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

At the command line level 6143 -- 2. At the scope level. 6144 -- 3. At the entity level. 6145 6146 -- See spec of Sem in sem.ads for details of the data structures used 6147 -- to keep track of these various methods for suppressing checks. 6148 6149 ------------------------------- 6150 -- Handling of Discriminants -- 6151 ------------------------------- 6152 6153 -- During semantic processing, discriminants are separate entities which 6154 -- reflect the semantic properties and allowed usage of discriminants in 6155 -- the language. 6156 6157 -- In the case of discriminants used as bounds, the references are handled 6158 -- directly, since special processing is needed in any case. However, there 6159 -- are two circumstances in which discriminants are referenced in a quite 6160 -- general manner, like any other variables: 6161 6162 -- In initialization expressions for records. Note that the expressions 6163 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline 6164 -- pragmas are effectively in this category, since these pragmas are 6165 -- converted to initialized record fields in the Corresponding_Record_ 6166 -- Type. 6167 6168 -- In task and protected bodies, where the discriminant values may be 6169 -- referenced freely within these bodies. Discriminants can also appear 6170 -- in bounds of entry families and in defaults of operations. 6171 6172 -- In both these cases, the discriminants must be treated essentially as 6173 -- objects. The following approach is used to simplify and minimize the 6174 -- special processing that is required. 6175 6176 -- When a record type with discriminants is analyzed, semantic processing 6177 -- creates the entities for the discriminants. It also creates additional 6178 -- sets of entities called discriminals, one for each of the discriminants, 6179 -- and the Discriminal field of the discriminant entity points to this 6180 -- additional entity, which is initially created as an uninitialized 6181 -- (E_Void) entity. 6182 6183 -- During expansion of expressions, any discriminant reference is replaced 6184 -- by a reference to the corresponding discriminal. When the initialization 6185 -- procedure for the record is created (there will always be one, since 6186 -- discriminants are present, see Exp_Ch3 for further details), the 6187 -- discriminals are used as the entities for the formal parameters of 6188 -- this initialization procedure. The references to these discriminants 6189 -- have already been replaced by references to these discriminals, which 6190 -- are now the formal parameters corresponding to the required objects. 6191 6192 -- In the case of a task or protected body, the semantics similarly creates 6193 -- a set of discriminals for the discriminants of the task or protected 6194 -- type. When the procedure is created for the task body, the parameter 6195 -- passed in is a reference to the task value type, which contains the 6196 -- required discriminant values. The expander creates a set of declarations 6197 -- of the form: 6198 6199 -- discr_nameD : constant discr_type renames _task.discr_name; 6200 6201 -- where discr_nameD is the discriminal entity referenced by the task 6202 -- discriminant, and _task is the task value passed in as the parameter. 6203 -- Again, any references to discriminants in the task body have been 6204 -- replaced by the discriminal reference, which is now an object that 6205 -- contains the required value. 6206 6207 -- This approach for tasks means that two sets of discriminals are needed 6208 -- for a task type, one for the initialization procedure, and one for the 6209 -- task body. This works out nicely, since the semantics allocates one set 6210 -- for the task itself, and one set for the corresponding record. 6211 6212 -- The one bit of trickiness arises in making sure that the right set of 6213 -- discriminals is used at the right time. First the task definition is 6214 -- processed. Any references to discriminants here are replaced by the 6215 -- corresponding *task* discriminals (the record type doesn't even exist 6216 -- yet, since it is constructed as part of the expansion of the task 6217 -- declaration, which happens after the semantic processing of the task 6218 -- definition). The discriminants to be used for the corresponding record 6219 -- are created at the same time as the other discriminals, and held in the 6220 -- CR_Discriminant field of the discriminant. A use of the discriminant in 6221 -- a bound for an entry family is replaced with the CR_Discriminant because 6222 -- it controls the bound of the entry queue array which is a component of 6223 -- the corresponding record. 6224 6225 -- Just before the record initialization routine is constructed, the 6226 -- expander exchanges the task and record discriminals. This has two 6227 -- effects. First the generation of the record initialization routine 6228 -- uses the discriminals that are now on the record, which is the set 6229 -- that used to be on the task, which is what we want. 6230 6231 -- Second, a new set of (so far unused) discriminals is now on the task 6232 -- discriminants, and it is this set that will be used for expanding the 6233 -- task body, and also for the discriminal declarations at the start of 6234 -- the task body. 6235 6236 --------------------------------------------------- 6237 -- Handling of private data in protected objects -- 6238 --------------------------------------------------- 6239 6240 -- Private components in protected types pose problems similar to those 6241 -- of discriminants. Private data is visible and can be directly referenced 6242 -- from protected bodies. However, when protected entries and subprograms 6243 -- are expanded into corresponding bodies and barrier functions, private 6244 -- components lose their original context and visibility. 6245 6246 -- To remedy this side effect of expansion, private components are expanded 6247 -- into renamings called "privals", by analogy with "discriminals". 6248 6249 -- private_comp : comp_type renames _object.private_comp; 6250 6251 -- Prival declarations are inserted during the analysis of subprogram and 6252 -- entry bodies to ensure proper visibility for any subsequent expansion. 6253 -- _Object is the formal parameter of the generated corresponding body or 6254 -- a local renaming which denotes the protected object obtained from entry 6255 -- parameter _O. Privals receive minimal decoration upon creation and are 6256 -- categorized as either E_Variable for the general case or E_Constant when 6257 -- they appear in functions. 6258 6259 -- Along with the local declarations, each private component carries a 6260 -- placeholder which references the prival entity in the current body. This 6261 -- form of indirection is used to resolve name clashes of privals and other 6262 -- locally visible entities such as parameters, local objects, entry family 6263 -- indexes or identifiers used in the barrier condition. 6264 6265 -- When analyzing the statements of a protected subprogram or entry, any 6266 -- reference to a private component must resolve to the locally declared 6267 -- prival through normal visibility. In case of name conflicts (the cases 6268 -- above), the prival is marked as hidden and acts as a weakly declared 6269 -- entity. As a result, the reference points to the correct entity. When a 6270 -- private component is denoted by an expanded name (prot_type.comp for 6271 -- example), the expansion mechanism uses the placeholder of the component 6272 -- to correct the Entity and Etype of the reference. 6273 6274 ------------------- 6275 -- Type Synonyms -- 6276 ------------------- 6277 6278 -- The following type synonyms are used to tidy up the function and 6279 -- procedure declarations that follow, and also to make it possible to meet 6280 -- the requirement for the XEINFO utility that all function specs must fit 6281 -- on a single source line. 6282 6283 subtype B is Boolean; 6284 subtype C is Component_Alignment_Kind; 6285 subtype E is Entity_Id; 6286 subtype F is Float_Rep_Kind; 6287 subtype M is Mechanism_Type; 6288 subtype N is Node_Id; 6289 subtype U is Uint; 6290 subtype R is Ureal; 6291 subtype L is Elist_Id; 6292 subtype S is List_Id; 6293 6294 -------------------------------- 6295 -- Attribute Access Functions -- 6296 -------------------------------- 6297 6298 -- All attributes are manipulated through a procedural interface.
