Other 48-- attributes include sets of meanings for overloaded names, possible 49-- types for overloaded expressions, flags to indicate deferred constants, 50-- incomplete types, etc. These attributes are stored in available fields in 51-- tree nodes (i.e. fields not used by the parser, as defined by the Sinfo 52-- package specification), and accessed by means of a set of subprograms 53-- which define an abstract interface. 54 55-- There are two kinds of semantic information 56 57-- First, the tree nodes with the following Nkind values: 58 59-- N_Defining_Identifier 60-- N_Defining_Character_Literal 61-- N_Defining_Operator_Symbol 62 63-- are called Entities, and constitute the information that would often 64-- be stored separately in a symbol table. These nodes are all extended 65-- to provide extra space, and contain fields which depend on the entity 66-- kind, as defined by the contents of the Ekind field. The use of the 67-- Ekind field, and the associated fields in the entity, are defined 68-- in this package, as are the access functions to these fields. 69 70-- Second, in some cases semantic information is stored directly in other 71-- kinds of nodes, e.g. the Etype field, used to indicate the type of an 72-- expression. The access functions to these fields are defined in the 73-- Sinfo package, but their full documentation is to be found in 74-- the Einfo package specification. 75 76-- Declaration processing places information in the nodes of their defining 77-- identifiers. Name resolution places in all other occurrences of an 78-- identifier a pointer to the corresponding defining occurrence. 79 80-------------------------------- 81-- The XEINFO Utility Program -- 82-------------------------------- 83 84-- XEINFO is a utility program which automatically produces a C header file, 85-- einfo.h from the spec and body of package Einfo. It reads the input files 86-- einfo.ads and einfo.adb and produces the output file einfo.h. XEINFO is run 87-- automatically by the build scripts when you do a full bootstrap. 88 89-- In order for this utility program to operate correctly, the form of the 90-- einfo.ads and einfo.adb files must meet certain requirements and be laid 91-- out in a specific manner. 92 93-- The general form of einfo.ads is as follows: 94 95-- type declaration for type Entity_Kind 96-- subtype declarations declaring subranges of Entity_Kind 97-- subtype declarations declaring synonyms for some standard types 98-- function specs for attributes 99-- procedure specs 100-- pragma Inline declarations 101 102-- This order must be observed. There are no restrictions on the procedures, 103-- since the C header file only includes functions (The back end is not 104-- allowed to modify the generated tree). However, functions are required to 105-- have headers that fit on a single line. 106 107-- XEINFO reads and processes the function specs and the pragma Inlines. For 108-- functions that are declared as inlined, XEINFO reads the corresponding body 109-- from einfo.adb, and processes it into C code. This results in some strict 110-- restrictions on which functions can be inlined: 111 112-- The function spec must be on a single line 113 114-- There can only be a single statement, contained on a single line, 115-- not counting any pragma Assert statements. 116 117-- This single statement must either be a function call with simple, 118-- single token arguments, or it must be a membership test of the form 119-- a in b, where a and b are single tokens. 120 121-- For functions that are not inlined, there is no restriction on the body, 122-- and XEINFO generates a direct reference in the C header file which allows 123-- the C code in the backend to directly call the corresponding Ada body. 124 125---------------------------------- 126-- Handling of Type'Size Values -- 127---------------------------------- 128 129-- The Ada 95 RM contains some rather peculiar (to us) rules on the value 130-- of type'Size (see RM 13.3(55)). We have found that attempting to use 131-- these RM Size values generally, and in particular for determining the 132-- default size of objects, creates chaos, and major incompatibilities in 133-- existing code. 134 135-- We proceed as follows, for discrete and fixed-point subtypes, we have 136-- two separate sizes for each subtype: 137 138-- The Object_Size, which is used for determining the default size of 139-- objects and components. This size value can be referred to using the 140-- Object_Size attribute. The phrase "is used" here means that it is 141-- the basis of the determination of the size. The backend is free to 142-- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone 143-- character might be stored in 32 bits on a machine with no efficient 144-- byte access instructions such as the Alpha. 145 146-- The default rules for the value of Object_Size for fixed-point and 147-- discrete types are as follows: 148 149-- The Object_Size for base subtypes reflect the natural hardware 150-- size in bits (see Ttypes and Cstand for integer types). For 151-- enumeration and fixed-point base subtypes have 8, 16, 32, or 64 152-- bits for this size, depending on the range of values to be stored. 153 154-- The Object_Size of a subtype is the same as the Object_Size of 155-- the subtype from which it is obtained. 156 157-- The Object_Size of a derived base type is copied from the parent 158-- base type, and the Object_Size of a derived first subtype is copied 159-- from the parent first subtype. 160 161-- The Value_Size which is the number of bits required to store a value 162-- of the type. This size can be referred to using the Value_Size 163-- attribute. This value is used to determine how tightly to pack 164-- records or arrays with components of this type, and also affects 165-- the semantics of unchecked conversion (unchecked conversions where 166-- the Value_Size values differ generate a warning, and are potentially 167-- target dependent). 168 169-- The default rule for the value of Value_Size are as follows: 170 171-- The Value_Size for a base subtype is the minimum number of bits 172-- required to store all values of the type (including the sign bit 173-- only if negative values are possible). 174 175-- If a subtype statically matches the first subtype, then it has 176-- by default the same Value_Size as the first subtype. This is a 177-- consequence of RM 13.1(14) ("if two subtypes statically match, 178-- then their subtype-specific aspects are the same".) 179 180-- All other subtypes have a Value_Size corresponding to the minimum 181-- number of bits required to store all values of the subtype. For 182-- dynamic bounds, it is assumed that the value can range down or up 183-- to the corresponding bound of the ancestor 184 185-- The RM defined attribute Size corresponds to the Value_Size attribute 186 187-- The Size attribute may be defined for a first-named subtype. This sets 188-- the Value_Size of the first-named subtype to the given value, and the 189-- Object_Size of this first-named subtype to the given value padded up 190-- to an appropriate boundary. It is a consequence of the default rules 191-- above that this Object_Size will apply to all further subtypes. On the 192-- other hand, Value_Size is affected only for the first subtype, any 193-- dynamic subtypes obtained from it directly, and any statically matching 194-- subtypes. The Value_Size of any other static subtypes is not affected. 195 196-- Value_Size and Object_Size may be explicitly set for any subtype using 197-- an attribute definition clause. Note that the use of these attributes 198-- can cause the RM 13.1(14) rule to be violated. If two access types 199-- reference aliased objects whose subtypes have differing Object_Size 200-- values as a result of explicit attribute definition clauses, then it 201-- is erroneous to convert from one access subtype to the other. 202 203-- At the implementation level, Esize stores the Object_Size and the 204-- RM_Size field stores the Value_Size (and hence the value of the 205-- Size attribute, which, as noted above, is equivalent to Value_Size). 206 207-- To get a feel for the difference, consider the following examples (note 208-- that in each case the base is short_short_integer with a size of 8): 209 210-- Object_Size Value_Size 211 212-- type x1 is range 0..5; 8 3 213 214-- type x2 is range 0..5; 215-- for x2'size use 12; 16 12 216 217-- subtype x3 is x2 range 0 .. 3; 16 2 218 219-- subtype x4 is x2'base range 0 .. 10; 8 4 220 221-- subtype x5 is x2 range 0 .. dynamic; 16 (7) 222 223-- subtype x6 is x2'base range 0 .. dynamic; 8 (7) 224 225-- Note: the entries marked (7) are not actually specified by the Ada 95 RM, 226-- but it seems in the spirit of the RM rules to allocate the minimum number 227-- of bits known to be large enough to hold the given range of values. 228 229-- So far, so good, but GNAT has to obey the RM rules, so the question is 230-- under what conditions must the RM Size be used. The following is a list 231-- of the occasions on which the RM Size must be used: 232 233-- Component size for packed arrays or records 234-- Value of the attribute Size for a type 235-- Warning about sizes not matching for unchecked conversion 236 237-- The RM_Size field keeps track of the RM Size as needed in these 238-- three situations. 239 240-- For elementary types other than discrete and fixed-point types, the 241-- Object_Size and Value_Size are the same (and equivalent to the RM 242-- attribute Size). Only Size may be specified for such types. 243 244-- For composite types, Object_Size and Value_Size are computed from their 245-- respective value for the type of each element as well as the layout. 246 247-- All size attributes are stored as Uint values. Negative values are used to 248-- reference GCC expressions for the case of non-static sizes, as explained 249-- in Repinfo. 250 251-------------------------------------- 252-- Delayed Freezing and Elaboration -- 253-------------------------------------- 254 255-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 256-- freeze node, which appears later in the expanded tree. 257 258-- a) The flag is used by the front-end to trigger expansion actions which 259-- include the generation of that freeze node. Typically this happens at the 260-- end of the current compilation unit, or before the first subprogram body is 261-- encountered in the current unit. See files freeze and exp_ch13 for details 262-- on the actions triggered by a freeze node, which include the construction 263-- of initialization procedures and dispatch tables. 264 265-- b) The presence of a freeze node on an entity is used by the backend to 266-- defer elaboration of the entity until its freeze node is seen. In the 267-- absence of an explicit freeze node, an entity is frozen (and elaborated) 268-- at the point of declaration. 269 270-- For object declarations, the flag is set when an address clause for the 271-- object is encountered. Legality checks on the address expression only take 272-- place at the freeze point of the object. 273 274-- Most types have an explicit freeze node, because they cannot be elaborated 275-- until all representation and operational items that apply to them have been 276-- analyzed. Private types and incomplete types have the flag set as well, as 277-- do task and protected types. 278 279-- Implicit base types created for type derivations, as well as classwide 280-- types created for all tagged types, have the flag set. 281 282-- If a subprogram has an access parameter whose designated type is incomplete 283-- the subprogram has the flag set. 284 285----------------------- 286-- Entity Attributes -- 287----------------------- 288 289-- This section contains a complete list of the attributes that are defined 290-- on entities. Some attributes apply to all entities, others only to certain 291-- kinds of entities. In the latter case the attribute should only be set or 292-- accessed if the Ekind field indicates an appropriate entity. 293 294-- There are two kinds of attributes that apply to entities, stored and 295-- synthesized. Stored attributes correspond to a field or flag in the entity 296-- itself. Such attributes are identified in the table below by giving the 297-- field or flag in the attribute that is used to hold the attribute value. 298-- Synthesized attributes are not stored directly, but are rather computed as 299-- needed from other attributes, or from information in the tree. These are 300-- marked "synthesized" in the table below. The stored attributes have both 301-- access functions and set procedures to set the corresponding values, while 302-- synthesized attributes have only access functions. 303 304-- Note: in the case of Node, Uint, or Elist fields, there are cases where the 305-- same physical field is used for different purposes in different entities, 306-- so these access functions should only be referenced for the class of 307-- entities in which they are defined as being present. Flags are not 308-- overlapped in this way, but nevertheless as a matter of style and 309-- abstraction (which may or may not be checked by assertions in the 310-- body), this restriction should be observed for flag fields as well. 311 312-- Note: certain of the attributes on types apply only to base types, and 313-- are so noted by the notation [base type only]. These are cases where the 314-- attribute of any subtype is the same as the attribute of the base type. 315-- The attribute can be referenced on a subtype (and automatically retrieves 316-- the value from the base type). However, it is an error to try to set the 317-- attribute on other than the base type, and if assertions are enabled, 318-- an attempt to set the attribute on a subtype will raise an assert error. 319 320-- Other attributes are noted as applying to the [implementation base type 321-- only]. These are representation attributes which must always apply to a 322-- full non-private type, and where the attributes are always on the full 323-- type. The attribute can be referenced on a subtype (and automatically 324-- retries the value from the implementation base type). However, it is an 325-- error to try to set the attribute on other than the implementation base 326-- type, and if assertions are enabled, an attempt to set the attribute on a 327-- subtype will raise an assert error. 328 329-- Abstract_States (Elist25) 330-- Defined for E_Package entities. Contains a list of all the abstract 331-- states declared by the related package. 332 333-- Accept_Address (Elist21) 334-- Defined in entries. If an accept has a statement sequence, then an 335-- address variable is created, which is used to hold the address of the 336-- parameters, as passed by the runtime. Accept_Address holds an element 337-- list which represents a stack of entities for these address variables. 338-- The current entry is the top of the stack, which is the last element 339-- on the list. A stack is required to handle the case of nested select 340-- statements referencing the same entry. 341 342-- Access_Disp_Table (Elist16) [implementation base type only] 343-- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged 344-- types to point to their dispatch tables. The first two entities are 345-- associated with the primary dispatch table: 1) primary dispatch table 346-- with user-defined primitives 2) primary dispatch table with predefined 347-- primitives. For each interface type covered by the tagged type we also 348-- have: 3) secondary dispatch table with thunks of primitives covering 349-- user-defined interface primitives, 4) secondary dispatch table with 350-- thunks of predefined primitives, 5) secondary dispatch table with user 351-- defined primitives, and 6) secondary dispatch table with predefined 352-- primitives. The last entity of this list is an access type declaration 353-- used to expand dispatching calls through the primary dispatch table. 354-- For an untagged record, contains No_Elist. 355 356-- Activation_Record_Component (Node31) 357-- Defined in E_Variable, E_Constant, E_Loop_Parameter, E_In_Parameter, 358-- E_Out_Parameter, E_In_Out_Parameter nodes. Used only if we are in 359-- Opt.Unnest_Subprogram_Mode, in which case for the case of an uplevel 360-- referenced entity, this field contains the entity for the component 361-- in the generated ARECnT activation record (Exp_Unst for details). 362 363-- Actual_Subtype (Node17) 364-- Defined in variables, constants, and formal parameters. This is the 365-- subtype imposed by the value of the object, as opposed to its nominal 366-- subtype, which is imposed by the declaration. The actual subtype 367-- differs from the nominal one when the latter is indefinite (as in the 368-- case of an unconstrained formal parameter, or a variable declared 369-- with an unconstrained type and an initial value). The nominal subtype 370-- is the Etype entry for the entity. The Actual_Subtype field is set 371-- only if the actual subtype differs from the nominal subtype. If the 372-- actual and nominal subtypes are the same, then the Actual_Subtype 373-- field is Empty, and Etype indicates both types. 374-- 375-- For objects, the Actual_Subtype is set only if this is a discriminated 376-- type. For arrays, the bounds of the expression are obtained and the 377-- Etype of the object is directly the constrained subtype. This is 378-- rather irregular, and the semantic checks that depend on the nominal 379-- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv). 380 381-- Address_Clause (synthesized) 382-- Applies to entries, objects and subprograms. Set if an address clause 383-- is present which references the object or subprogram and points to 384-- the N_Attribute_Definition_Clause node. Empty if no Address clause. 385-- The expression in the address clause is always a constant that is 386-- defined before the entity to which the address clause applies. 387-- Note: The backend references this field in E_Task_Type entities??? 388 389-- Address_Taken (Flag104) 390-- Defined in all entities. Set if the Address or Unrestricted_Access 391-- attribute is applied directly to the entity, i.e. the entity is the 392-- entity of the prefix of the attribute reference. Also set if the 393-- entity is the second argument of an Asm_Input or Asm_Output attribute, 394-- as the construct may entail taking its address. Used by the backend to 395-- make sure that the address can be meaningfully taken, and also in the 396-- case of subprograms to control output of certain warnings. 397 398-- Aft_Value (synthesized) 399-- Applies to fixed and decimal types. Computes a universal integer that 400-- holds value of the Aft attribute for the type. 401 402-- Alias (Node18) 403-- Defined in overloadable entities (literals, subprograms, entries) and 404-- subprograms that cover a primitive operation of an abstract interface 405-- (that is, subprograms with the Interface_Alias attribute). In case of 406-- overloaded entities it points to the parent subprogram of a derived 407-- subprogram. In case of abstract interface subprograms it points to the 408-- subprogram that covers the abstract interface primitive. Also used for 409-- a subprogram renaming, where it points to the renamed subprogram. For 410-- an inherited operation (of a type extension) that is overridden in a 411-- private part, the Alias is the overriding operation. In this fashion a 412-- call from outside the package ends up executing the new body even if 413-- non-dispatching, and a call from inside calls the overriding operation 414-- because it hides the implicit one. Alias is always empty for entries. 415 416-- Alignment (Uint14) 417-- Defined in entities for types and also in constants, variables 418-- (including exceptions where it refers to the static data allocated for 419-- an exception), loop parameters, and formal parameters. This indicates 420-- the desired alignment for a type, or the actual alignment for an 421-- object. A value of zero (Uint_0) indicates that the alignment has not 422-- been set yet. The alignment can be set by an explicit alignment 423-- clause, or set by the front-end in package Layout, or set by the 424-- back-end as part of the back-end back-annotation process. The 425-- alignment field is also defined in E_Exception entities, but there it 426-- is used only by the back-end for back annotation. 427 428-- Alignment_Clause (synthesized) 429-- Applies to all entities for types and objects. If an alignment 430-- attribute definition clause is present for the entity, then this 431-- function returns the N_Attribute_Definition clause that specifies the 432-- alignment. If no alignment clause applies to the type, then the call 433-- to this function returns Empty. Note that the call can return a 434-- non-Empty value even if Has_Alignment_Clause is not set (happens with 435-- subtype and derived type declarations). Note also that a record 436-- definition clause with an (obsolescent) mod clause is converted 437-- into an attribute definition clause for this purpose. 438 439-- Associated_Formal_Package (Node12) 440-- Defined in packages that are the actuals of formal_packages. Points 441-- to the entity in the declaration for the formal package. 442 443-- Associated_Node_For_Itype (Node8) 444-- Defined in all type and subtype entities. Set non-Empty only for 445-- Itypes. Set to point to the associated node for the Itype, i.e. 446-- the node whose elaboration generated the Itype. This is used for 447-- copying trees, to determine whether or not to copy an Itype, and 448-- also for accessibility checks on anonymous access types. This 449-- node is typically an object declaration, component declaration, 450-- type or subtype declaration. For an access discriminant in a type 451-- declaration, the associated_node_for_itype is the discriminant 452-- specification. For an access parameter it is the enclosing subprogram 453-- declaration. 454-- 455-- Itypes have no explicit declaration, and therefore are not attached to 456-- the tree: their Parent field is always empty. The Associated_Node_For_ 457-- Itype is the only way to determine the construct that leads to the 458-- creation of a given itype entity. 459 460-- Associated_Storage_Pool (Node22) [root type only] 461-- Defined in simple and general access type entities. References the 462-- storage pool to be used for the corresponding collection. A value of 463-- Empty means that the default pool is to be used. This is defined 464-- only in the root type, since derived types must have the same pool 465-- as the parent type. 466 467-- Barrier_Function (Node12) 468-- Defined in protected entries and entry families. This is the 469-- subprogram declaration for the body of the function that returns 470-- the value of the entry barrier. 471 472-- Base_Type (synthesized) 473-- Applies to all type and subtype entities. Returns the base type of a 474-- type or subtype. The base type of a type is the type itself. The base 475-- type of a subtype is the type that it constrains (which is always 476-- a type entity, not some other subtype). Note that in the case of a 477-- subtype of a private type, it is possible for the base type attribute 478-- to return a private type, even if the subtype to which it applies is 479-- non-private. See also Implementation_Base_Type. Note: it is allowed to 480-- apply Base_Type to other than a type, in which case it simply returns 481-- the entity unchanged. 482 483-- Block_Node (Node11) 484-- Defined in block entities. Points to the identifier in the 485-- Block_Statement itself. Used when retrieving the block construct 486-- for finalization purposes, The block entity has an implicit label 487-- declaration in the enclosing declarative part, and has otherwise 488-- no direct connection in the tree with the block statement. The 489-- link is to the identifier (which is an occurrence of the entity) 490-- and not to the block_statement itself, because the statement may 491-- be rewritten, e.g. in the process of removing dead code. 492 493-- Body_Entity (Node19) 494-- Defined in package and generic package entities, points to the 495-- corresponding package body entity if one is present. 496 497-- Body_Needed_For_SAL (Flag40) 498-- Defined in package and subprogram entities that are compilation 499-- units. Indicates that the source for the body must be included 500-- when the unit is part of a standalone library. 501 502-- Body_References (Elist16) 503-- Defined in abstract state entities. Contains an element list of 504-- references (identifiers) that appear in a package body whose spec 505-- defines the related state. If the body refines the said state, all 506-- references on this list are illegal due to the visible refinement. 507 508-- BIP_Initialization_Call (Node29) 509-- Defined in constants and variables whose corresponding declaration 510-- is wrapped in a transient block and the inital value is provided by 511-- a build-in-place function call. Contains the relocated build-in-place 512-- call after the expansion has decoupled the call from the object. This 513-- attribute is used by the finalization machinery to insert cleanup code 514-- for all additional transient variables found in the transient block. 515 516-- C_Pass_By_Copy (Flag125) [implementation base type only] 517-- Defined in record types. Set if a pragma Convention for the record 518-- type specifies convention C_Pass_By_Copy. This convention name is 519-- treated as identical in all respects to convention C, except that 520-- if it is specified for a record type, then the C_Pass_By_Copy flag 521-- is set, and if a foreign convention subprogram has a formal of the 522-- corresponding type, then the parameter passing mechanism will be 523-- set to By_Copy (unless specifically overridden by an Import or 524-- Export pragma). 525 526-- Can_Never_Be_Null (Flag38) 527-- This flag is defined in all entities. It is set in an object which can 528-- never have a null value. Set for constant access values initialized to 529-- a non-null value. This is also set for all access parameters in Ada 83 530-- and Ada 95 modes, and for access parameters that explicitly exclude 531-- exclude null in Ada 2005 mode. 532-- 533-- This is used to avoid unnecessary resetting of the Is_Known_Non_Null 534-- flag for such entities. In Ada 2005 mode, this is also used when 535-- determining subtype conformance of subprogram profiles to ensure 536-- that two formals have the same null-exclusion status. 537-- 538-- This is also set on some access types, e.g. the Etype of the anonymous 539-- access type of a controlling formal. 540 541-- Can_Use_Internal_Rep (Flag229) [base type only] 542-- Defined in Access_Subprogram_Kind nodes. This flag is set by the 543-- front end and used by the backend. False means that the backend 544-- must represent the type in the same way as Convention-C types (and 545-- other foreign-convention types). On many targets, this means that 546-- the backend will use dynamically generated trampolines for nested 547-- subprograms. True means that the backend can represent the type in 548-- some internal way. On the aforementioned targets, this means that the 549-- backend will not use dynamically generated trampolines. This flag 550-- must be False if Has_Foreign_Convention is True; otherwise, the front 551-- end is free to set the policy. 552-- 553-- Setting this False in all cases corresponds to the traditional back 554-- end strategy, where all access-to-subprogram types are represented the 555-- same way, independent of the Convention. For further details, see also 556-- Always_Compatible_Rep in Targparm. 557-- 558-- Efficiency note: On targets that use dynamically generated 559-- trampolines, False generally favors efficiency of top-level 560-- subprograms, whereas True generally favors efficiency of nested 561-- ones. On other targets, this flag has little or no effect on 562-- efficiency. The front end should take this into account. In 563-- particular, pragma Favor_Top_Level gives a hint that the flag 564-- should be False. 565-- 566-- Note: We considered using Convention-C for this purpose, but we need 567-- this separate flag, because Convention-C implies that in the case of 568-- P'[Unrestricted_]Access, P also have convention C. Sometimes we want 569-- to have Can_Use_Internal_Rep False for an access type, but allow P to 570-- have convention Ada. 571 572-- Chars (Name1) 573-- Defined in all entities. This field contains an entry into the names 574-- table that has the character string of the identifier, character 575-- literal or operator symbol. See Namet for further details. Note that 576-- throughout the processing of the front end, this name is the simple 577-- unqualified name. However, just before the backend is called, a call 578-- is made to Qualify_All_Entity_Names. This causes entity names to be 579-- qualified using the encoding described in exp_dbug.ads, and from that 580-- point (including post backend steps, e.g. cross-reference generation), 581-- the entities will contain the encoded qualified names. 582 583-- Checks_May_Be_Suppressed (Flag31) 584-- Defined in all entities. Set if a pragma Suppress or Unsuppress 585-- mentions the entity specifically in the second argument. If this 586-- flag is set the Global_Entity_Suppress and Local_Entity_Suppress 587-- tables must be consulted to determine if there actually is an active 588-- Suppress or Unsuppress pragma that applies to the entity. 589 590-- Class_Wide_Type (Node9) 591-- Defined in all type entities. For a tagged type or subtype, returns 592-- the corresponding implicitly declared class-wide type. For a 593-- class-wide type, returns itself. Set to Empty for untagged types. 594 595-- Cloned_Subtype (Node16) 596-- Defined in E_Record_Subtype and E_Class_Wide_Subtype entities. 597-- Each such entity can either have a Discriminant_Constraint, in 598-- which case it represents a distinct type from the base type (and 599-- will have a list of components and discrimants in the list headed by 600-- First_Entity) or else no such constraint, in which case it will be a 601-- copy of the base type. 602-- 603-- o Each element of the list in First_Entity is copied from the base 604-- type; in that case, this field is Empty. 605-- 606-- o The list in First_Entity is shared with the base type; in that 607-- case, this field points to that entity. 608-- 609-- A record or classwide subtype may also be a copy of some other 610-- subtype and share the entities in the First_Entity with that subtype. 611-- In that case, this field points to that subtype. 612-- 613-- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides 614-- this field. Note that this field ONLY appears in subtype entries, not 615-- in type entries, it is not defined, and it is an error to reference 616-- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity. 617 618-- Comes_From_Source 619-- This flag appears on all nodes, including entities, and indicates 620-- that the node was created by the scanner or parser from the original 621-- source. Thus for entities, it indicates that the entity is defined 622-- in the original source program. 623 624-- Component_Alignment (special field) [base type only] 625-- Defined in array and record entities. Contains a value of type 626-- Component_Alignment_Kind indicating the alignment of components. 627-- Set to Calign_Default normally, but can be overridden by use of 628-- the Component_Alignment pragma. Note: this field is currently 629-- stored in a non-standard way, see body for details. 630 631-- Component_Bit_Offset (Uint11) 632-- Defined in record components (E_Component, E_Discriminant) if a 633-- component clause applies to the component. First bit position of 634-- given component, computed from the first bit and position values 635-- given in the component clause. A value of No_Uint means that the 636-- value is not yet known. The value can be set by the appearance of 637-- an explicit component clause in a record representation clause, 638-- or it can be set by the front-end in package Layout, or it can be 639-- set by the backend. By the time backend processing is completed, 640-- this field is always set. A negative value is used to represent 641-- a value which is not known at compile time, and must be computed 642-- at run-time (this happens if fields of a record have variable 643-- lengths). See package Layout for details of these values. 644-- 645-- Note: Component_Bit_Offset is redundant with respect to the fields 646-- Normalized_First_Bit and Normalized_Position, and could in principle 647-- be eliminated, but it is convenient in several situations, including 648-- use in the backend, to have this redundant field. 649 650-- Component_Clause (Node13) 651-- Defined in record components and discriminants. If a record 652-- representation clause is present for the corresponding record type a 653-- that specifies a position for the component, then the Component_Clause 654-- field of the E_Component entity points to the N_Component_Clause node. 655-- Set to Empty if no record representation clause was present, or if 656-- there was no specification for this component. 657 658-- Component_Size (Uint22) [implementation base type only] 659-- Defined in array types. It contains the component size value for 660-- the array. A value of No_Uint means that the value is not yet set. 661-- The value can be set by the use of a component size clause, or 662-- by the front end in package Layout, or by the backend. A negative 663-- value is used to represent a value which is not known at compile 664-- time, and must be computed at run-time (this happens if the type 665-- of the component has a variable length size). See package Layout 666-- for details of these values. 667 668-- Component_Type (Node20) [implementation base type only] 669-- Defined in array types and string types. References component type. 670 671-- Contains_Ignored_Ghost_Code (Flag279) 672-- Defined in blocks, packages and their bodies, subprograms and their 673-- bodies. Set if the entity contains any ignored Ghost code in the form 674-- of declaration, procedure call, assignment statement or pragma. 675 676-- Corresponding_Concurrent_Type (Node18) 677-- Defined in record types that are constructed by the expander to 678-- represent task and protected types (Is_Concurrent_Record_Type flag 679-- set). Points to the entity for the corresponding task type or the 680-- protected type. 681 682-- Corresponding_Discriminant (Node19) 683-- Defined in discriminants of a derived type, when the discriminant is 684-- used to constrain a discriminant of the parent type. Points to the 685-- corresponding discriminant in the parent type. Otherwise it is Empty. 686 687-- Corresponding_Equality (Node30) 688-- Defined in function entities for implicit inequality operators. 689-- Denotes the explicit or derived equality operation that creates 690-- the implicit inequality. Note that this field is not present in 691-- other function entities, only in implicit inequality routines, 692-- where Comes_From_Source is always False. 693 694-- Corresponding_Protected_Entry (Node18) 695-- Defined in subprogram bodies. Set for subprogram bodies that implement 696-- a protected type entry to point to the entity for the entry. 697 698-- Corresponding_Record_Type (Node18) 699-- Defined in protected and task types and subtypes. References the 700-- entity for the corresponding record type constructed by the expander 701-- (see Exp_Ch9). This type is used to represent values of the task type. 702 703-- Corresponding_Remote_Type (Node22) 704-- Defined in record types that describe the fat pointer structure for 705-- Remote_Access_To_Subprogram types. References the original access 706-- to subprogram type. 707 708-- CR_Discriminant (Node23) 709-- Defined in discriminants of concurrent types. Denotes the homologous 710-- discriminant of the corresponding record type. The CR_Discriminant is 711-- created at the same time as the discriminal, and used to replace 712-- occurrences of the discriminant within the type declaration. 713 714-- Current_Use_Clause (Node27) 715-- Defined in packages and in types. For packages, denotes the use 716-- package clause currently in scope that makes the package use_visible. 717-- For types, it denotes the use_type clause that makes the operators of 718-- the type visible. Used for more precise warning messages on redundant 719-- use clauses. 720 721-- Current_Value (Node9) 722-- Defined in all object entities. Set in E_Variable, E_Constant, formal 723-- parameters and E_Loop_Parameter entities if we have trackable current 724-- values. Set non-Empty if the (constant) current value of the variable 725-- is known, This value is valid only for references from the same 726-- sequential scope as the entity. The sequential scope of an entity 727-- includes the immediate scope and any contained scopes that are package 728-- specs, package bodies, blocks (at any nesting level) or statement 729-- sequences in IF or loop statements. 730-- 731-- Another related use of this field is to record information about the 732-- value obtained from an IF or WHILE statement condition. If the IF or 733-- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ", 734-- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a 735-- Current_Value field, RELOP is one of the six relational operators, and 736-- VAL is a compile-time known value then the Current_Value field of OBJ 737-- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node 738-- of the relevant construct, and the Condition field of this can be 739-- consulted to give information about the value of OBJ. For more details 740-- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition. 741 742-- Debug_Info_Off (Flag166) 743-- Defined in all entities. Set if a pragma Suppress_Debug_Info applies 744-- to the entity, or if internal processing in the compiler determines 745-- that suppression of debug information is desirable. Note that this 746-- flag is only for use by the front end as part of the processing for 747-- determining if Needs_Debug_Info should be set. The backend should 748-- always test Needs_Debug_Info, it should never test Debug_Info_Off. 749 750-- Debug_Renaming_Link (Node25) 751-- Used to link the variable associated with a debug renaming declaration 752-- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for 753-- details of the use of this field. 754 755-- Declaration_Node (synthesized) 756-- Applies to all entities. Returns the tree node for the construct that 757-- declared the entity. Normally this is just the Parent of the entity. 758-- One exception arises with child units, where the parent of the entity 759-- is a selected component/defining program unit name. Another exception 760-- is that if the entity is an incomplete type that has been completed or 761-- a private type, then we obtain the declaration node denoted by the 762-- full type, i.e. the full type declaration node. Also note that for 763-- subprograms, this returns the {function,procedure}_specification, not 764-- the subprogram_declaration. 765 766-- Default_Aspect_Component_Value (Node19) [base type only] 767-- Defined in array types. Holds the static value specified in a 768-- Default_Component_Value aspect specification for the array type. 769 770-- Default_Aspect_Value (Node19) [base type only] 771-- Defined in scalar types. Holds the static value specified in a 772-- Default_Value aspect specification for the type. 773 774-- Default_Expr_Function (Node21) 775-- Defined in parameters. It holds the entity of the parameterless 776-- function that is built to evaluate the default expression if it is 777-- more complex than a simple identifier or literal. For the latter 778-- simple cases or if there is no default value, this field is Empty. 779 780-- Default_Expressions_Processed (Flag108) 781-- A flag in subprograms (functions, operators, procedures) and in 782-- entries and entry families used to indicate that default expressions 783-- have been processed and to avoid multiple calls to process the 784-- default expressions (see Freeze.Process_Default_Expressions), which 785-- would not only waste time, but also generate false error messages. 786 787-- Default_Init_Cond_Procedure (synthesized) 788-- Defined in all types. Set for private [sub]types subject to pragma 789-- Default_Initial_Condition, their corresponding full views and derived 790-- types with at least one parent subject to the pragma. Contains the 791-- entity of the procedure which takes a single argument of the given 792-- type and verifies the assumption of the pragma. 793-- 794-- Note: the reason this is marked as a synthesized attribute is that the 795-- way this is stored is as an element of the Subprograms_For_Type field. 796 797-- Default_Value (Node20) 798-- Defined in formal parameters. Points to the node representing the 799-- expression for the default value for the parameter. Empty if the 800-- parameter has no default value (which is always the case for OUT 801-- and IN OUT parameters in the absence of errors). 802 803-- Delay_Cleanups (Flag114) 804-- Defined in entities that have finalization lists (subprograms 805-- blocks, and tasks). Set if there are pending generic body 806-- instantiations for the corresponding entity. If this flag is 807-- set, then generation of cleanup actions for the corresponding 808-- entity must be delayed, since the insertion of the generic body 809-- may affect cleanup generation (see Inline for further details). 810 811-- Delay_Subprogram_Descriptors (Flag50) 812-- Defined in entities for which exception subprogram descriptors 813-- are generated (subprograms, package declarations and package 814-- bodies). Defined if there are pending generic body instantiations 815-- for the corresponding entity. If this flag is set, then generation 816-- of the subprogram descriptor for the corresponding enities must 817-- be delayed, since the insertion of the generic body may add entries 818-- to the list of handlers. 819-- 820-- Note: for subprograms, Delay_Subprogram_Descriptors is set if and 821-- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a 822-- a block (in which case Delay_Subprogram_Descriptors is set for the 823-- containing subprogram). In addition Delay_Subprogram_Descriptors is 824-- set for a library level package declaration or body which contains 825-- delayed instantiations (in this case the descriptor refers to the 826-- enclosing elaboration procedure). 827 828-- Delta_Value (Ureal18) 829-- Defined in fixed and decimal types. Points to a universal real 830-- that holds value of delta for the type, as given in the declaration 831-- or as inherited by a subtype or derived type. 832 833-- Dependent_Instances (Elist8) 834-- Defined in packages that are instances. Holds list of instances 835-- of inner generics. Used to place freeze nodes for those instances 836-- after that of the current one, i.e. after the corresponding generic 837-- bodies. 838 839-- Depends_On_Private (Flag14) 840-- Defined in all type entities. Set if the type is private or if it 841-- depends on a private type. 842 843-- Derived_Type_Link (Node31) 844-- Defined in all type and subtype entries. Set in a base type if 845-- a derived type declaration is encountered which derives from 846-- this base type or one of its subtypes, and there are already 847-- primitive operations declared. In this case, it references the 848-- entity for the type declared by the derived type declaration. 849-- For example: 850-- 851-- type R is ... 852-- subtype RS is R ... 853-- ... 854-- type G is new RS ... 855-- 856-- In this case, if primitive operations have been declared for R, at 857-- the point of declaration of G, then the Derived_Type_Link of R is set 858-- to point to the entity for G. This is used to generate warnings for 859-- rep clauses that appear later on for R, which might result in an 860-- unexpected implicit conversion operation. 861-- 862-- Note: if there is more than one such derived type, the link will point 863-- to the last one (this is only used in generating warning messages). 864 865-- Designated_Type (synthesized) 866-- Applies to access types. Returns the designated type. Differs from 867-- Directly_Designated_Type in that if the access type refers to an 868-- incomplete type, and the full type is available, then this full type 869-- is returned instead of the incomplete type. 870 871-- Digits_Value (Uint17) 872-- Defined in floating point types and subtypes and decimal types and 873-- subtypes. Contains the Digits value specified in the declaration. 874 875-- Direct_Primitive_Operations (Elist10) 876-- Defined in tagged types and subtypes (including synchronized types), 877-- in tagged private types and in tagged incomplete types. Element list 878-- of entities for primitive operations of the tagged type. Not defined 879-- in untagged types. In order to follow the C++ ABI, entities of 880-- primitives that come from source must be stored in this list in the 881-- order of their occurrence in the sources. For incomplete types the 882-- list is always empty. 883 884-- Directly_Designated_Type (Node20) 885-- Defined in access types. This field points to the type that is 886-- directly designated by the access type. In the case of an access 887-- type to an incomplete type, this field references the incomplete 888-- type. Directly_Designated_Type is typically used in implementing the 889-- static semantics of the language; in implementing dynamic semantics, 890-- we typically want the full view of the designated type. The function 891-- Designated_Type obtains this full type in the case of access to an 892-- incomplete type. 893 894-- Discard_Names (Flag88) 895-- Defined in types and exception entities. Set if pragma Discard_Names 896-- applies to the entity. It is also set for declarative regions and 897-- package specs for which a Discard_Names pragma with zero arguments 898-- has been encountered. The purpose of setting this flag is to be able 899-- to set the Discard_Names attribute on enumeration types declared 900-- after the pragma within the same declarative region. This flag is 901-- set to False if a Keep_Names pragma appears for an enumeration type. 902 903-- Discriminal (Node17) 904-- Defined in discriminants (Discriminant formal: GNAT's first 905-- coinage). The entity used as a formal parameter that corresponds 906-- to a discriminant. See section "Handling of Discriminants" for 907-- full details of the use of discriminals. 908 909-- Discriminal_Link (Node10) 910-- Defined in E_In_Parameter or E_Constant entities. For discriminals, 911-- points back to corresponding discriminant. For other entities, must 912-- remain Empty. 913 914-- Discriminant_Checking_Func (Node20) 915-- Defined in components. Points to the defining identifier of the 916-- function built by the expander returns a Boolean indicating whether 917-- the given record component exists for the current discriminant 918-- values. 919 920-- Discriminant_Constraint (Elist21) 921-- Defined in entities whose Has_Discriminants flag is set (concurrent 922-- types, subtypes, record types and subtypes, private types and 923-- subtypes, limited private types and subtypes and incomplete types). 924-- It is an error to reference the Discriminant_Constraint field if 925-- Has_Discriminants is False. 926-- 927-- If the Is_Constrained flag is set, Discriminant_Constraint points 928-- to an element list containing the discriminant constraints in the 929-- same order in which the discriminants are declared. 930-- 931-- If the Is_Constrained flag is not set but the discriminants of the 932-- unconstrained type have default initial values then this field 933-- points to an element list giving these default initial values in 934-- the same order in which the discriminants are declared. Note that 935-- in this case the entity cannot be a tagged record type, because 936-- discriminants in this case cannot have defaults. 937-- 938-- If the entity is a tagged record implicit type, then this field is 939-- inherited from the first subtype (so that the itype is subtype 940-- conformant with its first subtype, which is needed when the first 941-- subtype overrides primitive operations inherited by the implicit 942-- base type). 943-- 944-- In all other cases Discriminant_Constraint contains the empty 945-- Elist (ie it is initialized with a call to New_Elmt_List). 946 947-- Discriminant_Default_Value (Node20) 948-- Defined in discriminants. Points to the node representing the 949-- expression for the default value of the discriminant. Set to 950-- Empty if the discriminant has no default value. 951 952-- Discriminant_Number (Uint15) 953-- Defined in discriminants. Gives the ranking of a discriminant in 954-- the list of discriminants of the type, i.e. a sequential integer 955-- index starting at 1 and ranging up to number of discriminants. 956 957-- Dispatch_Table_Wrappers (Elist26) [implementation base type only] 958-- Defined in E_Record_Type and E_Record_Subtype entities. Set in library 959-- level tagged type entities if we are generating statically allocated 960-- dispatch tables. Points to the list of dispatch table wrappers 961-- associated with the tagged type. For an untagged record, contains 962-- No_Elist. 963 964-- DTC_Entity (Node16) 965-- Defined in function and procedure entities. Set to Empty unless 966-- the subprogram is dispatching in which case it references the 967-- Dispatch Table pointer Component. For regular Ada tagged this, this 968-- is the _Tag component. For CPP_Class types and their descendants, 969-- this points to the component entity in the record that holds the 970-- Vtable pointer for the Vtable containing the entry referencing the 971-- subprogram. 972 973-- DT_Entry_Count (Uint15) 974-- Defined in E_Component entities. Only used for component marked 975-- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table) 976 977-- DT_Offset_To_Top_Func (Node25) 978-- Defined in E_Component entities. Only used for component marked 979-- Is_Tag. If present it stores the Offset_To_Top function used to 980-- provide this value in tagged types whose ancestor has discriminants. 981 982-- DT_Position (Uint15) 983-- Defined in function and procedure entities which are dispatching 984-- (should not be referenced without first checking that flag 985-- Is_Dispatching_Operation is True). Contains the offset into 986-- the Vtable for the entry that references the subprogram. 987 988-- Ekind (Ekind) 989-- Defined in all entities. Contains a value of the enumeration type 990-- Entity_Kind declared in a subsequent section in this spec. 991 992-- Elaborate_Body_Desirable (Flag210) 993-- Defined in package entities. Set if the elaboration circuitry detects 994-- a case where there is a package body that modifies one or more visible 995-- entities in the package spec and there is no explicit Elaborate_Body 996-- pragma for the package. This information is passed on to the binder, 997-- which attempts, but does not promise, to elaborate the body as close 998-- to the spec as possible. 999 1000-- Elaboration_Entity (Node13) 1001-- Defined in generic and non-generic package and subprogram entities. 1002-- This is a counter associated with the unit that is initially set to 1003-- zero, is incremented when an elaboration request for the unit is 1004-- made, and is decremented when a finalization request for the unit 1005-- is made. This is used for three purposes. First, it is used to 1006-- implement access before elaboration checks (the counter must be 1007-- non-zero to call a subprogram at elaboration time). Second, it is 1008-- used to guard against repeated execution of the elaboration code. 1009-- Third, it is used to ensure that the finalization code is executed 1010-- only after all clients have requested it. 1011-- 1012-- Note that we always allocate this counter, and set this field, but 1013-- we do not always actually use it. It is only used if it is needed 1014-- for access before elaboration use (see Elaboration_Entity_Required 1015-- flag) or if either the spec or the body has elaboration code. If 1016-- neither of these two conditions holds, then the entity is still 1017-- allocated (since we don't know early enough whether or not there 1018-- is elaboration code), but is simply not used for any purpose. 1019 1020-- Elaboration_Entity_Required (Flag174) 1021-- Defined in generic and non-generic package and subprogram entities. 1022-- Set only if Elaboration_Entity is non-Empty to indicate that the 1023-- counter is required to be non-zero even if there is no other 1024-- elaboration code. This occurs when the Elaboration_Entity counter 1025-- is used for access before elaboration checks. If the counter is 1026-- only used to prevent multiple execution of the elaboration code, 1027-- then if there is no other elaboration code, obviously there is no 1028-- need to set the flag. 1029 1030-- Encapsulating_State (Node10) 1031-- Defined in abstract states and variables. Contains the entity of an 1032-- ancestor state whose refinement utilizes this item as a constituent. 1033 1034-- Enclosing_Scope (Node18) 1035-- Defined in labels. Denotes the innermost enclosing construct that 1036-- contains the label. Identical to the scope of the label, except for 1037-- labels declared in the body of an accept statement, in which case the 1038-- entry_name is the Enclosing_Scope. Used to validate goto's within 1039-- accept statements. 1040 1041-- Entry_Accepted (Flag152) 1042-- Defined in E_Entry and E_Entry_Family entities. Set if there is 1043-- at least one accept for this entry in the task body. Used to 1044-- generate warnings for missing accepts. 1045 1046-- Entry_Bodies_Array (Node19) 1047-- Defined in protected types for which Has_Entries is true. 1048-- This is the defining identifier for the array of entry body 1049-- action procedures and barrier functions used by the runtime to 1050-- execute the user code associated with each entry. 1051 1052-- Entry_Cancel_Parameter (Node23) 1053-- Defined in blocks. This only applies to a block statement for 1054-- which the Is_Asynchronous_Call_Block flag is set. It 1055-- contains the defining identifier of an object that must be 1056-- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call 1057-- call in the cleanup handler added to the block by 1058-- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean 1059-- object for task entry calls and a Communications_Block object 1060-- in the case of protected entry calls. In both cases the objects 1061-- are declared in outer scopes to this block. 1062 1063-- Entry_Component (Node11) 1064-- Defined in formal parameters (in, in out and out parameters). Used 1065-- only for formals of entries. References the corresponding component 1066-- of the entry parameter record for the entry. 1067 1068-- Entry_Formal (Node16) 1069-- Defined in components of the record built to correspond to entry 1070-- parameters. This field points from the component to the formal. It 1071-- is the back pointer corresponding to Entry_Component. 1072 1073-- Entry_Index_Constant (Node18) 1074-- Defined in an entry index parameter. This is an identifier that 1075-- eventually becomes the name of a constant representing the index 1076-- of the entry family member whose entry body is being executed. Used 1077-- to expand references to the entry index specification identifier. 1078 1079-- Entry_Index_Type (synthesized) 1080-- Applies to an entry family. Denotes Etype of the subtype indication 1081-- in the entry declaration. Used to resolve the index expression in an 1082-- accept statement for a member of the family, and in the prefix of 1083-- 'COUNT when it applies to a family member. 1084 1085-- Contract (Node34) 1086-- Defined in entry, entry family, package, package body, subprogram and 1087-- subprogram body entities as well as their respective generic forms. A 1088-- contract is also applicable to a variable. Points to the contract of 1089-- the entity, holding various assertion items and data classifiers. 1090 1091-- Entry_Parameters_Type (Node15) 1092-- Defined in entries. Points to the access-to-record type that is 1093-- constructed by the expander to hold a reference to the parameter 1094-- values. This reference is manipulated (as an address) by the 1095-- tasking runtime. The designated record represents a packaging 1096-- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration 1097-- for further details). Entry_Parameters_Type is Empty if the entry 1098-- has no parameters. 1099 1100-- Enumeration_Pos (Uint11) 1101-- Defined in enumeration literals. Contains the position number 1102-- corresponding to the value of the enumeration literal. 1103 1104-- Enumeration_Rep (Uint12) 1105-- Defined in enumeration literals. Contains the representation that 1106-- corresponds to the value of the enumeration literal. Note that 1107-- this is normally the same as Enumeration_Pos except in the presence 1108-- of representation clauses, where Pos will still represent the 1109-- position of the literal within the type and Rep will have be the 1110-- value given in the representation clause. 1111 1112-- Enumeration_Rep_Expr (Node22) 1113-- Defined in enumeration literals. Points to the expression in an 1114-- associated enumeration rep clause that provides the representation 1115-- value for this literal. Empty if no enumeration rep clause for this 1116-- literal (or if rep clause does not have an entry for this literal, 1117-- an error situation). This is also used to catch duplicate entries 1118-- for the same literal. 1119 1120-- Enum_Pos_To_Rep (Node23) 1121-- Defined in enumeration types (but not enumeration subtypes). Set to 1122-- Empty unless the enumeration type has a non-standard representation 1123-- (i.e. at least one literal has a representation value different from 1124-- its pos value). In this case, Enum_Pos_To_Rep is the entity for an 1125-- array constructed when the type is frozen that maps Pos values to 1126-- corresponding Rep values. The index type of this array is Natural, 1127-- and the component type is a suitable integer type that holds the 1128-- full range of representation values. 1129 1130-- Equivalent_Type (Node18) 1131-- Defined in class wide types and subtypes, access to protected 1132-- subprogram types, and in exception types. For a classwide type, it 1133-- is always Empty. For a class wide subtype, it points to an entity 1134-- created by the expander which gives the backend an understandable 1135-- equivalent of the class subtype with a known size (given by an 1136-- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further 1137-- details. For E_Exception_Type, this points to the record containing 1138-- the data necessary to represent exceptions (for further details, see 1139-- System.Standard_Library. For access_to_protected subprograms, it 1140-- denotes a record that holds pointers to the operation and to the 1141-- protected object. For remote Access_To_Subprogram types, it denotes 1142-- the record that is the fat pointer representation of an RAST. 1143 1144-- Esize (Uint12) 1145-- Defined in all types and subtypes, and also for components, constants, 1146-- and variables, including exceptions where it refers to the static data 1147-- allocated for an exception. Contains the Object_Size of the type or of 1148-- the object. A value of zero indicates that the value is not yet known. 1149-- 1150-- For the case of components where a component clause is present, the 1151-- value is the value from the component clause, which must be non- 1152-- negative (but may be zero, which is acceptable for the case of 1153-- a type with only one possible value). It is also possible for Esize 1154-- of a component to be set without a component clause defined, which 1155-- means that the component size is specified, but not the position. 1156-- See also RM_Size and the section on "Handling of Type'Size Values". 1157-- During backend processing, the value is back annotated for all zero 1158-- values, so that after the call to the backend, the value is set. 1159 1160-- Etype (Node5) 1161-- Defined in all entities. Represents the type of the entity, which 1162-- is itself another entity. For a type entity, points to the parent 1163-- type for a derived type, or if the type is not derived, points to 1164-- itself. For a subtype entity, Etype points to the base type. For 1165-- a class wide type, points to the corresponding specific type. For a 1166-- subprogram or subprogram type, Etype has the return type of a function 1167-- or is set to Standard_Void_Type to represent a procedure. The Etype 1168-- field of a package is also set to Standard_Void_Type. 1169-- 1170-- Note one obscure case: for pragma Default_Storage_Pool (null), the 1171-- Etype of the N_Null node is Empty. 1172 1173-- Extra_Accessibility (Node13) 1174-- Defined in formal parameters in the non-generic case. Normally Empty, 1175-- but if expansion is active, and a parameter is one for which a 1176-- dynamic accessibility check is required, then an extra formal of type 1177-- Natural is created (see description of field Extra_Formal), and the 1178-- Extra_Accessibility field of the formal parameter points to the entity 1179-- for this extra formal. Also defined in variables when compiling 1180-- receiving stubs. In this case, a non Empty value means that this 1181-- variable's accessibility depth has been transmitted by the caller and 1182-- must be retrieved through the entity designed by this field instead of 1183-- being computed. 1184 1185-- Extra_Accessibility_Of_Result (Node19) 1186-- Defined in (non-generic) Function, Operator, and Subprogram_Type 1187-- entities. Normally Empty, but if expansion is active, and a function 1188-- is one for which "the accessibility level of the result ... determined 1189-- by the point of call" (AI05-0234) is needed, then an extra formal of 1190-- subtype Natural is created (see description of field Extra_Formal), 1191-- and the Extra_Accessibility_Of_Result field of the function points to 1192-- the entity for this extra formal. 1193 1194-- Extra_Constrained (Node23) 1195-- Defined in formal parameters in the non-generic case. Normally Empty, 1196-- but if expansion is active and a parameter is one for which a dynamic 1197-- indication of its constrained status is required, then an extra formal 1198-- of type Boolean is created (see description of field Extra_Formal), 1199-- and the Extra_Constrained field of the formal parameter points to the 1200-- entity for this extra formal. Also defined in variables when compiling 1201-- receiving stubs. In this case, a non empty value means that this 1202-- variable's constrained status has been transmitted by the caller and 1203-- must be retrieved through the entity designed by this field instead of 1204-- being computed. 1205 1206-- Extra_Formal (Node15) 1207-- Defined in formal parameters in the non-generic case. Certain 1208-- parameters require extra implicit information to be passed (e.g. the 1209-- flag indicating if an unconstrained variant record argument is 1210-- constrained, and the accessibility level for access parameters). See 1211-- description of Extra_Constrained, Extra_Accessibility fields for 1212-- further details. Extra formal parameters are constructed to represent 1213-- these values, and chained to the end of the list of formals using the 1214-- Extra_Formal field (i.e. the Extra_Formal field of the last "real" 1215-- formal points to the first extra formal, and the Extra_Formal field of 1216-- each extra formal points to the next one, with Empty indicating the 1217-- end of the list of extra formals). Another case of Extra_Formal arises 1218-- in connection with unnesting of subprograms, where the ARECnF formal 1219-- that represents an activation record pointer is an extra formal. 1220 1221-- Extra_Formals (Node28) 1222-- Applies to subprograms and subprogram types, and also to entries 1223-- and entry families. Returns first extra formal of the subprogram 1224-- or entry. Returns Empty if there are no extra formals. 1225 1226-- Finalization_Master (Node23) [root type only] 1227-- Defined in access-to-controlled or access-to-class-wide types. The 1228-- field contains the entity of the finalization master which handles 1229-- dynamically allocated controlled objects referenced by the access 1230-- type. Empty for access-to-subprogram types. Empty for access types 1231-- whose designated type does not need finalization actions. 1232 1233-- Finalize_Storage_Only (Flag158) [base type only] 1234-- Defined in all types. Set on direct controlled types to which a 1235-- valid Finalize_Storage_Only pragma applies. This flag is also set on 1236-- composite types when they have at least one controlled component and 1237-- all their controlled components are Finalize_Storage_Only. It is also 1238-- inherited by type derivation except for direct controlled types where 1239-- the Finalize_Storage_Only pragma is required at each level of 1240-- derivation. 1241 1242-- Finalizer (Node28) 1243-- Applies to package declarations and bodies. Contains the entity of the 1244-- library-level program which finalizes all package-level controlled 1245-- objects. 1246 1247-- First_Component (synthesized) 1248-- Applies to record types. Returns the first component by following the 1249-- chain of declared entities for the record until a component is found 1250-- (one with an Ekind of E_Component). The discriminants are skipped. If 1251-- the record is null, then Empty is returned. 1252 1253-- First_Component_Or_Discriminant (synthesized) 1254-- Similar to First_Component, but discriminants are not skipped, so will 1255-- find the first discriminant if discriminants are present. 1256 1257-- First_Entity (Node17) 1258-- Defined in all entities which act as scopes to which a list of 1259-- associated entities is attached (blocks, class subtypes and types, 1260-- entries, functions, loops, packages, procedures, protected objects, 1261-- record types and subtypes, private types, task types and subtypes). 1262-- Points to a list of associated entities using the Next_Entity field 1263-- as a chain pointer with Empty marking the end of the list. 1264 1265-- First_Exit_Statement (Node8) 1266-- Defined in E_Loop entity. The exit statements for a loop are chained 1267-- (in reverse order of appearance) using this field to point to the 1268-- first entry in the chain (last exit statement in the loop). The 1269-- entries are chained through the Next_Exit_Statement field of the 1270-- N_Exit_Statement node with Empty marking the end of the list. 1271 1272-- First_Formal (synthesized) 1273-- Applies to subprograms and subprogram types, and also to entries 1274-- and entry families. Returns first formal of the subprogram or entry. 1275-- The formals are the first entities declared in a subprogram or in 1276-- a subprogram type (the designated type of an Access_To_Subprogram 1277-- definition) or in an entry. 1278 1279-- First_Formal_With_Extras (synthesized) 1280-- Applies to subprograms and subprogram types, and also in entries 1281-- and entry families. Returns first formal of the subprogram or entry. 1282-- Returns Empty if there are no formals. The list returned includes 1283-- all the extra formals (see description of Extra_Formals field). 1284 1285-- First_Index (Node17) 1286-- Defined in array types and subtypes. By introducing implicit subtypes 1287-- for the index constraints, we have the same structure for constrained 1288-- and unconstrained arrays, subtype marks and discrete ranges are 1289-- both represented by a subtype. This function returns the tree node 1290-- corresponding to an occurrence of the first index (NOT the entity for 1291-- the type). Subsequent indices are obtained using Next_Index. Note that 1292-- this field is defined for the case of string literal subtypes, but is 1293-- always Empty. 1294 1295-- First_Literal (Node17) 1296-- Defined in all enumeration types, including character and boolean 1297-- types. This field points to the first enumeration literal entity 1298-- for the type (i.e. it is set to First (Literals (N)) where N is 1299-- the enumeration type definition node. A special case occurs with 1300-- standard character and wide character types, where this field is 1301-- Empty, since there are no enumeration literal lists in these cases. 1302-- Note that this field is set in enumeration subtypes, but it still 1303-- points to the first literal of the base type in this case. 1304 1305-- First_Private_Entity (Node16) 1306-- Defined in all entities containing private parts (packages, protected 1307-- types and subtypes, task types and subtypes). The entities on the 1308-- entity chain are in order of declaration, so the entries for private 1309-- entities are at the end of the chain. This field points to the first 1310-- entity for the private part. It is Empty if there are no entities 1311-- declared in the private part or if there is no private part. 1312 1313-- First_Rep_Item (Node6) 1314-- Defined in all entities. If non-empty, points to a linked list of 1315-- representation pragmas nodes and representation clause nodes that 1316-- apply to the entity, linked using Next_Rep_Item, with Empty marking 1317-- the end of the list. In the case of derived types and subtypes, the 1318-- new entity inherits the chain at the point of declaration. This means 1319-- that it is possible to have multiple instances of the same kind of rep 1320-- item on the chain, in which case it is the first one that applies to 1321-- the entity. 1322-- 1323-- Note: pragmas that can apply to more than one overloadable entity, 1324-- (Convention, Interface, Inline, Inline_Always, Import, Export, 1325-- External) are never present on this chain when they apply to 1326-- overloadable entities, since it is impossible for a given pragma 1327-- to be on more than one chain at a time. 1328-- 1329-- For most representation items, the representation information is 1330-- reflected in other fields and flags in the entity. For example if a 1331-- record representation clause is present, the component entities 1332-- reflect the specified information. However, there are some items that 1333-- are only reflected in the chain. These include: 1334-- 1335-- Machine_Attribute pragma 1336-- Link_Alias pragma 1337-- Linker_Constructor pragma 1338-- Linker_Destructor pragma 1339-- Weak_External pragma 1340-- Thread_Local_Storage pragma 1341-- 1342-- If any of these items are present, then the flag Has_Gigi_Rep_Item is 1343-- set, indicating that the backend should search the chain. 1344-- 1345-- Other representation items are included in the chain so that error 1346-- messages can easily locate the relevant nodes for posting errors. 1347-- Note in particular that size clauses are defined only for this 1348-- purpose, and should only be accessed if Has_Size_Clause is set. 1349 1350-- Float_Rep (Uint10) 1351-- Defined in floating-point entities. Contains a value of type 1352-- Float_Rep_Kind. Together with the Digits_Value uniquely defines 1353-- the floating-point representation to be used. 1354 1355-- Freeze_Node (Node7) 1356-- Defined in all entities. If there is an associated freeze node for the 1357-- entity, this field references this freeze node. If no freeze node is 1358-- associated with the entity, then this field is Empty. See package 1359-- Freeze for further details. 1360 1361-- From_Limited_With (Flag159) 1362-- Defined in abtract states, package and type entities. Set to True when 1363-- the related entity is generated by the expansion of a limited with 1364-- clause. Such an entity is said to be a "shadow" - it acts as the 1365-- abstract view of a state or variable or as the incomplete view of a 1366-- type by inheriting relevant attributes from the said entity. 1367 1368-- Full_View (Node11) 1369-- Defined in all type and subtype entities and in deferred constants. 1370-- References the entity for the corresponding full type or constant 1371-- declaration. For all types other than private and incomplete types, 1372-- this field always contains Empty. If an incomplete type E1 is 1373-- completed by a private type E2 whose full type declaration entity is 1374-- E3 then the full view of E1 is E2, and the full view of E2 is E3. See 1375-- also Underlying_Type. 1376 1377-- Generic_Homonym (Node11) 1378-- Defined in generic packages. The generic homonym is the entity of 1379-- a renaming declaration inserted in every generic unit. It is used 1380-- to resolve the name of a local entity that is given by a qualified 1381-- name, when the generic entity itself is hidden by a local name. 1382 1383-- Generic_Renamings (Elist23) 1384-- Defined in package and subprogram instances. Holds mapping that 1385-- associates generic parameters with the corresponding instances, in 1386-- those cases where the instance is an entity. 1387 1388-- Handler_Records (List10) 1389-- Defined in subprogram and package entities. Points to a list of 1390-- identifiers referencing the handler record entities for the 1391-- corresponding unit. 1392 1393-- Has_Aliased_Components (Flag135) [implementation base type only] 1394-- Defined in array type entities. Indicates that the component type 1395-- of the array is aliased. 1396 1397-- Has_Alignment_Clause (Flag46) 1398-- Defined in all type entities and objects. Indicates if an alignment 1399-- clause has been given for the entity. If set, then Alignment_Clause 1400-- returns the N_Attribute_Definition node for the alignment attribute 1401-- definition clause. Note that it is possible for this flag to be False 1402-- even when Alignment_Clause returns non_Empty (this happens in the case 1403-- of derived type declarations). 1404 1405-- Has_All_Calls_Remote (Flag79) 1406-- Defined in all library unit entities. Set if the library unit has an 1407-- All_Calls_Remote pragma. Note that such entities must also be RCI 1408-- entities, so the flag Is_Remote_Call_Interface will always be set if 1409-- this flag is set. 1410 1411-- Has_Anonymous_Master (Flag253) 1412-- Defined in units (top-level functions and procedures, library-level 1413-- packages). Set if the associated unit contains a heterogeneous 1414-- finalization master. The master's name is of the form <unit>AM and it 1415-- services anonymous access-to-controlled types with an undetermined 1416-- lifetime. 1417 1418-- Has_Atomic_Components (Flag86) [implementation base type only] 1419-- Defined in all types and objects. Set only for an array type or 1420-- an array object if a valid pragma Atomic_Components applies to the 1421-- type or object. Note that in the case of an object, this flag is 1422-- only set on the object if there was an explicit pragma for the 1423-- object. In other words, the proper test for whether an object has 1424-- atomic components is to see if either the object or its base type 1425-- has this flag set. Note that in the case of a type, the pragma will 1426-- be chained to the rep item chain of the first subtype in the usual 1427-- manner. 1428 1429-- Has_Attach_Handler (synthesized) 1430-- Applies to record types that are constructed by the expander to 1431-- represent protected types. Returns True if there is at least one 1432-- Attach_Handler pragma in the corresponding specification. 1433 1434-- Has_Biased_Representation (Flag139) 1435-- Defined in discrete types (where it applies to the type'size value), 1436-- and to objects (both stand-alone and components), where it applies to 1437-- the size of the object from a size or record component clause. In 1438-- all cases it indicates that the size in question is smaller than 1439-- would normally be required, but that the size requirement can be 1440-- satisfied by using a biased representation, in which stored values 1441-- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to 1442-- reduce the required size. For example, a type with a range of 1..2 1443-- takes one bit, using 0 to represent 1 and 1 to represent 2. 1444-- 1445-- Note that in the object and component cases, the flag is only set if 1446-- the type is unbiased, but the object specifies a smaller size than the 1447-- size of the type, forcing biased representation for the object, but 1448-- the subtype is still an unbiased type. 1449 1450-- Has_Completion (Flag26) 1451-- Defined in all entities that require a completion (functions, 1452-- procedures, private types, limited private types, incomplete types, 1453-- constants and packages that require a body). The flag is set if the 1454-- completion has been encountered and analyzed. 1455 1456-- Has_Completion_In_Body (Flag71) 1457-- Defined in all entities for types and subtypes. Set only in "Taft 1458-- amendment types" (incomplete types whose full declaration appears in 1459-- the package body). 1460 1461-- Has_Complex_Representation (Flag140) [implementation base type only] 1462-- Defined in all type entities. Set only for a record base type to 1463-- which a valid pragma Complex_Representation applies. 1464 1465-- Has_Component_Size_Clause (Flag68) [implementation base type only] 1466-- Defined in all type entities. Set if a component size clause is 1467-- Defined for the given type. Note that this flag can be False even 1468-- if Component_Size is non-zero (happens in the case of derived types). 1469 1470-- Has_Constrained_Partial_View (Flag187) 1471-- Defined in private type and their completions, when the private 1472-- type has no discriminants and the full view has discriminants with 1473-- defaults. In Ada 2005 heap-allocated objects of such types are not 1474-- constrained, and can change their discriminants with full assignment. 1475-- 1476-- Ada 2012 has an additional rule (3.3. (23/10.3)) concerning objects 1477-- declared in a generic package body. Objects whose type is an untagged 1478-- generic formal private type are considered to have a constrained 1479-- partial view. The predicate Object_Type_Has_Constrained_Partial_View 1480-- in sem_aux is used to test for this case. 1481 1482-- Has_Contiguous_Rep (Flag181) 1483-- Defined in enumeration types. Set if the type as a representation 1484-- clause whose entries are successive integers. 1485 1486-- Has_Controlling_Result (Flag98) 1487-- Defined in E_Function entities. Set if the function is a primitive 1488-- function of a tagged type which can dispatch on result. 1489 1490-- Has_Controlled_Component (Flag43) [base type only] 1491-- Defined in all type and subtype entities. Set only for composite type 1492-- entities which contain a component that either is a controlled type, 1493-- or itself contains controlled component (i.e. either Is_Controlled or 1494-- Has_Controlled_Component is set for at least one component). 1495 1496-- Has_Convention_Pragma (Flag119) 1497-- Defined in all entities. Set for an entity for which a valid pragma 1498-- Convention, Import, or Export has been given. Used to prevent more 1499-- than one such pragma appearing for a given entity (RM B.1(45)). 1500 1501-- Has_Default_Aspect (Flag39) [base type only] 1502-- Defined in entities for types and subtypes, set for scalar types with 1503-- a Default_Value aspect and array types with a Default_Component_Value 1504-- apsect. If this flag is set, then a corresponding aspect specification 1505-- node will be present on the rep item chain for the entity. 1506 1507-- Has_Default_Init_Cond (Flag3) 1508-- Defined in type and subtype entities. Set if pragma Default_Initial_ 1509-- Condition applies to the type or subtype. This flag must be mutually 1510-- exclusive with Has_Inherited_Default_Init_Cond. 1511 1512-- Has_Delayed_Aspects (Flag200) 1513-- Defined in all entities. Set if the Rep_Item chain for the entity has 1514-- one or more N_Aspect_Definition nodes chained which are not to be 1515-- evaluated till the freeze point. The aspect definition expression 1516-- clause has been preanalyzed to get visibility at the point of use, 1517-- but no other action has been taken. 1518 1519-- Has_Delayed_Freeze (Flag18) 1520-- Defined in all entities. Set to indicate that an explicit freeze 1521-- node must be generated for the entity at its freezing point. See 1522-- separate section ("Delayed Freezing and Elaboration") for details. 1523 1524-- Has_Delayed_Rep_Aspects (Flag261) 1525-- Defined in all type and subtypes. This flag is set if there is at 1526-- least one aspect for a representation characteristic that has to be 1527-- delayed and is one of the characteristics that may be inherited by 1528-- types derived from this type if not overridden. If this flag is set, 1529-- then types derived from this type have May_Inherit_Delayed_Rep_Aspects 1530-- set, signalling that Freeze.Inhert_Delayed_Rep_Aspects must be called 1531-- at the freeze point of the derived type. 1532 1533-- Has_Discriminants (Flag5) 1534-- Defined in all types and subtypes. For types that are allowed to have 1535-- discriminants (record types and subtypes, task types and subtypes, 1536-- protected types and subtypes, private types, limited private types, 1537-- and incomplete types), indicates if the corresponding type or subtype 1538-- has a known discriminant part. Always false for all other types. 1539 1540-- Has_Dispatch_Table (Flag220) 1541-- Defined in E_Record_Types that are tagged. Set to indicate that the 1542-- corresponding dispatch table is already built. This flag is used to 1543-- avoid duplicate construction of library level dispatch tables (because 1544-- the declaration of library level objects cause premature construction 1545-- of the table); otherwise the code that builds the table is added at 1546-- the end of the list of declarations of the package. 1547 1548-- Has_Dynamic_Predicate_Aspect (Flag258) 1549-- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect 1550-- was explicitly applied to the type. Generally we treat predicates as 1551-- static if possible, regardless of whether they are specified using 1552-- Predicate, Static_Predicate, or Dynamic_Predicate. And if a predicate 1553-- can be treated as static (i.e. its expression is predicate-static), 1554-- then the flag Has_Static_Predicate will be set True. But there are 1555-- cases where legality is affected by the presence of an explicit 1556-- Dynamic_Predicate aspect. For example, even if a predicate looks 1557-- static, you can't use it in a case statement if there is an explicit 1558-- Dynamic_Predicate aspect specified. So test Has_Static_Predicate if 1559-- you just want to know if the predicate can be evaluated statically, 1560-- but test Has_Dynamic_Predicate_Aspect to enforce legality rules about 1561-- the use of dynamic predicates. 1562 1563-- Has_Entries (synthesized) 1564-- Applies to concurrent types. True if any entries are declared 1565-- within the task or protected definition for the type. 1566 1567-- Has_Enumeration_Rep_Clause (Flag66) 1568-- Defined in enumeration types. Set if an enumeration representation 1569-- clause has been given for this enumeration type. Used to prevent more 1570-- than one enumeration representation clause for a given type. Note 1571-- that this does not imply a representation with holes, since the rep 1572-- clause may merely confirm the default 0..N representation. 1573 1574-- Has_Exit (Flag47) 1575-- Defined in loop entities. Set if the loop contains an exit statement. 1576 1577-- Has_Expanded_Contract (Flag240) 1578-- Defined in functions, procedures, entries, and entry families. Set 1579-- when a subprogram has a N_Contract node that has been expanded. The 1580-- flag prevents double expansion of a contract when a construct is 1581-- rewritten into something else and subsequently reanalyzed/expanded. 1582 1583-- Has_Foreign_Convention (synthesized) 1584-- Applies to all entities. Determines if the Convention for the 1585-- entity is a foreign convention (i.e. is other than Convention_Ada, 1586-- Convention_Intrinsic, Convention_Entry or Convention_Protected). 1587 1588-- Has_Forward_Instantiation (Flag175) 1589-- Defined in package entities. Set for packages that instantiate local 1590-- generic entities before the corresponding generic body has been seen. 1591-- If a package has a forward instantiation, we cannot inline subprograms 1592-- appearing in the same package because the placement requirements of 1593-- the instance will conflict with the linear elaboration of front-end 1594-- inlining. 1595 1596-- Has_Fully_Qualified_Name (Flag173) 1597-- Defined in all entities. Set if the name in the Chars field has been 1598-- replaced by the fully qualified name, as used for debug output. See 1599-- Exp_Dbug for a full description of the use of this flag and also the 1600-- related flag Has_Qualified_Name. 1601 1602-- Has_Gigi_Rep_Item (Flag82) 1603-- Defined in all entities. Set if the rep item chain (referenced by 1604-- First_Rep_Item and linked through the Next_Rep_Item chain) contains a 1605-- representation item that needs to be specially processed by the back 1606-- end, i.e. one of the following items: 1607-- 1608-- Machine_Attribute pragma 1609-- Linker_Alias pragma 1610-- Linker_Constructor pragma 1611-- Linker_Destructor pragma 1612-- Weak_External pragma 1613-- Thread_Local_Storage pragma 1614-- 1615-- If this flag is set, then the backend should scan the rep item chain 1616-- to process any of these items that appear. At least one such item will 1617-- be present. 1618-- 1619-- Has_Homonym (Flag56) 1620-- Defined in all entities. Set if an entity has a homonym in the same 1621-- scope. Used by the backend to generate unique names for all entities. 1622 1623-- Has_Implicit_Dereference (Flag251) 1624-- Defined in types and discriminants. Set if the type has an aspect 1625-- Implicit_Dereference. Set also on the discriminant named in the aspect 1626-- clause, to simplify type resolution. 1627 1628-- Has_Independent_Components (Flag34) [implementation base type only] 1629-- Defined in all types and objects. Set only for a record type or an 1630-- array type or array object if a valid pragma Independent_Components 1631-- applies to the type or object. Note that in the case of an object, 1632-- this flag is only set on the object if there was an explicit pragma 1633-- for the object. In other words, the proper test for whether an object 1634-- has independent components is to see if either the object or its base 1635-- type has this flag set. Note that in the case of a type, the pragma 1636-- will be chained to the rep item chain of the first subtype in the 1637-- usual manner. 1638 1639-- Has_Inheritable_Invariants (Flag248) 1640-- Defined in all type entities. Set in private types from which one 1641-- or more Invariant'Class aspects will be inherited if a another type is 1642-- derived from the type (i.e. those types which have an Invariant'Class 1643-- aspect, or which inherit one or more Invariant'Class aspects). Also 1644-- set in the corresponding full types. Note that it might be the full 1645-- type which has inheritable invariants, and in this case the flag will 1646-- also be set in the private type. 1647 1648-- Has_Inherited_Default_Init_Cond (Flag133) 1649-- Defined in type and subtype entities. Set if a derived type inherits 1650-- pragma Default_Initial_Condition from its parent type. This flag must 1651-- be mutually exclusive with Had_Default_Init_Cond. 1652 1653-- Has_Initial_Value (Flag219) 1654-- Defined in entities for variables and out parameters. Set if there 1655-- is an explicit initial value expression in the declaration of the 1656-- variable. Note that this is set only if this initial value is 1657-- explicit, it is not set for the case of implicit initialization 1658-- of access types or controlled types. Always set to False for out 1659-- parameters. Also defined in entities for in and in-out parameters, 1660-- but always false in these cases. 1661 1662-- Has_Interrupt_Handler (synthesized) 1663-- Applies to all protected type entities. Set if the protected type 1664-- definition contains at least one procedure to which a pragma 1665-- Interrupt_Handler applies. 1666 1667-- Has_Invariants (Flag232) 1668-- Defined in all type entities and in subprogram entities. Set in 1669-- private types if an Invariant or Invariant'Class aspect applies to the 1670-- type, or if the type inherits one or more Invariant'Class aspects. 1671-- Also set in the corresponding full type. Note: if this flag is set 1672-- True, then usually the Invariant_Procedure attribute is set once the 1673-- type is frozen, however this may not be true in some error situations. 1674-- Note that it might be the full type which has inheritable invariants, 1675-- and then the flag will also be set in the private type. 1676 1677-- Has_Loop_Entry_Attributes (Flag260) 1678-- Defined in E_Loop entities. Set when the loop is subject to at least 1679-- one attribute 'Loop_Entry. The flag also implies that the loop has 1680-- already been transformed. See Expand_Loop_Entry_Attribute for details. 1681 1682-- Has_Machine_Radix_Clause (Flag83) 1683-- Defined in decimal types and subtypes, set if a Machine_Radix 1684-- representation clause is present. This flag is used to detect 1685-- the error of multiple machine radix clauses for a single type. 1686 1687-- Has_Master_Entity (Flag21) 1688-- Defined in entities that can appear in the scope stack (see spec 1689-- of Sem). It is set if a task master entity (_master) has been 1690-- declared and initialized in the corresponding scope. 1691 1692-- Has_Missing_Return (Flag142) 1693-- Defined in functions and generic functions. Set if there is one or 1694-- more missing return statements in the function. This is used to 1695-- control wrapping of the body in Exp_Ch6 to ensure that the program 1696-- error exception is correctly raised in this case at runtime. 1697 1698-- Has_Nested_Block_With_Handler (Flag101) 1699-- Defined in scope entities. Set if there is a nested block within the 1700-- scope that has an exception handler and the two scopes are in the 1701-- same procedure. This is used by the backend for controlling certain 1702-- optimizations to ensure that they are consistent with exceptions. 1703-- See documentation in backend for further details. 1704 1705-- Has_Nested_Subprogram (Flag282) 1706-- Defined in subprogram entities. Set for a subprogram which contains at 1707-- least one nested subprogram. 1708 1709 -- Has_Non_Null_Refinement (synth) 1710-- Defined in E_Abstract_State entities. True if the state has at least 1711-- one variable or state constituent in aspect/pragma Refined_State. 1712 1713-- Has_Non_Standard_Rep (Flag75) [implementation base type only] 1714-- Defined in all type entities. Set when some representation clause 1715-- or pragma causes the representation of the item to be significantly 1716-- modified. In this category are changes of small or radix for a 1717-- fixed-point type, change of component size for an array, and record 1718-- or enumeration representation clauses, as well as packed pragmas. 1719-- All other representation clauses (e.g. Size and Alignment clauses) 1720-- are not considered to be significant since they do not affect 1721-- stored bit patterns. 1722 1723-- Has_Null_Abstract_State (synth) 1724-- Defined in package entities. True if the package is subject to a null 1725-- Abstract_State aspect/pragma. 1726 1727-- Has_Null_Refinement (synth) 1728-- Defined in E_Abstract_State entities. True if the state has a null 1729-- refinement in aspect/pragma Refined_State. 1730 1731-- Has_Object_Size_Clause (Flag172) 1732-- Defined in entities for types and subtypes. Set if an Object_Size 1733-- clause has been processed for the type Used to prevent multiple 1734-- Object_Size clauses for a given entity. 1735 1736-- Has_Out_Or_In_Out_Parameter (Flag110) 1737-- Present in function and generic function entities. Set if the function 1738-- has at least one OUT or IN OUT parameter (allowed only in Ada 2012). 1739 1740-- Has_Per_Object_Constraint (Flag154) 1741-- Defined in E_Component entities. Set if the subtype of the component 1742-- has a per object constraint. Per object constraints result from the 1743-- following situations : 1744-- 1745-- 1. N_Attribute_Reference - when the prefix is the enclosing type and 1746-- the attribute is Access. 1747-- 2. N_Discriminant_Association - when the expression uses the 1748-- discriminant of the enclosing type. 1749-- 3. N_Index_Or_Discriminant_Constraint - when at least one of the 1750-- individual constraints is a per object constraint. 1751-- 4. N_Range - when the lower or upper bound uses the discriminant of 1752-- the enclosing type. 1753-- 5. N_Range_Constraint - when the range expression uses the 1754-- discriminant of the enclosing type. 1755 1756-- Has_Pragma_Controlled (Flag27) [implementation base type only] 1757-- Defined in access type entities. It is set if a pragma Controlled 1758-- applies to the access type. 1759 1760-- Has_Pragma_Elaborate_Body (Flag150) 1761-- Defined in all entities. Set in compilation unit entities if a 1762-- pragma Elaborate_Body applies to the compilation unit. 1763 1764-- Has_Pragma_Inline (Flag157) 1765-- Defined in all entities. Set for functions and procedures for which a 1766-- pragma Inline or Inline_Always applies to the subprogram. Note that 1767-- this flag can be set even if Is_Inlined is not set. This happens for 1768-- pragma Inline (if Inline_Active is False). In other words, the flag 1769-- Has_Pragma_Inline represents the formal semantic status, and is used 1770-- for checking semantic correctness. The flag Is_Inlined indicates 1771-- whether inlining is actually active for the entity. 1772 1773-- Has_Pragma_Inline_Always (Flag230) 1774-- Defined in all entities. Set for functions and procedures for which a 1775-- pragma Inline_Always applies. Note that if this flag is set, the flag 1776-- Has_Pragma_Inline is also set. 1777 1778-- Has_Pragma_No_Inline (Flag201) 1779-- Defined in all entities. Set for functions and procedures for which a 1780-- pragma No_Inline applies. Note that if this flag is set, the flag 1781-- Has_Pragma_Inline_Always cannot be set. 1782 1783-- Has_Pragma_Ordered (Flag198) [implementation base type only] 1784-- Defined in entities for enumeration types. If set indicates that a 1785-- valid pragma Ordered was given for the type. This flag is inherited 1786-- by derived enumeration types. We don't need to distinguish the derived 1787-- case since we allow multiple occurrences of this pragma anyway. 1788 1789-- Has_Pragma_Pack (Flag121) [implementation base type only] 1790-- Defined in array and record type entities. If set, indicates that a 1791-- valid pragma Pack was given for the type. Note that this flag is not 1792-- inherited by derived type. See also the Is_Packed flag. 1793 1794-- Has_Pragma_Pure (Flag203) 1795-- Defined in all entities. If set, indicates that a valid pragma Pure 1796-- was given for the entity. In some cases, we need to test whether 1797-- Is_Pure was explicitly set using this pragma. 1798 1799-- Has_Pragma_Preelab_Init (Flag221) 1800-- Defined in type and subtype entities. If set indicates that a valid 1801-- pragma Preelaborable_Initialization applies to the type. 1802 1803-- Has_Pragma_Pure_Function (Flag179) 1804-- Defined in all entities. If set, indicates that a valid pragma 1805-- Pure_Function was given for the entity. In some cases, we need to 1806-- know that Is_Pure was explicitly set using this pragma. We also set 1807-- this flag for some internal entities that we know should be treated 1808-- as pure for optimization purposes. 1809 1810-- Has_Pragma_Thread_Local_Storage (Flag169) 1811-- Defined in all entities. If set, indicates that a valid pragma 1812-- Thread_Local_Storage was given for the entity. 1813 1814-- Has_Pragma_Unmodified (Flag233) 1815-- Defined in all entities. Can only be set for variables (E_Variable, 1816-- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified 1817-- applies to the variable, indicating that no warning should be given 1818-- if the entity is never modified. Note that clients should generally 1819-- not test this flag directly, but instead use function Has_Unmodified. 1820 1821-- Has_Pragma_Unreferenced (Flag180) 1822-- Defined in all entities. Set if a valid pragma Unreferenced applies 1823-- to the entity, indicating that no warning should be given if the 1824-- entity has no references, but a warning should be given if it is 1825-- in fact referenced. For private types, this flag is set in both the 1826-- private entity and full entity if the pragma applies to either. Note 1827-- that clients should generally not test this flag directly, but instead 1828-- use function Has_Unreferenced. 1829 1830-- Has_Pragma_Unreferenced_Objects (Flag212) 1831-- Defined in type and subtype entities. Set if a valid pragma 1832-- Unreferenced_Objects applies to the type, indicating that no warning 1833-- should be given for objects of such a type for being unreferenced 1834-- (but unlike the case with pragma Unreferenced, it is ok to reference 1835-- such an object and no warning is generated. 1836 1837-- Has_Predicates (Flag250) 1838-- Defined in type and subtype entities. Set if a pragma Predicate or 1839-- Predicate aspect applies to the type or subtype, or if it inherits a 1840-- Predicate aspect from its parent or progenitor types. 1841 1842-- Has_Primitive_Operations (Flag120) [base type only] 1843-- Defined in all type entities. Set if at least one primitive operation 1844-- is defined for the type. 1845 1846-- Has_Private_Ancestor (Flag151) 1847-- Applies to type extensions. True if some ancestor is derived from a 1848-- private type, making some components invisible and aggregates illegal. 1849-- This flag is set at the point of derivation. The legality of the 1850-- aggregate must be rechecked because it also depends on the visibility 1851-- at the point the aggregate is resolved. See sem_aggr.adb. This is part 1852-- of AI05-0115. 1853 1854-- Has_Private_Declaration (Flag155) 1855-- Defined in all entities. Set if it is the defining entity of a private 1856-- type declaration or its corresponding full declaration. This flag is 1857-- thus preserved when the full and the partial views are exchanged, to 1858-- indicate if a full type declaration is a completion. Used for semantic 1859-- checks in E.4(18) and elsewhere. 1860 1861-- Has_Protected (Flag271) [base type only] 1862-- Defined in all type entities. Set on protected types themselves, and 1863-- also (recursively) on any composite type which has a component for 1864-- which Has_Protected is set. The meaning is that an allocator for 1865-- or declaration of such an object must create the required protected 1866-- objects. Note: the flag is not set on access types, even if they 1867-- designate an object that Has_Protected. 1868 1869-- Has_Qualified_Name (Flag161) 1870-- Defined in all entities. Set if the name in the Chars field has 1871-- been replaced by its qualified name, as used for debug output. See 1872-- Exp_Dbug for a full description of qualification requirements. For 1873-- some entities, the name is the fully qualified name, but there are 1874-- exceptions. In particular, for local variables in procedures, we 1875-- do not include the procedure itself or higher scopes. See also the 1876-- flag Has_Fully_Qualified_Name, which is set if the name does indeed 1877-- include the fully qualified name. 1878 1879-- Has_RACW (Flag214) 1880-- Defined in package spec entities. Set if the spec contains the 1881-- declaration of a remote access-to-classwide type. 1882 1883-- Has_Record_Rep_Clause (Flag65) [implementation base type only] 1884-- Defined in record types. Set if a record representation clause has 1885-- been given for this record type. Used to prevent more than one such 1886-- clause for a given record type. Note that this is initially cleared 1887-- for a derived type, even though the representation is inherited. See 1888-- also the flag Has_Specified_Layout. 1889 1890-- Has_Recursive_Call (Flag143) 1891-- Defined in procedures. Set if a direct parameterless recursive call 1892-- is detected while analyzing the body. Used to activate some error 1893-- checks for infinite recursion. 1894 1895-- Has_Shift_Operator (Flag267) [base type only] 1896-- Defined in integer types. Set in the base type of an integer type for 1897-- which at least one of the shift operators is defined. 1898 1899-- Has_Size_Clause (Flag29) 1900-- Defined in entities for types and objects. Set if a size clause is 1901-- defined for the entity. Used to prevent multiple Size clauses for a 1902-- given entity. Note that it is always initially cleared for a derived 1903-- type, even though the Size for such a type is inherited from a Size 1904-- clause given for the parent type. 1905 1906-- Has_Small_Clause (Flag67) 1907-- Defined in ordinary fixed point types (but not subtypes). Indicates 1908-- that a small clause has been given for the entity. Used to prevent 1909-- multiple Small clauses for a given entity. Note that it is always 1910-- initially cleared for a derived type, even though the Small for such 1911-- a type is inherited from a Small clause given for the parent type. 1912 1913-- Has_Specified_Layout (Flag100) [implementation base type only] 1914-- Defined in all type entities. Set for a record type or subtype if 1915-- the record layout has been specified by a record representation 1916-- clause. Note that this differs from the flag Has_Record_Rep_Clause 1917-- in that it is inherited by a derived type. Has_Record_Rep_Clause is 1918-- used to indicate that the type is mentioned explicitly in a record 1919-- representation clause, and thus is not inherited by a derived type. 1920-- This flag is always False for non-record types. 1921 1922-- Has_Specified_Stream_Input (Flag190) 1923-- Has_Specified_Stream_Output (Flag191) 1924-- Has_Specified_Stream_Read (Flag192) 1925-- Has_Specified_Stream_Write (Flag193) 1926-- Defined in all type and subtype entities. Set for a given view if the 1927-- corresponding stream-oriented attribute has been defined by an 1928-- attribute definition clause. When such a clause occurs, a TSS is set 1929-- on the underlying full view; the flags are used to track visibility of 1930-- the attribute definition clause for partial or incomplete views. 1931 1932-- Has_Static_Discriminants (Flag211) 1933-- Defined in record subtypes constrained by discriminant values. Set if 1934-- all the discriminant values have static values, meaning that in the 1935-- case of a variant record, the component list can be trimmed down to 1936-- include only the components corresponding to these discriminants. 1937 1938-- Has_Static_Predicate (Flag269) 1939-- Defined in all types and subtypes. Set if the type (which must be a 1940-- scalar type) has a predicate whose expression is predicate-static. 1941-- This can result from the use of any Predicate, Static_Predicate, or 1942-- Dynamic_Predicate aspect. We can distinguish these cases by testing 1943-- Has_Static_Predicate_Aspect and Has_Dynamic_Predicate_Aspect. See 1944-- description of the latter flag for further information on dynamic 1945-- predicates which are also static. 1946 1947-- Has_Static_Predicate_Aspect (Flag259) 1948-- Defined in all types and subtypes. Set if a Static_Predicate aspect 1949-- applies to the type. Note that we can tell if a static predicate is 1950-- present by looking at Has_Static_Predicate, but this could have come 1951-- from a Predicate aspect or pragma or even from a Dynamic_Predicate 1952-- aspect. When we need to know the difference (e.g. to know what set of 1953-- check policies apply, use this flag and Has_Dynamic_Predicate_Aspect 1954-- to determine which case we have). 1955 1956-- Has_Storage_Size_Clause (Flag23) [implementation base type only] 1957-- Defined in task types and access types. It is set if a Storage_Size 1958-- clause is present for the type. Used to prevent multiple clauses for 1959-- one type. Note that this flag is initially cleared for a derived type 1960-- even though the Storage_Size for such a type is inherited from a 1961-- Storage_Size clause given for the parent type. Note that in the case 1962-- of access types, this flag is defined only in the root type, since a 1963-- storage size clause cannot be given to a derived type. 1964 1965-- Has_Stream_Size_Clause (Flag184) 1966-- Defined in all entities. It is set for types which have a Stream_Size 1967-- clause attribute. Used to prevent multiple Stream_Size clauses for a 1968-- given entity, and also whether it is necessary to check for a stream 1969-- size clause. 1970 1971-- Has_Task (Flag30) [base type only] 1972-- Defined in all type entities. Set on task types themselves, and also 1973-- (recursively) on any composite type which has a component for which 1974-- Has_Task is set. The meaning is that an allocator or declaration of 1975-- such an object must create the required tasks. Note: the flag is not 1976-- set on access types, even if they designate an object that Has_Task. 1977 1978-- Has_Thunks (Flag228) 1979-- Applies to E_Constant entities marked Is_Tag. True for secondary tag 1980-- referencing a dispatch table whose contents are pointers to thunks. 1981 1982-- Has_Unchecked_Union (Flag123) [base type only] 1983-- Defined in all type entities. Set on unchecked unions themselves 1984-- and (recursively) on any composite type which has a component for 1985-- which Has_Unchecked_Union is set. The meaning is that a comparison 1986-- operation or 'Valid_Scalars reference for the type is not permitted. 1987-- Note that the flag is not set on access types, even if they designate 1988-- an object that has the flag Has_Unchecked_Union set. 1989 1990-- Has_Unknown_Discriminants (Flag72) 1991-- Defined in all entities. Set for types with unknown discriminants. 1992-- Types can have unknown discriminants either from their declaration or 1993-- through type derivation. The use of this flag exactly meets the spec 1994-- in RM 3.7(26). Note that all class-wide types are considered to have 1995-- unknown discriminants. Note that both flags Has_Discriminants and 1996-- Has_Unknown_Discriminants may be true for a type. Class-wide types and 1997-- their subtypes have unknown discriminants and can have declared ones 1998-- as well. Private types declared with unknown discriminants may have a 1999-- full view that has explicit discriminants, and both flag will be set 2000-- on the partial view, to insure that discriminants are properly 2001-- inherited in certain contexts. 2002 2003-- Has_Uplevel_Reference (Flag215) 2004-- Defined in all entities. Indicates that the entity is locally defined 2005-- within a subprogram P, and there is a reference to the entity within 2006-- a subprogram nested within P (at any depth). Set only for the VM case 2007-- (where it is set for variables, constants and loop parameters), and in 2008-- the case where we are unnesting nested subprograms (in which case it 2009-- is also set for types and subtypes which are not static types, and 2010-- that are referenced uplevel, as well as for subprograms that contain 2011-- uplevel references or call other subprograms (Exp_Unst has details). 2012 2013-- Has_Visible_Refinement (Flag263) 2014-- Defined in E_Abstract_State entities. Set when a state has at least 2015-- one refinement constituent and analysis is in the region between 2016-- pragma Refined_State and the end of the package body declarations. 2017 2018-- Has_Volatile_Components (Flag87) [implementation base type only] 2019-- Defined in all types and objects. Set only for an array type or array 2020-- object if a valid pragma Volatile_Components or a valid pragma 2021-- Atomic_Components applies to the type or object. Note that in the case 2022-- of an object, this flag is only set on the object if there was an 2023-- explicit pragma for the object. In other words, the proper test for 2024-- whether an object has volatile components is to see if either the 2025-- object or its base type has this flag set. Note that in the case of a 2026-- type the pragma will be chained to the rep item chain of the first 2027-- subtype in the usual manner. 2028 2029-- Has_Xref_Entry (Flag182) 2030-- Defined in all entities. Set if an entity has an entry in the Xref 2031-- information generated in ali files. This is true for all source 2032-- entities in the extended main source file. It is also true of entities 2033-- in other packages that are referenced directly or indirectly from the 2034-- main source file (indirect reference occurs when the main source file 2035-- references an entity with a type reference. See package Lib.Xref for 2036-- further details). 2037 2038-- Hiding_Loop_Variable (Node8) 2039-- Defined in variables. Set only if a variable of a discrete type is 2040-- hidden by a loop variable in the same local scope, in which case 2041-- the Hiding_Loop_Variable field of the hidden variable points to 2042-- the E_Loop_Parameter entity doing the hiding. Used in processing 2043-- warning messages if the hidden variable turns out to be unused 2044-- or is referenced without being set. 2045 2046-- Homonym (Node4) 2047-- Defined in all entities. Link for list of entities that have the 2048-- same source name and that are declared in the same or enclosing 2049-- scopes. Homonyms in the same scope are overloaded. Used for name 2050-- resolution and for the generation of debugging information. 2051 2052-- Implementation_Base_Type (synthesized) 2053-- Applies to all entities. For types, similar to Base_Type, but never 2054-- returns a private type when applied to a non-private type. Instead in 2055-- this case, it always returns the Underlying_Type of the base type, so 2056-- that we still have a concrete type. For entities other than types, 2057-- returns the entity unchanged. 2058 2059-- Import_Pragma (Node35) 2060-- Defined in subprogram entities. Set if a valid pragma Import or pragma 2061-- Import_Function or pragma Import_Procedure applies to the subprogram, 2062-- in which case this field points to the pragma (we can't use the normal 2063-- Rep_Item chain mechanism, because a single pragma Import can apply 2064-- to multiple subprogram entities). 2065 2066-- In_Package_Body (Flag48) 2067-- Defined in package entities. Set on the entity that denotes the 2068-- package (the defining occurrence of the package declaration) while 2069-- analyzing and expanding the package body. Reset on completion of 2070-- analysis/expansion. 2071 2072-- In_Private_Part (Flag45) 2073-- Defined in all entities. Can be set only in package entities and 2074-- objects. For package entities, this flag is set to indicate that the 2075-- private part of the package is being analyzed. The flag is reset at 2076-- the end of the package declaration. For objects it indicates that the 2077-- declaration of the object occurs in the private part of a package. 2078 2079-- Initialization_Statements (Node28) 2080-- Defined in constants and variables. For a composite object initialized 2081-- initialized with an aggregate that has been converted to a sequence 2082-- of assignments, points to a block statement containing the 2083-- assignments. 2084 2085-- Inner_Instances (Elist23) 2086-- Defined in generic units. Contains element list of units that are 2087-- instantiated within the given generic. Used to diagnose circular 2088-- instantiations. 2089 2090-- Interface_Alias (Node25) 2091-- Defined in subprograms that cover a primitive operation of an abstract 2092-- interface type. Can be set only if the Is_Hidden flag is also set, 2093-- since such entities are always hidden. Points to its associated 2094-- interface subprogram. It is used to register the subprogram in 2095-- secondary dispatch table of the interface (Ada 2005: AI-251). 2096 2097-- Interface_Name (Node21) 2098-- Defined in constants, variables, exceptions, functions, procedures, 2099-- packages, components (JGNAT only), discriminants (JGNAT only), and 2100-- access to subprograms (JGNAT only). Set to Empty unless an export, 2101-- import, or interface name pragma has explicitly specified an external 2102-- name, in which case it references an N_String_Literal node for the 2103-- specified external name. Note that if this field is Empty, and 2104-- Is_Imported or Is_Exported is set, then the default interface name 2105-- is the name of the entity, cased in a manner that is appropriate to 2106-- the system in use. Note that Interface_Name is ignored if an address 2107-- clause is present (since it is meaningless in this case). 2108-- 2109-- An additional special case usage of this field is in JGNAT for 2110-- E_Component and E_Discriminant. JGNAT allows these entities to be 2111-- imported by specifying pragma Import within a component's containing 2112-- record definition. This supports interfacing to object fields defined 2113-- within Java classes, and such pragmas are generated by the jvm2ada 2114-- binding generator tool whenever it processes classes with public 2115-- object fields. A pragma Import for a component can define the 2116-- External_Name of the imported Java field (which is generally needed, 2117-- because Java names are case sensitive). 2118 2119-- Interfaces (Elist25) 2120-- Defined in record types and subtypes. List of abstract interfaces 2121-- implemented by a tagged type that are not already implemented by the 2122-- ancestors (Ada 2005: AI-251). 2123 2124-- Invariant_Procedure (synthesized) 2125-- Defined in types and subtypes. Set for private types if one or more 2126-- Invariant, or Invariant'Class, or inherited Invariant'Class aspects 2127-- apply to the type. Points to the entity for a procedure which checks 2128-- the invariant. This invariant procedure takes a single argument of the 2129-- given type, and returns if the invariant holds, or raises exception 2130-- Assertion_Error with an appropriate message if it does not hold. This 2131-- attribute is defined but always empty for private subtypes. This 2132-- attribute is also set for the corresponding full type. 2133-- 2134-- Note: the reason this is marked as a synthesized attribute is that the 2135-- way this is stored is as an element of the Subprograms_For_Type field. 2136 2137-- In_Use (Flag8) 2138-- Defined in packages and types. Set when analyzing a use clause for 2139-- the corresponding entity. Reset at end of corresponding declarative 2140-- part. The flag on a type is also used to determine the visibility of 2141-- the primitive operators of the type. 2142 2143-- Is_Abstract_Subprogram (Flag19) 2144-- Defined in all subprograms and entries. Set for abstract subprograms. 2145-- Always False for enumeration literals and entries. See also 2146-- Requires_Overriding. 2147 2148-- Is_Abstract_Type (Flag146) 2149-- Defined in all types. Set for abstract types. 2150 2151-- Is_Access_Constant (Flag69) 2152-- Defined in access types and subtypes. Indicates that the keyword 2153-- constant was present in the access type definition. 2154 2155-- Is_Access_Protected_Subprogram_Type (synthesized) 2156-- Applies to all types, true for named and anonymous access to 2157-- protected subprograms. 2158 2159-- Is_Access_Type (synthesized) 2160-- Applies to all entities, true for access types and subtypes 2161 2162-- Is_Ada_2005_Only (Flag185) 2163-- Defined in all entities, true if a valid pragma Ada_05 or Ada_2005 2164-- applies to the entity which specifically names the entity, indicating 2165-- that the entity is Ada 2005 only. Note that this flag is not set if 2166-- the entity is part of a unit compiled with the normal no-argument form 2167-- of pragma Ada_05 or Ada_2005. 2168 2169-- Is_Ada_2012_Only (Flag199) 2170-- Defined in all entities, true if a valid pragma Ada_12 or Ada_2012 2171-- applies to the entity which specifically names the entity, indicating 2172-- that the entity is Ada 2012 only. Note that this flag is not set if 2173-- the entity is part of a unit compiled with the normal no-argument form 2174-- of pragma Ada_12 or Ada_2012. 2175 2176-- Is_Aliased (Flag15) 2177-- Defined in all entities. Set for objects and types whose declarations 2178-- carry the keyword aliased, and on record components that have the 2179-- keyword. For Ada 2012, also applies to formal parameters. 2180 2181-- Is_Atomic (Flag85) 2182-- Defined in all type entities, and also in constants, components and 2183-- variables. Set if a pragma Atomic or Shared applies to the entity. 2184-- In the case of private and incomplete types, this flag is set in 2185-- both the partial view and the full view. 2186 2187-- Is_Array_Type (synthesized) 2188-- Applies to all entities, true for array types and subtypes 2189 2190-- Is_Asynchronous (Flag81) 2191-- Defined in all type entities and in procedure entities. Set 2192-- if a pragma Asynchronous applies to the entity. 2193 2194-- Is_Base_Type (synthesized) 2195-- Applies to type and subtype entities. True if entity is a base type 2196 2197-- Is_Bit_Packed_Array (Flag122) [implementation base type only] 2198-- Defined in all entities. This flag is set for a packed array type that 2199-- is bit packed (i.e. the component size is known by the front end and 2200-- is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed is always set 2201-- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be 2202-- set without Is_Bit_Packed_Array for the case of an array having one or 2203-- more index types that are enumeration types with non-standard 2204-- enumeration representations. 2205 2206-- Is_Boolean_Type (synthesized) 2207-- Applies to all entities, true for boolean types and subtypes, 2208-- i.e. Standard.Boolean and all types ultimately derived from it. 2209 2210-- Is_Called (Flag102) 2211-- Defined in subprograms. Returns true if the subprogram is called 2212-- in the unit being compiled or in a unit in the context. Used for 2213-- inlining. 2214 2215-- Is_Character_Type (Flag63) 2216-- Defined in all entities. Set for character types and subtypes, 2217-- i.e. enumeration types that have at least one character literal. 2218 2219-- Is_Checked_Ghost_Entity (Flag277) 2220-- Applies to all entities. Set for abstract states, [generic] packages, 2221-- [generic] subprograms, components, discriminants, formal parameters, 2222-- objects, package bodies, subprogram bodies, and [sub]types subject to 2223-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2224-- subject to Assertion_Policy Ghost => Check. 2225 2226-- Is_Child_Unit (Flag73) 2227-- Defined in all entities. Set only for defining entities of program 2228-- units that are child units (but False for subunits). 2229 2230-- Is_Class_Wide_Type (synthesized) 2231-- Applies to all entities, true for class wide types and subtypes 2232 2233-- Is_Class_Wide_Equivalent_Type (Flag35) 2234-- Defined in record types and subtypes. Set to True, if the type acts 2235-- as a class-wide equivalent type, i.e. the Equivalent_Type field of 2236-- some class-wide subtype entity references this record type. 2237 2238-- Is_Compilation_Unit (Flag149) 2239-- Defined in all entities. Set if the entity is a package or subprogram 2240-- entity for a compilation unit other than a subunit (since we treat 2241-- subunits as part of the same compilation operation as the ultimate 2242-- parent, we do not consider them to be separate units for this flag). 2243 2244-- Is_Completely_Hidden (Flag103) 2245-- Defined in all entities. This flag can be set only for E_Discriminant 2246-- entities. This flag can be set only for girder discriminants of 2247-- untagged types. When set, the entity is a girder discriminant of a 2248-- derived untagged type which is not directly visible in the derived 2249-- type because the derived type or one of its ancestors have renamed the 2250-- discriminants in the root type. Note: there are girder discriminants 2251-- which are not Completely_Hidden (e.g. discriminants of a root type). 2252 2253-- Is_Composite_Type (synthesized) 2254-- Applies to all entities, true for all composite types and 2255-- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but 2256-- not both) is true of any type. 2257 2258-- Is_Concurrent_Record_Type (Flag20) 2259-- Defined in record types and subtypes. Set if the type was created 2260-- by the expander to represent a task or protected type. For every 2261-- concurrent type, such as record type is constructed, and task and 2262-- protected objects are instances of this record type at runtime 2263-- (The backend will replace declarations of the concurrent type using 2264-- the declarations of the corresponding record type). See Exp_Ch9 for 2265-- further details. 2266 2267-- Is_Concurrent_Type (synthesized) 2268-- Applies to all entities, true for task types and subtypes and for 2269-- protected types and subtypes. 2270 2271-- Is_Constant_Object (synthesized) 2272-- Applies to all entities, true for E_Constant, E_Loop_Parameter, and 2273-- E_In_Parameter entities. 2274 2275-- Is_Constrained (Flag12) 2276-- Defined in types or subtypes which may have index, discriminant 2277-- or range constraint (i.e. array types and subtypes, record types 2278-- and subtypes, string types and subtypes, and all numeric types). 2279-- Set if the type or subtype is constrained. 2280 2281-- Is_Constr_Subt_For_U_Nominal (Flag80) 2282-- Defined in all types and subtypes. Set only for the constructed 2283-- subtype of an object whose nominal subtype is unconstrained. Note 2284-- that the constructed subtype itself will be constrained. 2285 2286-- Is_Constr_Subt_For_UN_Aliased (Flag141) 2287-- Defined in all types and subtypes. This flag can be set only if 2288-- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in 2289-- addition the object concerned is aliased. This flag is used by 2290-- the backend to determine whether a template must be constructed. 2291 2292-- Is_Constructor (Flag76) 2293-- Defined in function and procedure entities. Set if a pragma 2294-- CPP_Constructor applies to the subprogram. 2295 2296-- Is_Controlled (Flag42) [base type only] 2297-- Defined in all type entities. Indicates that the type is controlled, 2298-- i.e. is either a descendant of Ada.Finalization.Controlled or of 2299-- Ada.Finalization.Limited_Controlled. 2300 2301-- Is_Controlling_Formal (Flag97) 2302-- Defined in all Formal_Kind entities. Marks the controlling parameters 2303-- of dispatching operations. 2304 2305-- Is_CPP_Class (Flag74) 2306-- Defined in all type entities, set only for tagged types to which a 2307-- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied. 2308 2309-- Is_Decimal_Fixed_Point_Type (synthesized) 2310-- Applies to all type entities, true for decimal fixed point 2311-- types and subtypes. 2312 2313-- Is_Default_Init_Cond_Procedure (Flag132) 2314-- Defined in functions and procedures. Set for a generated procedure 2315-- which verifies the assumption of pragma Default_Initial_Condition. 2316 2317-- Is_Descendent_Of_Address (Flag223) 2318-- Defined in all entities. True if the entity is type System.Address, 2319-- or (recursively) a subtype or derived type of System.Address. 2320 2321-- Is_Discrete_Type (synthesized) 2322-- Applies to all entities, true for all discrete types and subtypes 2323 2324-- Is_Discrete_Or_Fixed_Point_Type (synthesized) 2325-- Applies to all entities, true for all discrete types and subtypes 2326-- and all fixed-point types and subtypes. 2327 2328-- Is_Discrim_SO_Function (Flag176) 2329-- Defined in all entities. Set only in E_Function entities that Layout 2330-- creates to compute discriminant-dependent dynamic size/offset values. 2331 2332-- Is_Discriminant_Check_Function (Flag264) 2333-- Defined in all entities. Set only in E_Function entities for functions 2334-- created to do discriminant checks. 2335 2336-- Is_Discriminal (synthesized) 2337-- Applies to all entities, true for renamings of discriminants. Such 2338-- entities appear as constants or IN parameters. 2339 2340-- Is_Dispatch_Table_Entity (Flag234) 2341-- Applies to all entities. Set to indicate to the backend that this 2342-- entity is associated with a dispatch table. 2343 2344-- Is_Dispatching_Operation (Flag6) 2345-- Defined in all entities. Set for procedures, functions, generic 2346-- procedures, and generic functions if the corresponding operation 2347-- is dispatching. 2348 2349-- Is_Dynamic_Scope (synthesized) 2350-- Applies to all Entities. Returns True if the entity is a dynamic 2351-- scope (i.e. a block, subprogram, task_type, entry 2352-- or extended return statement). 2353 2354-- Is_Elementary_Type (synthesized) 2355-- Applies to all entities, true for all elementary types and 2356-- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but 2357-- not both) is true of any type. 2358 2359-- Is_Eliminated (Flag124) 2360-- Defined in type entities, subprogram entities, and object entities. 2361-- Indicates that the corresponding entity has been eliminated by use 2362-- of pragma Eliminate. Also used to mark subprogram entities whose 2363-- declaration and body are within unreachable code that is removed. 2364 2365-- Is_Enumeration_Type (synthesized) 2366-- Defined in all entities, true for enumeration types and subtypes 2367 2368-- Is_Entry (synthesized) 2369-- Applies to all entities, True only for entry and entry family 2370-- entities and False for all other entity kinds. 2371 2372-- Is_Entry_Formal (Flag52) 2373-- Defined in all entities. Set only for entry formals (which can only 2374-- be in, in-out or out parameters). This flag is used to speed up the 2375-- test for the need to replace references in Exp_Ch2. 2376 2377-- Is_Exported (Flag99) 2378-- Defined in all entities. Set if the entity is exported. For now we 2379-- only allow the export of constants, exceptions, functions, procedures 2380-- and variables, but that may well change later on. Exceptions can only 2381-- be exported in the Java VM implementation of GNAT. 2382 2383-- Is_External_State (synthesized) 2384-- Applies to all entities, true for abstract states that are subject to 2385-- option External. 2386 2387-- Is_Finalizer (synthesized) 2388-- Applies to all entities, true for procedures containing finalization 2389-- code to process local or library level objects. 2390 2391-- Is_First_Subtype (Flag70) 2392-- Defined in all entities. True for first subtypes (RM 3.2.1(6)), 2393-- i.e. the entity in the type declaration that introduced the type. 2394-- This may be the base type itself (e.g. for record declarations and 2395-- enumeration type declarations), or it may be the first subtype of 2396-- an anonymous base type (e.g. for integer type declarations or 2397-- constrained array declarations). 2398 2399-- Is_Fixed_Point_Type (synthesized) 2400-- Applies to all entities, true for decimal and ordinary fixed 2401-- point types and subtypes 2402 2403-- Is_Floating_Point_Type (synthesized) 2404-- Applies to all entities, true for float types and subtypes 2405 2406-- Is_Formal (synthesized) 2407-- Applies to all entities, true for IN, IN OUT and OUT parameters 2408 2409-- Is_Formal_Object (synthesized) 2410-- Applies to all entities, true for generic IN and IN OUT parameters 2411 2412-- Is_Formal_Subprogram (Flag111) 2413-- Defined in all entities. Set for generic formal subprograms. 2414 2415-- Is_For_Access_Subtype (Flag118) 2416-- Defined in E_Private_Subtype and E_Record_Subtype entities. Means the 2417-- sole purpose of the type is to be designated by an Access_Subtype and 2418-- hence should not be expanded into components because the type may not 2419-- have been found or frozen yet. 2420 2421-- Is_Frozen (Flag4) 2422-- Defined in all type and subtype entities. Set if type or subtype has 2423-- been frozen. 2424 2425-- Is_Generic_Actual_Subprogram (Flag274) 2426-- Defined on functions and procedures. Set on the entity of the renaming 2427-- declaration created within an instance for an actual subprogram. 2428-- Used to generate constraint checks on calls to these subprograms, even 2429-- within an instance of a predefined run-time unit, in which checks 2430-- are otherwise suppressed. 2431-- 2432-- The flag is also set on the entity of the expression function created 2433-- within an instance, for a function that has external axiomatization, 2434-- for use in GNATprove mode. 2435 2436-- Is_Generic_Actual_Type (Flag94) 2437-- Defined in all type and subtype entities. Set in the subtype 2438-- declaration that renames the generic formal as a subtype of the 2439-- actual. Guarantees that the subtype is not static within the instance. 2440-- Also used during analysis of an instance, to simplify resolution of 2441-- accidental overloading that occurs when different formal types get the 2442-- same actual. 2443 2444-- Is_Generic_Instance (Flag130) 2445-- Defined in all entities. Set to indicate that the entity is an 2446-- instance of a generic unit, or a formal package (which is an instance 2447-- of the template). 2448 2449-- Is_Generic_Subprogram (synthesized) 2450-- Applies to all entities. Yields True for a generic subprogram 2451-- (generic function, generic subprogram), False for all other entities. 2452 2453-- Is_Generic_Type (Flag13) 2454-- Defined in all entities. Set for types which are generic formal types. 2455-- Such types have an Ekind that corresponds to their classification, so 2456-- the Ekind cannot be used to identify generic formal types. 2457 2458-- Is_Generic_Unit (synthesized) 2459-- Applies to all entities. Yields True for a generic unit (generic 2460-- package, generic function, generic procedure), and False for all 2461-- other entities. 2462 2463-- Is_Hidden (Flag57) 2464-- Defined in all entities. Set for all entities declared in the 2465-- private part or body of a package. Also marks generic formals of a 2466-- formal package declared without a box. For library level entities, 2467-- this flag is set if the entity is not publicly visible. This flag 2468-- is reset when compiling the body of the package where the entity 2469-- is declared, when compiling the private part or body of a public 2470-- child unit, and when compiling a private child unit (see Install_ 2471-- Private_Declaration in sem_ch7). 2472 2473-- Is_Hidden_Non_Overridden_Subpgm (Flag2) 2474-- Defined in all entities. Set for implicitly declared subprograms 2475-- that require overriding or are null procedures, and are hidden by 2476-- a non-fully conformant homograph with the same characteristics 2477-- (Ada RM 8.3 12.3/2). 2478 2479-- Is_Hidden_Open_Scope (Flag171) 2480-- Defined in all entities. Set for a scope that contains the 2481-- instantiation of a child unit, and whose entities are not visible 2482-- during analysis of the instance. 2483 2484-- Is_Ignored_Ghost_Entity (Flag278) 2485-- Applies to all entities. Set for abstract states, [generic] packages, 2486-- [generic] subprograms, components, discriminants, formal parameters, 2487-- objects, package bodies, subprogram bodies, and [sub]types subject to 2488-- pragma Ghost or inherit "ghostness" from an enclosing construct, and 2489-- subject to Assertion_Policy Ghost => Ignore. 2490 2491-- Is_Immediately_Visible (Flag7) 2492-- Defined in all entities. Set if entity is immediately visible, i.e. 2493-- is defined in some currently open scope (RM 8.3(4)). 2494 2495-- Is_Implementation_Defined (Flag254) 2496-- Defined in all entities. Set if a pragma Implementation_Defined is 2497-- applied to the pragma. Used to mark all implementation defined 2498-- identifiers in standard library packages, and to implement the 2499-- restriction No_Implementation_Identifiers. 2500 2501-- Is_Imported (Flag24) 2502-- Defined in all entities. Set if the entity is imported. For now we 2503-- only allow the import of exceptions, functions, procedures, packages. 2504-- and variables. Exceptions, packages and types can only be imported in 2505-- the Java VM implementation. 2506 2507-- Is_Incomplete_Or_Private_Type (synthesized) 2508-- Applies to all entities, true for private and incomplete types 2509 2510-- Is_Incomplete_Type (synthesized) 2511-- Applies to all entities, true for incomplete types and subtypes 2512 2513-- Is_Independent (Flag268) 2514-- Defined in all type entities, and also in constants, components and 2515-- variables. Set if a valid pragma or aspect Independent applies to the 2516-- entity, or if a valid pragma or aspect Independent_Components applies 2517-- to the enclosing record type for a component. Also set if a pragma 2518-- Shared or pragma Atomic applies to the entity. In the case of private 2519-- and incomplete types, this flag is set in both the partial view and 2520-- the full view. 2521 2522-- Is_Inlined (Flag11) 2523-- Defined in all entities. Set for functions and procedures which are 2524-- to be inlined. For subprograms created during expansion, this flag 2525-- may be set directly by the expander to request inlining. Also set 2526-- for packages that contain inlined subprograms, whose bodies must be 2527-- be compiled. Is_Inlined is also set on generic subprograms and is 2528-- inherited by their instances. It is also set on the body entities 2529-- of inlined subprograms. See also Has_Pragma_Inline. 2530 2531-- Is_Inlined_Always (Flag1) 2532-- Defined in subprograms. Set for functions and procedures which are 2533-- always inlined in GNATprove mode. GNATprove uses this flag to know 2534-- when a body does not need to be analyzed. The value of this flag is 2535-- only meaningful if Body_To_Inline is not Empty for the subprogram. 2536 2537-- Is_Instantiated (Flag126) 2538-- Defined in generic packages and generic subprograms. Set if the unit 2539-- is instantiated from somewhere in the extended main source unit. This 2540-- flag is used to control warnings about the unit being uninstantiated. 2541-- Also set in a package that is used as an actual for a generic package 2542-- formal in an instantiation. Also set on a parent instance, in the 2543-- instantiation of a child, which is implicitly declared in the parent. 2544 2545-- Is_Integer_Type (synthesized) 2546-- Applies to all entities, true for integer types and subtypes 2547 2548-- Is_Interface (Flag186) 2549-- Defined in record types and subtypes. Set to indicate that the current 2550-- entity corresponds with an abstract interface. Because abstract 2551-- interfaces are conceptually a special kind of abstract tagged types 2552-- we represent them by means of tagged record types and subtypes 2553-- marked with this attribute. This allows us to reuse most of the 2554-- compiler support for abstract tagged types to implement interfaces 2555-- (Ada 2005: AI-251). 2556 2557-- Is_Internal (Flag17) 2558-- Defined in all entities. Set to indicate an entity created during 2559-- semantic processing (e.g. an implicit type, or a temporary). The 2560-- current uses of this flag are: 2561-- 2562-- 1) Internal entities (such as temporaries generated for the result 2563-- of an inlined function call or dummy variables generated for the 2564-- debugger). Set to indicate that they need not be initialized, even 2565-- when scalars are initialized or normalized; 2566-- 2567-- 2) Predefined primitives of tagged types. Set to mark that they 2568-- have specific properties: first they are primitives even if they 2569-- are not defined in the type scope (the freezing point is not 2570-- necessarily in the same scope), and second the predefined equality 2571-- can be overridden by a user-defined equality, no body will be 2572-- generated in this case. 2573-- 2574-- 3) Object declarations generated by the expander that are implicitly 2575-- imported or exported so that they can be marked in Sprint output. 2576-- 2577-- 4) Internal entities in the list of primitives of tagged types that 2578-- are used to handle secondary dispatch tables. These entities have 2579-- also the attribute Interface_Alias. 2580 2581-- Is_Interrupt_Handler (Flag89) 2582-- Defined in procedures. Set if a pragma Interrupt_Handler applies 2583-- to the procedure. The procedure must be parameterless, and on all 2584-- targets except AAMP it must be a protected procedure. 2585 2586-- Is_Intrinsic_Subprogram (Flag64) 2587-- Defined in functions and procedures. It is set if a valid pragma 2588-- Interface or Import is present for this subprogram specifying pragma 2589-- Intrinsic. Valid means that the name and profile of the subprogram 2590-- match the requirements of one of the recognized intrinsic subprograms 2591-- (see package Sem_Intr for details). Note: the value of Convention for 2592-- such an entity will be set to Convention_Intrinsic, but it is the 2593-- setting of Is_Intrinsic_Subprogram, NOT simply having convention set 2594-- to intrinsic, which causes intrinsic code to be generated. 2595 2596-- Is_Invariant_Procedure (Flag257) 2597-- Defined in functions an procedures. Set for a generated invariant 2598-- procedure to identify it easily in the 2599 2600-- Is_Itype (Flag91) 2601-- Defined in all entities. Set to indicate that a type is an Itype, 2602-- which means that the declaration for the type does not appear 2603-- explicitly in the tree. Instead the backend will elaborate the type 2604-- when it is first used. Has_Delayed_Freeze can be set for Itypes, and 2605-- the meaning is that the first use (the one which causes the type to be 2606-- defined) will be the freeze node. Note that an important restriction 2607-- on Itypes is that the first use of such a type (the one that causes it 2608-- to be defined) must be in the same scope as the type. 2609 2610-- Is_Known_Non_Null (Flag37) 2611-- Defined in all entities. Relevant (and can be set) only for 2612-- objects of an access type. It is set if the object is currently 2613-- known to have a non-null value (meaning that no access checks 2614-- are needed). The indication can for example come from assignment 2615-- of an access parameter or an allocator whose value is known non-null. 2616-- 2617-- Note: this flag is set according to the sequential flow of the 2618-- program, watching the current value of the variable. However, this 2619-- processing can miss cases of changing the value of an aliased or 2620-- constant object, so even if this flag is set, it should not be 2621-- believed if the variable is aliased or volatile. It would be a 2622-- little neater to avoid the flag being set in the first place in 2623-- such cases, but that's trickier, and there is only one place that 2624-- tests the value anyway. 2625-- 2626-- The flag is dynamically set and reset as semantic analysis and 2627-- expansion proceeds. Its value is meaningless once the tree is 2628-- fully constructed, since it simply indicates the last state. 2629-- Thus this flag has no meaning to the backend. 2630 2631-- Is_Known_Null (Flag204) 2632-- Defined in all entities. Relevant (and can be set ) only for 2633-- objects of an access type. It is set if the object is currently known 2634-- to have a null value (meaning that a dereference will surely raise 2635-- constraint error exception). The indication can come from an 2636-- assignment or object declaration. 2637-- 2638-- The comments above about sequential flow and aliased and volatile for 2639-- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag. 2640 2641-- Is_Known_Valid (Flag170) 2642-- Defined in all entities. Relevant for types (and subtype) and 2643-- for objects (and enumeration literals) of a discrete type. 2644-- 2645-- The purpose of this flag is to implement the requirement stated 2646-- in (RM 13.9.1(9-11)) which require that the use of possibly invalid 2647-- values may not cause programs to become erroneous. See the function 2648-- Checks.Expr_Known_Valid for further details. Note that the setting 2649-- is conservative, in the sense that if the flag is set, it must be 2650-- right. If the flag is not set, nothing is known about the validity. 2651-- 2652-- For enumeration literals, the flag is always set, since clearly 2653-- an enumeration literal represents a valid value. Range checks 2654-- where necessary will ensure that this valid value is appropriate. 2655-- 2656-- For objects, the flag indicates the state of knowledge about the 2657-- current value of the object. This may be modified during expansion, 2658-- and thus the final value is not relevant to the backend. 2659-- 2660-- For types and subtypes, the flag is set if all possible bit patterns 2661-- of length Object_Size (i.e. Esize of the type) represent valid values 2662-- of the type. In general for such tytpes, all values are valid, the 2663-- only exception being the case where an object of the type has an 2664-- explicit size that is greater than Object_Size. 2665-- 2666-- For non-discrete objects, the setting of the Is_Known_Valid flag is 2667-- not defined, and is not relevant, since the considerations of the 2668-- requirement in (RM 13.9.1(9-11)) do not apply. 2669-- 2670-- The flag is dynamically set and reset as semantic analysis and 2671-- expansion proceeds. Its value is meaningless once the tree is 2672-- fully constructed, since it simply indicates the last state. 2673-- Thus this flag has no meaning to the backend. 2674 2675-- Is_Limited_Composite (Flag106) 2676-- Defined in all entities. Set for composite types that have a limited 2677-- component. Used to enforce the rule that operations on the composite 2678-- type that depend on the full view of the component do not become 2679-- visible until the immediate scope of the composite type itself 2680-- (RM 7.3.1 (5)). 2681 2682-- Is_Limited_Interface (Flag197) 2683-- Defined in record types and subtypes. True for interface types, if 2684-- interface is declared limited, task, protected, or synchronized, or 2685-- is derived from a limited interface. 2686 2687-- Is_Limited_Record (Flag25) 2688-- Defined in all entities. Set to true for record (sub)types if the 2689-- record is declared to be limited. Note that this flag is not set 2690-- simply because some components of the record are limited. 2691 2692-- Is_Local_Anonymous_Access (Flag194) 2693-- Defined in access types. Set for an anonymous access type to indicate 2694-- that the type is created for a record component with an access 2695-- definition, an array component, or (pre-Ada 2012) a standalone object. 2696-- Such anonymous types have an accessibility level equal to that of the 2697-- declaration in which they appear, unlike the anonymous access types 2698-- that are created for access parameters, access discriminants, and 2699-- (as of Ada 2012) stand-alone objects. 2700 2701-- Is_Machine_Code_Subprogram (Flag137) 2702-- Defined in subprogram entities. Set to indicate that the subprogram 2703-- is a machine code subprogram (i.e. its body includes at least one 2704-- code statement). Also indicates that all necessary semantic checks 2705-- as required by RM 13.8(3) have been performed. 2706 2707-- Is_Modular_Integer_Type (synthesized) 2708-- Applies to all entities. True if entity is a modular integer type 2709 2710-- Is_Non_Static_Subtype (Flag109) 2711-- Defined in all type and subtype entities. It is set in some (but not 2712-- all) cases in which a subtype is known to be non-static. Before this 2713-- flag was added, the computation of whether a subtype was static was 2714-- entirely synthesized, by looking at the bounds, and the immediate 2715-- subtype parent. However, this method does not work for some Itypes 2716-- that have no parent set (and the only way to find the immediate 2717-- subtype parent is to go through the tree). For now, this flag is set 2718-- conservatively, i.e. if it is set then for sure the subtype is non- 2719-- static, but if it is not set, then the type may or may not be static. 2720-- Thus the test for a static subtype is that this flag is clear AND that 2721-- the bounds are static AND that the parent subtype (if available to be 2722-- tested) is static. Eventually we should make sure this flag is always 2723-- set right, at which point, these comments can be removed, and the 2724-- tests for static subtypes greatly simplified. 2725 2726-- Is_Null_Init_Proc (Flag178) 2727-- Defined in procedure entities. Set for generated init proc procedures 2728-- (used to initialize composite types), if the code for the procedure 2729-- is null (i.e. is a return and nothing else). Such null initialization 2730-- procedures are generated in case some client is compiled using the 2731-- Initialize_Scalars pragma, generating a call to this null procedure, 2732-- but there is no need to call such procedures within a compilation 2733-- unit, and this flag is used to suppress such calls. 2734 2735-- Is_Null_State (synthesized) 2736-- Applies to all entities, true for an abstract state declared with 2737-- keyword null. 2738 2739-- Is_Numeric_Type (synthesized) 2740-- Applies to all entities, true for all numeric types and subtypes 2741-- (integer, fixed, float). 2742 2743-- Is_Object (synthesized) 2744-- Applies to all entities, true for entities representing objects, 2745-- including generic formal parameters. 2746 2747-- Is_Obsolescent (Flag153) 2748-- Defined in all entities. Set for any entity to which a valid pragma 2749-- or aspect Obsolescent applies. 2750 2751-- Is_Only_Out_Parameter (Flag226) 2752-- Defined in formal parameter entities. Set if this parameter is the 2753-- only OUT parameter for this formal part. If there is more than one 2754-- out parameter, or if there is some other IN OUT parameter then this 2755-- flag is not set in any of them. Used in generation of warnings. 2756 2757-- Is_Ordinary_Fixed_Point_Type (synthesized) 2758-- Applies to all entities, true for ordinary fixed point types and 2759-- subtypes. 2760 2761-- Is_Package_Or_Generic_Package (synthesized) 2762-- Applies to all entities. True for packages and generic packages. 2763-- False for all other entities. 2764 2765-- Is_Package_Body_Entity (Flag160) 2766-- Defined in all entities. Set for entities defined at the top level 2767-- of a package body. Used to control externally generated names. 2768 2769-- Is_Packed (Flag51) [implementation base type only] 2770-- Defined in all type entities. This flag is set only for record and 2771-- array types which have a packed representation. There are three 2772-- cases which cause packing: 2773-- 2774-- 1. Explicit use of pragma Pack for an array of package components 2775-- 2. Explicit use of pragma Pack to pack a record 2776-- 4. Setting Component_Size of an array to a bit-packable value 2777-- 3. Indexing an array with a non-standard enumeration type. 2778-- 2779-- For records, Is_Packed is always set if Has_Pragma_Pack is set, 2780-- and can also be set on its own in a derived type which inherited 2781-- its packed status. 2782-- 2783-- For arrays, Is_Packed is set if an array is bit packed (i.e. the 2784-- component size is known at compile time and is 1-7, 9-15 or 17-31), 2785-- or if the array has one or more index types that are enumeration 2786-- types with non-standard representations (in GNAT, we store such 2787-- arrays compactly, using the Pos of the enumeration type value). 2788-- 2789-- As for the case of records, Is_Packed can be set on its own for a 2790-- derived type, with the same dual before/after freeze meaning. 2791-- Is_Packed can also be set as the result of an explicit component 2792-- size clause that specifies an appropriate component size. 2793-- 2794-- In the bit packed array case, Is_Bit_Packed_Array will be set in 2795-- the bit packed case once the array type is frozen. 2796-- 2797-- Before an array type is frozen, Is_Packed will always be set if 2798-- Has_Pragma_Pack is set. Before the freeze point, it is not possible 2799-- to know the component size, since the component type is not frozen 2800-- until the array type is frozen. Thus Is_Packed for an array type 2801-- before it is frozen means that packed is required. Then if it turns 2802-- out that the component size is not suitable for bit packing, the 2803-- Is_Packed flag gets turned off. 2804 2805-- Is_Packed_Array (synth) 2806-- Applies to all entities, true if entity is for a packed array. 2807 2808-- Is_Packed_Array_Impl_Type (Flag138) 2809-- Defined in all entities. This flag is set on the entity for the type 2810-- used to implement a packed array (either a modular type, or a subtype 2811-- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only 2812-- if the type appears in the Packed_Array_Impl_Type field of some other 2813-- entity. It is used by the backend to activate the special processing 2814-- for such types (unchecked conversions that would not otherwise be 2815-- allowed are allowed for such types). If Is_Packed_Array_Impl_Type is 2816-- set in an entity, then the Original_Array_Type field of this entity 2817-- points to the array type for which this is the Packed_Array_Impl_Type. 2818 2819-- Is_Potentially_Use_Visible (Flag9) 2820-- Defined in all entities. Set if entity is potentially use visible, 2821-- i.e. it is defined in a package that appears in a currently active 2822-- use clause (RM 8.4(8)). Note that potentially use visible entities 2823-- are not necessarily use visible (RM 8.4(9-11)). 2824 2825-- Is_Predicate_Function (Flag255) 2826-- Present in functions and procedures. Set for generated predicate 2827-- functions. 2828 2829-- Is_Predicate_Function_M (Flag256) 2830-- Present in functions and procedures. Set for special version of 2831-- predicate function generated for use in membership tests, where 2832-- raise expressions are transformed to return False. 2833 2834-- Is_Preelaborated (Flag59) 2835-- Defined in all entities, set in E_Package and E_Generic_Package 2836-- entities to which a pragma Preelaborate is applied, and also in 2837-- all entities within such packages. Note that the fact that this 2838-- flag is set does not necesarily mean that no elaboration code is 2839-- generated for the package. 2840 2841-- Is_Primitive (Flag218) 2842-- Defined in overloadable entities and in generic subprograms. Set to 2843-- indicate that this is a primitive operation of some type, which may 2844-- be a tagged type or an untagged type. Used to verify overriding 2845-- indicators in bodies. 2846 2847-- Is_Primitive_Wrapper (Flag195) 2848-- Defined in functions and procedures created by the expander to serve 2849-- as an indirection mechanism to overriding primitives of concurrent 2850-- types, entries and protected procedures. 2851 2852-- Is_Prival (synthesized) 2853-- Applies to all entities, true for renamings of private protected 2854-- components. Such entities appear as constants or variables. 2855 2856-- Is_Private_Composite (Flag107) 2857-- Defined in composite types that have a private component. Used to 2858-- enforce the rule that operations on the composite type that depend 2859-- on the full view of the component, do not become visible until the 2860-- immediate scope of the composite type itself (7.3.1 (5)). Both this 2861-- flag and Is_Limited_Composite are needed. 2862 2863-- Is_Private_Descendant (Flag53) 2864-- Defined in entities that can represent library units (packages, 2865-- functions, procedures). Set if the library unit is itself a private 2866-- child unit, or if it is the descendent of a private child unit. 2867 2868-- Is_Private_Primitive (Flag245) 2869-- Defined in subprograms. Set if the operation is a primitive of a 2870-- tagged type (procedure or function dispatching on result) whose 2871-- full view has not been seen. Used in particular for primitive 2872-- subprograms of a synchronized type declared between the two views 2873-- of the type, so that the wrapper built for such a subprogram can 2874-- be given the proper signature. 2875 2876-- Is_Private_Type (synthesized) 2877-- Applies to all entities, true for private types and subtypes, 2878-- as well as for record with private types as subtypes 2879 2880-- Is_Processed_Transient (Flag252) 2881-- Defined in variables, loop parameters, and constants, including the 2882-- loop parameters of generalized iterators. Set when a transient object 2883-- needs to be finalized and has already been processed by the transient 2884-- scope machinery. This flag signals the general finalization mechanism 2885-- to ignore the transient object. 2886 2887-- Is_Protected_Component (synthesized) 2888-- Applicable to all entities, true if the entity denotes a private 2889-- component of a protected type. 2890 2891-- Is_Protected_Interface (synthesized) 2892-- Defined in types that are interfaces. True if interface is declared 2893-- protected, or is derived from protected interfaces. 2894 2895-- Is_Protected_Type (synthesized) 2896-- Applies to all entities, true for protected types and subtypes 2897 2898-- Is_Public (Flag10) 2899-- Defined in all entities. Set to indicate that an entity defined in 2900-- one compilation unit can be referenced from other compilation units. 2901-- If this reference causes a reference in the generated code, for 2902-- example in the case of a variable name, then the backend will generate 2903-- an appropriate external name for use by the linker. 2904 2905-- Is_Protected_Record_Type (synthesized) 2906-- Applies to all entities, true if Is_Concurrent_Record_Type is true and 2907-- Corresponding_Concurrent_Type is a protected type. 2908 2909-- Is_Pure (Flag44) 2910-- Defined in all entities. Set in all entities of a unit to which a 2911-- pragma Pure is applied except for non-intrinsic imported subprograms, 2912-- and also set for the entity of the unit itself. In addition, this 2913-- flag may be set for any other functions or procedures that are known 2914-- to be side effect free, so in the case of subprograms, the Is_Pure 2915-- flag may be used by the optimizer to imply that it can assume freedom 2916-- from side effects (other than those resulting from assignment to out 2917-- parameters, or to objects designated by access parameters). 2918 2919-- Is_Pure_Unit_Access_Type (Flag189) 2920-- Defined in access type and subtype entities. Set if the type or 2921-- subtype appears in a pure unit. Used to give an error message at 2922-- freeze time if the access type has a storage pool. 2923 2924-- Is_RACW_Stub_Type (Flag244) 2925-- Defined in all types, true for the stub types generated for remote 2926-- access-to-class-wide types. 2927 2928-- Is_Raised (Flag224) 2929-- Defined in exception entities. Set if the entity is referenced by a 2930-- a raise statement. 2931 2932-- Is_Real_Type (synthesized) 2933-- Applies to all entities, true for real types and subtypes 2934 2935-- Is_Record_Type (synthesized) 2936-- Applies to all entities, true for record types and subtypes, 2937-- includes class-wide types and subtypes (which are also records) 2938 2939-- Is_Remote_Call_Interface (Flag62) 2940-- Defined in all entities. Set in E_Package and E_Generic_Package 2941-- entities to which a pragma Remote_Call_Interface is applied, and 2942-- also on entities declared in the visible part of such a package. 2943 2944-- Is_Remote_Types (Flag61) 2945-- Defined in all entities. Set in E_Package and E_Generic_Package 2946-- entities to which a pragma Remote_Types is applied, and also on 2947-- entities declared in the visible part of the spec of such a package. 2948-- Also set for types which are generic formal types to which the 2949-- pragma Remote_Access_Type applies. 2950 2951-- Is_Renaming_Of_Object (Flag112) 2952-- Defined in all entities, set only for a variable or constant for 2953-- which the Renamed_Object field is non-empty and for which the 2954-- renaming is handled by the front end, by macro substitution of 2955-- a copy of the (evaluated) name tree whereever the variable is used. 2956 2957-- Is_Return_Object (Flag209) 2958-- Defined in all object entities. True if the object is the return 2959-- object of an extended_return_statement; False otherwise. 2960 2961-- Is_Safe_To_Reevaluate (Flag249) 2962-- Defined in all entities. Set in variables that are initialized by 2963-- means of an assignment statement. When initialized their contents 2964-- never change and hence they can be seen by the backend as constants. 2965-- See also Is_True_Constant. 2966 2967-- Is_Scalar_Type (synthesized) 2968-- Applies to all entities, true for scalar types and subtypes 2969 2970-- Is_Shared_Passive (Flag60) 2971-- Defined in all entities. Set in E_Package and E_Generic_Package 2972-- entities to which a pragma Shared_Passive is applied, and also in 2973-- all entities within such packages. 2974 2975-- Is_Standard_Character_Type (synthesized) 2976-- Applies to all entities, true for types and subtypes whose root type 2977-- is one of the standard character types (Character, Wide_Character, or 2978-- Wide_Wide_Character). 2979 2980-- Is_Standard_String_Type (synthesized) 2981-- Applies to all entities, true for types and subtypes whose root 2982-- type is one of the standard string types (String, Wide_String, or 2983-- Wide_Wide_String). 2984 2985-- Is_Static_Type (Flag281) 2986-- Defined in all type and subtype entities. If set, indicates that the 2987-- type is known to be a static type (defined as a discrete type with 2988-- static bounds, a record all of whose component types are static types, 2989-- or an array, all of whose bounds are of a static type, and also have 2990-- a component type that is a static type). See Set_Uplevel_Type for more 2991-- information on how this flag is used. Note that if Is_Static_Type is 2992-- True, then it is never the case that the Has_Uplevel_Reference flag is 2993-- set for the same type. 2994 2995-- Is_Statically_Allocated (Flag28) 2996-- Defined in all entities. This can only be set for exception, 2997-- variable, constant, and type/subtype entities. If the flag is set, 2998-- then the variable or constant must be allocated statically rather 2999-- than on the local stack frame. For exceptions, the meaning is that 3000-- the exception data should be allocated statically (and indeed this 3001-- flag is always set for exceptions, since exceptions do not have 3002-- local scope). For a type, the meaning is that the type must be 3003-- elaborated at the global level rather than locally. No type marked 3004-- with this flag may depend on a local variable, or on any other type 3005-- which does not also have this flag set to True. For a variable or 3006-- or constant, if the flag is set, then the type of the object must 3007-- either be declared at the library level, or it must also have the 3008-- flag set (since to allocate the object statically, its type must 3009-- also be elaborated globally). 3010 3011-- Is_String_Type (synthesized) 3012-- Applies to all type entities. Determines if the given type is a 3013-- string type, i.e. it is directly a string type or string subtype, 3014-- or a string slice type, or an array type with one dimension and a 3015-- component type that is a character type. 3016 3017-- Is_Subprogram (synthesized) 3018-- Applies to all entities, true for function, procedure and operator 3019-- entities. 3020 3021-- Is_Subprogram_Or_Generic_Subprogram 3022-- Applies to all entities, true for function procedure and operator 3023-- entities, and also for the corresponding generic entities. 3024 3025-- Is_Synchronized_Interface (synthesized) 3026-- Defined in types that are interfaces. True if interface is declared 3027-- synchronized, task, or protected, or is derived from a synchronized 3028-- interface. 3029 3030-- Is_Tag (Flag78) 3031-- Defined in E_Component and E_Constant entities. For regular tagged 3032-- type this flag is set on the tag component (whose name is Name_uTag). 3033-- For CPP_Class tagged types, this flag marks the pointer to the main 3034-- vtable (i.e. the one to be extended by derivation). 3035 3036-- Is_Tagged_Type (Flag55) 3037-- Defined in all entities. Set for an entity that is a tagged type. 3038 3039-- Is_Task_Interface (synthesized) 3040-- Defined in types that are interfaces. True if interface is declared as 3041-- a task interface, or if it is derived from task interfaces. 3042 3043-- Is_Task_Record_Type (synthesized) 3044-- Applies to all entities. True if Is_Concurrent_Record_Type 3045-- Corresponding_Concurrent_Type is a task type. 3046 3047-- Is_Task_Type (synthesized) 3048-- Applies to all entities. True for task types and subtypes 3049 3050-- Is_Thunk (Flag225) 3051-- Defined in all entities. True for subprograms that are thunks: that is 3052-- small subprograms built by the expander for tagged types that cover 3053-- interface types. As part of the runtime call to an interface, thunks 3054-- displace the pointer to the object (pointer named "this" in the C++ 3055-- terminology) from a secondary dispatch table to the primary dispatch 3056-- table associated with a given tagged type; if the thunk is a function 3057-- that returns an object which covers an interface type then the thunk 3058-- displaces the pointer to the object from the primary dispatch table to 3059-- the secondary dispatch table associated with the interface type. Set 3060-- by Expand_Interface_Thunk and used by Expand_Call to handle extra 3061-- actuals associated with accessibility level. 3062 3063-- Is_Trivial_Subprogram (Flag235) 3064-- Defined in all entities. Set in subprograms where either the body 3065-- consists of a single null statement, or the first or only statement 3066-- of the body raises an exception. This is used for suppressing certain 3067-- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details. 3068 3069-- Is_True_Constant (Flag163) 3070-- Defined in all entities for constants and variables. Set in constants 3071-- and variables which have an initial value specified but which are 3072-- never assigned, partially or in the whole. For variables, it means 3073-- that the variable was initialized but never modified, and hence can be 3074-- treated as a constant by the code generator. For a constant, it means 3075-- that the constant was not modified by generated code (e.g. to set a 3076-- discriminant in an init proc). Assignments by user or generated code 3077-- will reset this flag. See also Is_Safe_To_Reevaluate. 3078 3079-- Is_Type (synthesized) 3080-- Applies to all entities, true for a type entity 3081 3082-- Is_Unchecked_Union (Flag117) [implementation base type only] 3083-- Defined in all entities. Set only in record types to which the 3084-- pragma Unchecked_Union has been validly applied. 3085 3086-- Is_Underlying_Record_View (Flag246) [base type only] 3087-- Defined in all entities. Set only in record types that represent the 3088-- underlying record view. This view is built for derivations of types 3089-- with unknown discriminants; it is a record with the same structure 3090-- as its corresponding record type, but whose parent is the full view 3091-- of the parent in the original type extension. 3092 3093-- Is_Unimplemented (Flag284) 3094-- Defined in all entities. Set for any entity to which a valid pragma 3095-- or aspect Unimplemented applies. 3096 3097-- Is_Unsigned_Type (Flag144) 3098-- Defined in all types, but can be set only for discrete and fixed-point 3099-- type and subtype entities. This flag is only valid if the entity is 3100-- frozen. If set it indicates that the representation is known to be 3101-- unsigned (i.e. that no negative values appear in the range). This is 3102-- normally just a reflection of the lower bound of the subtype or base 3103-- type, but there is one case in which the setting is non-obvious, 3104-- namely the case of an unsigned subtype of a signed type from which 3105-- a further subtype is obtained using variable bounds. This further 3106-- subtype is still unsigned, but this cannot be determined by looking 3107-- at its bounds or the bounds of the corresponding base type. 3108 3109-- Is_Valued_Procedure (Flag127) 3110-- Defined in procedure entities. Set if an Import_Valued_Procedure 3111-- or Export_Valued_Procedure pragma applies to the procedure entity. 3112 3113-- Is_Visible_Formal (Flag206) 3114-- Defined in all entities. Set for instances of the formals of a 3115-- formal package. Indicates that the entity must be made visible in the 3116-- body of the instance, to reproduce the visibility of the generic. 3117-- This simplifies visibility settings in instance bodies. 3118 3119-- Is_Visible_Lib_Unit (Flag116) 3120-- Defined in all (root or child) library unit entities. Once compiled, 3121-- library units remain chained to the entities in the parent scope, and 3122-- a separate flag must be used to indicate whether the names are visible 3123-- by selected notation, or not. 3124 3125-- Is_Volatile (Flag16) 3126-- Defined in all type entities, and also in constants, components and 3127-- variables. Set if a pragma Volatile applies to the entity. Also set 3128-- if pragma Shared or pragma Atomic applies to entity. In the case of 3129-- private or incomplete types, this flag is set in both the private 3130-- and full view. The flag is not set reliably on private subtypes, 3131-- and is always retrieved from the base type (but this is not a base- 3132-- type-only attribute because it applies to other entities). Note that 3133-- the backend should use Treat_As_Volatile, rather than Is_Volatile 3134-- to indicate code generation requirements for volatile variables. 3135-- Similarly, any front end test which is concerned with suppressing 3136-- optimizations on volatile objects should test Treat_As_Volatile 3137-- rather than testing this flag. 3138 3139-- Is_Wrapper_Package (synthesized) 3140-- Defined in package entities. Indicates that the package has been 3141-- created as a wrapper for a subprogram instantiation. 3142 3143-- Itype_Printed (Flag202) 3144-- Defined in all type and subtype entities. Set in Itypes if the Itype 3145-- has been printed by Sprint. This is used to avoid printing an Itype 3146-- more than once. 3147 3148-- Kill_Elaboration_Checks (Flag32) 3149-- Defined in all entities. Set by the expander to kill elaboration 3150-- checks which are known not to be needed. Equivalent in effect to 3151-- the use of pragma Suppress (Elaboration_Checks) for that entity 3152-- except that the effect is permanent and cannot be undone by a 3153-- subsequent pragma Unsuppress. 3154 3155-- Kill_Range_Checks (Flag33) 3156-- Defined in all entities. Equivalent in effect to the use of pragma 3157-- Suppress (Range_Checks) for that entity except that the result is 3158-- permanent and cannot be undone by a subsequent pragma Unsuppress. 3159-- This is currently only used in one odd situation in Sem_Ch3 for 3160-- record types, and it would be good to get rid of it??? 3161 3162-- Known_To_Have_Preelab_Init (Flag207) 3163-- Defined in all type and subtype entities. If set, then the type is 3164-- known to have preelaborable initialization. In the case of a partial 3165-- view of a private type, it is only possible for this to be set if a 3166-- pragma Preelaborable_Initialization is given for the type. For other 3167-- types, it is never set if the type does not have preelaborable 3168-- initialization, it may or may not be set if the type does have 3169-- preelaborable initialization. 3170 3171-- Last_Aggregate_Assignment (Node30) 3172-- Applies to controlled constants and variables initialized by an 3173-- aggregate. Points to the last statement associated with the expansion 3174-- of the aggregate. The attribute is used by the finalization machinery 3175-- when marking an object as successfully initialized. 3176 3177-- Last_Assignment (Node26) 3178-- Defined in entities for variables, and OUT or IN OUT formals. Set for 3179-- a local variable or formal to point to the left side of an assignment 3180-- statement assigning a value to the variable. Cleared if the value of 3181-- the entity is referenced. Used to warn about dubious assignment 3182-- statements whose value is not used. 3183 3184-- Last_Entity (Node20) 3185-- Defined in all entities which act as scopes to which a list of 3186-- associated entities is attached (blocks, class subtypes and types, 3187-- entries, functions, loops, packages, procedures, protected objects, 3188-- record types and subtypes, private types, task types and subtypes). 3189-- Points to the last entry in the list of associated entities chained 3190-- through the Next_Entity field. Empty if no entities are chained. 3191 3192-- Last_Formal (synthesized) 3193-- Applies to subprograms and subprogram types, and also in entries 3194-- and entry families. Returns last formal of the subprogram or entry. 3195-- The formals are the first entities declared in a subprogram or in 3196-- a subprogram type (the designated type of an Access_To_Subprogram 3197-- definition) or in an entry. 3198 3199-- Limited_View (Node23) 3200-- Defined in non-generic package entities that are not instances. Bona 3201-- fide package with the limited-view list through the first_entity and 3202-- first_private attributes. The elements of this list are the shadow 3203-- entities created for the types and local packages that are declared 3204-- in a package appearing in a limited_with clause (Ada 2005: AI-50217). 3205 3206-- Linker_Section_Pragma (Node33) 3207-- Present in constant, variable, type and subprogram entities. Points 3208-- to a linker section pragma that applies to the entity, or is Empty if 3209-- no such pragma applies. Note that for constants and variables, this 3210-- field may be set as a result of a linker section pragma applied to the 3211-- type of the object. 3212 3213-- Lit_Indexes (Node18) 3214-- Defined in enumeration types and subtypes. Non-empty only for the 3215-- case of an enumeration root type, where it contains the entity for 3216-- the generated indexes entity. See unit Exp_Imgv for full details of 3217-- the nature and use of this entity for implementing the Image and 3218-- Value attributes for the enumeration type in question. 3219 3220-- Lit_Strings (Node16) 3221-- Defined in enumeration types and subtypes. Non-empty only for the 3222-- case of an enumeration root type, where it contains the entity for 3223-- the literals string entity. See unit Exp_Imgv for full details of 3224-- the nature and use of this entity for implementing the Image and 3225-- Value attributes for the enumeration type in question. 3226 3227-- Low_Bound_Tested (Flag205) 3228-- Defined in all entities. Currently this can only be set for formal 3229-- parameter entries of a standard unconstrained one-dimensional array 3230-- or string type. Indicates that an explicit test of the low bound of 3231-- the formal appeared in the code, e.g. in a pragma Assert. If this 3232-- flag is set, warnings about assuming the index low bound to be one 3233-- are suppressed. 3234 3235-- Machine_Radix_10 (Flag84) 3236-- Defined in decimal types and subtypes, set if the Machine_Radix is 10, 3237-- as the result of the specification of a machine radix representation 3238-- clause. Note that it is possible for this flag to be set without 3239-- having Has_Machine_Radix_Clause True. This happens when a type is 3240-- derived from a type with a clause present. 3241 3242-- Master_Id (Node17) 3243-- Defined in access types and subtypes. Empty unless Has_Task is set for 3244-- the designated type, in which case it points to the entity for the 3245-- Master_Id for the access type master. Also set for access-to-limited- 3246-- class-wide types whose root may be extended with task components, and 3247-- for access-to-limited-interfaces because they can be used to reference 3248-- tasks implementing such interface. 3249 3250-- Materialize_Entity (Flag168) 3251-- Defined in all entities. Set only for renamed obects which should be 3252-- materialized for debugging purposes. This means that a memory location 3253-- containing the renamed address should be allocated. This is needed so 3254-- that the debugger can find the entity. 3255 3256-- May_Inherit_Delayed_Rep_Aspects (Flag262) 3257-- Defined in all entities for types and subtypes. Set if the type is 3258-- derived from a type which has delayed rep aspects (marked by the flag 3259-- Has_Delayed_Rep_Aspects being set). In this case, at the freeze point 3260-- for the derived type we know that the parent type is frozen, and if 3261-- a given attribute has not been set for the derived type, we copy the 3262-- value from the parent type. See Freeze.Inherit_Delayed_Rep_Aspects. 3263 3264-- Mechanism (Uint8) (returned as Mechanism_Type) 3265-- Defined in functions and non-generic formal parameters. Indicates 3266-- the mechanism to be used for the function return or for the formal 3267-- parameter. See full description in the spec of Sem_Mech. This field 3268-- is also set (to the default value of zero = Default_Mechanism) in a 3269-- subprogram body entity but not used in this context. 3270 3271-- Modulus (Uint17) [base type only] 3272-- Defined in modular types. Contains the modulus. For the binary case, 3273-- this will be a power of 2, but if Non_Binary_Modulus is set, then it 3274-- will not be a power of 2. 3275 3276-- Must_Be_On_Byte_Boundary (Flag183) 3277-- Defined in entities for types and subtypes. Set if objects of the type 3278-- must always be allocated on a byte boundary (more accurately a storage 3279-- unit boundary). The front end checks that component clauses respect 3280-- this rule, and the backend ensures that record packing does not 3281-- violate this rule. Currently the flag is set only for packed arrays 3282-- longer than 64 bits where the component size is not a power of 2. 3283 3284-- Must_Have_Preelab_Init (Flag208) 3285-- Defined in entities for types and subtypes. Set in the full type of a 3286-- private type or subtype if a pragma Has_Preelaborable_Initialization 3287-- is present for the private type. Used to check that the full type has 3288-- preelaborable initialization at freeze time (this has to be deferred 3289-- to the freeze point because of the rule about overriding Initialize). 3290 3291-- Needs_Debug_Info (Flag147) 3292-- Defined in all entities. Set if the entity requires normal debugging 3293-- information to be generated. This is true of all entities that have 3294-- Comes_From_Source set, and also transitively for entities associated 3295-- with such components (e.g. their types). It is true for all entities 3296-- in Debug_Generated_Code mode (-gnatD switch). This is the flag that 3297-- the backend should check to determine whether or not to generate 3298-- debugging information for an entity. Note that callers should always 3299-- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info, 3300-- so that the flag is set properly on subsidiary entities. 3301 3302-- Needs_No_Actuals (Flag22) 3303-- Defined in callable entities (subprograms, entries, access to 3304-- subprograms) which can be called without actuals because all of 3305-- their formals (if any) have default values. This flag simplifies the 3306-- resolution of the syntactic ambiguity involving a call to these 3307-- entities when the return type is an array type, and a call can be 3308-- interpreted as an indexing of the result of the call. It is also 3309-- used to resolve various cases of entry calls. 3310 3311-- Never_Set_In_Source (Flag115) 3312-- Defined in all entities, but can be set only for variables and 3313-- parameters. This flag is set if the object is never assigned a value 3314-- in user source code, either by assignment or by being used as an out 3315-- or in out parameter. Note that this flag is not reset from using an 3316-- initial value, so if you want to test for this case as well, test the 3317-- Has_Initial_Value flag also. 3318-- 3319-- This flag is only for the purposes of issuing warnings, it must not 3320-- be used by the code generator to indicate that the variable is in 3321-- fact a constant, since some assignments in generated code do not 3322-- count (for example, the call to an init proc to assign some but 3323-- not all of the fields in a partially initialized record). The code 3324-- generator should instead use the flag Is_True_Constant. 3325-- 3326-- For the purposes of this warning, the default assignment of access 3327-- variables to null is not considered the assignment of a value (so 3328-- the warning can be given for code that relies on this initial null 3329-- value when no other value is ever set). 3330-- 3331-- In variables and out parameters, if this flag is set after full 3332-- processing of the corresponding declarative unit, it indicates that 3333-- the variable or parameter was never set, and a warning message can 3334-- be issued. 3335-- 3336-- Note: this flag is initially set, and then cleared on encountering 3337-- any construct that might conceivably legitimately set the value. 3338-- Thus during the analysis of a declarative region and its associated 3339-- statement sequence, the meaning of the flag is "not set yet", and 3340-- once this analysis is complete the flag means "never assigned". 3341 3342-- Note: for variables appearing in package declarations, this flag is 3343-- never set. That is because there is no way to tell if some client 3344-- modifies the variable (or, in the case of variables in the private 3345-- part, if some child unit modifies the variables). 3346 3347-- Note: in the case of renamed objects, the flag must be set in the 3348-- ultimate renamed object. Clients noting a possible modification 3349-- should use the Note_Possible_Modification procedure in Sem_Util 3350-- rather than Set_Never_Set_In_Source precisely to deal properly with 3351-- the renaming possibility. 3352 3353-- Next_Component (synthesized) 3354-- Applies to record components. Returns the next component by following 3355-- the chain of declared entities until one is found which corresponds to 3356-- a component (Ekind is E_Component). Any internal types generated from 3357-- the subtype indications of the record components are skipped. Returns 3358-- Empty if no more components. 3359 3360-- Next_Component_Or_Discriminant (synthesized) 3361-- Similar to Next_Component, but includes components and discriminants 3362-- so the input can have either E_Component or E_Discriminant, and the 3363-- same is true for the result. Returns Empty if no more components or 3364-- discriminants in the record. 3365 3366-- Next_Discriminant (synthesized) 3367-- Applies to discriminants returned by First/Next_Discriminant. Returns 3368-- the next language-defined (ie: perhaps non-girder) discriminant by 3369-- following the chain of declared entities as long as the kind of the 3370-- entity corresponds to a discriminant. Note that the discriminants 3371-- might be the only components of the record. Returns Empty if there 3372-- are no more discriminants. 3373 3374-- Next_Entity (Node2) 3375-- Defined in all entities. The entities of a scope are chained, with 3376-- the head of the list being in the First_Entity field of the scope 3377-- entity. All entities use the Next_Entity field as a forward pointer 3378-- for this list, with Empty indicating the end of the list. Since this 3379-- field is in the base part of the entity, the access routines for this 3380-- field are in Sinfo. 3381 3382-- Next_Formal (synthesized) 3383-- Applies to the entity for a formal parameter. Returns the next formal 3384-- parameter of the subprogram or subprogram type. Returns Empty if there 3385-- are no more formals. 3386 3387-- Next_Formal_With_Extras (synthesized) 3388-- Applies to the entity for a formal parameter. Returns the next 3389-- formal parameter of the subprogram or subprogram type. Returns 3390-- Empty if there are no more formals. The list returned includes 3391-- all the extra formals (see description of Extra_Formal field) 3392 3393-- Next_Index (synthesized) 3394-- Applies to array types and subtypes and to string types and 3395-- subtypes. Yields the next index. The first index is obtained by 3396-- using the First_Index attribute, and then subsequent indexes are 3397-- obtained by applying Next_Index to the previous index. Empty is 3398-- returned to indicate that there are no more indexes. Note that 3399-- unlike most attributes in this package, Next_Index applies to 3400-- nodes for the indexes, not to entities. 3401 3402-- Next_Inlined_Subprogram (Node12) 3403-- Defined in subprograms. Used to chain inlined subprograms used in 3404-- the current compilation, in the order in which they must be compiled 3405-- by the backend to insure that all inlinings are performed. 3406 3407-- Next_Literal (synthesized) 3408-- Applies to enumeration literals, returns the next literal, or 3409-- Empty if applied to the last literal. This is actually a synonym 3410-- for Next, but its use is preferred in this context. 3411 3412-- No_Dynamic_Predicate_On_Actual (Flag276) 3413-- Defined in discrete types. Set for generic formal types that are used 3414-- in loops and quantified expressions. The corresponing actual cannot 3415-- have dynamic predicates. 3416 3417-- No_Pool_Assigned (Flag131) [root type only] 3418-- Defined in access types. Set if a storage size clause applies to the 3419-- variable with a static expression value of zero. This flag is used to 3420-- generate errors if any attempt is made to allocate or free an instance 3421-- of such an access type. This is set only in the root type, since 3422-- derived types must have the same pool. 3423 3424-- No_Predicate_On_Actual (Flag275) 3425-- Defined in discrete types. Set for generic formal types that are used 3426-- in the spec of a generic package, in constructs that forbid discrete 3427-- types with predicates. 3428 3429-- No_Return (Flag113) 3430-- Defined in all entities. Always false except in the case of procedures 3431-- and generic procedures for which a pragma No_Return is given. 3432 3433-- No_Strict_Aliasing (Flag136) [base type only] 3434-- Defined in access types. Set to direct the backend to avoid any 3435-- optimizations based on an assumption about the aliasing status of 3436-- objects designated by the access type. For the case of the gcc 3437-- backend, the effect is as though all references to objects of 3438-- the type were compiled with -fno-strict-aliasing. This flag is 3439-- set if an unchecked conversion with the access type as a target 3440-- type occurs in the same source unit as the declaration of the 3441-- access type, or if an explicit pragma No_Strict_Aliasing applies. 3442 3443-- No_Tagged_Streams_Pragma (Node32) 3444-- Present in all subtype and type entities. Set for tagged types and 3445-- subtypes (i.e. entities with Is_Tagged_Type set True) if a valid 3446-- pragma/aspect applies to the type. 3447 3448-- Non_Binary_Modulus (Flag58) [base type only] 3449-- Defined in all subtype and type entities. Set for modular integer 3450-- types if the modulus value is other than a power of 2. 3451 3452-- Non_Limited_View (Node17) 3453-- Defined in abstract states and incomplete types that act as shadow 3454-- entities created when analysing a limited with clause (Ada 2005: 3455-- AI-50217). Points to the defining entity of the original declaration. 3456 3457-- Nonzero_Is_True (Flag162) [base type only] 3458-- Defined in enumeration types. Set if any non-zero value is to be 3459-- interpreted as true. Currently this is set for derived Boolean 3460-- types which have a convention of C, C++ or Fortran. 3461 3462-- Normalized_First_Bit (Uint8) 3463-- Defined in components and discriminants. Indicates the normalized 3464-- value of First_Bit for the component, i.e. the offset within the 3465-- lowest addressed storage unit containing part or all of the field. 3466-- Set to No_Uint if no first bit position is assigned yet. 3467 3468-- Normalized_Position (Uint14) 3469-- Defined in components and discriminants. Indicates the normalized 3470-- value of Position for the component, i.e. the offset in storage 3471-- units from the start of the record to the lowest addressed storage 3472-- unit containing part or all of the field. 3473 3474-- Normalized_Position_Max (Uint10) 3475-- Defined in components and discriminants. For almost all cases, this 3476-- is the same as Normalized_Position. The one exception is for the case 3477-- of a discriminated record containing one or more arrays whose length 3478-- depends on discriminants. In this case, the Normalized_Position_Max 3479-- field represents the maximum possible value of Normalized_Position 3480-- assuming min/max values for discriminant subscripts in all fields. 3481-- This is used by Layout in front end layout mode to properly computed 3482-- the maximum size such records (needed for allocation purposes when 3483-- there are default discriminants, and also for the 'Size value). 3484 3485-- Number_Dimensions (synthesized) 3486-- Applies to array types and subtypes. Returns the number of dimensions 3487-- of the array type or subtype as a value of type Pos. 3488 3489-- Number_Entries (synthesized) 3490-- Applies to concurrent types. Returns the number of entries that are 3491-- declared within the task or protected definition for the type. 3492 3493-- Number_Formals (synthesized) 3494-- Applies to subprograms and subprogram types. Yields the number of 3495-- formals as a value of type Pos. 3496 3497-- OK_To_Rename (Flag247) 3498-- Defined only in entities for variables. If this flag is set, it 3499-- means that if the entity is used as the initial value of an object 3500-- declaration, the object declaration can be safely converted into a 3501-- renaming to avoid an extra copy. This is set for variables which are 3502-- generated by the expander to hold the result of evaluating some 3503-- expression. Most notably, the local variables used to store the result 3504-- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It 3505-- is only worth setting this flag for composites, since for primitive 3506-- types, it is cheaper to do the copy. 3507 3508-- OK_To_Reorder_Components (Flag239) [base type only] 3509-- Defined in record types. Set if the backend is permitted to reorder 3510-- the components. If not set, the record must be layed out in the order 3511-- in which the components are declared textually. Currently this flag 3512-- can only be set by debug switches. 3513 3514-- Optimize_Alignment_Space (Flag241) 3515-- Defined in type, subtype, variable, and constant entities. This 3516-- flag records that the type or object is to be layed out in a manner 3517-- consistent with Optimize_Alignment (Space) mode. The compiler and 3518-- binder ensure a consistent view of any given type or object. If pragma 3519-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3520-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3521 3522-- Optimize_Alignment_Time (Flag242) 3523-- Defined in type, subtype, variable, and constant entities. This 3524-- flag records that the type or object is to be layed out in a manner 3525-- consistent with Optimize_Alignment (Time) mode. The compiler and 3526-- binder ensure a consistent view of any given type or object. If pragma 3527-- Optimize_Alignment (Off) mode applies to the type/object, then neither 3528-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set. 3529 3530-- Original_Access_Type (Node28) 3531-- Defined in E_Access_Subprogram_Type entities. Set only if the access 3532-- type was generated by the expander as part of processing an access 3533-- to protected subprogram type. Points to the access to protected 3534-- subprogram type. 3535 3536-- Original_Array_Type (Node21) 3537-- Defined in modular types and array types and subtypes. Set only if 3538-- the Is_Packed_Array_Impl_Type flag is set, indicating that the type 3539-- is the implementation type for a packed array, and in this case it 3540-- points to the original array type for which this is the packed 3541-- array implementation type. 3542 3543-- Original_Record_Component (Node22) 3544-- Defined in components, including discriminants. The usage depends 3545-- on whether the record is a base type and whether it is tagged. 3546-- 3547-- In base tagged types: 3548-- When the component is inherited in a record extension, it points 3549-- to the original component (the entity of the ancestor component 3550-- which is not itself inherited) otherwise it points to itself. The 3551-- backend uses this attribute to implement the automatic dereference 3552-- in the extension and to apply the transformation: 3553-- 3554-- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp 3555-- 3556-- In base untagged types: 3557-- Always points to itself except for non-girder discriminants, where 3558-- it points to the girder discriminant it renames. 3559-- 3560-- In subtypes (tagged and untagged): 3561-- Points to the component in the base type. 3562 3563-- Overlays_Constant (Flag243) 3564-- Defined in all entities. Set only for a variable for which there is 3565-- an address clause which causes the variable to overlay a constant. 3566 3567-- Overridden_Operation (Node26) 3568-- Defined in subprograms. For overriding operations, points to the 3569-- user-defined parent subprogram that is being overridden. Note: this 3570-- attribute uses the same field as Static_Initialization. The latter 3571-- is only defined for internal initialization procedures, for which 3572-- Overridden_Operation is irrelevant. Thus this attribute must not be 3573-- set for init_procs. 3574 3575-- Package_Instantiation (Node26) 3576-- Defined in packages and generic packages. When defined, this field 3577-- references an N_Generic_Instantiation node associated with an 3578-- instantiated package. In the case where the referenced node has 3579-- been rewritten to an N_Package_Specification, the instantiation 3580-- node is available from the Original_Node field of the package spec 3581-- node. This is currently not guaranteed to be set in all cases, but 3582-- when set, the field is used in Get_Package_Instantiation_Node as 3583-- one of the means of obtaining the instantiation node. Eventually 3584-- it should be set in all cases, including package entities associated 3585-- with formal packages. ??? 3586 3587-- Packed_Array_Impl_Type (Node23) 3588-- Defined in array types and subtypes, including the string literal 3589-- subtype case, if the corresponding type is packed (either bit packed 3590-- or packed to eliminate holes in non-contiguous enumeration type index 3591-- types). References the type used to represent the packed array, which 3592-- is either a modular type for short static arrays, or an array of 3593-- System.Unsigned. Note that in some situations (internal types, and 3594-- references to fields of variant records), it is not always possible 3595-- to construct this type in advance of its use. If this field is empty, 3596-- then the necessary type is declared on the fly for each reference to 3597-- the array. 3598 3599-- Parameter_Mode (synthesized) 3600-- Applies to formal parameter entities. This is a synonym for Ekind, 3601-- used when obtaining the formal kind of a formal parameter (the result 3602-- is one of E_[In/Out/In_Out]_Parameter) 3603 3604-- Parent_Subtype (Node19) [base type only] 3605-- Defined in E_Record_Type. Set only for derived tagged types, in which 3606-- case it points to the subtype of the parent type. This is the type 3607-- that is used as the Etype of the _parent field. 3608 3609-- Part_Of_Constituents (Elist9) 3610-- Present in abstract state entities. Contains all constituents that are 3611-- subject to indicator Part_Of (both aspect and option variants). 3612 3613-- Partial_View_Has_Unknown_Discr (Flag280) 3614-- Present in all types. Set to Indicate that the partial view of a type 3615-- has unknown discriminants. A default initialization of an object of 3616-- the type does not require an invariant check (AI12-0133). 3617 3618-- Pending_Access_Types (Elist15) 3619-- Defined in all types. Set for incomplete, private, Taft-amendment 3620-- types, and their corresponding full views. This list contains all 3621-- access types, both named and anonymous, declared between the partial 3622-- and the full view. The list is used by the finalization machinery to 3623-- ensure that the finalization masters of all pending access types are 3624-- fully initialized when the full view is frozen. 3625 3626-- Postconditions_Proc (Node14) 3627-- Defined in functions, procedures, entries, and entry families. Refers 3628-- to the entity of the _Postconditions procedure used to check contract 3629-- assertions on exit from a subprogram. 3630 3631-- PPC_Wrapper (Node25) 3632-- Defined in entries and entry families. Set only if pre- or post- 3633-- conditions are present. The precondition_wrapper body is the original 3634-- entry call, decorated with the given precondition for the entry. 3635 3636-- Predicate_Function (synthesized) 3637-- Defined in all types. Set for types for which (Has_Predicates is True) 3638-- and for which a predicate procedure has been built that tests that the 3639-- specified predicates are True. Contains the entity for the function 3640-- which takes a single argument of the given type, and returns True if 3641-- the predicate holds and False if it does not. 3642-- 3643-- Note: the reason this is marked as a synthesized attribute is that the 3644-- way this is stored is as an element of the Subprograms_For_Type field. 3645 3646-- Predicate_Function_M (synthesized) 3647-- Defined in all types. Present only if Predicate_Function is present, 3648-- and only if the predicate function has Raise_Expression nodes. It 3649-- is the special version created for membership tests, where if one of 3650-- these raise expressions is executed, the result is to return False. 3651 3652-- Primitive_Operations (synthesized) 3653-- Defined in concurrent types, tagged record types and subtypes, tagged 3654-- private types and tagged incomplete types. For concurrent types whose 3655-- Corresponding_Record_Type (CRT) is available, returns the list of 3656-- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist. 3657-- For all the other types returns the Direct_Primitive_Operations. 3658 3659-- Prival (Node17) 3660-- Defined in private components of protected types. Refers to the entity 3661-- of the component renaming declaration generated inside protected 3662-- subprograms, entries or barrier functions. 3663 3664-- Prival_Link (Node20) 3665-- Defined in constants and variables which rename private components of 3666-- protected types. Set to the original private component. 3667 3668-- Private_Dependents (Elist18) 3669-- Defined in private (sub)types. Records the subtypes of the private 3670-- type, derivations from it, and records and arrays with components 3671-- dependent on the type. 3672-- 3673-- The subtypes are traversed when installing and deinstalling (the full 3674-- view of) a private type in order to ensure correct view of the 3675-- subtypes. 3676-- 3677-- Used in similar fashion for incomplete types: holds list of subtypes 3678-- of these incomplete types that have discriminant constraints. The 3679-- full views of these subtypes are constructed when the full view of 3680-- the incomplete type is processed. 3681 3682-- In addition, if the incomplete type is the designated type in an 3683-- access definition for an access parameter, the operation may be 3684-- a dispatching primitive operation, which is only known when the full 3685-- declaration of the type is seen. Subprograms that have such an 3686-- access parameter are also placed in the list of private_dependents. 3687 3688-- Private_View (Node22) 3689-- For each private type, three entities are allocated, the private view, 3690-- the full view, and the shadow entity. The shadow entity contains a 3691-- copy of the private view and is used for restoring the proper private 3692-- view after a region in which the full view is visible (and is copied 3693-- into the entity normally used for the private view during this period 3694-- of visibility). The Private_View field is self-referential when the 3695-- private view lives in its normal entity, but in the copy that is made 3696-- in the shadow entity, it points to the proper location in which to 3697-- restore the private view saved in the shadow. 3698 3699-- Protected_Formal (Node22) 3700-- Defined in formal parameters (in, in out and out parameters). Used 3701-- only for formals of protected operations. References corresponding 3702-- formal parameter in the unprotected version of the operation that 3703-- is created during expansion. 3704 3705-- Protected_Body_Subprogram (Node11) 3706-- Defined in protected operations. References the entity for the 3707-- subprogram which implements the body of the operation. 3708 3709-- Protection_Object (Node23) 3710-- Applies to protected entries, entry families and subprograms. Denotes 3711-- the entity which is used to rename the _object component of protected 3712-- types. 3713 3714-- Reachable (Flag49) 3715-- Defined in labels. The flag is set over the range of statements in 3716-- which a goto to that label is legal. 3717 3718-- Referenced (Flag156) 3719-- Defined in all entities. Set if the entity is referenced, except for 3720-- the case of an appearance of a simple variable that is not a renaming 3721-- as the left side of an assignment in which case Referenced_As_LHS is 3722-- set instead, or a similar appearance as an out parameter actual, in 3723-- which case Referenced_As_Out_Parameter is set. 3724 3725-- Referenced_As_LHS (Flag36): 3726-- Defined in all entities. This flag is set instead of Referenced if a 3727-- simple variable that is not a renaming appears as the left side of an 3728-- assignment. The reason we distinguish this kind of reference is that 3729-- we have a separate warning for variables that are only assigned and 3730-- never read. 3731 3732-- Referenced_As_Out_Parameter (Flag227): 3733-- Defined in all entities. This flag is set instead of Referenced if a 3734-- simple variable that is not a renaming appears as an actual for an out 3735-- formal. The reason we distinguish this kind of reference is that 3736-- we have a separate warning for variables that are only assigned and 3737-- never read, and out parameters are a special case. 3738 3739-- Refinement_Constituents (Elist8) 3740-- Present in abstract state entities. Contains all the constituents that 3741-- refine the state, in other words, all the hidden states that appear in 3742-- the constituent_list of aspect/pragma Refined_State. 3743 3744-- Register_Exception_Call (Node20) 3745-- Defined in exception entities. When an exception is declared, 3746-- a call is expanded to Register_Exception. This field points to 3747-- the expanded N_Procedure_Call_Statement node for this call. It 3748-- is used for Import/Export_Exception processing to modify the 3749-- register call to make appropriate entries in the special tables 3750-- used for handling these pragmas at runtime. 3751 3752-- Related_Array_Object (Node25) 3753-- Defined in array types and subtypes. Used only for the base type 3754-- and subtype created for an anonymous array object. Set to point 3755-- to the entity of the corresponding array object. Currently used 3756-- only for type-related error messages. 3757 3758-- Related_Expression (Node24) 3759-- Defined in variables and types. When Set for internally generated 3760-- entities, it may be used to denote the source expression whose 3761-- elaboration created the variable declaration. If set, it is used 3762-- for generating clearer messages from CodePeer. It is used on source 3763-- entities that are variables in iterator specifications, to provide 3764-- a link to the container that is the domain of iteration. This allows 3765-- for better cross-reference information when the loop modifies elements 3766-- of the container, and suppresses spurious warnings. 3767-- 3768-- Shouldn't it also be used for the same purpose in errout? It seems 3769-- odd to have two mechanisms here??? 3770 3771-- Related_Instance (Node15) 3772-- Defined in the wrapper packages created for subprogram instances. 3773-- The internal subprogram that implements the instance is inside the 3774-- wrapper package, but for debugging purposes its external symbol 3775-- must correspond to the name and scope of the related instance. 3776 3777-- Related_Type (Node27) 3778-- Defined in components, constants and variables. Set when there is an 3779-- associated dispatch table to point to entities containing primary or 3780-- secondary tags. Not set in the _tag component of record types. 3781 3782-- Relative_Deadline_Variable (Node28) [implementation base type only] 3783-- Defined in task type entities. This flag is set if a valid and 3784-- effective pragma Relative_Deadline applies to the base type. Points 3785-- to the entity for a variable that is created to hold the value given 3786-- in a Relative_Deadline pragma for a task type. 3787 3788-- Renamed_Entity (Node18) 3789-- Defined in exceptions, packages, subprograms, and generic units. Set 3790-- for entities that are defined by a renaming declaration. Denotes the 3791-- renamed entity, or transitively the ultimate renamed entity if 3792-- there is a chain of renaming declarations. Empty if no renaming. 3793 3794-- Renamed_In_Spec (Flag231) 3795-- Defined in package entities. If a package renaming occurs within 3796-- a package spec, then this flag is set on the renamed package. The 3797-- purpose is to prevent a warning about unused entities in the renamed 3798-- package. Such a warning would be inappropriate since clients of the 3799-- package can see the entities in the package via the renaming. 3800 3801-- Renamed_Object (Node18) 3802-- Defined in all objects (constants, variables, components, formal 3803-- parameters, generic formal parameters, and loop parameters). 3804-- ??? Defined in discriminants? 3805-- Set non-Empty if the object was declared by a renaming declaration, 3806-- in which case it references the tree node for the name of the renamed 3807-- object. This is only possible for the variable and constant cases. 3808-- For formal parameters, this field is used in the course of inline 3809-- expansion, to map the formals of a subprogram into the corresponding 3810-- actuals. For formals of a task entry, it denotes the local renaming 3811-- that replaces the actual within the accept statement. The field is 3812-- Empty otherwise (it is always empty for loop parameters). 3813 3814-- Renaming_Map (Uint9) 3815-- Defined in generic subprograms, generic packages, and their 3816-- instances. Also defined in the instances of the corresponding 3817-- bodies. Denotes the renaming map (generic entities => instance 3818-- entities) used to construct the instance by givin an index into 3819-- the tables used to represent these maps. See Sem_Ch12 for further 3820-- details. The maps for package instances are also used when the 3821-- instance is the actual corresponding to a formal package. 3822 3823-- Requires_Overriding (Flag213) 3824-- Defined in all subprograms and entries. Set for subprograms that 3825-- require overriding as defined by RM-2005-3.9.3(6/2). Note that this 3826-- is True only for implicitly declare subprograms; it is not set on the 3827-- parent type's subprogram. See also Is_Abstract_Subprogram. 3828 3829-- Return_Present (Flag54) 3830-- Defined in function and generic function entities. Set if the 3831-- function contains a return statement (used for error checking). 3832-- This flag can also be set in procedure and generic procedure 3833-- entities (for convenience in setting it), but is only tested 3834-- for the function case. 3835 3836-- Return_Applies_To (Node8) 3837-- Defined in E_Return_Statement. Points to the entity representing 3838-- the construct to which the return statement applies, as defined in 3839-- RM-6.5(4/2). Note that a (simple) return statement within an 3840-- extended_return_statement applies to the extended_return_statement, 3841-- even though it causes the whole function to return. 3842 3843-- Returns_By_Ref (Flag90) 3844-- Defined in function entities. Set if the function returns the result 3845-- by reference, either because its return type is a by-reference-type 3846-- or because the function explicitly uses the secondary stack. 3847 3848-- Returns_Limited_View (Flag134) 3849-- Defined in function entities. Set if the return type of the function 3850-- at the point of definition is a limited view. Used to handle the late 3851-- freezing of the function when it is called in the current semantic 3852-- unit while it is still unfrozen. 3853 3854-- Reverse_Bit_Order (Flag164) [base type only] 3855-- Defined in all record type entities. Set if entity has a Bit_Order 3856-- aspect (set by an aspect clause or attribute definition clause) that 3857-- has reversed the order of bits from the default value. When this flag 3858-- is set, a component clause must specify a set of bits entirely within 3859-- a single storage unit (Ada 95) or within a single machine scalar (see 3860-- Ada 2005 AI-133), or must occupy an integral number of storage units. 3861 3862-- Reverse_Storage_Order (Flag93) [base type only] 3863-- Defined in all record and array type entities. Set if entity has a 3864-- Scalar_Storage_Order aspect (set by an aspect clause or attribute 3865-- definition clause) that has reversed the order of storage elements 3866-- from the default value. When this flag is set for a record type, 3867-- the Bit_Order aspect must be set to the same value (either explicitly 3868-- or as the target default value). 3869 3870-- RM_Size (Uint13) 3871-- Defined in all type and subtype entities. Contains the value of 3872-- type'Size as defined in the RM. See also the Esize field and 3873-- and the description on "Handling of Type'Size Values". A value 3874-- of zero in this field for a non-discrete type means that 3875-- the front end has not yet determined the size value. For the 3876-- case of a discrete type, this field is always set by the front 3877-- end and zero is a legitimate value for a type with one value. 3878 3879-- Root_Type (synthesized) 3880-- Applies to all type entities. For class-wide types, return the root 3881-- type of the class covered by the CW type, otherwise returns the 3882-- ultimate derivation ancestor of the given type. This function 3883-- preserves the view, i.e. the Root_Type of a partial view is the 3884-- partial view of the ultimate ancestor, the Root_Type of a full view 3885-- is the full view of the ultimate ancestor. Note that this function 3886-- does not correspond exactly to the use of root type in the RM, since 3887-- in the RM root type applies to a class of types, not to a type. 3888 3889-- Scalar_Range (Node20) 3890-- Defined in all scalar types (including modular types, where the 3891-- bounds are 0 .. modulus - 1). References a node in the tree that 3892-- contains the bounds for the range. Note that this information 3893-- could be obtained by rummaging around the tree, but it is more 3894-- convenient to have it immediately at hand in the entity. The 3895-- contents of Scalar_Range can either be an N_Subtype_Indication 3896-- node (with a constraint), or a Range node, but not a simple 3897-- subtype reference (a subtype is converted into a range). 3898 3899-- Scale_Value (Uint16) 3900-- Defined in decimal fixed-point types and subtypes. Contains the scale 3901-- for the type (i.e. the value of type'Scale = the number of decimal 3902-- digits after the decimal point). 3903 3904-- Scope (Node3) 3905-- Defined in all entities. Points to the entity for the scope (block, 3906-- loop, subprogram, package etc.) in which the entity is declared. 3907-- Since this field is in the base part of the entity node, the access 3908-- routines for this field are in Sinfo. Note that for a child unit, 3909-- the Scope will be the parent package, and for a root library unit, 3910-- the Scope will be Standard. 3911 3912-- Scope_Depth (synthesized) 3913-- Applies to program units, blocks, concurrent types and entries, and 3914-- also to record types, i.e. to any entity that can appear on the scope 3915-- stack. Yields the scope depth value, which for those entities other 3916-- than records is simply the scope depth value, for record entities, it 3917-- is the Scope_Depth of the record scope. 3918 3919-- Scope_Depth_Value (Uint22) 3920-- Defined in program units, blocks, concurrent types, and entries. 3921-- Indicates the number of scopes that statically enclose the declaration 3922-- of the unit or type. Library units have a depth of zero. Note that 3923-- record types can act as scopes but do NOT have this field set (see 3924-- Scope_Depth above) 3925 3926-- Scope_Depth_Set (synthesized) 3927-- Applies to a special predicate function that returns a Boolean value 3928-- indicating whether or not the Scope_Depth field has been set. It is 3929-- needed, since returns an invalid value in this case. 3930 3931-- Sec_Stack_Needed_For_Return (Flag167) 3932-- Defined in scope entities (blocks, functions, procedures, tasks, 3933-- entries). Set to True when secondary stack is used to hold the 3934-- returned value of a function and thus should not be released on 3935-- scope exit. 3936 3937-- Shadow_Entities (List14) 3938-- Defined in package and generic package entities. Points to a list 3939-- of entities that correspond to private types. For each private type 3940-- a shadow entity is created that holds a copy of the private view. 3941-- In regions of the program where the full views of these private 3942-- entities are visible, the full view is copied into the entity that 3943-- is normally used to hold the private view, but the shadow entity 3944-- copy is unchanged. The shadow entities are then used to restore the 3945-- original private views at the end of the region. This list is a 3946-- standard format list (i.e. First (Shadow_Entities) is the first 3947-- entry and subsequent entries are obtained using Next. 3948 3949-- Shared_Var_Procs_Instance (Node22) 3950-- Defined in variables. Set non-Empty only if Is_Shared_Passive is 3951-- set, in which case this is the entity for the associated instance of 3952-- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details. 3953 3954-- Size_Check_Code (Node19) 3955-- Defined in constants and variables. Normally Empty. Set if code is 3956-- generated to check the size of the object. This field is used to 3957-- suppress this code if a subsequent address clause is encountered. 3958 3959-- Size_Clause (synthesized) 3960-- Applies to all entities. If a size clause is present in the rep 3961-- item chain for an entity then the attribute definition clause node 3962-- for the size clause is returned. Otherwise Size_Clause returns Empty 3963-- if no item is present. Usually this is only meaningful if the flag 3964-- Has_Size_Clause is set. This is because when the representation item 3965-- chain is copied for a derived type, it can inherit a size clause that 3966-- is not applicable to the entity. 3967 3968-- Size_Depends_On_Discriminant (Flag177) 3969-- Defined in all entities for types and subtypes. Indicates that the 3970-- size of the type depends on the value of one or more discriminants. 3971-- Currently, this flag is only set for arrays which have one or more 3972-- bounds depending on a discriminant value. 3973 3974-- Size_Known_At_Compile_Time (Flag92) 3975-- Defined in all entities for types and subtypes. Indicates that the 3976-- size of objects of the type is known at compile time. This flag is 3977-- used to optimize some generated code sequences, and also to enable 3978-- some error checks (e.g. disallowing component clauses on variable 3979-- length objects). It is set conservatively (i.e. if it is True, the 3980-- size is certainly known at compile time, if it is False, then the 3981-- size may or may not be known at compile time, but the code will 3982-- assume that it is not known). 3983 3984-- Small_Value (Ureal21) 3985-- Defined in fixed point types. Points to the universal real for the 3986-- Small of the type, either as given in a representation clause, or 3987-- as computed (as a power of two) by the compiler. 3988 3989-- SPARK_Aux_Pragma (Node33) 3990-- Present in package spec and body entities. For a package spec entity 3991-- it relates to the SPARK mode setting for the private part. This field 3992-- points to the N_Pragma node that applies to the private part. This is 3993-- either set with a local SPARK_Mode pragma in the private part or it is 3994-- inherited from the SPARK mode that applies to the rest of the spec. 3995-- For a package body, it similarly applies to the SPARK mode setting for 3996-- the elaboration sequence after the BEGIN. In the case where the pragma 3997-- is inherited, the SPARK_Aux_Pragma_Inherited flag is set in the 3998-- package spec or body entity. 3999 4000-- SPARK_Aux_Pragma_Inherited (Flag266) 4001-- Present in the entities of subprogram specs and bodies as well as 4002-- in package specs and bodies. Set if the SPARK_Aux_Pragma field 4003-- points to a pragma that is inherited, rather than a local one. 4004 4005-- SPARK_Pragma (Node32) 4006-- Present in the entities of subprogram specs and bodies as well as in 4007-- package specs and bodies. Points to the N_Pragma node that applies to 4008-- the spec or body. This is either set by a local SPARK_Mode pragma or 4009-- is inherited from the context (from an outer scope for the spec case 4010-- or from the spec for the body case). In the case where it is inherited 4011-- the flag SPARK_Pragma_Inherited is set. Empty if no SPARK_Mode pragma 4012-- is applicable. 4013 4014-- SPARK_Pragma_Inherited (Flag265) 4015-- Present in the entities of subprogram specs and bodies as well as in 4016-- package specs and bodies. Set if the SPARK_Pragma field points to a 4017-- pragma that is inherited, rather than a local one. 4018 4019-- Spec_Entity (Node19) 4020-- Defined in package body entities. Points to corresponding package 4021-- spec entity. Also defined in subprogram body parameters in the 4022-- case where there is a separate spec, where this field references 4023-- the corresponding parameter entities in the spec. 4024 4025-- SSO_Set_High_By_Default (Flag273) [base type only] 4026-- Defined for record and array types. Set in the base type if a pragma 4027-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4028-- the record or array was declared and therefore applies to it. 4029 4030-- SSO_Set_Low_By_Default (Flag272) [base type only] 4031-- Defined for record and array types. Set in the base type if a pragma 4032-- Default_Scalar_Storage_Order (High_Order_First) was active at the time 4033-- the record or array was declared and therefore applies to it. 4034 4035-- Static_Discrete_Predicate (List25) 4036-- Defined in discrete types/subtypes with static predicates (with the 4037-- two flags Has_Predicates and Has_Static_Predicate set). Set if the 4038-- type/subtype has a static predicate. Points to a list of expression 4039-- and N_Range nodes that represent the predicate in canonical form. The 4040-- canonical form has entries sorted in ascending order, with duplicates 4041-- eliminated, and adjacent ranges coalesced, so that there is always a 4042-- gap in the values between successive entries. The entries in this list 4043-- are fully analyzed and typed with the base type of the subtype. Note 4044-- that all entries are static and have values within the subtype range. 4045 4046-- Static_Real_Or_String_Predicate (Node25) 4047-- Defined in real types/subtypes with static predicates (with the two 4048-- flags Has_Predicates and Has_Static_Predicate set). Set if the type 4049-- or subtype has a static predicate. Points to the return expression 4050-- of the predicate function. This is the original expression given as 4051-- the predicate except that occurrences of the type are replaced by 4052-- occurrences of the formal parameter of the predicate function (note 4053-- that the spec of this function including this formal parameter name) 4054-- is available from the Subprograms_For_Type field (it can be accessed 4055-- as Predicate_Function (typ). Also, in the case where a predicate is 4056-- inherited, the expression is of the form: 4057-- 4058-- expression AND THEN xxxPredicate (typ2 (ent)) 4059-- 4060-- where typ2 is the type from which the predicate is inherited, ent is 4061-- the entity for the current predicate function, and xxxPredicate is the 4062-- inherited predicate (from typ2). Finally for a predicate that inherits 4063-- from another predicate but does not add a predicate of its own, the 4064-- expression may consist of the above xxxPredicate call on its own. 4065 4066-- Status_Flag_Or_Transient_Decl (Node15) 4067-- Defined in variables and constants. Applies to objects that require 4068-- special treatment by the finalization machinery, such as extended 4069-- return results, IF and CASE expression results, and objects inside 4070-- N_Expression_With_Actions nodes. The attribute contains the entity 4071-- of a flag which specifies particular behavior over a region of code 4072-- or the declaration of a "hook" object. 4073-- In which case is it a flag, or a hook object??? 4074 4075-- Static_Elaboration_Desired (Flag77) 4076-- Defined in library-level packages. Set by the pragma of the same 4077-- name, to indicate that static initialization must be attempted for 4078-- all types declared in the package, and that a warning must be emitted 4079-- for those types to which static initialization is not available. 4080 4081-- Static_Initialization (Node30) 4082-- Defined in initialization procedures for types whose objects can be 4083-- initialized statically. The value of this attribute is a positional 4084-- aggregate whose components are compile-time static values. Used 4085-- when available in object declarations to eliminate the call to the 4086-- initialization procedure, and to minimize elaboration code. Note: 4087-- This attribute uses the same field as Overridden_Operation, which is 4088-- irrelevant in init_procs. 4089 4090-- Storage_Size_Variable (Node26) [implementation base type only] 4091-- Defined in access types and task type entities. This flag is set 4092-- if a valid and effective pragma Storage_Size applies to the base 4093-- type. Points to the entity for a variable that is created to 4094-- hold the value given in a Storage_Size pragma for an access 4095-- collection or a task type. Note that in the access type case, 4096-- this field is defined only in the root type (since derived types 4097-- share the same storage pool). 4098 4099-- Stored_Constraint (Elist23) 4100-- Defined in entities that can have discriminants (concurrent types 4101-- subtypes, record types and subtypes, private types and subtypes, 4102-- limited private types and subtypes and incomplete types). Points 4103-- to an element list containing the expressions for each of the 4104-- stored discriminants for the record (sub)type. 4105 4106-- Stores_Attribute_Old_Prefix (Flag270) 4107-- Defined in constants. Set when the constant has been generated to save 4108-- the value of attribute 'Old's prefix. 4109 4110-- Strict_Alignment (Flag145) [implementation base type only] 4111-- Defined in all type entities. Indicates that some containing part 4112-- is either aliased or tagged. This prohibits packing the object 4113-- tighter than its natural size and alignment. 4114 4115-- String_Literal_Length (Uint16) 4116-- Defined in string literal subtypes (which are created to correspond 4117-- to string literals in the program). Contains the length of the string 4118-- literal. 4119 4120-- String_Literal_Low_Bound (Node18) 4121-- Defined in string literal subtypes (which are created to correspond 4122-- to string literals in the program). Contains an expression whose 4123-- value represents the low bound of the literal. This is a copy of 4124-- the low bound of the applicable index constraint if there is one, 4125-- or a copy of the low bound of the index base type if not. 4126 4127-- Subprograms_For_Type (Node29) 4128-- Defined in all type and subprogram entities. This is used to hold 4129-- a list of subprogram entities for subprograms associated with the 4130-- type, linked through the Subprograms_For_Type field of the subprogram 4131-- entity. Basically this is a way of multiplexing the single field to 4132-- hold more than one entity (since we ran out of space in some type 4133-- entities). This is currently used for Invariant_Procedure and also 4134-- for Predicate_Function, and clients will always use the latter two 4135-- names to access entries in this list. 4136 4137-- Subps_Index (Uint24) 4138-- Used during Exp_Inst.Unnest_Subprogram to hold the index in the Subps 4139-- table for a subprogram. See processing in this procedure for details. 4140-- Note that this overlaps Uplevel_References, it is only set after the 4141-- latter field has been acquired. 4142 4143-- Suppress_Elaboration_Warnings (Flag148) 4144-- Defined in all entities, can be set only for subprogram entities and 4145-- for variables. If this flag is set then Sem_Elab will not generate 4146-- elaboration warnings for the subprogram or variable. Suppression of 4147-- such warnings is automatic for subprograms for which elaboration 4148-- checks are suppressed (without the need to set this flag), but the 4149-- flag is also set for various internal entities (such as init procs) 4150-- which are known not to generate any possible access before 4151-- elaboration, and it is set on variables when a warning is given to 4152-- avoid multiple elaboration warnings for the same variable. 4153 4154-- Suppress_Initialization (Flag105) 4155-- Defined in all variable, type and subtype entities. If set for a base 4156-- type, then the generation of initialization procedures is suppressed 4157-- for the type. Any other implicit initialiation (e.g. from the use of 4158-- pragma Initialize_Scalars) is also suppressed if this flag is set for 4159-- either the subtype in question, or for the base type. For variables, 4160-- this flag suppresses all implicit initialization for the object, even 4161-- if the type would normally require initialization. Set by use of 4162-- pragma Suppress_Initialization and also for internal entities where 4163-- we know that no initialization is required. For example, enumeration 4164-- image table entities set it. 4165 4166-- Suppress_Style_Checks (Flag165) 4167-- Defined in all entities. Suppresses any style checks specifically 4168-- associated with the given entity if set. 4169 4170-- Suppress_Value_Tracking_On_Call (Flag217) 4171-- Defined in all entities. Set in a scope entity if value tracking is to 4172-- be suppressed on any call within the scope. Used when an access to a 4173-- local subprogram is computed, to deal with the possibility that this 4174-- value may be passed around, and if used, may clobber a local variable. 4175 4176-- Task_Body_Procedure (Node25) 4177-- Defined in task types and subtypes. Points to the entity for the task 4178-- task body procedure (as further described in Exp_Ch9, task bodies are 4179-- expanded into procedures). A convenient function to retrieve this 4180-- field is Sem_Util.Get_Task_Body_Procedure. 4181-- 4182-- The last sentence is odd??? Why not have Task_Body_Procedure go to the 4183-- Underlying_Type of the Root_Type??? 4184 4185-- Thunk_Entity (Node31) 4186-- Defined in functions and procedures which have been classified as 4187-- Is_Thunk. Set to the target entity called by the thunk. 4188 4189-- Treat_As_Volatile (Flag41) 4190-- Defined in all type entities, and also in constants, components and 4191-- variables. Set if this entity is to be treated as volatile for code 4192-- generation purposes. Always set if Is_Volatile is set, but can also 4193-- be set as a result of situations (such as address overlays) where 4194-- the front end wishes to force volatile handling to inhibit aliasing 4195-- optimization which might be legally ok, but is undesirable. Note 4196-- that the backend always tests this flag rather than Is_Volatile. 4197-- The front end tests Is_Volatile if it is concerned with legality 4198-- checks associated with declared volatile variables, but if the test 4199-- is for the purposes of suppressing optimizations, then the front 4200-- end should test Treat_As_Volatile rather than Is_Volatile. 4201-- 4202-- Note: before testing Treat_As_Volatile, consider whether it would 4203-- be more appropriate to use Exp_Util.Is_Volatile_Reference instead, 4204-- which catches more cases of volatile references. 4205 4206-- Type_High_Bound (synthesized) 4207-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4208-- the high bound of a scalar type. The returned value is literal for a 4209-- base type, but may be an expression in the case of scalar type with 4210-- dynamic bounds. Note that in the case of a fixed point type, the high 4211-- bound is in units of small, and is an integer. 4212 4213-- Type_Low_Bound (synthesized) 4214-- Applies to scalar types. Returns the tree node (Node_Id) that contains 4215-- the low bound of a scalar type. The returned value is literal for a 4216-- base type, but may be an expression in the case of scalar type with 4217-- dynamic bounds. Note that in the case of a fixed point type, the low 4218-- bound is in units of small, and is an integer. 4219 4220-- Underlying_Full_View (Node19) 4221-- Defined in private subtypes that are the completion of other private 4222-- types, or in private types that are derived from private subtypes. If 4223-- the full view of a private type T is derived from another private type 4224-- with discriminants Td, the full view of T is also private, and there 4225-- is no way to attach to it a further full view that would convey the 4226-- structure of T to the backend. The Underlying_Full_View is an 4227-- attribute of the full view that is a subtype of Td with the same 4228-- constraint as the declaration for T. The declaration for this subtype 4229-- is built at the point of the declaration of T, either as completion, 4230-- or as a subtype declaration where the base type is private and has a 4231-- private completion. If Td is already constrained, then its full view 4232-- can serve directly as the full view of T. 4233 4234-- Underlying_Record_View (Node28) 4235-- Defined in record types. Set for record types that are extensions of 4236-- types with unknown discriminants, and also set for internally built 4237-- underlying record views to reference its original record type. Record 4238-- types that are extensions of types with unknown discriminants do not 4239-- have a completion, but they cannot be used without having some 4240-- discriminated view at hand. This view is a record type with the same 4241-- structure, whose parent type is the full view of the parent in the 4242-- original type extension. 4243 4244-- Underlying_Type (synthesized) 4245-- Applies to all entities. This is the identity function except in the 4246-- case where it is applied to an incomplete or private type, in which 4247-- case it is the underlying type of the type declared by the completion, 4248-- or Empty if the completion has not yet been encountered and analyzed. 4249-- 4250-- Note: the reason this attribute applies to all entities, and not just 4251-- types, is to legitimize code where Underlying_Type is applied to an 4252-- entity which may or may not be a type, with the intent that if it is a 4253-- type, its underlying type is taken. 4254-- 4255-- Note also that the value of this attribute is interesting only after 4256-- the full view of the parent type has been processed. If the parent 4257-- type is declared in an enclosing package, the attribute will be non- 4258-- trivial only after the full view of the type has been analyzed. 4259 4260-- Universal_Aliasing (Flag216) [implementation base type only] 4261-- Defined in all type entities. Set to direct the back-end to avoid 4262-- any optimizations based on type-based alias analysis for this type. 4263-- Indicates that objects of this type can alias objects of any other 4264-- types, which guarantees that any objects can be referenced through 4265-- access types designating this type safely, whatever the actual type 4266-- of these objects. In other words, the effect is as though access 4267-- types designating this type were subject to No_Strict_Aliasing. 4268 4269-- Unset_Reference (Node16) 4270-- Defined in variables and out parameters. This is normally Empty. It 4271-- is set to point to an identifier that represents a reference to the 4272-- entity before any value has been set. Only the first such reference 4273-- is identified. This field is used to generate a warning message if 4274-- necessary (see Sem_Warn.Check_Unset_Reference). 4275 4276-- Uplevel_Reference_Noted (Flag283) 4277-- Defined in all entities, used in Exp_Unst processing to note that an 4278-- uplevel reference to the entity has been noted (to avoid processing a 4279-- given entity more than once). 4280 4281-- Uplevel_References (Elist24) 4282-- Defined in subprogram entities. Set only if Has_Uplevel_Reference is 4283-- set and if we are Unnest_Subprogram_Mode, otherwise undefined. Points 4284-- to a list of explicit uplevel references to entities declared in 4285-- the subprogram which need rewriting. Each entry uses two elements of 4286-- the list, the first is the node that is the actual reference, the 4287-- second is the entity of the enclosing subprogram for the reference. 4288 4289-- Used_As_Generic_Actual (Flag222) 4290-- Defined in all entities, set if the entity is used as an argument to 4291-- a generic instantiation. Used to tune certain warning messages. 4292 4293-- Uses_Lock_Free (Flag188) 4294-- Defined in protected type entities. Set to True when the Lock Free 4295-- implementation is used for the protected type. This implemenatation is 4296-- based on atomic transactions and doesn't require anymore the use of 4297-- Protection object (see System.Tasking.Protected_Objects). 4298 4299-- Uses_Sec_Stack (Flag95) 4300-- Defined in scope entities (block, entry, function, loop, procedure, 4301-- task). Set to True when secondary stack is used in this scope and must 4302-- be released on exit unless Sec_Stack_Needed_For_Return is set. 4303 4304-- Warnings_Off (Flag96) 4305-- Defined in all entities. Set if a pragma Warnings (Off, entity-name) 4306-- is used to suppress warnings for a given entity. It is also used by 4307-- the compiler in some situations to kill spurious warnings. Note that 4308-- clients should generally not test this flag directly, but instead 4309-- use function Has_Warnings_Off. 4310 4311-- Warnings_Off_Used (Flag236) 4312-- Defined in all entities. Can only be set if Warnings_Off is set. If 4313-- set indicates that a warning was suppressed by the Warnings_Off flag, 4314-- and Unmodified/Unreferenced would not have suppressed the warning. 4315 4316-- Warnings_Off_Used_Unmodified (Flag237) 4317-- Defined in all entities. Can only be set if Warnings_Off is set and 4318-- Has_Pragma_Unmodified is not set. If set indicates that a warning was 4319-- suppressed by the Warnings_Off status but that pragma Unmodified 4320-- would also have suppressed the warning. 4321 4322-- Warnings_Off_Used_Unreferenced (Flag238) 4323-- Defined in all entities. Can only be set if Warnings_Off is set and 4324-- Has_Pragma_Unreferenced is not set. If set indicates that a warning 4325-- was suppressed by the Warnings_Off status but that pragma Unreferenced 4326-- would also have suppressed the warning. 4327 4328-- Was_Hidden (Flag196) 4329-- Defined in all entities. Used to save the value of the Is_Hidden 4330-- attribute when the limited-view is installed (Ada 2005: AI-217). 4331 4332-- Wrapped_Entity (Node27) 4333-- Defined in functions and procedures which have been classified as 4334-- Is_Primitive_Wrapper. Set to the entity being wrapper. 4335 4336--------------------------- 4337-- Renaming and Aliasing -- 4338--------------------------- 4339 4340-- Several entity attributes relate to renaming constructs, and to the use of 4341-- different names to refer to the same entity. The following is a summary of 4342-- these constructs and their prefered uses. 4343 4344-- There are three related attributes: 4345 4346-- Renamed_Entity 4347-- Renamed_Object 4348-- Alias 4349 4350-- They all overlap because they are supposed to apply to different entity 4351-- kinds. They are semantically related, and have the following intended uses: 4352 4353-- a) Renamed_Entity appplies to entities in renaming declarations that rename 4354-- an entity, so the value of the attribute IS an entity. This applies to 4355-- generic renamings, package renamings, exception renamings, and subprograms 4356-- renamings that rename a subprogram (rather than an attribute, an entry, a 4357-- protected operation, etc). 4358 4359-- b) Alias applies to overloadable entities, and the value is an overloadable 4360-- entity. so this is a subset of the previous one. We use the term Alias to 4361-- cover both renamings and inherited operations, because both cases are 4362-- handled in the same way when expanding a call. namely the Alias of a given 4363-- subprogram is the subprogram that will actually be called. 4364 4365-- Both a) and b) are set transitively, so that in fact it is not necessary to 4366-- traverse chains of renamings when looking for the original entity: it's 4367-- there in one step (this is done when analyzing renaming declarations other 4368-- than object renamings in sem_ch8). 4369 4370-- c) Renamed_Object applies to constants and variables. Given that the name 4371-- in an object renaming declaration is not necessarily an entity name, the 4372-- value of the attribute is the tree for that name, eg AR (1).Comp. The case 4373-- when that name is in fact an entity is not handled specially. This is why 4374-- in a few cases we need to use a loop to trace a chain of object renamings 4375-- where all of them happen to be entities. So: 4376 4377-- X : integer; 4378-- Y : integer renames X; -- renamed object is the identifier X 4379-- Z : integer renames Y; -- renamed object is the identifier Y 4380 4381-- The front-end does not store explicitly the fact that Z renames X. 4382 4383-------------------------------------- 4384-- Delayed Freezing and Elaboration -- 4385-------------------------------------- 4386 4387-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit 4388-- freeze node, which appears later in the expanded tree. 4389 4390-- a) The flag is used by the front-end to trigger expansion actions 4391-- which include the generation of that freeze node. Typically this happens at 4392-- the end of the current compilation unit, or before the first subprogram 4393-- body is encountered in the current unit. See files freeze and exp_ch13 for 4394-- details on the actions triggered by a freeze node, which include the 4395-- construction of initialization procedures and dispatch tables. 4396 4397-- b) The flag is used by the backend to defer elaboration of the entity until 4398-- its freeze node is seen. In the absence of an explicit freeze node, an 4399-- entity is frozen (and elaborated) at the point of declaration. 4400 4401-- For object declarations, the flag is set when an address clause for the 4402-- object is encountered. Legality checks on the address expression only 4403-- take place at the freeze point of the object. 4404 4405-- Most types have an explicit freeze node, because they cannot be elaborated 4406-- until all representation and operational items that apply to them have been 4407-- analyzed. Private types and incomplete types have the flag set as well, as 4408-- do task and protected types. 4409 4410-- Implicit base types created for type derivations, as well as classwide 4411-- types created for all tagged types, have the flag set. 4412 4413-- If a subprogram has an access parameter whose designated type is incomplete 4414-- the subprogram has the flag set. 4415 4416------------------ 4417-- Access Kinds -- 4418------------------ 4419 4420-- The following entity kinds are introduced by the corresponding type 4421-- definitions: 4422 4423-- E_Access_Type, 4424-- E_General_Access_Type, 4425-- E_Access_Subprogram_Type, 4426-- E_Anonymous_Access_Subprogram_Type, 4427-- E_Access_Protected_Subprogram_Type, 4428-- E_Anonymous_Access_Protected_Subprogram_Type 4429-- E_Anonymous_Access_Type. 4430 4431-- E_Access_Subtype is for an access subtype created by a subtype 4432-- declaration. 4433 4434-- In addition, we define the kind E_Allocator_Type to label allocators. 4435-- This is because special resolution rules apply to this construct. 4436-- Eventually the constructs are labeled with the access type imposed by 4437-- the context. The backend should never see types with this Ekind. 4438 4439-- Similarly, the type E_Access_Attribute_Type is used as the initial kind 4440-- associated with an access attribute. After resolution a specific access 4441-- type will be established as determined by the context. 4442 4443-- Finally, the type Any_Access is used to label -null- during type 4444-- resolution. Any_Access is also replaced by the context type after 4445-- resolution. 4446 4447-------------------------------- 4448-- Classification of Entities -- 4449-------------------------------- 4450 4451-- The classification of program entities which follows is a refinement of 4452-- the list given in RM 3.1(1). E.g., separate entities denote subtypes of 4453-- different type classes. Ada 95 entities include class wide types, 4454-- protected types, subprogram types, generalized access types, generic 4455-- formal derived types and generic formal packages. 4456 4457-- The order chosen for these kinds allows us to classify related entities 4458-- so that they are contiguous. As a result, they do not appear in the 4459-- exact same order as their order of first appearance in the LRM (For 4460-- example, private types are listed before packages). The contiguity 4461-- allows us to define useful subtypes (see below) such as type entities, 4462-- overloaded entities, etc. 4463 4464-- Each entity (explicitly or implicitly declared) has a kind, which is 4465-- a value of the following type: 4466 4467 type Entity_Kind is ( 4468 4469 E_Void, 4470 -- The initial Ekind value for a newly created entity. Also used as the 4471 -- Ekind for Standard_Void_Type, a type entity in Standard used as a 4472 -- dummy type for the return type of a procedure (the reason we create 4473 -- this type is to share the circuits for performing overload resolution 4474 -- on calls). 4475 4476 ------------- 4477 -- Objects -- 4478 ------------- 4479 4480 E_Component, 4481 -- Components of a record declaration, private declarations of 4482 -- protected objects. 4483 4484 E_Constant, 4485 -- Constants created by an object declaration with a constant keyword 4486 4487 E_Discriminant, 4488 -- A discriminant, created by the use of a discriminant in a type 4489 -- declaration. 4490 4491 E_Loop_Parameter, 4492 -- A loop parameter created by a for loop 4493 4494 E_Variable, 4495 -- Variables created by an object declaration with no constant keyword 4496 4497 ------------------------ 4498 -- Parameter Entities -- 4499 ------------------------ 4500 4501 -- Parameters are also objects 4502 4503 E_Out_Parameter, 4504 -- An out parameter of a subprogram or entry 4505 4506 E_In_Out_Parameter, 4507 -- An in-out parameter of a subprogram or entry 4508 4509 E_In_Parameter, 4510 -- An in parameter of a subprogram or entry 4511 4512 -------------------------------- 4513 -- Generic Parameter Entities -- 4514 -------------------------------- 4515 4516 -- Generic parameters are also objects 4517 4518 E_Generic_In_Out_Parameter, 4519 -- A generic in out parameter, created by the use of a generic in out 4520 -- parameter in a generic declaration. 4521 4522 E_Generic_In_Parameter, 4523 -- A generic in parameter, created by the use of a generic in 4524 -- parameter in a generic declaration. 4525 4526 ------------------- 4527 -- Named Numbers -- 4528 ------------------- 4529 4530 E_Named_Integer, 4531 -- Named numbers created by a number declaration with an integer value 4532 4533 E_Named_Real, 4534 -- Named numbers created by a number declaration with a real value 4535 4536 ----------------------- 4537 -- Enumeration Types -- 4538 ----------------------- 4539 4540 E_Enumeration_Type, 4541 -- Enumeration types, created by an enumeration type declaration 4542 4543 E_Enumeration_Subtype, 4544 -- Enumeration subtypes, created by an explicit or implicit subtype 4545 -- declaration applied to an enumeration type or subtype. 4546 4547 ------------------- 4548 -- Numeric Types -- 4549 ------------------- 4550 4551 E_Signed_Integer_Type, 4552 -- Signed integer type, used for the anonymous base type of the 4553 -- integer subtype created by an integer type declaration. 4554 4555 E_Signed_Integer_Subtype, 4556 -- Signed integer subtype, created by either an integer subtype or 4557 -- integer type declaration (in the latter case an integer type is 4558 -- created for the base type, and this is the first named subtype). 4559 4560 E_Modular_Integer_Type, 4561 -- Modular integer type, used for the anonymous base type of the 4562 -- integer subtype created by a modular integer type declaration. 4563 4564 E_Modular_Integer_Subtype, 4565 -- Modular integer subtype, created by either an modular subtype 4566 -- or modular type declaration (in the latter case a modular type 4567 -- is created for the base type, and this is the first named subtype). 4568 4569 E_Ordinary_Fixed_Point_Type, 4570 -- Ordinary fixed type, used for the anonymous base type of the fixed 4571 -- subtype created by an ordinary fixed point type declaration. 4572 4573 E_Ordinary_Fixed_Point_Subtype, 4574 -- Ordinary fixed point subtype, created by either an ordinary fixed 4575 -- point subtype or ordinary fixed point type declaration (in the 4576 -- latter case a fixed point type is created for the base type, and 4577 -- this is the first named subtype). 4578 4579 E_Decimal_Fixed_Point_Type, 4580 -- Decimal fixed type, used for the anonymous base type of the decimal 4581 -- fixed subtype created by an ordinary fixed point type declaration. 4582 4583 E_Decimal_Fixed_Point_Subtype, 4584 -- Decimal fixed point subtype, created by either a decimal fixed point 4585 -- subtype or decimal fixed point type declaration (in the latter case 4586 -- a fixed point type is created for the base type, and this is the 4587 -- first named subtype). 4588 4589 E_Floating_Point_Type, 4590 -- Floating point type, used for the anonymous base type of the 4591 -- floating point subtype created by a floating point type declaration. 4592 4593 E_Floating_Point_Subtype, 4594 4595 -- Floating point subtype, created by either a floating point subtype 4596 -- or floating point type declaration (in the latter case a floating 4597 -- point type is created for the base type, and this is the first 4598 -- named subtype). 4599 4600 ------------------ 4601 -- Access Types -- 4602 ------------------ 4603 4604 E_Access_Type, 4605 -- An access type created by an access type declaration with no all 4606 -- keyword present.

Meanwhile, the access 6372 -- procedures in the body of Einfo permit many, but not all, attributes 6373 -- to be applied to an E_Void entity, precisely so that this kind of 6374 -- pre-setting of attributes works.

Of course, from the point of view of a user of this 6411 -- package, the distinction is not visible (even the field information 6412 -- provided below should be disregarded, as it is subject to change 6413 -- without notice). A number of attributes appear as lists: lists of 6414 -- formals, lists of actuals, of discriminants, etc. For these, pairs 6415 -- of functions are defined, which take the form: 6416 6417 -- function First_Thing (E : Enclosing_Construct) return Thing; 6418 -- function Next_Thing (T : Thing) return Thing; 6419 6420 -- The end of iteration is always signaled by a value of Empty, so that 6421 -- loops over these chains invariably have the form: 6422 6423 -- This : Thing; 6424 -- ... 6425 -- This := First_Thing (E); 6426 6427 -- while Present (This) loop 6428 -- Do_Something_With (This); 6429 -- ... 6430 -- This := Next_Thing (This); 6431 -- end loop; 6432 6433 ----------------------------------- 6434 -- Handling of Check Suppression -- 6435 ----------------------------------- 6436 6437 -- There are three ways that checks can be suppressed: 6438 6439 -- 1. At the command line level 6440 -- 2. At the scope level. 6441 -- 3. At the entity level. 6442 6443 -- See spec of Sem in sem.ads for details of the data structures used 6444 -- to keep track of these various methods for suppressing checks. 6445 6446 ------------------------------- 6447 -- Handling of Discriminants -- 6448 ------------------------------- 6449 6450 -- During semantic processing, discriminants are separate entities which 6451 -- reflect the semantic properties and allowed usage of discriminants in 6452 -- the language. 6453 6454 -- In the case of discriminants used as bounds, the references are handled 6455 -- directly, since special processing is needed in any case. However, there 6456 -- are two circumstances in which discriminants are referenced in a quite 6457 -- general manner, like any other variables: 6458 6459 -- In initialization expressions for records. Note that the expressions 6460 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline 6461 -- pragmas are effectively in this category, since these pragmas are 6462 -- converted to initialized record fields in the Corresponding_Record_ 6463 -- Type. 6464 6465 -- In task and protected bodies, where the discriminant values may be 6466 -- referenced freely within these bodies. Discriminants can also appear 6467 -- in bounds of entry families and in defaults of operations. 6468 6469 -- In both these cases, the discriminants must be treated essentially as 6470 -- objects. The following approach is used to simplify and minimize the 6471 -- special processing that is required. 6472 6473 -- When a record type with discriminants is analyzed, semantic processing 6474 -- creates the entities for the discriminants. It also creates additional 6475 -- sets of entities called discriminals, one for each of the discriminants, 6476 -- and the Discriminal field of the discriminant entity points to this 6477 -- additional entity, which is initially created as an uninitialized 6478 -- (E_Void) entity. 6479 6480 -- During expansion of expressions, any discriminant reference is replaced 6481 -- by a reference to the corresponding discriminal. When the initialization 6482 -- procedure for the record is created (there will always be one, since 6483 -- discriminants are present, see Exp_Ch3 for further details), the 6484 -- discriminals are used as the entities for the formal parameters of 6485 -- this initialization procedure. The references to these discriminants 6486 -- have already been replaced by references to these discriminals, which 6487 -- are now the formal parameters corresponding to the required objects. 6488 6489 -- In the case of a task or protected body, the semantics similarly creates 6490 -- a set of discriminals for the discriminants of the task or protected 6491 -- type. When the procedure is created for the task body, the parameter 6492 -- passed in is a reference to the task value type, which contains the 6493 -- required discriminant values. The expander creates a set of declarations 6494 -- of the form: 6495 6496 -- discr_nameD : constant discr_type renames _task.discr_name; 6497 6498 -- where discr_nameD is the discriminal entity referenced by the task 6499 -- discriminant, and _task is the task value passed in as the parameter. 6500 -- Again, any references to discriminants in the task body have been 6501 -- replaced by the discriminal reference, which is now an object that 6502 -- contains the required value. 6503 6504 -- This approach for tasks means that two sets of discriminals are needed 6505 -- for a task type, one for the initialization procedure, and one for the 6506 -- task body. This works out nicely, since the semantics allocates one set 6507 -- for the task itself, and one set for the corresponding record. 6508 6509 -- The one bit of trickiness arises in making sure that the right set of 6510 -- discriminals is used at the right time. First the task definition is 6511 -- processed. Any references to discriminants here are replaced by the 6512 -- corresponding *task* discriminals (the record type doesn't even exist 6513 -- yet, since it is constructed as part of the expansion of the task 6514 -- declaration, which happens after the semantic processing of the task 6515 -- definition). The discriminants to be used for the corresponding record 6516 -- are created at the same time as the other discriminals, and held in the 6517 -- CR_Discriminant field of the discriminant. A use of the discriminant in 6518 -- a bound for an entry family is replaced with the CR_Discriminant because 6519 -- it controls the bound of the entry queue array which is a component of 6520 -- the corresponding record. 6521 6522 -- Just before the record initialization routine is constructed, the 6523 -- expander exchanges the task and record discriminals. This has two 6524 -- effects. First the generation of the record initialization routine 6525 -- uses the discriminals that are now on the record, which is the set 6526 -- that used to be on the task, which is what we want. 6527 6528 -- Second, a new set of (so far unused) discriminals is now on the task 6529 -- discriminants, and it is this set that will be used for expanding the 6530 -- task body, and also for the discriminal declarations at the start of 6531 -- the task body. 6532 6533 --------------------------------------------------- 6534 -- Handling of private data in protected objects -- 6535 --------------------------------------------------- 6536 6537 -- Private components in protected types pose problems similar to those 6538 -- of discriminants. Private data is visible and can be directly referenced 6539 -- from protected bodies. However, when protected entries and subprograms 6540 -- are expanded into corresponding bodies and barrier functions, private 6541 -- components lose their original context and visibility. 6542 6543 -- To remedy this side effect of expansion, private components are expanded 6544 -- into renamings called "privals", by analogy with "discriminals". 6545 6546 -- private_comp : comp_type renames _object.private_comp; 6547 6548 -- Prival declarations are inserted during the analysis of subprogram and 6549 -- entry bodies to ensure proper visibility for any subsequent expansion. 6550 -- _Object is the formal parameter of the generated corresponding body or 6551 -- a local renaming which denotes the protected object obtained from entry 6552 -- parameter _O. Privals receive minimal decoration upon creation and are 6553 -- categorized as either E_Variable for the general case or E_Constant when 6554 -- they appear in functions. 6555 6556 -- Along with the local declarations, each private component carries a 6557 -- placeholder which references the prival entity in the current body. This 6558 -- form of indirection is used to resolve name clashes of privals and other 6559 -- locally visible entities such as parameters, local objects, entry family 6560 -- indexes or identifiers used in the barrier condition. 6561 6562 -- When analyzing the statements of a protected subprogram or entry, any 6563 -- reference to a private component must resolve to the locally declared 6564 -- prival through normal visibility. In case of name conflicts (the cases 6565 -- above), the prival is marked as hidden and acts as a weakly declared 6566 -- entity. As a result, the reference points to the correct entity. When a 6567 -- private component is denoted by an expanded name (prot_type.comp for 6568 -- example), the expansion mechanism uses the placeholder of the component 6569 -- to correct the Entity and Etype of the reference. 6570 6571 ------------------- 6572 -- Type Synonyms -- 6573 ------------------- 6574 6575 -- The following type synonyms are used to tidy up the function and 6576 -- procedure declarations that follow, and also to make it possible to meet 6577 -- the requirement for the XEINFO utility that all function specs must fit 6578 -- on a single source line. 6579 6580 subtype B is Boolean; 6581 subtype C is Component_Alignment_Kind; 6582 subtype E is Entity_Id; 6583 subtype F is Float_Rep_Kind; 6584 subtype M is Mechanism_Type; 6585 subtype N is Node_Id; 6586 subtype U is Uint; 6587 subtype R is Ureal; 6588 subtype L is Elist_Id; 6589 subtype S is List_Id; 6590 6591 -------------------------------- 6592 -- Attribute Access Functions -- 6593 -------------------------------- 6594 6595 -- All attributes are manipulated through a procedural interface.
