you do a full bootstrap. 88 89-- In order for this utility program to operate correctly, the form of the 90-- einfo.ads and einfo.adb files must meet certain requirements and be laid 91-- out in a specific manner. 92 93-- The general form of einfo.ads is as follows: 94 95-- type declaration for type Entity_Kind 96-- subtype declarations declaring subranges of Entity_Kind 97-- subtype declarations declaring synonyms for some standard types 98-- function specs for attributes 99-- procedure specs 100-- pragma Inline declarations 101 102-- This order must be observed. There are no restrictions on the procedures, 103-- since the C header file only includes functions (The back end is not 104-- allowed to modify the generated tree). However, functions are required to 105-- have headers that fit on a single line. 106 107-- XEINFO reads and processes the function specs and the pragma Inlines. For 108-- functions that are declared as inlined, XEINFO reads the corresponding body 109-- from einfo.adb, and processes it into C code. This results in some strict 110-- restrictions on which functions can be inlined: 111 112-- The function spec must be on a single line 113 114-- There can only be a single statement, contained on a single line, 115-- not counting any pragma Assert statements. 116 117-- This single statement must either be a function call with simple, 118-- single token arguments, or it must be a membership test of the form 119-- a in b, where a and b are single tokens. 120 121-- For functions that are not inlined, there is no restriction on the body, 122-- and XEINFO generates a direct reference in the C header file which allows 123-- the C code in the backend to directly call the corresponding Ada body. 124 125---------------------------------- 126-- Handling of Type'Size Values -- 127---------------------------------- 128 129-- The Ada 95 RM contains some rather peculiar (to us) rules on the value 130-- of type'Size (see RM 13.3(55)). We have found that attempting to use 131-- these RM Size values generally, and in particular for determining the 132-- default size of objects, creates chaos, and major incompatibilities in 133-- existing code. 134 135-- We proceed as follows, for discrete and fixed-point subtypes, we have 136-- two separate sizes for each subtype: 137 138-- The Object_Size, which is used for determining the default size of 139-- objects and components. This size value can be referred to using the 140-- Object_Size attribute. The phrase "is used" here means that it is 141-- the basis of the determination of the size. The backend is free to 142-- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone 143-- character might be stored in 32 bits on a machine with no efficient 144-- byte access instructions such as the Alpha. 145 146-- The default rules for the value of Object_Size for fixed-point and 147-- discrete types are as follows: 148 149-- The Object_Size for base subtypes reflect the natural hardware 150-- size in bits (see Ttypes and Cstand for integer types). For 151-- enumeration and fixed-point base subtypes have 8, 16, 32, or 64 152-- bits for this size, depending on the range of values to be stored. 153 154-- The Object_Size of a subtype is the same as the Object_Size of 155-- the subtype from which it is obtained. 156 157-- The Object_Size of a derived base type is copied from the parent 158-- base type, and the Object_Size of a derived first subtype is copied 159-- from the parent first subtype. 160 161-- The Value_Size which is the number of bits required to store a value 162-- of the type. This size can be referred to using the Value_Size 163-- attribute. This value is used to determine how tightly to pack 164-- records or arrays with components of this type, and also affects 165-- the semantics of unchecked conversion (unchecked conversions where 166-- the Value_Size values differ generate a warning, and are potentially 167-- target dependent). 168 169-- The default rules for the value of Value_Size are as follows: 170 171-- The Value_Size for a base subtype is the minimum number of bits 172-- required to store all values of the type (including the sign bit 173-- only if negative values are possible). 174 175-- If a subtype statically matches the first subtype, then it has 176-- by default the same Value_Size as the first subtype. This is a 177-- consequence of RM 13.1(14) ("if two subtypes statically match, 178-- then their subtype-specific aspects are the same".) 179 180-- All other subtypes have a Value_Size corresponding to the minimum 181-- number of bits required to store all values of the subtype. For 182-- dynamic bounds, it is assumed that the value can range down or up 183-- to the corresponding bound of the ancestor. 184 185-- The RM defined attribute Size corresponds to the Value_Size attribute. 186 187-- The Size attribute may be defined for a first-named subtype. This sets 188-- the Value_Size of the first-named subtype to the given value, and the 189-- Object_Size of this first-named subtype to the given value padded up 190-- to an appropriate boundary. It is a consequence of the default rules 191-- above that this Object_Size will apply to all further subtypes. On the 192-- other hand, Value_Size is affected only for the first subtype, any 193-- dynamic subtypes obtained from it directly, and any statically matching 194-- subtypes. The Value_Size of any other static subtypes is not affected. 195 196-- Value_Size and Object_Size may be explicitly set for any subtype using 197-- an attribute definition clause. Note that the use of these attributes 198-- can cause the RM 13.1(14) rule to be violated. If two access types 199-- reference aliased objects whose subtypes have differing Object_Size 200-- values as a result of explicit attribute definition clauses, then it 201-- is erroneous to convert from one access subtype to the other. 202 203-- At the implementation level, Esize stores the Object_Size and the 204-- RM_Size field stores the Value_Size (and hence the value of the 205-- Size attribute, which, as noted above, is equivalent to Value_Size). 206 207-- To get a feel for the difference, consider the following examples (note 208-- that in each case the base is short_short_integer with a size of 8): 209 210-- Object_Size Value_Size 211 212-- type x1 is range 0..5; 8 3 213 214-- type x2 is range 0..5; 215-- for x2'size use 12; 16 12 216 217-- subtype x3 is x2 range 0 .. 3; 16 2 218 219-- subtype x4 is x2'base range 0 .. 10; 8 4 220 221-- dynamic : x2'Base range -64 .. +63; 222 223-- subtype x5 is x2 range 0 .. dynamic; 16 3* 224 225-- subtype x6 is x2'base range 0 .. dynamic; 8 7* 226 227-- Note: the entries marked * are not actually specified by the Ada 95 RM, 228-- but it seems in the spirit of the RM rules to allocate the minimum number 229-- of bits known to be large enough to hold the given range of values. 230 231-- So far, so good, but GNAT has to obey the RM rules, so the question is 232-- under what conditions must the RM Size be used. The following is a list 233-- of the occasions on which the RM Size must be used: 234 235-- Component size for packed arrays or records 236-- Value of the attribute Size for a type 237-- Warning about sizes not matching for unchecked conversion 238 239-- The RM_Size field keeps track of the RM Size as needed in these 240-- three situations. 241 242-- For elementary types other than discrete and fixed-point types, the 243-- Object_Size and Value_Size are the same (and equivalent to the RM 244-- attribute Size). Only Size may be specified for such types. 245 246-- For composite types, Object_Size and Value_Size are computed from their 247-- respective value for the type of each element as well as the layout. 248 249-- All size attributes are stored as Uint values. Negative values are used to 250-- reference GCC expressions for the case of non-static sizes, as explained 251-- in Repinfo. 252 253-------------------------------------- 254-- Delayed Freezing and Elaboration -- 255-------------------------------------- 256 257-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 258-- freeze node, which appears later in the expanded tree. 259 260-- a) The flag is used by the front-end to trigger expansion actions which 261-- include the generation of that freeze node. Typically this happens at the 262-- end of the current compilation unit, or before the first subprogram body is 263-- encountered in the current unit. See files freeze and exp_ch13 for details 264-- on the actions triggered by a freeze node, which include the construction 265-- of initialization procedures and dispatch tables. 266 267-- b) The presence of a freeze node on an entity is used by the backend to 268-- defer elaboration of the entity until its freeze node is seen. In the 269-- absence of an explicit freeze node, an entity is frozen (and elaborated) 270-- at the point of declaration. 271 272-- For object declarations, the flag is set when an address clause for the 273-- object is encountered. Legality checks on the address expression only take 274-- place at the freeze point of the object. 275 276-- Most types have an explicit freeze node, because they cannot be elaborated 277-- until all representation and operational items that apply to them have been 278-- analyzed. Private types and incomplete types have the flag set as well, as 279-- do task and protected types. 280 281-- Implicit base types created for type derivations, as well as classwide 282-- types created for all tagged types, have the flag set. 283 284-- If a subprogram has an access parameter whose designated type is incomplete 285-- the subprogram has the flag set. 286 287----------------------- 288-- Entity Attributes -- 289----------------------- 290 291-- This section contains a complete list of the attributes that are defined 292-- on entities. Some attributes apply to all entities, others only to certain 293-- kinds of entities. In the latter case the attribute should only be set or 294-- accessed if the Ekind field indicates an appropriate entity. 295 296-- There are two kinds of attributes that apply to entities, stored and 297-- synthesized. Stored attributes correspond to a field or flag in the entity 298-- itself. Such attributes are identified in the table below by giving the 299-- field or flag in the attribute that is used to hold the attribute value. 300-- Synthesized attributes are not stored directly, but are rather computed as 301-- needed from other attributes, or from information in the tree. These are 302-- marked "synthesized" in the table below. The stored attributes have both 303-- access functions and set procedures to set the corresponding values, while 304-- synthesized attributes have only access functions. 305 306-- Note: in the case of Node, Uint, or Elist fields, there are cases where the 307-- same physical field is used for different purposes in different entities, 308-- so these access functions should only be referenced for the class of 309-- entities in which they are defined as being present. Flags are not 310-- overlapped in this way, but nevertheless as a matter of style and 311-- abstraction (which may or may not be checked by assertions in the 312-- body), this restriction should be observed for flag fields as well. 313 314-- Note: certain of the attributes on types apply only to base types, and 315-- are so noted by the notation [base type only]. These are cases where the 316-- attribute of any subtype is the same as the attribute of the base type. 317-- The attribute can be referenced on a subtype (and automatically retrieves 318-- the value from the base type). However, it is an error to try to set the 319-- attribute on other than the base type, and if assertions are enabled, 320-- an attempt to set the attribute on a subtype will raise an assert error. 321 322-- Other attributes are noted as applying to the [implementation base type 323-- only]. These are representation attributes which must always apply to a 324-- full non-private type, and where the attributes are always on the full 325-- type. The attribute can be referenced on a subtype (and automatically 326-- retrieves the value from the implementation base type). However, it is an 327-- error to try to set the attribute on other than the implementation base 328-- type, and if assertions are enabled, an attempt to set the attribute on a 329-- subtype will raise an assert error. 330 331-- Abstract_States (Elist25) 332-- Defined for E_Package entities. Contains a list of all the abstract 333-- states declared by the related package. 334 335-- Accept_Address (Elist21) 336-- Defined in entries. If an accept has a statement sequence, then an 337-- address variable is created, which is used to hold the address of the 338-- parameters, as passed by the runtime. Accept_Address holds an element 339-- list which represents a stack of entities for these address variables. 340-- The current entry is the top of the stack, which is the last element 341-- on the list. A stack is required to handle the case of nested select 342-- statements referencing the same entry. 343 344-- Access_Disp_Table (Elist16) [implementation base type only] 345-- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged 346-- types to point to their dispatch tables. The first two entities are 347-- associated with the primary dispatch table: 1) primary dispatch table 348-- with user-defined primitives 2) primary dispatch table with predefined 349-- primitives. For each interface type covered by the tagged type we also 350-- have: 3) secondary dispatch table with thunks of primitives covering 351-- user-defined interface primitives, 4) secondary dispatch table with 352-- thunks of predefined primitives, 5) secondary dispatch table with user 353-- defined primitives, and 6) secondary dispatch table with predefined 354-- primitives. The last entity of this list is an access type declaration 355-- used to expand dispatching calls through the primary dispatch table. 356-- For an untagged record, contains No_Elist. 357 358-- Access_Disp_Table_Elab_Flag (Node30) [implementation base type only] 359-- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged 360-- types whose dispatch table elaboration must be completed at run time 361-- by the IP routine to point to its pending elaboration flag entity. 362-- This flag is needed when the elaboration of the dispatch table relies 363-- on attribute 'Position applied to an object of the type; it is used by 364-- the IP routine to avoid performing this elaboration twice. 365 366-- Activation_Record_Component (Node31) 367-- Defined for E_Variable, E_Constant, E_Loop_Parameter, and formal 368-- parameter entities. Used in Opt.Unnest_Subprogram_Mode, in which case 369-- a reference to an uplevel entity produces a corresponding component 370-- in the generated ARECnT activation record (Exp_Unst for details). 371 372-- Actual_Subtype (Node17) 373-- Defined in variables, constants, and formal parameters. This is the 374-- subtype imposed by the value of the object, as opposed to its nominal 375-- subtype, which is imposed by the declaration. The actual subtype 376-- differs from the nominal one when the latter is indefinite (as in the 377-- case of an unconstrained formal parameter, or a variable declared 378-- with an unconstrained type and an initial value). The nominal subtype 379-- is the Etype entry for the entity. The Actual_Subtype field is set 380-- only if the actual subtype differs from the nominal subtype. If the 381-- actual and nominal subtypes are the same, then the Actual_Subtype 382-- field is Empty, and Etype indicates both types. 383-- 384-- For objects, the Actual_Subtype is set only if this is a discriminated 385-- type. For arrays, the bounds of the expression are obtained and the 386-- Etype of the object is directly the constrained subtype. This is 387-- rather irregular, and the semantic checks that depend on the nominal 388-- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv). 389 390-- Address_Clause (synthesized) 391-- Applies to entries, objects and subprograms. Set if an address clause 392-- is present which references the object or subprogram and points to 393-- the N_Attribute_Definition_Clause node. Empty if no Address clause. 394-- The expression in the address clause is always a constant that is 395-- defined before the entity to which the address clause applies. 396-- Note: The backend references this field in E_Task_Type entities??? 397 398-- Address_Taken (Flag104) 399-- Defined in all entities. Set if the Address or Unrestricted_Access 400-- attribute is applied directly to the entity, i.e. the entity is the 401-- entity of the prefix of the attribute reference. Also set if the 402-- entity is the second argument of an Asm_Input or Asm_Output attribute, 403-- as the construct may entail taking its address. And also set if the 404-- entity is a subprogram and the Access or Unchecked_Access attribute is 405-- applied. Used by the backend to make sure that the address can be 406-- meaningfully taken, and also in the case of subprograms to control 407-- output of certain warnings. 408 409-- Aft_Value (synthesized) 410-- Applies to fixed and decimal types. Computes a universal integer that 411-- holds value of the Aft attribute for the type. 412 413-- Alias (Node18) 414-- Defined in overloadable entities (literals, subprograms, entries) and 415-- subprograms that cover a primitive operation of an abstract interface 416-- (that is, subprograms with the Interface_Alias attribute). In case of 417-- overloaded entities it points to the parent subprogram of a derived 418-- subprogram. In case of abstract interface subprograms it points to the 419-- subprogram that covers the abstract interface primitive. Also used for 420-- a subprogram renaming, where it points to the renamed subprogram. For 421-- an inherited operation (of a type extension) that is overridden in a 422-- private part, the Alias is the overriding operation. In this fashion a 423-- call from outside the package ends up executing the new body even if 424-- non-dispatching, and a call from inside calls the overriding operation 425-- because it hides the implicit one. Alias is always empty for entries. 426 427-- Alignment (Uint14) 428-- Defined in entities for types and also in constants, variables 429-- (including exceptions where it refers to the static data allocated for 430-- an exception), loop parameters, and formal parameters. This indicates 431-- the desired alignment for a type, or the actual alignment for an 432-- object. A value of zero (Uint_0) indicates that the alignment has not 433-- been set yet. The alignment can be set by an explicit alignment 434-- clause, or set by the front-end in package Layout, or set by the 435-- back-end as part of the back-end back-annotation process. The 436-- alignment field is also defined in E_Exception entities, but there it 437-- is used only by the back-end for back annotation. 438 439-- Alignment_Clause (synthesized) 440-- Applies to all entities for types and objects. If an alignment 441-- attribute definition clause is present for the entity, then this 442-- function returns the N_Attribute_Definition clause that specifies the 443-- alignment. If no alignment clause applies to the type, then the call 444-- to this function returns Empty. Note that the call can return a 445-- non-Empty value even if Has_Alignment_Clause is not set (happens with 446-- subtype and derived type declarations). Note also that a record 447-- definition clause with an (obsolescent) mod clause is converted 448-- into an attribute definition clause for this purpose. 449 450-- Anonymous_Designated_Type (Node35) 451-- Defined in variables which represent anonymous finalization masters. 452-- Contains the designated type which is being serviced by the master. 453 454-- Anonymous_Masters (Elist29) 455-- Defined in packages, subprograms, and subprogram bodies. Contains a 456-- list of anonymous finalization masters declared within the related 457-- unit. The list acts as a mapping between a master and a designated 458-- type. 459 460-- Anonymous_Object (Node30) 461-- Present in protected and task type entities. Contains the entity of 462-- the anonymous object created for a single protected or task type. 463 464-- Associated_Entity (Node37) 465-- Defined in all entities. This field is similar to Associated_Node, but 466-- applied to entities. The attribute links an entity from the generic 467-- template with its corresponding entity in the analyzed generic copy. 468-- The global references mechanism relies on the Associated_Entity to 469-- infer the context. 470 471-- Associated_Formal_Package (Node12) 472-- Defined in packages that are the actuals of formal_packages. Points 473-- to the entity in the declaration for the formal package. 474 475-- Associated_Node_For_Itype (Node8) 476-- Defined in all type and subtype entities. Set non-Empty only for 477-- Itypes. Set to point to the associated node for the Itype, i.e. 478-- the node whose elaboration generated the Itype. This is used for 479-- copying trees, to determine whether or not to copy an Itype, and 480-- also for accessibility checks on anonymous access types. This 481-- node is typically an object declaration, component declaration, 482-- type or subtype declaration. 483 484-- For an access discriminant in a type declaration, the associated_ 485-- node_for_itype is the corresponding discriminant specification. 486 487-- For an access parameter it is the enclosing subprogram declaration. 488 489-- For an access_to_protected_subprogram parameter it is the declaration 490-- of the corresponding formal parameter. 491-- 492-- Itypes have no explicit declaration, and therefore are not attached to 493-- the tree: their Parent field is always empty. The Associated_Node_For_ 494-- Itype is the only way to determine the construct that leads to the 495-- creation of a given itype entity. 496 497-- Associated_Storage_Pool (Node22) [root type only] 498-- Defined in simple and general access type entities. References the 499-- storage pool to be used for the corresponding collection. A value of 500-- Empty means that the default pool is to be used. This is defined 501-- only in the root type, since derived types must have the same pool 502-- as the parent type. 503 504-- Barrier_Function (Node12) 505-- Defined in protected entries and entry families. This is the 506-- subprogram declaration for the body of the function that returns 507-- the value of the entry barrier. 508 509-- Base_Type (synthesized) 510-- Applies to all type and subtype entities. Returns the base type of a 511-- type or subtype. The base type of a type is the type itself. The base 512-- type of a subtype is the type that it constrains (which is always 513-- a type entity, not some other subtype). Note that in the case of a 514-- subtype of a private type, it is possible for the base type attribute 515-- to return a private type, even if the subtype to which it applies is 516-- non-private. See also Implementation_Base_Type. Note: it is allowed to 517-- apply Base_Type to other than a type, in which case it simply returns 518-- the entity unchanged. 519 520-- Block_Node (Node11) 521-- Defined in block entities. Points to the identifier in the 522-- Block_Statement itself. Used when retrieving the block construct 523-- for finalization purposes, The block entity has an implicit label 524-- declaration in the enclosing declarative part, and has otherwise 525-- no direct connection in the tree with the block statement. The 526-- link is to the identifier (which is an occurrence of the entity) 527-- and not to the block_statement itself, because the statement may 528-- be rewritten, e.g. in the process of removing dead code. 529 530-- Body_Entity (Node19) 531-- Defined in package and generic package entities, points to the 532-- corresponding package body entity if one is present. 533 534-- Body_Needed_For_SAL (Flag40) 535-- Defined in package and subprogram entities that are compilation 536-- units. Indicates that the source for the body must be included 537-- when the unit is part of a standalone library. 538 539-- Body_Needed_For_Inlining (Flag299) 540-- Defined in package entities that are compilation units. Used to 541-- determine whether the body unit needs to be compiled when the 542-- package declaration appears in the list of units to inline. A body 543-- is needed for inline processing if the unit declaration contains 544-- functions that carry pragma Inline or Inline_Always, or if it 545-- contains a generic unit that requires a body. 546-- 547-- Body_References (Elist16) 548-- Defined in abstract state entities. Contains an element list of 549-- references (identifiers) that appear in a package body whose spec 550-- defines the related state. If the body refines the said state, all 551-- references on this list are illegal due to the visible refinement. 552 553-- BIP_Initialization_Call (Node29) 554-- Defined in constants and variables whose corresponding declaration 555-- is wrapped in a transient block and the inital value is provided by 556-- a build-in-place function call. Contains the relocated build-in-place 557-- call after the expansion has decoupled the call from the object. This 558-- attribute is used by the finalization machinery to insert cleanup code 559-- for all additional transient objects found in the transient block. 560 561-- C_Pass_By_Copy (Flag125) [implementation base type only] 562-- Defined in record types. Set if a pragma Convention for the record 563-- type specifies convention C_Pass_By_Copy. This convention name is 564-- treated as identical in all respects to convention C, except that 565-- if it is specified for a record type, then the C_Pass_By_Copy flag 566-- is set, and if a foreign convention subprogram has a formal of the 567-- corresponding type, then the parameter passing mechanism will be 568-- set to By_Copy (unless specifically overridden by an Import or 569-- Export pragma). 570 571-- Can_Never_Be_Null (Flag38) 572-- This flag is defined in all entities. It is set in an object which can 573-- never have a null value. Set for constant access values initialized to 574-- a non-null value. This is also set for all access parameters in Ada 83 575-- and Ada 95 modes, and for access parameters that explicitly exclude 576-- exclude null in Ada 2005 mode. 577-- 578-- This is used to avoid unnecessary resetting of the Is_Known_Non_Null 579-- flag for such entities. In Ada 2005 mode, this is also used when 580-- determining subtype conformance of subprogram profiles to ensure 581-- that two formals have the same null-exclusion status. 582-- 583-- This is also set on some access types, e.g. the Etype of the anonymous 584-- access type of a controlling formal. 585 586-- Can_Use_Internal_Rep (Flag229) [base type only] 587-- Defined in Access_Subprogram_Kind nodes. This flag is set by the 588-- front end and used by the backend. False means that the backend 589-- must represent the type in the same way as Convention-C types (and 590-- other foreign-convention types). On many targets, this means that 591-- the backend will use dynamically generated trampolines for nested 592-- subprograms. True means that the backend can represent the type in 593-- some internal way. On the aforementioned targets, this means that the 594-- backend will not use dynamically generated trampolines. This flag 595-- must be False if Has_Foreign_Convention is True; otherwise, the front 596-- end is free to set the policy. 597-- 598-- Setting this False in all cases corresponds to the traditional back 599-- end strategy, where all access-to-subprogram types are represented the 600-- same way, independent of the Convention. For further details, see also 601-- Always_Compatible_Rep in Targparm. 602-- 603-- Efficiency note: On targets that use dynamically generated 604-- trampolines, False generally favors efficiency of top-level 605-- subprograms, whereas True generally favors efficiency of nested 606-- ones. On other targets, this flag has little or no effect on 607-- efficiency. The front end should take this into account. In 608-- particular, pragma Favor_Top_Level gives a hint that the flag 609-- should be False. 610-- 611-- Note: We considered using Convention-C for this purpose, but we need 612-- this separate flag, because Convention-C implies that in the case of 613-- P'[Unrestricted_]Access, P also have convention C. Sometimes we want 614-- to have Can_Use_Internal_Rep False for an access type, but allow P to 615-- have convention Ada. 616 617-- Chars (Name1) 618-- Defined in all entities. This field contains an entry into the names 619-- table that has the character string of the identifier, character 620-- literal or operator symbol. See Namet for further details. Note that 621-- throughout the processing of the front end, this name is the simple 622-- unqualified name. However, just before the backend is called, a call 623-- is made to Qualify_All_Entity_Names. This causes entity names to be 624-- qualified using the encoding described in exp_dbug.ads, and from that 625-- point (including post backend steps, e.g. cross-reference generation), 626-- the entities will contain the encoded qualified names. 627 628-- Checks_May_Be_Suppressed (Flag31) 629-- Defined in all entities. Set if a pragma Suppress or Unsuppress 630-- mentions the entity specifically in the second argument. If this 631-- flag is set the Global_Entity_Suppress and Local_Entity_Suppress 632-- tables must be consulted to determine if there actually is an active 633-- Suppress or Unsuppress pragma that applies to the entity. 634 635-- Class_Wide_Clone (Node38) 636-- Defined on subprogram entities. Set if the subprogram has a class-wide 637-- ore- or postcondition, and the expression contains calls to other 638-- primitive funtions of the type. Used to implement properly the 639-- semantics of inherited operations whose class-wide condition may 640-- be different from that of the ancestor (See AI012-0195). 641 642-- Class_Wide_Type (Node9) 643-- Defined in all type entities. For a tagged type or subtype, returns 644-- the corresponding implicitly declared class-wide type. For a 645-- class-wide type, returns itself. Set to Empty for untagged types. 646 647-- Cloned_Subtype (Node16) 648-- Defined in E_Record_Subtype and E_Class_Wide_Subtype entities. 649-- Each such entity can either have a Discriminant_Constraint, in 650-- which case it represents a distinct type from the base type (and 651-- will have a list of components and discriminants in the list headed by 652-- First_Entity) or else no such constraint, in which case it will be a 653-- copy of the base type. 654-- 655-- o Each element of the list in First_Entity is copied from the base 656-- type; in that case, this field is Empty. 657-- 658-- o The list in First_Entity is shared with the base type; in that 659-- case, this field points to that entity. 660-- 661-- A record or classwide subtype may also be a copy of some other 662-- subtype and share the entities in the First_Entity with that subtype. 663-- In that case, this field points to that subtype. 664-- 665-- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides 666-- this field. Note that this field ONLY appears in subtype entries, not 667-- in type entries, it is not defined, and it is an error to reference 668-- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity. 669 670-- Comes_From_Source 671-- This flag appears on all nodes, including entities, and indicates 672-- that the node was created by the scanner or parser from the original 673-- source. Thus for entities, it indicates that the entity is defined 674-- in the original source program. 675 676-- Component_Alignment (special field) [base type only] 677-- Defined in array and record entities. Contains a value of type 678-- Component_Alignment_Kind indicating the alignment of components. 679-- Set to Calign_Default normally, but can be overridden by use of 680-- the Component_Alignment pragma. Note: this field is currently 681-- stored in a non-standard way, see body for details. 682 683-- Component_Bit_Offset (Uint11) 684-- Defined in record components (E_Component, E_Discriminant). First 685-- bit position of given component, computed from the first bit and 686-- position values given in the component clause. A value of No_Uint 687-- means that the value is not yet known. The value can be set by the 688-- appearance of an explicit component clause in a record representation 689-- clause, or it can be set by the front-end in package Layout, or it can 690-- be set by the backend. By the time backend processing is completed, 691-- this field is always set. A negative value is used to represent 692-- a value which is not known at compile time, and must be computed 693-- at run-time (this happens if fields of a record have variable 694-- lengths). See package Layout for details of these values. 695-- 696-- Note: Component_Bit_Offset is redundant with respect to the fields 697-- Normalized_First_Bit and Normalized_Position, and could in principle 698-- be eliminated, but it is convenient in several situations, including 699-- use in the backend, to have this redundant field. 700 701-- Component_Clause (Node13) 702-- Defined in record components and discriminants. If a record 703-- representation clause is present for the corresponding record type a 704-- that specifies a position for the component, then the Component_Clause 705-- field of the E_Component entity points to the N_Component_Clause node. 706-- Set to Empty if no record representation clause was present, or if 707-- there was no specification for this component. 708 709-- Component_Size (Uint22) [implementation base type only] 710-- Defined in array types. It contains the component size value for 711-- the array. A value of No_Uint means that the value is not yet set. 712-- The value can be set by the use of a component size clause, or 713-- by the front end in package Layout, or by the backend. A negative 714-- value is used to represent a value which is not known at compile 715-- time, and must be computed at run-time (this happens if the type 716-- of the component has a variable length size). See package Layout 717-- for details of these values. 718 719-- Component_Type (Node20) [implementation base type only] 720-- Defined in array types and string types. References component type. 721 722-- Contains_Ignored_Ghost_Code (Flag279) 723-- Defined in blocks, packages and their bodies, subprograms and their 724-- bodies. Set if the entity contains any ignored Ghost code in the form 725-- of declaration, procedure call, assignment statement or pragma. 726 727-- Contract (Node34) 728-- Defined in constant, entry, entry family, operator, [generic] package, 729-- package body, protected type, [generic] subprogram, subprogram body, 730-- variable and task type entities. Points to the contract of the entity, 731-- holding various assertion items and data classifiers. 732 733-- Contract_Wrapper (Node25) 734-- Defined in entry and entry family entities. Set only when the entry 735-- [family] has contract cases, preconditions, and/or postconditions. 736-- Contains the entity of a wrapper procedure which encapsulates the 737-- original entry and implements precondition/postcondition semantics. 738 739-- Corresponding_Concurrent_Type (Node18) 740-- Defined in record types that are constructed by the expander to 741-- represent task and protected types (Is_Concurrent_Record_Type flag 742-- set). Points to the entity for the corresponding task type or the 743-- protected type. 744 745-- Corresponding_Discriminant (Node19) 746-- Defined in discriminants of a derived type, when the discriminant is 747-- used to constrain a discriminant of the parent type. Points to the 748-- corresponding discriminant in the parent type. Otherwise it is Empty. 749 750-- Corresponding_Equality (Node30) 751-- Defined in function entities for implicit inequality operators. 752-- Denotes the explicit or derived equality operation that creates 753-- the implicit inequality. Note that this field is not present in 754-- other function entities, only in implicit inequality routines, 755-- where Comes_From_Source is always False. 756 757-- Corresponding_Function (Node32) 758-- Defined on procedures internally built with an extra out parameter 759-- to return a constrained array type, when Modify_Tree_For_C is set. 760-- Denotes the function that returns the constrained array type for 761-- which this procedure was built. 762 763-- Corresponding_Procedure (Node32) 764-- Defined on functions that return a constrained array type, when 765-- Modify_Tree_For_C is set. Denotes the internally built procedure 766-- with an extra out parameter created for it. 767 768-- Corresponding_Protected_Entry (Node18) 769-- Defined in subprogram bodies. Set for subprogram bodies that implement 770-- a protected type entry to point to the entity for the entry. 771 772-- Corresponding_Record_Component (Node21) 773-- Defined in components of a derived untagged record type, including 774-- discriminants. For a regular component or a girder discriminant, 775-- points to the corresponding component in the parent type. Set to 776-- Empty for a non-girder discriminant. It is used by the back end to 777-- ensure the layout of the derived type matches that of the parent 778-- type when there is no representation clause on the derived type. 779 780-- Corresponding_Record_Type (Node18) 781-- Defined in protected and task types and subtypes. References the 782-- entity for the corresponding record type constructed by the expander 783-- (see Exp_Ch9). This type is used to represent values of the task type. 784 785-- Corresponding_Remote_Type (Node22) 786-- Defined in record types that describe the fat pointer structure for 787-- Remote_Access_To_Subprogram types. References the original access 788-- to subprogram type. 789 790-- CR_Discriminant (Node23) 791-- Defined in discriminants of concurrent types. Denotes the homologous 792-- discriminant of the corresponding record type. The CR_Discriminant is 793-- created at the same time as the discriminal, and used to replace 794-- occurrences of the discriminant within the type declaration. 795 796-- Current_Use_Clause (Node27) 797-- Defined in packages and in types. For packages, denotes the use 798-- package clause currently in scope that makes the package use_visible. 799-- For types, it denotes the use_type clause that makes the operators of 800-- the type visible. Used for more precise warning messages on redundant 801-- use clauses. 802 803-- Current_Value (Node9) 804-- Defined in all object entities. Set in E_Variable, E_Constant, formal 805-- parameters and E_Loop_Parameter entities if we have trackable current 806-- values. Set non-Empty if the (constant) current value of the variable 807-- is known, This value is valid only for references from the same 808-- sequential scope as the entity. The sequential scope of an entity 809-- includes the immediate scope and any contained scopes that are package 810-- specs, package bodies, blocks (at any nesting level) or statement 811-- sequences in IF or loop statements. 812-- 813-- Another related use of this field is to record information about the 814-- value obtained from an IF or WHILE statement condition. If the IF or 815-- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ", 816-- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a 817-- Current_Value field, RELOP is one of the six relational operators, and 818-- VAL is a compile-time known value then the Current_Value field of OBJ 819-- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node 820-- of the relevant construct, and the Condition field of this can be 821-- consulted to give information about the value of OBJ. For more details 822-- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition. 823 824-- Debug_Info_Off (Flag166) 825-- Defined in all entities. Set if a pragma Suppress_Debug_Info applies 826-- to the entity, or if internal processing in the compiler determines 827-- that suppression of debug information is desirable. Note that this 828-- flag is only for use by the front end as part of the processing for 829-- determining if Needs_Debug_Info should be set. The backend should 830-- always test Needs_Debug_Info, it should never test Debug_Info_Off. 831 832-- Debug_Renaming_Link (Node25) 833-- Used to link the variable associated with a debug renaming declaration 834-- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for 835-- details of the use of this field. 836 837-- Declaration_Node (synthesized) 838-- Applies to all entities. Returns the tree node for the construct that 839-- declared the entity. Normally this is just the Parent of the entity. 840-- One exception arises with child units, where the parent of the entity 841-- is a selected component/defining program unit name. Another exception 842-- is that if the entity is an incomplete type that has been completed or 843-- a private type, then we obtain the declaration node denoted by the 844-- full type, i.e. the full type declaration node. Also note that for 845-- subprograms, this returns the {function,procedure}_specification, not 846-- the subprogram_declaration. 847 848-- Default_Aspect_Component_Value (Node19) [base type only] 849-- Defined in array types. Holds the static value specified in a 850-- Default_Component_Value aspect specification for the array type, 851-- or inherited on derivation. 852 853-- Default_Aspect_Value (Node19) [base type only] 854-- Defined in scalar types. Holds the static value specified in a 855-- Default_Value aspect specification for the type, or inherited 856-- on derivation. 857 858-- Default_Expr_Function (Node21) 859-- Defined in parameters. It holds the entity of the parameterless 860-- function that is built to evaluate the default expression if it is 861-- more complex than a simple identifier or literal. For the latter 862-- simple cases or if there is no default value, this field is Empty. 863 864-- Default_Expressions_Processed (Flag108) 865-- A flag in subprograms (functions, operators, procedures) and in 866-- entries and entry families used to indicate that default expressions 867-- have been processed and to avoid multiple calls to process the 868-- default expressions (see Freeze.Process_Default_Expressions), which 869-- would not only waste time, but also generate false error messages. 870 871-- Default_Value (Node20) 872-- Defined in formal parameters. Points to the node representing the 873-- expression for the default value for the parameter. Empty if the 874-- parameter has no default value (which is always the case for OUT 875-- and IN OUT parameters in the absence of errors). 876 877-- Delay_Cleanups (Flag114) 878-- Defined in entities that have finalization lists (subprograms 879-- blocks, and tasks). Set if there are pending generic body 880-- instantiations for the corresponding entity. If this flag is 881-- set, then generation of cleanup actions for the corresponding 882-- entity must be delayed, since the insertion of the generic body 883-- may affect cleanup generation (see Inline for further details). 884 885-- Delay_Subprogram_Descriptors (Flag50) 886-- Defined in entities for which exception subprogram descriptors 887-- are generated (subprograms, package declarations and package 888-- bodies). Defined if there are pending generic body instantiations 889-- for the corresponding entity. If this flag is set, then generation 890-- of the subprogram descriptor for the corresponding enities must 891-- be delayed, since the insertion of the generic body may add entries 892-- to the list of handlers. 893-- 894-- Note: for subprograms, Delay_Subprogram_Descriptors is set if and 895-- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a 896-- a block (in which case Delay_Subprogram_Descriptors is set for the 897-- containing subprogram). In addition Delay_Subprogram_Descriptors is 898-- set for a library level package declaration or body which contains 899-- delayed instantiations (in this case the descriptor refers to the 900-- enclosing elaboration procedure). 901 902-- Delta_Value (Ureal18) 903-- Defined in fixed and decimal types. Points to a universal real 904-- that holds value of delta for the type, as given in the declaration 905-- or as inherited by a subtype or derived type. 906 907-- Dependent_Instances (Elist8) 908-- Defined in packages that are instances. Holds list of instances 909-- of inner generics. Used to place freeze nodes for those instances 910-- after that of the current one, i.e. after the corresponding generic 911-- bodies. 912 913-- Depends_On_Private (Flag14) 914-- Defined in all type entities. Set if the type is private or if it 915-- depends on a private type. 916 917-- Derived_Type_Link (Node31) 918-- Defined in all type and subtype entries. Set in a base type if 919-- a derived type declaration is encountered which derives from 920-- this base type or one of its subtypes, and there are already 921-- primitive operations declared. In this case, it references the 922-- entity for the type declared by the derived type declaration. 923-- For example: 924-- 925-- type R is ... 926-- subtype RS is R ... 927-- ... 928-- type G is new RS ... 929-- 930-- In this case, if primitive operations have been declared for R, at 931-- the point of declaration of G, then the Derived_Type_Link of R is set 932-- to point to the entity for G. This is used to generate warnings for 933-- rep clauses that appear later on for R, which might result in an 934-- unexpected implicit conversion operation. 935-- 936-- Note: if there is more than one such derived type, the link will point 937-- to the last one (this is only used in generating warning messages). 938 939-- Designated_Type (synthesized) 940-- Applies to access types. Returns the designated type. Differs from 941-- Directly_Designated_Type in that if the access type refers to an 942-- incomplete type, and the full type is available, then this full type 943-- is returned instead of the incomplete type. 944 945-- DIC_Procedure (synthesized) 946-- Defined in all type entities. Set for a private type and its full view 947-- when the type is subject to pragma Default_Initial_Condition (DIC), or 948-- when the type inherits a DIC pragma from a parent type. Points to the 949-- entity of a procedure which takes a single argument of the given type 950-- and verifies the assertion expression of the DIC pragma at run time. 951 952-- Note: the reason this is marked as a synthesized attribute is that the 953-- way this is stored is as an element of the Subprograms_For_Type field. 954 955-- Digits_Value (Uint17) 956-- Defined in floating point types and subtypes and decimal types and 957-- subtypes. Contains the Digits value specified in the declaration. 958 959-- Direct_Primitive_Operations (Elist10) 960-- Defined in tagged types and subtypes (including synchronized types), 961-- in tagged private types and in tagged incomplete types. Element list 962-- of entities for primitive operations of the tagged type. Not defined 963-- in untagged types. In order to follow the C++ ABI, entities of 964-- primitives that come from source must be stored in this list in the 965-- order of their occurrence in the sources. For incomplete types the 966-- list is always empty. 967-- When expansion is disabled the corresponding record type of a 968-- synchronized type is not constructed. In that case, such types 969-- carry this attribute directly, for ASIS use. 970 971-- Directly_Designated_Type (Node20) 972-- Defined in access types. This field points to the type that is 973-- directly designated by the access type. In the case of an access 974-- type to an incomplete type, this field references the incomplete 975-- type. Directly_Designated_Type is typically used in implementing the 976-- static semantics of the language; in implementing dynamic semantics, 977-- we typically want the full view of the designated type. The function 978-- Designated_Type obtains this full type in the case of access to an 979-- incomplete type. 980 981-- Disable_Controlled (Flag253) 982-- Present in all entities. Set for a controlled type subject to aspect 983-- Disable_Controlled which evaluates to True. This flag is taken into 984-- account in synthesized attribute Is_Controlled. 985 986-- Discard_Names (Flag88) 987-- Defined in types and exception entities. Set if pragma Discard_Names 988-- applies to the entity. It is also set for declarative regions and 989-- package specs for which a Discard_Names pragma with zero arguments 990-- has been encountered. The purpose of setting this flag is to be able 991-- to set the Discard_Names attribute on enumeration types declared 992-- after the pragma within the same declarative region. This flag is 993-- set to False if a Keep_Names pragma appears for an enumeration type. 994 995-- Discriminal (Node17) 996-- Defined in discriminants (Discriminant formal: GNAT's first 997-- coinage). The entity used as a formal parameter that corresponds 998-- to a discriminant. See section "Handling of Discriminants" for 999-- full details of the use of discriminals. 1000 1001-- Discriminal_Link (Node10) 1002-- Defined in E_In_Parameter or E_Constant entities. For discriminals, 1003-- points back to corresponding discriminant. For other entities, must 1004-- remain Empty. 1005 1006-- Discriminant_Checking_Func (Node20) 1007-- Defined in components. Points to the defining identifier of the 1008-- function built by the expander returns a Boolean indicating whether 1009-- the given record component exists for the current discriminant 1010-- values. 1011 1012-- Discriminant_Constraint (Elist21) 1013-- Defined in entities whose Has_Discriminants flag is set (concurrent 1014-- types, subtypes, record types and subtypes, private types and 1015-- subtypes, limited private types and subtypes and incomplete types). 1016-- It is an error to reference the Discriminant_Constraint field if 1017-- Has_Discriminants is False. 1018-- 1019-- If the Is_Constrained flag is set, Discriminant_Constraint points 1020-- to an element list containing the discriminant constraints in the 1021-- same order in which the discriminants are declared. 1022-- 1023-- If the Is_Constrained flag is not set but the discriminants of the 1024-- unconstrained type have default initial values then this field 1025-- points to an element list giving these default initial values in 1026-- the same order in which the discriminants are declared. Note that 1027-- in this case the entity cannot be a tagged record type, because 1028-- discriminants in this case cannot have defaults. 1029-- 1030-- If the entity is a tagged record implicit type, then this field is 1031-- inherited from the first subtype (so that the itype is subtype 1032-- conformant with its first subtype, which is needed when the first 1033-- subtype overrides primitive operations inherited by the implicit 1034-- base type). 1035-- 1036-- In all other cases Discriminant_Constraint contains the empty 1037-- Elist (i.e. it is initialized with a call to New_Elmt_List). 1038 1039-- Discriminant_Default_Value (Node20) 1040-- Defined in discriminants. Points to the node representing the 1041-- expression for the default value of the discriminant. Set to 1042-- Empty if the discriminant has no default value. 1043 1044-- Discriminant_Number (Uint15) 1045-- Defined in discriminants. Gives the ranking of a discriminant in 1046-- the list of discriminants of the type, i.e. a sequential integer 1047-- index starting at 1 and ranging up to number of discriminants. 1048 1049-- Dispatch_Table_Wrappers (Elist26) [implementation base type only] 1050-- Defined in E_Record_Type and E_Record_Subtype entities. Set in library 1051-- level tagged type entities if we are generating statically allocated 1052-- dispatch tables. Points to the list of dispatch table wrappers 1053-- associated with the tagged type. For an untagged record, contains 1054-- No_Elist. 1055 1056-- DTC_Entity (Node16) 1057-- Defined in function and procedure entities. Set to Empty unless 1058-- the subprogram is dispatching in which case it references the 1059-- Dispatch Table pointer Component. For regular Ada tagged this, this 1060-- is the _Tag component. For CPP_Class types and their descendants, 1061-- this points to the component entity in the record that holds the 1062-- Vtable pointer for the Vtable containing the entry referencing the 1063-- subprogram. 1064 1065-- DT_Entry_Count (Uint15) 1066-- Defined in E_Component entities. Only used for component marked 1067-- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table) 1068 1069-- DT_Offset_To_Top_Func (Node25) 1070-- Defined in E_Component entities. Only used for component marked 1071-- Is_Tag. If present it stores the Offset_To_Top function used to 1072-- provide this value in tagged types whose ancestor has discriminants. 1073 1074-- DT_Position (Uint15) 1075-- Defined in function and procedure entities which are dispatching 1076-- (should not be referenced without first checking that flag 1077-- Is_Dispatching_Operation is True). Contains the offset into 1078-- the Vtable for the entry that references the subprogram. 1079 1080-- Ekind (Ekind) 1081-- Defined in all entities. Contains a value of the enumeration type 1082-- Entity_Kind declared in a subsequent section in this spec. 1083 1084-- Elaborate_Body_Desirable (Flag210) 1085-- Defined in package entities. Set if the elaboration circuitry detects 1086-- a case where there is a package body that modifies one or more visible 1087-- entities in the package spec and there is no explicit Elaborate_Body 1088-- pragma for the package. This information is passed on to the binder, 1089-- which attempts, but does not promise, to elaborate the body as close 1090-- to the spec as possible. 1091 1092-- Elaboration_Entity (Node13) 1093-- Defined in entry, entry family, [generic] package, and subprogram 1094-- entities. This is a counter associated with the unit that is initially 1095-- set to zero, is incremented when an elaboration request for the unit 1096-- is made, and is decremented when a finalization request for the unit 1097-- is made. This is used for three purposes. First, it is used to 1098-- implement access before elaboration checks (the counter must be 1099-- non-zero to call a subprogram at elaboration time). Second, it is 1100-- used to guard against repeated execution of the elaboration code. 1101-- Third, it is used to ensure that the finalization code is executed 1102-- only after all clients have requested it. 1103-- 1104-- Note that we always allocate this counter, and set this field, but 1105-- we do not always actually use it. It is only used if it is needed 1106-- for access before elaboration use (see Elaboration_Entity_Required 1107-- flag) or if either the spec or the body has elaboration code. If 1108-- neither of these two conditions holds, then the entity is still 1109-- allocated (since we don't know early enough whether or not there 1110-- is elaboration code), but is simply not used for any purpose. 1111 1112-- Elaboration_Entity_Required (Flag174) 1113-- Defined in entry, entry family, [generic] package, and subprogram 1114-- entities. Set only if Elaboration_Entity is non-Empty to indicate that 1115-- the counter is required to be non-zero even if there is no other 1116-- elaboration code. This occurs when the Elaboration_Entity counter 1117-- is used for access before elaboration checks. If the counter is 1118-- only used to prevent multiple execution of the elaboration code, 1119-- then if there is no other elaboration code, obviously there is no 1120-- need to set the flag. 1121 1122-- Encapsulating_State (Node32) 1123-- Defined in abstract state, constant and variable entities. Contains 1124-- the entity of an ancestor state or a single concurrent type whose 1125-- refinement utilizes this item as a constituent. 1126 1127-- Enclosing_Scope (Node18) 1128-- Defined in labels. Denotes the innermost enclosing construct that 1129-- contains the label. Identical to the scope of the label, except for 1130-- labels declared in the body of an accept statement, in which case the 1131-- entry_name is the Enclosing_Scope. Used to validate goto's within 1132-- accept statements. 1133 1134-- Entry_Accepted (Flag152) 1135-- Defined in E_Entry and E_Entry_Family entities. Set if there is 1136-- at least one accept for this entry in the task body. Used to 1137-- generate warnings for missing accepts. 1138 1139-- Entry_Bodies_Array (Node19) 1140-- Defined in protected types for which Has_Entries is true. 1141-- This is the defining identifier for the array of entry body 1142-- action procedures and barrier functions used by the runtime to 1143-- execute the user code associated with each entry. 1144 1145-- Entry_Cancel_Parameter (Node23) 1146-- Defined in blocks. This only applies to a block statement for 1147-- which the Is_Asynchronous_Call_Block flag is set. It 1148-- contains the defining identifier of an object that must be 1149-- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call 1150-- call in the cleanup handler added to the block by 1151-- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean 1152-- object for task entry calls and a Communications_Block object 1153-- in the case of protected entry calls. In both cases the objects 1154-- are declared in outer scopes to this block. 1155 1156-- Entry_Component (Node11) 1157-- Defined in formal parameters (in, in out and out parameters). Used 1158-- only for formals of entries. References the corresponding component 1159-- of the entry parameter record for the entry. 1160 1161-- Entry_Formal (Node16) 1162-- Defined in components of the record built to correspond to entry 1163-- parameters. This field points from the component to the formal. It 1164-- is the back pointer corresponding to Entry_Component. 1165 1166-- Entry_Index_Constant (Node18) 1167-- Defined in an entry index parameter. This is an identifier that 1168-- eventually becomes the name of a constant representing the index 1169-- of the entry family member whose entry body is being executed. Used 1170-- to expand references to the entry index specification identifier. 1171 1172-- Entry_Index_Type (synthesized) 1173-- Applies to an entry family. Denotes Etype of the subtype indication 1174-- in the entry declaration. Used to resolve the index expression in an 1175-- accept statement for a member of the family, and in the prefix of 1176-- 'COUNT when it applies to a family member. 1177 1178-- Entry_Max_Queue_Lengths_Array (Node35) 1179-- Defined in protected types for which Has_Entries is true. Contains the 1180-- defining identifier for the array of naturals used by the runtime to 1181-- limit the queue size of each entry individually. 1182 1183-- Entry_Parameters_Type (Node15) 1184-- Defined in entries. Points to the access-to-record type that is 1185-- constructed by the expander to hold a reference to the parameter 1186-- values. This reference is manipulated (as an address) by the 1187-- tasking runtime. The designated record represents a packaging 1188-- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration 1189-- for further details). Entry_Parameters_Type is Empty if the entry 1190-- has no parameters. 1191 1192-- Enumeration_Pos (Uint11) 1193-- Defined in enumeration literals. Contains the position number 1194-- corresponding to the value of the enumeration literal. 1195 1196-- Enumeration_Rep (Uint12) 1197-- Defined in enumeration literals. Contains the representation that 1198-- corresponds to the value of the enumeration literal. Note that 1199-- this is normally the same as Enumeration_Pos except in the presence 1200-- of representation clauses, where Pos will still represent the 1201-- position of the literal within the type and Rep will have be the 1202-- value given in the representation clause. 1203 1204-- Enumeration_Rep_Expr (Node22) 1205-- Defined in enumeration literals. Points to the expression in an 1206-- associated enumeration rep clause that provides the representation 1207-- value for this literal. Empty if no enumeration rep clause for this 1208-- literal (or if rep clause does not have an entry for this literal, 1209-- an error situation). This is also used to catch duplicate entries 1210-- for the same literal. 1211 1212-- Enum_Pos_To_Rep (Node23) 1213-- Defined in enumeration types (but not enumeration subtypes). Set to 1214-- Empty unless the enumeration type has a non-standard representation 1215-- (i.e. at least one literal has a representation value different from 1216-- its pos value). In this case, Enum_Pos_To_Rep is the entity for an 1217-- array constructed when the type is frozen that maps Pos values to 1218-- corresponding Rep values. The index type of this array is Natural, 1219-- and the component type is a suitable integer type that holds the 1220-- full range of representation values. 1221 1222-- Equivalent_Type (Node18) 1223-- Defined in class wide types and subtypes, access to protected 1224-- subprogram types, and in exception types. For a classwide type, it 1225-- is always Empty. For a class wide subtype, it points to an entity 1226-- created by the expander which gives the backend an understandable 1227-- equivalent of the class subtype with a known size (given by an 1228-- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further 1229-- details. For E_Exception_Type, this points to the record containing 1230-- the data necessary to represent exceptions (for further details, see 1231-- System.Standard_Library. For access_to_protected subprograms, it 1232-- denotes a record that holds pointers to the operation and to the 1233-- protected object. For remote Access_To_Subprogram types, it denotes 1234-- the record that is the fat pointer representation of an RAST. 1235 1236-- Esize (Uint12) 1237-- Defined in all types and subtypes, and also for components, constants, 1238-- and variables, including exceptions where it refers to the static data 1239-- allocated for an exception. Contains the Object_Size of the type or of 1240-- the object. A value of zero indicates that the value is not yet known. 1241-- 1242-- For the case of components where a component clause is present, the 1243-- value is the value from the component clause, which must be non- 1244-- negative (but may be zero, which is acceptable for the case of 1245-- a type with only one possible value). It is also possible for Esize 1246-- of a component to be set without a component clause defined, which 1247-- means that the component size is specified, but not the position. 1248-- See also RM_Size and the section on "Handling of Type'Size Values". 1249-- During backend processing, the value is back annotated for all zero 1250-- values, so that after the call to the backend, the value is set. 1251 1252-- Etype (Node5) 1253-- Defined in all entities. Represents the type of the entity, which 1254-- is itself another entity. For a type entity, points to the parent 1255-- type for a derived type, or if the type is not derived, points to 1256-- itself. For a subtype entity, Etype points to the base type. For 1257-- a class wide type, points to the corresponding specific type. For a 1258-- subprogram or subprogram type, Etype has the return type of a function 1259-- or is set to Standard_Void_Type to represent a procedure. The Etype 1260-- field of a package is also set to Standard_Void_Type. 1261-- 1262-- Note one obscure case: for pragma Default_Storage_Pool (null), the 1263-- Etype of the N_Null node is Empty. 1264 1265-- Extra_Accessibility (Node13) 1266-- Defined in formal parameters in the non-generic case. Normally Empty, 1267-- but if expansion is active, and a parameter is one for which a 1268-- dynamic accessibility check is required, then an extra formal of type 1269-- Natural is created (see description of field Extra_Formal), and the 1270-- Extra_Accessibility field of the formal parameter points to the entity 1271-- for this extra formal. Also defined in variables when compiling 1272-- receiving stubs. In this case, a non Empty value means that this 1273-- variable's accessibility depth has been transmitted by the caller and 1274-- must be retrieved through the entity designed by this field instead of 1275-- being computed. 1276 1277-- Extra_Accessibility_Of_Result (Node19) 1278-- Defined in (non-generic) Function, Operator, and Subprogram_Type 1279-- entities. Normally Empty, but if expansion is active, and a function 1280-- is one for which "the accessibility level of the result ... determined 1281-- by the point of call" (AI05-0234) is needed, then an extra formal of 1282-- subtype Natural is created (see description of field Extra_Formal), 1283-- and the Extra_Accessibility_Of_Result field of the function points to 1284-- the entity for this extra formal. 1285 1286-- Extra_Constrained (Node23) 1287-- Defined in formal parameters in the non-generic case. Normally Empty, 1288-- but if expansion is active and a parameter is one for which a dynamic 1289-- indication of its constrained status is required, then an extra formal 1290-- of type Boolean is created (see description of field Extra_Formal), 1291-- and the Extra_Constrained field of the formal parameter points to the 1292-- entity for this extra formal. Also defined in variables when compiling 1293-- receiving stubs. In this case, a non empty value means that this 1294-- variable's constrained status has been transmitted by the caller and 1295-- must be retrieved through the entity designed by this field instead of 1296-- being computed. 1297 1298-- Extra_Formal (Node15) 1299-- Defined in formal parameters in the non-generic case. Certain 1300-- parameters require extra implicit information to be passed (e.g. the 1301-- flag indicating if an unconstrained variant record argument is 1302-- constrained, and the accessibility level for access parameters). See 1303-- description of Extra_Constrained, Extra_Accessibility fields for 1304-- further details. Extra formal parameters are constructed to represent 1305-- these values, and chained to the end of the list of formals using the 1306-- Extra_Formal field (i.e. the Extra_Formal field of the last "real" 1307-- formal points to the first extra formal, and the Extra_Formal field of 1308-- each extra formal points to the next one, with Empty indicating the 1309-- end of the list of extra formals). Another case of Extra_Formal arises 1310-- in connection with unnesting of subprograms, where the ARECnF formal 1311-- that represents an activation record pointer is an extra formal. 1312 1313-- Extra_Formals (Node28) 1314-- Applies to subprograms, subprogram types, entries, and entry 1315-- families. Returns first extra formal of the subprogram or entry. 1316-- Returns Empty if there are no extra formals. 1317 1318-- Finalization_Master (Node23) [root type only] 1319-- Defined in access-to-controlled or access-to-class-wide types. The 1320-- field contains the entity of the finalization master which handles 1321-- dynamically allocated controlled objects referenced by the access 1322-- type. Empty for access-to-subprogram types. Empty for access types 1323-- whose designated type does not need finalization actions. 1324 1325-- Finalize_Storage_Only (Flag158) [base type only] 1326-- Defined in all types. Set on direct controlled types to which a 1327-- valid Finalize_Storage_Only pragma applies. This flag is also set on 1328-- composite types when they have at least one controlled component and 1329-- all their controlled components are Finalize_Storage_Only. It is also 1330-- inherited by type derivation except for direct controlled types where 1331-- the Finalize_Storage_Only pragma is required at each level of 1332-- derivation. 1333 1334-- Finalizer (Node28) 1335-- Applies to package declarations and bodies. Contains the entity of the 1336-- library-level program which finalizes all package-level controlled 1337-- objects. 1338 1339-- First_Component (synthesized) 1340-- Applies to incomplete, private, protected, record and task types. 1341-- Returns the first component by following the chain of declared 1342-- entities for the type a component is found (one with an Ekind of 1343-- E_Component). The discriminants are skipped. If the record is null, 1344-- then Empty is returned. 1345 1346-- First_Component_Or_Discriminant (synthesized) 1347-- Similar to First_Component, but discriminants are not skipped, so will 1348-- find the first discriminant if discriminants are present. 1349 1350-- First_Entity (Node17) 1351-- Defined in all entities which act as scopes to which a list of 1352-- associated entities is attached (blocks, class subtypes and types, 1353-- entries, functions, loops, packages, procedures, protected objects, 1354-- record types and subtypes, private types, task types and subtypes). 1355-- Points to a list of associated entities using the Next_Entity field 1356-- as a chain pointer with Empty marking the end of the list. 1357 1358-- First_Exit_Statement (Node8) 1359-- Defined in E_Loop entity. The exit statements for a loop are chained 1360-- (in reverse order of appearance) using this field to point to the 1361-- first entry in the chain (last exit statement in the loop). The 1362-- entries are chained through the Next_Exit_Statement field of the 1363-- N_Exit_Statement node with Empty marking the end of the list. 1364 1365-- First_Formal (synthesized) 1366-- Applies to subprograms and subprogram types, and also to entries 1367-- and entry families. Returns first formal of the subprogram or entry. 1368-- The formals are the first entities declared in a subprogram or in 1369-- a subprogram type (the designated type of an Access_To_Subprogram 1370-- definition) or in an entry. 1371 1372-- First_Formal_With_Extras (synthesized) 1373-- Applies to subprograms and subprogram types, and also in entries 1374-- and entry families. Returns first formal of the subprogram or entry. 1375-- Returns Empty if there are no formals. The list returned includes 1376-- all the extra formals (see description of Extra_Formals field). 1377 1378-- First_Index (Node17) 1379-- Defined in array types and subtypes. By introducing implicit subtypes 1380-- for the index constraints, we have the same structure for constrained 1381-- and unconstrained arrays, subtype marks and discrete ranges are 1382-- both represented by a subtype. This function returns the tree node 1383-- corresponding to an occurrence of the first index (NOT the entity for 1384-- the type). Subsequent indices are obtained using Next_Index. Note that 1385-- this field is defined for the case of string literal subtypes, but is 1386-- always Empty. 1387 1388-- First_Literal (Node17) 1389-- Defined in all enumeration types, including character and boolean 1390-- types. This field points to the first enumeration literal entity 1391-- for the type (i.e. it is set to First (Literals (N)) where N is 1392-- the enumeration type definition node. A special case occurs with 1393-- standard character and wide character types, where this field is 1394-- Empty, since there are no enumeration literal lists in these cases. 1395-- Note that this field is set in enumeration subtypes, but it still 1396-- points to the first literal of the base type in this case. 1397 1398-- First_Private_Entity (Node16) 1399-- Defined in all entities containing private parts (packages, protected 1400-- types and subtypes, task types and subtypes). The entities on the 1401-- entity chain are in order of declaration, so the entries for private 1402-- entities are at the end of the chain. This field points to the first 1403-- entity for the private part. It is Empty if there are no entities 1404-- declared in the private part or if there is no private part. 1405 1406-- First_Rep_Item (Node6) 1407-- Defined in all entities. If non-empty, points to a linked list of 1408-- representation pragmas nodes and representation clause nodes that 1409-- apply to the entity, linked using Next_Rep_Item, with Empty marking 1410-- the end of the list. In the case of derived types and subtypes, the 1411-- new entity inherits the chain at the point of declaration. This means 1412-- that it is possible to have multiple instances of the same kind of rep 1413-- item on the chain, in which case it is the first one that applies to 1414-- the entity. 1415-- 1416-- Note: pragmas that can apply to more than one overloadable entity, 1417-- (Convention, Interface, Inline, Inline_Always, Import, Export, 1418-- External) are never present on this chain when they apply to 1419-- overloadable entities, since it is impossible for a given pragma 1420-- to be on more than one chain at a time. 1421-- 1422-- For most representation items, the representation information is 1423-- reflected in other fields and flags in the entity. For example if a 1424-- record representation clause is present, the component entities 1425-- reflect the specified information. However, there are some items that 1426-- are only reflected in the chain. These include: 1427-- 1428-- Machine_Attribute pragma 1429-- Link_Alias pragma 1430-- Linker_Constructor pragma 1431-- Linker_Destructor pragma 1432-- Weak_External pragma 1433-- Thread_Local_Storage pragma 1434-- 1435-- If any of these items are present, then the flag Has_Gigi_Rep_Item is 1436-- set, indicating that the backend should search the chain. 1437-- 1438-- Other representation items are included in the chain so that error 1439-- messages can easily locate the relevant nodes for posting errors. 1440-- Note in particular that size clauses are defined only for this 1441-- purpose, and should only be accessed if Has_Size_Clause is set. 1442 1443-- Float_Rep (Uint10) 1444-- Defined in floating-point entities. Contains a value of type 1445-- Float_Rep_Kind. Together with the Digits_Value uniquely defines 1446-- the floating-point representation to be used. 1447 1448-- Freeze_Node (Node7) 1449-- Defined in all entities. If there is an associated freeze node for the 1450-- entity, this field references this freeze node. If no freeze node is 1451-- associated with the entity, then this field is Empty. See package 1452-- Freeze for further details. 1453 1454-- From_Limited_With (Flag159) 1455-- Defined in abtract states, package and type entities. Set to True when 1456-- the related entity is generated by the expansion of a limited with 1457-- clause. Such an entity is said to be a "shadow" - it acts as the 1458-- abstract view of a state or variable or as the incomplete view of a 1459-- type by inheriting relevant attributes from the said entity. 1460 1461-- Full_View (Node11) 1462-- Defined in all type and subtype entities and in deferred constants. 1463-- References the entity for the corresponding full type or constant 1464-- declaration. For all types other than private and incomplete types, 1465-- this field always contains Empty. If an incomplete type E1 is 1466-- completed by a private type E2 whose full type declaration entity is 1467-- E3 then the full view of E1 is E2, and the full view of E2 is E3. See 1468-- also Underlying_Type. 1469 1470-- Generic_Homonym (Node11) 1471-- Defined in generic packages. The generic homonym is the entity of 1472-- a renaming declaration inserted in every generic unit. It is used 1473-- to resolve the name of a local entity that is given by a qualified 1474-- name, when the generic entity itself is hidden by a local name. 1475 1476-- Generic_Renamings (Elist23) 1477-- Defined in package and subprogram instances. Holds mapping that 1478-- associates generic parameters with the corresponding instances, in 1479-- those cases where the instance is an entity. 1480 1481-- Handler_Records (List10) 1482-- Defined in subprogram and package entities. Points to a list of 1483-- identifiers referencing the handler record entities for the 1484-- corresponding unit. 1485 1486-- Has_Aliased_Components (Flag135) [implementation base type only] 1487-- Defined in array type entities. Indicates that the component type 1488-- of the array is aliased. Should this also be set for records to 1489-- indicate that at least one component is aliased (see processing in 1490-- Sem_Prag.Process_Atomic_Independent_Shared_Volatile???) 1491 1492-- Has_Alignment_Clause (Flag46) 1493-- Defined in all type entities and objects. Indicates if an alignment 1494-- clause has been given for the entity. If set, then Alignment_Clause 1495-- returns the N_Attribute_Definition node for the alignment attribute 1496-- definition clause. Note that it is possible for this flag to be False 1497-- even when Alignment_Clause returns non_Empty (this happens in the case 1498-- of derived type declarations). 1499 1500-- Has_All_Calls_Remote (Flag79) 1501-- Defined in all library unit entities. Set if the library unit has an 1502-- All_Calls_Remote pragma. Note that such entities must also be RCI 1503-- entities, so the flag Is_Remote_Call_Interface will always be set if 1504-- this flag is set. 1505 1506-- Has_Atomic_Components (Flag86) [implementation base type only] 1507-- Defined in all types and objects. Set only for an array type or 1508-- an array object if a valid pragma Atomic_Components applies to the 1509-- type or object. Note that in the case of an object, this flag is 1510-- only set on the object if there was an explicit pragma for the 1511-- object. In other words, the proper test for whether an object has 1512-- atomic components is to see if either the object or its base type 1513-- has this flag set. Note that in the case of a type, the pragma will 1514-- be chained to the rep item chain of the first subtype in the usual 1515-- manner. 1516 1517-- Has_Attach_Handler (synthesized) 1518-- Applies to record types that are constructed by the expander to 1519-- represent protected types. Returns True if there is at least one 1520-- Attach_Handler pragma in the corresponding specification. 1521 1522-- Has_Biased_Representation (Flag139) 1523-- Defined in discrete types (where it applies to the type'size value), 1524-- and to objects (both stand-alone and components), where it applies to 1525-- the size of the object from a size or record component clause. In 1526-- all cases it indicates that the size in question is smaller than 1527-- would normally be required, but that the size requirement can be 1528-- satisfied by using a biased representation, in which stored values 1529-- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to 1530-- reduce the required size. For example, a type with a range of 1..2 1531-- takes one bit, using 0 to represent 1 and 1 to represent 2. 1532-- 1533-- Note that in the object and component cases, the flag is only set if 1534-- the type is unbiased, but the object specifies a smaller size than the 1535-- size of the type, forcing biased representation for the object, but 1536-- the subtype is still an unbiased type. 1537 1538-- Has_Completion (Flag26) 1539-- Defined in all entities that require a completion (functions, 1540-- procedures, private types, limited private types, incomplete types, 1541-- constants and packages that require a body). The flag is set if the 1542-- completion has been encountered and analyzed. 1543 1544-- Has_Completion_In_Body (Flag71) 1545-- Defined in all entities for types and subtypes. Set only in "Taft 1546-- amendment types" (incomplete types whose full declaration appears in 1547-- the package body). 1548 1549-- Has_Complex_Representation (Flag140) [implementation base type only] 1550-- Defined in record types. Set only for a base type to which a valid 1551-- pragma Complex_Representation applies. 1552 1553-- Has_Component_Size_Clause (Flag68) [implementation base type only] 1554-- Defined in all type entities. Set if a component size clause is 1555-- Defined for the given type. Note that this flag can be False even 1556-- if Component_Size is non-zero (happens in the case of derived types). 1557 1558-- Has_Constrained_Partial_View (Flag187) 1559-- Defined in private type and their completions, when the private 1560-- type has no discriminants and the full view has discriminants with 1561-- defaults. In Ada 2005 heap-allocated objects of such types are not 1562-- constrained, and can change their discriminants with full assignment. 1563-- 1564-- Ada 2012 has an additional rule (3.3. (23/10.3)) concerning objects 1565-- declared in a generic package body. Objects whose type is an untagged 1566-- generic formal private type are considered to have a constrained 1567-- partial view. The predicate Object_Type_Has_Constrained_Partial_View 1568-- in sem_aux is used to test for this case. 1569 1570-- Has_Contiguous_Rep (Flag181) 1571-- Defined in enumeration types. Set if the type as a representation 1572-- clause whose entries are successive integers. 1573 1574-- Has_Controlled_Component (Flag43) [base type only] 1575-- Defined in all type and subtype entities. Set only for composite type 1576-- entities which contain a component that either is a controlled type, 1577-- or itself contains controlled component (i.e. either Is_Controlled or 1578-- Has_Controlled_Component is set for at least one component). 1579 1580-- Has_Controlling_Result (Flag98) 1581-- Defined in E_Function entities. Set if the function is a primitive 1582-- function of a tagged type which can dispatch on result. 1583 1584-- Has_Convention_Pragma (Flag119) 1585-- Defined in all entities. Set for an entity for which a valid pragma 1586-- Convention, Import, or Export has been given. Used to prevent more 1587-- than one such pragma appearing for a given entity (RM B.1(45)). 1588 1589-- Has_Default_Aspect (Flag39) [base type only] 1590-- Defined in entities for types and subtypes, set for scalar types with 1591-- a Default_Value aspect and array types with a Default_Component_Value 1592-- aspect. If this flag is set, then a corresponding aspect specification 1593-- node will be present on the rep item chain for the entity. For a 1594-- derived type that inherits a default from its ancestor, the default 1595-- value is set, but it may be overridden by an aspect declaration on 1596-- type derivation. 1597 1598-- Has_Delayed_Aspects (Flag200) 1599-- Defined in all entities. Set if the Rep_Item chain for the entity has 1600-- one or more N_Aspect_Definition nodes chained which are not to be 1601-- evaluated till the freeze point. The aspect definition expression 1602-- clause has been preanalyzed to get visibility at the point of use, 1603-- but no other action has been taken. 1604 1605-- Has_Delayed_Freeze (Flag18) 1606-- Defined in all entities. Set to indicate that an explicit freeze 1607-- node must be generated for the entity at its freezing point. See 1608-- separate section ("Delayed Freezing and Elaboration") for details. 1609 1610-- Has_Delayed_Rep_Aspects (Flag261) 1611-- Defined in all types and subtypes. This flag is set if there is at 1612-- least one aspect for a representation characteristic that has to be 1613-- delayed and is one of the characteristics that may be inherited by 1614-- types derived from this type if not overridden. If this flag is set, 1615-- then types derived from this type have May_Inherit_Delayed_Rep_Aspects 1616-- set, signalling that Freeze.Inherit_Delayed_Rep_Aspects must be called 1617-- at the freeze point of the derived type. 1618 1619-- Has_DIC (syntherized) 1620-- Defined in all type entities. Set for a private type and its full view 1621-- when the type is subject to pragma Default_Initial_Condition (DIC), or 1622-- when the type inherits a DIC pragma from a parent type. 1623 1624-- Has_Discriminants (Flag5) 1625-- Defined in all types and subtypes. For types that are allowed to have 1626-- discriminants (record types and subtypes, task types and subtypes, 1627-- protected types and subtypes, private types, limited private types, 1628-- and incomplete types), indicates if the corresponding type or subtype 1629-- has a known discriminant part. Always false for all other types. 1630 1631-- Has_Dispatch_Table (Flag220) 1632-- Defined in E_Record_Types that are tagged. Set to indicate that the 1633-- corresponding dispatch table is already built. This flag is used to 1634-- avoid duplicate construction of library level dispatch tables (because 1635-- the declaration of library level objects cause premature construction 1636-- of the table); otherwise the code that builds the table is added at 1637-- the end of the list of declarations of the package. 1638 1639-- Has_Dynamic_Predicate_Aspect (Flag258) 1640-- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect 1641-- was explicitly applied to the type. Generally we treat predicates as 1642-- static if possible, regardless of whether they are specified using 1643-- Predicate, Static_Predicate, or Dynamic_Predicate. And if a predicate 1644-- can be treated as static (i.e. its expression is predicate-static), 1645-- then the flag Has_Static_Predicate will be set True. But there are 1646-- cases where legality is affected by the presence of an explicit 1647-- Dynamic_Predicate aspect. For example, even if a predicate looks 1648-- static, you can't use it in a case statement if there is an explicit 1649-- Dynamic_Predicate aspect specified. So test Has_Static_Predicate if 1650-- you just want to know if the predicate can be evaluated statically, 1651-- but test Has_Dynamic_Predicate_Aspect to enforce legality rules about 1652-- the use of dynamic predicates. 1653 1654-- Has_Entries (synthesized) 1655-- Applies to concurrent types. True if any entries are declared 1656-- within the task or protected definition for the type. 1657 1658-- Has_Enumeration_Rep_Clause (Flag66) 1659-- Defined in enumeration types. Set if an enumeration representation 1660-- clause has been given for this enumeration type. Used to prevent more 1661-- than one enumeration representation clause for a given type. Note 1662-- that this does not imply a representation with holes, since the rep 1663-- clause may merely confirm the default 0..N representation. 1664 1665-- Has_Exit (Flag47) 1666-- Defined in loop entities. Set if the loop contains an exit statement. 1667 1668-- Has_Expanded_Contract (Flag240) 1669-- Defined in functions, procedures, entries, and entry families. Set 1670-- when a subprogram has a N_Contract node that has been expanded. The 1671-- flag prevents double expansion of a contract when a construct is 1672-- rewritten into something else and subsequently reanalyzed/expanded. 1673 1674-- Has_Foreign_Convention (synthesized) 1675-- Applies to all entities. Determines if the Convention for the 1676-- entity is a foreign convention (i.e. is other than Convention_Ada, 1677-- Convention_Intrinsic, Convention_Entry or Convention_Protected). 1678 1679-- Has_Forward_Instantiation (Flag175) 1680-- Defined in package entities. Set for packages that instantiate local 1681-- generic entities before the corresponding generic body has been seen. 1682-- If a package has a forward instantiation, we cannot inline subprograms 1683-- appearing in the same package because the placement requirements of 1684-- the instance will conflict with the linear elaboration of front-end 1685-- inlining. 1686 1687-- Has_Fully_Qualified_Name (Flag173) 1688-- Defined in all entities. Set if the name in the Chars field has been 1689-- replaced by the fully qualified name, as used for debug output. See 1690-- Exp_Dbug for a full description of the use of this flag and also the 1691-- related flag Has_Qualified_Name. 1692 1693-- Has_Gigi_Rep_Item (Flag82) 1694-- Defined in all entities. Set if the rep item chain (referenced by 1695-- First_Rep_Item and linked through the Next_Rep_Item chain) contains a 1696-- representation item that needs to be specially processed by the back 1697-- end, i.e. one of the following items: 1698-- 1699-- Machine_Attribute pragma 1700-- Linker_Alias pragma 1701-- Linker_Constructor pragma 1702-- Linker_Destructor pragma 1703-- Weak_External pragma 1704-- Thread_Local_Storage pragma 1705-- 1706-- If this flag is set, then the backend should scan the rep item chain 1707-- to process any of these items that appear. At least one such item will 1708-- be present. 1709-- 1710-- Has_Homonym (Flag56) 1711-- Defined in all entities. Set if an entity has a homonym in the same 1712-- scope. Used by the backend to generate unique names for all entities. 1713 1714-- Has_Implicit_Dereference (Flag251) 1715-- Defined in types and discriminants. Set if the type has an aspect 1716-- Implicit_Dereference. Set also on the discriminant named in the aspect 1717-- clause, to simplify type resolution. 1718 1719-- Has_Independent_Components (Flag34) [implementation base type only] 1720-- Defined in all types and objects. Set only for a record type or an 1721-- array type or array object if a valid pragma Independent_Components 1722-- applies to the type or object. Note that in the case of an object, 1723-- this flag is only set on the object if there was an explicit pragma 1724-- for the object. In other words, the proper test for whether an object 1725-- has independent components is to see if either the object or its base 1726-- type has this flag set. Note that in the case of a type, the pragma 1727-- will be chained to the rep item chain of the first subtype in the 1728-- usual manner. 1729 1730-- Has_Inheritable_Invariants (Flag248) [base type only] 1731-- Defined in all type entities. Set on private types and interface types 1732-- which define at least one class-wide invariant. Such invariants must 1733-- be inherited by derived types. The flag is also set on the full view 1734-- of a private type for completeness. 1735 1736-- Has_Inherited_DIC (Flag133) [base type only] 1737-- Defined in all type entities. Set for a derived type which inherits 1738-- pragma Default_Initial_Condition from a parent type. 1739 1740-- Has_Inherited_Invariants (Flag291) [base type only] 1741-- Defined in all type entities. Set on private extensions and derived 1742-- types which inherit at least on class-wide invariant from a parent or 1743-- an interface type. The flag is also set on the full view of a private 1744-- extension for completeness. 1745 1746-- Has_Initial_Value (Flag219) 1747-- Defined in entities for variables and out parameters. Set if there 1748-- is an explicit initial value expression in the declaration of the 1749-- variable. Note that this is set only if this initial value is 1750-- explicit, it is not set for the case of implicit initialization 1751-- of access types or controlled types. Always set to False for out 1752-- parameters. Also defined in entities for in and in-out parameters, 1753-- but always false in these cases. 1754 1755-- Has_Interrupt_Handler (synthesized) 1756-- Applies to all protected type entities. Set if the protected type 1757-- definition contains at least one procedure to which a pragma 1758-- Interrupt_Handler applies. 1759 1760-- Has_Invariants (synthesized) 1761-- Defined in all type entities. True if the type defines at least one 1762-- invariant of its own or inherits at least one class-wide invariant 1763-- from a parent type or an interface. 1764 1765-- Has_Loop_Entry_Attributes (Flag260) 1766-- Defined in E_Loop entities. Set when the loop is subject to at least 1767-- one attribute 'Loop_Entry. The flag also implies that the loop has 1768-- already been transformed. See Expand_Loop_Entry_Attribute for details. 1769 1770-- Has_Machine_Radix_Clause (Flag83) 1771-- Defined in decimal types and subtypes, set if a Machine_Radix 1772-- representation clause is present. This flag is used to detect 1773-- the error of multiple machine radix clauses for a single type. 1774 1775-- Has_Master_Entity (Flag21) 1776-- Defined in entities that can appear in the scope stack (see spec 1777-- of Sem). It is set if a task master entity (_master) has been 1778-- declared and initialized in the corresponding scope. 1779 1780-- Has_Missing_Return (Flag142) 1781-- Defined in functions and generic functions. Set if there is one or 1782-- more missing return statements in the function. This is used to 1783-- control wrapping of the body in Exp_Ch6 to ensure that the program 1784-- error exception is correctly raised in this case at run time. 1785 1786-- Has_Nested_Block_With_Handler (Flag101) 1787-- Defined in scope entities. Set if there is a nested block within the 1788-- scope that has an exception handler and the two scopes are in the 1789-- same procedure. This is used by the backend for controlling certain 1790-- optimizations to ensure that they are consistent with exceptions. 1791-- See documentation in backend for further details. 1792 1793-- Has_Nested_Subprogram (Flag282) 1794-- Defined in subprogram entities. Set for a subprogram which contains at 1795-- least one nested subprogram. 1796 1797-- Has_Non_Limited_View (synth) 1798-- Defined in E_Incomplete_Type, E_Incomplete_Subtype, E_Class_Wide_Type, 1799-- E_Abstract_State entities. True if their Non_Limited_View attribute 1800-- is present. 1801 1802-- Has_Non_Null_Abstract_State (synth) 1803-- Defined in package entities. True if the package is subject to a non- 1804-- null Abstract_State aspect/pragma. 1805 1806-- Has_Non_Null_Visible_Refinement (synth) 1807-- Defined in E_Abstract_State entities. True if the state has a visible 1808-- refinement of at least one variable or state constituent as expressed 1809-- in aspect/pragma Refined_State. 1810 1811-- Has_Non_Standard_Rep (Flag75) [implementation base type only] 1812-- Defined in all type entities. Set when some representation clause 1813-- or pragma causes the representation of the item to be significantly 1814-- modified. In this category are changes of small or radix for a 1815-- fixed-point type, change of component size for an array, and record 1816-- or enumeration representation clauses, as well as packed pragmas. 1817-- All other representation clauses (e.g. Size and Alignment clauses) 1818-- are not considered to be significant since they do not affect 1819-- stored bit patterns. 1820 1821-- Has_Null_Abstract_State (synth) 1822-- Defined in package entities. True if the package is subject to a null 1823-- Abstract_State aspect/pragma. 1824 1825-- Has_Null_Visible_Refinement (synth) 1826-- Defined in E_Abstract_State entities. True if the state has a visible 1827-- null refinement as expressed in aspect/pragma Refined_State. 1828 1829-- Has_Object_Size_Clause (Flag172) 1830-- Defined in entities for types and subtypes. Set if an Object_Size 1831-- clause has been processed for the type. Used to prevent multiple 1832-- Object_Size clauses for a given entity. 1833 1834-- Has_Out_Or_In_Out_Parameter (Flag110) 1835-- Present in subprograms, generic subprograms, entries, and entry 1836-- families. Set if they have at least one OUT or IN OUT parameter 1837-- (allowed for functions only in Ada 2012). 1838 1839-- Has_Own_DIC (Flag3) [base type only] 1840-- Defined in all type entities. Set for a private type and its full view 1841-- when the type is subject to pragma Default_Initial_Condition. 1842 1843-- Has_Own_Invariants (Flag232) [base type only] 1844-- Defined in all type entities. Set on any type which defines at least 1845-- one invariant of its own. The flag is also set on the full view of a 1846-- private type for completeness. 1847 1848-- Has_Partial_Visible_Refinement (Flag296) 1849-- Defined in E_Abstract_State entities. Set when a state has at least 1850-- one refinement constituent subject to indicator Part_Of, and analysis 1851-- is in the region between the declaration of the first constituent for 1852-- this abstract state (in the private part of the package) and the end 1853-- of the package spec or body with visibility over this private part 1854-- (which includes the package itself and its child packages). 1855 1856-- Has_Per_Object_Constraint (Flag154) 1857-- Defined in E_Component entities. Set if the subtype of the component 1858-- has a per object constraint. Per object constraints result from the 1859-- following situations : 1860-- 1861-- 1. N_Attribute_Reference - when the prefix is the enclosing type and 1862-- the attribute is Access. 1863-- 2. N_Discriminant_Association - when the expression uses the 1864-- discriminant of the enclosing type. 1865-- 3. N_Index_Or_Discriminant_Constraint - when at least one of the 1866-- individual constraints is a per object constraint. 1867-- 4. N_Range - when the lower or upper bound uses the discriminant of 1868-- the enclosing type. 1869-- 5. N_Range_Constraint - when the range expression uses the 1870-- discriminant of the enclosing type. 1871 1872-- Has_Pragma_Controlled (Flag27) [implementation base type only] 1873-- Defined in access type entities. It is set if a pragma Controlled 1874-- applies to the access type. 1875 1876-- Has_Pragma_Elaborate_Body (Flag150) 1877-- Defined in all entities. Set in compilation unit entities if a 1878-- pragma Elaborate_Body applies to the compilation unit. 1879 1880-- Has_Pragma_Inline (Flag157) 1881-- Defined in all entities. Set for functions and procedures for which a 1882-- pragma Inline or Inline_Always applies to the subprogram. Note that 1883-- this flag can be set even if Is_Inlined is not set. This happens for 1884-- pragma Inline (if Inline_Active is False). In other words, the flag 1885-- Has_Pragma_Inline represents the formal semantic status, and is used 1886-- for checking semantic correctness. The flag Is_Inlined indicates 1887-- whether inlining is actually active for the entity. 1888 1889-- Has_Pragma_Inline_Always (Flag230) 1890-- Defined in all entities. Set for functions and procedures for which a 1891-- pragma Inline_Always applies. Note that if this flag is set, the flag 1892-- Has_Pragma_Inline is also set. 1893 1894-- Has_Pragma_No_Inline (Flag201) 1895-- Defined in all entities. Set for functions and procedures for which a 1896-- pragma No_Inline applies. Note that if this flag is set, the flag 1897-- Has_Pragma_Inline_Always cannot be set. 1898 1899-- Has_Pragma_Ordered (Flag198) [implementation base type only] 1900-- Defined in entities for enumeration types. If set indicates that a 1901-- valid pragma Ordered was given for the type. This flag is inherited 1902-- by derived enumeration types. We don't need to distinguish the derived 1903-- case since we allow multiple occurrences of this pragma anyway. 1904 1905-- Has_Pragma_Pack (Flag121) [implementation base type only] 1906-- Defined in array and record type entities. If set, indicates that a 1907-- valid pragma Pack was given for the type. Note that this flag is not 1908-- inherited by derived type. See also the Is_Packed flag. 1909 1910-- Has_Pragma_Preelab_Init (Flag221) 1911-- Defined in type and subtype entities. If set indicates that a valid 1912-- pragma Preelaborable_Initialization applies to the type. 1913 1914-- Has_Pragma_Pure (Flag203) 1915-- Defined in all entities. If set, indicates that a valid pragma Pure 1916-- was given for the entity. In some cases, we need to test whether 1917-- Is_Pure was explicitly set using this pragma. 1918 1919-- Has_Pragma_Pure_Function (Flag179) 1920-- Defined in all entities. If set, indicates that a valid pragma 1921-- Pure_Function was given for the entity. In some cases, we need to test 1922-- whether Is_Pure was explicitly set using this pragma. We also set 1923-- this flag for some internal entities that we know should be treated 1924-- as pure for optimization purposes. 1925 1926-- Has_Pragma_Thread_Local_Storage (Flag169) 1927-- Defined in all entities. If set, indicates that a valid pragma 1928-- Thread_Local_Storage was given for the entity. 1929 1930-- Has_Pragma_Unmodified (Flag233) 1931-- Defined in all entities. Can only be set for variables (E_Variable, 1932-- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified 1933-- applies to the variable, indicating that no warning should be given 1934-- if the entity is never modified. Note that clients should generally 1935-- not test this flag directly, but instead use function Has_Unmodified. 1936 1937-- Has_Pragma_Unreferenced (Flag180) 1938-- Defined in all entities. Set if a valid pragma Unreferenced applies 1939-- to the entity, indicating that no warning should be given if the 1940-- entity has no references, but a warning should be given if it is 1941-- in fact referenced. For private types, this flag is set in both the 1942-- private entity and full entity if the pragma applies to either. Note 1943-- that clients should generally not test this flag directly, but instead 1944-- use function Has_Unreferenced. 1945 1946-- ??? this real description was clobbered 1947 1948-- Has_Pragma_Unreferenced_Objects (Flag212) 1949-- Defined in all entities. Set if a valid pragma Unused applies to an 1950-- entity, indicating that warnings should be given if the entity is 1951-- modified or referenced. This pragma is equivalent to a pair of 1952-- Unmodified and Unreferenced pragmas. 1953 1954-- Has_Pragma_Unused (Flag294) 1955-- Defined in all entries. Set if a valid pragma Unused applies to a 1956-- variable or entity, indicating that warnings should not be given if 1957-- it is never modified or referenced. Note: This pragma is exactly 1958-- equivalent Unmodified and Unreference combined. 1959 1960-- Has_Predicates (Flag250) 1961-- Defined in type and subtype entities. Set if a pragma Predicate or 1962-- Predicate aspect applies to the type or subtype, or if it inherits a 1963-- Predicate aspect from its parent or progenitor types. 1964-- 1965-- Note: this flag is set on both partial and full view of types to which 1966-- a Predicate pragma or aspect applies. 1967 1968-- Has_Primitive_Operations (Flag120) [base type only] 1969-- Defined in all type entities. Set if at least one primitive operation 1970-- is defined for the type. 1971 1972-- Has_Private_Ancestor (Flag151) 1973-- Applies to type extensions. True if some ancestor is derived from a 1974-- private type, making some components invisible and aggregates illegal. 1975-- This flag is set at the point of derivation. The legality of the 1976-- aggregate must be rechecked because it also depends on the visibility 1977-- at the point the aggregate is resolved. See sem_aggr.adb. This is part 1978-- of AI05-0115. 1979 1980-- Has_Private_Declaration (Flag155) 1981-- Defined in all entities. Set if it is the defining entity of a private 1982-- type declaration or its corresponding full declaration. This flag is 1983-- thus preserved when the full and the partial views are exchanged, to 1984-- indicate if a full type declaration is a completion. Used for semantic 1985-- checks in E.4(18) and elsewhere. 1986 1987-- Has_Private_Extension (Flag300) 1988-- Defined in tagged types. Set to indicate that the tagged type has some 1989-- private extension. Used to report a warning on public primitives added 1990-- after defining its private extensions. 1991 1992-- Has_Protected (Flag271) [base type only] 1993-- Defined in all type entities. Set on protected types themselves, and 1994-- also (recursively) on any composite type which has a component for 1995-- which Has_Protected is set, unless the protected type is declared in 1996-- the private part of an internal unit. The meaning is that restrictions 1997-- for protected types apply to this type. Note: the flag is not set on 1998-- access types, even if they designate an object that Has_Protected. 1999 2000-- Has_Qualified_Name (Flag161) 2001-- Defined in all entities. Set if the name in the Chars field has 2002-- been replaced by its qualified name, as used for debug output. See 2003-- Exp_Dbug for a full description of qualification requirements. For 2004-- some entities, the name is the fully qualified name, but there are 2005-- exceptions. In particular, for local variables in procedures, we 2006-- do not include the procedure itself or higher scopes. See also the 2007-- flag Has_Fully_Qualified_Name, which is set if the name does indeed 2008-- include the fully qualified name. 2009 2010-- Has_RACW (Flag214) 2011-- Defined in package spec entities. Set if the spec contains the 2012-- declaration of a remote access-to-classwide type. 2013 2014-- Has_Record_Rep_Clause (Flag65) [implementation base type only] 2015-- Defined in record types. Set if a record representation clause has 2016-- been given for this record type. Used to prevent more than one such 2017-- clause for a given record type. Note that this is initially cleared 2018-- for a derived type, even though the representation is inherited. See 2019-- also the flag Has_Specified_Layout. 2020 2021-- Has_Recursive_Call (Flag143) 2022-- Defined in procedures. Set if a direct parameterless recursive call 2023-- is detected while analyzing the body. Used to activate some error 2024-- checks for infinite recursion. 2025 2026-- Has_Shift_Operator (Flag267) [base type only] 2027-- Defined in integer types. Set in the base type of an integer type for 2028-- which at least one of the shift operators is defined. 2029 2030-- Has_Size_Clause (Flag29) 2031-- Defined in entities for types and objects. Set if a size clause is 2032-- defined for the entity. Used to prevent multiple Size clauses for a 2033-- given entity. Note that it is always initially cleared for a derived 2034-- type, even though the Size for such a type is inherited from a Size 2035-- clause given for the parent type. 2036 2037-- Has_Small_Clause (Flag67) 2038-- Defined in ordinary fixed point types (but not subtypes). Indicates 2039-- that a small clause has been given for the entity. Used to prevent 2040-- multiple Small clauses for a given entity. Note that it is always 2041-- initially cleared for a derived type, even though the Small for such 2042-- a type is inherited from a Small clause given for the parent type. 2043 2044-- Has_Specified_Layout (Flag100) [implementation base type only] 2045-- Defined in all type entities. Set for a record type or subtype if 2046-- the record layout has been specified by a record representation 2047-- clause. Note that this differs from the flag Has_Record_Rep_Clause 2048-- in that it is inherited by a derived type. Has_Record_Rep_Clause is 2049-- used to indicate that the type is mentioned explicitly in a record 2050-- representation clause, and thus is not inherited by a derived type. 2051-- This flag is always False for non-record types. 2052 2053-- Has_Specified_Stream_Input (Flag190) 2054-- Has_Specified_Stream_Output (Flag191) 2055-- Has_Specified_Stream_Read (Flag192) 2056-- Has_Specified_Stream_Write (Flag193) 2057-- Defined in all type and subtype entities. Set for a given view if the 2058-- corresponding stream-oriented attribute has been defined by an 2059-- attribute definition clause. When such a clause occurs, a TSS is set 2060-- on the underlying full view; the flags are used to track visibility of 2061-- the attribute definition clause for partial or incomplete views. 2062 2063-- Has_Static_Discriminants (Flag211) 2064-- Defined in record subtypes constrained by discriminant values. Set if 2065-- all the discriminant values have static values, meaning that in the 2066-- case of a variant record, the component list can be trimmed down to 2067-- include only the components corresponding to these discriminants. 2068 2069-- Has_Static_Predicate (Flag269) 2070-- Defined in all types and subtypes. Set if the type (which must be a 2071-- scalar type) has a predicate whose expression is predicate-static. 2072-- This can result from the use of any Predicate, Static_Predicate, or 2073-- Dynamic_Predicate aspect. We can distinguish these cases by testing 2074-- Has_Static_Predicate_Aspect and Has_Dynamic_Predicate_Aspect. See 2075-- description of the latter flag for further information on dynamic 2076-- predicates which are also static. 2077 2078-- Has_Static_Predicate_Aspect (Flag259) 2079-- Defined in all types and subtypes. Set if a Static_Predicate aspect 2080-- applies to the type. Note that we can tell if a static predicate is 2081-- present by looking at Has_Static_Predicate, but this could have come 2082-- from a Predicate aspect or pragma or even from a Dynamic_Predicate 2083-- aspect. When we need to know the difference (e.g. to know what set of 2084-- check policies apply, use this flag and Has_Dynamic_Predicate_Aspect 2085-- to determine which case we have). 2086 2087-- Has_Storage_Size_Clause (Flag23) [implementation base type only] 2088-- Defined in task types and access types. It is set if a Storage_Size 2089-- clause is present for the type. Used to prevent multiple clauses for 2090-- one type. Note that this flag is initially cleared for a derived type 2091-- even though the Storage_Size for such a type is inherited from a 2092-- Storage_Size clause given for the parent type. Note that in the case 2093-- of access types, this flag is defined only in the root type, since a 2094-- storage size clause cannot be given to a derived type. 2095 2096-- Has_Stream_Size_Clause (Flag184) 2097-- Defined in all entities. It is set for types which have a Stream_Size 2098-- clause attribute. Used to prevent multiple Stream_Size clauses for a 2099-- given entity, and also whether it is necessary to check for a stream 2100-- size clause. 2101 2102-- Has_Task (Flag30) [base type only] 2103-- Defined in all type entities. Set on task types themselves, and also 2104-- (recursively) on any composite type which has a component for which 2105-- Has_Task is set. The meaning is that an allocator or declaration of 2106-- such an object must create the required tasks. Note: the flag is not 2107-- set on access types, even if they designate an object that Has_Task. 2108 2109-- Has_Timing_Event (Flag289) [base type only] 2110-- Defined in all type entities. Set on language defined type 2111-- Ada.Real_Time.Timing_Events.Timing_Event, and also (recursively) on 2112-- any composite type which has a component for which Has_Timing_Event 2113-- is set. Used for the No_Local_Timing_Event restriction. 2114 2115-- Has_Thunks (Flag228) 2116-- Applies to E_Constant entities marked Is_Tag. True for secondary tag 2117-- referencing a dispatch table whose contents are pointers to thunks. 2118 2119-- Has_Unchecked_Union (Flag123) [base type only] 2120-- Defined in all type entities. Set on unchecked unions themselves 2121-- and (recursively) on any composite type which has a component for 2122-- which Has_Unchecked_Union is set. The meaning is that a comparison 2123-- operation or 'Valid_Scalars reference for the type is not permitted. 2124-- Note that the flag is not set on access types, even if they designate 2125-- an object that has the flag Has_Unchecked_Union set. 2126 2127-- Has_Unknown_Discriminants (Flag72) 2128-- Defined in all entities. Set for types with unknown discriminants. 2129-- Types can have unknown discriminants either from their declaration or 2130-- through type derivation. The use of this flag exactly meets the spec 2131-- in RM 3.7(26). Note that all class-wide types are considered to have 2132-- unknown discriminants. Note that both flags Has_Discriminants and 2133-- Has_Unknown_Discriminants may be true for a type. Class-wide types and 2134-- their subtypes have unknown discriminants and can have declared ones 2135-- as well. Private types declared with unknown discriminants may have a 2136-- full view that has explicit discriminants, and both flag will be set 2137-- on the partial view, to ensure that discriminants are properly 2138-- inherited in certain contexts. 2139 2140-- Has_Visible_Refinement (Flag263) 2141-- Defined in E_Abstract_State entities. Set when a state has at least 2142-- one refinement constituent and analysis is in the region between 2143-- pragma Refined_State and the end of the package body declarations. 2144 2145-- Has_Volatile_Components (Flag87) [implementation base type only] 2146-- Defined in all types and objects. Set only for an array type or array 2147-- object if a valid pragma Volatile_Components or a valid pragma 2148-- Atomic_Components applies to the type or object. Note that in the case 2149-- of an object, this flag is only set on the object if there was an 2150-- explicit pragma for the object. In other words, the proper test for 2151-- whether an object has volatile components is to see if either the 2152-- object or its base type has this flag set. Note that in the case of a 2153-- type the pragma will be chained to the rep item chain of the first 2154-- subtype in the usual manner. 2155 2156-- Has_Xref_Entry (Flag182) 2157-- Defined in all entities. Set if an entity has an entry in the Xref 2158-- information generated in ali files. This is true for all source 2159-- entities in the extended main source file. It is also true of entities 2160-- in other packages that are referenced directly or indirectly from the 2161-- main source file (indirect reference occurs when the main source file 2162-- references an entity with a type reference. See package Lib.Xref for 2163-- further details). 2164 2165-- Hiding_Loop_Variable (Node8) 2166-- Defined in variables. Set only if a variable of a discrete type is 2167-- hidden by a loop variable in the same local scope, in which case 2168-- the Hiding_Loop_Variable field of the hidden variable points to 2169-- the E_Loop_Parameter entity doing the hiding. Used in processing 2170-- warning messages if the hidden variable turns out to be unused 2171-- or is referenced without being set. 2172 2173-- Hidden_In_Formal_Instance (Elist30) 2174-- Defined on actuals for formal packages. Entities on the list are 2175-- formals that are hidden outside of the formal package when this 2176-- package is not declared with a box, or the formal itself is not 2177-- defaulted (see RM 12.7 (10)). Their visibility is restored on exit 2178-- from the current generic, because the actual for the formal package 2179-- may be used subsequently in the current unit. 2180 2181-- Homonym (Node4) 2182-- Defined in all entities. Link for list of entities that have the 2183-- same source name and that are declared in the same or enclosing 2184-- scopes. Homonyms in the same scope are overloaded. Used for name 2185-- resolution and for the generation of debugging information. 2186 2187-- Ignore_SPARK_Mode_Pragmas (Flag301) 2188-- Present in concurrent type, entry, operator, [generic] package, 2189-- package body, [generic] subprogram, and subprogram body entities. 2190-- Set when the entity appears in an instance subject to SPARK_Mode 2191-- "off" and indicates that all SPARK_Mode pragmas found within must 2192-- be ignored. 2193 2194-- Implementation_Base_Type (synthesized) 2195-- Applies to all entities. For types, similar to Base_Type, but never 2196-- returns a private type when applied to a non-private type. Instead in 2197-- this case, it always returns the Underlying_Type of the base type, so 2198-- that we still have a concrete type. For entities other than types, 2199-- returns the entity unchanged. 2200 2201-- Import_Pragma (Node35) 2202-- Defined in subprogram entities. Set if a valid pragma Import or pragma 2203-- Import_Function or pragma Import_Procedure applies to the subprogram, 2204-- in which case this field points to the pragma (we can't use the normal 2205-- Rep_Item chain mechanism, because a single pragma Import can apply 2206-- to multiple subprogram entities). 2207 2208-- In_Package_Body (Flag48) 2209-- Defined in package entities. Set on the entity that denotes the 2210-- package (the defining occurrence of the package declaration) while 2211-- analyzing and expanding the package body. Reset on completion of 2212-- analysis/expansion. 2213 2214-- In_Private_Part (Flag45) 2215-- Defined in all entities. Can be set only in package entities and 2216-- objects. For package entities, this flag is set to indicate that the 2217-- private part of the package is being analyzed. The flag is reset at 2218-- the end of the package declaration. For objects it indicates that the 2219-- declaration of the object occurs in the private part of a package. 2220 2221-- Incomplete_Actuals (Elist24) 2222-- Defined on package entities that are instances. Indicates the actuals 2223-- types in the instantiation that are limited views. If this list is 2224-- not empty, the instantiation, which appears in a package declaration, 2225-- is relocated to the corresponding package body, which must have a 2226-- corresponding nonlimited with_clause. 2227 2228-- Initialization_Statements (Node28) 2229-- Defined in constants and variables. For a composite object initialized 2230-- initialized with an aggregate that has been converted to a sequence 2231-- of assignments, points to a block statement containing the 2232-- assignments. 2233 2234-- Inner_Instances (Elist23) 2235-- Defined in generic units. Contains element list of units that are 2236-- instantiated within the given generic. Used to diagnose circular 2237-- instantiations. 2238 2239-- Interface_Alias (Node25) 2240-- Defined in subprograms that cover a primitive operation of an abstract 2241-- interface type. Can be set only if the Is_Hidden flag is also set, 2242-- since such entities are always hidden. Points to its associated 2243-- interface subprogram. It is used to register the subprogram in 2244-- secondary dispatch table of the interface (Ada 2005: AI-251). 2245 2246-- Interface_Name (Node21) 2247-- Defined in constants, variables, exceptions, functions, procedures, 2248-- and packages. Set to Empty unless an export, import, or interface name 2249-- pragma has explicitly specified an external name, in which case it 2250-- references an N_String_Literal node for the specified external name. 2251-- Note that if this field is Empty, and Is_Imported or Is_Exported is 2252-- set, then the default interface name is the name of the entity, cased 2253-- in a manner that is appropriate to the system in use. Note that 2254-- Interface_Name is ignored if an address clause is present (since it 2255-- is meaningless in this case). 2256 2257-- Interfaces (Elist25) 2258-- Defined in record types and subtypes. List of abstract interfaces 2259-- implemented by a tagged type that are not already implemented by the 2260-- ancestors (Ada 2005: AI-251). 2261 2262-- Invariant_Procedure (synthesized) 2263-- Defined in types and subtypes. Set for private types and their full 2264-- views if one or more [class-wide] invariants apply to the type, or 2265-- when the type inherits class-wide invariants from a parent type or 2266-- an interface, or when the type is an array and its component type is 2267-- subject to an invariant, or when the type is record and contains a 2268-- component subject to an invariant (property is recursive). Points to 2269-- to the entity for a procedure which checks all these invariants. The 2270-- invariant procedure takes a single argument of the given type, and 2271-- returns if the invariant holds, or raises exception Assertion_Error 2272-- with an appropriate message if it does not hold. This attribute is 2273-- defined but always Empty for private subtypes. 2274 2275-- Note: the reason this is marked as a synthesized attribute is that the 2276-- way this is stored is as an element of the Subprograms_For_Type field. 2277 2278-- In_Use (Flag8) 2279-- Defined in packages and types. Set when analyzing a use clause for 2280-- the corresponding entity. Reset at end of corresponding declarative 2281-- part. The flag on a type is also used to determine the visibility of 2282-- the primitive operators of the type. 2283 2284-- Is_Abstract_Subprogram (Flag19) 2285-- Defined in all subprograms and entries. Set for abstract subprograms. 2286-- Always False for enumeration literals and entries. See also 2287-- Requires_Overriding. 2288 2289-- Is_Abstract_Type (Flag146) 2290-- Defined in all types. Set for abstract types. 2291 2292-- Is_Access_Constant (Flag69) 2293-- Defined in access types and subtypes. Indicates that the keyword 2294-- constant was present in the access type definition. 2295 2296-- Is_Access_Protected_Subprogram_Type (synthesized) 2297-- Applies to all types, true for named and anonymous access to 2298-- protected subprograms. 2299 2300-- Is_Access_Type (synthesized) 2301-- Applies to all entities, true for access types and subtypes 2302 2303-- Is_Activation_Record (Flag305) 2304-- Applies to E_In_Parameters generated in Exp_Unst for nested 2305-- subprograms, to mark the added formal that carries the activation 2306-- record created in the enclosing subprogram. 2307 2308-- Is_Actual_Subtype (Flag293) 2309-- Defined on all types, true for the generated constrained subtypes 2310-- that are built for unconstrained composite actuals. 2311 2312-- Is_Ada_2005_Only (Flag185) 2313-- Defined in all entities, true if a valid pragma Ada_05 or Ada_2005 2314-- applies to the entity which specifically names the entity, indicating 2315-- that the entity is Ada 2005 only. Note that this flag is not set if 2316-- the entity is part of a unit compiled with the normal no-argument form 2317-- of pragma Ada_05 or Ada_2005. 2318 2319-- Is_Ada_2012_Only (Flag199) 2320-- Defined in all entities, true if a valid pragma Ada_12 or Ada_2012 2321-- applies to the entity which specifically names the entity, indicating 2322-- that the entity is Ada 2012 only. Note that this flag is not set if 2323-- the entity is part of a unit compiled with the normal no-argument form 2324-- of pragma Ada_12 or Ada_2012. 2325 2326-- Is_Aliased (Flag15) 2327-- Defined in all entities. Set for objects and types whose declarations 2328-- carry the keyword aliased, and on record components that have the 2329-- keyword. For Ada 2012, also applies to formal parameters. 2330 2331-- Is_Array_Type (synthesized) 2332-- Applies to all entities, true for array types and subtypes 2333 2334-- Is_Asynchronous (Flag81) 2335-- Defined in all type entities and in procedure entities. Set 2336-- if a pragma Asynchronous applies to the entity. 2337 2338-- Is_Atomic (Flag85) 2339-- Defined in all type entities, and also in constants, components, and 2340-- variables. Set if a pragma Atomic or Shared applies to the entity. 2341-- In the case of private and incomplete types, this flag is set in 2342-- both the partial view and the full view. 2343 2344-- Is_Atomic_Or_VFA (synth) 2345-- Defined in all type entities, and also in constants, components and 2346-- variables. Set if a pragma Atomic or Shared or Volatile_Full_Access 2347-- applies to the entity. For many purposes VFA objects should be treated 2348-- the same as Atomic objects, and this predicate is intended for that 2349-- usage. In the case of private and incomplete types, the predicate 2350-- applies to both the partial view and the full view. 2351 2352-- Is_Base_Type (synthesized) 2353-- Applies to type and subtype entities. True if entity is a base type. 2354 2355-- Is_Bit_Packed_Array (Flag122) [implementation base type only] 2356-- Defined in all entities. This flag is set for a packed array type that 2357-- is bit-packed (i.e. the component size is known by the front end and 2358-- is in the range 1-63 but not a multiple of 8). Is_Packed is always set 2359-- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be 2360-- set without Is_Bit_Packed_Array if the component size is not known by 2361-- the front-end or for the case of an array having one or more index 2362-- types that are enumeration types with non-standard representation. 2363 2364-- Is_Boolean_Type (synthesized) 2365-- Applies to all entities, true for boolean types and subtypes, 2366-- i.e. Standard.Boolean and all types ultimately derived from it. 2367 2368-- Is_Called (Flag102) 2369-- Defined in subprograms. Returns true if the subprogram is called 2370-- in the unit being compiled or in a unit in the context. Used for 2371-- inlining. 2372 2373-- Is_Character_Type (Flag63) 2374-- Defined in all entities. Set for character types and subtypes, 2375-- i.e. enumeration types that have at least one character literal. 2376 2377-- Is_Checked_Ghost_Entity (Flag277) 2378-- Applies to all entities. Set for abstract states, [generic] packages, 2379-- [generic] subprograms, components, discriminants, formal parameters, 2380-- objects, package bodies, subprogram bodies, and [sub]types subject to 2381-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2382-- subject to Assertion_Policy Ghost => Check. 2383 2384-- Is_Child_Unit (Flag73) 2385-- Defined in all entities. Set only for defining entities of program 2386-- units that are child units (but False for subunits). 2387 2388-- Is_Class_Wide_Clone (Flag290) 2389-- Defined on subprogram entities. Set for subprograms built in order 2390-- to implement properly the inheritance of class-wide pre- or post- 2391-- conditions when the condition contains calls to other primitives 2392-- of the ancestor type. Used to implement AI12-0195. 2393 2394-- Is_Class_Wide_Equivalent_Type (Flag35) 2395-- Defined in record types and subtypes. Set to True, if the type acts 2396-- as a class-wide equivalent type, i.e. the Equivalent_Type field of 2397-- some class-wide subtype entity references this record type. 2398 2399-- Is_Class_Wide_Type (synthesized) 2400-- Applies to all entities, true for class wide types and subtypes 2401 2402-- Is_Compilation_Unit (Flag149) 2403-- Defined in all entities. Set if the entity is a package or subprogram 2404-- entity for a compilation unit other than a subunit (since we treat 2405-- subunits as part of the same compilation operation as the ultimate 2406-- parent, we do not consider them to be separate units for this flag). 2407 2408-- Is_Completely_Hidden (Flag103) 2409-- Defined on discriminants. Only set on girder discriminants of 2410-- untagged types. When set, the entity is a girder discriminant of a 2411-- derived untagged type which is not directly visible in the derived 2412-- type because the derived type or one of its ancestors have renamed the 2413-- discriminants in the root type. Note: there are girder discriminants 2414-- which are not Completely_Hidden (e.g. discriminants of a root type). 2415 2416-- Is_Composite_Type (synthesized) 2417-- Applies to all entities, true for all composite types and subtypes. 2418-- Either Is_Composite_Type or Is_Elementary_Type (but not both) is true 2419-- of any type. 2420 2421-- Is_Concurrent_Record_Type (Flag20) 2422-- Defined in record types and subtypes. Set if the type was created 2423-- by the expander to represent a task or protected type. For every 2424-- concurrent type, such as record type is constructed, and task and 2425-- protected objects are instances of this record type at run time 2426-- (The backend will replace declarations of the concurrent type using 2427-- the declarations of the corresponding record type). See Exp_Ch9 for 2428-- further details. 2429 2430-- Is_Concurrent_Type (synthesized) 2431-- Applies to all entities, true for task types and subtypes and for 2432-- protected types and subtypes. 2433 2434-- Is_Constant_Object (synthesized) 2435-- Applies to all entities, true for E_Constant, E_Loop_Parameter, and 2436-- E_In_Parameter entities. 2437 2438-- Is_Constrained (Flag12) 2439-- Defined in types or subtypes which may have index, discriminant 2440-- or range constraint (i.e. array types and subtypes, record types 2441-- and subtypes, string types and subtypes, and all numeric types). 2442-- Set if the type or subtype is constrained. 2443 2444-- Is_Constr_Subt_For_U_Nominal (Flag80) 2445-- Defined in all types and subtypes. Set only for the constructed 2446-- subtype of an object whose nominal subtype is unconstrained. Note 2447-- that the constructed subtype itself will be constrained. 2448 2449-- Is_Constr_Subt_For_UN_Aliased (Flag141) 2450-- Defined in all types and subtypes. This flag can be set only if 2451-- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in 2452-- addition the object concerned is aliased. This flag is used by 2453-- the backend to determine whether a template must be constructed. 2454 2455-- Is_Constructor (Flag76) 2456-- Defined in function and procedure entities. Set if a pragma 2457-- CPP_Constructor applies to the subprogram. 2458 2459-- Is_Controlled_Active (Flag42) [base type only] 2460-- Defined in all type entities. Indicates that the type is controlled, 2461-- i.e. is either a descendant of Ada.Finalization.Controlled or of 2462-- Ada.Finalization.Limited_Controlled. 2463 2464-- Is_Controlled (synth) [base type only] 2465-- Defined in all type entities. Set if Is_Controlled_Active is set for 2466-- the type, and Disable_Controlled is not set. 2467 2468-- Is_Controlling_Formal (Flag97) 2469-- Defined in all Formal_Kind entities. Marks the controlling parameters 2470-- of dispatching operations. 2471 2472-- Is_CPP_Class (Flag74) 2473-- Defined in all type entities, set only for tagged types to which a 2474-- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied. 2475 2476-- Is_Decimal_Fixed_Point_Type (synthesized) 2477-- Applies to all type entities, true for decimal fixed point 2478-- types and subtypes. 2479 2480-- Is_Descendant_Of_Address (Flag223) 2481-- Defined in all entities. True if the entity is type System.Address, 2482-- or (recursively) a subtype or derived type of System.Address. 2483 2484-- Is_DIC_Procedure (Flag132) 2485-- Defined in functions and procedures. Set for a generated procedure 2486-- which verifies the assumption of pragma Default_Initial_Condition at 2487-- run time. 2488 2489-- Is_Discrete_Or_Fixed_Point_Type (synthesized) 2490-- Applies to all entities, true for all discrete types and subtypes 2491-- and all fixed-point types and subtypes. 2492 2493-- Is_Discrete_Type (synthesized) 2494-- Applies to all entities, true for all discrete types and subtypes 2495 2496-- Is_Discrim_SO_Function (Flag176) 2497-- Defined in all entities. Set only in E_Function entities that Layout 2498-- creates to compute discriminant-dependent dynamic size/offset values. 2499 2500-- Is_Discriminant_Check_Function (Flag264) 2501-- Defined in all entities. Set only in E_Function entities for functions 2502-- created to do discriminant checks. 2503 2504-- Is_Discriminal (synthesized) 2505-- Applies to all entities, true for renamings of discriminants. Such 2506-- entities appear as constants or IN parameters. 2507 2508-- Is_Dispatch_Table_Entity (Flag234) 2509-- Applies to all entities. Set to indicate to the backend that this 2510-- entity is associated with a dispatch table. 2511 2512-- Is_Dispatching_Operation (Flag6) 2513-- Defined in all entities. Set for procedures, functions, generic 2514-- procedures, and generic functions if the corresponding operation 2515-- is dispatching. 2516 2517-- Is_Dynamic_Scope (synthesized) 2518-- Applies to all Entities. Returns True if the entity is a dynamic 2519-- scope (i.e. a block, subprogram, task_type, entry or extended return 2520-- statement). 2521 2522-- Is_Elaboration_Checks_OK_Id (Flag148) 2523-- Defined in elaboration targets (see terminology in Sem_Elab). Set when 2524-- the target appears in a region which is subject to elabled elaboration 2525-- checks. Such targets are allowed to generate run-time conditional ABE 2526-- checks or guaranteed ABE failures. 2527 2528-- Is_Elaboration_Target (synthesized) 2529-- Applies to all entities, True only for elaboration targets (see the 2530-- terminology in Sem_Elab). 2531 2532-- Is_Elaboration_Warnings_OK_Id (Flag304) 2533-- Defined in elaboration targets (see terminology in Sem_Elab). Set when 2534-- the target appears in a region with elaboration warnings enabled. 2535 2536-- Is_Elementary_Type (synthesized) 2537-- Applies to all entities, True for all elementary types and subtypes. 2538-- Either Is_Composite_Type or Is_Elementary_Type (but not both) is true 2539-- of any type. 2540 2541-- Is_Eliminated (Flag124) 2542-- Defined in type entities, subprogram entities, and object entities. 2543-- Indicates that the corresponding entity has been eliminated by use 2544-- of pragma Eliminate. Also used to mark subprogram entities whose 2545-- declaration and body are within unreachable code that is removed. 2546 2547-- Is_Entry (synthesized) 2548-- Applies to all entities, True only for entry and entry family 2549-- entities and False for all other entity kinds. 2550 2551-- Is_Entry_Formal (Flag52) 2552-- Defined in all entities. Set only for entry formals (which can only 2553-- be in, in-out or out parameters). This flag is used to speed up the 2554-- test for the need to replace references in Exp_Ch2. 2555 2556-- Is_Entry_Wrapper (Flag297) 2557-- Defined on wrappers created for entries that have precondition aspects 2558 2559-- Is_Enumeration_Type (synthesized) 2560-- Defined in all entities, true for enumeration types and subtypes 2561 2562-- Is_Exception_Handler (Flag286) 2563-- Defined in blocks. Set if the block serves only as a scope of an 2564-- exception handler with a choice parameter. Such a block does not 2565-- physically appear in the tree. 2566 2567-- Is_Exported (Flag99) 2568-- Defined in all entities. Set if the entity is exported. For now we 2569-- only allow the export of constants, exceptions, functions, procedures 2570-- and variables, but that may well change later on. Exceptions can only 2571-- be exported in the Java VM implementation of GNAT, which is retired. 2572 2573-- Is_External_State (synthesized) 2574-- Applies to all entities, true for abstract states that are subject to 2575-- option External or Synchronous. 2576 2577-- Is_Finalized_Transient (Flag252) 2578-- Defined in constants, loop parameters of generalized iterators, and 2579-- variables. Set when a transient object has been finalized by one of 2580-- the transient finalization mechanisms. The flag prevents the double 2581-- finalization of the object. 2582 2583-- Is_Finalizer (synthesized) 2584-- Applies to all entities, true for procedures containing finalization 2585-- code to process local or library level objects. 2586 2587-- Is_First_Subtype (Flag70) 2588-- Defined in all entities. True for first subtypes (RM 3.2.1(6)), 2589-- i.e. the entity in the type declaration that introduced the type. 2590-- This may be the base type itself (e.g. for record declarations and 2591-- enumeration type declarations), or it may be the first subtype of 2592-- an anonymous base type (e.g. for integer type declarations or 2593-- constrained array declarations). 2594 2595-- Is_Fixed_Point_Type (synthesized) 2596-- Applies to all entities, true for decimal and ordinary fixed 2597-- point types and subtypes. 2598 2599-- Is_Floating_Point_Type (synthesized) 2600-- Applies to all entities, true for float types and subtypes 2601 2602-- Is_Formal (synthesized) 2603-- Applies to all entities, true for IN, IN OUT and OUT parameters 2604 2605-- Is_Formal_Object (synthesized) 2606-- Applies to all entities, true for generic IN and IN OUT parameters 2607 2608-- Is_Formal_Subprogram (Flag111) 2609-- Defined in all entities. Set for generic formal subprograms. 2610 2611-- Is_For_Access_Subtype (Flag118) 2612-- Defined in E_Private_Subtype and E_Record_Subtype entities. Means the 2613-- sole purpose of the type is to be designated by an Access_Subtype and 2614-- hence should not be expanded into components because the type may not 2615-- have been found or frozen yet. 2616 2617-- Is_Frozen (Flag4) 2618-- Defined in all type and subtype entities. Set if type or subtype has 2619-- been frozen. 2620 2621-- Is_Generic_Actual_Subprogram (Flag274) 2622-- Defined on functions and procedures. Set on the entity of the renaming 2623-- declaration created within an instance for an actual subprogram. 2624-- Used to generate constraint checks on calls to these subprograms, even 2625-- within an instance of a predefined run-time unit, in which checks 2626-- are otherwise suppressed. 2627-- 2628-- The flag is also set on the entity of the expression function created 2629-- within an instance, for a function that has external axiomatization, 2630-- for use in GNATprove mode. 2631 2632-- Is_Generic_Actual_Type (Flag94) 2633-- Defined in all type and subtype entities. Set in the subtype 2634-- declaration that renames the generic formal as a subtype of the 2635-- actual. Guarantees that the subtype is not static within the instance. 2636-- Also used during analysis of an instance, to simplify resolution of 2637-- accidental overloading that occurs when different formal types get the 2638-- same actual. 2639 2640-- Is_Generic_Instance (Flag130) 2641-- Defined in all entities. Set to indicate that the entity is an 2642-- instance of a generic unit, or a formal package (which is an instance 2643-- of the template). 2644 2645-- Is_Generic_Subprogram (synthesized) 2646-- Applies to all entities. Yields True for a generic subprogram 2647-- (generic function, generic subprogram), False for all other entities. 2648 2649-- Is_Generic_Type (Flag13) 2650-- Defined in all entities. Set for types which are generic formal types. 2651-- Such types have an Ekind that corresponds to their classification, so 2652-- the Ekind cannot be used to identify generic formal types. 2653 2654-- Is_Generic_Unit (synthesized) 2655-- Applies to all entities. Yields True for a generic unit (generic 2656-- package, generic function, generic procedure), and False for all 2657-- other entities. 2658 2659-- Is_Ghost_Entity (synthesized) 2660-- Applies to all entities. Yields True for abstract states, [generic] 2661-- packages, [generic] subprograms, components, discriminants, formal 2662-- parameters, objects, package bodies, subprogram bodies, and [sub]types 2663-- subject to pragma Ghost or those that inherit the Ghost propery from 2664-- an enclosing construct. 2665 2666-- Is_Hidden (Flag57) 2667-- Defined in all entities. Set for all entities declared in the 2668-- private part or body of a package. Also marks generic formals of a 2669-- formal package declared without a box. For library level entities, 2670-- this flag is set if the entity is not publicly visible. This flag 2671-- is reset when compiling the body of the package where the entity 2672-- is declared, when compiling the private part or body of a public 2673-- child unit, and when compiling a private child unit (see Install_ 2674-- Private_Declaration in sem_ch7). 2675 2676-- Is_Hidden_Non_Overridden_Subpgm (Flag2) 2677-- Defined in all entities. Set for implicitly declared subprograms 2678-- that require overriding or are null procedures, and are hidden by 2679-- a non-fully conformant homograph with the same characteristics 2680-- (Ada RM 8.3 12.3/2). 2681 2682-- Is_Hidden_Open_Scope (Flag171) 2683-- Defined in all entities. Set for a scope that contains the 2684-- instantiation of a child unit, and whose entities are not visible 2685-- during analysis of the instance. 2686 2687-- Is_Ignored_Ghost_Entity (Flag278) 2688-- Applies to all entities. Set for abstract states, [generic] packages, 2689-- [generic] subprograms, components, discriminants, formal parameters, 2690-- objects, package bodies, subprogram bodies, and [sub]types subject to 2691-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2692-- subject to Assertion_Policy Ghost => Ignore. 2693 2694-- Is_Ignored_Transient (Flag295) 2695-- Defined in constants, loop parameters of generalized iterators, and 2696-- variables. Set when a transient object must be processed by one of 2697-- the transient finalization mechanisms. Once marked, a transient is 2698-- intentionally ignored by the general finalization mechanism because 2699-- its clean up actions are context specific. 2700 2701-- Is_Immediately_Visible (Flag7) 2702-- Defined in all entities. Set if entity is immediately visible, i.e. 2703-- is defined in some currently open scope (RM 8.3(4)). 2704 2705-- Is_Implementation_Defined (Flag254) 2706-- Defined in all entities. Set if a pragma Implementation_Defined is 2707-- applied to the pragma. Used to mark all implementation defined 2708-- identifiers in standard library packages, and to implement the 2709-- restriction No_Implementation_Identifiers. 2710 2711-- Is_Imported (Flag24) 2712-- Defined in all entities. Set if the entity is imported. For now we 2713-- only allow the import of exceptions, functions, procedures, packages, 2714-- constants, and variables. Exceptions, packages, and types can only be 2715-- imported in the Java VM implementation, which is retired. 2716 2717-- Is_Incomplete_Or_Private_Type (synthesized) 2718-- Applies to all entities, true for private and incomplete types 2719 2720-- Is_Incomplete_Type (synthesized) 2721-- Applies to all entities, true for incomplete types and subtypes 2722 2723-- Is_Independent (Flag268) 2724-- Defined in all type entities, and also in constants, components and 2725-- variables. Set if a valid pragma or aspect Independent applies to the 2726-- entity, or if a valid pragma or aspect Independent_Components applies 2727-- to the enclosing record type for a component. Also set if a pragma 2728-- Shared or pragma Atomic applies to the entity. In the case of private 2729-- and incomplete types, this flag is set in both the partial view and 2730-- the full view. 2731 2732-- Is_Initial_Condition_Procedure (Flag302) 2733-- Defined in functions and procedures. Set for a generated procedure 2734-- which verifies the assumption of pragma Initial_Condition at run time. 2735 2736-- Is_Inlined (Flag11) 2737-- Defined in all entities. Set for functions and procedures which are 2738-- to be inlined. For subprograms created during expansion, this flag 2739-- may be set directly by the expander to request inlining. Also set 2740-- for packages that contain inlined subprograms, whose bodies must be 2741-- be compiled. Is_Inlined is also set on generic subprograms and is 2742-- inherited by their instances. It is also set on the body entities 2743-- of inlined subprograms. See also Has_Pragma_Inline. 2744 2745-- Is_Inlined_Always (Flag1) 2746-- Defined in subprograms. Set for functions and procedures which are 2747-- always inlined in GNATprove mode. GNATprove uses this flag to know 2748-- when a body does not need to be analyzed. The value of this flag is 2749-- only meaningful if Body_To_Inline is not Empty for the subprogram. 2750 2751-- Is_Instantiated (Flag126) 2752-- Defined in generic packages and generic subprograms. Set if the unit 2753-- is instantiated from somewhere in the extended main source unit. This 2754-- flag is used to control warnings about the unit being uninstantiated. 2755-- Also set in a package that is used as an actual for a generic package 2756-- formal in an instantiation. Also set on a parent instance, in the 2757-- instantiation of a child, which is implicitly declared in the parent. 2758 2759-- Is_Integer_Type (synthesized) 2760-- Applies to all entities, true for integer types and subtypes 2761 2762-- Is_Interface (Flag186) 2763-- Defined in record types and subtypes. Set to indicate that the current 2764-- entity corresponds to an abstract interface. Because abstract 2765-- interfaces are conceptually a special kind of abstract tagged type 2766-- we represent them by means of tagged record types and subtypes 2767-- marked with this attribute. This allows us to reuse most of the 2768-- compiler support for abstract tagged types to implement interfaces 2769-- (Ada 2005: AI-251). 2770 2771-- Is_Internal (Flag17) 2772-- Defined in all entities. Set to indicate an entity created during 2773-- semantic processing (e.g. an implicit type, or a temporary). The 2774-- current uses of this flag are: 2775-- 2776-- 1) Internal entities (such as temporaries generated for the result 2777-- of an inlined function call or dummy variables generated for the 2778-- debugger). Set to indicate that they need not be initialized, even 2779-- when scalars are initialized or normalized. 2780-- 2781-- 2) Predefined primitives of tagged types. Set to mark that they 2782-- have specific properties: first they are primitives even if they 2783-- are not defined in the type scope (the freezing point is not 2784-- necessarily in the same scope), and second the predefined equality 2785-- can be overridden by a user-defined equality, no body will be 2786-- generated in this case. 2787-- 2788-- 3) Object declarations generated by the expander that are implicitly 2789-- imported or exported so that they can be marked in Sprint output. 2790-- 2791-- 4) Internal entities in the list of primitives of tagged types that 2792-- are used to handle secondary dispatch tables. These entities have 2793-- also the attribute Interface_Alias. 2794 2795-- Is_Interrupt_Handler (Flag89) 2796-- Defined in procedures. Set if a pragma Interrupt_Handler applies 2797-- to the procedure. The procedure must be parameterless, and on all 2798-- targets except AAMP it must be a protected procedure. 2799 2800-- Is_Intrinsic_Subprogram (Flag64) 2801-- Defined in functions and procedures. It is set if a valid pragma 2802-- Interface or Import is present for this subprogram specifying 2803-- convention Intrinsic. Valid means that the name and profile of the 2804-- subprogram match the requirements of one of the recognized intrinsic 2805-- subprograms (see package Sem_Intr for details). Note: the value of 2806-- Convention for such an entity will be set to Convention_Intrinsic, 2807-- but it is the setting of Is_Intrinsic_Subprogram, NOT simply having 2808-- convention set to intrinsic, which causes intrinsic code to be 2809-- generated. 2810 2811-- Is_Invariant_Procedure (Flag257) 2812-- Defined in functions and procedures. Set for a generated invariant 2813-- procedure which verifies the invariants of both the partial and full 2814-- views of a private type or private extension as well as any inherited 2815-- class-wide invariants from parent types or interfaces. 2816 2817-- Is_Itype (Flag91) 2818-- Defined in all entities. Set to indicate that a type is an Itype, 2819-- which means that the declaration for the type does not appear 2820-- explicitly in the tree. Instead the backend will elaborate the type 2821-- when it is first used. Has_Delayed_Freeze can be set for Itypes, and 2822-- the meaning is that the first use (the one which causes the type to be 2823-- defined) will be the freeze node. Note that an important restriction 2824-- on Itypes is that the first use of such a type (the one that causes it 2825-- to be defined) must be in the same scope as the type. 2826 2827-- Is_Known_Non_Null (Flag37) 2828-- Defined in all entities. Relevant (and can be set) only for 2829-- objects of an access type. It is set if the object is currently 2830-- known to have a non-null value (meaning that no access checks 2831-- are needed). The indication can for example come from assignment 2832-- of an access parameter or an allocator whose value is known non-null. 2833-- 2834-- Note: this flag is set according to the sequential flow of the 2835-- program, watching the current value of the variable. However, this 2836-- processing can miss cases of changing the value of an aliased or 2837-- constant object, so even if this flag is set, it should not be 2838-- believed if the variable is aliased or volatile. It would be a 2839-- little neater to avoid the flag being set in the first place in 2840-- such cases, but that's trickier, and there is only one place that 2841-- tests the value anyway. 2842-- 2843-- The flag is dynamically set and reset as semantic analysis and 2844-- expansion proceeds. Its value is meaningless once the tree is 2845-- fully constructed, since it simply indicates the last state. 2846-- Thus this flag has no meaning to the backend. 2847 2848-- Is_Known_Null (Flag204) 2849-- Defined in all entities. Relevant (and can be set ) only for 2850-- objects of an access type. It is set if the object is currently known 2851-- to have a null value (meaning that a dereference will surely raise 2852-- constraint error exception). The indication can come from an 2853-- assignment or object declaration. 2854-- 2855-- The comments above about sequential flow and aliased and volatile for 2856-- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag. 2857 2858-- Is_Known_Valid (Flag170) 2859-- Defined in all entities. Relevant for types (and subtype) and 2860-- for objects (and enumeration literals) of a discrete type. 2861-- 2862-- The purpose of this flag is to implement the requirement stated 2863-- in (RM 13.9.1(9-11)) which require that the use of possibly invalid 2864-- values may not cause programs to become erroneous. See the function 2865-- Checks.Expr_Known_Valid for further details. Note that the setting 2866-- is conservative, in the sense that if the flag is set, it must be 2867-- right. If the flag is not set, nothing is known about the validity. 2868-- 2869-- For enumeration literals, the flag is always set, since clearly 2870-- an enumeration literal represents a valid value. Range checks 2871-- where necessary will ensure that this valid value is appropriate. 2872-- 2873-- For objects, the flag indicates the state of knowledge about the 2874-- current value of the object. This may be modified during expansion, 2875-- and thus the final value is not relevant to the backend. 2876-- 2877-- For types and subtypes, the flag is set if all possible bit patterns 2878-- of length Object_Size (i.e. Esize of the type) represent valid values 2879-- of the type. In general for such types, all values are valid, the 2880-- only exception being the case where an object of the type has an 2881-- explicit size that is greater than Object_Size. 2882-- 2883-- For non-discrete objects, the setting of the Is_Known_Valid flag is 2884-- not defined, and is not relevant, since the considerations of the 2885-- requirement in (RM 13.9.1(9-11)) do not apply. 2886-- 2887-- The flag is dynamically set and reset as semantic analysis and 2888-- expansion proceeds. Its value is meaningless once the tree is 2889-- fully constructed, since it simply indicates the last state. 2890-- Thus this flag has no meaning to the backend. 2891 2892-- Is_Limited_Composite (Flag106) 2893-- Defined in all entities. Set for composite types that have a limited 2894-- component. Used to enforce the rule that operations on the composite 2895-- type that depend on the full view of the component do not become 2896-- visible until the immediate scope of the composite type itself 2897-- (RM 7.3.1 (5)). 2898 2899-- Is_Limited_Interface (Flag197) 2900-- Defined in record types and subtypes. True for interface types, if 2901-- interface is declared limited, task, protected, or synchronized, or 2902-- is derived from a limited interface. 2903 2904-- Is_Limited_Record (Flag25) 2905-- Defined in all entities. Set to true for record (sub)types if the 2906-- record is declared to be limited. Note that this flag is not set 2907-- simply because some components of the record are limited. 2908 2909-- Is_Local_Anonymous_Access (Flag194) 2910-- Defined in access types. Set for an anonymous access type to indicate 2911-- that the type is created for a record component with an access 2912-- definition, an array component, or (pre-Ada 2012) a standalone object. 2913-- Such anonymous types have an accessibility level equal to that of the 2914-- declaration in which they appear, unlike the anonymous access types 2915-- that are created for access parameters, access discriminants, and 2916-- (as of Ada 2012) stand-alone objects. 2917 2918-- Is_Loop_Parameter (Flag307) 2919-- Applies to all entities. Certain loops, in particular "for ... of" 2920-- loops, get transformed so that the loop parameter is declared by a 2921-- variable declaration, so the entity is an E_Variable. This is True for 2922-- such E_Variables; False otherwise. 2923 2924-- Is_Machine_Code_Subprogram (Flag137) 2925-- Defined in subprogram entities. Set to indicate that the subprogram 2926-- is a machine code subprogram (i.e. its body includes at least one 2927-- code statement). Also indicates that all necessary semantic checks 2928-- as required by RM 13.8(3) have been performed. 2929 2930-- Is_Modular_Integer_Type (synthesized) 2931-- Applies to all entities. True if entity is a modular integer type 2932 2933-- Is_Non_Static_Subtype (Flag109) 2934-- Defined in all type and subtype entities. It is set in some (but not 2935-- all) cases in which a subtype is known to be non-static. Before this 2936-- flag was added, the computation of whether a subtype was static was 2937-- entirely synthesized, by looking at the bounds, and the immediate 2938-- subtype parent. However, this method does not work for some Itypes 2939-- that have no parent set (and the only way to find the immediate 2940-- subtype parent is to go through the tree). For now, this flag is set 2941-- conservatively, i.e. if it is set then for sure the subtype is non- 2942-- static, but if it is not set, then the type may or may not be static. 2943-- Thus the test for a static subtype is that this flag is clear AND that 2944-- the bounds are static AND that the parent subtype (if available to be 2945-- tested) is static. Eventually we should make sure this flag is always 2946-- set right, at which point, these comments can be removed, and the 2947-- tests for static subtypes greatly simplified. 2948 2949-- Is_Null_Init_Proc (Flag178) 2950-- Defined in procedure entities. Set for generated init proc procedures 2951-- (used to initialize composite types), if the code for the procedure 2952-- is null (i.e. is a return and nothing else). Such null initialization 2953-- procedures are generated in case some client is compiled using the 2954-- Initialize_Scalars pragma, generating a call to this null procedure, 2955-- but there is no need to call such procedures within a compilation 2956-- unit, and this flag is used to suppress such calls. 2957 2958-- Is_Null_State (synthesized) 2959-- Applies to all entities, true for an abstract state declared with 2960-- keyword null. 2961 2962-- Is_Numeric_Type (synthesized) 2963-- Applies to all entities, true for all numeric types and subtypes 2964-- (integer, fixed, float). 2965 2966-- Is_Object (synthesized) 2967-- Applies to all entities, true for entities representing objects, 2968-- including generic formal parameters. 2969 2970-- Is_Obsolescent (Flag153) 2971-- Defined in all entities. Set for any entity to which a valid pragma 2972-- or aspect Obsolescent applies. 2973 2974-- Is_Only_Out_Parameter (Flag226) 2975-- Defined in formal parameter entities. Set if this parameter is the 2976-- only OUT parameter for this formal part. If there is more than one 2977-- out parameter, or if there is some other IN OUT parameter then this 2978-- flag is not set in any of them. Used in generation of warnings. 2979 2980-- Is_Ordinary_Fixed_Point_Type (synthesized) 2981-- Applies to all entities, true for ordinary fixed point types and 2982-- subtypes. 2983 2984-- Is_Package_Body_Entity (Flag160) 2985-- Defined in all entities. Set for entities defined at the top level 2986-- of a package body. Used to control externally generated names. 2987 2988-- Is_Package_Or_Generic_Package (synthesized) 2989-- Applies to all entities. True for packages and generic packages. 2990-- False for all other entities. 2991 2992-- Is_Packed (Flag51) [implementation base type only] 2993-- Defined in all type entities. This flag is set only for record and 2994-- array types which have a packed representation. There are four cases 2995-- which cause packing: 2996-- 2997-- 1. Explicit use of pragma Pack to pack a record. 2998-- 2. Explicit use of pragma Pack to pack an array. 2999-- 3. Setting Component_Size of an array to a packable value. 3000-- 4. Indexing an array with a non-standard enumeration type. 3001-- 3002-- For records, Is_Packed is always set if Has_Pragma_Pack is set, and 3003-- can also be set on its own in a derived type which inherited its 3004-- packed status. 3005-- 3006-- For arrays, Is_Packed is set if either Has_Pragma_Pack is set and the 3007-- component size is either not known at compile time or known but not 3008-- 8/16/32/64 bits, or a Component_Size clause exists and the specified 3009-- value is smaller than 64 bits but not 8/16/32, or if the array has one 3010-- or more index types that are enumeration types with a non-standard 3011-- representation (in GNAT, we store such arrays compactly, using the Pos 3012-- of the enumeration type value). As for the case of records, Is_Packed 3013-- can be set on its own for a derived type. 3014 3015-- Before an array type is frozen, Is_Packed will always be set if 3016-- Has_Pragma_Pack is set. Before the freeze point, it is not possible 3017-- to know the component size, since the component type is not frozen 3018-- until the array type is frozen. Thus Is_Packed for an array type 3019-- before it is frozen means that packed is required. Then if it turns 3020-- out that the component size doesn't require packing, the Is_Packed 3021-- flag gets turned off. 3022 3023-- In the bit-packed array case (i.e. the component size is known by the 3024-- front end and is in the range 1-63 but not a multiple of 8), then the 3025-- Is_Bit_Packed_Array flag will be set once the array type is frozen. 3026-- 3027-- Is_Packed_Array (synth) 3028-- Applies to all entities, true if entity is for a packed array. 3029 3030-- Is_Packed_Array_Impl_Type (Flag138) 3031-- Defined in all entities. This flag is set on the entity for the type 3032-- used to implement a packed array (either a modular type or a subtype 3033-- of Packed_Bytes{1,2,4} in the bit-packed array case, a regular array 3034-- in the non-standard enumeration index case). It is set if and only 3035-- if the type appears in the Packed_Array_Impl_Type field of some other 3036-- entity. It is used by the back end to activate the special processing 3037-- for such types (unchecked conversions that would not otherwise be 3038-- allowed are allowed for such types). If Is_Packed_Array_Impl_Type is 3039-- set in an entity, then the Original_Array_Type field of this entity 3040-- points to the array type for which this is the Packed_Array_Impl_Type. 3041 3042-- Is_Param_Block_Component_Type (Flag215) [base type only] 3043-- Defined in access types. Set to indicate that a type is the type of a 3044-- component of the parameter block record type generated by the compiler 3045-- for an entry or a select statement. Read by CodePeer. 3046 3047-- Is_Partial_Invariant_Procedure (Flag292) 3048-- Defined in functions and procedures. Set for a generated invariant 3049-- procedure which verifies the invariants of the partial view of a 3050-- private type or private extension. 3051 3052-- Is_Potentially_Use_Visible (Flag9) 3053-- Defined in all entities. Set if entity is potentially use visible, 3054-- i.e. it is defined in a package that appears in a currently active 3055-- use clause (RM 8.4(8)). Note that potentially use visible entities 3056-- are not necessarily use visible (RM 8.4(9-11)). 3057 3058-- Is_Predicate_Function (Flag255) 3059-- Present in functions and procedures. Set for generated predicate 3060-- functions. 3061 3062-- Is_Predicate_Function_M (Flag256) 3063-- Present in functions and procedures. Set for special version of 3064-- predicate function generated for use in membership tests, where 3065-- raise expressions are transformed to return False. 3066 3067-- Is_Preelaborated (Flag59) 3068-- Defined in all entities, set in E_Package and E_Generic_Package 3069-- entities to which a pragma Preelaborate is applied, and also in 3070-- all entities within such packages. Note that the fact that this 3071-- flag is set does not necesarily mean that no elaboration code is 3072-- generated for the package. 3073 3074-- Is_Primitive (Flag218) 3075-- Defined in overloadable entities and in generic subprograms. Set to 3076-- indicate that this is a primitive operation of some type, which may 3077-- be a tagged type or an untagged type. Used to verify overriding 3078-- indicators in bodies. 3079 3080-- Is_Primitive_Wrapper (Flag195) 3081-- Defined in functions and procedures created by the expander to serve 3082-- as an indirection mechanism to overriding primitives of concurrent 3083-- types, entries and protected procedures. 3084 3085-- Is_Prival (synthesized) 3086-- Applies to all entities, true for renamings of private protected 3087-- components. Such entities appear as constants or variables. 3088 3089-- Is_Private_Composite (Flag107) 3090-- Defined in composite types that have a private component. Used to 3091-- enforce the rule that operations on the composite type that depend 3092-- on the full view of the component, do not become visible until the 3093-- immediate scope of the composite type itself (7.3.1 (5)). Both this 3094-- flag and Is_Limited_Composite are needed. 3095 3096-- Is_Private_Descendant (Flag53) 3097-- Defined in entities that can represent library units (packages, 3098-- functions, procedures). Set if the library unit is itself a private 3099-- child unit, or if it is the descendant of a private child unit. 3100 3101-- Is_Private_Primitive (Flag245) 3102-- Defined in subprograms. Set if the operation is a primitive of a 3103-- tagged type (procedure or function dispatching on result) whose 3104-- full view has not been seen. Used in particular for primitive 3105-- subprograms of a synchronized type declared between the two views 3106-- of the type, so that the wrapper built for such a subprogram can 3107-- be given the proper signature. 3108 3109-- Is_Private_Type (synthesized) 3110-- Applies to all entities, true for private types and subtypes, 3111-- as well as for record with private types as subtypes. 3112 3113-- Is_Protected_Component (synthesized) 3114-- Applicable to all entities, true if the entity denotes a private 3115-- component of a protected type. 3116 3117-- Is_Protected_Interface (synthesized) 3118-- Defined in types that are interfaces. True if interface is declared 3119-- protected, or is derived from protected interfaces. 3120 3121-- Is_Protected_Record_Type (synthesized) 3122-- Applies to all entities, true if Is_Concurrent_Record_Type is true and 3123-- Corresponding_Concurrent_Type is a protected type. 3124 3125-- Is_Protected_Type (synthesized) 3126-- Applies to all entities, true for protected types and subtypes 3127 3128-- Is_Public (Flag10) 3129-- Defined in all entities. Set to indicate that an entity defined in 3130-- one compilation unit can be referenced from other compilation units. 3131-- If this reference causes a reference in the generated code, for 3132-- example in the case of a variable name, then the backend will generate 3133-- an appropriate external name for use by the linker. 3134 3135-- Is_Pure (Flag44) 3136-- Defined in all entities. Set in all entities of a unit to which a 3137-- pragma Pure is applied except for non-intrinsic imported subprograms, 3138-- and also set for the entity of the unit itself. In addition, this 3139-- flag may be set for any other functions or procedures that are known 3140-- to be side effect free, so in the case of subprograms, the Is_Pure 3141-- flag may be used by the optimizer to imply that it can assume freedom 3142-- from side effects (other than those resulting from assignment to Out 3143-- or In Out parameters, or to objects designated by access parameters). 3144 3145-- Is_Pure_Unit_Access_Type (Flag189) 3146-- Defined in access type and subtype entities. Set if the type or 3147-- subtype appears in a pure unit. Used to give an error message at 3148-- freeze time if the access type has a storage pool. 3149 3150-- Is_RACW_Stub_Type (Flag244) 3151-- Defined in all types, true for the stub types generated for remote 3152-- access-to-class-wide types. 3153 3154-- Is_Raised (Flag224) 3155-- Defined in exception entities. Set if the entity is referenced by a 3156-- a raise statement. 3157 3158-- Is_Real_Type (synthesized) 3159-- Applies to all entities, true for real types and subtypes 3160 3161-- Is_Record_Type (synthesized) 3162-- Applies to all entities, true for record types and subtypes, 3163-- includes class-wide types and subtypes (which are also records). 3164 3165-- Is_Remote_Call_Interface (Flag62) 3166-- Defined in all entities. Set in E_Package and E_Generic_Package 3167-- entities to which a pragma Remote_Call_Interface is applied, and 3168-- also on entities declared in the visible part of such a package. 3169 3170-- Is_Remote_Types (Flag61) 3171-- Defined in all entities. Set in E_Package and E_Generic_Package 3172-- entities to which a pragma Remote_Types is applied, and also on 3173-- entities declared in the visible part of the spec of such a package. 3174-- Also set for types which are generic formal types to which the 3175-- pragma Remote_Access_Type applies. 3176 3177-- Is_Renaming_Of_Object (Flag112) 3178-- Defined in all entities, set only for a variable or constant for 3179-- which the Renamed_Object field is non-empty and for which the 3180-- renaming is handled by the front end, by macro substitution of 3181-- a copy of the (evaluated) name tree whereever the variable is used. 3182 3183-- Is_Return_Object (Flag209) 3184-- Defined in all object entities. True if the object is the return 3185-- object of an extended_return_statement; False otherwise. 3186 3187-- Is_Safe_To_Reevaluate (Flag249) 3188-- Defined in all entities. Set in variables that are initialized by 3189-- means of an assignment statement. When initialized their contents 3190-- never change and hence they can be seen by the backend as constants. 3191-- See also Is_True_Constant. 3192 3193-- Is_Scalar_Type (synthesized) 3194-- Applies to all entities, true for scalar types and subtypes 3195 3196-- Is_Shared_Passive (Flag60) 3197-- Defined in all entities. Set in E_Package and E_Generic_Package 3198-- entities to which a pragma Shared_Passive is applied, and also in 3199-- all entities within such packages. 3200 3201-- Is_Standard_Character_Type (synthesized) 3202-- Applies to all entities, true for types and subtypes whose root type 3203-- is one of the standard character types (Character, Wide_Character, or 3204-- Wide_Wide_Character). 3205 3206-- Is_Standard_String_Type (synthesized) 3207-- Applies to all entities, true for types and subtypes whose root 3208-- type is one of the standard string types (String, Wide_String, or 3209-- Wide_Wide_String). 3210 3211-- Is_Static_Type (Flag281) 3212-- Defined in entities. Only set for (sub)types. If set, indicates that 3213-- the type is known to be a static type (defined as a discrete type with 3214-- static bounds, a record all of whose component types are static types, 3215-- or an array, all of whose bounds are of a static type, and also have 3216-- a component type that is a static type). See Set_Uplevel_Type for more 3217-- information on how this flag is used. 3218 3219-- Is_Statically_Allocated (Flag28) 3220-- Defined in all entities. This can only be set for exception, 3221-- variable, constant, and type/subtype entities. If the flag is set, 3222-- then the variable or constant must be allocated statically rather 3223-- than on the local stack frame. For exceptions, the meaning is that 3224-- the exception data should be allocated statically (and indeed this 3225-- flag is always set for exceptions, since exceptions do not have 3226-- local scope). For a type, the meaning is that the type must be 3227-- elaborated at the global level rather than locally. No type marked 3228-- with this flag may depend on a local variable, or on any other type 3229-- which does not also have this flag set to True. For a variable or 3230-- or constant, if the flag is set, then the type of the object must 3231-- either be declared at the library level, or it must also have the 3232-- flag set (since to allocate the object statically, its type must 3233-- also be elaborated globally). 3234 3235-- Is_String_Type (synthesized) 3236-- Applies to all type entities. Determines if the given type is a 3237-- string type, i.e. it is directly a string type or string subtype, 3238-- or a string slice type, or an array type with one dimension and a 3239-- component type that is a character type. 3240 3241-- Is_Subprogram (synthesized) 3242-- Applies to all entities, true for function, procedure and operator 3243-- entities. 3244 3245-- Is_Subprogram_Or_Generic_Subprogram 3246-- Applies to all entities, true for function procedure and operator 3247-- entities, and also for the corresponding generic entities. 3248 3249-- Is_Synchronized_Interface (synthesized) 3250-- Defined in types that are interfaces. True if interface is declared 3251-- synchronized, task, or protected, or is derived from a synchronized 3252-- interface. 3253 3254-- Is_Synchronized_State (synthesized) 3255-- Applies to all entities, true for abstract states that are subject to 3256-- option Synchronous. 3257 3258-- Is_Tag (Flag78) 3259-- Defined in E_Component and E_Constant entities. For regular tagged 3260-- type this flag is set on the tag component (whose name is Name_uTag). 3261-- For CPP_Class tagged types, this flag marks the pointer to the main 3262-- vtable (i.e. the one to be extended by derivation). 3263 3264-- Is_Tagged_Type (Flag55) 3265-- Defined in all entities, set for an entity that is a tagged type 3266 3267-- Is_Task_Interface (synthesized) 3268-- Defined in types that are interfaces. True if interface is declared as 3269-- a task interface, or if it is derived from task interfaces. 3270 3271-- Is_Task_Record_Type (synthesized) 3272-- Applies to all entities, true if Is_Concurrent_Record_Type is true and 3273-- Corresponding_Concurrent_Type is a task type. 3274 3275-- Is_Task_Type (synthesized) 3276-- Applies to all entities. True for task types and subtypes 3277 3278-- Is_Thunk (Flag225) 3279-- Defined in all entities. True for subprograms that are thunks: that is 3280-- small subprograms built by the expander for tagged types that cover 3281-- interface types. As part of the runtime call to an interface, thunks 3282-- displace the pointer to the object (pointer named "this" in the C++ 3283-- terminology) from a secondary dispatch table to the primary dispatch 3284-- table associated with a given tagged type; if the thunk is a function 3285-- that returns an object which covers an interface type then the thunk 3286-- displaces the pointer to the object from the primary dispatch table to 3287-- the secondary dispatch table associated with the interface type. Set 3288-- by Expand_Interface_Thunk and used by Expand_Call to handle extra 3289-- actuals associated with accessibility level. 3290 3291-- Is_Trivial_Subprogram (Flag235) 3292-- Defined in all entities. Set in subprograms where either the body 3293-- consists of a single null statement, or the first or only statement 3294-- of the body raises an exception. This is used for suppressing certain 3295-- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details. 3296 3297-- Is_True_Constant (Flag163) 3298-- Defined in all entities for constants and variables. Set in constants 3299-- and variables which have an initial value specified but which are 3300-- never assigned, partially or in the whole. For variables, it means 3301-- that the variable was initialized but never modified, and hence can be 3302-- treated as a constant by the code generator. For a constant, it means 3303-- that the constant was not modified by generated code (e.g. to set a 3304-- discriminant in an init proc). Assignments by user or generated code 3305-- will reset this flag. See also Is_Safe_To_Reevaluate. 3306 3307-- Is_Type (synthesized) 3308-- Applies to all entities, true for a type entity 3309 3310-- Is_Unchecked_Union (Flag117) [implementation base type only] 3311-- Defined in all entities. Set only in record types to which the 3312-- pragma Unchecked_Union has been validly applied. 3313 3314-- Is_Underlying_Full_View (Flag298) 3315-- Defined in all entities. Set for types which represent the true full 3316-- view of a private type completed by another private type. For further 3317-- details, see attribute Underlying_Full_View. 3318 3319-- Is_Underlying_Record_View (Flag246) [base type only] 3320-- Defined in all entities. Set only in record types that represent the 3321-- underlying record view. This view is built for derivations of types 3322-- with unknown discriminants; it is a record with the same structure 3323-- as its corresponding record type, but whose parent is the full view 3324-- of the parent in the original type extension. 3325 3326-- Is_Unimplemented (Flag284) 3327-- Defined in all entities. Set for any entity to which a valid pragma 3328-- or aspect Unimplemented applies. 3329 3330-- Is_Unsigned_Type (Flag144) 3331-- Defined in all types, but can be set only for discrete and fixed-point 3332-- type and subtype entities. This flag is only valid if the entity is 3333-- frozen. If set it indicates that the representation is known to be 3334-- unsigned (i.e. that no negative values appear in the range). This is 3335-- normally just a reflection of the lower bound of the subtype or base 3336-- type, but there is one case in which the setting is non-obvious, 3337-- namely the case of an unsigned subtype of a signed type from which 3338-- a further subtype is obtained using variable bounds. This further 3339-- subtype is still unsigned, but this cannot be determined by looking 3340-- at its bounds or the bounds of the corresponding base type. 3341-- For a subtype indication whose range is statically a null range, 3342-- the flag is set if the lower bound is non-negative, but the flag 3343-- cannot be used to determine the comparison operator to emit in the 3344-- generated code: use the base type. 3345 3346-- Is_Uplevel_Referenced_Entity (Flag283) 3347-- Defined in all entities. Used when unnesting subprograms to indicate 3348-- that an entity is locally defined within a subprogram P, and there is 3349-- a reference to the entity within a subprogram nested within P (at any 3350-- depth). Set for uplevel referenced objects (variables, constants, 3351-- discriminants and loop parameters), and also for upreferenced dynamic 3352-- types, including the cases where the reference is implicit (e.g. the 3353-- type of an array used for computing the location of an element in an 3354-- array. This is used internally in Exp_Unst, see this package for 3355-- further details. 3356 3357-- Is_Valued_Procedure (Flag127) 3358-- Defined in procedure entities. Set if an Import_Valued_Procedure 3359-- or Export_Valued_Procedure pragma applies to the procedure entity. 3360 3361-- Is_Visible_Formal (Flag206) 3362-- Defined in all entities. Set for instances of the formals of a 3363-- formal package. Indicates that the entity must be made visible in the 3364-- body of the instance, to reproduce the visibility of the generic. 3365-- This simplifies visibility settings in instance bodies. 3366 3367-- Is_Visible_Lib_Unit (Flag116) 3368-- Defined in all (root or child) library unit entities. Once compiled, 3369-- library units remain chained to the entities in the parent scope, and 3370-- a separate flag must be used to indicate whether the names are visible 3371-- by selected notation, or not. 3372 3373-- Is_Volatile (Flag16) 3374-- Defined in all type entities, and also in constants, components and 3375-- variables. Set if a pragma Volatile applies to the entity. Also set 3376-- if pragma Shared or pragma Atomic applies to entity. In the case of 3377-- private or incomplete types, this flag is set in both the private 3378-- and full view. The flag is not set reliably on private subtypes, 3379-- and is always retrieved from the base type (but this is not a base- 3380-- type-only attribute because it applies to other entities). Note that 3381-- the backend should use Treat_As_Volatile, rather than Is_Volatile 3382-- to indicate code generation requirements for volatile variables. 3383-- Similarly, any front end test which is concerned with suppressing 3384-- optimizations on volatile objects should test Treat_As_Volatile 3385-- rather than testing this flag. 3386 3387-- Is_Volatile_Full_Access (Flag285) 3388-- Defined in all type entities, and also in constants, components, and 3389-- variables. Set if a pragma Volatile_Full_Access applies to the entity. 3390-- In the case of private and incomplete types, this flag is set in 3391-- both the partial view and the full view. 3392 3393-- Is_Wrapper_Package (synthesized) 3394-- Defined in package entities. Indicates that the package has been 3395-- created as a wrapper for a subprogram instantiation. 3396 3397-- Itype_Printed (Flag202) 3398-- Defined in all type and subtype entities. Set in Itypes if the Itype 3399-- has been printed by Sprint. This is used to avoid printing an Itype 3400-- more than once. 3401 3402-- Kill_Elaboration_Checks (Flag32) 3403-- Defined in all entities. Set by the expander to kill elaboration 3404-- checks which are known not to be needed. Equivalent in effect to 3405-- the use of pragma Suppress (Elaboration_Checks) for that entity 3406-- except that the effect is permanent and cannot be undone by a 3407-- subsequent pragma Unsuppress. 3408 3409-- Kill_Range_Checks (Flag33) 3410-- Defined in all entities. Equivalent in effect to the use of pragma 3411-- Suppress (Range_Checks) for that entity except that the result is 3412-- permanent and cannot be undone by a subsequent pragma Unsuppress. 3413-- This is currently only used in one odd situation in Sem_Ch3 for 3414-- record types, and it would be good to get rid of it??? 3415 3416-- Known_To_Have_Preelab_Init (Flag207) 3417-- Defined in all type and subtype entities. If set, then the type is 3418-- known to have preelaborable initialization. In the case of a partial 3419-- view of a private type, it is only possible for this to be set if a 3420-- pragma Preelaborable_Initialization is given for the type. For other 3421-- types, it is never set if the type does not have preelaborable 3422-- initialization, it may or may not be set if the type does have 3423-- preelaborable initialization. 3424 3425-- Last_Aggregate_Assignment (Node30) 3426-- Applies to controlled constants and variables initialized by an 3427-- aggregate. Points to the last statement associated with the expansion 3428-- of the aggregate. The attribute is used by the finalization machinery 3429-- when marking an object as successfully initialized. 3430 3431-- Last_Assignment (Node26) 3432-- Defined in entities for variables, and OUT or IN OUT formals. Set for 3433-- a local variable or formal to point to the left side of an assignment 3434-- statement assigning a value to the variable. Cleared if the value of 3435-- the entity is referenced. Used to warn about dubious assignment 3436-- statements whose value is not used. 3437 3438-- Last_Entity (Node20) 3439-- Defined in all entities which act as scopes to which a list of 3440-- associated entities is attached (blocks, class subtypes and types, 3441-- entries, functions, loops, packages, procedures, protected objects, 3442-- record types and subtypes, private types, task types and subtypes). 3443-- Points to the last entry in the list of associated entities chained 3444-- through the Next_Entity field. Empty if no entities are chained. 3445 3446-- Last_Formal (synthesized) 3447-- Applies to subprograms and subprogram types, and also in entries 3448-- and entry families. Returns last formal of the subprogram or entry. 3449-- The formals are the first entities declared in a subprogram or in 3450-- a subprogram type (the designated type of an Access_To_Subprogram 3451-- definition) or in an entry. 3452 3453-- Limited_View (Node23) 3454-- Defined in non-generic package entities that are not instances. Bona 3455-- fide package with the limited-view list through the first_entity and 3456-- first_private attributes. The elements of this list are the shadow 3457-- entities created for the types and local packages that are declared 3458-- in a package appearing in a limited_with clause (Ada 2005: AI-50217). 3459 3460-- Linker_Section_Pragma (Node33) 3461-- Present in constant, variable, type and subprogram entities. Points 3462-- to a linker section pragma that applies to the entity, or is Empty if 3463-- no such pragma applies. Note that for constants and variables, this 3464-- field may be set as a result of a linker section pragma applied to the 3465-- type of the object. 3466 3467-- Lit_Indexes (Node18) 3468-- Defined in enumeration types and subtypes. Non-empty only for the 3469-- case of an enumeration root type, where it contains the entity for 3470-- the generated indexes entity. See unit Exp_Imgv for full details of 3471-- the nature and use of this entity for implementing the Image and 3472-- Value attributes for the enumeration type in question. 3473 3474-- Lit_Strings (Node16) 3475-- Defined in enumeration types and subtypes. Non-empty only for the 3476-- case of an enumeration root type, where it contains the entity for 3477-- the literals string entity. See unit Exp_Imgv for full details of 3478-- the nature and use of this entity for implementing the Image and 3479-- Value attributes for the enumeration type in question. 3480 3481-- Low_Bound_Tested (Flag205) 3482-- Defined in all entities. Currently this can only be set for formal 3483-- parameter entries of a standard unconstrained one-dimensional array 3484-- or string type. Indicates that an explicit test of the low bound of 3485-- the formal appeared in the code, e.g. in a pragma Assert. If this 3486-- flag is set, warnings about assuming the index low bound to be one 3487-- are suppressed. 3488 3489-- Machine_Radix_10 (Flag84) 3490-- Defined in decimal types and subtypes, set if the Machine_Radix is 10, 3491-- as the result of the specification of a machine radix representation 3492-- clause. Note that it is possible for this flag to be set without 3493-- having Has_Machine_Radix_Clause True. This happens when a type is 3494-- derived from a type with a clause present. 3495 3496-- Master_Id (Node17) 3497-- Defined in access types and subtypes. Empty unless Has_Task is set for 3498-- the designated type, in which case it points to the entity for the 3499-- Master_Id for the access type master. Also set for access-to-limited- 3500-- class-wide types whose root may be extended with task components, and 3501-- for access-to-limited-interfaces because they can be used to reference 3502-- tasks implementing such interface. 3503 3504-- Materialize_Entity (Flag168) 3505-- Defined in all entities. Set only for renamed obects which should be 3506-- materialized for debugging purposes. This means that a memory location 3507-- containing the renamed address should be allocated. This is needed so 3508-- that the debugger can find the entity. 3509 3510-- May_Inherit_Delayed_Rep_Aspects (Flag262) 3511-- Defined in all entities for types and subtypes. Set if the type is 3512-- derived from a type which has delayed rep aspects (marked by the flag 3513-- Has_Delayed_Rep_Aspects being set). In this case, at the freeze point 3514-- for the derived type we know that the parent type is frozen, and if 3515-- a given attribute has not been set for the derived type, we copy the 3516-- value from the parent type. See Freeze.Inherit_Delayed_Rep_Aspects. 3517 3518-- Mechanism (Uint8) (returned as Mechanism_Type) 3519-- Defined in functions and non-generic formal parameters. Indicates 3520-- the mechanism to be used for the function return or for the formal 3521-- parameter. See full description in the spec of Sem_Mech. This field 3522-- is also set (to the default value of zero = Default_Mechanism) in a 3523-- subprogram body entity but not used in this context. 3524 3525-- Modulus (Uint17) [base type only] 3526-- Defined in modular types. Contains the modulus. For the binary case, 3527-- this will be a power of 2, but if Non_Binary_Modulus is set, then it 3528-- will not be a power of 2. 3529 3530-- Must_Be_On_Byte_Boundary (Flag183) 3531-- Defined in entities for types and subtypes. Set if objects of the type 3532-- must always be allocated on a byte boundary (more accurately a storage 3533-- unit boundary). The front end checks that component clauses respect 3534-- this rule, and the backend ensures that record packing does not 3535-- violate this rule. Currently the flag is set only for packed arrays 3536-- longer than 64 bits where the component size is not a power of 2. 3537 3538-- Must_Have_Preelab_Init (Flag208) 3539-- Defined in entities for types and subtypes. Set in the full type of a 3540-- private type or subtype if a pragma Has_Preelaborable_Initialization 3541-- is present for the private type. Used to check that the full type has 3542-- preelaborable initialization at freeze time (this has to be deferred 3543-- to the freeze point because of the rule about overriding Initialize). 3544 3545-- Needs_Activation_Record (Flag306) 3546-- Defined on generated subprogram types. Indicates that a call through 3547-- a named or anonymous access to subprogram requires an activation 3548-- record when compiling with unnesting for C or LLVM. 3549 3550-- Needs_Debug_Info (Flag147) 3551-- Defined in all entities. Set if the entity requires normal debugging 3552-- information to be generated. This is true of all entities that have 3553-- Comes_From_Source set, and also transitively for entities associated 3554-- with such components (e.g. their types). It is true for all entities 3555-- in Debug_Generated_Code mode (-gnatD switch). This is the flag that 3556-- the backend should check to determine whether or not to generate 3557-- debugging information for an entity. Note that callers should always 3558-- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info, 3559-- so that the flag is set properly on subsidiary entities. 3560 3561-- Needs_No_Actuals (Flag22) 3562-- Defined in callable entities (subprograms, entries, access to 3563-- subprograms) which can be called without actuals because all of 3564-- their formals (if any) have default values. This flag simplifies the 3565-- resolution of the syntactic ambiguity involving a call to these 3566-- entities when the return type is an array type, and a call can be 3567-- interpreted as an indexing of the result of the call. It is also 3568-- used to resolve various cases of entry calls. 3569 3570-- Never_Set_In_Source (Flag115) 3571-- Defined in all entities, but can be set only for variables and 3572-- parameters. This flag is set if the object is never assigned a value 3573-- in user source code, either by assignment or by being used as an out 3574-- or in out parameter. Note that this flag is not reset from using an 3575-- initial value, so if you want to test for this case as well, test the 3576-- Has_Initial_Value flag also. 3577-- 3578-- This flag is only for the purposes of issuing warnings, it must not 3579-- be used by the code generator to indicate that the variable is in 3580-- fact a constant, since some assignments in generated code do not 3581-- count (for example, the call to an init proc to assign some but 3582-- not all of the fields in a partially initialized record). The code 3583-- generator should instead use the flag Is_True_Constant. 3584-- 3585-- For the purposes of this warning, the default assignment of access 3586-- variables to null is not considered the assignment of a value (so 3587-- the warning can be given for code that relies on this initial null 3588-- value when no other value is ever set). 3589-- 3590-- In variables and out parameters, if this flag is set after full 3591-- processing of the corresponding declarative unit, it indicates that 3592-- the variable or parameter was never set, and a warning message can 3593-- be issued. 3594-- 3595-- Note: this flag is initially set, and then cleared on encountering 3596-- any construct that might conceivably legitimately set the value. 3597-- Thus during the analysis of a declarative region and its associated 3598-- statement sequence, the meaning of the flag is "not set yet", and 3599-- once this analysis is complete the flag means "never assigned". 3600 3601-- Note: for variables appearing in package declarations, this flag is 3602-- never set. That is because there is no way to tell if some client 3603-- modifies the variable (or, in the case of variables in the private 3604-- part, if some child unit modifies the variables). 3605 3606-- Note: in the case of renamed objects, the flag must be set in the 3607-- ultimate renamed object. Clients noting a possible modification 3608-- should use the Note_Possible_Modification procedure in Sem_Util 3609-- rather than Set_Never_Set_In_Source precisely to deal properly with 3610-- the renaming possibility. 3611 3612-- Next_Component (synthesized) 3613-- Applies to record components. Returns the next component by following 3614-- the chain of declared entities until one is found which corresponds to 3615-- a component (Ekind is E_Component). Any internal types generated from 3616-- the subtype indications of the record components are skipped. Returns 3617-- Empty if no more components. 3618 3619-- Next_Component_Or_Discriminant (synthesized) 3620-- Similar to Next_Component, but includes components and discriminants 3621-- so the input can have either E_Component or E_Discriminant, and the 3622-- same is true for the result. Returns Empty if no more components or 3623-- discriminants in the record. 3624 3625-- Next_Discriminant (synthesized) 3626-- Applies to discriminants returned by First/Next_Discriminant. Returns 3627-- the next language-defined (i.e. perhaps non-girder) discriminant by 3628-- following the chain of declared entities as long as the kind of the 3629-- entity corresponds to a discriminant. Note that the discriminants 3630-- might be the only components of the record. Returns Empty if there 3631-- are no more discriminants. 3632 3633-- Next_Entity (Node2) 3634-- Defined in all entities. The entities of a scope are chained, with 3635-- the head of the list being in the First_Entity field of the scope 3636-- entity. All entities use the Next_Entity field as a forward pointer 3637-- for this list, with Empty indicating the end of the list. Since this 3638-- field is in the base part of the entity, the access routines for this 3639-- field are in Sinfo. 3640 3641-- Next_Formal (synthesized) 3642-- Applies to the entity for a formal parameter. Returns the next formal 3643-- parameter of the subprogram or subprogram type. Returns Empty if there 3644-- are no more formals. 3645 3646-- Next_Formal_With_Extras (synthesized) 3647-- Applies to the entity for a formal parameter. Returns the next 3648-- formal parameter of the subprogram or subprogram type. Returns 3649-- Empty if there are no more formals. The list returned includes 3650-- all the extra formals (see description of Extra_Formal field) 3651 3652-- Next_Index (synthesized) 3653-- Applies to array types and subtypes and to string types and 3654-- subtypes. Yields the next index. The first index is obtained by 3655-- using the First_Index attribute, and then subsequent indexes are 3656-- obtained by applying Next_Index to the previous index. Empty is 3657-- returned to indicate that there are no more indexes. Note that 3658-- unlike most attributes in this package, Next_Index applies to 3659-- nodes for the indexes, not to entities. 3660 3661-- Next_Inlined_Subprogram (Node12) 3662-- Defined in subprograms. Used to chain inlined subprograms used in 3663-- the current compilation, in the order in which they must be compiled 3664-- by the backend to ensure that all inlinings are performed. 3665 3666-- Next_Literal (synthesized) 3667-- Applies to enumeration literals, returns the next literal, or 3668-- Empty if applied to the last literal. This is actually a synonym 3669-- for Next, but its use is preferred in this context. 3670 3671-- No_Dynamic_Predicate_On_Actual (Flag276) 3672-- Defined in discrete types. Set for generic formal types that are used 3673-- in loops and quantified expressions. The corresponing actual cannot 3674-- have dynamic predicates. 3675 3676-- No_Pool_Assigned (Flag131) [root type only] 3677-- Defined in access types. Set if a storage size clause applies to the 3678-- variable with a static expression value of zero. This flag is used to 3679-- generate errors if any attempt is made to allocate or free an instance 3680-- of such an access type. This is set only in the root type, since 3681-- derived types must have the same pool. 3682 3683-- No_Predicate_On_Actual (Flag275) 3684-- Defined in discrete types. Set for generic formal types that are used 3685-- in the spec of a generic package, in constructs that forbid discrete 3686-- types with predicates. 3687 3688-- No_Reordering (Flag239) [implementation base type only] 3689-- Defined in record types. Set only for a base type to which a valid 3690-- pragma No_Component_Reordering applies. 3691 3692-- No_Return (Flag113) 3693-- Defined in all entities. Always false except in the case of procedures 3694-- and generic procedures for which a pragma No_Return is given. 3695 3696-- No_Strict_Aliasing (Flag136) [base type only] 3697-- Defined in access types. Set to direct the backend to avoid any 3698-- optimizations based on an assumption about the aliasing status of 3699-- objects designated by the access type. For the case of the gcc 3700-- backend, the effect is as though all references to objects of 3701-- the type were compiled with -fno-strict-aliasing. This flag is 3702-- set if an unchecked conversion with the access type as a target 3703-- type occurs in the same source unit as the declaration of the 3704-- access type, or if an explicit pragma No_Strict_Aliasing applies. 3705 3706-- No_Tagged_Streams_Pragma (Node32) 3707-- Present in all subtype and type entities. Set for tagged types and 3708-- subtypes (i.e. entities with Is_Tagged_Type set True) if a valid 3709-- pragma/aspect applies to the type. 3710 3711-- Non_Binary_Modulus (Flag58) [base type only] 3712-- Defined in all subtype and type entities. Set for modular integer 3713-- types if the modulus value is other than a power of 2. 3714 3715-- Non_Limited_View (Node19) 3716-- Defined in abstract states and incomplete types that act as shadow 3717-- entities created when analysing a limited with clause (Ada 2005: 3718-- AI-50217). Points to the defining entity of the original declaration. 3719 3720-- Nonzero_Is_True (Flag162) [base type only] 3721-- Defined in enumeration types. Set if any non-zero value is to be 3722-- interpreted as true. Currently this is set for derived Boolean 3723-- types which have a convention of C, C++ or Fortran. 3724 3725-- Normalized_First_Bit (Uint8) 3726-- Defined in components and discriminants. Indicates the normalized 3727-- value of First_Bit for the component, i.e. the offset within the 3728-- lowest addressed storage unit containing part or all of the field. 3729-- Set to No_Uint if no first bit position is assigned yet. 3730 3731-- Normalized_Position (Uint14) 3732-- Defined in components and discriminants. Indicates the normalized 3733-- value of Position for the component, i.e. the offset in storage 3734-- units from the start of the record to the lowest addressed storage 3735-- unit containing part or all of the field. 3736 3737-- Normalized_Position_Max (Uint10) 3738-- Defined in components and discriminants. For almost all cases, this 3739-- is the same as Normalized_Position. The one exception is for the case 3740-- of a discriminated record containing one or more arrays whose length 3741-- depends on discriminants. In this case, the Normalized_Position_Max 3742-- field represents the maximum possible value of Normalized_Position 3743-- assuming min/max values for discriminant subscripts in all fields. 3744-- This is used by Layout in front end layout mode to properly compute 3745-- the maximum size of such records (needed for allocation purposes when 3746-- there are default discriminants, and also for the 'Size value). 3747 3748-- Number_Dimensions (synthesized) 3749-- Applies to array types and subtypes. Returns the number of dimensions 3750-- of the array type or subtype as a value of type Pos. 3751 3752-- Number_Entries (synthesized) 3753-- Applies to concurrent types. Returns the number of entries that are 3754-- declared within the task or protected definition for the type. 3755 3756-- Number_Formals (synthesized) 3757-- Applies to subprograms and subprogram types. Yields the number of 3758-- formals as a value of type Pos. 3759 3760-- Object_Size_Clause (synthesized) 3761-- Applies to entities for types and subtypes. If an object size clause 3762-- is present in the rep item chain for an entity then the attribute 3763-- definition clause node is returned. Otherwise Object_Size_Clause 3764-- returns Empty if no item is present. Usually this is only meaningful 3765-- if the flag Has_Object_Size_Clause is set. This is because when the 3766-- representation item chain is copied for a derived type, it can inherit 3767-- an object size clause that is not applicable to the entity. 3768 3769-- OK_To_Rename (Flag247) 3770-- Defined only in entities for variables. If this flag is set, it 3771-- means that if the entity is used as the initial value of an object 3772-- declaration, the object declaration can be safely converted into a 3773-- renaming to avoid an extra copy. This is set for variables which are 3774-- generated by the expander to hold the result of evaluating some 3775-- expression. Most notably, the local variables used to store the result 3776-- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It 3777-- is only worth setting this flag for composites, since for primitive 3778-- types, it is cheaper to do the copy. 3779 3780-- Optimize_Alignment_Space (Flag241) 3781-- Defined in type, subtype, variable, and constant entities. This 3782-- flag records that the type or object is to be layed out in a manner 3783-- consistent with Optimize_Alignment (Space) mode. The compiler and 3784-- binder ensure a consistent view of any given type or object. If pragma 3785-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3786-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3787 3788-- Optimize_Alignment_Time (Flag242) 3789-- Defined in type, subtype, variable, and constant entities. This 3790-- flag records that the type or object is to be layed out in a manner 3791-- consistent with Optimize_Alignment (Time) mode. The compiler and 3792-- binder ensure a consistent view of any given type or object. If pragma 3793-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3794-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3795 3796-- Original_Access_Type (Node28) 3797-- Defined in E_Access_Subprogram_Type entities. Set only if the access 3798-- type was generated by the expander as part of processing an access- 3799-- to-protected-subprogram type. Points to the access-to-protected- 3800-- subprogram type. 3801 3802-- Original_Array_Type (Node21) 3803-- Defined in modular types and array types and subtypes. Set only if 3804-- the Is_Packed_Array_Impl_Type flag is set, indicating that the type 3805-- is the implementation type for a packed array, and in this case it 3806-- points to the original array type for which this is the packed 3807-- array implementation type. 3808 3809-- Original_Protected_Subprogram (Node41) 3810-- Defined in functions and procedures. Set only on internally built 3811-- dispatching subprograms of protected types to reference their original 3812-- non-dispatching protected subprogram since their names differ. 3813 3814-- Original_Record_Component (Node22) 3815-- Defined in components, including discriminants. The usage depends 3816-- on whether the record is a base type and whether it is tagged. 3817-- 3818-- In base tagged types: 3819-- When the component is inherited in a record extension, it points 3820-- to the original component (the entity of the ancestor component 3821-- which is not itself inherited) otherwise it points to itself. The 3822-- backend uses this attribute to implement the automatic dereference 3823-- in the extension and to apply the transformation: 3824-- 3825-- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp 3826-- 3827-- In base untagged types: 3828-- Always points to itself except for non-girder discriminants, where 3829-- it points to the girder discriminant it renames. 3830-- 3831-- In subtypes (tagged and untagged): 3832-- Points to the component in the base type. 3833 3834-- Overlays_Constant (Flag243) 3835-- Defined in all entities. Set only for E_Constant or E_Variable for 3836-- which there is an address clause that causes the entity to overlay 3837-- a constant object. 3838 3839-- Overridden_Operation (Node26) 3840-- Defined in subprograms. For overriding operations, points to the 3841-- user-defined parent subprogram that is being overridden. Note: this 3842-- attribute uses the same field as Static_Initialization. The latter 3843-- is only defined for internal initialization procedures, for which 3844-- Overridden_Operation is irrelevant. Thus this attribute must not be 3845-- set for init_procs. 3846 3847-- Package_Instantiation (Node26) 3848-- Defined in packages and generic packages. When defined, this field 3849-- references an N_Generic_Instantiation node associated with an 3850-- instantiated package. In the case where the referenced node has 3851-- been rewritten to an N_Package_Specification, the instantiation 3852-- node is available from the Original_Node field of the package spec 3853-- node. This is currently not guaranteed to be set in all cases, but 3854-- when set, the field is used in Get_Unit_Instantiation_Node as 3855-- one of the means of obtaining the instantiation node. Eventually 3856-- it should be set in all cases, including package entities associated 3857-- with formal packages. ??? 3858 3859-- Packed_Array_Impl_Type (Node23) 3860-- Defined in array types and subtypes, except for the string literal 3861-- subtype case, if the corresponding type is packed and implemented 3862-- specially (either bit-packed or packed to eliminate holes in the 3863-- non-contiguous enumeration index types). References the type used to 3864-- represent the packed array, which is either a modular type for short 3865-- static arrays or an array of System.Unsigned in the bit-packed case, 3866-- or a regular array in the non-standard enumeration index case. Note 3867-- that in some situations (internal types and references to fields of 3868-- variant records), it is not always possible to construct this type in 3869-- advance of its use. If this field is empty, then the necessary type 3870-- is declared on the fly for each reference to the array. 3871 3872-- Parameter_Mode (synthesized) 3873-- Applies to formal parameter entities. This is a synonym for Ekind, 3874-- used when obtaining the formal kind of a formal parameter (the result 3875-- is one of E_[In/Out/In_Out]_Parameter). 3876 3877-- Parent_Subtype (Node19) [base type only] 3878-- Defined in E_Record_Type. Set only for derived tagged types, in which 3879-- case it points to the subtype of the parent type. This is the type 3880-- that is used as the Etype of the _parent field. 3881 3882-- Part_Of_Constituents (Elist10) 3883-- Present in abstract state and variable entities. Contains all 3884-- constituents that are subject to indicator Part_Of (both aspect and 3885-- option variants). 3886 3887-- Part_Of_References (Elist11) 3888-- Present in variable entities. Contains all references to the variable 3889-- when it is subject to pragma Part_Of. If the variable is a constituent 3890-- of a single protected/task type, the references are examined as they 3891-- must appear only within the type defintion and the corresponding body. 3892 3893-- Partial_Invariant_Procedure (synthesized) 3894-- Defined in types and subtypes. Set for private types when one or more 3895-- [class-wide] type invariants apply to them. Points to the entity for a 3896-- procedure which checks the invariant. This invariant procedure takes a 3897-- single argument of the given type, and returns if the invariant holds, 3898-- or raises exception Assertion_Error with an appropriate message if it 3899-- does not hold. This attribute is defined but always Empty for private 3900-- subtypes. This attribute is also set for the corresponding full type. 3901-- 3902-- Note: the reason this is marked as a synthesized attribute is that the 3903-- way this is stored is as an element of the Subprograms_For_Type field. 3904 3905-- Partial_Refinement_Constituents (synthesized) 3906-- Defined in abstract state entities. Returns the constituents that 3907-- refine the state in the current scope, which are allowed in a global 3908-- refinement in this scope. These consist of those constituents that are 3909-- abstract states with no or only partial refinement visible, and those 3910-- that are not themselves abstract states. 3911 3912-- Partial_View_Has_Unknown_Discr (Flag280) 3913-- Present in all types. Set to Indicate that the partial view of a type 3914-- has unknown discriminants. A default initialization of an object of 3915-- the type does not require an invariant check (AI12-0133). 3916 3917-- Pending_Access_Types (Elist15) 3918-- Defined in all types. Set for incomplete, private, Taft-amendment 3919-- types, and their corresponding full views. This list contains all 3920-- access types, both named and anonymous, declared between the partial 3921-- and the full view. The list is used by the finalization machinery to 3922-- ensure that the finalization masters of all pending access types are 3923-- fully initialized when the full view is frozen. 3924 3925-- Postconditions_Proc (Node14) 3926-- Defined in functions, procedures, entries, and entry families. Refers 3927-- to the entity of the _Postconditions procedure used to check contract 3928-- assertions on exit from a subprogram. 3929 3930-- Predicate_Function (synthesized) 3931-- Defined in all types. Set for types for which (Has_Predicates is True) 3932-- and for which a predicate procedure has been built that tests that the 3933-- specified predicates are True. Contains the entity for the function 3934-- which takes a single argument of the given type, and returns True if 3935-- the predicate holds and False if it does not. 3936-- 3937-- Note: flag Has_Predicate does not imply that Predicate_Function is set 3938-- to a non-empty entity; this happens, for example, for itypes created 3939-- when instantiating generic units with private types with predicates. 3940-- However, if an explicit pragma Predicate or Predicate aspect is given 3941-- either for private or full type declaration then both Has_Predicates 3942-- and a non-empty Predicate_Function will be set on both the partial and 3943-- full views of the type. 3944-- 3945-- Note: the reason this is marked as a synthesized attribute is that the 3946-- way this is stored is as an element of the Subprograms_For_Type field. 3947 3948-- Predicate_Function_M (synthesized) 3949-- Defined in all types. Present only if Predicate_Function is present, 3950-- and only if the predicate function has Raise_Expression nodes. It 3951-- is the special version created for membership tests, where if one of 3952-- these raise expressions is executed, the result is to return False. 3953 3954-- Predicated_Parent (Node38) 3955-- Defined on itypes created by subtype indications, when the parent 3956-- subtype has predicates. The itype shares the Predicate_Function 3957-- of the predicated parent, but this function may not have been built 3958-- at the point the Itype is constructed, so this attribute allows its 3959-- retrieval at the point a predicate check needs to be generated. 3960-- The utility Predicate_Function takes this link into account. 3961 3962-- Predicates_Ignored (Flag288) 3963-- Defined on all types. Indicates whether the subtype declaration is in 3964-- a context where Assertion_Policy is Ignore, in which case no checks 3965-- (static or dynamic) must be generated for objects of the type. 3966 3967-- Prev_Entity (Node36) 3968-- Defined in all entities. The entities of a scope are chained, and this 3969-- field is used as a backward pointer for this entity list - effectivly 3970-- making the entity chain doubly-linked. 3971 3972-- Primitive_Operations (synthesized) 3973-- Defined in concurrent types, tagged record types and subtypes, tagged 3974-- private types and tagged incomplete types. For concurrent types whose 3975-- Corresponding_Record_Type (CRT) is available, returns the list of 3976-- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist. 3977-- For all the other types returns the Direct_Primitive_Operations. 3978 3979-- Prival (Node17) 3980-- Defined in private components of protected types. Refers to the entity 3981-- of the component renaming declaration generated inside protected 3982-- subprograms, entries or barrier functions. 3983 3984-- Prival_Link (Node20) 3985-- Defined in constants and variables which rename private components of 3986-- protected types. Set to the original private component. 3987 3988-- Private_Dependents (Elist18) 3989-- Defined in private (sub)types. Records the subtypes of the private 3990-- type, derivations from it, and records and arrays with components 3991-- dependent on the type. 3992-- 3993-- The subtypes are traversed when installing and deinstalling (the full 3994-- view of) a private type in order to ensure correct view of the 3995-- subtypes. 3996-- 3997-- Used in similar fashion for incomplete types: holds list of subtypes 3998-- of these incomplete types that have discriminant constraints. The 3999-- full views of these subtypes are constructed when the full view of 4000-- the incomplete type is processed. 4001 4002-- In addition, if the incomplete type is the designated type in an 4003-- access definition for an access parameter, the operation may be 4004-- a dispatching primitive operation, which is only known when the full 4005-- declaration of the type is seen. Subprograms that have such an 4006-- access parameter are also placed in the list of private_dependents. 4007 4008-- Protected_Body_Subprogram (Node11) 4009-- Defined in protected operations. References the entity for the 4010-- subprogram which implements the body of the operation. 4011 4012-- Protected_Formal (Node22) 4013-- Defined in formal parameters (in, in out and out parameters). Used 4014-- only for formals of protected operations. References corresponding 4015-- formal parameter in the unprotected version of the operation that 4016-- is created during expansion. 4017 4018-- Protected_Subprogram (Node39) 4019-- Defined in functions and procedures. Set for the pair of subprograms 4020-- which emulate the runtime semantics of a protected subprogram. Denotes 4021-- the entity of the origial protected subprogram. 4022 4023-- Protection_Object (Node23) 4024-- Applies to protected entries, entry families and subprograms. Denotes 4025-- the entity which is used to rename the _object component of protected 4026-- types. 4027 4028-- Reachable (Flag49) 4029-- Defined in labels. The flag is set over the range of statements in 4030-- which a goto to that label is legal. 4031 4032-- Receiving_Entry (Node19) 4033-- Defined in procedures. Set for an internally generated procedure which 4034-- wraps the original statements of an accept alternative. Designates the 4035-- entity of the task entry being accepted. 4036 4037-- Referenced (Flag156) 4038-- Defined in all entities. Set if the entity is referenced, except for 4039-- the case of an appearance of a simple variable that is not a renaming 4040-- as the left side of an assignment in which case Referenced_As_LHS is 4041-- set instead, or a similar appearance as an out parameter actual, in 4042-- which case Referenced_As_Out_Parameter is set. 4043 4044-- Referenced_As_LHS (Flag36): 4045-- Defined in all entities. This flag is set instead of Referenced if a 4046-- simple variable that is not a renaming appears as the left side of an 4047-- assignment. The reason we distinguish this kind of reference is that 4048-- we have a separate warning for variables that are only assigned and 4049-- never read. 4050 4051-- Referenced_As_Out_Parameter (Flag227): 4052-- Defined in all entities. This flag is set instead of Referenced if a 4053-- simple variable that is not a renaming appears as an actual for an out 4054-- formal. The reason we distinguish this kind of reference is that 4055-- we have a separate warning for variables that are only assigned and 4056-- never read, and out parameters are a special case. 4057 4058-- Refinement_Constituents (Elist8) 4059-- Present in abstract state entities. Contains all the constituents that 4060-- refine the state, in other words, all the hidden states that appear in 4061-- the constituent_list of aspect/pragma Refined_State. 4062 4063-- Register_Exception_Call (Node20) 4064-- Defined in exception entities. When an exception is declared, 4065-- a call is expanded to Register_Exception. This field points to 4066-- the expanded N_Procedure_Call_Statement node for this call. It 4067-- is used for Import/Export_Exception processing to modify the 4068-- register call to make appropriate entries in the special tables 4069-- used for handling these pragmas at run time. 4070 4071-- Related_Array_Object (Node25) 4072-- Defined in array types and subtypes. Used only for the base type 4073-- and subtype created for an anonymous array object. Set to point 4074-- to the entity of the corresponding array object. Currently used 4075-- only for type-related error messages. 4076 4077-- Related_Expression (Node24) 4078-- Defined in variables and types. When Set for internally generated 4079-- entities, it may be used to denote the source expression whose 4080-- elaboration created the variable declaration. If set, it is used 4081-- for generating clearer messages from CodePeer. It is used on source 4082-- entities that are variables in iterator specifications, to provide 4083-- a link to the container that is the domain of iteration. This allows 4084-- for better cross-reference information when the loop modifies elements 4085-- of the container, and suppresses spurious warnings. 4086-- 4087-- Shouldn't it also be used for the same purpose in errout? It seems 4088-- odd to have two mechanisms here??? 4089 4090-- Related_Instance (Node15) 4091-- Defined in the wrapper packages created for subprogram instances. 4092-- The internal subprogram that implements the instance is inside the 4093-- wrapper package, but for debugging purposes its external symbol 4094-- must correspond to the name and scope of the related instance. 4095 4096-- Related_Type (Node27) 4097-- Defined in components, constants and variables. Set when there is an 4098-- associated dispatch table to point to entities containing primary or 4099-- secondary tags. Not set in the _tag component of record types. 4100 4101-- Relative_Deadline_Variable (Node28) [implementation base type only] 4102-- Defined in task type entities. This flag is set if a valid and 4103-- effective pragma Relative_Deadline applies to the base type. Points 4104-- to the entity for a variable that is created to hold the value given 4105-- in a Relative_Deadline pragma for a task type. 4106 4107-- Renamed_Entity (Node18) 4108-- Defined in exception, generic unit, package, and subprogram entities. 4109-- Set when the entity is defined by a renaming declaration. Denotes the 4110-- renamed entity, or transitively the ultimate renamed entity if there 4111-- is a chain of renaming declarations. Empty if no renaming. 4112 4113-- Renamed_In_Spec (Flag231) 4114-- Defined in package entities. If a package renaming occurs within 4115-- a package spec, then this flag is set on the renamed package. The 4116-- purpose is to prevent a warning about unused entities in the renamed 4117-- package. Such a warning would be inappropriate since clients of the 4118-- package can see the entities in the package via the renaming. 4119 4120-- Renamed_Object (Node18) 4121-- Defined in components, constants, discriminants, formal parameters, 4122-- generic formals, loop parameters, and variables. Set to non-Empty if 4123-- the object was declared by a renaming declaration. For constants and 4124-- variables, the attribute references the tree node for the name of the 4125-- renamed object. For formal parameters, the field is used in inlining 4126-- and maps the entities of all formal parameters of a subprogram to the 4127-- entities of the corresponding actuals. For formals of a task entry, 4128-- the attribute denotes the local renaming that replaces the actual 4129-- within an accept statement. For all remaining cases (discriminants, 4130-- loop parameters) the field is Empty. 4131 4132-- Renaming_Map (Uint9) 4133-- Defined in generic subprograms, generic packages, and their 4134-- instances. Also defined in the instances of the corresponding 4135-- bodies. Denotes the renaming map (generic entities => instance 4136-- entities) used to construct the instance by givin an index into 4137-- the tables used to represent these maps. See Sem_Ch12 for further 4138-- details. The maps for package instances are also used when the 4139-- instance is the actual corresponding to a formal package. 4140 4141-- Requires_Overriding (Flag213) 4142-- Defined in all subprograms and entries. Set for subprograms that 4143-- require overriding as defined by RM-2005-3.9.3(6/2). Note that this 4144-- is True only for implicitly declared subprograms; it is not set on the 4145-- parent type's subprogram. See also Is_Abstract_Subprogram. 4146 4147-- Return_Applies_To (Node8) 4148-- Defined in E_Return_Statement. Points to the entity representing 4149-- the construct to which the return statement applies, as defined in 4150-- RM-6.5(4/2). Note that a (simple) return statement within an 4151-- extended_return_statement applies to the extended_return_statement, 4152-- even though it causes the whole function to return. 4153 4154-- Return_Present (Flag54) 4155-- Defined in function and generic function entities. Set if the 4156-- function contains a return statement (used for error checking). 4157-- This flag can also be set in procedure and generic procedure 4158-- entities (for convenience in setting it), but is only tested 4159-- for the function case. 4160 4161-- Returns_By_Ref (Flag90) 4162-- Defined in function entities. Set if the function returns the result 4163-- by reference, either because its return type is a by-reference-type 4164-- or because the function explicitly uses the secondary stack. 4165 4166-- Reverse_Bit_Order (Flag164) [base type only] 4167-- Defined in all record type entities. Set if entity has a Bit_Order 4168-- aspect (set by an aspect clause or attribute definition clause) that 4169-- has reversed the order of bits from the default value. When this flag 4170-- is set, a component clause must specify a set of bits entirely within 4171-- a single storage unit (Ada 95) or within a single machine scalar (see 4172-- Ada 2005 AI-133), or must occupy an integral number of storage units. 4173 4174-- Reverse_Storage_Order (Flag93) [base type only] 4175-- Defined in all record and array type entities. Set if entity has a 4176-- Scalar_Storage_Order aspect (set by an aspect clause or attribute 4177-- definition clause) that has reversed the order of storage elements 4178-- from the default value. When this flag is set for a record type, 4179-- the Bit_Order aspect must be set to the same value (either explicitly 4180-- or as the target default value). 4181 4182-- Rewritten_For_C (Flag287) 4183-- Defined on functions that return a constrained array type, when 4184-- Modify_Tree_For_C is set. Indicates that a procedure with an extra 4185-- out parameter has been created for it, and calls must be rewritten as 4186-- calls to the new procedure. 4187 4188-- RM_Size (Uint13) 4189-- Defined in all type and subtype entities. Contains the value of 4190-- type'Size as defined in the RM. See also the Esize field and 4191-- and the description on "Handling of Type'Size Values". A value 4192-- of zero in this field for a non-discrete type means that 4193-- the front end has not yet determined the size value. For the 4194-- case of a discrete type, this field is always set by the front 4195-- end and zero is a legitimate value for a type with one value. 4196 4197-- Root_Type (synthesized) 4198-- Applies to all type entities. For class-wide types, returns the root 4199-- type of the class covered by the CW type, otherwise returns the 4200-- ultimate derivation ancestor of the given type. This function 4201-- preserves the view, i.e. the Root_Type of a partial view is the 4202-- partial view of the ultimate ancestor, the Root_Type of a full view 4203-- is the full view of the ultimate ancestor. Note that this function 4204-- does not correspond exactly to the use of root type in the RM, since 4205-- in the RM root type applies to a class of types, not to a type. 4206 4207-- Scalar_Range (Node20) 4208-- Defined in all scalar types (including modular types, where the 4209-- bounds are 0 .. modulus - 1). References a node in the tree that 4210-- contains the bounds for the range. Note that this information 4211-- could be obtained by rummaging around the tree, but it is more 4212-- convenient to have it immediately at hand in the entity. The 4213-- contents of Scalar_Range can either be an N_Subtype_Indication 4214-- node (with a constraint), a Range node, or an Integer_Type_Definition, 4215-- but not a simple subtype reference (a subtype is converted into a 4216-- explicit range). 4217 4218-- Scale_Value (Uint16) 4219-- Defined in decimal fixed-point types and subtypes. Contains the scale 4220-- for the type (i.e. the value of type'Scale = the number of decimal 4221-- digits after the decimal point). 4222 4223-- Scope (Node3) 4224-- Defined in all entities. Points to the entity for the scope (block, 4225-- loop, subprogram, package etc.) in which the entity is declared. 4226-- Since this field is in the base part of the entity node, the access 4227-- routines for this field are in Sinfo. Note that for a child unit, 4228-- the Scope will be the parent package, and for a root library unit, 4229-- the Scope will be Standard. 4230 4231-- Scope_Depth (synthesized) 4232-- Applies to program units, blocks, concurrent types and entries, and 4233-- also to record types, i.e. to any entity that can appear on the scope 4234-- stack. Yields the scope depth value, which for those entities other 4235-- than records is simply the scope depth value, for record entities, it 4236-- is the Scope_Depth of the record scope. 4237 4238-- Scope_Depth_Value (Uint22) 4239-- Defined in program units, blocks, concurrent types, and entries. 4240-- Indicates the number of scopes that statically enclose the declaration 4241-- of the unit or type. Library units have a depth of zero. Note that 4242-- record types can act as scopes but do NOT have this field set (see 4243-- Scope_Depth above). 4244 4245-- Scope_Depth_Set (synthesized) 4246-- Applies to a special predicate function that returns a Boolean value 4247-- indicating whether or not the Scope_Depth field has been set. It is 4248-- needed, since returns an invalid value in this case. 4249 4250-- Sec_Stack_Needed_For_Return (Flag167) 4251-- Defined in scope entities (blocks, entries, entry families, functions, 4252-- and procedures). Set to True when secondary stack is used to hold the 4253-- returned value of a function and thus should not be released on scope 4254-- exit. 4255 4256-- Shared_Var_Procs_Instance (Node22) 4257-- Defined in variables. Set non-Empty only if Is_Shared_Passive is 4258-- set, in which case this is the entity for the associated instance of 4259-- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details. 4260 4261-- Size_Check_Code (Node19) 4262-- Defined in constants and variables. Normally Empty. Set if code is 4263-- generated to check the size of the object. This field is used to 4264-- suppress this code if a subsequent address clause is encountered. 4265 4266-- Size_Clause (synthesized) 4267-- Applies to all entities. If a size clause is present in the rep 4268-- item chain for an entity then the attribute definition clause node 4269-- for the size clause is returned. Otherwise Size_Clause returns Empty 4270-- if no item is present. Usually this is only meaningful if the flag 4271-- Has_Size_Clause is set. This is because when the representation item 4272-- chain is copied for a derived type, it can inherit a size clause that 4273-- is not applicable to the entity. 4274 4275-- Size_Depends_On_Discriminant (Flag177) 4276-- Defined in all entities for types and subtypes. Indicates that the 4277-- size of the type depends on the value of one or more discriminants. 4278-- Currently, this flag is only set for arrays which have one or more 4279-- bounds depending on a discriminant value. 4280 4281-- Size_Known_At_Compile_Time (Flag92) 4282-- Defined in all entities for types and subtypes. Indicates that the 4283-- size of objects of the type is known at compile time. This flag is 4284-- used to optimize some generated code sequences, and also to enable 4285-- some error checks (e.g. disallowing component clauses on variable 4286-- length objects). It is set conservatively (i.e. if it is True, the 4287-- size is certainly known at compile time, if it is False, then the 4288-- size may or may not be known at compile time, but the code will 4289-- assume that it is not known). Note that the value may be known only 4290-- to the back end, so the fact that this flag is set does not mean that 4291-- the front end can access the value. 4292 4293-- Small_Value (Ureal21) 4294-- Defined in fixed point types. Points to the universal real for the 4295-- Small of the type, either as given in a representation clause, or 4296-- as computed (as a power of two) by the compiler. 4297 4298-- SPARK_Aux_Pragma (Node41) 4299-- Present in concurrent type, [generic] package spec and package body 4300-- entities. For concurrent types and package specs it refers to the 4301-- SPARK mode setting for the private part. This field points to the 4302-- N_Pragma node that either appears in the private part or is inherited 4303-- from the enclosing context. For package bodies, it refers to the SPARK 4304-- mode of the elaboration sequence after the BEGIN. The fields points to 4305-- the N_Pragma node that either appears in the statement sequence or is 4306-- inherited from the enclosing context. In all cases, if the pragma is 4307-- inherited, then the SPARK_Aux_Pragma_Inherited flag is set. 4308 4309-- SPARK_Aux_Pragma_Inherited (Flag266) 4310-- Present in concurrent type, [generic] package spec and package body 4311-- entities. Set if the SPARK_Aux_Pragma field points to a pragma that is 4312-- inherited, rather than a local one. 4313 4314-- SPARK_Pragma (Node40) 4315-- Present in the following entities: 4316-- 4317-- abstract states 4318-- constants 4319-- entries 4320-- operators 4321-- [generic] packages 4322-- package bodies 4323-- [generic] subprograms 4324-- subprogram bodies 4325-- variables 4326-- types 4327-- 4328-- Points to the N_Pragma node that applies to the initial declaration or 4329-- body. This is either set by a local SPARK_Mode pragma or is inherited 4330-- from the context (from an outer scope for the spec case or from the 4331-- spec for the body case). In the case where the attribute is inherited, 4332-- flag SPARK_Pragma_Inherited is set. Empty if no SPARK_Mode pragma is 4333-- applicable. 4334 4335-- SPARK_Pragma_Inherited (Flag265) 4336-- Present in the following entities: 4337-- 4338-- abstract states 4339-- constants 4340-- entries 4341-- operators 4342-- [generic] packages 4343-- package bodies 4344-- [generic] subprograms 4345-- subprogram bodies 4346-- variables 4347-- types 4348-- 4349-- Set if the SPARK_Pragma attribute points to an inherited pragma rather 4350-- than a local one. 4351 4352-- Spec_Entity (Node19) 4353-- Defined in package body entities. Points to corresponding package 4354-- spec entity. Also defined in subprogram body parameters in the 4355-- case where there is a separate spec, where this field references 4356-- the corresponding parameter entities in the spec. 4357 4358-- SSO_Set_High_By_Default (Flag273) [base type only] 4359-- Defined for record and array types. Set in the base type if a pragma 4360-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4361-- the record or array was declared and therefore applies to it. 4362 4363-- SSO_Set_Low_By_Default (Flag272) [base type only] 4364-- Defined for record and array types. Set in the base type if a pragma 4365-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4366-- the record or array was declared and therefore applies to it. 4367 4368-- Static_Discrete_Predicate (List25) 4369-- Defined in discrete types/subtypes with static predicates (with the 4370-- two flags Has_Predicates and Has_Static_Predicate set). Set if the 4371-- type/subtype has a static predicate. Points to a list of expression 4372-- and N_Range nodes that represent the predicate in canonical form. The 4373-- canonical form has entries sorted in ascending order, with duplicates 4374-- eliminated, and adjacent ranges coalesced, so that there is always a 4375-- gap in the values between successive entries. The entries in this list 4376-- are fully analyzed and typed with the base type of the subtype. Note 4377-- that all entries are static and have values within the subtype range. 4378 4379-- Static_Elaboration_Desired (Flag77) 4380-- Defined in library-level packages. Set by the pragma of the same 4381-- name, to indicate that static initialization must be attempted for 4382-- all types declared in the package, and that a warning must be emitted 4383-- for those types to which static initialization is not available. 4384 4385-- Static_Initialization (Node30) 4386-- Defined in initialization procedures for types whose objects can be 4387-- initialized statically. The value of this attribute is a positional 4388-- aggregate whose components are compile-time static values. Used 4389-- when available in object declarations to eliminate the call to the 4390-- initialization procedure, and to minimize elaboration code. Note: 4391-- This attribute uses the same field as Overridden_Operation, which is 4392-- irrelevant in init_procs. 4393 4394-- Static_Real_Or_String_Predicate (Node25) 4395-- Defined in real types/subtypes with static predicates (with the two 4396-- flags Has_Predicates and Has_Static_Predicate set). Set if the type 4397-- or subtype has a static predicate. Points to the return expression 4398-- of the predicate function. This is the original expression given as 4399-- the predicate except that occurrences of the type are replaced by 4400-- occurrences of the formal parameter of the predicate function (note 4401-- that the spec of this function including this formal parameter name 4402-- is available from the Subprograms_For_Type field; it can be accessed 4403-- as Predicate_Function (typ)). Also, in the case where a predicate is 4404-- inherited, the expression is of the form: 4405-- 4406-- xxxPredicate (typ2 (ent)) AND THEN expression 4407-- 4408-- where typ2 is the type from which the predicate is inherited, ent is 4409-- the entity for the current predicate function, and xxxPredicate is the 4410-- inherited predicate (from typ2). Finally for a predicate that inherits 4411-- from another predicate but does not add a predicate of its own, the 4412-- expression may consist of the above xxxPredicate call on its own. 4413 4414-- Status_Flag_Or_Transient_Decl (Node15) 4415-- Defined in constant, loop, and variable entities. Applies to objects 4416-- that require special treatment by the finalization machinery, such as 4417-- extended return results, IF and CASE expression results, and objects 4418-- inside N_Expression_With_Actions nodes. The attribute contains the 4419-- entity of a flag which specifies particular behavior over a region of 4420-- code or the declaration of a "hook" object. 4421-- In which case is it a flag, or a hook object??? 4422 4423-- Storage_Size_Variable (Node26) [implementation base type only] 4424-- Defined in access types and task type entities. This flag is set 4425-- if a valid and effective pragma Storage_Size applies to the base 4426-- type. Points to the entity for a variable that is created to 4427-- hold the value given in a Storage_Size pragma for an access 4428-- collection or a task type. Note that in the access type case, 4429-- this field is defined only in the root type (since derived types 4430-- share the same storage pool). 4431 4432-- Stored_Constraint (Elist23) 4433-- Defined in entities that can have discriminants (concurrent types 4434-- subtypes, record types and subtypes, private types and subtypes, 4435-- limited private types and subtypes and incomplete types). Points 4436-- to an element list containing the expressions for each of the 4437-- stored discriminants for the record (sub)type. 4438 4439-- Stores_Attribute_Old_Prefix (Flag270) 4440-- Defined in constants. Set when the constant has been generated to save 4441-- the value of attribute 'Old's prefix. 4442 4443-- Strict_Alignment (Flag145) [implementation base type only] 4444-- Defined in all type entities. Indicates that some containing part 4445-- is either aliased or tagged. This prohibits packing the object 4446-- tighter than its natural size and alignment. 4447 4448-- String_Literal_Length (Uint16) 4449-- Defined in string literal subtypes (which are created to correspond 4450-- to string literals in the program). Contains the length of the string 4451-- literal. 4452 4453-- String_Literal_Low_Bound (Node18) 4454-- Defined in string literal subtypes (which are created to correspond 4455-- to string literals in the program). Contains an expression whose 4456-- value represents the low bound of the literal. This is a copy of 4457-- the low bound of the applicable index constraint if there is one, 4458-- or a copy of the low bound of the index base type if not. 4459 4460-- Subprograms_For_Type (Elist29) 4461-- Defined in all types. The list may contain the entities of the default 4462-- initial condition procedure, invariant procedure, and the two versions 4463-- of the predicate function. 4464-- 4465-- Historical note: This attribute used to be a direct linked list of 4466-- entities rather than an Elist. The Elist allows greater flexibility 4467-- in inheritance of subprograms between views of the same type. 4468 4469-- Subps_Index (Uint24) 4470-- Present in subprogram entries. Set if the subprogram contains nested 4471-- subprograms, or is a subprogram nested within such a subprogram. Holds 4472-- the index in the Exp_Unst.Subps table for the subprogram. Note that 4473-- for the outer level subprogram, this is the starting index in the Subp 4474-- table for the entries for this subprogram. 4475 4476-- Suppress_Elaboration_Warnings (Flag303) 4477-- NOTE: this flag is relevant only for the legacy ABE mechanism and 4478-- should not be used outside of that context. 4479-- 4480-- Defined in all entities, can be set only for subprogram entities and 4481-- for variables. If this flag is set then Sem_Elab will not generate 4482-- elaboration warnings for the subprogram or variable. Suppression of 4483-- such warnings is automatic for subprograms for which elaboration 4484-- checks are suppressed (without the need to set this flag), but the 4485-- flag is also set for various internal entities (such as init procs) 4486-- which are known not to generate any possible access before elaboration 4487-- and it is set on variables when a warning is given to avoid multiple 4488-- elaboration warnings for the same variable. 4489 4490-- Suppress_Initialization (Flag105) 4491-- Defined in all variable, type and subtype entities. If set for a base 4492-- type, then the generation of initialization procedures is suppressed 4493-- for the type. Any other implicit initialiation (e.g. from the use of 4494-- pragma Initialize_Scalars) is also suppressed if this flag is set for 4495-- either the subtype in question, or for the base type. For variables, 4496-- this flag suppresses all implicit initialization for the object, even 4497-- if the type would normally require initialization. Set by use of 4498-- pragma Suppress_Initialization and also for internal entities where 4499-- we know that no initialization is required. For example, enumeration 4500-- image table entities set it. 4501 4502-- Suppress_Style_Checks (Flag165) 4503-- Defined in all entities. Suppresses any style checks specifically 4504-- associated with the given entity if set. 4505 4506-- Suppress_Value_Tracking_On_Call (Flag217) 4507-- Defined in all entities. Set in a scope entity if value tracking is to 4508-- be suppressed on any call within the scope. Used when an access to a 4509-- local subprogram is computed, to deal with the possibility that this 4510-- value may be passed around, and if used, may clobber a local variable. 4511 4512-- Task_Body_Procedure (Node25) 4513-- Defined in task types and subtypes. Points to the entity for the task 4514-- task body procedure (as further described in Exp_Ch9, task bodies are 4515-- expanded into procedures). A convenient function to retrieve this 4516-- field is Sem_Util.Get_Task_Body_Procedure. 4517-- 4518-- The last sentence is odd??? Why not have Task_Body_Procedure go to the 4519-- Underlying_Type of the Root_Type??? 4520 4521-- Thunk_Entity (Node31) 4522-- Defined in functions and procedures which have been classified as 4523-- Is_Thunk. Set to the target entity called by the thunk. 4524 4525-- Treat_As_Volatile (Flag41) 4526-- Defined in all type entities, and also in constants, components and 4527-- variables. Set if this entity is to be treated as volatile for code 4528-- generation purposes. Always set if Is_Volatile is set, but can also 4529-- be set as a result of situations (such as address overlays) where 4530-- the front end wishes to force volatile handling to inhibit aliasing 4531-- optimization which might be legally ok, but is undesirable. Note 4532-- that the backend always tests this flag rather than Is_Volatile. 4533-- The front end tests Is_Volatile if it is concerned with legality 4534-- checks associated with declared volatile variables, but if the test 4535-- is for the purposes of suppressing optimizations, then the front 4536-- end should test Treat_As_Volatile rather than Is_Volatile. 4537-- 4538-- Note: before testing Treat_As_Volatile, consider whether it would 4539-- be more appropriate to use Exp_Util.Is_Volatile_Reference instead, 4540-- which catches more cases of volatile references. 4541 4542-- Type_High_Bound (synthesized) 4543-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4544-- the high bound of a scalar type. The returned value is literal for a 4545-- base type, but may be an expression in the case of scalar type with 4546-- dynamic bounds. Note that in the case of a fixed point type, the high 4547-- bound is in units of small, and is an integer. 4548 4549-- Type_Low_Bound (synthesized) 4550-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4551-- the low bound of a scalar type. The returned value is literal for a 4552-- base type, but may be an expression in the case of scalar type with 4553-- dynamic bounds. Note that in the case of a fixed point type, the low 4554-- bound is in units of small, and is an integer. 4555 4556-- Underlying_Full_View (Node19) 4557-- Defined in private subtypes that are the completion of other private 4558-- types, or in private types that are derived from private subtypes. If 4559-- the full view of a private type T is derived from another private type 4560-- with discriminants Td, the full view of T is also private, and there 4561-- is no way to attach to it a further full view that would convey the 4562-- structure of T to the backend. The Underlying_Full_View is an 4563-- attribute of the full view that is a subtype of Td with the same 4564-- constraint as the declaration for T. The declaration for this subtype 4565-- is built at the point of the declaration of T, either as completion, 4566-- or as a subtype declaration where the base type is private and has a 4567-- private completion. If Td is already constrained, then its full view 4568-- can serve directly as the full view of T. 4569 4570-- Underlying_Record_View (Node28) 4571-- Defined in record types. Set for record types that are extensions of 4572-- types with unknown discriminants, and also set for internally built 4573-- underlying record views to reference its original record type. Record 4574-- types that are extensions of types with unknown discriminants do not 4575-- have a completion, but they cannot be used without having some 4576-- discriminated view at hand. This view is a record type with the same 4577-- structure, whose parent type is the full view of the parent in the 4578-- original type extension. 4579 4580-- Underlying_Type (synthesized) 4581-- Applies to all entities. This is the identity function except in the 4582-- case where it is applied to an incomplete or private type, in which 4583-- case it is the underlying type of the type declared by the completion, 4584-- or Empty if the completion has not yet been encountered and analyzed. 4585-- 4586-- Note: the reason this attribute applies to all entities, and not just 4587-- types, is to legitimize code where Underlying_Type is applied to an 4588-- entity which may or may not be a type, with the intent that if it is a 4589-- type, its underlying type is taken. 4590-- 4591-- Note also that the value of this attribute is interesting only after 4592-- the full view of the parent type has been processed. If the parent 4593-- type is declared in an enclosing package, the attribute will be non- 4594-- trivial only after the full view of the type has been analyzed. 4595 4596-- Universal_Aliasing (Flag216) [implementation base type only] 4597-- Defined in all type entities. Set to direct the back-end to avoid 4598-- any optimizations based on type-based alias analysis for this type. 4599-- Indicates that objects of this type can alias objects of any other 4600-- types, which guarantees that any objects can be referenced through 4601-- access types designating this type safely, whatever the actual type 4602-- of these objects. In other words, the effect is as though access 4603-- types designating this type were subject to No_Strict_Aliasing. 4604 4605-- Unset_Reference (Node16) 4606-- Defined in variables and out parameters. This is normally Empty. It 4607-- is set to point to an identifier that represents a reference to the 4608-- entity before any value has been set. Only the first such reference 4609-- is identified. This field is used to generate a warning message if 4610-- necessary (see Sem_Warn.Check_Unset_Reference). 4611 4612-- Used_As_Generic_Actual (Flag222) 4613-- Defined in all entities, set if the entity is used as an argument to 4614-- a generic instantiation. Used to tune certain warning messages, and 4615-- in checking type conformance within an instantiation that involves 4616-- incomplete formal and actual types. 4617 4618-- Uses_Lock_Free (Flag188) 4619-- Defined in protected type entities. Set to True when the Lock Free 4620-- implementation is used for the protected type. This implementation is 4621-- based on atomic transactions and doesn't require anymore the use of 4622-- Protection object (see System.Tasking.Protected_Objects). 4623 4624-- Uses_Sec_Stack (Flag95) 4625-- Defined in scope entities (blocks, entries, entry families, functions, 4626-- loops, and procedures). Set to True when the secondary stack is used 4627-- in this scope and must be released on exit unless flag 4628-- Sec_Stack_Needed_For_Return is set. 4629 4630-- Validated_Object (Node38) 4631-- Defined in variables. Contains the object whose value is captured by 4632-- the variable for validity check purposes. 4633 4634-- Warnings_Off (Flag96) 4635-- Defined in all entities. Set if a pragma Warnings (Off, entity-name) 4636-- is used to suppress warnings for a given entity. It is also used by 4637-- the compiler in some situations to kill spurious warnings. Note that 4638-- clients should generally not test this flag directly, but instead 4639-- use function Has_Warnings_Off. 4640 4641-- Warnings_Off_Used (Flag236) 4642-- Defined in all entities. Can only be set if Warnings_Off is set. If 4643-- set indicates that a warning was suppressed by the Warnings_Off flag, 4644-- and Unmodified/Unreferenced would not have suppressed the warning. 4645 4646-- Warnings_Off_Used_Unmodified (Flag237) 4647-- Defined in all entities. Can only be set if Warnings_Off is set and 4648-- Has_Pragma_Unmodified is not set. If set indicates that a warning was 4649-- suppressed by the Warnings_Off status but that pragma Unmodified 4650-- would also have suppressed the warning. 4651 4652-- Warnings_Off_Used_Unreferenced (Flag238) 4653-- Defined in all entities. Can only be set if Warnings_Off is set and 4654-- Has_Pragma_Unreferenced is not set. If set indicates that a warning 4655-- was suppressed by the Warnings_Off status but that pragma Unreferenced 4656-- would also have suppressed the warning. 4657 4658-- Was_Hidden (Flag196) 4659-- Defined in all entities. Used to save the value of the Is_Hidden 4660-- attribute when the limited-view is installed (Ada 2005: AI-217). 4661 4662-- Wrapped_Entity (Node27) 4663-- Defined in functions and procedures which have been classified as 4664-- Is_Primitive_Wrapper. Set to the entity being wrapper. 4665 4666--------------------------- 4667-- Renaming and Aliasing -- 4668--------------------------- 4669 4670-- Several entity attributes relate to renaming constructs, and to the use of 4671-- different names to refer to the same entity. The following is a summary of 4672-- these constructs and their prefered uses. 4673 4674-- There are three related attributes: 4675 4676-- Renamed_Entity 4677-- Renamed_Object 4678-- Alias 4679 4680-- They all overlap because they are supposed to apply to different entity 4681-- kinds. They are semantically related, and have the following intended uses: 4682 4683-- a) Renamed_Entity appplies to entities in renaming declarations that rename 4684-- an entity, so the value of the attribute IS an entity. This applies to 4685-- generic renamings, package renamings, exception renamings, and subprograms 4686-- renamings that rename a subprogram (rather than an attribute, an entry, a 4687-- protected operation, etc). 4688 4689-- b) Alias applies to overloadable entities, and the value is an overloadable 4690-- entity. So this is a subset of the previous one. We use the term Alias to 4691-- cover both renamings and inherited operations, because both cases are 4692-- handled in the same way when expanding a call. Namely the Alias of a given 4693-- subprogram is the subprogram that will actually be called. 4694 4695-- Both a) and b) are set transitively, so that in fact it is not necessary to 4696-- traverse chains of renamings when looking for the original entity: it's 4697-- there in one step (this is done when analyzing renaming declarations other 4698-- than object renamings in sem_ch8). 4699 4700-- c) Renamed_Object applies to constants and variables. Given that the name 4701-- in an object renaming declaration is not necessarily an entity name, the 4702-- value of the attribute is the tree for that name, eg AR (1).Comp. The case 4703-- when that name is in fact an entity is not handled specially. This is why 4704-- in a few cases we need to use a loop to trace a chain of object renamings 4705-- where all of them happen to be entities. So: 4706 4707-- X : integer; 4708-- Y : integer renames X; -- renamed object is the identifier X 4709-- Z : integer renames Y; -- renamed object is the identifier Y 4710 4711-- The front-end does not store explicitly the fact that Z renames X. 4712 4713-------------------------------------- 4714-- Delayed Freezing and Elaboration -- 4715-------------------------------------- 4716 4717-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 4718-- freeze node, which appears later in the expanded tree. 4719 4720-- a) The flag is used by the front-end to trigger expansion actions 4721-- which include the generation of that freeze node. Typically this happens at 4722-- the end of the current compilation unit, or before the first subprogram 4723-- body is encountered in the current unit. See files freeze and exp_ch13 for 4724-- details on the actions triggered by a freeze node, which include the 4725-- construction of initialization procedures and dispatch tables. 4726 4727-- b) The flag is used by the backend to defer elaboration of the entity until 4728-- its freeze node is seen. In the absence of an explicit freeze node, an 4729-- entity is frozen (and elaborated) at the point of declaration. 4730 4731-- For object declarations, the flag is set when an address clause for the 4732-- object is encountered. Legality checks on the address expression only 4733-- take place at the freeze point of the object. 4734 4735-- Most types have an explicit freeze node, because they cannot be elaborated 4736-- until all representation and operational items that apply to them have been 4737-- analyzed. Private types and incomplete types have the flag set as well, as 4738-- do task and protected types. 4739 4740-- Implicit base types created for type derivations, as well as classwide 4741-- types created for all tagged types, have the flag set. 4742 4743-- If a subprogram has an access parameter whose designated type is incomplete 4744-- the subprogram has the flag set. 4745 4746------------------ 4747-- Access Kinds -- 4748------------------ 4749 4750-- The following entity kinds are introduced by the corresponding type 4751-- definitions: 4752 4753-- E_Access_Type, 4754-- E_General_Access_Type, 4755-- E_Access_Subprogram_Type, 4756-- E_Anonymous_Access_Subprogram_Type, 4757-- E_Access_Protected_Subprogram_Type, 4758-- E_Anonymous_Access_Protected_Subprogram_Type 4759-- E_Anonymous_Access_Type. 4760 4761-- E_Access_Subtype is for an access subtype created by a subtype 4762-- declaration. 4763 4764-- In addition, we define the kind E_Allocator_Type to label allocators. 4765-- This is because special resolution rules apply to this construct. 4766-- Eventually the constructs are labeled with the access type imposed by 4767-- the context. The backend should never see types with this Ekind. 4768 4769-- Similarly, the type E_Access_Attribute_Type is used as the initial kind 4770-- associated with an access attribute. After resolution a specific access 4771-- type will be established as determined by the context. 4772 4773-- Finally, the type Any_Access is used to label -null- during type 4774-- resolution. Any_Access is also replaced by the context type after 4775-- resolution. 4776 4777-------------------------------- 4778-- Classification of Entities -- 4779-------------------------------- 4780 4781-- The classification of program entities which follows is a refinement of 4782-- the list given in RM 3.1(1). E.g., separate entities denote subtypes of 4783-- different type classes. Ada 95 entities include class wide types, 4784-- protected types, subprogram types, generalized access types, generic 4785-- formal derived types and generic formal packages. 4786 4787-- The order chosen for these kinds allows us to classify related entities 4788-- so that they are contiguous. As a result, they do not appear in the 4789-- exact same order as their order of first appearance in the LRM (For 4790-- example, private types are listed before packages). The contiguity 4791-- allows us to define useful subtypes (see below) such as type entities, 4792-- overloaded entities, etc. 4793 4794-- Each entity (explicitly or implicitly declared) has a kind, which is 4795-- a value of the following type: 4796 4797 type Entity_Kind is ( 4798 4799 E_Void, 4800 -- The initial Ekind value for a newly created entity. Also used as the 4801 -- Ekind for Standard_Void_Type, a type entity in Standard used as a 4802 -- dummy type for the return type of a procedure (the reason we create 4803 -- this type is to share the circuits for performing overload resolution 4804 -- on calls). 4805 4806 ------------- 4807 -- Objects -- 4808 ------------- 4809 4810 E_Component, 4811 -- Components of a record declaration, private declarations of 4812 -- protected objects. 4813 4814 E_Constant, 4815 -- Constants created by an object declaration with a constant keyword 4816 4817 E_Discriminant, 4818 -- A discriminant, created by the use of a discriminant in a type 4819 -- declaration. 4820 4821 E_Loop_Parameter, 4822 -- A loop parameter created by a for loop 4823 4824 E_Variable, 4825 -- Variables created by an object declaration with no constant keyword 4826 4827 ------------------------ 4828 -- Parameter Entities -- 4829 ------------------------ 4830 4831 -- Parameters are also objects 4832 4833 E_Out_Parameter, 4834 -- An out parameter of a subprogram or entry 4835 4836 E_In_Out_Parameter, 4837 -- An in-out parameter of a subprogram or entry 4838 4839 E_In_Parameter, 4840 -- An in parameter of a subprogram or entry 4841 4842 -------------------------------- 4843 -- Generic Parameter Entities -- 4844 -------------------------------- 4845 4846 -- Generic parameters are also objects 4847 4848 E_Generic_In_Out_Parameter, 4849 -- A generic in out parameter, created by the use of a generic in out 4850 -- parameter in a generic declaration. 4851 4852 E_Generic_In_Parameter, 4853 -- A generic in parameter, created by the use of a generic in 4854 -- parameter in a generic declaration. 4855 4856 ------------------- 4857 -- Named Numbers -- 4858 ------------------- 4859 4860 E_Named_Integer, 4861 -- Named numbers created by a number declaration with an integer value 4862 4863 E_Named_Real, 4864 -- Named numbers created by a number declaration with a real value 4865 4866 ----------------------- 4867 -- Enumeration Types -- 4868 ----------------------- 4869 4870 E_Enumeration_Type, 4871 -- Enumeration types, created by an enumeration type declaration 4872 4873 E_Enumeration_Subtype, 4874 -- Enumeration subtypes, created by an explicit or implicit subtype 4875 -- declaration applied to an enumeration type or subtype. 4876 4877 ------------------- 4878 -- Numeric Types -- 4879 ------------------- 4880 4881 E_Signed_Integer_Type, 4882 -- Signed integer type, used for the anonymous base type of the 4883 -- integer subtype created by an integer type declaration. 4884 4885 E_Signed_Integer_Subtype, 4886 -- Signed integer subtype, created by either an integer subtype or 4887 -- integer type declaration (in the latter case an integer type is 4888 -- created for the base type, and this is the first named subtype). 4889 4890 E_Modular_Integer_Type, 4891 -- Modular integer type, used for the anonymous base type of the 4892 -- integer subtype created by a modular integer type declaration. 4893 4894 E_Modular_Integer_Subtype, 4895 -- Modular integer subtype, created by either an modular subtype 4896 -- or modular type declaration (in the latter case a modular type 4897 -- is created for the base type, and this is the first named subtype). 4898 4899 E_Ordinary_Fixed_Point_Type, 4900 -- Ordinary fixed type, used for the anonymous base type of the fixed 4901 -- subtype created by an ordinary fixed point type declaration. 4902 4903 E_Ordinary_Fixed_Point_Subtype, 4904 -- Ordinary fixed point subtype, created by either an ordinary fixed 4905 -- point subtype or ordinary fixed point type declaration (in the 4906 -- latter case a fixed point type is created for the base type, and 4907 -- this is the first named subtype). 4908 4909 E_Decimal_Fixed_Point_Type, 4910 -- Decimal fixed type, used for the anonymous base type of the decimal 4911 -- fixed subtype created by an ordinary fixed point type declaration. 4912 4913 E_Decimal_Fixed_Point_Subtype, 4914 -- Decimal fixed point subtype, created by either a decimal fixed point 4915 -- subtype or decimal fixed point type declaration (in the latter case 4916 -- a fixed point type is created for the base type, and this is the 4917 -- first named subtype). 4918 4919 E_Floating_Point_Type, 4920 -- Floating point type, used for the anonymous base type of the 4921 -- floating point subtype created by a floating point type declaration. 4922 4923 E_Floating_Point_Subtype, 4924 4925 -- Floating point subtype, created by either a floating point subtype 4926 -- or floating point type declaration (in the latter case a floating 4927 -- point type is created for the base type, and this is the first 4928 -- named subtype). 4929 4930 ------------------ 4931 -- Access Types -- 4932 ------------------ 4933 4934 E_Access_Type, 4935 -- An access type created by an access type declaration with no all 4936 -- keyword present. Note that the predefined type Any_Access, which 4937 -- has E_Access_Type Ekind, is used to label NULL in the upwards pass 4938 -- of type analysis, to be replaced by the true access type in the 4939 -- downwards resolution pass. 4940 4941 E_Access_Subtype, 4942 -- An access subtype created by a subtype declaration for any access 4943 -- type (whether or not it is a general access type). 4944 4945 E_Access_Attribute_Type, 4946 -- An access type created for an access attribute (one of 'Access, 4947 -- 'Unrestricted_Access, or Unchecked_Access). 4948 4949 E_Allocator_Type, 4950 -- A special internal type used to label allocators and references to 4951 -- objects using 'Reference.

Meanwhile, the access 6815 -- procedures in the body of Einfo permit many, but not all, attributes 6816 -- to be applied to an E_Void entity, precisely so that this kind of 6817 -- pre-setting of attributes works.

Of course, from the point of view of a user of this 6854 -- package, the distinction is not visible (even the field information 6855 -- provided below should be disregarded, as it is subject to change 6856 -- without notice). A number of attributes appear as lists: lists of 6857 -- formals, lists of actuals, of discriminants, etc. For these, pairs 6858 -- of functions are defined, which take the form: 6859 6860 -- function First_Thing (E : Enclosing_Construct) return Thing; 6861 -- function Next_Thing (T : Thing) return Thing; 6862 6863 -- The end of iteration is always signaled by a value of Empty, so that 6864 -- loops over these chains invariably have the form: 6865 6866 -- This : Thing; 6867 -- ... 6868 -- This := First_Thing (E); 6869 6870 -- while Present (This) loop 6871 -- Do_Something_With (This); 6872 -- ... 6873 -- This := Next_Thing (This); 6874 -- end loop; 6875 6876 ----------------------------------- 6877 -- Handling of Check Suppression -- 6878 ----------------------------------- 6879 6880 -- There are three ways that checks can be suppressed: 6881 6882 -- 1. At the command line level 6883 -- 2. At the scope level. 6884 -- 3. At the entity level. 6885 6886 -- See spec of Sem in sem.ads for details of the data structures used 6887 -- to keep track of these various methods for suppressing checks. 6888 6889 ------------------------------- 6890 -- Handling of Discriminants -- 6891 ------------------------------- 6892 6893 -- During semantic processing, discriminants are separate entities which 6894 -- reflect the semantic properties and allowed usage of discriminants in 6895 -- the language. 6896 6897 -- In the case of discriminants used as bounds, the references are handled 6898 -- directly, since special processing is needed in any case. However, there 6899 -- are two circumstances in which discriminants are referenced in a quite 6900 -- general manner, like any other variables: 6901 6902 -- In initialization expressions for records. Note that the expressions 6903 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline 6904 -- pragmas are effectively in this category, since these pragmas are 6905 -- converted to initialized record fields in the Corresponding_Record_ 6906 -- Type. 6907 6908 -- In task and protected bodies, where the discriminant values may be 6909 -- referenced freely within these bodies. Discriminants can also appear 6910 -- in bounds of entry families and in defaults of operations. 6911 6912 -- In both these cases, the discriminants must be treated essentially as 6913 -- objects. The following approach is used to simplify and minimize the 6914 -- special processing that is required. 6915 6916 -- When a record type with discriminants is analyzed, semantic processing 6917 -- creates the entities for the discriminants. It also creates additional 6918 -- sets of entities called discriminals, one for each of the discriminants, 6919 -- and the Discriminal field of the discriminant entity points to this 6920 -- additional entity, which is initially created as an uninitialized 6921 -- (E_Void) entity. 6922 6923 -- During expansion of expressions, any discriminant reference is replaced 6924 -- by a reference to the corresponding discriminal. When the initialization 6925 -- procedure for the record is created (there will always be one, since 6926 -- discriminants are present, see Exp_Ch3 for further details), the 6927 -- discriminals are used as the entities for the formal parameters of 6928 -- this initialization procedure. The references to these discriminants 6929 -- have already been replaced by references to these discriminals, which 6930 -- are now the formal parameters corresponding to the required objects. 6931 6932 -- In the case of a task or protected body, the semantics similarly creates 6933 -- a set of discriminals for the discriminants of the task or protected 6934 -- type. When the procedure is created for the task body, the parameter 6935 -- passed in is a reference to the task value type, which contains the 6936 -- required discriminant values. The expander creates a set of declarations 6937 -- of the form: 6938 6939 -- discr_nameD : constant discr_type renames _task.discr_name; 6940 6941 -- where discr_nameD is the discriminal entity referenced by the task 6942 -- discriminant, and _task is the task value passed in as the parameter. 6943 -- Again, any references to discriminants in the task body have been 6944 -- replaced by the discriminal reference, which is now an object that 6945 -- contains the required value. 6946 6947 -- This approach for tasks means that two sets of discriminals are needed 6948 -- for a task type, one for the initialization procedure, and one for the 6949 -- task body. This works out nicely, since the semantics allocates one set 6950 -- for the task itself, and one set for the corresponding record. 6951 6952 -- The one bit of trickiness arises in making sure that the right set of 6953 -- discriminals is used at the right time. First the task definition is 6954 -- processed. Any references to discriminants here are replaced by the 6955 -- corresponding *task* discriminals (the record type doesn't even exist 6956 -- yet, since it is constructed as part of the expansion of the task 6957 -- declaration, which happens after the semantic processing of the task 6958 -- definition). The discriminants to be used for the corresponding record 6959 -- are created at the same time as the other discriminals, and held in the 6960 -- CR_Discriminant field of the discriminant. A use of the discriminant in 6961 -- a bound for an entry family is replaced with the CR_Discriminant because 6962 -- it controls the bound of the entry queue array which is a component of 6963 -- the corresponding record. 6964 6965 -- Just before the record initialization routine is constructed, the 6966 -- expander exchanges the task and record discriminals. This has two 6967 -- effects. First the generation of the record initialization routine 6968 -- uses the discriminals that are now on the record, which is the set 6969 -- that used to be on the task, which is what we want. 6970 6971 -- Second, a new set of (so far unused) discriminals is now on the task 6972 -- discriminants, and it is this set that will be used for expanding the 6973 -- task body, and also for the discriminal declarations at the start of 6974 -- the task body. 6975 6976 --------------------------------------------------- 6977 -- Handling of private data in protected objects -- 6978 --------------------------------------------------- 6979 6980 -- Private components in protected types pose problems similar to those 6981 -- of discriminants. Private data is visible and can be directly referenced 6982 -- from protected bodies. However, when protected entries and subprograms 6983 -- are expanded into corresponding bodies and barrier functions, private 6984 -- components lose their original context and visibility. 6985 6986 -- To remedy this side effect of expansion, private components are expanded 6987 -- into renamings called "privals", by analogy with "discriminals". 6988 6989 -- private_comp : comp_type renames _object.private_comp; 6990 6991 -- Prival declarations are inserted during the analysis of subprogram and 6992 -- entry bodies to ensure proper visibility for any subsequent expansion. 6993 -- _Object is the formal parameter of the generated corresponding body or 6994 -- a local renaming which denotes the protected object obtained from entry 6995 -- parameter _O. Privals receive minimal decoration upon creation and are 6996 -- categorized as either E_Variable for the general case or E_Constant when 6997 -- they appear in functions. 6998 6999 -- Along with the local declarations, each private component carries a 7000 -- placeholder which references the prival entity in the current body. This 7001 -- form of indirection is used to resolve name clashes of privals and other 7002 -- locally visible entities such as parameters, local objects, entry family 7003 -- indexes or identifiers used in the barrier condition. 7004 7005 -- When analyzing the statements of a protected subprogram or entry, any 7006 -- reference to a private component must resolve to the locally declared 7007 -- prival through normal visibility. In case of name conflicts (the cases 7008 -- above), the prival is marked as hidden and acts as a weakly declared 7009 -- entity. As a result, the reference points to the correct entity. When a 7010 -- private component is denoted by an expanded name (prot_type.comp for 7011 -- example), the expansion mechanism uses the placeholder of the component 7012 -- to correct the Entity and Etype of the reference. 7013 7014 ------------------- 7015 -- Type Synonyms -- 7016 ------------------- 7017 7018 -- The following type synonyms are used to tidy up the function and 7019 -- procedure declarations that follow, and also to make it possible to meet 7020 -- the requirement for the XEINFO utility that all function specs must fit 7021 -- on a single source line. 7022 7023 subtype B is Boolean; 7024 subtype C is Component_Alignment_Kind; 7025 subtype E is Entity_Id; 7026 subtype F is Float_Rep_Kind; 7027 subtype M is Mechanism_Type; 7028 subtype N is Node_Id; 7029 subtype U is Uint; 7030 subtype R is Ureal; 7031 subtype L is Elist_Id; 7032 subtype S is List_Id; 7033 7034 -------------------------------- 7035 -- Attribute Access Functions -- 7036 -------------------------------- 7037 7038 -- All attributes are manipulated through a procedural interface.
