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-- The Ada 2020 RM acknowledges it and adopts GNAT's Object_Size attribute 136-- for determining the default size of objects, but stops short of applying 137-- it universally like GNAT. Indeed the notable exceptions are nonaliased 138-- stand-alone objects, which are not covered by Object_Size in Ada 2020. 139 140-- We proceed as follows, for discrete and fixed-point subtypes, we have 141-- two separate sizes for each subtype: 142 143-- The Object_Size, which is used for determining the default size of 144-- objects and components. This size value can be referred to using the 145-- Object_Size attribute. The phrase "is used" here means that it is 146-- the basis of the determination of the size. The back end is free to 147-- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone 148-- character might be stored in 32 bits on a machine with no efficient 149-- byte access instructions such as the Alpha. 150 151-- The default rules for the value of Object_Size are as follows: 152 153-- The Object_Size for base subtypes reflect the natural hardware 154-- size in bits (see Ttypes and Cstand for integer types). For 155-- enumeration and fixed-point base subtypes have 8, 16, 32, or 64 156-- bits for this size, depending on the range of values to be stored. 157 158-- The Object_Size of a subtype is the same as the Object_Size of 159-- the subtype from which it is obtained. 160 161-- The Object_Size of a derived base type is copied from the parent 162-- base type, and the Object_Size of a derived first subtype is copied 163-- from the parent first subtype. 164 165-- The Ada 2020 RM defined attribute Object_Size uses this implementation. 166 167-- The Value_Size, which is the number of bits required to store a value 168-- of the type. This size can be referred to using the Value_Size 169-- attribute. This value is used for determining how tightly to pack 170-- records or arrays with components of this type, and also affects 171-- the semantics of unchecked conversion (unchecked conversions where 172-- the Value_Size values differ generate a warning, and are potentially 173-- target dependent). 174 175-- The default rules for the value of Value_Size are as follows: 176 177-- The Value_Size for a base subtype is the minimum number of bits 178-- required to store all values of the type (including the sign bit 179-- only if negative values are possible). 180 181-- If a subtype statically matches the first subtype, then it has 182-- by default the same Value_Size as the first subtype. This is a 183-- consequence of RM 13.1(14) ("if two subtypes statically match, 184-- then their subtype-specific aspects are the same".) 185 186-- All other subtypes have a Value_Size corresponding to the minimum 187-- number of bits required to store all values of the subtype. For 188-- dynamic bounds, it is assumed that the value can range down or up 189-- to the corresponding bound of the ancestor. 190 191-- The Ada 95 RM defined attribute Size is identified with Value_Size. 192 193-- The Size attribute may be defined for a first-named subtype. This sets 194-- the Value_Size of the first-named subtype to the given value, and the 195-- Object_Size of this first-named subtype to the given value padded up 196-- to an appropriate boundary. It is a consequence of the default rules 197-- above that this Object_Size will apply to all further subtypes. On the 198-- other hand, Value_Size is affected only for the first subtype, any 199-- dynamic subtypes obtained from it directly, and any statically matching 200-- subtypes. The Value_Size of any other static subtypes is not affected. 201 202-- Value_Size and Object_Size may be explicitly set for any subtype using 203-- an attribute definition clause. Note that the use of such a clause can 204-- cause the RM 13.1(14) rule to be violated, in Ada 95 and 2020 for the 205-- Value_Size attribute, but only in Ada 95 for the Object_Size attribute. 206-- If access types reference aliased objects whose subtypes have differing 207-- Object_Size values as a result of explicit attribute definition clauses, 208-- then it is erroneous to convert from one access subtype to the other. 209 210-- At the implementation level, the Esize field stores the Object_Size 211-- and the RM_Size field stores the Value_Size (hence the value of the 212-- Size attribute, which, as noted above, is equivalent to Value_Size). 213 214-- To get a feel for the difference, consider the following examples (note 215-- that in each case the base is short_short_integer with a size of 8): 216 217-- Object_Size Value_Size 218 219-- type x1 is range 0..5; 8 3 220 221-- type x2 is range 0..5; 222-- for x2'size use 12; 16 12 223 224-- subtype x3 is x2 range 0 .. 3; 16 2 225 226-- subtype x4 is x2'base range 0 .. 10; 8 4 227 228-- dynamic : x2'Base range -64 .. +63; 229 230-- subtype x5 is x2 range 0 .. dynamic; 16 3* 231 232-- subtype x6 is x2'base range 0 .. dynamic; 8 7* 233 234-- Note: the entries marked * are not actually specified by the Ada 95 RM, 235-- but it seems in the spirit of the RM rules to allocate the minimum number 236-- of bits known to be large enough to hold the given range of values. 237 238-- So far, so good, but GNAT has to obey the RM rules, so the question is 239-- under what conditions must the RM Size be used. The following is a list 240-- of the occasions on which the RM Size must be used: 241 242-- Component size for packed arrays or records 243-- Value of the attribute Size for a type 244-- Warning about sizes not matching for unchecked conversion 245 246-- The RM_Size field keeps track of the RM Size as needed in these 247-- three situations. 248 249-- For elementary types other than discrete and fixed-point types, the 250-- Object_Size and Value_Size are the same (and equivalent to the RM 251-- attribute Size). Only Size may be specified for such types. 252 253-- For composite types, Object_Size and Value_Size are computed from their 254-- respective value for the type of each element as well as the layout. 255 256-- All size attributes are stored as Uint values. Negative values are used to 257-- reference GCC expressions for the case of non-static sizes, as explained 258-- in Repinfo. 259 260-------------------------------------- 261-- Delayed Freezing and Elaboration -- 262-------------------------------------- 263 264-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 265-- freeze node, which appears later in the expanded tree. 266 267-- a) The flag is used by the front-end to trigger expansion actions which 268-- include the generation of that freeze node. Typically this happens at the 269-- end of the current compilation unit, or before the first subprogram body is 270-- encountered in the current unit. See files freeze and exp_ch13 for details 271-- on the actions triggered by a freeze node, which include the construction 272-- of initialization procedures and dispatch tables. 273 274-- b) The presence of a freeze node on an entity is used by the backend to 275-- defer elaboration of the entity until its freeze node is seen. In the 276-- absence of an explicit freeze node, an entity is frozen (and elaborated) 277-- at the point of declaration. 278 279-- For object declarations, the flag is set when an address clause for the 280-- object is encountered. Legality checks on the address expression only take 281-- place at the freeze point of the object. 282 283-- Most types have an explicit freeze node, because they cannot be elaborated 284-- until all representation and operational items that apply to them have been 285-- analyzed. Private types and incomplete types have the flag set as well, as 286-- do task and protected types. 287 288-- Implicit base types created for type derivations, as well as classwide 289-- types created for all tagged types, have the flag set. 290 291-- If a subprogram has an access parameter whose designated type is incomplete 292-- the subprogram has the flag set. 293 294----------------------- 295-- Entity Attributes -- 296----------------------- 297 298-- This section contains a complete list of the attributes that are defined 299-- on entities. Some attributes apply to all entities, others only to certain 300-- kinds of entities. In the latter case the attribute should only be set or 301-- accessed if the Ekind field indicates an appropriate entity. 302 303-- There are two kinds of attributes that apply to entities, stored and 304-- synthesized. Stored attributes correspond to a field or flag in the entity 305-- itself. Such attributes are identified in the table below by giving the 306-- field or flag in the attribute that is used to hold the attribute value. 307-- Synthesized attributes are not stored directly, but are rather computed as 308-- needed from other attributes, or from information in the tree. These are 309-- marked "synthesized" in the table below. The stored attributes have both 310-- access functions and set procedures to set the corresponding values, while 311-- synthesized attributes have only access functions. 312 313-- Note: in the case of Node, Uint, or Elist fields, there are cases where the 314-- same physical field is used for different purposes in different entities, 315-- so these access functions should only be referenced for the class of 316-- entities in which they are defined as being present. Flags are not 317-- overlapped in this way, but nevertheless as a matter of style and 318-- abstraction (which may or may not be checked by assertions in the 319-- body), this restriction should be observed for flag fields as well. 320 321-- Note: certain of the attributes on types apply only to base types, and 322-- are so noted by the notation [base type only]. These are cases where the 323-- attribute of any subtype is the same as the attribute of the base type. 324-- The attribute can be referenced on a subtype (and automatically retrieves 325-- the value from the base type). However, it is an error to try to set the 326-- attribute on other than the base type, and if assertions are enabled, 327-- an attempt to set the attribute on a subtype will raise an assert error. 328 329-- Other attributes are noted as applying to the [implementation base type 330-- only]. These are representation attributes which must always apply to a 331-- full non-private type, and where the attributes are always on the full 332-- type. The attribute can be referenced on a subtype (and automatically 333-- retrieves the value from the implementation base type). However, it is an 334-- error to try to set the attribute on other than the implementation base 335-- type, and if assertions are enabled, an attempt to set the attribute on a 336-- subtype will raise an assert error. 337 338-- Abstract_States (Elist25) 339-- Defined for E_Package entities. Contains a list of all the abstract 340-- states declared by the related package. 341 342-- Accept_Address (Elist21) 343-- Defined in entries. If an accept has a statement sequence, then an 344-- address variable is created, which is used to hold the address of the 345-- parameters, as passed by the runtime. Accept_Address holds an element 346-- list which represents a stack of entities for these address variables. 347-- The current entry is the top of the stack, which is the last element 348-- on the list. A stack is required to handle the case of nested select 349-- statements referencing the same entry. 350 351-- Access_Disp_Table (Elist16) [implementation base type only] 352-- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged 353-- types to point to their dispatch tables. The first two entities are 354-- associated with the primary dispatch table: 1) primary dispatch table 355-- with user-defined primitives 2) primary dispatch table with predefined 356-- primitives. For each interface type covered by the tagged type we also 357-- have: 3) secondary dispatch table with thunks of primitives covering 358-- user-defined interface primitives, 4) secondary dispatch table with 359-- thunks of predefined primitives, 5) secondary dispatch table with user 360-- defined primitives, and 6) secondary dispatch table with predefined 361-- primitives. The last entity of this list is an access type declaration 362-- used to expand dispatching calls through the primary dispatch table. 363-- For an untagged record, contains No_Elist. 364 365-- Access_Disp_Table_Elab_Flag (Node30) [implementation base type only] 366-- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged 367-- types whose dispatch table elaboration must be completed at run time 368-- by the IP routine to point to its pending elaboration flag entity. 369-- This flag is needed when the elaboration of the dispatch table relies 370-- on attribute 'Position applied to an object of the type; it is used by 371-- the IP routine to avoid performing this elaboration twice. 372 373-- Activation_Record_Component (Node31) 374-- Defined for E_Variable, E_Constant, E_Loop_Parameter, and formal 375-- parameter entities. Used in Opt.Unnest_Subprogram_Mode, in which case 376-- a reference to an uplevel entity produces a corresponding component 377-- in the generated ARECnT activation record (Exp_Unst for details). 378 379-- Actual_Subtype (Node17) 380-- Defined in variables, constants, and formal parameters. This is the 381-- subtype imposed by the value of the object, as opposed to its nominal 382-- subtype, which is imposed by the declaration. The actual subtype 383-- differs from the nominal one when the latter is indefinite (as in the 384-- case of an unconstrained formal parameter, or a variable declared 385-- with an unconstrained type and an initial value). The nominal subtype 386-- is the Etype entry for the entity. The Actual_Subtype field is set 387-- only if the actual subtype differs from the nominal subtype. If the 388-- actual and nominal subtypes are the same, then the Actual_Subtype 389-- field is Empty, and Etype indicates both types. 390-- 391-- For objects, the Actual_Subtype is set only if this is a discriminated 392-- type. For arrays, the bounds of the expression are obtained and the 393-- Etype of the object is directly the constrained subtype. This is 394-- rather irregular, and the semantic checks that depend on the nominal 395-- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv). 396 397-- Address_Clause (synthesized) 398-- Applies to entries, objects and subprograms. Set if an address clause 399-- is present which references the object or subprogram and points to 400-- the N_Attribute_Definition_Clause node. Empty if no Address clause. 401-- The expression in the address clause is always a constant that is 402-- defined before the entity to which the address clause applies. 403-- Note: The backend references this field in E_Task_Type entities??? 404 405-- Address_Taken (Flag104) 406-- Defined in all entities. Set if the Address or Unrestricted_Access 407-- attribute is applied directly to the entity, i.e. the entity is the 408-- entity of the prefix of the attribute reference. Also set if the 409-- entity is the second argument of an Asm_Input or Asm_Output attribute, 410-- as the construct may entail taking its address. And also set if the 411-- entity is a subprogram and the Access or Unchecked_Access attribute is 412-- applied. Used by the backend to make sure that the address can be 413-- meaningfully taken, and also in the case of subprograms to control 414-- output of certain warnings. 415 416-- Aft_Value (synthesized) 417-- Applies to fixed and decimal types. Computes a universal integer that 418-- holds value of the Aft attribute for the type. 419 420-- Alias (Node18) 421-- Defined in overloadable entities (literals, subprograms, entries) and 422-- subprograms that cover a primitive operation of an abstract interface 423-- (that is, subprograms with the Interface_Alias attribute). In case of 424-- overloaded entities it points to the parent subprogram of a derived 425-- subprogram. In case of abstract interface subprograms it points to the 426-- subprogram that covers the abstract interface primitive. Also used for 427-- a subprogram renaming, where it points to the renamed subprogram. For 428-- an inherited operation (of a type extension) that is overridden in a 429-- private part, the Alias is the overriding operation. In this fashion a 430-- call from outside the package ends up executing the new body even if 431-- non-dispatching, and a call from inside calls the overriding operation 432-- because it hides the implicit one. Alias is always empty for entries. 433 434-- Alignment (Uint14) 435-- Defined in entities for types and also in constants, variables 436-- (including exceptions where it refers to the static data allocated for 437-- an exception), loop parameters, and formal parameters. This indicates 438-- the desired alignment for a type, or the actual alignment for an 439-- object. A value of zero (Uint_0) indicates that the alignment has not 440-- been set yet. The alignment can be set by an explicit alignment 441-- clause, or set by the front-end in package Layout, or set by the 442-- back-end as part of the back-end back-annotation process. The 443-- alignment field is also defined in E_Exception entities, but there it 444-- is used only by the back-end for back annotation. 445 446-- Alignment_Clause (synthesized) 447-- Applies to all entities for types and objects. If an alignment 448-- attribute definition clause is present for the entity, then this 449-- function returns the N_Attribute_Definition clause that specifies the 450-- alignment. If no alignment clause applies to the type, then the call 451-- to this function returns Empty. Note that the call can return a 452-- non-Empty value even if Has_Alignment_Clause is not set (happens with 453-- subtype and derived type declarations). Note also that a record 454-- definition clause with an (obsolescent) mod clause is converted 455-- into an attribute definition clause for this purpose. 456 457-- Anonymous_Designated_Type (Node35) 458-- Defined in variables which represent anonymous finalization masters. 459-- Contains the designated type which is being serviced by the master. 460 461-- Anonymous_Masters (Elist29) 462-- Defined in packages, subprograms, and subprogram bodies. Contains a 463-- list of anonymous finalization masters declared within the related 464-- unit. The list acts as a mapping between a master and a designated 465-- type. 466 467-- Anonymous_Object (Node30) 468-- Present in protected and task type entities. Contains the entity of 469-- the anonymous object created for a single protected or task type. 470 471-- Associated_Entity (Node37) 472-- Defined in all entities. This field is similar to Associated_Node, but 473-- applied to entities. The attribute links an entity from the generic 474-- template with its corresponding entity in the analyzed generic copy. 475-- The global references mechanism relies on the Associated_Entity to 476-- infer the context. 477 478-- Associated_Formal_Package (Node12) 479-- Defined in packages that are the actuals of formal_packages. Points 480-- to the entity in the declaration for the formal package. 481 482-- Associated_Node_For_Itype (Node8) 483-- Defined in all type and subtype entities. Set non-Empty only for 484-- Itypes. Set to point to the associated node for the Itype, i.e. 485-- the node whose elaboration generated the Itype. This is used for 486-- copying trees, to determine whether or not to copy an Itype, and 487-- also for accessibility checks on anonymous access types. This 488-- node is typically an object declaration, component declaration, 489-- type or subtype declaration. 490 491-- For an access discriminant in a type declaration, the associated_ 492-- node_for_itype is the corresponding discriminant specification. 493 494-- For an access parameter it is the enclosing subprogram declaration. 495 496-- For an access_to_protected_subprogram parameter it is the declaration 497-- of the corresponding formal parameter. 498-- 499-- Itypes have no explicit declaration, and therefore are not attached to 500-- the tree: their Parent field is always empty. The Associated_Node_For_ 501-- Itype is the only way to determine the construct that leads to the 502-- creation of a given itype entity. 503 504-- Associated_Storage_Pool (Node22) [root type only] 505-- Defined in simple and general access type entities. References the 506-- storage pool to be used for the corresponding collection. A value of 507-- Empty means that the default pool is to be used. This is defined 508-- only in the root type, since derived types must have the same pool 509-- as the parent type. 510 511-- Barrier_Function (Node12) 512-- Defined in protected entries and entry families. This is the 513-- subprogram declaration for the body of the function that returns 514-- the value of the entry barrier. 515 516-- Base_Type (synthesized) 517-- Applies to all type and subtype entities. Returns the base type of a 518-- type or subtype. The base type of a type is the type itself. The base 519-- type of a subtype is the type that it constrains (which is always 520-- a type entity, not some other subtype). Note that in the case of a 521-- subtype of a private type, it is possible for the base type attribute 522-- to return a private type, even if the subtype to which it applies is 523-- non-private. See also Implementation_Base_Type. Note: it is allowed to 524-- apply Base_Type to other than a type, in which case it simply returns 525-- the entity unchanged. 526 527-- Block_Node (Node11) 528-- Defined in block entities. Points to the identifier in the 529-- Block_Statement itself. Used when retrieving the block construct 530-- for finalization purposes, The block entity has an implicit label 531-- declaration in the enclosing declarative part, and has otherwise 532-- no direct connection in the tree with the block statement. The 533-- link is to the identifier (which is an occurrence of the entity) 534-- and not to the block_statement itself, because the statement may 535-- be rewritten, e.g. in the process of removing dead code. 536 537-- Body_Entity (Node19) 538-- Defined in package and generic package entities, points to the 539-- corresponding package body entity if one is present. 540 541-- Body_Needed_For_SAL (Flag40) 542-- Defined in package and subprogram entities that are compilation 543-- units. Indicates that the source for the body must be included 544-- when the unit is part of a standalone library. 545 546-- Body_Needed_For_Inlining (Flag299) 547-- Defined in package entities that are compilation units. Used to 548-- determine whether the body unit needs to be compiled when the 549-- package declaration appears in the list of units to inline. A body 550-- is needed for inline processing if the unit declaration contains 551-- functions that carry pragma Inline or Inline_Always, or if it 552-- contains a generic unit that requires a body. 553-- 554-- Body_References (Elist16) 555-- Defined in abstract state entities. Contains an element list of 556-- references (identifiers) that appear in a package body whose spec 557-- defines the related state. If the body refines the said state, all 558-- references on this list are illegal due to the visible refinement. 559 560-- BIP_Initialization_Call (Node29) 561-- Defined in constants and variables whose corresponding declaration 562-- is wrapped in a transient block and the inital value is provided by 563-- a build-in-place function call. Contains the relocated build-in-place 564-- call after the expansion has decoupled the call from the object. This 565-- attribute is used by the finalization machinery to insert cleanup code 566-- for all additional transient objects found in the transient block. 567 568-- C_Pass_By_Copy (Flag125) [implementation base type only] 569-- Defined in record types. Set if a pragma Convention for the record 570-- type specifies convention C_Pass_By_Copy. This convention name is 571-- treated as identical in all respects to convention C, except that 572-- if it is specified for a record type, then the C_Pass_By_Copy flag 573-- is set, and if a foreign convention subprogram has a formal of the 574-- corresponding type, then the parameter passing mechanism will be 575-- set to By_Copy (unless specifically overridden by an Import or 576-- Export pragma). 577 578-- Can_Never_Be_Null (Flag38) 579-- This flag is defined in all entities. It is set in an object which can 580-- never have a null value. Set for constant access values initialized to 581-- a non-null value. This is also set for all access parameters in Ada 83 582-- and Ada 95 modes, and for access parameters that explicitly exclude 583-- exclude null in Ada 2005 mode. 584-- 585-- This is used to avoid unnecessary resetting of the Is_Known_Non_Null 586-- flag for such entities. In Ada 2005 mode, this is also used when 587-- determining subtype conformance of subprogram profiles to ensure 588-- that two formals have the same null-exclusion status. 589-- 590-- This is also set on some access types, e.g. the Etype of the anonymous 591-- access type of a controlling formal. 592 593-- Can_Use_Internal_Rep (Flag229) [base type only] 594-- Defined in Access_Subprogram_Kind nodes. This flag is set by the 595-- front end and used by the backend. False means that the backend 596-- must represent the type in the same way as Convention-C types (and 597-- other foreign-convention types). On many targets, this means that 598-- the backend will use dynamically generated trampolines for nested 599-- subprograms. True means that the backend can represent the type in 600-- some internal way. On the aforementioned targets, this means that the 601-- backend will not use dynamically generated trampolines. This flag 602-- must be False if Has_Foreign_Convention is True; otherwise, the front 603-- end is free to set the policy. 604-- 605-- Setting this False in all cases corresponds to the traditional back 606-- end strategy, where all access-to-subprogram types are represented the 607-- same way, independent of the Convention. For further details, see also 608-- Always_Compatible_Rep in Targparm. 609-- 610-- Efficiency note: On targets that use dynamically generated 611-- trampolines, False generally favors efficiency of top-level 612-- subprograms, whereas True generally favors efficiency of nested 613-- ones. On other targets, this flag has little or no effect on 614-- efficiency. The front end should take this into account. In 615-- particular, pragma Favor_Top_Level gives a hint that the flag 616-- should be False. 617-- 618-- Note: We considered using Convention-C for this purpose, but we need 619-- this separate flag, because Convention-C implies that in the case of 620-- P'[Unrestricted_]Access, P also have convention C. Sometimes we want 621-- to have Can_Use_Internal_Rep False for an access type, but allow P to 622-- have convention Ada. 623 624-- Chars (Name1) 625-- Defined in all entities. This field contains an entry into the names 626-- table that has the character string of the identifier, character 627-- literal or operator symbol. See Namet for further details. Note that 628-- throughout the processing of the front end, this name is the simple 629-- unqualified name. However, just before the backend is called, a call 630-- is made to Qualify_All_Entity_Names. This causes entity names to be 631-- qualified using the encoding described in exp_dbug.ads, and from that 632-- point (including post backend steps, e.g. cross-reference generation), 633-- the entities will contain the encoded qualified names. 634 635-- Checks_May_Be_Suppressed (Flag31) 636-- Defined in all entities. Set if a pragma Suppress or Unsuppress 637-- mentions the entity specifically in the second argument. If this 638-- flag is set the Global_Entity_Suppress and Local_Entity_Suppress 639-- tables must be consulted to determine if there actually is an active 640-- Suppress or Unsuppress pragma that applies to the entity. 641 642-- Class_Wide_Clone (Node38) 643-- Defined on subprogram entities. Set if the subprogram has a class-wide 644-- ore- or postcondition, and the expression contains calls to other 645-- primitive funtions of the type. Used to implement properly the 646-- semantics of inherited operations whose class-wide condition may 647-- be different from that of the ancestor (See AI012-0195). 648 649-- Class_Wide_Type (Node9) 650-- Defined in all type entities. For a tagged type or subtype, returns 651-- the corresponding implicitly declared class-wide type. For a 652-- class-wide type, returns itself. Set to Empty for untagged types. 653 654-- Cloned_Subtype (Node16) 655-- Defined in E_Record_Subtype and E_Class_Wide_Subtype entities. 656-- Each such entity can either have a Discriminant_Constraint, in 657-- which case it represents a distinct type from the base type (and 658-- will have a list of components and discriminants in the list headed by 659-- First_Entity) or else no such constraint, in which case it will be a 660-- copy of the base type. 661-- 662-- o Each element of the list in First_Entity is copied from the base 663-- type; in that case, this field is Empty. 664-- 665-- o The list in First_Entity is shared with the base type; in that 666-- case, this field points to that entity. 667-- 668-- A record or classwide subtype may also be a copy of some other 669-- subtype and share the entities in the First_Entity with that subtype. 670-- In that case, this field points to that subtype. 671-- 672-- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides 673-- this field. Note that this field ONLY appears in subtype entities, not 674-- in type entities, it is not defined, and it is an error to reference 675-- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity. 676 677-- Comes_From_Source 678-- This flag appears on all nodes, including entities, and indicates 679-- that the node was created by the scanner or parser from the original 680-- source. Thus for entities, it indicates that the entity is defined 681-- in the original source program. 682 683-- Component_Alignment (special field) [base type only] 684-- Defined in array and record entities. Contains a value of type 685-- Component_Alignment_Kind indicating the alignment of components. 686-- Set to Calign_Default normally, but can be overridden by use of 687-- the Component_Alignment pragma. Note: this field is currently 688-- stored in a non-standard way, see body for details. 689 690-- Component_Bit_Offset (Uint11) 691-- Defined in record components (E_Component, E_Discriminant). First 692-- bit position of given component, computed from the first bit and 693-- position values given in the component clause. A value of No_Uint 694-- means that the value is not yet known. The value can be set by the 695-- appearance of an explicit component clause in a record representation 696-- clause, or it can be set by the front-end in package Layout, or it can 697-- be set by the backend. By the time backend processing is completed, 698-- this field is always set. A negative value is used to represent 699-- a value which is not known at compile time, and must be computed 700-- at run-time (this happens if fields of a record have variable 701-- lengths). See package Layout for details of these values. 702-- 703-- Note: Component_Bit_Offset is redundant with respect to the fields 704-- Normalized_First_Bit and Normalized_Position, and could in principle 705-- be eliminated, but it is convenient in several situations, including 706-- use in the backend, to have this redundant field. 707 708-- Component_Clause (Node13) 709-- Defined in record components and discriminants. If a record 710-- representation clause is present for the corresponding record type a 711-- that specifies a position for the component, then the Component_Clause 712-- field of the E_Component entity points to the N_Component_Clause node. 713-- Set to Empty if no record representation clause was present, or if 714-- there was no specification for this component. 715 716-- Component_Size (Uint22) [implementation base type only] 717-- Defined in array types. It contains the component size value for 718-- the array. A value of No_Uint means that the value is not yet set. 719-- The value can be set by the use of a component size clause, or 720-- by the front end in package Layout, or by the backend. A negative 721-- value is used to represent a value which is not known at compile 722-- time, and must be computed at run-time (this happens if the type 723-- of the component has a variable length size). See package Layout 724-- for details of these values. 725 726-- Component_Type (Node20) [implementation base type only] 727-- Defined in array types and string types. References component type. 728 729-- Contains_Ignored_Ghost_Code (Flag279) 730-- Defined in blocks, packages and their bodies, subprograms and their 731-- bodies. Set if the entity contains any ignored Ghost code in the form 732-- of declaration, procedure call, assignment statement or pragma. 733 734-- Contract (Node34) 735-- Defined in constant, entry, entry family, operator, [generic] package, 736-- package body, protected type, [generic] subprogram, subprogram body, 737-- variable and task type entities. Points to the contract of the entity, 738-- holding various assertion items and data classifiers. 739 740-- Contract_Wrapper (Node25) 741-- Defined in entry and entry family entities. Set only when the entry 742-- [family] has contract cases, preconditions, and/or postconditions. 743-- Contains the entity of a wrapper procedure which encapsulates the 744-- original entry and implements precondition/postcondition semantics. 745 746-- Corresponding_Concurrent_Type (Node18) 747-- Defined in record types that are constructed by the expander to 748-- represent task and protected types (Is_Concurrent_Record_Type flag 749-- set). Points to the entity for the corresponding task type or the 750-- protected type. 751 752-- Corresponding_Discriminant (Node19) 753-- Defined in discriminants of a derived type, when the discriminant is 754-- used to constrain a discriminant of the parent type. Points to the 755-- corresponding discriminant in the parent type. Otherwise it is Empty. 756 757-- Corresponding_Equality (Node30) 758-- Defined in function entities for implicit inequality operators. 759-- Denotes the explicit or derived equality operation that creates 760-- the implicit inequality. Note that this field is not present in 761-- other function entities, only in implicit inequality routines, 762-- where Comes_From_Source is always False. 763 764-- Corresponding_Function (Node32) 765-- Defined on procedures internally built with an extra out parameter 766-- to return a constrained array type, when Modify_Tree_For_C is set. 767-- Denotes the function that returns the constrained array type for 768-- which this procedure was built. 769 770-- Corresponding_Procedure (Node32) 771-- Defined on functions that return a constrained array type, when 772-- Modify_Tree_For_C is set. Denotes the internally built procedure 773-- with an extra out parameter created for it. 774 775-- Corresponding_Protected_Entry (Node18) 776-- Defined in subprogram bodies. Set for subprogram bodies that implement 777-- a protected type entry to point to the entity for the entry. 778 779-- Corresponding_Record_Component (Node21) 780-- Defined in components of a derived untagged record type, including 781-- discriminants. For a regular component or a girder discriminant, 782-- points to the corresponding component in the parent type. Set to 783-- Empty for a non-girder discriminant. It is used by the back end to 784-- ensure the layout of the derived type matches that of the parent 785-- type when there is no representation clause on the derived type. 786 787-- Corresponding_Record_Type (Node18) 788-- Defined in protected and task types and subtypes. References the 789-- entity for the corresponding record type constructed by the expander 790-- (see Exp_Ch9). This type is used to represent values of the task type. 791 792-- Corresponding_Remote_Type (Node22) 793-- Defined in record types that describe the fat pointer structure for 794-- Remote_Access_To_Subprogram types. References the original access 795-- to subprogram type. 796 797-- CR_Discriminant (Node23) 798-- Defined in discriminants of concurrent types. Denotes the homologous 799-- discriminant of the corresponding record type. The CR_Discriminant is 800-- created at the same time as the discriminal, and used to replace 801-- occurrences of the discriminant within the type declaration. 802 803-- Current_Use_Clause (Node27) 804-- Defined in packages and in types. For packages, denotes the use 805-- package clause currently in scope that makes the package use_visible. 806-- For types, it denotes the use_type clause that makes the operators of 807-- the type visible. Used for more precise warning messages on redundant 808-- use clauses. 809 810-- Current_Value (Node9) 811-- Defined in all object entities. Set in E_Variable, E_Constant, formal 812-- parameters and E_Loop_Parameter entities if we have trackable current 813-- values. Set non-Empty if the (constant) current value of the variable 814-- is known, This value is valid only for references from the same 815-- sequential scope as the entity. The sequential scope of an entity 816-- includes the immediate scope and any contained scopes that are package 817-- specs, package bodies, blocks (at any nesting level) or statement 818-- sequences in IF or loop statements. 819-- 820-- Another related use of this field is to record information about the 821-- value obtained from an IF or WHILE statement condition. If the IF or 822-- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ", 823-- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a 824-- Current_Value field, RELOP is one of the six relational operators, and 825-- VAL is a compile-time known value then the Current_Value field of OBJ 826-- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node 827-- of the relevant construct, and the Condition field of this can be 828-- consulted to give information about the value of OBJ. For more details 829-- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition. 830 831-- Debug_Info_Off (Flag166) 832-- Defined in all entities. Set if a pragma Suppress_Debug_Info applies 833-- to the entity, or if internal processing in the compiler determines 834-- that suppression of debug information is desirable. Note that this 835-- flag is only for use by the front end as part of the processing for 836-- determining if Needs_Debug_Info should be set. The backend should 837-- always test Needs_Debug_Info, it should never test Debug_Info_Off. 838 839-- Debug_Renaming_Link (Node25) 840-- Used to link the variable associated with a debug renaming declaration 841-- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for 842-- details of the use of this field. 843 844-- Declaration_Node (synthesized) 845-- Applies to all entities. Returns the tree node for the construct that 846-- declared the entity. Normally this is just the Parent of the entity. 847-- One exception arises with child units, where the parent of the entity 848-- is a selected component/defining program unit name. Another exception 849-- is that if the entity is an incomplete type that has been completed or 850-- a private type, then we obtain the declaration node denoted by the 851-- full type, i.e. the full type declaration node. Also note that for 852-- subprograms, this returns the {function,procedure}_specification, not 853-- the subprogram_declaration. 854 855-- Default_Aspect_Component_Value (Node19) [base type only] 856-- Defined in array types. Holds the static value specified in a 857-- Default_Component_Value aspect specification for the array type, 858-- or inherited on derivation. 859 860-- Default_Aspect_Value (Node19) [base type only] 861-- Defined in scalar types. Holds the static value specified in a 862-- Default_Value aspect specification for the type, or inherited 863-- on derivation. 864 865-- Default_Expr_Function (Node21) 866-- Defined in parameters. It holds the entity of the parameterless 867-- function that is built to evaluate the default expression if it is 868-- more complex than a simple identifier or literal. For the latter 869-- simple cases or if there is no default value, this field is Empty. 870 871-- Default_Expressions_Processed (Flag108) 872-- A flag in subprograms (functions, operators, procedures) and in 873-- entries and entry families used to indicate that default expressions 874-- have been processed and to avoid multiple calls to process the 875-- default expressions (see Freeze.Process_Default_Expressions), which 876-- would not only waste time, but also generate false error messages. 877 878-- Default_Value (Node20) 879-- Defined in formal parameters. Points to the node representing the 880-- expression for the default value for the parameter. Empty if the 881-- parameter has no default value (which is always the case for OUT 882-- and IN OUT parameters in the absence of errors). 883 884-- Delay_Cleanups (Flag114) 885-- Defined in entities that have finalization lists (subprograms 886-- blocks, and tasks). Set if there are pending generic body 887-- instantiations for the corresponding entity. If this flag is 888-- set, then generation of cleanup actions for the corresponding 889-- entity must be delayed, since the insertion of the generic body 890-- may affect cleanup generation (see Inline for further details). 891 892-- Delay_Subprogram_Descriptors (Flag50) 893-- Defined in entities for which exception subprogram descriptors 894-- are generated (subprograms, package declarations and package 895-- bodies). Defined if there are pending generic body instantiations 896-- for the corresponding entity. If this flag is set, then generation 897-- of the subprogram descriptor for the corresponding enities must 898-- be delayed, since the insertion of the generic body may add entries 899-- to the list of handlers. 900-- 901-- Note: for subprograms, Delay_Subprogram_Descriptors is set if and 902-- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a 903-- a block (in which case Delay_Subprogram_Descriptors is set for the 904-- containing subprogram). In addition Delay_Subprogram_Descriptors is 905-- set for a library level package declaration or body which contains 906-- delayed instantiations (in this case the descriptor refers to the 907-- enclosing elaboration procedure). 908 909-- Delta_Value (Ureal18) 910-- Defined in fixed and decimal types. Points to a universal real 911-- that holds value of delta for the type, as given in the declaration 912-- or as inherited by a subtype or derived type. 913 914-- Dependent_Instances (Elist8) 915-- Defined in packages that are instances. Holds list of instances 916-- of inner generics. Used to place freeze nodes for those instances 917-- after that of the current one, i.e. after the corresponding generic 918-- bodies. 919 920-- Depends_On_Private (Flag14) 921-- Defined in all type entities. Set if the type is private or if it 922-- depends on a private type. 923 924-- Derived_Type_Link (Node31) 925-- Defined in all type and subtype entities. Set in a base type if 926-- a derived type declaration is encountered which derives from 927-- this base type or one of its subtypes, and there are already 928-- primitive operations declared. In this case, it references the 929-- entity for the type declared by the derived type declaration. 930-- For example: 931-- 932-- type R is ... 933-- subtype RS is R ... 934-- ... 935-- type G is new RS ... 936-- 937-- In this case, if primitive operations have been declared for R, at 938-- the point of declaration of G, then the Derived_Type_Link of R is set 939-- to point to the entity for G. This is used to generate warnings and 940-- errors for rep clauses that appear later on for R, which might result 941-- in an unexpected (or illegal) implicit conversion operation. 942-- 943-- Note: if there is more than one such derived type, the link will point 944-- to the last one. 945 946-- Designated_Type (synthesized) 947-- Applies to access types. Returns the designated type. Differs from 948-- Directly_Designated_Type in that if the access type refers to an 949-- incomplete type, and the full type is available, then this full type 950-- is returned instead of the incomplete type. 951 952-- DIC_Procedure (synthesized) 953-- Defined in all type entities. Set for a private type and its full view 954-- when the type is subject to pragma Default_Initial_Condition (DIC), or 955-- when the type inherits a DIC pragma from a parent type. Points to the 956-- entity of a procedure which takes a single argument of the given type 957-- and verifies the assertion expression of the DIC pragma at run time. 958 959-- Note: the reason this is marked as a synthesized attribute is that the 960-- way this is stored is as an element of the Subprograms_For_Type field. 961 962-- Digits_Value (Uint17) 963-- Defined in floating point types and subtypes and decimal types and 964-- subtypes. Contains the Digits value specified in the declaration. 965 966-- Direct_Primitive_Operations (Elist10) 967-- Defined in tagged types and subtypes (including synchronized types), 968-- in tagged private types and in tagged incomplete types. Element list 969-- of entities for primitive operations of the tagged type. Not defined 970-- in untagged types. In order to follow the C++ ABI, entities of 971-- primitives that come from source must be stored in this list in the 972-- order of their occurrence in the sources. For incomplete types the 973-- list is always empty. 974-- When expansion is disabled the corresponding record type of a 975-- synchronized type is not constructed. In that case, such types 976-- carry this attribute directly, for ASIS use. 977 978-- Directly_Designated_Type (Node20) 979-- Defined in access types. This field points to the type that is 980-- directly designated by the access type. In the case of an access 981-- type to an incomplete type, this field references the incomplete 982-- type. Directly_Designated_Type is typically used in implementing the 983-- static semantics of the language; in implementing dynamic semantics, 984-- we typically want the full view of the designated type. The function 985-- Designated_Type obtains this full type in the case of access to an 986-- incomplete type. 987 988-- Disable_Controlled (Flag253) 989-- Present in all entities. Set for a controlled type subject to aspect 990-- Disable_Controlled which evaluates to True. This flag is taken into 991-- account in synthesized attribute Is_Controlled. 992 993-- Discard_Names (Flag88) 994-- Defined in types and exception entities. Set if pragma Discard_Names 995-- applies to the entity. It is also set for declarative regions and 996-- package specs for which a Discard_Names pragma with zero arguments 997-- has been encountered. The purpose of setting this flag is to be able 998-- to set the Discard_Names attribute on enumeration types declared 999-- after the pragma within the same declarative region. This flag is 1000-- set to False if a Keep_Names pragma appears for an enumeration type. 1001 1002-- Discriminal (Node17) 1003-- Defined in discriminants (Discriminant formal: GNAT's first 1004-- coinage). The entity used as a formal parameter that corresponds 1005-- to a discriminant. See section "Handling of Discriminants" for 1006-- full details of the use of discriminals. 1007 1008-- Discriminal_Link (Node10) 1009-- Defined in E_In_Parameter or E_Constant entities. For discriminals, 1010-- points back to corresponding discriminant. For other entities, must 1011-- remain Empty. 1012 1013-- Discriminant_Checking_Func (Node20) 1014-- Defined in components. Points to the defining identifier of the 1015-- function built by the expander returns a Boolean indicating whether 1016-- the given record component exists for the current discriminant 1017-- values. 1018 1019-- Discriminant_Constraint (Elist21) 1020-- Defined in entities whose Has_Discriminants flag is set (concurrent 1021-- types, subtypes, record types and subtypes, private types and 1022-- subtypes, limited private types and subtypes and incomplete types). 1023-- It is an error to reference the Discriminant_Constraint field if 1024-- Has_Discriminants is False. 1025-- 1026-- If the Is_Constrained flag is set, Discriminant_Constraint points 1027-- to an element list containing the discriminant constraints in the 1028-- same order in which the discriminants are declared. 1029-- 1030-- If the Is_Constrained flag is not set but the discriminants of the 1031-- unconstrained type have default initial values then this field 1032-- points to an element list giving these default initial values in 1033-- the same order in which the discriminants are declared. Note that 1034-- in this case the entity cannot be a tagged record type, because 1035-- discriminants in this case cannot have defaults. 1036-- 1037-- If the entity is a tagged record implicit type, then this field is 1038-- inherited from the first subtype (so that the itype is subtype 1039-- conformant with its first subtype, which is needed when the first 1040-- subtype overrides primitive operations inherited by the implicit 1041-- base type). 1042-- 1043-- In all other cases Discriminant_Constraint contains the empty 1044-- Elist (i.e. it is initialized with a call to New_Elmt_List). 1045 1046-- Discriminant_Default_Value (Node20) 1047-- Defined in discriminants. Points to the node representing the 1048-- expression for the default value of the discriminant. Set to 1049-- Empty if the discriminant has no default value. 1050 1051-- Discriminant_Number (Uint15) 1052-- Defined in discriminants. Gives the ranking of a discriminant in 1053-- the list of discriminants of the type, i.e. a sequential integer 1054-- index starting at 1 and ranging up to number of discriminants. 1055 1056-- Dispatch_Table_Wrappers (Elist26) [implementation base type only] 1057-- Defined in E_Record_Type and E_Record_Subtype entities. Set in library 1058-- level tagged type entities if we are generating statically allocated 1059-- dispatch tables. Points to the list of dispatch table wrappers 1060-- associated with the tagged type. For an untagged record, contains 1061-- No_Elist. 1062 1063-- DTC_Entity (Node16) 1064-- Defined in function and procedure entities. Set to Empty unless 1065-- the subprogram is dispatching in which case it references the 1066-- Dispatch Table pointer Component. For regular Ada tagged this, this 1067-- is the _Tag component. For CPP_Class types and their descendants, 1068-- this points to the component entity in the record that holds the 1069-- Vtable pointer for the Vtable containing the entry referencing the 1070-- subprogram. 1071 1072-- DT_Entry_Count (Uint15) 1073-- Defined in E_Component entities. Only used for component marked 1074-- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table) 1075 1076-- DT_Offset_To_Top_Func (Node25) 1077-- Defined in E_Component entities. Only used for component marked 1078-- Is_Tag. If present it stores the Offset_To_Top function used to 1079-- provide this value in tagged types whose ancestor has discriminants. 1080 1081-- DT_Position (Uint15) 1082-- Defined in function and procedure entities which are dispatching 1083-- (should not be referenced without first checking that flag 1084-- Is_Dispatching_Operation is True). Contains the offset into 1085-- the Vtable for the entry that references the subprogram. 1086 1087-- Ekind (Ekind) 1088-- Defined in all entities. Contains a value of the enumeration type 1089-- Entity_Kind declared in a subsequent section in this spec. 1090 1091-- Elaborate_Body_Desirable (Flag210) 1092-- Defined in package entities. Set if the elaboration circuitry detects 1093-- a case where there is a package body that modifies one or more visible 1094-- entities in the package spec and there is no explicit Elaborate_Body 1095-- pragma for the package. This information is passed on to the binder, 1096-- which attempts, but does not promise, to elaborate the body as close 1097-- to the spec as possible. 1098 1099-- Elaboration_Entity (Node13) 1100-- Defined in entry, entry family, [generic] package, and subprogram 1101-- entities. This is a counter associated with the unit that is initially 1102-- set to zero, is incremented when an elaboration request for the unit 1103-- is made, and is decremented when a finalization request for the unit 1104-- is made. This is used for three purposes. First, it is used to 1105-- implement access before elaboration checks (the counter must be 1106-- non-zero to call a subprogram at elaboration time). Second, it is 1107-- used to guard against repeated execution of the elaboration code. 1108-- Third, it is used to ensure that the finalization code is executed 1109-- only after all clients have requested it. 1110-- 1111-- Note that we always allocate this counter, and set this field, but 1112-- we do not always actually use it. It is only used if it is needed 1113-- for access before elaboration use (see Elaboration_Entity_Required 1114-- flag) or if either the spec or the body has elaboration code. If 1115-- neither of these two conditions holds, then the entity is still 1116-- allocated (since we don't know early enough whether or not there 1117-- is elaboration code), but is simply not used for any purpose. 1118 1119-- Elaboration_Entity_Required (Flag174) 1120-- Defined in entry, entry family, [generic] package, and subprogram 1121-- entities. Set only if Elaboration_Entity is non-Empty to indicate that 1122-- the counter is required to be non-zero even if there is no other 1123-- elaboration code. This occurs when the Elaboration_Entity counter 1124-- is used for access before elaboration checks. If the counter is 1125-- only used to prevent multiple execution of the elaboration code, 1126-- then if there is no other elaboration code, obviously there is no 1127-- need to set the flag. 1128 1129-- Encapsulating_State (Node32) 1130-- Defined in abstract state, constant and variable entities. Contains 1131-- the entity of an ancestor state or a single concurrent type whose 1132-- refinement utilizes this item as a constituent. 1133 1134-- Enclosing_Scope (Node18) 1135-- Defined in labels. Denotes the innermost enclosing construct that 1136-- contains the label. Identical to the scope of the label, except for 1137-- labels declared in the body of an accept statement, in which case the 1138-- entry_name is the Enclosing_Scope. Used to validate goto's within 1139-- accept statements. 1140 1141-- Entry_Accepted (Flag152) 1142-- Defined in E_Entry and E_Entry_Family entities. Set if there is 1143-- at least one accept for this entry in the task body. Used to 1144-- generate warnings for missing accepts. 1145 1146-- Entry_Bodies_Array (Node19) 1147-- Defined in protected types for which Has_Entries is true. 1148-- This is the defining identifier for the array of entry body 1149-- action procedures and barrier functions used by the runtime to 1150-- execute the user code associated with each entry. 1151 1152-- Entry_Cancel_Parameter (Node23) 1153-- Defined in blocks. This only applies to a block statement for 1154-- which the Is_Asynchronous_Call_Block flag is set. It 1155-- contains the defining identifier of an object that must be 1156-- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call 1157-- call in the cleanup handler added to the block by 1158-- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean 1159-- object for task entry calls and a Communications_Block object 1160-- in the case of protected entry calls. In both cases the objects 1161-- are declared in outer scopes to this block. 1162 1163-- Entry_Component (Node11) 1164-- Defined in formal parameters (in, in out and out parameters). Used 1165-- only for formals of entries. References the corresponding component 1166-- of the entry parameter record for the entry. 1167 1168-- Entry_Formal (Node16) 1169-- Defined in components of the record built to correspond to entry 1170-- parameters. This field points from the component to the formal. It 1171-- is the back pointer corresponding to Entry_Component. 1172 1173-- Entry_Index_Constant (Node18) 1174-- Defined in an entry index parameter. This is an identifier that 1175-- eventually becomes the name of a constant representing the index 1176-- of the entry family member whose entry body is being executed. Used 1177-- to expand references to the entry index specification identifier. 1178 1179-- Entry_Index_Type (synthesized) 1180-- Applies to an entry family. Denotes Etype of the subtype indication 1181-- in the entry declaration. Used to resolve the index expression in an 1182-- accept statement for a member of the family, and in the prefix of 1183-- 'COUNT when it applies to a family member. 1184 1185-- Entry_Max_Queue_Lengths_Array (Node35) 1186-- Defined in protected types for which Has_Entries is true. Contains the 1187-- defining identifier for the array of naturals used by the runtime to 1188-- limit the queue size of each entry individually. 1189 1190-- Entry_Parameters_Type (Node15) 1191-- Defined in entries. Points to the access-to-record type that is 1192-- constructed by the expander to hold a reference to the parameter 1193-- values. This reference is manipulated (as an address) by the 1194-- tasking runtime. The designated record represents a packaging 1195-- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration 1196-- for further details). Entry_Parameters_Type is Empty if the entry 1197-- has no parameters. 1198 1199-- Enumeration_Pos (Uint11) 1200-- Defined in enumeration literals. Contains the position number 1201-- corresponding to the value of the enumeration literal. 1202 1203-- Enumeration_Rep (Uint12) 1204-- Defined in enumeration literals. Contains the representation that 1205-- corresponds to the value of the enumeration literal. Note that 1206-- this is normally the same as Enumeration_Pos except in the presence 1207-- of representation clauses, where Pos will still represent the 1208-- position of the literal within the type and Rep will have be the 1209-- value given in the representation clause. 1210 1211-- Enumeration_Rep_Expr (Node22) 1212-- Defined in enumeration literals. Points to the expression in an 1213-- associated enumeration rep clause that provides the representation 1214-- value for this literal. Empty if no enumeration rep clause for this 1215-- literal (or if rep clause does not have an entry for this literal, 1216-- an error situation). This is also used to catch duplicate entries 1217-- for the same literal. 1218 1219-- Enum_Pos_To_Rep (Node23) 1220-- Defined in enumeration types (but not enumeration subtypes). Set to 1221-- Empty unless the enumeration type has a non-standard representation 1222-- (i.e. at least one literal has a representation value different from 1223-- its pos value). In this case, Enum_Pos_To_Rep is the entity for an 1224-- array constructed when the type is frozen that maps Pos values to 1225-- corresponding Rep values. The index type of this array is Natural, 1226-- and the component type is a suitable integer type that holds the 1227-- full range of representation values. 1228 1229-- Equivalent_Type (Node18) 1230-- Defined in class wide types and subtypes, access to protected 1231-- subprogram types, and in exception types. For a classwide type, it 1232-- is always Empty. For a class wide subtype, it points to an entity 1233-- created by the expander which gives the backend an understandable 1234-- equivalent of the class subtype with a known size (given by an 1235-- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further 1236-- details. For E_Exception_Type, this points to the record containing 1237-- the data necessary to represent exceptions (for further details, see 1238-- System.Standard_Library). For access to protected subprograms, it 1239-- denotes a record that holds pointers to the operation and to the 1240-- protected object. For remote Access_To_Subprogram types, it denotes 1241-- the record that is the fat pointer representation of an RAST. 1242 1243-- Esize (Uint12) 1244-- Defined in all types and subtypes, and also for components, constants, 1245-- and variables, including exceptions where it refers to the static data 1246-- allocated for an exception. Contains the Object_Size of the type or of 1247-- the object. A value of zero indicates that the value is not yet known. 1248-- 1249-- For the case of components where a component clause is present, the 1250-- value is the value from the component clause, which must be non- 1251-- negative (but may be zero, which is acceptable for the case of 1252-- a type with only one possible value). It is also possible for Esize 1253-- of a component to be set without a component clause defined, which 1254-- means that the component size is specified, but not the position. 1255-- See also RM_Size and the section on "Handling of Type'Size Values". 1256-- During backend processing, the value is back annotated for all zero 1257-- values, so that after the call to the backend, the value is set. 1258 1259-- Etype (Node5) 1260-- Defined in all entities. Represents the type of the entity, which 1261-- is itself another entity. For a type entity, points to the parent 1262-- type for a derived type, or if the type is not derived, points to 1263-- itself. For a subtype entity, Etype points to the base type. For 1264-- a class wide type, points to the corresponding specific type. For a 1265-- subprogram or subprogram type, Etype has the return type of a function 1266-- or is set to Standard_Void_Type to represent a procedure. The Etype 1267-- field of a package is also set to Standard_Void_Type. 1268-- 1269-- Note one obscure case: for pragma Default_Storage_Pool (null), the 1270-- Etype of the N_Null node is Empty. 1271 1272-- Extra_Accessibility (Node13) 1273-- Defined in formal parameters in the non-generic case. Normally Empty, 1274-- but if expansion is active, and a parameter is one for which a 1275-- dynamic accessibility check is required, then an extra formal of type 1276-- Natural is created (see description of field Extra_Formal), and the 1277-- Extra_Accessibility field of the formal parameter points to the entity 1278-- for this extra formal. Also defined in variables when compiling 1279-- receiving stubs. In this case, a non Empty value means that this 1280-- variable's accessibility depth has been transmitted by the caller and 1281-- must be retrieved through the entity designed by this field instead of 1282-- being computed. 1283 1284-- Extra_Accessibility_Of_Result (Node19) 1285-- Defined in (non-generic) Function, Operator, and Subprogram_Type 1286-- entities. Normally Empty, but if expansion is active, and a function 1287-- is one for which "the accessibility level of the result ... determined 1288-- by the point of call" (AI05-0234) is needed, then an extra formal of 1289-- subtype Natural is created (see description of field Extra_Formal), 1290-- and the Extra_Accessibility_Of_Result field of the function points to 1291-- the entity for this extra formal. 1292 1293-- Extra_Constrained (Node23) 1294-- Defined in formal parameters in the non-generic case. Normally Empty, 1295-- but if expansion is active and a parameter is one for which a dynamic 1296-- indication of its constrained status is required, then an extra formal 1297-- of type Boolean is created (see description of field Extra_Formal), 1298-- and the Extra_Constrained field of the formal parameter points to the 1299-- entity for this extra formal. Also defined in variables when compiling 1300-- receiving stubs. In this case, a non empty value means that this 1301-- variable's constrained status has been transmitted by the caller and 1302-- must be retrieved through the entity designed by this field instead of 1303-- being computed. 1304 1305-- Extra_Formal (Node15) 1306-- Defined in formal parameters in the non-generic case. Certain 1307-- parameters require extra implicit information to be passed (e.g. the 1308-- flag indicating if an unconstrained variant record argument is 1309-- constrained, and the accessibility level for access parameters). See 1310-- description of Extra_Constrained, Extra_Accessibility fields for 1311-- further details. Extra formal parameters are constructed to represent 1312-- these values, and chained to the end of the list of formals using the 1313-- Extra_Formal field (i.e. the Extra_Formal field of the last "real" 1314-- formal points to the first extra formal, and the Extra_Formal field of 1315-- each extra formal points to the next one, with Empty indicating the 1316-- end of the list of extra formals). Another case of Extra_Formal arises 1317-- in connection with unnesting of subprograms, where the ARECnF formal 1318-- that represents an activation record pointer is an extra formal. 1319 1320-- Extra_Formals (Node28) 1321-- Applies to subprograms, subprogram types, entries, and entry 1322-- families. Returns first extra formal of the subprogram or entry. 1323-- Returns Empty if there are no extra formals. 1324 1325-- Finalization_Master (Node23) [root type only] 1326-- Defined in access-to-controlled or access-to-class-wide types. The 1327-- field contains the entity of the finalization master which handles 1328-- dynamically allocated controlled objects referenced by the access 1329-- type. Empty for access-to-subprogram types. Empty for access types 1330-- whose designated type does not need finalization actions. 1331 1332-- Finalize_Storage_Only (Flag158) [base type only] 1333-- Defined in all types. Set on direct controlled types to which a 1334-- valid Finalize_Storage_Only pragma applies. This flag is also set on 1335-- composite types when they have at least one controlled component and 1336-- all their controlled components are Finalize_Storage_Only. It is also 1337-- inherited by type derivation except for direct controlled types where 1338-- the Finalize_Storage_Only pragma is required at each level of 1339-- derivation. 1340 1341-- Finalizer (Node28) 1342-- Applies to package declarations and bodies. Contains the entity of the 1343-- library-level program which finalizes all package-level controlled 1344-- objects. 1345 1346-- First_Component (synthesized) 1347-- Applies to incomplete, private, protected, record and task types. 1348-- Returns the first component by following the chain of declared 1349-- entities for the type a component is found (one with an Ekind of 1350-- E_Component). The discriminants are skipped. If the record is null, 1351-- then Empty is returned. 1352 1353-- First_Component_Or_Discriminant (synthesized) 1354-- Similar to First_Component, but discriminants are not skipped, so will 1355-- find the first discriminant if discriminants are present. 1356 1357-- First_Entity (Node17) 1358-- Defined in all entities which act as scopes to which a list of 1359-- associated entities is attached (blocks, class subtypes and types, 1360-- entries, functions, loops, packages, procedures, protected objects, 1361-- record types and subtypes, private types, task types and subtypes). 1362-- Points to a list of associated entities using the Next_Entity field 1363-- as a chain pointer with Empty marking the end of the list. 1364 1365-- First_Exit_Statement (Node8) 1366-- Defined in E_Loop entity. The exit statements for a loop are chained 1367-- (in reverse order of appearance) using this field to point to the 1368-- first entry in the chain (last exit statement in the loop). The 1369-- entries are chained through the Next_Exit_Statement field of the 1370-- N_Exit_Statement node with Empty marking the end of the list. 1371 1372-- First_Formal (synthesized) 1373-- Applies to subprograms and subprogram types, and also to entries 1374-- and entry families. Returns first formal of the subprogram or entry. 1375-- The formals are the first entities declared in a subprogram or in 1376-- a subprogram type (the designated type of an Access_To_Subprogram 1377-- definition) or in an entry. 1378 1379-- First_Formal_With_Extras (synthesized) 1380-- Applies to subprograms and subprogram types, and also in entries 1381-- and entry families. Returns first formal of the subprogram or entry. 1382-- Returns Empty if there are no formals. The list returned includes 1383-- all the extra formals (see description of Extra_Formals field). 1384 1385-- First_Index (Node17) 1386-- Defined in array types and subtypes. By introducing implicit subtypes 1387-- for the index constraints, we have the same structure for constrained 1388-- and unconstrained arrays, subtype marks and discrete ranges are 1389-- both represented by a subtype. This function returns the tree node 1390-- corresponding to an occurrence of the first index (NOT the entity for 1391-- the type). Subsequent indices are obtained using Next_Index. Note that 1392-- this field is defined for the case of string literal subtypes, but is 1393-- always Empty. 1394 1395-- First_Literal (Node17) 1396-- Defined in all enumeration types, including character and boolean 1397-- types. This field points to the first enumeration literal entity 1398-- for the type (i.e. it is set to First (Literals (N)) where N is 1399-- the enumeration type definition node. A special case occurs with 1400-- standard character and wide character types, where this field is 1401-- Empty, since there are no enumeration literal lists in these cases. 1402-- Note that this field is set in enumeration subtypes, but it still 1403-- points to the first literal of the base type in this case. 1404 1405-- First_Private_Entity (Node16) 1406-- Defined in all entities containing private parts (packages, protected 1407-- types and subtypes, task types and subtypes). The entities on the 1408-- entity chain are in order of declaration, so the entries for private 1409-- entities are at the end of the chain. This field points to the first 1410-- entity for the private part. It is Empty if there are no entities 1411-- declared in the private part or if there is no private part. 1412 1413-- First_Rep_Item (Node6) 1414-- Defined in all entities. If non-empty, points to a linked list of 1415-- representation pragmas nodes and representation clause nodes that 1416-- apply to the entity, linked using Next_Rep_Item, with Empty marking 1417-- the end of the list. In the case of derived types and subtypes, the 1418-- new entity inherits the chain at the point of declaration. This means 1419-- that it is possible to have multiple instances of the same kind of rep 1420-- item on the chain, in which case it is the first one that applies to 1421-- the entity. 1422-- 1423-- Note: pragmas that can apply to more than one overloadable entity, 1424-- (Convention, Interface, Inline, Inline_Always, Import, Export, 1425-- External) are never present on this chain when they apply to 1426-- overloadable entities, since it is impossible for a given pragma 1427-- to be on more than one chain at a time. 1428-- 1429-- For most representation items, the representation information is 1430-- reflected in other fields and flags in the entity. For example if a 1431-- record representation clause is present, the component entities 1432-- reflect the specified information. However, there are some items that 1433-- are only reflected in the chain. These include: 1434-- 1435-- Machine_Attribute pragma 1436-- Link_Alias pragma 1437-- Linker_Constructor pragma 1438-- Linker_Destructor pragma 1439-- Weak_External pragma 1440-- Thread_Local_Storage pragma 1441-- 1442-- If any of these items are present, then the flag Has_Gigi_Rep_Item is 1443-- set, indicating that the backend should search the chain. 1444-- 1445-- Other representation items are included in the chain so that error 1446-- messages can easily locate the relevant nodes for posting errors. 1447-- Note in particular that size clauses are defined only for this 1448-- purpose, and should only be accessed if Has_Size_Clause is set. 1449 1450-- Float_Rep (Uint10) 1451-- Defined in floating-point entities. Contains a value of type 1452-- Float_Rep_Kind. Together with the Digits_Value uniquely defines 1453-- the floating-point representation to be used. 1454 1455-- Freeze_Node (Node7) 1456-- Defined in all entities. If there is an associated freeze node for the 1457-- entity, this field references this freeze node. If no freeze node is 1458-- associated with the entity, then this field is Empty. See package 1459-- Freeze for further details. 1460 1461-- From_Limited_With (Flag159) 1462-- Defined in abtract states, package and type entities. Set to True when 1463-- the related entity is generated by the expansion of a limited with 1464-- clause. Such an entity is said to be a "shadow" - it acts as the 1465-- abstract view of a state or variable or as the incomplete view of a 1466-- type by inheriting relevant attributes from the said entity. 1467 1468-- Full_View (Node11) 1469-- Defined in all type and subtype entities and in deferred constants. 1470-- References the entity for the corresponding full type or constant 1471-- declaration. For all types other than private and incomplete types, 1472-- this field always contains Empty. If an incomplete type E1 is 1473-- completed by a private type E2 whose full type declaration entity is 1474-- E3 then the full view of E1 is E2, and the full view of E2 is E3. See 1475-- also Underlying_Type. 1476 1477-- Generic_Homonym (Node11) 1478-- Defined in generic packages. The generic homonym is the entity of 1479-- a renaming declaration inserted in every generic unit. It is used 1480-- to resolve the name of a local entity that is given by a qualified 1481-- name, when the generic entity itself is hidden by a local name. 1482 1483-- Generic_Renamings (Elist23) 1484-- Defined in package and subprogram instances. Holds mapping that 1485-- associates generic parameters with the corresponding instances, in 1486-- those cases where the instance is an entity. 1487 1488-- Handler_Records (List10) 1489-- Defined in subprogram and package entities. Points to a list of 1490-- identifiers referencing the handler record entities for the 1491-- corresponding unit. 1492 1493-- Has_Aliased_Components (Flag135) [implementation base type only] 1494-- Defined in array type entities. Indicates that the component type 1495-- of the array is aliased. Should this also be set for records to 1496-- indicate that at least one component is aliased (see processing in 1497-- Sem_Prag.Process_Atomic_Independent_Shared_Volatile???) 1498 1499-- Has_Alignment_Clause (Flag46) 1500-- Defined in all type entities and objects. Indicates if an alignment 1501-- clause has been given for the entity. If set, then Alignment_Clause 1502-- returns the N_Attribute_Definition node for the alignment attribute 1503-- definition clause. Note that it is possible for this flag to be False 1504-- even when Alignment_Clause returns non_Empty (this happens in the case 1505-- of derived type declarations). 1506 1507-- Has_All_Calls_Remote (Flag79) 1508-- Defined in all library unit entities. Set if the library unit has an 1509-- All_Calls_Remote pragma. Note that such entities must also be RCI 1510-- entities, so the flag Is_Remote_Call_Interface will always be set if 1511-- this flag is set. 1512 1513-- Has_Atomic_Components (Flag86) [implementation base type only] 1514-- Defined in all types and objects. Set only for an array type or 1515-- an array object if a valid pragma Atomic_Components applies to the 1516-- type or object. Note that in the case of an object, this flag is 1517-- only set on the object if there was an explicit pragma for the 1518-- object. In other words, the proper test for whether an object has 1519-- atomic components is to see if either the object or its base type 1520-- has this flag set. Note that in the case of a type, the pragma will 1521-- be chained to the rep item chain of the first subtype in the usual 1522-- manner. 1523 1524-- Has_Attach_Handler (synthesized) 1525-- Applies to record types that are constructed by the expander to 1526-- represent protected types. Returns True if there is at least one 1527-- Attach_Handler pragma in the corresponding specification. 1528 1529-- Has_Biased_Representation (Flag139) 1530-- Defined in discrete types (where it applies to the type'size value), 1531-- and to objects (both stand-alone and components), where it applies to 1532-- the size of the object from a size or record component clause. In 1533-- all cases it indicates that the size in question is smaller than 1534-- would normally be required, but that the size requirement can be 1535-- satisfied by using a biased representation, in which stored values 1536-- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to 1537-- reduce the required size. For example, a type with a range of 1..2 1538-- takes one bit, using 0 to represent 1 and 1 to represent 2. 1539-- 1540-- Note that in the object and component cases, the flag is only set if 1541-- the type is unbiased, but the object specifies a smaller size than the 1542-- size of the type, forcing biased representation for the object, but 1543-- the subtype is still an unbiased type. 1544 1545-- Has_Completion (Flag26) 1546-- Defined in all entities that require a completion (functions, 1547-- procedures, private types, limited private types, incomplete types, 1548-- constants and packages that require a body). The flag is set if the 1549-- completion has been encountered and analyzed. 1550 1551-- Has_Completion_In_Body (Flag71) 1552-- Defined in all entities for types and subtypes. Set only in "Taft 1553-- amendment types" (incomplete types whose full declaration appears in 1554-- the package body). 1555 1556-- Has_Complex_Representation (Flag140) [implementation base type only] 1557-- Defined in record types. Set only for a base type to which a valid 1558-- pragma Complex_Representation applies. 1559 1560-- Has_Component_Size_Clause (Flag68) [implementation base type only] 1561-- Defined in all type entities. Set if a component size clause is 1562-- Defined for the given type. Note that this flag can be False even 1563-- if Component_Size is non-zero (happens in the case of derived types). 1564 1565-- Has_Constrained_Partial_View (Flag187) 1566-- Defined in private type and their completions, when the private 1567-- type has no discriminants and the full view has discriminants with 1568-- defaults. In Ada 2005 heap-allocated objects of such types are not 1569-- constrained, and can change their discriminants with full assignment. 1570-- 1571-- Ada 2012 has an additional rule (3.3. (23/10.3)) concerning objects 1572-- declared in a generic package body. Objects whose type is an untagged 1573-- generic formal private type are considered to have a constrained 1574-- partial view. The predicate Object_Type_Has_Constrained_Partial_View 1575-- in sem_aux is used to test for this case. 1576 1577-- Has_Contiguous_Rep (Flag181) 1578-- Defined in enumeration types. Set if the type as a representation 1579-- clause whose entries are successive integers. 1580 1581-- Has_Controlled_Component (Flag43) [base type only] 1582-- Defined in all type and subtype entities. Set only for composite type 1583-- entities which contain a component that either is a controlled type, 1584-- or itself contains controlled component (i.e. either Is_Controlled or 1585-- Has_Controlled_Component is set for at least one component). 1586 1587-- Has_Controlling_Result (Flag98) 1588-- Defined in E_Function entities. Set if the function is a primitive 1589-- function of a tagged type which can dispatch on result. 1590 1591-- Has_Convention_Pragma (Flag119) 1592-- Defined in all entities. Set for an entity for which a valid pragma 1593-- Convention, Import, or Export has been given. Used to prevent more 1594-- than one such pragma appearing for a given entity (RM B.1(45)). 1595 1596-- Has_Default_Aspect (Flag39) [base type only] 1597-- Defined in entities for types and subtypes, set for scalar types with 1598-- a Default_Value aspect and array types with a Default_Component_Value 1599-- aspect. If this flag is set, then a corresponding aspect specification 1600-- node will be present on the rep item chain for the entity. For a 1601-- derived type that inherits a default from its ancestor, the default 1602-- value is set, but it may be overridden by an aspect declaration on 1603-- type derivation. 1604 1605-- Has_Delayed_Aspects (Flag200) 1606-- Defined in all entities. Set if the Rep_Item chain for the entity has 1607-- one or more N_Aspect_Definition nodes chained which are not to be 1608-- evaluated till the freeze point. The aspect definition expression 1609-- clause has been preanalyzed to get visibility at the point of use, 1610-- but no other action has been taken. 1611 1612-- Has_Delayed_Freeze (Flag18) 1613-- Defined in all entities. Set to indicate that an explicit freeze 1614-- node must be generated for the entity at its freezing point. See 1615-- separate section ("Delayed Freezing and Elaboration") for details. 1616 1617-- Has_Delayed_Rep_Aspects (Flag261) 1618-- Defined in all types and subtypes. This flag is set if there is at 1619-- least one aspect for a representation characteristic that has to be 1620-- delayed and is one of the characteristics that may be inherited by 1621-- types derived from this type if not overridden. If this flag is set, 1622-- then types derived from this type have May_Inherit_Delayed_Rep_Aspects 1623-- set, signalling that Freeze.Inherit_Delayed_Rep_Aspects must be called 1624-- at the freeze point of the derived type. 1625 1626-- Has_DIC (synthesized) 1627-- Defined in all type entities. Set for a private type and its full view 1628-- when the type is subject to pragma Default_Initial_Condition (DIC), or 1629-- when the type inherits a DIC pragma from a parent type. 1630 1631-- Has_Discriminants (Flag5) 1632-- Defined in all types and subtypes. For types that are allowed to have 1633-- discriminants (record types and subtypes, task types and subtypes, 1634-- protected types and subtypes, private types, limited private types, 1635-- and incomplete types), indicates if the corresponding type or subtype 1636-- has a known discriminant part. Always false for all other types. 1637 1638-- Has_Dispatch_Table (Flag220) 1639-- Defined in E_Record_Types that are tagged. Set to indicate that the 1640-- corresponding dispatch table is already built. This flag is used to 1641-- avoid duplicate construction of library level dispatch tables (because 1642-- the declaration of library level objects cause premature construction 1643-- of the table); otherwise the code that builds the table is added at 1644-- the end of the list of declarations of the package. 1645 1646-- Has_Dynamic_Predicate_Aspect (Flag258) 1647-- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect 1648-- was explicitly applied to the type. Generally we treat predicates as 1649-- static if possible, regardless of whether they are specified using 1650-- Predicate, Static_Predicate, or Dynamic_Predicate. And if a predicate 1651-- can be treated as static (i.e. its expression is predicate-static), 1652-- then the flag Has_Static_Predicate will be set True. But there are 1653-- cases where legality is affected by the presence of an explicit 1654-- Dynamic_Predicate aspect. For example, even if a predicate looks 1655-- static, you can't use it in a case statement if there is an explicit 1656-- Dynamic_Predicate aspect specified. So test Has_Static_Predicate if 1657-- you just want to know if the predicate can be evaluated statically, 1658-- but test Has_Dynamic_Predicate_Aspect to enforce legality rules about 1659-- the use of dynamic predicates. 1660 1661-- Has_Entries (synthesized) 1662-- Applies to concurrent types. True if any entries are declared 1663-- within the task or protected definition for the type. 1664 1665-- Has_Enumeration_Rep_Clause (Flag66) 1666-- Defined in enumeration types. Set if an enumeration representation 1667-- clause has been given for this enumeration type. Used to prevent more 1668-- than one enumeration representation clause for a given type. Note 1669-- that this does not imply a representation with holes, since the rep 1670-- clause may merely confirm the default 0..N representation. 1671 1672-- Has_Exit (Flag47) 1673-- Defined in loop entities. Set if the loop contains an exit statement. 1674 1675-- Has_Expanded_Contract (Flag240) 1676-- Defined in functions, procedures, entries, and entry families. Set 1677-- when a subprogram has a N_Contract node that has been expanded. The 1678-- flag prevents double expansion of a contract when a construct is 1679-- rewritten into something else and subsequently reanalyzed/expanded. 1680 1681-- Has_Foreign_Convention (synthesized) 1682-- Applies to all entities. Determines if the Convention for the 1683-- entity is a foreign convention (i.e. is other than Convention_Ada, 1684-- Convention_Intrinsic, Convention_Entry or Convention_Protected). 1685 1686-- Has_Forward_Instantiation (Flag175) 1687-- Defined in package entities. Set for packages that instantiate local 1688-- generic entities before the corresponding generic body has been seen. 1689-- If a package has a forward instantiation, we cannot inline subprograms 1690-- appearing in the same package because the placement requirements of 1691-- the instance will conflict with the linear elaboration of front-end 1692-- inlining. 1693 1694-- Has_Fully_Qualified_Name (Flag173) 1695-- Defined in all entities. Set if the name in the Chars field has been 1696-- replaced by the fully qualified name, as used for debug output. See 1697-- Exp_Dbug for a full description of the use of this flag and also the 1698-- related flag Has_Qualified_Name. 1699 1700-- Has_Gigi_Rep_Item (Flag82) 1701-- Defined in all entities. Set if the rep item chain (referenced by 1702-- First_Rep_Item and linked through the Next_Rep_Item chain) contains a 1703-- representation item that needs to be specially processed by the back 1704-- end, i.e. one of the following items: 1705-- 1706-- Machine_Attribute pragma 1707-- Linker_Alias pragma 1708-- Linker_Constructor pragma 1709-- Linker_Destructor pragma 1710-- Weak_External pragma 1711-- Thread_Local_Storage pragma 1712-- 1713-- If this flag is set, then the backend should scan the rep item chain 1714-- to process any of these items that appear. At least one such item will 1715-- be present. 1716-- 1717-- Has_Homonym (Flag56) 1718-- Defined in all entities. Set if an entity has a homonym in the same 1719-- scope. Used by the backend to generate unique names for all entities. 1720 1721-- Has_Implicit_Dereference (Flag251) 1722-- Defined in types and discriminants. Set if the type has an aspect 1723-- Implicit_Dereference. Set also on the discriminant named in the aspect 1724-- clause, to simplify type resolution. 1725 1726-- Has_Independent_Components (Flag34) [implementation base type only] 1727-- Defined in all types and objects. Set only for a record type or an 1728-- array type or array object if a valid pragma Independent_Components 1729-- applies to the type or object. Note that in the case of an object, 1730-- this flag is only set on the object if there was an explicit pragma 1731-- for the object. In other words, the proper test for whether an object 1732-- has independent components is to see if either the object or its base 1733-- type has this flag set. Note that in the case of a type, the pragma 1734-- will be chained to the rep item chain of the first subtype in the 1735-- usual manner. Also set if a pragma Has_Atomic_Components or pragma 1736-- Has_Aliased_Components applies to the type or object. 1737 1738-- Has_Inheritable_Invariants (Flag248) [base type only] 1739-- Defined in all type entities. Set on private types and interface types 1740-- which define at least one class-wide invariant. Such invariants must 1741-- be inherited by derived types. The flag is also set on the full view 1742-- of a private type for completeness. 1743 1744-- Has_Inherited_DIC (Flag133) [base type only] 1745-- Defined in all type entities. Set for a derived type which inherits 1746-- pragma Default_Initial_Condition from a parent type. 1747 1748-- Has_Inherited_Invariants (Flag291) [base type only] 1749-- Defined in all type entities. Set on private extensions and derived 1750-- types which inherit at least one class-wide invariant from a parent or 1751-- an interface type. The flag is also set on the full view of a private 1752-- extension for completeness. 1753 1754-- Has_Initial_Value (Flag219) 1755-- Defined in entities for variables and out parameters. Set if there 1756-- is an explicit initial value expression in the declaration of the 1757-- variable. Note that this is set only if this initial value is 1758-- explicit, it is not set for the case of implicit initialization 1759-- of access types or controlled types. Always set to False for out 1760-- parameters. Also defined in entities for in and in-out parameters, 1761-- but always false in these cases. 1762 1763-- Has_Interrupt_Handler (synthesized) 1764-- Applies to all protected type entities. Set if the protected type 1765-- definition contains at least one procedure to which a pragma 1766-- Interrupt_Handler applies. 1767 1768-- Has_Invariants (synthesized) 1769-- Defined in all type entities. True if the type defines at least one 1770-- invariant of its own or inherits at least one class-wide invariant 1771-- from a parent type or an interface. 1772 1773-- Has_Loop_Entry_Attributes (Flag260) 1774-- Defined in E_Loop entities. Set when the loop is subject to at least 1775-- one attribute 'Loop_Entry. The flag also implies that the loop has 1776-- already been transformed. See Expand_Loop_Entry_Attribute for details. 1777 1778-- Has_Machine_Radix_Clause (Flag83) 1779-- Defined in decimal types and subtypes, set if a Machine_Radix 1780-- representation clause is present. This flag is used to detect 1781-- the error of multiple machine radix clauses for a single type. 1782 1783-- Has_Master_Entity (Flag21) 1784-- Defined in entities that can appear in the scope stack (see spec 1785-- of Sem). It is set if a task master entity (_master) has been 1786-- declared and initialized in the corresponding scope. 1787 1788-- Has_Missing_Return (Flag142) 1789-- Defined in functions and generic functions. Set if there is one or 1790-- more missing return statements in the function. This is used to 1791-- control wrapping of the body in Exp_Ch6 to ensure that the program 1792-- error exception is correctly raised in this case at run time. 1793 1794-- Has_Nested_Block_With_Handler (Flag101) 1795-- Defined in scope entities. Set if there is a nested block within the 1796-- scope that has an exception handler and the two scopes are in the 1797-- same procedure. This is used by the backend for controlling certain 1798-- optimizations to ensure that they are consistent with exceptions. 1799-- See documentation in backend for further details. 1800 1801-- Has_Nested_Subprogram (Flag282) 1802-- Defined in subprogram entities. Set for a subprogram which contains at 1803-- least one nested subprogram. 1804 1805-- Has_Non_Limited_View (synth) 1806-- Defined in E_Incomplete_Type, E_Incomplete_Subtype, E_Class_Wide_Type, 1807-- E_Abstract_State entities. True if their Non_Limited_View attribute 1808-- is present. 1809 1810-- Has_Non_Null_Abstract_State (synth) 1811-- Defined in package entities. True if the package is subject to a non- 1812-- null Abstract_State aspect/pragma. 1813 1814-- Has_Non_Null_Visible_Refinement (synth) 1815-- Defined in E_Abstract_State entities. True if the state has a visible 1816-- refinement of at least one variable or state constituent as expressed 1817-- in aspect/pragma Refined_State. 1818 1819-- Has_Non_Standard_Rep (Flag75) [implementation base type only] 1820-- Defined in all type entities. Set when some representation clause 1821-- or pragma causes the representation of the item to be significantly 1822-- modified. In this category are changes of small or radix for a 1823-- fixed-point type, change of component size for an array, and record 1824-- or enumeration representation clauses, as well as packed pragmas. 1825-- All other representation clauses (e.g. Size and Alignment clauses) 1826-- are not considered to be significant since they do not affect 1827-- stored bit patterns. 1828 1829-- Has_Null_Abstract_State (synth) 1830-- Defined in package entities. True if the package is subject to a null 1831-- Abstract_State aspect/pragma. 1832 1833-- Has_Null_Visible_Refinement (synth) 1834-- Defined in E_Abstract_State entities. True if the state has a visible 1835-- null refinement as expressed in aspect/pragma Refined_State. 1836 1837-- Has_Object_Size_Clause (Flag172) 1838-- Defined in entities for types and subtypes. Set if an Object_Size 1839-- clause has been processed for the type. Used to prevent multiple 1840-- Object_Size clauses for a given entity. 1841 1842-- Has_Out_Or_In_Out_Parameter (Flag110) 1843-- Present in subprograms, generic subprograms, entries, and entry 1844-- families. Set if they have at least one OUT or IN OUT parameter 1845-- (allowed for functions only in Ada 2012). 1846 1847-- Has_Own_DIC (Flag3) [base type only] 1848-- Defined in all type entities. Set for a private type and its full view 1849-- when the type is subject to pragma Default_Initial_Condition. 1850 1851-- Has_Own_Invariants (Flag232) [base type only] 1852-- Defined in all type entities. Set on any type that defines at least 1853-- one invariant of its own. The flag is also set on the full view of a 1854-- private type for completeness. 1855 1856-- Has_Partial_Visible_Refinement (Flag296) 1857-- Defined in E_Abstract_State entities. Set when a state has at least 1858-- one refinement constituent subject to indicator Part_Of, and analysis 1859-- is in the region between the declaration of the first constituent for 1860-- this abstract state (in the private part of the package) and the end 1861-- of the package spec or body with visibility over this private part 1862-- (which includes the package itself and its child packages). 1863 1864-- Has_Per_Object_Constraint (Flag154) 1865-- Defined in E_Component entities. Set if the subtype of the component 1866-- has a per object constraint. Per object constraints result from the 1867-- following situations : 1868-- 1869-- 1. N_Attribute_Reference - when the prefix is the enclosing type and 1870-- the attribute is Access. 1871-- 2. N_Discriminant_Association - when the expression uses the 1872-- discriminant of the enclosing type. 1873-- 3. N_Index_Or_Discriminant_Constraint - when at least one of the 1874-- individual constraints is a per object constraint. 1875-- 4. N_Range - when the lower or upper bound uses the discriminant of 1876-- the enclosing type. 1877-- 5. N_Range_Constraint - when the range expression uses the 1878-- discriminant of the enclosing type. 1879 1880-- Has_Pragma_Controlled (Flag27) [implementation base type only] 1881-- Defined in access type entities. It is set if a pragma Controlled 1882-- applies to the access type. 1883 1884-- Has_Pragma_Elaborate_Body (Flag150) 1885-- Defined in all entities. Set in compilation unit entities if a 1886-- pragma Elaborate_Body applies to the compilation unit. 1887 1888-- Has_Pragma_Inline (Flag157) 1889-- Defined in all entities. Set for functions and procedures for which a 1890-- pragma Inline or Inline_Always applies to the subprogram. Note that 1891-- this flag can be set even if Is_Inlined is not set. This happens for 1892-- pragma Inline (if Inline_Active is False). In other words, the flag 1893-- Has_Pragma_Inline represents the formal semantic status, and is used 1894-- for checking semantic correctness. The flag Is_Inlined indicates 1895-- whether inlining is actually active for the entity. 1896 1897-- Has_Pragma_Inline_Always (Flag230) 1898-- Defined in all entities. Set for functions and procedures for which a 1899-- pragma Inline_Always applies. Note that if this flag is set, the flag 1900-- Has_Pragma_Inline is also set. 1901 1902-- Has_Pragma_No_Inline (Flag201) 1903-- Defined in all entities. Set for functions and procedures for which a 1904-- pragma No_Inline applies. Note that if this flag is set, the flag 1905-- Has_Pragma_Inline_Always cannot be set. 1906 1907-- Has_Pragma_Ordered (Flag198) [implementation base type only] 1908-- Defined in entities for enumeration types. If set indicates that a 1909-- valid pragma Ordered was given for the type. This flag is inherited 1910-- by derived enumeration types. We don't need to distinguish the derived 1911-- case since we allow multiple occurrences of this pragma anyway. 1912 1913-- Has_Pragma_Pack (Flag121) [implementation base type only] 1914-- Defined in array and record type entities. If set, indicates that a 1915-- valid pragma Pack was given for the type. Note that this flag is not 1916-- inherited by derived type. See also the Is_Packed flag. 1917 1918-- Has_Pragma_Preelab_Init (Flag221) 1919-- Defined in type and subtype entities. If set indicates that a valid 1920-- pragma Preelaborable_Initialization applies to the type. 1921 1922-- Has_Pragma_Pure (Flag203) 1923-- Defined in all entities. If set, indicates that a valid pragma Pure 1924-- was given for the entity. In some cases, we need to test whether 1925-- Is_Pure was explicitly set using this pragma. 1926 1927-- Has_Pragma_Pure_Function (Flag179) 1928-- Defined in all entities. If set, indicates that a valid pragma 1929-- Pure_Function was given for the entity. In some cases, we need to test 1930-- whether Is_Pure was explicitly set using this pragma. We also set 1931-- this flag for some internal entities that we know should be treated 1932-- as pure for optimization purposes. 1933 1934-- Has_Pragma_Thread_Local_Storage (Flag169) 1935-- Defined in all entities. If set, indicates that a valid pragma 1936-- Thread_Local_Storage was given for the entity. 1937 1938-- Has_Pragma_Unmodified (Flag233) 1939-- Defined in all entities. Can only be set for variables (E_Variable, 1940-- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified 1941-- applies to the variable, indicating that no warning should be given 1942-- if the entity is never modified. Note that clients should generally 1943-- not test this flag directly, but instead use function Has_Unmodified. 1944 1945-- Has_Pragma_Unreferenced (Flag180) 1946-- Defined in all entities. Set if a valid pragma Unreferenced applies 1947-- to the entity, indicating that no warning should be given if the 1948-- entity has no references, but a warning should be given if it is 1949-- in fact referenced. For private types, this flag is set in both the 1950-- private entity and full entity if the pragma applies to either. Note 1951-- that clients should generally not test this flag directly, but instead 1952-- use function Has_Unreferenced. 1953 1954-- ??? this real description was clobbered 1955 1956-- Has_Pragma_Unreferenced_Objects (Flag212) 1957-- Defined in all entities. Set if a valid pragma Unused applies to an 1958-- entity, indicating that warnings should be given if the entity is 1959-- modified or referenced. This pragma is equivalent to a pair of 1960-- Unmodified and Unreferenced pragmas. 1961 1962-- Has_Pragma_Unused (Flag294) 1963-- Defined in all entities. Set if a valid pragma Unused applies to a 1964-- variable or entity, indicating that warnings should not be given if 1965-- it is never modified or referenced. Note: This pragma is exactly 1966-- equivalent Unmodified and Unreference combined. 1967 1968-- Has_Predicates (Flag250) 1969-- Defined in type and subtype entities. Set if a pragma Predicate or 1970-- Predicate aspect applies to the type or subtype, or if it inherits a 1971-- Predicate aspect from its parent or progenitor types. 1972-- 1973-- Note: this flag is set on both partial and full view of types to which 1974-- a Predicate pragma or aspect applies. 1975 1976-- Has_Primitive_Operations (Flag120) [base type only] 1977-- Defined in all type entities. Set if at least one primitive operation 1978-- is defined for the type. 1979 1980-- Has_Private_Ancestor (Flag151) 1981-- Applies to type extensions. True if some ancestor is derived from a 1982-- private type, making some components invisible and aggregates illegal. 1983-- This flag is set at the point of derivation. The legality of the 1984-- aggregate must be rechecked because it also depends on the visibility 1985-- at the point the aggregate is resolved. See sem_aggr.adb. This is part 1986-- of AI05-0115. 1987 1988-- Has_Private_Declaration (Flag155) 1989-- Defined in all entities. Set if it is the defining entity of a private 1990-- type declaration or its corresponding full declaration. This flag is 1991-- thus preserved when the full and the partial views are exchanged, to 1992-- indicate if a full type declaration is a completion. Used for semantic 1993-- checks in E.4(18) and elsewhere. 1994 1995-- Has_Private_Extension (Flag300) 1996-- Defined in tagged types. Set to indicate that the tagged type has some 1997-- private extension. Used to report a warning on public primitives added 1998-- after defining its private extensions. 1999 2000-- Has_Protected (Flag271) [base type only] 2001-- Defined in all type entities. Set on protected types themselves, and 2002-- also (recursively) on any composite type which has a component for 2003-- which Has_Protected is set, unless the protected type is declared in 2004-- the private part of an internal unit. The meaning is that restrictions 2005-- for protected types apply to this type. Note: the flag is not set on 2006-- access types, even if they designate an object that Has_Protected. 2007 2008-- Has_Qualified_Name (Flag161) 2009-- Defined in all entities. Set if the name in the Chars field has 2010-- been replaced by its qualified name, as used for debug output. See 2011-- Exp_Dbug for a full description of qualification requirements. For 2012-- some entities, the name is the fully qualified name, but there are 2013-- exceptions. In particular, for local variables in procedures, we 2014-- do not include the procedure itself or higher scopes. See also the 2015-- flag Has_Fully_Qualified_Name, which is set if the name does indeed 2016-- include the fully qualified name. 2017 2018-- Has_RACW (Flag214) 2019-- Defined in package spec entities. Set if the spec contains the 2020-- declaration of a remote access-to-classwide type. 2021 2022-- Has_Record_Rep_Clause (Flag65) [implementation base type only] 2023-- Defined in record types. Set if a record representation clause has 2024-- been given for this record type. Used to prevent more than one such 2025-- clause for a given record type. Note that this is initially cleared 2026-- for a derived type, even though the representation is inherited. See 2027-- also the flag Has_Specified_Layout. 2028 2029-- Has_Recursive_Call (Flag143) 2030-- Defined in procedures. Set if a direct parameterless recursive call 2031-- is detected while analyzing the body. Used to activate some error 2032-- checks for infinite recursion. 2033 2034-- Has_Shift_Operator (Flag267) [base type only] 2035-- Defined in integer types. Set in the base type of an integer type for 2036-- which at least one of the shift operators is defined. 2037 2038-- Has_Size_Clause (Flag29) 2039-- Defined in entities for types and objects. Set if a size clause is 2040-- defined for the entity. Used to prevent multiple Size clauses for a 2041-- given entity. Note that it is always initially cleared for a derived 2042-- type, even though the Size for such a type is inherited from a Size 2043-- clause given for the parent type. 2044 2045-- Has_Small_Clause (Flag67) 2046-- Defined in ordinary fixed point types (but not subtypes). Indicates 2047-- that a small clause has been given for the entity. Used to prevent 2048-- multiple Small clauses for a given entity. Note that it is always 2049-- initially cleared for a derived type, even though the Small for such 2050-- a type is inherited from a Small clause given for the parent type. 2051 2052-- Has_Specified_Layout (Flag100) [implementation base type only] 2053-- Defined in all type entities. Set for a record type or subtype if 2054-- the record layout has been specified by a record representation 2055-- clause. Note that this differs from the flag Has_Record_Rep_Clause 2056-- in that it is inherited by a derived type. Has_Record_Rep_Clause is 2057-- used to indicate that the type is mentioned explicitly in a record 2058-- representation clause, and thus is not inherited by a derived type. 2059-- This flag is always False for non-record types. 2060 2061-- Has_Specified_Stream_Input (Flag190) 2062-- Has_Specified_Stream_Output (Flag191) 2063-- Has_Specified_Stream_Read (Flag192) 2064-- Has_Specified_Stream_Write (Flag193) 2065-- Defined in all type and subtype entities. Set for a given view if the 2066-- corresponding stream-oriented attribute has been defined by an 2067-- attribute definition clause. When such a clause occurs, a TSS is set 2068-- on the underlying full view; the flags are used to track visibility of 2069-- the attribute definition clause for partial or incomplete views. 2070 2071-- Has_Static_Discriminants (Flag211) 2072-- Defined in record subtypes constrained by discriminant values. Set if 2073-- all the discriminant values have static values, meaning that in the 2074-- case of a variant record, the component list can be trimmed down to 2075-- include only the components corresponding to these discriminants. 2076 2077-- Has_Static_Predicate (Flag269) 2078-- Defined in all types and subtypes. Set if the type (which must be a 2079-- scalar type) has a predicate whose expression is predicate-static. 2080-- This can result from the use of any Predicate, Static_Predicate, or 2081-- Dynamic_Predicate aspect. We can distinguish these cases by testing 2082-- Has_Static_Predicate_Aspect and Has_Dynamic_Predicate_Aspect. See 2083-- description of the latter flag for further information on dynamic 2084-- predicates which are also static. 2085 2086-- Has_Static_Predicate_Aspect (Flag259) 2087-- Defined in all types and subtypes. Set if a Static_Predicate aspect 2088-- applies to the type. Note that we can tell if a static predicate is 2089-- present by looking at Has_Static_Predicate, but this could have come 2090-- from a Predicate aspect or pragma or even from a Dynamic_Predicate 2091-- aspect. When we need to know the difference (e.g. to know what set of 2092-- check policies apply, use this flag and Has_Dynamic_Predicate_Aspect 2093-- to determine which case we have). 2094 2095-- Has_Storage_Size_Clause (Flag23) [implementation base type only] 2096-- Defined in task types and access types. It is set if a Storage_Size 2097-- clause is present for the type. Used to prevent multiple clauses for 2098-- one type. Note that this flag is initially cleared for a derived type 2099-- even though the Storage_Size for such a type is inherited from a 2100-- Storage_Size clause given for the parent type. Note that in the case 2101-- of access types, this flag is defined only in the root type, since a 2102-- storage size clause cannot be given to a derived type. 2103 2104-- Has_Stream_Size_Clause (Flag184) 2105-- Defined in all entities. It is set for types which have a Stream_Size 2106-- clause attribute. Used to prevent multiple Stream_Size clauses for a 2107-- given entity, and also whether it is necessary to check for a stream 2108-- size clause. 2109 2110-- Has_Task (Flag30) [base type only] 2111-- Defined in all type entities. Set on task types themselves, and also 2112-- (recursively) on any composite type which has a component for which 2113-- Has_Task is set. The meaning is that an allocator or declaration of 2114-- such an object must create the required tasks. Note: the flag is not 2115-- set on access types, even if they designate an object that Has_Task. 2116 2117-- Has_Timing_Event (Flag289) [base type only] 2118-- Defined in all type entities. Set on language defined type 2119-- Ada.Real_Time.Timing_Events.Timing_Event, and also (recursively) on 2120-- any composite type which has a component for which Has_Timing_Event 2121-- is set. Used for the No_Local_Timing_Event restriction. 2122 2123-- Has_Thunks (Flag228) 2124-- Applies to E_Constant entities marked Is_Tag. True for secondary tag 2125-- referencing a dispatch table whose contents are pointers to thunks. 2126 2127-- Has_Unchecked_Union (Flag123) [base type only] 2128-- Defined in all type entities. Set on unchecked unions themselves 2129-- and (recursively) on any composite type which has a component for 2130-- which Has_Unchecked_Union is set. The meaning is that a comparison 2131-- operation or 'Valid_Scalars reference for the type is not permitted. 2132-- Note that the flag is not set on access types, even if they designate 2133-- an object that has the flag Has_Unchecked_Union set. 2134 2135-- Has_Unknown_Discriminants (Flag72) 2136-- Defined in all entities. Set for types with unknown discriminants. 2137-- Types can have unknown discriminants either from their declaration or 2138-- through type derivation. The use of this flag exactly meets the spec 2139-- in RM 3.7(26). Note that all class-wide types are considered to have 2140-- unknown discriminants. Note that both flags Has_Discriminants and 2141-- Has_Unknown_Discriminants may be true for a type. Class-wide types and 2142-- their subtypes have unknown discriminants and can have declared ones 2143-- as well. Private types declared with unknown discriminants may have a 2144-- full view that has explicit discriminants, and both flag will be set 2145-- on the partial view, to ensure that discriminants are properly 2146-- inherited in certain contexts. 2147 2148-- Has_Visible_Refinement (Flag263) 2149-- Defined in E_Abstract_State entities. Set when a state has at least 2150-- one refinement constituent and analysis is in the region between 2151-- pragma Refined_State and the end of the package body declarations. 2152 2153-- Has_Volatile_Components (Flag87) [implementation base type only] 2154-- Defined in all types and objects. Set only for an array type or array 2155-- object if a valid pragma Volatile_Components or a valid pragma 2156-- Atomic_Components applies to the type or object. Note that in the case 2157-- of an object, this flag is only set on the object if there was an 2158-- explicit pragma for the object. In other words, the proper test for 2159-- whether an object has volatile components is to see if either the 2160-- object or its base type has this flag set. Note that in the case of a 2161-- type the pragma will be chained to the rep item chain of the first 2162-- subtype in the usual manner. 2163 2164-- Has_Xref_Entry (Flag182) 2165-- Defined in all entities. Set if an entity has an entry in the Xref 2166-- information generated in ali files. This is true for all source 2167-- entities in the extended main source file. It is also true of entities 2168-- in other packages that are referenced directly or indirectly from the 2169-- main source file (indirect reference occurs when the main source file 2170-- references an entity with a type reference. See package Lib.Xref for 2171-- further details). 2172 2173-- Hiding_Loop_Variable (Node8) 2174-- Defined in variables. Set only if a variable of a discrete type is 2175-- hidden by a loop variable in the same local scope, in which case 2176-- the Hiding_Loop_Variable field of the hidden variable points to 2177-- the E_Loop_Parameter entity doing the hiding. Used in processing 2178-- warning messages if the hidden variable turns out to be unused 2179-- or is referenced without being set. 2180 2181-- Hidden_In_Formal_Instance (Elist30) 2182-- Defined on actuals for formal packages. Entities on the list are 2183-- formals that are hidden outside of the formal package when this 2184-- package is not declared with a box, or the formal itself is not 2185-- defaulted (see RM 12.7 (10)). Their visibility is restored on exit 2186-- from the current generic, because the actual for the formal package 2187-- may be used subsequently in the current unit. 2188 2189-- Homonym (Node4) 2190-- Defined in all entities. Link for list of entities that have the 2191-- same source name and that are declared in the same or enclosing 2192-- scopes. Homonyms in the same scope are overloaded. Used for name 2193-- resolution and for the generation of debugging information. 2194 2195-- Ignore_SPARK_Mode_Pragmas (Flag301) 2196-- Present in concurrent type, entry, operator, [generic] package, 2197-- package body, [generic] subprogram, and subprogram body entities. 2198-- Set when the entity appears in an instance subject to SPARK_Mode 2199-- "off" and indicates that all SPARK_Mode pragmas found within must 2200-- be ignored. 2201 2202-- Implementation_Base_Type (synthesized) 2203-- Applies to all entities. For types, similar to Base_Type, but never 2204-- returns a private type when applied to a non-private type. Instead in 2205-- this case, it always returns the Underlying_Type of the base type, so 2206-- that we still have a concrete type. For entities other than types, 2207-- returns the entity unchanged. 2208 2209-- Import_Pragma (Node35) 2210-- Defined in subprogram entities. Set if a valid pragma Import or pragma 2211-- Import_Function or pragma Import_Procedure applies to the subprogram, 2212-- in which case this field points to the pragma (we can't use the normal 2213-- Rep_Item chain mechanism, because a single pragma Import can apply 2214-- to multiple subprogram entities). 2215 2216-- In_Package_Body (Flag48) 2217-- Defined in package entities. Set on the entity that denotes the 2218-- package (the defining occurrence of the package declaration) while 2219-- analyzing and expanding the package body. Reset on completion of 2220-- analysis/expansion. 2221 2222-- In_Private_Part (Flag45) 2223-- Defined in all entities. Can be set only in package entities and 2224-- objects. For package entities, this flag is set to indicate that the 2225-- private part of the package is being analyzed. The flag is reset at 2226-- the end of the package declaration. For objects it indicates that the 2227-- declaration of the object occurs in the private part of a package. 2228 2229-- Incomplete_Actuals (Elist24) 2230-- Defined on package entities that are instances. Indicates the actuals 2231-- types in the instantiation that are limited views. If this list is 2232-- not empty, the instantiation, which appears in a package declaration, 2233-- is relocated to the corresponding package body, which must have a 2234-- corresponding nonlimited with_clause. 2235 2236-- Initialization_Statements (Node28) 2237-- Defined in constants and variables. For a composite object initialized 2238-- initialized with an aggregate that has been converted to a sequence 2239-- of assignments, points to a block statement containing the 2240-- assignments. 2241 2242-- Inner_Instances (Elist23) 2243-- Defined in generic units. Contains element list of units that are 2244-- instantiated within the given generic. Used to diagnose circular 2245-- instantiations. 2246 2247-- Interface_Alias (Node25) 2248-- Defined in subprograms that cover a primitive operation of an abstract 2249-- interface type. Can be set only if the Is_Hidden flag is also set, 2250-- since such entities are always hidden. Points to its associated 2251-- interface subprogram. It is used to register the subprogram in 2252-- secondary dispatch table of the interface (Ada 2005: AI-251). 2253 2254-- Interface_Name (Node21) 2255-- Defined in constants, variables, exceptions, functions, procedures, 2256-- and packages. Set to Empty unless an export, import, or interface name 2257-- pragma has explicitly specified an external name, in which case it 2258-- references an N_String_Literal node for the specified external name. 2259-- Note that if this field is Empty, and Is_Imported or Is_Exported is 2260-- set, then the default interface name is the name of the entity, cased 2261-- in a manner that is appropriate to the system in use. Note that 2262-- Interface_Name is ignored if an address clause is present (since it 2263-- is meaningless in this case). 2264 2265-- Interfaces (Elist25) 2266-- Defined in record types and subtypes. List of abstract interfaces 2267-- implemented by a tagged type that are not already implemented by the 2268-- ancestors (Ada 2005: AI-251). 2269 2270-- Invariants_Ignored (Flag308) 2271-- Defined on all types. Indicates whether the type declaration is in 2272-- a context where Assertion_Policy is Ignore, in which case no checks 2273-- (static or dynamic) must be generated for objects of the type. 2274 2275-- Invariant_Procedure (synthesized) 2276-- Defined in types and subtypes. Set for private types and their full 2277-- views if one or more [class-wide] invariants apply to the type, or 2278-- when the type inherits class-wide invariants from a parent type or 2279-- an interface, or when the type is an array and its component type is 2280-- subject to an invariant, or when the type is record and contains a 2281-- component subject to an invariant (property is recursive). Points to 2282-- to the entity for a procedure which checks all these invariants. The 2283-- invariant procedure takes a single argument of the given type, and 2284-- returns if the invariant holds, or raises exception Assertion_Error 2285-- with an appropriate message if it does not hold. This attribute is 2286-- defined but always Empty for private subtypes. 2287 2288-- Note: the reason this is marked as a synthesized attribute is that the 2289-- way this is stored is as an element of the Subprograms_For_Type field. 2290 2291-- In_Use (Flag8) 2292-- Defined in packages and types. Set when analyzing a use clause for 2293-- the corresponding entity. Reset at end of corresponding declarative 2294-- part. The flag on a type is also used to determine the visibility of 2295-- the primitive operators of the type. 2296 2297-- Is_Abstract_Subprogram (Flag19) 2298-- Defined in all subprograms and entries. Set for abstract subprograms. 2299-- Always False for enumeration literals and entries. See also 2300-- Requires_Overriding. 2301 2302-- Is_Abstract_Type (Flag146) 2303-- Defined in all types. Set for abstract types. 2304 2305-- Is_Access_Constant (Flag69) 2306-- Defined in access types and subtypes. Indicates that the keyword 2307-- constant was present in the access type definition. 2308 2309-- Is_Access_Protected_Subprogram_Type (synthesized) 2310-- Applies to all types, true for named and anonymous access to 2311-- protected subprograms. 2312 2313-- Is_Access_Type (synthesized) 2314-- Applies to all entities, true for access types and subtypes 2315 2316-- Is_Activation_Record (Flag305) 2317-- Applies to E_In_Parameters generated in Exp_Unst for nested 2318-- subprograms, to mark the added formal that carries the activation 2319-- record created in the enclosing subprogram. 2320 2321-- Is_Actual_Subtype (Flag293) 2322-- Defined on all types, true for the generated constrained subtypes 2323-- that are built for unconstrained composite actuals. 2324 2325-- Is_Ada_2005_Only (Flag185) 2326-- Defined in all entities, true if a valid pragma Ada_05 or Ada_2005 2327-- applies to the entity which specifically names the entity, indicating 2328-- that the entity is Ada 2005 only. Note that this flag is not set if 2329-- the entity is part of a unit compiled with the normal no-argument form 2330-- of pragma Ada_05 or Ada_2005. 2331 2332-- Is_Ada_2012_Only (Flag199) 2333-- Defined in all entities, true if a valid pragma Ada_12 or Ada_2012 2334-- applies to the entity which specifically names the entity, indicating 2335-- that the entity is Ada 2012 only. Note that this flag is not set if 2336-- the entity is part of a unit compiled with the normal no-argument form 2337-- of pragma Ada_12 or Ada_2012. 2338 2339-- Is_Aliased (Flag15) 2340-- Defined in all entities. Set for objects and types whose declarations 2341-- carry the keyword aliased, and on record components that have the 2342-- keyword. For Ada 2012, also applies to formal parameters. 2343 2344-- Is_Array_Type (synthesized) 2345-- Applies to all entities, true for array types and subtypes 2346 2347-- Is_Asynchronous (Flag81) 2348-- Defined in all type entities and in procedure entities. Set 2349-- if a pragma Asynchronous applies to the entity. 2350 2351-- Is_Atomic (Flag85) 2352-- Defined in all type entities, and also in constants, components, and 2353-- variables. Set if a pragma Atomic or Shared applies to the entity. 2354-- In the case of private and incomplete types, this flag is set in 2355-- both the partial view and the full view. 2356 2357-- Is_Atomic_Or_VFA (synth) 2358-- Defined in all type entities, and also in constants, components and 2359-- variables. Set if a pragma Atomic or Shared or Volatile_Full_Access 2360-- applies to the entity. For many purposes VFA objects should be treated 2361-- the same as Atomic objects, and this predicate is intended for that 2362-- usage. In the case of private and incomplete types, the predicate 2363-- applies to both the partial view and the full view. 2364 2365-- Is_Base_Type (synthesized) 2366-- Applies to type and subtype entities. True if entity is a base type. 2367 2368-- Is_Bit_Packed_Array (Flag122) [implementation base type only] 2369-- Defined in all entities. This flag is set for a packed array type that 2370-- is bit-packed (i.e. the component size is known by the front end and 2371-- is in the range 1-63 but not a multiple of 8). Is_Packed is always set 2372-- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be 2373-- set without Is_Bit_Packed_Array if the component size is not known by 2374-- the front-end or for the case of an array having one or more index 2375-- types that are enumeration types with non-standard representation. 2376 2377-- Is_Boolean_Type (synthesized) 2378-- Applies to all entities, true for boolean types and subtypes, 2379-- i.e. Standard.Boolean and all types ultimately derived from it. 2380 2381-- Is_Called (Flag102) 2382-- Defined in subprograms and packages. Set if a subprogram is called 2383-- from the unit being compiled or a unit in the closure. Also set for 2384-- a package that contains called subprograms. Used only for inlining. 2385 2386-- Is_Character_Type (Flag63) 2387-- Defined in all entities. Set for character types and subtypes, 2388-- i.e. enumeration types that have at least one character literal. 2389 2390-- Is_Checked_Ghost_Entity (Flag277) 2391-- Applies to all entities. Set for abstract states, [generic] packages, 2392-- [generic] subprograms, components, discriminants, formal parameters, 2393-- objects, package bodies, subprogram bodies, and [sub]types subject to 2394-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2395-- subject to Assertion_Policy Ghost => Check. 2396 2397-- Is_Child_Unit (Flag73) 2398-- Defined in all entities. Set only for defining entities of program 2399-- units that are child units (but False for subunits). 2400 2401-- Is_Class_Wide_Clone (Flag290) 2402-- Defined on subprogram entities. Set for subprograms built in order 2403-- to implement properly the inheritance of class-wide pre- or post- 2404-- conditions when the condition contains calls to other primitives 2405-- of the ancestor type. Used to implement AI12-0195. 2406 2407-- Is_Class_Wide_Equivalent_Type (Flag35) 2408-- Defined in record types and subtypes. Set to True, if the type acts 2409-- as a class-wide equivalent type, i.e. the Equivalent_Type field of 2410-- some class-wide subtype entity references this record type. 2411 2412-- Is_Class_Wide_Type (synthesized) 2413-- Applies to all entities, true for class wide types and subtypes 2414 2415-- Is_Compilation_Unit (Flag149) 2416-- Defined in all entities. Set if the entity is a package or subprogram 2417-- entity for a compilation unit other than a subunit (since we treat 2418-- subunits as part of the same compilation operation as the ultimate 2419-- parent, we do not consider them to be separate units for this flag). 2420 2421-- Is_Completely_Hidden (Flag103) 2422-- Defined on discriminants. Only set on girder discriminants of 2423-- untagged types. When set, the entity is a girder discriminant of a 2424-- derived untagged type which is not directly visible in the derived 2425-- type because the derived type or one of its ancestors have renamed the 2426-- discriminants in the root type. Note: there are girder discriminants 2427-- which are not Completely_Hidden (e.g. discriminants of a root type). 2428 2429-- Is_Composite_Type (synthesized) 2430-- Applies to all entities, true for all composite types and subtypes. 2431-- Either Is_Composite_Type or Is_Elementary_Type (but not both) is true 2432-- of any type. 2433 2434-- Is_Concurrent_Record_Type (Flag20) 2435-- Defined in record types and subtypes. Set if the type was created 2436-- by the expander to represent a task or protected type. For every 2437-- concurrent type, such as record type is constructed, and task and 2438-- protected objects are instances of this record type at run time 2439-- (The backend will replace declarations of the concurrent type using 2440-- the declarations of the corresponding record type). See Exp_Ch9 for 2441-- further details. 2442 2443-- Is_Concurrent_Type (synthesized) 2444-- Applies to all entities, true for task types and subtypes and for 2445-- protected types and subtypes. 2446 2447-- Is_Constant_Object (synthesized) 2448-- Applies to all entities, true for E_Constant, E_Loop_Parameter, and 2449-- E_In_Parameter entities. 2450 2451-- Is_Constrained (Flag12) 2452-- Defined in types or subtypes which may have index, discriminant 2453-- or range constraint (i.e. array types and subtypes, record types 2454-- and subtypes, string types and subtypes, and all numeric types). 2455-- Set if the type or subtype is constrained. 2456 2457-- Is_Constr_Subt_For_U_Nominal (Flag80) 2458-- Defined in all types and subtypes. Set only for the constructed 2459-- subtype of an object whose nominal subtype is unconstrained. Note 2460-- that the constructed subtype itself will be constrained. 2461 2462-- Is_Constr_Subt_For_UN_Aliased (Flag141) 2463-- Defined in all types and subtypes. This flag can be set only if 2464-- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in 2465-- addition the object concerned is aliased. This flag is used by 2466-- the backend to determine whether a template must be constructed. 2467 2468-- Is_Constructor (Flag76) 2469-- Defined in function and procedure entities. Set if a pragma 2470-- CPP_Constructor applies to the subprogram. 2471 2472-- Is_Controlled_Active (Flag42) [base type only] 2473-- Defined in all type entities. Indicates that the type is controlled, 2474-- i.e. is either a descendant of Ada.Finalization.Controlled or of 2475-- Ada.Finalization.Limited_Controlled. 2476 2477-- Is_Controlled (synth) [base type only] 2478-- Defined in all type entities. Set if Is_Controlled_Active is set for 2479-- the type, and Disable_Controlled is not set. 2480 2481-- Is_Controlling_Formal (Flag97) 2482-- Defined in all Formal_Kind entities. Marks the controlling parameters 2483-- of dispatching operations. 2484 2485-- Is_CPP_Class (Flag74) 2486-- Defined in all type entities, set only for tagged types to which a 2487-- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied. 2488 2489-- Is_Decimal_Fixed_Point_Type (synthesized) 2490-- Applies to all type entities, true for decimal fixed point 2491-- types and subtypes. 2492 2493-- Is_Descendant_Of_Address (Flag223) 2494-- Defined in all entities. True if the entity is type System.Address, 2495-- or (recursively) a subtype or derived type of System.Address. 2496 2497-- Is_DIC_Procedure (Flag132) 2498-- Defined in functions and procedures. Set for a generated procedure 2499-- which verifies the assumption of pragma Default_Initial_Condition at 2500-- run time. 2501 2502-- Is_Discrete_Or_Fixed_Point_Type (synthesized) 2503-- Applies to all entities, true for all discrete types and subtypes 2504-- and all fixed-point types and subtypes. 2505 2506-- Is_Discrete_Type (synthesized) 2507-- Applies to all entities, true for all discrete types and subtypes 2508 2509-- Is_Discrim_SO_Function (Flag176) 2510-- Defined in all entities.

Set only in E_Function entities for functions 2515-- created to do discriminant checks. 2516 2517-- Is_Discriminal (synthesized) 2518-- Applies to all entities, true for renamings of discriminants. Such 2519-- entities appear as constants or IN parameters. 2520 2521-- Is_Dispatch_Table_Entity (Flag234) 2522-- Applies to all entities. Set to indicate to the backend that this 2523-- entity is associated with a dispatch table. 2524 2525-- Is_Dispatching_Operation (Flag6) 2526-- Defined in all entities. Set for procedures, functions, generic 2527-- procedures, and generic functions if the corresponding operation 2528-- is dispatching. 2529 2530-- Is_Dynamic_Scope (synthesized) 2531-- Applies to all Entities. Returns True if the entity is a dynamic 2532-- scope (i.e. a block, subprogram, task_type, entry or extended return 2533-- statement). 2534 2535-- Is_Elaboration_Checks_OK_Id (Flag148) 2536-- Defined in elaboration targets (see terminology in Sem_Elab). Set when 2537-- the target appears in a region which is subject to elabled elaboration 2538-- checks. Such targets are allowed to generate run-time conditional ABE 2539-- checks or guaranteed ABE failures. 2540 2541-- Is_Elaboration_Target (synthesized) 2542-- Applies to all entities, True only for elaboration targets (see the 2543-- terminology in Sem_Elab). 2544 2545-- Is_Elaboration_Warnings_OK_Id (Flag304) 2546-- Defined in elaboration targets (see terminology in Sem_Elab). Set when 2547-- the target appears in a region with elaboration warnings enabled. 2548 2549-- Is_Elementary_Type (synthesized) 2550-- Applies to all entities, True for all elementary types and subtypes. 2551-- Either Is_Composite_Type or Is_Elementary_Type (but not both) is true 2552-- of any type. 2553 2554-- Is_Eliminated (Flag124) 2555-- Defined in type entities, subprogram entities, and object entities. 2556-- Indicates that the corresponding entity has been eliminated by use 2557-- of pragma Eliminate. Also used to mark subprogram entities whose 2558-- declaration and body are within unreachable code that is removed. 2559 2560-- Is_Entry (synthesized) 2561-- Applies to all entities, True only for entry and entry family 2562-- entities and False for all other entity kinds. 2563 2564-- Is_Entry_Formal (Flag52) 2565-- Defined in all entities. Set only for entry formals (which can only 2566-- be in, in-out or out parameters). This flag is used to speed up the 2567-- test for the need to replace references in Exp_Ch2. 2568 2569-- Is_Entry_Wrapper (Flag297) 2570-- Defined on wrappers created for entries that have precondition aspects 2571 2572-- Is_Enumeration_Type (synthesized) 2573-- Defined in all entities, true for enumeration types and subtypes 2574 2575-- Is_Exception_Handler (Flag286) 2576-- Defined in blocks. Set if the block serves only as a scope of an 2577-- exception handler with a choice parameter. Such a block does not 2578-- physically appear in the tree. 2579 2580-- Is_Exported (Flag99) 2581-- Defined in all entities. Set if the entity is exported. For now we 2582-- only allow the export of constants, exceptions, functions, procedures 2583-- and variables, but that may well change later on. Exceptions can only 2584-- be exported in the Java VM implementation of GNAT, which is retired. 2585 2586-- Is_External_State (synthesized) 2587-- Applies to all entities, true for abstract states that are subject to 2588-- option External or Synchronous. 2589 2590-- Is_Finalized_Transient (Flag252) 2591-- Defined in constants, loop parameters of generalized iterators, and 2592-- variables. Set when a transient object has been finalized by one of 2593-- the transient finalization mechanisms. The flag prevents the double 2594-- finalization of the object. 2595 2596-- Is_Finalizer (synthesized) 2597-- Applies to all entities, true for procedures containing finalization 2598-- code to process local or library level objects. 2599 2600-- Is_First_Subtype (Flag70) 2601-- Defined in all entities. True for first subtypes (RM 3.2.1(6)), 2602-- i.e. the entity in the type declaration that introduced the type. 2603-- This may be the base type itself (e.g. for record declarations and 2604-- enumeration type declarations), or it may be the first subtype of 2605-- an anonymous base type (e.g. for integer type declarations or 2606-- constrained array declarations). 2607 2608-- Is_Fixed_Point_Type (synthesized) 2609-- Applies to all entities, true for decimal and ordinary fixed 2610-- point types and subtypes. 2611 2612-- Is_Floating_Point_Type (synthesized) 2613-- Applies to all entities, true for float types and subtypes 2614 2615-- Is_Formal (synthesized) 2616-- Applies to all entities, true for IN, IN OUT and OUT parameters 2617 2618-- Is_Formal_Object (synthesized) 2619-- Applies to all entities, true for generic IN and IN OUT parameters 2620 2621-- Is_Formal_Subprogram (Flag111) 2622-- Defined in all entities. Set for generic formal subprograms. 2623 2624-- Is_Frozen (Flag4) 2625-- Defined in all type and subtype entities. Set if type or subtype has 2626-- been frozen. 2627 2628-- Is_Generic_Actual_Subprogram (Flag274) 2629-- Defined on functions and procedures. Set on the entity of the renaming 2630-- declaration created within an instance for an actual subprogram. 2631-- Used to generate constraint checks on calls to these subprograms, even 2632-- within an instance of a predefined run-time unit, in which checks 2633-- are otherwise suppressed. 2634-- 2635-- The flag is also set on the entity of the expression function created 2636-- within an instance, for a function that has external axiomatization, 2637-- for use in GNATprove mode. 2638 2639-- Is_Generic_Actual_Type (Flag94) 2640-- Defined in all type and subtype entities. Set in the subtype 2641-- declaration that renames the generic formal as a subtype of the 2642-- actual. Guarantees that the subtype is not static within the instance. 2643-- Also used during analysis of an instance, to simplify resolution of 2644-- accidental overloading that occurs when different formal types get the 2645-- same actual. 2646 2647-- Is_Generic_Instance (Flag130) 2648-- Defined in all entities. Set to indicate that the entity is an 2649-- instance of a generic unit, or a formal package (which is an instance 2650-- of the template). 2651 2652-- Is_Generic_Subprogram (synthesized) 2653-- Applies to all entities. Yields True for a generic subprogram 2654-- (generic function, generic subprogram), False for all other entities. 2655 2656-- Is_Generic_Type (Flag13) 2657-- Defined in all entities. Set for types which are generic formal types. 2658-- Such types have an Ekind that corresponds to their classification, so 2659-- the Ekind cannot be used to identify generic formal types. 2660 2661-- Is_Generic_Unit (synthesized) 2662-- Applies to all entities. Yields True for a generic unit (generic 2663-- package, generic function, generic procedure), and False for all 2664-- other entities. 2665 2666-- Is_Ghost_Entity (synthesized) 2667-- Applies to all entities. Yields True for abstract states, [generic] 2668-- packages, [generic] subprograms, components, discriminants, formal 2669-- parameters, objects, package bodies, subprogram bodies, and [sub]types 2670-- subject to pragma Ghost or those that inherit the Ghost property from 2671-- an enclosing construct. 2672 2673-- Is_Hidden (Flag57) 2674-- Defined in all entities. Set for all entities declared in the 2675-- private part or body of a package. Also marks generic formals of a 2676-- formal package declared without a box. For library level entities, 2677-- this flag is set if the entity is not publicly visible. This flag 2678-- is reset when compiling the body of the package where the entity 2679-- is declared, when compiling the private part or body of a public 2680-- child unit, and when compiling a private child unit (see Install_ 2681-- Private_Declaration in sem_ch7). 2682 2683-- Is_Hidden_Non_Overridden_Subpgm (Flag2) 2684-- Defined in all entities. Set for implicitly declared subprograms 2685-- that require overriding or are null procedures, and are hidden by 2686-- a non-fully conformant homograph with the same characteristics 2687-- (Ada RM 8.3 12.3/2). 2688 2689-- Is_Hidden_Open_Scope (Flag171) 2690-- Defined in all entities. Set for a scope that contains the 2691-- instantiation of a child unit, and whose entities are not visible 2692-- during analysis of the instance. 2693 2694-- Is_Ignored_Ghost_Entity (Flag278) 2695-- Applies to all entities. Set for abstract states, [generic] packages, 2696-- [generic] subprograms, components, discriminants, formal parameters, 2697-- objects, package bodies, subprogram bodies, and [sub]types subject to 2698-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2699-- subject to Assertion_Policy Ghost => Ignore. 2700 2701-- Is_Ignored_Transient (Flag295) 2702-- Defined in constants, loop parameters of generalized iterators, and 2703-- variables. Set when a transient object must be processed by one of 2704-- the transient finalization mechanisms. Once marked, a transient is 2705-- intentionally ignored by the general finalization mechanism because 2706-- its clean up actions are context specific. 2707 2708-- Is_Immediately_Visible (Flag7) 2709-- Defined in all entities. Set if entity is immediately visible, i.e. 2710-- is defined in some currently open scope (RM 8.3(4)). 2711 2712-- Is_Implementation_Defined (Flag254) 2713-- Defined in all entities. Set if a pragma Implementation_Defined is 2714-- applied to the pragma. Used to mark all implementation defined 2715-- identifiers in standard library packages, and to implement the 2716-- restriction No_Implementation_Identifiers. 2717 2718-- Is_Imported (Flag24) 2719-- Defined in all entities. Set if the entity is imported. For now we 2720-- only allow the import of exceptions, functions, procedures, packages, 2721-- constants, and variables. Exceptions, packages, and types can only be 2722-- imported in the Java VM implementation, which is retired. 2723 2724-- Is_Incomplete_Or_Private_Type (synthesized) 2725-- Applies to all entities, true for private and incomplete types 2726 2727-- Is_Incomplete_Type (synthesized) 2728-- Applies to all entities, true for incomplete types and subtypes 2729 2730-- Is_Independent (Flag268) 2731-- Defined in all types and objects. Set if a valid pragma or aspect 2732-- Independent applies to the entity, or for a component if a valid 2733-- pragma or aspect Independent_Components applies to the enclosing 2734-- record type. Also set if a pragma Shared or pragma Atomic applies to 2735-- the entity, or if the declaration of the entity carries the Aliased 2736-- keyword. For Ada 2012, also applies to formal parameters. In the 2737-- case of private and incomplete types, this flag is set in both the 2738-- partial view and the full view. 2739 2740-- Is_Initial_Condition_Procedure (Flag302) 2741-- Defined in functions and procedures. Set for a generated procedure 2742-- which verifies the assumption of pragma Initial_Condition at run time. 2743 2744-- Is_Inlined (Flag11) 2745-- Defined in all entities. Set for functions and procedures which are 2746-- to be inlined. For subprograms created during expansion, this flag 2747-- may be set directly by the expander to request inlining. Also set 2748-- for packages that contain inlined subprograms, whose bodies must be 2749-- be compiled. Is_Inlined is also set on generic subprograms and is 2750-- inherited by their instances. It is also set on the body entities 2751-- of inlined subprograms. See also Has_Pragma_Inline. 2752 2753-- Is_Inlined_Always (Flag1) 2754-- Defined in subprograms. Set for functions and procedures which are 2755-- always inlined in GNATprove mode. GNATprove uses this flag to know 2756-- when a body does not need to be analyzed. The value of this flag is 2757-- only meaningful if Body_To_Inline is not Empty for the subprogram. 2758 2759-- Is_Instantiated (Flag126) 2760-- Defined in generic packages and generic subprograms. Set if the unit 2761-- is instantiated from somewhere in the extended main source unit. This 2762-- flag is used to control warnings about the unit being uninstantiated. 2763-- Also set in a package that is used as an actual for a generic package 2764-- formal in an instantiation. Also set on a parent instance, in the 2765-- instantiation of a child, which is implicitly declared in the parent. 2766 2767-- Is_Integer_Type (synthesized) 2768-- Applies to all entities, true for integer types and subtypes 2769 2770-- Is_Interface (Flag186) 2771-- Defined in record types and subtypes. Set to indicate that the current 2772-- entity corresponds to an abstract interface. Because abstract 2773-- interfaces are conceptually a special kind of abstract tagged type 2774-- we represent them by means of tagged record types and subtypes 2775-- marked with this attribute. This allows us to reuse most of the 2776-- compiler support for abstract tagged types to implement interfaces 2777-- (Ada 2005: AI-251). 2778 2779-- Is_Internal (Flag17) 2780-- Defined in all entities. Set to indicate an entity created during 2781-- semantic processing (e.g. an implicit type, or a temporary). The 2782-- current uses of this flag are: 2783-- 2784-- 1) Internal entities (such as temporaries generated for the result 2785-- of an inlined function call or dummy variables generated for the 2786-- debugger). Set to indicate that they need not be initialized, even 2787-- when scalars are initialized or normalized. 2788-- 2789-- 2) Predefined primitives of tagged types. Set to mark that they 2790-- have specific properties: first they are primitives even if they 2791-- are not defined in the type scope (the freezing point is not 2792-- necessarily in the same scope), and second the predefined equality 2793-- can be overridden by a user-defined equality, no body will be 2794-- generated in this case. 2795-- 2796-- 3) Object declarations generated by the expander that are implicitly 2797-- imported or exported so that they can be marked in Sprint output. 2798-- 2799-- 4) Internal entities in the list of primitives of tagged types that 2800-- are used to handle secondary dispatch tables. These entities have 2801-- also the attribute Interface_Alias. 2802 2803-- Is_Interrupt_Handler (Flag89) 2804-- Defined in procedures. Set if a pragma Interrupt_Handler applies 2805-- to the procedure. The procedure must be parameterless, and on all 2806-- targets except AAMP it must be a protected procedure. 2807 2808-- Is_Intrinsic_Subprogram (Flag64) 2809-- Defined in functions and procedures. It is set if a valid pragma 2810-- Interface or Import is present for this subprogram specifying 2811-- convention Intrinsic. Valid means that the name and profile of the 2812-- subprogram match the requirements of one of the recognized intrinsic 2813-- subprograms (see package Sem_Intr for details). Note: the value of 2814-- Convention for such an entity will be set to Convention_Intrinsic, 2815-- but it is the setting of Is_Intrinsic_Subprogram, NOT simply having 2816-- convention set to intrinsic, which causes intrinsic code to be 2817-- generated. 2818 2819-- Is_Invariant_Procedure (Flag257) 2820-- Defined in functions and procedures. Set for a generated invariant 2821-- procedure which verifies the invariants of both the partial and full 2822-- views of a private type or private extension as well as any inherited 2823-- class-wide invariants from parent types or interfaces. 2824 2825-- Is_Itype (Flag91) 2826-- Defined in all entities. Set to indicate that a type is an Itype, 2827-- which means that the declaration for the type does not appear 2828-- explicitly in the tree. Instead the backend will elaborate the type 2829-- when it is first used. Has_Delayed_Freeze can be set for Itypes, and 2830-- the meaning is that the first use (the one which causes the type to be 2831-- defined) will be the freeze node. Note that an important restriction 2832-- on Itypes is that the first use of such a type (the one that causes it 2833-- to be defined) must be in the same scope as the type. 2834 2835-- Is_Known_Non_Null (Flag37) 2836-- Defined in all entities. Relevant (and can be set) only for 2837-- objects of an access type. It is set if the object is currently 2838-- known to have a non-null value (meaning that no access checks 2839-- are needed). The indication can for example come from assignment 2840-- of an access parameter or an allocator whose value is known non-null. 2841-- 2842-- Note: this flag is set according to the sequential flow of the 2843-- program, watching the current value of the variable. However, this 2844-- processing can miss cases of changing the value of an aliased or 2845-- constant object, so even if this flag is set, it should not be 2846-- believed if the variable is aliased or volatile. It would be a 2847-- little neater to avoid the flag being set in the first place in 2848-- such cases, but that's trickier, and there is only one place that 2849-- tests the value anyway. 2850-- 2851-- The flag is dynamically set and reset as semantic analysis and 2852-- expansion proceeds. Its value is meaningless once the tree is 2853-- fully constructed, since it simply indicates the last state. 2854-- Thus this flag has no meaning to the backend. 2855 2856-- Is_Known_Null (Flag204) 2857-- Defined in all entities. Relevant (and can be set ) only for 2858-- objects of an access type. It is set if the object is currently known 2859-- to have a null value (meaning that a dereference will surely raise 2860-- constraint error exception). The indication can come from an 2861-- assignment or object declaration. 2862-- 2863-- The comments above about sequential flow and aliased and volatile for 2864-- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag. 2865 2866-- Is_Known_Valid (Flag170) 2867-- Defined in all entities. Relevant for types (and subtype) and 2868-- for objects (and enumeration literals) of a discrete type. 2869-- 2870-- The purpose of this flag is to implement the requirement stated 2871-- in (RM 13.9.1(9-11)) which require that the use of possibly invalid 2872-- values may not cause programs to become erroneous. See the function 2873-- Checks.Expr_Known_Valid for further details. Note that the setting 2874-- is conservative, in the sense that if the flag is set, it must be 2875-- right. If the flag is not set, nothing is known about the validity. 2876-- 2877-- For enumeration literals, the flag is always set, since clearly 2878-- an enumeration literal represents a valid value. Range checks 2879-- where necessary will ensure that this valid value is appropriate. 2880-- 2881-- For objects, the flag indicates the state of knowledge about the 2882-- current value of the object. This may be modified during expansion, 2883-- and thus the final value is not relevant to the backend. 2884-- 2885-- For types and subtypes, the flag is set if all possible bit patterns 2886-- of length Object_Size (i.e. Esize of the type) represent valid values 2887-- of the type. In general for such types, all values are valid, the 2888-- only exception being the case where an object of the type has an 2889-- explicit size that is greater than Object_Size. 2890-- 2891-- For non-discrete objects, the setting of the Is_Known_Valid flag is 2892-- not defined, and is not relevant, since the considerations of the 2893-- requirement in (RM 13.9.1(9-11)) do not apply. 2894-- 2895-- The flag is dynamically set and reset as semantic analysis and 2896-- expansion proceeds. Its value is meaningless once the tree is 2897-- fully constructed, since it simply indicates the last state. 2898-- Thus this flag has no meaning to the backend. 2899 2900-- Is_Limited_Composite (Flag106) 2901-- Defined in all entities. Set for composite types that have a limited 2902-- component. Used to enforce the rule that operations on the composite 2903-- type that depend on the full view of the component do not become 2904-- visible until the immediate scope of the composite type itself 2905-- (RM 7.3.1 (5)). 2906 2907-- Is_Limited_Interface (Flag197) 2908-- Defined in record types and subtypes. True for interface types, if 2909-- interface is declared limited, task, protected, or synchronized, or 2910-- is derived from a limited interface. 2911 2912-- Is_Limited_Record (Flag25) 2913-- Defined in all entities. Set to true for record (sub)types if the 2914-- record is declared to be limited. Note that this flag is not set 2915-- simply because some components of the record are limited. 2916 2917-- Is_Local_Anonymous_Access (Flag194) 2918-- Defined in access types. Set for an anonymous access type to indicate 2919-- that the type is created for a record component with an access 2920-- definition, an array component, or (pre-Ada 2012) a standalone object. 2921-- Such anonymous types have an accessibility level equal to that of the 2922-- declaration in which they appear, unlike the anonymous access types 2923-- that are created for access parameters, access discriminants, and 2924-- (as of Ada 2012) stand-alone objects. 2925 2926-- Is_Loop_Parameter (Flag307) 2927-- Applies to all entities. Certain loops, in particular "for ... of" 2928-- loops, get transformed so that the loop parameter is declared by a 2929-- variable declaration, so the entity is an E_Variable. This is True for 2930-- such E_Variables; False otherwise. 2931 2932-- Is_Machine_Code_Subprogram (Flag137) 2933-- Defined in subprogram entities. Set to indicate that the subprogram 2934-- is a machine code subprogram (i.e. its body includes at least one 2935-- code statement). Also indicates that all necessary semantic checks 2936-- as required by RM 13.8(3) have been performed. 2937 2938-- Is_Modular_Integer_Type (synthesized) 2939-- Applies to all entities. True if entity is a modular integer type 2940 2941-- Is_Non_Static_Subtype (Flag109) 2942-- Defined in all type and subtype entities. It is set in some (but not 2943-- all) cases in which a subtype is known to be non-static. Before this 2944-- flag was added, the computation of whether a subtype was static was 2945-- entirely synthesized, by looking at the bounds, and the immediate 2946-- subtype parent. However, this method does not work for some Itypes 2947-- that have no parent set (and the only way to find the immediate 2948-- subtype parent is to go through the tree). For now, this flag is set 2949-- conservatively, i.e. if it is set then for sure the subtype is non- 2950-- static, but if it is not set, then the type may or may not be static. 2951-- Thus the test for a static subtype is that this flag is clear AND that 2952-- the bounds are static AND that the parent subtype (if available to be 2953-- tested) is static. Eventually we should make sure this flag is always 2954-- set right, at which point, these comments can be removed, and the 2955-- tests for static subtypes greatly simplified. 2956 2957-- Is_Null_Init_Proc (Flag178) 2958-- Defined in procedure entities. Set for generated init proc procedures 2959-- (used to initialize composite types), if the code for the procedure 2960-- is null (i.e. is a return and nothing else). Such null initialization 2961-- procedures are generated in case some client is compiled using the 2962-- Initialize_Scalars pragma, generating a call to this null procedure, 2963-- but there is no need to call such procedures within a compilation 2964-- unit, and this flag is used to suppress such calls. 2965 2966-- Is_Null_State (synthesized) 2967-- Applies to all entities, true for an abstract state declared with 2968-- keyword null. 2969 2970-- Is_Numeric_Type (synthesized) 2971-- Applies to all entities, true for all numeric types and subtypes 2972-- (integer, fixed, float). 2973 2974-- Is_Object (synthesized) 2975-- Applies to all entities, true for entities representing objects, 2976-- including generic formal parameters. 2977 2978-- Is_Obsolescent (Flag153) 2979-- Defined in all entities. Set for any entity to which a valid pragma 2980-- or aspect Obsolescent applies. 2981 2982-- Is_Only_Out_Parameter (Flag226) 2983-- Defined in formal parameter entities. Set if this parameter is the 2984-- only OUT parameter for this formal part. If there is more than one 2985-- out parameter, or if there is some other IN OUT parameter then this 2986-- flag is not set in any of them. Used in generation of warnings. 2987 2988-- Is_Ordinary_Fixed_Point_Type (synthesized) 2989-- Applies to all entities, true for ordinary fixed point types and 2990-- subtypes. 2991 2992-- Is_Package_Body_Entity (Flag160) 2993-- Defined in all entities. Set for entities defined at the top level 2994-- of a package body. Used to control externally generated names. 2995 2996-- Is_Package_Or_Generic_Package (synthesized) 2997-- Applies to all entities. True for packages and generic packages. 2998-- False for all other entities. 2999 3000-- Is_Packed (Flag51) [implementation base type only] 3001-- Defined in all type entities. This flag is set only for record and 3002-- array types which have a packed representation. There are four cases 3003-- which cause packing: 3004-- 3005-- 1. Explicit use of pragma Pack to pack a record. 3006-- 2. Explicit use of pragma Pack to pack an array. 3007-- 3. Setting Component_Size of an array to a packable value. 3008-- 4. Indexing an array with a non-standard enumeration type. 3009-- 3010-- For records, Is_Packed is always set if Has_Pragma_Pack is set, and 3011-- can also be set on its own in a derived type which inherited its 3012-- packed status. 3013-- 3014-- For arrays, Is_Packed is set if either Has_Pragma_Pack is set and the 3015-- component size is either not known at compile time or known but not 3016-- 8/16/32/64 bits, or a Component_Size clause exists and the specified 3017-- value is smaller than 64 bits but not 8/16/32, or if the array has one 3018-- or more index types that are enumeration types with a non-standard 3019-- representation (in GNAT, we store such arrays compactly, using the Pos 3020-- of the enumeration type value). As for the case of records, Is_Packed 3021-- can be set on its own for a derived type. 3022 3023-- Before an array type is frozen, Is_Packed will always be set if 3024-- Has_Pragma_Pack is set. Before the freeze point, it is not possible 3025-- to know the component size, since the component type is not frozen 3026-- until the array type is frozen. Thus Is_Packed for an array type 3027-- before it is frozen means that packed is required. Then if it turns 3028-- out that the component size doesn't require packing, the Is_Packed 3029-- flag gets turned off. 3030 3031-- In the bit-packed array case (i.e. the component size is known by the 3032-- front end and is in the range 1-63 but not a multiple of 8), then the 3033-- Is_Bit_Packed_Array flag will be set once the array type is frozen. 3034-- 3035-- Is_Packed_Array (synth) 3036-- Applies to all entities, true if entity is for a packed array. 3037 3038-- Is_Packed_Array_Impl_Type (Flag138) 3039-- Defined in all entities. This flag is set on the entity for the type 3040-- used to implement a packed array (either a modular type or a subtype 3041-- of Packed_Bytes{1,2,4} in the bit-packed array case, a regular array 3042-- in the non-standard enumeration index case). It is set if and only 3043-- if the type appears in the Packed_Array_Impl_Type field of some other 3044-- entity. It is used by the back end to activate the special processing 3045-- for such types (unchecked conversions that would not otherwise be 3046-- allowed are allowed for such types). If Is_Packed_Array_Impl_Type is 3047-- set in an entity, then the Original_Array_Type field of this entity 3048-- points to the array type for which this is the Packed_Array_Impl_Type. 3049 3050-- Is_Param_Block_Component_Type (Flag215) [base type only] 3051-- Defined in access types. Set to indicate that a type is the type of a 3052-- component of the parameter block record type generated by the compiler 3053-- for an entry or a select statement. Read by CodePeer. 3054 3055-- Is_Partial_Invariant_Procedure (Flag292) 3056-- Defined in functions and procedures. Set for a generated invariant 3057-- procedure which verifies the invariants of the partial view of a 3058-- private type or private extension. 3059 3060-- Is_Potentially_Use_Visible (Flag9) 3061-- Defined in all entities. Set if entity is potentially use visible, 3062-- i.e. it is defined in a package that appears in a currently active 3063-- use clause (RM 8.4(8)). Note that potentially use visible entities 3064-- are not necessarily use visible (RM 8.4(9-11)). 3065 3066-- Is_Predicate_Function (Flag255) 3067-- Present in functions and procedures. Set for generated predicate 3068-- functions. 3069 3070-- Is_Predicate_Function_M (Flag256) 3071-- Present in functions and procedures. Set for special version of 3072-- predicate function generated for use in membership tests, where 3073-- raise expressions are transformed to return False. 3074 3075-- Is_Preelaborated (Flag59) 3076-- Defined in all entities, set in E_Package and E_Generic_Package 3077-- entities to which a pragma Preelaborate is applied, and also in 3078-- all entities within such packages. Note that the fact that this 3079-- flag is set does not necesarily mean that no elaboration code is 3080-- generated for the package. 3081 3082-- Is_Primitive (Flag218) 3083-- Defined in overloadable entities and in generic subprograms. Set to 3084-- indicate that this is a primitive operation of some type, which may 3085-- be a tagged type or an untagged type. Used to verify overriding 3086-- indicators in bodies. 3087 3088-- Is_Primitive_Wrapper (Flag195) 3089-- Defined in functions and procedures created by the expander to serve 3090-- as an indirection mechanism to overriding primitives of concurrent 3091-- types, entries and protected procedures. 3092 3093-- Is_Prival (synthesized) 3094-- Applies to all entities, true for renamings of private protected 3095-- components. Such entities appear as constants or variables. 3096 3097-- Is_Private_Composite (Flag107) 3098-- Defined in composite types that have a private component. Used to 3099-- enforce the rule that operations on the composite type that depend 3100-- on the full view of the component, do not become visible until the 3101-- immediate scope of the composite type itself (7.3.1 (5)). Both this 3102-- flag and Is_Limited_Composite are needed. 3103 3104-- Is_Private_Descendant (Flag53) 3105-- Defined in entities that can represent library units (packages, 3106-- functions, procedures). Set if the library unit is itself a private 3107-- child unit, or if it is the descendant of a private child unit. 3108 3109-- Is_Private_Primitive (Flag245) 3110-- Defined in subprograms. Set if the operation is a primitive of a 3111-- tagged type (procedure or function dispatching on result) whose 3112-- full view has not been seen. Used in particular for primitive 3113-- subprograms of a synchronized type declared between the two views 3114-- of the type, so that the wrapper built for such a subprogram can 3115-- be given the proper signature. 3116 3117-- Is_Private_Type (synthesized) 3118-- Applies to all entities, true for private types and subtypes, 3119-- as well as for record with private types as subtypes. 3120 3121-- Is_Protected_Component (synthesized) 3122-- Applicable to all entities, true if the entity denotes a private 3123-- component of a protected type. 3124 3125-- Is_Protected_Interface (synthesized) 3126-- Defined in types that are interfaces. True if interface is declared 3127-- protected, or is derived from protected interfaces. 3128 3129-- Is_Protected_Record_Type (synthesized) 3130-- Applies to all entities, true if Is_Concurrent_Record_Type is true and 3131-- Corresponding_Concurrent_Type is a protected type. 3132 3133-- Is_Protected_Type (synthesized) 3134-- Applies to all entities, true for protected types and subtypes 3135 3136-- Is_Public (Flag10) 3137-- Defined in all entities. Set to indicate that an entity defined in 3138-- one compilation unit can be referenced from other compilation units. 3139-- If this reference causes a reference in the generated code, for 3140-- example in the case of a variable name, then the backend will generate 3141-- an appropriate external name for use by the linker. 3142 3143-- Is_Pure (Flag44) 3144-- Defined in all entities. Set in all entities of a unit to which a 3145-- pragma Pure is applied except for non-intrinsic imported subprograms, 3146-- and also set for the entity of the unit itself. In addition, this 3147-- flag may be set for any other functions or procedures that are known 3148-- to be side effect free, so in the case of subprograms, the Is_Pure 3149-- flag may be used by the optimizer to imply that it can assume freedom 3150-- from side effects (other than those resulting from assignment to Out 3151-- or In Out parameters, or to objects designated by access parameters). 3152 3153-- Is_Pure_Unit_Access_Type (Flag189) 3154-- Defined in access type and subtype entities. Set if the type or 3155-- subtype appears in a pure unit. Used to give an error message at 3156-- freeze time if the access type has a storage pool. 3157 3158-- Is_RACW_Stub_Type (Flag244) 3159-- Defined in all types, true for the stub types generated for remote 3160-- access-to-class-wide types. 3161 3162-- Is_Raised (Flag224) 3163-- Defined in exception entities. Set if the entity is referenced by a 3164-- a raise statement. 3165 3166-- Is_Real_Type (synthesized) 3167-- Applies to all entities, true for real types and subtypes 3168 3169-- Is_Record_Type (synthesized) 3170-- Applies to all entities, true for record types and subtypes, 3171-- includes class-wide types and subtypes (which are also records). 3172 3173-- Is_Remote_Call_Interface (Flag62) 3174-- Defined in all entities. Set in E_Package and E_Generic_Package 3175-- entities to which a pragma Remote_Call_Interface is applied, and 3176-- also on entities declared in the visible part of such a package. 3177 3178-- Is_Remote_Types (Flag61) 3179-- Defined in all entities. Set in E_Package and E_Generic_Package 3180-- entities to which a pragma Remote_Types is applied, and also on 3181-- entities declared in the visible part of the spec of such a package. 3182-- Also set for types which are generic formal types to which the 3183-- pragma Remote_Access_Type applies. 3184 3185-- Is_Renaming_Of_Object (Flag112) 3186-- Defined in all entities, set only for a variable or constant for 3187-- which the Renamed_Object field is non-empty and for which the 3188-- renaming is handled by the front end, by macro substitution of 3189-- a copy of the (evaluated) name tree whereever the variable is used. 3190 3191-- Is_Return_Object (Flag209) 3192-- Defined in all object entities. True if the object is the return 3193-- object of an extended_return_statement; False otherwise. 3194 3195-- Is_Safe_To_Reevaluate (Flag249) 3196-- Defined in all entities. Set in variables that are initialized by 3197-- means of an assignment statement. When initialized their contents 3198-- never change and hence they can be seen by the backend as constants. 3199-- See also Is_True_Constant. 3200 3201-- Is_Scalar_Type (synthesized) 3202-- Applies to all entities, true for scalar types and subtypes 3203 3204-- Is_Shared_Passive (Flag60) 3205-- Defined in all entities. Set in E_Package and E_Generic_Package 3206-- entities to which a pragma Shared_Passive is applied, and also in 3207-- all entities within such packages. 3208 3209-- Is_Standard_Character_Type (synthesized) 3210-- Applies to all entities, true for types and subtypes whose root type 3211-- is one of the standard character types (Character, Wide_Character, or 3212-- Wide_Wide_Character). 3213 3214-- Is_Standard_String_Type (synthesized) 3215-- Applies to all entities, true for types and subtypes whose root 3216-- type is one of the standard string types (String, Wide_String, or 3217-- Wide_Wide_String). 3218 3219-- Is_Static_Type (Flag281) 3220-- Defined in entities. Only set for (sub)types. If set, indicates that 3221-- the type is known to be a static type (defined as a discrete type with 3222-- static bounds, a record all of whose component types are static types, 3223-- or an array, all of whose bounds are of a static type, and also have 3224-- a component type that is a static type). See Set_Uplevel_Type for more 3225-- information on how this flag is used. 3226 3227-- Is_Statically_Allocated (Flag28) 3228-- Defined in all entities. This can only be set for exception, 3229-- variable, constant, and type/subtype entities. If the flag is set, 3230-- then the variable or constant must be allocated statically rather 3231-- than on the local stack frame. For exceptions, the meaning is that 3232-- the exception data should be allocated statically (and indeed this 3233-- flag is always set for exceptions, since exceptions do not have 3234-- local scope). For a type, the meaning is that the type must be 3235-- elaborated at the global level rather than locally. No type marked 3236-- with this flag may depend on a local variable, or on any other type 3237-- which does not also have this flag set to True. For a variable or 3238-- or constant, if the flag is set, then the type of the object must 3239-- either be declared at the library level, or it must also have the 3240-- flag set (since to allocate the object statically, its type must 3241-- also be elaborated globally). 3242 3243-- Is_String_Type (synthesized) 3244-- Applies to all type entities. Determines if the given type is a 3245-- string type, i.e. it is directly a string type or string subtype, 3246-- or a string slice type, or an array type with one dimension and a 3247-- component type that is a character type. 3248 3249-- Is_Subprogram (synthesized) 3250-- Applies to all entities, true for function, procedure and operator 3251-- entities. 3252 3253-- Is_Subprogram_Or_Generic_Subprogram 3254-- Applies to all entities, true for function procedure and operator 3255-- entities, and also for the corresponding generic entities. 3256 3257-- Is_Synchronized_Interface (synthesized) 3258-- Defined in types that are interfaces. True if interface is declared 3259-- synchronized, task, or protected, or is derived from a synchronized 3260-- interface. 3261 3262-- Is_Synchronized_State (synthesized) 3263-- Applies to all entities, true for abstract states that are subject to 3264-- option Synchronous. 3265 3266-- Is_Tag (Flag78) 3267-- Defined in E_Component and E_Constant entities. For regular tagged 3268-- type this flag is set on the tag component (whose name is Name_uTag). 3269-- For CPP_Class tagged types, this flag marks the pointer to the main 3270-- vtable (i.e. the one to be extended by derivation). 3271 3272-- Is_Tagged_Type (Flag55) 3273-- Defined in all entities, set for an entity that is a tagged type 3274 3275-- Is_Task_Interface (synthesized) 3276-- Defined in types that are interfaces. True if interface is declared as 3277-- a task interface, or if it is derived from task interfaces. 3278 3279-- Is_Task_Record_Type (synthesized) 3280-- Applies to all entities, true if Is_Concurrent_Record_Type is true and 3281-- Corresponding_Concurrent_Type is a task type. 3282 3283-- Is_Task_Type (synthesized) 3284-- Applies to all entities. True for task types and subtypes 3285 3286-- Is_Thunk (Flag225) 3287-- Defined in all entities. True for subprograms that are thunks: that is 3288-- small subprograms built by the expander for tagged types that cover 3289-- interface types. As part of the runtime call to an interface, thunks 3290-- displace the pointer to the object (pointer named "this" in the C++ 3291-- terminology) from a secondary dispatch table to the primary dispatch 3292-- table associated with a given tagged type; if the thunk is a function 3293-- that returns an object which covers an interface type then the thunk 3294-- displaces the pointer to the object from the primary dispatch table to 3295-- the secondary dispatch table associated with the interface type. Set 3296-- by Expand_Interface_Thunk and used by Expand_Call to handle extra 3297-- actuals associated with accessibility level. 3298 3299-- Is_Trivial_Subprogram (Flag235) 3300-- Defined in all entities. Set in subprograms where either the body 3301-- consists of a single null statement, or the first or only statement 3302-- of the body raises an exception. This is used for suppressing certain 3303-- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details. 3304 3305-- Is_True_Constant (Flag163) 3306-- Defined in all entities for constants and variables. Set in constants 3307-- and variables which have an initial value specified but which are 3308-- never assigned, partially or in the whole. For variables, it means 3309-- that the variable was initialized but never modified, and hence can be 3310-- treated as a constant by the code generator. For a constant, it means 3311-- that the constant was not modified by generated code (e.g. to set a 3312-- discriminant in an init proc). Assignments by user or generated code 3313-- will reset this flag. See also Is_Safe_To_Reevaluate. 3314 3315-- Is_Type (synthesized) 3316-- Applies to all entities, true for a type entity 3317 3318-- Is_Unchecked_Union (Flag117) [implementation base type only] 3319-- Defined in all entities. Set only in record types to which the 3320-- pragma Unchecked_Union has been validly applied. 3321 3322-- Is_Underlying_Full_View (Flag298) 3323-- Defined in all entities. Set for types which represent the true full 3324-- view of a private type completed by another private type. For further 3325-- details, see attribute Underlying_Full_View. 3326 3327-- Is_Underlying_Record_View (Flag246) [base type only] 3328-- Defined in all entities. Set only in record types that represent the 3329-- underlying record view. This view is built for derivations of types 3330-- with unknown discriminants; it is a record with the same structure 3331-- as its corresponding record type, but whose parent is the full view 3332-- of the parent in the original type extension. 3333 3334-- Is_Unimplemented (Flag284) 3335-- Defined in all entities. Set for any entity to which a valid pragma 3336-- or aspect Unimplemented applies. 3337 3338-- Is_Unsigned_Type (Flag144) 3339-- Defined in all types, but can be set only for discrete and fixed-point 3340-- type and subtype entities. This flag is only valid if the entity is 3341-- frozen. If set it indicates that the representation is known to be 3342-- unsigned (i.e. that no negative values appear in the range). This is 3343-- normally just a reflection of the lower bound of the subtype or base 3344-- type, but there is one case in which the setting is not obvious, 3345-- namely the case of an unsigned subtype of a signed type from which 3346-- a further subtype is obtained using variable bounds. This further 3347-- subtype is still unsigned, but this cannot be determined by looking 3348-- at its bounds or the bounds of the corresponding base type. 3349-- For a subtype indication whose range is statically a null range, 3350-- the flag is set if the lower bound is non-negative, but the flag 3351-- cannot be used to determine the comparison operator to emit in the 3352-- generated code: use the base type. 3353 3354-- Is_Uplevel_Referenced_Entity (Flag283) 3355-- Defined in all entities. Used when unnesting subprograms to indicate 3356-- that an entity is locally defined within a subprogram P, and there is 3357-- a reference to the entity within a subprogram nested within P (at any 3358-- depth). Set for uplevel referenced objects (variables, constants, 3359-- discriminants and loop parameters), and also for upreferenced dynamic 3360-- types, including the cases where the reference is implicit (e.g. the 3361-- type of an array used for computing the location of an element in an 3362-- array. This is used internally in Exp_Unst, see this package for 3363-- further details. 3364 3365-- Is_Valued_Procedure (Flag127) 3366-- Defined in procedure entities. Set if an Import_Valued_Procedure 3367-- or Export_Valued_Procedure pragma applies to the procedure entity. 3368 3369-- Is_Visible_Formal (Flag206) 3370-- Defined in all entities. Set for instances of the formals of a 3371-- formal package. Indicates that the entity must be made visible in the 3372-- body of the instance, to reproduce the visibility of the generic. 3373-- This simplifies visibility settings in instance bodies. 3374 3375-- Is_Visible_Lib_Unit (Flag116) 3376-- Defined in all (root or child) library unit entities. Once compiled, 3377-- library units remain chained to the entities in the parent scope, and 3378-- a separate flag must be used to indicate whether the names are visible 3379-- by selected notation, or not. 3380 3381-- Is_Volatile (Flag16) 3382-- Defined in all type entities, and also in constants, components and 3383-- variables. Set if a pragma Volatile applies to the entity. Also set 3384-- if pragma Shared or pragma Atomic applies to entity. In the case of 3385-- private or incomplete types, this flag is set in both the private 3386-- and full view. The flag is not set reliably on private subtypes, 3387-- and is always retrieved from the base type (but this is not a base- 3388-- type-only attribute because it applies to other entities). Note that 3389-- the backend should use Treat_As_Volatile, rather than Is_Volatile 3390-- to indicate code generation requirements for volatile variables. 3391-- Similarly, any front end test which is concerned with suppressing 3392-- optimizations on volatile objects should test Treat_As_Volatile 3393-- rather than testing this flag. 3394 3395-- Is_Volatile_Full_Access (Flag285) 3396-- Defined in all type entities, and also in constants, components, and 3397-- variables. Set if a pragma Volatile_Full_Access applies to the entity. 3398-- In the case of private and incomplete types, this flag is set in 3399-- both the partial view and the full view. 3400 3401-- Is_Wrapper_Package (synthesized) 3402-- Defined in package entities. Indicates that the package has been 3403-- created as a wrapper for a subprogram instantiation. 3404 3405-- Itype_Printed (Flag202) 3406-- Defined in all type and subtype entities. Set in Itypes if the Itype 3407-- has been printed by Sprint. This is used to avoid printing an Itype 3408-- more than once. 3409 3410-- Kill_Elaboration_Checks (Flag32) 3411-- Defined in all entities. Set by the expander to kill elaboration 3412-- checks which are known not to be needed. Equivalent in effect to 3413-- the use of pragma Suppress (Elaboration_Checks) for that entity 3414-- except that the effect is permanent and cannot be undone by a 3415-- subsequent pragma Unsuppress. 3416 3417-- Kill_Range_Checks (Flag33) 3418-- Defined in all entities. Equivalent in effect to the use of pragma 3419-- Suppress (Range_Checks) for that entity except that the result is 3420-- permanent and cannot be undone by a subsequent pragma Unsuppress. 3421-- This is currently only used in one odd situation in Sem_Ch3 for 3422-- record types, and it would be good to get rid of it??? 3423 3424-- Known_To_Have_Preelab_Init (Flag207) 3425-- Defined in all type and subtype entities. If set, then the type is 3426-- known to have preelaborable initialization. In the case of a partial 3427-- view of a private type, it is only possible for this to be set if a 3428-- pragma Preelaborable_Initialization is given for the type. For other 3429-- types, it is never set if the type does not have preelaborable 3430-- initialization, it may or may not be set if the type does have 3431-- preelaborable initialization. 3432 3433-- Last_Aggregate_Assignment (Node30) 3434-- Applies to controlled constants and variables initialized by an 3435-- aggregate. Points to the last statement associated with the expansion 3436-- of the aggregate. The attribute is used by the finalization machinery 3437-- when marking an object as successfully initialized. 3438 3439-- Last_Assignment (Node26) 3440-- Defined in entities for variables, and OUT or IN OUT formals. Set for 3441-- a local variable or formal to point to the left side of an assignment 3442-- statement assigning a value to the variable. Cleared if the value of 3443-- the entity is referenced. Used to warn about dubious assignment 3444-- statements whose value is not used. 3445 3446-- Last_Entity (Node20) 3447-- Defined in all entities which act as scopes to which a list of 3448-- associated entities is attached (blocks, class subtypes and types, 3449-- entries, functions, loops, packages, procedures, protected objects, 3450-- record types and subtypes, private types, task types and subtypes). 3451-- Points to the last entry in the list of associated entities chained 3452-- through the Next_Entity field. Empty if no entities are chained. 3453 3454-- Last_Formal (synthesized) 3455-- Applies to subprograms and subprogram types, and also in entries 3456-- and entry families. Returns last formal of the subprogram or entry. 3457-- The formals are the first entities declared in a subprogram or in 3458-- a subprogram type (the designated type of an Access_To_Subprogram 3459-- definition) or in an entry. 3460 3461-- Limited_View (Node23) 3462-- Defined in non-generic package entities that are not instances. Bona 3463-- fide package with the limited-view list through the first_entity and 3464-- first_private attributes. The elements of this list are the shadow 3465-- entities created for the types and local packages that are declared 3466-- in a package appearing in a limited_with clause (Ada 2005: AI-50217). 3467 3468-- Linker_Section_Pragma (Node33) 3469-- Present in constant, variable, type and subprogram entities. Points 3470-- to a linker section pragma that applies to the entity, or is Empty if 3471-- no such pragma applies. Note that for constants and variables, this 3472-- field may be set as a result of a linker section pragma applied to the 3473-- type of the object. 3474 3475-- Lit_Indexes (Node18) 3476-- Defined in enumeration types and subtypes. Non-empty only for the 3477-- case of an enumeration root type, where it contains the entity for 3478-- the generated indexes entity. See unit Exp_Imgv for full details of 3479-- the nature and use of this entity for implementing the Image and 3480-- Value attributes for the enumeration type in question. 3481 3482-- Lit_Strings (Node16) 3483-- Defined in enumeration types and subtypes. Non-empty only for the 3484-- case of an enumeration root type, where it contains the entity for 3485-- the literals string entity. See unit Exp_Imgv for full details of 3486-- the nature and use of this entity for implementing the Image and 3487-- Value attributes for the enumeration type in question. 3488 3489-- Low_Bound_Tested (Flag205) 3490-- Defined in all entities. Currently this can only be set for formal 3491-- parameter entries of a standard unconstrained one-dimensional array 3492-- or string type. Indicates that an explicit test of the low bound of 3493-- the formal appeared in the code, e.g. in a pragma Assert. If this 3494-- flag is set, warnings about assuming the index low bound to be one 3495-- are suppressed. 3496 3497-- Machine_Radix_10 (Flag84) 3498-- Defined in decimal types and subtypes, set if the Machine_Radix is 10, 3499-- as the result of the specification of a machine radix representation 3500-- clause. Note that it is possible for this flag to be set without 3501-- having Has_Machine_Radix_Clause True. This happens when a type is 3502-- derived from a type with a clause present. 3503 3504-- Master_Id (Node17) 3505-- Defined in access types and subtypes. Empty unless Has_Task is set for 3506-- the designated type, in which case it points to the entity for the 3507-- Master_Id for the access type master. Also set for access-to-limited- 3508-- class-wide types whose root may be extended with task components, and 3509-- for access-to-limited-interfaces because they can be used to reference 3510-- tasks implementing such interface. 3511 3512-- Materialize_Entity (Flag168) 3513-- Defined in all entities. Set only for renamed obects which should be 3514-- materialized for debugging purposes. This means that a memory location 3515-- containing the renamed address should be allocated. This is needed so 3516-- that the debugger can find the entity. 3517 3518-- May_Inherit_Delayed_Rep_Aspects (Flag262) 3519-- Defined in all entities for types and subtypes. Set if the type is 3520-- derived from a type which has delayed rep aspects (marked by the flag 3521-- Has_Delayed_Rep_Aspects being set). In this case, at the freeze point 3522-- for the derived type we know that the parent type is frozen, and if 3523-- a given attribute has not been set for the derived type, we copy the 3524-- value from the parent type. See Freeze.Inherit_Delayed_Rep_Aspects. 3525 3526-- Mechanism (Uint8) (returned as Mechanism_Type) 3527-- Defined in functions and non-generic formal parameters. Indicates 3528-- the mechanism to be used for the function return or for the formal 3529-- parameter. See full description in the spec of Sem_Mech. This field 3530-- is also set (to the default value of zero = Default_Mechanism) in a 3531-- subprogram body entity but not used in this context. 3532 3533-- Minimum_Accessibility (Node24) 3534-- Defined in formal parameters in the non-generic case. Normally Empty, 3535-- but if expansion is active, and a parameter exists for which a 3536-- dynamic accessibility check is required, then an object is generated 3537-- within such a subprogram representing the accessibility level of the 3538-- subprogram or the formal's Extra_Accessibility - whichever one is 3539-- lesser. The Minimum_Accessibility field then points to this object. 3540 3541-- Modulus (Uint17) [base type only] 3542-- Defined in modular types. Contains the modulus. For the binary case, 3543-- this will be a power of 2, but if Non_Binary_Modulus is set, then it 3544-- will not be a power of 2. 3545 3546-- Must_Be_On_Byte_Boundary (Flag183) 3547-- Defined in entities for types and subtypes. Set if objects of the type 3548-- must always be allocated on a byte boundary (more accurately a storage 3549-- unit boundary). The front end checks that component clauses respect 3550-- this rule, and the backend ensures that record packing does not 3551-- violate this rule. Currently the flag is set only for packed arrays 3552-- longer than 64 bits where the component size is not a power of 2. 3553 3554-- Must_Have_Preelab_Init (Flag208) 3555-- Defined in entities for types and subtypes. Set in the full type of a 3556-- private type or subtype if a pragma Has_Preelaborable_Initialization 3557-- is present for the private type. Used to check that the full type has 3558-- preelaborable initialization at freeze time (this has to be deferred 3559-- to the freeze point because of the rule about overriding Initialize). 3560 3561-- Needs_Activation_Record (Flag306) 3562-- Defined on generated subprogram types. Indicates that a call through 3563-- a named or anonymous access to subprogram requires an activation 3564-- record when compiling with unnesting for C or LLVM. 3565 3566-- Needs_Debug_Info (Flag147) 3567-- Defined in all entities. Set if the entity requires normal debugging 3568-- information to be generated. This is true of all entities that have 3569-- Comes_From_Source set, and also transitively for entities associated 3570-- with such components (e.g. their types). It is true for all entities 3571-- in Debug_Generated_Code mode (-gnatD switch). This is the flag that 3572-- the backend should check to determine whether or not to generate 3573-- debugging information for an entity. Note that callers should always 3574-- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info, 3575-- so that the flag is set properly on subsidiary entities. 3576 3577-- Needs_No_Actuals (Flag22) 3578-- Defined in callable entities (subprograms, entries, access to 3579-- subprograms) which can be called without actuals because all of 3580-- their formals (if any) have default values. This flag simplifies the 3581-- resolution of the syntactic ambiguity involving a call to these 3582-- entities when the return type is an array type, and a call can be 3583-- interpreted as an indexing of the result of the call. It is also 3584-- used to resolve various cases of entry calls. 3585 3586-- Never_Set_In_Source (Flag115) 3587-- Defined in all entities, but can be set only for variables and 3588-- parameters. This flag is set if the object is never assigned a value 3589-- in user source code, either by assignment or by being used as an out 3590-- or in out parameter. Note that this flag is not reset from using an 3591-- initial value, so if you want to test for this case as well, test the 3592-- Has_Initial_Value flag also. 3593-- 3594-- This flag is only for the purposes of issuing warnings, it must not 3595-- be used by the code generator to indicate that the variable is in 3596-- fact a constant, since some assignments in generated code do not 3597-- count (for example, the call to an init proc to assign some but 3598-- not all of the fields in a partially initialized record). The code 3599-- generator should instead use the flag Is_True_Constant. 3600-- 3601-- For the purposes of this warning, the default assignment of access 3602-- variables to null is not considered the assignment of a value (so 3603-- the warning can be given for code that relies on this initial null 3604-- value when no other value is ever set). 3605-- 3606-- In variables and out parameters, if this flag is set after full 3607-- processing of the corresponding declarative unit, it indicates that 3608-- the variable or parameter was never set, and a warning message can 3609-- be issued. 3610-- 3611-- Note: this flag is initially set, and then cleared on encountering 3612-- any construct that might conceivably legitimately set the value. 3613-- Thus during the analysis of a declarative region and its associated 3614-- statement sequence, the meaning of the flag is "not set yet", and 3615-- once this analysis is complete the flag means "never assigned". 3616 3617-- Note: for variables appearing in package declarations, this flag is 3618-- never set. That is because there is no way to tell if some client 3619-- modifies the variable (or, in the case of variables in the private 3620-- part, if some child unit modifies the variables). 3621 3622-- Note: in the case of renamed objects, the flag must be set in the 3623-- ultimate renamed object. Clients noting a possible modification 3624-- should use the Note_Possible_Modification procedure in Sem_Util 3625-- rather than Set_Never_Set_In_Source precisely to deal properly with 3626-- the renaming possibility. 3627 3628-- Next_Component (synthesized) 3629-- Applies to record components. Returns the next component by following 3630-- the chain of declared entities until one is found which corresponds to 3631-- a component (Ekind is E_Component). Any internal types generated from 3632-- the subtype indications of the record components are skipped. Returns 3633-- Empty if no more components. 3634 3635-- Next_Component_Or_Discriminant (synthesized) 3636-- Similar to Next_Component, but includes components and discriminants 3637-- so the input can have either E_Component or E_Discriminant, and the 3638-- same is true for the result. Returns Empty if no more components or 3639-- discriminants in the record. 3640 3641-- Next_Discriminant (synthesized) 3642-- Applies to discriminants returned by First/Next_Discriminant. Returns 3643-- the next language-defined (i.e. perhaps non-girder) discriminant by 3644-- following the chain of declared entities as long as the kind of the 3645-- entity corresponds to a discriminant. Note that the discriminants 3646-- might be the only components of the record. Returns Empty if there 3647-- are no more discriminants. 3648 3649-- Next_Entity (Node2) 3650-- Defined in all entities. The entities of a scope are chained, with 3651-- the head of the list being in the First_Entity field of the scope 3652-- entity. All entities use the Next_Entity field as a forward pointer 3653-- for this list, with Empty indicating the end of the list. Since this 3654-- field is in the base part of the entity, the access routines for this 3655-- field are in Sinfo. 3656 3657-- Next_Formal (synthesized) 3658-- Applies to the entity for a formal parameter. Returns the next formal 3659-- parameter of the subprogram or subprogram type. Returns Empty if there 3660-- are no more formals. 3661 3662-- Next_Formal_With_Extras (synthesized) 3663-- Applies to the entity for a formal parameter. Returns the next 3664-- formal parameter of the subprogram or subprogram type. Returns 3665-- Empty if there are no more formals. The list returned includes 3666-- all the extra formals (see description of Extra_Formal field) 3667 3668-- Next_Index (synthesized) 3669-- Applies to array types and subtypes and to string types and 3670-- subtypes. Yields the next index. The first index is obtained by 3671-- using the First_Index attribute, and then subsequent indexes are 3672-- obtained by applying Next_Index to the previous index. Empty is 3673-- returned to indicate that there are no more indexes. Note that 3674-- unlike most attributes in this package, Next_Index applies to 3675-- nodes for the indexes, not to entities. 3676 3677-- Next_Inlined_Subprogram (Node12) 3678-- Defined in subprograms. Used to chain inlined subprograms used in 3679-- the current compilation, in the order in which they must be compiled 3680-- by the backend to ensure that all inlinings are performed. 3681 3682-- Next_Literal (synthesized) 3683-- Applies to enumeration literals, returns the next literal, or 3684-- Empty if applied to the last literal. This is actually a synonym 3685-- for Next, but its use is preferred in this context. 3686 3687-- No_Dynamic_Predicate_On_Actual (Flag276) 3688-- Defined in discrete types. Set for generic formal types that are used 3689-- in loops and quantified expressions. The corresponing actual cannot 3690-- have dynamic predicates. 3691 3692-- No_Pool_Assigned (Flag131) [root type only] 3693-- Defined in access types. Set if a storage size clause applies to the 3694-- variable with a static expression value of zero. This flag is used to 3695-- generate errors if any attempt is made to allocate or free an instance 3696-- of such an access type. This is set only in the root type, since 3697-- derived types must have the same pool. 3698 3699-- No_Predicate_On_Actual (Flag275) 3700-- Defined in discrete types. Set for generic formal types that are used 3701-- in the spec of a generic package, in constructs that forbid discrete 3702-- types with predicates. 3703 3704-- No_Reordering (Flag239) [implementation base type only] 3705-- Defined in record types. Set only for a base type to which a valid 3706-- pragma No_Component_Reordering applies. 3707 3708-- No_Return (Flag113) 3709-- Defined in all entities. Always false except in the case of procedures 3710-- and generic procedures for which a pragma No_Return is given. 3711 3712-- No_Strict_Aliasing (Flag136) [base type only] 3713-- Defined in access types. Set to direct the backend to avoid any 3714-- optimizations based on an assumption about the aliasing status of 3715-- objects designated by the access type. For the case of the gcc 3716-- backend, the effect is as though all references to objects of 3717-- the type were compiled with -fno-strict-aliasing. This flag is 3718-- set if an unchecked conversion with the access type as a target 3719-- type occurs in the same source unit as the declaration of the 3720-- access type, or if an explicit pragma No_Strict_Aliasing applies. 3721 3722-- No_Tagged_Streams_Pragma (Node32) 3723-- Present in all subtype and type entities. Set for tagged types and 3724-- subtypes (i.e. entities with Is_Tagged_Type set True) if a valid 3725-- pragma/aspect applies to the type. 3726 3727-- Non_Binary_Modulus (Flag58) [base type only] 3728-- Defined in all subtype and type entities. Set for modular integer 3729-- types if the modulus value is other than a power of 2. 3730 3731-- Non_Limited_View (Node19) 3732-- Defined in abstract states and incomplete types that act as shadow 3733-- entities created when analysing a limited with clause (Ada 2005: 3734-- AI-50217). Points to the defining entity of the original declaration. 3735 3736-- Nonzero_Is_True (Flag162) [base type only] 3737-- Defined in enumeration types. Set if any non-zero value is to be 3738-- interpreted as true. Currently this is set for derived Boolean 3739-- types which have a convention of C, C++ or Fortran. 3740 3741-- Normalized_First_Bit (Uint8) 3742-- Defined in components and discriminants. Indicates the normalized 3743-- value of First_Bit for the component, i.e. the offset within the 3744-- lowest addressed storage unit containing part or all of the field. 3745-- Set to No_Uint if no first bit position is assigned yet. 3746 3747-- Normalized_Position (Uint14) 3748-- Defined in components and discriminants. Indicates the normalized 3749-- value of Position for the component, i.e. the offset in storage 3750-- units from the start of the record to the lowest addressed storage 3751-- unit containing part or all of the field. 3752 3753-- Normalized_Position_Max (Uint10) 3754-- Defined in components and discriminants. For almost all cases, this 3755-- is the same as Normalized_Position. The one exception is for the case 3756-- of a discriminated record containing one or more arrays whose length 3757-- depends on discriminants. In this case, the Normalized_Position_Max 3758-- field represents the maximum possible value of Normalized_Position 3759-- assuming min/max values for discriminant subscripts in all fields. 3760-- This is used by Layout in front end layout mode to properly compute 3761-- the maximum size of such records (needed for allocation purposes when 3762-- there are default discriminants, and also for the 'Size value). 3763 3764-- Number_Dimensions (synthesized) 3765-- Applies to array types and subtypes. Returns the number of dimensions 3766-- of the array type or subtype as a value of type Pos. 3767 3768-- Number_Entries (synthesized) 3769-- Applies to concurrent types. Returns the number of entries that are 3770-- declared within the task or protected definition for the type. 3771 3772-- Number_Formals (synthesized) 3773-- Applies to subprograms and subprogram types. Yields the number of 3774-- formals as a value of type Pos. 3775 3776-- Object_Size_Clause (synthesized) 3777-- Applies to entities for types and subtypes. If an object size clause 3778-- is present in the rep item chain for an entity then the attribute 3779-- definition clause node is returned. Otherwise Object_Size_Clause 3780-- returns Empty if no item is present. Usually this is only meaningful 3781-- if the flag Has_Object_Size_Clause is set. This is because when the 3782-- representation item chain is copied for a derived type, it can inherit 3783-- an object size clause that is not applicable to the entity. 3784 3785-- OK_To_Rename (Flag247) 3786-- Defined only in entities for variables. If this flag is set, it 3787-- means that if the entity is used as the initial value of an object 3788-- declaration, the object declaration can be safely converted into a 3789-- renaming to avoid an extra copy. This is set for variables which are 3790-- generated by the expander to hold the result of evaluating some 3791-- expression. Most notably, the local variables used to store the result 3792-- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It 3793-- is only worth setting this flag for composites, since for primitive 3794-- types, it is cheaper to do the copy. 3795 3796-- Optimize_Alignment_Space (Flag241) 3797-- Defined in type, subtype, variable, and constant entities. This 3798-- flag records that the type or object is to be laid out in a manner 3799-- consistent with Optimize_Alignment (Space) mode. The compiler and 3800-- binder ensure a consistent view of any given type or object. If pragma 3801-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3802-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3803 3804-- Optimize_Alignment_Time (Flag242) 3805-- Defined in type, subtype, variable, and constant entities. This 3806-- flag records that the type or object is to be laid out in a manner 3807-- consistent with Optimize_Alignment (Time) mode. The compiler and 3808-- binder ensure a consistent view of any given type or object. If pragma 3809-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3810-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3811 3812-- Original_Access_Type (Node28) 3813-- Defined in E_Access_Subprogram_Type entities. Set only if the access 3814-- type was generated by the expander as part of processing an access- 3815-- to-protected-subprogram type. Points to the access-to-protected- 3816-- subprogram type. 3817 3818-- Original_Array_Type (Node21) 3819-- Defined in modular types and array types and subtypes. Set only if 3820-- the Is_Packed_Array_Impl_Type flag is set, indicating that the type 3821-- is the implementation type for a packed array, and in this case it 3822-- points to the original array type for which this is the packed 3823-- array implementation type. 3824 3825-- Original_Protected_Subprogram (Node41) 3826-- Defined in functions and procedures. Set only on internally built 3827-- dispatching subprograms of protected types to reference their original 3828-- non-dispatching protected subprogram since their names differ. 3829 3830-- Original_Record_Component (Node22) 3831-- Defined in components, including discriminants. The usage depends 3832-- on whether the record is a base type and whether it is tagged. 3833-- 3834-- In base tagged types: 3835-- When the component is inherited in a record extension, it points 3836-- to the original component (the entity of the ancestor component 3837-- which is not itself inherited) otherwise it points to itself. The 3838-- backend uses this attribute to implement the automatic dereference 3839-- in the extension and to apply the transformation: 3840-- 3841-- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp 3842-- 3843-- In base untagged types: 3844-- Always points to itself except for non-girder discriminants, where 3845-- it points to the girder discriminant it renames. 3846-- 3847-- In subtypes (tagged and untagged): 3848-- Points to the component in the base type. 3849 3850-- Overlays_Constant (Flag243) 3851-- Defined in all entities. Set only for E_Constant or E_Variable for 3852-- which there is an address clause that causes the entity to overlay 3853-- a constant object. 3854 3855-- Overridden_Operation (Node26) 3856-- Defined in subprograms. For overriding operations, points to the 3857-- user-defined parent subprogram that is being overridden. Note: this 3858-- attribute uses the same field as Static_Initialization. The latter 3859-- is only defined for internal initialization procedures, for which 3860-- Overridden_Operation is irrelevant. Thus this attribute must not be 3861-- set for init_procs. 3862 3863-- Package_Instantiation (Node26) 3864-- Defined in packages and generic packages. When defined, this field 3865-- references an N_Generic_Instantiation node associated with an 3866-- instantiated package. In the case where the referenced node has 3867-- been rewritten to an N_Package_Specification, the instantiation 3868-- node is available from the Original_Node field of the package spec 3869-- node. This is currently not guaranteed to be set in all cases, but 3870-- when set, the field is used in Get_Unit_Instantiation_Node as 3871-- one of the means of obtaining the instantiation node. Eventually 3872-- it should be set in all cases, including package entities associated 3873-- with formal packages. ??? 3874 3875-- Packed_Array_Impl_Type (Node23) 3876-- Defined in array types and subtypes, except for the string literal 3877-- subtype case, if the corresponding type is packed and implemented 3878-- specially (either bit-packed or packed to eliminate holes in the 3879-- non-contiguous enumeration index types). References the type used to 3880-- represent the packed array, which is either a modular type for short 3881-- static arrays or an array of System.Unsigned in the bit-packed case, 3882-- or a regular array in the non-standard enumeration index case. Note 3883-- that in some situations (internal types and references to fields of 3884-- variant records), it is not always possible to construct this type in 3885-- advance of its use. If this field is empty, then the necessary type 3886-- is declared on the fly for each reference to the array. 3887 3888-- Parameter_Mode (synthesized) 3889-- Applies to formal parameter entities. This is a synonym for Ekind, 3890-- used when obtaining the formal kind of a formal parameter (the result 3891-- is one of E_[In/Out/In_Out]_Parameter). 3892 3893-- Parent_Subtype (Node19) [base type only] 3894-- Defined in E_Record_Type. Set only for derived tagged types, in which 3895-- case it points to the subtype of the parent type. This is the type 3896-- that is used as the Etype of the _parent field. 3897 3898-- Part_Of_Constituents (Elist10) 3899-- Present in abstract state and variable entities. Contains all 3900-- constituents that are subject to indicator Part_Of (both aspect and 3901-- option variants). 3902 3903-- Part_Of_References (Elist11) 3904-- Present in variable entities. Contains all references to the variable 3905-- when it is subject to pragma Part_Of. If the variable is a constituent 3906-- of a single protected/task type, the references are examined as they 3907-- must appear only within the type defintion and the corresponding body. 3908 3909-- Partial_Invariant_Procedure (synthesized) 3910-- Defined in types and subtypes. Set for private types when one or more 3911-- [class-wide] type invariants apply to them. Points to the entity for a 3912-- procedure which checks the invariant. This invariant procedure takes a 3913-- single argument of the given type, and returns if the invariant holds, 3914-- or raises exception Assertion_Error with an appropriate message if it 3915-- does not hold. This attribute is defined but always Empty for private 3916-- subtypes. This attribute is also set for the corresponding full type. 3917-- 3918-- Note: the reason this is marked as a synthesized attribute is that the 3919-- way this is stored is as an element of the Subprograms_For_Type field. 3920 3921-- Partial_Refinement_Constituents (synthesized) 3922-- Defined in abstract state entities. Returns the constituents that 3923-- refine the state in the current scope, which are allowed in a global 3924-- refinement in this scope. These consist of those constituents that are 3925-- abstract states with no or only partial refinement visible, and those 3926-- that are not themselves abstract states. 3927 3928-- Partial_View_Has_Unknown_Discr (Flag280) 3929-- Present in all types. Set to Indicate that the partial view of a type 3930-- has unknown discriminants. A default initialization of an object of 3931-- the type does not require an invariant check (AI12-0133). 3932 3933-- Pending_Access_Types (Elist15) 3934-- Defined in all types. Set for incomplete, private, Taft-amendment 3935-- types, and their corresponding full views. This list contains all 3936-- access types, both named and anonymous, declared between the partial 3937-- and the full view. The list is used by the finalization machinery to 3938-- ensure that the finalization masters of all pending access types are 3939-- fully initialized when the full view is frozen. 3940 3941-- Postconditions_Proc (Node14) 3942-- Defined in functions, procedures, entries, and entry families. Refers 3943-- to the entity of the _Postconditions procedure used to check contract 3944-- assertions on exit from a subprogram. 3945 3946-- Predicate_Function (synthesized) 3947-- Defined in all types. Set for types for which (Has_Predicates is True) 3948-- and for which a predicate procedure has been built that tests that the 3949-- specified predicates are True. Contains the entity for the function 3950-- which takes a single argument of the given type, and returns True if 3951-- the predicate holds and False if it does not. 3952-- 3953-- Note: flag Has_Predicate does not imply that Predicate_Function is set 3954-- to a non-empty entity; this happens, for example, for itypes created 3955-- when instantiating generic units with private types with predicates. 3956-- However, if an explicit pragma Predicate or Predicate aspect is given 3957-- either for private or full type declaration then both Has_Predicates 3958-- and a non-empty Predicate_Function will be set on both the partial and 3959-- full views of the type. 3960-- 3961-- Note: the reason this is marked as a synthesized attribute is that the 3962-- way this is stored is as an element of the Subprograms_For_Type field. 3963 3964-- Predicate_Function_M (synthesized) 3965-- Defined in all types. Present only if Predicate_Function is present, 3966-- and only if the predicate function has Raise_Expression nodes. It 3967-- is the special version created for membership tests, where if one of 3968-- these raise expressions is executed, the result is to return False. 3969 3970-- Predicated_Parent (Node38) 3971-- Defined on itypes created by subtype indications, when the parent 3972-- subtype has predicates. The itype shares the Predicate_Function 3973-- of the predicated parent, but this function may not have been built 3974-- at the point the Itype is constructed, so this attribute allows its 3975-- retrieval at the point a predicate check needs to be generated. 3976-- The utility Predicate_Function takes this link into account. 3977 3978-- Predicates_Ignored (Flag288) 3979-- Defined on all types. Indicates whether the subtype declaration is in 3980-- a context where Assertion_Policy is Ignore, in which case no checks 3981-- (static or dynamic) must be generated for objects of the type. 3982 3983-- Prev_Entity (Node36) 3984-- Defined in all entities. The entities of a scope are chained, and this 3985-- field is used as a backward pointer for this entity list - effectivly 3986-- making the entity chain doubly-linked. 3987 3988-- Primitive_Operations (synthesized) 3989-- Defined in concurrent types, tagged record types and subtypes, tagged 3990-- private types and tagged incomplete types. For concurrent types whose 3991-- Corresponding_Record_Type (CRT) is available, returns the list of 3992-- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist. 3993-- For all the other types returns the Direct_Primitive_Operations. 3994 3995-- Prival (Node17) 3996-- Defined in private components of protected types. Refers to the entity 3997-- of the component renaming declaration generated inside protected 3998-- subprograms, entries or barrier functions. 3999 4000-- Prival_Link (Node20) 4001-- Defined in constants and variables which rename private components of 4002-- protected types. Set to the original private component. 4003 4004-- Private_Dependents (Elist18) 4005-- Defined in private (sub)types. Records the subtypes of the private 4006-- type, derivations from it, and records and arrays with components 4007-- dependent on the type. 4008-- 4009-- The subtypes are traversed when installing and deinstalling (the full 4010-- view of) a private type in order to ensure correct view of the 4011-- subtypes. 4012-- 4013-- Used in similar fashion for incomplete types: holds list of subtypes 4014-- of these incomplete types that have discriminant constraints. The 4015-- full views of these subtypes are constructed when the full view of 4016-- the incomplete type is processed. 4017 4018-- In addition, if the incomplete type is the designated type in an 4019-- access definition for an access parameter, the operation may be 4020-- a dispatching primitive operation, which is only known when the full 4021-- declaration of the type is seen. Subprograms that have such an 4022-- access parameter are also placed in the list of private_dependents. 4023 4024-- Protected_Body_Subprogram (Node11) 4025-- Defined in protected operations. References the entity for the 4026-- subprogram which implements the body of the operation. 4027 4028-- Protected_Formal (Node22) 4029-- Defined in formal parameters (in, in out and out parameters). Used 4030-- only for formals of protected operations. References corresponding 4031-- formal parameter in the unprotected version of the operation that 4032-- is created during expansion. 4033 4034-- Protected_Subprogram (Node39) 4035-- Defined in functions and procedures. Set for the pair of subprograms 4036-- which emulate the runtime semantics of a protected subprogram. Denotes 4037-- the entity of the origial protected subprogram. 4038 4039-- Protection_Object (Node23) 4040-- Applies to protected entries, entry families and subprograms. Denotes 4041-- the entity which is used to rename the _object component of protected 4042-- types. 4043 4044-- Reachable (Flag49) 4045-- Defined in labels. The flag is set over the range of statements in 4046-- which a goto to that label is legal. 4047 4048-- Receiving_Entry (Node19) 4049-- Defined in procedures. Set for an internally generated procedure which 4050-- wraps the original statements of an accept alternative. Designates the 4051-- entity of the task entry being accepted. 4052 4053-- Referenced (Flag156) 4054-- Defined in all entities. Set if the entity is referenced, except for 4055-- the case of an appearance of a simple variable that is not a renaming 4056-- as the left side of an assignment in which case Referenced_As_LHS is 4057-- set instead, or a similar appearance as an out parameter actual, in 4058-- which case Referenced_As_Out_Parameter is set. 4059 4060-- Referenced_As_LHS (Flag36): 4061-- Defined in all entities. This flag is set instead of Referenced if a 4062-- simple variable that is not a renaming appears as the left side of an 4063-- assignment. The reason we distinguish this kind of reference is that 4064-- we have a separate warning for variables that are only assigned and 4065-- never read. 4066 4067-- Referenced_As_Out_Parameter (Flag227): 4068-- Defined in all entities. This flag is set instead of Referenced if a 4069-- simple variable that is not a renaming appears as an actual for an out 4070-- formal. The reason we distinguish this kind of reference is that 4071-- we have a separate warning for variables that are only assigned and 4072-- never read, and out parameters are a special case. 4073 4074-- Refinement_Constituents (Elist8) 4075-- Present in abstract state entities. Contains all the constituents that 4076-- refine the state, in other words, all the hidden states that appear in 4077-- the constituent_list of aspect/pragma Refined_State. 4078 4079-- Register_Exception_Call (Node20) 4080-- Defined in exception entities. When an exception is declared, 4081-- a call is expanded to Register_Exception. This field points to 4082-- the expanded N_Procedure_Call_Statement node for this call. It 4083-- is used for Import/Export_Exception processing to modify the 4084-- register call to make appropriate entries in the special tables 4085-- used for handling these pragmas at run time. 4086 4087-- Related_Array_Object (Node25) 4088-- Defined in array types and subtypes. Used only for the base type 4089-- and subtype created for an anonymous array object. Set to point 4090-- to the entity of the corresponding array object. Currently used 4091-- only for type-related error messages. 4092 4093-- Related_Expression (Node24) 4094-- Defined in variables and types. When Set for internally generated 4095-- entities, it may be used to denote the source expression whose 4096-- elaboration created the variable declaration. If set, it is used 4097-- for generating clearer messages from CodePeer. It is used on source 4098-- entities that are variables in iterator specifications, to provide 4099-- a link to the container that is the domain of iteration. This allows 4100-- for better cross-reference information when the loop modifies elements 4101-- of the container, and suppresses spurious warnings. 4102-- 4103-- Shouldn't it also be used for the same purpose in errout? It seems 4104-- odd to have two mechanisms here??? 4105 4106-- Related_Instance (Node15) 4107-- Defined in the wrapper packages created for subprogram instances. 4108-- The internal subprogram that implements the instance is inside the 4109-- wrapper package, but for debugging purposes its external symbol 4110-- must correspond to the name and scope of the related instance. 4111 4112-- Related_Type (Node27) 4113-- Defined in components, constants and variables. Set when there is an 4114-- associated dispatch table to point to entities containing primary or 4115-- secondary tags. Not set in the _tag component of record types. 4116 4117-- Relative_Deadline_Variable (Node28) [implementation base type only] 4118-- Defined in task type entities. This flag is set if a valid and 4119-- effective pragma Relative_Deadline applies to the base type. Points 4120-- to the entity for a variable that is created to hold the value given 4121-- in a Relative_Deadline pragma for a task type. 4122 4123-- Renamed_Entity (Node18) 4124-- Defined in exception, generic unit, package, and subprogram entities. 4125-- Set when the entity is defined by a renaming declaration. Denotes the 4126-- renamed entity, or transitively the ultimate renamed entity if there 4127-- is a chain of renaming declarations. Empty if no renaming. 4128 4129-- Renamed_In_Spec (Flag231) 4130-- Defined in package entities. If a package renaming occurs within 4131-- a package spec, then this flag is set on the renamed package. The 4132-- purpose is to prevent a warning about unused entities in the renamed 4133-- package. Such a warning would be inappropriate since clients of the 4134-- package can see the entities in the package via the renaming. 4135 4136-- Renamed_Object (Node18) 4137-- Defined in components, constants, discriminants, formal parameters, 4138-- generic formals, loop parameters, and variables. Set to non-Empty if 4139-- the object was declared by a renaming declaration. For constants and 4140-- variables, the attribute references the tree node for the name of the 4141-- renamed object. For formal parameters, the field is used in inlining 4142-- and maps the entities of all formal parameters of a subprogram to the 4143-- entities of the corresponding actuals. For formals of a task entry, 4144-- the attribute denotes the local renaming that replaces the actual 4145-- within an accept statement. For all remaining cases (discriminants, 4146-- loop parameters) the field is Empty. 4147 4148-- Renaming_Map (Uint9) 4149-- Defined in generic subprograms, generic packages, and their 4150-- instances. Also defined in the instances of the corresponding 4151-- bodies. Denotes the renaming map (generic entities => instance 4152-- entities) used to construct the instance by giving an index into 4153-- the tables used to represent these maps. See Sem_Ch12 for further 4154-- details. The maps for package instances are also used when the 4155-- instance is the actual corresponding to a formal package. 4156 4157-- Requires_Overriding (Flag213) 4158-- Defined in all subprograms and entries. Set for subprograms that 4159-- require overriding as defined by RM-2005-3.9.3(6/2). Note that this 4160-- is True only for implicitly declared subprograms; it is not set on the 4161-- parent type's subprogram. See also Is_Abstract_Subprogram. 4162 4163-- Return_Applies_To (Node8) 4164-- Defined in E_Return_Statement. Points to the entity representing 4165-- the construct to which the return statement applies, as defined in 4166-- RM-6.5(4/2). Note that a (simple) return statement within an 4167-- extended_return_statement applies to the extended_return_statement, 4168-- even though it causes the whole function to return. 4169 4170-- Return_Present (Flag54) 4171-- Defined in function and generic function entities. Set if the 4172-- function contains a return statement (used for error checking). 4173-- This flag can also be set in procedure and generic procedure 4174-- entities (for convenience in setting it), but is only tested 4175-- for the function case. 4176 4177-- Returns_By_Ref (Flag90) 4178-- Defined in function entities. Set if the function returns the result 4179-- by reference, either because its return type is a by-reference-type 4180-- or because the function explicitly uses the secondary stack. 4181 4182-- Reverse_Bit_Order (Flag164) [base type only] 4183-- Defined in all record type entities. Set if entity has a Bit_Order 4184-- aspect (set by an aspect clause or attribute definition clause) that 4185-- has reversed the order of bits from the default value. When this flag 4186-- is set, a component clause must specify a set of bits entirely within 4187-- a single storage unit (Ada 95) or within a single machine scalar (see 4188-- Ada 2005 AI-133), or must occupy an integral number of storage units. 4189 4190-- Reverse_Storage_Order (Flag93) [base type only] 4191-- Defined in all record and array type entities. Set if entity has a 4192-- Scalar_Storage_Order aspect (set by an aspect clause or attribute 4193-- definition clause) that has reversed the order of storage elements 4194-- from the default value. When this flag is set for a record type, 4195-- the Bit_Order aspect must be set to the same value (either explicitly 4196-- or as the target default value). 4197 4198-- Rewritten_For_C (Flag287) 4199-- Defined on functions that return a constrained array type, when 4200-- Modify_Tree_For_C is set. Indicates that a procedure with an extra 4201-- out parameter has been created for it, and calls must be rewritten as 4202-- calls to the new procedure. 4203 4204-- RM_Size (Uint13) 4205-- Defined in all type and subtype entities. Contains the value of 4206-- type'Size as defined in the RM. See also the Esize field and 4207-- and the description on "Handling of Type'Size Values". A value 4208-- of zero in this field for a non-discrete type means that 4209-- the front end has not yet determined the size value. For the 4210-- case of a discrete type, this field is always set by the front 4211-- end and zero is a legitimate value for a type with one value. 4212 4213-- Root_Type (synthesized) 4214-- Applies to all type entities. For class-wide types, returns the root 4215-- type of the class covered by the CW type, otherwise returns the 4216-- ultimate derivation ancestor of the given type. This function 4217-- preserves the view, i.e. the Root_Type of a partial view is the 4218-- partial view of the ultimate ancestor, the Root_Type of a full view 4219-- is the full view of the ultimate ancestor. Note that this function 4220-- does not correspond exactly to the use of root type in the RM, since 4221-- in the RM root type applies to a class of types, not to a type. 4222 4223-- Scalar_Range (Node20) 4224-- Defined in all scalar types (including modular types, where the 4225-- bounds are 0 .. modulus - 1). References a node in the tree that 4226-- contains the bounds for the range. Note that this information 4227-- could be obtained by rummaging around the tree, but it is more 4228-- convenient to have it immediately at hand in the entity. The 4229-- contents of Scalar_Range can either be an N_Subtype_Indication 4230-- node (with a constraint), a Range node, or an Integer_Type_Definition, 4231-- but not a simple subtype reference (a subtype is converted into a 4232-- explicit range). 4233 4234-- Scale_Value (Uint16) 4235-- Defined in decimal fixed-point types and subtypes. Contains the scale 4236-- for the type (i.e. the value of type'Scale = the number of decimal 4237-- digits after the decimal point). 4238 4239-- Scope (Node3) 4240-- Defined in all entities. Points to the entity for the scope (block, 4241-- loop, subprogram, package etc.) in which the entity is declared. 4242-- Since this field is in the base part of the entity node, the access 4243-- routines for this field are in Sinfo. Note that for a child unit, 4244-- the Scope will be the parent package, and for a root library unit, 4245-- the Scope will be Standard. 4246 4247-- Scope_Depth (synthesized) 4248-- Applies to program units, blocks, concurrent types and entries, and 4249-- also to record types, i.e. to any entity that can appear on the scope 4250-- stack. Yields the scope depth value, which for those entities other 4251-- than records is simply the scope depth value, for record entities, it 4252-- is the Scope_Depth of the record scope. 4253 4254-- Scope_Depth_Value (Uint22) 4255-- Defined in program units, blocks, concurrent types, and entries. 4256-- Indicates the number of scopes that statically enclose the declaration 4257-- of the unit or type. Library units have a depth of zero. Note that 4258-- record types can act as scopes but do NOT have this field set (see 4259-- Scope_Depth above). 4260 4261-- Scope_Depth_Set (synthesized) 4262-- Applies to a special predicate function that returns a Boolean value 4263-- indicating whether or not the Scope_Depth field has been set. It is 4264-- needed, since returns an invalid value in this case. 4265 4266-- Sec_Stack_Needed_For_Return (Flag167) 4267-- Defined in scope entities (blocks, entries, entry families, functions, 4268-- and procedures). Set to True when secondary stack is used to hold the 4269-- returned value of a function and thus should not be released on scope 4270-- exit. 4271 4272-- Shared_Var_Procs_Instance (Node22) 4273-- Defined in variables. Set non-Empty only if Is_Shared_Passive is 4274-- set, in which case this is the entity for the associated instance of 4275-- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details. 4276 4277-- Size_Check_Code (Node19) 4278-- Defined in constants and variables. Normally Empty. Set if code is 4279-- generated to check the size of the object. This field is used to 4280-- suppress this code if a subsequent address clause is encountered. 4281 4282-- Size_Clause (synthesized) 4283-- Applies to all entities. If a size clause is present in the rep 4284-- item chain for an entity then the attribute definition clause node 4285-- for the size clause is returned. Otherwise Size_Clause returns Empty 4286-- if no item is present. Usually this is only meaningful if the flag 4287-- Has_Size_Clause is set. This is because when the representation item 4288-- chain is copied for a derived type, it can inherit a size clause that 4289-- is not applicable to the entity. 4290 4291-- Size_Depends_On_Discriminant (Flag177) 4292-- Defined in all entities for types and subtypes. Indicates that the 4293-- size of the type depends on the value of one or more discriminants. 4294-- Currently, this flag is only set for arrays which have one or more 4295-- bounds depending on a discriminant value. 4296 4297-- Size_Known_At_Compile_Time (Flag92) 4298-- Defined in all entities for types and subtypes. Indicates that the 4299-- size of objects of the type is known at compile time. This flag is 4300-- used to optimize some generated code sequences, and also to enable 4301-- some error checks (e.g. disallowing component clauses on variable 4302-- length objects). It is set conservatively (i.e. if it is True, the 4303-- size is certainly known at compile time, if it is False, then the 4304-- size may or may not be known at compile time, but the code will 4305-- assume that it is not known). Note that the value may be known only 4306-- to the back end, so the fact that this flag is set does not mean that 4307-- the front end can access the value. 4308 4309-- Small_Value (Ureal21) 4310-- Defined in fixed point types. Points to the universal real for the 4311-- Small of the type, either as given in a representation clause, or 4312-- as computed (as a power of two) by the compiler. 4313 4314-- SPARK_Aux_Pragma (Node41) 4315-- Present in concurrent type, [generic] package spec and package body 4316-- entities. For concurrent types and package specs it refers to the 4317-- SPARK mode setting for the private part. This field points to the 4318-- N_Pragma node that either appears in the private part or is inherited 4319-- from the enclosing context. For package bodies, it refers to the SPARK 4320-- mode of the elaboration sequence after the BEGIN. The fields points to 4321-- the N_Pragma node that either appears in the statement sequence or is 4322-- inherited from the enclosing context. In all cases, if the pragma is 4323-- inherited, then the SPARK_Aux_Pragma_Inherited flag is set. 4324 4325-- SPARK_Aux_Pragma_Inherited (Flag266) 4326-- Present in concurrent type, [generic] package spec and package body 4327-- entities. Set if the SPARK_Aux_Pragma field points to a pragma that is 4328-- inherited, rather than a local one. 4329 4330-- SPARK_Pragma (Node40) 4331-- Present in the following entities: 4332-- 4333-- abstract states 4334-- constants 4335-- entries 4336-- operators 4337-- [generic] packages 4338-- package bodies 4339-- [generic] subprograms 4340-- subprogram bodies 4341-- variables 4342-- types 4343-- 4344-- Points to the N_Pragma node that applies to the initial declaration or 4345-- body. This is either set by a local SPARK_Mode pragma or is inherited 4346-- from the context (from an outer scope for the spec case or from the 4347-- spec for the body case). In the case where the attribute is inherited, 4348-- flag SPARK_Pragma_Inherited is set. Empty if no SPARK_Mode pragma is 4349-- applicable. 4350 4351-- SPARK_Pragma_Inherited (Flag265) 4352-- Present in the following entities: 4353-- 4354-- abstract states 4355-- constants 4356-- entries 4357-- operators 4358-- [generic] packages 4359-- package bodies 4360-- [generic] subprograms 4361-- subprogram bodies 4362-- variables 4363-- types 4364-- 4365-- Set if the SPARK_Pragma attribute points to an inherited pragma rather 4366-- than a local one. 4367 4368-- Spec_Entity (Node19) 4369-- Defined in package body entities. Points to corresponding package 4370-- spec entity. Also defined in subprogram body parameters in the 4371-- case where there is a separate spec, where this field references 4372-- the corresponding parameter entities in the spec. 4373 4374-- SSO_Set_High_By_Default (Flag273) [base type only] 4375-- Defined for record and array types. Set in the base type if a pragma 4376-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4377-- the record or array was declared and therefore applies to it. 4378 4379-- SSO_Set_Low_By_Default (Flag272) [base type only] 4380-- Defined for record and array types. Set in the base type if a pragma 4381-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4382-- the record or array was declared and therefore applies to it. 4383 4384-- Static_Discrete_Predicate (List25) 4385-- Defined in discrete types/subtypes with static predicates (with the 4386-- two flags Has_Predicates and Has_Static_Predicate set). Set if the 4387-- type/subtype has a static predicate. Points to a list of expression 4388-- and N_Range nodes that represent the predicate in canonical form. The 4389-- canonical form has entries sorted in ascending order, with duplicates 4390-- eliminated, and adjacent ranges coalesced, so that there is always a 4391-- gap in the values between successive entries. The entries in this list 4392-- are fully analyzed and typed with the base type of the subtype. Note 4393-- that all entries are static and have values within the subtype range. 4394 4395-- Static_Elaboration_Desired (Flag77) 4396-- Defined in library-level packages. Set by the pragma of the same 4397-- name, to indicate that static initialization must be attempted for 4398-- all types declared in the package, and that a warning must be emitted 4399-- for those types to which static initialization is not available. 4400 4401-- Static_Initialization (Node30) 4402-- Defined in initialization procedures for types whose objects can be 4403-- initialized statically. The value of this attribute is a positional 4404-- aggregate whose components are compile-time static values. Used 4405-- when available in object declarations to eliminate the call to the 4406-- initialization procedure, and to minimize elaboration code. Note: 4407-- This attribute uses the same field as Overridden_Operation, which is 4408-- irrelevant in init_procs. 4409 4410-- Static_Real_Or_String_Predicate (Node25) 4411-- Defined in real types/subtypes with static predicates (with the two 4412-- flags Has_Predicates and Has_Static_Predicate set). Set if the type 4413-- or subtype has a static predicate. Points to the return expression 4414-- of the predicate function. This is the original expression given as 4415-- the predicate except that occurrences of the type are replaced by 4416-- occurrences of the formal parameter of the predicate function (note 4417-- that the spec of this function including this formal parameter name 4418-- is available from the Subprograms_For_Type field; it can be accessed 4419-- as Predicate_Function (typ)). Also, in the case where a predicate is 4420-- inherited, the expression is of the form: 4421-- 4422-- xxxPredicate (typ2 (ent)) AND THEN expression 4423-- 4424-- where typ2 is the type from which the predicate is inherited, ent is 4425-- the entity for the current predicate function, and xxxPredicate is the 4426-- inherited predicate (from typ2). Finally for a predicate that inherits 4427-- from another predicate but does not add a predicate of its own, the 4428-- expression may consist of the above xxxPredicate call on its own. 4429 4430-- Status_Flag_Or_Transient_Decl (Node15) 4431-- Defined in constant, loop, and variable entities. Applies to objects 4432-- that require special treatment by the finalization machinery, such as 4433-- extended return results, IF and CASE expression results, and objects 4434-- inside N_Expression_With_Actions nodes. The attribute contains the 4435-- entity of a flag which specifies particular behavior over a region of 4436-- code or the declaration of a "hook" object. 4437-- In which case is it a flag, or a hook object??? 4438 4439-- Storage_Size_Variable (Node26) [implementation base type only] 4440-- Defined in access types and task type entities. This flag is set 4441-- if a valid and effective pragma Storage_Size applies to the base 4442-- type. Points to the entity for a variable that is created to 4443-- hold the value given in a Storage_Size pragma for an access 4444-- collection or a task type. Note that in the access type case, 4445-- this field is defined only in the root type (since derived types 4446-- share the same storage pool). 4447 4448-- Stored_Constraint (Elist23) 4449-- Defined in entities that can have discriminants (concurrent types 4450-- subtypes, record types and subtypes, private types and subtypes, 4451-- limited private types and subtypes and incomplete types). Points 4452-- to an element list containing the expressions for each of the 4453-- stored discriminants for the record (sub)type. 4454 4455-- Stores_Attribute_Old_Prefix (Flag270) 4456-- Defined in constants. Set when the constant has been generated to save 4457-- the value of attribute 'Old's prefix. 4458 4459-- Strict_Alignment (Flag145) [implementation base type only] 4460-- Defined in all type entities. Indicates that the type is by-reference 4461-- or contains an aliased part. This forbids packing a component of this 4462-- type tighter than the alignment and size of the type, as specified by 4463-- RM 13.2(7) modified by AI12-001 as a Binding Interpretation. 4464 4465-- String_Literal_Length (Uint16) 4466-- Defined in string literal subtypes (which are created to correspond 4467-- to string literals in the program). Contains the length of the string 4468-- literal. 4469 4470-- String_Literal_Low_Bound (Node18) 4471-- Defined in string literal subtypes (which are created to correspond 4472-- to string literals in the program). Contains an expression whose 4473-- value represents the low bound of the literal. This is a copy of 4474-- the low bound of the applicable index constraint if there is one, 4475-- or a copy of the low bound of the index base type if not. 4476 4477-- Subprograms_For_Type (Elist29) 4478-- Defined in all types. The list may contain the entities of the default 4479-- initial condition procedure, invariant procedure, and the two versions 4480-- of the predicate function. 4481-- 4482-- Historical note: This attribute used to be a direct linked list of 4483-- entities rather than an Elist. The Elist allows greater flexibility 4484-- in inheritance of subprograms between views of the same type. 4485 4486-- Subps_Index (Uint24) 4487-- Present in subprogram entries. Set if the subprogram contains nested 4488-- subprograms, or is a subprogram nested within such a subprogram. Holds 4489-- the index in the Exp_Unst.Subps table for the subprogram. Note that 4490-- for the outer level subprogram, this is the starting index in the Subp 4491-- table for the entries for this subprogram. 4492 4493-- Suppress_Elaboration_Warnings (Flag303) 4494-- NOTE: this flag is relevant only for the legacy ABE mechanism and 4495-- should not be used outside of that context. 4496-- 4497-- Defined in all entities, can be set only for subprogram entities and 4498-- for variables. If this flag is set then Sem_Elab will not generate 4499-- elaboration warnings for the subprogram or variable. Suppression of 4500-- such warnings is automatic for subprograms for which elaboration 4501-- checks are suppressed (without the need to set this flag), but the 4502-- flag is also set for various internal entities (such as init procs) 4503-- which are known not to generate any possible access before elaboration 4504-- and it is set on variables when a warning is given to avoid multiple 4505-- elaboration warnings for the same variable. 4506 4507-- Suppress_Initialization (Flag105) 4508-- Defined in all variable, type and subtype entities. If set for a base 4509-- type, then the generation of initialization procedures is suppressed 4510-- for the type. Any other implicit initialization (e.g. from the use of 4511-- pragma Initialize_Scalars) is also suppressed if this flag is set for 4512-- either the subtype in question, or for the base type. For variables, 4513-- this flag suppresses all implicit initialization for the object, even 4514-- if the type would normally require initialization. Set by use of 4515-- pragma Suppress_Initialization and also for internal entities where 4516-- we know that no initialization is required. For example, enumeration 4517-- image table entities set it. 4518 4519-- Suppress_Style_Checks (Flag165) 4520-- Defined in all entities. Suppresses any style checks specifically 4521-- associated with the given entity if set. 4522 4523-- Suppress_Value_Tracking_On_Call (Flag217) 4524-- Defined in all entities. Set in a scope entity if value tracking is to 4525-- be suppressed on any call within the scope. Used when an access to a 4526-- local subprogram is computed, to deal with the possibility that this 4527-- value may be passed around, and if used, may clobber a local variable. 4528 4529-- Task_Body_Procedure (Node25) 4530-- Defined in task types and subtypes. Points to the entity for the task 4531-- task body procedure (as further described in Exp_Ch9, task bodies are 4532-- expanded into procedures). A convenient function to retrieve this 4533-- field is Sem_Util.Get_Task_Body_Procedure. 4534-- 4535-- The last sentence is odd??? Why not have Task_Body_Procedure go to the 4536-- Underlying_Type of the Root_Type??? 4537 4538-- Thunk_Entity (Node31) 4539-- Defined in functions and procedures which have been classified as 4540-- Is_Thunk. Set to the target entity called by the thunk. 4541 4542-- Treat_As_Volatile (Flag41) 4543-- Defined in all type entities, and also in constants, components and 4544-- variables. Set if this entity is to be treated as volatile for code 4545-- generation purposes. Always set if Is_Volatile is set, but can also 4546-- be set as a result of situations (such as address overlays) where 4547-- the front end wishes to force volatile handling to inhibit aliasing 4548-- optimization which might be legally ok, but is undesirable. Note 4549-- that the backend always tests this flag rather than Is_Volatile. 4550-- The front end tests Is_Volatile if it is concerned with legality 4551-- checks associated with declared volatile variables, but if the test 4552-- is for the purposes of suppressing optimizations, then the front 4553-- end should test Treat_As_Volatile rather than Is_Volatile. 4554-- 4555-- Note: before testing Treat_As_Volatile, consider whether it would 4556-- be more appropriate to use Exp_Util.Is_Volatile_Reference instead, 4557-- which catches more cases of volatile references. 4558 4559-- Type_High_Bound (synthesized) 4560-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4561-- the high bound of a scalar type. The returned value is literal for a 4562-- base type, but may be an expression in the case of scalar type with 4563-- dynamic bounds. Note that in the case of a fixed point type, the high 4564-- bound is in units of small, and is an integer. 4565 4566-- Type_Low_Bound (synthesized) 4567-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4568-- the low bound of a scalar type. The returned value is literal for a 4569-- base type, but may be an expression in the case of scalar type with 4570-- dynamic bounds. Note that in the case of a fixed point type, the low 4571-- bound is in units of small, and is an integer. 4572 4573-- Underlying_Full_View (Node19) 4574-- Defined in private subtypes that are the completion of other private 4575-- types, or in private types that are derived from private subtypes. If 4576-- the full view of a private type T is derived from another private type 4577-- with discriminants Td, the full view of T is also private, and there 4578-- is no way to attach to it a further full view that would convey the 4579-- structure of T to the backend. The Underlying_Full_View is an 4580-- attribute of the full view that is a subtype of Td with the same 4581-- constraint as the declaration for T. The declaration for this subtype 4582-- is built at the point of the declaration of T, either as completion, 4583-- or as a subtype declaration where the base type is private and has a 4584-- private completion. If Td is already constrained, then its full view 4585-- can serve directly as the full view of T. 4586 4587-- Underlying_Record_View (Node28) 4588-- Defined in record types. Set for record types that are extensions of 4589-- types with unknown discriminants, and also set for internally built 4590-- underlying record views to reference its original record type. Record 4591-- types that are extensions of types with unknown discriminants do not 4592-- have a completion, but they cannot be used without having some 4593-- discriminated view at hand. This view is a record type with the same 4594-- structure, whose parent type is the full view of the parent in the 4595-- original type extension. 4596 4597-- Underlying_Type (synthesized) 4598-- Applies to all entities. This is the identity function except in the 4599-- case where it is applied to an incomplete or private type, in which 4600-- case it is the underlying type of the type declared by the completion, 4601-- or Empty if the completion has not yet been encountered and analyzed. 4602-- 4603-- Note: the reason this attribute applies to all entities, and not just 4604-- types, is to legitimize code where Underlying_Type is applied to an 4605-- entity which may or may not be a type, with the intent that if it is a 4606-- type, its underlying type is taken. 4607-- 4608-- Note also that the value of this attribute is interesting only after 4609-- the full view of the parent type has been processed. If the parent 4610-- type is declared in an enclosing package, the attribute will be non- 4611-- trivial only after the full view of the type has been analyzed. 4612 4613-- Universal_Aliasing (Flag216) [implementation base type only] 4614-- Defined in all type entities. Set to direct the back-end to avoid 4615-- any optimizations based on type-based alias analysis for this type. 4616-- Indicates that objects of this type can alias objects of any other 4617-- types, which guarantees that any objects can be referenced through 4618-- access types designating this type safely, whatever the actual type 4619-- of these objects. In other words, the effect is as though access 4620-- types designating this type were subject to No_Strict_Aliasing. 4621 4622-- Unset_Reference (Node16) 4623-- Defined in variables and out parameters. This is normally Empty. It 4624-- is set to point to an identifier that represents a reference to the 4625-- entity before any value has been set. Only the first such reference 4626-- is identified. This field is used to generate a warning message if 4627-- necessary (see Sem_Warn.Check_Unset_Reference). 4628 4629-- Used_As_Generic_Actual (Flag222) 4630-- Defined in all entities, set if the entity is used as an argument to 4631-- a generic instantiation. Used to tune certain warning messages, and 4632-- in checking type conformance within an instantiation that involves 4633-- incomplete formal and actual types. 4634 4635-- Uses_Lock_Free (Flag188) 4636-- Defined in protected type entities. Set to True when the Lock Free 4637-- implementation is used for the protected type. This implementation is 4638-- based on atomic transactions and doesn't require anymore the use of 4639-- Protection object (see System.Tasking.Protected_Objects). 4640 4641-- Uses_Sec_Stack (Flag95) 4642-- Defined in scope entities (blocks, entries, entry families, functions, 4643-- loops, and procedures). Set to True when the secondary stack is used 4644-- in this scope and must be released on exit unless flag 4645-- Sec_Stack_Needed_For_Return is set. 4646 4647-- Validated_Object (Node38) 4648-- Defined in variables. Contains the object whose value is captured by 4649-- the variable for validity check purposes. 4650 4651-- Warnings_Off (Flag96) 4652-- Defined in all entities. Set if a pragma Warnings (Off, entity-name) 4653-- is used to suppress warnings for a given entity. It is also used by 4654-- the compiler in some situations to kill spurious warnings. Note that 4655-- clients should generally not test this flag directly, but instead 4656-- use function Has_Warnings_Off. 4657 4658-- Warnings_Off_Used (Flag236) 4659-- Defined in all entities. Can only be set if Warnings_Off is set. If 4660-- set indicates that a warning was suppressed by the Warnings_Off flag, 4661-- and Unmodified/Unreferenced would not have suppressed the warning. 4662 4663-- Warnings_Off_Used_Unmodified (Flag237) 4664-- Defined in all entities. Can only be set if Warnings_Off is set and 4665-- Has_Pragma_Unmodified is not set. If set indicates that a warning was 4666-- suppressed by the Warnings_Off status but that pragma Unmodified 4667-- would also have suppressed the warning. 4668 4669-- Warnings_Off_Used_Unreferenced (Flag238) 4670-- Defined in all entities. Can only be set if Warnings_Off is set and 4671-- Has_Pragma_Unreferenced is not set. If set indicates that a warning 4672-- was suppressed by the Warnings_Off status but that pragma Unreferenced 4673-- would also have suppressed the warning. 4674 4675-- Was_Hidden (Flag196) 4676-- Defined in all entities. Used to save the value of the Is_Hidden 4677-- attribute when the limited-view is installed (Ada 2005: AI-217). 4678 4679-- Wrapped_Entity (Node27) 4680-- Defined in functions and procedures which have been classified as 4681-- Is_Primitive_Wrapper. Set to the entity being wrapper. 4682 4683--------------------------- 4684-- Renaming and Aliasing -- 4685--------------------------- 4686 4687-- Several entity attributes relate to renaming constructs, and to the use of 4688-- different names to refer to the same entity. The following is a summary of 4689-- these constructs and their prefered uses. 4690 4691-- There are three related attributes: 4692 4693-- Renamed_Entity 4694-- Renamed_Object 4695-- Alias 4696 4697-- They all overlap because they are supposed to apply to different entity 4698-- kinds. They are semantically related, and have the following intended uses: 4699 4700-- a) Renamed_Entity applies to entities in renaming declarations that rename 4701-- an entity, so the value of the attribute IS an entity. This applies to 4702-- generic renamings, package renamings, exception renamings, and subprograms 4703-- renamings that rename a subprogram (rather than an attribute, an entry, a 4704-- protected operation, etc). 4705 4706-- b) Alias applies to overloadable entities, and the value is an overloadable 4707-- entity. So this is a subset of the previous one. We use the term Alias to 4708-- cover both renamings and inherited operations, because both cases are 4709-- handled in the same way when expanding a call. Namely the Alias of a given 4710-- subprogram is the subprogram that will actually be called. 4711 4712-- Both a) and b) are set transitively, so that in fact it is not necessary to 4713-- traverse chains of renamings when looking for the original entity: it's 4714-- there in one step (this is done when analyzing renaming declarations other 4715-- than object renamings in sem_ch8). 4716 4717-- c) Renamed_Object applies to constants and variables. Given that the name 4718-- in an object renaming declaration is not necessarily an entity name, the 4719-- value of the attribute is the tree for that name, eg AR (1).Comp. The case 4720-- when that name is in fact an entity is not handled specially. This is why 4721-- in a few cases we need to use a loop to trace a chain of object renamings 4722-- where all of them happen to be entities. So: 4723 4724-- X : integer; 4725-- Y : integer renames X; -- renamed object is the identifier X 4726-- Z : integer renames Y; -- renamed object is the identifier Y 4727 4728-- The front-end does not store explicitly the fact that Z renames X. 4729 4730-------------------------------------- 4731-- Delayed Freezing and Elaboration -- 4732-------------------------------------- 4733 4734-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 4735-- freeze node, which appears later in the expanded tree. 4736 4737-- a) The flag is used by the front-end to trigger expansion actions 4738-- which include the generation of that freeze node. Typically this happens at 4739-- the end of the current compilation unit, or before the first subprogram 4740-- body is encountered in the current unit. See files freeze and exp_ch13 for 4741-- details on the actions triggered by a freeze node, which include the 4742-- construction of initialization procedures and dispatch tables. 4743 4744-- b) The flag is used by the backend to defer elaboration of the entity until 4745-- its freeze node is seen. In the absence of an explicit freeze node, an 4746-- entity is frozen (and elaborated) at the point of declaration. 4747 4748-- For object declarations, the flag is set when an address clause for the 4749-- object is encountered. Legality checks on the address expression only 4750-- take place at the freeze point of the object. 4751 4752-- Most types have an explicit freeze node, because they cannot be elaborated 4753-- until all representation and operational items that apply to them have been 4754-- analyzed. Private types and incomplete types have the flag set as well, as 4755-- do task and protected types. 4756 4757-- Implicit base types created for type derivations, as well as classwide 4758-- types created for all tagged types, have the flag set. 4759 4760-- If a subprogram has an access parameter whose designated type is incomplete 4761-- the subprogram has the flag set. 4762 4763------------------ 4764-- Access Kinds -- 4765------------------ 4766 4767-- The following entity kinds are introduced by the corresponding type 4768-- definitions: 4769 4770-- E_Access_Type, 4771-- E_General_Access_Type, 4772-- E_Access_Subprogram_Type, 4773-- E_Anonymous_Access_Subprogram_Type, 4774-- E_Access_Protected_Subprogram_Type, 4775-- E_Anonymous_Access_Protected_Subprogram_Type 4776-- E_Anonymous_Access_Type. 4777 4778-- E_Access_Subtype is for an access subtype created by a subtype 4779-- declaration. 4780 4781-- In addition, we define the kind E_Allocator_Type to label allocators. 4782-- This is because special resolution rules apply to this construct. 4783-- Eventually the constructs are labeled with the access type imposed by 4784-- the context. The backend should never see types with this Ekind. 4785 4786-- Similarly, the type E_Access_Attribute_Type is used as the initial kind 4787-- associated with an access attribute. After resolution a specific access 4788-- type will be established as determined by the context. 4789 4790-- Finally, the type Any_Access is used to label -null- during type 4791-- resolution. Any_Access is also replaced by the context type after 4792-- resolution. 4793 4794-------------------------------- 4795-- Classification of Entities -- 4796-------------------------------- 4797 4798-- The classification of program entities which follows is a refinement of 4799-- the list given in RM 3.1(1). E.g., separate entities denote subtypes of 4800-- different type classes. Ada 95 entities include class wide types, 4801-- protected types, subprogram types, generalized access types, generic 4802-- formal derived types and generic formal packages. 4803 4804-- The order chosen for these kinds allows us to classify related entities 4805-- so that they are contiguous.

Meanwhile, the access 6833 -- procedures in the body of Einfo permit many, but not all, attributes 6834 -- to be applied to an E_Void entity, precisely so that this kind of 6835 -- pre-setting of attributes works. This is really a hole in the dynamic 6836 -- type checking, since there is no assurance that the eventual Ekind 6837 -- value will be appropriate for the attributes set, and the consequence 6838 -- is that the dynamic type checking in the Einfo body is unnecessarily 6839 -- weak.

For full 6848 -- details of the meaning of these alignment types, see description 6849 -- of the Component_Alignment pragma. 6850 6851 type Component_Alignment_Kind is ( 6852 Calign_Default, -- default alignment 6853 Calign_Component_Size, -- natural alignment for component size 6854 Calign_Component_Size_4, -- natural for size <= 4, 4 for size >= 4 6855 Calign_Storage_Unit); -- all components byte aligned 6856 6857 ----------------------------------- 6858 -- Floating Point Representation -- 6859 ----------------------------------- 6860 6861 type Float_Rep_Kind is ( 6862 IEEE_Binary, -- IEEE 754p conforming binary format 6863 AAMP); -- AAMP format 6864 6865 --------------- 6866 -- Iterators -- 6867 --------------- 6868 6869 -- In addition to attributes that are stored as plain data, other 6870 -- attributes are procedural, and require some small amount of 6871 -- computation. Of course, from the point of view of a user of this 6872 -- package, the distinction is not visible (even the field information 6873 -- provided below should be disregarded, as it is subject to change 6874 -- without notice). A number of attributes appear as lists: lists of 6875 -- formals, lists of actuals, of discriminants, etc. For these, pairs 6876 -- of functions are defined, which take the form: 6877 6878 -- function First_Thing (E : Enclosing_Construct) return Thing; 6879 -- function Next_Thing (T : Thing) return Thing; 6880 6881 -- The end of iteration is always signaled by a value of Empty, so that 6882 -- loops over these chains invariably have the form: 6883 6884 -- This : Thing; 6885 -- ... 6886 -- This := First_Thing (E); 6887 6888 -- while Present (This) loop 6889 -- Do_Something_With (This); 6890 -- ... 6891 -- This := Next_Thing (This); 6892 -- end loop; 6893 6894 ----------------------------------- 6895 -- Handling of Check Suppression -- 6896 ----------------------------------- 6897 6898 -- There are three ways that checks can be suppressed: 6899 6900 -- 1. At the command line level 6901 -- 2. At the scope level. 6902 -- 3. At the entity level. 6903 6904 -- See spec of Sem in sem.ads for details of the data structures used 6905 -- to keep track of these various methods for suppressing checks. 6906 6907 ------------------------------- 6908 -- Handling of Discriminants -- 6909 ------------------------------- 6910 6911 -- During semantic processing, discriminants are separate entities which 6912 -- reflect the semantic properties and allowed usage of discriminants in 6913 -- the language. 6914 6915 -- In the case of discriminants used as bounds, the references are handled 6916 -- directly, since special processing is needed in any case. However, there 6917 -- are two circumstances in which discriminants are referenced in a quite 6918 -- general manner, like any other variables: 6919 6920 -- In initialization expressions for records. Note that the expressions 6921 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline 6922 -- pragmas are effectively in this category, since these pragmas are 6923 -- converted to initialized record fields in the Corresponding_Record_ 6924 -- Type. 6925 6926 -- In task and protected bodies, where the discriminant values may be 6927 -- referenced freely within these bodies. Discriminants can also appear 6928 -- in bounds of entry families and in defaults of operations. 6929 6930 -- In both these cases, the discriminants must be treated essentially as 6931 -- objects. The following approach is used to simplify and minimize the 6932 -- special processing that is required. 6933 6934 -- When a record type with discriminants is analyzed, semantic processing 6935 -- creates the entities for the discriminants. It also creates additional 6936 -- sets of entities called discriminals, one for each of the discriminants, 6937 -- and the Discriminal field of the discriminant entity points to this 6938 -- additional entity, which is initially created as an uninitialized 6939 -- (E_Void) entity. 6940 6941 -- During expansion of expressions, any discriminant reference is replaced 6942 -- by a reference to the corresponding discriminal. When the initialization 6943 -- procedure for the record is created (there will always be one, since 6944 -- discriminants are present, see Exp_Ch3 for further details), the 6945 -- discriminals are used as the entities for the formal parameters of 6946 -- this initialization procedure. The references to these discriminants 6947 -- have already been replaced by references to these discriminals, which 6948 -- are now the formal parameters corresponding to the required objects. 6949 6950 -- In the case of a task or protected body, the semantics similarly creates 6951 -- a set of discriminals for the discriminants of the task or protected 6952 -- type. When the procedure is created for the task body, the parameter 6953 -- passed in is a reference to the task value type, which contains the 6954 -- required discriminant values. The expander creates a set of declarations 6955 -- of the form: 6956 6957 -- discr_nameD : constant discr_type renames _task.discr_name; 6958 6959 -- where discr_nameD is the discriminal entity referenced by the task 6960 -- discriminant, and _task is the task value passed in as the parameter. 6961 -- Again, any references to discriminants in the task body have been 6962 -- replaced by the discriminal reference, which is now an object that 6963 -- contains the required value. 6964 6965 -- This approach for tasks means that two sets of discriminals are needed 6966 -- for a task type, one for the initialization procedure, and one for the 6967 -- task body. This works out nicely, since the semantics allocates one set 6968 -- for the task itself, and one set for the corresponding record. 6969 6970 -- The one bit of trickiness arises in making sure that the right set of 6971 -- discriminals is used at the right time. First the task definition is 6972 -- processed. Any references to discriminants here are replaced by the 6973 -- corresponding *task* discriminals (the record type doesn't even exist 6974 -- yet, since it is constructed as part of the expansion of the task 6975 -- declaration, which happens after the semantic processing of the task 6976 -- definition). The discriminants to be used for the corresponding record 6977 -- are created at the same time as the other discriminals, and held in the 6978 -- CR_Discriminant field of the discriminant. A use of the discriminant in 6979 -- a bound for an entry family is replaced with the CR_Discriminant because 6980 -- it controls the bound of the entry queue array which is a component of 6981 -- the corresponding record. 6982 6983 -- Just before the record initialization routine is constructed, the 6984 -- expander exchanges the task and record discriminals. This has two 6985 -- effects. First the generation of the record initialization routine 6986 -- uses the discriminals that are now on the record, which is the set 6987 -- that used to be on the task, which is what we want. 6988 6989 -- Second, a new set of (so far unused) discriminals is now on the task 6990 -- discriminants, and it is this set that will be used for expanding the 6991 -- task body, and also for the discriminal declarations at the start of 6992 -- the task body. 6993 6994 --------------------------------------------------- 6995 -- Handling of private data in protected objects -- 6996 --------------------------------------------------- 6997 6998 -- Private components in protected types pose problems similar to those 6999 -- of discriminants. Private data is visible and can be directly referenced 7000 -- from protected bodies. However, when protected entries and subprograms 7001 -- are expanded into corresponding bodies and barrier functions, private 7002 -- components lose their original context and visibility. 7003 7004 -- To remedy this side effect of expansion, private components are expanded 7005 -- into renamings called "privals", by analogy with "discriminals". 7006 7007 -- private_comp : comp_type renames _object.private_comp; 7008 7009 -- Prival declarations are inserted during the analysis of subprogram and 7010 -- entry bodies to ensure proper visibility for any subsequent expansion. 7011 -- _Object is the formal parameter of the generated corresponding body or 7012 -- a local renaming which denotes the protected object obtained from entry 7013 -- parameter _O. Privals receive minimal decoration upon creation and are 7014 -- categorized as either E_Variable for the general case or E_Constant when 7015 -- they appear in functions. 7016 7017 -- Along with the local declarations, each private component carries a 7018 -- placeholder which references the prival entity in the current body. This 7019 -- form of indirection is used to resolve name clashes of privals and other 7020 -- locally visible entities such as parameters, local objects, entry family 7021 -- indexes or identifiers used in the barrier condition. 7022 7023 -- When analyzing the statements of a protected subprogram or entry, any 7024 -- reference to a private component must resolve to the locally declared 7025 -- prival through normal visibility. In case of name conflicts (the cases 7026 -- above), the prival is marked as hidden and acts as a weakly declared 7027 -- entity. As a result, the reference points to the correct entity. When a 7028 -- private component is denoted by an expanded name (prot_type.comp for 7029 -- example), the expansion mechanism uses the placeholder of the component 7030 -- to correct the Entity and Etype of the reference. 7031 7032 ------------------- 7033 -- Type Synonyms -- 7034 ------------------- 7035 7036 -- The following type synonyms are used to tidy up the function and 7037 -- procedure declarations that follow, and also to make it possible to meet 7038 -- the requirement for the XEINFO utility that all function specs must fit 7039 -- on a single source line. 7040 7041 subtype B is Boolean; 7042 subtype C is Component_Alignment_Kind; 7043 subtype E is Entity_Id; 7044 subtype F is Float_Rep_Kind; 7045 subtype M is Mechanism_Type; 7046 subtype N is Node_Id; 7047 subtype U is Uint; 7048 subtype R is Ureal; 7049 subtype L is Elist_Id; 7050 subtype S is List_Id; 7051 7052 -------------------------------- 7053 -- Attribute Access Functions -- 7054 -------------------------------- 7055 7056 -- All attributes are manipulated through a procedural interface.
