Other 42-- attributes include sets of meanings for overloaded names, possible 43-- types for overloaded expressions, flags to indicate deferred constants, 44-- incomplete types, etc. These attributes are stored in available fields in 45-- tree nodes (i.e. fields not used by the parser, as defined by the Sinfo 46-- package specification), and accessed by means of a set of subprograms 47-- which define an abstract interface. 48 49-- There are two kinds of semantic information 50 51-- First, the tree nodes with the following Nkind values: 52 53-- N_Defining_Identifier 54-- N_Defining_Character_Literal 55-- N_Defining_Operator_Symbol 56 57-- are called Entities, and constitute the information that would often 58-- be stored separately in a symbol table. These nodes are all extended 59-- to provide extra space, and contain fields which depend on the entity 60-- kind, as defined by the contents of the Ekind field. The use of the 61-- Ekind field, and the associated fields in the entity, are defined 62-- in this package, as are the access functions to these fields. 63 64-- Second, in some cases semantic information is stored directly in other 65-- kinds of nodes, e.g. the Etype field, used to indicate the type of an 66-- expression. The access functions to these fields are defined in the 67-- Sinfo package, but their full documentation is to be found in 68-- the Einfo package specification. 69 70-- Declaration processing places information in the nodes of their defining 71-- identifiers. Name resolution places in all other occurrences of an 72-- identifier a pointer to the corresponding defining occurrence. 73 74-------------------------------- 75-- The XEINFO Utility Program -- 76-------------------------------- 77 78-- XEINFO is a utility program which automatically produces a C header file, 79-- einfo.h from the spec and body of package Einfo. It reads the input files 80-- einfo.ads and einfo.adb and produces the output file einfo.h. XEINFO is run 81-- automatically by the build scripts when you do a full bootstrap. 82 83-- In order for this utility program to operate correctly, the form of the 84-- einfo.ads and einfo.adb files must meet certain requirements and be laid 85-- out in a specific manner. 86 87-- The general form of einfo.ads is as follows: 88 89-- type declaration for type Entity_Kind 90-- subtype declarations declaring subranges of Entity_Kind 91-- subtype declarations declaring synonyms for some standard types 92-- function specs for attributes 93-- procedure specs 94-- pragma Inline declarations 95 96-- This order must be observed. There are no restrictions on the procedures, 97-- since the C header file only includes functions (The back end is not 98-- allowed to modify the generated tree). However, functions are required to 99-- have headers that fit on a single line. 100 101-- XEINFO reads and processes the function specs and the pragma Inlines. For 102-- functions that are declared as inlined, XEINFO reads the corresponding body 103-- from einfo.adb, and processes it into C code. This results in some strict 104-- restrictions on which functions can be inlined: 105 106-- The function spec must be on a single line 107 108-- There can only be a single return statement, not counting any pragma 109-- Assert statements, possibly followed by a comment. 110 111-- This single statement must either contain a function call with simple, 112-- single token arguments, or it must contain a membership test of the form 113-- a in b, where a and b are single tokens, or it must contain an equality 114-- or inequality test of single tokens, or it must contain a disjunction of 115-- the preceding constructs. 116 117-- For functions that are not inlined, there is no restriction on the body, 118-- and XEINFO generates a direct reference in the C header file which allows 119-- the C code in the backend to directly call the corresponding Ada body. 120 121---------------------------------- 122-- Handling of Type'Size Values -- 123---------------------------------- 124 125-- The Ada 95 RM contains some rather peculiar (to us) rules on the value 126-- of type'Size (see RM 13.3(55)). We have found that attempting to use 127-- these RM Size values generally, and in particular for determining the 128-- default size of objects, creates chaos, and major incompatibilities in 129-- existing code. 130 131-- The Ada 2020 RM acknowledges it and adopts GNAT's Object_Size attribute 132-- for determining the default size of objects, but stops short of applying 133-- it universally like GNAT. Indeed the notable exceptions are nonaliased 134-- stand-alone objects, which are not covered by Object_Size in Ada 2020. 135 136-- We proceed as follows, for discrete and fixed-point subtypes, we have 137-- two separate sizes for each subtype: 138 139-- The Object_Size, which is used for determining the default size of 140-- objects and components. This size value can be referred to using the 141-- Object_Size attribute. The phrase "is used" here means that it is 142-- the basis of the determination of the size. The back end is free to 143-- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone 144-- character might be stored in 32 bits on a machine with no efficient 145-- byte access instructions such as the Alpha. 146 147-- The default rules for the value of Object_Size 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 Ada 2020 RM defined attribute Object_Size uses this implementation. 162 163-- The Value_Size, which is the number of bits required to store a value 164-- of the type. This size can be referred to using the Value_Size 165-- attribute. This value is used for determining how tightly to pack 166-- records or arrays with components of this type, and also affects 167-- the semantics of unchecked conversion (unchecked conversions where 168-- the Value_Size values differ generate a warning, and are potentially 169-- target dependent). 170 171-- The default rules for the value of Value_Size are as follows: 172 173-- The Value_Size for a base subtype is the minimum number of bits 174-- required to store all values of the type (including the sign bit 175-- only if negative values are possible). 176 177-- If a subtype statically matches the first subtype, then it has 178-- by default the same Value_Size as the first subtype. This is a 179-- consequence of RM 13.1(14) ("if two subtypes statically match, 180-- then their subtype-specific aspects are the same".) 181 182-- All other subtypes have a Value_Size corresponding to the minimum 183-- number of bits required to store all values of the subtype. For 184-- dynamic bounds, it is assumed that the value can range down or up 185-- to the corresponding bound of the ancestor. 186 187-- The Ada 95 RM defined attribute Size is identified with Value_Size. 188 189-- The Size attribute may be defined for a first-named subtype. This sets 190-- the Value_Size of the first-named subtype to the given value, and the 191-- Object_Size of this first-named subtype to the given value padded up 192-- to an appropriate boundary. It is a consequence of the default rules 193-- above that this Object_Size will apply to all further subtypes. On the 194-- other hand, Value_Size is affected only for the first subtype, any 195-- dynamic subtypes obtained from it directly, and any statically matching 196-- subtypes. The Value_Size of any other static subtypes is not affected. 197 198-- Value_Size and Object_Size may be explicitly set for any subtype using 199-- an attribute definition clause. Note that the use of such a clause can 200-- cause the RM 13.1(14) rule to be violated, in Ada 95 and 2020 for the 201-- Value_Size attribute, but only in Ada 95 for the Object_Size attribute. 202-- If access types reference aliased objects whose subtypes have differing 203-- Object_Size values as a result of explicit attribute definition clauses, 204-- then it is erroneous to convert from one access subtype to the other. 205 206-- At the implementation level, the Esize field stores the Object_Size 207-- and the RM_Size field stores the Value_Size (hence the value of the 208-- Size attribute, which, as noted above, is equivalent to Value_Size). 209 210-- To get a feel for the difference, consider the following examples (note 211-- that in each case the base is short_short_integer with a size of 8): 212 213-- Object_Size Value_Size 214 215-- type x1 is range 0..5; 8 3 216 217-- type x2 is range 0..5; 218-- for x2'size use 12; 16 12 219 220-- subtype x3 is x2 range 0 .. 3; 16 2 221 222-- subtype x4 is x2'base range 0 .. 10; 8 4 223 224-- dynamic : x2'Base range -64 .. +63; 225 226-- subtype x5 is x2 range 0 .. dynamic; 16 3* 227 228-- subtype x6 is x2'base range 0 .. dynamic; 8 7* 229 230-- Note: the entries marked * are not actually specified by the Ada 95 RM, 231-- but it seems in the spirit of the RM rules to allocate the minimum number 232-- of bits known to be large enough to hold the given range of values. 233 234-- So far, so good, but GNAT has to obey the RM rules, so the question is 235-- under what conditions must the RM Size be used. The following is a list 236-- of the occasions on which the RM Size must be used: 237 238-- Component size for packed arrays or records 239-- Value of the attribute Size for a type 240-- Warning about sizes not matching for unchecked conversion 241 242-- The RM_Size field keeps track of the RM Size as needed in these 243-- three situations. 244 245-- For elementary types other than discrete and fixed-point types, the 246-- Object_Size and Value_Size are the same (and equivalent to the RM 247-- attribute Size). Only Size may be specified for such types. 248 249-- For composite types, Object_Size and Value_Size are computed from their 250-- respective value for the type of each element as well as the layout. 251 252-- All size attributes are stored as Uint values. Negative values are used to 253-- reference GCC expressions for the case of non-static sizes, as explained 254-- in Repinfo. 255 256-------------------------------------- 257-- Delayed Freezing and Elaboration -- 258-------------------------------------- 259 260-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 261-- freeze node, which appears later in the expanded tree. 262 263-- a) The flag is used by the front end to trigger expansion activities which 264-- include the generation of that freeze node. Typically this happens at the 265-- end of the current compilation unit, or before the first subprogram body is 266-- encountered in the current unit. See units Freeze and Exp_Ch13 for details 267-- on the actions triggered by a freeze node, which include the construction 268-- of initialization procedures and dispatch tables. 269 270-- b) The presence of a freeze node on an entity is used by the back end to 271-- defer elaboration of the entity until its freeze node is seen. In the 272-- absence of an explicit freeze node, an entity is frozen (and elaborated) 273-- at the point of declaration. 274 275-- For object declarations, the flag is set when an address clause for the 276-- object is encountered. Legality checks on the address expression only take 277-- place at the freeze point of the object. In Ada 2012, the flag is also set 278-- when an address aspect for the object is encountered. 279 280-- Most types have an explicit freeze node, because they cannot be elaborated 281-- until all representation and operational items that apply to them have been 282-- analyzed. Private types and incomplete types have the flag set as well, as 283-- do task and protected types. 284 285-- Implicit base types created for type derivations, as well as class-wide 286-- types created for all tagged types, have the flag set. 287 288-- If a subprogram has an access parameter whose designated type is incomplete 289-- the subprogram has the flag set. 290 291----------------------- 292-- Entity Attributes -- 293----------------------- 294 295-- This section contains a complete list of the attributes that are defined 296-- on entities. Some attributes apply to all entities, others only to certain 297-- kinds of entities. In the latter case the attribute should only be set or 298-- accessed if the Ekind field indicates an appropriate entity. 299 300-- There are two kinds of attributes that apply to entities, stored and 301-- synthesized. Stored attributes correspond to a field or flag in the entity 302-- itself. Such attributes are identified in the table below by giving the 303-- field or flag in the attribute that is used to hold the attribute value. 304-- Synthesized attributes are not stored directly, but are rather computed as 305-- needed from other attributes, or from information in the tree. These are 306-- marked "synthesized" in the table below. The stored attributes have both 307-- access functions and set procedures to set the corresponding values, while 308-- synthesized attributes have only access functions. 309 310-- Note: in the case of Node, Uint, or Elist fields, there are cases where the 311-- same physical field is used for different purposes in different entities, 312-- so these access functions should only be referenced for the class of 313-- entities in which they are defined as being present. Flags are not 314-- overlapped in this way, but nevertheless as a matter of style and 315-- abstraction (which may or may not be checked by assertions in the 316-- body), this restriction should be observed for flag fields as well. 317 318-- Note: certain of the attributes on types apply only to base types, and 319-- are so noted by the notation [base type only]. These are cases where the 320-- attribute of any subtype is the same as the attribute of the base type. 321-- The attribute can be referenced on a subtype (and automatically retrieves 322-- the value from the base type). However, it is an error to try to set the 323-- attribute on other than the base type, and if assertions are enabled, 324-- an attempt to set the attribute on a subtype will raise an assert error. 325 326-- Other attributes are noted as applying to the [implementation base type 327-- only]. These are representation attributes which must always apply to a 328-- full non-private type, and where the attributes are always on the full 329-- type. The attribute can be referenced on a subtype (and automatically 330-- retrieves the value from the implementation base type). However, it is an 331-- error to try to set the attribute on other than the implementation base 332-- type, and if assertions are enabled, an attempt to set the attribute on a 333-- subtype will raise an assert error. 334 335-- Abstract_States (Elist25) 336-- Defined for E_Package entities. Contains a list of all the abstract 337-- states declared by the related package. 338 339-- Accept_Address (Elist21) 340-- Defined in entries. If an accept has a statement sequence, then an 341-- address variable is created, which is used to hold the address of the 342-- parameters, as passed by the runtime. Accept_Address holds an element 343-- list which represents a stack of entities for these address variables. 344-- The current entry is the top of the stack, which is the last element 345-- on the list. A stack is required to handle the case of nested select 346-- statements referencing the same entry. 347 348-- Access_Disp_Table (Elist16) [implementation base type only] 349-- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged 350-- types to point to their dispatch tables. The first two entities are 351-- associated with the primary dispatch table: 1) primary dispatch table 352-- with user-defined primitives 2) primary dispatch table with predefined 353-- primitives. For each interface type covered by the tagged type we also 354-- have: 3) secondary dispatch table with thunks of primitives covering 355-- user-defined interface primitives, 4) secondary dispatch table with 356-- thunks of predefined primitives, 5) secondary dispatch table with user 357-- defined primitives, and 6) secondary dispatch table with predefined 358-- primitives. The last entity of this list is an access type declaration 359-- used to expand dispatching calls through the primary dispatch table. 360-- For an untagged record, contains No_Elist. 361 362-- Access_Disp_Table_Elab_Flag (Node30) [implementation base type only] 363-- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged 364-- types whose dispatch table elaboration must be completed at run time 365-- by the IP routine to point to its pending elaboration flag entity. 366-- This flag is needed when the elaboration of the dispatch table relies 367-- on attribute 'Position applied to an object of the type; it is used by 368-- the IP routine to avoid performing this elaboration twice. 369 370-- Access_Subprogram_Wrapper (Node41) 371-- Entity created for access_to_subprogram types that have pre/post 372-- conditions. Wrapper subprogram is created when analyzing corresponding 373-- aspect, and inherits said aspects. Body of subprogram includes code 374-- to check contracts, and a direct call to the designated subprogram. 375-- The body is part of the freeze actions for the type. 376-- The Subprogram_Type created for the Access_To_Subprogram carries the 377-- Access_Subprogram_Wrapper for use in the expansion of indirect calls. 378 379-- Activation_Record_Component (Node31) 380-- Defined for E_Variable, E_Constant, E_Loop_Parameter, and formal 381-- parameter entities. Used in Opt.Unnest_Subprogram_Mode, in which case 382-- a reference to an uplevel entity produces a corresponding component 383-- in the generated ARECnT activation record (Exp_Unst for details). 384 385-- Actual_Subtype (Node17) 386-- Defined in variables, constants, and formal parameters. This is the 387-- subtype imposed by the value of the object, as opposed to its nominal 388-- subtype, which is imposed by the declaration. The actual subtype 389-- differs from the nominal one when the latter is indefinite (as in the 390-- case of an unconstrained formal parameter, or a variable declared 391-- with an unconstrained type and an initial value). The nominal subtype 392-- is the Etype entry for the entity. The Actual_Subtype field is set 393-- only if the actual subtype differs from the nominal subtype. If the 394-- actual and nominal subtypes are the same, then the Actual_Subtype 395-- field is Empty, and Etype indicates both types. 396-- 397-- For objects, the Actual_Subtype is set only if this is a discriminated 398-- type. For arrays, the bounds of the expression are obtained and the 399-- Etype of the object is directly the constrained subtype. This is 400-- rather irregular, and the semantic checks that depend on the nominal 401-- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv). 402 403-- Address_Clause (synthesized) 404-- Applies to entries, objects and subprograms. Set if an address clause 405-- is present which references the object or subprogram and points to 406-- the N_Attribute_Definition_Clause node. Empty if no Address clause. 407-- The expression in the address clause is always a constant that is 408-- defined before the entity to which the address clause applies. 409-- Note: The backend references this field in E_Task_Type entities??? 410 411-- Address_Taken (Flag104) 412-- Defined in all entities. Set if the Address or Unrestricted_Access 413-- attribute is applied directly to the entity, i.e. the entity is the 414-- entity of the prefix of the attribute reference. Also set if the 415-- entity is the second argument of an Asm_Input or Asm_Output attribute, 416-- as the construct may entail taking its address. And also set if the 417-- entity is a subprogram and the Access or Unchecked_Access attribute is 418-- applied. Used by the backend to make sure that the address can be 419-- meaningfully taken, and also in the case of subprograms to control 420-- output of certain warnings. 421 422-- Aft_Value (synthesized) 423-- Applies to fixed-point types and subtypes. This yields the value of 424-- the Aft attribute for the type, i.e. the number of decimal digits 425-- needed after the decimal point to accommodate the delta of the type, 426-- unless the delta is greater than 0.1, in which case it is 1. 427 428-- Alias (Node18) 429-- Defined in overloadable entities (literals, subprograms, entries) and 430-- subprograms that cover a primitive operation of an abstract interface 431-- (that is, subprograms with the Interface_Alias attribute). In case of 432-- overloaded entities it points to the parent subprogram of a derived 433-- subprogram. In case of abstract interface subprograms it points to the 434-- subprogram that covers the abstract interface primitive. Also used for 435-- a subprogram renaming, where it points to the renamed subprogram. For 436-- an inherited operation (of a type extension) that is overridden in a 437-- private part, the Alias is the overriding operation. In this fashion a 438-- call from outside the package ends up executing the new body even if 439-- non-dispatching, and a call from inside calls the overriding operation 440-- because it hides the implicit one. Alias is always empty for entries. 441 442-- Alignment (Uint14) 443-- Defined in entities for types and also in constants, variables 444-- (including exceptions where it refers to the static data allocated for 445-- an exception), loop parameters, and formal parameters. This indicates 446-- the desired alignment for a type, or the actual alignment for an 447-- object. A value of zero (Uint_0) indicates that the alignment has not 448-- been set yet. The alignment can be set by an explicit alignment 449-- clause, or set by the front-end in package Layout, or set by the 450-- back-end as part of the back-end back-annotation process. The 451-- alignment field is also defined in E_Exception entities, but there it 452-- is used only by the back-end for back annotation. 453 454-- Alignment_Clause (synthesized) 455-- Applies to all entities for types and objects. If an alignment 456-- attribute definition clause is present for the entity, then this 457-- function returns the N_Attribute_Definition clause that specifies the 458-- alignment. If no alignment clause applies to the type, then the call 459-- to this function returns Empty. Note that the call can return a 460-- non-Empty value even if Has_Alignment_Clause is not set (happens with 461-- subtype and derived type declarations). Note also that a record 462-- definition clause with an (obsolescent) mod clause is converted 463-- into an attribute definition clause for this purpose. 464 465-- Anonymous_Designated_Type (Node35) 466-- Defined in variables which represent anonymous finalization masters. 467-- Contains the designated type which is being serviced by the master. 468 469-- Anonymous_Masters (Elist29) 470-- Defined in packages, subprograms, and subprogram bodies. Contains a 471-- list of anonymous finalization masters declared within the related 472-- unit. The list acts as a mapping between a master and a designated 473-- type. 474 475-- Anonymous_Object (Node30) 476-- Present in protected and task type entities. Contains the entity of 477-- the anonymous object created for a single protected or task type. 478 479-- Associated_Entity (Node37) 480-- Defined in all entities. This field is similar to Associated_Node, but 481-- applied to entities. The attribute links an entity from the generic 482-- template with its corresponding entity in the analyzed generic copy. 483-- The global references mechanism relies on the Associated_Entity to 484-- infer the context. 485 486-- Associated_Formal_Package (Node12) 487-- Defined in packages that are the actuals of formal_packages. Points 488-- to the entity in the declaration for the formal package. 489 490-- Associated_Node_For_Itype (Node8) 491-- Defined in all type and subtype entities. Set non-Empty only for 492-- Itypes. Set to point to the associated node for the Itype, i.e. 493-- the node whose elaboration generated the Itype. This is used for 494-- copying trees, to determine whether or not to copy an Itype, and 495-- also for accessibility checks on anonymous access types. This 496-- node is typically an object declaration, component declaration, 497-- type or subtype declaration. 498 499-- For an access discriminant in a type declaration, the associated_ 500-- node_for_itype is the corresponding discriminant specification. 501 502-- For an access parameter it is the enclosing subprogram declaration. 503 504-- For an access_to_protected_subprogram parameter it is the declaration 505-- of the corresponding formal parameter. 506-- 507-- Itypes have no explicit declaration, and therefore are not attached to 508-- the tree: their Parent field is always empty. The Associated_Node_For_ 509-- Itype is the only way to determine the construct that leads to the 510-- creation of a given itype entity. 511 512-- Associated_Storage_Pool (Node22) [root type only] 513-- Defined in simple and general access type entities. References the 514-- storage pool to be used for the corresponding collection. A value of 515-- Empty means that the default pool is to be used. This is defined 516-- only in the root type, since derived types must have the same pool 517-- as the parent type. 518 519-- Barrier_Function (Node12) 520-- Defined in protected entries and entry families. This is the 521-- subprogram declaration for the body of the function that returns 522-- the value of the entry barrier. 523 524-- Base_Type (synthesized) 525-- Applies to all type and subtype entities. Returns the base type of a 526-- type or subtype. The base type of a type is the type itself. The base 527-- type of a subtype is the type that it constrains (which is always 528-- a type entity, not some other subtype). Note that in the case of a 529-- subtype of a private type, it is possible for the base type attribute 530-- to return a private type, even if the subtype to which it applies is 531-- non-private. See also Implementation_Base_Type. Note: it is allowed to 532-- apply Base_Type to other than a type, in which case it simply returns 533-- the entity unchanged. 534 535-- Block_Node (Node11) 536-- Defined in block entities. Points to the identifier in the 537-- Block_Statement itself. Used when retrieving the block construct 538-- for finalization purposes, the block entity has an implicit label 539-- declaration in the enclosing declarative part, and has otherwise 540-- no direct connection in the tree with the block statement. The 541-- link is to the identifier (which is an occurrence of the entity) 542-- and not to the block_statement itself, because the statement may 543-- be rewritten, e.g. in the process of removing dead code. 544 545-- Body_Entity (Node19) 546-- Defined in package and generic package entities, points to the 547-- corresponding package body entity if one is present. 548 549-- Body_Needed_For_SAL (Flag40) 550-- Defined in package and subprogram entities that are compilation 551-- units. Indicates that the source for the body must be included 552-- when the unit is part of a standalone library. 553 554-- Body_Needed_For_Inlining (Flag299) 555-- Defined in package entities that are compilation units. Used to 556-- determine whether the body unit needs to be compiled when the 557-- package declaration appears in the list of units to inline. A body 558-- is needed for inline processing if the unit declaration contains 559-- functions that carry pragma Inline or Inline_Always, or if it 560-- contains a generic unit that requires a body. 561-- 562-- Body_References (Elist16) 563-- Defined in abstract state entities. Contains an element list of 564-- references (identifiers) that appear in a package body whose spec 565-- defines the related state. If the body refines the said state, all 566-- references on this list are illegal due to the visible refinement. 567 568-- BIP_Initialization_Call (Node29) 569-- Defined in constants and variables whose corresponding declaration 570-- is wrapped in a transient block and the inital value is provided by 571-- a build-in-place function call. Contains the relocated build-in-place 572-- call after the expansion has decoupled the call from the object. This 573-- attribute is used by the finalization machinery to insert cleanup code 574-- for all additional transient objects found in the transient block. 575 576-- C_Pass_By_Copy (Flag125) [implementation base type only] 577-- Defined in record types. Set if a pragma Convention for the record 578-- type specifies convention C_Pass_By_Copy. This convention name is 579-- treated as identical in all respects to convention C, except that 580-- if it is specified for a record type, then the C_Pass_By_Copy flag 581-- is set, and if a foreign convention subprogram has a formal of the 582-- corresponding type, then the parameter passing mechanism will be 583-- set to By_Copy (unless specifically overridden by an Import or 584-- Export pragma). 585 586-- Can_Never_Be_Null (Flag38) 587-- This flag is defined in all entities. It is set in an object which can 588-- never have a null value. Set for constant access values initialized to 589-- a non-null value. This is also set for all access parameters in Ada 83 590-- and Ada 95 modes, and for access parameters that explicitly exclude 591-- null in Ada 2005 mode. 592-- 593-- This is used to avoid unnecessary resetting of the Is_Known_Non_Null 594-- flag for such entities. In Ada 2005 mode, this is also used when 595-- determining subtype conformance of subprogram profiles to ensure 596-- that two formals have the same null-exclusion status. 597-- 598-- This is also set on some access types, e.g. the Etype of the anonymous 599-- access type of a controlling formal. 600 601-- Can_Use_Internal_Rep (Flag229) [base type only] 602-- Defined in Access_Subprogram_Kind nodes. This flag is set by the 603-- front end and used by the backend. False means that the backend 604-- must represent the type in the same way as Convention-C types (and 605-- other foreign-convention types). On many targets, this means that 606-- the backend will use dynamically generated trampolines for nested 607-- subprograms. True means that the backend can represent the type in 608-- some internal way. On the aforementioned targets, this means that the 609-- backend will not use dynamically generated trampolines. This flag 610-- must be False if Has_Foreign_Convention is True; otherwise, the front 611-- end is free to set the policy. 612-- 613-- Setting this False in all cases corresponds to the traditional back 614-- end strategy, where all access-to-subprogram types are represented the 615-- same way, independent of the Convention. For further details, see also 616-- Always_Compatible_Rep in Targparm. 617-- 618-- Efficiency note: On targets that use dynamically generated 619-- trampolines, False generally favors efficiency of top-level 620-- subprograms, whereas True generally favors efficiency of nested 621-- ones. On other targets, this flag has little or no effect on 622-- efficiency. The front end should take this into account. In 623-- particular, pragma Favor_Top_Level gives a hint that the flag 624-- should be False. 625-- 626-- Note: We considered using Convention-C for this purpose, but we need 627-- this separate flag, because Convention-C implies that in the case of 628-- P'[Unrestricted_]Access, P also have convention C. Sometimes we want 629-- to have Can_Use_Internal_Rep False for an access type, but allow P to 630-- have convention Ada. 631 632-- Chars (Name1) 633-- Defined in all entities. This field contains an entry into the names 634-- table that has the character string of the identifier, character 635-- literal or operator symbol. See Namet for further details. Note that 636-- throughout the processing of the front end, this name is the simple 637-- unqualified name. However, just before the backend is called, a call 638-- is made to Qualify_All_Entity_Names. This causes entity names to be 639-- qualified using the encoding described in exp_dbug.ads, and from that 640-- point (including post backend steps, e.g. cross-reference generation), 641-- the entities will contain the encoded qualified names. 642 643-- Checks_May_Be_Suppressed (Flag31) 644-- Defined in all entities. Set if a pragma Suppress or Unsuppress 645-- mentions the entity specifically in the second argument. If this 646-- flag is set the Global_Entity_Suppress and Local_Entity_Suppress 647-- tables must be consulted to determine if there actually is an active 648-- Suppress or Unsuppress pragma that applies to the entity. 649 650-- Class_Wide_Clone (Node38) 651-- Defined on subprogram entities. Set if the subprogram has a class-wide 652-- ore- or postcondition, and the expression contains calls to other 653-- primitive funtions of the type. Used to implement properly the 654-- semantics of inherited operations whose class-wide condition may 655-- be different from that of the ancestor (See AI012-0195). 656 657-- Class_Wide_Type (Node9) 658-- Defined in all type entities. For a tagged type or subtype, returns 659-- the corresponding implicitly declared class-wide type. For a 660-- class-wide type, returns itself. Set to Empty for untagged types. 661 662-- Cloned_Subtype (Node16) 663-- Defined in E_Record_Subtype and E_Class_Wide_Subtype entities. 664-- Each such entity can either have a Discriminant_Constraint, in 665-- which case it represents a distinct type from the base type (and 666-- will have a list of components and discriminants in the list headed by 667-- First_Entity) or else no such constraint, in which case it will be a 668-- copy of the base type. 669-- 670-- o Each element of the list in First_Entity is copied from the base 671-- type; in that case, this field is Empty. 672-- 673-- o The list in First_Entity is shared with the base type; in that 674-- case, this field points to that entity. 675-- 676-- A record or classwide subtype may also be a copy of some other 677-- subtype and share the entities in the First_Entity with that subtype. 678-- In that case, this field points to that subtype. 679-- 680-- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides 681-- this field. Note that this field ONLY appears in subtype entities, not 682-- in type entities, it is not defined, and it is an error to reference 683-- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity. 684 685-- Comes_From_Source 686-- This flag appears on all nodes, including entities, and indicates 687-- that the node was created by the scanner or parser from the original 688-- source. Thus for entities, it indicates that the entity is defined 689-- in the original source program. 690 691-- Component_Alignment (special field) [base type only] 692-- Defined in array and record entities. Contains a value of type 693-- Component_Alignment_Kind indicating the alignment of components. 694-- Set to Calign_Default normally, but can be overridden by use of 695-- the Component_Alignment pragma. Note: this field is currently 696-- stored in a non-standard way, see body for details. 697 698-- Component_Bit_Offset (Uint11) 699-- Defined in record components (E_Component, E_Discriminant). First 700-- bit position of given component, computed from the first bit and 701-- position values given in the component clause. A value of No_Uint 702-- means that the value is not yet known. The value can be set by the 703-- appearance of an explicit component clause in a record representation 704-- clause, or it can be set by the front-end in package Layout, or it can 705-- be set by the backend. By the time backend processing is completed, 706-- this field is always set. A negative value is used to represent 707-- a value which is not known at compile time, and must be computed 708-- at run-time (this happens if fields of a record have variable 709-- lengths). See package Layout for details of these values. 710-- 711-- Note: Component_Bit_Offset is redundant with respect to the fields 712-- Normalized_First_Bit and Normalized_Position, and could in principle 713-- be eliminated, but it is convenient in several situations, including 714-- use in the backend, to have this redundant field. 715 716-- Component_Clause (Node13) 717-- Defined in record components and discriminants. If a record 718-- representation clause is present for the corresponding record type a 719-- that specifies a position for the component, then the Component_Clause 720-- field of the E_Component entity points to the N_Component_Clause node. 721-- Set to Empty if no record representation clause was present, or if 722-- there was no specification for this component. 723 724-- Component_Size (Uint22) [implementation base type only] 725-- Defined in array types. It contains the component size value for 726-- the array. A value of No_Uint means that the value is not yet set. 727-- The value can be set by the use of a component size clause, or 728-- by the front end in package Layout, or by the backend. A negative 729-- value is used to represent a value which is not known at compile 730-- time, and must be computed at run-time (this happens if the type 731-- of the component has a variable length size). See package Layout 732-- for details of these values. 733 734-- Component_Type (Node20) [implementation base type only] 735-- Defined in array types and string types. References component type. 736 737-- Contains_Ignored_Ghost_Code (Flag279) 738-- Defined in blocks, packages and their bodies, subprograms and their 739-- bodies. Set if the entity contains any ignored Ghost code in the form 740-- of declaration, procedure call, assignment statement or pragma. 741 742-- Contract (Node34) 743-- Defined in constant, entry, entry family, operator, [generic] package, 744-- package body, protected unit, [generic] subprogram, subprogram body, 745-- variable, task unit, and type entities. Points to the contract of the 746-- entity, holding various assertion items and data classifiers. 747 748-- Contract_Wrapper (Node25) 749-- Defined in entry and entry family entities. Set only when the entry 750-- [family] has contract cases, preconditions, and/or postconditions. 751-- Contains the entity of a wrapper procedure which encapsulates the 752-- original entry and implements precondition/postcondition semantics. 753 754-- Corresponding_Concurrent_Type (Node18) 755-- Defined in record types that are constructed by the expander to 756-- represent task and protected types (Is_Concurrent_Record_Type flag 757-- set). Points to the entity for the corresponding task type or the 758-- protected type. 759 760-- Corresponding_Discriminant (Node19) 761-- Defined in discriminants of a derived type, when the discriminant is 762-- used to constrain a discriminant of the parent type. Points to the 763-- corresponding discriminant in the parent type. Otherwise it is Empty. 764 765-- Corresponding_Equality (Node30) 766-- Defined in function entities for implicit inequality operators. 767-- Denotes the explicit or derived equality operation that creates 768-- the implicit inequality. Note that this field is not present in 769-- other function entities, only in implicit inequality routines, 770-- where Comes_From_Source is always False. 771 772-- Corresponding_Function (Node32) 773-- Defined on procedures internally built with an extra out parameter 774-- to return a constrained array type, when Modify_Tree_For_C is set. 775-- Denotes the function that returns the constrained array type for 776-- which this procedure was built. 777 778-- Corresponding_Procedure (Node32) 779-- Defined on functions that return a constrained array type, when 780-- Modify_Tree_For_C is set. Denotes the internally built procedure 781-- with an extra out parameter created for it. 782 783-- Corresponding_Protected_Entry (Node18) 784-- Defined in subprogram bodies. Set for subprogram bodies that implement 785-- a protected type entry to point to the entity for the entry. 786 787-- Corresponding_Record_Component (Node21) 788-- Defined in components of a derived untagged record type, including 789-- discriminants. For a regular component or a girder discriminant, 790-- points to the corresponding component in the parent type. Set to 791-- Empty for a non-girder discriminant. It is used by the back end to 792-- ensure the layout of the derived type matches that of the parent 793-- type when there is no representation clause on the derived type. 794 795-- Corresponding_Record_Type (Node18) 796-- Defined in protected and task types and subtypes. References the 797-- entity for the corresponding record type constructed by the expander 798-- (see Exp_Ch9). This type is used to represent values of the task type. 799 800-- Corresponding_Remote_Type (Node22) 801-- Defined in record types that describe the fat pointer structure for 802-- Remote_Access_To_Subprogram types. References the original access 803-- to subprogram type. 804 805-- CR_Discriminant (Node23) 806-- Defined in discriminants of concurrent types. Denotes the homologous 807-- discriminant of the corresponding record type. The CR_Discriminant is 808-- created at the same time as the discriminal, and used to replace 809-- occurrences of the discriminant within the type declaration. 810 811-- Current_Use_Clause (Node27) 812-- Defined in packages and in types. For packages, denotes the use 813-- package clause currently in scope that makes the package use_visible. 814-- For types, it denotes the use_type clause that makes the operators of 815-- the type visible. Used for more precise warning messages on redundant 816-- use clauses. 817 818-- Current_Value (Node9) 819-- Defined in all object entities. Set in E_Variable, E_Constant, formal 820-- parameters and E_Loop_Parameter entities if we have trackable current 821-- values. Set non-Empty if the (constant) current value of the variable 822-- is known. This value is valid only for references from the same 823-- sequential scope as the entity. The sequential scope of an entity 824-- includes the immediate scope and any contained scopes that are package 825-- specs, package bodies, blocks (at any nesting level) or statement 826-- sequences in IF or loop statements. 827-- 828-- Another related use of this field is to record information about the 829-- value obtained from an IF or WHILE statement condition. If the IF or 830-- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ", 831-- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a 832-- Current_Value field, RELOP is one of the six relational operators, and 833-- VAL is a compile-time known value then the Current_Value field of OBJ 834-- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node 835-- of the relevant construct, and the Condition field of this can be 836-- consulted to give information about the value of OBJ. For more details 837-- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition. 838 839-- Debug_Info_Off (Flag166) 840-- Defined in all entities. Set if a pragma Suppress_Debug_Info applies 841-- to the entity, or if internal processing in the compiler determines 842-- that suppression of debug information is desirable. Note that this 843-- flag is only for use by the front end as part of the processing for 844-- determining if Needs_Debug_Info should be set. The backend should 845-- always test Needs_Debug_Info, it should never test Debug_Info_Off. 846 847-- Debug_Renaming_Link (Node25) 848-- Used to link the variable associated with a debug renaming declaration 849-- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for 850-- details of the use of this field. 851 852-- Declaration_Node (synthesized) 853-- Applies to all entities. Returns the tree node for the construct that 854-- declared the entity. Normally this is just the Parent of the entity. 855-- One exception arises with child units, where the parent of the entity 856-- is a selected component/defining program unit name. Another exception 857-- is that if the entity is an incomplete type that has been completed or 858-- a private type, then we obtain the declaration node denoted by the 859-- full type, i.e. the full type declaration node. Also note that for 860-- subprograms, this returns the {function,procedure}_specification, not 861-- the subprogram_declaration. 862 863-- Default_Aspect_Component_Value (Node19) [base type only] 864-- Defined in array types. Holds the static value specified in a 865-- Default_Component_Value aspect specification for the array type, 866-- or inherited on derivation. 867 868-- Default_Aspect_Value (Node19) [base type only] 869-- Defined in scalar types. Holds the static value specified in a 870-- Default_Value aspect specification for the type, or inherited 871-- on derivation. 872 873-- Default_Expr_Function (Node21) 874-- Defined in parameters. It holds the entity of the parameterless 875-- function that is built to evaluate the default expression if it is 876-- more complex than a simple identifier or literal. For the latter 877-- simple cases or if there is no default value, this field is Empty. 878 879-- Default_Expressions_Processed (Flag108) 880-- A flag in subprograms (functions, operators, procedures) and in 881-- entries and entry families used to indicate that default expressions 882-- have been processed and to avoid multiple calls to process the 883-- default expressions (see Freeze.Process_Default_Expressions), which 884-- would not only waste time, but also generate false error messages. 885 886-- Default_Value (Node20) 887-- Defined in formal parameters. Points to the node representing the 888-- expression for the default value for the parameter. Empty if the 889-- parameter has no default value (which is always the case for OUT 890-- and IN OUT parameters in the absence of errors). 891 892-- Delay_Cleanups (Flag114) 893-- Defined in entities that have finalization lists (subprograms 894-- blocks, and tasks). Set if there are pending generic body 895-- instantiations for the corresponding entity. If this flag is 896-- set, then generation of cleanup actions for the corresponding 897-- entity must be delayed, since the insertion of the generic body 898-- may affect cleanup generation (see Inline for further details). 899 900-- Delay_Subprogram_Descriptors (Flag50) 901-- Defined in entities for which exception subprogram descriptors 902-- are generated (subprograms, package declarations and package 903-- bodies). Defined if there are pending generic body instantiations 904-- for the corresponding entity. If this flag is set, then generation 905-- of the subprogram descriptor for the corresponding enities must 906-- be delayed, since the insertion of the generic body may add entries 907-- to the list of handlers. 908-- 909-- Note: for subprograms, Delay_Subprogram_Descriptors is set if and 910-- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a 911-- a block (in which case Delay_Subprogram_Descriptors is set for the 912-- containing subprogram). In addition Delay_Subprogram_Descriptors is 913-- set for a library level package declaration or body which contains 914-- delayed instantiations (in this case the descriptor refers to the 915-- enclosing elaboration procedure). 916 917-- Delta_Value (Ureal18) 918-- Defined in fixed and decimal types. Points to a universal real 919-- that holds value of delta for the type, as given in the declaration 920-- or as inherited by a subtype or derived type. 921 922-- Dependent_Instances (Elist8) 923-- Defined in packages that are instances. Holds list of instances 924-- of inner generics. Used to place freeze nodes for those instances 925-- after that of the current one, i.e. after the corresponding generic 926-- bodies. 927 928-- Depends_On_Private (Flag14) 929-- Defined in all type entities. Set if the type is private or if it 930-- depends on a private type. 931 932-- Derived_Type_Link (Node31) 933-- Defined in all type and subtype entities. Set in a base type if 934-- a derived type declaration is encountered which derives from 935-- this base type or one of its subtypes, and there are already 936-- primitive operations declared. In this case, it references the 937-- entity for the type declared by the derived type declaration. 938-- For example: 939-- 940-- type R is ... 941-- subtype RS is R ... 942-- ... 943-- type G is new RS ... 944-- 945-- In this case, if primitive operations have been declared for R, at 946-- the point of declaration of G, then the Derived_Type_Link of R is set 947-- to point to the entity for G. This is used to generate warnings and 948-- errors for rep clauses that appear later on for R, which might result 949-- in an unexpected (or illegal) implicit conversion operation. 950-- 951-- Note: if there is more than one such derived type, the link will point 952-- to the last one. 953 954-- Designated_Type (synthesized) 955-- Applies to access types. Returns the designated type. Differs from 956-- Directly_Designated_Type in that if the access type refers to an 957-- incomplete type, and the full type is available, then this full type 958-- is returned instead of the incomplete type. 959 960-- DIC_Procedure (synthesized) 961-- Defined in all type entities. Set for a private type and its full view 962-- when the type is subject to pragma Default_Initial_Condition (DIC), or 963-- when the type inherits a DIC pragma from a parent type. Points to the 964-- entity of a procedure which takes a single argument of the given type 965-- and verifies the assertion expression of the DIC pragma at run time. 966 967-- Note: the reason this is marked as a synthesized attribute is that the 968-- way this is stored is as an element of the Subprograms_For_Type field. 969 970-- Digits_Value (Uint17) 971-- Defined in floating point types and subtypes and decimal types and 972-- subtypes. Contains the Digits value specified in the declaration. 973 974-- Direct_Primitive_Operations (Elist10) 975-- Defined in tagged types and subtypes (including synchronized types), 976-- in tagged private types and in tagged incomplete types. Element list 977-- of entities for primitive operations of the tagged type. Not defined 978-- in untagged types. In order to follow the C++ ABI, entities of 979-- primitives that come from source must be stored in this list in the 980-- order of their occurrence in the sources. For incomplete types the 981-- list is always empty. 982-- When expansion is disabled the corresponding record type of a 983-- synchronized type is not constructed. In that case, such types 984-- carry this attribute directly. 985 986-- Directly_Designated_Type (Node20) 987-- Defined in access types. This field points to the type that is 988-- directly designated by the access type. In the case of an access 989-- type to an incomplete type, this field references the incomplete 990-- type. Directly_Designated_Type is typically used in implementing the 991-- static semantics of the language; in implementing dynamic semantics, 992-- we typically want the full view of the designated type. The function 993-- Designated_Type obtains this full type in the case of access to an 994-- incomplete type. 995 996-- Disable_Controlled (Flag253) 997-- Present in all entities. Set for a controlled type subject to aspect 998-- Disable_Controlled which evaluates to True. This flag is taken into 999-- account in synthesized attribute Is_Controlled. 1000 1001-- Discard_Names (Flag88) 1002-- Defined in types and exception entities. Set if pragma Discard_Names 1003-- applies to the entity. It is also set for declarative regions and 1004-- package specs for which a Discard_Names pragma with zero arguments 1005-- has been encountered. The purpose of setting this flag is to be able 1006-- to set the Discard_Names attribute on enumeration types declared 1007-- after the pragma within the same declarative region. This flag is 1008-- set to False if a Keep_Names pragma appears for an enumeration type. 1009 1010-- Discriminal (Node17) 1011-- Defined in discriminants (Discriminant formal: GNAT's first 1012-- coinage). The entity used as a formal parameter that corresponds 1013-- to a discriminant. See section "Handling of Discriminants" for 1014-- full details of the use of discriminals. 1015 1016-- Discriminal_Link (Node10) 1017-- Defined in E_In_Parameter or E_Constant entities. For discriminals, 1018-- points back to corresponding discriminant. For other entities, must 1019-- remain Empty. 1020 1021-- Discriminant_Checking_Func (Node20) 1022-- Defined in components. Points to the defining identifier of the 1023-- function built by the expander returns a Boolean indicating whether 1024-- the given record component exists for the current discriminant 1025-- values. 1026 1027-- Discriminant_Constraint (Elist21) 1028-- Defined in entities whose Has_Discriminants flag is set (concurrent 1029-- types, subtypes, record types and subtypes, private types and 1030-- subtypes, limited private types and subtypes and incomplete types). 1031-- It is an error to reference the Discriminant_Constraint field if 1032-- Has_Discriminants is False. 1033-- 1034-- If the Is_Constrained flag is set, Discriminant_Constraint points 1035-- to an element list containing the discriminant constraints in the 1036-- same order in which the discriminants are declared. 1037-- 1038-- If the Is_Constrained flag is not set but the discriminants of the 1039-- unconstrained type have default initial values then this field 1040-- points to an element list giving these default initial values in 1041-- the same order in which the discriminants are declared. Note that 1042-- in this case the entity cannot be a tagged record type, because 1043-- discriminants in this case cannot have defaults. 1044-- 1045-- If the entity is a tagged record implicit type, then this field is 1046-- inherited from the first subtype (so that the itype is subtype 1047-- conformant with its first subtype, which is needed when the first 1048-- subtype overrides primitive operations inherited by the implicit 1049-- base type). 1050-- 1051-- In all other cases Discriminant_Constraint contains the empty 1052-- Elist (i.e. it is initialized with a call to New_Elmt_List). 1053 1054-- Discriminant_Default_Value (Node20) 1055-- Defined in discriminants. Points to the node representing the 1056-- expression for the default value of the discriminant. Set to 1057-- Empty if the discriminant has no default value. 1058 1059-- Discriminant_Number (Uint15) 1060-- Defined in discriminants. Gives the ranking of a discriminant in 1061-- the list of discriminants of the type, i.e. a sequential integer 1062-- index starting at 1 and ranging up to number of discriminants. 1063 1064-- Dispatch_Table_Wrappers (Elist26) [implementation base type only] 1065-- Defined in E_Record_Type and E_Record_Subtype entities. Set in library 1066-- level tagged type entities if we are generating statically allocated 1067-- dispatch tables. Points to the list of dispatch table wrappers 1068-- associated with the tagged type. For an untagged record, contains 1069-- No_Elist. 1070 1071-- DTC_Entity (Node16) 1072-- Defined in function and procedure entities. Set to Empty unless 1073-- the subprogram is dispatching in which case it references the 1074-- Dispatch Table pointer Component. For regular Ada tagged this, this 1075-- is the _Tag component. For CPP_Class types and their descendants, 1076-- this points to the component entity in the record that holds the 1077-- Vtable pointer for the Vtable containing the entry referencing the 1078-- subprogram. 1079 1080-- DT_Entry_Count (Uint15) 1081-- Defined in E_Component entities. Only used for component marked 1082-- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table) 1083 1084-- DT_Offset_To_Top_Func (Node25) 1085-- Defined in E_Component entities. Only used for component marked 1086-- Is_Tag. If present it stores the Offset_To_Top function used to 1087-- provide this value in tagged types whose ancestor has discriminants. 1088 1089-- DT_Position (Uint15) 1090-- Defined in function and procedure entities which are dispatching 1091-- (should not be referenced without first checking that flag 1092-- Is_Dispatching_Operation is True). Contains the offset into 1093-- the Vtable for the entry that references the subprogram. 1094 1095-- Ekind (Ekind) 1096-- Defined in all entities. Contains a value of the enumeration type 1097-- Entity_Kind declared in a subsequent section in this spec. 1098 1099-- Elaborate_Body_Desirable (Flag210) 1100-- Defined in package entities. Set if the elaboration circuitry detects 1101-- a case where there is a package body that modifies one or more visible 1102-- entities in the package spec and there is no explicit Elaborate_Body 1103-- pragma for the package. This information is passed on to the binder, 1104-- which attempts, but does not promise, to elaborate the body as close 1105-- to the spec as possible. 1106 1107-- Elaboration_Entity (Node13) 1108-- Defined in entry, entry family, [generic] package, and subprogram 1109-- entities. This is a counter associated with the unit that is initially 1110-- set to zero, is incremented when an elaboration request for the unit 1111-- is made, and is decremented when a finalization request for the unit 1112-- is made. This is used for three purposes. First, it is used to 1113-- implement access before elaboration checks (the counter must be 1114-- non-zero to call a subprogram at elaboration time). Second, it is 1115-- used to guard against repeated execution of the elaboration code. 1116-- Third, it is used to ensure that the finalization code is executed 1117-- only after all clients have requested it. 1118-- 1119-- Note that we always allocate this counter, and set this field, but 1120-- we do not always actually use it. It is only used if it is needed 1121-- for access before elaboration use (see Elaboration_Entity_Required 1122-- flag) or if either the spec or the body has elaboration code. If 1123-- neither of these two conditions holds, then the entity is still 1124-- allocated (since we don't know early enough whether or not there 1125-- is elaboration code), but is simply not used for any purpose. 1126 1127-- Elaboration_Entity_Required (Flag174) 1128-- Defined in entry, entry family, [generic] package, and subprogram 1129-- entities. Set only if Elaboration_Entity is non-Empty to indicate that 1130-- the counter is required to be non-zero even if there is no other 1131-- elaboration code. This occurs when the Elaboration_Entity counter 1132-- is used for access before elaboration checks. If the counter is 1133-- only used to prevent multiple execution of the elaboration code, 1134-- then if there is no other elaboration code, obviously there is no 1135-- need to set the flag. 1136 1137-- Encapsulating_State (Node32) 1138-- Defined in abstract state, constant and variable entities. Contains 1139-- the entity of an ancestor state or a single concurrent type whose 1140-- refinement utilizes this item as a constituent. 1141 1142-- Enclosing_Scope (Node18) 1143-- Defined in labels. Denotes the innermost enclosing construct that 1144-- contains the label. Identical to the scope of the label, except for 1145-- labels declared in the body of an accept statement, in which case the 1146-- entry_name is the Enclosing_Scope. Used to validate goto's within 1147-- accept statements. 1148 1149-- Entry_Accepted (Flag152) 1150-- Defined in E_Entry and E_Entry_Family entities. Set if there is 1151-- at least one accept for this entry in the task body. Used to 1152-- generate warnings for missing accepts. 1153 1154-- Entry_Bodies_Array (Node19) 1155-- Defined in protected types for which Has_Entries is true. 1156-- This is the defining identifier for the array of entry body 1157-- action procedures and barrier functions used by the runtime to 1158-- execute the user code associated with each entry. 1159 1160-- Entry_Cancel_Parameter (Node23) 1161-- Defined in blocks. This only applies to a block statement for 1162-- which the Is_Asynchronous_Call_Block flag is set. It 1163-- contains the defining identifier of an object that must be 1164-- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call 1165-- call in the cleanup handler added to the block by 1166-- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean 1167-- object for task entry calls and a Communications_Block object 1168-- in the case of protected entry calls. In both cases the objects 1169-- are declared in outer scopes to this block. 1170 1171-- Entry_Component (Node11) 1172-- Defined in formal parameters (in, in out and out parameters). Used 1173-- only for formals of entries. References the corresponding component 1174-- of the entry parameter record for the entry. 1175 1176-- Entry_Formal (Node16) 1177-- Defined in components of the record built to correspond to entry 1178-- parameters. This field points from the component to the formal. It 1179-- is the back pointer corresponding to Entry_Component. 1180 1181-- Entry_Index_Constant (Node18) 1182-- Defined in an entry index parameter. This is an identifier that 1183-- eventually becomes the name of a constant representing the index 1184-- of the entry family member whose entry body is being executed. Used 1185-- to expand references to the entry index specification identifier. 1186 1187-- Entry_Index_Type (synthesized) 1188-- Applies to an entry family. Denotes Etype of the subtype indication 1189-- in the entry declaration. Used to resolve the index expression in an 1190-- accept statement for a member of the family, and in the prefix of 1191-- 'COUNT when it applies to a family member. 1192 1193-- Entry_Max_Queue_Lengths_Array (Node35) 1194-- Defined in protected types for which Has_Entries is true. Contains the 1195-- defining identifier for the array of naturals used by the runtime to 1196-- limit the queue size of each entry individually. 1197 1198-- Entry_Parameters_Type (Node15) 1199-- Defined in entries. Points to the access-to-record type that is 1200-- constructed by the expander to hold a reference to the parameter 1201-- values. This reference is manipulated (as an address) by the 1202-- tasking runtime. The designated record represents a packaging 1203-- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration 1204-- for further details). Entry_Parameters_Type is Empty if the entry 1205-- has no parameters. 1206 1207-- Enumeration_Pos (Uint11) 1208-- Defined in enumeration literals. Contains the position number 1209-- corresponding to the value of the enumeration literal. 1210 1211-- Enumeration_Rep (Uint12) 1212-- Defined in enumeration literals. Contains the representation that 1213-- corresponds to the value of the enumeration literal. Note that 1214-- this is normally the same as Enumeration_Pos except in the presence 1215-- of representation clauses, where Pos will still represent the 1216-- position of the literal within the type and Rep will have be the 1217-- value given in the representation clause. 1218 1219-- Enumeration_Rep_Expr (Node22) 1220-- Defined in enumeration literals. Points to the expression in an 1221-- associated enumeration rep clause that provides the representation 1222-- value for this literal. Empty if no enumeration rep clause for this 1223-- literal (or if rep clause does not have an entry for this literal, 1224-- an error situation). This is also used to catch duplicate entries 1225-- for the same literal. 1226 1227-- Enum_Pos_To_Rep (Node23) 1228-- Defined in enumeration types, but not enumeration subtypes. Set to 1229-- Empty unless the enumeration type has a non-standard representation, 1230-- i.e. at least one literal has a representation value different from 1231-- its position value. In this case, the alternative is the following: 1232-- if the representation is not contiguous, then Enum_Pos_To_Rep is the 1233-- entity for an array constant built when the type is frozen that maps 1234-- Pos values to corresponding Rep values, whose index type is Natural 1235-- and whose component type is the enumeration type itself; or else, if 1236-- the representation is contiguous, then Enum_Pos_To_Rep is the entity 1237-- of the index type defined above. 1238 1239-- Equivalent_Type (Node18) 1240-- Defined in class wide types and subtypes, access to protected 1241-- subprogram types, and in exception types. For a classwide type, it 1242-- is always Empty. For a class wide subtype, it points to an entity 1243-- created by the expander which gives the backend an understandable 1244-- equivalent of the class subtype with a known size (given by an 1245-- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further 1246-- details. For E_Exception_Type, this points to the record containing 1247-- the data necessary to represent exceptions (for further details, see 1248-- System.Standard_Library). For access to protected subprograms, it 1249-- denotes a record that holds pointers to the operation and to the 1250-- protected object. For remote Access_To_Subprogram types, it denotes 1251-- the record that is the fat pointer representation of an RAST. 1252 1253-- Esize (Uint12) 1254-- Defined in all types and subtypes, and also for components, constants, 1255-- and variables, including exceptions where it refers to the static data 1256-- allocated for an exception. Contains the Object_Size of the type or of 1257-- the object. A value of zero indicates that the value is not yet known. 1258-- 1259-- For the case of components where a component clause is present, the 1260-- value is the value from the component clause, which must be non- 1261-- negative (but may be zero, which is acceptable for the case of 1262-- a type with only one possible value). It is also possible for Esize 1263-- of a component to be set without a component clause defined, which 1264-- means that the component size is specified, but not the position. 1265-- See also RM_Size and the section on "Handling of Type'Size Values". 1266-- During backend processing, the value is back annotated for all zero 1267-- values, so that after the call to the backend, the value is set. 1268 1269-- Etype (Node5) 1270-- Defined in all entities. Represents the type of the entity, which 1271-- is itself another entity. For a type entity, points to the parent 1272-- type for a derived type, or if the type is not derived, points to 1273-- itself. For a subtype entity, Etype points to the base type. For 1274-- a class wide type, points to the corresponding specific type. For a 1275-- subprogram or subprogram type, Etype has the return type of a function 1276-- or is set to Standard_Void_Type to represent a procedure. The Etype 1277-- field of a package is also set to Standard_Void_Type. 1278-- 1279-- Note one obscure case: for pragma Default_Storage_Pool (null), the 1280-- Etype of the N_Null node is Empty. 1281 1282-- Extra_Accessibility (Node13) 1283-- Defined in formal parameters in the non-generic case. Normally Empty, 1284-- but if expansion is active, and a parameter is one for which a 1285-- dynamic accessibility check is required, then an extra formal of type 1286-- Natural is created (see description of field Extra_Formal), and the 1287-- Extra_Accessibility field of the formal parameter points to the entity 1288-- for this extra formal. Also defined in variables when compiling 1289-- receiving stubs. In this case, a non Empty value means that this 1290-- variable's accessibility depth has been transmitted by the caller and 1291-- must be retrieved through the entity designed by this field instead of 1292-- being computed. 1293 1294-- Extra_Accessibility_Of_Result (Node19) 1295-- Defined in (non-generic) Function, Operator, and Subprogram_Type 1296-- entities. Normally Empty, but if expansion is active, and a function 1297-- is one for which "the accessibility level of the result ... determined 1298-- by the point of call" (AI05-0234) is needed, then an extra formal of 1299-- subtype Natural is created (see description of field Extra_Formal), 1300-- and the Extra_Accessibility_Of_Result field of the function points to 1301-- the entity for this extra formal. 1302 1303-- Extra_Constrained (Node23) 1304-- Defined in formal parameters in the non-generic case. Normally Empty, 1305-- but if expansion is active and a parameter is one for which a dynamic 1306-- indication of its constrained status is required, then an extra formal 1307-- of type Boolean is created (see description of field Extra_Formal), 1308-- and the Extra_Constrained field of the formal parameter points to the 1309-- entity for this extra formal. Also defined in variables when compiling 1310-- receiving stubs. In this case, a non empty value means that this 1311-- variable's constrained status has been transmitted by the caller and 1312-- must be retrieved through the entity designed by this field instead of 1313-- being computed. 1314 1315-- Extra_Formal (Node15) 1316-- Defined in formal parameters in the non-generic case. Certain 1317-- parameters require extra implicit information to be passed (e.g. the 1318-- flag indicating if an unconstrained variant record argument is 1319-- constrained, and the accessibility level for access parameters). See 1320-- description of Extra_Constrained, Extra_Accessibility fields for 1321-- further details. Extra formal parameters are constructed to represent 1322-- these values, and chained to the end of the list of formals using the 1323-- Extra_Formal field (i.e. the Extra_Formal field of the last "real" 1324-- formal points to the first extra formal, and the Extra_Formal field of 1325-- each extra formal points to the next one, with Empty indicating the 1326-- end of the list of extra formals). Another case of Extra_Formal arises 1327-- in connection with unnesting of subprograms, where the ARECnF formal 1328-- that represents an activation record pointer is an extra formal. 1329 1330-- Extra_Formals (Node28) 1331-- Applies to subprograms, subprogram types, entries, and entry 1332-- families. Returns first extra formal of the subprogram or entry. 1333-- Returns Empty if there are no extra formals. 1334 1335-- Finalization_Master (Node23) [root type only] 1336-- Defined in access-to-controlled or access-to-class-wide types. The 1337-- field contains the entity of the finalization master which handles 1338-- dynamically allocated controlled objects referenced by the access 1339-- type. Empty for access-to-subprogram types. Empty for access types 1340-- whose designated type does not need finalization actions. 1341 1342-- Finalize_Storage_Only (Flag158) [base type only] 1343-- Defined in all types. Set on direct controlled types to which a 1344-- valid Finalize_Storage_Only pragma applies. This flag is also set on 1345-- composite types when they have at least one controlled component and 1346-- all their controlled components are Finalize_Storage_Only. It is also 1347-- inherited by type derivation except for direct controlled types where 1348-- the Finalize_Storage_Only pragma is required at each level of 1349-- derivation. 1350 1351-- Finalizer (Node28) 1352-- Applies to package declarations and bodies. Contains the entity of the 1353-- library-level program which finalizes all package-level controlled 1354-- objects. 1355 1356-- First_Component (synthesized) 1357-- Applies to incomplete, private, protected, record and task types. 1358-- Returns the first component by following the chain of declared 1359-- entities for the type a component is found (one with an Ekind of 1360-- E_Component). The discriminants are skipped. If the record is null, 1361-- then Empty is returned. 1362 1363-- First_Component_Or_Discriminant (synthesized) 1364-- Similar to First_Component, but discriminants are not skipped, so will 1365-- find the first discriminant if discriminants are present. 1366 1367-- First_Entity (Node17) 1368-- Defined in all entities which act as scopes to which a list of 1369-- associated entities is attached (blocks, class subtypes and types, 1370-- entries, functions, loops, packages, procedures, protected objects, 1371-- record types and subtypes, private types, task types and subtypes). 1372-- Points to a list of associated entities using the Next_Entity field 1373-- as a chain pointer with Empty marking the end of the list. 1374 1375-- First_Exit_Statement (Node8) 1376-- Defined in E_Loop entity. The exit statements for a loop are chained 1377-- (in reverse order of appearance) using this field to point to the 1378-- first entry in the chain (last exit statement in the loop). The 1379-- entries are chained through the Next_Exit_Statement field of the 1380-- N_Exit_Statement node with Empty marking the end of the list. 1381 1382-- First_Formal (synthesized) 1383-- Applies to subprograms and subprogram types, and also to entries 1384-- and entry families. Returns first formal of the subprogram or entry. 1385-- The formals are the first entities declared in a subprogram or in 1386-- a subprogram type (the designated type of an Access_To_Subprogram 1387-- definition) or in an entry. 1388 1389-- First_Formal_With_Extras (synthesized) 1390-- Applies to subprograms and subprogram types, and also in entries 1391-- and entry families. Returns first formal of the subprogram or entry. 1392-- Returns Empty if there are no formals. The list returned includes 1393-- all the extra formals (see description of Extra_Formals field). 1394 1395-- First_Index (Node17) 1396-- Defined in array types and subtypes. By introducing implicit subtypes 1397-- for the index constraints, we have the same structure for constrained 1398-- and unconstrained arrays, subtype marks and discrete ranges are 1399-- both represented by a subtype. This function returns the tree node 1400-- corresponding to an occurrence of the first index (NOT the entity for 1401-- the type). Subsequent indices are obtained using Next_Index. Note that 1402-- this field is defined for the case of string literal subtypes, but is 1403-- always Empty. 1404 1405-- First_Literal (Node17) 1406-- Defined in all enumeration types, including character and boolean 1407-- types. This field points to the first enumeration literal entity 1408-- for the type (i.e. it is set to First (Literals (N)) where N is 1409-- the enumeration type definition node. A special case occurs with 1410-- standard character and wide character types, where this field is 1411-- Empty, since there are no enumeration literal lists in these cases. 1412-- Note that this field is set in enumeration subtypes, but it still 1413-- points to the first literal of the base type in this case. 1414 1415-- First_Private_Entity (Node16) 1416-- Defined in all entities containing private parts (packages, protected 1417-- types and subtypes, task types and subtypes). The entities on the 1418-- entity chain are in order of declaration, so the entries for private 1419-- entities are at the end of the chain. This field points to the first 1420-- entity for the private part. It is Empty if there are no entities 1421-- declared in the private part or if there is no private part. 1422 1423-- First_Rep_Item (Node6) 1424-- Defined in all entities. If non-empty, points to a linked list of 1425-- representation pragmas nodes and representation clause nodes that 1426-- apply to the entity, linked using Next_Rep_Item, with Empty marking 1427-- the end of the list. In the case of derived types and subtypes, the 1428-- new entity inherits the chain at the point of declaration. This means 1429-- that it is possible to have multiple instances of the same kind of rep 1430-- item on the chain, in which case it is the first one that applies to 1431-- the entity. 1432-- 1433-- Note: pragmas that can apply to more than one overloadable entity, 1434-- (Convention, Interface, Inline, Inline_Always, Import, Export, 1435-- External) are never present on this chain when they apply to 1436-- overloadable entities, since it is impossible for a given pragma 1437-- to be on more than one chain at a time. 1438-- 1439-- For most representation items, the representation information is 1440-- reflected in other fields and flags in the entity. For example if a 1441-- record representation clause is present, the component entities 1442-- reflect the specified information. However, there are some items that 1443-- are only reflected in the chain. These include: 1444-- 1445-- Machine_Attribute pragma 1446-- Link_Alias pragma 1447-- Linker_Constructor pragma 1448-- Linker_Destructor pragma 1449-- Weak_External pragma 1450-- Thread_Local_Storage pragma 1451-- 1452-- If any of these items are present, then the flag Has_Gigi_Rep_Item is 1453-- set, indicating that the backend should search the chain. 1454-- 1455-- Other representation items are included in the chain so that error 1456-- messages can easily locate the relevant nodes for posting errors. 1457-- Note in particular that size clauses are defined only for this 1458-- purpose, and should only be accessed if Has_Size_Clause is set. 1459 1460-- Float_Rep (Uint10) 1461-- Defined in floating-point entities. Contains a value of type 1462-- Float_Rep_Kind. Together with the Digits_Value uniquely defines 1463-- the floating-point representation to be used. 1464 1465-- Freeze_Node (Node7) 1466-- Defined in all entities. If there is an associated freeze node for the 1467-- entity, this field references this freeze node. If no freeze node is 1468-- associated with the entity, then this field is Empty. See package 1469-- Freeze for further details. 1470 1471-- From_Limited_With (Flag159) 1472-- Defined in abtract states, package and type entities. Set to True when 1473-- the related entity is generated by the expansion of a limited with 1474-- clause. Such an entity is said to be a "shadow" - it acts as the 1475-- abstract view of a state or variable or as the incomplete view of a 1476-- type by inheriting relevant attributes from the said entity. 1477 1478-- Full_View (Node11) 1479-- Defined in all type and subtype entities and in deferred constants. 1480-- References the entity for the corresponding full type or constant 1481-- declaration. For all types other than private and incomplete types, 1482-- this field always contains Empty. If an incomplete type E1 is 1483-- completed by a private type E2 whose full type declaration entity is 1484-- E3 then the full view of E1 is E2, and the full view of E2 is E3. See 1485-- also Underlying_Type. 1486 1487-- Generic_Homonym (Node11) 1488-- Defined in generic packages. The generic homonym is the entity of 1489-- a renaming declaration inserted in every generic unit. It is used 1490-- to resolve the name of a local entity that is given by a qualified 1491-- name, when the generic entity itself is hidden by a local name. 1492 1493-- Generic_Renamings (Elist23) 1494-- Defined in package and subprogram instances. Holds mapping that 1495-- associates generic parameters with the corresponding instances, in 1496-- those cases where the instance is an entity. 1497 1498-- Handler_Records (List10) 1499-- Defined in subprogram and package entities. Points to a list of 1500-- identifiers referencing the handler record entities for the 1501-- corresponding unit. 1502 1503-- Has_Aliased_Components (Flag135) [implementation base type only] 1504-- Defined in array type entities. Indicates that the component type 1505-- of the array is aliased. Should this also be set for records to 1506-- indicate that at least one component is aliased (see processing in 1507-- Sem_Prag.Process_Atomic_Independent_Shared_Volatile???) 1508 1509-- Has_Alignment_Clause (Flag46) 1510-- Defined in all type entities and objects. Indicates if an alignment 1511-- clause has been given for the entity. If set, then Alignment_Clause 1512-- returns the N_Attribute_Definition node for the alignment attribute 1513-- definition clause. Note that it is possible for this flag to be False 1514-- even when Alignment_Clause returns non_Empty (this happens in the case 1515-- of derived type declarations). 1516 1517-- Has_All_Calls_Remote (Flag79) 1518-- Defined in all library unit entities. Set if the library unit has an 1519-- All_Calls_Remote pragma. Note that such entities must also be RCI 1520-- entities, so the flag Is_Remote_Call_Interface will always be set if 1521-- this flag is set. 1522 1523-- Has_Atomic_Components (Flag86) [implementation base type only] 1524-- Defined in all types and objects. Set only for an array type or 1525-- an array object if a valid pragma Atomic_Components applies to the 1526-- type or object. Note that in the case of an object, this flag is 1527-- only set on the object if there was an explicit pragma for the 1528-- object. In other words, the proper test for whether an object has 1529-- atomic components is to see if either the object or its base type 1530-- has this flag set. Note that in the case of a type, the pragma will 1531-- be chained to the rep item chain of the first subtype in the usual 1532-- manner. 1533 1534-- Has_Attach_Handler (synthesized) 1535-- Applies to record types that are constructed by the expander to 1536-- represent protected types. Returns True if there is at least one 1537-- Attach_Handler pragma in the corresponding specification. 1538 1539-- Has_Biased_Representation (Flag139) 1540-- Defined in discrete types (where it applies to the type'size value), 1541-- and to objects (both stand-alone and components), where it applies to 1542-- the size of the object from a size or record component clause. In 1543-- all cases it indicates that the size in question is smaller than 1544-- would normally be required, but that the size requirement can be 1545-- satisfied by using a biased representation, in which stored values 1546-- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to 1547-- reduce the required size. For example, a type with a range of 1..2 1548-- takes one bit, using 0 to represent 1 and 1 to represent 2. 1549-- 1550-- Note that in the object and component cases, the flag is only set if 1551-- the type is unbiased, but the object specifies a smaller size than the 1552-- size of the type, forcing biased representation for the object, but 1553-- the subtype is still an unbiased type. 1554 1555-- Has_Completion (Flag26) 1556-- Defined in all entities that require a completion (functions, 1557-- procedures, private types, limited private types, incomplete types, 1558-- constants and packages that require a body). The flag is set if the 1559-- completion has been encountered and analyzed. 1560 1561-- Has_Completion_In_Body (Flag71) 1562-- Defined in all entities for types and subtypes. Set only in "Taft 1563-- amendment types" (incomplete types whose full declaration appears in 1564-- the package body). 1565 1566-- Has_Complex_Representation (Flag140) [implementation base type only] 1567-- Defined in record types. Set only for a base type to which a valid 1568-- pragma Complex_Representation applies. 1569 1570-- Has_Component_Size_Clause (Flag68) [implementation base type only] 1571-- Defined in all type entities. Set if a component size clause is 1572-- Defined for the given type. Note that this flag can be False even 1573-- if Component_Size is non-zero (happens in the case of derived types). 1574 1575-- Has_Constrained_Partial_View (Flag187) [base type only] 1576-- Defined in private type and their completions, when the private 1577-- type has no discriminants and the full view has discriminants with 1578-- defaults. In Ada 2005 heap-allocated objects of such types are not 1579-- constrained, and can change their discriminants with full assignment. 1580-- 1581-- Ada 2012 has an additional rule (3.3. (23/10.3)) concerning objects 1582-- declared in a generic package body. Objects whose type is an untagged 1583-- generic formal private type are considered to have a constrained 1584-- partial view. The predicate Object_Type_Has_Constrained_Partial_View 1585-- in sem_aux is used to test for this case. 1586 1587-- Has_Contiguous_Rep (Flag181) 1588-- Defined in enumeration types. Set if the type has a representation 1589-- clause whose entries are successive integers. 1590 1591-- Has_Controlled_Component (Flag43) [base type only] 1592-- Defined in all type and subtype entities. Set only for composite type 1593-- entities which contain a component that either is a controlled type, 1594-- or itself contains controlled component (i.e. either Is_Controlled or 1595-- Has_Controlled_Component is set for at least one component). 1596 1597-- Has_Controlling_Result (Flag98) 1598-- Defined in E_Function entities. Set if the function is a primitive 1599-- function of a tagged type which can dispatch on result. 1600 1601-- Has_Convention_Pragma (Flag119) 1602-- Defined in all entities. Set for an entity for which a valid pragma 1603-- Convention, Import, or Export has been given. Used to prevent more 1604-- than one such pragma appearing for a given entity (RM B.1(45)). 1605 1606-- Has_Default_Aspect (Flag39) [base type only] 1607-- Defined in entities for types and subtypes, set for scalar types with 1608-- a Default_Value aspect and array types with a Default_Component_Value 1609-- aspect. If this flag is set, then a corresponding aspect specification 1610-- node will be present on the rep item chain for the entity. For a 1611-- derived type that inherits a default from its ancestor, the default 1612-- value is set, but it may be overridden by an aspect declaration on 1613-- type derivation. 1614 1615-- Has_Delayed_Aspects (Flag200) 1616-- Defined in all entities. Set if the Rep_Item chain for the entity has 1617-- one or more N_Aspect_Definition nodes chained which are not to be 1618-- evaluated till the freeze point. The aspect definition expression 1619-- clause has been preanalyzed to get visibility at the point of use, 1620-- but no other action has been taken. 1621 1622-- Has_Delayed_Freeze (Flag18) 1623-- Defined in all entities. Set to indicate that an explicit freeze 1624-- node must be generated for the entity at its freezing point. See 1625-- separate section ("Delayed Freezing and Elaboration") for details. 1626 1627-- Has_Delayed_Rep_Aspects (Flag261) 1628-- Defined in all types and subtypes. This flag is set if there is at 1629-- least one aspect for a representation characteristic that has to be 1630-- delayed and is one of the characteristics that may be inherited by 1631-- types derived from this type if not overridden. If this flag is set, 1632-- then types derived from this type have May_Inherit_Delayed_Rep_Aspects 1633-- set, signalling that Freeze.Inherit_Delayed_Rep_Aspects must be called 1634-- at the freeze point of the derived type. 1635 1636-- Has_DIC (synthesized) 1637-- Defined in all type entities. Set for a private type and its full view 1638-- when the type is subject to pragma Default_Initial_Condition (DIC), or 1639-- when the type inherits a DIC pragma from a parent type. 1640 1641-- Has_Discriminants (Flag5) 1642-- Defined in all types and subtypes. For types that are allowed to have 1643-- discriminants (record types and subtypes, task types and subtypes, 1644-- protected types and subtypes, private types, limited private types, 1645-- and incomplete types), indicates if the corresponding type or subtype 1646-- has a known discriminant part. Always false for all other types. 1647 1648-- Has_Dispatch_Table (Flag220) 1649-- Defined in E_Record_Types that are tagged. Set to indicate that the 1650-- corresponding dispatch table is already built. This flag is used to 1651-- avoid duplicate construction of library level dispatch tables (because 1652-- the declaration of library level objects cause premature construction 1653-- of the table); otherwise the code that builds the table is added at 1654-- the end of the list of declarations of the package. 1655 1656-- Has_Dynamic_Predicate_Aspect (Flag258) 1657-- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect 1658-- was explicitly applied to the type. Generally we treat predicates as 1659-- static if possible, regardless of whether they are specified using 1660-- Predicate, Static_Predicate, or Dynamic_Predicate. And if a predicate 1661-- can be treated as static (i.e. its expression is predicate-static), 1662-- then the flag Has_Static_Predicate will be set True. But there are 1663-- cases where legality is affected by the presence of an explicit 1664-- Dynamic_Predicate aspect. For example, even if a predicate looks 1665-- static, you can't use it in a case statement if there is an explicit 1666-- Dynamic_Predicate aspect specified. So test Has_Static_Predicate if 1667-- you just want to know if the predicate can be evaluated statically, 1668-- but test Has_Dynamic_Predicate_Aspect to enforce legality rules about 1669-- the use of dynamic predicates. 1670 1671-- Has_Entries (synthesized) 1672-- Applies to concurrent types. True if any entries are declared 1673-- within the task or protected definition for the type. 1674 1675-- Has_Enumeration_Rep_Clause (Flag66) 1676-- Defined in enumeration types. Set if an enumeration representation 1677-- clause has been given for this enumeration type. Used to prevent more 1678-- than one enumeration representation clause for a given type. Note 1679-- that this does not imply a representation with holes, since the rep 1680-- clause may merely confirm the default 0..N representation. 1681 1682-- Has_Exit (Flag47) 1683-- Defined in loop entities. Set if the loop contains an exit statement. 1684 1685-- Has_Expanded_Contract (Flag240) 1686-- Defined in functions, procedures, entries, and entry families. Set 1687-- when a subprogram has a N_Contract node that has been expanded. The 1688-- flag prevents double expansion of a contract when a construct is 1689-- rewritten into something else and subsequently reanalyzed/expanded. 1690 1691-- Has_Foreign_Convention (synthesized) 1692-- Applies to all entities. Determines if the Convention for the entity 1693-- is a foreign convention, i.e. non-native: other than Convention_Ada, 1694-- Convention_Intrinsic, Convention_Entry, Convention_Protected, 1695-- Convention_Stubbed and Convention_Ada_Pass_By_(Copy,Reference). 1696 1697-- Has_Forward_Instantiation (Flag175) 1698-- Defined in package entities. Set for packages that instantiate local 1699-- generic entities before the corresponding generic body has been seen. 1700-- If a package has a forward instantiation, we cannot inline subprograms 1701-- appearing in the same package because the placement requirements of 1702-- the instance will conflict with the linear elaboration of front-end 1703-- inlining. 1704 1705-- Has_Fully_Qualified_Name (Flag173) 1706-- Defined in all entities. Set if the name in the Chars field has been 1707-- replaced by the fully qualified name, as used for debug output. See 1708-- Exp_Dbug for a full description of the use of this flag and also the 1709-- related flag Has_Qualified_Name. 1710 1711-- Has_Gigi_Rep_Item (Flag82) 1712-- Defined in all entities. Set if the rep item chain (referenced by 1713-- First_Rep_Item and linked through the Next_Rep_Item chain) contains a 1714-- representation item that needs to be specially processed by the back 1715-- end, i.e. one of the following items: 1716-- 1717-- Machine_Attribute pragma 1718-- Linker_Alias pragma 1719-- Linker_Constructor pragma 1720-- Linker_Destructor pragma 1721-- Weak_External pragma 1722-- Thread_Local_Storage pragma 1723-- 1724-- If this flag is set, then the backend should scan the rep item chain 1725-- to process any of these items that appear. At least one such item will 1726-- be present. 1727-- 1728-- Has_Homonym (Flag56) 1729-- Defined in all entities. Set if an entity has a homonym in the same 1730-- scope. Used by the backend to generate unique names for all entities. 1731 1732-- Has_Implicit_Dereference (Flag251) 1733-- Defined in types and discriminants. Set if the type has an aspect 1734-- Implicit_Dereference. Set also on the discriminant named in the aspect 1735-- clause, to simplify type resolution. 1736 1737-- Has_Independent_Components (Flag34) [implementation base type only] 1738-- Defined in all types and objects. Set only for a record type or an 1739-- array type or array object if a valid pragma Independent_Components 1740-- applies to the type or object. Note that in the case of an object, 1741-- this flag is only set on the object if there was an explicit pragma 1742-- for the object. In other words, the proper test for whether an object 1743-- has independent components is to see if either the object or its base 1744-- type has this flag set. Note that in the case of a type, the pragma 1745-- will be chained to the rep item chain of the first subtype in the 1746-- usual manner. Also set if a pragma Has_Atomic_Components or pragma 1747-- Has_Aliased_Components applies to the type or object. 1748 1749-- Has_Inheritable_Invariants (Flag248) [base type only] 1750-- Defined in all type entities. Set on private types and interface types 1751-- which define at least one class-wide invariant. Such invariants must 1752-- be inherited by derived types. The flag is also set on the full view 1753-- of a private type for completeness. 1754 1755-- Has_Inherited_DIC (Flag133) [base type only] 1756-- Defined in all type entities. Set for a derived type which inherits 1757-- pragma Default_Initial_Condition from a parent type. 1758 1759-- Has_Inherited_Invariants (Flag291) [base type only] 1760-- Defined in all type entities. Set on private extensions and derived 1761-- types which inherit at least one class-wide invariant from a parent or 1762-- an interface type. The flag is also set on the full view of a private 1763-- extension for completeness. 1764 1765-- Has_Initial_Value (Flag219) 1766-- Defined in entities for variables and out parameters. Set if there 1767-- is an explicit initial value expression in the declaration of the 1768-- variable. Note that this is set only if this initial value is 1769-- explicit, it is not set for the case of implicit initialization 1770-- of access types or controlled types. Always set to False for out 1771-- parameters. Also defined in entities for in and in-out parameters, 1772-- but always false in these cases. 1773 1774-- Has_Interrupt_Handler (synthesized) 1775-- Applies to all protected type entities. Set if the protected type 1776-- definition contains at least one procedure to which a pragma 1777-- Interrupt_Handler applies. 1778 1779-- Has_Invariants (synthesized) 1780-- Defined in all type entities. True if the type defines at least one 1781-- invariant of its own or inherits at least one class-wide invariant 1782-- from a parent type or an interface. 1783 1784-- Has_Limited_View (synth) 1785-- Defined in all entities. True for non-generic package entities that 1786-- are non-instances and their Limited_View attribute is present. 1787 1788-- Has_Loop_Entry_Attributes (Flag260) 1789-- Defined in E_Loop entities. Set when the loop is subject to at least 1790-- one attribute 'Loop_Entry. The flag also implies that the loop has 1791-- already been transformed. See Expand_Loop_Entry_Attribute for details. 1792 1793-- Has_Machine_Radix_Clause (Flag83) 1794-- Defined in decimal types and subtypes, set if a Machine_Radix 1795-- representation clause is present. This flag is used to detect 1796-- the error of multiple machine radix clauses for a single type. 1797 1798-- Has_Master_Entity (Flag21) 1799-- Defined in entities that can appear in the scope stack (see spec 1800-- of Sem). It is set if a task master entity (_master) has been 1801-- declared and initialized in the corresponding scope. 1802 1803-- Has_Missing_Return (Flag142) 1804-- Defined in functions and generic functions. Set if there is one or 1805-- more missing return statements in the function. This is used to 1806-- control wrapping of the body in Exp_Ch6 to ensure that the program 1807-- error exception is correctly raised in this case at run time. 1808 1809-- Has_Nested_Block_With_Handler (Flag101) 1810-- Defined in scope entities. Set if there is a nested block within the 1811-- scope that has an exception handler and the two scopes are in the 1812-- same procedure. This is used by the backend for controlling certain 1813-- optimizations to ensure that they are consistent with exceptions. 1814-- See documentation in backend for further details. 1815 1816-- Has_Nested_Subprogram (Flag282) 1817-- Defined in subprogram entities. Set for a subprogram which contains at 1818-- least one nested subprogram. 1819 1820-- Has_Non_Limited_View (synth) 1821-- Defined in E_Incomplete_Type, E_Incomplete_Subtype, E_Class_Wide_Type, 1822-- E_Abstract_State entities. True if their Non_Limited_View attribute 1823-- is present. 1824 1825-- Has_Non_Null_Abstract_State (synth) 1826-- Defined in package entities. True if the package is subject to a non- 1827-- null Abstract_State aspect/pragma. 1828 1829-- Has_Non_Null_Visible_Refinement (synth) 1830-- Defined in E_Abstract_State entities. True if the state has a visible 1831-- refinement of at least one variable or state constituent as expressed 1832-- in aspect/pragma Refined_State. 1833 1834-- Has_Non_Standard_Rep (Flag75) [implementation base type only] 1835-- Defined in all type entities. Set when some representation clause 1836-- or pragma causes the representation of the item to be significantly 1837-- modified. In this category are changes of small or radix for a 1838-- fixed-point type, change of component size for an array, and record 1839-- or enumeration representation clauses, as well as packed pragmas. 1840-- All other representation clauses (e.g. Size and Alignment clauses) 1841-- are not considered to be significant since they do not affect 1842-- stored bit patterns. 1843 1844-- Has_Null_Abstract_State (synth) 1845-- Defined in package entities. True if the package is subject to a null 1846-- Abstract_State aspect/pragma. 1847 1848-- Has_Null_Visible_Refinement (synth) 1849-- Defined in E_Abstract_State entities. True if the state has a visible 1850-- null refinement as expressed in aspect/pragma Refined_State. 1851 1852-- Has_Object_Size_Clause (Flag172) 1853-- Defined in entities for types and subtypes. Set if an Object_Size 1854-- clause has been processed for the type. Used to prevent multiple 1855-- Object_Size clauses for a given entity. 1856 1857-- Has_Out_Or_In_Out_Parameter (Flag110) 1858-- Present in subprograms, generic subprograms, entries, and entry 1859-- families. Set if they have at least one OUT or IN OUT parameter 1860-- (allowed for functions only in Ada 2012). 1861 1862-- Has_Own_DIC (Flag3) [base type only] 1863-- Defined in all type entities. Set for a private type and its full view 1864-- (and its underlying full view, if the full view is itself private) 1865-- when the type is subject to pragma Default_Initial_Condition. 1866 1867-- Has_Own_Invariants (Flag232) [base type only] 1868-- Defined in all type entities. Set on any type that defines at least 1869-- one invariant of its own. 1870 1871-- Note: this flag is set on both partial and full view of types to which 1872-- an Invariant pragma or aspect applies, and on the underlying full view 1873-- if the full view is private. 1874 1875-- Has_Partial_Visible_Refinement (Flag296) 1876-- Defined in E_Abstract_State entities. Set when a state has at least 1877-- one refinement constituent subject to indicator Part_Of, and analysis 1878-- is in the region between the declaration of the first constituent for 1879-- this abstract state (in the private part of the package) and the end 1880-- of the package spec or body with visibility over this private part 1881-- (which includes the package itself and its child packages). 1882 1883-- Has_Per_Object_Constraint (Flag154) 1884-- Defined in E_Component entities. Set if the subtype of the component 1885-- has a per object constraint. Per object constraints result from the 1886-- following situations : 1887-- 1888-- 1. N_Attribute_Reference - when the prefix is the enclosing type and 1889-- the attribute is Access. 1890-- 2. N_Discriminant_Association - when the expression uses the 1891-- discriminant of the enclosing type. 1892-- 3. N_Index_Or_Discriminant_Constraint - when at least one of the 1893-- individual constraints is a per object constraint. 1894-- 4. N_Range - when the lower or upper bound uses the discriminant of 1895-- the enclosing type. 1896-- 5. N_Range_Constraint - when the range expression uses the 1897-- discriminant of the enclosing type. 1898 1899-- Has_Pragma_Controlled (Flag27) [implementation base type only] 1900-- Defined in access type entities. It is set if a pragma Controlled 1901-- applies to the access type. 1902 1903-- Has_Pragma_Elaborate_Body (Flag150) 1904-- Defined in all entities. Set in compilation unit entities if a 1905-- pragma Elaborate_Body applies to the compilation unit. 1906 1907-- Has_Pragma_Inline (Flag157) 1908-- Defined in all entities. Set for functions and procedures for which a 1909-- pragma Inline or Inline_Always applies to the subprogram. Note that 1910-- this flag can be set even if Is_Inlined is not set. This happens for 1911-- pragma Inline (if Inline_Active is False). In other words, the flag 1912-- Has_Pragma_Inline represents the formal semantic status, and is used 1913-- for checking semantic correctness. The flag Is_Inlined indicates 1914-- whether inlining is actually active for the entity. 1915 1916-- Has_Pragma_Inline_Always (Flag230) 1917-- Defined in all entities. Set for functions and procedures for which a 1918-- pragma Inline_Always applies. Note that if this flag is set, the flag 1919-- Has_Pragma_Inline is also set. 1920 1921-- Has_Pragma_No_Inline (Flag201) 1922-- Defined in all entities. Set for functions and procedures for which a 1923-- pragma No_Inline applies. Note that if this flag is set, the flag 1924-- Has_Pragma_Inline_Always cannot be set. 1925 1926-- Has_Pragma_Ordered (Flag198) [implementation base type only] 1927-- Defined in entities for enumeration types. If set indicates that a 1928-- valid pragma Ordered was given for the type. This flag is inherited 1929-- by derived enumeration types. We don't need to distinguish the derived 1930-- case since we allow multiple occurrences of this pragma anyway. 1931 1932-- Has_Pragma_Pack (Flag121) [implementation base type only] 1933-- Defined in array and record type entities. If set, indicates that a 1934-- valid pragma Pack was given for the type. Note that this flag is not 1935-- inherited by derived type. See also the Is_Packed flag. 1936 1937-- Has_Pragma_Preelab_Init (Flag221) 1938-- Defined in type and subtype entities. If set indicates that a valid 1939-- pragma Preelaborable_Initialization applies to the type. 1940 1941-- Has_Pragma_Pure (Flag203) 1942-- Defined in all entities. If set, indicates that a valid pragma Pure 1943-- was given for the entity. In some cases, we need to test whether 1944-- Is_Pure was explicitly set using this pragma. 1945 1946-- Has_Pragma_Pure_Function (Flag179) 1947-- Defined in all entities. If set, indicates that a valid pragma 1948-- Pure_Function was given for the entity. In some cases, we need to test 1949-- whether Is_Pure was explicitly set using this pragma. We also set 1950-- this flag for some internal entities that we know should be treated 1951-- as pure for optimization purposes. 1952 1953-- Has_Pragma_Thread_Local_Storage (Flag169) 1954-- Defined in all entities. If set, indicates that a valid pragma 1955-- Thread_Local_Storage was given for the entity. 1956 1957-- Has_Pragma_Unmodified (Flag233) 1958-- Defined in all entities. Can only be set for variables (E_Variable, 1959-- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified 1960-- applies to the variable, indicating that no warning should be given 1961-- if the entity is never modified. Note that clients should generally 1962-- not test this flag directly, but instead use function Has_Unmodified. 1963 1964-- Has_Pragma_Unreferenced (Flag180) 1965-- Defined in all entities. Set if a valid pragma Unreferenced applies 1966-- to the entity, indicating that no warning should be given if the 1967-- entity has no references, but a warning should be given if it is 1968-- in fact referenced. For private types, this flag is set in both the 1969-- private entity and full entity if the pragma applies to either. Note 1970-- that clients should generally not test this flag directly, but instead 1971-- use function Has_Unreferenced. 1972 1973-- ??? this real description was clobbered 1974 1975-- Has_Pragma_Unreferenced_Objects (Flag212) 1976-- Defined in all entities. Set if a valid pragma Unused applies to an 1977-- entity, indicating that warnings should be given if the entity is 1978-- modified or referenced. This pragma is equivalent to a pair of 1979-- Unmodified and Unreferenced pragmas. 1980 1981-- Has_Pragma_Unused (Flag294) 1982-- Defined in all entities. Set if a valid pragma Unused applies to a 1983-- variable or entity, indicating that warnings should not be given if 1984-- it is never modified or referenced. Note: This pragma is exactly 1985-- equivalent Unmodified and Unreference combined. 1986 1987-- Has_Predicates (Flag250) 1988-- Defined in type and subtype entities. Set if a pragma Predicate or 1989-- Predicate aspect applies to the type or subtype, or if it inherits a 1990-- Predicate aspect from its parent or progenitor types. 1991-- 1992-- Note: this flag is set on both partial and full view of types to which 1993-- a Predicate pragma or aspect applies, and on the underlying full view 1994-- if the full view is private. 1995 1996-- Has_Primitive_Operations (Flag120) [base type only] 1997-- Defined in all type entities. Set if at least one primitive operation 1998-- is defined for the type. 1999 2000-- Has_Private_Ancestor (Flag151) 2001-- Applies to type extensions. True if some ancestor is derived from a 2002-- private type, making some components invisible and aggregates illegal. 2003-- This flag is set at the point of derivation. The legality of the 2004-- aggregate must be rechecked because it also depends on the visibility 2005-- at the point the aggregate is resolved. See sem_aggr.adb. This is part 2006-- of AI05-0115. 2007 2008-- Has_Private_Declaration (Flag155) 2009-- Defined in all entities. Set if it is the defining entity of a private 2010-- type declaration or its corresponding full declaration. This flag is 2011-- thus preserved when the full and the partial views are exchanged, to 2012-- indicate if a full type declaration is a completion. Used for semantic 2013-- checks in E.4(18) and elsewhere. 2014 2015-- Has_Private_Extension (Flag300) 2016-- Defined in tagged types. Set to indicate that the tagged type has some 2017-- private extension. Used to report a warning on public primitives added 2018-- after defining its private extensions. 2019 2020-- Has_Protected (Flag271) [base type only] 2021-- Defined in all type entities. Set on protected types themselves, and 2022-- also (recursively) on any composite type which has a component for 2023-- which Has_Protected is set, unless the protected type is declared in 2024-- the private part of an internal unit. The meaning is that restrictions 2025-- for protected types apply to this type. Note: the flag is not set on 2026-- access types, even if they designate an object that Has_Protected. 2027 2028-- Has_Qualified_Name (Flag161) 2029-- Defined in all entities. Set if the name in the Chars field has 2030-- been replaced by its qualified name, as used for debug output. See 2031-- Exp_Dbug for a full description of qualification requirements. For 2032-- some entities, the name is the fully qualified name, but there are 2033-- exceptions. In particular, for local variables in procedures, we 2034-- do not include the procedure itself or higher scopes. See also the 2035-- flag Has_Fully_Qualified_Name, which is set if the name does indeed 2036-- include the fully qualified name. 2037 2038-- Has_RACW (Flag214) 2039-- Defined in package spec entities. Set if the spec contains the 2040-- declaration of a remote access-to-classwide type. 2041 2042-- Has_Record_Rep_Clause (Flag65) [implementation base type only] 2043-- Defined in record types. Set if a record representation clause has 2044-- been given for this record type. Used to prevent more than one such 2045-- clause for a given record type. Note that this is initially cleared 2046-- for a derived type, even though the representation is inherited. See 2047-- also the flag Has_Specified_Layout. 2048 2049-- Has_Recursive_Call (Flag143) 2050-- Defined in procedures. Set if a direct parameterless recursive call 2051-- is detected while analyzing the body. Used to activate some error 2052-- checks for infinite recursion. 2053 2054-- Has_Shift_Operator (Flag267) [base type only] 2055-- Defined in integer types. Set in the base type of an integer type for 2056-- which at least one of the shift operators is defined. 2057 2058-- Has_Size_Clause (Flag29) 2059-- Defined in entities for types and objects. Set if a size clause is 2060-- defined for the entity. Used to prevent multiple Size clauses for a 2061-- given entity. Note that it is always initially cleared for a derived 2062-- type, even though the Size for such a type is inherited from a Size 2063-- clause given for the parent type. 2064 2065-- Has_Small_Clause (Flag67) 2066-- Defined in ordinary fixed point types (but not subtypes). Indicates 2067-- that a small clause has been given for the entity. Used to prevent 2068-- multiple Small clauses for a given entity. Note that it is always 2069-- initially cleared for a derived type, even though the Small for such 2070-- a type is inherited from a Small clause given for the parent type. 2071 2072-- Has_Specified_Layout (Flag100) [implementation base type only] 2073-- Defined in all type entities. Set for a record type or subtype if 2074-- the record layout has been specified by a record representation 2075-- clause. Note that this differs from the flag Has_Record_Rep_Clause 2076-- in that it is inherited by a derived type. Has_Record_Rep_Clause is 2077-- used to indicate that the type is mentioned explicitly in a record 2078-- representation clause, and thus is not inherited by a derived type. 2079-- This flag is always False for non-record types. 2080 2081-- Has_Specified_Stream_Input (Flag190) 2082-- Has_Specified_Stream_Output (Flag191) 2083-- Has_Specified_Stream_Read (Flag192) 2084-- Has_Specified_Stream_Write (Flag193) 2085-- Defined in all type and subtype entities. Set for a given view if the 2086-- corresponding stream-oriented attribute has been defined by an 2087-- attribute definition clause. When such a clause occurs, a TSS is set 2088-- on the underlying full view; the flags are used to track visibility of 2089-- the attribute definition clause for partial or incomplete views. 2090 2091-- Has_Static_Discriminants (Flag211) 2092-- Defined in record subtypes constrained by discriminant values. Set if 2093-- all the discriminant values have static values, meaning that in the 2094-- case of a variant record, the component list can be trimmed down to 2095-- include only the components corresponding to these discriminants. 2096 2097-- Has_Static_Predicate (Flag269) 2098-- Defined in all types and subtypes. Set if the type (which must be a 2099-- scalar type) has a predicate whose expression is predicate-static. 2100-- This can result from the use of any Predicate, Static_Predicate, or 2101-- Dynamic_Predicate aspect. We can distinguish these cases by testing 2102-- Has_Static_Predicate_Aspect and Has_Dynamic_Predicate_Aspect. See 2103-- description of the latter flag for further information on dynamic 2104-- predicates which are also static. 2105 2106-- Has_Static_Predicate_Aspect (Flag259) 2107-- Defined in all types and subtypes. Set if a Static_Predicate aspect 2108-- applies to the type. Note that we can tell if a static predicate is 2109-- present by looking at Has_Static_Predicate, but this could have come 2110-- from a Predicate aspect or pragma or even from a Dynamic_Predicate 2111-- aspect. When we need to know the difference (e.g. to know what set of 2112-- check policies apply, use this flag and Has_Dynamic_Predicate_Aspect 2113-- to determine which case we have). 2114 2115-- Has_Storage_Size_Clause (Flag23) [implementation base type only] 2116-- Defined in task types and access types. It is set if a Storage_Size 2117-- clause is present for the type. Used to prevent multiple clauses for 2118-- one type. Note that this flag is initially cleared for a derived type 2119-- even though the Storage_Size for such a type is inherited from a 2120-- Storage_Size clause given for the parent type. Note that in the case 2121-- of access types, this flag is defined only in the root type, since a 2122-- storage size clause cannot be given to a derived type. 2123 2124-- Has_Stream_Size_Clause (Flag184) 2125-- Defined in all entities. It is set for types which have a Stream_Size 2126-- clause attribute. Used to prevent multiple Stream_Size clauses for a 2127-- given entity, and also whether it is necessary to check for a stream 2128-- size clause. 2129 2130-- Has_Task (Flag30) [base type only] 2131-- Defined in all type entities. Set on task types themselves, and also 2132-- (recursively) on any composite type which has a component for which 2133-- Has_Task is set. The meaning is that an allocator or declaration of 2134-- such an object must create the required tasks. Note: the flag is not 2135-- set on access types, even if they designate an object that Has_Task. 2136 2137-- Has_Timing_Event (Flag289) [base type only] 2138-- Defined in all type entities. Set on language defined type 2139-- Ada.Real_Time.Timing_Events.Timing_Event, and also (recursively) on 2140-- any composite type which has a component for which Has_Timing_Event 2141-- is set. Used for the No_Local_Timing_Event restriction. 2142 2143-- Has_Thunks (Flag228) 2144-- Applies to E_Constant entities marked Is_Tag. True for secondary tag 2145-- referencing a dispatch table whose contents are pointers to thunks. 2146 2147-- Has_Unchecked_Union (Flag123) [base type only] 2148-- Defined in all type entities. Set on unchecked unions themselves 2149-- and (recursively) on any composite type which has a component for 2150-- which Has_Unchecked_Union is set. The meaning is that a comparison 2151-- operation or 'Valid_Scalars reference for the type is not permitted. 2152-- Note that the flag is not set on access types, even if they designate 2153-- an object that has the flag Has_Unchecked_Union set. 2154 2155-- Has_Unknown_Discriminants (Flag72) 2156-- Defined in all entities. Set for types with unknown discriminants. 2157-- Types can have unknown discriminants either from their declaration or 2158-- through type derivation. The use of this flag exactly meets the spec 2159-- in RM 3.7(26). Note that all class-wide types are considered to have 2160-- unknown discriminants. Note that both flags Has_Discriminants and 2161-- Has_Unknown_Discriminants may be true for a type. Class-wide types and 2162-- their subtypes have unknown discriminants and can have declared ones 2163-- as well. Private types declared with unknown discriminants may have a 2164-- full view that has explicit discriminants, and both flag will be set 2165-- on the partial view, to ensure that discriminants are properly 2166-- inherited in certain contexts. 2167 2168-- Has_Visible_Refinement (Flag263) 2169-- Defined in E_Abstract_State entities. Set when a state has at least 2170-- one refinement constituent and analysis is in the region between 2171-- pragma Refined_State and the end of the package body declarations. 2172 2173-- Has_Volatile_Components (Flag87) [implementation base type only] 2174-- Defined in all types and objects. Set only for an array type or array 2175-- object if a valid pragma Volatile_Components or a valid pragma 2176-- Atomic_Components applies to the type or object. Note that in the case 2177-- of an object, this flag is only set on the object if there was an 2178-- explicit pragma for the object. In other words, the proper test for 2179-- whether an object has volatile components is to see if either the 2180-- object or its base type has this flag set. Note that in the case of a 2181-- type the pragma will be chained to the rep item chain of the first 2182-- subtype in the usual manner. 2183 2184-- Has_Xref_Entry (Flag182) 2185-- Defined in all entities. Set if an entity has an entry in the Xref 2186-- information generated in ali files. This is true for all source 2187-- entities in the extended main source file. It is also true of entities 2188-- in other packages that are referenced directly or indirectly from the 2189-- main source file (indirect reference occurs when the main source file 2190-- references an entity with a type reference. See package Lib.Xref for 2191-- further details). 2192 2193-- Has_Yield_Aspect (Flag308) 2194-- Defined in subprograms, generic subprograms, entries, entry families. 2195-- Set if the entity has aspect Yield. 2196 2197-- Hiding_Loop_Variable (Node8) 2198-- Defined in variables. Set only if a variable of a discrete type is 2199-- hidden by a loop variable in the same local scope, in which case 2200-- the Hiding_Loop_Variable field of the hidden variable points to 2201-- the E_Loop_Parameter entity doing the hiding. Used in processing 2202-- warning messages if the hidden variable turns out to be unused 2203-- or is referenced without being set. 2204 2205-- Hidden_In_Formal_Instance (Elist30) 2206-- Defined on actuals for formal packages. Entities on the list are 2207-- formals that are hidden outside of the formal package when this 2208-- package is not declared with a box, or the formal itself is not 2209-- defaulted (see RM 12.7 (10)). Their visibility is restored on exit 2210-- from the current generic, because the actual for the formal package 2211-- may be used subsequently in the current unit. 2212 2213-- Homonym (Node4) 2214-- Defined in all entities. Link for list of entities that have the 2215-- same source name and that are declared in the same or enclosing 2216-- scopes. Homonyms in the same scope are overloaded. Used for name 2217-- resolution and for the generation of debugging information. 2218 2219-- Ignore_SPARK_Mode_Pragmas (Flag301) 2220-- Present in concurrent type, entry, operator, [generic] package, 2221-- package body, [generic] subprogram, and subprogram body entities. 2222-- Set when the entity appears in an instance subject to SPARK_Mode 2223-- "off" and indicates that all SPARK_Mode pragmas found within must 2224-- be ignored. 2225 2226-- Implementation_Base_Type (synthesized) 2227-- Applies to all entities. For types, similar to Base_Type, but never 2228-- returns a private type when applied to a non-private type. Instead in 2229-- this case, it always returns the Underlying_Type of the base type, so 2230-- that we still have a concrete type. For entities other than types, 2231-- returns the entity unchanged. 2232 2233-- Import_Pragma (Node35) 2234-- Defined in subprogram entities. Set if a valid pragma Import or pragma 2235-- Import_Function or pragma Import_Procedure applies to the subprogram, 2236-- in which case this field points to the pragma (we can't use the normal 2237-- Rep_Item chain mechanism, because a single pragma Import can apply 2238-- to multiple subprogram entities). 2239 2240-- In_Package_Body (Flag48) 2241-- Defined in package entities. Set on the entity that denotes the 2242-- package (the defining occurrence of the package declaration) while 2243-- analyzing and expanding the package body. Reset on completion of 2244-- analysis/expansion. 2245 2246-- In_Private_Part (Flag45) 2247-- Defined in all entities. Can be set only in package entities and 2248-- objects. For package entities, this flag is set to indicate that the 2249-- private part of the package is being analyzed. The flag is reset at 2250-- the end of the package declaration. For objects it indicates that the 2251-- declaration of the object occurs in the private part of a package. 2252 2253-- Incomplete_Actuals (Elist24) 2254-- Defined on package entities that are instances. Indicates the actuals 2255-- types in the instantiation that are limited views. If this list is 2256-- not empty, the instantiation, which appears in a package declaration, 2257-- is relocated to the corresponding package body, which must have a 2258-- corresponding nonlimited with_clause. 2259 2260-- Initialization_Statements (Node28) 2261-- Defined in constants and variables. For a composite object initialized 2262-- initialized with an aggregate that has been converted to a sequence 2263-- of assignments, points to a block statement containing the 2264-- assignments. 2265 2266-- Inner_Instances (Elist23) 2267-- Defined in generic units. Contains element list of units that are 2268-- instantiated within the given generic. Used to diagnose circular 2269-- instantiations. 2270 2271-- Interface_Alias (Node25) 2272-- Defined in subprograms that cover a primitive operation of an abstract 2273-- interface type. Can be set only if the Is_Hidden flag is also set, 2274-- since such entities are always hidden. Points to its associated 2275-- interface subprogram. It is used to register the subprogram in 2276-- secondary dispatch table of the interface (Ada 2005: AI-251). 2277 2278-- Interface_Name (Node21) 2279-- Defined in constants, variables, exceptions, functions, procedures, 2280-- and packages. Set to Empty unless an export, import, or interface name 2281-- pragma has explicitly specified an external name, in which case it 2282-- references an N_String_Literal node for the specified external name. 2283-- Note that if this field is Empty, and Is_Imported or Is_Exported is 2284-- set, then the default interface name is the name of the entity, cased 2285-- in a manner that is appropriate to the system in use. Note that 2286-- Interface_Name is ignored if an address clause is present (since it 2287-- is meaningless in this case). 2288 2289-- Interfaces (Elist25) 2290-- Defined in record types and subtypes. List of abstract interfaces 2291-- implemented by a tagged type that are not already implemented by the 2292-- ancestors (Ada 2005: AI-251). 2293 2294-- Invariant_Procedure (synthesized) 2295-- Defined in types and subtypes. Set for private types and their full 2296-- views if one or more [class-wide] invariants apply to the type, or 2297-- when the type inherits class-wide invariants from a parent type or 2298-- an interface, or when the type is an array and its component type is 2299-- subject to an invariant, or when the type is record and contains a 2300-- component subject to an invariant (property is recursive). Points to 2301-- to the entity for a procedure which checks all these invariants. The 2302-- invariant procedure takes a single argument of the given type, and 2303-- returns if the invariant holds, or raises exception Assertion_Error 2304-- with an appropriate message if it does not hold. This attribute is 2305-- defined but always Empty for private subtypes. 2306 2307-- Note: the reason this is marked as a synthesized attribute is that the 2308-- way this is stored is as an element of the Subprograms_For_Type field. 2309 2310-- In_Use (Flag8) 2311-- Defined in packages and types. Set when analyzing a use clause for 2312-- the corresponding entity. Reset at end of corresponding declarative 2313-- part. The flag on a type is also used to determine the visibility of 2314-- the primitive operators of the type. 2315 2316-- Is_Abstract_Subprogram (Flag19) 2317-- Defined in all subprograms and entries. Set for abstract subprograms. 2318-- Always False for enumeration literals and entries. See also 2319-- Requires_Overriding. 2320 2321-- Is_Abstract_Type (Flag146) 2322-- Defined in all types. Set for abstract types. 2323 2324-- Is_Access_Constant (Flag69) 2325-- Defined in access types and subtypes. Indicates that the keyword 2326-- constant was present in the access type definition. 2327 2328-- Is_Access_Protected_Subprogram_Type (synthesized) 2329-- Applies to all types, true for named and anonymous access to 2330-- protected subprograms. 2331 2332-- Is_Access_Type (synthesized) 2333-- Applies to all entities, true for access types and subtypes 2334 2335-- Is_Access_Object_Type (synthesized) 2336-- Applies to all entities, true for access-to-object types and subtypes 2337 2338-- Is_Activation_Record (Flag305) 2339-- Applies to E_In_Parameters generated in Exp_Unst for nested 2340-- subprograms, to mark the added formal that carries the activation 2341-- record created in the enclosing subprogram. 2342 2343-- Is_Actual_Subtype (Flag293) 2344-- Defined on all types, true for the generated constrained subtypes 2345-- that are built for unconstrained composite actuals. 2346 2347-- Is_Ada_2005_Only (Flag185) 2348-- Defined in all entities, true if a valid pragma Ada_05 or Ada_2005 2349-- applies to the entity which specifically names the entity, indicating 2350-- that the entity is Ada 2005 only. Note that this flag is not set if 2351-- the entity is part of a unit compiled with the normal no-argument form 2352-- of pragma Ada_05 or Ada_2005. 2353 2354-- Is_Ada_2012_Only (Flag199) 2355-- Defined in all entities, true if a valid pragma Ada_12 or Ada_2012 2356-- applies to the entity which specifically names the entity, indicating 2357-- that the entity is Ada 2012 only. Note that this flag is not set if 2358-- the entity is part of a unit compiled with the normal no-argument form 2359-- of pragma Ada_12 or Ada_2012. 2360 2361-- Is_Aliased (Flag15) 2362-- Defined in all entities. Set for objects and types whose declarations 2363-- carry the keyword aliased, and on record components that have the 2364-- keyword. For Ada 2012, also applies to formal parameters. 2365 2366-- Is_Array_Type (synthesized) 2367-- Applies to all entities, true for array types and subtypes 2368 2369-- Is_Asynchronous (Flag81) 2370-- Defined in all type entities and in procedure entities. Set 2371-- if a pragma Asynchronous applies to the entity. 2372 2373-- Is_Atomic (Flag85) 2374-- Defined in all type entities, and also in constants, components, and 2375-- variables. Set if a pragma Atomic or Shared applies to the entity. 2376-- In the case of private and incomplete types, this flag is set in 2377-- both the partial view and the full view. 2378 2379-- Is_Full_Access (synth) 2380-- Defined in all type entities, and also in constants, components and 2381-- variables. Set if an aspect/pragma Atomic/Shared, or an aspect/pragma 2382-- Volatile_Full_Access or an Ada 2020 aspect Full_Access_Only applies 2383-- to the entity. In the case of private and incomplete types, the flag 2384-- applies to both the partial view and the full view. 2385 2386-- Is_Base_Type (synthesized) 2387-- Applies to type and subtype entities. True if entity is a base type. 2388 2389-- Is_Bit_Packed_Array (Flag122) [implementation base type only] 2390-- Defined in all entities. This flag is set for a packed array type that 2391-- is bit-packed (i.e. the component size is known by the front end and 2392-- is in the range 1-63 but not a multiple of 8). Is_Packed is always set 2393-- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be 2394-- set without Is_Bit_Packed_Array if the component size is not known by 2395-- the front-end or for the case of an array having one or more index 2396-- types that are enumeration types with non-standard representation. 2397 2398-- Is_Boolean_Type (synthesized) 2399-- Applies to all entities, true for boolean types and subtypes, 2400-- i.e. Standard.Boolean and all types ultimately derived from it. 2401 2402-- Is_Called (Flag102) 2403-- Defined in subprograms and packages. Set if a subprogram is called 2404-- from the unit being compiled or a unit in the closure. Also set for 2405-- a package that contains called subprograms. Used only for inlining. 2406 2407-- Is_Character_Type (Flag63) 2408-- Defined in all entities. Set for character types and subtypes, 2409-- i.e. enumeration types that have at least one character literal. 2410 2411-- Is_Checked_Ghost_Entity (Flag277) 2412-- Applies to all entities. Set for abstract states, [generic] packages, 2413-- [generic] subprograms, components, discriminants, formal parameters, 2414-- objects, package bodies, subprogram bodies, and [sub]types subject to 2415-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2416-- subject to Assertion_Policy Ghost => Check. 2417 2418-- Is_Child_Unit (Flag73) 2419-- Defined in all entities. Set only for defining entities of program 2420-- units that are child units (but False for subunits). 2421 2422-- Is_Class_Wide_Clone (Flag290) 2423-- Defined on subprogram entities. Set for subprograms built in order 2424-- to implement properly the inheritance of class-wide pre- or post- 2425-- conditions when the condition contains calls to other primitives 2426-- of the ancestor type. Used to implement AI12-0195. 2427 2428-- Is_Class_Wide_Equivalent_Type (Flag35) 2429-- Defined in record types and subtypes. Set to True, if the type acts 2430-- as a class-wide equivalent type, i.e. the Equivalent_Type field of 2431-- some class-wide subtype entity references this record type. 2432 2433-- Is_Class_Wide_Type (synthesized) 2434-- Applies to all entities, true for class wide types and subtypes 2435 2436-- Is_Compilation_Unit (Flag149) 2437-- Defined in all entities. Set if the entity is a package or subprogram 2438-- entity for a compilation unit other than a subunit (since we treat 2439-- subunits as part of the same compilation operation as the ultimate 2440-- parent, we do not consider them to be separate units for this flag). 2441 2442-- Is_Completely_Hidden (Flag103) 2443-- Defined on discriminants. Only set on girder discriminants of 2444-- untagged types. When set, the entity is a girder discriminant of a 2445-- derived untagged type which is not directly visible in the derived 2446-- type because the derived type or one of its ancestors have renamed the 2447-- discriminants in the root type. Note: there are girder discriminants 2448-- which are not Completely_Hidden (e.g. discriminants of a root type). 2449 2450-- Is_Composite_Type (synthesized) 2451-- Applies to all entities, true for all composite types and subtypes. 2452-- Either Is_Composite_Type or Is_Elementary_Type (but not both) is true 2453-- of any type. 2454 2455-- Is_Concurrent_Record_Type (Flag20) 2456-- Defined in record types and subtypes. Set if the type was created 2457-- by the expander to represent a task or protected type. For every 2458-- concurrent type, such as record type is constructed, and task and 2459-- protected objects are instances of this record type at run time 2460-- (The backend will replace declarations of the concurrent type using 2461-- the declarations of the corresponding record type). See Exp_Ch9 for 2462-- further details. 2463 2464-- Is_Concurrent_Type (synthesized) 2465-- Applies to all entities, true for task types and subtypes and for 2466-- protected types and subtypes. 2467 2468-- Is_Constant_Object (synthesized) 2469-- Applies to all entities, true for E_Constant, E_Loop_Parameter, and 2470-- E_In_Parameter entities. 2471 2472-- Is_Constrained (Flag12) 2473-- Defined in types or subtypes which may have index, discriminant 2474-- or range constraint (i.e. array types and subtypes, record types 2475-- and subtypes, string types and subtypes, and all numeric types). 2476-- Set if the type or subtype is constrained. 2477 2478-- Is_Constr_Subt_For_U_Nominal (Flag80) 2479-- Defined in all types and subtypes. Set only for the constructed 2480-- subtype of an object whose nominal subtype is unconstrained. Note 2481-- that the constructed subtype itself will be constrained. 2482 2483-- Is_Constr_Subt_For_UN_Aliased (Flag141) 2484-- Defined in all types and subtypes. This flag can be set only if 2485-- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in 2486-- addition the object concerned is aliased. This flag is used by 2487-- the backend to determine whether a template must be constructed. 2488 2489-- Is_Constructor (Flag76) 2490-- Defined in function and procedure entities. Set if a pragma 2491-- CPP_Constructor applies to the subprogram. 2492 2493-- Is_Controlled_Active (Flag42) [base type only] 2494-- Defined in all type entities. Indicates that the type is controlled, 2495-- i.e. is either a descendant of Ada.Finalization.Controlled or of 2496-- Ada.Finalization.Limited_Controlled. 2497 2498-- Is_Controlled (synth) [base type only] 2499-- Defined in all type entities. Set if Is_Controlled_Active is set for 2500-- the type, and Disable_Controlled is not set. 2501 2502-- Is_Controlling_Formal (Flag97) 2503-- Defined in all Formal_Kind entities. Marks the controlling parameters 2504-- of dispatching operations. 2505 2506-- Is_CPP_Class (Flag74) 2507-- Defined in all type entities, set only for tagged types to which a 2508-- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied. 2509 2510-- Is_CUDA_Kernel (Flag118) 2511-- Defined in function and procedure entities. Set if the subprogram is a 2512-- CUDA kernel. 2513 2514-- Is_Decimal_Fixed_Point_Type (synthesized) 2515-- Applies to all type entities, true for decimal fixed point 2516-- types and subtypes. 2517 2518-- Is_Descendant_Of_Address (Flag223) 2519-- Defined in all entities. True if the entity is type System.Address, 2520-- or (recursively) a subtype or derived type of System.Address. 2521 2522-- Is_DIC_Procedure (Flag132) 2523-- Defined in functions and procedures. Set for a generated procedure 2524-- which verifies the assumption of pragma Default_Initial_Condition at 2525-- run time. 2526 2527-- Is_Discrete_Or_Fixed_Point_Type (synthesized) 2528-- Applies to all entities, true for all discrete types and subtypes 2529-- and all fixed-point types and subtypes. 2530 2531-- Is_Discrete_Type (synthesized) 2532-- Applies to all entities, true for all discrete types and subtypes 2533 2534-- Is_Discrim_SO_Function (Flag176) 2535-- Defined in all entities. Set only in E_Function entities that Layout 2536-- creates to compute discriminant-dependent dynamic size/offset values. 2537 2538-- Is_Discriminant_Check_Function (Flag264) 2539-- Defined in all entities. Set only in E_Function entities for functions 2540-- created to do discriminant checks. 2541 2542-- Is_Discriminal (synthesized) 2543-- Applies to all entities, true for renamings of discriminants. Such 2544-- entities appear as constants or IN parameters. 2545 2546-- Is_Dispatch_Table_Entity (Flag234) 2547-- Applies to all entities. Set to indicate to the backend that this 2548-- entity is associated with a dispatch table. 2549 2550-- Is_Dispatching_Operation (Flag6) 2551-- Defined in all entities. Set for procedures, functions, generic 2552-- procedures, and generic functions if the corresponding operation 2553-- is dispatching. 2554 2555-- Is_Dynamic_Scope (synthesized) 2556-- Applies to all Entities. Returns True if the entity is a dynamic 2557-- scope (i.e. a block, subprogram, task_type, entry or extended return 2558-- statement). 2559 2560-- Is_Elaboration_Checks_OK_Id (Flag148) 2561-- Defined in elaboration targets (see terminology in Sem_Elab). Set when 2562-- the target appears in a region which is subject to elabled elaboration 2563-- checks. Such targets are allowed to generate run-time conditional ABE 2564-- checks or guaranteed ABE failures. 2565 2566-- Is_Elaboration_Target (synthesized) 2567-- Applies to all entities, True only for elaboration targets (see the 2568-- terminology in Sem_Elab). 2569 2570-- Is_Elaboration_Warnings_OK_Id (Flag304) 2571-- Defined in elaboration targets (see terminology in Sem_Elab). Set when 2572-- the target appears in a region with elaboration warnings enabled. 2573 2574-- Is_Elementary_Type (synthesized) 2575-- Applies to all entities, True for all elementary types and subtypes. 2576-- Either Is_Composite_Type or Is_Elementary_Type (but not both) is true 2577-- of any type. 2578 2579-- Is_Eliminated (Flag124) 2580-- Defined in type entities, subprogram entities, and object entities. 2581-- Indicates that the corresponding entity has been eliminated by use 2582-- of pragma Eliminate. Also used to mark subprogram entities whose 2583-- declaration and body are within unreachable code that is removed. 2584 2585-- Is_Entry (synthesized) 2586-- Applies to all entities, True only for entry and entry family 2587-- entities and False for all other entity kinds. 2588 2589-- Is_Entry_Formal (Flag52) 2590-- Defined in all entities. Set only for entry formals (which can only 2591-- be in, in-out or out parameters). This flag is used to speed up the 2592-- test for the need to replace references in Exp_Ch2. 2593 2594-- Is_Entry_Wrapper (Flag297) 2595-- Defined on wrappers created for entries that have precondition aspects 2596 2597-- Is_Enumeration_Type (synthesized) 2598-- Defined in all entities, true for enumeration types and subtypes 2599 2600-- Is_Exception_Handler (Flag286) 2601-- Defined in blocks. Set if the block serves only as a scope of an 2602-- exception handler with a choice parameter. Such a block does not 2603-- physically appear in the tree. 2604 2605-- Is_Exported (Flag99) 2606-- Defined in all entities. Set if the entity is exported. For now we 2607-- only allow the export of constants, exceptions, functions, procedures 2608-- and variables, but that may well change later on. Exceptions can only 2609-- be exported in the Java VM implementation of GNAT, which is retired. 2610 2611-- Is_External_State (synthesized) 2612-- Applies to all entities, true for abstract states that are subject to 2613-- option External or Synchronous. 2614 2615-- Is_Finalized_Transient (Flag252) 2616-- Defined in constants, loop parameters of generalized iterators, and 2617-- variables. Set when a transient object has been finalized by one of 2618-- the transient finalization mechanisms. The flag prevents the double 2619-- finalization of the object. 2620 2621-- Is_Finalizer (synthesized) 2622-- Applies to all entities, true for procedures containing finalization 2623-- code to process local or library level objects. 2624 2625-- Is_First_Subtype (Flag70) 2626-- Defined in all entities. True for first subtypes (RM 3.2.1(6)), 2627-- i.e. the entity in the type declaration that introduced the type. 2628-- This may be the base type itself (e.g. for record declarations and 2629-- enumeration type declarations), or it may be the first subtype of 2630-- an anonymous base type (e.g. for integer type declarations or 2631-- constrained array declarations). 2632 2633-- Is_Fixed_Point_Type (synthesized) 2634-- Applies to all entities, true for decimal and ordinary fixed 2635-- point types and subtypes. 2636 2637-- Is_Floating_Point_Type (synthesized) 2638-- Applies to all entities, true for float types and subtypes 2639 2640-- Is_Formal (synthesized) 2641-- Applies to all entities, true for IN, IN OUT and OUT parameters 2642 2643-- Is_Formal_Object (synthesized) 2644-- Applies to all entities, true for generic IN and IN OUT parameters 2645 2646-- Is_Formal_Subprogram (Flag111) 2647-- Defined in all entities. Set for generic formal subprograms. 2648 2649-- Is_Frozen (Flag4) 2650-- Defined in all type and subtype entities. Set if type or subtype has 2651-- been frozen. 2652 2653-- Is_Generic_Actual_Subprogram (Flag274) 2654-- Defined on functions and procedures. Set on the entity of the renaming 2655-- declaration created within an instance for an actual subprogram. 2656-- Used to generate constraint checks on calls to these subprograms, even 2657-- within an instance of a predefined run-time unit, in which checks 2658-- are otherwise suppressed. 2659 2660-- Is_Generic_Actual_Type (Flag94) 2661-- Defined in all type and subtype entities. Set in the subtype 2662-- declaration that renames the generic formal as a subtype of the 2663-- actual. Guarantees that the subtype is not static within the instance. 2664-- Also used during analysis of an instance, to simplify resolution of 2665-- accidental overloading that occurs when different formal types get the 2666-- same actual. 2667 2668-- Is_Generic_Instance (Flag130) 2669-- Defined in all entities. Set to indicate that the entity is an 2670-- instance of a generic unit, or a formal package (which is an instance 2671-- of the template). 2672 2673-- Is_Generic_Subprogram (synthesized) 2674-- Applies to all entities. Yields True for a generic subprogram 2675-- (generic function, generic subprogram), False for all other entities. 2676 2677-- Is_Generic_Type (Flag13) 2678-- Defined in all entities. Set for types which are generic formal types. 2679-- Such types have an Ekind that corresponds to their classification, so 2680-- the Ekind cannot be used to identify generic formal types. 2681 2682-- Is_Generic_Unit (synthesized) 2683-- Applies to all entities. Yields True for a generic unit (generic 2684-- package, generic function, generic procedure), and False for all 2685-- other entities. 2686 2687-- Is_Ghost_Entity (synthesized) 2688-- Applies to all entities. Yields True for abstract states, [generic] 2689-- packages, [generic] subprograms, components, discriminants, formal 2690-- parameters, objects, package bodies, subprogram bodies, and [sub]types 2691-- subject to pragma Ghost or those that inherit the Ghost property from 2692-- an enclosing construct. 2693 2694-- Is_Hidden (Flag57) 2695-- Defined in all entities. Set for all entities declared in the 2696-- private part or body of a package. Also marks generic formals of a 2697-- formal package declared without a box. For library level entities, 2698-- this flag is set if the entity is not publicly visible. This flag 2699-- is reset when compiling the body of the package where the entity 2700-- is declared, when compiling the private part or body of a public 2701-- child unit, and when compiling a private child unit (see Install_ 2702-- Private_Declaration in sem_ch7). 2703 2704-- Is_Hidden_Non_Overridden_Subpgm (Flag2) 2705-- Defined in all entities. Set for implicitly declared subprograms 2706-- that require overriding or are null procedures, and are hidden by 2707-- a non-fully conformant homograph with the same characteristics 2708-- (Ada RM 8.3 12.3/2). 2709 2710-- Is_Hidden_Open_Scope (Flag171) 2711-- Defined in all entities. Set for a scope that contains the 2712-- instantiation of a child unit, and whose entities are not visible 2713-- during analysis of the instance. 2714 2715-- Is_Ignored_Ghost_Entity (Flag278) 2716-- Applies to all entities. Set for abstract states, [generic] packages, 2717-- [generic] subprograms, components, discriminants, formal parameters, 2718-- objects, package bodies, subprogram bodies, and [sub]types subject to 2719-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2720-- subject to Assertion_Policy Ghost => Ignore. 2721 2722-- Is_Ignored_Transient (Flag295) 2723-- Defined in constants, loop parameters of generalized iterators, and 2724-- variables. Set when a transient object must be processed by one of 2725-- the transient finalization mechanisms. Once marked, a transient is 2726-- intentionally ignored by the general finalization mechanism because 2727-- its clean up actions are context specific. 2728 2729-- Is_Immediately_Visible (Flag7) 2730-- Defined in all entities. Set if entity is immediately visible, i.e. 2731-- is defined in some currently open scope (RM 8.3(4)). 2732 2733-- Is_Implementation_Defined (Flag254) 2734-- Defined in all entities. Set if a pragma Implementation_Defined is 2735-- applied to the pragma. Used to mark all implementation defined 2736-- identifiers in standard library packages, and to implement the 2737-- restriction No_Implementation_Identifiers. 2738 2739-- Is_Imported (Flag24) 2740-- Defined in all entities. Set if the entity is imported. For now we 2741-- only allow the import of exceptions, functions, procedures, packages, 2742-- constants, and variables. Exceptions, packages, and types can only be 2743-- imported in the Java VM implementation, which is retired. 2744 2745-- Is_Incomplete_Or_Private_Type (synthesized) 2746-- Applies to all entities, true for private and incomplete types 2747 2748-- Is_Incomplete_Type (synthesized) 2749-- Applies to all entities, true for incomplete types and subtypes 2750 2751-- Is_Independent (Flag268) 2752-- Defined in all types and objects. Set if a valid pragma or aspect 2753-- Independent applies to the entity, or for a component if a valid 2754-- pragma or aspect Independent_Components applies to the enclosing 2755-- record type. Also set if a pragma Shared or pragma Atomic applies to 2756-- the entity, or if the declaration of the entity carries the Aliased 2757-- keyword. For Ada 2012, also applies to formal parameters. In the 2758-- case of private and incomplete types, this flag is set in both the 2759-- partial view and the full view. 2760 2761-- Is_Initial_Condition_Procedure (Flag302) 2762-- Defined in functions and procedures. Set for a generated procedure 2763-- which verifies the assumption of pragma Initial_Condition at run time. 2764 2765-- Is_Inlined (Flag11) 2766-- Defined in all entities. Set for functions and procedures which are 2767-- to be inlined. For subprograms created during expansion, this flag 2768-- may be set directly by the expander to request inlining. Also set 2769-- for packages that contain inlined subprograms, whose bodies must be 2770-- be compiled. Is_Inlined is also set on generic subprograms and is 2771-- inherited by their instances. It is also set on the body entities 2772-- of inlined subprograms. See also Has_Pragma_Inline. 2773 2774-- Is_Inlined_Always (Flag1) 2775-- Defined in subprograms. Set for functions and procedures which are 2776-- always inlined in GNATprove mode. GNATprove uses this flag to know 2777-- when a body does not need to be analyzed. The value of this flag is 2778-- only meaningful if Body_To_Inline is not Empty for the subprogram. 2779 2780-- Is_Instantiated (Flag126) 2781-- Defined in generic packages and generic subprograms. Set if the unit 2782-- is instantiated from somewhere in the extended main source unit. This 2783-- flag is used to control warnings about the unit being uninstantiated. 2784-- Also set in a package that is used as an actual for a generic package 2785-- formal in an instantiation. Also set on a parent instance, in the 2786-- instantiation of a child, which is implicitly declared in the parent. 2787 2788-- Is_Integer_Type (synthesized) 2789-- Applies to all entities, true for integer types and subtypes 2790 2791-- Is_Interface (Flag186) 2792-- Defined in record types and subtypes. Set to indicate that the current 2793-- entity corresponds to an abstract interface. Because abstract 2794-- interfaces are conceptually a special kind of abstract tagged type 2795-- we represent them by means of tagged record types and subtypes 2796-- marked with this attribute. This allows us to reuse most of the 2797-- compiler support for abstract tagged types to implement interfaces 2798-- (Ada 2005: AI-251). 2799 2800-- Is_Internal (Flag17) 2801-- Defined in all entities. Set to indicate an entity created during 2802-- semantic processing (e.g. an implicit type, or a temporary). The 2803-- current uses of this flag are: 2804-- 2805-- 1) Internal entities (such as temporaries generated for the result 2806-- of an inlined function call or dummy variables generated for the 2807-- debugger). Set to indicate that they need not be initialized, even 2808-- when scalars are initialized or normalized. 2809-- 2810-- 2) Predefined primitives of tagged types. Set to mark that they 2811-- have specific properties: first they are primitives even if they 2812-- are not defined in the type scope (the freezing point is not 2813-- necessarily in the same scope), and second the predefined equality 2814-- can be overridden by a user-defined equality, no body will be 2815-- generated in this case. 2816-- 2817-- 3) Object declarations generated by the expander that are implicitly 2818-- imported or exported so that they can be marked in Sprint output. 2819-- 2820-- 4) Internal entities in the list of primitives of tagged types that 2821-- are used to handle secondary dispatch tables. These entities have 2822-- also the attribute Interface_Alias. 2823 2824-- Is_Interrupt_Handler (Flag89) 2825-- Defined in procedures. Set if a pragma Interrupt_Handler applies 2826-- to the procedure. The procedure must be parameterless, and on all 2827-- targets except AAMP it must be a protected procedure. 2828 2829-- Is_Intrinsic_Subprogram (Flag64) 2830-- Defined in functions and procedures. It is set if a valid pragma 2831-- Interface or Import is present for this subprogram specifying 2832-- convention Intrinsic. Valid means that the name and profile of the 2833-- subprogram match the requirements of one of the recognized intrinsic 2834-- subprograms (see package Sem_Intr for details). Note: the value of 2835-- Convention for such an entity will be set to Convention_Intrinsic, 2836-- but it is the setting of Is_Intrinsic_Subprogram, NOT simply having 2837-- convention set to intrinsic, which causes intrinsic code to be 2838-- generated. 2839 2840-- Is_Invariant_Procedure (Flag257) 2841-- Defined in functions and procedures. Set for a generated invariant 2842-- procedure which verifies the invariants of both the partial and full 2843-- views of a private type or private extension as well as any inherited 2844-- class-wide invariants from parent types or interfaces. 2845 2846-- Is_Itype (Flag91) 2847-- Defined in all entities. Set to indicate that a type is an Itype, 2848-- which means that the declaration for the type does not appear 2849-- explicitly in the tree. Instead the backend will elaborate the type 2850-- when it is first used. Has_Delayed_Freeze can be set for Itypes, and 2851-- the meaning is that the first use (the one which causes the type to be 2852-- defined) will be the freeze node. Note that an important restriction 2853-- on Itypes is that the first use of such a type (the one that causes it 2854-- to be defined) must be in the same scope as the type. 2855 2856-- Is_Known_Non_Null (Flag37) 2857-- Defined in all entities. Relevant (and can be set) only for 2858-- objects of an access type. It is set if the object is currently 2859-- known to have a non-null value (meaning that no access checks 2860-- are needed). The indication can for example come from assignment 2861-- of an access parameter or an allocator whose value is known non-null. 2862-- 2863-- Note: this flag is set according to the sequential flow of the 2864-- program, watching the current value of the variable. However, this 2865-- processing can miss cases of changing the value of an aliased or 2866-- constant object, so even if this flag is set, it should not be 2867-- believed if the variable is aliased or volatile. It would be a 2868-- little neater to avoid the flag being set in the first place in 2869-- such cases, but that's trickier, and there is only one place that 2870-- tests the value anyway. 2871-- 2872-- The flag is dynamically set and reset as semantic analysis and 2873-- expansion proceeds. Its value is meaningless once the tree is 2874-- fully constructed, since it simply indicates the last state. 2875-- Thus this flag has no meaning to the backend. 2876 2877-- Is_Known_Null (Flag204) 2878-- Defined in all entities. Relevant (and can be set ) only for 2879-- objects of an access type. It is set if the object is currently known 2880-- to have a null value (meaning that a dereference will surely raise 2881-- constraint error exception). The indication can come from an 2882-- assignment or object declaration. 2883-- 2884-- The comments above about sequential flow and aliased and volatile for 2885-- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag. 2886 2887-- Is_Known_Valid (Flag170) 2888-- Defined in all entities. Relevant for types (and subtype) and 2889-- for objects (and enumeration literals) of a discrete type. 2890-- 2891-- The purpose of this flag is to implement the requirement stated 2892-- in (RM 13.9.1(9-11)) which require that the use of possibly invalid 2893-- values may not cause programs to become erroneous. See the function 2894-- Checks.Expr_Known_Valid for further details. Note that the setting 2895-- is conservative, in the sense that if the flag is set, it must be 2896-- right. If the flag is not set, nothing is known about the validity. 2897-- 2898-- For enumeration literals, the flag is always set, since clearly 2899-- an enumeration literal represents a valid value. Range checks 2900-- where necessary will ensure that this valid value is appropriate. 2901-- 2902-- For objects, the flag indicates the state of knowledge about the 2903-- current value of the object. This may be modified during expansion, 2904-- and thus the final value is not relevant to the backend. 2905-- 2906-- For types and subtypes, the flag is set if all possible bit patterns 2907-- of length Object_Size (i.e. Esize of the type) represent valid values 2908-- of the type. In general for such types, all values are valid, the 2909-- only exception being the case where an object of the type has an 2910-- explicit size that is greater than Object_Size. 2911-- 2912-- For non-discrete objects, the setting of the Is_Known_Valid flag is 2913-- not defined, and is not relevant, since the considerations of the 2914-- requirement in (RM 13.9.1(9-11)) do not apply. 2915-- 2916-- The flag is dynamically set and reset as semantic analysis and 2917-- expansion proceeds. Its value is meaningless once the tree is 2918-- fully constructed, since it simply indicates the last state. 2919-- Thus this flag has no meaning to the backend. 2920 2921-- Is_Limited_Composite (Flag106) 2922-- Defined in all entities. Set for composite types that have a limited 2923-- component. Used to enforce the rule that operations on the composite 2924-- type that depend on the full view of the component do not become 2925-- visible until the immediate scope of the composite type itself 2926-- (RM 7.3.1 (5)). 2927 2928-- Is_Limited_Interface (Flag197) 2929-- Defined in record types and subtypes. True for interface types, if 2930-- interface is declared limited, task, protected, or synchronized, or 2931-- is derived from a limited interface. 2932 2933-- Is_Limited_Record (Flag25) 2934-- Defined in all entities. Set to true for record (sub)types if the 2935-- record is declared to be limited. Note that this flag is not set 2936-- simply because some components of the record are limited. 2937 2938-- Is_Local_Anonymous_Access (Flag194) 2939-- Defined in access types. Set for an anonymous access type to indicate 2940-- that the type is created for a record component with an access 2941-- definition, an array component, or (pre-Ada 2012) a standalone object. 2942-- Such anonymous types have an accessibility level equal to that of the 2943-- declaration in which they appear, unlike the anonymous access types 2944-- that are created for access parameters, access discriminants, and 2945-- (as of Ada 2012) stand-alone objects. 2946 2947-- Is_Loop_Parameter (Flag307) 2948-- Applies to all entities. Certain loops, in particular "for ... of" 2949-- loops, get transformed so that the loop parameter is declared by a 2950-- variable declaration, so the entity is an E_Variable. This is True for 2951-- such E_Variables; False otherwise. 2952 2953-- Is_Machine_Code_Subprogram (Flag137) 2954-- Defined in subprogram entities. Set to indicate that the subprogram 2955-- is a machine code subprogram (i.e. its body includes at least one 2956-- code statement). Also indicates that all necessary semantic checks 2957-- as required by RM 13.8(3) have been performed. 2958 2959-- Is_Modular_Integer_Type (synthesized) 2960-- Applies to all entities. True if entity is a modular integer type 2961 2962-- Is_Non_Static_Subtype (Flag109) 2963-- Defined in all type and subtype entities. It is set in some (but not 2964-- all) cases in which a subtype is known to be non-static. Before this 2965-- flag was added, the computation of whether a subtype was static was 2966-- entirely synthesized, by looking at the bounds, and the immediate 2967-- subtype parent. However, this method does not work for some Itypes 2968-- that have no parent set (and the only way to find the immediate 2969-- subtype parent is to go through the tree). For now, this flag is set 2970-- conservatively, i.e. if it is set then for sure the subtype is non- 2971-- static, but if it is not set, then the type may or may not be static. 2972-- Thus the test for a static subtype is that this flag is clear AND that 2973-- the bounds are static AND that the parent subtype (if available to be 2974-- tested) is static. Eventually we should make sure this flag is always 2975-- set right, at which point, these comments can be removed, and the 2976-- tests for static subtypes greatly simplified. 2977 2978-- Is_Null_Init_Proc (Flag178) 2979-- Defined in procedure entities. Set for generated init proc procedures 2980-- (used to initialize composite types), if the code for the procedure 2981-- is null (i.e. is a return and nothing else). Such null initialization 2982-- procedures are generated in case some client is compiled using the 2983-- Initialize_Scalars pragma, generating a call to this null procedure, 2984-- but there is no need to call such procedures within a compilation 2985-- unit, and this flag is used to suppress such calls. 2986 2987-- Is_Null_State (synthesized) 2988-- Applies to all entities, true for an abstract state declared with 2989-- keyword null. 2990 2991-- Is_Numeric_Type (synthesized) 2992-- Applies to all entities, true for all numeric types and subtypes 2993-- (integer, fixed, float). 2994 2995-- Is_Object (synthesized) 2996-- Applies to all entities, true for entities representing objects, 2997-- including generic formal parameters. 2998 2999-- Is_Obsolescent (Flag153) 3000-- Defined in all entities. Set for any entity to which a valid pragma 3001-- or aspect Obsolescent applies. 3002 3003-- Is_Only_Out_Parameter (Flag226) 3004-- Defined in formal parameter entities. Set if this parameter is the 3005-- only OUT parameter for this formal part. If there is more than one 3006-- out parameter, or if there is some other IN OUT parameter then this 3007-- flag is not set in any of them. Used in generation of warnings. 3008 3009-- Is_Ordinary_Fixed_Point_Type (synthesized) 3010-- Applies to all entities, true for ordinary fixed point types and 3011-- subtypes. 3012 3013-- Is_Package_Body_Entity (Flag160) 3014-- Defined in all entities. Set for entities defined at the top level 3015-- of a package body. Used to control externally generated names. 3016 3017-- Is_Package_Or_Generic_Package (synthesized) 3018-- Applies to all entities. True for packages and generic packages. 3019-- False for all other entities. 3020 3021-- Is_Packed (Flag51) [implementation base type only] 3022-- Defined in all type entities. This flag is set only for record and 3023-- array types which have a packed representation. There are four cases 3024-- which cause packing: 3025-- 3026-- 1. Explicit use of pragma Pack to pack a record. 3027-- 2. Explicit use of pragma Pack to pack an array. 3028-- 3. Setting Component_Size of an array to a packable value. 3029-- 4. Indexing an array with a non-standard enumeration type. 3030-- 3031-- For records, Is_Packed is always set if Has_Pragma_Pack is set, and 3032-- can also be set on its own in a derived type which inherited its 3033-- packed status. 3034-- 3035-- For arrays, Is_Packed is set if either Has_Pragma_Pack is set and the 3036-- component size is either not known at compile time or known but not 3037-- 8/16/32/64 bits, or a Component_Size clause exists and the specified 3038-- value is smaller than 64 bits but not 8/16/32, or if the array has one 3039-- or more index types that are enumeration types with a non-standard 3040-- representation (in GNAT, we store such arrays compactly, using the Pos 3041-- of the enumeration type value). As for the case of records, Is_Packed 3042-- can be set on its own for a derived type. 3043 3044-- Before an array type is frozen, Is_Packed will always be set if 3045-- Has_Pragma_Pack is set. Before the freeze point, it is not possible 3046-- to know the component size, since the component type is not frozen 3047-- until the array type is frozen. Thus Is_Packed for an array type 3048-- before it is frozen means that packed is required. Then if it turns 3049-- out that the component size doesn't require packing, the Is_Packed 3050-- flag gets turned off. 3051 3052-- In the bit-packed array case (i.e. the component size is known by the 3053-- front end and is in the range 1-63 but not a multiple of 8), then the 3054-- Is_Bit_Packed_Array flag will be set once the array type is frozen. 3055-- 3056-- Is_Packed_Array (synth) 3057-- Applies to all entities, true if entity is for a packed array. 3058 3059-- Is_Packed_Array_Impl_Type (Flag138) 3060-- Defined in all entities. This flag is set on the entity for the type 3061-- used to implement a packed array (either a modular type or a subtype 3062-- of Packed_Bytes{1,2,4} in the bit-packed array case, a regular array 3063-- in the non-standard enumeration index case). It is set if and only 3064-- if the type appears in the Packed_Array_Impl_Type field of some other 3065-- entity. It is used by the back end to activate the special processing 3066-- for such types (unchecked conversions that would not otherwise be 3067-- allowed are allowed for such types). If Is_Packed_Array_Impl_Type is 3068-- set in an entity, then the Original_Array_Type field of this entity 3069-- points to the array type for which this is the Packed_Array_Impl_Type. 3070 3071-- Is_Param_Block_Component_Type (Flag215) [base type only] 3072-- Defined in access types. Set to indicate that a type is the type of a 3073-- component of the parameter block record type generated by the compiler 3074-- for an entry or a select statement. Read by CodePeer. 3075 3076-- Is_Partial_Invariant_Procedure (Flag292) 3077-- Defined in functions and procedures. Set for a generated invariant 3078-- procedure which verifies the invariants of the partial view of a 3079-- private type or private extension. 3080 3081-- Is_Potentially_Use_Visible (Flag9) 3082-- Defined in all entities. Set if entity is potentially use visible, 3083-- i.e. it is defined in a package that appears in a currently active 3084-- use clause (RM 8.4(8)). Note that potentially use visible entities 3085-- are not necessarily use visible (RM 8.4(9-11)). 3086 3087-- Is_Predicate_Function (Flag255) 3088-- Present in functions and procedures. Set for generated predicate 3089-- functions. 3090 3091-- Is_Predicate_Function_M (Flag256) 3092-- Present in functions and procedures. Set for special version of 3093-- predicate function generated for use in membership tests, where 3094-- raise expressions are transformed to return False. 3095 3096-- Is_Preelaborated (Flag59) 3097-- Defined in all entities, set in E_Package and E_Generic_Package 3098-- entities to which a pragma Preelaborate is applied, and also in 3099-- all entities within such packages. Note that the fact that this 3100-- flag is set does not necesarily mean that no elaboration code is 3101-- generated for the package. 3102 3103-- Is_Primitive (Flag218) 3104-- Defined in overloadable entities and in generic subprograms. Set to 3105-- indicate that this is a primitive operation of some type, which may 3106-- be a tagged type or an untagged type. Used to verify overriding 3107-- indicators in bodies. 3108 3109-- Is_Primitive_Wrapper (Flag195) 3110-- Defined in functions and procedures created by the expander to serve 3111-- as an indirection mechanism to overriding primitives of concurrent 3112-- types, entries and protected procedures. 3113 3114-- Is_Prival (synthesized) 3115-- Applies to all entities, true for renamings of private protected 3116-- components. Such entities appear as constants or variables. 3117 3118-- Is_Private_Composite (Flag107) 3119-- Defined in composite types that have a private component. Used to 3120-- enforce the rule that operations on the composite type that depend 3121-- on the full view of the component, do not become visible until the 3122-- immediate scope of the composite type itself (7.3.1 (5)). Both this 3123-- flag and Is_Limited_Composite are needed. 3124 3125-- Is_Private_Descendant (Flag53) 3126-- Defined in entities that can represent library units (packages, 3127-- functions, procedures). Set if the library unit is itself a private 3128-- child unit, or if it is the descendant of a private child unit. 3129 3130-- Is_Private_Primitive (Flag245) 3131-- Defined in subprograms. Set if the operation is a primitive of a 3132-- tagged type (procedure or function dispatching on result) whose 3133-- full view has not been seen. Used in particular for primitive 3134-- subprograms of a synchronized type declared between the two views 3135-- of the type, so that the wrapper built for such a subprogram can 3136-- be given the proper signature. 3137 3138-- Is_Private_Type (synthesized) 3139-- Applies to all entities, true for private types and subtypes, 3140-- as well as for record with private types as subtypes. 3141 3142-- Is_Protected_Component (synthesized) 3143-- Applicable to all entities, true if the entity denotes a private 3144-- component of a protected type. 3145 3146-- Is_Protected_Interface (synthesized) 3147-- Defined in types that are interfaces. True if interface is declared 3148-- protected, or is derived from protected interfaces. 3149 3150-- Is_Protected_Record_Type (synthesized) 3151-- Applies to all entities, true if Is_Concurrent_Record_Type is true and 3152-- Corresponding_Concurrent_Type is a protected type. 3153 3154-- Is_Protected_Type (synthesized) 3155-- Applies to all entities, true for protected types and subtypes 3156 3157-- Is_Public (Flag10) 3158-- Defined in all entities. Set to indicate that an entity defined in 3159-- one compilation unit can be referenced from other compilation units. 3160-- If this reference causes a reference in the generated code, for 3161-- example in the case of a variable name, then the backend will generate 3162-- an appropriate external name for use by the linker. 3163 3164-- Is_Pure (Flag44) 3165-- Defined in all entities. Set in all entities of a unit to which a 3166-- pragma Pure is applied except for non-intrinsic imported subprograms, 3167-- and also set for the entity of the unit itself. In addition, this 3168-- flag may be set for any other functions or procedures that are known 3169-- to be side effect free, so in the case of subprograms, the Is_Pure 3170-- flag may be used by the optimizer to imply that it can assume freedom 3171-- from side effects (other than those resulting from assignment to Out 3172-- or In Out parameters, or to objects designated by access parameters). 3173 3174-- Is_Pure_Unit_Access_Type (Flag189) 3175-- Defined in access type and subtype entities. Set if the type or 3176-- subtype appears in a pure unit. Used to give an error message at 3177-- freeze time if the access type has a storage pool. 3178 3179-- Is_RACW_Stub_Type (Flag244) 3180-- Defined in all types, true for the stub types generated for remote 3181-- access-to-class-wide types. 3182 3183-- Is_Raised (Flag224) 3184-- Defined in exception entities. Set if the entity is referenced by a 3185-- a raise statement. 3186 3187-- Is_Real_Type (synthesized) 3188-- Applies to all entities, true for real types and subtypes 3189 3190-- Is_Record_Type (synthesized) 3191-- Applies to all entities, true for record types and subtypes, 3192-- includes class-wide types and subtypes (which are also records). 3193 3194-- Is_Relaxed_Initialization_State (synthesized) 3195-- Applies to all entities, true for abstract states that are subject to 3196-- option Relaxed_Initialization. 3197 3198-- Is_Remote_Call_Interface (Flag62) 3199-- Defined in all entities. Set in E_Package and E_Generic_Package 3200-- entities to which a pragma Remote_Call_Interface is applied, and 3201-- also on entities declared in the visible part of such a package. 3202 3203-- Is_Remote_Types (Flag61) 3204-- Defined in all entities. Set in E_Package and E_Generic_Package 3205-- entities to which a pragma Remote_Types is applied, and also on 3206-- entities declared in the visible part of the spec of such a package. 3207-- Also set for types which are generic formal types to which the 3208-- pragma Remote_Access_Type applies. 3209 3210-- Is_Renaming_Of_Object (Flag112) 3211-- Defined in all entities, set only for a variable or constant for 3212-- which the Renamed_Object field is non-empty and for which the 3213-- renaming is handled by the front end, by macro substitution of 3214-- a copy of the (evaluated) name tree whereever the variable is used. 3215 3216-- Is_Return_Object (Flag209) 3217-- Defined in all object entities. True if the object is the return 3218-- object of an extended_return_statement; False otherwise. 3219 3220-- Is_Safe_To_Reevaluate (Flag249) 3221-- Defined in all entities. Set in variables that are initialized by 3222-- means of an assignment statement. When initialized their contents 3223-- never change and hence they can be seen by the backend as constants. 3224-- See also Is_True_Constant. 3225 3226-- Is_Scalar_Type (synthesized) 3227-- Applies to all entities, true for scalar types and subtypes 3228 3229-- Is_Shared_Passive (Flag60) 3230-- Defined in all entities. Set in E_Package and E_Generic_Package 3231-- entities to which a pragma Shared_Passive is applied, and also in 3232-- all entities within such packages. 3233 3234-- Is_Standard_Character_Type (synthesized) 3235-- Applies to all entities, true for types and subtypes whose root type 3236-- is one of the standard character types (Character, Wide_Character, or 3237-- Wide_Wide_Character). 3238 3239-- Is_Standard_String_Type (synthesized) 3240-- Applies to all entities, true for types and subtypes whose root 3241-- type is one of the standard string types (String, Wide_String, or 3242-- Wide_Wide_String). 3243 3244-- Is_Static_Type (Flag281) 3245-- Defined in entities. Only set for (sub)types. If set, indicates that 3246-- the type is known to be a static type (defined as a discrete type with 3247-- static bounds, a record all of whose component types are static types, 3248-- or an array, all of whose bounds are of a static type, and also have 3249-- a component type that is a static type). See Set_Uplevel_Type for more 3250-- information on how this flag is used. 3251 3252-- Is_Statically_Allocated (Flag28) 3253-- Defined in all entities. This can only be set for exception, 3254-- variable, constant, and type/subtype entities. If the flag is set, 3255-- then the variable or constant must be allocated statically rather 3256-- than on the local stack frame. For exceptions, the meaning is that 3257-- the exception data should be allocated statically (and indeed this 3258-- flag is always set for exceptions, since exceptions do not have 3259-- local scope). For a type, the meaning is that the type must be 3260-- elaborated at the global level rather than locally. No type marked 3261-- with this flag may depend on a local variable, or on any other type 3262-- which does not also have this flag set to True. For a variable or 3263-- or constant, if the flag is set, then the type of the object must 3264-- either be declared at the library level, or it must also have the 3265-- flag set (since to allocate the object statically, its type must 3266-- also be elaborated globally). 3267 3268-- Is_String_Type (synthesized) 3269-- Applies to all type entities. Determines if the given type is a 3270-- string type, i.e. it is directly a string type or string subtype, 3271-- or a string slice type, or an array type with one dimension and a 3272-- component type that is a character type. 3273 3274-- Is_Subprogram (synthesized) 3275-- Applies to all entities, true for function, procedure and operator 3276-- entities. 3277 3278-- Is_Subprogram_Or_Generic_Subprogram 3279-- Applies to all entities, true for function procedure and operator 3280-- entities, and also for the corresponding generic entities. 3281 3282-- Is_Synchronized_Interface (synthesized) 3283-- Defined in types that are interfaces. True if interface is declared 3284-- synchronized, task, or protected, or is derived from a synchronized 3285-- interface. 3286 3287-- Is_Synchronized_State (synthesized) 3288-- Applies to all entities, true for abstract states that are subject to 3289-- option Synchronous. 3290 3291-- Is_Tag (Flag78) 3292-- Defined in E_Component and E_Constant entities. For regular tagged 3293-- type this flag is set on the tag component (whose name is Name_uTag). 3294-- For CPP_Class tagged types, this flag marks the pointer to the main 3295-- vtable (i.e. the one to be extended by derivation). 3296 3297-- Is_Tagged_Type (Flag55) 3298-- Defined in all entities, set for an entity that is a tagged type 3299 3300-- Is_Task_Interface (synthesized) 3301-- Defined in types that are interfaces. True if interface is declared as 3302-- a task interface, or if it is derived from task interfaces. 3303 3304-- Is_Task_Record_Type (synthesized) 3305-- Applies to all entities, true if Is_Concurrent_Record_Type is true and 3306-- Corresponding_Concurrent_Type is a task type. 3307 3308-- Is_Task_Type (synthesized) 3309-- Applies to all entities. True for task types and subtypes 3310 3311-- Is_Thunk (Flag225) 3312-- Defined in all entities. True for subprograms that are thunks: that is 3313-- small subprograms built by the expander for tagged types that cover 3314-- interface types. As part of the runtime call to an interface, thunks 3315-- displace the pointer to the object (pointer named "this" in the C++ 3316-- terminology) from a secondary dispatch table to the primary dispatch 3317-- table associated with a given tagged type; if the thunk is a function 3318-- that returns an object which covers an interface type then the thunk 3319-- displaces the pointer to the object from the primary dispatch table to 3320-- the secondary dispatch table associated with the interface type. Set 3321-- by Expand_Interface_Thunk and used by Expand_Call to handle extra 3322-- actuals associated with accessibility level. 3323 3324-- Is_Trivial_Subprogram (Flag235) 3325-- Defined in all entities. Set in subprograms where either the body 3326-- consists of a single null statement, or the first or only statement 3327-- of the body raises an exception. This is used for suppressing certain 3328-- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details. 3329 3330-- Is_True_Constant (Flag163) 3331-- Defined in all entities for constants and variables. Set in constants 3332-- and variables which have an initial value specified but which are 3333-- never assigned, partially or in the whole. For variables, it means 3334-- that the variable was initialized but never modified, and hence can be 3335-- treated as a constant by the code generator. For a constant, it means 3336-- that the constant was not modified by generated code (e.g. to set a 3337-- discriminant in an init proc). Assignments by user or generated code 3338-- will reset this flag. See also Is_Safe_To_Reevaluate. 3339 3340-- Is_Type (synthesized) 3341-- Applies to all entities, true for a type entity 3342 3343-- Is_Unchecked_Union (Flag117) [implementation base type only] 3344-- Defined in all entities. Set only in record types to which the 3345-- pragma Unchecked_Union has been validly applied. 3346 3347-- Is_Underlying_Full_View (Flag298) 3348-- Defined in all entities. Set for types which represent the true full 3349-- view of a private type completed by another private type. For further 3350-- details, see attribute Underlying_Full_View. 3351 3352-- Is_Underlying_Record_View (Flag246) [base type only] 3353-- Defined in all entities. Set only in record types that represent the 3354-- underlying record view. This view is built for derivations of types 3355-- with unknown discriminants; it is a record with the same structure 3356-- as its corresponding record type, but whose parent is the full view 3357-- of the parent in the original type extension. 3358 3359-- Is_Unimplemented (Flag284) 3360-- Defined in all entities. Set for any entity to which a valid pragma 3361-- or aspect Unimplemented applies. 3362 3363-- Is_Unsigned_Type (Flag144) 3364-- Defined in all types, but can be set only for discrete and fixed-point 3365-- type and subtype entities. This flag is only valid if the entity is 3366-- frozen. If set it indicates that the representation is known to be 3367-- unsigned (i.e. that no negative values appear in the range). This is 3368-- normally just a reflection of the lower bound of the subtype or base 3369-- type, but there is one case in which the setting is not obvious, 3370-- namely the case of an unsigned subtype of a signed type from which 3371-- a further subtype is obtained using variable bounds. This further 3372-- subtype is still unsigned, but this cannot be determined by looking 3373-- at its bounds or the bounds of the corresponding base type. 3374-- For a subtype indication whose range is statically a null range, 3375-- the flag is set if the lower bound is non-negative, but the flag 3376-- cannot be used to determine the comparison operator to emit in the 3377-- generated code: use the base type. 3378 3379-- Is_Uplevel_Referenced_Entity (Flag283) 3380-- Defined in all entities. Used when unnesting subprograms to indicate 3381-- that an entity is locally defined within a subprogram P, and there is 3382-- a reference to the entity within a subprogram nested within P (at any 3383-- depth). Set for uplevel referenced objects (variables, constants, 3384-- discriminants and loop parameters), and also for upreferenced dynamic 3385-- types, including the cases where the reference is implicit (e.g. the 3386-- type of an array used for computing the location of an element in an 3387-- array. This is used internally in Exp_Unst, see this package for 3388-- further details. 3389 3390-- Is_Valued_Procedure (Flag127) 3391-- Defined in procedure entities. Set if an Import_Valued_Procedure 3392-- or Export_Valued_Procedure pragma applies to the procedure entity. 3393 3394-- Is_Visible_Formal (Flag206) 3395-- Defined in all entities. Set for instances of the formals of a 3396-- formal package. Indicates that the entity must be made visible in the 3397-- body of the instance, to reproduce the visibility of the generic. 3398-- This simplifies visibility settings in instance bodies. 3399 3400-- Is_Visible_Lib_Unit (Flag116) 3401-- Defined in all (root or child) library unit entities. Once compiled, 3402-- library units remain chained to the entities in the parent scope, and 3403-- a separate flag must be used to indicate whether the names are visible 3404-- by selected notation, or not. 3405 3406-- Is_Volatile (Flag16) 3407-- Defined in all type entities, and also in constants, components and 3408-- variables. Set if a pragma Volatile applies to the entity. Also set 3409-- if pragma Shared or pragma Atomic applies to entity. In the case of 3410-- private or incomplete types, this flag is set in both the private 3411-- and full view. The flag is not set reliably on private subtypes, 3412-- and is always retrieved from the base type (but this is not a base- 3413-- type-only attribute because it applies to other entities). Note that 3414-- the backend should use Treat_As_Volatile, rather than Is_Volatile 3415-- to indicate code generation requirements for volatile variables. 3416-- Similarly, any front end test which is concerned with suppressing 3417-- optimizations on volatile objects should test Treat_As_Volatile 3418-- rather than testing this flag. 3419 3420-- Is_Volatile_Full_Access (Flag285) 3421-- Defined in all type entities, and also in constants, components, and 3422-- variables. Set if an aspect/pragma Volatile_Full_Access or an Ada 2020 3423-- aspect Full_Access_Only applies to the entity. In the case of private 3424-- and incomplete types, this flag is set in both the partial view and 3425-- the full view. 3426 3427-- Is_Wrapper_Package (synthesized) 3428-- Defined in package entities. Indicates that the package has been 3429-- created as a wrapper for a subprogram instantiation. 3430 3431-- Itype_Printed (Flag202) 3432-- Defined in all type and subtype entities. Set in Itypes if the Itype 3433-- has been printed by Sprint. This is used to avoid printing an Itype 3434-- more than once. 3435 3436-- Kill_Elaboration_Checks (Flag32) 3437-- Defined in all entities. Set by the expander to kill elaboration 3438-- checks which are known not to be needed. Equivalent in effect to 3439-- the use of pragma Suppress (Elaboration_Checks) for that entity 3440-- except that the effect is permanent and cannot be undone by a 3441-- subsequent pragma Unsuppress. 3442 3443-- Kill_Range_Checks (Flag33) 3444-- Defined in all entities. Equivalent in effect to the use of pragma 3445-- Suppress (Range_Checks) for that entity except that the result is 3446-- permanent and cannot be undone by a subsequent pragma Unsuppress. 3447-- This is currently only used in one odd situation in Sem_Ch3 for 3448-- record types, and it would be good to get rid of it??? 3449 3450-- Known_To_Have_Preelab_Init (Flag207) 3451-- Defined in all type and subtype entities. If set, then the type is 3452-- known to have preelaborable initialization. In the case of a partial 3453-- view of a private type, it is only possible for this to be set if a 3454-- pragma Preelaborable_Initialization is given for the type. For other 3455-- types, it is never set if the type does not have preelaborable 3456-- initialization, it may or may not be set if the type does have 3457-- preelaborable initialization. 3458 3459-- Last_Aggregate_Assignment (Node30) 3460-- Applies to controlled constants and variables initialized by an 3461-- aggregate. Points to the last statement associated with the expansion 3462-- of the aggregate. The attribute is used by the finalization machinery 3463-- when marking an object as successfully initialized. 3464 3465-- Last_Assignment (Node26) 3466-- Defined in entities for variables, and OUT or IN OUT formals. Set for 3467-- a local variable or formal to point to the left side of an assignment 3468-- statement assigning a value to the variable. Cleared if the value of 3469-- the entity is referenced. Used to warn about dubious assignment 3470-- statements whose value is not used. 3471 3472-- Last_Entity (Node20) 3473-- Defined in all entities which act as scopes to which a list of 3474-- associated entities is attached (blocks, class subtypes and types, 3475-- entries, functions, loops, packages, procedures, protected objects, 3476-- record types and subtypes, private types, task types and subtypes). 3477-- Points to the last entry in the list of associated entities chained 3478-- through the Next_Entity field. Empty if no entities are chained. 3479 3480-- Last_Formal (synthesized) 3481-- Applies to subprograms and subprogram types, and also in entries 3482-- and entry families. Returns last formal of the subprogram or entry. 3483-- The formals are the first entities declared in a subprogram or in 3484-- a subprogram type (the designated type of an Access_To_Subprogram 3485-- definition) or in an entry. 3486 3487-- Limited_View (Node23) 3488-- Defined in non-generic package entities that are not instances. Bona 3489-- fide package with the limited-view list through the first_entity and 3490-- first_private attributes. The elements of this list are the shadow 3491-- entities created for the types and local packages that are declared 3492-- in a package appearing in a limited_with clause (Ada 2005: AI-50217). 3493 3494-- Linker_Section_Pragma (Node33) 3495-- Present in constant, variable, type and subprogram entities. Points 3496-- to a linker section pragma that applies to the entity, or is Empty if 3497-- no such pragma applies. Note that for constants and variables, this 3498-- field may be set as a result of a linker section pragma applied to the 3499-- type of the object. 3500 3501-- Lit_Indexes (Node18) 3502-- Defined in enumeration types and subtypes. Non-empty only for the 3503-- case of an enumeration root type, where it contains the entity for 3504-- the generated indexes entity. See unit Exp_Imgv for full details of 3505-- the nature and use of this entity for implementing the Image and 3506-- Value attributes for the enumeration type in question. 3507 3508-- Lit_Strings (Node16) 3509-- Defined in enumeration types and subtypes. Non-empty only for the 3510-- case of an enumeration root type, where it contains the entity for 3511-- the literals string entity. See unit Exp_Imgv for full details of 3512-- the nature and use of this entity for implementing the Image and 3513-- Value attributes for the enumeration type in question. 3514 3515-- Low_Bound_Tested (Flag205) 3516-- Defined in all entities. Currently this can only be set for formal 3517-- parameter entries of a standard unconstrained one-dimensional array 3518-- or string type. Indicates that an explicit test of the low bound of 3519-- the formal appeared in the code, e.g. in a pragma Assert. If this 3520-- flag is set, warnings about assuming the index low bound to be one 3521-- are suppressed. 3522 3523-- Machine_Radix_10 (Flag84) 3524-- Defined in decimal types and subtypes, set if the Machine_Radix is 10, 3525-- as the result of the specification of a machine radix representation 3526-- clause. Note that it is possible for this flag to be set without 3527-- having Has_Machine_Radix_Clause True. This happens when a type is 3528-- derived from a type with a clause present. 3529 3530-- Master_Id (Node17) 3531-- Defined in access types and subtypes. Empty unless Has_Task is set for 3532-- the designated type, in which case it points to the entity for the 3533-- Master_Id for the access type master. Also set for access-to-limited- 3534-- class-wide types whose root may be extended with task components, and 3535-- for access-to-limited-interfaces because they can be used to reference 3536-- tasks implementing such interface. 3537 3538-- Materialize_Entity (Flag168) 3539-- Defined in all entities. Set only for renamed obects which should be 3540-- materialized for debugging purposes. This means that a memory location 3541-- containing the renamed address should be allocated. This is needed so 3542-- that the debugger can find the entity. 3543 3544-- May_Inherit_Delayed_Rep_Aspects (Flag262) 3545-- Defined in all entities for types and subtypes. Set if the type is 3546-- derived from a type which has delayed rep aspects (marked by the flag 3547-- Has_Delayed_Rep_Aspects being set). In this case, at the freeze point 3548-- for the derived type we know that the parent type is frozen, and if 3549-- a given attribute has not been set for the derived type, we copy the 3550-- value from the parent type. See Freeze.Inherit_Delayed_Rep_Aspects. 3551 3552-- Mechanism (Uint8) (returned as Mechanism_Type) 3553-- Defined in functions and non-generic formal parameters. Indicates 3554-- the mechanism to be used for the function return or for the formal 3555-- parameter. See full description in the spec of Sem_Mech. This field 3556-- is also set (to the default value of zero = Default_Mechanism) in a 3557-- subprogram body entity but not used in this context. 3558 3559-- Minimum_Accessibility (Node24) 3560-- Defined in formal parameters in the non-generic case. Normally Empty, 3561-- but if expansion is active, and a parameter exists for which a 3562-- dynamic accessibility check is required, then an object is generated 3563-- within such a subprogram representing the accessibility level of the 3564-- subprogram or the formal's Extra_Accessibility - whichever one is 3565-- lesser. The Minimum_Accessibility field then points to this object. 3566 3567-- Modulus (Uint17) [base type only] 3568-- Defined in modular types. Contains the modulus. For the binary case, 3569-- this will be a power of 2, but if Non_Binary_Modulus is set, then it 3570-- will not be a power of 2. 3571 3572-- Must_Be_On_Byte_Boundary (Flag183) 3573-- Defined in entities for types and subtypes. Set if objects of the type 3574-- must always be allocated on a byte boundary (more accurately a storage 3575-- unit boundary). The front end checks that component clauses respect 3576-- this rule, and the backend ensures that record packing does not 3577-- violate this rule. Currently the flag is set only for packed arrays 3578-- longer than 64 bits where the component size is not a power of 2. 3579 3580-- Must_Have_Preelab_Init (Flag208) 3581-- Defined in entities for types and subtypes. Set in the full type of a 3582-- private type or subtype if a pragma Has_Preelaborable_Initialization 3583-- is present for the private type. Used to check that the full type has 3584-- preelaborable initialization at freeze time (this has to be deferred 3585-- to the freeze point because of the rule about overriding Initialize). 3586 3587-- Needs_Activation_Record (Flag306) 3588-- Defined on generated subprogram types. Indicates that a call through 3589-- a named or anonymous access to subprogram requires an activation 3590-- record when compiling with unnesting for C or LLVM. 3591 3592-- Needs_Debug_Info (Flag147) 3593-- Defined in all entities. Set if the entity requires normal debugging 3594-- information to be generated. This is true of all entities that have 3595-- Comes_From_Source set, and also transitively for entities associated 3596-- with such components (e.g. their types). It is true for all entities 3597-- in Debug_Generated_Code mode (-gnatD switch). This is the flag that 3598-- the backend should check to determine whether or not to generate 3599-- debugging information for an entity. Note that callers should always 3600-- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info, 3601-- so that the flag is set properly on subsidiary entities. 3602 3603-- Needs_No_Actuals (Flag22) 3604-- Defined in callable entities (subprograms, entries, access to 3605-- subprograms) which can be called without actuals because all of 3606-- their formals (if any) have default values. This flag simplifies the 3607-- resolution of the syntactic ambiguity involving a call to these 3608-- entities when the return type is an array type, and a call can be 3609-- interpreted as an indexing of the result of the call. It is also 3610-- used to resolve various cases of entry calls. 3611 3612-- Never_Set_In_Source (Flag115) 3613-- Defined in all entities, but can be set only for variables and 3614-- parameters. This flag is set if the object is never assigned a value 3615-- in user source code, either by assignment or by being used as an out 3616-- or in out parameter. Note that this flag is not reset from using an 3617-- initial value, so if you want to test for this case as well, test the 3618-- Has_Initial_Value flag also. 3619-- 3620-- This flag is only for the purposes of issuing warnings, it must not 3621-- be used by the code generator to indicate that the variable is in 3622-- fact a constant, since some assignments in generated code do not 3623-- count (for example, the call to an init proc to assign some but 3624-- not all of the fields in a partially initialized record). The code 3625-- generator should instead use the flag Is_True_Constant. 3626-- 3627-- For the purposes of this warning, the default assignment of access 3628-- variables to null is not considered the assignment of a value (so 3629-- the warning can be given for code that relies on this initial null 3630-- value when no other value is ever set). 3631-- 3632-- In variables and out parameters, if this flag is set after full 3633-- processing of the corresponding declarative unit, it indicates that 3634-- the variable or parameter was never set, and a warning message can 3635-- be issued. 3636-- 3637-- Note: this flag is initially set, and then cleared on encountering 3638-- any construct that might conceivably legitimately set the value. 3639-- Thus during the analysis of a declarative region and its associated 3640-- statement sequence, the meaning of the flag is "not set yet", and 3641-- once this analysis is complete the flag means "never assigned". 3642 3643-- Note: for variables appearing in package declarations, this flag is 3644-- never set. That is because there is no way to tell if some client 3645-- modifies the variable (or, in the case of variables in the private 3646-- part, if some child unit modifies the variables). 3647 3648-- Note: in the case of renamed objects, the flag must be set in the 3649-- ultimate renamed object. Clients noting a possible modification 3650-- should use the Note_Possible_Modification procedure in Sem_Util 3651-- rather than Set_Never_Set_In_Source precisely to deal properly with 3652-- the renaming possibility. 3653 3654-- Next_Component (synthesized) 3655-- Applies to record components. Returns the next component by following 3656-- the chain of declared entities until one is found which corresponds to 3657-- a component (Ekind is E_Component). Any internal types generated from 3658-- the subtype indications of the record components are skipped. Returns 3659-- Empty if no more components. 3660 3661-- Next_Component_Or_Discriminant (synthesized) 3662-- Similar to Next_Component, but includes components and discriminants 3663-- so the input can have either E_Component or E_Discriminant, and the 3664-- same is true for the result. Returns Empty if no more components or 3665-- discriminants in the record. 3666 3667-- Next_Discriminant (synthesized) 3668-- Applies to discriminants returned by First/Next_Discriminant. Returns 3669-- the next language-defined (i.e. perhaps non-girder) discriminant by 3670-- following the chain of declared entities as long as the kind of the 3671-- entity corresponds to a discriminant. Note that the discriminants 3672-- might be the only components of the record. Returns Empty if there 3673-- are no more discriminants. 3674 3675-- Next_Entity (Node2) 3676-- Defined in all entities. The entities of a scope are chained, with 3677-- the head of the list being in the First_Entity field of the scope 3678-- entity. All entities use the Next_Entity field as a forward pointer 3679-- for this list, with Empty indicating the end of the list. Since this 3680-- field is in the base part of the entity, the access routines for this 3681-- field are in Sinfo. 3682 3683-- Next_Formal (synthesized) 3684-- Applies to the entity for a formal parameter. Returns the next formal 3685-- parameter of the subprogram or subprogram type. Returns Empty if there 3686-- are no more formals. 3687 3688-- Next_Formal_With_Extras (synthesized) 3689-- Applies to the entity for a formal parameter. Returns the next 3690-- formal parameter of the subprogram or subprogram type. Returns 3691-- Empty if there are no more formals. The list returned includes 3692-- all the extra formals (see description of Extra_Formal field) 3693 3694-- Next_Index (synthesized) 3695-- Applies to array types and subtypes and to string types and 3696-- subtypes. Yields the next index. The first index is obtained by 3697-- using the First_Index attribute, and then subsequent indexes are 3698-- obtained by applying Next_Index to the previous index. Empty is 3699-- returned to indicate that there are no more indexes. Note that 3700-- unlike most attributes in this package, Next_Index applies to 3701-- nodes for the indexes, not to entities. 3702 3703-- Next_Inlined_Subprogram (Node12) 3704-- Defined in subprograms. Used to chain inlined subprograms used in 3705-- the current compilation, in the order in which they must be compiled 3706-- by the backend to ensure that all inlinings are performed. 3707 3708-- Next_Literal (synthesized) 3709-- Applies to enumeration literals, returns the next literal, or 3710-- Empty if applied to the last literal. This is actually a synonym 3711-- for Next, but its use is preferred in this context. 3712 3713-- No_Dynamic_Predicate_On_Actual (Flag276) 3714-- Defined in discrete types. Set for generic formal types that are used 3715-- in loops and quantified expressions. The corresponing actual cannot 3716-- have dynamic predicates. 3717 3718-- No_Pool_Assigned (Flag131) [root type only] 3719-- Defined in access types. Set if a storage size clause applies to the 3720-- variable with a static expression value of zero. This flag is used to 3721-- generate errors if any attempt is made to allocate or free an instance 3722-- of such an access type. This is set only in the root type, since 3723-- derived types must have the same pool. 3724 3725-- No_Predicate_On_Actual (Flag275) 3726-- Defined in discrete types. Set for generic formal types that are used 3727-- in the spec of a generic package, in constructs that forbid discrete 3728-- types with predicates. 3729 3730-- No_Reordering (Flag239) [implementation base type only] 3731-- Defined in record types. Set only for a base type to which a valid 3732-- pragma No_Component_Reordering applies. 3733 3734-- No_Return (Flag113) 3735-- Defined in all entities. Set for subprograms and generic subprograms 3736-- to which a valid aspect or pragma No_Return applies. 3737 3738-- No_Strict_Aliasing (Flag136) [base type only] 3739-- Defined in access types. Set to direct the backend to avoid any 3740-- optimizations based on an assumption about the aliasing status of 3741-- objects designated by the access type. For the case of the gcc 3742-- backend, the effect is as though all references to objects of 3743-- the type were compiled with -fno-strict-aliasing. This flag is 3744-- set if an unchecked conversion with the access type as a target 3745-- type occurs in the same source unit as the declaration of the 3746-- access type, or if an explicit pragma No_Strict_Aliasing applies. 3747 3748-- No_Tagged_Streams_Pragma (Node32) 3749-- Present in all subtype and type entities. Set for tagged types and 3750-- subtypes (i.e. entities with Is_Tagged_Type set True) if a valid 3751-- pragma/aspect applies to the type. 3752 3753-- Non_Binary_Modulus (Flag58) [base type only] 3754-- Defined in all subtype and type entities. Set for modular integer 3755-- types if the modulus value is other than a power of 2. 3756 3757-- Non_Limited_View (Node19) 3758-- Defined in abstract states and incomplete types that act as shadow 3759-- entities created when analysing a limited with clause (Ada 2005: 3760-- AI-50217). Points to the defining entity of the original declaration. 3761 3762-- Nonzero_Is_True (Flag162) [base type only] 3763-- Defined in enumeration types. Set if any non-zero value is to be 3764-- interpreted as true. Currently this is set for derived Boolean 3765-- types which have a convention of C, C++ or Fortran. 3766 3767-- Normalized_First_Bit (Uint8) 3768-- Defined in components and discriminants. Indicates the normalized 3769-- value of First_Bit for the component, i.e. the offset within the 3770-- lowest addressed storage unit containing part or all of the field. 3771-- Set to No_Uint if no first bit position is assigned yet. 3772 3773-- Normalized_Position (Uint14) 3774-- Defined in components and discriminants. Indicates the normalized 3775-- value of Position for the component, i.e. the offset in storage 3776-- units from the start of the record to the lowest addressed storage 3777-- unit containing part or all of the field. 3778 3779-- Normalized_Position_Max (Uint10) 3780-- Defined in components and discriminants. For almost all cases, this 3781-- is the same as Normalized_Position. The one exception is for the case 3782-- of a discriminated record containing one or more arrays whose length 3783-- depends on discriminants. In this case, the Normalized_Position_Max 3784-- field represents the maximum possible value of Normalized_Position 3785-- assuming min/max values for discriminant subscripts in all fields. 3786-- This is used by Layout in front end layout mode to properly compute 3787-- the maximum size of such records (needed for allocation purposes when 3788-- there are default discriminants, and also for the 'Size value). 3789 3790-- Number_Dimensions (synthesized) 3791-- Applies to array types and subtypes. Returns the number of dimensions 3792-- of the array type or subtype as a value of type Pos. 3793 3794-- Number_Entries (synthesized) 3795-- Applies to concurrent types. Returns the number of entries that are 3796-- declared within the task or protected definition for the type. 3797 3798-- Number_Formals (synthesized) 3799-- Applies to subprograms and subprogram types. Yields the number of 3800-- formals as a value of type Pos. 3801 3802-- Object_Size_Clause (synthesized) 3803-- Applies to entities for types and subtypes. If an object size clause 3804-- is present in the rep item chain for an entity then the attribute 3805-- definition clause node is returned. Otherwise Object_Size_Clause 3806-- returns Empty if no item is present. Usually this is only meaningful 3807-- if the flag Has_Object_Size_Clause is set. This is because when the 3808-- representation item chain is copied for a derived type, it can inherit 3809-- an object size clause that is not applicable to the entity. 3810 3811-- OK_To_Rename (Flag247) 3812-- Defined only in entities for variables. If this flag is set, it 3813-- means that if the entity is used as the initial value of an object 3814-- declaration, the object declaration can be safely converted into a 3815-- renaming to avoid an extra copy. This is set for variables which are 3816-- generated by the expander to hold the result of evaluating some 3817-- expression. Most notably, the local variables used to store the result 3818-- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It 3819-- is only worth setting this flag for composites, since for primitive 3820-- types, it is cheaper to do the copy. 3821 3822-- Optimize_Alignment_Space (Flag241) 3823-- Defined in type, subtype, variable, and constant entities. This 3824-- flag records that the type or object is to be laid out in a manner 3825-- consistent with Optimize_Alignment (Space) mode. The compiler and 3826-- binder ensure a consistent view of any given type or object. If pragma 3827-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3828-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3829 3830-- Optimize_Alignment_Time (Flag242) 3831-- Defined in type, subtype, variable, and constant entities. This 3832-- flag records that the type or object is to be laid out in a manner 3833-- consistent with Optimize_Alignment (Time) mode. The compiler and 3834-- binder ensure a consistent view of any given type or object. If pragma 3835-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3836-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3837 3838-- Original_Access_Type (Node28) 3839-- Defined in E_Access_Subprogram_Type entities. Set only if the access 3840-- type was generated by the expander as part of processing an access- 3841-- to-protected-subprogram type. Points to the access-to-protected- 3842-- subprogram type. 3843 3844-- Original_Array_Type (Node21) 3845-- Defined in modular types and array types and subtypes. Set only if 3846-- the Is_Packed_Array_Impl_Type flag is set, indicating that the type 3847-- is the implementation type for a packed array, and in this case it 3848-- points to the original array type for which this is the packed 3849-- array implementation type. 3850 3851-- Original_Protected_Subprogram (Node41) 3852-- Defined in functions and procedures. Set only on internally built 3853-- dispatching subprograms of protected types to reference their original 3854-- non-dispatching protected subprogram since their names differ. 3855 3856-- Original_Record_Component (Node22) 3857-- Defined in components, including discriminants. The usage depends 3858-- on whether the record is a base type and whether it is tagged. 3859-- 3860-- In base tagged types: 3861-- When the component is inherited in a record extension, it points 3862-- to the original component (the entity of the ancestor component 3863-- which is not itself inherited) otherwise it points to itself. The 3864-- backend uses this attribute to implement the automatic dereference 3865-- in the extension and to apply the transformation: 3866-- 3867-- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp 3868-- 3869-- In base untagged types: 3870-- Always points to itself except for non-girder discriminants, where 3871-- it points to the girder discriminant it renames. 3872-- 3873-- In subtypes (tagged and untagged): 3874-- Points to the component in the base type. 3875 3876-- Overlays_Constant (Flag243) 3877-- Defined in all entities. Set only for E_Constant or E_Variable for 3878-- which there is an address clause that causes the entity to overlay 3879-- a constant object. 3880 3881-- Overridden_Operation (Node26) 3882-- Defined in subprograms. For overriding operations, points to the 3883-- user-defined parent subprogram that is being overridden. Note: this 3884-- attribute uses the same field as Static_Initialization. The latter 3885-- is only defined for internal initialization procedures, for which 3886-- Overridden_Operation is irrelevant. Thus this attribute must not be 3887-- set for init_procs. 3888 3889-- Package_Instantiation (Node26) 3890-- Defined in packages and generic packages. When defined, this field 3891-- references an N_Generic_Instantiation node associated with an 3892-- instantiated package. In the case where the referenced node has 3893-- been rewritten to an N_Package_Specification, the instantiation 3894-- node is available from the Original_Node field of the package spec 3895-- node. This is currently not guaranteed to be set in all cases, but 3896-- when set, the field is used in Get_Unit_Instantiation_Node as 3897-- one of the means of obtaining the instantiation node. Eventually 3898-- it should be set in all cases, including package entities associated 3899-- with formal packages. ??? 3900 3901-- Packed_Array_Impl_Type (Node23) 3902-- Defined in array types and subtypes, except for the string literal 3903-- subtype case, if the corresponding type is packed and implemented 3904-- specially (either bit-packed or packed to eliminate holes in the 3905-- non-contiguous enumeration index types). References the type used to 3906-- represent the packed array, which is either a modular type for short 3907-- static arrays or an array of System.Unsigned in the bit-packed case, 3908-- or a regular array in the non-standard enumeration index case. Note 3909-- that in some situations (internal types and references to fields of 3910-- variant records), it is not always possible to construct this type in 3911-- advance of its use. If this field is empty, then the necessary type 3912-- is declared on the fly for each reference to the array. 3913 3914-- Parameter_Mode (synthesized) 3915-- Applies to formal parameter entities. This is a synonym for Ekind, 3916-- used when obtaining the formal kind of a formal parameter (the result 3917-- is one of E_[In/Out/In_Out]_Parameter). 3918 3919-- Parent_Subtype (Node19) [base type only] 3920-- Defined in E_Record_Type. Set only for derived tagged types, in which 3921-- case it points to the subtype of the parent type. This is the type 3922-- that is used as the Etype of the _parent field. 3923 3924-- Part_Of_Constituents (Elist10) 3925-- Present in abstract state and variable entities. Contains all 3926-- constituents that are subject to indicator Part_Of (both aspect and 3927-- option variants). 3928 3929-- Part_Of_References (Elist11) 3930-- Present in variable entities. Contains all references to the variable 3931-- when it is subject to pragma Part_Of. If the variable is a constituent 3932-- of a single protected/task type, the references are examined as they 3933-- must appear only within the type defintion and the corresponding body. 3934 3935-- Partial_DIC_Procedure (synthesized) 3936-- Defined in type entities. Set for a private type and its full view 3937-- when the type is subject to pragma Default_Initial_Condition (DIC), or 3938-- when the type inherits a DIC pragma from a parent type. Points to the 3939-- entity of a procedure that takes a single argument of the given type 3940-- and verifies the assertion expression of the DIC pragma at run time. 3941-- When present, the Partial_DIC_Procedure of a type only checks DICs 3942-- associated with the partial (private) view of the type, and is invoked 3943-- by the full DIC_Procedure (which may check additional DICs associated 3944-- with the full view). 3945 3946-- Note: the reason this is marked as a synthesized attribute is that the 3947-- way this is stored is as an element of the Subprograms_For_Type field. 3948 3949-- Partial_Invariant_Procedure (synthesized) 3950-- Defined in types and subtypes. Set for private types when one or more 3951-- [class-wide] type invariants apply to them. Points to the entity for a 3952-- procedure which checks the invariant. This invariant procedure takes a 3953-- single argument of the given type, and returns if the invariant holds, 3954-- or raises exception Assertion_Error with an appropriate message if it 3955-- does not hold. This attribute is defined but always Empty for private 3956-- subtypes. This attribute is also set for the corresponding full type. 3957-- 3958-- Note: the reason this is marked as a synthesized attribute is that the 3959-- way this is stored is as an element of the Subprograms_For_Type field. 3960 3961-- Partial_Refinement_Constituents (synthesized) 3962-- Defined in abstract state entities. Returns the constituents that 3963-- refine the state in the current scope, which are allowed in a global 3964-- refinement in this scope. These consist of those constituents that are 3965-- abstract states with no or only partial refinement visible, and those 3966-- that are not themselves abstract states. 3967 3968-- Partial_View_Has_Unknown_Discr (Flag280) 3969-- Present in all types. Set to Indicate that the partial view of a type 3970-- has unknown discriminants. A default initialization of an object of 3971-- the type does not require an invariant check (AI12-0133). 3972 3973-- Pending_Access_Types (Elist15) 3974-- Defined in all types. Set for incomplete, private, Taft-amendment 3975-- types, and their corresponding full views. This list contains all 3976-- access types, both named and anonymous, declared between the partial 3977-- and the full view. The list is used by the finalization machinery to 3978-- ensure that the finalization masters of all pending access types are 3979-- fully initialized when the full view is frozen. 3980 3981-- Postconditions_Proc (Node14) 3982-- Defined in functions, procedures, entries, and entry families. Refers 3983-- to the entity of the _Postconditions procedure used to check contract 3984-- assertions on exit from a subprogram. 3985 3986-- Predicate_Function (synthesized) 3987-- Defined in all types. Set for types for which (Has_Predicates is True) 3988-- and for which a predicate procedure has been built that tests that the 3989-- specified predicates are True. Contains the entity for the function 3990-- which takes a single argument of the given type, and returns True if 3991-- the predicate holds and False if it does not. 3992-- 3993-- Note: flag Has_Predicate does not imply that Predicate_Function is set 3994-- to a non-empty entity; this happens, for example, for itypes created 3995-- when instantiating generic units with private types with predicates. 3996-- However, if an explicit pragma Predicate or Predicate aspect is given 3997-- either for private or full type declaration then both Has_Predicates 3998-- and a non-empty Predicate_Function will be set on both the partial and 3999-- full views of the type. 4000-- 4001-- Note: the reason this is marked as a synthesized attribute is that the 4002-- way this is stored is as an element of the Subprograms_For_Type field. 4003 4004-- Predicate_Function_M (synthesized) 4005-- Defined in all types. Present only if Predicate_Function is present, 4006-- and only if the predicate function has Raise_Expression nodes. It 4007-- is the special version created for membership tests, where if one of 4008-- these raise expressions is executed, the result is to return False. 4009 4010-- Predicated_Parent (Node38) 4011-- Defined on itypes created by subtype indications, when the parent 4012-- subtype has predicates. The itype shares the Predicate_Function 4013-- of the predicated parent, but this function may not have been built 4014-- at the point the Itype is constructed, so this attribute allows its 4015-- retrieval at the point a predicate check needs to be generated. 4016-- The utility Predicate_Function takes this link into account. 4017 4018-- Predicates_Ignored (Flag288) 4019-- Defined on all types. Indicates whether the subtype declaration is in 4020-- a context where Assertion_Policy is Ignore, in which case no checks 4021-- (static or dynamic) must be generated for objects of the type. 4022 4023-- Prev_Entity (Node36) 4024-- Defined in all entities. The entities of a scope are chained, and this 4025-- field is used as a backward pointer for this entity list - effectivly 4026-- making the entity chain doubly-linked. 4027 4028-- Primitive_Operations (synthesized) 4029-- Defined in concurrent types, tagged record types and subtypes, tagged 4030-- private types and tagged incomplete types. For concurrent types whose 4031-- Corresponding_Record_Type (CRT) is available, returns the list of 4032-- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist. 4033-- For all the other types returns the Direct_Primitive_Operations. 4034 4035-- Prival (Node17) 4036-- Defined in private components of protected types. Refers to the entity 4037-- of the component renaming declaration generated inside protected 4038-- subprograms, entries or barrier functions. 4039 4040-- Prival_Link (Node20) 4041-- Defined in constants and variables which rename private components of 4042-- protected types. Set to the original private component. 4043 4044-- Private_Dependents (Elist18) 4045-- Defined in private (sub)types. Records the subtypes of the private 4046-- type, derivations from it, and records and arrays with components 4047-- dependent on the type. 4048-- 4049-- The subtypes are traversed when installing and deinstalling (the full 4050-- view of) a private type in order to ensure correct view of the 4051-- subtypes. 4052-- 4053-- Used in similar fashion for incomplete types: holds list of subtypes 4054-- of these incomplete types that have discriminant constraints. The 4055-- full views of these subtypes are constructed when the full view of 4056-- the incomplete type is processed. 4057 4058-- In addition, if the incomplete type is the designated type in an 4059-- access definition for an access parameter, the operation may be 4060-- a dispatching primitive operation, which is only known when the full 4061-- declaration of the type is seen. Subprograms that have such an 4062-- access parameter are also placed in the list of private_dependents. 4063 4064-- Protected_Body_Subprogram (Node11) 4065-- Defined in protected operations. References the entity for the 4066-- subprogram which implements the body of the operation. 4067 4068-- Protected_Formal (Node22) 4069-- Defined in formal parameters (in, in out and out parameters). Used 4070-- only for formals of protected operations. References corresponding 4071-- formal parameter in the unprotected version of the operation that 4072-- is created during expansion. 4073 4074-- Protected_Subprogram (Node39) 4075-- Defined in functions and procedures. Set for the pair of subprograms 4076-- which emulate the runtime semantics of a protected subprogram. Denotes 4077-- the entity of the origial protected subprogram. 4078 4079-- Protection_Object (Node23) 4080-- Applies to protected entries, entry families and subprograms. Denotes 4081-- the entity which is used to rename the _object component of protected 4082-- types. 4083 4084-- Reachable (Flag49) 4085-- Defined in labels. The flag is set over the range of statements in 4086-- which a goto to that label is legal. 4087 4088-- Receiving_Entry (Node19) 4089-- Defined in procedures. Set for an internally generated procedure which 4090-- wraps the original statements of an accept alternative. Designates the 4091-- entity of the task entry being accepted. 4092 4093-- Referenced (Flag156) 4094-- Defined in all entities. Set if the entity is referenced, except for 4095-- the case of an appearance of a simple variable that is not a renaming 4096-- as the left side of an assignment in which case Referenced_As_LHS is 4097-- set instead, or a similar appearance as an out parameter actual, in 4098-- which case Referenced_As_Out_Parameter is set. 4099 4100-- Referenced_As_LHS (Flag36): 4101-- Defined in all entities. This flag is set instead of Referenced if a 4102-- simple variable that is not a renaming appears as the left side of an 4103-- assignment. The reason we distinguish this kind of reference is that 4104-- we have a separate warning for variables that are only assigned and 4105-- never read. 4106 4107-- Referenced_As_Out_Parameter (Flag227): 4108-- Defined in all entities. This flag is set instead of Referenced if a 4109-- simple variable that is not a renaming appears as an actual for an out 4110-- formal. The reason we distinguish this kind of reference is that 4111-- we have a separate warning for variables that are only assigned and 4112-- never read, and out parameters are a special case. 4113 4114-- Refinement_Constituents (Elist8) 4115-- Present in abstract state entities. Contains all the constituents that 4116-- refine the state, in other words, all the hidden states that appear in 4117-- the constituent_list of aspect/pragma Refined_State. 4118 4119-- Register_Exception_Call (Node20) 4120-- Defined in exception entities. When an exception is declared, 4121-- a call is expanded to Register_Exception. This field points to 4122-- the expanded N_Procedure_Call_Statement node for this call. It 4123-- is used for Import/Export_Exception processing to modify the 4124-- register call to make appropriate entries in the special tables 4125-- used for handling these pragmas at run time. 4126 4127-- Related_Array_Object (Node25) 4128-- Defined in array types and subtypes. Used only for the base type 4129-- and subtype created for an anonymous array object. Set to point 4130-- to the entity of the corresponding array object. Currently used 4131-- only for type-related error messages. 4132 4133-- Related_Expression (Node24) 4134-- Defined in variables, types and functions. When Set for internally 4135-- generated entities, it may be used to denote the source expression 4136-- whose elaboration created the variable declaration. If set, it is used 4137-- for generating clearer messages from CodePeer. It is used on source 4138-- entities that are variables in iterator specifications, to provide 4139-- a link to the container that is the domain of iteration. This allows 4140-- for better cross-reference information when the loop modifies elements 4141-- of the container, and suppresses spurious warnings. 4142-- Finally this node is used on functions specified via the Real_Literal 4143-- aspect, to denote the 2-parameter overloading, if found. 4144-- 4145-- Shouldn't it also be used for the same purpose in errout? It seems 4146-- odd to have two mechanisms here??? 4147 4148-- Related_Instance (Node15) 4149-- Defined in the wrapper packages created for subprogram instances. 4150-- The internal subprogram that implements the instance is inside the 4151-- wrapper package, but for debugging purposes its external symbol 4152-- must correspond to the name and scope of the related instance. 4153 4154-- Related_Type (Node27) 4155-- Defined in components, constants and variables. Set when there is an 4156-- associated dispatch table to point to entities containing primary or 4157-- secondary tags. Not set in the _tag component of record types. 4158 4159-- Relative_Deadline_Variable (Node28) [implementation base type only] 4160-- Defined in task type entities. This flag is set if a valid and 4161-- effective pragma Relative_Deadline applies to the base type. Points 4162-- to the entity for a variable that is created to hold the value given 4163-- in a Relative_Deadline pragma for a task type. 4164 4165-- Renamed_Entity (Node18) 4166-- Defined in exception, generic unit, package, and subprogram entities. 4167-- Set when the entity is defined by a renaming declaration. Denotes the 4168-- renamed entity, or transitively the ultimate renamed entity if there 4169-- is a chain of renaming declarations. Empty if no renaming. 4170 4171-- Renamed_In_Spec (Flag231) 4172-- Defined in package entities. If a package renaming occurs within 4173-- a package spec, then this flag is set on the renamed package. The 4174-- purpose is to prevent a warning about unused entities in the renamed 4175-- package. Such a warning would be inappropriate since clients of the 4176-- package can see the entities in the package via the renaming. 4177 4178-- Renamed_Object (Node18) 4179-- Defined in components, constants, discriminants, formal parameters, 4180-- generic formals, loop parameters, and variables. Set to non-Empty if 4181-- the object was declared by a renaming declaration. For constants and 4182-- variables, the attribute references the tree node for the name of the 4183-- renamed object. For formal parameters, the field is used in inlining 4184-- and maps the entities of all formal parameters of a subprogram to the 4185-- entities of the corresponding actuals. For formals of a task entry, 4186-- the attribute denotes the local renaming that replaces the actual 4187-- within an accept statement. For all remaining cases (discriminants, 4188-- loop parameters) the field is Empty. 4189 4190-- Renaming_Map (Uint9) 4191-- Defined in generic subprograms, generic packages, and their 4192-- instances. Also defined in the instances of the corresponding 4193-- bodies. Denotes the renaming map (generic entities => instance 4194-- entities) used to construct the instance by giving an index into 4195-- the tables used to represent these maps. See Sem_Ch12 for further 4196-- details. The maps for package instances are also used when the 4197-- instance is the actual corresponding to a formal package. 4198 4199-- Requires_Overriding (Flag213) 4200-- Defined in all subprograms and entries. Set for subprograms that 4201-- require overriding as defined by RM-2005-3.9.3(6/2). Note that this 4202-- is True only for implicitly declared subprograms; it is not set on the 4203-- parent type's subprogram. See also Is_Abstract_Subprogram. 4204 4205-- Return_Applies_To (Node8) 4206-- Defined in E_Return_Statement. Points to the entity representing 4207-- the construct to which the return statement applies, as defined in 4208-- RM-6.5(4/2). Note that a (simple) return statement within an 4209-- extended_return_statement applies to the extended_return_statement, 4210-- even though it causes the whole function to return. 4211-- Also defined in special E_Block entities built as E_Return_Statement 4212-- for extended return statements and attached to the block statement 4213-- by Expand_N_Extended_Return_Statement before being turned into an 4214-- E_Block by semantic analysis. 4215 4216-- Return_Present (Flag54) 4217-- Defined in function and generic function entities. Set if the 4218-- function contains a return statement (used for error checking). 4219-- This flag can also be set in procedure and generic procedure 4220-- entities (for convenience in setting it), but is only tested 4221-- for the function case. 4222 4223-- Returns_By_Ref (Flag90) 4224-- Defined in subprogram type entities and functions. Set if a function 4225-- (or an access-to-function type) returns a result by reference, either 4226-- because its return type is a by-reference-type or because the function 4227-- explicitly uses the secondary stack. 4228 4229-- Reverse_Bit_Order (Flag164) [base type only] 4230-- Defined in all record type entities. Set if entity has a Bit_Order 4231-- aspect (set by an aspect clause or attribute definition clause) that 4232-- has reversed the order of bits from the default value. When this flag 4233-- is set, a component clause must specify a set of bits entirely within 4234-- a single storage unit (Ada 95) or within a single machine scalar (see 4235-- Ada 2005 AI-133), or must occupy an integral number of storage units. 4236 4237-- Reverse_Storage_Order (Flag93) [base type only] 4238-- Defined in all record and array type entities. Set if entity has a 4239-- Scalar_Storage_Order aspect (set by an aspect clause or attribute 4240-- definition clause) that has reversed the order of storage elements 4241-- from the default value. When this flag is set for a record type, 4242-- the Bit_Order aspect must be set to the same value (either explicitly 4243-- or as the target default value). 4244 4245-- Rewritten_For_C (Flag287) 4246-- Defined on functions that return a constrained array type, when 4247-- Modify_Tree_For_C is set. Indicates that a procedure with an extra 4248-- out parameter has been created for it, and calls must be rewritten as 4249-- calls to the new procedure. 4250 4251-- RM_Size (Uint13) 4252-- Defined in all type and subtype entities. Contains the value of 4253-- type'Size as defined in the RM. See also the Esize field and 4254-- and the description on "Handling of Type'Size Values". A value 4255-- of zero in this field for a non-discrete type means that 4256-- the front end has not yet determined the size value. For the 4257-- case of a discrete type, this field is always set by the front 4258-- end and zero is a legitimate value for a type with one value. 4259 4260-- Root_Type (synthesized) 4261-- Applies to all type entities. For class-wide types, returns the root 4262-- type of the class covered by the CW type, otherwise returns the 4263-- ultimate derivation ancestor of the given type. This function 4264-- preserves the view, i.e. the Root_Type of a partial view is the 4265-- partial view of the ultimate ancestor, the Root_Type of a full view 4266-- is the full view of the ultimate ancestor. Note that this function 4267-- does not correspond exactly to the use of root type in the RM, since 4268-- in the RM root type applies to a class of types, not to a type. 4269 4270-- Scalar_Range (Node20) 4271-- Defined in all scalar types (including modular types, where the 4272-- bounds are 0 .. modulus - 1). References a node in the tree that 4273-- contains the bounds for the range. Note that this information 4274-- could be obtained by rummaging around the tree, but it is more 4275-- convenient to have it immediately at hand in the entity. The 4276-- contents of Scalar_Range can either be an N_Subtype_Indication 4277-- node (with a constraint), a Range node, or an Integer_Type_Definition, 4278-- but not a simple subtype reference (a subtype is converted into a 4279-- explicit range). 4280 4281-- Scale_Value (Uint16) 4282-- Defined in decimal fixed-point types and subtypes. This holds the 4283-- value of the Scale attribute for the type, i.e. the scale of the type 4284-- defined as the integer N such that the delta is equal to 10.0**(-N). 4285-- Note that, if Scale_Value is positive, then it is equal to Aft_Value. 4286 4287-- Scope (Node3) 4288-- Defined in all entities. Points to the entity for the scope (block, 4289-- loop, subprogram, package etc.) in which the entity is declared. 4290-- Since this field is in the base part of the entity node, the access 4291-- routines for this field are in Sinfo. Note that for a child unit, 4292-- the Scope will be the parent package, and for a root library unit, 4293-- the Scope will be Standard. 4294 4295-- Scope_Depth (synthesized) 4296-- Applies to program units, blocks, loops, return statements, 4297-- concurrent types, private types and entries, and also to record types, 4298-- i.e. to any entity that can appear on the scope stack. Yields the 4299-- scope depth value, which for those entities other than records is 4300-- simply the scope depth value, for record entities, it is the 4301-- Scope_Depth of the record scope. 4302 4303-- Scope_Depth_Value (Uint22) 4304-- Defined in program units, blocks, loops, return statements, 4305-- concurrent types, private types and entries. 4306-- Indicates the number of scopes that statically enclose the declaration 4307-- of the unit or type. Library units have a depth of zero. Note that 4308-- record types can act as scopes but do NOT have this field set (see 4309-- Scope_Depth above). 4310 4311-- Scope_Depth_Set (synthesized) 4312-- Applies to a special predicate function that returns a Boolean value 4313-- indicating whether or not the Scope_Depth field has been set. It is 4314-- needed, since returns an invalid value in this case. 4315 4316-- Sec_Stack_Needed_For_Return (Flag167) 4317-- Defined in scope entities (blocks, entries, entry families, functions, 4318-- and procedures). Set to True when secondary stack is used to hold the 4319-- returned value of a function and thus should not be released on scope 4320-- exit. 4321 4322-- Shared_Var_Procs_Instance (Node22) 4323-- Defined in variables. Set non-Empty only if Is_Shared_Passive is 4324-- set, in which case this is the entity for the associated instance of 4325-- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details. 4326 4327-- Size_Check_Code (Node19) 4328-- Defined in constants and variables. Normally Empty. Set if code is 4329-- generated to check the size of the object. This field is used to 4330-- suppress this code if a subsequent address clause is encountered. 4331 4332-- Size_Clause (synthesized) 4333-- Applies to all entities. If a size clause is present in the rep 4334-- item chain for an entity then the attribute definition clause node 4335-- for the size clause is returned. Otherwise Size_Clause returns Empty 4336-- if no item is present. Usually this is only meaningful if the flag 4337-- Has_Size_Clause is set. This is because when the representation item 4338-- chain is copied for a derived type, it can inherit a size clause that 4339-- is not applicable to the entity. 4340 4341-- Size_Depends_On_Discriminant (Flag177) 4342-- Defined in all entities for types and subtypes. Indicates that the 4343-- size of the type depends on the value of one or more discriminants. 4344-- Currently, this flag is only set for arrays which have one or more 4345-- bounds depending on a discriminant value. 4346 4347-- Size_Known_At_Compile_Time (Flag92) 4348-- Defined in all entities for types and subtypes. Indicates that the 4349-- size of objects of the type is known at compile time. This flag is 4350-- used to optimize some generated code sequences, and also to enable 4351-- some error checks (e.g. disallowing component clauses on variable 4352-- length objects). It is set conservatively (i.e. if it is True, the 4353-- size is certainly known at compile time, if it is False, then the 4354-- size may or may not be known at compile time, but the code will 4355-- assume that it is not known). Note that the value may be known only 4356-- to the back end, so the fact that this flag is set does not mean that 4357-- the front end can access the value. 4358 4359-- Small_Value (Ureal21) 4360-- Defined in fixed point types. Points to the universal real for the 4361-- Small of the type, either as given in a representation clause, or 4362-- as computed (as a power of two) by the compiler. 4363 4364-- SPARK_Aux_Pragma (Node41) 4365-- Present in concurrent type, [generic] package spec and package body 4366-- entities. For concurrent types and package specs it refers to the 4367-- SPARK mode setting for the private part. This field points to the 4368-- N_Pragma node that either appears in the private part or is inherited 4369-- from the enclosing context. For package bodies, it refers to the SPARK 4370-- mode of the elaboration sequence after the BEGIN. The fields points to 4371-- the N_Pragma node that either appears in the statement sequence or is 4372-- inherited from the enclosing context. In all cases, if the pragma is 4373-- inherited, then the SPARK_Aux_Pragma_Inherited flag is set. 4374 4375-- SPARK_Aux_Pragma_Inherited (Flag266) 4376-- Present in concurrent type, [generic] package spec and package body 4377-- entities. Set if the SPARK_Aux_Pragma field points to a pragma that is 4378-- inherited, rather than a local one. 4379 4380-- SPARK_Pragma (Node40) 4381-- Present in the following entities: 4382-- 4383-- abstract states 4384-- constants 4385-- entries 4386-- operators 4387-- [generic] packages 4388-- package bodies 4389-- [generic] subprograms 4390-- subprogram bodies 4391-- variables 4392-- types 4393-- 4394-- Points to the N_Pragma node that applies to the initial declaration or 4395-- body. This is either set by a local SPARK_Mode pragma or is inherited 4396-- from the context (from an outer scope for the spec case or from the 4397-- spec for the body case). In the case where the attribute is inherited, 4398-- flag SPARK_Pragma_Inherited is set. Empty if no SPARK_Mode pragma is 4399-- applicable. 4400 4401-- SPARK_Pragma_Inherited (Flag265) 4402-- Present in the following entities: 4403-- 4404-- abstract states 4405-- constants 4406-- entries 4407-- operators 4408-- [generic] packages 4409-- package bodies 4410-- [generic] subprograms 4411-- subprogram bodies 4412-- variables 4413-- types 4414-- 4415-- Set if the SPARK_Pragma attribute points to an inherited pragma rather 4416-- than a local one. 4417 4418-- Spec_Entity (Node19) 4419-- Defined in package body entities. Points to corresponding package 4420-- spec entity. Also defined in subprogram body parameters in the 4421-- case where there is a separate spec, where this field references 4422-- the corresponding parameter entities in the spec. 4423 4424-- SSO_Set_High_By_Default (Flag273) [base type only] 4425-- Defined for record and array types. Set in the base type if a pragma 4426-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4427-- the record or array was declared and therefore applies to it. 4428 4429-- SSO_Set_Low_By_Default (Flag272) [base type only] 4430-- Defined for record and array types. Set in the base type if a pragma 4431-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4432-- the record or array was declared and therefore applies to it. 4433 4434-- Static_Discrete_Predicate (List25) 4435-- Defined in discrete types/subtypes with static predicates (with the 4436-- two flags Has_Predicates and Has_Static_Predicate set). Set if the 4437-- type/subtype has a static predicate. Points to a list of expression 4438-- and N_Range nodes that represent the predicate in canonical form. The 4439-- canonical form has entries sorted in ascending order, with duplicates 4440-- eliminated, and adjacent ranges coalesced, so that there is always a 4441-- gap in the values between successive entries. The entries in this list 4442-- are fully analyzed and typed with the base type of the subtype. Note 4443-- that all entries are static and have values within the subtype range. 4444 4445-- Static_Elaboration_Desired (Flag77) 4446-- Defined in library-level packages. Set by the pragma of the same 4447-- name, to indicate that static initialization must be attempted for 4448-- all types declared in the package, and that a warning must be emitted 4449-- for those types to which static initialization is not available. 4450 4451-- Static_Initialization (Node30) 4452-- Defined in initialization procedures for types whose objects can be 4453-- initialized statically. The value of this attribute is a positional 4454-- aggregate whose components are compile-time static values. Used 4455-- when available in object declarations to eliminate the call to the 4456-- initialization procedure, and to minimize elaboration code. Note: 4457-- This attribute uses the same field as Overridden_Operation, which is 4458-- irrelevant in init_procs. 4459 4460-- Static_Real_Or_String_Predicate (Node25) 4461-- Defined in real types/subtypes with static predicates (with the two 4462-- flags Has_Predicates and Has_Static_Predicate set). Set if the type 4463-- or subtype has a static predicate. Points to the return expression 4464-- of the predicate function. This is the original expression given as 4465-- the predicate except that occurrences of the type are replaced by 4466-- occurrences of the formal parameter of the predicate function (note 4467-- that the spec of this function including this formal parameter name 4468-- is available from the Subprograms_For_Type field; it can be accessed 4469-- as Predicate_Function (typ)). Also, in the case where a predicate is 4470-- inherited, the expression is of the form: 4471-- 4472-- xxxPredicate (typ2 (ent)) AND THEN expression 4473-- 4474-- where typ2 is the type from which the predicate is inherited, ent is 4475-- the entity for the current predicate function, and xxxPredicate is the 4476-- inherited predicate (from typ2). Finally for a predicate that inherits 4477-- from another predicate but does not add a predicate of its own, the 4478-- expression may consist of the above xxxPredicate call on its own. 4479 4480-- Status_Flag_Or_Transient_Decl (Node15) 4481-- Defined in constant, loop, and variable entities. Applies to objects 4482-- that require special treatment by the finalization machinery, such as 4483-- extended return results, IF and CASE expression results, and objects 4484-- inside N_Expression_With_Actions nodes. The attribute contains the 4485-- entity of a flag which specifies particular behavior over a region of 4486-- code or the declaration of a "hook" object. 4487-- In which case is it a flag, or a hook object??? 4488 4489-- Storage_Size_Variable (Node26) [implementation base type only] 4490-- Defined in access types and task type entities. This flag is set 4491-- if a valid and effective pragma Storage_Size applies to the base 4492-- type. Points to the entity for a variable that is created to 4493-- hold the value given in a Storage_Size pragma for an access 4494-- collection or a task type. Note that in the access type case, 4495-- this field is defined only in the root type (since derived types 4496-- share the same storage pool). 4497 4498-- Stored_Constraint (Elist23) 4499-- Defined in entities that can have discriminants (concurrent types 4500-- subtypes, record types and subtypes, private types and subtypes, 4501-- limited private types and subtypes and incomplete types). Points 4502-- to an element list containing the expressions for each of the 4503-- stored discriminants for the record (sub)type. 4504 4505-- Stores_Attribute_Old_Prefix (Flag270) 4506-- Defined in constants, variables, and types which are created during 4507-- expansion in order to save the value of attribute 'Old's prefix. 4508 4509-- Strict_Alignment (Flag145) [implementation base type only] 4510-- Defined in all type entities. Indicates that the type is by-reference 4511-- or contains an aliased part. This forbids packing a component of this 4512-- type tighter than the alignment and size of the type, as specified by 4513-- RM 13.2(7) modified by AI12-001 as a Binding Interpretation. 4514 4515-- String_Literal_Length (Uint16) 4516-- Defined in string literal subtypes (which are created to correspond 4517-- to string literals in the program). Contains the length of the string 4518-- literal. 4519 4520-- String_Literal_Low_Bound (Node18) 4521-- Defined in string literal subtypes (which are created to correspond 4522-- to string literals in the program). Contains an expression whose 4523-- value represents the low bound of the literal. This is a copy of 4524-- the low bound of the applicable index constraint if there is one, 4525-- or a copy of the low bound of the index base type if not. 4526 4527-- Subprograms_For_Type (Elist29) 4528-- Defined in all types. The list may contain the entities of the default 4529-- initial condition procedure, invariant procedure, and the two versions 4530-- of the predicate function. 4531-- 4532-- Historical note: This attribute used to be a direct linked list of 4533-- entities rather than an Elist. The Elist allows greater flexibility 4534-- in inheritance of subprograms between views of the same type. 4535 4536-- Subps_Index (Uint24) 4537-- Present in subprogram entries. Set if the subprogram contains nested 4538-- subprograms, or is a subprogram nested within such a subprogram. Holds 4539-- the index in the Exp_Unst.Subps table for the subprogram. Note that 4540-- for the outer level subprogram, this is the starting index in the Subp 4541-- table for the entries for this subprogram. 4542 4543-- Suppress_Elaboration_Warnings (Flag303) 4544-- NOTE: this flag is relevant only for the legacy ABE mechanism and 4545-- should not be used outside of that context. 4546-- 4547-- Defined in all entities, can be set only for subprogram entities and 4548-- for variables. If this flag is set then Sem_Elab will not generate 4549-- elaboration warnings for the subprogram or variable. Suppression of 4550-- such warnings is automatic for subprograms for which elaboration 4551-- checks are suppressed (without the need to set this flag), but the 4552-- flag is also set for various internal entities (such as init procs) 4553-- which are known not to generate any possible access before elaboration 4554-- and it is set on variables when a warning is given to avoid multiple 4555-- elaboration warnings for the same variable. 4556 4557-- Suppress_Initialization (Flag105) 4558-- Defined in all variable, type and subtype entities. If set for a base 4559-- type, then the generation of initialization procedures is suppressed 4560-- for the type. Any other implicit initialization (e.g. from the use of 4561-- pragma Initialize_Scalars) is also suppressed if this flag is set for 4562-- either the subtype in question, or for the base type. For variables, 4563-- this flag suppresses all implicit initialization for the object, even 4564-- if the type would normally require initialization. Set by use of 4565-- pragma Suppress_Initialization and also for internal entities where 4566-- we know that no initialization is required. For example, enumeration 4567-- image table entities set it. 4568 4569-- Suppress_Style_Checks (Flag165) 4570-- Defined in all entities. Suppresses any style checks specifically 4571-- associated with the given entity if set. 4572 4573-- Suppress_Value_Tracking_On_Call (Flag217) 4574-- Defined in all entities. Set in a scope entity if value tracking is to 4575-- be suppressed on any call within the scope. Used when an access to a 4576-- local subprogram is computed, to deal with the possibility that this 4577-- value may be passed around, and if used, may clobber a local variable. 4578 4579-- Task_Body_Procedure (Node25) 4580-- Defined in task types and subtypes. Points to the entity for the task 4581-- task body procedure (as further described in Exp_Ch9, task bodies are 4582-- expanded into procedures). A convenient function to retrieve this 4583-- field is Sem_Util.Get_Task_Body_Procedure. 4584-- 4585-- The last sentence is odd??? Why not have Task_Body_Procedure go to the 4586-- Underlying_Type of the Root_Type??? 4587 4588-- Thunk_Entity (Node31) 4589-- Defined in functions and procedures which have been classified as 4590-- Is_Thunk. Set to the target entity called by the thunk. 4591 4592-- Treat_As_Volatile (Flag41) 4593-- Defined in all type entities, and also in constants, components and 4594-- variables. Set if this entity is to be treated as volatile for code 4595-- generation purposes. Always set if Is_Volatile is set, but can also 4596-- be set as a result of situations (such as address overlays) where 4597-- the front end wishes to force volatile handling to inhibit aliasing 4598-- optimization which might be legally ok, but is undesirable. Note 4599-- that the backend always tests this flag rather than Is_Volatile. 4600-- The front end tests Is_Volatile if it is concerned with legality 4601-- checks associated with declared volatile variables, but if the test 4602-- is for the purposes of suppressing optimizations, then the front 4603-- end should test Treat_As_Volatile rather than Is_Volatile. 4604-- 4605-- Note: before testing Treat_As_Volatile, consider whether it would 4606-- be more appropriate to use Exp_Util.Is_Volatile_Reference instead, 4607-- which catches more cases of volatile references. 4608 4609-- Type_High_Bound (synthesized) 4610-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4611-- the high bound of a scalar type. The returned value is literal for a 4612-- base type, but may be an expression in the case of scalar type with 4613-- dynamic bounds. 4614 4615-- Type_Low_Bound (synthesized) 4616-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4617-- the low bound of a scalar type. The returned value is literal for a 4618-- base type, but may be an expression in the case of scalar type with 4619-- dynamic bounds. 4620 4621-- Underlying_Full_View (Node19) 4622-- Defined in private subtypes that are the completion of other private 4623-- types, or in private types that are derived from private subtypes. If 4624-- the full view of a private type T is derived from another private type 4625-- with discriminants Td, the full view of T is also private, and there 4626-- is no way to attach to it a further full view that would convey the 4627-- structure of T to the backend. The Underlying_Full_View is an 4628-- attribute of the full view that is a subtype of Td with the same 4629-- constraint as the declaration for T. The declaration for this subtype 4630-- is built at the point of the declaration of T, either as completion, 4631-- or as a subtype declaration where the base type is private and has a 4632-- private completion. If Td is already constrained, then its full view 4633-- can serve directly as the full view of T. 4634 4635-- Underlying_Record_View (Node28) 4636-- Defined in record types. Set for record types that are extensions of 4637-- types with unknown discriminants, and also set for internally built 4638-- underlying record views to reference its original record type. Record 4639-- types that are extensions of types with unknown discriminants do not 4640-- have a completion, but they cannot be used without having some 4641-- discriminated view at hand. This view is a record type with the same 4642-- structure, whose parent type is the full view of the parent in the 4643-- original type extension. 4644 4645-- Underlying_Type (synthesized) 4646-- Applies to all entities. This is the identity function except in the 4647-- case where it is applied to an incomplete or private type, in which 4648-- case it is the underlying type of the type declared by the completion, 4649-- or Empty if the completion has not yet been encountered and analyzed. 4650-- 4651-- Note: the reason this attribute applies to all entities, and not just 4652-- types, is to legitimize code where Underlying_Type is applied to an 4653-- entity which may or may not be a type, with the intent that if it is a 4654-- type, its underlying type is taken. 4655-- 4656-- Note also that the value of this attribute is interesting only after 4657-- the full view of the parent type has been processed. If the parent 4658-- type is declared in an enclosing package, the attribute will be non- 4659-- trivial only after the full view of the type has been analyzed. 4660 4661-- Universal_Aliasing (Flag216) [implementation base type only] 4662-- Defined in all type entities. Set to direct the back-end to avoid 4663-- any optimizations based on type-based alias analysis for this type. 4664-- Indicates that objects of this type can alias objects of any other 4665-- types, which guarantees that any objects can be referenced through 4666-- access types designating this type safely, whatever the actual type 4667-- of these objects. In other words, the effect is as though access 4668-- types designating this type were subject to No_Strict_Aliasing. 4669 4670-- Unset_Reference (Node16) 4671-- Defined in variables and out parameters. This is normally Empty. It 4672-- is set to point to an identifier that represents a reference to the 4673-- entity before any value has been set. Only the first such reference 4674-- is identified. This field is used to generate a warning message if 4675-- necessary (see Sem_Warn.Check_Unset_Reference). 4676 4677-- Used_As_Generic_Actual (Flag222) 4678-- Defined in all entities, set if the entity is used as an argument to 4679-- a generic instantiation. Used to tune certain warning messages, and 4680-- in checking type conformance within an instantiation that involves 4681-- incomplete formal and actual types. 4682 4683-- Uses_Lock_Free (Flag188) 4684-- Defined in protected type entities. Set to True when the Lock Free 4685-- implementation is used for the protected type. This implementation is 4686-- based on atomic transactions and doesn't require anymore the use of 4687-- Protection object (see System.Tasking.Protected_Objects). 4688 4689-- Uses_Sec_Stack (Flag95) 4690-- Defined in scope entities (blocks, entries, entry families, functions, 4691-- loops, and procedures). Set to True when the secondary stack is used 4692-- in this scope and must be released on exit unless flag 4693-- Sec_Stack_Needed_For_Return is set. 4694 4695-- Validated_Object (Node38) 4696-- Defined in variables. Contains the object whose value is captured by 4697-- the variable for validity check purposes. 4698 4699-- Warnings_Off (Flag96) 4700-- Defined in all entities. Set if a pragma Warnings (Off, entity-name) 4701-- is used to suppress warnings for a given entity. It is also used by 4702-- the compiler in some situations to kill spurious warnings. Note that 4703-- clients should generally not test this flag directly, but instead 4704-- use function Has_Warnings_Off. 4705 4706-- Warnings_Off_Used (Flag236) 4707-- Defined in all entities. Can only be set if Warnings_Off is set. If 4708-- set indicates that a warning was suppressed by the Warnings_Off flag, 4709-- and Unmodified/Unreferenced would not have suppressed the warning. 4710 4711-- Warnings_Off_Used_Unmodified (Flag237) 4712-- Defined in all entities. Can only be set if Warnings_Off is set and 4713-- Has_Pragma_Unmodified is not set. If set indicates that a warning was 4714-- suppressed by the Warnings_Off status but that pragma Unmodified 4715-- would also have suppressed the warning. 4716 4717-- Warnings_Off_Used_Unreferenced (Flag238) 4718-- Defined in all entities. Can only be set if Warnings_Off is set and 4719-- Has_Pragma_Unreferenced is not set. If set indicates that a warning 4720-- was suppressed by the Warnings_Off status but that pragma Unreferenced 4721-- would also have suppressed the warning. 4722 4723-- Was_Hidden (Flag196) 4724-- Defined in all entities. Used to save the value of the Is_Hidden 4725-- attribute when the limited-view is installed (Ada 2005: AI-217). 4726 4727-- Wrapped_Entity (Node27) 4728-- Defined in functions and procedures which have been classified as 4729-- Is_Primitive_Wrapper. Set to the entity being wrapper. 4730 4731--------------------------- 4732-- Renaming and Aliasing -- 4733--------------------------- 4734 4735-- Several entity attributes relate to renaming constructs, and to the use of 4736-- different names to refer to the same entity. The following is a summary of 4737-- these constructs and their prefered uses. 4738 4739-- There are three related attributes: 4740 4741-- Renamed_Entity 4742-- Renamed_Object 4743-- Alias 4744 4745-- They all overlap because they are supposed to apply to different entity 4746-- kinds. They are semantically related, and have the following intended uses: 4747 4748-- a) Renamed_Entity applies to entities in renaming declarations that rename 4749-- an entity, so the value of the attribute IS an entity. This applies to 4750-- generic renamings, package renamings, exception renamings, and subprograms 4751-- renamings that rename a subprogram (rather than an attribute, an entry, a 4752-- protected operation, etc). 4753 4754-- b) Alias applies to overloadable entities, and the value is an overloadable 4755-- entity. So this is a subset of the previous one. We use the term Alias to 4756-- cover both renamings and inherited operations, because both cases are 4757-- handled in the same way when expanding a call. Namely the Alias of a given 4758-- subprogram is the subprogram that will actually be called. 4759 4760-- Both a) and b) are set transitively, so that in fact it is not necessary to 4761-- traverse chains of renamings when looking for the original entity: it's 4762-- there in one step (this is done when analyzing renaming declarations other 4763-- than object renamings in sem_ch8). 4764 4765-- c) Renamed_Object applies to constants and variables. Given that the name 4766-- in an object renaming declaration is not necessarily an entity name, the 4767-- value of the attribute is the tree for that name, eg AR (1).Comp. The case 4768-- when that name is in fact an entity is not handled specially. This is why 4769-- in a few cases we need to use a loop to trace a chain of object renamings 4770-- where all of them happen to be entities. So: 4771 4772-- X : integer; 4773-- Y : integer renames X; -- renamed object is the identifier X 4774-- Z : integer renames Y; -- renamed object is the identifier Y 4775 4776-- The front-end does not store explicitly the fact that Z renames X. 4777 4778-------------------------------------- 4779-- Delayed Freezing and Elaboration -- 4780-------------------------------------- 4781 4782-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 4783-- freeze node, which appears later in the expanded tree. 4784 4785-- a) The flag is used by the front-end to trigger expansion actions 4786-- which include the generation of that freeze node. Typically this happens at 4787-- the end of the current compilation unit, or before the first subprogram 4788-- body is encountered in the current unit. See files freeze and exp_ch13 for 4789-- details on the actions triggered by a freeze node, which include the 4790-- construction of initialization procedures and dispatch tables. 4791 4792-- b) The flag is used by the backend to defer elaboration of the entity until 4793-- its freeze node is seen. In the absence of an explicit freeze node, an 4794-- entity is frozen (and elaborated) at the point of declaration. 4795 4796-- For object declarations, the flag is set when an address clause for the 4797-- object is encountered. Legality checks on the address expression only 4798-- take place at the freeze point of the object. 4799 4800-- Most types have an explicit freeze node, because they cannot be elaborated 4801-- until all representation and operational items that apply to them have been 4802-- analyzed. Private types and incomplete types have the flag set as well, as 4803-- do task and protected types. 4804 4805-- Implicit base types created for type derivations, as well as classwide 4806-- types created for all tagged types, have the flag set. 4807 4808-- If a subprogram has an access parameter whose designated type is incomplete 4809-- the subprogram has the flag set. 4810 4811------------------ 4812-- Access Kinds -- 4813------------------ 4814 4815-- The following entity kinds are introduced by the corresponding type 4816-- definitions: 4817 4818-- E_Access_Type, 4819-- E_General_Access_Type, 4820-- E_Access_Subprogram_Type, 4821-- E_Anonymous_Access_Subprogram_Type, 4822-- E_Access_Protected_Subprogram_Type, 4823-- E_Anonymous_Access_Protected_Subprogram_Type 4824-- E_Anonymous_Access_Type. 4825 4826-- E_Access_Subtype is for an access subtype created by a subtype 4827-- declaration. 4828 4829-- In addition, we define the kind E_Allocator_Type to label allocators. 4830-- This is because special resolution rules apply to this construct. 4831-- Eventually the constructs are labeled with the access type imposed by 4832-- the context. The backend should never see types with this Ekind. 4833 4834-- Similarly, the type E_Access_Attribute_Type is used as the initial kind 4835-- associated with an access attribute. After resolution a specific access 4836-- type will be established as determined by the context. 4837 4838-- Finally, the type Any_Access is used to label -null- during type 4839-- resolution. Any_Access is also replaced by the context type after 4840-- resolution. 4841 4842-------------------------------- 4843-- Classification of Entities -- 4844-------------------------------- 4845 4846-- The classification of program entities which follows is a refinement of 4847-- the list given in RM 3.1(1). E.g., separate entities denote subtypes of 4848-- different type classes. Ada 95 entities include class wide types, 4849-- protected types, subprogram types, generalized access types, generic 4850-- formal derived types and generic formal packages. 4851 4852-- The order chosen for these kinds allows us to classify related entities 4853-- so that they are contiguous.

Meanwhile, the access 6889 -- procedures in the body of Einfo permit many, but not all, attributes 6890 -- to be applied to an E_Void entity, precisely so that this kind of 6891 -- pre-setting of attributes works. This is really a hole in the dynamic 6892 -- type checking, since there is no assurance that the eventual Ekind 6893 -- value will be appropriate for the attributes set, and the consequence 6894 -- is that the dynamic type checking in the Einfo body is unnecessarily 6895 -- weak.

Of course, from the point of view of a user of this 6928 -- package, the distinction is not visible (even the field information 6929 -- provided below should be disregarded, as it is subject to change 6930 -- without notice). A number of attributes appear as lists: lists of 6931 -- formals, lists of actuals, of discriminants, etc. For these, pairs 6932 -- of functions are defined, which take the form: 6933 6934 -- function First_Thing (E : Enclosing_Construct) return Thing; 6935 -- function Next_Thing (T : Thing) return Thing; 6936 6937 -- The end of iteration is always signaled by a value of Empty, so that 6938 -- loops over these chains invariably have the form: 6939 6940 -- This : Thing; 6941 -- ... 6942 -- This := First_Thing (E); 6943 6944 -- while Present (This) loop 6945 -- Do_Something_With (This); 6946 -- ... 6947 -- This := Next_Thing (This); 6948 -- end loop; 6949 6950 ----------------------------------- 6951 -- Handling of Check Suppression -- 6952 ----------------------------------- 6953 6954 -- There are three ways that checks can be suppressed: 6955 6956 -- 1. At the command line level 6957 -- 2. At the scope level. 6958 -- 3. At the entity level. 6959 6960 -- See spec of Sem in sem.ads for details of the data structures used 6961 -- to keep track of these various methods for suppressing checks. 6962 6963 ------------------------------- 6964 -- Handling of Discriminants -- 6965 ------------------------------- 6966 6967 -- During semantic processing, discriminants are separate entities which 6968 -- reflect the semantic properties and allowed usage of discriminants in 6969 -- the language. 6970 6971 -- In the case of discriminants used as bounds, the references are handled 6972 -- directly, since special processing is needed in any case. However, there 6973 -- are two circumstances in which discriminants are referenced in a quite 6974 -- general manner, like any other variables: 6975 6976 -- In initialization expressions for records. Note that the expressions 6977 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline 6978 -- pragmas are effectively in this category, since these pragmas are 6979 -- converted to initialized record fields in the Corresponding_Record_ 6980 -- Type. 6981 6982 -- In task and protected bodies, where the discriminant values may be 6983 -- referenced freely within these bodies. Discriminants can also appear 6984 -- in bounds of entry families and in defaults of operations. 6985 6986 -- In both these cases, the discriminants must be treated essentially as 6987 -- objects. The following approach is used to simplify and minimize the 6988 -- special processing that is required. 6989 6990 -- When a record type with discriminants is analyzed, semantic processing 6991 -- creates the entities for the discriminants. It also creates additional 6992 -- sets of entities called discriminals, one for each of the discriminants, 6993 -- and the Discriminal field of the discriminant entity points to this 6994 -- additional entity, which is initially created as an uninitialized 6995 -- (E_Void) entity. 6996 6997 -- During expansion of expressions, any discriminant reference is replaced 6998 -- by a reference to the corresponding discriminal. When the initialization 6999 -- procedure for the record is created (there will always be one, since 7000 -- discriminants are present, see Exp_Ch3 for further details), the 7001 -- discriminals are used as the entities for the formal parameters of 7002 -- this initialization procedure. The references to these discriminants 7003 -- have already been replaced by references to these discriminals, which 7004 -- are now the formal parameters corresponding to the required objects. 7005 7006 -- In the case of a task or protected body, the semantics similarly creates 7007 -- a set of discriminals for the discriminants of the task or protected 7008 -- type. When the procedure is created for the task body, the parameter 7009 -- passed in is a reference to the task value type, which contains the 7010 -- required discriminant values. The expander creates a set of declarations 7011 -- of the form: 7012 7013 -- discr_nameD : constant discr_type renames _task.discr_name; 7014 7015 -- where discr_nameD is the discriminal entity referenced by the task 7016 -- discriminant, and _task is the task value passed in as the parameter. 7017 -- Again, any references to discriminants in the task body have been 7018 -- replaced by the discriminal reference, which is now an object that 7019 -- contains the required value. 7020 7021 -- This approach for tasks means that two sets of discriminals are needed 7022 -- for a task type, one for the initialization procedure, and one for the 7023 -- task body. This works out nicely, since the semantics allocates one set 7024 -- for the task itself, and one set for the corresponding record. 7025 7026 -- The one bit of trickiness arises in making sure that the right set of 7027 -- discriminals is used at the right time. First the task definition is 7028 -- processed. Any references to discriminants here are replaced by the 7029 -- corresponding *task* discriminals (the record type doesn't even exist 7030 -- yet, since it is constructed as part of the expansion of the task 7031 -- declaration, which happens after the semantic processing of the task 7032 -- definition). The discriminants to be used for the corresponding record 7033 -- are created at the same time as the other discriminals, and held in the 7034 -- CR_Discriminant field of the discriminant. A use of the discriminant in 7035 -- a bound for an entry family is replaced with the CR_Discriminant because 7036 -- it controls the bound of the entry queue array which is a component of 7037 -- the corresponding record. 7038 7039 -- Just before the record initialization routine is constructed, the 7040 -- expander exchanges the task and record discriminals. This has two 7041 -- effects. First the generation of the record initialization routine 7042 -- uses the discriminals that are now on the record, which is the set 7043 -- that used to be on the task, which is what we want. 7044 7045 -- Second, a new set of (so far unused) discriminals is now on the task 7046 -- discriminants, and it is this set that will be used for expanding the 7047 -- task body, and also for the discriminal declarations at the start of 7048 -- the task body. 7049 7050 --------------------------------------------------- 7051 -- Handling of private data in protected objects -- 7052 --------------------------------------------------- 7053 7054 -- Private components in protected types pose problems similar to those 7055 -- of discriminants. Private data is visible and can be directly referenced 7056 -- from protected bodies. However, when protected entries and subprograms 7057 -- are expanded into corresponding bodies and barrier functions, private 7058 -- components lose their original context and visibility. 7059 7060 -- To remedy this side effect of expansion, private components are expanded 7061 -- into renamings called "privals", by analogy with "discriminals". 7062 7063 -- private_comp : comp_type renames _object.private_comp; 7064 7065 -- Prival declarations are inserted during the analysis of subprogram and 7066 -- entry bodies to ensure proper visibility for any subsequent expansion. 7067 -- _Object is the formal parameter of the generated corresponding body or 7068 -- a local renaming which denotes the protected object obtained from entry 7069 -- parameter _O. Privals receive minimal decoration upon creation and are 7070 -- categorized as either E_Variable for the general case or E_Constant when 7071 -- they appear in functions. 7072 7073 -- Along with the local declarations, each private component carries a 7074 -- placeholder which references the prival entity in the current body. This 7075 -- form of indirection is used to resolve name clashes of privals and other 7076 -- locally visible entities such as parameters, local objects, entry family 7077 -- indexes or identifiers used in the barrier condition. 7078 7079 -- When analyzing the statements of a protected subprogram or entry, any 7080 -- reference to a private component must resolve to the locally declared 7081 -- prival through normal visibility. In case of name conflicts (the cases 7082 -- above), the prival is marked as hidden and acts as a weakly declared 7083 -- entity. As a result, the reference points to the correct entity. When a 7084 -- private component is denoted by an expanded name (prot_type.comp for 7085 -- example), the expansion mechanism uses the placeholder of the component 7086 -- to correct the Entity and Etype of the reference. 7087 7088 ------------------- 7089 -- Type Synonyms -- 7090 ------------------- 7091 7092 -- The following type synonyms are used to tidy up the function and 7093 -- procedure declarations that follow, and also to make it possible to meet 7094 -- the requirement for the XEINFO utility that all function specs must fit 7095 -- on a single source line. 7096 7097 subtype B is Boolean; 7098 subtype C is Component_Alignment_Kind; 7099 subtype E is Entity_Id; 7100 subtype F is Float_Rep_Kind; 7101 subtype M is Mechanism_Type; 7102 subtype N is Node_Id; 7103 subtype U is Uint; 7104 subtype R is Ureal; 7105 subtype L is Elist_Id; 7106 subtype S is List_Id; 7107 7108 -------------------------------- 7109 -- Attribute Access Functions -- 7110 -------------------------------- 7111 7112 -- All attributes are manipulated through a procedural interface.
