Other 48-- attributes include sets of meanings for overloaded names, possible 49-- types for overloaded expressions, flags to indicate deferred constants, 50-- incomplete types, etc. These attributes are stored in available fields in 51-- tree nodes (i.e. fields not used by the parser, as defined by the Sinfo 52-- package specification), and accessed by means of a set of subprograms 53-- which define an abstract interface. 54 55-- There are two kinds of semantic information 56 57-- First, the tree nodes with the following Nkind values: 58 59-- N_Defining_Identifier 60-- N_Defining_Character_Literal 61-- N_Defining_Operator_Symbol 62 63-- are called Entities, and constitute the information that would often 64-- be stored separately in a symbol table. These nodes are all extended 65-- to provide extra space, and contain fields which depend on the entity 66-- kind, as defined by the contents of the Ekind field. The use of the 67-- Ekind field, and the associated fields in the entity, are defined 68-- in this package, as are the access functions to these fields. 69 70-- Second, in some cases semantic information is stored directly in other 71-- kinds of nodes, e.g. the Etype field, used to indicate the type of an 72-- expression. The access functions to these fields are defined in the 73-- Sinfo package, but their full documentation is to be found in 74-- the Einfo package specification. 75 76-- Declaration processing places information in the nodes of their defining 77-- identifiers. Name resolution places in all other occurrences of an 78-- identifier a pointer to the corresponding defining occurrence. 79 80-------------------------------- 81-- The XEINFO Utility Program -- 82-------------------------------- 83 84-- XEINFO is a utility program which automatically produces a C header file, 85-- einfo.h from the spec and body of package Einfo. It reads the input files 86-- einfo.ads and einfo.adb and produces the output file einfo.h. XEINFO is run 87-- automatically by the build scripts when you do a full bootstrap. 88 89-- In order for this utility program to operate correctly, the form of the 90-- einfo.ads and einfo.adb files must meet certain requirements and be laid 91-- out in a specific manner. 92 93-- The general form of einfo.ads is as follows: 94 95-- type declaration for type Entity_Kind 96-- subtype declarations declaring subranges of Entity_Kind 97-- subtype declarations declaring synonyms for some standard types 98-- function specs for attributes 99-- procedure specs 100-- pragma Inline declarations 101 102-- This order must be observed. There are no restrictions on the procedures, 103-- since the C header file only includes functions (The back end is not 104-- allowed to modify the generated tree). However, functions are required to 105-- have headers that fit on a single line. 106 107-- XEINFO reads and processes the function specs and the pragma Inlines. For 108-- functions that are declared as inlined, XEINFO reads the corresponding body 109-- from einfo.adb, and processes it into C code. This results in some strict 110-- restrictions on which functions can be inlined: 111 112-- The function spec must be on a single line 113 114-- There can only be a single statement, contained on a single line, 115-- not counting any pragma Assert statements. 116 117-- This single statement must either be a function call with simple, 118-- single token arguments, or it must be a membership test of the form 119-- a in b, where a and b are single tokens. 120 121-- For functions that are not inlined, there is no restriction on the body, 122-- and XEINFO generates a direct reference in the C header file which allows 123-- the C code in the backend to directly call the corresponding Ada body. 124 125---------------------------------- 126-- Handling of Type'Size Values -- 127---------------------------------- 128 129-- The Ada 95 RM contains some rather peculiar (to us) rules on the value 130-- of type'Size (see RM 13.3(55)). We have found that attempting to use 131-- these RM Size values generally, and in particular for determining the 132-- default size of objects, creates chaos, and major incompatibilities in 133-- existing code. 134 135-- We proceed as follows, for discrete and fixed-point subtypes, we have 136-- two separate sizes for each subtype: 137 138-- The Object_Size, which is used for determining the default size of 139-- objects and components. This size value can be referred to using the 140-- Object_Size attribute. The phrase "is used" here means that it is 141-- the basis of the determination of the size. The backend is free to 142-- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone 143-- character might be stored in 32 bits on a machine with no efficient 144-- byte access instructions such as the Alpha. 145 146-- The default rules for the value of Object_Size for fixed-point and 147-- discrete types are as follows: 148 149-- The Object_Size for base subtypes reflect the natural hardware 150-- size in bits (see Ttypes and Cstand for integer types). For 151-- enumeration and fixed-point base subtypes have 8, 16, 32, or 64 152-- bits for this size, depending on the range of values to be stored. 153 154-- The Object_Size of a subtype is the same as the Object_Size of 155-- the subtype from which it is obtained. 156 157-- The Object_Size of a derived base type is copied from the parent 158-- base type, and the Object_Size of a derived first subtype is copied 159-- from the parent first subtype. 160 161-- The Value_Size which is the number of bits required to store a value 162-- of the type. This size can be referred to using the Value_Size 163-- attribute. This value is used to determine how tightly to pack 164-- records or arrays with components of this type, and also affects 165-- the semantics of unchecked conversion (unchecked conversions where 166-- the Value_Size values differ generate a warning, and are potentially 167-- target dependent). 168 169-- The default rules for the value of Value_Size are as follows: 170 171-- The Value_Size for a base subtype is the minimum number of bits 172-- required to store all values of the type (including the sign bit 173-- only if negative values are possible). 174 175-- If a subtype statically matches the first subtype, then it has 176-- by default the same Value_Size as the first subtype. This is a 177-- consequence of RM 13.1(14) ("if two subtypes statically match, 178-- then their subtype-specific aspects are the same".) 179 180-- All other subtypes have a Value_Size corresponding to the minimum 181-- number of bits required to store all values of the subtype. For 182-- dynamic bounds, it is assumed that the value can range down or up 183-- to the corresponding bound of the ancestor. 184 185-- The RM defined attribute Size corresponds to the Value_Size attribute. 186 187-- The Size attribute may be defined for a first-named subtype. This sets 188-- the Value_Size of the first-named subtype to the given value, and the 189-- Object_Size of this first-named subtype to the given value padded up 190-- to an appropriate boundary. It is a consequence of the default rules 191-- above that this Object_Size will apply to all further subtypes. On the 192-- other hand, Value_Size is affected only for the first subtype, any 193-- dynamic subtypes obtained from it directly, and any statically matching 194-- subtypes. The Value_Size of any other static subtypes is not affected. 195 196-- Value_Size and Object_Size may be explicitly set for any subtype using 197-- an attribute definition clause. Note that the use of these attributes 198-- can cause the RM 13.1(14) rule to be violated. If two access types 199-- reference aliased objects whose subtypes have differing Object_Size 200-- values as a result of explicit attribute definition clauses, then it 201-- is erroneous to convert from one access subtype to the other. 202 203-- At the implementation level, Esize stores the Object_Size and the 204-- RM_Size field stores the Value_Size (and hence the value of the 205-- Size attribute, which, as noted above, is equivalent to Value_Size). 206 207-- To get a feel for the difference, consider the following examples (note 208-- that in each case the base is short_short_integer with a size of 8): 209 210-- Object_Size Value_Size 211 212-- type x1 is range 0..5; 8 3 213 214-- type x2 is range 0..5; 215-- for x2'size use 12; 16 12 216 217-- subtype x3 is x2 range 0 .. 3; 16 2 218 219-- subtype x4 is x2'base range 0 .. 10; 8 4 220 221-- dynamic : x2'Base range -64 .. +63; 222 223-- subtype x5 is x2 range 0 .. dynamic; 16 3* 224 225-- subtype x6 is x2'base range 0 .. dynamic; 8 7* 226 227-- Note: the entries marked * are not actually specified by the Ada 95 RM, 228-- but it seems in the spirit of the RM rules to allocate the minimum number 229-- of bits known to be large enough to hold the given range of values. 230 231-- So far, so good, but GNAT has to obey the RM rules, so the question is 232-- under what conditions must the RM Size be used. The following is a list 233-- of the occasions on which the RM Size must be used: 234 235-- Component size for packed arrays or records 236-- Value of the attribute Size for a type 237-- Warning about sizes not matching for unchecked conversion 238 239-- The RM_Size field keeps track of the RM Size as needed in these 240-- three situations. 241 242-- For elementary types other than discrete and fixed-point types, the 243-- Object_Size and Value_Size are the same (and equivalent to the RM 244-- attribute Size). Only Size may be specified for such types. 245 246-- For composite types, Object_Size and Value_Size are computed from their 247-- respective value for the type of each element as well as the layout. 248 249-- All size attributes are stored as Uint values. Negative values are used to 250-- reference GCC expressions for the case of non-static sizes, as explained 251-- in Repinfo. 252 253-------------------------------------- 254-- Delayed Freezing and Elaboration -- 255-------------------------------------- 256 257-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 258-- freeze node, which appears later in the expanded tree. 259 260-- a) The flag is used by the front-end to trigger expansion actions which 261-- include the generation of that freeze node. Typically this happens at the 262-- end of the current compilation unit, or before the first subprogram body is 263-- encountered in the current unit. See files freeze and exp_ch13 for details 264-- on the actions triggered by a freeze node, which include the construction 265-- of initialization procedures and dispatch tables. 266 267-- b) The presence of a freeze node on an entity is used by the backend to 268-- defer elaboration of the entity until its freeze node is seen. In the 269-- absence of an explicit freeze node, an entity is frozen (and elaborated) 270-- at the point of declaration. 271 272-- For object declarations, the flag is set when an address clause for the 273-- object is encountered. Legality checks on the address expression only take 274-- place at the freeze point of the object. 275 276-- Most types have an explicit freeze node, because they cannot be elaborated 277-- until all representation and operational items that apply to them have been 278-- analyzed. Private types and incomplete types have the flag set as well, as 279-- do task and protected types. 280 281-- Implicit base types created for type derivations, as well as classwide 282-- types created for all tagged types, have the flag set. 283 284-- If a subprogram has an access parameter whose designated type is incomplete 285-- the subprogram has the flag set. 286 287----------------------- 288-- Entity Attributes -- 289----------------------- 290 291-- This section contains a complete list of the attributes that are defined 292-- on entities. Some attributes apply to all entities, others only to certain 293-- kinds of entities. In the latter case the attribute should only be set or 294-- accessed if the Ekind field indicates an appropriate entity. 295 296-- There are two kinds of attributes that apply to entities, stored and 297-- synthesized. Stored attributes correspond to a field or flag in the entity 298-- itself. Such attributes are identified in the table below by giving the 299-- field or flag in the attribute that is used to hold the attribute value. 300-- Synthesized attributes are not stored directly, but are rather computed as 301-- needed from other attributes, or from information in the tree. These are 302-- marked "synthesized" in the table below. The stored attributes have both 303-- access functions and set procedures to set the corresponding values, while 304-- synthesized attributes have only access functions. 305 306-- Note: in the case of Node, Uint, or Elist fields, there are cases where the 307-- same physical field is used for different purposes in different entities, 308-- so these access functions should only be referenced for the class of 309-- entities in which they are defined as being present. Flags are not 310-- overlapped in this way, but nevertheless as a matter of style and 311-- abstraction (which may or may not be checked by assertions in the 312-- body), this restriction should be observed for flag fields as well. 313 314-- Note: certain of the attributes on types apply only to base types, and 315-- are so noted by the notation [base type only]. These are cases where the 316-- attribute of any subtype is the same as the attribute of the base type. 317-- The attribute can be referenced on a subtype (and automatically retrieves 318-- the value from the base type). However, it is an error to try to set the 319-- attribute on other than the base type, and if assertions are enabled, 320-- an attempt to set the attribute on a subtype will raise an assert error. 321 322-- Other attributes are noted as applying to the [implementation base type 323-- only]. These are representation attributes which must always apply to a 324-- full non-private type, and where the attributes are always on the full 325-- type. The attribute can be referenced on a subtype (and automatically 326-- retries the value from the implementation base type). However, it is an 327-- error to try to set the attribute on other than the implementation base 328-- type, and if assertions are enabled, an attempt to set the attribute on a 329-- subtype will raise an assert error. 330 331-- Abstract_States (Elist25) 332-- Defined for E_Package entities. Contains a list of all the abstract 333-- states declared by the related package. 334 335-- Accept_Address (Elist21) 336-- Defined in entries. If an accept has a statement sequence, then an 337-- address variable is created, which is used to hold the address of the 338-- parameters, as passed by the runtime. Accept_Address holds an element 339-- list which represents a stack of entities for these address variables. 340-- The current entry is the top of the stack, which is the last element 341-- on the list. A stack is required to handle the case of nested select 342-- statements referencing the same entry. 343 344-- Access_Disp_Table (Elist16) [implementation base type only] 345-- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged 346-- types to point to their dispatch tables. The first two entities are 347-- associated with the primary dispatch table: 1) primary dispatch table 348-- with user-defined primitives 2) primary dispatch table with predefined 349-- primitives. For each interface type covered by the tagged type we also 350-- have: 3) secondary dispatch table with thunks of primitives covering 351-- user-defined interface primitives, 4) secondary dispatch table with 352-- thunks of predefined primitives, 5) secondary dispatch table with user 353-- defined primitives, and 6) secondary dispatch table with predefined 354-- primitives. The last entity of this list is an access type declaration 355-- used to expand dispatching calls through the primary dispatch table. 356-- For an untagged record, contains No_Elist. 357 358-- Activation_Record_Component (Node31) 359-- Defined in E_Variable, E_Constant, E_Loop_Parameter, E_In_Parameter, 360-- E_Out_Parameter, E_In_Out_Parameter nodes. Used only if we are in 361-- Opt.Unnest_Subprogram_Mode, in which case for the case of an uplevel 362-- referenced entity, this field contains the entity for the component 363-- in the generated ARECnT activation record (Exp_Unst for details). 364 365-- Actual_Subtype (Node17) 366-- Defined in variables, constants, and formal parameters. This is the 367-- subtype imposed by the value of the object, as opposed to its nominal 368-- subtype, which is imposed by the declaration. The actual subtype 369-- differs from the nominal one when the latter is indefinite (as in the 370-- case of an unconstrained formal parameter, or a variable declared 371-- with an unconstrained type and an initial value). The nominal subtype 372-- is the Etype entry for the entity. The Actual_Subtype field is set 373-- only if the actual subtype differs from the nominal subtype. If the 374-- actual and nominal subtypes are the same, then the Actual_Subtype 375-- field is Empty, and Etype indicates both types. 376-- 377-- For objects, the Actual_Subtype is set only if this is a discriminated 378-- type. For arrays, the bounds of the expression are obtained and the 379-- Etype of the object is directly the constrained subtype. This is 380-- rather irregular, and the semantic checks that depend on the nominal 381-- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv). 382 383-- Address_Clause (synthesized) 384-- Applies to entries, objects and subprograms. Set if an address clause 385-- is present which references the object or subprogram and points to 386-- the N_Attribute_Definition_Clause node. Empty if no Address clause. 387-- The expression in the address clause is always a constant that is 388-- defined before the entity to which the address clause applies. 389-- Note: The backend references this field in E_Task_Type entities??? 390 391-- Address_Taken (Flag104) 392-- Defined in all entities. Set if the Address or Unrestricted_Access 393-- attribute is applied directly to the entity, i.e. the entity is the 394-- entity of the prefix of the attribute reference. Also set if the 395-- entity is the second argument of an Asm_Input or Asm_Output attribute, 396-- as the construct may entail taking its address. Used by the backend to 397-- make sure that the address can be meaningfully taken, and also in the 398-- case of subprograms to control output of certain warnings. 399 400-- Aft_Value (synthesized) 401-- Applies to fixed and decimal types. Computes a universal integer that 402-- holds value of the Aft attribute for the type. 403 404-- Alias (Node18) 405-- Defined in overloadable entities (literals, subprograms, entries) and 406-- subprograms that cover a primitive operation of an abstract interface 407-- (that is, subprograms with the Interface_Alias attribute). In case of 408-- overloaded entities it points to the parent subprogram of a derived 409-- subprogram. In case of abstract interface subprograms it points to the 410-- subprogram that covers the abstract interface primitive. Also used for 411-- a subprogram renaming, where it points to the renamed subprogram. For 412-- an inherited operation (of a type extension) that is overridden in a 413-- private part, the Alias is the overriding operation. In this fashion a 414-- call from outside the package ends up executing the new body even if 415-- non-dispatching, and a call from inside calls the overriding operation 416-- because it hides the implicit one. Alias is always empty for entries. 417 418-- Alignment (Uint14) 419-- Defined in entities for types and also in constants, variables 420-- (including exceptions where it refers to the static data allocated for 421-- an exception), loop parameters, and formal parameters. This indicates 422-- the desired alignment for a type, or the actual alignment for an 423-- object. A value of zero (Uint_0) indicates that the alignment has not 424-- been set yet. The alignment can be set by an explicit alignment 425-- clause, or set by the front-end in package Layout, or set by the 426-- back-end as part of the back-end back-annotation process. The 427-- alignment field is also defined in E_Exception entities, but there it 428-- is used only by the back-end for back annotation. 429 430-- Alignment_Clause (synthesized) 431-- Applies to all entities for types and objects. If an alignment 432-- attribute definition clause is present for the entity, then this 433-- function returns the N_Attribute_Definition clause that specifies the 434-- alignment. If no alignment clause applies to the type, then the call 435-- to this function returns Empty. Note that the call can return a 436-- non-Empty value even if Has_Alignment_Clause is not set (happens with 437-- subtype and derived type declarations). Note also that a record 438-- definition clause with an (obsolescent) mod clause is converted 439-- into an attribute definition clause for this purpose. 440 441-- Anonymous_Master (Node36) 442-- Defined in the entities of non-generic packages, subprograms and their 443-- corresponding bodies. Contains the entity of a special heterogeneous 444-- finalization master that services most anonymous access-to-controlled 445-- allocations that occur within the unit. 446 447-- Anonymous_Object (Node30) 448-- Present in protected and task type entities. Contains the entity of 449-- the anonymous object created for a single protected or task type. 450 451-- Associated_Entity (Node37) 452-- Defined in all entities. This field is similar to Associated_Node, but 453-- applied to entities. The attribute links an entity from the generic 454-- template with its corresponding entity in the analyzed generic copy. 455-- The global references mechanism relies on the Associated_Entity to 456-- infer the context. 457 458-- Associated_Formal_Package (Node12) 459-- Defined in packages that are the actuals of formal_packages. Points 460-- to the entity in the declaration for the formal package. 461 462-- Associated_Node_For_Itype (Node8) 463-- Defined in all type and subtype entities. Set non-Empty only for 464-- Itypes. Set to point to the associated node for the Itype, i.e. 465-- the node whose elaboration generated the Itype. This is used for 466-- copying trees, to determine whether or not to copy an Itype, and 467-- also for accessibility checks on anonymous access types. This 468-- node is typically an object declaration, component declaration, 469-- type or subtype declaration. 470 471-- For an access discriminant in a type declaration, the associated_ 472-- node_for_itype is the corresponding discriminant specification. 473 474-- For an access parameter it is the enclosing subprogram declaration. 475 476-- For an access_to_protected_subprogram parameter it is the declaration 477-- of the corresponding formal parameter. 478-- 479-- Itypes have no explicit declaration, and therefore are not attached to 480-- the tree: their Parent field is always empty. The Associated_Node_For_ 481-- Itype is the only way to determine the construct that leads to the 482-- creation of a given itype entity. 483 484-- Associated_Storage_Pool (Node22) [root type only] 485-- Defined in simple and general access type entities. References the 486-- storage pool to be used for the corresponding collection. A value of 487-- Empty means that the default pool is to be used. This is defined 488-- only in the root type, since derived types must have the same pool 489-- as the parent type. 490 491-- Barrier_Function (Node12) 492-- Defined in protected entries and entry families. This is the 493-- subprogram declaration for the body of the function that returns 494-- the value of the entry barrier. 495 496-- Base_Type (synthesized) 497-- Applies to all type and subtype entities. Returns the base type of a 498-- type or subtype. The base type of a type is the type itself. The base 499-- type of a subtype is the type that it constrains (which is always 500-- a type entity, not some other subtype). Note that in the case of a 501-- subtype of a private type, it is possible for the base type attribute 502-- to return a private type, even if the subtype to which it applies is 503-- non-private. See also Implementation_Base_Type. Note: it is allowed to 504-- apply Base_Type to other than a type, in which case it simply returns 505-- the entity unchanged. 506 507-- Block_Node (Node11) 508-- Defined in block entities. Points to the identifier in the 509-- Block_Statement itself. Used when retrieving the block construct 510-- for finalization purposes, The block entity has an implicit label 511-- declaration in the enclosing declarative part, and has otherwise 512-- no direct connection in the tree with the block statement. The 513-- link is to the identifier (which is an occurrence of the entity) 514-- and not to the block_statement itself, because the statement may 515-- be rewritten, e.g. in the process of removing dead code. 516 517-- Body_Entity (Node19) 518-- Defined in package and generic package entities, points to the 519-- corresponding package body entity if one is present. 520 521-- Body_Needed_For_SAL (Flag40) 522-- Defined in package and subprogram entities that are compilation 523-- units. Indicates that the source for the body must be included 524-- when the unit is part of a standalone library. 525 526-- Body_References (Elist16) 527-- Defined in abstract state entities. Contains an element list of 528-- references (identifiers) that appear in a package body whose spec 529-- defines the related state. If the body refines the said state, all 530-- references on this list are illegal due to the visible refinement. 531 532-- BIP_Initialization_Call (Node29) 533-- Defined in constants and variables whose corresponding declaration 534-- is wrapped in a transient block and the inital value is provided by 535-- a build-in-place function call. Contains the relocated build-in-place 536-- call after the expansion has decoupled the call from the object. This 537-- attribute is used by the finalization machinery to insert cleanup code 538-- for all additional transient variables found in the transient block. 539 540-- C_Pass_By_Copy (Flag125) [implementation base type only] 541-- Defined in record types. Set if a pragma Convention for the record 542-- type specifies convention C_Pass_By_Copy. This convention name is 543-- treated as identical in all respects to convention C, except that 544-- if it is specified for a record type, then the C_Pass_By_Copy flag 545-- is set, and if a foreign convention subprogram has a formal of the 546-- corresponding type, then the parameter passing mechanism will be 547-- set to By_Copy (unless specifically overridden by an Import or 548-- Export pragma). 549 550-- Can_Never_Be_Null (Flag38) 551-- This flag is defined in all entities. It is set in an object which can 552-- never have a null value. Set for constant access values initialized to 553-- a non-null value. This is also set for all access parameters in Ada 83 554-- and Ada 95 modes, and for access parameters that explicitly exclude 555-- exclude null in Ada 2005 mode. 556-- 557-- This is used to avoid unnecessary resetting of the Is_Known_Non_Null 558-- flag for such entities. In Ada 2005 mode, this is also used when 559-- determining subtype conformance of subprogram profiles to ensure 560-- that two formals have the same null-exclusion status. 561-- 562-- This is also set on some access types, e.g. the Etype of the anonymous 563-- access type of a controlling formal. 564 565-- Can_Use_Internal_Rep (Flag229) [base type only] 566-- Defined in Access_Subprogram_Kind nodes. This flag is set by the 567-- front end and used by the backend. False means that the backend 568-- must represent the type in the same way as Convention-C types (and 569-- other foreign-convention types). On many targets, this means that 570-- the backend will use dynamically generated trampolines for nested 571-- subprograms. True means that the backend can represent the type in 572-- some internal way. On the aforementioned targets, this means that the 573-- backend will not use dynamically generated trampolines. This flag 574-- must be False if Has_Foreign_Convention is True; otherwise, the front 575-- end is free to set the policy. 576-- 577-- Setting this False in all cases corresponds to the traditional back 578-- end strategy, where all access-to-subprogram types are represented the 579-- same way, independent of the Convention. For further details, see also 580-- Always_Compatible_Rep in Targparm. 581-- 582-- Efficiency note: On targets that use dynamically generated 583-- trampolines, False generally favors efficiency of top-level 584-- subprograms, whereas True generally favors efficiency of nested 585-- ones. On other targets, this flag has little or no effect on 586-- efficiency. The front end should take this into account. In 587-- particular, pragma Favor_Top_Level gives a hint that the flag 588-- should be False. 589-- 590-- Note: We considered using Convention-C for this purpose, but we need 591-- this separate flag, because Convention-C implies that in the case of 592-- P'[Unrestricted_]Access, P also have convention C. Sometimes we want 593-- to have Can_Use_Internal_Rep False for an access type, but allow P to 594-- have convention Ada. 595 596-- Chars (Name1) 597-- Defined in all entities. This field contains an entry into the names 598-- table that has the character string of the identifier, character 599-- literal or operator symbol. See Namet for further details. Note that 600-- throughout the processing of the front end, this name is the simple 601-- unqualified name. However, just before the backend is called, a call 602-- is made to Qualify_All_Entity_Names. This causes entity names to be 603-- qualified using the encoding described in exp_dbug.ads, and from that 604-- point (including post backend steps, e.g. cross-reference generation), 605-- the entities will contain the encoded qualified names. 606 607-- Checks_May_Be_Suppressed (Flag31) 608-- Defined in all entities. Set if a pragma Suppress or Unsuppress 609-- mentions the entity specifically in the second argument. If this 610-- flag is set the Global_Entity_Suppress and Local_Entity_Suppress 611-- tables must be consulted to determine if there actually is an active 612-- Suppress or Unsuppress pragma that applies to the entity. 613 614-- Class_Wide_Preconds (List38) 615-- Defined on subprograms. Holds the list of class-wide precondition 616-- functions inherited from ancestors. Each such function is an 617-- instantiation of the generic function generated from an explicit 618-- aspect specification for a class-wide precondition. A type is an 619-- ancestor of itself, and therefore a root type has such an instance 620-- on its own list. 621 622-- Class_Wide_Postconds (List39) 623-- Ditto for class-wide postconditions. 624 625-- Class_Wide_Type (Node9) 626-- Defined in all type entities. For a tagged type or subtype, returns 627-- the corresponding implicitly declared class-wide type. For a 628-- class-wide type, returns itself. Set to Empty for untagged types. 629 630-- Cloned_Subtype (Node16) 631-- Defined in E_Record_Subtype and E_Class_Wide_Subtype entities. 632-- Each such entity can either have a Discriminant_Constraint, in 633-- which case it represents a distinct type from the base type (and 634-- will have a list of components and discrimants in the list headed by 635-- First_Entity) or else no such constraint, in which case it will be a 636-- copy of the base type. 637-- 638-- o Each element of the list in First_Entity is copied from the base 639-- type; in that case, this field is Empty. 640-- 641-- o The list in First_Entity is shared with the base type; in that 642-- case, this field points to that entity. 643-- 644-- A record or classwide subtype may also be a copy of some other 645-- subtype and share the entities in the First_Entity with that subtype. 646-- In that case, this field points to that subtype. 647-- 648-- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides 649-- this field. Note that this field ONLY appears in subtype entries, not 650-- in type entries, it is not defined, and it is an error to reference 651-- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity. 652 653-- Comes_From_Source 654-- This flag appears on all nodes, including entities, and indicates 655-- that the node was created by the scanner or parser from the original 656-- source. Thus for entities, it indicates that the entity is defined 657-- in the original source program. 658 659-- Component_Alignment (special field) [base type only] 660-- Defined in array and record entities. Contains a value of type 661-- Component_Alignment_Kind indicating the alignment of components. 662-- Set to Calign_Default normally, but can be overridden by use of 663-- the Component_Alignment pragma. Note: this field is currently 664-- stored in a non-standard way, see body for details. 665 666-- Component_Bit_Offset (Uint11) 667-- Defined in record components (E_Component, E_Discriminant) if a 668-- component clause applies to the component. First bit position of 669-- given component, computed from the first bit and position values 670-- given in the component clause. A value of No_Uint means that the 671-- value is not yet known. The value can be set by the appearance of 672-- an explicit component clause in a record representation clause, 673-- or it can be set by the front-end in package Layout, or it can be 674-- set by the backend. By the time backend processing is completed, 675-- this field is always set. A negative value is used to represent 676-- a value which is not known at compile time, and must be computed 677-- at run-time (this happens if fields of a record have variable 678-- lengths). See package Layout for details of these values. 679-- 680-- Note: Component_Bit_Offset is redundant with respect to the fields 681-- Normalized_First_Bit and Normalized_Position, and could in principle 682-- be eliminated, but it is convenient in several situations, including 683-- use in the backend, to have this redundant field. 684 685-- Component_Clause (Node13) 686-- Defined in record components and discriminants. If a record 687-- representation clause is present for the corresponding record type a 688-- that specifies a position for the component, then the Component_Clause 689-- field of the E_Component entity points to the N_Component_Clause node. 690-- Set to Empty if no record representation clause was present, or if 691-- there was no specification for this component. 692 693-- Component_Size (Uint22) [implementation base type only] 694-- Defined in array types. It contains the component size value for 695-- the array. A value of No_Uint means that the value is not yet set. 696-- The value can be set by the use of a component size clause, or 697-- by the front end in package Layout, or by the backend. A negative 698-- value is used to represent a value which is not known at compile 699-- time, and must be computed at run-time (this happens if the type 700-- of the component has a variable length size). See package Layout 701-- for details of these values. 702 703-- Component_Type (Node20) [implementation base type only] 704-- Defined in array types and string types. References component type. 705 706-- Contains_Ignored_Ghost_Code (Flag279) 707-- Defined in blocks, packages and their bodies, subprograms and their 708-- bodies. Set if the entity contains any ignored Ghost code in the form 709-- of declaration, procedure call, assignment statement or pragma. 710 711-- Contract (Node34) 712-- Defined in constant, entry, entry family, operator, [generic] package, 713-- package body, protected type, [generic] subprogram, subprogram body, 714-- variable and task type entities. Points to the contract of the entity, 715-- holding various assertion items and data classifiers. 716 717-- Contract_Wrapper (Node25) 718-- Defined in entry and entry family entities. Set only when the entry 719-- [family] has contract cases, preconditions, and/or postconditions. 720-- Contains the entity of a wrapper procedure which encapsulates the 721-- original entry and implements precondition/postcondition semantics. 722 723-- Corresponding_Concurrent_Type (Node18) 724-- Defined in record types that are constructed by the expander to 725-- represent task and protected types (Is_Concurrent_Record_Type flag 726-- set). Points to the entity for the corresponding task type or the 727-- protected type. 728 729-- Corresponding_Discriminant (Node19) 730-- Defined in discriminants of a derived type, when the discriminant is 731-- used to constrain a discriminant of the parent type. Points to the 732-- corresponding discriminant in the parent type. Otherwise it is Empty. 733 734-- Corresponding_Equality (Node30) 735-- Defined in function entities for implicit inequality operators. 736-- Denotes the explicit or derived equality operation that creates 737-- the implicit inequality. Note that this field is not present in 738-- other function entities, only in implicit inequality routines, 739-- where Comes_From_Source is always False. 740 741-- Corresponding_Protected_Entry (Node18) 742-- Defined in subprogram bodies. Set for subprogram bodies that implement 743-- a protected type entry to point to the entity for the entry. 744 745-- Corresponding_Record_Type (Node18) 746-- Defined in protected and task types and subtypes. References the 747-- entity for the corresponding record type constructed by the expander 748-- (see Exp_Ch9). This type is used to represent values of the task type. 749 750-- Corresponding_Remote_Type (Node22) 751-- Defined in record types that describe the fat pointer structure for 752-- Remote_Access_To_Subprogram types. References the original access 753-- to subprogram type. 754 755-- CR_Discriminant (Node23) 756-- Defined in discriminants of concurrent types. Denotes the homologous 757-- discriminant of the corresponding record type. The CR_Discriminant is 758-- created at the same time as the discriminal, and used to replace 759-- occurrences of the discriminant within the type declaration. 760 761-- Current_Use_Clause (Node27) 762-- Defined in packages and in types. For packages, denotes the use 763-- package clause currently in scope that makes the package use_visible. 764-- For types, it denotes the use_type clause that makes the operators of 765-- the type visible. Used for more precise warning messages on redundant 766-- use clauses. 767 768-- Current_Value (Node9) 769-- Defined in all object entities. Set in E_Variable, E_Constant, formal 770-- parameters and E_Loop_Parameter entities if we have trackable current 771-- values. Set non-Empty if the (constant) current value of the variable 772-- is known, This value is valid only for references from the same 773-- sequential scope as the entity. The sequential scope of an entity 774-- includes the immediate scope and any contained scopes that are package 775-- specs, package bodies, blocks (at any nesting level) or statement 776-- sequences in IF or loop statements. 777-- 778-- Another related use of this field is to record information about the 779-- value obtained from an IF or WHILE statement condition. If the IF or 780-- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ", 781-- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a 782-- Current_Value field, RELOP is one of the six relational operators, and 783-- VAL is a compile-time known value then the Current_Value field of OBJ 784-- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node 785-- of the relevant construct, and the Condition field of this can be 786-- consulted to give information about the value of OBJ. For more details 787-- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition. 788 789-- Debug_Info_Off (Flag166) 790-- Defined in all entities. Set if a pragma Suppress_Debug_Info applies 791-- to the entity, or if internal processing in the compiler determines 792-- that suppression of debug information is desirable. Note that this 793-- flag is only for use by the front end as part of the processing for 794-- determining if Needs_Debug_Info should be set. The backend should 795-- always test Needs_Debug_Info, it should never test Debug_Info_Off. 796 797-- Debug_Renaming_Link (Node25) 798-- Used to link the variable associated with a debug renaming declaration 799-- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for 800-- details of the use of this field. 801 802-- Declaration_Node (synthesized) 803-- Applies to all entities. Returns the tree node for the construct that 804-- declared the entity. Normally this is just the Parent of the entity. 805-- One exception arises with child units, where the parent of the entity 806-- is a selected component/defining program unit name. Another exception 807-- is that if the entity is an incomplete type that has been completed or 808-- a private type, then we obtain the declaration node denoted by the 809-- full type, i.e. the full type declaration node. Also note that for 810-- subprograms, this returns the {function,procedure}_specification, not 811-- the subprogram_declaration. 812 813-- Default_Aspect_Component_Value (Node19) [base type only] 814-- Defined in array types. Holds the static value specified in a 815-- Default_Component_Value aspect specification for the array type, 816-- or inherited on derivation. 817 818-- Default_Aspect_Value (Node19) [base type only] 819-- Defined in scalar types. Holds the static value specified in a 820-- Default_Value aspect specification for the type, or inherited 821-- on derivation. 822 823-- Default_Expr_Function (Node21) 824-- Defined in parameters. It holds the entity of the parameterless 825-- function that is built to evaluate the default expression if it is 826-- more complex than a simple identifier or literal. For the latter 827-- simple cases or if there is no default value, this field is Empty. 828 829-- Default_Expressions_Processed (Flag108) 830-- A flag in subprograms (functions, operators, procedures) and in 831-- entries and entry families used to indicate that default expressions 832-- have been processed and to avoid multiple calls to process the 833-- default expressions (see Freeze.Process_Default_Expressions), which 834-- would not only waste time, but also generate false error messages. 835 836-- Default_Init_Cond_Procedure (synthesized) 837-- Defined in all types. Set for private [sub]types subject to pragma 838-- Default_Initial_Condition, their corresponding full views and derived 839-- types with at least one parent subject to the pragma. Contains the 840-- entity of the procedure which takes a single argument of the given 841-- type and verifies the assumption of the pragma. 842-- 843-- Note: the reason this is marked as a synthesized attribute is that the 844-- way this is stored is as an element of the Subprograms_For_Type field. 845 846-- Default_Value (Node20) 847-- Defined in formal parameters. Points to the node representing the 848-- expression for the default value for the parameter. Empty if the 849-- parameter has no default value (which is always the case for OUT 850-- and IN OUT parameters in the absence of errors). 851 852-- Delay_Cleanups (Flag114) 853-- Defined in entities that have finalization lists (subprograms 854-- blocks, and tasks). Set if there are pending generic body 855-- instantiations for the corresponding entity. If this flag is 856-- set, then generation of cleanup actions for the corresponding 857-- entity must be delayed, since the insertion of the generic body 858-- may affect cleanup generation (see Inline for further details). 859 860-- Delay_Subprogram_Descriptors (Flag50) 861-- Defined in entities for which exception subprogram descriptors 862-- are generated (subprograms, package declarations and package 863-- bodies). Defined if there are pending generic body instantiations 864-- for the corresponding entity. If this flag is set, then generation 865-- of the subprogram descriptor for the corresponding enities must 866-- be delayed, since the insertion of the generic body may add entries 867-- to the list of handlers. 868-- 869-- Note: for subprograms, Delay_Subprogram_Descriptors is set if and 870-- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a 871-- a block (in which case Delay_Subprogram_Descriptors is set for the 872-- containing subprogram). In addition Delay_Subprogram_Descriptors is 873-- set for a library level package declaration or body which contains 874-- delayed instantiations (in this case the descriptor refers to the 875-- enclosing elaboration procedure). 876 877-- Delta_Value (Ureal18) 878-- Defined in fixed and decimal types. Points to a universal real 879-- that holds value of delta for the type, as given in the declaration 880-- or as inherited by a subtype or derived type. 881 882-- Dependent_Instances (Elist8) 883-- Defined in packages that are instances. Holds list of instances 884-- of inner generics. Used to place freeze nodes for those instances 885-- after that of the current one, i.e. after the corresponding generic 886-- bodies. 887 888-- Depends_On_Private (Flag14) 889-- Defined in all type entities. Set if the type is private or if it 890-- depends on a private type. 891 892-- Derived_Type_Link (Node31) 893-- Defined in all type and subtype entries. Set in a base type if 894-- a derived type declaration is encountered which derives from 895-- this base type or one of its subtypes, and there are already 896-- primitive operations declared. In this case, it references the 897-- entity for the type declared by the derived type declaration. 898-- For example: 899-- 900-- type R is ... 901-- subtype RS is R ... 902-- ... 903-- type G is new RS ... 904-- 905-- In this case, if primitive operations have been declared for R, at 906-- the point of declaration of G, then the Derived_Type_Link of R is set 907-- to point to the entity for G. This is used to generate warnings for 908-- rep clauses that appear later on for R, which might result in an 909-- unexpected implicit conversion operation. 910-- 911-- Note: if there is more than one such derived type, the link will point 912-- to the last one (this is only used in generating warning messages). 913 914-- Designated_Type (synthesized) 915-- Applies to access types. Returns the designated type. Differs from 916-- Directly_Designated_Type in that if the access type refers to an 917-- incomplete type, and the full type is available, then this full type 918-- is returned instead of the incomplete type. 919 920-- Digits_Value (Uint17) 921-- Defined in floating point types and subtypes and decimal types and 922-- subtypes. Contains the Digits value specified in the declaration. 923 924-- Direct_Primitive_Operations (Elist10) 925-- Defined in tagged types and subtypes (including synchronized types), 926-- in tagged private types and in tagged incomplete types. Element list 927-- of entities for primitive operations of the tagged type. Not defined 928-- in untagged types. In order to follow the C++ ABI, entities of 929-- primitives that come from source must be stored in this list in the 930-- order of their occurrence in the sources. For incomplete types the 931-- list is always empty. 932-- When expansion is disabled the corresponding record type of a 933-- synchronized type is not constructed. In that case, such types 934-- carry this attribute directly, for ASIS use. 935 936-- Directly_Designated_Type (Node20) 937-- Defined in access types. This field points to the type that is 938-- directly designated by the access type. In the case of an access 939-- type to an incomplete type, this field references the incomplete 940-- type. Directly_Designated_Type is typically used in implementing the 941-- static semantics of the language; in implementing dynamic semantics, 942-- we typically want the full view of the designated type. The function 943-- Designated_Type obtains this full type in the case of access to an 944-- incomplete type. 945 946-- Disable_Controlled (Flag253) 947-- Present in all entities. Set for a controlled type (Is_Controlled flag 948-- set) if the aspect Disable_Controlled is active for the type. 949 950-- Discard_Names (Flag88) 951-- Defined in types and exception entities. Set if pragma Discard_Names 952-- applies to the entity. It is also set for declarative regions and 953-- package specs for which a Discard_Names pragma with zero arguments 954-- has been encountered. The purpose of setting this flag is to be able 955-- to set the Discard_Names attribute on enumeration types declared 956-- after the pragma within the same declarative region. This flag is 957-- set to False if a Keep_Names pragma appears for an enumeration type. 958 959-- Discriminal (Node17) 960-- Defined in discriminants (Discriminant formal: GNAT's first 961-- coinage). The entity used as a formal parameter that corresponds 962-- to a discriminant. See section "Handling of Discriminants" for 963-- full details of the use of discriminals. 964 965-- Discriminal_Link (Node10) 966-- Defined in E_In_Parameter or E_Constant entities. For discriminals, 967-- points back to corresponding discriminant. For other entities, must 968-- remain Empty. 969 970-- Discriminant_Checking_Func (Node20) 971-- Defined in components. Points to the defining identifier of the 972-- function built by the expander returns a Boolean indicating whether 973-- the given record component exists for the current discriminant 974-- values. 975 976-- Discriminant_Constraint (Elist21) 977-- Defined in entities whose Has_Discriminants flag is set (concurrent 978-- types, subtypes, record types and subtypes, private types and 979-- subtypes, limited private types and subtypes and incomplete types). 980-- It is an error to reference the Discriminant_Constraint field if 981-- Has_Discriminants is False. 982-- 983-- If the Is_Constrained flag is set, Discriminant_Constraint points 984-- to an element list containing the discriminant constraints in the 985-- same order in which the discriminants are declared. 986-- 987-- If the Is_Constrained flag is not set but the discriminants of the 988-- unconstrained type have default initial values then this field 989-- points to an element list giving these default initial values in 990-- the same order in which the discriminants are declared. Note that 991-- in this case the entity cannot be a tagged record type, because 992-- discriminants in this case cannot have defaults. 993-- 994-- If the entity is a tagged record implicit type, then this field is 995-- inherited from the first subtype (so that the itype is subtype 996-- conformant with its first subtype, which is needed when the first 997-- subtype overrides primitive operations inherited by the implicit 998-- base type). 999-- 1000-- In all other cases Discriminant_Constraint contains the empty 1001-- Elist (ie it is initialized with a call to New_Elmt_List). 1002 1003-- Discriminant_Default_Value (Node20) 1004-- Defined in discriminants. Points to the node representing the 1005-- expression for the default value of the discriminant. Set to 1006-- Empty if the discriminant has no default value. 1007 1008-- Discriminant_Number (Uint15) 1009-- Defined in discriminants. Gives the ranking of a discriminant in 1010-- the list of discriminants of the type, i.e. a sequential integer 1011-- index starting at 1 and ranging up to number of discriminants. 1012 1013-- Dispatch_Table_Wrappers (Elist26) [implementation base type only] 1014-- Defined in E_Record_Type and E_Record_Subtype entities. Set in library 1015-- level tagged type entities if we are generating statically allocated 1016-- dispatch tables. Points to the list of dispatch table wrappers 1017-- associated with the tagged type. For an untagged record, contains 1018-- No_Elist. 1019 1020-- DTC_Entity (Node16) 1021-- Defined in function and procedure entities. Set to Empty unless 1022-- the subprogram is dispatching in which case it references the 1023-- Dispatch Table pointer Component. For regular Ada tagged this, this 1024-- is the _Tag component. For CPP_Class types and their descendants, 1025-- this points to the component entity in the record that holds the 1026-- Vtable pointer for the Vtable containing the entry referencing the 1027-- subprogram. 1028 1029-- DT_Entry_Count (Uint15) 1030-- Defined in E_Component entities. Only used for component marked 1031-- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table) 1032 1033-- DT_Offset_To_Top_Func (Node25) 1034-- Defined in E_Component entities. Only used for component marked 1035-- Is_Tag. If present it stores the Offset_To_Top function used to 1036-- provide this value in tagged types whose ancestor has discriminants. 1037 1038-- DT_Position (Uint15) 1039-- Defined in function and procedure entities which are dispatching 1040-- (should not be referenced without first checking that flag 1041-- Is_Dispatching_Operation is True). Contains the offset into 1042-- the Vtable for the entry that references the subprogram. 1043 1044-- Ekind (Ekind) 1045-- Defined in all entities. Contains a value of the enumeration type 1046-- Entity_Kind declared in a subsequent section in this spec. 1047 1048-- Elaborate_Body_Desirable (Flag210) 1049-- Defined in package entities. Set if the elaboration circuitry detects 1050-- a case where there is a package body that modifies one or more visible 1051-- entities in the package spec and there is no explicit Elaborate_Body 1052-- pragma for the package. This information is passed on to the binder, 1053-- which attempts, but does not promise, to elaborate the body as close 1054-- to the spec as possible. 1055 1056-- Elaboration_Entity (Node13) 1057-- Defined in generic and non-generic package and subprogram entities. 1058-- This is a counter associated with the unit that is initially set to 1059-- zero, is incremented when an elaboration request for the unit is 1060-- made, and is decremented when a finalization request for the unit 1061-- is made. This is used for three purposes. First, it is used to 1062-- implement access before elaboration checks (the counter must be 1063-- non-zero to call a subprogram at elaboration time). Second, it is 1064-- used to guard against repeated execution of the elaboration code. 1065-- Third, it is used to ensure that the finalization code is executed 1066-- only after all clients have requested it. 1067-- 1068-- Note that we always allocate this counter, and set this field, but 1069-- we do not always actually use it. It is only used if it is needed 1070-- for access before elaboration use (see Elaboration_Entity_Required 1071-- flag) or if either the spec or the body has elaboration code. If 1072-- neither of these two conditions holds, then the entity is still 1073-- allocated (since we don't know early enough whether or not there 1074-- is elaboration code), but is simply not used for any purpose. 1075 1076-- Elaboration_Entity_Required (Flag174) 1077-- Defined in generic and non-generic package and subprogram entities. 1078-- Set only if Elaboration_Entity is non-Empty to indicate that the 1079-- counter is required to be non-zero even if there is no other 1080-- elaboration code. This occurs when the Elaboration_Entity counter 1081-- is used for access before elaboration checks. If the counter is 1082-- only used to prevent multiple execution of the elaboration code, 1083-- then if there is no other elaboration code, obviously there is no 1084-- need to set the flag. 1085 1086-- Encapsulating_State (Node32) 1087-- Defined in abstract state, constant and variable entities. Contains 1088-- the entity of an ancestor state or a single concurrent type whose 1089-- refinement utilizes this item as a constituent. 1090 1091-- Enclosing_Scope (Node18) 1092-- Defined in labels. Denotes the innermost enclosing construct that 1093-- contains the label. Identical to the scope of the label, except for 1094-- labels declared in the body of an accept statement, in which case the 1095-- entry_name is the Enclosing_Scope. Used to validate goto's within 1096-- accept statements. 1097 1098-- Entry_Accepted (Flag152) 1099-- Defined in E_Entry and E_Entry_Family entities. Set if there is 1100-- at least one accept for this entry in the task body. Used to 1101-- generate warnings for missing accepts. 1102 1103-- Entry_Bodies_Array (Node19) 1104-- Defined in protected types for which Has_Entries is true. 1105-- This is the defining identifier for the array of entry body 1106-- action procedures and barrier functions used by the runtime to 1107-- execute the user code associated with each entry. 1108 1109-- Entry_Cancel_Parameter (Node23) 1110-- Defined in blocks. This only applies to a block statement for 1111-- which the Is_Asynchronous_Call_Block flag is set. It 1112-- contains the defining identifier of an object that must be 1113-- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call 1114-- call in the cleanup handler added to the block by 1115-- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean 1116-- object for task entry calls and a Communications_Block object 1117-- in the case of protected entry calls. In both cases the objects 1118-- are declared in outer scopes to this block. 1119 1120-- Entry_Component (Node11) 1121-- Defined in formal parameters (in, in out and out parameters). Used 1122-- only for formals of entries. References the corresponding component 1123-- of the entry parameter record for the entry. 1124 1125-- Entry_Formal (Node16) 1126-- Defined in components of the record built to correspond to entry 1127-- parameters. This field points from the component to the formal. It 1128-- is the back pointer corresponding to Entry_Component. 1129 1130-- Entry_Index_Constant (Node18) 1131-- Defined in an entry index parameter. This is an identifier that 1132-- eventually becomes the name of a constant representing the index 1133-- of the entry family member whose entry body is being executed. Used 1134-- to expand references to the entry index specification identifier. 1135 1136-- Entry_Index_Type (synthesized) 1137-- Applies to an entry family. Denotes Etype of the subtype indication 1138-- in the entry declaration. Used to resolve the index expression in an 1139-- accept statement for a member of the family, and in the prefix of 1140-- 'COUNT when it applies to a family member. 1141 1142-- Entry_Parameters_Type (Node15) 1143-- Defined in entries. Points to the access-to-record type that is 1144-- constructed by the expander to hold a reference to the parameter 1145-- values. This reference is manipulated (as an address) by the 1146-- tasking runtime. The designated record represents a packaging 1147-- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration 1148-- for further details). Entry_Parameters_Type is Empty if the entry 1149-- has no parameters. 1150 1151-- Enumeration_Pos (Uint11) 1152-- Defined in enumeration literals. Contains the position number 1153-- corresponding to the value of the enumeration literal. 1154 1155-- Enumeration_Rep (Uint12) 1156-- Defined in enumeration literals. Contains the representation that 1157-- corresponds to the value of the enumeration literal. Note that 1158-- this is normally the same as Enumeration_Pos except in the presence 1159-- of representation clauses, where Pos will still represent the 1160-- position of the literal within the type and Rep will have be the 1161-- value given in the representation clause. 1162 1163-- Enumeration_Rep_Expr (Node22) 1164-- Defined in enumeration literals. Points to the expression in an 1165-- associated enumeration rep clause that provides the representation 1166-- value for this literal. Empty if no enumeration rep clause for this 1167-- literal (or if rep clause does not have an entry for this literal, 1168-- an error situation). This is also used to catch duplicate entries 1169-- for the same literal. 1170 1171-- Enum_Pos_To_Rep (Node23) 1172-- Defined in enumeration types (but not enumeration subtypes). Set to 1173-- Empty unless the enumeration type has a non-standard representation 1174-- (i.e. at least one literal has a representation value different from 1175-- its pos value). In this case, Enum_Pos_To_Rep is the entity for an 1176-- array constructed when the type is frozen that maps Pos values to 1177-- corresponding Rep values. The index type of this array is Natural, 1178-- and the component type is a suitable integer type that holds the 1179-- full range of representation values. 1180 1181-- Equivalent_Type (Node18) 1182-- Defined in class wide types and subtypes, access to protected 1183-- subprogram types, and in exception types. For a classwide type, it 1184-- is always Empty. For a class wide subtype, it points to an entity 1185-- created by the expander which gives the backend an understandable 1186-- equivalent of the class subtype with a known size (given by an 1187-- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further 1188-- details. For E_Exception_Type, this points to the record containing 1189-- the data necessary to represent exceptions (for further details, see 1190-- System.Standard_Library. For access_to_protected subprograms, it 1191-- denotes a record that holds pointers to the operation and to the 1192-- protected object. For remote Access_To_Subprogram types, it denotes 1193-- the record that is the fat pointer representation of an RAST. 1194 1195-- Esize (Uint12) 1196-- Defined in all types and subtypes, and also for components, constants, 1197-- and variables, including exceptions where it refers to the static data 1198-- allocated for an exception. Contains the Object_Size of the type or of 1199-- the object. A value of zero indicates that the value is not yet known. 1200-- 1201-- For the case of components where a component clause is present, the 1202-- value is the value from the component clause, which must be non- 1203-- negative (but may be zero, which is acceptable for the case of 1204-- a type with only one possible value). It is also possible for Esize 1205-- of a component to be set without a component clause defined, which 1206-- means that the component size is specified, but not the position. 1207-- See also RM_Size and the section on "Handling of Type'Size Values". 1208-- During backend processing, the value is back annotated for all zero 1209-- values, so that after the call to the backend, the value is set. 1210 1211-- Etype (Node5) 1212-- Defined in all entities. Represents the type of the entity, which 1213-- is itself another entity. For a type entity, points to the parent 1214-- type for a derived type, or if the type is not derived, points to 1215-- itself. For a subtype entity, Etype points to the base type. For 1216-- a class wide type, points to the corresponding specific type. For a 1217-- subprogram or subprogram type, Etype has the return type of a function 1218-- or is set to Standard_Void_Type to represent a procedure. The Etype 1219-- field of a package is also set to Standard_Void_Type. 1220-- 1221-- Note one obscure case: for pragma Default_Storage_Pool (null), the 1222-- Etype of the N_Null node is Empty. 1223 1224-- Extra_Accessibility (Node13) 1225-- Defined in formal parameters in the non-generic case. Normally Empty, 1226-- but if expansion is active, and a parameter is one for which a 1227-- dynamic accessibility check is required, then an extra formal of type 1228-- Natural is created (see description of field Extra_Formal), and the 1229-- Extra_Accessibility field of the formal parameter points to the entity 1230-- for this extra formal. Also defined in variables when compiling 1231-- receiving stubs. In this case, a non Empty value means that this 1232-- variable's accessibility depth has been transmitted by the caller and 1233-- must be retrieved through the entity designed by this field instead of 1234-- being computed. 1235 1236-- Extra_Accessibility_Of_Result (Node19) 1237-- Defined in (non-generic) Function, Operator, and Subprogram_Type 1238-- entities. Normally Empty, but if expansion is active, and a function 1239-- is one for which "the accessibility level of the result ... determined 1240-- by the point of call" (AI05-0234) is needed, then an extra formal of 1241-- subtype Natural is created (see description of field Extra_Formal), 1242-- and the Extra_Accessibility_Of_Result field of the function points to 1243-- the entity for this extra formal. 1244 1245-- Extra_Constrained (Node23) 1246-- Defined in formal parameters in the non-generic case. Normally Empty, 1247-- but if expansion is active and a parameter is one for which a dynamic 1248-- indication of its constrained status is required, then an extra formal 1249-- of type Boolean is created (see description of field Extra_Formal), 1250-- and the Extra_Constrained field of the formal parameter points to the 1251-- entity for this extra formal. Also defined in variables when compiling 1252-- receiving stubs. In this case, a non empty value means that this 1253-- variable's constrained status has been transmitted by the caller and 1254-- must be retrieved through the entity designed by this field instead of 1255-- being computed. 1256 1257-- Extra_Formal (Node15) 1258-- Defined in formal parameters in the non-generic case. Certain 1259-- parameters require extra implicit information to be passed (e.g. the 1260-- flag indicating if an unconstrained variant record argument is 1261-- constrained, and the accessibility level for access parameters). See 1262-- description of Extra_Constrained, Extra_Accessibility fields for 1263-- further details. Extra formal parameters are constructed to represent 1264-- these values, and chained to the end of the list of formals using the 1265-- Extra_Formal field (i.e. the Extra_Formal field of the last "real" 1266-- formal points to the first extra formal, and the Extra_Formal field of 1267-- each extra formal points to the next one, with Empty indicating the 1268-- end of the list of extra formals). Another case of Extra_Formal arises 1269-- in connection with unnesting of subprograms, where the ARECnF formal 1270-- that represents an activation record pointer is an extra formal. 1271 1272-- Extra_Formals (Node28) 1273-- Applies to subprograms and subprogram types, and also to entries 1274-- and entry families. Returns first extra formal of the subprogram 1275-- or entry. Returns Empty if there are no extra formals. 1276 1277-- Finalization_Master (Node23) [root type only] 1278-- Defined in access-to-controlled or access-to-class-wide types. The 1279-- field contains the entity of the finalization master which handles 1280-- dynamically allocated controlled objects referenced by the access 1281-- type. Empty for access-to-subprogram types. Empty for access types 1282-- whose designated type does not need finalization actions. 1283 1284-- Finalize_Storage_Only (Flag158) [base type only] 1285-- Defined in all types. Set on direct controlled types to which a 1286-- valid Finalize_Storage_Only pragma applies. This flag is also set on 1287-- composite types when they have at least one controlled component and 1288-- all their controlled components are Finalize_Storage_Only. It is also 1289-- inherited by type derivation except for direct controlled types where 1290-- the Finalize_Storage_Only pragma is required at each level of 1291-- derivation. 1292 1293-- Finalizer (Node28) 1294-- Applies to package declarations and bodies. Contains the entity of the 1295-- library-level program which finalizes all package-level controlled 1296-- objects. 1297 1298-- First_Component (synthesized) 1299-- Applies to incomplete, private, protected, record and task types. 1300-- Returns the first component by following the chain of declared 1301-- entities for the type a component is found (one with an Ekind of 1302-- E_Component). The discriminants are skipped. If the record is null, 1303-- then Empty is returned. 1304 1305-- First_Component_Or_Discriminant (synthesized) 1306-- Similar to First_Component, but discriminants are not skipped, so will 1307-- find the first discriminant if discriminants are present. 1308 1309-- First_Entity (Node17) 1310-- Defined in all entities which act as scopes to which a list of 1311-- associated entities is attached (blocks, class subtypes and types, 1312-- entries, functions, loops, packages, procedures, protected objects, 1313-- record types and subtypes, private types, task types and subtypes). 1314-- Points to a list of associated entities using the Next_Entity field 1315-- as a chain pointer with Empty marking the end of the list. 1316 1317-- First_Exit_Statement (Node8) 1318-- Defined in E_Loop entity. The exit statements for a loop are chained 1319-- (in reverse order of appearance) using this field to point to the 1320-- first entry in the chain (last exit statement in the loop). The 1321-- entries are chained through the Next_Exit_Statement field of the 1322-- N_Exit_Statement node with Empty marking the end of the list. 1323 1324-- First_Formal (synthesized) 1325-- Applies to subprograms and subprogram types, and also to entries 1326-- and entry families. Returns first formal of the subprogram or entry. 1327-- The formals are the first entities declared in a subprogram or in 1328-- a subprogram type (the designated type of an Access_To_Subprogram 1329-- definition) or in an entry. 1330 1331-- First_Formal_With_Extras (synthesized) 1332-- Applies to subprograms and subprogram types, and also in entries 1333-- and entry families. Returns first formal of the subprogram or entry. 1334-- Returns Empty if there are no formals. The list returned includes 1335-- all the extra formals (see description of Extra_Formals field). 1336 1337-- First_Index (Node17) 1338-- Defined in array types and subtypes. By introducing implicit subtypes 1339-- for the index constraints, we have the same structure for constrained 1340-- and unconstrained arrays, subtype marks and discrete ranges are 1341-- both represented by a subtype. This function returns the tree node 1342-- corresponding to an occurrence of the first index (NOT the entity for 1343-- the type). Subsequent indices are obtained using Next_Index. Note that 1344-- this field is defined for the case of string literal subtypes, but is 1345-- always Empty. 1346 1347-- First_Literal (Node17) 1348-- Defined in all enumeration types, including character and boolean 1349-- types. This field points to the first enumeration literal entity 1350-- for the type (i.e. it is set to First (Literals (N)) where N is 1351-- the enumeration type definition node. A special case occurs with 1352-- standard character and wide character types, where this field is 1353-- Empty, since there are no enumeration literal lists in these cases. 1354-- Note that this field is set in enumeration subtypes, but it still 1355-- points to the first literal of the base type in this case. 1356 1357-- First_Private_Entity (Node16) 1358-- Defined in all entities containing private parts (packages, protected 1359-- types and subtypes, task types and subtypes). The entities on the 1360-- entity chain are in order of declaration, so the entries for private 1361-- entities are at the end of the chain. This field points to the first 1362-- entity for the private part. It is Empty if there are no entities 1363-- declared in the private part or if there is no private part. 1364 1365-- First_Rep_Item (Node6) 1366-- Defined in all entities. If non-empty, points to a linked list of 1367-- representation pragmas nodes and representation clause nodes that 1368-- apply to the entity, linked using Next_Rep_Item, with Empty marking 1369-- the end of the list. In the case of derived types and subtypes, the 1370-- new entity inherits the chain at the point of declaration. This means 1371-- that it is possible to have multiple instances of the same kind of rep 1372-- item on the chain, in which case it is the first one that applies to 1373-- the entity. 1374-- 1375-- Note: pragmas that can apply to more than one overloadable entity, 1376-- (Convention, Interface, Inline, Inline_Always, Import, Export, 1377-- External) are never present on this chain when they apply to 1378-- overloadable entities, since it is impossible for a given pragma 1379-- to be on more than one chain at a time. 1380-- 1381-- For most representation items, the representation information is 1382-- reflected in other fields and flags in the entity. For example if a 1383-- record representation clause is present, the component entities 1384-- reflect the specified information. However, there are some items that 1385-- are only reflected in the chain. These include: 1386-- 1387-- Machine_Attribute pragma 1388-- Link_Alias pragma 1389-- Linker_Constructor pragma 1390-- Linker_Destructor pragma 1391-- Weak_External pragma 1392-- Thread_Local_Storage pragma 1393-- 1394-- If any of these items are present, then the flag Has_Gigi_Rep_Item is 1395-- set, indicating that the backend should search the chain. 1396-- 1397-- Other representation items are included in the chain so that error 1398-- messages can easily locate the relevant nodes for posting errors. 1399-- Note in particular that size clauses are defined only for this 1400-- purpose, and should only be accessed if Has_Size_Clause is set. 1401 1402-- Float_Rep (Uint10) 1403-- Defined in floating-point entities. Contains a value of type 1404-- Float_Rep_Kind. Together with the Digits_Value uniquely defines 1405-- the floating-point representation to be used. 1406 1407-- Freeze_Node (Node7) 1408-- Defined in all entities. If there is an associated freeze node for the 1409-- entity, this field references this freeze node. If no freeze node is 1410-- associated with the entity, then this field is Empty. See package 1411-- Freeze for further details. 1412 1413-- From_Limited_With (Flag159) 1414-- Defined in abtract states, package and type entities. Set to True when 1415-- the related entity is generated by the expansion of a limited with 1416-- clause. Such an entity is said to be a "shadow" - it acts as the 1417-- abstract view of a state or variable or as the incomplete view of a 1418-- type by inheriting relevant attributes from the said entity. 1419 1420-- Full_View (Node11) 1421-- Defined in all type and subtype entities and in deferred constants. 1422-- References the entity for the corresponding full type or constant 1423-- declaration. For all types other than private and incomplete types, 1424-- this field always contains Empty. If an incomplete type E1 is 1425-- completed by a private type E2 whose full type declaration entity is 1426-- E3 then the full view of E1 is E2, and the full view of E2 is E3. See 1427-- also Underlying_Type. 1428 1429-- Generic_Homonym (Node11) 1430-- Defined in generic packages. The generic homonym is the entity of 1431-- a renaming declaration inserted in every generic unit. It is used 1432-- to resolve the name of a local entity that is given by a qualified 1433-- name, when the generic entity itself is hidden by a local name. 1434 1435-- Generic_Renamings (Elist23) 1436-- Defined in package and subprogram instances. Holds mapping that 1437-- associates generic parameters with the corresponding instances, in 1438-- those cases where the instance is an entity. 1439 1440-- Handler_Records (List10) 1441-- Defined in subprogram and package entities. Points to a list of 1442-- identifiers referencing the handler record entities for the 1443-- corresponding unit. 1444 1445-- Has_Aliased_Components (Flag135) [implementation base type only] 1446-- Defined in array type entities. Indicates that the component type 1447-- of the array is aliased. Should this also be set for records to 1448-- indicate that at least one component is aliased (see processing in 1449-- Sem_Prag.Process_Atomic_Independent_Shared_Volatile???) 1450 1451-- Has_Alignment_Clause (Flag46) 1452-- Defined in all type entities and objects. Indicates if an alignment 1453-- clause has been given for the entity. If set, then Alignment_Clause 1454-- returns the N_Attribute_Definition node for the alignment attribute 1455-- definition clause. Note that it is possible for this flag to be False 1456-- even when Alignment_Clause returns non_Empty (this happens in the case 1457-- of derived type declarations). 1458 1459-- Has_All_Calls_Remote (Flag79) 1460-- Defined in all library unit entities. Set if the library unit has an 1461-- All_Calls_Remote pragma. Note that such entities must also be RCI 1462-- entities, so the flag Is_Remote_Call_Interface will always be set if 1463-- this flag is set. 1464 1465-- Has_Atomic_Components (Flag86) [implementation base type only] 1466-- Defined in all types and objects. Set only for an array type or 1467-- an array object if a valid pragma Atomic_Components applies to the 1468-- type or object. Note that in the case of an object, this flag is 1469-- only set on the object if there was an explicit pragma for the 1470-- object. In other words, the proper test for whether an object has 1471-- atomic components is to see if either the object or its base type 1472-- has this flag set. Note that in the case of a type, the pragma will 1473-- be chained to the rep item chain of the first subtype in the usual 1474-- manner. 1475 1476-- Has_Attach_Handler (synthesized) 1477-- Applies to record types that are constructed by the expander to 1478-- represent protected types. Returns True if there is at least one 1479-- Attach_Handler pragma in the corresponding specification. 1480 1481-- Has_Biased_Representation (Flag139) 1482-- Defined in discrete types (where it applies to the type'size value), 1483-- and to objects (both stand-alone and components), where it applies to 1484-- the size of the object from a size or record component clause. In 1485-- all cases it indicates that the size in question is smaller than 1486-- would normally be required, but that the size requirement can be 1487-- satisfied by using a biased representation, in which stored values 1488-- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to 1489-- reduce the required size. For example, a type with a range of 1..2 1490-- takes one bit, using 0 to represent 1 and 1 to represent 2. 1491-- 1492-- Note that in the object and component cases, the flag is only set if 1493-- the type is unbiased, but the object specifies a smaller size than the 1494-- size of the type, forcing biased representation for the object, but 1495-- the subtype is still an unbiased type. 1496 1497-- Has_Completion (Flag26) 1498-- Defined in all entities that require a completion (functions, 1499-- procedures, private types, limited private types, incomplete types, 1500-- constants and packages that require a body). The flag is set if the 1501-- completion has been encountered and analyzed. 1502 1503-- Has_Completion_In_Body (Flag71) 1504-- Defined in all entities for types and subtypes. Set only in "Taft 1505-- amendment types" (incomplete types whose full declaration appears in 1506-- the package body). 1507 1508-- Has_Complex_Representation (Flag140) [implementation base type only] 1509-- Defined in all type entities. Set only for a record base type to 1510-- which a valid pragma Complex_Representation applies. 1511 1512-- Has_Component_Size_Clause (Flag68) [implementation base type only] 1513-- Defined in all type entities. Set if a component size clause is 1514-- Defined for the given type. Note that this flag can be False even 1515-- if Component_Size is non-zero (happens in the case of derived types). 1516 1517-- Has_Constrained_Partial_View (Flag187) 1518-- Defined in private type and their completions, when the private 1519-- type has no discriminants and the full view has discriminants with 1520-- defaults. In Ada 2005 heap-allocated objects of such types are not 1521-- constrained, and can change their discriminants with full assignment. 1522-- 1523-- Ada 2012 has an additional rule (3.3. (23/10.3)) concerning objects 1524-- declared in a generic package body. Objects whose type is an untagged 1525-- generic formal private type are considered to have a constrained 1526-- partial view. The predicate Object_Type_Has_Constrained_Partial_View 1527-- in sem_aux is used to test for this case. 1528 1529-- Has_Contiguous_Rep (Flag181) 1530-- Defined in enumeration types. Set if the type as a representation 1531-- clause whose entries are successive integers. 1532 1533-- Has_Controlled_Component (Flag43) [base type only] 1534-- Defined in all type and subtype entities. Set only for composite type 1535-- entities which contain a component that either is a controlled type, 1536-- or itself contains controlled component (i.e. either Is_Controlled or 1537-- Has_Controlled_Component is set for at least one component). 1538 1539-- Has_Controlling_Result (Flag98) 1540-- Defined in E_Function entities. Set if the function is a primitive 1541-- function of a tagged type which can dispatch on result. 1542 1543-- Has_Convention_Pragma (Flag119) 1544-- Defined in all entities. Set for an entity for which a valid pragma 1545-- Convention, Import, or Export has been given. Used to prevent more 1546-- than one such pragma appearing for a given entity (RM B.1(45)). 1547 1548-- Has_Default_Aspect (Flag39) [base type only] 1549-- Defined in entities for types and subtypes, set for scalar types with 1550-- a Default_Value aspect and array types with a Default_Component_Value 1551-- aspect. If this flag is set, then a corresponding aspect specification 1552-- node will be present on the rep item chain for the entity. For a 1553-- derived type that inherits a default from its ancestor, the default 1554-- value is set, but it may be overridden by an aspect declaration on 1555-- type derivation. 1556 1557-- Has_Default_Init_Cond (Flag3) [base type only] 1558-- Defined in all type entities. Set if pragma Default_Initial_Condition 1559-- applies to a private type and by extension to its full view. This flag 1560-- is mutually exclusive with flag Has_Inherited_Default_Init_Cond. 1561 1562-- Has_Delayed_Aspects (Flag200) 1563-- Defined in all entities. Set if the Rep_Item chain for the entity has 1564-- one or more N_Aspect_Definition nodes chained which are not to be 1565-- evaluated till the freeze point. The aspect definition expression 1566-- clause has been preanalyzed to get visibility at the point of use, 1567-- but no other action has been taken. 1568 1569-- Has_Delayed_Freeze (Flag18) 1570-- Defined in all entities. Set to indicate that an explicit freeze 1571-- node must be generated for the entity at its freezing point. See 1572-- separate section ("Delayed Freezing and Elaboration") for details. 1573 1574-- Has_Delayed_Rep_Aspects (Flag261) 1575-- Defined in all types and subtypes. This flag is set if there is at 1576-- least one aspect for a representation characteristic that has to be 1577-- delayed and is one of the characteristics that may be inherited by 1578-- types derived from this type if not overridden. If this flag is set, 1579-- then types derived from this type have May_Inherit_Delayed_Rep_Aspects 1580-- set, signalling that Freeze.Inherit_Delayed_Rep_Aspects must be called 1581-- at the freeze point of the derived type. 1582 1583-- Has_Discriminants (Flag5) 1584-- Defined in all types and subtypes. For types that are allowed to have 1585-- discriminants (record types and subtypes, task types and subtypes, 1586-- protected types and subtypes, private types, limited private types, 1587-- and incomplete types), indicates if the corresponding type or subtype 1588-- has a known discriminant part. Always false for all other types. 1589 1590-- Has_Dispatch_Table (Flag220) 1591-- Defined in E_Record_Types that are tagged. Set to indicate that the 1592-- corresponding dispatch table is already built. This flag is used to 1593-- avoid duplicate construction of library level dispatch tables (because 1594-- the declaration of library level objects cause premature construction 1595-- of the table); otherwise the code that builds the table is added at 1596-- the end of the list of declarations of the package. 1597 1598-- Has_Dynamic_Predicate_Aspect (Flag258) 1599-- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect 1600-- was explicitly applied to the type. Generally we treat predicates as 1601-- static if possible, regardless of whether they are specified using 1602-- Predicate, Static_Predicate, or Dynamic_Predicate. And if a predicate 1603-- can be treated as static (i.e. its expression is predicate-static), 1604-- then the flag Has_Static_Predicate will be set True. But there are 1605-- cases where legality is affected by the presence of an explicit 1606-- Dynamic_Predicate aspect. For example, even if a predicate looks 1607-- static, you can't use it in a case statement if there is an explicit 1608-- Dynamic_Predicate aspect specified. So test Has_Static_Predicate if 1609-- you just want to know if the predicate can be evaluated statically, 1610-- but test Has_Dynamic_Predicate_Aspect to enforce legality rules about 1611-- the use of dynamic predicates. 1612 1613-- Has_Entries (synthesized) 1614-- Applies to concurrent types. True if any entries are declared 1615-- within the task or protected definition for the type. 1616 1617-- Has_Enumeration_Rep_Clause (Flag66) 1618-- Defined in enumeration types. Set if an enumeration representation 1619-- clause has been given for this enumeration type. Used to prevent more 1620-- than one enumeration representation clause for a given type. Note 1621-- that this does not imply a representation with holes, since the rep 1622-- clause may merely confirm the default 0..N representation. 1623 1624-- Has_Exit (Flag47) 1625-- Defined in loop entities. Set if the loop contains an exit statement. 1626 1627-- Has_Expanded_Contract (Flag240) 1628-- Defined in functions, procedures, entries, and entry families. Set 1629-- when a subprogram has a N_Contract node that has been expanded. The 1630-- flag prevents double expansion of a contract when a construct is 1631-- rewritten into something else and subsequently reanalyzed/expanded. 1632 1633-- Has_Foreign_Convention (synthesized) 1634-- Applies to all entities. Determines if the Convention for the 1635-- entity is a foreign convention (i.e. is other than Convention_Ada, 1636-- Convention_Intrinsic, Convention_Entry or Convention_Protected). 1637 1638-- Has_Forward_Instantiation (Flag175) 1639-- Defined in package entities. Set for packages that instantiate local 1640-- generic entities before the corresponding generic body has been seen. 1641-- If a package has a forward instantiation, we cannot inline subprograms 1642-- appearing in the same package because the placement requirements of 1643-- the instance will conflict with the linear elaboration of front-end 1644-- inlining. 1645 1646-- Has_Fully_Qualified_Name (Flag173) 1647-- Defined in all entities. Set if the name in the Chars field has been 1648-- replaced by the fully qualified name, as used for debug output. See 1649-- Exp_Dbug for a full description of the use of this flag and also the 1650-- related flag Has_Qualified_Name. 1651 1652-- Has_Gigi_Rep_Item (Flag82) 1653-- Defined in all entities. Set if the rep item chain (referenced by 1654-- First_Rep_Item and linked through the Next_Rep_Item chain) contains a 1655-- representation item that needs to be specially processed by the back 1656-- end, i.e. one of the following items: 1657-- 1658-- Machine_Attribute pragma 1659-- Linker_Alias pragma 1660-- Linker_Constructor pragma 1661-- Linker_Destructor pragma 1662-- Weak_External pragma 1663-- Thread_Local_Storage pragma 1664-- 1665-- If this flag is set, then the backend should scan the rep item chain 1666-- to process any of these items that appear. At least one such item will 1667-- be present. 1668-- 1669-- Has_Homonym (Flag56) 1670-- Defined in all entities. Set if an entity has a homonym in the same 1671-- scope. Used by the backend to generate unique names for all entities. 1672 1673-- Has_Implicit_Dereference (Flag251) 1674-- Defined in types and discriminants. Set if the type has an aspect 1675-- Implicit_Dereference. Set also on the discriminant named in the aspect 1676-- clause, to simplify type resolution. 1677 1678-- Has_Independent_Components (Flag34) [implementation base type only] 1679-- Defined in all types and objects. Set only for a record type or an 1680-- array type or array object if a valid pragma Independent_Components 1681-- applies to the type or object. Note that in the case of an object, 1682-- this flag is only set on the object if there was an explicit pragma 1683-- for the object. In other words, the proper test for whether an object 1684-- has independent components is to see if either the object or its base 1685-- type has this flag set. Note that in the case of a type, the pragma 1686-- will be chained to the rep item chain of the first subtype in the 1687-- usual manner. 1688 1689-- Has_Inheritable_Invariants (Flag248) 1690-- Defined in all type entities. Set in private types from which one 1691-- or more Invariant'Class aspects will be inherited if a another type is 1692-- derived from the type (i.e. those types which have an Invariant'Class 1693-- aspect, or which inherit one or more Invariant'Class aspects). Also 1694-- set in the corresponding full types. Note that it might be the full 1695-- type which has inheritable invariants, and in this case the flag will 1696-- also be set in the private type. 1697 1698-- Has_Inherited_Default_Init_Cond (Flag133) [base type only] 1699-- Defined in all type entities. Set when a derived type inherits pragma 1700-- Default_Initial_Condition from its parent type. This flag is mutually 1701-- exclusive with flag Has_Default_Init_Cond. 1702 1703-- Has_Initial_Value (Flag219) 1704-- Defined in entities for variables and out parameters. Set if there 1705-- is an explicit initial value expression in the declaration of the 1706-- variable. Note that this is set only if this initial value is 1707-- explicit, it is not set for the case of implicit initialization 1708-- of access types or controlled types. Always set to False for out 1709-- parameters. Also defined in entities for in and in-out parameters, 1710-- but always false in these cases. 1711 1712-- Has_Interrupt_Handler (synthesized) 1713-- Applies to all protected type entities. Set if the protected type 1714-- definition contains at least one procedure to which a pragma 1715-- Interrupt_Handler applies. 1716 1717-- Has_Invariants (Flag232) 1718-- Defined in all type entities and in subprogram entities. Set in 1719-- private types if an Invariant or Invariant'Class aspect applies to the 1720-- type, or if the type inherits one or more Invariant'Class aspects. 1721-- Also set in the corresponding full type. Note: if this flag is set 1722-- True, then usually the Invariant_Procedure attribute is set once the 1723-- type is frozen, however this may not be true in some error situations. 1724-- Note that it might be the full type which has inheritable invariants, 1725-- and then the flag will also be set in the private type. 1726 1727-- Has_Loop_Entry_Attributes (Flag260) 1728-- Defined in E_Loop entities. Set when the loop is subject to at least 1729-- one attribute 'Loop_Entry. The flag also implies that the loop has 1730-- already been transformed. See Expand_Loop_Entry_Attribute for details. 1731 1732-- Has_Machine_Radix_Clause (Flag83) 1733-- Defined in decimal types and subtypes, set if a Machine_Radix 1734-- representation clause is present. This flag is used to detect 1735-- the error of multiple machine radix clauses for a single type. 1736 1737-- Has_Master_Entity (Flag21) 1738-- Defined in entities that can appear in the scope stack (see spec 1739-- of Sem). It is set if a task master entity (_master) has been 1740-- declared and initialized in the corresponding scope. 1741 1742-- Has_Missing_Return (Flag142) 1743-- Defined in functions and generic functions. Set if there is one or 1744-- more missing return statements in the function. This is used to 1745-- control wrapping of the body in Exp_Ch6 to ensure that the program 1746-- error exception is correctly raised in this case at runtime. 1747 1748-- Has_Nested_Block_With_Handler (Flag101) 1749-- Defined in scope entities. Set if there is a nested block within the 1750-- scope that has an exception handler and the two scopes are in the 1751-- same procedure. This is used by the backend for controlling certain 1752-- optimizations to ensure that they are consistent with exceptions. 1753-- See documentation in backend for further details. 1754 1755-- Has_Nested_Subprogram (Flag282) 1756-- Defined in subprogram entities. Set for a subprogram which contains at 1757-- least one nested subprogram. 1758 1759-- Has_Non_Limited_View (synth) 1760-- Defined in E_Incomplete_Type, E_Incomplete_Subtype, E_Class_Wide_Type, 1761-- E_Abstract_State entities. True if their Non_Limited_View attribute 1762-- is present. 1763 1764-- Has_Non_Null_Visible_Refinement (synth) 1765-- Defined in E_Abstract_State entities. True if the state has a visible 1766-- refinement of at least one variable or state constituent as expressed 1767-- in aspect/pragma Refined_State. 1768 1769-- Has_Non_Standard_Rep (Flag75) [implementation base type only] 1770-- Defined in all type entities. Set when some representation clause 1771-- or pragma causes the representation of the item to be significantly 1772-- modified. In this category are changes of small or radix for a 1773-- fixed-point type, change of component size for an array, and record 1774-- or enumeration representation clauses, as well as packed pragmas. 1775-- All other representation clauses (e.g. Size and Alignment clauses) 1776-- are not considered to be significant since they do not affect 1777-- stored bit patterns. 1778 1779-- Has_Null_Abstract_State (synth) 1780-- Defined in package entities. True if the package is subject to a null 1781-- Abstract_State aspect/pragma. 1782 1783-- Has_Null_Visible_Refinement (synth) 1784-- Defined in E_Abstract_State entities. True if the state has a visible 1785-- null refinement as expressed in aspect/pragma Refined_State. 1786 1787-- Has_Object_Size_Clause (Flag172) 1788-- Defined in entities for types and subtypes. Set if an Object_Size 1789-- clause has been processed for the type Used to prevent multiple 1790-- Object_Size clauses for a given entity. 1791 1792-- Has_Out_Or_In_Out_Parameter (Flag110) 1793-- Present in subprograms, generic subprograms, entries, and entry 1794-- families. Set if they have at least one OUT or IN OUT parameter 1795-- (allowed for functions only in Ada 2012). 1796 1797-- Has_Per_Object_Constraint (Flag154) 1798-- Defined in E_Component entities. Set if the subtype of the component 1799-- has a per object constraint. Per object constraints result from the 1800-- following situations : 1801-- 1802-- 1. N_Attribute_Reference - when the prefix is the enclosing type and 1803-- the attribute is Access. 1804-- 2. N_Discriminant_Association - when the expression uses the 1805-- discriminant of the enclosing type. 1806-- 3. N_Index_Or_Discriminant_Constraint - when at least one of the 1807-- individual constraints is a per object constraint. 1808-- 4. N_Range - when the lower or upper bound uses the discriminant of 1809-- the enclosing type. 1810-- 5. N_Range_Constraint - when the range expression uses the 1811-- discriminant of the enclosing type. 1812 1813-- Has_Pragma_Controlled (Flag27) [implementation base type only] 1814-- Defined in access type entities. It is set if a pragma Controlled 1815-- applies to the access type. 1816 1817-- Has_Pragma_Elaborate_Body (Flag150) 1818-- Defined in all entities. Set in compilation unit entities if a 1819-- pragma Elaborate_Body applies to the compilation unit. 1820 1821-- Has_Pragma_Inline (Flag157) 1822-- Defined in all entities. Set for functions and procedures for which a 1823-- pragma Inline or Inline_Always applies to the subprogram. Note that 1824-- this flag can be set even if Is_Inlined is not set. This happens for 1825-- pragma Inline (if Inline_Active is False). In other words, the flag 1826-- Has_Pragma_Inline represents the formal semantic status, and is used 1827-- for checking semantic correctness. The flag Is_Inlined indicates 1828-- whether inlining is actually active for the entity. 1829 1830-- Has_Pragma_Inline_Always (Flag230) 1831-- Defined in all entities. Set for functions and procedures for which a 1832-- pragma Inline_Always applies. Note that if this flag is set, the flag 1833-- Has_Pragma_Inline is also set. 1834 1835-- Has_Pragma_No_Inline (Flag201) 1836-- Defined in all entities. Set for functions and procedures for which a 1837-- pragma No_Inline applies. Note that if this flag is set, the flag 1838-- Has_Pragma_Inline_Always cannot be set. 1839 1840-- Has_Pragma_Ordered (Flag198) [implementation base type only] 1841-- Defined in entities for enumeration types. If set indicates that a 1842-- valid pragma Ordered was given for the type. This flag is inherited 1843-- by derived enumeration types. We don't need to distinguish the derived 1844-- case since we allow multiple occurrences of this pragma anyway. 1845 1846-- Has_Pragma_Pack (Flag121) [implementation base type only] 1847-- Defined in array and record type entities. If set, indicates that a 1848-- valid pragma Pack was given for the type. Note that this flag is not 1849-- inherited by derived type. See also the Is_Packed flag. 1850 1851-- Has_Pragma_Preelab_Init (Flag221) 1852-- Defined in type and subtype entities. If set indicates that a valid 1853-- pragma Preelaborable_Initialization applies to the type. 1854 1855-- Has_Pragma_Pure (Flag203) 1856-- Defined in all entities. If set, indicates that a valid pragma Pure 1857-- was given for the entity. In some cases, we need to test whether 1858-- Is_Pure was explicitly set using this pragma. 1859 1860-- Has_Pragma_Pure_Function (Flag179) 1861-- Defined in all entities. If set, indicates that a valid pragma 1862-- Pure_Function was given for the entity. In some cases, we need to test 1863-- whether Is_Pure was explicitly set using this pragma. We also set 1864-- this flag for some internal entities that we know should be treated 1865-- as pure for optimization purposes. 1866 1867-- Has_Pragma_Thread_Local_Storage (Flag169) 1868-- Defined in all entities. If set, indicates that a valid pragma 1869-- Thread_Local_Storage was given for the entity. 1870 1871-- Has_Pragma_Unmodified (Flag233) 1872-- Defined in all entities. Can only be set for variables (E_Variable, 1873-- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified 1874-- applies to the variable, indicating that no warning should be given 1875-- if the entity is never modified. Note that clients should generally 1876-- not test this flag directly, but instead use function Has_Unmodified. 1877 1878-- Has_Pragma_Unreferenced (Flag180) 1879-- Defined in all entities. Set if a valid pragma Unreferenced applies 1880-- to the entity, indicating that no warning should be given if the 1881-- entity has no references, but a warning should be given if it is 1882-- in fact referenced. For private types, this flag is set in both the 1883-- private entity and full entity if the pragma applies to either. Note 1884-- that clients should generally not test this flag directly, but instead 1885-- use function Has_Unreferenced. 1886 1887-- Has_Pragma_Unreferenced_Objects (Flag212) 1888-- Defined in type and subtype entities. Set if a valid pragma 1889-- Unreferenced_Objects applies to the type, indicating that no warning 1890-- should be given for objects of such a type for being unreferenced 1891-- (but unlike the case with pragma Unreferenced, it is ok to reference 1892-- such an object and no warning is generated. 1893 1894-- Has_Predicates (Flag250) 1895-- Defined in type and subtype entities. Set if a pragma Predicate or 1896-- Predicate aspect applies to the type or subtype, or if it inherits a 1897-- Predicate aspect from its parent or progenitor types. 1898 1899-- Has_Primitive_Operations (Flag120) [base type only] 1900-- Defined in all type entities. Set if at least one primitive operation 1901-- is defined for the type. 1902 1903-- Has_Private_Ancestor (Flag151) 1904-- Applies to type extensions. True if some ancestor is derived from a 1905-- private type, making some components invisible and aggregates illegal. 1906-- This flag is set at the point of derivation. The legality of the 1907-- aggregate must be rechecked because it also depends on the visibility 1908-- at the point the aggregate is resolved. See sem_aggr.adb. This is part 1909-- of AI05-0115. 1910 1911-- Has_Private_Declaration (Flag155) 1912-- Defined in all entities. Set if it is the defining entity of a private 1913-- type declaration or its corresponding full declaration. This flag is 1914-- thus preserved when the full and the partial views are exchanged, to 1915-- indicate if a full type declaration is a completion. Used for semantic 1916-- checks in E.4(18) and elsewhere. 1917 1918-- Has_Protected (Flag271) [base type only] 1919-- Defined in all type entities. Set on protected types themselves, and 1920-- also (recursively) on any composite type which has a component for 1921-- which Has_Protected is set. The meaning is that an allocator for 1922-- or declaration of such an object must create the required protected 1923-- objects. Note: the flag is not set on access types, even if they 1924-- designate an object that Has_Protected. 1925 1926-- Has_Qualified_Name (Flag161) 1927-- Defined in all entities. Set if the name in the Chars field has 1928-- been replaced by its qualified name, as used for debug output. See 1929-- Exp_Dbug for a full description of qualification requirements. For 1930-- some entities, the name is the fully qualified name, but there are 1931-- exceptions. In particular, for local variables in procedures, we 1932-- do not include the procedure itself or higher scopes. See also the 1933-- flag Has_Fully_Qualified_Name, which is set if the name does indeed 1934-- include the fully qualified name. 1935 1936-- Has_RACW (Flag214) 1937-- Defined in package spec entities. Set if the spec contains the 1938-- declaration of a remote access-to-classwide type. 1939 1940-- Has_Record_Rep_Clause (Flag65) [implementation base type only] 1941-- Defined in record types. Set if a record representation clause has 1942-- been given for this record type. Used to prevent more than one such 1943-- clause for a given record type. Note that this is initially cleared 1944-- for a derived type, even though the representation is inherited. See 1945-- also the flag Has_Specified_Layout. 1946 1947-- Has_Recursive_Call (Flag143) 1948-- Defined in procedures. Set if a direct parameterless recursive call 1949-- is detected while analyzing the body. Used to activate some error 1950-- checks for infinite recursion. 1951 1952-- Has_Shift_Operator (Flag267) [base type only] 1953-- Defined in integer types. Set in the base type of an integer type for 1954-- which at least one of the shift operators is defined. 1955 1956-- Has_Size_Clause (Flag29) 1957-- Defined in entities for types and objects. Set if a size clause is 1958-- defined for the entity. Used to prevent multiple Size clauses for a 1959-- given entity. Note that it is always initially cleared for a derived 1960-- type, even though the Size for such a type is inherited from a Size 1961-- clause given for the parent type. 1962 1963-- Has_Small_Clause (Flag67) 1964-- Defined in ordinary fixed point types (but not subtypes). Indicates 1965-- that a small clause has been given for the entity. Used to prevent 1966-- multiple Small clauses for a given entity. Note that it is always 1967-- initially cleared for a derived type, even though the Small for such 1968-- a type is inherited from a Small clause given for the parent type. 1969 1970-- Has_Specified_Layout (Flag100) [implementation base type only] 1971-- Defined in all type entities. Set for a record type or subtype if 1972-- the record layout has been specified by a record representation 1973-- clause. Note that this differs from the flag Has_Record_Rep_Clause 1974-- in that it is inherited by a derived type. Has_Record_Rep_Clause is 1975-- used to indicate that the type is mentioned explicitly in a record 1976-- representation clause, and thus is not inherited by a derived type. 1977-- This flag is always False for non-record types. 1978 1979-- Has_Specified_Stream_Input (Flag190) 1980-- Has_Specified_Stream_Output (Flag191) 1981-- Has_Specified_Stream_Read (Flag192) 1982-- Has_Specified_Stream_Write (Flag193) 1983-- Defined in all type and subtype entities. Set for a given view if the 1984-- corresponding stream-oriented attribute has been defined by an 1985-- attribute definition clause. When such a clause occurs, a TSS is set 1986-- on the underlying full view; the flags are used to track visibility of 1987-- the attribute definition clause for partial or incomplete views. 1988 1989-- Has_Static_Discriminants (Flag211) 1990-- Defined in record subtypes constrained by discriminant values. Set if 1991-- all the discriminant values have static values, meaning that in the 1992-- case of a variant record, the component list can be trimmed down to 1993-- include only the components corresponding to these discriminants. 1994 1995-- Has_Static_Predicate (Flag269) 1996-- Defined in all types and subtypes. Set if the type (which must be a 1997-- scalar type) has a predicate whose expression is predicate-static. 1998-- This can result from the use of any Predicate, Static_Predicate, or 1999-- Dynamic_Predicate aspect. We can distinguish these cases by testing 2000-- Has_Static_Predicate_Aspect and Has_Dynamic_Predicate_Aspect. See 2001-- description of the latter flag for further information on dynamic 2002-- predicates which are also static. 2003 2004-- Has_Static_Predicate_Aspect (Flag259) 2005-- Defined in all types and subtypes. Set if a Static_Predicate aspect 2006-- applies to the type. Note that we can tell if a static predicate is 2007-- present by looking at Has_Static_Predicate, but this could have come 2008-- from a Predicate aspect or pragma or even from a Dynamic_Predicate 2009-- aspect. When we need to know the difference (e.g. to know what set of 2010-- check policies apply, use this flag and Has_Dynamic_Predicate_Aspect 2011-- to determine which case we have). 2012 2013-- Has_Storage_Size_Clause (Flag23) [implementation base type only] 2014-- Defined in task types and access types. It is set if a Storage_Size 2015-- clause is present for the type. Used to prevent multiple clauses for 2016-- one type. Note that this flag is initially cleared for a derived type 2017-- even though the Storage_Size for such a type is inherited from a 2018-- Storage_Size clause given for the parent type. Note that in the case 2019-- of access types, this flag is defined only in the root type, since a 2020-- storage size clause cannot be given to a derived type. 2021 2022-- Has_Stream_Size_Clause (Flag184) 2023-- Defined in all entities. It is set for types which have a Stream_Size 2024-- clause attribute. Used to prevent multiple Stream_Size clauses for a 2025-- given entity, and also whether it is necessary to check for a stream 2026-- size clause. 2027 2028-- Has_Task (Flag30) [base type only] 2029-- Defined in all type entities. Set on task types themselves, and also 2030-- (recursively) on any composite type which has a component for which 2031-- Has_Task is set. The meaning is that an allocator or declaration of 2032-- such an object must create the required tasks. Note: the flag is not 2033-- set on access types, even if they designate an object that Has_Task. 2034 2035-- Has_Thunks (Flag228) 2036-- Applies to E_Constant entities marked Is_Tag. True for secondary tag 2037-- referencing a dispatch table whose contents are pointers to thunks. 2038 2039-- Has_Unchecked_Union (Flag123) [base type only] 2040-- Defined in all type entities. Set on unchecked unions themselves 2041-- and (recursively) on any composite type which has a component for 2042-- which Has_Unchecked_Union is set. The meaning is that a comparison 2043-- operation or 'Valid_Scalars reference for the type is not permitted. 2044-- Note that the flag is not set on access types, even if they designate 2045-- an object that has the flag Has_Unchecked_Union set. 2046 2047-- Has_Unknown_Discriminants (Flag72) 2048-- Defined in all entities. Set for types with unknown discriminants. 2049-- Types can have unknown discriminants either from their declaration or 2050-- through type derivation. The use of this flag exactly meets the spec 2051-- in RM 3.7(26). Note that all class-wide types are considered to have 2052-- unknown discriminants. Note that both flags Has_Discriminants and 2053-- Has_Unknown_Discriminants may be true for a type. Class-wide types and 2054-- their subtypes have unknown discriminants and can have declared ones 2055-- as well. Private types declared with unknown discriminants may have a 2056-- full view that has explicit discriminants, and both flag will be set 2057-- on the partial view, to ensure that discriminants are properly 2058-- inherited in certain contexts. 2059 2060-- Has_Visible_Refinement (Flag263) 2061-- Defined in E_Abstract_State entities. Set when a state has at least 2062-- one refinement constituent and analysis is in the region between 2063-- pragma Refined_State and the end of the package body declarations. 2064 2065-- Has_Volatile_Components (Flag87) [implementation base type only] 2066-- Defined in all types and objects. Set only for an array type or array 2067-- object if a valid pragma Volatile_Components or a valid pragma 2068-- Atomic_Components applies to the type or object. Note that in the case 2069-- of an object, this flag is only set on the object if there was an 2070-- explicit pragma for the object. In other words, the proper test for 2071-- whether an object has volatile components is to see if either the 2072-- object or its base type has this flag set. Note that in the case of a 2073-- type the pragma will be chained to the rep item chain of the first 2074-- subtype in the usual manner. 2075 2076-- Has_Xref_Entry (Flag182) 2077-- Defined in all entities. Set if an entity has an entry in the Xref 2078-- information generated in ali files. This is true for all source 2079-- entities in the extended main source file. It is also true of entities 2080-- in other packages that are referenced directly or indirectly from the 2081-- main source file (indirect reference occurs when the main source file 2082-- references an entity with a type reference. See package Lib.Xref for 2083-- further details). 2084 2085-- Hiding_Loop_Variable (Node8) 2086-- Defined in variables. Set only if a variable of a discrete type is 2087-- hidden by a loop variable in the same local scope, in which case 2088-- the Hiding_Loop_Variable field of the hidden variable points to 2089-- the E_Loop_Parameter entity doing the hiding. Used in processing 2090-- warning messages if the hidden variable turns out to be unused 2091-- or is referenced without being set. 2092 2093-- Homonym (Node4) 2094-- Defined in all entities. Link for list of entities that have the 2095-- same source name and that are declared in the same or enclosing 2096-- scopes. Homonyms in the same scope are overloaded. Used for name 2097-- resolution and for the generation of debugging information. 2098 2099-- Implementation_Base_Type (synthesized) 2100-- Applies to all entities. For types, similar to Base_Type, but never 2101-- returns a private type when applied to a non-private type. Instead in 2102-- this case, it always returns the Underlying_Type of the base type, so 2103-- that we still have a concrete type. For entities other than types, 2104-- returns the entity unchanged. 2105 2106-- Import_Pragma (Node35) 2107-- Defined in subprogram entities. Set if a valid pragma Import or pragma 2108-- Import_Function or pragma Import_Procedure applies to the subprogram, 2109-- in which case this field points to the pragma (we can't use the normal 2110-- Rep_Item chain mechanism, because a single pragma Import can apply 2111-- to multiple subprogram entities). 2112 2113-- Incomplete_Actuals (Elist24) 2114-- Defined on package entities that are instances. Indicates the actuals 2115-- types in the instantiation that are limited views. If this list is 2116-- not empty, the instantiation, which appears in a package declaration, 2117-- is relocated to the corresponding package body, which must have a 2118-- corresponding nonlimited with_clause. 2119 2120-- In_Package_Body (Flag48) 2121-- Defined in package entities. Set on the entity that denotes the 2122-- package (the defining occurrence of the package declaration) while 2123-- analyzing and expanding the package body. Reset on completion of 2124-- analysis/expansion. 2125 2126-- In_Private_Part (Flag45) 2127-- Defined in all entities. Can be set only in package entities and 2128-- objects. For package entities, this flag is set to indicate that the 2129-- private part of the package is being analyzed. The flag is reset at 2130-- the end of the package declaration. For objects it indicates that the 2131-- declaration of the object occurs in the private part of a package. 2132 2133-- Initialization_Statements (Node28) 2134-- Defined in constants and variables. For a composite object initialized 2135-- initialized with an aggregate that has been converted to a sequence 2136-- of assignments, points to a block statement containing the 2137-- assignments. 2138 2139-- Inner_Instances (Elist23) 2140-- Defined in generic units. Contains element list of units that are 2141-- instantiated within the given generic. Used to diagnose circular 2142-- instantiations. 2143 2144-- Interface_Alias (Node25) 2145-- Defined in subprograms that cover a primitive operation of an abstract 2146-- interface type. Can be set only if the Is_Hidden flag is also set, 2147-- since such entities are always hidden. Points to its associated 2148-- interface subprogram. It is used to register the subprogram in 2149-- secondary dispatch table of the interface (Ada 2005: AI-251). 2150 2151-- Interface_Name (Node21) 2152-- Defined in constants, variables, exceptions, functions, procedures, 2153-- and packages. Set to Empty unless an export, import, or interface name 2154-- pragma has explicitly specified an external name, in which case it 2155-- references an N_String_Literal node for the specified external name. 2156-- Note that if this field is Empty, and Is_Imported or Is_Exported is 2157-- set, then the default interface name is the name of the entity, cased 2158-- in a manner that is appropriate to the system in use. Note that 2159-- Interface_Name is ignored if an address clause is present (since it 2160-- is meaningless in this case). 2161 2162-- Interfaces (Elist25) 2163-- Defined in record types and subtypes. List of abstract interfaces 2164-- implemented by a tagged type that are not already implemented by the 2165-- ancestors (Ada 2005: AI-251). 2166 2167-- Invariant_Procedure (synthesized) 2168-- Defined in types and subtypes. Set for private types if one or more 2169-- Invariant, or Invariant'Class, or inherited Invariant'Class aspects 2170-- apply to the type. Points to the entity for a procedure which checks 2171-- the invariant. This invariant procedure takes a single argument of the 2172-- given type, and returns if the invariant holds, or raises exception 2173-- Assertion_Error with an appropriate message if it does not hold. This 2174-- attribute is defined but always empty for private subtypes. This 2175-- attribute is also set for the corresponding full type. 2176-- 2177-- Note: the reason this is marked as a synthesized attribute is that the 2178-- way this is stored is as an element of the Subprograms_For_Type field. 2179 2180-- In_Use (Flag8) 2181-- Defined in packages and types. Set when analyzing a use clause for 2182-- the corresponding entity. Reset at end of corresponding declarative 2183-- part. The flag on a type is also used to determine the visibility of 2184-- the primitive operators of the type. 2185 2186-- Is_Abstract_Subprogram (Flag19) 2187-- Defined in all subprograms and entries. Set for abstract subprograms. 2188-- Always False for enumeration literals and entries. See also 2189-- Requires_Overriding. 2190 2191-- Is_Abstract_Type (Flag146) 2192-- Defined in all types. Set for abstract types. 2193 2194-- Is_Access_Constant (Flag69) 2195-- Defined in access types and subtypes. Indicates that the keyword 2196-- constant was present in the access type definition. 2197 2198-- Is_Access_Protected_Subprogram_Type (synthesized) 2199-- Applies to all types, true for named and anonymous access to 2200-- protected subprograms. 2201 2202-- Is_Access_Type (synthesized) 2203-- Applies to all entities, true for access types and subtypes 2204 2205-- Is_Ada_2005_Only (Flag185) 2206-- Defined in all entities, true if a valid pragma Ada_05 or Ada_2005 2207-- applies to the entity which specifically names the entity, indicating 2208-- that the entity is Ada 2005 only. Note that this flag is not set if 2209-- the entity is part of a unit compiled with the normal no-argument form 2210-- of pragma Ada_05 or Ada_2005. 2211 2212-- Is_Ada_2012_Only (Flag199) 2213-- Defined in all entities, true if a valid pragma Ada_12 or Ada_2012 2214-- applies to the entity which specifically names the entity, indicating 2215-- that the entity is Ada 2012 only. Note that this flag is not set if 2216-- the entity is part of a unit compiled with the normal no-argument form 2217-- of pragma Ada_12 or Ada_2012. 2218 2219-- Is_Aliased (Flag15) 2220-- Defined in all entities. Set for objects and types whose declarations 2221-- carry the keyword aliased, and on record components that have the 2222-- keyword. For Ada 2012, also applies to formal parameters. 2223 2224-- Is_Array_Type (synthesized) 2225-- Applies to all entities, true for array types and subtypes 2226 2227-- Is_Asynchronous (Flag81) 2228-- Defined in all type entities and in procedure entities. Set 2229-- if a pragma Asynchronous applies to the entity. 2230 2231-- Is_Atomic (Flag85) 2232-- Defined in all type entities, and also in constants, components, and 2233-- variables. Set if a pragma Atomic or Shared applies to the entity. 2234-- In the case of private and incomplete types, this flag is set in 2235-- both the partial view and the full view. 2236 2237-- Is_Atomic_Or_VFA (synth) 2238-- Defined in all type entities, and also in constants, components and 2239-- variables. Set if a pragma Atomic or Shared or Volatile_Full_Access 2240-- applies to the entity. For many purposes VFA objects should be treated 2241-- the same as Atomic objects, and this predicate is intended for that 2242-- usage. In the case of private and incomplete types, the predicate 2243-- applies to both the partial view and the full view. 2244 2245-- Is_Base_Type (synthesized) 2246-- Applies to type and subtype entities. True if entity is a base type 2247 2248-- Is_Bit_Packed_Array (Flag122) [implementation base type only] 2249-- Defined in all entities. This flag is set for a packed array type that 2250-- is bit packed (i.e. the component size is known by the front end and 2251-- is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed is always set 2252-- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be 2253-- set without Is_Bit_Packed_Array for the case of an array having one or 2254-- more index types that are enumeration types with non-standard 2255-- enumeration representations. 2256 2257-- Is_Boolean_Type (synthesized) 2258-- Applies to all entities, true for boolean types and subtypes, 2259-- i.e. Standard.Boolean and all types ultimately derived from it. 2260 2261-- Is_Called (Flag102) 2262-- Defined in subprograms. Returns true if the subprogram is called 2263-- in the unit being compiled or in a unit in the context. Used for 2264-- inlining. 2265 2266-- Is_Character_Type (Flag63) 2267-- Defined in all entities. Set for character types and subtypes, 2268-- i.e. enumeration types that have at least one character literal. 2269 2270-- Is_Checked_Ghost_Entity (Flag277) 2271-- Applies to all entities. Set for abstract states, [generic] packages, 2272-- [generic] subprograms, components, discriminants, formal parameters, 2273-- objects, package bodies, subprogram bodies, and [sub]types subject to 2274-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2275-- subject to Assertion_Policy Ghost => Check. 2276 2277-- Is_Child_Unit (Flag73) 2278-- Defined in all entities. Set only for defining entities of program 2279-- units that are child units (but False for subunits). 2280 2281-- Is_Class_Wide_Equivalent_Type (Flag35) 2282-- Defined in record types and subtypes. Set to True, if the type acts 2283-- as a class-wide equivalent type, i.e. the Equivalent_Type field of 2284-- some class-wide subtype entity references this record type. 2285 2286-- Is_Class_Wide_Type (synthesized) 2287-- Applies to all entities, true for class wide types and subtypes 2288 2289-- Is_Compilation_Unit (Flag149) 2290-- Defined in all entities. Set if the entity is a package or subprogram 2291-- entity for a compilation unit other than a subunit (since we treat 2292-- subunits as part of the same compilation operation as the ultimate 2293-- parent, we do not consider them to be separate units for this flag). 2294 2295-- Is_Completely_Hidden (Flag103) 2296-- Defined on discriminants. Only set on girder discriminants of 2297-- untagged types. When set, the entity is a girder discriminant of a 2298-- derived untagged type which is not directly visible in the derived 2299-- type because the derived type or one of its ancestors have renamed the 2300-- discriminants in the root type. Note: there are girder discriminants 2301-- which are not Completely_Hidden (e.g. discriminants of a root type). 2302 2303-- Is_Composite_Type (synthesized) 2304-- Applies to all entities, true for all composite types and 2305-- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but 2306-- not both) is true of any type. 2307 2308-- Is_Concurrent_Record_Type (Flag20) 2309-- Defined in record types and subtypes. Set if the type was created 2310-- by the expander to represent a task or protected type. For every 2311-- concurrent type, such as record type is constructed, and task and 2312-- protected objects are instances of this record type at runtime 2313-- (The backend will replace declarations of the concurrent type using 2314-- the declarations of the corresponding record type). See Exp_Ch9 for 2315-- further details. 2316 2317-- Is_Concurrent_Type (synthesized) 2318-- Applies to all entities, true for task types and subtypes and for 2319-- protected types and subtypes. 2320 2321-- Is_Constant_Object (synthesized) 2322-- Applies to all entities, true for E_Constant, E_Loop_Parameter, and 2323-- E_In_Parameter entities. 2324 2325-- Is_Constrained (Flag12) 2326-- Defined in types or subtypes which may have index, discriminant 2327-- or range constraint (i.e. array types and subtypes, record types 2328-- and subtypes, string types and subtypes, and all numeric types). 2329-- Set if the type or subtype is constrained. 2330 2331-- Is_Constr_Subt_For_U_Nominal (Flag80) 2332-- Defined in all types and subtypes. Set only for the constructed 2333-- subtype of an object whose nominal subtype is unconstrained. Note 2334-- that the constructed subtype itself will be constrained. 2335 2336-- Is_Constr_Subt_For_UN_Aliased (Flag141) 2337-- Defined in all types and subtypes. This flag can be set only if 2338-- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in 2339-- addition the object concerned is aliased. This flag is used by 2340-- the backend to determine whether a template must be constructed. 2341 2342-- Is_Constructor (Flag76) 2343-- Defined in function and procedure entities. Set if a pragma 2344-- CPP_Constructor applies to the subprogram. 2345 2346-- Is_Controlled (Flag42) [base type only] 2347-- Defined in all type entities. Indicates that the type is controlled, 2348-- i.e. is either a descendant of Ada.Finalization.Controlled or of 2349-- Ada.Finalization.Limited_Controlled. 2350 2351-- Is_Controlled_Active (synth) [base type only] 2352-- Defined in all type entities. Set if Is_Controlled is set for the 2353-- type, and Disable_Controlled is not set. 2354 2355-- Is_Controlling_Formal (Flag97) 2356-- Defined in all Formal_Kind entities. Marks the controlling parameters 2357-- of dispatching operations. 2358 2359-- Is_CPP_Class (Flag74) 2360-- Defined in all type entities, set only for tagged types to which a 2361-- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied. 2362 2363-- Is_Decimal_Fixed_Point_Type (synthesized) 2364-- Applies to all type entities, true for decimal fixed point 2365-- types and subtypes. 2366 2367-- Is_Default_Init_Cond_Procedure (Flag132) 2368-- Defined in functions and procedures. Set for a generated procedure 2369-- which verifies the assumption of pragma Default_Initial_Condition. 2370 2371-- Is_Descendent_Of_Address (Flag223) 2372-- Defined in all entities. True if the entity is type System.Address, 2373-- or (recursively) a subtype or derived type of System.Address. 2374 2375-- Is_Discrete_Or_Fixed_Point_Type (synthesized) 2376-- Applies to all entities, true for all discrete types and subtypes 2377-- and all fixed-point types and subtypes. 2378 2379-- Is_Discrete_Type (synthesized) 2380-- Applies to all entities, true for all discrete types and subtypes 2381 2382-- Is_Discrim_SO_Function (Flag176) 2383-- Defined in all entities. Set only in E_Function entities that Layout 2384-- creates to compute discriminant-dependent dynamic size/offset values. 2385 2386-- Is_Discriminant_Check_Function (Flag264) 2387-- Defined in all entities. Set only in E_Function entities for functions 2388-- created to do discriminant checks. 2389 2390-- Is_Discriminal (synthesized) 2391-- Applies to all entities, true for renamings of discriminants. Such 2392-- entities appear as constants or IN parameters. 2393 2394-- Is_Dispatch_Table_Entity (Flag234) 2395-- Applies to all entities. Set to indicate to the backend that this 2396-- entity is associated with a dispatch table. 2397 2398-- Is_Dispatching_Operation (Flag6) 2399-- Defined in all entities. Set for procedures, functions, generic 2400-- procedures, and generic functions if the corresponding operation 2401-- is dispatching. 2402 2403-- Is_Dynamic_Scope (synthesized) 2404-- Applies to all Entities. Returns True if the entity is a dynamic 2405-- scope (i.e. a block, subprogram, task_type, entry 2406-- or extended return statement). 2407 2408-- Is_Elementary_Type (synthesized) 2409-- Applies to all entities, true for all elementary types and 2410-- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but 2411-- not both) is true of any type. 2412 2413-- Is_Eliminated (Flag124) 2414-- Defined in type entities, subprogram entities, and object entities. 2415-- Indicates that the corresponding entity has been eliminated by use 2416-- of pragma Eliminate. Also used to mark subprogram entities whose 2417-- declaration and body are within unreachable code that is removed. 2418 2419-- Is_Entry (synthesized) 2420-- Applies to all entities, True only for entry and entry family 2421-- entities and False for all other entity kinds. 2422 2423-- Is_Entry_Formal (Flag52) 2424-- Defined in all entities. Set only for entry formals (which can only 2425-- be in, in-out or out parameters). This flag is used to speed up the 2426-- test for the need to replace references in Exp_Ch2. 2427 2428-- Is_Enumeration_Type (synthesized) 2429-- Defined in all entities, true for enumeration types and subtypes 2430 2431-- Is_Exported (Flag99) 2432-- Defined in all entities. Set if the entity is exported. For now we 2433-- only allow the export of constants, exceptions, functions, procedures 2434-- and variables, but that may well change later on. Exceptions can only 2435-- be exported in the Java VM implementation of GNAT, which is retired. 2436 2437-- Is_External_State (synthesized) 2438-- Applies to all entities, true for abstract states that are subject to 2439-- option External. 2440 2441-- Is_Finalizer (synthesized) 2442-- Applies to all entities, true for procedures containing finalization 2443-- code to process local or library level objects. 2444 2445-- Is_First_Subtype (Flag70) 2446-- Defined in all entities. True for first subtypes (RM 3.2.1(6)), 2447-- i.e. the entity in the type declaration that introduced the type. 2448-- This may be the base type itself (e.g. for record declarations and 2449-- enumeration type declarations), or it may be the first subtype of 2450-- an anonymous base type (e.g. for integer type declarations or 2451-- constrained array declarations). 2452 2453-- Is_Fixed_Point_Type (synthesized) 2454-- Applies to all entities, true for decimal and ordinary fixed 2455-- point types and subtypes. 2456 2457-- Is_Floating_Point_Type (synthesized) 2458-- Applies to all entities, true for float types and subtypes 2459 2460-- Is_Formal (synthesized) 2461-- Applies to all entities, true for IN, IN OUT and OUT parameters 2462 2463-- Is_Formal_Object (synthesized) 2464-- Applies to all entities, true for generic IN and IN OUT parameters 2465 2466-- Is_Formal_Subprogram (Flag111) 2467-- Defined in all entities. Set for generic formal subprograms. 2468 2469-- Is_For_Access_Subtype (Flag118) 2470-- Defined in E_Private_Subtype and E_Record_Subtype entities. Means the 2471-- sole purpose of the type is to be designated by an Access_Subtype and 2472-- hence should not be expanded into components because the type may not 2473-- have been found or frozen yet. 2474 2475-- Is_Frozen (Flag4) 2476-- Defined in all type and subtype entities. Set if type or subtype has 2477-- been frozen. 2478 2479-- Is_Generic_Actual_Subprogram (Flag274) 2480-- Defined on functions and procedures. Set on the entity of the renaming 2481-- declaration created within an instance for an actual subprogram. 2482-- Used to generate constraint checks on calls to these subprograms, even 2483-- within an instance of a predefined run-time unit, in which checks 2484-- are otherwise suppressed. 2485-- 2486-- The flag is also set on the entity of the expression function created 2487-- within an instance, for a function that has external axiomatization, 2488-- for use in GNATprove mode. 2489 2490-- Is_Generic_Actual_Type (Flag94) 2491-- Defined in all type and subtype entities. Set in the subtype 2492-- declaration that renames the generic formal as a subtype of the 2493-- actual. Guarantees that the subtype is not static within the instance. 2494-- Also used during analysis of an instance, to simplify resolution of 2495-- accidental overloading that occurs when different formal types get the 2496-- same actual. 2497 2498-- Is_Generic_Instance (Flag130) 2499-- Defined in all entities. Set to indicate that the entity is an 2500-- instance of a generic unit, or a formal package (which is an instance 2501-- of the template). 2502 2503-- Is_Generic_Subprogram (synthesized) 2504-- Applies to all entities. Yields True for a generic subprogram 2505-- (generic function, generic subprogram), False for all other entities. 2506 2507-- Is_Generic_Type (Flag13) 2508-- Defined in all entities. Set for types which are generic formal types. 2509-- Such types have an Ekind that corresponds to their classification, so 2510-- the Ekind cannot be used to identify generic formal types. 2511 2512-- Is_Generic_Unit (synthesized) 2513-- Applies to all entities. Yields True for a generic unit (generic 2514-- package, generic function, generic procedure), and False for all 2515-- other entities. 2516 2517-- Is_Ghost_Entity (synthesized) 2518-- Applies to all entities. Yields True for abstract states, [generic] 2519-- packages, [generic] subprograms, components, discriminants, formal 2520-- parameters, objects, package bodies, subprogram bodies, and [sub]types 2521-- subject to pragma Ghost or those that inherit the Ghost propery from 2522-- an enclosing construct. 2523 2524-- Is_Hidden (Flag57) 2525-- Defined in all entities. Set for all entities declared in the 2526-- private part or body of a package. Also marks generic formals of a 2527-- formal package declared without a box. For library level entities, 2528-- this flag is set if the entity is not publicly visible. This flag 2529-- is reset when compiling the body of the package where the entity 2530-- is declared, when compiling the private part or body of a public 2531-- child unit, and when compiling a private child unit (see Install_ 2532-- Private_Declaration in sem_ch7). 2533 2534-- Is_Hidden_Non_Overridden_Subpgm (Flag2) 2535-- Defined in all entities. Set for implicitly declared subprograms 2536-- that require overriding or are null procedures, and are hidden by 2537-- a non-fully conformant homograph with the same characteristics 2538-- (Ada RM 8.3 12.3/2). 2539 2540-- Is_Hidden_Open_Scope (Flag171) 2541-- Defined in all entities. Set for a scope that contains the 2542-- instantiation of a child unit, and whose entities are not visible 2543-- during analysis of the instance. 2544 2545-- Is_Ignored_Ghost_Entity (Flag278) 2546-- Applies to all entities. Set for abstract states, [generic] packages, 2547-- [generic] subprograms, components, discriminants, formal parameters, 2548-- objects, package bodies, subprogram bodies, and [sub]types subject to 2549-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2550-- subject to Assertion_Policy Ghost => Ignore. 2551 2552-- Is_Immediately_Visible (Flag7) 2553-- Defined in all entities. Set if entity is immediately visible, i.e. 2554-- is defined in some currently open scope (RM 8.3(4)). 2555 2556-- Is_Implementation_Defined (Flag254) 2557-- Defined in all entities. Set if a pragma Implementation_Defined is 2558-- applied to the pragma. Used to mark all implementation defined 2559-- identifiers in standard library packages, and to implement the 2560-- restriction No_Implementation_Identifiers. 2561 2562-- Is_Imported (Flag24) 2563-- Defined in all entities. Set if the entity is imported. For now we 2564-- only allow the import of exceptions, functions, procedures, packages. 2565-- and variables. Exceptions, packages and types can only be imported in 2566-- the Java VM implementation, which is retired. 2567 2568-- Is_Incomplete_Or_Private_Type (synthesized) 2569-- Applies to all entities, true for private and incomplete types 2570 2571-- Is_Incomplete_Type (synthesized) 2572-- Applies to all entities, true for incomplete types and subtypes 2573 2574-- Is_Independent (Flag268) 2575-- Defined in all type entities, and also in constants, components and 2576-- variables. Set if a valid pragma or aspect Independent applies to the 2577-- entity, or if a valid pragma or aspect Independent_Components applies 2578-- to the enclosing record type for a component. Also set if a pragma 2579-- Shared or pragma Atomic applies to the entity. In the case of private 2580-- and incomplete types, this flag is set in both the partial view and 2581-- the full view. 2582 2583-- Is_Inlined (Flag11) 2584-- Defined in all entities. Set for functions and procedures which are 2585-- to be inlined. For subprograms created during expansion, this flag 2586-- may be set directly by the expander to request inlining. Also set 2587-- for packages that contain inlined subprograms, whose bodies must be 2588-- be compiled. Is_Inlined is also set on generic subprograms and is 2589-- inherited by their instances. It is also set on the body entities 2590-- of inlined subprograms. See also Has_Pragma_Inline. 2591 2592-- Is_Inlined_Always (Flag1) 2593-- Defined in subprograms. Set for functions and procedures which are 2594-- always inlined in GNATprove mode. GNATprove uses this flag to know 2595-- when a body does not need to be analyzed. The value of this flag is 2596-- only meaningful if Body_To_Inline is not Empty for the subprogram. 2597 2598-- Is_Instantiated (Flag126) 2599-- Defined in generic packages and generic subprograms. Set if the unit 2600-- is instantiated from somewhere in the extended main source unit. This 2601-- flag is used to control warnings about the unit being uninstantiated. 2602-- Also set in a package that is used as an actual for a generic package 2603-- formal in an instantiation. Also set on a parent instance, in the 2604-- instantiation of a child, which is implicitly declared in the parent. 2605 2606-- Is_Integer_Type (synthesized) 2607-- Applies to all entities, true for integer types and subtypes 2608 2609-- Is_Interface (Flag186) 2610-- Defined in record types and subtypes. Set to indicate that the current 2611-- entity corresponds with an abstract interface. Because abstract 2612-- interfaces are conceptually a special kind of abstract tagged types 2613-- we represent them by means of tagged record types and subtypes 2614-- marked with this attribute. This allows us to reuse most of the 2615-- compiler support for abstract tagged types to implement interfaces 2616-- (Ada 2005: AI-251). 2617 2618-- Is_Internal (Flag17) 2619-- Defined in all entities. Set to indicate an entity created during 2620-- semantic processing (e.g. an implicit type, or a temporary). The 2621-- current uses of this flag are: 2622-- 2623-- 1) Internal entities (such as temporaries generated for the result 2624-- of an inlined function call or dummy variables generated for the 2625-- debugger). Set to indicate that they need not be initialized, even 2626-- when scalars are initialized or normalized; 2627-- 2628-- 2) Predefined primitives of tagged types. Set to mark that they 2629-- have specific properties: first they are primitives even if they 2630-- are not defined in the type scope (the freezing point is not 2631-- necessarily in the same scope), and second the predefined equality 2632-- can be overridden by a user-defined equality, no body will be 2633-- generated in this case. 2634-- 2635-- 3) Object declarations generated by the expander that are implicitly 2636-- imported or exported so that they can be marked in Sprint output. 2637-- 2638-- 4) Internal entities in the list of primitives of tagged types that 2639-- are used to handle secondary dispatch tables. These entities have 2640-- also the attribute Interface_Alias. 2641 2642-- Is_Interrupt_Handler (Flag89) 2643-- Defined in procedures. Set if a pragma Interrupt_Handler applies 2644-- to the procedure. The procedure must be parameterless, and on all 2645-- targets except AAMP it must be a protected procedure. 2646 2647-- Is_Intrinsic_Subprogram (Flag64) 2648-- Defined in functions and procedures. It is set if a valid pragma 2649-- Interface or Import is present for this subprogram specifying pragma 2650-- Intrinsic. Valid means that the name and profile of the subprogram 2651-- match the requirements of one of the recognized intrinsic subprograms 2652-- (see package Sem_Intr for details). Note: the value of Convention for 2653-- such an entity will be set to Convention_Intrinsic, but it is the 2654-- setting of Is_Intrinsic_Subprogram, NOT simply having convention set 2655-- to intrinsic, which causes intrinsic code to be generated. 2656 2657-- Is_Invariant_Procedure (Flag257) 2658-- Defined in functions and procedures. Set for a generated invariant 2659-- procedure to identify it easily. 2660 2661-- Is_Itype (Flag91) 2662-- Defined in all entities. Set to indicate that a type is an Itype, 2663-- which means that the declaration for the type does not appear 2664-- explicitly in the tree. Instead the backend will elaborate the type 2665-- when it is first used. Has_Delayed_Freeze can be set for Itypes, and 2666-- the meaning is that the first use (the one which causes the type to be 2667-- defined) will be the freeze node. Note that an important restriction 2668-- on Itypes is that the first use of such a type (the one that causes it 2669-- to be defined) must be in the same scope as the type. 2670 2671-- Is_Known_Non_Null (Flag37) 2672-- Defined in all entities. Relevant (and can be set) only for 2673-- objects of an access type. It is set if the object is currently 2674-- known to have a non-null value (meaning that no access checks 2675-- are needed). The indication can for example come from assignment 2676-- of an access parameter or an allocator whose value is known non-null. 2677-- 2678-- Note: this flag is set according to the sequential flow of the 2679-- program, watching the current value of the variable. However, this 2680-- processing can miss cases of changing the value of an aliased or 2681-- constant object, so even if this flag is set, it should not be 2682-- believed if the variable is aliased or volatile. It would be a 2683-- little neater to avoid the flag being set in the first place in 2684-- such cases, but that's trickier, and there is only one place that 2685-- tests the value anyway. 2686-- 2687-- The flag is dynamically set and reset as semantic analysis and 2688-- expansion proceeds. Its value is meaningless once the tree is 2689-- fully constructed, since it simply indicates the last state. 2690-- Thus this flag has no meaning to the backend. 2691 2692-- Is_Known_Null (Flag204) 2693-- Defined in all entities. Relevant (and can be set ) only for 2694-- objects of an access type. It is set if the object is currently known 2695-- to have a null value (meaning that a dereference will surely raise 2696-- constraint error exception). The indication can come from an 2697-- assignment or object declaration. 2698-- 2699-- The comments above about sequential flow and aliased and volatile for 2700-- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag. 2701 2702-- Is_Known_Valid (Flag170) 2703-- Defined in all entities. Relevant for types (and subtype) and 2704-- for objects (and enumeration literals) of a discrete type. 2705-- 2706-- The purpose of this flag is to implement the requirement stated 2707-- in (RM 13.9.1(9-11)) which require that the use of possibly invalid 2708-- values may not cause programs to become erroneous. See the function 2709-- Checks.Expr_Known_Valid for further details. Note that the setting 2710-- is conservative, in the sense that if the flag is set, it must be 2711-- right. If the flag is not set, nothing is known about the validity. 2712-- 2713-- For enumeration literals, the flag is always set, since clearly 2714-- an enumeration literal represents a valid value. Range checks 2715-- where necessary will ensure that this valid value is appropriate. 2716-- 2717-- For objects, the flag indicates the state of knowledge about the 2718-- current value of the object. This may be modified during expansion, 2719-- and thus the final value is not relevant to the backend. 2720-- 2721-- For types and subtypes, the flag is set if all possible bit patterns 2722-- of length Object_Size (i.e. Esize of the type) represent valid values 2723-- of the type. In general for such tytpes, all values are valid, the 2724-- only exception being the case where an object of the type has an 2725-- explicit size that is greater than Object_Size. 2726-- 2727-- For non-discrete objects, the setting of the Is_Known_Valid flag is 2728-- not defined, and is not relevant, since the considerations of the 2729-- requirement in (RM 13.9.1(9-11)) do not apply. 2730-- 2731-- The flag is dynamically set and reset as semantic analysis and 2732-- expansion proceeds. Its value is meaningless once the tree is 2733-- fully constructed, since it simply indicates the last state. 2734-- Thus this flag has no meaning to the backend. 2735 2736-- Is_Limited_Composite (Flag106) 2737-- Defined in all entities. Set for composite types that have a limited 2738-- component. Used to enforce the rule that operations on the composite 2739-- type that depend on the full view of the component do not become 2740-- visible until the immediate scope of the composite type itself 2741-- (RM 7.3.1 (5)). 2742 2743-- Is_Limited_Interface (Flag197) 2744-- Defined in record types and subtypes. True for interface types, if 2745-- interface is declared limited, task, protected, or synchronized, or 2746-- is derived from a limited interface. 2747 2748-- Is_Limited_Record (Flag25) 2749-- Defined in all entities. Set to true for record (sub)types if the 2750-- record is declared to be limited. Note that this flag is not set 2751-- simply because some components of the record are limited. 2752 2753-- Is_Local_Anonymous_Access (Flag194) 2754-- Defined in access types. Set for an anonymous access type to indicate 2755-- that the type is created for a record component with an access 2756-- definition, an array component, or (pre-Ada 2012) a standalone object. 2757-- Such anonymous types have an accessibility level equal to that of the 2758-- declaration in which they appear, unlike the anonymous access types 2759-- that are created for access parameters, access discriminants, and 2760-- (as of Ada 2012) stand-alone objects. 2761 2762-- Is_Machine_Code_Subprogram (Flag137) 2763-- Defined in subprogram entities. Set to indicate that the subprogram 2764-- is a machine code subprogram (i.e. its body includes at least one 2765-- code statement). Also indicates that all necessary semantic checks 2766-- as required by RM 13.8(3) have been performed. 2767 2768-- Is_Modular_Integer_Type (synthesized) 2769-- Applies to all entities. True if entity is a modular integer type 2770 2771-- Is_Non_Static_Subtype (Flag109) 2772-- Defined in all type and subtype entities. It is set in some (but not 2773-- all) cases in which a subtype is known to be non-static. Before this 2774-- flag was added, the computation of whether a subtype was static was 2775-- entirely synthesized, by looking at the bounds, and the immediate 2776-- subtype parent. However, this method does not work for some Itypes 2777-- that have no parent set (and the only way to find the immediate 2778-- subtype parent is to go through the tree). For now, this flag is set 2779-- conservatively, i.e. if it is set then for sure the subtype is non- 2780-- static, but if it is not set, then the type may or may not be static. 2781-- Thus the test for a static subtype is that this flag is clear AND that 2782-- the bounds are static AND that the parent subtype (if available to be 2783-- tested) is static. Eventually we should make sure this flag is always 2784-- set right, at which point, these comments can be removed, and the 2785-- tests for static subtypes greatly simplified. 2786 2787-- Is_Null_Init_Proc (Flag178) 2788-- Defined in procedure entities. Set for generated init proc procedures 2789-- (used to initialize composite types), if the code for the procedure 2790-- is null (i.e. is a return and nothing else). Such null initialization 2791-- procedures are generated in case some client is compiled using the 2792-- Initialize_Scalars pragma, generating a call to this null procedure, 2793-- but there is no need to call such procedures within a compilation 2794-- unit, and this flag is used to suppress such calls. 2795 2796-- Is_Null_State (synthesized) 2797-- Applies to all entities, true for an abstract state declared with 2798-- keyword null. 2799 2800-- Is_Numeric_Type (synthesized) 2801-- Applies to all entities, true for all numeric types and subtypes 2802-- (integer, fixed, float). 2803 2804-- Is_Object (synthesized) 2805-- Applies to all entities, true for entities representing objects, 2806-- including generic formal parameters. 2807 2808-- Is_Obsolescent (Flag153) 2809-- Defined in all entities. Set for any entity to which a valid pragma 2810-- or aspect Obsolescent applies. 2811 2812-- Is_Only_Out_Parameter (Flag226) 2813-- Defined in formal parameter entities. Set if this parameter is the 2814-- only OUT parameter for this formal part. If there is more than one 2815-- out parameter, or if there is some other IN OUT parameter then this 2816-- flag is not set in any of them. Used in generation of warnings. 2817 2818-- Is_Ordinary_Fixed_Point_Type (synthesized) 2819-- Applies to all entities, true for ordinary fixed point types and 2820-- subtypes. 2821 2822-- Is_Package_Body_Entity (Flag160) 2823-- Defined in all entities. Set for entities defined at the top level 2824-- of a package body. Used to control externally generated names. 2825 2826-- Is_Package_Or_Generic_Package (synthesized) 2827-- Applies to all entities. True for packages and generic packages. 2828-- False for all other entities. 2829 2830-- Is_Packed (Flag51) [implementation base type only] 2831-- Defined in all type entities. This flag is set only for record and 2832-- array types which have a packed representation. There are three 2833-- cases which cause packing: 2834-- 2835-- 1. Explicit use of pragma Pack for an array of package components 2836-- 2. Explicit use of pragma Pack to pack a record 2837-- 4. Setting Component_Size of an array to a bit-packable value 2838-- 3. Indexing an array with a non-standard enumeration type. 2839-- 2840-- For records, Is_Packed is always set if Has_Pragma_Pack is set, 2841-- and can also be set on its own in a derived type which inherited 2842-- its packed status. 2843-- 2844-- For arrays, Is_Packed is set if an array is bit packed (i.e. the 2845-- component size is known at compile time and is 1-7, 9-15 or 17-31), 2846-- or if the array has one or more index types that are enumeration 2847-- types with non-standard representations (in GNAT, we store such 2848-- arrays compactly, using the Pos of the enumeration type value). 2849-- 2850-- As for the case of records, Is_Packed can be set on its own for a 2851-- derived type, with the same dual before/after freeze meaning. 2852-- Is_Packed can also be set as the result of an explicit component 2853-- size clause that specifies an appropriate component size. 2854-- 2855-- In the bit packed array case, Is_Bit_Packed_Array will be set in 2856-- the bit packed case once the array type is frozen. 2857-- 2858-- Before an array type is frozen, Is_Packed will always be set if 2859-- Has_Pragma_Pack is set. Before the freeze point, it is not possible 2860-- to know the component size, since the component type is not frozen 2861-- until the array type is frozen. Thus Is_Packed for an array type 2862-- before it is frozen means that packed is required. Then if it turns 2863-- out that the component size is not suitable for bit packing, the 2864-- Is_Packed flag gets turned off. 2865 2866-- Is_Packed_Array (synth) 2867-- Applies to all entities, true if entity is for a packed array. 2868 2869-- Is_Packed_Array_Impl_Type (Flag138) 2870-- Defined in all entities. This flag is set on the entity for the type 2871-- used to implement a packed array (either a modular type, or a subtype 2872-- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only 2873-- if the type appears in the Packed_Array_Impl_Type field of some other 2874-- entity. It is used by the backend to activate the special processing 2875-- for such types (unchecked conversions that would not otherwise be 2876-- allowed are allowed for such types). If Is_Packed_Array_Impl_Type is 2877-- set in an entity, then the Original_Array_Type field of this entity 2878-- points to the array type for which this is the Packed_Array_Impl_Type. 2879 2880-- Is_Param_Block_Component_Type (Flag215) [base type only] 2881-- Defined in access types. Set to indicate that a type is the type of a 2882-- component of the parameter block record type generated by the compiler 2883-- for an entry or a select statement. Read by CodePeer. 2884 2885-- Is_Potentially_Use_Visible (Flag9) 2886-- Defined in all entities. Set if entity is potentially use visible, 2887-- i.e. it is defined in a package that appears in a currently active 2888-- use clause (RM 8.4(8)). Note that potentially use visible entities 2889-- are not necessarily use visible (RM 8.4(9-11)). 2890 2891-- Is_Predicate_Function (Flag255) 2892-- Present in functions and procedures. Set for generated predicate 2893-- functions. 2894 2895-- Is_Predicate_Function_M (Flag256) 2896-- Present in functions and procedures. Set for special version of 2897-- predicate function generated for use in membership tests, where 2898-- raise expressions are transformed to return False. 2899 2900-- Is_Preelaborated (Flag59) 2901-- Defined in all entities, set in E_Package and E_Generic_Package 2902-- entities to which a pragma Preelaborate is applied, and also in 2903-- all entities within such packages. Note that the fact that this 2904-- flag is set does not necesarily mean that no elaboration code is 2905-- generated for the package. 2906 2907-- Is_Primitive (Flag218) 2908-- Defined in overloadable entities and in generic subprograms. Set to 2909-- indicate that this is a primitive operation of some type, which may 2910-- be a tagged type or an untagged type. Used to verify overriding 2911-- indicators in bodies. 2912 2913-- Is_Primitive_Wrapper (Flag195) 2914-- Defined in functions and procedures created by the expander to serve 2915-- as an indirection mechanism to overriding primitives of concurrent 2916-- types, entries and protected procedures. 2917 2918-- Is_Prival (synthesized) 2919-- Applies to all entities, true for renamings of private protected 2920-- components. Such entities appear as constants or variables. 2921 2922-- Is_Private_Composite (Flag107) 2923-- Defined in composite types that have a private component. Used to 2924-- enforce the rule that operations on the composite type that depend 2925-- on the full view of the component, do not become visible until the 2926-- immediate scope of the composite type itself (7.3.1 (5)). Both this 2927-- flag and Is_Limited_Composite are needed. 2928 2929-- Is_Private_Descendant (Flag53) 2930-- Defined in entities that can represent library units (packages, 2931-- functions, procedures). Set if the library unit is itself a private 2932-- child unit, or if it is the descendent of a private child unit. 2933 2934-- Is_Private_Primitive (Flag245) 2935-- Defined in subprograms. Set if the operation is a primitive of a 2936-- tagged type (procedure or function dispatching on result) whose 2937-- full view has not been seen. Used in particular for primitive 2938-- subprograms of a synchronized type declared between the two views 2939-- of the type, so that the wrapper built for such a subprogram can 2940-- be given the proper signature. 2941 2942-- Is_Private_Type (synthesized) 2943-- Applies to all entities, true for private types and subtypes, 2944-- as well as for record with private types as subtypes. 2945 2946-- Is_Processed_Transient (Flag252) 2947-- Defined in variables, loop parameters, and constants, including the 2948-- loop parameters of generalized iterators. Set when a transient object 2949-- needs to be finalized and has already been processed by the transient 2950-- scope machinery. This flag signals the general finalization mechanism 2951-- to ignore the transient object. 2952 2953-- Is_Protected_Component (synthesized) 2954-- Applicable to all entities, true if the entity denotes a private 2955-- component of a protected type. 2956 2957-- Is_Protected_Interface (synthesized) 2958-- Defined in types that are interfaces. True if interface is declared 2959-- protected, or is derived from protected interfaces. 2960 2961-- Is_Protected_Record_Type (synthesized) 2962-- Applies to all entities, true if Is_Concurrent_Record_Type is true and 2963-- Corresponding_Concurrent_Type is a protected type. 2964 2965-- Is_Protected_Type (synthesized) 2966-- Applies to all entities, true for protected types and subtypes 2967 2968-- Is_Public (Flag10) 2969-- Defined in all entities. Set to indicate that an entity defined in 2970-- one compilation unit can be referenced from other compilation units. 2971-- If this reference causes a reference in the generated code, for 2972-- example in the case of a variable name, then the backend will generate 2973-- an appropriate external name for use by the linker. 2974 2975-- Is_Pure (Flag44) 2976-- Defined in all entities. Set in all entities of a unit to which a 2977-- pragma Pure is applied except for non-intrinsic imported subprograms, 2978-- and also set for the entity of the unit itself. In addition, this 2979-- flag may be set for any other functions or procedures that are known 2980-- to be side effect free, so in the case of subprograms, the Is_Pure 2981-- flag may be used by the optimizer to imply that it can assume freedom 2982-- from side effects (other than those resulting from assignment to out 2983-- parameters, or to objects designated by access parameters). 2984 2985-- Is_Pure_Unit_Access_Type (Flag189) 2986-- Defined in access type and subtype entities. Set if the type or 2987-- subtype appears in a pure unit. Used to give an error message at 2988-- freeze time if the access type has a storage pool. 2989 2990-- Is_RACW_Stub_Type (Flag244) 2991-- Defined in all types, true for the stub types generated for remote 2992-- access-to-class-wide types. 2993 2994-- Is_Raised (Flag224) 2995-- Defined in exception entities. Set if the entity is referenced by a 2996-- a raise statement. 2997 2998-- Is_Real_Type (synthesized) 2999-- Applies to all entities, true for real types and subtypes 3000 3001-- Is_Record_Type (synthesized) 3002-- Applies to all entities, true for record types and subtypes, 3003-- includes class-wide types and subtypes (which are also records). 3004 3005-- Is_Remote_Call_Interface (Flag62) 3006-- Defined in all entities. Set in E_Package and E_Generic_Package 3007-- entities to which a pragma Remote_Call_Interface is applied, and 3008-- also on entities declared in the visible part of such a package. 3009 3010-- Is_Remote_Types (Flag61) 3011-- Defined in all entities. Set in E_Package and E_Generic_Package 3012-- entities to which a pragma Remote_Types is applied, and also on 3013-- entities declared in the visible part of the spec of such a package. 3014-- Also set for types which are generic formal types to which the 3015-- pragma Remote_Access_Type applies. 3016 3017-- Is_Renaming_Of_Object (Flag112) 3018-- Defined in all entities, set only for a variable or constant for 3019-- which the Renamed_Object field is non-empty and for which the 3020-- renaming is handled by the front end, by macro substitution of 3021-- a copy of the (evaluated) name tree whereever the variable is used. 3022 3023-- Is_Return_Object (Flag209) 3024-- Defined in all object entities. True if the object is the return 3025-- object of an extended_return_statement; False otherwise. 3026 3027-- Is_Safe_To_Reevaluate (Flag249) 3028-- Defined in all entities. Set in variables that are initialized by 3029-- means of an assignment statement. When initialized their contents 3030-- never change and hence they can be seen by the backend as constants. 3031-- See also Is_True_Constant. 3032 3033-- Is_Scalar_Type (synthesized) 3034-- Applies to all entities, true for scalar types and subtypes 3035 3036-- Is_Shared_Passive (Flag60) 3037-- Defined in all entities. Set in E_Package and E_Generic_Package 3038-- entities to which a pragma Shared_Passive is applied, and also in 3039-- all entities within such packages. 3040 3041-- Is_Standard_Character_Type (synthesized) 3042-- Applies to all entities, true for types and subtypes whose root type 3043-- is one of the standard character types (Character, Wide_Character, or 3044-- Wide_Wide_Character). 3045 3046-- Is_Standard_String_Type (synthesized) 3047-- Applies to all entities, true for types and subtypes whose root 3048-- type is one of the standard string types (String, Wide_String, or 3049-- Wide_Wide_String). 3050 3051-- Is_Static_Type (Flag281) 3052-- Defined in entities. Only set for (sub)types. If set, indicates that 3053-- the type is known to be a static type (defined as a discrete type with 3054-- static bounds, a record all of whose component types are static types, 3055-- or an array, all of whose bounds are of a static type, and also have 3056-- a component type that is a static type). See Set_Uplevel_Type for more 3057-- information on how this flag is used. 3058 3059-- Is_Statically_Allocated (Flag28) 3060-- Defined in all entities. This can only be set for exception, 3061-- variable, constant, and type/subtype entities. If the flag is set, 3062-- then the variable or constant must be allocated statically rather 3063-- than on the local stack frame. For exceptions, the meaning is that 3064-- the exception data should be allocated statically (and indeed this 3065-- flag is always set for exceptions, since exceptions do not have 3066-- local scope). For a type, the meaning is that the type must be 3067-- elaborated at the global level rather than locally. No type marked 3068-- with this flag may depend on a local variable, or on any other type 3069-- which does not also have this flag set to True. For a variable or 3070-- or constant, if the flag is set, then the type of the object must 3071-- either be declared at the library level, or it must also have the 3072-- flag set (since to allocate the object statically, its type must 3073-- also be elaborated globally). 3074 3075-- Is_String_Type (synthesized) 3076-- Applies to all type entities. Determines if the given type is a 3077-- string type, i.e. it is directly a string type or string subtype, 3078-- or a string slice type, or an array type with one dimension and a 3079-- component type that is a character type. 3080 3081-- Is_Subprogram (synthesized) 3082-- Applies to all entities, true for function, procedure and operator 3083-- entities. 3084 3085-- Is_Subprogram_Or_Generic_Subprogram 3086-- Applies to all entities, true for function procedure and operator 3087-- entities, and also for the corresponding generic entities. 3088 3089-- Is_Synchronized_Interface (synthesized) 3090-- Defined in types that are interfaces. True if interface is declared 3091-- synchronized, task, or protected, or is derived from a synchronized 3092-- interface. 3093 3094-- Is_Synchronized_State (synthesized) 3095-- Applies to all entities, true for abstract states that are subject to 3096-- option Synchronous. 3097 3098-- Is_Tag (Flag78) 3099-- Defined in E_Component and E_Constant entities. For regular tagged 3100-- type this flag is set on the tag component (whose name is Name_uTag). 3101-- For CPP_Class tagged types, this flag marks the pointer to the main 3102-- vtable (i.e. the one to be extended by derivation). 3103 3104-- Is_Tagged_Type (Flag55) 3105-- Defined in all entities, set for an entity that is a tagged type 3106 3107-- Is_Task_Interface (synthesized) 3108-- Defined in types that are interfaces. True if interface is declared as 3109-- a task interface, or if it is derived from task interfaces. 3110 3111-- Is_Task_Record_Type (synthesized) 3112-- Applies to all entities. True if Is_Concurrent_Record_Type 3113-- Corresponding_Concurrent_Type is a task type. 3114 3115-- Is_Task_Type (synthesized) 3116-- Applies to all entities. True for task types and subtypes 3117 3118-- Is_Thunk (Flag225) 3119-- Defined in all entities. True for subprograms that are thunks: that is 3120-- small subprograms built by the expander for tagged types that cover 3121-- interface types. As part of the runtime call to an interface, thunks 3122-- displace the pointer to the object (pointer named "this" in the C++ 3123-- terminology) from a secondary dispatch table to the primary dispatch 3124-- table associated with a given tagged type; if the thunk is a function 3125-- that returns an object which covers an interface type then the thunk 3126-- displaces the pointer to the object from the primary dispatch table to 3127-- the secondary dispatch table associated with the interface type. Set 3128-- by Expand_Interface_Thunk and used by Expand_Call to handle extra 3129-- actuals associated with accessibility level. 3130 3131-- Is_Trivial_Subprogram (Flag235) 3132-- Defined in all entities. Set in subprograms where either the body 3133-- consists of a single null statement, or the first or only statement 3134-- of the body raises an exception. This is used for suppressing certain 3135-- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details. 3136 3137-- Is_True_Constant (Flag163) 3138-- Defined in all entities for constants and variables. Set in constants 3139-- and variables which have an initial value specified but which are 3140-- never assigned, partially or in the whole. For variables, it means 3141-- that the variable was initialized but never modified, and hence can be 3142-- treated as a constant by the code generator. For a constant, it means 3143-- that the constant was not modified by generated code (e.g. to set a 3144-- discriminant in an init proc). Assignments by user or generated code 3145-- will reset this flag. See also Is_Safe_To_Reevaluate. 3146 3147-- Is_Type (synthesized) 3148-- Applies to all entities, true for a type entity 3149 3150-- Is_Unchecked_Union (Flag117) [implementation base type only] 3151-- Defined in all entities. Set only in record types to which the 3152-- pragma Unchecked_Union has been validly applied. 3153 3154-- Is_Underlying_Record_View (Flag246) [base type only] 3155-- Defined in all entities. Set only in record types that represent the 3156-- underlying record view. This view is built for derivations of types 3157-- with unknown discriminants; it is a record with the same structure 3158-- as its corresponding record type, but whose parent is the full view 3159-- of the parent in the original type extension. 3160 3161-- Is_Unimplemented (Flag284) 3162-- Defined in all entities. Set for any entity to which a valid pragma 3163-- or aspect Unimplemented applies. 3164 3165-- Is_Unsigned_Type (Flag144) 3166-- Defined in all types, but can be set only for discrete and fixed-point 3167-- type and subtype entities. This flag is only valid if the entity is 3168-- frozen. If set it indicates that the representation is known to be 3169-- unsigned (i.e. that no negative values appear in the range). This is 3170-- normally just a reflection of the lower bound of the subtype or base 3171-- type, but there is one case in which the setting is non-obvious, 3172-- namely the case of an unsigned subtype of a signed type from which 3173-- a further subtype is obtained using variable bounds. This further 3174-- subtype is still unsigned, but this cannot be determined by looking 3175-- at its bounds or the bounds of the corresponding base type. 3176 3177-- Is_Uplevel_Referenced_Entity (Flag283) 3178-- Defined in all entities. Used when unnesting subprograms to indicate 3179-- that an entity is locally defined within a subprogram P, and there is 3180-- a reference to the entity within a subprogram nested within P (at any 3181-- depth). Set for uplevel referenced objects (variables, constants and 3182-- loop parameters), and also for upreferenced dynamic types, including 3183-- the cases where the reference is implicit (e.g. the type of an array 3184-- used for computing the location of an element in an array. This is 3185-- used internally in Exp_Unst, see this package for further details. 3186 3187-- Is_Valued_Procedure (Flag127) 3188-- Defined in procedure entities. Set if an Import_Valued_Procedure 3189-- or Export_Valued_Procedure pragma applies to the procedure entity. 3190 3191-- Is_Visible_Formal (Flag206) 3192-- Defined in all entities. Set for instances of the formals of a 3193-- formal package. Indicates that the entity must be made visible in the 3194-- body of the instance, to reproduce the visibility of the generic. 3195-- This simplifies visibility settings in instance bodies. 3196 3197-- Is_Visible_Lib_Unit (Flag116) 3198-- Defined in all (root or child) library unit entities. Once compiled, 3199-- library units remain chained to the entities in the parent scope, and 3200-- a separate flag must be used to indicate whether the names are visible 3201-- by selected notation, or not. 3202 3203-- Is_Volatile (Flag16) 3204-- Defined in all type entities, and also in constants, components and 3205-- variables. Set if a pragma Volatile applies to the entity. Also set 3206-- if pragma Shared or pragma Atomic applies to entity. In the case of 3207-- private or incomplete types, this flag is set in both the private 3208-- and full view. The flag is not set reliably on private subtypes, 3209-- and is always retrieved from the base type (but this is not a base- 3210-- type-only attribute because it applies to other entities). Note that 3211-- the backend should use Treat_As_Volatile, rather than Is_Volatile 3212-- to indicate code generation requirements for volatile variables. 3213-- Similarly, any front end test which is concerned with suppressing 3214-- optimizations on volatile objects should test Treat_As_Volatile 3215-- rather than testing this flag. 3216 3217-- Is_Volatile_Full_Access (Flag285) 3218-- Defined in all type entities, and also in constants, components, and 3219-- variables. Set if a pragma Volatile_Full_Access applies to the entity. 3220-- In the case of private and incomplete types, this flag is set in 3221-- both the partial view and the full view. 3222 3223-- Is_Wrapper_Package (synthesized) 3224-- Defined in package entities. Indicates that the package has been 3225-- created as a wrapper for a subprogram instantiation. 3226 3227-- Itype_Printed (Flag202) 3228-- Defined in all type and subtype entities. Set in Itypes if the Itype 3229-- has been printed by Sprint. This is used to avoid printing an Itype 3230-- more than once. 3231 3232-- Kill_Elaboration_Checks (Flag32) 3233-- Defined in all entities. Set by the expander to kill elaboration 3234-- checks which are known not to be needed. Equivalent in effect to 3235-- the use of pragma Suppress (Elaboration_Checks) for that entity 3236-- except that the effect is permanent and cannot be undone by a 3237-- subsequent pragma Unsuppress. 3238 3239-- Kill_Range_Checks (Flag33) 3240-- Defined in all entities. Equivalent in effect to the use of pragma 3241-- Suppress (Range_Checks) for that entity except that the result is 3242-- permanent and cannot be undone by a subsequent pragma Unsuppress. 3243-- This is currently only used in one odd situation in Sem_Ch3 for 3244-- record types, and it would be good to get rid of it??? 3245 3246-- Known_To_Have_Preelab_Init (Flag207) 3247-- Defined in all type and subtype entities. If set, then the type is 3248-- known to have preelaborable initialization. In the case of a partial 3249-- view of a private type, it is only possible for this to be set if a 3250-- pragma Preelaborable_Initialization is given for the type. For other 3251-- types, it is never set if the type does not have preelaborable 3252-- initialization, it may or may not be set if the type does have 3253-- preelaborable initialization. 3254 3255-- Last_Aggregate_Assignment (Node30) 3256-- Applies to controlled constants and variables initialized by an 3257-- aggregate. Points to the last statement associated with the expansion 3258-- of the aggregate. The attribute is used by the finalization machinery 3259-- when marking an object as successfully initialized. 3260 3261-- Last_Assignment (Node26) 3262-- Defined in entities for variables, and OUT or IN OUT formals. Set for 3263-- a local variable or formal to point to the left side of an assignment 3264-- statement assigning a value to the variable. Cleared if the value of 3265-- the entity is referenced. Used to warn about dubious assignment 3266-- statements whose value is not used. 3267 3268-- Last_Entity (Node20) 3269-- Defined in all entities which act as scopes to which a list of 3270-- associated entities is attached (blocks, class subtypes and types, 3271-- entries, functions, loops, packages, procedures, protected objects, 3272-- record types and subtypes, private types, task types and subtypes). 3273-- Points to the last entry in the list of associated entities chained 3274-- through the Next_Entity field. Empty if no entities are chained. 3275 3276-- Last_Formal (synthesized) 3277-- Applies to subprograms and subprogram types, and also in entries 3278-- and entry families. Returns last formal of the subprogram or entry. 3279-- The formals are the first entities declared in a subprogram or in 3280-- a subprogram type (the designated type of an Access_To_Subprogram 3281-- definition) or in an entry. 3282 3283-- Limited_View (Node23) 3284-- Defined in non-generic package entities that are not instances. Bona 3285-- fide package with the limited-view list through the first_entity and 3286-- first_private attributes. The elements of this list are the shadow 3287-- entities created for the types and local packages that are declared 3288-- in a package appearing in a limited_with clause (Ada 2005: AI-50217). 3289 3290-- Linker_Section_Pragma (Node33) 3291-- Present in constant, variable, type and subprogram entities. Points 3292-- to a linker section pragma that applies to the entity, or is Empty if 3293-- no such pragma applies. Note that for constants and variables, this 3294-- field may be set as a result of a linker section pragma applied to the 3295-- type of the object. 3296 3297-- Lit_Indexes (Node18) 3298-- Defined in enumeration types and subtypes. Non-empty only for the 3299-- case of an enumeration root type, where it contains the entity for 3300-- the generated indexes entity. See unit Exp_Imgv for full details of 3301-- the nature and use of this entity for implementing the Image and 3302-- Value attributes for the enumeration type in question. 3303 3304-- Lit_Strings (Node16) 3305-- Defined in enumeration types and subtypes. Non-empty only for the 3306-- case of an enumeration root type, where it contains the entity for 3307-- the literals string entity. See unit Exp_Imgv for full details of 3308-- the nature and use of this entity for implementing the Image and 3309-- Value attributes for the enumeration type in question. 3310 3311-- Low_Bound_Tested (Flag205) 3312-- Defined in all entities. Currently this can only be set for formal 3313-- parameter entries of a standard unconstrained one-dimensional array 3314-- or string type. Indicates that an explicit test of the low bound of 3315-- the formal appeared in the code, e.g. in a pragma Assert. If this 3316-- flag is set, warnings about assuming the index low bound to be one 3317-- are suppressed. 3318 3319-- Machine_Radix_10 (Flag84) 3320-- Defined in decimal types and subtypes, set if the Machine_Radix is 10, 3321-- as the result of the specification of a machine radix representation 3322-- clause. Note that it is possible for this flag to be set without 3323-- having Has_Machine_Radix_Clause True. This happens when a type is 3324-- derived from a type with a clause present. 3325 3326-- Master_Id (Node17) 3327-- Defined in access types and subtypes. Empty unless Has_Task is set for 3328-- the designated type, in which case it points to the entity for the 3329-- Master_Id for the access type master. Also set for access-to-limited- 3330-- class-wide types whose root may be extended with task components, and 3331-- for access-to-limited-interfaces because they can be used to reference 3332-- tasks implementing such interface. 3333 3334-- Materialize_Entity (Flag168) 3335-- Defined in all entities. Set only for renamed obects which should be 3336-- materialized for debugging purposes. This means that a memory location 3337-- containing the renamed address should be allocated. This is needed so 3338-- that the debugger can find the entity. 3339 3340-- May_Inherit_Delayed_Rep_Aspects (Flag262) 3341-- Defined in all entities for types and subtypes. Set if the type is 3342-- derived from a type which has delayed rep aspects (marked by the flag 3343-- Has_Delayed_Rep_Aspects being set). In this case, at the freeze point 3344-- for the derived type we know that the parent type is frozen, and if 3345-- a given attribute has not been set for the derived type, we copy the 3346-- value from the parent type. See Freeze.Inherit_Delayed_Rep_Aspects. 3347 3348-- Mechanism (Uint8) (returned as Mechanism_Type) 3349-- Defined in functions and non-generic formal parameters. Indicates 3350-- the mechanism to be used for the function return or for the formal 3351-- parameter. See full description in the spec of Sem_Mech. This field 3352-- is also set (to the default value of zero = Default_Mechanism) in a 3353-- subprogram body entity but not used in this context. 3354 3355-- Modulus (Uint17) [base type only] 3356-- Defined in modular types. Contains the modulus. For the binary case, 3357-- this will be a power of 2, but if Non_Binary_Modulus is set, then it 3358-- will not be a power of 2. 3359 3360-- Must_Be_On_Byte_Boundary (Flag183) 3361-- Defined in entities for types and subtypes. Set if objects of the type 3362-- must always be allocated on a byte boundary (more accurately a storage 3363-- unit boundary). The front end checks that component clauses respect 3364-- this rule, and the backend ensures that record packing does not 3365-- violate this rule. Currently the flag is set only for packed arrays 3366-- longer than 64 bits where the component size is not a power of 2. 3367 3368-- Must_Have_Preelab_Init (Flag208) 3369-- Defined in entities for types and subtypes. Set in the full type of a 3370-- private type or subtype if a pragma Has_Preelaborable_Initialization 3371-- is present for the private type. Used to check that the full type has 3372-- preelaborable initialization at freeze time (this has to be deferred 3373-- to the freeze point because of the rule about overriding Initialize). 3374 3375-- Needs_Debug_Info (Flag147) 3376-- Defined in all entities. Set if the entity requires normal debugging 3377-- information to be generated. This is true of all entities that have 3378-- Comes_From_Source set, and also transitively for entities associated 3379-- with such components (e.g. their types). It is true for all entities 3380-- in Debug_Generated_Code mode (-gnatD switch). This is the flag that 3381-- the backend should check to determine whether or not to generate 3382-- debugging information for an entity. Note that callers should always 3383-- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info, 3384-- so that the flag is set properly on subsidiary entities. 3385 3386-- Needs_No_Actuals (Flag22) 3387-- Defined in callable entities (subprograms, entries, access to 3388-- subprograms) which can be called without actuals because all of 3389-- their formals (if any) have default values. This flag simplifies the 3390-- resolution of the syntactic ambiguity involving a call to these 3391-- entities when the return type is an array type, and a call can be 3392-- interpreted as an indexing of the result of the call. It is also 3393-- used to resolve various cases of entry calls. 3394 3395-- Never_Set_In_Source (Flag115) 3396-- Defined in all entities, but can be set only for variables and 3397-- parameters. This flag is set if the object is never assigned a value 3398-- in user source code, either by assignment or by being used as an out 3399-- or in out parameter. Note that this flag is not reset from using an 3400-- initial value, so if you want to test for this case as well, test the 3401-- Has_Initial_Value flag also. 3402-- 3403-- This flag is only for the purposes of issuing warnings, it must not 3404-- be used by the code generator to indicate that the variable is in 3405-- fact a constant, since some assignments in generated code do not 3406-- count (for example, the call to an init proc to assign some but 3407-- not all of the fields in a partially initialized record). The code 3408-- generator should instead use the flag Is_True_Constant. 3409-- 3410-- For the purposes of this warning, the default assignment of access 3411-- variables to null is not considered the assignment of a value (so 3412-- the warning can be given for code that relies on this initial null 3413-- value when no other value is ever set). 3414-- 3415-- In variables and out parameters, if this flag is set after full 3416-- processing of the corresponding declarative unit, it indicates that 3417-- the variable or parameter was never set, and a warning message can 3418-- be issued. 3419-- 3420-- Note: this flag is initially set, and then cleared on encountering 3421-- any construct that might conceivably legitimately set the value. 3422-- Thus during the analysis of a declarative region and its associated 3423-- statement sequence, the meaning of the flag is "not set yet", and 3424-- once this analysis is complete the flag means "never assigned". 3425 3426-- Note: for variables appearing in package declarations, this flag is 3427-- never set. That is because there is no way to tell if some client 3428-- modifies the variable (or, in the case of variables in the private 3429-- part, if some child unit modifies the variables). 3430 3431-- Note: in the case of renamed objects, the flag must be set in the 3432-- ultimate renamed object. Clients noting a possible modification 3433-- should use the Note_Possible_Modification procedure in Sem_Util 3434-- rather than Set_Never_Set_In_Source precisely to deal properly with 3435-- the renaming possibility. 3436 3437-- Next_Component (synthesized) 3438-- Applies to record components. Returns the next component by following 3439-- the chain of declared entities until one is found which corresponds to 3440-- a component (Ekind is E_Component). Any internal types generated from 3441-- the subtype indications of the record components are skipped. Returns 3442-- Empty if no more components. 3443 3444-- Next_Component_Or_Discriminant (synthesized) 3445-- Similar to Next_Component, but includes components and discriminants 3446-- so the input can have either E_Component or E_Discriminant, and the 3447-- same is true for the result. Returns Empty if no more components or 3448-- discriminants in the record. 3449 3450-- Next_Discriminant (synthesized) 3451-- Applies to discriminants returned by First/Next_Discriminant. Returns 3452-- the next language-defined (ie: perhaps non-girder) discriminant by 3453-- following the chain of declared entities as long as the kind of the 3454-- entity corresponds to a discriminant. Note that the discriminants 3455-- might be the only components of the record. Returns Empty if there 3456-- are no more discriminants. 3457 3458-- Next_Entity (Node2) 3459-- Defined in all entities. The entities of a scope are chained, with 3460-- the head of the list being in the First_Entity field of the scope 3461-- entity. All entities use the Next_Entity field as a forward pointer 3462-- for this list, with Empty indicating the end of the list. Since this 3463-- field is in the base part of the entity, the access routines for this 3464-- field are in Sinfo. 3465 3466-- Next_Formal (synthesized) 3467-- Applies to the entity for a formal parameter. Returns the next formal 3468-- parameter of the subprogram or subprogram type. Returns Empty if there 3469-- are no more formals. 3470 3471-- Next_Formal_With_Extras (synthesized) 3472-- Applies to the entity for a formal parameter. Returns the next 3473-- formal parameter of the subprogram or subprogram type. Returns 3474-- Empty if there are no more formals. The list returned includes 3475-- all the extra formals (see description of Extra_Formal field) 3476 3477-- Next_Index (synthesized) 3478-- Applies to array types and subtypes and to string types and 3479-- subtypes. Yields the next index. The first index is obtained by 3480-- using the First_Index attribute, and then subsequent indexes are 3481-- obtained by applying Next_Index to the previous index. Empty is 3482-- returned to indicate that there are no more indexes. Note that 3483-- unlike most attributes in this package, Next_Index applies to 3484-- nodes for the indexes, not to entities. 3485 3486-- Next_Inlined_Subprogram (Node12) 3487-- Defined in subprograms. Used to chain inlined subprograms used in 3488-- the current compilation, in the order in which they must be compiled 3489-- by the backend to ensure that all inlinings are performed. 3490 3491-- Next_Literal (synthesized) 3492-- Applies to enumeration literals, returns the next literal, or 3493-- Empty if applied to the last literal. This is actually a synonym 3494-- for Next, but its use is preferred in this context. 3495 3496-- No_Dynamic_Predicate_On_Actual (Flag276) 3497-- Defined in discrete types. Set for generic formal types that are used 3498-- in loops and quantified expressions. The corresponing actual cannot 3499-- have dynamic predicates. 3500 3501-- No_Pool_Assigned (Flag131) [root type only] 3502-- Defined in access types. Set if a storage size clause applies to the 3503-- variable with a static expression value of zero. This flag is used to 3504-- generate errors if any attempt is made to allocate or free an instance 3505-- of such an access type. This is set only in the root type, since 3506-- derived types must have the same pool. 3507 3508-- No_Predicate_On_Actual (Flag275) 3509-- Defined in discrete types. Set for generic formal types that are used 3510-- in the spec of a generic package, in constructs that forbid discrete 3511-- types with predicates. 3512 3513-- No_Return (Flag113) 3514-- Defined in all entities. Always false except in the case of procedures 3515-- and generic procedures for which a pragma No_Return is given. 3516 3517-- No_Strict_Aliasing (Flag136) [base type only] 3518-- Defined in access types. Set to direct the backend to avoid any 3519-- optimizations based on an assumption about the aliasing status of 3520-- objects designated by the access type. For the case of the gcc 3521-- backend, the effect is as though all references to objects of 3522-- the type were compiled with -fno-strict-aliasing. This flag is 3523-- set if an unchecked conversion with the access type as a target 3524-- type occurs in the same source unit as the declaration of the 3525-- access type, or if an explicit pragma No_Strict_Aliasing applies. 3526 3527-- No_Tagged_Streams_Pragma (Node32) 3528-- Present in all subtype and type entities. Set for tagged types and 3529-- subtypes (i.e. entities with Is_Tagged_Type set True) if a valid 3530-- pragma/aspect applies to the type. 3531 3532-- Non_Binary_Modulus (Flag58) [base type only] 3533-- Defined in all subtype and type entities. Set for modular integer 3534-- types if the modulus value is other than a power of 2. 3535 3536-- Non_Limited_View (Node19) 3537-- Defined in abstract states and incomplete types that act as shadow 3538-- entities created when analysing a limited with clause (Ada 2005: 3539-- AI-50217). Points to the defining entity of the original declaration. 3540 3541-- Nonzero_Is_True (Flag162) [base type only] 3542-- Defined in enumeration types. Set if any non-zero value is to be 3543-- interpreted as true. Currently this is set for derived Boolean 3544-- types which have a convention of C, C++ or Fortran. 3545 3546-- Normalized_First_Bit (Uint8) 3547-- Defined in components and discriminants. Indicates the normalized 3548-- value of First_Bit for the component, i.e. the offset within the 3549-- lowest addressed storage unit containing part or all of the field. 3550-- Set to No_Uint if no first bit position is assigned yet. 3551 3552-- Normalized_Position (Uint14) 3553-- Defined in components and discriminants. Indicates the normalized 3554-- value of Position for the component, i.e. the offset in storage 3555-- units from the start of the record to the lowest addressed storage 3556-- unit containing part or all of the field. 3557 3558-- Normalized_Position_Max (Uint10) 3559-- Defined in components and discriminants. For almost all cases, this 3560-- is the same as Normalized_Position. The one exception is for the case 3561-- of a discriminated record containing one or more arrays whose length 3562-- depends on discriminants. In this case, the Normalized_Position_Max 3563-- field represents the maximum possible value of Normalized_Position 3564-- assuming min/max values for discriminant subscripts in all fields. 3565-- This is used by Layout in front end layout mode to properly computed 3566-- the maximum size such records (needed for allocation purposes when 3567-- there are default discriminants, and also for the 'Size value). 3568 3569-- Number_Dimensions (synthesized) 3570-- Applies to array types and subtypes. Returns the number of dimensions 3571-- of the array type or subtype as a value of type Pos. 3572 3573-- Number_Entries (synthesized) 3574-- Applies to concurrent types. Returns the number of entries that are 3575-- declared within the task or protected definition for the type. 3576 3577-- Number_Formals (synthesized) 3578-- Applies to subprograms and subprogram types. Yields the number of 3579-- formals as a value of type Pos. 3580 3581-- OK_To_Rename (Flag247) 3582-- Defined only in entities for variables. If this flag is set, it 3583-- means that if the entity is used as the initial value of an object 3584-- declaration, the object declaration can be safely converted into a 3585-- renaming to avoid an extra copy. This is set for variables which are 3586-- generated by the expander to hold the result of evaluating some 3587-- expression. Most notably, the local variables used to store the result 3588-- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It 3589-- is only worth setting this flag for composites, since for primitive 3590-- types, it is cheaper to do the copy. 3591 3592-- OK_To_Reorder_Components (Flag239) [base type only] 3593-- Defined in record types. Set if the backend is permitted to reorder 3594-- the components. If not set, the record must be layed out in the order 3595-- in which the components are declared textually. Currently this flag 3596-- can only be set by debug switches. 3597 3598-- Optimize_Alignment_Space (Flag241) 3599-- Defined in type, subtype, variable, and constant entities. This 3600-- flag records that the type or object is to be layed out in a manner 3601-- consistent with Optimize_Alignment (Space) mode. The compiler and 3602-- binder ensure a consistent view of any given type or object. If pragma 3603-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3604-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3605 3606-- Optimize_Alignment_Time (Flag242) 3607-- Defined in type, subtype, variable, and constant entities. This 3608-- flag records that the type or object is to be layed out in a manner 3609-- consistent with Optimize_Alignment (Time) mode. The compiler and 3610-- binder ensure a consistent view of any given type or object. If pragma 3611-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3612-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3613 3614-- Original_Access_Type (Node28) 3615-- Defined in E_Access_Subprogram_Type entities. Set only if the access 3616-- type was generated by the expander as part of processing an access 3617-- to protected subprogram type. Points to the access to protected 3618-- subprogram type. 3619 3620-- Original_Array_Type (Node21) 3621-- Defined in modular types and array types and subtypes. Set only if 3622-- the Is_Packed_Array_Impl_Type flag is set, indicating that the type 3623-- is the implementation type for a packed array, and in this case it 3624-- points to the original array type for which this is the packed 3625-- array implementation type. 3626 3627-- Original_Record_Component (Node22) 3628-- Defined in components, including discriminants. The usage depends 3629-- on whether the record is a base type and whether it is tagged. 3630-- 3631-- In base tagged types: 3632-- When the component is inherited in a record extension, it points 3633-- to the original component (the entity of the ancestor component 3634-- which is not itself inherited) otherwise it points to itself. The 3635-- backend uses this attribute to implement the automatic dereference 3636-- in the extension and to apply the transformation: 3637-- 3638-- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp 3639-- 3640-- In base untagged types: 3641-- Always points to itself except for non-girder discriminants, where 3642-- it points to the girder discriminant it renames. 3643-- 3644-- In subtypes (tagged and untagged): 3645-- Points to the component in the base type. 3646 3647-- Overlays_Constant (Flag243) 3648-- Defined in all entities. Set only for E_Constant or E_Variable for 3649-- which there is an address clause that causes the entity to overlay 3650-- a constant object. 3651 3652-- Overridden_Operation (Node26) 3653-- Defined in subprograms. For overriding operations, points to the 3654-- user-defined parent subprogram that is being overridden. Note: this 3655-- attribute uses the same field as Static_Initialization. The latter 3656-- is only defined for internal initialization procedures, for which 3657-- Overridden_Operation is irrelevant. Thus this attribute must not be 3658-- set for init_procs. 3659 3660-- Package_Instantiation (Node26) 3661-- Defined in packages and generic packages. When defined, this field 3662-- references an N_Generic_Instantiation node associated with an 3663-- instantiated package. In the case where the referenced node has 3664-- been rewritten to an N_Package_Specification, the instantiation 3665-- node is available from the Original_Node field of the package spec 3666-- node. This is currently not guaranteed to be set in all cases, but 3667-- when set, the field is used in Get_Package_Instantiation_Node as 3668-- one of the means of obtaining the instantiation node. Eventually 3669-- it should be set in all cases, including package entities associated 3670-- with formal packages. ??? 3671 3672-- Packed_Array_Impl_Type (Node23) 3673-- Defined in array types and subtypes, including the string literal 3674-- subtype case, if the corresponding type is packed (either bit packed 3675-- or packed to eliminate holes in non-contiguous enumeration type index 3676-- types). References the type used to represent the packed array, which 3677-- is either a modular type for short static arrays, or an array of 3678-- System.Unsigned. Note that in some situations (internal types, and 3679-- references to fields of variant records), it is not always possible 3680-- to construct this type in advance of its use. If this field is empty, 3681-- then the necessary type is declared on the fly for each reference to 3682-- the array. 3683 3684-- Parameter_Mode (synthesized) 3685-- Applies to formal parameter entities. This is a synonym for Ekind, 3686-- used when obtaining the formal kind of a formal parameter (the result 3687-- is one of E_[In/Out/In_Out]_Parameter). 3688 3689-- Parent_Subtype (Node19) [base type only] 3690-- Defined in E_Record_Type. Set only for derived tagged types, in which 3691-- case it points to the subtype of the parent type. This is the type 3692-- that is used as the Etype of the _parent field. 3693 3694-- Part_Of_Constituents (Elist10) 3695-- Present in abstract state and variable entities. Contains all 3696-- constituents that are subject to indicator Part_Of (both aspect and 3697-- option variants). 3698 3699-- Part_Of_References (Elist11) 3700-- Present in variable entities. Contains all references to the variable 3701-- when it is subject to pragma Part_Of. If the variable is a constituent 3702-- of a single protected/task type, the references are examined as they 3703-- must appear only within the type defintion and the corresponding body. 3704 3705-- Partial_View_Has_Unknown_Discr (Flag280) 3706-- Present in all types. Set to Indicate that the partial view of a type 3707-- has unknown discriminants. A default initialization of an object of 3708-- the type does not require an invariant check (AI12-0133). 3709 3710-- Pending_Access_Types (Elist15) 3711-- Defined in all types. Set for incomplete, private, Taft-amendment 3712-- types, and their corresponding full views. This list contains all 3713-- access types, both named and anonymous, declared between the partial 3714-- and the full view. The list is used by the finalization machinery to 3715-- ensure that the finalization masters of all pending access types are 3716-- fully initialized when the full view is frozen. 3717 3718-- Postconditions_Proc (Node14) 3719-- Defined in functions, procedures, entries, and entry families. Refers 3720-- to the entity of the _Postconditions procedure used to check contract 3721-- assertions on exit from a subprogram. 3722 3723-- Predicate_Function (synthesized) 3724-- Defined in all types. Set for types for which (Has_Predicates is True) 3725-- and for which a predicate procedure has been built that tests that the 3726-- specified predicates are True. Contains the entity for the function 3727-- which takes a single argument of the given type, and returns True if 3728-- the predicate holds and False if it does not. 3729-- 3730-- Note: the reason this is marked as a synthesized attribute is that the 3731-- way this is stored is as an element of the Subprograms_For_Type field. 3732 3733-- Predicate_Function_M (synthesized) 3734-- Defined in all types. Present only if Predicate_Function is present, 3735-- and only if the predicate function has Raise_Expression nodes. It 3736-- is the special version created for membership tests, where if one of 3737-- these raise expressions is executed, the result is to return False. 3738 3739-- Primitive_Operations (synthesized) 3740-- Defined in concurrent types, tagged record types and subtypes, tagged 3741-- private types and tagged incomplete types. For concurrent types whose 3742-- Corresponding_Record_Type (CRT) is available, returns the list of 3743-- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist. 3744-- For all the other types returns the Direct_Primitive_Operations. 3745 3746-- Prival (Node17) 3747-- Defined in private components of protected types. Refers to the entity 3748-- of the component renaming declaration generated inside protected 3749-- subprograms, entries or barrier functions. 3750 3751-- Prival_Link (Node20) 3752-- Defined in constants and variables which rename private components of 3753-- protected types. Set to the original private component. 3754 3755-- Private_Dependents (Elist18) 3756-- Defined in private (sub)types. Records the subtypes of the private 3757-- type, derivations from it, and records and arrays with components 3758-- dependent on the type. 3759-- 3760-- The subtypes are traversed when installing and deinstalling (the full 3761-- view of) a private type in order to ensure correct view of the 3762-- subtypes. 3763-- 3764-- Used in similar fashion for incomplete types: holds list of subtypes 3765-- of these incomplete types that have discriminant constraints. The 3766-- full views of these subtypes are constructed when the full view of 3767-- the incomplete type is processed. 3768 3769-- In addition, if the incomplete type is the designated type in an 3770-- access definition for an access parameter, the operation may be 3771-- a dispatching primitive operation, which is only known when the full 3772-- declaration of the type is seen. Subprograms that have such an 3773-- access parameter are also placed in the list of private_dependents. 3774 3775-- Private_View (Node22) 3776-- For each private type, three entities are allocated, the private view, 3777-- the full view, and the shadow entity. The shadow entity contains a 3778-- copy of the private view and is used for restoring the proper private 3779-- view after a region in which the full view is visible (and is copied 3780-- into the entity normally used for the private view during this period 3781-- of visibility). The Private_View field is self-referential when the 3782-- private view lives in its normal entity, but in the copy that is made 3783-- in the shadow entity, it points to the proper location in which to 3784-- restore the private view saved in the shadow. 3785 3786-- Protected_Body_Subprogram (Node11) 3787-- Defined in protected operations. References the entity for the 3788-- subprogram which implements the body of the operation. 3789 3790-- Protected_Formal (Node22) 3791-- Defined in formal parameters (in, in out and out parameters). Used 3792-- only for formals of protected operations. References corresponding 3793-- formal parameter in the unprotected version of the operation that 3794-- is created during expansion. 3795 3796-- Protection_Object (Node23) 3797-- Applies to protected entries, entry families and subprograms. Denotes 3798-- the entity which is used to rename the _object component of protected 3799-- types. 3800 3801-- Reachable (Flag49) 3802-- Defined in labels. The flag is set over the range of statements in 3803-- which a goto to that label is legal. 3804 3805-- Referenced (Flag156) 3806-- Defined in all entities. Set if the entity is referenced, except for 3807-- the case of an appearance of a simple variable that is not a renaming 3808-- as the left side of an assignment in which case Referenced_As_LHS is 3809-- set instead, or a similar appearance as an out parameter actual, in 3810-- which case Referenced_As_Out_Parameter is set. 3811 3812-- Referenced_As_LHS (Flag36): 3813-- Defined in all entities. This flag is set instead of Referenced if a 3814-- simple variable that is not a renaming appears as the left side of an 3815-- assignment. The reason we distinguish this kind of reference is that 3816-- we have a separate warning for variables that are only assigned and 3817-- never read. 3818 3819-- Referenced_As_Out_Parameter (Flag227): 3820-- Defined in all entities. This flag is set instead of Referenced if a 3821-- simple variable that is not a renaming appears as an actual for an out 3822-- formal. The reason we distinguish this kind of reference is that 3823-- we have a separate warning for variables that are only assigned and 3824-- never read, and out parameters are a special case. 3825 3826-- Refinement_Constituents (Elist8) 3827-- Present in abstract state entities. Contains all the constituents that 3828-- refine the state, in other words, all the hidden states that appear in 3829-- the constituent_list of aspect/pragma Refined_State. 3830 3831-- Register_Exception_Call (Node20) 3832-- Defined in exception entities. When an exception is declared, 3833-- a call is expanded to Register_Exception. This field points to 3834-- the expanded N_Procedure_Call_Statement node for this call. It 3835-- is used for Import/Export_Exception processing to modify the 3836-- register call to make appropriate entries in the special tables 3837-- used for handling these pragmas at runtime. 3838 3839-- Related_Array_Object (Node25) 3840-- Defined in array types and subtypes. Used only for the base type 3841-- and subtype created for an anonymous array object. Set to point 3842-- to the entity of the corresponding array object. Currently used 3843-- only for type-related error messages. 3844 3845-- Related_Expression (Node24) 3846-- Defined in variables and types. When Set for internally generated 3847-- entities, it may be used to denote the source expression whose 3848-- elaboration created the variable declaration. If set, it is used 3849-- for generating clearer messages from CodePeer. It is used on source 3850-- entities that are variables in iterator specifications, to provide 3851-- a link to the container that is the domain of iteration. This allows 3852-- for better cross-reference information when the loop modifies elements 3853-- of the container, and suppresses spurious warnings. 3854-- 3855-- Shouldn't it also be used for the same purpose in errout? It seems 3856-- odd to have two mechanisms here??? 3857 3858-- Related_Instance (Node15) 3859-- Defined in the wrapper packages created for subprogram instances. 3860-- The internal subprogram that implements the instance is inside the 3861-- wrapper package, but for debugging purposes its external symbol 3862-- must correspond to the name and scope of the related instance. 3863 3864-- Related_Type (Node27) 3865-- Defined in components, constants and variables. Set when there is an 3866-- associated dispatch table to point to entities containing primary or 3867-- secondary tags. Not set in the _tag component of record types. 3868 3869-- Relative_Deadline_Variable (Node28) [implementation base type only] 3870-- Defined in task type entities. This flag is set if a valid and 3871-- effective pragma Relative_Deadline applies to the base type. Points 3872-- to the entity for a variable that is created to hold the value given 3873-- in a Relative_Deadline pragma for a task type. 3874 3875-- Renamed_Entity (Node18) 3876-- Defined in exceptions, packages, subprograms, and generic units. Set 3877-- for entities that are defined by a renaming declaration. Denotes the 3878-- renamed entity, or transitively the ultimate renamed entity if 3879-- there is a chain of renaming declarations. Empty if no renaming. 3880 3881-- Renamed_In_Spec (Flag231) 3882-- Defined in package entities. If a package renaming occurs within 3883-- a package spec, then this flag is set on the renamed package. The 3884-- purpose is to prevent a warning about unused entities in the renamed 3885-- package. Such a warning would be inappropriate since clients of the 3886-- package can see the entities in the package via the renaming. 3887 3888-- Renamed_Object (Node18) 3889-- Defined in all objects (constants, variables, components, formal 3890-- parameters, generic formal parameters, and loop parameters). 3891-- ??? Defined in discriminants? 3892-- Set non-Empty if the object was declared by a renaming declaration, 3893-- in which case it references the tree node for the name of the renamed 3894-- object. This is only possible for the variable and constant cases. 3895-- For formal parameters, this field is used in the course of inline 3896-- expansion, to map the formals of a subprogram into the corresponding 3897-- actuals. For formals of a task entry, it denotes the local renaming 3898-- that replaces the actual within the accept statement. The field is 3899-- Empty otherwise (it is always empty for loop parameters). 3900 3901-- Renaming_Map (Uint9) 3902-- Defined in generic subprograms, generic packages, and their 3903-- instances. Also defined in the instances of the corresponding 3904-- bodies. Denotes the renaming map (generic entities => instance 3905-- entities) used to construct the instance by givin an index into 3906-- the tables used to represent these maps. See Sem_Ch12 for further 3907-- details. The maps for package instances are also used when the 3908-- instance is the actual corresponding to a formal package. 3909 3910-- Requires_Overriding (Flag213) 3911-- Defined in all subprograms and entries. Set for subprograms that 3912-- require overriding as defined by RM-2005-3.9.3(6/2). Note that this 3913-- is True only for implicitly declared subprograms; it is not set on the 3914-- parent type's subprogram. See also Is_Abstract_Subprogram. 3915 3916-- Return_Applies_To (Node8) 3917-- Defined in E_Return_Statement. Points to the entity representing 3918-- the construct to which the return statement applies, as defined in 3919-- RM-6.5(4/2). Note that a (simple) return statement within an 3920-- extended_return_statement applies to the extended_return_statement, 3921-- even though it causes the whole function to return. 3922 3923-- Return_Present (Flag54) 3924-- Defined in function and generic function entities. Set if the 3925-- function contains a return statement (used for error checking). 3926-- This flag can also be set in procedure and generic procedure 3927-- entities (for convenience in setting it), but is only tested 3928-- for the function case. 3929 3930-- Returns_By_Ref (Flag90) 3931-- Defined in function entities. Set if the function returns the result 3932-- by reference, either because its return type is a by-reference-type 3933-- or because the function explicitly uses the secondary stack. 3934 3935-- Returns_Limited_View (Flag134) 3936-- Defined in function entities. Set if the return type of the function 3937-- at the point of definition is a limited view. Used to handle the late 3938-- freezing of the function when it is called in the current semantic 3939-- unit while it is still unfrozen. 3940 3941-- Reverse_Bit_Order (Flag164) [base type only] 3942-- Defined in all record type entities. Set if entity has a Bit_Order 3943-- aspect (set by an aspect clause or attribute definition clause) that 3944-- has reversed the order of bits from the default value. When this flag 3945-- is set, a component clause must specify a set of bits entirely within 3946-- a single storage unit (Ada 95) or within a single machine scalar (see 3947-- Ada 2005 AI-133), or must occupy an integral number of storage units. 3948 3949-- Reverse_Storage_Order (Flag93) [base type only] 3950-- Defined in all record and array type entities. Set if entity has a 3951-- Scalar_Storage_Order aspect (set by an aspect clause or attribute 3952-- definition clause) that has reversed the order of storage elements 3953-- from the default value. When this flag is set for a record type, 3954-- the Bit_Order aspect must be set to the same value (either explicitly 3955-- or as the target default value). 3956 3957-- Rewritten_For_C (Flag287) 3958-- Defined on functions that return a constrained array type, when 3959-- Modify_Tree_For_C is set. Indicates that a procedure with an extra 3960-- out parameter has been created for it, and calls must be rewritten as 3961-- calls to the new procedure. 3962 3963-- RM_Size (Uint13) 3964-- Defined in all type and subtype entities. Contains the value of 3965-- type'Size as defined in the RM. See also the Esize field and 3966-- and the description on "Handling of Type'Size Values". A value 3967-- of zero in this field for a non-discrete type means that 3968-- the front end has not yet determined the size value. For the 3969-- case of a discrete type, this field is always set by the front 3970-- end and zero is a legitimate value for a type with one value. 3971 3972-- Root_Type (synthesized) 3973-- Applies to all type entities. For class-wide types, returns the root 3974-- type of the class covered by the CW type, otherwise returns the 3975-- ultimate derivation ancestor of the given type. This function 3976-- preserves the view, i.e. the Root_Type of a partial view is the 3977-- partial view of the ultimate ancestor, the Root_Type of a full view 3978-- is the full view of the ultimate ancestor. Note that this function 3979-- does not correspond exactly to the use of root type in the RM, since 3980-- in the RM root type applies to a class of types, not to a type. 3981 3982-- Scalar_Range (Node20) 3983-- Defined in all scalar types (including modular types, where the 3984-- bounds are 0 .. modulus - 1). References a node in the tree that 3985-- contains the bounds for the range. Note that this information 3986-- could be obtained by rummaging around the tree, but it is more 3987-- convenient to have it immediately at hand in the entity. The 3988-- contents of Scalar_Range can either be an N_Subtype_Indication 3989-- node (with a constraint), or a Range node, but not a simple 3990-- subtype reference (a subtype is converted into a range). 3991 3992-- Scale_Value (Uint16) 3993-- Defined in decimal fixed-point types and subtypes. Contains the scale 3994-- for the type (i.e. the value of type'Scale = the number of decimal 3995-- digits after the decimal point). 3996 3997-- Scope (Node3) 3998-- Defined in all entities. Points to the entity for the scope (block, 3999-- loop, subprogram, package etc.) in which the entity is declared. 4000-- Since this field is in the base part of the entity node, the access 4001-- routines for this field are in Sinfo. Note that for a child unit, 4002-- the Scope will be the parent package, and for a root library unit, 4003-- the Scope will be Standard. 4004 4005-- Scope_Depth (synthesized) 4006-- Applies to program units, blocks, concurrent types and entries, and 4007-- also to record types, i.e. to any entity that can appear on the scope 4008-- stack. Yields the scope depth value, which for those entities other 4009-- than records is simply the scope depth value, for record entities, it 4010-- is the Scope_Depth of the record scope. 4011 4012-- Scope_Depth_Value (Uint22) 4013-- Defined in program units, blocks, concurrent types, and entries. 4014-- Indicates the number of scopes that statically enclose the declaration 4015-- of the unit or type. Library units have a depth of zero. Note that 4016-- record types can act as scopes but do NOT have this field set (see 4017-- Scope_Depth above). 4018 4019-- Scope_Depth_Set (synthesized) 4020-- Applies to a special predicate function that returns a Boolean value 4021-- indicating whether or not the Scope_Depth field has been set. It is 4022-- needed, since returns an invalid value in this case. 4023 4024-- Sec_Stack_Needed_For_Return (Flag167) 4025-- Defined in scope entities (blocks, functions, procedures, tasks, 4026-- entries). Set to True when secondary stack is used to hold the 4027-- returned value of a function and thus should not be released on 4028-- scope exit. 4029 4030-- Shadow_Entities (List14) 4031-- Defined in package and generic package entities. Points to a list 4032-- of entities that correspond to private types. For each private type 4033-- a shadow entity is created that holds a copy of the private view. 4034-- In regions of the program where the full views of these private 4035-- entities are visible, the full view is copied into the entity that 4036-- is normally used to hold the private view, but the shadow entity 4037-- copy is unchanged. The shadow entities are then used to restore the 4038-- original private views at the end of the region. This list is a 4039-- standard format list (i.e. First (Shadow_Entities) is the first 4040-- entry and subsequent entries are obtained using Next. 4041 4042-- Shared_Var_Procs_Instance (Node22) 4043-- Defined in variables. Set non-Empty only if Is_Shared_Passive is 4044-- set, in which case this is the entity for the associated instance of 4045-- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details. 4046 4047-- Size_Check_Code (Node19) 4048-- Defined in constants and variables. Normally Empty. Set if code is 4049-- generated to check the size of the object. This field is used to 4050-- suppress this code if a subsequent address clause is encountered. 4051 4052-- Size_Clause (synthesized) 4053-- Applies to all entities. If a size clause is present in the rep 4054-- item chain for an entity then the attribute definition clause node 4055-- for the size clause is returned. Otherwise Size_Clause returns Empty 4056-- if no item is present. Usually this is only meaningful if the flag 4057-- Has_Size_Clause is set. This is because when the representation item 4058-- chain is copied for a derived type, it can inherit a size clause that 4059-- is not applicable to the entity. 4060 4061-- Size_Depends_On_Discriminant (Flag177) 4062-- Defined in all entities for types and subtypes. Indicates that the 4063-- size of the type depends on the value of one or more discriminants. 4064-- Currently, this flag is only set for arrays which have one or more 4065-- bounds depending on a discriminant value. 4066 4067-- Size_Known_At_Compile_Time (Flag92) 4068-- Defined in all entities for types and subtypes. Indicates that the 4069-- size of objects of the type is known at compile time. This flag is 4070-- used to optimize some generated code sequences, and also to enable 4071-- some error checks (e.g. disallowing component clauses on variable 4072-- length objects). It is set conservatively (i.e. if it is True, the 4073-- size is certainly known at compile time, if it is False, then the 4074-- size may or may not be known at compile time, but the code will 4075-- assume that it is not known). Note that the value may be known only 4076-- to the back end, so the fact that this flag is set does not mean that 4077-- the front end can access the value. 4078 4079-- Small_Value (Ureal21) 4080-- Defined in fixed point types. Points to the universal real for the 4081-- Small of the type, either as given in a representation clause, or 4082-- as computed (as a power of two) by the compiler. 4083 4084-- SPARK_Aux_Pragma (Node41) 4085-- Present in concurrent type, [generic] package spec and package body 4086-- entities. For concurrent types and package specs it refers to the 4087-- SPARK mode setting for the private part. This field points to the 4088-- N_Pragma node that either appears in the private part or is inherited 4089-- from the enclosing context. For package bodies, it refers to the SPARK 4090-- mode of the elaboration sequence after the BEGIN. The fields points to 4091-- the N_Pragma node that either appears in the statement sequence or is 4092-- inherited from the enclosing context. In all cases, if the pragma is 4093-- inherited, then the SPARK_Aux_Pragma_Inherited flag is set. 4094 4095-- SPARK_Aux_Pragma_Inherited (Flag266) 4096-- Present in concurrent type, [generic] package spec and package body 4097-- entities. Set if the SPARK_Aux_Pragma field points to a pragma that is 4098-- inherited, rather than a local one. 4099 4100-- SPARK_Pragma (Node40) 4101-- Present in concurrent type, entry, operator, [generic] package, 4102-- package body, [generic] subprogram, subprogram body and variable 4103-- entities. Points to the N_Pragma node that applies to the initial 4104-- declaration or body. This is either set by a local SPARK_Mode pragma 4105-- or is inherited from the context (from an outer scope for the spec 4106-- case or from the spec for the body case). In the case where it is 4107-- inherited the flag SPARK_Pragma_Inherited is set. Empty if no 4108-- SPARK_Mode pragma is applicable. 4109 4110-- SPARK_Pragma_Inherited (Flag265) 4111-- Present in concurrent type, entry, operator, [generic] package, 4112-- package body, [generic] subprogram, subprogram body and variable 4113-- entities. Set if the SPARK_Pragma attribute points to a pragma that is 4114-- inherited, rather than a local one. 4115 4116-- Spec_Entity (Node19) 4117-- Defined in package body entities. Points to corresponding package 4118-- spec entity. Also defined in subprogram body parameters in the 4119-- case where there is a separate spec, where this field references 4120-- the corresponding parameter entities in the spec. 4121 4122-- SSO_Set_High_By_Default (Flag273) [base type only] 4123-- Defined for record and array types. Set in the base type if a pragma 4124-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4125-- the record or array was declared and therefore applies to it. 4126 4127-- SSO_Set_Low_By_Default (Flag272) [base type only] 4128-- Defined for record and array types. Set in the base type if a pragma 4129-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4130-- the record or array was declared and therefore applies to it. 4131 4132-- Static_Discrete_Predicate (List25) 4133-- Defined in discrete types/subtypes with static predicates (with the 4134-- two flags Has_Predicates and Has_Static_Predicate set). Set if the 4135-- type/subtype has a static predicate. Points to a list of expression 4136-- and N_Range nodes that represent the predicate in canonical form. The 4137-- canonical form has entries sorted in ascending order, with duplicates 4138-- eliminated, and adjacent ranges coalesced, so that there is always a 4139-- gap in the values between successive entries. The entries in this list 4140-- are fully analyzed and typed with the base type of the subtype. Note 4141-- that all entries are static and have values within the subtype range. 4142 4143-- Static_Elaboration_Desired (Flag77) 4144-- Defined in library-level packages. Set by the pragma of the same 4145-- name, to indicate that static initialization must be attempted for 4146-- all types declared in the package, and that a warning must be emitted 4147-- for those types to which static initialization is not available. 4148 4149-- Static_Initialization (Node30) 4150-- Defined in initialization procedures for types whose objects can be 4151-- initialized statically. The value of this attribute is a positional 4152-- aggregate whose components are compile-time static values. Used 4153-- when available in object declarations to eliminate the call to the 4154-- initialization procedure, and to minimize elaboration code. Note: 4155-- This attribute uses the same field as Overridden_Operation, which is 4156-- irrelevant in init_procs. 4157 4158-- Static_Real_Or_String_Predicate (Node25) 4159-- Defined in real types/subtypes with static predicates (with the two 4160-- flags Has_Predicates and Has_Static_Predicate set). Set if the type 4161-- or subtype has a static predicate. Points to the return expression 4162-- of the predicate function. This is the original expression given as 4163-- the predicate except that occurrences of the type are replaced by 4164-- occurrences of the formal parameter of the predicate function (note 4165-- that the spec of this function including this formal parameter name) 4166-- is available from the Subprograms_For_Type field (it can be accessed 4167-- as Predicate_Function (typ). Also, in the case where a predicate is 4168-- inherited, the expression is of the form: 4169-- 4170-- xxxPredicate (typ2 (ent)) AND THEN expression 4171-- 4172-- where typ2 is the type from which the predicate is inherited, ent is 4173-- the entity for the current predicate function, and xxxPredicate is the 4174-- inherited predicate (from typ2). Finally for a predicate that inherits 4175-- from another predicate but does not add a predicate of its own, the 4176-- expression may consist of the above xxxPredicate call on its own. 4177 4178-- Status_Flag_Or_Transient_Decl (Node15) 4179-- Defined in variables and constants. Applies to objects that require 4180-- special treatment by the finalization machinery, such as extended 4181-- return results, IF and CASE expression results, and objects inside 4182-- N_Expression_With_Actions nodes. The attribute contains the entity 4183-- of a flag which specifies particular behavior over a region of code 4184-- or the declaration of a "hook" object. 4185-- In which case is it a flag, or a hook object??? 4186 4187-- Storage_Size_Variable (Node26) [implementation base type only] 4188-- Defined in access types and task type entities. This flag is set 4189-- if a valid and effective pragma Storage_Size applies to the base 4190-- type. Points to the entity for a variable that is created to 4191-- hold the value given in a Storage_Size pragma for an access 4192-- collection or a task type. Note that in the access type case, 4193-- this field is defined only in the root type (since derived types 4194-- share the same storage pool). 4195 4196-- Stored_Constraint (Elist23) 4197-- Defined in entities that can have discriminants (concurrent types 4198-- subtypes, record types and subtypes, private types and subtypes, 4199-- limited private types and subtypes and incomplete types). Points 4200-- to an element list containing the expressions for each of the 4201-- stored discriminants for the record (sub)type. 4202 4203-- Stores_Attribute_Old_Prefix (Flag270) 4204-- Defined in constants. Set when the constant has been generated to save 4205-- the value of attribute 'Old's prefix. 4206 4207-- Strict_Alignment (Flag145) [implementation base type only] 4208-- Defined in all type entities. Indicates that some containing part 4209-- is either aliased or tagged. This prohibits packing the object 4210-- tighter than its natural size and alignment. 4211 4212-- String_Literal_Length (Uint16) 4213-- Defined in string literal subtypes (which are created to correspond 4214-- to string literals in the program). Contains the length of the string 4215-- literal. 4216 4217-- String_Literal_Low_Bound (Node18) 4218-- Defined in string literal subtypes (which are created to correspond 4219-- to string literals in the program). Contains an expression whose 4220-- value represents the low bound of the literal. This is a copy of 4221-- the low bound of the applicable index constraint if there is one, 4222-- or a copy of the low bound of the index base type if not. 4223 4224-- Subprograms_For_Type (Node29) 4225-- Defined in all type and subprogram entities. This is used to hold 4226-- a list of subprogram entities for subprograms associated with the 4227-- type, linked through the Subprograms_For_Type field of the subprogram 4228-- entity. Basically this is a way of multiplexing the single field to 4229-- hold more than one entity (since we ran out of space in some type 4230-- entities). This is currently used for Invariant_Procedure and also 4231-- for Predicate_Function, and clients will always use the latter two 4232-- names to access entries in this list. 4233 4234-- Subps_Index (Uint24) 4235-- Present in subprogram entries. Set if the subprogram contains nested 4236-- subprograms, or is a subprogram nested within such a subprogram. Holds 4237-- the index in the Exp_Unst.Subps table for the subprogram. Note that 4238-- for the outer level subprogram, this is the starting index in the Subp 4239-- table for the entries for this subprogram. 4240 4241-- Suppress_Elaboration_Warnings (Flag148) 4242-- Defined in all entities, can be set only for subprogram entities and 4243-- for variables. If this flag is set then Sem_Elab will not generate 4244-- elaboration warnings for the subprogram or variable. Suppression of 4245-- such warnings is automatic for subprograms for which elaboration 4246-- checks are suppressed (without the need to set this flag), but the 4247-- flag is also set for various internal entities (such as init procs) 4248-- which are known not to generate any possible access before 4249-- elaboration, and it is set on variables when a warning is given to 4250-- avoid multiple elaboration warnings for the same variable. 4251 4252-- Suppress_Initialization (Flag105) 4253-- Defined in all variable, type and subtype entities. If set for a base 4254-- type, then the generation of initialization procedures is suppressed 4255-- for the type. Any other implicit initialiation (e.g. from the use of 4256-- pragma Initialize_Scalars) is also suppressed if this flag is set for 4257-- either the subtype in question, or for the base type. For variables, 4258-- this flag suppresses all implicit initialization for the object, even 4259-- if the type would normally require initialization. Set by use of 4260-- pragma Suppress_Initialization and also for internal entities where 4261-- we know that no initialization is required. For example, enumeration 4262-- image table entities set it. 4263 4264-- Suppress_Style_Checks (Flag165) 4265-- Defined in all entities. Suppresses any style checks specifically 4266-- associated with the given entity if set. 4267 4268-- Suppress_Value_Tracking_On_Call (Flag217) 4269-- Defined in all entities. Set in a scope entity if value tracking is to 4270-- be suppressed on any call within the scope. Used when an access to a 4271-- local subprogram is computed, to deal with the possibility that this 4272-- value may be passed around, and if used, may clobber a local variable. 4273 4274-- Task_Body_Procedure (Node25) 4275-- Defined in task types and subtypes. Points to the entity for the task 4276-- task body procedure (as further described in Exp_Ch9, task bodies are 4277-- expanded into procedures). A convenient function to retrieve this 4278-- field is Sem_Util.Get_Task_Body_Procedure. 4279-- 4280-- The last sentence is odd??? Why not have Task_Body_Procedure go to the 4281-- Underlying_Type of the Root_Type??? 4282 4283-- Thunk_Entity (Node31) 4284-- Defined in functions and procedures which have been classified as 4285-- Is_Thunk. Set to the target entity called by the thunk. 4286 4287-- Treat_As_Volatile (Flag41) 4288-- Defined in all type entities, and also in constants, components and 4289-- variables. Set if this entity is to be treated as volatile for code 4290-- generation purposes. Always set if Is_Volatile is set, but can also 4291-- be set as a result of situations (such as address overlays) where 4292-- the front end wishes to force volatile handling to inhibit aliasing 4293-- optimization which might be legally ok, but is undesirable. Note 4294-- that the backend always tests this flag rather than Is_Volatile. 4295-- The front end tests Is_Volatile if it is concerned with legality 4296-- checks associated with declared volatile variables, but if the test 4297-- is for the purposes of suppressing optimizations, then the front 4298-- end should test Treat_As_Volatile rather than Is_Volatile. 4299-- 4300-- Note: before testing Treat_As_Volatile, consider whether it would 4301-- be more appropriate to use Exp_Util.Is_Volatile_Reference instead, 4302-- which catches more cases of volatile references. 4303 4304-- Type_High_Bound (synthesized) 4305-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4306-- the high bound of a scalar type. The returned value is literal for a 4307-- base type, but may be an expression in the case of scalar type with 4308-- dynamic bounds. Note that in the case of a fixed point type, the high 4309-- bound is in units of small, and is an integer. 4310 4311-- Type_Low_Bound (synthesized) 4312-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4313-- the low bound of a scalar type. The returned value is literal for a 4314-- base type, but may be an expression in the case of scalar type with 4315-- dynamic bounds. Note that in the case of a fixed point type, the low 4316-- bound is in units of small, and is an integer. 4317 4318-- Underlying_Full_View (Node19) 4319-- Defined in private subtypes that are the completion of other private 4320-- types, or in private types that are derived from private subtypes. If 4321-- the full view of a private type T is derived from another private type 4322-- with discriminants Td, the full view of T is also private, and there 4323-- is no way to attach to it a further full view that would convey the 4324-- structure of T to the backend. The Underlying_Full_View is an 4325-- attribute of the full view that is a subtype of Td with the same 4326-- constraint as the declaration for T. The declaration for this subtype 4327-- is built at the point of the declaration of T, either as completion, 4328-- or as a subtype declaration where the base type is private and has a 4329-- private completion. If Td is already constrained, then its full view 4330-- can serve directly as the full view of T. 4331 4332-- Underlying_Record_View (Node28) 4333-- Defined in record types. Set for record types that are extensions of 4334-- types with unknown discriminants, and also set for internally built 4335-- underlying record views to reference its original record type. Record 4336-- types that are extensions of types with unknown discriminants do not 4337-- have a completion, but they cannot be used without having some 4338-- discriminated view at hand. This view is a record type with the same 4339-- structure, whose parent type is the full view of the parent in the 4340-- original type extension. 4341 4342-- Underlying_Type (synthesized) 4343-- Applies to all entities. This is the identity function except in the 4344-- case where it is applied to an incomplete or private type, in which 4345-- case it is the underlying type of the type declared by the completion, 4346-- or Empty if the completion has not yet been encountered and analyzed. 4347-- 4348-- Note: the reason this attribute applies to all entities, and not just 4349-- types, is to legitimize code where Underlying_Type is applied to an 4350-- entity which may or may not be a type, with the intent that if it is a 4351-- type, its underlying type is taken. 4352-- 4353-- Note also that the value of this attribute is interesting only after 4354-- the full view of the parent type has been processed. If the parent 4355-- type is declared in an enclosing package, the attribute will be non- 4356-- trivial only after the full view of the type has been analyzed. 4357 4358-- Universal_Aliasing (Flag216) [implementation base type only] 4359-- Defined in all type entities. Set to direct the back-end to avoid 4360-- any optimizations based on type-based alias analysis for this type. 4361-- Indicates that objects of this type can alias objects of any other 4362-- types, which guarantees that any objects can be referenced through 4363-- access types designating this type safely, whatever the actual type 4364-- of these objects. In other words, the effect is as though access 4365-- types designating this type were subject to No_Strict_Aliasing. 4366 4367-- Unset_Reference (Node16) 4368-- Defined in variables and out parameters. This is normally Empty. It 4369-- is set to point to an identifier that represents a reference to the 4370-- entity before any value has been set. Only the first such reference 4371-- is identified. This field is used to generate a warning message if 4372-- necessary (see Sem_Warn.Check_Unset_Reference). 4373 4374-- Used_As_Generic_Actual (Flag222) 4375-- Defined in all entities, set if the entity is used as an argument to 4376-- a generic instantiation. Used to tune certain warning messages. 4377 4378-- Uses_Lock_Free (Flag188) 4379-- Defined in protected type entities. Set to True when the Lock Free 4380-- implementation is used for the protected type. This implemenatation is 4381-- based on atomic transactions and doesn't require anymore the use of 4382-- Protection object (see System.Tasking.Protected_Objects). 4383 4384-- Uses_Sec_Stack (Flag95) 4385-- Defined in scope entities (block, entry, function, loop, procedure, 4386-- task).

Set if a pragma Warnings (Off, entity-name) 4391-- is used to suppress warnings for a given entity. It is also used by 4392-- the compiler in some situations to kill spurious warnings. Note that 4393-- clients should generally not test this flag directly, but instead 4394-- use function Has_Warnings_Off. 4395 4396-- Warnings_Off_Used (Flag236) 4397-- Defined in all entities. Can only be set if Warnings_Off is set. If 4398-- set indicates that a warning was suppressed by the Warnings_Off flag, 4399-- and Unmodified/Unreferenced would not have suppressed the warning. 4400 4401-- Warnings_Off_Used_Unmodified (Flag237) 4402-- Defined in all entities. Can only be set if Warnings_Off is set and 4403-- Has_Pragma_Unmodified is not set. If set indicates that a warning was 4404-- suppressed by the Warnings_Off status but that pragma Unmodified 4405-- would also have suppressed the warning. 4406 4407-- Warnings_Off_Used_Unreferenced (Flag238) 4408-- Defined in all entities. Can only be set if Warnings_Off is set and 4409-- Has_Pragma_Unreferenced is not set.

Used to save the value of the Is_Hidden 4415-- attribute when the limited-view is installed (Ada 2005: AI-217). 4416 4417-- Wrapped_Entity (Node27) 4418-- Defined in functions and procedures which have been classified as 4419-- Is_Primitive_Wrapper. Set to the entity being wrapper. 4420 4421--------------------------- 4422-- Renaming and Aliasing -- 4423--------------------------- 4424 4425-- Several entity attributes relate to renaming constructs, and to the use of 4426-- different names to refer to the same entity. The following is a summary of 4427-- these constructs and their prefered uses. 4428 4429-- There are three related attributes: 4430 4431-- Renamed_Entity 4432-- Renamed_Object 4433-- Alias 4434 4435-- They all overlap because they are supposed to apply to different entity 4436-- kinds. They are semantically related, and have the following intended uses: 4437 4438-- a) Renamed_Entity appplies to entities in renaming declarations that rename 4439-- an entity, so the value of the attribute IS an entity. This applies to 4440-- generic renamings, package renamings, exception renamings, and subprograms 4441-- renamings that rename a subprogram (rather than an attribute, an entry, a 4442-- protected operation, etc). 4443 4444-- b) Alias applies to overloadable entities, and the value is an overloadable 4445-- entity. so this is a subset of the previous one. We use the term Alias to 4446-- cover both renamings and inherited operations, because both cases are 4447-- handled in the same way when expanding a call. namely the Alias of a given 4448-- subprogram is the subprogram that will actually be called. 4449 4450-- Both a) and b) are set transitively, so that in fact it is not necessary to 4451-- traverse chains of renamings when looking for the original entity: it's 4452-- there in one step (this is done when analyzing renaming declarations other 4453-- than object renamings in sem_ch8). 4454 4455-- c) Renamed_Object applies to constants and variables. Given that the name 4456-- in an object renaming declaration is not necessarily an entity name, the 4457-- value of the attribute is the tree for that name, eg AR (1).Comp. The case 4458-- when that name is in fact an entity is not handled specially. This is why 4459-- in a few cases we need to use a loop to trace a chain of object renamings 4460-- where all of them happen to be entities. So: 4461 4462-- X : integer; 4463-- Y : integer renames X; -- renamed object is the identifier X 4464-- Z : integer renames Y; -- renamed object is the identifier Y 4465 4466-- The front-end does not store explicitly the fact that Z renames X. 4467 4468-------------------------------------- 4469-- Delayed Freezing and Elaboration -- 4470-------------------------------------- 4471 4472-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 4473-- freeze node, which appears later in the expanded tree. 4474 4475-- a) The flag is used by the front-end to trigger expansion actions 4476-- which include the generation of that freeze node. Typically this happens at 4477-- the end of the current compilation unit, or before the first subprogram 4478-- body is encountered in the current unit. See files freeze and exp_ch13 for 4479-- details on the actions triggered by a freeze node, which include the 4480-- construction of initialization procedures and dispatch tables. 4481 4482-- b) The flag is used by the backend to defer elaboration of the entity until 4483-- its freeze node is seen. In the absence of an explicit freeze node, an 4484-- entity is frozen (and elaborated) at the point of declaration. 4485 4486-- For object declarations, the flag is set when an address clause for the 4487-- object is encountered. Legality checks on the address expression only 4488-- take place at the freeze point of the object. 4489 4490-- Most types have an explicit freeze node, because they cannot be elaborated 4491-- until all representation and operational items that apply to them have been 4492-- analyzed. Private types and incomplete types have the flag set as well, as 4493-- do task and protected types. 4494 4495-- Implicit base types created for type derivations, as well as classwide 4496-- types created for all tagged types, have the flag set. 4497 4498-- If a subprogram has an access parameter whose designated type is incomplete 4499-- the subprogram has the flag set. 4500 4501------------------ 4502-- Access Kinds -- 4503------------------ 4504 4505-- The following entity kinds are introduced by the corresponding type 4506-- definitions: 4507 4508-- E_Access_Type, 4509-- E_General_Access_Type, 4510-- E_Access_Subprogram_Type, 4511-- E_Anonymous_Access_Subprogram_Type, 4512-- E_Access_Protected_Subprogram_Type, 4513-- E_Anonymous_Access_Protected_Subprogram_Type 4514-- E_Anonymous_Access_Type. 4515 4516-- E_Access_Subtype is for an access subtype created by a subtype 4517-- declaration. 4518 4519-- In addition, we define the kind E_Allocator_Type to label allocators. 4520-- This is because special resolution rules apply to this construct. 4521-- Eventually the constructs are labeled with the access type imposed by 4522-- the context. The backend should never see types with this Ekind. 4523 4524-- Similarly, the type E_Access_Attribute_Type is used as the initial kind 4525-- associated with an access attribute. After resolution a specific access 4526-- type will be established as determined by the context. 4527 4528-- Finally, the type Any_Access is used to label -null- during type 4529-- resolution. Any_Access is also replaced by the context type after 4530-- resolution. 4531 4532-------------------------------- 4533-- Classification of Entities -- 4534-------------------------------- 4535 4536-- The classification of program entities which follows is a refinement of 4537-- the list given in RM 3.1(1). E.g., separate entities denote subtypes of 4538-- different type classes. Ada 95 entities include class wide types, 4539-- protected types, subprogram types, generalized access types, generic 4540-- formal derived types and generic formal packages. 4541 4542-- The order chosen for these kinds allows us to classify related entities 4543-- so that they are contiguous. As a result, they do not appear in the 4544-- exact same order as their order of first appearance in the LRM (For 4545-- example, private types are listed before packages). The contiguity 4546-- allows us to define useful subtypes (see below) such as type entities, 4547-- overloaded entities, etc. 4548 4549-- Each entity (explicitly or implicitly declared) has a kind, which is 4550-- a value of the following type: 4551 4552 type Entity_Kind is ( 4553 4554 E_Void, 4555 -- The initial Ekind value for a newly created entity. Also used as the 4556 -- Ekind for Standard_Void_Type, a type entity in Standard used as a 4557 -- dummy type for the return type of a procedure (the reason we create 4558 -- this type is to share the circuits for performing overload resolution 4559 -- on calls). 4560 4561 ------------- 4562 -- Objects -- 4563 ------------- 4564 4565 E_Component, 4566 -- Components of a record declaration, private declarations of 4567 -- protected objects. 4568 4569 E_Constant, 4570 -- Constants created by an object declaration with a constant keyword 4571 4572 E_Discriminant, 4573 -- A discriminant, created by the use of a discriminant in a type 4574 -- declaration. 4575 4576 E_Loop_Parameter, 4577 -- A loop parameter created by a for loop 4578 4579 E_Variable, 4580 -- Variables created by an object declaration with no constant keyword 4581 4582 ------------------------ 4583 -- Parameter Entities -- 4584 ------------------------ 4585 4586 -- Parameters are also objects 4587 4588 E_Out_Parameter, 4589 -- An out parameter of a subprogram or entry 4590 4591 E_In_Out_Parameter, 4592 -- An in-out parameter of a subprogram or entry 4593 4594 E_In_Parameter, 4595 -- An in parameter of a subprogram or entry 4596 4597 -------------------------------- 4598 -- Generic Parameter Entities -- 4599 -------------------------------- 4600 4601 -- Generic parameters are also objects 4602 4603 E_Generic_In_Out_Parameter, 4604 -- A generic in out parameter, created by the use of a generic in out 4605 -- parameter in a generic declaration. 4606 4607 E_Generic_In_Parameter, 4608 -- A generic in parameter, created by the use of a generic in 4609 -- parameter in a generic declaration. 4610 4611 ------------------- 4612 -- Named Numbers -- 4613 ------------------- 4614 4615 E_Named_Integer, 4616 -- Named numbers created by a number declaration with an integer value 4617 4618 E_Named_Real, 4619 -- Named numbers created by a number declaration with a real value 4620 4621 ----------------------- 4622 -- Enumeration Types -- 4623 ----------------------- 4624 4625 E_Enumeration_Type, 4626 -- Enumeration types, created by an enumeration type declaration 4627 4628 E_Enumeration_Subtype, 4629 -- Enumeration subtypes, created by an explicit or implicit subtype 4630 -- declaration applied to an enumeration type or subtype. 4631 4632 ------------------- 4633 -- Numeric Types -- 4634 ------------------- 4635 4636 E_Signed_Integer_Type, 4637 -- Signed integer type, used for the anonymous base type of the 4638 -- integer subtype created by an integer type declaration. 4639 4640 E_Signed_Integer_Subtype, 4641 -- Signed integer subtype, created by either an integer subtype or 4642 -- integer type declaration (in the latter case an integer type is 4643 -- created for the base type, and this is the first named subtype). 4644 4645 E_Modular_Integer_Type, 4646 -- Modular integer type, used for the anonymous base type of the 4647 -- integer subtype created by a modular integer type declaration. 4648 4649 E_Modular_Integer_Subtype, 4650 -- Modular integer subtype, created by either an modular subtype 4651 -- or modular type declaration (in the latter case a modular type 4652 -- is created for the base type, and this is the first named subtype). 4653 4654 E_Ordinary_Fixed_Point_Type, 4655 -- Ordinary fixed type, used for the anonymous base type of the fixed 4656 -- subtype created by an ordinary fixed point type declaration. 4657 4658 E_Ordinary_Fixed_Point_Subtype, 4659 -- Ordinary fixed point subtype, created by either an ordinary fixed 4660 -- point subtype or ordinary fixed point type declaration (in the 4661 -- latter case a fixed point type is created for the base type, and 4662 -- this is the first named subtype). 4663 4664 E_Decimal_Fixed_Point_Type, 4665 -- Decimal fixed type, used for the anonymous base type of the decimal 4666 -- fixed subtype created by an ordinary fixed point type declaration. 4667 4668 E_Decimal_Fixed_Point_Subtype, 4669 -- Decimal fixed point subtype, created by either a decimal fixed point 4670 -- subtype or decimal fixed point type declaration (in the latter case 4671 -- a fixed point type is created for the base type, and this is the 4672 -- first named subtype). 4673 4674 E_Floating_Point_Type, 4675 -- Floating point type, used for the anonymous base type of the 4676 -- floating point subtype created by a floating point type declaration. 4677 4678 E_Floating_Point_Subtype, 4679 4680 -- Floating point subtype, created by either a floating point subtype 4681 -- or floating point type declaration (in the latter case a floating 4682 -- point type is created for the base type, and this is the first 4683 -- named subtype). 4684 4685 ------------------ 4686 -- Access Types -- 4687 ------------------ 4688 4689 E_Access_Type, 4690 -- An access type created by an access type declaration with no all 4691 -- keyword present.

A number of attributes appear as lists: lists of 6543 -- formals, lists of actuals, of discriminants, etc. For these, pairs 6544 -- of functions are defined, which take the form: 6545 6546 -- function First_Thing (E : Enclosing_Construct) return Thing; 6547 -- function Next_Thing (T : Thing) return Thing; 6548 6549 -- The end of iteration is always signaled by a value of Empty, so that 6550 -- loops over these chains invariably have the form: 6551 6552 -- This : Thing; 6553 -- ... 6554 -- This := First_Thing (E); 6555 6556 -- while Present (This) loop 6557 -- Do_Something_With (This); 6558 -- ... 6559 -- This := Next_Thing (This); 6560 -- end loop; 6561 6562 ----------------------------------- 6563 -- Handling of Check Suppression -- 6564 ----------------------------------- 6565 6566 -- There are three ways that checks can be suppressed: 6567 6568 -- 1. At the command line level 6569 -- 2. At the scope level. 6570 -- 3. At the entity level. 6571 6572 -- See spec of Sem in sem.ads for details of the data structures used 6573 -- to keep track of these various methods for suppressing checks. 6574 6575 ------------------------------- 6576 -- Handling of Discriminants -- 6577 ------------------------------- 6578 6579 -- During semantic processing, discriminants are separate entities which 6580 -- reflect the semantic properties and allowed usage of discriminants in 6581 -- the language. 6582 6583 -- In the case of discriminants used as bounds, the references are handled 6584 -- directly, since special processing is needed in any case. However, there 6585 -- are two circumstances in which discriminants are referenced in a quite 6586 -- general manner, like any other variables: 6587 6588 -- In initialization expressions for records. Note that the expressions 6589 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline 6590 -- pragmas are effectively in this category, since these pragmas are 6591 -- converted to initialized record fields in the Corresponding_Record_ 6592 -- Type. 6593 6594 -- In task and protected bodies, where the discriminant values may be 6595 -- referenced freely within these bodies. Discriminants can also appear 6596 -- in bounds of entry families and in defaults of operations. 6597 6598 -- In both these cases, the discriminants must be treated essentially as 6599 -- objects. The following approach is used to simplify and minimize the 6600 -- special processing that is required. 6601 6602 -- When a record type with discriminants is analyzed, semantic processing 6603 -- creates the entities for the discriminants. It also creates additional 6604 -- sets of entities called discriminals, one for each of the discriminants, 6605 -- and the Discriminal field of the discriminant entity points to this 6606 -- additional entity, which is initially created as an uninitialized 6607 -- (E_Void) entity. 6608 6609 -- During expansion of expressions, any discriminant reference is replaced 6610 -- by a reference to the corresponding discriminal. When the initialization 6611 -- procedure for the record is created (there will always be one, since 6612 -- discriminants are present, see Exp_Ch3 for further details), the 6613 -- discriminals are used as the entities for the formal parameters of 6614 -- this initialization procedure. The references to these discriminants 6615 -- have already been replaced by references to these discriminals, which 6616 -- are now the formal parameters corresponding to the required objects. 6617 6618 -- In the case of a task or protected body, the semantics similarly creates 6619 -- a set of discriminals for the discriminants of the task or protected 6620 -- type. When the procedure is created for the task body, the parameter 6621 -- passed in is a reference to the task value type, which contains the 6622 -- required discriminant values. The expander creates a set of declarations 6623 -- of the form: 6624 6625 -- discr_nameD : constant discr_type renames _task.discr_name; 6626 6627 -- where discr_nameD is the discriminal entity referenced by the task 6628 -- discriminant, and _task is the task value passed in as the parameter. 6629 -- Again, any references to discriminants in the task body have been 6630 -- replaced by the discriminal reference, which is now an object that 6631 -- contains the required value. 6632 6633 -- This approach for tasks means that two sets of discriminals are needed 6634 -- for a task type, one for the initialization procedure, and one for the 6635 -- task body. This works out nicely, since the semantics allocates one set 6636 -- for the task itself, and one set for the corresponding record. 6637 6638 -- The one bit of trickiness arises in making sure that the right set of 6639 -- discriminals is used at the right time. First the task definition is 6640 -- processed. Any references to discriminants here are replaced by the 6641 -- corresponding *task* discriminals (the record type doesn't even exist 6642 -- yet, since it is constructed as part of the expansion of the task 6643 -- declaration, which happens after the semantic processing of the task 6644 -- definition). The discriminants to be used for the corresponding record 6645 -- are created at the same time as the other discriminals, and held in the 6646 -- CR_Discriminant field of the discriminant. A use of the discriminant in 6647 -- a bound for an entry family is replaced with the CR_Discriminant because 6648 -- it controls the bound of the entry queue array which is a component of 6649 -- the corresponding record. 6650 6651 -- Just before the record initialization routine is constructed, the 6652 -- expander exchanges the task and record discriminals. This has two 6653 -- effects. First the generation of the record initialization routine 6654 -- uses the discriminals that are now on the record, which is the set 6655 -- that used to be on the task, which is what we want. 6656 6657 -- Second, a new set of (so far unused) discriminals is now on the task 6658 -- discriminants, and it is this set that will be used for expanding the 6659 -- task body, and also for the discriminal declarations at the start of 6660 -- the task body. 6661 6662 --------------------------------------------------- 6663 -- Handling of private data in protected objects -- 6664 --------------------------------------------------- 6665 6666 -- Private components in protected types pose problems similar to those 6667 -- of discriminants. Private data is visible and can be directly referenced 6668 -- from protected bodies. However, when protected entries and subprograms 6669 -- are expanded into corresponding bodies and barrier functions, private 6670 -- components lose their original context and visibility. 6671 6672 -- To remedy this side effect of expansion, private components are expanded 6673 -- into renamings called "privals", by analogy with "discriminals". 6674 6675 -- private_comp : comp_type renames _object.private_comp; 6676 6677 -- Prival declarations are inserted during the analysis of subprogram and 6678 -- entry bodies to ensure proper visibility for any subsequent expansion. 6679 -- _Object is the formal parameter of the generated corresponding body or 6680 -- a local renaming which denotes the protected object obtained from entry 6681 -- parameter _O. Privals receive minimal decoration upon creation and are 6682 -- categorized as either E_Variable for the general case or E_Constant when 6683 -- they appear in functions. 6684 6685 -- Along with the local declarations, each private component carries a 6686 -- placeholder which references the prival entity in the current body. This 6687 -- form of indirection is used to resolve name clashes of privals and other 6688 -- locally visible entities such as parameters, local objects, entry family 6689 -- indexes or identifiers used in the barrier condition. 6690 6691 -- When analyzing the statements of a protected subprogram or entry, any 6692 -- reference to a private component must resolve to the locally declared 6693 -- prival through normal visibility. In case of name conflicts (the cases 6694 -- above), the prival is marked as hidden and acts as a weakly declared 6695 -- entity. As a result, the reference points to the correct entity. When a 6696 -- private component is denoted by an expanded name (prot_type.comp for 6697 -- example), the expansion mechanism uses the placeholder of the component 6698 -- to correct the Entity and Etype of the reference. 6699 6700 ------------------- 6701 -- Type Synonyms -- 6702 ------------------- 6703 6704 -- The following type synonyms are used to tidy up the function and 6705 -- procedure declarations that follow, and also to make it possible to meet 6706 -- the requirement for the XEINFO utility that all function specs must fit 6707 -- on a single source line. 6708 6709 subtype B is Boolean; 6710 subtype C is Component_Alignment_Kind; 6711 subtype E is Entity_Id; 6712 subtype F is Float_Rep_Kind; 6713 subtype M is Mechanism_Type; 6714 subtype N is Node_Id; 6715 subtype U is Uint; 6716 subtype R is Ureal; 6717 subtype L is Elist_Id; 6718 subtype S is List_Id; 6719 6720 -------------------------------- 6721 -- Attribute Access Functions -- 6722 -------------------------------- 6723 6724 -- All attributes are manipulated through a procedural interface.
