39 -- This package defines the annotations to the abstract syntax tree that
40 -- are needed to support semantic processing of an Ada compilation.
42 -- Note that after editing this spec and the corresponding body it is
43 -- required to run ceinfo to check the consistentcy of spec and body.
44 -- See ceinfo.adb for more information about the checks made.
46 -- These annotations are for the most part attributes of declared entities,
47 -- and they correspond to conventional symbol table information. Other
48 -- attributes include sets of meanings for overloaded names, possible
49 -- types for overloaded expressions, flags to indicate deferred constants,
50 -- incomplete types, etc. These attributes are stored in available fields in
51 -- tree nodes (i.e. fields not used by the parser, as defined by the Sinfo
52 -- package specification), and accessed by means of a set of subprograms
53 -- which define an abstract interface.
55 -- There are two kinds of semantic information
57 -- First, the tree nodes with the following Nkind values:
59 -- N_Defining_Identifier
60 -- N_Defining_Character_Literal
61 -- N_Defining_Operator_Symbol
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.
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.
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.
80 --------------------------------
81 -- The XEINFO Utility Program --
82 --------------------------------
84 -- XEINFO is a utility program which automatically produces a C header file,
85 -- einfo.h from the spec and body of package Einfo. It reads the input files
86 -- einfo.ads and einfo.adb and produces the output file einfo.h. XEINFO is run
87 -- automatically by the build scripts when you do a full bootstrap.
89 -- In order for this utility program to operate correctly, the form of the
90 -- einfo.ads and einfo.adb files must meet certain requirements and be laid
91 -- out in a specific manner.
93 -- The general form of einfo.ads is as follows:
95 -- type declaration for type Entity_Kind
96 -- subtype declarations declaring subranges of Entity_Kind
97 -- subtype declarations declaring synonyms for some standard types
98 -- function specs for attributes
100 -- pragma Inline declarations
102 -- This order must be observed. There are no restrictions on the procedures,
103 -- since the C header file only includes functions (The back end is not
104 -- allowed to modify the generated tree). However, functions are required to
105 -- have headers that fit on a single line.
107 -- XEINFO reads and processes the function specs and the pragma Inlines. For
108 -- functions that are declared as inlined, XEINFO reads the corresponding body
109 -- from einfo.adb, and processes it into C code. This results in some strict
110 -- restrictions on which functions can be inlined:
112 -- The function spec must be on a single line
114 -- There can only be a single statement, contained on a single line,
115 -- not counting any pragma Assert statements.
117 -- This single statement must either be a function call with simple,
118 -- single token arguments, or it must be a membership test of the form
119 -- a in b, where a and b are single tokens.
121 -- For functions that are not inlined, there is no restriction on the body,
122 -- and XEINFO generates a direct reference in the C header file which allows
123 -- the C code in the backend to directly call the corresponding Ada body.
125 ----------------------------------
126 -- Handling of Type'Size Values --
127 ----------------------------------
129 -- The Ada 95 RM contains some rather peculiar (to us) rules on the value
130 -- of type'Size (see RM 13.3(55)). We have found that attempting to use
131 -- these RM Size values generally, and in particular for determining the
132 -- default size of objects, creates chaos, and major incompatibilities in
135 -- We proceed as follows, for discrete and fixed-point subtypes, we have
136 -- two separate sizes for each subtype:
138 -- The Object_Size, which is used for determining the default size of
139 -- objects and components. This size value can be referred to using the
140 -- Object_Size attribute. The phrase "is used" here means that it is
141 -- the basis of the determination of the size. The backend is free to
142 -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
143 -- character might be stored in 32 bits on a machine with no efficient
144 -- byte access instructions such as the Alpha.
146 -- The default rules for the value of Object_Size for fixed-point and
147 -- discrete types are as follows:
149 -- The Object_Size for base subtypes reflect the natural hardware
150 -- size in bits (see Ttypes and Cstand for integer types). For
151 -- enumeration and fixed-point base subtypes have 8, 16, 32, or 64
152 -- bits for this size, depending on the range of values to be stored.
154 -- The Object_Size of a subtype is the same as the Object_Size of
155 -- the subtype from which it is obtained.
157 -- The Object_Size of a derived base type is copied from the parent
158 -- base type, and the Object_Size of a derived first subtype is copied
159 -- from the parent first subtype.
161 -- The Value_Size which is the number of bits required to store a value
162 -- of the type. This size can be referred to using the Value_Size
163 -- attribute. This value is used to determine how tightly to pack
164 -- records or arrays with components of this type, and also affects
165 -- the semantics of unchecked conversion (unchecked conversions where
166 -- the Value_Size values differ generate a warning, and are potentially
167 -- target dependent).
169 -- The default rules for the value of Value_Size are as follows:
171 -- The Value_Size for a base subtype is the minimum number of bits
172 -- required to store all values of the type (including the sign bit
173 -- only if negative values are possible).
175 -- If a subtype statically matches the first subtype, then it has
176 -- by default the same Value_Size as the first subtype. This is a
177 -- consequence of RM 13.1(14) ("if two subtypes statically match,
178 -- then their subtype-specific aspects are the same".)
180 -- All other subtypes have a Value_Size corresponding to the minimum
181 -- number of bits required to store all values of the subtype. For
182 -- dynamic bounds, it is assumed that the value can range down or up
183 -- to the corresponding bound of the ancestor.
185 -- The RM defined attribute Size corresponds to the Value_Size attribute.
187 -- The Size attribute may be defined for a first-named subtype. This sets
188 -- the Value_Size of the first-named subtype to the given value, and the
189 -- Object_Size of this first-named subtype to the given value padded up
190 -- to an appropriate boundary. It is a consequence of the default rules
191 -- above that this Object_Size will apply to all further subtypes. On the
192 -- other hand, Value_Size is affected only for the first subtype, any
193 -- dynamic subtypes obtained from it directly, and any statically matching
194 -- subtypes. The Value_Size of any other static subtypes is not affected.
196 -- Value_Size and Object_Size may be explicitly set for any subtype using
197 -- an attribute definition clause. Note that the use of these attributes
198 -- can cause the RM 13.1(14) rule to be violated. If two access types
199 -- reference aliased objects whose subtypes have differing Object_Size
200 -- values as a result of explicit attribute definition clauses, then it
201 -- is erroneous to convert from one access subtype to the other.
203 -- At the implementation level, Esize stores the Object_Size and the
204 -- RM_Size field stores the Value_Size (and hence the value of the
205 -- Size attribute, which, as noted above, is equivalent to Value_Size).
207 -- To get a feel for the difference, consider the following examples (note
208 -- that in each case the base is short_short_integer with a size of 8):
210 -- Object_Size Value_Size
212 -- type x1 is range 0..5; 8 3
214 -- type x2 is range 0..5;
215 -- for x2'size use 12; 16 12
217 -- subtype x3 is x2 range 0 .. 3; 16 2
219 -- subtype x4 is x2'base range 0 .. 10; 8 4
221 -- dynamic : x2'Base range -64 .. +63;
223 -- subtype x5 is x2 range 0 .. dynamic; 16 3*
225 -- subtype x6 is x2'base range 0 .. dynamic; 8 7*
227 -- Note: the entries marked * are not actually specified by the Ada 95 RM,
228 -- but it seems in the spirit of the RM rules to allocate the minimum number
229 -- of bits known to be large enough to hold the given range of values.
231 -- So far, so good, but GNAT has to obey the RM rules, so the question is
232 -- under what conditions must the RM Size be used. The following is a list
233 -- of the occasions on which the RM Size must be used:
235 -- Component size for packed arrays or records
236 -- Value of the attribute Size for a type
237 -- Warning about sizes not matching for unchecked conversion
239 -- The RM_Size field keeps track of the RM Size as needed in these
242 -- For elementary types other than discrete and fixed-point types, the
243 -- Object_Size and Value_Size are the same (and equivalent to the RM
244 -- attribute Size). Only Size may be specified for such types.
246 -- For composite types, Object_Size and Value_Size are computed from their
247 -- respective value for the type of each element as well as the layout.
249 -- All size attributes are stored as Uint values. Negative values are used to
250 -- reference GCC expressions for the case of non-static sizes, as explained
253 --------------------------------------
254 -- Delayed Freezing and Elaboration --
255 --------------------------------------
257 -- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
258 -- freeze node, which appears later in the expanded tree.
260 -- a) The flag is used by the front-end to trigger expansion actions which
261 -- include the generation of that freeze node. Typically this happens at the
262 -- end of the current compilation unit, or before the first subprogram body is
263 -- encountered in the current unit. See files freeze and exp_ch13 for details
264 -- on the actions triggered by a freeze node, which include the construction
265 -- of initialization procedures and dispatch tables.
267 -- b) The presence of a freeze node on an entity is used by the backend to
268 -- defer elaboration of the entity until its freeze node is seen. In the
269 -- absence of an explicit freeze node, an entity is frozen (and elaborated)
270 -- at the point of declaration.
272 -- For object declarations, the flag is set when an address clause for the
273 -- object is encountered. Legality checks on the address expression only take
274 -- place at the freeze point of the object.
276 -- Most types have an explicit freeze node, because they cannot be elaborated
277 -- until all representation and operational items that apply to them have been
278 -- analyzed. Private types and incomplete types have the flag set as well, as
279 -- do task and protected types.
281 -- Implicit base types created for type derivations, as well as classwide
282 -- types created for all tagged types, have the flag set.
284 -- If a subprogram has an access parameter whose designated type is incomplete
285 -- the subprogram has the flag set.
287 -----------------------
288 -- Entity Attributes --
289 -----------------------
291 -- This section contains a complete list of the attributes that are defined
292 -- on entities. Some attributes apply to all entities, others only to certain
293 -- kinds of entities. In the latter case the attribute should only be set or
294 -- accessed if the Ekind field indicates an appropriate entity.
296 -- There are two kinds of attributes that apply to entities, stored and
297 -- synthesized. Stored attributes correspond to a field or flag in the entity
298 -- itself. Such attributes are identified in the table below by giving the
299 -- field or flag in the attribute that is used to hold the attribute value.
300 -- Synthesized attributes are not stored directly, but are rather computed as
301 -- needed from other attributes, or from information in the tree. These are
302 -- marked "synthesized" in the table below. The stored attributes have both
303 -- access functions and set procedures to set the corresponding values, while
304 -- synthesized attributes have only access functions.
306 -- Note: in the case of Node, Uint, or Elist fields, there are cases where the
307 -- same physical field is used for different purposes in different entities,
308 -- so these access functions should only be referenced for the class of
309 -- entities in which they are defined as being present. Flags are not
310 -- overlapped in this way, but nevertheless as a matter of style and
311 -- abstraction (which may or may not be checked by assertions in the
312 -- body), this restriction should be observed for flag fields as well.
314 -- Note: certain of the attributes on types apply only to base types, and
315 -- are so noted by the notation [base type only]. These are cases where the
316 -- attribute of any subtype is the same as the attribute of the base type.
317 -- The attribute can be referenced on a subtype (and automatically retrieves
318 -- the value from the base type). However, it is an error to try to set the
319 -- attribute on other than the base type, and if assertions are enabled,
320 -- an attempt to set the attribute on a subtype will raise an assert error.
322 -- Other attributes are noted as applying to the [implementation base type
323 -- only]. These are representation attributes which must always apply to a
324 -- full non-private type, and where the attributes are always on the full
325 -- type. The attribute can be referenced on a subtype (and automatically
326 -- retries the value from the implementation base type). However, it is an
327 -- error to try to set the attribute on other than the implementation base
328 -- type, and if assertions are enabled, an attempt to set the attribute on a
329 -- subtype will raise an assert error.
331 -- Abstract_States (Elist25)
332 -- Defined for E_Package entities. Contains a list of all the abstract
333 -- states declared by the related package.
335 -- Accept_Address (Elist21)
336 -- Defined in entries. If an accept has a statement sequence, then an
337 -- address variable is created, which is used to hold the address of the
338 -- parameters, as passed by the runtime. Accept_Address holds an element
339 -- list which represents a stack of entities for these address variables.
340 -- The current entry is the top of the stack, which is the last element
341 -- on the list. A stack is required to handle the case of nested select
342 -- statements referencing the same entry.
344 -- Access_Disp_Table (Elist16) [implementation base type only]
345 -- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged
346 -- types to point to their dispatch tables. The first two entities are
347 -- associated with the primary dispatch table: 1) primary dispatch table
348 -- with user-defined primitives 2) primary dispatch table with predefined
349 -- primitives. For each interface type covered by the tagged type we also
350 -- have: 3) secondary dispatch table with thunks of primitives covering
351 -- user-defined interface primitives, 4) secondary dispatch table with
352 -- thunks of predefined primitives, 5) secondary dispatch table with user
353 -- defined primitives, and 6) secondary dispatch table with predefined
354 -- primitives. The last entity of this list is an access type declaration
355 -- used to expand dispatching calls through the primary dispatch table.
356 -- For an untagged record, contains No_Elist.
358 -- Activation_Record_Component (Node31)
359 -- Defined in E_Variable, E_Constant, E_Loop_Parameter, E_In_Parameter,
360 -- E_Out_Parameter, E_In_Out_Parameter nodes. Used only if we are in
361 -- Opt.Unnest_Subprogram_Mode, in which case for the case of an uplevel
362 -- referenced entity, this field contains the entity for the component
363 -- in the generated ARECnT activation record (Exp_Unst for details).
365 -- Actual_Subtype (Node17)
366 -- Defined in variables, constants, and formal parameters. This is the
367 -- subtype imposed by the value of the object, as opposed to its nominal
368 -- subtype, which is imposed by the declaration. The actual subtype
369 -- differs from the nominal one when the latter is indefinite (as in the
370 -- case of an unconstrained formal parameter, or a variable declared
371 -- with an unconstrained type and an initial value). The nominal subtype
372 -- is the Etype entry for the entity. The Actual_Subtype field is set
373 -- only if the actual subtype differs from the nominal subtype. If the
374 -- actual and nominal subtypes are the same, then the Actual_Subtype
375 -- field is Empty, and Etype indicates both types.
377 -- For objects, the Actual_Subtype is set only if this is a discriminated
378 -- type. For arrays, the bounds of the expression are obtained and the
379 -- Etype of the object is directly the constrained subtype. This is
380 -- rather irregular, and the semantic checks that depend on the nominal
381 -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
383 -- Address_Clause (synthesized)
384 -- Applies to entries, objects and subprograms. Set if an address clause
385 -- is present which references the object or subprogram and points to
386 -- the N_Attribute_Definition_Clause node. Empty if no Address clause.
387 -- The expression in the address clause is always a constant that is
388 -- defined before the entity to which the address clause applies.
389 -- Note: The backend references this field in E_Task_Type entities???
391 -- Address_Taken (Flag104)
392 -- Defined in all entities. Set if the Address or Unrestricted_Access
393 -- attribute is applied directly to the entity, i.e. the entity is the
394 -- entity of the prefix of the attribute reference. Also set if the
395 -- entity is the second argument of an Asm_Input or Asm_Output attribute,
396 -- as the construct may entail taking its address. Used by the backend to
397 -- make sure that the address can be meaningfully taken, and also in the
398 -- case of subprograms to control output of certain warnings.
400 -- Aft_Value (synthesized)
401 -- Applies to fixed and decimal types. Computes a universal integer that
402 -- holds value of the Aft attribute for the type.
405 -- Defined in overloadable entities (literals, subprograms, entries) and
406 -- subprograms that cover a primitive operation of an abstract interface
407 -- (that is, subprograms with the Interface_Alias attribute). In case of
408 -- overloaded entities it points to the parent subprogram of a derived
409 -- subprogram. In case of abstract interface subprograms it points to the
410 -- subprogram that covers the abstract interface primitive. Also used for
411 -- a subprogram renaming, where it points to the renamed subprogram. For
412 -- an inherited operation (of a type extension) that is overridden in a
413 -- private part, the Alias is the overriding operation. In this fashion a
414 -- call from outside the package ends up executing the new body even if
415 -- non-dispatching, and a call from inside calls the overriding operation
416 -- because it hides the implicit one. Alias is always empty for entries.
418 -- Alignment (Uint14)
419 -- Defined in entities for types and also in constants, variables
420 -- (including exceptions where it refers to the static data allocated for
421 -- an exception), loop parameters, and formal parameters. This indicates
422 -- the desired alignment for a type, or the actual alignment for an
423 -- object. A value of zero (Uint_0) indicates that the alignment has not
424 -- been set yet. The alignment can be set by an explicit alignment
425 -- clause, or set by the front-end in package Layout, or set by the
426 -- back-end as part of the back-end back-annotation process. The
427 -- alignment field is also defined in E_Exception entities, but there it
428 -- is used only by the back-end for back annotation.
430 -- Alignment_Clause (synthesized)
431 -- Applies to all entities for types and objects. If an alignment
432 -- attribute definition clause is present for the entity, then this
433 -- function returns the N_Attribute_Definition clause that specifies the
434 -- alignment. If no alignment clause applies to the type, then the call
435 -- to this function returns Empty. Note that the call can return a
436 -- non-Empty value even if Has_Alignment_Clause is not set (happens with
437 -- subtype and derived type declarations). Note also that a record
438 -- definition clause with an (obsolescent) mod clause is converted
439 -- into an attribute definition clause for this purpose.
441 -- Anonymous_Master (Node36)
442 -- Defined in the entities of non-generic packages, subprograms and their
443 -- corresponding bodies. Contains the entity of a special heterogeneous
444 -- finalization master that services most anonymous access-to-controlled
445 -- allocations that occur within the unit.
447 -- Associated_Entity (Node37)
448 -- Defined in all entities. This field is similar to Associated_Node, but
449 -- applied to entities. The attribute links an entity from the generic
450 -- template with its corresponding entity in the analyzed generic copy.
451 -- The global references mechanism relies on the Associated_Entity to
452 -- infer the context.
454 -- Associated_Formal_Package (Node12)
455 -- Defined in packages that are the actuals of formal_packages. Points
456 -- to the entity in the declaration for the formal package.
458 -- Associated_Node_For_Itype (Node8)
459 -- Defined in all type and subtype entities. Set non-Empty only for
460 -- Itypes. Set to point to the associated node for the Itype, i.e.
461 -- the node whose elaboration generated the Itype. This is used for
462 -- copying trees, to determine whether or not to copy an Itype, and
463 -- also for accessibility checks on anonymous access types. This
464 -- node is typically an object declaration, component declaration,
465 -- type or subtype declaration. For an access discriminant in a type
466 -- declaration, the associated_node_for_itype is the discriminant
467 -- specification. For an access parameter it is the enclosing subprogram
470 -- Itypes have no explicit declaration, and therefore are not attached to
471 -- the tree: their Parent field is always empty. The Associated_Node_For_
472 -- Itype is the only way to determine the construct that leads to the
473 -- creation of a given itype entity.
475 -- Associated_Storage_Pool (Node22) [root type only]
476 -- Defined in simple and general access type entities. References the
477 -- storage pool to be used for the corresponding collection. A value of
478 -- Empty means that the default pool is to be used. This is defined
479 -- only in the root type, since derived types must have the same pool
480 -- as the parent type.
482 -- Barrier_Function (Node12)
483 -- Defined in protected entries and entry families. This is the
484 -- subprogram declaration for the body of the function that returns
485 -- the value of the entry barrier.
487 -- Base_Type (synthesized)
488 -- Applies to all type and subtype entities. Returns the base type of a
489 -- type or subtype. The base type of a type is the type itself. The base
490 -- type of a subtype is the type that it constrains (which is always
491 -- a type entity, not some other subtype). Note that in the case of a
492 -- subtype of a private type, it is possible for the base type attribute
493 -- to return a private type, even if the subtype to which it applies is
494 -- non-private. See also Implementation_Base_Type. Note: it is allowed to
495 -- apply Base_Type to other than a type, in which case it simply returns
496 -- the entity unchanged.
498 -- Block_Node (Node11)
499 -- Defined in block entities. Points to the identifier in the
500 -- Block_Statement itself. Used when retrieving the block construct
501 -- for finalization purposes, The block entity has an implicit label
502 -- declaration in the enclosing declarative part, and has otherwise
503 -- no direct connection in the tree with the block statement. The
504 -- link is to the identifier (which is an occurrence of the entity)
505 -- and not to the block_statement itself, because the statement may
506 -- be rewritten, e.g. in the process of removing dead code.
508 -- Body_Entity (Node19)
509 -- Defined in package and generic package entities, points to the
510 -- corresponding package body entity if one is present.
512 -- Body_Needed_For_SAL (Flag40)
513 -- Defined in package and subprogram entities that are compilation
514 -- units. Indicates that the source for the body must be included
515 -- when the unit is part of a standalone library.
517 -- Body_References (Elist16)
518 -- Defined in abstract state entities. Contains an element list of
519 -- references (identifiers) that appear in a package body whose spec
520 -- defines the related state. If the body refines the said state, all
521 -- references on this list are illegal due to the visible refinement.
523 -- BIP_Initialization_Call (Node29)
524 -- Defined in constants and variables whose corresponding declaration
525 -- is wrapped in a transient block and the inital value is provided by
526 -- a build-in-place function call. Contains the relocated build-in-place
527 -- call after the expansion has decoupled the call from the object. This
528 -- attribute is used by the finalization machinery to insert cleanup code
529 -- for all additional transient variables found in the transient block.
531 -- C_Pass_By_Copy (Flag125) [implementation base type only]
532 -- Defined in record types. Set if a pragma Convention for the record
533 -- type specifies convention C_Pass_By_Copy. This convention name is
534 -- treated as identical in all respects to convention C, except that
535 -- if it is specified for a record type, then the C_Pass_By_Copy flag
536 -- is set, and if a foreign convention subprogram has a formal of the
537 -- corresponding type, then the parameter passing mechanism will be
538 -- set to By_Copy (unless specifically overridden by an Import or
541 -- Can_Never_Be_Null (Flag38)
542 -- This flag is defined in all entities. It is set in an object which can
543 -- never have a null value. Set for constant access values initialized to
544 -- a non-null value. This is also set for all access parameters in Ada 83
545 -- and Ada 95 modes, and for access parameters that explicitly exclude
546 -- exclude null in Ada 2005 mode.
548 -- This is used to avoid unnecessary resetting of the Is_Known_Non_Null
549 -- flag for such entities. In Ada 2005 mode, this is also used when
550 -- determining subtype conformance of subprogram profiles to ensure
551 -- that two formals have the same null-exclusion status.
553 -- This is also set on some access types, e.g. the Etype of the anonymous
554 -- access type of a controlling formal.
556 -- Can_Use_Internal_Rep (Flag229) [base type only]
557 -- Defined in Access_Subprogram_Kind nodes. This flag is set by the
558 -- front end and used by the backend. False means that the backend
559 -- must represent the type in the same way as Convention-C types (and
560 -- other foreign-convention types). On many targets, this means that
561 -- the backend will use dynamically generated trampolines for nested
562 -- subprograms. True means that the backend can represent the type in
563 -- some internal way. On the aforementioned targets, this means that the
564 -- backend will not use dynamically generated trampolines. This flag
565 -- must be False if Has_Foreign_Convention is True; otherwise, the front
566 -- end is free to set the policy.
568 -- Setting this False in all cases corresponds to the traditional back
569 -- end strategy, where all access-to-subprogram types are represented the
570 -- same way, independent of the Convention. For further details, see also
571 -- Always_Compatible_Rep in Targparm.
573 -- Efficiency note: On targets that use dynamically generated
574 -- trampolines, False generally favors efficiency of top-level
575 -- subprograms, whereas True generally favors efficiency of nested
576 -- ones. On other targets, this flag has little or no effect on
577 -- efficiency. The front end should take this into account. In
578 -- particular, pragma Favor_Top_Level gives a hint that the flag
581 -- Note: We considered using Convention-C for this purpose, but we need
582 -- this separate flag, because Convention-C implies that in the case of
583 -- P'[Unrestricted_]Access, P also have convention C. Sometimes we want
584 -- to have Can_Use_Internal_Rep False for an access type, but allow P to
585 -- have convention Ada.
588 -- Defined in all entities. This field contains an entry into the names
589 -- table that has the character string of the identifier, character
590 -- literal or operator symbol. See Namet for further details. Note that
591 -- throughout the processing of the front end, this name is the simple
592 -- unqualified name. However, just before the backend is called, a call
593 -- is made to Qualify_All_Entity_Names. This causes entity names to be
594 -- qualified using the encoding described in exp_dbug.ads, and from that
595 -- point (including post backend steps, e.g. cross-reference generation),
596 -- the entities will contain the encoded qualified names.
598 -- Checks_May_Be_Suppressed (Flag31)
599 -- Defined in all entities. Set if a pragma Suppress or Unsuppress
600 -- mentions the entity specifically in the second argument. If this
601 -- flag is set the Global_Entity_Suppress and Local_Entity_Suppress
602 -- tables must be consulted to determine if there actually is an active
603 -- Suppress or Unsuppress pragma that applies to the entity.
605 -- Class_Wide_Type (Node9)
606 -- Defined in all type entities. For a tagged type or subtype, returns
607 -- the corresponding implicitly declared class-wide type. For a
608 -- class-wide type, returns itself. Set to Empty for untagged types.
610 -- Cloned_Subtype (Node16)
611 -- Defined in E_Record_Subtype and E_Class_Wide_Subtype entities.
612 -- Each such entity can either have a Discriminant_Constraint, in
613 -- which case it represents a distinct type from the base type (and
614 -- will have a list of components and discrimants in the list headed by
615 -- First_Entity) or else no such constraint, in which case it will be a
616 -- copy of the base type.
618 -- o Each element of the list in First_Entity is copied from the base
619 -- type; in that case, this field is Empty.
621 -- o The list in First_Entity is shared with the base type; in that
622 -- case, this field points to that entity.
624 -- A record or classwide subtype may also be a copy of some other
625 -- subtype and share the entities in the First_Entity with that subtype.
626 -- In that case, this field points to that subtype.
628 -- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
629 -- this field. Note that this field ONLY appears in subtype entries, not
630 -- in type entries, it is not defined, and it is an error to reference
631 -- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
634 -- This flag appears on all nodes, including entities, and indicates
635 -- that the node was created by the scanner or parser from the original
636 -- source. Thus for entities, it indicates that the entity is defined
637 -- in the original source program.
639 -- Component_Alignment (special field) [base type only]
640 -- Defined in array and record entities. Contains a value of type
641 -- Component_Alignment_Kind indicating the alignment of components.
642 -- Set to Calign_Default normally, but can be overridden by use of
643 -- the Component_Alignment pragma. Note: this field is currently
644 -- stored in a non-standard way, see body for details.
646 -- Component_Bit_Offset (Uint11)
647 -- Defined in record components (E_Component, E_Discriminant) if a
648 -- component clause applies to the component. First bit position of
649 -- given component, computed from the first bit and position values
650 -- given in the component clause. A value of No_Uint means that the
651 -- value is not yet known. The value can be set by the appearance of
652 -- an explicit component clause in a record representation clause,
653 -- or it can be set by the front-end in package Layout, or it can be
654 -- set by the backend. By the time backend processing is completed,
655 -- this field is always set. A negative value is used to represent
656 -- a value which is not known at compile time, and must be computed
657 -- at run-time (this happens if fields of a record have variable
658 -- lengths). See package Layout for details of these values.
660 -- Note: Component_Bit_Offset is redundant with respect to the fields
661 -- Normalized_First_Bit and Normalized_Position, and could in principle
662 -- be eliminated, but it is convenient in several situations, including
663 -- use in the backend, to have this redundant field.
665 -- Component_Clause (Node13)
666 -- Defined in record components and discriminants. If a record
667 -- representation clause is present for the corresponding record type a
668 -- that specifies a position for the component, then the Component_Clause
669 -- field of the E_Component entity points to the N_Component_Clause node.
670 -- Set to Empty if no record representation clause was present, or if
671 -- there was no specification for this component.
673 -- Component_Size (Uint22) [implementation base type only]
674 -- Defined in array types. It contains the component size value for
675 -- the array. A value of No_Uint means that the value is not yet set.
676 -- The value can be set by the use of a component size clause, or
677 -- by the front end in package Layout, or by the backend. A negative
678 -- value is used to represent a value which is not known at compile
679 -- time, and must be computed at run-time (this happens if the type
680 -- of the component has a variable length size). See package Layout
681 -- for details of these values.
683 -- Component_Type (Node20) [implementation base type only]
684 -- Defined in array types and string types. References component type.
686 -- Contains_Ignored_Ghost_Code (Flag279)
687 -- Defined in blocks, packages and their bodies, subprograms and their
688 -- bodies. Set if the entity contains any ignored Ghost code in the form
689 -- of declaration, procedure call, assignment statement or pragma.
691 -- Corresponding_Concurrent_Type (Node18)
692 -- Defined in record types that are constructed by the expander to
693 -- represent task and protected types (Is_Concurrent_Record_Type flag
694 -- set). Points to the entity for the corresponding task type or the
697 -- Corresponding_Discriminant (Node19)
698 -- Defined in discriminants of a derived type, when the discriminant is
699 -- used to constrain a discriminant of the parent type. Points to the
700 -- corresponding discriminant in the parent type. Otherwise it is Empty.
702 -- Corresponding_Equality (Node30)
703 -- Defined in function entities for implicit inequality operators.
704 -- Denotes the explicit or derived equality operation that creates
705 -- the implicit inequality. Note that this field is not present in
706 -- other function entities, only in implicit inequality routines,
707 -- where Comes_From_Source is always False.
709 -- Corresponding_Protected_Entry (Node18)
710 -- Defined in subprogram bodies. Set for subprogram bodies that implement
711 -- a protected type entry to point to the entity for the entry.
713 -- Corresponding_Record_Type (Node18)
714 -- Defined in protected and task types and subtypes. References the
715 -- entity for the corresponding record type constructed by the expander
716 -- (see Exp_Ch9). This type is used to represent values of the task type.
718 -- Corresponding_Remote_Type (Node22)
719 -- Defined in record types that describe the fat pointer structure for
720 -- Remote_Access_To_Subprogram types. References the original access
721 -- to subprogram type.
723 -- CR_Discriminant (Node23)
724 -- Defined in discriminants of concurrent types. Denotes the homologous
725 -- discriminant of the corresponding record type. The CR_Discriminant is
726 -- created at the same time as the discriminal, and used to replace
727 -- occurrences of the discriminant within the type declaration.
729 -- Current_Use_Clause (Node27)
730 -- Defined in packages and in types. For packages, denotes the use
731 -- package clause currently in scope that makes the package use_visible.
732 -- For types, it denotes the use_type clause that makes the operators of
733 -- the type visible. Used for more precise warning messages on redundant
736 -- Current_Value (Node9)
737 -- Defined in all object entities. Set in E_Variable, E_Constant, formal
738 -- parameters and E_Loop_Parameter entities if we have trackable current
739 -- values. Set non-Empty if the (constant) current value of the variable
740 -- is known, This value is valid only for references from the same
741 -- sequential scope as the entity. The sequential scope of an entity
742 -- includes the immediate scope and any contained scopes that are package
743 -- specs, package bodies, blocks (at any nesting level) or statement
744 -- sequences in IF or loop statements.
746 -- Another related use of this field is to record information about the
747 -- value obtained from an IF or WHILE statement condition. If the IF or
748 -- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ",
749 -- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a
750 -- Current_Value field, RELOP is one of the six relational operators, and
751 -- VAL is a compile-time known value then the Current_Value field of OBJ
752 -- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node
753 -- of the relevant construct, and the Condition field of this can be
754 -- consulted to give information about the value of OBJ. For more details
755 -- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition.
757 -- Debug_Info_Off (Flag166)
758 -- Defined in all entities. Set if a pragma Suppress_Debug_Info applies
759 -- to the entity, or if internal processing in the compiler determines
760 -- that suppression of debug information is desirable. Note that this
761 -- flag is only for use by the front end as part of the processing for
762 -- determining if Needs_Debug_Info should be set. The backend should
763 -- always test Needs_Debug_Info, it should never test Debug_Info_Off.
765 -- Debug_Renaming_Link (Node25)
766 -- Used to link the variable associated with a debug renaming declaration
767 -- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
768 -- details of the use of this field.
770 -- Declaration_Node (synthesized)
771 -- Applies to all entities. Returns the tree node for the construct that
772 -- declared the entity. Normally this is just the Parent of the entity.
773 -- One exception arises with child units, where the parent of the entity
774 -- is a selected component/defining program unit name. Another exception
775 -- is that if the entity is an incomplete type that has been completed or
776 -- a private type, then we obtain the declaration node denoted by the
777 -- full type, i.e. the full type declaration node. Also note that for
778 -- subprograms, this returns the {function,procedure}_specification, not
779 -- the subprogram_declaration.
781 -- Default_Aspect_Component_Value (Node19) [base type only]
782 -- Defined in array types. Holds the static value specified in a
783 -- Default_Component_Value aspect specification for the array type,
784 -- or inherited on derivation.
786 -- Default_Aspect_Value (Node19) [base type only]
787 -- Defined in scalar types. Holds the static value specified in a
788 -- Default_Value aspect specification for the type, or inherited
791 -- Default_Expr_Function (Node21)
792 -- Defined in parameters. It holds the entity of the parameterless
793 -- function that is built to evaluate the default expression if it is
794 -- more complex than a simple identifier or literal. For the latter
795 -- simple cases or if there is no default value, this field is Empty.
797 -- Default_Expressions_Processed (Flag108)
798 -- A flag in subprograms (functions, operators, procedures) and in
799 -- entries and entry families used to indicate that default expressions
800 -- have been processed and to avoid multiple calls to process the
801 -- default expressions (see Freeze.Process_Default_Expressions), which
802 -- would not only waste time, but also generate false error messages.
804 -- Default_Init_Cond_Procedure (synthesized)
805 -- Defined in all types. Set for private [sub]types subject to pragma
806 -- Default_Initial_Condition, their corresponding full views and derived
807 -- types with at least one parent subject to the pragma. Contains the
808 -- entity of the procedure which takes a single argument of the given
809 -- type and verifies the assumption of the pragma.
811 -- Note: the reason this is marked as a synthesized attribute is that the
812 -- way this is stored is as an element of the Subprograms_For_Type field.
814 -- Default_Value (Node20)
815 -- Defined in formal parameters. Points to the node representing the
816 -- expression for the default value for the parameter. Empty if the
817 -- parameter has no default value (which is always the case for OUT
818 -- and IN OUT parameters in the absence of errors).
820 -- Delay_Cleanups (Flag114)
821 -- Defined in entities that have finalization lists (subprograms
822 -- blocks, and tasks). Set if there are pending generic body
823 -- instantiations for the corresponding entity. If this flag is
824 -- set, then generation of cleanup actions for the corresponding
825 -- entity must be delayed, since the insertion of the generic body
826 -- may affect cleanup generation (see Inline for further details).
828 -- Delay_Subprogram_Descriptors (Flag50)
829 -- Defined in entities for which exception subprogram descriptors
830 -- are generated (subprograms, package declarations and package
831 -- bodies). Defined if there are pending generic body instantiations
832 -- for the corresponding entity. If this flag is set, then generation
833 -- of the subprogram descriptor for the corresponding enities must
834 -- be delayed, since the insertion of the generic body may add entries
835 -- to the list of handlers.
837 -- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
838 -- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
839 -- a block (in which case Delay_Subprogram_Descriptors is set for the
840 -- containing subprogram). In addition Delay_Subprogram_Descriptors is
841 -- set for a library level package declaration or body which contains
842 -- delayed instantiations (in this case the descriptor refers to the
843 -- enclosing elaboration procedure).
845 -- Delta_Value (Ureal18)
846 -- Defined in fixed and decimal types. Points to a universal real
847 -- that holds value of delta for the type, as given in the declaration
848 -- or as inherited by a subtype or derived type.
850 -- Dependent_Instances (Elist8)
851 -- Defined in packages that are instances. Holds list of instances
852 -- of inner generics. Used to place freeze nodes for those instances
853 -- after that of the current one, i.e. after the corresponding generic
856 -- Depends_On_Private (Flag14)
857 -- Defined in all type entities. Set if the type is private or if it
858 -- depends on a private type.
860 -- Derived_Type_Link (Node31)
861 -- Defined in all type and subtype entries. Set in a base type if
862 -- a derived type declaration is encountered which derives from
863 -- this base type or one of its subtypes, and there are already
864 -- primitive operations declared. In this case, it references the
865 -- entity for the type declared by the derived type declaration.
869 -- subtype RS is R ...
871 -- type G is new RS ...
873 -- In this case, if primitive operations have been declared for R, at
874 -- the point of declaration of G, then the Derived_Type_Link of R is set
875 -- to point to the entity for G. This is used to generate warnings for
876 -- rep clauses that appear later on for R, which might result in an
877 -- unexpected implicit conversion operation.
879 -- Note: if there is more than one such derived type, the link will point
880 -- to the last one (this is only used in generating warning messages).
882 -- Designated_Type (synthesized)
883 -- Applies to access types. Returns the designated type. Differs from
884 -- Directly_Designated_Type in that if the access type refers to an
885 -- incomplete type, and the full type is available, then this full type
886 -- is returned instead of the incomplete type.
888 -- Digits_Value (Uint17)
889 -- Defined in floating point types and subtypes and decimal types and
890 -- subtypes. Contains the Digits value specified in the declaration.
892 -- Direct_Primitive_Operations (Elist10)
893 -- Defined in tagged types and subtypes (including synchronized types),
894 -- in tagged private types and in tagged incomplete types. Element list
895 -- of entities for primitive operations of the tagged type. Not defined
896 -- in untagged types. In order to follow the C++ ABI, entities of
897 -- primitives that come from source must be stored in this list in the
898 -- order of their occurrence in the sources. For incomplete types the
899 -- list is always empty.
900 -- When expansion is disabled the corresponding record type of a
901 -- synchronized type is not constructed. In that case, such types
902 -- carry this attribute directly, for ASIS use.
904 -- Directly_Designated_Type (Node20)
905 -- Defined in access types. This field points to the type that is
906 -- directly designated by the access type. In the case of an access
907 -- type to an incomplete type, this field references the incomplete
908 -- type. Directly_Designated_Type is typically used in implementing the
909 -- static semantics of the language; in implementing dynamic semantics,
910 -- we typically want the full view of the designated type. The function
911 -- Designated_Type obtains this full type in the case of access to an
914 -- Disable_Controlled (Flag253)
915 -- Present in all entities. Set for a controlled type (Is_Controlled flag
916 -- set) if the aspect Disable_Controlled is active for the type.
918 -- Discard_Names (Flag88)
919 -- Defined in types and exception entities. Set if pragma Discard_Names
920 -- applies to the entity. It is also set for declarative regions and
921 -- package specs for which a Discard_Names pragma with zero arguments
922 -- has been encountered. The purpose of setting this flag is to be able
923 -- to set the Discard_Names attribute on enumeration types declared
924 -- after the pragma within the same declarative region. This flag is
925 -- set to False if a Keep_Names pragma appears for an enumeration type.
927 -- Discriminal (Node17)
928 -- Defined in discriminants (Discriminant formal: GNAT's first
929 -- coinage). The entity used as a formal parameter that corresponds
930 -- to a discriminant. See section "Handling of Discriminants" for
931 -- full details of the use of discriminals.
933 -- Discriminal_Link (Node10)
934 -- Defined in E_In_Parameter or E_Constant entities. For discriminals,
935 -- points back to corresponding discriminant. For other entities, must
938 -- Discriminant_Checking_Func (Node20)
939 -- Defined in components. Points to the defining identifier of the
940 -- function built by the expander returns a Boolean indicating whether
941 -- the given record component exists for the current discriminant
944 -- Discriminant_Constraint (Elist21)
945 -- Defined in entities whose Has_Discriminants flag is set (concurrent
946 -- types, subtypes, record types and subtypes, private types and
947 -- subtypes, limited private types and subtypes and incomplete types).
948 -- It is an error to reference the Discriminant_Constraint field if
949 -- Has_Discriminants is False.
951 -- If the Is_Constrained flag is set, Discriminant_Constraint points
952 -- to an element list containing the discriminant constraints in the
953 -- same order in which the discriminants are declared.
955 -- If the Is_Constrained flag is not set but the discriminants of the
956 -- unconstrained type have default initial values then this field
957 -- points to an element list giving these default initial values in
958 -- the same order in which the discriminants are declared. Note that
959 -- in this case the entity cannot be a tagged record type, because
960 -- discriminants in this case cannot have defaults.
962 -- If the entity is a tagged record implicit type, then this field is
963 -- inherited from the first subtype (so that the itype is subtype
964 -- conformant with its first subtype, which is needed when the first
965 -- subtype overrides primitive operations inherited by the implicit
968 -- In all other cases Discriminant_Constraint contains the empty
969 -- Elist (ie it is initialized with a call to New_Elmt_List).
971 -- Discriminant_Default_Value (Node20)
972 -- Defined in discriminants. Points to the node representing the
973 -- expression for the default value of the discriminant. Set to
974 -- Empty if the discriminant has no default value.
976 -- Discriminant_Number (Uint15)
977 -- Defined in discriminants. Gives the ranking of a discriminant in
978 -- the list of discriminants of the type, i.e. a sequential integer
979 -- index starting at 1 and ranging up to number of discriminants.
981 -- Dispatch_Table_Wrappers (Elist26) [implementation base type only]
982 -- Defined in E_Record_Type and E_Record_Subtype entities. Set in library
983 -- level tagged type entities if we are generating statically allocated
984 -- dispatch tables. Points to the list of dispatch table wrappers
985 -- associated with the tagged type. For an untagged record, contains
988 -- DTC_Entity (Node16)
989 -- Defined in function and procedure entities. Set to Empty unless
990 -- the subprogram is dispatching in which case it references the
991 -- Dispatch Table pointer Component. For regular Ada tagged this, this
992 -- is the _Tag component. For CPP_Class types and their descendants,
993 -- this points to the component entity in the record that holds the
994 -- Vtable pointer for the Vtable containing the entry referencing the
997 -- DT_Entry_Count (Uint15)
998 -- Defined in E_Component entities. Only used for component marked
999 -- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
1001 -- DT_Offset_To_Top_Func (Node25)
1002 -- Defined in E_Component entities. Only used for component marked
1003 -- Is_Tag. If present it stores the Offset_To_Top function used to
1004 -- provide this value in tagged types whose ancestor has discriminants.
1006 -- DT_Position (Uint15)
1007 -- Defined in function and procedure entities which are dispatching
1008 -- (should not be referenced without first checking that flag
1009 -- Is_Dispatching_Operation is True). Contains the offset into
1010 -- the Vtable for the entry that references the subprogram.
1013 -- Defined in all entities. Contains a value of the enumeration type
1014 -- Entity_Kind declared in a subsequent section in this spec.
1016 -- Elaborate_Body_Desirable (Flag210)
1017 -- Defined in package entities. Set if the elaboration circuitry detects
1018 -- a case where there is a package body that modifies one or more visible
1019 -- entities in the package spec and there is no explicit Elaborate_Body
1020 -- pragma for the package. This information is passed on to the binder,
1021 -- which attempts, but does not promise, to elaborate the body as close
1022 -- to the spec as possible.
1024 -- Elaboration_Entity (Node13)
1025 -- Defined in generic and non-generic package and subprogram entities.
1026 -- This is a counter associated with the unit that is initially set to
1027 -- zero, is incremented when an elaboration request for the unit is
1028 -- made, and is decremented when a finalization request for the unit
1029 -- is made. This is used for three purposes. First, it is used to
1030 -- implement access before elaboration checks (the counter must be
1031 -- non-zero to call a subprogram at elaboration time). Second, it is
1032 -- used to guard against repeated execution of the elaboration code.
1033 -- Third, it is used to ensure that the finalization code is executed
1034 -- only after all clients have requested it.
1036 -- Note that we always allocate this counter, and set this field, but
1037 -- we do not always actually use it. It is only used if it is needed
1038 -- for access before elaboration use (see Elaboration_Entity_Required
1039 -- flag) or if either the spec or the body has elaboration code. If
1040 -- neither of these two conditions holds, then the entity is still
1041 -- allocated (since we don't know early enough whether or not there
1042 -- is elaboration code), but is simply not used for any purpose.
1044 -- Elaboration_Entity_Required (Flag174)
1045 -- Defined in generic and non-generic package and subprogram entities.
1046 -- Set only if Elaboration_Entity is non-Empty to indicate that the
1047 -- counter is required to be non-zero even if there is no other
1048 -- elaboration code. This occurs when the Elaboration_Entity counter
1049 -- is used for access before elaboration checks. If the counter is
1050 -- only used to prevent multiple execution of the elaboration code,
1051 -- then if there is no other elaboration code, obviously there is no
1052 -- need to set the flag.
1054 -- Encapsulating_State (Node32)
1055 -- Defined in abstract states, constants and variables. Contains the
1056 -- entity of an ancestor state whose refinement utilizes this item as
1059 -- Enclosing_Scope (Node18)
1060 -- Defined in labels. Denotes the innermost enclosing construct that
1061 -- contains the label. Identical to the scope of the label, except for
1062 -- labels declared in the body of an accept statement, in which case the
1063 -- entry_name is the Enclosing_Scope. Used to validate goto's within
1064 -- accept statements.
1066 -- Entry_Accepted (Flag152)
1067 -- Defined in E_Entry and E_Entry_Family entities. Set if there is
1068 -- at least one accept for this entry in the task body. Used to
1069 -- generate warnings for missing accepts.
1071 -- Entry_Bodies_Array (Node19)
1072 -- Defined in protected types for which Has_Entries is true.
1073 -- This is the defining identifier for the array of entry body
1074 -- action procedures and barrier functions used by the runtime to
1075 -- execute the user code associated with each entry.
1077 -- Entry_Cancel_Parameter (Node23)
1078 -- Defined in blocks. This only applies to a block statement for
1079 -- which the Is_Asynchronous_Call_Block flag is set. It
1080 -- contains the defining identifier of an object that must be
1081 -- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
1082 -- call in the cleanup handler added to the block by
1083 -- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
1084 -- object for task entry calls and a Communications_Block object
1085 -- in the case of protected entry calls. In both cases the objects
1086 -- are declared in outer scopes to this block.
1088 -- Entry_Component (Node11)
1089 -- Defined in formal parameters (in, in out and out parameters). Used
1090 -- only for formals of entries. References the corresponding component
1091 -- of the entry parameter record for the entry.
1093 -- Entry_Formal (Node16)
1094 -- Defined in components of the record built to correspond to entry
1095 -- parameters. This field points from the component to the formal. It
1096 -- is the back pointer corresponding to Entry_Component.
1098 -- Entry_Index_Constant (Node18)
1099 -- Defined in an entry index parameter. This is an identifier that
1100 -- eventually becomes the name of a constant representing the index
1101 -- of the entry family member whose entry body is being executed. Used
1102 -- to expand references to the entry index specification identifier.
1104 -- Entry_Index_Type (synthesized)
1105 -- Applies to an entry family. Denotes Etype of the subtype indication
1106 -- in the entry declaration. Used to resolve the index expression in an
1107 -- accept statement for a member of the family, and in the prefix of
1108 -- 'COUNT when it applies to a family member.
1110 -- Contract (Node34)
1111 -- Defined in constant, entry, entry family, [generic] package, package
1112 -- body, [generic] subprogram, subprogram body, and variable entities.
1113 -- Points to the contract of the entity, holding various assertion items
1114 -- and data classifiers.
1116 -- Entry_Parameters_Type (Node15)
1117 -- Defined in entries. Points to the access-to-record type that is
1118 -- constructed by the expander to hold a reference to the parameter
1119 -- values. This reference is manipulated (as an address) by the
1120 -- tasking runtime. The designated record represents a packaging
1121 -- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
1122 -- for further details). Entry_Parameters_Type is Empty if the entry
1123 -- has no parameters.
1125 -- Enumeration_Pos (Uint11)
1126 -- Defined in enumeration literals. Contains the position number
1127 -- corresponding to the value of the enumeration literal.
1129 -- Enumeration_Rep (Uint12)
1130 -- Defined in enumeration literals. Contains the representation that
1131 -- corresponds to the value of the enumeration literal. Note that
1132 -- this is normally the same as Enumeration_Pos except in the presence
1133 -- of representation clauses, where Pos will still represent the
1134 -- position of the literal within the type and Rep will have be the
1135 -- value given in the representation clause.
1137 -- Enumeration_Rep_Expr (Node22)
1138 -- Defined in enumeration literals. Points to the expression in an
1139 -- associated enumeration rep clause that provides the representation
1140 -- value for this literal. Empty if no enumeration rep clause for this
1141 -- literal (or if rep clause does not have an entry for this literal,
1142 -- an error situation). This is also used to catch duplicate entries
1143 -- for the same literal.
1145 -- Enum_Pos_To_Rep (Node23)
1146 -- Defined in enumeration types (but not enumeration subtypes). Set to
1147 -- Empty unless the enumeration type has a non-standard representation
1148 -- (i.e. at least one literal has a representation value different from
1149 -- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
1150 -- array constructed when the type is frozen that maps Pos values to
1151 -- corresponding Rep values. The index type of this array is Natural,
1152 -- and the component type is a suitable integer type that holds the
1153 -- full range of representation values.
1155 -- Equivalent_Type (Node18)
1156 -- Defined in class wide types and subtypes, access to protected
1157 -- subprogram types, and in exception types. For a classwide type, it
1158 -- is always Empty. For a class wide subtype, it points to an entity
1159 -- created by the expander which gives the backend an understandable
1160 -- equivalent of the class subtype with a known size (given by an
1161 -- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
1162 -- details. For E_Exception_Type, this points to the record containing
1163 -- the data necessary to represent exceptions (for further details, see
1164 -- System.Standard_Library. For access_to_protected subprograms, it
1165 -- denotes a record that holds pointers to the operation and to the
1166 -- protected object. For remote Access_To_Subprogram types, it denotes
1167 -- the record that is the fat pointer representation of an RAST.
1170 -- Defined in all types and subtypes, and also for components, constants,
1171 -- and variables, including exceptions where it refers to the static data
1172 -- allocated for an exception. Contains the Object_Size of the type or of
1173 -- the object. A value of zero indicates that the value is not yet known.
1175 -- For the case of components where a component clause is present, the
1176 -- value is the value from the component clause, which must be non-
1177 -- negative (but may be zero, which is acceptable for the case of
1178 -- a type with only one possible value). It is also possible for Esize
1179 -- of a component to be set without a component clause defined, which
1180 -- means that the component size is specified, but not the position.
1181 -- See also RM_Size and the section on "Handling of Type'Size Values".
1182 -- During backend processing, the value is back annotated for all zero
1183 -- values, so that after the call to the backend, the value is set.
1186 -- Defined in all entities. Represents the type of the entity, which
1187 -- is itself another entity. For a type entity, points to the parent
1188 -- type for a derived type, or if the type is not derived, points to
1189 -- itself. For a subtype entity, Etype points to the base type. For
1190 -- a class wide type, points to the corresponding specific type. For a
1191 -- subprogram or subprogram type, Etype has the return type of a function
1192 -- or is set to Standard_Void_Type to represent a procedure. The Etype
1193 -- field of a package is also set to Standard_Void_Type.
1195 -- Note one obscure case: for pragma Default_Storage_Pool (null), the
1196 -- Etype of the N_Null node is Empty.
1198 -- Extra_Accessibility (Node13)
1199 -- Defined in formal parameters in the non-generic case. Normally Empty,
1200 -- but if expansion is active, and a parameter is one for which a
1201 -- dynamic accessibility check is required, then an extra formal of type
1202 -- Natural is created (see description of field Extra_Formal), and the
1203 -- Extra_Accessibility field of the formal parameter points to the entity
1204 -- for this extra formal. Also defined in variables when compiling
1205 -- receiving stubs. In this case, a non Empty value means that this
1206 -- variable's accessibility depth has been transmitted by the caller and
1207 -- must be retrieved through the entity designed by this field instead of
1210 -- Extra_Accessibility_Of_Result (Node19)
1211 -- Defined in (non-generic) Function, Operator, and Subprogram_Type
1212 -- entities. Normally Empty, but if expansion is active, and a function
1213 -- is one for which "the accessibility level of the result ... determined
1214 -- by the point of call" (AI05-0234) is needed, then an extra formal of
1215 -- subtype Natural is created (see description of field Extra_Formal),
1216 -- and the Extra_Accessibility_Of_Result field of the function points to
1217 -- the entity for this extra formal.
1219 -- Extra_Constrained (Node23)
1220 -- Defined in formal parameters in the non-generic case. Normally Empty,
1221 -- but if expansion is active and a parameter is one for which a dynamic
1222 -- indication of its constrained status is required, then an extra formal
1223 -- of type Boolean is created (see description of field Extra_Formal),
1224 -- and the Extra_Constrained field of the formal parameter points to the
1225 -- entity for this extra formal. Also defined in variables when compiling
1226 -- receiving stubs. In this case, a non empty value means that this
1227 -- variable's constrained status has been transmitted by the caller and
1228 -- must be retrieved through the entity designed by this field instead of
1231 -- Extra_Formal (Node15)
1232 -- Defined in formal parameters in the non-generic case. Certain
1233 -- parameters require extra implicit information to be passed (e.g. the
1234 -- flag indicating if an unconstrained variant record argument is
1235 -- constrained, and the accessibility level for access parameters). See
1236 -- description of Extra_Constrained, Extra_Accessibility fields for
1237 -- further details. Extra formal parameters are constructed to represent
1238 -- these values, and chained to the end of the list of formals using the
1239 -- Extra_Formal field (i.e. the Extra_Formal field of the last "real"
1240 -- formal points to the first extra formal, and the Extra_Formal field of
1241 -- each extra formal points to the next one, with Empty indicating the
1242 -- end of the list of extra formals). Another case of Extra_Formal arises
1243 -- in connection with unnesting of subprograms, where the ARECnF formal
1244 -- that represents an activation record pointer is an extra formal.
1246 -- Extra_Formals (Node28)
1247 -- Applies to subprograms and subprogram types, and also to entries
1248 -- and entry families. Returns first extra formal of the subprogram
1249 -- or entry. Returns Empty if there are no extra formals.
1251 -- Finalization_Master (Node23) [root type only]
1252 -- Defined in access-to-controlled or access-to-class-wide types. The
1253 -- field contains the entity of the finalization master which handles
1254 -- dynamically allocated controlled objects referenced by the access
1255 -- type. Empty for access-to-subprogram types. Empty for access types
1256 -- whose designated type does not need finalization actions.
1258 -- Finalize_Storage_Only (Flag158) [base type only]
1259 -- Defined in all types. Set on direct controlled types to which a
1260 -- valid Finalize_Storage_Only pragma applies. This flag is also set on
1261 -- composite types when they have at least one controlled component and
1262 -- all their controlled components are Finalize_Storage_Only. It is also
1263 -- inherited by type derivation except for direct controlled types where
1264 -- the Finalize_Storage_Only pragma is required at each level of
1267 -- Finalizer (Node28)
1268 -- Applies to package declarations and bodies. Contains the entity of the
1269 -- library-level program which finalizes all package-level controlled
1272 -- First_Component (synthesized)
1273 -- Applies to record types. Returns the first component by following the
1274 -- chain of declared entities for the record until a component is found
1275 -- (one with an Ekind of E_Component). The discriminants are skipped. If
1276 -- the record is null, then Empty is returned.
1278 -- First_Component_Or_Discriminant (synthesized)
1279 -- Similar to First_Component, but discriminants are not skipped, so will
1280 -- find the first discriminant if discriminants are present.
1282 -- First_Entity (Node17)
1283 -- Defined in all entities which act as scopes to which a list of
1284 -- associated entities is attached (blocks, class subtypes and types,
1285 -- entries, functions, loops, packages, procedures, protected objects,
1286 -- record types and subtypes, private types, task types and subtypes).
1287 -- Points to a list of associated entities using the Next_Entity field
1288 -- as a chain pointer with Empty marking the end of the list.
1290 -- First_Exit_Statement (Node8)
1291 -- Defined in E_Loop entity. The exit statements for a loop are chained
1292 -- (in reverse order of appearance) using this field to point to the
1293 -- first entry in the chain (last exit statement in the loop). The
1294 -- entries are chained through the Next_Exit_Statement field of the
1295 -- N_Exit_Statement node with Empty marking the end of the list.
1297 -- First_Formal (synthesized)
1298 -- Applies to subprograms and subprogram types, and also to entries
1299 -- and entry families. Returns first formal of the subprogram or entry.
1300 -- The formals are the first entities declared in a subprogram or in
1301 -- a subprogram type (the designated type of an Access_To_Subprogram
1302 -- definition) or in an entry.
1304 -- First_Formal_With_Extras (synthesized)
1305 -- Applies to subprograms and subprogram types, and also in entries
1306 -- and entry families. Returns first formal of the subprogram or entry.
1307 -- Returns Empty if there are no formals. The list returned includes
1308 -- all the extra formals (see description of Extra_Formals field).
1310 -- First_Index (Node17)
1311 -- Defined in array types and subtypes. By introducing implicit subtypes
1312 -- for the index constraints, we have the same structure for constrained
1313 -- and unconstrained arrays, subtype marks and discrete ranges are
1314 -- both represented by a subtype. This function returns the tree node
1315 -- corresponding to an occurrence of the first index (NOT the entity for
1316 -- the type). Subsequent indices are obtained using Next_Index. Note that
1317 -- this field is defined for the case of string literal subtypes, but is
1320 -- First_Literal (Node17)
1321 -- Defined in all enumeration types, including character and boolean
1322 -- types. This field points to the first enumeration literal entity
1323 -- for the type (i.e. it is set to First (Literals (N)) where N is
1324 -- the enumeration type definition node. A special case occurs with
1325 -- standard character and wide character types, where this field is
1326 -- Empty, since there are no enumeration literal lists in these cases.
1327 -- Note that this field is set in enumeration subtypes, but it still
1328 -- points to the first literal of the base type in this case.
1330 -- First_Private_Entity (Node16)
1331 -- Defined in all entities containing private parts (packages, protected
1332 -- types and subtypes, task types and subtypes). The entities on the
1333 -- entity chain are in order of declaration, so the entries for private
1334 -- entities are at the end of the chain. This field points to the first
1335 -- entity for the private part. It is Empty if there are no entities
1336 -- declared in the private part or if there is no private part.
1338 -- First_Rep_Item (Node6)
1339 -- Defined in all entities. If non-empty, points to a linked list of
1340 -- representation pragmas nodes and representation clause nodes that
1341 -- apply to the entity, linked using Next_Rep_Item, with Empty marking
1342 -- the end of the list. In the case of derived types and subtypes, the
1343 -- new entity inherits the chain at the point of declaration. This means
1344 -- that it is possible to have multiple instances of the same kind of rep
1345 -- item on the chain, in which case it is the first one that applies to
1348 -- Note: pragmas that can apply to more than one overloadable entity,
1349 -- (Convention, Interface, Inline, Inline_Always, Import, Export,
1350 -- External) are never present on this chain when they apply to
1351 -- overloadable entities, since it is impossible for a given pragma
1352 -- to be on more than one chain at a time.
1354 -- For most representation items, the representation information is
1355 -- reflected in other fields and flags in the entity. For example if a
1356 -- record representation clause is present, the component entities
1357 -- reflect the specified information. However, there are some items that
1358 -- are only reflected in the chain. These include:
1360 -- Machine_Attribute pragma
1361 -- Link_Alias pragma
1362 -- Linker_Constructor pragma
1363 -- Linker_Destructor pragma
1364 -- Weak_External pragma
1365 -- Thread_Local_Storage pragma
1367 -- If any of these items are present, then the flag Has_Gigi_Rep_Item is
1368 -- set, indicating that the backend should search the chain.
1370 -- Other representation items are included in the chain so that error
1371 -- messages can easily locate the relevant nodes for posting errors.
1372 -- Note in particular that size clauses are defined only for this
1373 -- purpose, and should only be accessed if Has_Size_Clause is set.
1375 -- Float_Rep (Uint10)
1376 -- Defined in floating-point entities. Contains a value of type
1377 -- Float_Rep_Kind. Together with the Digits_Value uniquely defines
1378 -- the floating-point representation to be used.
1380 -- Freeze_Node (Node7)
1381 -- Defined in all entities. If there is an associated freeze node for the
1382 -- entity, this field references this freeze node. If no freeze node is
1383 -- associated with the entity, then this field is Empty. See package
1384 -- Freeze for further details.
1386 -- From_Limited_With (Flag159)
1387 -- Defined in abtract states, package and type entities. Set to True when
1388 -- the related entity is generated by the expansion of a limited with
1389 -- clause. Such an entity is said to be a "shadow" - it acts as the
1390 -- abstract view of a state or variable or as the incomplete view of a
1391 -- type by inheriting relevant attributes from the said entity.
1393 -- Full_View (Node11)
1394 -- Defined in all type and subtype entities and in deferred constants.
1395 -- References the entity for the corresponding full type or constant
1396 -- declaration. For all types other than private and incomplete types,
1397 -- this field always contains Empty. If an incomplete type E1 is
1398 -- completed by a private type E2 whose full type declaration entity is
1399 -- E3 then the full view of E1 is E2, and the full view of E2 is E3. See
1400 -- also Underlying_Type.
1402 -- Generic_Homonym (Node11)
1403 -- Defined in generic packages. The generic homonym is the entity of
1404 -- a renaming declaration inserted in every generic unit. It is used
1405 -- to resolve the name of a local entity that is given by a qualified
1406 -- name, when the generic entity itself is hidden by a local name.
1408 -- Generic_Renamings (Elist23)
1409 -- Defined in package and subprogram instances. Holds mapping that
1410 -- associates generic parameters with the corresponding instances, in
1411 -- those cases where the instance is an entity.
1413 -- Handler_Records (List10)
1414 -- Defined in subprogram and package entities. Points to a list of
1415 -- identifiers referencing the handler record entities for the
1416 -- corresponding unit.
1418 -- Has_Aliased_Components (Flag135) [implementation base type only]
1419 -- Defined in array type entities. Indicates that the component type
1420 -- of the array is aliased. Should this also be set for records to
1421 -- indicate that at least one component is aliased (see processing in
1422 -- Sem_Prag.Process_Atomic_Independent_Shared_Volatile???)
1424 -- Has_Alignment_Clause (Flag46)
1425 -- Defined in all type entities and objects. Indicates if an alignment
1426 -- clause has been given for the entity. If set, then Alignment_Clause
1427 -- returns the N_Attribute_Definition node for the alignment attribute
1428 -- definition clause. Note that it is possible for this flag to be False
1429 -- even when Alignment_Clause returns non_Empty (this happens in the case
1430 -- of derived type declarations).
1432 -- Has_All_Calls_Remote (Flag79)
1433 -- Defined in all library unit entities. Set if the library unit has an
1434 -- All_Calls_Remote pragma. Note that such entities must also be RCI
1435 -- entities, so the flag Is_Remote_Call_Interface will always be set if
1436 -- this flag is set.
1438 -- Has_Atomic_Components (Flag86) [implementation base type only]
1439 -- Defined in all types and objects. Set only for an array type or
1440 -- an array object if a valid pragma Atomic_Components applies to the
1441 -- type or object. Note that in the case of an object, this flag is
1442 -- only set on the object if there was an explicit pragma for the
1443 -- object. In other words, the proper test for whether an object has
1444 -- atomic components is to see if either the object or its base type
1445 -- has this flag set. Note that in the case of a type, the pragma will
1446 -- be chained to the rep item chain of the first subtype in the usual
1449 -- Has_Attach_Handler (synthesized)
1450 -- Applies to record types that are constructed by the expander to
1451 -- represent protected types. Returns True if there is at least one
1452 -- Attach_Handler pragma in the corresponding specification.
1454 -- Has_Biased_Representation (Flag139)
1455 -- Defined in discrete types (where it applies to the type'size value),
1456 -- and to objects (both stand-alone and components), where it applies to
1457 -- the size of the object from a size or record component clause. In
1458 -- all cases it indicates that the size in question is smaller than
1459 -- would normally be required, but that the size requirement can be
1460 -- satisfied by using a biased representation, in which stored values
1461 -- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
1462 -- reduce the required size. For example, a type with a range of 1..2
1463 -- takes one bit, using 0 to represent 1 and 1 to represent 2.
1465 -- Note that in the object and component cases, the flag is only set if
1466 -- the type is unbiased, but the object specifies a smaller size than the
1467 -- size of the type, forcing biased representation for the object, but
1468 -- the subtype is still an unbiased type.
1470 -- Has_Completion (Flag26)
1471 -- Defined in all entities that require a completion (functions,
1472 -- procedures, private types, limited private types, incomplete types,
1473 -- constants and packages that require a body). The flag is set if the
1474 -- completion has been encountered and analyzed.
1476 -- Has_Completion_In_Body (Flag71)
1477 -- Defined in all entities for types and subtypes. Set only in "Taft
1478 -- amendment types" (incomplete types whose full declaration appears in
1479 -- the package body).
1481 -- Has_Complex_Representation (Flag140) [implementation base type only]
1482 -- Defined in all type entities. Set only for a record base type to
1483 -- which a valid pragma Complex_Representation applies.
1485 -- Has_Component_Size_Clause (Flag68) [implementation base type only]
1486 -- Defined in all type entities. Set if a component size clause is
1487 -- Defined for the given type. Note that this flag can be False even
1488 -- if Component_Size is non-zero (happens in the case of derived types).
1490 -- Has_Constrained_Partial_View (Flag187)
1491 -- Defined in private type and their completions, when the private
1492 -- type has no discriminants and the full view has discriminants with
1493 -- defaults. In Ada 2005 heap-allocated objects of such types are not
1494 -- constrained, and can change their discriminants with full assignment.
1496 -- Ada 2012 has an additional rule (3.3. (23/10.3)) concerning objects
1497 -- declared in a generic package body. Objects whose type is an untagged
1498 -- generic formal private type are considered to have a constrained
1499 -- partial view. The predicate Object_Type_Has_Constrained_Partial_View
1500 -- in sem_aux is used to test for this case.
1502 -- Has_Contiguous_Rep (Flag181)
1503 -- Defined in enumeration types. Set if the type as a representation
1504 -- clause whose entries are successive integers.
1506 -- Has_Controlling_Result (Flag98)
1507 -- Defined in E_Function entities. Set if the function is a primitive
1508 -- function of a tagged type which can dispatch on result.
1510 -- Has_Controlled_Component (Flag43) [base type only]
1511 -- Defined in all type and subtype entities. Set only for composite type
1512 -- entities which contain a component that either is a controlled type,
1513 -- or itself contains controlled component (i.e. either Is_Controlled or
1514 -- Has_Controlled_Component is set for at least one component).
1516 -- Has_Convention_Pragma (Flag119)
1517 -- Defined in all entities. Set for an entity for which a valid pragma
1518 -- Convention, Import, or Export has been given. Used to prevent more
1519 -- than one such pragma appearing for a given entity (RM B.1(45)).
1521 -- Has_Default_Aspect (Flag39) [base type only]
1522 -- Defined in entities for types and subtypes, set for scalar types with
1523 -- a Default_Value aspect and array types with a Default_Component_Value
1524 -- aspect. If this flag is set, then a corresponding aspect specification
1525 -- node will be present on the rep item chain for the entity. For a
1526 -- derived type that inherits a default from its ancestor, the default
1527 -- value is set, but it may be overridden by an aspect declaration on
1528 -- type type derivation.
1530 -- Has_Default_Init_Cond (Flag3) [base type only]
1531 -- Defined in all type entities. Set if pragma Default_Initial_Condition
1532 -- applies to a private type and by extension to its full view. This flag
1533 -- is mutually exclusive with flag Has_Inherited_Default_Init_Cond.
1535 -- Has_Delayed_Aspects (Flag200)
1536 -- Defined in all entities. Set if the Rep_Item chain for the entity has
1537 -- one or more N_Aspect_Definition nodes chained which are not to be
1538 -- evaluated till the freeze point. The aspect definition expression
1539 -- clause has been preanalyzed to get visibility at the point of use,
1540 -- but no other action has been taken.
1542 -- Has_Delayed_Freeze (Flag18)
1543 -- Defined in all entities. Set to indicate that an explicit freeze
1544 -- node must be generated for the entity at its freezing point. See
1545 -- separate section ("Delayed Freezing and Elaboration") for details.
1547 -- Has_Delayed_Rep_Aspects (Flag261)
1548 -- Defined in all types and subtypes. This flag is set if there is at
1549 -- least one aspect for a representation characteristic that has to be
1550 -- delayed and is one of the characteristics that may be inherited by
1551 -- types derived from this type if not overridden. If this flag is set,
1552 -- then types derived from this type have May_Inherit_Delayed_Rep_Aspects
1553 -- set, signalling that Freeze.Inhert_Delayed_Rep_Aspects must be called
1554 -- at the freeze point of the derived type.
1556 -- Has_Discriminants (Flag5)
1557 -- Defined in all types and subtypes. For types that are allowed to have
1558 -- discriminants (record types and subtypes, task types and subtypes,
1559 -- protected types and subtypes, private types, limited private types,
1560 -- and incomplete types), indicates if the corresponding type or subtype
1561 -- has a known discriminant part. Always false for all other types.
1563 -- Has_Dispatch_Table (Flag220)
1564 -- Defined in E_Record_Types that are tagged. Set to indicate that the
1565 -- corresponding dispatch table is already built. This flag is used to
1566 -- avoid duplicate construction of library level dispatch tables (because
1567 -- the declaration of library level objects cause premature construction
1568 -- of the table); otherwise the code that builds the table is added at
1569 -- the end of the list of declarations of the package.
1571 -- Has_Dynamic_Predicate_Aspect (Flag258)
1572 -- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect
1573 -- was explicitly applied to the type. Generally we treat predicates as
1574 -- static if possible, regardless of whether they are specified using
1575 -- Predicate, Static_Predicate, or Dynamic_Predicate. And if a predicate
1576 -- can be treated as static (i.e. its expression is predicate-static),
1577 -- then the flag Has_Static_Predicate will be set True. But there are
1578 -- cases where legality is affected by the presence of an explicit
1579 -- Dynamic_Predicate aspect. For example, even if a predicate looks
1580 -- static, you can't use it in a case statement if there is an explicit
1581 -- Dynamic_Predicate aspect specified. So test Has_Static_Predicate if
1582 -- you just want to know if the predicate can be evaluated statically,
1583 -- but test Has_Dynamic_Predicate_Aspect to enforce legality rules about
1584 -- the use of dynamic predicates.
1586 -- Has_Entries (synthesized)
1587 -- Applies to concurrent types. True if any entries are declared
1588 -- within the task or protected definition for the type.
1590 -- Has_Enumeration_Rep_Clause (Flag66)
1591 -- Defined in enumeration types. Set if an enumeration representation
1592 -- clause has been given for this enumeration type. Used to prevent more
1593 -- than one enumeration representation clause for a given type. Note
1594 -- that this does not imply a representation with holes, since the rep
1595 -- clause may merely confirm the default 0..N representation.
1597 -- Has_Exit (Flag47)
1598 -- Defined in loop entities. Set if the loop contains an exit statement.
1600 -- Has_Expanded_Contract (Flag240)
1601 -- Defined in functions, procedures, entries, and entry families. Set
1602 -- when a subprogram has a N_Contract node that has been expanded. The
1603 -- flag prevents double expansion of a contract when a construct is
1604 -- rewritten into something else and subsequently reanalyzed/expanded.
1606 -- Has_Foreign_Convention (synthesized)
1607 -- Applies to all entities. Determines if the Convention for the
1608 -- entity is a foreign convention (i.e. is other than Convention_Ada,
1609 -- Convention_Intrinsic, Convention_Entry or Convention_Protected).
1611 -- Has_Forward_Instantiation (Flag175)
1612 -- Defined in package entities. Set for packages that instantiate local
1613 -- generic entities before the corresponding generic body has been seen.
1614 -- If a package has a forward instantiation, we cannot inline subprograms
1615 -- appearing in the same package because the placement requirements of
1616 -- the instance will conflict with the linear elaboration of front-end
1619 -- Has_Fully_Qualified_Name (Flag173)
1620 -- Defined in all entities. Set if the name in the Chars field has been
1621 -- replaced by the fully qualified name, as used for debug output. See
1622 -- Exp_Dbug for a full description of the use of this flag and also the
1623 -- related flag Has_Qualified_Name.
1625 -- Has_Gigi_Rep_Item (Flag82)
1626 -- Defined in all entities. Set if the rep item chain (referenced by
1627 -- First_Rep_Item and linked through the Next_Rep_Item chain) contains a
1628 -- representation item that needs to be specially processed by the back
1629 -- end, i.e. one of the following items:
1631 -- Machine_Attribute pragma
1632 -- Linker_Alias pragma
1633 -- Linker_Constructor pragma
1634 -- Linker_Destructor pragma
1635 -- Weak_External pragma
1636 -- Thread_Local_Storage pragma
1638 -- If this flag is set, then the backend should scan the rep item chain
1639 -- to process any of these items that appear. At least one such item will
1642 -- Has_Homonym (Flag56)
1643 -- Defined in all entities. Set if an entity has a homonym in the same
1644 -- scope. Used by the backend to generate unique names for all entities.
1646 -- Has_Implicit_Dereference (Flag251)
1647 -- Defined in types and discriminants. Set if the type has an aspect
1648 -- Implicit_Dereference. Set also on the discriminant named in the aspect
1649 -- clause, to simplify type resolution.
1651 -- Has_Independent_Components (Flag34) [implementation base type only]
1652 -- Defined in all types and objects. Set only for a record type or an
1653 -- array type or array object if a valid pragma Independent_Components
1654 -- applies to the type or object. Note that in the case of an object,
1655 -- this flag is only set on the object if there was an explicit pragma
1656 -- for the object. In other words, the proper test for whether an object
1657 -- has independent components is to see if either the object or its base
1658 -- type has this flag set. Note that in the case of a type, the pragma
1659 -- will be chained to the rep item chain of the first subtype in the
1662 -- Has_Inheritable_Invariants (Flag248)
1663 -- Defined in all type entities. Set in private types from which one
1664 -- or more Invariant'Class aspects will be inherited if a another type is
1665 -- derived from the type (i.e. those types which have an Invariant'Class
1666 -- aspect, or which inherit one or more Invariant'Class aspects). Also
1667 -- set in the corresponding full types. Note that it might be the full
1668 -- type which has inheritable invariants, and in this case the flag will
1669 -- also be set in the private type.
1671 -- Has_Inherited_Default_Init_Cond (Flag133) [base type only]
1672 -- Defined in all type entities. Set when a derived type inherits pragma
1673 -- Default_Initial_Condition from its parent type. This flag is mutually
1674 -- exclusive with flag Has_Default_Init_Cond.
1676 -- Has_Initial_Value (Flag219)
1677 -- Defined in entities for variables and out parameters. Set if there
1678 -- is an explicit initial value expression in the declaration of the
1679 -- variable. Note that this is set only if this initial value is
1680 -- explicit, it is not set for the case of implicit initialization
1681 -- of access types or controlled types. Always set to False for out
1682 -- parameters. Also defined in entities for in and in-out parameters,
1683 -- but always false in these cases.
1685 -- Has_Interrupt_Handler (synthesized)
1686 -- Applies to all protected type entities. Set if the protected type
1687 -- definition contains at least one procedure to which a pragma
1688 -- Interrupt_Handler applies.
1690 -- Has_Invariants (Flag232)
1691 -- Defined in all type entities and in subprogram entities. Set in
1692 -- private types if an Invariant or Invariant'Class aspect applies to the
1693 -- type, or if the type inherits one or more Invariant'Class aspects.
1694 -- Also set in the corresponding full type. Note: if this flag is set
1695 -- True, then usually the Invariant_Procedure attribute is set once the
1696 -- type is frozen, however this may not be true in some error situations.
1697 -- Note that it might be the full type which has inheritable invariants,
1698 -- and then the flag will also be set in the private type.
1700 -- Has_Loop_Entry_Attributes (Flag260)
1701 -- Defined in E_Loop entities. Set when the loop is subject to at least
1702 -- one attribute 'Loop_Entry. The flag also implies that the loop has
1703 -- already been transformed. See Expand_Loop_Entry_Attribute for details.
1705 -- Has_Machine_Radix_Clause (Flag83)
1706 -- Defined in decimal types and subtypes, set if a Machine_Radix
1707 -- representation clause is present. This flag is used to detect
1708 -- the error of multiple machine radix clauses for a single type.
1710 -- Has_Master_Entity (Flag21)
1711 -- Defined in entities that can appear in the scope stack (see spec
1712 -- of Sem). It is set if a task master entity (_master) has been
1713 -- declared and initialized in the corresponding scope.
1715 -- Has_Missing_Return (Flag142)
1716 -- Defined in functions and generic functions. Set if there is one or
1717 -- more missing return statements in the function. This is used to
1718 -- control wrapping of the body in Exp_Ch6 to ensure that the program
1719 -- error exception is correctly raised in this case at runtime.
1721 -- Has_Nested_Block_With_Handler (Flag101)
1722 -- Defined in scope entities. Set if there is a nested block within the
1723 -- scope that has an exception handler and the two scopes are in the
1724 -- same procedure. This is used by the backend for controlling certain
1725 -- optimizations to ensure that they are consistent with exceptions.
1726 -- See documentation in backend for further details.
1728 -- Has_Nested_Subprogram (Flag282)
1729 -- Defined in subprogram entities. Set for a subprogram which contains at
1730 -- least one nested subprogram.
1732 -- Has_Non_Limited_View (synth)
1733 -- Defined in E_Incomplete_Type, E_Incomplete_Subtype, E_Class_Wide_Type,
1734 -- E_Abstract_State entities. True if their Non_Limited_View attribute
1737 -- Has_Non_Null_Refinement (synth)
1738 -- Defined in E_Abstract_State entities. True if the state has at least
1739 -- one variable or state constituent in aspect/pragma Refined_State.
1741 -- Has_Non_Standard_Rep (Flag75) [implementation base type only]
1742 -- Defined in all type entities. Set when some representation clause
1743 -- or pragma causes the representation of the item to be significantly
1744 -- modified. In this category are changes of small or radix for a
1745 -- fixed-point type, change of component size for an array, and record
1746 -- or enumeration representation clauses, as well as packed pragmas.
1747 -- All other representation clauses (e.g. Size and Alignment clauses)
1748 -- are not considered to be significant since they do not affect
1749 -- stored bit patterns.
1751 -- Has_Null_Abstract_State (synth)
1752 -- Defined in package entities. True if the package is subject to a null
1753 -- Abstract_State aspect/pragma.
1755 -- Has_Null_Refinement (synth)
1756 -- Defined in E_Abstract_State entities. True if the state has a null
1757 -- refinement in aspect/pragma Refined_State.
1759 -- Has_Object_Size_Clause (Flag172)
1760 -- Defined in entities for types and subtypes. Set if an Object_Size
1761 -- clause has been processed for the type Used to prevent multiple
1762 -- Object_Size clauses for a given entity.
1764 -- Has_Out_Or_In_Out_Parameter (Flag110)
1765 -- Present in subprograms, generic subprograms, entries, and entry
1766 -- families. Set if they have at least one OUT or IN OUT parameter
1767 -- (allowed for functions only in Ada 2012).
1769 -- Has_Per_Object_Constraint (Flag154)
1770 -- Defined in E_Component entities. Set if the subtype of the component
1771 -- has a per object constraint. Per object constraints result from the
1772 -- following situations :
1774 -- 1. N_Attribute_Reference - when the prefix is the enclosing type and
1775 -- the attribute is Access.
1776 -- 2. N_Discriminant_Association - when the expression uses the
1777 -- discriminant of the enclosing type.
1778 -- 3. N_Index_Or_Discriminant_Constraint - when at least one of the
1779 -- individual constraints is a per object constraint.
1780 -- 4. N_Range - when the lower or upper bound uses the discriminant of
1781 -- the enclosing type.
1782 -- 5. N_Range_Constraint - when the range expression uses the
1783 -- discriminant of the enclosing type.
1785 -- Has_Pragma_Controlled (Flag27) [implementation base type only]
1786 -- Defined in access type entities. It is set if a pragma Controlled
1787 -- applies to the access type.
1789 -- Has_Pragma_Elaborate_Body (Flag150)
1790 -- Defined in all entities. Set in compilation unit entities if a
1791 -- pragma Elaborate_Body applies to the compilation unit.
1793 -- Has_Pragma_Inline (Flag157)
1794 -- Defined in all entities. Set for functions and procedures for which a
1795 -- pragma Inline or Inline_Always applies to the subprogram. Note that
1796 -- this flag can be set even if Is_Inlined is not set. This happens for
1797 -- pragma Inline (if Inline_Active is False). In other words, the flag
1798 -- Has_Pragma_Inline represents the formal semantic status, and is used
1799 -- for checking semantic correctness. The flag Is_Inlined indicates
1800 -- whether inlining is actually active for the entity.
1802 -- Has_Pragma_Inline_Always (Flag230)
1803 -- Defined in all entities. Set for functions and procedures for which a
1804 -- pragma Inline_Always applies. Note that if this flag is set, the flag
1805 -- Has_Pragma_Inline is also set.
1807 -- Has_Pragma_No_Inline (Flag201)
1808 -- Defined in all entities. Set for functions and procedures for which a
1809 -- pragma No_Inline applies. Note that if this flag is set, the flag
1810 -- Has_Pragma_Inline_Always cannot be set.
1812 -- Has_Pragma_Ordered (Flag198) [implementation base type only]
1813 -- Defined in entities for enumeration types. If set indicates that a
1814 -- valid pragma Ordered was given for the type. This flag is inherited
1815 -- by derived enumeration types. We don't need to distinguish the derived
1816 -- case since we allow multiple occurrences of this pragma anyway.
1818 -- Has_Pragma_Pack (Flag121) [implementation base type only]
1819 -- Defined in array and record type entities. If set, indicates that a
1820 -- valid pragma Pack was given for the type. Note that this flag is not
1821 -- inherited by derived type. See also the Is_Packed flag.
1823 -- Has_Pragma_Pure (Flag203)
1824 -- Defined in all entities. If set, indicates that a valid pragma Pure
1825 -- was given for the entity. In some cases, we need to test whether
1826 -- Is_Pure was explicitly set using this pragma.
1828 -- Has_Pragma_Preelab_Init (Flag221)
1829 -- Defined in type and subtype entities. If set indicates that a valid
1830 -- pragma Preelaborable_Initialization applies to the type.
1832 -- Has_Pragma_Pure_Function (Flag179)
1833 -- Defined in all entities. If set, indicates that a valid pragma
1834 -- Pure_Function was given for the entity. In some cases, we need to
1835 -- know that Is_Pure was explicitly set using this pragma. We also set
1836 -- this flag for some internal entities that we know should be treated
1837 -- as pure for optimization purposes.
1839 -- Has_Pragma_Thread_Local_Storage (Flag169)
1840 -- Defined in all entities. If set, indicates that a valid pragma
1841 -- Thread_Local_Storage was given for the entity.
1843 -- Has_Pragma_Unmodified (Flag233)
1844 -- Defined in all entities. Can only be set for variables (E_Variable,
1845 -- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified
1846 -- applies to the variable, indicating that no warning should be given
1847 -- if the entity is never modified. Note that clients should generally
1848 -- not test this flag directly, but instead use function Has_Unmodified.
1850 -- Has_Pragma_Unreferenced (Flag180)
1851 -- Defined in all entities. Set if a valid pragma Unreferenced applies
1852 -- to the entity, indicating that no warning should be given if the
1853 -- entity has no references, but a warning should be given if it is
1854 -- in fact referenced. For private types, this flag is set in both the
1855 -- private entity and full entity if the pragma applies to either. Note
1856 -- that clients should generally not test this flag directly, but instead
1857 -- use function Has_Unreferenced.
1859 -- Has_Pragma_Unreferenced_Objects (Flag212)
1860 -- Defined in type and subtype entities. Set if a valid pragma
1861 -- Unreferenced_Objects applies to the type, indicating that no warning
1862 -- should be given for objects of such a type for being unreferenced
1863 -- (but unlike the case with pragma Unreferenced, it is ok to reference
1864 -- such an object and no warning is generated.
1866 -- Has_Predicates (Flag250)
1867 -- Defined in type and subtype entities. Set if a pragma Predicate or
1868 -- Predicate aspect applies to the type or subtype, or if it inherits a
1869 -- Predicate aspect from its parent or progenitor types.
1871 -- Has_Primitive_Operations (Flag120) [base type only]
1872 -- Defined in all type entities. Set if at least one primitive operation
1873 -- is defined for the type.
1875 -- Has_Private_Ancestor (Flag151)
1876 -- Applies to type extensions. True if some ancestor is derived from a
1877 -- private type, making some components invisible and aggregates illegal.
1878 -- This flag is set at the point of derivation. The legality of the
1879 -- aggregate must be rechecked because it also depends on the visibility
1880 -- at the point the aggregate is resolved. See sem_aggr.adb. This is part
1883 -- Has_Private_Declaration (Flag155)
1884 -- Defined in all entities. Set if it is the defining entity of a private
1885 -- type declaration or its corresponding full declaration. This flag is
1886 -- thus preserved when the full and the partial views are exchanged, to
1887 -- indicate if a full type declaration is a completion. Used for semantic
1888 -- checks in E.4(18) and elsewhere.
1890 -- Has_Protected (Flag271) [base type only]
1891 -- Defined in all type entities. Set on protected types themselves, and
1892 -- also (recursively) on any composite type which has a component for
1893 -- which Has_Protected is set. The meaning is that an allocator for
1894 -- or declaration of such an object must create the required protected
1895 -- objects. Note: the flag is not set on access types, even if they
1896 -- designate an object that Has_Protected.
1898 -- Has_Qualified_Name (Flag161)
1899 -- Defined in all entities. Set if the name in the Chars field has
1900 -- been replaced by its qualified name, as used for debug output. See
1901 -- Exp_Dbug for a full description of qualification requirements. For
1902 -- some entities, the name is the fully qualified name, but there are
1903 -- exceptions. In particular, for local variables in procedures, we
1904 -- do not include the procedure itself or higher scopes. See also the
1905 -- flag Has_Fully_Qualified_Name, which is set if the name does indeed
1906 -- include the fully qualified name.
1908 -- Has_RACW (Flag214)
1909 -- Defined in package spec entities. Set if the spec contains the
1910 -- declaration of a remote access-to-classwide type.
1912 -- Has_Record_Rep_Clause (Flag65) [implementation base type only]
1913 -- Defined in record types. Set if a record representation clause has
1914 -- been given for this record type. Used to prevent more than one such
1915 -- clause for a given record type. Note that this is initially cleared
1916 -- for a derived type, even though the representation is inherited. See
1917 -- also the flag Has_Specified_Layout.
1919 -- Has_Recursive_Call (Flag143)
1920 -- Defined in procedures. Set if a direct parameterless recursive call
1921 -- is detected while analyzing the body. Used to activate some error
1922 -- checks for infinite recursion.
1924 -- Has_Shift_Operator (Flag267) [base type only]
1925 -- Defined in integer types. Set in the base type of an integer type for
1926 -- which at least one of the shift operators is defined.
1928 -- Has_Size_Clause (Flag29)
1929 -- Defined in entities for types and objects. Set if a size clause is
1930 -- defined for the entity. Used to prevent multiple Size clauses for a
1931 -- given entity. Note that it is always initially cleared for a derived
1932 -- type, even though the Size for such a type is inherited from a Size
1933 -- clause given for the parent type.
1935 -- Has_Small_Clause (Flag67)
1936 -- Defined in ordinary fixed point types (but not subtypes). Indicates
1937 -- that a small clause has been given for the entity. Used to prevent
1938 -- multiple Small clauses for a given entity. Note that it is always
1939 -- initially cleared for a derived type, even though the Small for such
1940 -- a type is inherited from a Small clause given for the parent type.
1942 -- Has_Specified_Layout (Flag100) [implementation base type only]
1943 -- Defined in all type entities. Set for a record type or subtype if
1944 -- the record layout has been specified by a record representation
1945 -- clause. Note that this differs from the flag Has_Record_Rep_Clause
1946 -- in that it is inherited by a derived type. Has_Record_Rep_Clause is
1947 -- used to indicate that the type is mentioned explicitly in a record
1948 -- representation clause, and thus is not inherited by a derived type.
1949 -- This flag is always False for non-record types.
1951 -- Has_Specified_Stream_Input (Flag190)
1952 -- Has_Specified_Stream_Output (Flag191)
1953 -- Has_Specified_Stream_Read (Flag192)
1954 -- Has_Specified_Stream_Write (Flag193)
1955 -- Defined in all type and subtype entities. Set for a given view if the
1956 -- corresponding stream-oriented attribute has been defined by an
1957 -- attribute definition clause. When such a clause occurs, a TSS is set
1958 -- on the underlying full view; the flags are used to track visibility of
1959 -- the attribute definition clause for partial or incomplete views.
1961 -- Has_Static_Discriminants (Flag211)
1962 -- Defined in record subtypes constrained by discriminant values. Set if
1963 -- all the discriminant values have static values, meaning that in the
1964 -- case of a variant record, the component list can be trimmed down to
1965 -- include only the components corresponding to these discriminants.
1967 -- Has_Static_Predicate (Flag269)
1968 -- Defined in all types and subtypes. Set if the type (which must be a
1969 -- scalar type) has a predicate whose expression is predicate-static.
1970 -- This can result from the use of any Predicate, Static_Predicate, or
1971 -- Dynamic_Predicate aspect. We can distinguish these cases by testing
1972 -- Has_Static_Predicate_Aspect and Has_Dynamic_Predicate_Aspect. See
1973 -- description of the latter flag for further information on dynamic
1974 -- predicates which are also static.
1976 -- Has_Static_Predicate_Aspect (Flag259)
1977 -- Defined in all types and subtypes. Set if a Static_Predicate aspect
1978 -- applies to the type. Note that we can tell if a static predicate is
1979 -- present by looking at Has_Static_Predicate, but this could have come
1980 -- from a Predicate aspect or pragma or even from a Dynamic_Predicate
1981 -- aspect. When we need to know the difference (e.g. to know what set of
1982 -- check policies apply, use this flag and Has_Dynamic_Predicate_Aspect
1983 -- to determine which case we have).
1985 -- Has_Storage_Size_Clause (Flag23) [implementation base type only]
1986 -- Defined in task types and access types. It is set if a Storage_Size
1987 -- clause is present for the type. Used to prevent multiple clauses for
1988 -- one type. Note that this flag is initially cleared for a derived type
1989 -- even though the Storage_Size for such a type is inherited from a
1990 -- Storage_Size clause given for the parent type. Note that in the case
1991 -- of access types, this flag is defined only in the root type, since a
1992 -- storage size clause cannot be given to a derived type.
1994 -- Has_Stream_Size_Clause (Flag184)
1995 -- Defined in all entities. It is set for types which have a Stream_Size
1996 -- clause attribute. Used to prevent multiple Stream_Size clauses for a
1997 -- given entity, and also whether it is necessary to check for a stream
2000 -- Has_Task (Flag30) [base type only]
2001 -- Defined in all type entities. Set on task types themselves, and also
2002 -- (recursively) on any composite type which has a component for which
2003 -- Has_Task is set. The meaning is that an allocator or declaration of
2004 -- such an object must create the required tasks. Note: the flag is not
2005 -- set on access types, even if they designate an object that Has_Task.
2007 -- Has_Thunks (Flag228)
2008 -- Applies to E_Constant entities marked Is_Tag. True for secondary tag
2009 -- referencing a dispatch table whose contents are pointers to thunks.
2011 -- Has_Unchecked_Union (Flag123) [base type only]
2012 -- Defined in all type entities. Set on unchecked unions themselves
2013 -- and (recursively) on any composite type which has a component for
2014 -- which Has_Unchecked_Union is set. The meaning is that a comparison
2015 -- operation or 'Valid_Scalars reference for the type is not permitted.
2016 -- Note that the flag is not set on access types, even if they designate
2017 -- an object that has the flag Has_Unchecked_Union set.
2019 -- Has_Unknown_Discriminants (Flag72)
2020 -- Defined in all entities. Set for types with unknown discriminants.
2021 -- Types can have unknown discriminants either from their declaration or
2022 -- through type derivation. The use of this flag exactly meets the spec
2023 -- in RM 3.7(26). Note that all class-wide types are considered to have
2024 -- unknown discriminants. Note that both flags Has_Discriminants and
2025 -- Has_Unknown_Discriminants may be true for a type. Class-wide types and
2026 -- their subtypes have unknown discriminants and can have declared ones
2027 -- as well. Private types declared with unknown discriminants may have a
2028 -- full view that has explicit discriminants, and both flag will be set
2029 -- on the partial view, to insure that discriminants are properly
2030 -- inherited in certain contexts.
2032 -- Has_Uplevel_Reference (Flag215)
2033 -- Defined in all entities. Indicates that the entity is locally defined
2034 -- within a subprogram P, and there is a reference to the entity within
2035 -- a subprogram nested within P (at any depth). Set only for the VM case
2036 -- (where it is set for variables, constants, and loop parameters). Note
2037 -- that this is similar in usage to Is_Uplevel_Referenced_Entity (which
2038 -- is used when we are unnesting subprograms), but the usages are a bit
2039 -- different and it is cleaner to leave the old VM usage unchanged.
2041 -- Has_Visible_Refinement (Flag263)
2042 -- Defined in E_Abstract_State entities. Set when a state has at least
2043 -- one refinement constituent and analysis is in the region between
2044 -- pragma Refined_State and the end of the package body declarations.
2046 -- Has_Volatile_Components (Flag87) [implementation base type only]
2047 -- Defined in all types and objects. Set only for an array type or array
2048 -- object if a valid pragma Volatile_Components or a valid pragma
2049 -- Atomic_Components applies to the type or object. Note that in the case
2050 -- of an object, this flag is only set on the object if there was an
2051 -- explicit pragma for the object. In other words, the proper test for
2052 -- whether an object has volatile components is to see if either the
2053 -- object or its base type has this flag set. Note that in the case of a
2054 -- type the pragma will be chained to the rep item chain of the first
2055 -- subtype in the usual manner.
2057 -- Has_Xref_Entry (Flag182)
2058 -- Defined in all entities. Set if an entity has an entry in the Xref
2059 -- information generated in ali files. This is true for all source
2060 -- entities in the extended main source file. It is also true of entities
2061 -- in other packages that are referenced directly or indirectly from the
2062 -- main source file (indirect reference occurs when the main source file
2063 -- references an entity with a type reference. See package Lib.Xref for
2064 -- further details).
2066 -- Hiding_Loop_Variable (Node8)
2067 -- Defined in variables. Set only if a variable of a discrete type is
2068 -- hidden by a loop variable in the same local scope, in which case
2069 -- the Hiding_Loop_Variable field of the hidden variable points to
2070 -- the E_Loop_Parameter entity doing the hiding. Used in processing
2071 -- warning messages if the hidden variable turns out to be unused
2072 -- or is referenced without being set.
2075 -- Defined in all entities. Link for list of entities that have the
2076 -- same source name and that are declared in the same or enclosing
2077 -- scopes. Homonyms in the same scope are overloaded. Used for name
2078 -- resolution and for the generation of debugging information.
2080 -- Implementation_Base_Type (synthesized)
2081 -- Applies to all entities. For types, similar to Base_Type, but never
2082 -- returns a private type when applied to a non-private type. Instead in
2083 -- this case, it always returns the Underlying_Type of the base type, so
2084 -- that we still have a concrete type. For entities other than types,
2085 -- returns the entity unchanged.
2087 -- Import_Pragma (Node35)
2088 -- Defined in subprogram entities. Set if a valid pragma Import or pragma
2089 -- Import_Function or pragma Import_Procedure applies to the subprogram,
2090 -- in which case this field points to the pragma (we can't use the normal
2091 -- Rep_Item chain mechanism, because a single pragma Import can apply
2092 -- to multiple subprogram entities).
2094 -- Incomplete_Actuals (Elist24)
2095 -- Defined on package entities that are instances. Indicates the actuals
2096 -- types in the instantiation that are limited views. If this list is
2097 -- not empty, the instantiation, which appears in a package declaration,
2098 -- is relocated to the corresponding package body, which must have a
2099 -- corresponding nonlimited with_clause.
2101 -- In_Package_Body (Flag48)
2102 -- Defined in package entities. Set on the entity that denotes the
2103 -- package (the defining occurrence of the package declaration) while
2104 -- analyzing and expanding the package body. Reset on completion of
2105 -- analysis/expansion.
2107 -- In_Private_Part (Flag45)
2108 -- Defined in all entities. Can be set only in package entities and
2109 -- objects. For package entities, this flag is set to indicate that the
2110 -- private part of the package is being analyzed. The flag is reset at
2111 -- the end of the package declaration. For objects it indicates that the
2112 -- declaration of the object occurs in the private part of a package.
2114 -- Initialization_Statements (Node28)
2115 -- Defined in constants and variables. For a composite object initialized
2116 -- initialized with an aggregate that has been converted to a sequence
2117 -- of assignments, points to a block statement containing the
2120 -- Inner_Instances (Elist23)
2121 -- Defined in generic units. Contains element list of units that are
2122 -- instantiated within the given generic. Used to diagnose circular
2125 -- Interface_Alias (Node25)
2126 -- Defined in subprograms that cover a primitive operation of an abstract
2127 -- interface type. Can be set only if the Is_Hidden flag is also set,
2128 -- since such entities are always hidden. Points to its associated
2129 -- interface subprogram. It is used to register the subprogram in
2130 -- secondary dispatch table of the interface (Ada 2005: AI-251).
2132 -- Interface_Name (Node21)
2133 -- Defined in constants, variables, exceptions, functions, procedures,
2134 -- packages, components (JGNAT only), discriminants (JGNAT only), and
2135 -- access to subprograms (JGNAT only). Set to Empty unless an export,
2136 -- import, or interface name pragma has explicitly specified an external
2137 -- name, in which case it references an N_String_Literal node for the
2138 -- specified external name. Note that if this field is Empty, and
2139 -- Is_Imported or Is_Exported is set, then the default interface name
2140 -- is the name of the entity, cased in a manner that is appropriate to
2141 -- the system in use. Note that Interface_Name is ignored if an address
2142 -- clause is present (since it is meaningless in this case).
2144 -- An additional special case usage of this field is in JGNAT for
2145 -- E_Component and E_Discriminant. JGNAT allows these entities to be
2146 -- imported by specifying pragma Import within a component's containing
2147 -- record definition. This supports interfacing to object fields defined
2148 -- within Java classes, and such pragmas are generated by the jvm2ada
2149 -- binding generator tool whenever it processes classes with public
2150 -- object fields. A pragma Import for a component can define the
2151 -- External_Name of the imported Java field (which is generally needed,
2152 -- because Java names are case sensitive).
2154 -- Interfaces (Elist25)
2155 -- Defined in record types and subtypes. List of abstract interfaces
2156 -- implemented by a tagged type that are not already implemented by the
2157 -- ancestors (Ada 2005: AI-251).
2159 -- Invariant_Procedure (synthesized)
2160 -- Defined in types and subtypes. Set for private types if one or more
2161 -- Invariant, or Invariant'Class, or inherited Invariant'Class aspects
2162 -- apply to the type. Points to the entity for a procedure which checks
2163 -- the invariant. This invariant procedure takes a single argument of the
2164 -- given type, and returns if the invariant holds, or raises exception
2165 -- Assertion_Error with an appropriate message if it does not hold. This
2166 -- attribute is defined but always empty for private subtypes. This
2167 -- attribute is also set for the corresponding full type.
2169 -- Note: the reason this is marked as a synthesized attribute is that the
2170 -- way this is stored is as an element of the Subprograms_For_Type field.
2173 -- Defined in packages and types. Set when analyzing a use clause for
2174 -- the corresponding entity. Reset at end of corresponding declarative
2175 -- part. The flag on a type is also used to determine the visibility of
2176 -- the primitive operators of the type.
2178 -- Is_Abstract_Subprogram (Flag19)
2179 -- Defined in all subprograms and entries. Set for abstract subprograms.
2180 -- Always False for enumeration literals and entries. See also

2191 -- Applies to all types, true for named and anonymous access to
2192 -- protected subprograms.

2195 -- Applies to all entities, true for access types and subtypes
2197 -- Is_Ada_2005_Only (Flag185)
2198 -- Defined in all entities, true if a valid pragma Ada_05 or Ada_2005
2199 -- applies to the entity which specifically names the entity, indicating
2200 -- that the entity is Ada 2005 only. Note that this flag is not set if
2201 -- the entity is part of a unit compiled with the normal no-argument form
2202 -- of pragma Ada_05 or Ada_2005.
2204 -- Is_Ada_2012_Only (Flag199)
2205 -- Defined in all entities, true if a valid pragma Ada_12 or Ada_2012
2206 -- applies to the entity which specifically names the entity, indicating
2207 -- that the entity is Ada 2012 only. Note that this flag is not set if
2208 -- the entity is part of a unit compiled with the normal no-argument form
2209 -- of pragma Ada_12 or Ada_2012.
2211 -- Is_Aliased (Flag15)
2212 -- Defined in all entities. Set for objects and types whose declarations
2213 -- carry the keyword aliased, and on record components that have the
2214 -- keyword. For Ada 2012, also applies to formal parameters.
2216 -- Is_Atomic (Flag85)
2217 -- Defined in all type entities, and also in constants, components, and
2218 -- variables. Set if a pragma Atomic or Shared applies to the entity.
2219 -- In the case of private and incomplete types, this flag is set in
2220 -- both the partial view and the full view.
2222 -- Is_Atomic_Or_VFA (synth)
2223 -- Defined in all type entities, and also in constants, components and
2224 -- variables. Set if a pragma Atomic or Shared or Volatile_Full_Access
2225 -- applies to the entity. For many purposes VFA objects should be treated
2226 -- the same as Atomic objects, and this predicate is intended for that
2227 -- usage. In the case of private and incomplete types, the predicate
2228 -- applies to both the partial view and the full view.
2230 -- Is_Array_Type (synthesized)
2231 -- Applies to all entities, true for array types and subtypes
2233 -- Is_Asynchronous (Flag81)
2234 -- Defined in all type entities and in procedure entities. Set
2235 -- if a pragma Asynchronous applies to the entity.
2237 -- Is_Base_Type (synthesized)
2238 -- Applies to type and subtype entities. True if entity is a base type
2240 -- Is_Bit_Packed_Array (Flag122) [implementation base type only]
2241 -- Defined in all entities. This flag is set for a packed array type that
2242 -- is bit packed (i.e. the component size is known by the front end and
2243 -- is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed is always set
2244 -- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be
2245 -- set without Is_Bit_Packed_Array for the case of an array having one or
2246 -- more index types that are enumeration types with non-standard
2247 -- enumeration representations.
2249 -- Is_Boolean_Type (synthesized)
2250 -- Applies to all entities, true for boolean types and subtypes,
2251 -- i.e. Standard.Boolean and all types ultimately derived from it.
2253 -- Is_Called (Flag102)
2254 -- Defined in subprograms. Returns true if the subprogram is called
2255 -- in the unit being compiled or in a unit in the context. Used for
2258 -- Is_Character_Type (Flag63)
2259 -- Defined in all entities. Set for character types and subtypes,
2260 -- i.e. enumeration types that have at least one character literal.
2262 -- Is_Checked_Ghost_Entity (Flag277)
2263 -- Applies to all entities. Set for abstract states, [generic] packages,
2264 -- [generic] subprograms, components, discriminants, formal parameters,
2265 -- objects, package bodies, subprogram bodies, and [sub]types subject to
2266 -- pragma Ghost or inherit "ghostness" from an enclosing construct, and
2267 -- subject to Assertion_Policy Ghost => Check.
2269 -- Is_Child_Unit (Flag73)
2270 -- Defined in all entities. Set only for defining entities of program
2271 -- units that are child units (but False for subunits).

2279 -- some class-wide subtype entity references this record type.
2281 -- Is_Compilation_Unit (Flag149)
2282 -- Defined in all entities. Set if the entity is a package or subprogram
2283 -- entity for a compilation unit other than a subunit (since we treat
2284 -- subunits as part of the same compilation operation as the ultimate
2285 -- parent, we do not consider them to be separate units for this flag).
2287 -- Is_Completely_Hidden (Flag103)
2288 -- Defined in all entities. This flag can be set only for E_Discriminant
2289 -- entities. This flag can be set only for girder discriminants of
2290 -- untagged types. When set, the entity is a girder discriminant of a
2291 -- derived untagged type which is not directly visible in the derived
2292 -- type because the derived type or one of its ancestors have renamed the
2293 -- discriminants in the root type. Note: there are girder discriminants
2294 -- which are not Completely_Hidden (e.g. discriminants of a root type).
2296 -- Is_Composite_Type (synthesized)
2297 -- Applies to all entities, true for all composite types and

2304 -- concurrent type, such as record type is constructed, and task and
2305 -- protected objects are instances of this record type at runtime
2306 -- (The backend will replace declarations of the concurrent type using
2307 -- the declarations of the corresponding record type). See Exp_Ch9 for
2310 -- Is_Concurrent_Type (synthesized)
2311 -- Applies to all entities, true for task types and subtypes and for
2312 -- protected types and subtypes.

2333 -- the backend to determine whether a template must be constructed.
2335 -- Is_Constructor (Flag76)
2336 -- Defined in function and procedure entities. Set if a pragma
2337 -- CPP_Constructor applies to the subprogram.

2342 -- Ada.Finalization.Limited_Controlled.
2344 -- Is_Controlled_Active (synth) [base type only]
2345 -- Defined in all type entities. Set if Is_Controlled is set for the
2346 -- type, and Disable_Controlled is not set.
2348 -- Is_Controlling_Formal (Flag97)
2349 -- Defined in all Formal_Kind entities. Marks the controlling parameters
2350 -- of dispatching operations.
2352 -- Is_CPP_Class (Flag74)

2417 -- entities and False for all other entity kinds.
2419 -- Is_Entry_Formal (Flag52)
2420 -- Defined in all entities. Set only for entry formals (which can only

2422 -- test for the need to replace references in Exp_Ch2.
2424 -- Is_Exported (Flag99)
2425 -- Defined in all entities. Set if the entity is exported. For now we
2426 -- only allow the export of constants, exceptions, functions, procedures

2463 -- Defined in E_Private_Subtype and E_Record_Subtype entities. Means the

2466 -- have been found or frozen yet.
2468 -- Is_Frozen (Flag4)

2484 -- Defined in all type and subtype entities. Set in the subtype
2485 -- declaration that renames the generic formal as a subtype of the

2488 -- accidental overloading that occurs when different formal types get the
2491 -- Is_Generic_Instance (Flag130)
2492 -- Defined in all entities. Set to indicate that the entity is an

2497 -- Applies to all entities. Yields True for a generic subprogram
2498 -- (generic function, generic subprogram), False for all other entities.
2500 -- Is_Generic_Type (Flag13)
2501 -- Defined in all entities. Set for types which are generic formal types.
2502 -- Such types have an Ekind that corresponds to their classification, so
2503 -- the Ekind cannot be used to identify generic formal types.
2505 -- Is_Generic_Unit (synthesized)
2506 -- Applies to all entities. Yields True for a generic unit (generic
2507 -- package, generic function, generic procedure), and False for all
2510 -- Is_Hidden (Flag57)
2511 -- Defined in all entities. Set for all entities declared in the
2512 -- private part or body of a package. Also marks generic formals of a
2513 -- formal package declared without a box. For library level entities,
2514 -- this flag is set if the entity is not publicly visible. This flag
2515 -- is reset when compiling the body of the package where the entity
2516 -- is declared, when compiling the private part or body of a public
2517 -- child unit, and when compiling a private child unit (see Install_
2518 -- Private_Declaration in sem_ch7).
2520 -- Is_Hidden_Non_Overridden_Subpgm (Flag2)
2521 -- Defined in all entities. Set for implicitly declared subprograms
2522 -- that require overriding or are null procedures, and are hidden by
2523 -- a non-fully conformant homograph with the same characteristics
2524 -- (Ada RM 8.3 12.3/2).
2526 -- Is_Hidden_Open_Scope (Flag171)
2527 -- Defined in all entities. Set for a scope that contains the
2528 -- instantiation of a child unit, and whose entities are not visible
2529 -- during analysis of the instance.
2531 -- Is_Ignored_Ghost_Entity (Flag278)
2532 -- Applies to all entities. Set for abstract states, [generic] packages,
2533 -- [generic] subprograms, components, discriminants, formal parameters,
2534 -- objects, package bodies, subprogram bodies, and [sub]types subject to
2535 -- pragma Ghost or inherit "ghostness" from an enclosing construct, and
2536 -- subject to Assertion_Policy Ghost => Ignore.
2538 -- Is_Immediately_Visible (Flag7)
2539 -- Defined in all entities. Set if entity is immediately visible, i.e.
2540 -- is defined in some currently open scope (RM 8.3(4)).
2542 -- Is_Implementation_Defined (Flag254)
2543 -- Defined in all entities. Set if a pragma Implementation_Defined is
2544 -- applied to the pragma. Used to mark all implementation defined
2545 -- identifiers in standard library packages, and to implement the
2546 -- restriction No_Implementation_Identifiers.
2548 -- Is_Imported (Flag24)
2549 -- Defined in all entities. Set if the entity is imported. For now we
2550 -- only allow the import of exceptions, functions, procedures, packages.
2551 -- and variables. Exceptions, packages and types can only be imported in
2552 -- the Java VM implementation.
2554 -- Is_Incomplete_Or_Private_Type (synthesized)
2555 -- Applies to all entities, true for private and incomplete types
2557 -- Is_Incomplete_Type (synthesized)
2558 -- Applies to all entities, true for incomplete types and subtypes
2560 -- Is_Independent (Flag268)
2561 -- Defined in all type entities, and also in constants, components and
2562 -- variables. Set if a valid pragma or aspect Independent applies to the
2563 -- entity, or if a valid pragma or aspect Independent_Components applies
2564 -- to the enclosing record type for a component. Also set if a pragma
2565 -- Shared or pragma Atomic applies to the entity. In the case of private
2566 -- and incomplete types, this flag is set in both the partial view and
2569 -- Is_Inlined (Flag11)
2570 -- Defined in all entities. Set for functions and procedures which are
2571 -- to be inlined. For subprograms created during expansion, this flag
2572 -- may be set directly by the expander to request inlining. Also set
2573 -- for packages that contain inlined subprograms, whose bodies must be
2574 -- be compiled. Is_Inlined is also set on generic subprograms and is
2575 -- inherited by their instances. It is also set on the body entities
2576 -- of inlined subprograms. See also Has_Pragma_Inline.
2578 -- Is_Inlined_Always (Flag1)
2579 -- Defined in subprograms. Set for functions and procedures which are
2580 -- always inlined in GNATprove mode. GNATprove uses this flag to know
2581 -- when a body does not need to be analyzed. The value of this flag is
2582 -- only meaningful if Body_To_Inline is not Empty for the subprogram.
2584 -- Is_Instantiated (Flag126)
2585 -- Defined in generic packages and generic subprograms. Set if the unit
2586 -- is instantiated from somewhere in the extended main source unit. This
2587 -- flag is used to control warnings about the unit being uninstantiated.
2588 -- Also set in a package that is used as an actual for a generic package
2589 -- formal in an instantiation. Also set on a parent instance, in the
2590 -- instantiation of a child, which is implicitly declared in the parent.
2592 -- Is_Integer_Type (synthesized)
2593 -- Applies to all entities, true for integer types and subtypes
2595 -- Is_Interface (Flag186)
2596 -- Defined in record types and subtypes. Set to indicate that the current
2597 -- entity corresponds with an abstract interface. Because abstract
2598 -- interfaces are conceptually a special kind of abstract tagged types
2599 -- we represent them by means of tagged record types and subtypes
2600 -- marked with this attribute. This allows us to reuse most of the
2601 -- compiler support for abstract tagged types to implement interfaces
2602 -- (Ada 2005: AI-251).
2604 -- Is_Internal (Flag17)
2605 -- Defined in all entities. Set to indicate an entity created during
2606 -- semantic processing (e.g. an implicit type, or a temporary). The
2607 -- current uses of this flag are:
2609 -- 1) Internal entities (such as temporaries generated for the result
2610 -- of an inlined function call or dummy variables generated for the
2611 -- debugger). Set to indicate that they need not be initialized, even
2612 -- when scalars are initialized or normalized;
2614 -- 2) Predefined primitives of tagged types. Set to mark that they
2615 -- have specific properties: first they are primitives even if they
2616 -- are not defined in the type scope (the freezing point is not
2617 -- necessarily in the same scope), and second the predefined equality
2618 -- can be overridden by a user-defined equality, no body will be
2619 -- generated in this case.
2621 -- 3) Object declarations generated by the expander that are implicitly
2622 -- imported or exported so that they can be marked in Sprint output.
2624 -- 4) Internal entities in the list of primitives of tagged types that
2625 -- are used to handle secondary dispatch tables. These entities have
2626 -- also the attribute Interface_Alias.
2628 -- Is_Interrupt_Handler (Flag89)
2629 -- Defined in procedures. Set if a pragma Interrupt_Handler applies
2630 -- to the procedure. The procedure must be parameterless, and on all
2631 -- targets except AAMP it must be a protected procedure.
2633 -- Is_Intrinsic_Subprogram (Flag64)
2634 -- Defined in functions and procedures. It is set if a valid pragma
2635 -- Interface or Import is present for this subprogram specifying pragma
2636 -- Intrinsic. Valid means that the name and profile of the subprogram
2637 -- match the requirements of one of the recognized intrinsic subprograms
2638 -- (see package Sem_Intr for details). Note: the value of Convention for
2639 -- such an entity will be set to Convention_Intrinsic, but it is the
2640 -- setting of Is_Intrinsic_Subprogram, NOT simply having convention set
2641 -- to intrinsic, which causes intrinsic code to be generated.
2643 -- Is_Invariant_Procedure (Flag257)
2644 -- Defined in functions an procedures. Set for a generated invariant
2645 -- procedure to identify it easily in the
2647 -- Is_Itype (Flag91)
2648 -- Defined in all entities. Set to indicate that a type is an Itype,
2649 -- which means that the declaration for the type does not appear
2650 -- explicitly in the tree. Instead the backend will elaborate the type
2651 -- when it is first used. Has_Delayed_Freeze can be set for Itypes, and
2652 -- the meaning is that the first use (the one which causes the type to be
2653 -- defined) will be the freeze node. Note that an important restriction
2654 -- on Itypes is that the first use of such a type (the one that causes it
2655 -- to be defined) must be in the same scope as the type.
2657 -- Is_Known_Non_Null (Flag37)
2658 -- Defined in all entities. Relevant (and can be set) only for
2659 -- objects of an access type. It is set if the object is currently
2660 -- known to have a non-null value (meaning that no access checks
2661 -- are needed). The indication can for example come from assignment
2662 -- of an access parameter or an allocator whose value is known non-null.
2664 -- Note: this flag is set according to the sequential flow of the
2665 -- program, watching the current value of the variable. However, this
2666 -- processing can miss cases of changing the value of an aliased or
2667 -- constant object, so even if this flag is set, it should not be
2668 -- believed if the variable is aliased or volatile. It would be a
2669 -- little neater to avoid the flag being set in the first place in
2670 -- such cases, but that's trickier, and there is only one place that
2671 -- tests the value anyway.
2673 -- The flag is dynamically set and reset as semantic analysis and
2674 -- expansion proceeds. Its value is meaningless once the tree is
2675 -- fully constructed, since it simply indicates the last state.
2676 -- Thus this flag has no meaning to the backend.
2678 -- Is_Known_Null (Flag204)
2679 -- Defined in all entities. Relevant (and can be set ) only for
2680 -- objects of an access type. It is set if the object is currently known
2681 -- to have a null value (meaning that a dereference will surely raise
2682 -- constraint error exception). The indication can come from an
2683 -- assignment or object declaration.
2685 -- The comments above about sequential flow and aliased and volatile for
2686 -- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag.
2688 -- Is_Known_Valid (Flag170)
2689 -- Defined in all entities. Relevant for types (and subtype) and
2690 -- for objects (and enumeration literals) of a discrete type.
2692 -- The purpose of this flag is to implement the requirement stated
2693 -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
2694 -- values may not cause programs to become erroneous. See the function
2695 -- Checks.Expr_Known_Valid for further details. Note that the setting
2696 -- is conservative, in the sense that if the flag is set, it must be
2697 -- right. If the flag is not set, nothing is known about the validity.
2699 -- For enumeration literals, the flag is always set, since clearly
2700 -- an enumeration literal represents a valid value. Range checks
2701 -- where necessary will ensure that this valid value is appropriate.
2703 -- For objects, the flag indicates the state of knowledge about the
2704 -- current value of the object. This may be modified during expansion,
2705 -- and thus the final value is not relevant to the backend.
2707 -- For types and subtypes, the flag is set if all possible bit patterns
2708 -- of length Object_Size (i.e. Esize of the type) represent valid values
2709 -- of the type. In general for such tytpes, all values are valid, the
2710 -- only exception being the case where an object of the type has an
2711 -- explicit size that is greater than Object_Size.
2713 -- For non-discrete objects, the setting of the Is_Known_Valid flag is
2714 -- not defined, and is not relevant, since the considerations of the
2715 -- requirement in (RM 13.9.1(9-11)) do not apply.
2717 -- The flag is dynamically set and reset as semantic analysis and
2718 -- expansion proceeds. Its value is meaningless once the tree is
2719 -- fully constructed, since it simply indicates the last state.
2720 -- Thus this flag has no meaning to the backend.
2722 -- Is_Limited_Composite (Flag106)
2723 -- Defined in all entities. Set for composite types that have a limited
2724 -- component. Used to enforce the rule that operations on the composite
2725 -- type that depend on the full view of the component do not become
2726 -- visible until the immediate scope of the composite type itself
2729 -- Is_Limited_Interface (Flag197)
2730 -- Defined in record types and subtypes. True for interface types, if
2731 -- interface is declared limited, task, protected, or synchronized, or
2732 -- is derived from a limited interface.
2734 -- Is_Limited_Record (Flag25)
2735 -- Defined in all entities. Set to true for record (sub)types if the
2736 -- record is declared to be limited. Note that this flag is not set
2737 -- simply because some components of the record are limited.
2739 -- Is_Local_Anonymous_Access (Flag194)
2740 -- Defined in access types. Set for an anonymous access type to indicate
2741 -- that the type is created for a record component with an access
2742 -- definition, an array component, or (pre-Ada 2012) a standalone object.
2743 -- Such anonymous types have an accessibility level equal to that of the
2744 -- declaration in which they appear, unlike the anonymous access types
2745 -- that are created for access parameters, access discriminants, and
2746 -- (as of Ada 2012) stand-alone objects.
2748 -- Is_Machine_Code_Subprogram (Flag137)
2749 -- Defined in subprogram entities. Set to indicate that the subprogram
2750 -- is a machine code subprogram (i.e. its body includes at least one
2751 -- code statement). Also indicates that all necessary semantic checks
2752 -- as required by RM 13.8(3) have been performed.
2754 -- Is_Modular_Integer_Type (synthesized)
2755 -- Applies to all entities. True if entity is a modular integer type
2757 -- Is_Non_Static_Subtype (Flag109)
2758 -- Defined in all type and subtype entities. It is set in some (but not
2759 -- all) cases in which a subtype is known to be non-static. Before this
2760 -- flag was added, the computation of whether a subtype was static was
2761 -- entirely synthesized, by looking at the bounds, and the immediate
2762 -- subtype parent. However, this method does not work for some Itypes
2763 -- that have no parent set (and the only way to find the immediate
2764 -- subtype parent is to go through the tree). For now, this flag is set
2765 -- conservatively, i.e. if it is set then for sure the subtype is non-
2766 -- static, but if it is not set, then the type may or may not be static.
2767 -- Thus the test for a static subtype is that this flag is clear AND that
2768 -- the bounds are static AND that the parent subtype (if available to be
2769 -- tested) is static. Eventually we should make sure this flag is always
2770 -- set right, at which point, these comments can be removed, and the
2771 -- tests for static subtypes greatly simplified.
2773 -- Is_Null_Init_Proc (Flag178)
2774 -- Defined in procedure entities. Set for generated init proc procedures
2775 -- (used to initialize composite types), if the code for the procedure
2776 -- is null (i.e. is a return and nothing else). Such null initialization
2777 -- procedures are generated in case some client is compiled using the
2778 -- Initialize_Scalars pragma, generating a call to this null procedure,
2779 -- but there is no need to call such procedures within a compilation
2780 -- unit, and this flag is used to suppress such calls.
2782 -- Is_Null_State (synthesized)
2783 -- Applies to all entities, true for an abstract state declared with
2786 -- Is_Numeric_Type (synthesized)
2787 -- Applies to all entities, true for all numeric types and subtypes
2788 -- (integer, fixed, float).
2790 -- Is_Object (synthesized)
2791 -- Applies to all entities, true for entities representing objects,
2792 -- including generic formal parameters.
2794 -- Is_Obsolescent (Flag153)
2795 -- Defined in all entities. Set for any entity to which a valid pragma
2796 -- or aspect Obsolescent applies.
2798 -- Is_Only_Out_Parameter (Flag226)
2799 -- Defined in formal parameter entities. Set if this parameter is the
2800 -- only OUT parameter for this formal part. If there is more than one
2801 -- out parameter, or if there is some other IN OUT parameter then this
2802 -- flag is not set in any of them. Used in generation of warnings.
2804 -- Is_Ordinary_Fixed_Point_Type (synthesized)
2805 -- Applies to all entities, true for ordinary fixed point types and
2808 -- Is_Package_Or_Generic_Package (synthesized)
2809 -- Applies to all entities. True for packages and generic packages.
2810 -- False for all other entities.
2812 -- Is_Package_Body_Entity (Flag160)
2813 -- Defined in all entities. Set for entities defined at the top level
2814 -- of a package body. Used to control externally generated names.
2816 -- Is_Packed (Flag51) [implementation base type only]
2817 -- Defined in all type entities. This flag is set only for record and
2818 -- array types which have a packed representation. There are three
2819 -- cases which cause packing:
2821 -- 1. Explicit use of pragma Pack for an array of package components
2822 -- 2. Explicit use of pragma Pack to pack a record
2823 -- 4. Setting Component_Size of an array to a bit-packable value
2824 -- 3. Indexing an array with a non-standard enumeration type.
2826 -- For records, Is_Packed is always set if Has_Pragma_Pack is set,
2827 -- and can also be set on its own in a derived type which inherited
2828 -- its packed status.
2830 -- For arrays, Is_Packed is set if an array is bit packed (i.e. the
2831 -- component size is known at compile time and is 1-7, 9-15 or 17-31),
2832 -- or if the array has one or more index types that are enumeration
2833 -- types with non-standard representations (in GNAT, we store such
2834 -- arrays compactly, using the Pos of the enumeration type value).
2836 -- As for the case of records, Is_Packed can be set on its own for a
2837 -- derived type, with the same dual before/after freeze meaning.
2838 -- Is_Packed can also be set as the result of an explicit component
2839 -- size clause that specifies an appropriate component size.
2841 -- In the bit packed array case, Is_Bit_Packed_Array will be set in
2842 -- the bit packed case once the array type is frozen.
2844 -- Before an array type is frozen, Is_Packed will always be set if
2845 -- Has_Pragma_Pack is set. Before the freeze point, it is not possible
2846 -- to know the component size, since the component type is not frozen
2847 -- until the array type is frozen. Thus Is_Packed for an array type
2848 -- before it is frozen means that packed is required. Then if it turns
2849 -- out that the component size is not suitable for bit packing, the
2850 -- Is_Packed flag gets turned off.
2852 -- Is_Packed_Array (synth)
2853 -- Applies to all entities, true if entity is for a packed array.
2855 -- Is_Packed_Array_Impl_Type (Flag138)
2856 -- Defined in all entities. This flag is set on the entity for the type
2857 -- used to implement a packed array (either a modular type, or a subtype
2858 -- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
2859 -- if the type appears in the Packed_Array_Impl_Type field of some other
2860 -- entity. It is used by the backend to activate the special processing
2861 -- for such types (unchecked conversions that would not otherwise be
2862 -- allowed are allowed for such types). If Is_Packed_Array_Impl_Type is
2863 -- set in an entity, then the Original_Array_Type field of this entity
2864 -- points to the array type for which this is the Packed_Array_Impl_Type.
2866 -- Is_Potentially_Use_Visible (Flag9)
2867 -- Defined in all entities. Set if entity is potentially use visible,
2868 -- i.e. it is defined in a package that appears in a currently active
2869 -- use clause (RM 8.4(8)). Note that potentially use visible entities
2870 -- are not necessarily use visible (RM 8.4(9-11)).
2872 -- Is_Predicate_Function (Flag255)
2873 -- Present in functions and procedures. Set for generated predicate
2876 -- Is_Predicate_Function_M (Flag256)
2877 -- Present in functions and procedures. Set for special version of
2878 -- predicate function generated for use in membership tests, where
2879 -- raise expressions are transformed to return False.
2881 -- Is_Preelaborated (Flag59)
2882 -- Defined in all entities, set in E_Package and E_Generic_Package
2883 -- entities to which a pragma Preelaborate is applied, and also in
2884 -- all entities within such packages. Note that the fact that this
2885 -- flag is set does not necesarily mean that no elaboration code is
2886 -- generated for the package.
2888 -- Is_Primitive (Flag218)
2889 -- Defined in overloadable entities and in generic subprograms. Set to
2890 -- indicate that this is a primitive operation of some type, which may
2891 -- be a tagged type or an untagged type. Used to verify overriding
2892 -- indicators in bodies.
2894 -- Is_Primitive_Wrapper (Flag195)
2895 -- Defined in functions and procedures created by the expander to serve
2896 -- as an indirection mechanism to overriding primitives of concurrent
2897 -- types, entries and protected procedures.
2899 -- Is_Prival (synthesized)
2900 -- Applies to all entities, true for renamings of private protected
2901 -- components. Such entities appear as constants or variables.
2903 -- Is_Private_Composite (Flag107)
2904 -- Defined in composite types that have a private component. Used to
2905 -- enforce the rule that operations on the composite type that depend
2906 -- on the full view of the component, do not become visible until the
2907 -- immediate scope of the composite type itself (7.3.1 (5)). Both this
2908 -- flag and Is_Limited_Composite are needed.
2910 -- Is_Private_Descendant (Flag53)
2911 -- Defined in entities that can represent library units (packages,
2912 -- functions, procedures). Set if the library unit is itself a private
2913 -- child unit, or if it is the descendent of a private child unit.
2915 -- Is_Private_Primitive (Flag245)
2916 -- Defined in subprograms. Set if the operation is a primitive of a
2917 -- tagged type (procedure or function dispatching on result) whose
2918 -- full view has not been seen. Used in particular for primitive
2919 -- subprograms of a synchronized type declared between the two views
2920 -- of the type, so that the wrapper built for such a subprogram can
2921 -- be given the proper signature.
2923 -- Is_Private_Type (synthesized)
2924 -- Applies to all entities, true for private types and subtypes,
2925 -- as well as for record with private types as subtypes
2927 -- Is_Processed_Transient (Flag252)
2928 -- Defined in variables, loop parameters, and constants, including the
2929 -- loop parameters of generalized iterators. Set when a transient object
2930 -- needs to be finalized and has already been processed by the transient
2931 -- scope machinery. This flag signals the general finalization mechanism
2932 -- to ignore the transient object.
2934 -- Is_Protected_Component (synthesized)
2935 -- Applicable to all entities, true if the entity denotes a private
2936 -- component of a protected type.
2938 -- Is_Protected_Interface (synthesized)
2939 -- Defined in types that are interfaces. True if interface is declared
2940 -- protected, or is derived from protected interfaces.
2942 -- Is_Protected_Type (synthesized)
2943 -- Applies to all entities, true for protected types and subtypes
2945 -- Is_Public (Flag10)
2946 -- Defined in all entities. Set to indicate that an entity defined in
2947 -- one compilation unit can be referenced from other compilation units.
2948 -- If this reference causes a reference in the generated code, for
2949 -- example in the case of a variable name, then the backend will generate
2950 -- an appropriate external name for use by the linker.
2952 -- Is_Protected_Record_Type (synthesized)
2953 -- Applies to all entities, true if Is_Concurrent_Record_Type is true and
2954 -- Corresponding_Concurrent_Type is a protected type.
2957 -- Defined in all entities. Set in all entities of a unit to which a
2958 -- pragma Pure is applied except for non-intrinsic imported subprograms,
2959 -- and also set for the entity of the unit itself. In addition, this
2960 -- flag may be set for any other functions or procedures that are known
2961 -- to be side effect free, so in the case of subprograms, the Is_Pure
2962 -- flag may be used by the optimizer to imply that it can assume freedom
2963 -- from side effects (other than those resulting from assignment to out
2964 -- parameters, or to objects designated by access parameters).
2966 -- Is_Pure_Unit_Access_Type (Flag189)
2967 -- Defined in access type and subtype entities. Set if the type or
2968 -- subtype appears in a pure unit. Used to give an error message at
2969 -- freeze time if the access type has a storage pool.
2971 -- Is_RACW_Stub_Type (Flag244)
2972 -- Defined in all types, true for the stub types generated for remote
2973 -- access-to-class-wide types.
2975 -- Is_Raised (Flag224)
2976 -- Defined in exception entities. Set if the entity is referenced by a
2977 -- a raise statement.
2979 -- Is_Real_Type (synthesized)
2980 -- Applies to all entities, true for real types and subtypes
2982 -- Is_Record_Type (synthesized)
2983 -- Applies to all entities, true for record types and subtypes,
2984 -- includes class-wide types and subtypes (which are also records)
2986 -- Is_Remote_Call_Interface (Flag62)
2987 -- Defined in all entities. Set in E_Package and E_Generic_Package
2988 -- entities to which a pragma Remote_Call_Interface is applied, and
2989 -- also on entities declared in the visible part of such a package.
2991 -- Is_Remote_Types (Flag61)
2992 -- Defined in all entities. Set in E_Package and E_Generic_Package
2993 -- entities to which a pragma Remote_Types is applied, and also on
2994 -- entities declared in the visible part of the spec of such a package.
2995 -- Also set for types which are generic formal types to which the
2996 -- pragma Remote_Access_Type applies.
2998 -- Is_Renaming_Of_Object (Flag112)
2999 -- Defined in all entities, set only for a variable or constant for
3000 -- which the Renamed_Object field is non-empty and for which the
3001 -- renaming is handled by the front end, by macro substitution of
3002 -- a copy of the (evaluated) name tree whereever the variable is used.
3004 -- Is_Return_Object (Flag209)
3005 -- Defined in all object entities. True if the object is the return
3006 -- object of an extended_return_statement; False otherwise.
3008 -- Is_Safe_To_Reevaluate (Flag249)
3009 -- Defined in all entities. Set in variables that are initialized by
3010 -- means of an assignment statement. When initialized their contents
3011 -- never change and hence they can be seen by the backend as constants.
3012 -- See also Is_True_Constant.
3014 -- Is_Scalar_Type (synthesized)
3015 -- Applies to all entities, true for scalar types and subtypes
3017 -- Is_Shared_Passive (Flag60)
3018 -- Defined in all entities. Set in E_Package and E_Generic_Package
3019 -- entities to which a pragma Shared_Passive is applied, and also in
3020 -- all entities within such packages.
3022 -- Is_Standard_Character_Type (synthesized)
3023 -- Applies to all entities, true for types and subtypes whose root type
3024 -- is one of the standard character types (Character, Wide_Character, or
3025 -- Wide_Wide_Character).
3027 -- Is_Standard_String_Type (synthesized)
3028 -- Applies to all entities, true for types and subtypes whose root
3029 -- type is one of the standard string types (String, Wide_String, or
3030 -- Wide_Wide_String).
3032 -- Is_Static_Type (Flag281)
3033 -- Defined in entities. Only set for (sub)types. If set, indicates that
3034 -- the type is known to be a static type (defined as a discrete type with
3035 -- static bounds, a record all of whose component types are static types,
3036 -- or an array, all of whose bounds are of a static type, and also have
3037 -- a component type that is a static type). See Set_Uplevel_Type for more
3038 -- information on how this flag is used. Note that if Is_Static_Type is
3039 -- True, then it is never the case that the Has_Uplevel_Reference flag is
3040 -- set for the same type.
3042 -- Is_Statically_Allocated (Flag28)
3043 -- Defined in all entities. This can only be set for exception,
3044 -- variable, constant, and type/subtype entities. If the flag is set,
3045 -- then the variable or constant must be allocated statically rather
3046 -- than on the local stack frame. For exceptions, the meaning is that
3047 -- the exception data should be allocated statically (and indeed this
3048 -- flag is always set for exceptions, since exceptions do not have
3049 -- local scope). For a type, the meaning is that the type must be
3050 -- elaborated at the global level rather than locally. No type marked
3051 -- with this flag may depend on a local variable, or on any other type
3052 -- which does not also have this flag set to True. For a variable or
3053 -- or constant, if the flag is set, then the type of the object must
3054 -- either be declared at the library level, or it must also have the
3055 -- flag set (since to allocate the object statically, its type must
3056 -- also be elaborated globally).
3058 -- Is_String_Type (synthesized)
3059 -- Applies to all type entities. Determines if the given type is a
3060 -- string type, i.e. it is directly a string type or string subtype,
3061 -- or a string slice type, or an array type with one dimension and a
3062 -- component type that is a character type.
3064 -- Is_Subprogram (synthesized)
3065 -- Applies to all entities, true for function, procedure and operator
3068 -- Is_Subprogram_Or_Generic_Subprogram
3069 -- Applies to all entities, true for function procedure and operator
3070 -- entities, and also for the corresponding generic entities.
3072 -- Is_Synchronized_Interface (synthesized)
3073 -- Defined in types that are interfaces. True if interface is declared
3074 -- synchronized, task, or protected, or is derived from a synchronized
3078 -- Defined in E_Component and E_Constant entities. For regular tagged
3079 -- type this flag is set on the tag component (whose name is Name_uTag).
3080 -- For CPP_Class tagged types, this flag marks the pointer to the main
3081 -- vtable (i.e. the one to be extended by derivation).
3083 -- Is_Tagged_Type (Flag55)
3084 -- Defined in all entities. Set for an entity that is a tagged type.
3086 -- Is_Task_Interface (synthesized)
3087 -- Defined in types that are interfaces. True if interface is declared as
3088 -- a task interface, or if it is derived from task interfaces.
3090 -- Is_Task_Record_Type (synthesized)
3091 -- Applies to all entities. True if Is_Concurrent_Record_Type
3092 -- Corresponding_Concurrent_Type is a task type.
3094 -- Is_Task_Type (synthesized)
3095 -- Applies to all entities. True for task types and subtypes
3097 -- Is_Thunk (Flag225)
3098 -- Defined in all entities. True for subprograms that are thunks: that is
3099 -- small subprograms built by the expander for tagged types that cover
3100 -- interface types. As part of the runtime call to an interface, thunks
3101 -- displace the pointer to the object (pointer named "this" in the C++
3102 -- terminology) from a secondary dispatch table to the primary dispatch
3103 -- table associated with a given tagged type; if the thunk is a function
3104 -- that returns an object which covers an interface type then the thunk
3105 -- displaces the pointer to the object from the primary dispatch table to
3106 -- the secondary dispatch table associated with the interface type. Set
3107 -- by Expand_Interface_Thunk and used by Expand_Call to handle extra
3108 -- actuals associated with accessibility level.
3110 -- Is_Trivial_Subprogram (Flag235)
3111 -- Defined in all entities. Set in subprograms where either the body
3112 -- consists of a single null statement, or the first or only statement
3113 -- of the body raises an exception. This is used for suppressing certain
3114 -- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details.
3116 -- Is_True_Constant (Flag163)
3117 -- Defined in all entities for constants and variables. Set in constants
3118 -- and variables which have an initial value specified but which are
3119 -- never assigned, partially or in the whole. For variables, it means
3120 -- that the variable was initialized but never modified, and hence can be
3121 -- treated as a constant by the code generator. For a constant, it means
3122 -- that the constant was not modified by generated code (e.g. to set a
3123 -- discriminant in an init proc). Assignments by user or generated code
3124 -- will reset this flag. See also Is_Safe_To_Reevaluate.
3126 -- Is_Type (synthesized)
3127 -- Applies to all entities, true for a type entity
3129 -- Is_Unchecked_Union (Flag117) [implementation base type only]
3130 -- Defined in all entities. Set only in record types to which the
3131 -- pragma Unchecked_Union has been validly applied.
3133 -- Is_Underlying_Record_View (Flag246) [base type only]
3134 -- Defined in all entities. Set only in record types that represent the
3135 -- underlying record view. This view is built for derivations of types
3136 -- with unknown discriminants; it is a record with the same structure
3137 -- as its corresponding record type, but whose parent is the full view
3138 -- of the parent in the original type extension.
3140 -- Is_Unimplemented (Flag284)
3141 -- Defined in all entities. Set for any entity to which a valid pragma
3142 -- or aspect Unimplemented applies.
3144 -- Is_Unsigned_Type (Flag144)
3145 -- Defined in all types, but can be set only for discrete and fixed-point
3146 -- type and subtype entities. This flag is only valid if the entity is
3147 -- frozen. If set it indicates that the representation is known to be
3148 -- unsigned (i.e. that no negative values appear in the range). This is
3149 -- normally just a reflection of the lower bound of the subtype or base
3150 -- type, but there is one case in which the setting is non-obvious,
3151 -- namely the case of an unsigned subtype of a signed type from which
3152 -- a further subtype is obtained using variable bounds. This further
3153 -- subtype is still unsigned, but this cannot be determined by looking
3154 -- at its bounds or the bounds of the corresponding base type.
3156 -- Is_Uplevel_Referenced_Entity (Flag283)
3157 -- Defined in all entities. Used when unnesting subprograms to indicate
3158 -- that an entity is locally defined within a subprogram P, and there is
3159 -- a reference to the entity within a subprogram nested within P (at any
3160 -- depth). Set for uplevel referenced objects (variables, constants and
3161 -- loop parameters), and also for upreferenced dynamic types, including
3162 -- the cases where the reference is implicit (e.g. the type of an array
3163 -- used for computing the location of an element in an array. This is
3164 -- used internally in Exp_Unst, see this package for further details.
3165 -- Note that this is similar to the Has_Uplevel_Reference flag which
3166 -- is used in the VM case but we prefer to keep the two cases entirely
3167 -- separated, so that the VM usage is not disturbed by work on the
3168 -- Unnesting_Subprograms mode.
3170 -- Is_Valued_Procedure (Flag127)
3171 -- Defined in procedure entities. Set if an Import_Valued_Procedure
3172 -- or Export_Valued_Procedure pragma applies to the procedure entity.
3174 -- Is_Visible_Formal (Flag206)
3175 -- Defined in all entities. Set for instances of the formals of a
3176 -- formal package. Indicates that the entity must be made visible in the
3177 -- body of the instance, to reproduce the visibility of the generic.
3178 -- This simplifies visibility settings in instance bodies.
3180 -- Is_Visible_Lib_Unit (Flag116)
3181 -- Defined in all (root or child) library unit entities. Once compiled,
3182 -- library units remain chained to the entities in the parent scope, and
3183 -- a separate flag must be used to indicate whether the names are visible
3184 -- by selected notation, or not.
3186 -- Is_Volatile (Flag16)
3187 -- Defined in all type entities, and also in constants, components and
3188 -- variables. Set if a pragma Volatile applies to the entity. Also set
3189 -- if pragma Shared or pragma Atomic applies to entity. In the case of
3190 -- private or incomplete types, this flag is set in both the private
3191 -- and full view. The flag is not set reliably on private subtypes,
3192 -- and is always retrieved from the base type (but this is not a base-
3193 -- type-only attribute because it applies to other entities). Note that
3194 -- the backend should use Treat_As_Volatile, rather than Is_Volatile
3195 -- to indicate code generation requirements for volatile variables.
3196 -- Similarly, any front end test which is concerned with suppressing
3197 -- optimizations on volatile objects should test Treat_As_Volatile
3198 -- rather than testing this flag.
3200 -- Is_Volatile_Full_Access (Flag285)
3201 -- Defined in all type entities, and also in constants, components, and
3202 -- variables. Set if a pragma Volatile_Full_Access applies to the entity.
3203 -- In the case of private and incomplete types, this flag is set in
3204 -- both the partial view and the full view.
3206 -- Is_Wrapper_Package (synthesized)
3207 -- Defined in package entities. Indicates that the package has been
3208 -- created as a wrapper for a subprogram instantiation.
3210 -- Itype_Printed (Flag202)
3211 -- Defined in all type and subtype entities. Set in Itypes if the Itype
3212 -- has been printed by Sprint. This is used to avoid printing an Itype
3215 -- Kill_Elaboration_Checks (Flag32)
3216 -- Defined in all entities. Set by the expander to kill elaboration
3217 -- checks which are known not to be needed. Equivalent in effect to
3218 -- the use of pragma Suppress (Elaboration_Checks) for that entity
3219 -- except that the effect is permanent and cannot be undone by a
3220 -- subsequent pragma Unsuppress.
3222 -- Kill_Range_Checks (Flag33)
3223 -- Defined in all entities. Equivalent in effect to the use of pragma
3224 -- Suppress (Range_Checks) for that entity except that the result is
3225 -- permanent and cannot be undone by a subsequent pragma Unsuppress.
3226 -- This is currently only used in one odd situation in Sem_Ch3 for
3227 -- record types, and it would be good to get rid of it???
3229 -- Known_To_Have_Preelab_Init (Flag207)
3230 -- Defined in all type and subtype entities. If set, then the type is
3231 -- known to have preelaborable initialization. In the case of a partial
3232 -- view of a private type, it is only possible for this to be set if a
3233 -- pragma Preelaborable_Initialization is given for the type. For other
3234 -- types, it is never set if the type does not have preelaborable
3235 -- initialization, it may or may not be set if the type does have
3236 -- preelaborable initialization.
3238 -- Last_Aggregate_Assignment (Node30)
3239 -- Applies to controlled constants and variables initialized by an
3240 -- aggregate. Points to the last statement associated with the expansion
3241 -- of the aggregate. The attribute is used by the finalization machinery
3242 -- when marking an object as successfully initialized.
3244 -- Last_Assignment (Node26)
3245 -- Defined in entities for variables, and OUT or IN OUT formals. Set for
3246 -- a local variable or formal to point to the left side of an assignment
3247 -- statement assigning a value to the variable. Cleared if the value of
3248 -- the entity is referenced. Used to warn about dubious assignment
3249 -- statements whose value is not used.
3251 -- Last_Entity (Node20)
3252 -- Defined in all entities which act as scopes to which a list of
3253 -- associated entities is attached (blocks, class subtypes and types,
3254 -- entries, functions, loops, packages, procedures, protected objects,
3255 -- record types and subtypes, private types, task types and subtypes).
3256 -- Points to the last entry in the list of associated entities chained
3257 -- through the Next_Entity field. Empty if no entities are chained.
3259 -- Last_Formal (synthesized)
3260 -- Applies to subprograms and subprogram types, and also in entries
3261 -- and entry families. Returns last formal of the subprogram or entry.
3262 -- The formals are the first entities declared in a subprogram or in
3263 -- a subprogram type (the designated type of an Access_To_Subprogram
3264 -- definition) or in an entry.
3266 -- Limited_View (Node23)
3267 -- Defined in non-generic package entities that are not instances. Bona
3268 -- fide package with the limited-view list through the first_entity and
3269 -- first_private attributes. The elements of this list are the shadow
3270 -- entities created for the types and local packages that are declared
3271 -- in a package appearing in a limited_with clause (Ada 2005: AI-50217).
3273 -- Linker_Section_Pragma (Node33)
3274 -- Present in constant, variable, type and subprogram entities. Points
3275 -- to a linker section pragma that applies to the entity, or is Empty if
3276 -- no such pragma applies. Note that for constants and variables, this
3277 -- field may be set as a result of a linker section pragma applied to the
3278 -- type of the object.
3280 -- Lit_Indexes (Node18)
3281 -- Defined in enumeration types and subtypes. Non-empty only for the
3282 -- case of an enumeration root type, where it contains the entity for
3283 -- the generated indexes entity. See unit Exp_Imgv for full details of
3284 -- the nature and use of this entity for implementing the Image and
3285 -- Value attributes for the enumeration type in question.
3287 -- Lit_Strings (Node16)
3288 -- Defined in enumeration types and subtypes. Non-empty only for the
3289 -- case of an enumeration root type, where it contains the entity for
3290 -- the literals string entity. See unit Exp_Imgv for full details of
3291 -- the nature and use of this entity for implementing the Image and
3292 -- Value attributes for the enumeration type in question.
3294 -- Low_Bound_Tested (Flag205)
3295 -- Defined in all entities. Currently this can only be set for formal
3296 -- parameter entries of a standard unconstrained one-dimensional array
3297 -- or string type. Indicates that an explicit test of the low bound of
3298 -- the formal appeared in the code, e.g. in a pragma Assert. If this
3299 -- flag is set, warnings about assuming the index low bound to be one
3302 -- Machine_Radix_10 (Flag84)
3303 -- Defined in decimal types and subtypes, set if the Machine_Radix is 10,
3304 -- as the result of the specification of a machine radix representation
3305 -- clause. Note that it is possible for this flag to be set without
3306 -- having Has_Machine_Radix_Clause True. This happens when a type is
3307 -- derived from a type with a clause present.
3309 -- Master_Id (Node17)
3310 -- Defined in access types and subtypes. Empty unless Has_Task is set for
3311 -- the designated type, in which case it points to the entity for the
3312 -- Master_Id for the access type master. Also set for access-to-limited-
3313 -- class-wide types whose root may be extended with task components, and
3314 -- for access-to-limited-interfaces because they can be used to reference
3315 -- tasks implementing such interface.
3317 -- Materialize_Entity (Flag168)
3318 -- Defined in all entities. Set only for renamed obects which should be
3319 -- materialized for debugging purposes. This means that a memory location
3320 -- containing the renamed address should be allocated. This is needed so
3321 -- that the debugger can find the entity.
3323 -- May_Inherit_Delayed_Rep_Aspects (Flag262)
3324 -- Defined in all entities for types and subtypes. Set if the type is
3325 -- derived from a type which has delayed rep aspects (marked by the flag
3326 -- Has_Delayed_Rep_Aspects being set). In this case, at the freeze point
3327 -- for the derived type we know that the parent type is frozen, and if
3328 -- a given attribute has not been set for the derived type, we copy the
3329 -- value from the parent type. See Freeze.Inherit_Delayed_Rep_Aspects.
3331 -- Mechanism (Uint8) (returned as Mechanism_Type)
3332 -- Defined in functions and non-generic formal parameters. Indicates
3333 -- the mechanism to be used for the function return or for the formal
3334 -- parameter. See full description in the spec of Sem_Mech. This field
3335 -- is also set (to the default value of zero = Default_Mechanism) in a
3336 -- subprogram body entity but not used in this context.
3338 -- Modulus (Uint17) [base type only]
3339 -- Defined in modular types. Contains the modulus. For the binary case,
3340 -- this will be a power of 2, but if Non_Binary_Modulus is set, then it
3341 -- will not be a power of 2.
3343 -- Must_Be_On_Byte_Boundary (Flag183)
3344 -- Defined in entities for types and subtypes. Set if objects of the type
3345 -- must always be allocated on a byte boundary (more accurately a storage
3346 -- unit boundary). The front end checks that component clauses respect
3347 -- this rule, and the backend ensures that record packing does not
3348 -- violate this rule. Currently the flag is set only for packed arrays
3349 -- longer than 64 bits where the component size is not a power of 2.
3351 -- Must_Have_Preelab_Init (Flag208)
3352 -- Defined in entities for types and subtypes. Set in the full type of a
3353 -- private type or subtype if a pragma Has_Preelaborable_Initialization
3354 -- is present for the private type. Used to check that the full type has
3355 -- preelaborable initialization at freeze time (this has to be deferred
3356 -- to the freeze point because of the rule about overriding Initialize).
3358 -- Needs_Debug_Info (Flag147)
3359 -- Defined in all entities. Set if the entity requires normal debugging
3360 -- information to be generated. This is true of all entities that have
3361 -- Comes_From_Source set, and also transitively for entities associated
3362 -- with such components (e.g. their types). It is true for all entities
3363 -- in Debug_Generated_Code mode (-gnatD switch). This is the flag that
3364 -- the backend should check to determine whether or not to generate
3365 -- debugging information for an entity. Note that callers should always
3366 -- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info,
3367 -- so that the flag is set properly on subsidiary entities.
3369 -- Needs_No_Actuals (Flag22)
3370 -- Defined in callable entities (subprograms, entries, access to
3371 -- subprograms) which can be called without actuals because all of
3372 -- their formals (if any) have default values. This flag simplifies the
3373 -- resolution of the syntactic ambiguity involving a call to these
3374 -- entities when the return type is an array type, and a call can be
3375 -- interpreted as an indexing of the result of the call. It is also
3376 -- used to resolve various cases of entry calls.
3378 -- Needs_Typedef (Flag286)
3379 -- Defined for all types and subtypes. Set if it is essential to generate
3380 -- a typedef when we are generating C code from Cprint. Normally we
3381 -- generate typedef's only for source entities, and not for internally
3382 -- generated types, but there are cases, notably the AREC types generated
3383 -- in Exp_Unst when we are unnesting subprograms where we must generate
3384 -- typedef's for non-source types.
3386 -- Never_Set_In_Source (Flag115)
3387 -- Defined in all entities, but can be set only for variables and
3388 -- parameters. This flag is set if the object is never assigned a value
3389 -- in user source code, either by assignment or by being used as an out
3390 -- or in out parameter. Note that this flag is not reset from using an
3391 -- initial value, so if you want to test for this case as well, test the
3392 -- Has_Initial_Value flag also.
3394 -- This flag is only for the purposes of issuing warnings, it must not
3395 -- be used by the code generator to indicate that the variable is in
3396 -- fact a constant, since some assignments in generated code do not
3397 -- count (for example, the call to an init proc to assign some but
3398 -- not all of the fields in a partially initialized record). The code
3399 -- generator should instead use the flag Is_True_Constant.
3401 -- For the purposes of this warning, the default assignment of access
3402 -- variables to null is not considered the assignment of a value (so
3403 -- the warning can be given for code that relies on this initial null
3404 -- value when no other value is ever set).
3406 -- In variables and out parameters, if this flag is set after full
3407 -- processing of the corresponding declarative unit, it indicates that
3408 -- the variable or parameter was never set, and a warning message can
3411 -- Note: this flag is initially set, and then cleared on encountering
3412 -- any construct that might conceivably legitimately set the value.
3413 -- Thus during the analysis of a declarative region and its associated
3414 -- statement sequence, the meaning of the flag is "not set yet", and
3415 -- once this analysis is complete the flag means "never assigned".
3417 -- Note: for variables appearing in package declarations, this flag is
3418 -- never set. That is because there is no way to tell if some client
3419 -- modifies the variable (or, in the case of variables in the private
3420 -- part, if some child unit modifies the variables).
3422 -- Note: in the case of renamed objects, the flag must be set in the
3423 -- ultimate renamed object. Clients noting a possible modification
3424 -- should use the Note_Possible_Modification procedure in Sem_Util
3425 -- rather than Set_Never_Set_In_Source precisely to deal properly with
3426 -- the renaming possibility.
3428 -- Next_Component (synthesized)
3429 -- Applies to record components. Returns the next component by following
3430 -- the chain of declared entities until one is found which corresponds to
3431 -- a component (Ekind is E_Component). Any internal types generated from
3432 -- the subtype indications of the record components are skipped. Returns
3433 -- Empty if no more components.
3435 -- Next_Component_Or_Discriminant (synthesized)
3436 -- Similar to Next_Component, but includes components and discriminants
3437 -- so the input can have either E_Component or E_Discriminant, and the
3438 -- same is true for the result. Returns Empty if no more components or
3439 -- discriminants in the record.
3441 -- Next_Discriminant (synthesized)
3442 -- Applies to discriminants returned by First/Next_Discriminant. Returns
3443 -- the next language-defined (ie: perhaps non-girder) discriminant by
3444 -- following the chain of declared entities as long as the kind of the
3445 -- entity corresponds to a discriminant. Note that the discriminants
3446 -- might be the only components of the record. Returns Empty if there
3447 -- are no more discriminants.
3449 -- Next_Entity (Node2)
3450 -- Defined in all entities. The entities of a scope are chained, with
3451 -- the head of the list being in the First_Entity field of the scope
3452 -- entity. All entities use the Next_Entity field as a forward pointer
3453 -- for this list, with Empty indicating the end of the list. Since this
3454 -- field is in the base part of the entity, the access routines for this
3455 -- field are in Sinfo.
3457 -- Next_Formal (synthesized)
3458 -- Applies to the entity for a formal parameter. Returns the next formal
3459 -- parameter of the subprogram or subprogram type. Returns Empty if there
3460 -- are no more formals.
3462 -- Next_Formal_With_Extras (synthesized)
3463 -- Applies to the entity for a formal parameter. Returns the next
3464 -- formal parameter of the subprogram or subprogram type. Returns
3465 -- Empty if there are no more formals. The list returned includes
3466 -- all the extra formals (see description of Extra_Formal field)
3468 -- Next_Index (synthesized)
3469 -- Applies to array types and subtypes and to string types and
3470 -- subtypes. Yields the next index. The first index is obtained by
3471 -- using the First_Index attribute, and then subsequent indexes are
3472 -- obtained by applying Next_Index to the previous index. Empty is
3473 -- returned to indicate that there are no more indexes. Note that
3474 -- unlike most attributes in this package, Next_Index applies to
3475 -- nodes for the indexes, not to entities.
3477 -- Next_Inlined_Subprogram (Node12)
3478 -- Defined in subprograms. Used to chain inlined subprograms used in
3479 -- the current compilation, in the order in which they must be compiled
3480 -- by the backend to insure that all inlinings are performed.
3482 -- Next_Literal (synthesized)
3483 -- Applies to enumeration literals, returns the next literal, or
3484 -- Empty if applied to the last literal. This is actually a synonym
3485 -- for Next, but its use is preferred in this context.
3487 -- No_Dynamic_Predicate_On_Actual (Flag276)
3488 -- Defined in discrete types. Set for generic formal types that are used
3489 -- in loops and quantified expressions. The corresponing actual cannot
3490 -- have dynamic predicates.
3492 -- No_Pool_Assigned (Flag131) [root type only]
3493 -- Defined in access types. Set if a storage size clause applies to the
3494 -- variable with a static expression value of zero. This flag is used to
3495 -- generate errors if any attempt is made to allocate or free an instance
3496 -- of such an access type. This is set only in the root type, since
3497 -- derived types must have the same pool.
3499 -- No_Predicate_On_Actual (Flag275)
3500 -- Defined in discrete types. Set for generic formal types that are used
3501 -- in the spec of a generic package, in constructs that forbid discrete
3502 -- types with predicates.
3504 -- No_Return (Flag113)
3505 -- Defined in all entities. Always false except in the case of procedures
3506 -- and generic procedures for which a pragma No_Return is given.
3508 -- No_Strict_Aliasing (Flag136) [base type only]
3509 -- Defined in access types. Set to direct the backend to avoid any
3510 -- optimizations based on an assumption about the aliasing status of
3511 -- objects designated by the access type. For the case of the gcc
3512 -- backend, the effect is as though all references to objects of
3513 -- the type were compiled with -fno-strict-aliasing. This flag is
3514 -- set if an unchecked conversion with the access type as a target
3515 -- type occurs in the same source unit as the declaration of the
3516 -- access type, or if an explicit pragma No_Strict_Aliasing applies.
3518 -- No_Tagged_Streams_Pragma (Node32)
3519 -- Present in all subtype and type entities. Set for tagged types and
3520 -- subtypes (i.e. entities with Is_Tagged_Type set True) if a valid
3521 -- pragma/aspect applies to the type.
3523 -- Non_Binary_Modulus (Flag58) [base type only]
3524 -- Defined in all subtype and type entities. Set for modular integer
3525 -- types if the modulus value is other than a power of 2.
3527 -- Non_Limited_View (Node19)
3528 -- Defined in abstract states and incomplete types that act as shadow
3529 -- entities created when analysing a limited with clause (Ada 2005:
3530 -- AI-50217). Points to the defining entity of the original declaration.
3532 -- Nonzero_Is_True (Flag162) [base type only]
3533 -- Defined in enumeration types. Set if any non-zero value is to be
3534 -- interpreted as true. Currently this is set for derived Boolean
3535 -- types which have a convention of C, C++ or Fortran.
3537 -- Normalized_First_Bit (Uint8)
3538 -- Defined in components and discriminants. Indicates the normalized
3539 -- value of First_Bit for the component, i.e. the offset within the
3540 -- lowest addressed storage unit containing part or all of the field.
3541 -- Set to No_Uint if no first bit position is assigned yet.
3543 -- Normalized_Position (Uint14)
3544 -- Defined in components and discriminants. Indicates the normalized
3545 -- value of Position for the component, i.e. the offset in storage
3546 -- units from the start of the record to the lowest addressed storage
3547 -- unit containing part or all of the field.
3549 -- Normalized_Position_Max (Uint10)
3550 -- Defined in components and discriminants. For almost all cases, this
3551 -- is the same as Normalized_Position. The one exception is for the case
3552 -- of a discriminated record containing one or more arrays whose length
3553 -- depends on discriminants. In this case, the Normalized_Position_Max
3554 -- field represents the maximum possible value of Normalized_Position
3555 -- assuming min/max values for discriminant subscripts in all fields.
3556 -- This is used by Layout in front end layout mode to properly computed
3557 -- the maximum size such records (needed for allocation purposes when
3558 -- there are default discriminants, and also for the 'Size value).
3560 -- Number_Dimensions (synthesized)
3561 -- Applies to array types and subtypes. Returns the number of dimensions
3562 -- of the array type or subtype as a value of type Pos.
3564 -- Number_Entries (synthesized)
3565 -- Applies to concurrent types. Returns the number of entries that are
3566 -- declared within the task or protected definition for the type.
3568 -- Number_Formals (synthesized)
3569 -- Applies to subprograms and subprogram types. Yields the number of
3570 -- formals as a value of type Pos.
3572 -- OK_To_Rename (Flag247)
3573 -- Defined only in entities for variables. If this flag is set, it
3574 -- means that if the entity is used as the initial value of an object
3575 -- declaration, the object declaration can be safely converted into a
3576 -- renaming to avoid an extra copy. This is set for variables which are
3577 -- generated by the expander to hold the result of evaluating some
3578 -- expression. Most notably, the local variables used to store the result
3579 -- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It
3580 -- is only worth setting this flag for composites, since for primitive
3581 -- types, it is cheaper to do the copy.
3583 -- OK_To_Reorder_Components (Flag239) [base type only]
3584 -- Defined in record types. Set if the backend is permitted to reorder
3585 -- the components. If not set, the record must be layed out in the order
3586 -- in which the components are declared textually. Currently this flag
3587 -- can only be set by debug switches.
3589 -- Optimize_Alignment_Space (Flag241)
3590 -- Defined in type, subtype, variable, and constant entities. This
3591 -- flag records that the type or object is to be layed out in a manner
3592 -- consistent with Optimize_Alignment (Space) mode. The compiler and
3593 -- binder ensure a consistent view of any given type or object. If pragma
3594 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3595 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3597 -- Optimize_Alignment_Time (Flag242)
3598 -- Defined in type, subtype, variable, and constant entities. This
3599 -- flag records that the type or object is to be layed out in a manner
3600 -- consistent with Optimize_Alignment (Time) mode. The compiler and
3601 -- binder ensure a consistent view of any given type or object. If pragma
3602 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3603 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3605 -- Original_Access_Type (Node28)
3606 -- Defined in E_Access_Subprogram_Type entities. Set only if the access
3607 -- type was generated by the expander as part of processing an access
3608 -- to protected subprogram type. Points to the access to protected
3611 -- Original_Array_Type (Node21)
3612 -- Defined in modular types and array types and subtypes. Set only if
3613 -- the Is_Packed_Array_Impl_Type flag is set, indicating that the type
3614 -- is the implementation type for a packed array, and in this case it
3615 -- points to the original array type for which this is the packed
3616 -- array implementation type.
3618 -- Original_Record_Component (Node22)
3619 -- Defined in components, including discriminants. The usage depends
3620 -- on whether the record is a base type and whether it is tagged.
3622 -- In base tagged types:
3623 -- When the component is inherited in a record extension, it points
3624 -- to the original component (the entity of the ancestor component
3625 -- which is not itself inherited) otherwise it points to itself. The
3626 -- backend uses this attribute to implement the automatic dereference
3627 -- in the extension and to apply the transformation:
3629 -- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
3631 -- In base untagged types:
3632 -- Always points to itself except for non-girder discriminants, where
3633 -- it points to the girder discriminant it renames.
3635 -- In subtypes (tagged and untagged):
3636 -- Points to the component in the base type.
3638 -- Overlays_Constant (Flag243)
3639 -- Defined in all entities. Set only for a variable for which there is
3640 -- an address clause which causes the variable to overlay a constant.
3642 -- Overridden_Operation (Node26)
3643 -- Defined in subprograms. For overriding operations, points to the
3644 -- user-defined parent subprogram that is being overridden. Note: this
3645 -- attribute uses the same field as Static_Initialization. The latter
3646 -- is only defined for internal initialization procedures, for which
3647 -- Overridden_Operation is irrelevant. Thus this attribute must not be
3648 -- set for init_procs.
3650 -- Package_Instantiation (Node26)
3651 -- Defined in packages and generic packages. When defined, this field
3652 -- references an N_Generic_Instantiation node associated with an
3653 -- instantiated package. In the case where the referenced node has
3654 -- been rewritten to an N_Package_Specification, the instantiation
3655 -- node is available from the Original_Node field of the package spec
3656 -- node. This is currently not guaranteed to be set in all cases, but
3657 -- when set, the field is used in Get_Package_Instantiation_Node as
3658 -- one of the means of obtaining the instantiation node. Eventually
3659 -- it should be set in all cases, including package entities associated
3660 -- with formal packages. ???
3662 -- Packed_Array_Impl_Type (Node23)
3663 -- Defined in array types and subtypes, including the string literal
3664 -- subtype case, if the corresponding type is packed (either bit packed
3665 -- or packed to eliminate holes in non-contiguous enumeration type index
3666 -- types). References the type used to represent the packed array, which
3667 -- is either a modular type for short static arrays, or an array of
3668 -- System.Unsigned. Note that in some situations (internal types, and
3669 -- references to fields of variant records), it is not always possible
3670 -- to construct this type in advance of its use. If this field is empty,
3671 -- then the necessary type is declared on the fly for each reference to
3674 -- Parameter_Mode (synthesized)
3675 -- Applies to formal parameter entities. This is a synonym for Ekind,
3676 -- used when obtaining the formal kind of a formal parameter (the result
3677 -- is one of E_[In/Out/In_Out]_Parameter)
3679 -- Parent_Subtype (Node19) [base type only]
3680 -- Defined in E_Record_Type. Set only for derived tagged types, in which
3681 -- case it points to the subtype of the parent type. This is the type
3682 -- that is used as the Etype of the _parent field.
3684 -- Part_Of_Constituents (Elist9)
3685 -- Present in abstract state entities. Contains all constituents that are
3686 -- subject to indicator Part_Of (both aspect and option variants).
3688 -- Partial_View_Has_Unknown_Discr (Flag280)
3689 -- Present in all types. Set to Indicate that the partial view of a type
3690 -- has unknown discriminants. A default initialization of an object of
3691 -- the type does not require an invariant check (AI12-0133).
3693 -- Pending_Access_Types (Elist15)
3694 -- Defined in all types. Set for incomplete, private, Taft-amendment
3695 -- types, and their corresponding full views. This list contains all
3696 -- access types, both named and anonymous, declared between the partial
3697 -- and the full view. The list is used by the finalization machinery to
3698 -- ensure that the finalization masters of all pending access types are
3699 -- fully initialized when the full view is frozen.
3701 -- Postconditions_Proc (Node14)
3702 -- Defined in functions, procedures, entries, and entry families. Refers
3703 -- to the entity of the _Postconditions procedure used to check contract
3704 -- assertions on exit from a subprogram.
3706 -- PPC_Wrapper (Node25)
3707 -- Defined in entries and entry families. Set only if pre- or post-
3708 -- conditions are present. The precondition_wrapper body is the original
3709 -- entry call, decorated with the given precondition for the entry.
3711 -- Predicate_Function (synthesized)
3712 -- Defined in all types. Set for types for which (Has_Predicates is True)
3713 -- and for which a predicate procedure has been built that tests that the
3714 -- specified predicates are True. Contains the entity for the function
3715 -- which takes a single argument of the given type, and returns True if
3716 -- the predicate holds and False if it does not.
3718 -- Note: the reason this is marked as a synthesized attribute is that the
3719 -- way this is stored is as an element of the Subprograms_For_Type field.
3721 -- Predicate_Function_M (synthesized)
3722 -- Defined in all types. Present only if Predicate_Function is present,
3723 -- and only if the predicate function has Raise_Expression nodes. It
3724 -- is the special version created for membership tests, where if one of
3725 -- these raise expressions is executed, the result is to return False.
3727 -- Primitive_Operations (synthesized)
3728 -- Defined in concurrent types, tagged record types and subtypes, tagged
3729 -- private types and tagged incomplete types. For concurrent types whose
3730 -- Corresponding_Record_Type (CRT) is available, returns the list of
3731 -- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist.
3732 -- For all the other types returns the Direct_Primitive_Operations.
3735 -- Defined in private components of protected types. Refers to the entity
3736 -- of the component renaming declaration generated inside protected
3737 -- subprograms, entries or barrier functions.
3739 -- Prival_Link (Node20)
3740 -- Defined in constants and variables which rename private components of
3741 -- protected types. Set to the original private component.
3743 -- Private_Dependents (Elist18)
3744 -- Defined in private (sub)types. Records the subtypes of the private
3745 -- type, derivations from it, and records and arrays with components
3746 -- dependent on the type.
3748 -- The subtypes are traversed when installing and deinstalling (the full
3749 -- view of) a private type in order to ensure correct view of the
3752 -- Used in similar fashion for incomplete types: holds list of subtypes
3753 -- of these incomplete types that have discriminant constraints. The
3754 -- full views of these subtypes are constructed when the full view of
3755 -- the incomplete type is processed.
3757 -- In addition, if the incomplete type is the designated type in an
3758 -- access definition for an access parameter, the operation may be
3759 -- a dispatching primitive operation, which is only known when the full
3760 -- declaration of the type is seen. Subprograms that have such an
3761 -- access parameter are also placed in the list of private_dependents.
3763 -- Private_View (Node22)
3764 -- For each private type, three entities are allocated, the private view,
3765 -- the full view, and the shadow entity. The shadow entity contains a
3766 -- copy of the private view and is used for restoring the proper private
3767 -- view after a region in which the full view is visible (and is copied
3768 -- into the entity normally used for the private view during this period
3769 -- of visibility). The Private_View field is self-referential when the
3770 -- private view lives in its normal entity, but in the copy that is made
3771 -- in the shadow entity, it points to the proper location in which to
3772 -- restore the private view saved in the shadow.
3774 -- Protected_Formal (Node22)
3775 -- Defined in formal parameters (in, in out and out parameters). Used
3776 -- only for formals of protected operations. References corresponding
3777 -- formal parameter in the unprotected version of the operation that
3778 -- is created during expansion.
3780 -- Protected_Body_Subprogram (Node11)
3781 -- Defined in protected operations. References the entity for the
3782 -- subprogram which implements the body of the operation.
3784 -- Protection_Object (Node23)
3785 -- Applies to protected entries, entry families and subprograms. Denotes
3786 -- the entity which is used to rename the _object component of protected
3789 -- Reachable (Flag49)
3790 -- Defined in labels. The flag is set over the range of statements in
3791 -- which a goto to that label is legal.
3793 -- Referenced (Flag156)
3794 -- Defined in all entities. Set if the entity is referenced, except for
3795 -- the case of an appearance of a simple variable that is not a renaming
3796 -- as the left side of an assignment in which case Referenced_As_LHS is
3797 -- set instead, or a similar appearance as an out parameter actual, in
3798 -- which case Referenced_As_Out_Parameter is set.
3800 -- Referenced_As_LHS (Flag36):
3801 -- Defined in all entities. This flag is set instead of Referenced if a
3802 -- simple variable that is not a renaming appears as the left side of an
3803 -- assignment. The reason we distinguish this kind of reference is that
3804 -- we have a separate warning for variables that are only assigned and
3807 -- Referenced_As_Out_Parameter (Flag227):
3808 -- Defined in all entities. This flag is set instead of Referenced if a
3809 -- simple variable that is not a renaming appears as an actual for an out
3810 -- formal. The reason we distinguish this kind of reference is that
3811 -- we have a separate warning for variables that are only assigned and
3812 -- never read, and out parameters are a special case.
3814 -- Refinement_Constituents (Elist8)
3815 -- Present in abstract state entities. Contains all the constituents that
3816 -- refine the state, in other words, all the hidden states that appear in
3817 -- the constituent_list of aspect/pragma Refined_State.
3819 -- Register_Exception_Call (Node20)
3820 -- Defined in exception entities. When an exception is declared,
3821 -- a call is expanded to Register_Exception. This field points to
3822 -- the expanded N_Procedure_Call_Statement node for this call. It
3823 -- is used for Import/Export_Exception processing to modify the
3824 -- register call to make appropriate entries in the special tables
3825 -- used for handling these pragmas at runtime.
3827 -- Related_Array_Object (Node25)
3828 -- Defined in array types and subtypes. Used only for the base type
3829 -- and subtype created for an anonymous array object. Set to point
3830 -- to the entity of the corresponding array object. Currently used
3831 -- only for type-related error messages.
3833 -- Related_Expression (Node24)
3834 -- Defined in variables and types. When Set for internally generated
3835 -- entities, it may be used to denote the source expression whose
3836 -- elaboration created the variable declaration. If set, it is used
3837 -- for generating clearer messages from CodePeer. It is used on source
3838 -- entities that are variables in iterator specifications, to provide
3839 -- a link to the container that is the domain of iteration. This allows
3840 -- for better cross-reference information when the loop modifies elements
3841 -- of the container, and suppresses spurious warnings.
3843 -- Shouldn't it also be used for the same purpose in errout? It seems
3844 -- odd to have two mechanisms here???
3846 -- Related_Instance (Node15)
3847 -- Defined in the wrapper packages created for subprogram instances.
3848 -- The internal subprogram that implements the instance is inside the
3849 -- wrapper package, but for debugging purposes its external symbol
3850 -- must correspond to the name and scope of the related instance.
3852 -- Related_Type (Node27)
3853 -- Defined in components, constants and variables. Set when there is an
3854 -- associated dispatch table to point to entities containing primary or
3855 -- secondary tags. Not set in the _tag component of record types.
3857 -- Relative_Deadline_Variable (Node28) [implementation base type only]
3858 -- Defined in task type entities. This flag is set if a valid and
3859 -- effective pragma Relative_Deadline applies to the base type. Points
3860 -- to the entity for a variable that is created to hold the value given
3861 -- in a Relative_Deadline pragma for a task type.
3863 -- Renamed_Entity (Node18)
3864 -- Defined in exceptions, packages, subprograms, and generic units. Set
3865 -- for entities that are defined by a renaming declaration. Denotes the
3866 -- renamed entity, or transitively the ultimate renamed entity if
3867 -- there is a chain of renaming declarations. Empty if no renaming.
3869 -- Renamed_In_Spec (Flag231)
3870 -- Defined in package entities. If a package renaming occurs within
3871 -- a package spec, then this flag is set on the renamed package. The
3872 -- purpose is to prevent a warning about unused entities in the renamed
3873 -- package. Such a warning would be inappropriate since clients of the
3874 -- package can see the entities in the package via the renaming.
3876 -- Renamed_Object (Node18)
3877 -- Defined in all objects (constants, variables, components, formal
3878 -- parameters, generic formal parameters, and loop parameters).
3879 -- ??? Defined in discriminants?
3880 -- Set non-Empty if the object was declared by a renaming declaration,
3881 -- in which case it references the tree node for the name of the renamed
3882 -- object. This is only possible for the variable and constant cases.
3883 -- For formal parameters, this field is used in the course of inline
3884 -- expansion, to map the formals of a subprogram into the corresponding
3885 -- actuals. For formals of a task entry, it denotes the local renaming
3886 -- that replaces the actual within the accept statement. The field is
3887 -- Empty otherwise (it is always empty for loop parameters).
3889 -- Renaming_Map (Uint9)
3890 -- Defined in generic subprograms, generic packages, and their
3891 -- instances. Also defined in the instances of the corresponding
3892 -- bodies. Denotes the renaming map (generic entities => instance
3893 -- entities) used to construct the instance by givin an index into
3894 -- the tables used to represent these maps. See Sem_Ch12 for further
3895 -- details. The maps for package instances are also used when the
3896 -- instance is the actual corresponding to a formal package.
3898 -- Requires_Overriding (Flag213)
3899 -- Defined in all subprograms and entries. Set for subprograms that
3900 -- require overriding as defined by RM-2005-3.9.3(6/2). Note that this
3901 -- is True only for implicitly declare subprograms; it is not set on the
3902 -- parent type's subprogram. See also Is_Abstract_Subprogram.
3904 -- Return_Present (Flag54)
3905 -- Defined in function and generic function entities. Set if the
3906 -- function contains a return statement (used for error checking).
3907 -- This flag can also be set in procedure and generic procedure
3908 -- entities (for convenience in setting it), but is only tested
3909 -- for the function case.
3911 -- Return_Applies_To (Node8)
3912 -- Defined in E_Return_Statement. Points to the entity representing
3913 -- the construct to which the return statement applies, as defined in
3914 -- RM-6.5(4/2). Note that a (simple) return statement within an
3915 -- extended_return_statement applies to the extended_return_statement,
3916 -- even though it causes the whole function to return.
3918 -- Returns_By_Ref (Flag90)
3919 -- Defined in function entities. Set if the function returns the result
3920 -- by reference, either because its return type is a by-reference-type
3921 -- or because the function explicitly uses the secondary stack.
3923 -- Returns_Limited_View (Flag134)
3924 -- Defined in function entities. Set if the return type of the function
3925 -- at the point of definition is a limited view. Used to handle the late
3926 -- freezing of the function when it is called in the current semantic
3927 -- unit while it is still unfrozen.
3929 -- Reverse_Bit_Order (Flag164) [base type only]
3930 -- Defined in all record type entities. Set if entity has a Bit_Order
3931 -- aspect (set by an aspect clause or attribute definition clause) that
3932 -- has reversed the order of bits from the default value. When this flag
3933 -- is set, a component clause must specify a set of bits entirely within
3934 -- a single storage unit (Ada 95) or within a single machine scalar (see
3935 -- Ada 2005 AI-133), or must occupy an integral number of storage units.
3937 -- Reverse_Storage_Order (Flag93) [base type only]
3938 -- Defined in all record and array type entities. Set if entity has a
3939 -- Scalar_Storage_Order aspect (set by an aspect clause or attribute
3940 -- definition clause) that has reversed the order of storage elements
3941 -- from the default value. When this flag is set for a record type,
3942 -- the Bit_Order aspect must be set to the same value (either explicitly
3943 -- or as the target default value).
3946 -- Defined in all type and subtype entities. Contains the value of
3947 -- type'Size as defined in the RM. See also the Esize field and
3948 -- and the description on "Handling of Type'Size Values". A value
3949 -- of zero in this field for a non-discrete type means that
3950 -- the front end has not yet determined the size value. For the
3951 -- case of a discrete type, this field is always set by the front
3952 -- end and zero is a legitimate value for a type with one value.
3954 -- Root_Type (synthesized)
3955 -- Applies to all type entities. For class-wide types, returns the root
3956 -- type of the class covered by the CW type, otherwise returns the
3957 -- ultimate derivation ancestor of the given type. This function
3958 -- preserves the view, i.e. the Root_Type of a partial view is the
3959 -- partial view of the ultimate ancestor, the Root_Type of a full view
3960 -- is the full view of the ultimate ancestor. Note that this function
3961 -- does not correspond exactly to the use of root type in the RM, since
3962 -- in the RM root type applies to a class of types, not to a type.
3964 -- Scalar_Range (Node20)
3965 -- Defined in all scalar types (including modular types, where the
3966 -- bounds are 0 .. modulus - 1). References a node in the tree that
3967 -- contains the bounds for the range. Note that this information
3968 -- could be obtained by rummaging around the tree, but it is more
3969 -- convenient to have it immediately at hand in the entity. The
3970 -- contents of Scalar_Range can either be an N_Subtype_Indication
3971 -- node (with a constraint), or a Range node, but not a simple
3972 -- subtype reference (a subtype is converted into a range).
3974 -- Scale_Value (Uint16)
3975 -- Defined in decimal fixed-point types and subtypes. Contains the scale
3976 -- for the type (i.e. the value of type'Scale = the number of decimal
3977 -- digits after the decimal point).
3980 -- Defined in all entities. Points to the entity for the scope (block,
3981 -- loop, subprogram, package etc.) in which the entity is declared.
3982 -- Since this field is in the base part of the entity node, the access
3983 -- routines for this field are in Sinfo. Note that for a child unit,
3984 -- the Scope will be the parent package, and for a root library unit,
3985 -- the Scope will be Standard.
3987 -- Scope_Depth (synthesized)
3988 -- Applies to program units, blocks, concurrent types and entries, and
3989 -- also to record types, i.e. to any entity that can appear on the scope
3990 -- stack. Yields the scope depth value, which for those entities other
3991 -- than records is simply the scope depth value, for record entities, it
3992 -- is the Scope_Depth of the record scope.
3994 -- Scope_Depth_Value (Uint22)
3995 -- Defined in program units, blocks, concurrent types, and entries.
3996 -- Indicates the number of scopes that statically enclose the declaration
3997 -- of the unit or type. Library units have a depth of zero. Note that
3998 -- record types can act as scopes but do NOT have this field set (see
3999 -- Scope_Depth above)
4001 -- Scope_Depth_Set (synthesized)
4002 -- Applies to a special predicate function that returns a Boolean value
4003 -- indicating whether or not the Scope_Depth field has been set. It is
4004 -- needed, since returns an invalid value in this case.
4006 -- Sec_Stack_Needed_For_Return (Flag167)
4007 -- Defined in scope entities (blocks, functions, procedures, tasks,
4008 -- entries). Set to True when secondary stack is used to hold the
4009 -- returned value of a function and thus should not be released on
4012 -- Shadow_Entities (List14)
4013 -- Defined in package and generic package entities. Points to a list
4014 -- of entities that correspond to private types. For each private type
4015 -- a shadow entity is created that holds a copy of the private view.
4016 -- In regions of the program where the full views of these private
4017 -- entities are visible, the full view is copied into the entity that
4018 -- is normally used to hold the private view, but the shadow entity
4019 -- copy is unchanged. The shadow entities are then used to restore the
4020 -- original private views at the end of the region. This list is a
4021 -- standard format list (i.e. First (Shadow_Entities) is the first
4022 -- entry and subsequent entries are obtained using Next.
4024 -- Shared_Var_Procs_Instance (Node22)
4025 -- Defined in variables. Set non-Empty only if Is_Shared_Passive is
4026 -- set, in which case this is the entity for the associated instance of
4027 -- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details.
4029 -- Size_Check_Code (Node19)
4030 -- Defined in constants and variables. Normally Empty. Set if code is
4031 -- generated to check the size of the object. This field is used to
4032 -- suppress this code if a subsequent address clause is encountered.
4034 -- Size_Clause (synthesized)
4035 -- Applies to all entities. If a size clause is present in the rep
4036 -- item chain for an entity then the attribute definition clause node
4037 -- for the size clause is returned. Otherwise Size_Clause returns Empty
4038 -- if no item is present. Usually this is only meaningful if the flag
4039 -- Has_Size_Clause is set. This is because when the representation item
4040 -- chain is copied for a derived type, it can inherit a size clause that
4041 -- is not applicable to the entity.
4043 -- Size_Depends_On_Discriminant (Flag177)
4044 -- Defined in all entities for types and subtypes. Indicates that the
4045 -- size of the type depends on the value of one or more discriminants.
4046 -- Currently, this flag is only set for arrays which have one or more
4047 -- bounds depending on a discriminant value.
4049 -- Size_Known_At_Compile_Time (Flag92)
4050 -- Defined in all entities for types and subtypes. Indicates that the
4051 -- size of objects of the type is known at compile time. This flag is
4052 -- used to optimize some generated code sequences, and also to enable
4053 -- some error checks (e.g. disallowing component clauses on variable
4054 -- length objects). It is set conservatively (i.e. if it is True, the
4055 -- size is certainly known at compile time, if it is False, then the
4056 -- size may or may not be known at compile time, but the code will
4057 -- assume that it is not known). Note that the value may be known only
4058 -- to the back end, so the fact that this flag is set does not mean that
4059 -- the front end can access the value.
4061 -- Small_Value (Ureal21)
4062 -- Defined in fixed point types. Points to the universal real for the
4063 -- Small of the type, either as given in a representation clause, or
4064 -- as computed (as a power of two) by the compiler.
4066 -- SPARK_Aux_Pragma (Node33)
4067 -- Present in package spec and body entities. For a package spec entity
4068 -- it relates to the SPARK mode setting for the private part. This field
4069 -- points to the N_Pragma node that applies to the private part. This is
4070 -- either set with a local SPARK_Mode pragma in the private part or it is
4071 -- inherited from the SPARK mode that applies to the rest of the spec.
4072 -- For a package body, it similarly applies to the SPARK mode setting for
4073 -- the elaboration sequence after the BEGIN. In the case where the pragma
4074 -- is inherited, the SPARK_Aux_Pragma_Inherited flag is set in the
4075 -- package spec or body entity.
4077 -- SPARK_Aux_Pragma_Inherited (Flag266)
4078 -- Present in the entities of subprogram specs and bodies as well as
4079 -- in package specs and bodies. Set if the SPARK_Aux_Pragma field
4080 -- points to a pragma that is inherited, rather than a local one.
4082 -- SPARK_Pragma (Node32)
4083 -- Present in the entities of subprogram specs and bodies as well as in
4084 -- package specs and bodies. Points to the N_Pragma node that applies to
4085 -- the spec or body. This is either set by a local SPARK_Mode pragma or
4086 -- is inherited from the context (from an outer scope for the spec case
4087 -- or from the spec for the body case). In the case where it is inherited
4088 -- the flag SPARK_Pragma_Inherited is set. Empty if no SPARK_Mode pragma
4091 -- SPARK_Pragma_Inherited (Flag265)
4092 -- Present in the entities of subprogram specs and bodies as well as in
4093 -- package specs and bodies. Set if the SPARK_Pragma field points to a
4094 -- pragma that is inherited, rather than a local one.
4096 -- Spec_Entity (Node19)
4097 -- Defined in package body entities. Points to corresponding package
4098 -- spec entity. Also defined in subprogram body parameters in the
4099 -- case where there is a separate spec, where this field references
4100 -- the corresponding parameter entities in the spec.
4102 -- SSO_Set_High_By_Default (Flag273) [base type only]
4103 -- Defined for record and array types. Set in the base type if a pragma
4104 -- Default_Scalar_Storage_Order (High_Order_First) was active at the time
4105 -- the record or array was declared and therefore applies to it.
4107 -- SSO_Set_Low_By_Default (Flag272) [base type only]
4108 -- Defined for record and array types. Set in the base type if a pragma
4109 -- Default_Scalar_Storage_Order (High_Order_First) was active at the time
4110 -- the record or array was declared and therefore applies to it.
4112 -- Static_Discrete_Predicate (List25)
4113 -- Defined in discrete types/subtypes with static predicates (with the
4114 -- two flags Has_Predicates and Has_Static_Predicate set). Set if the
4115 -- type/subtype has a static predicate. Points to a list of expression
4116 -- and N_Range nodes that represent the predicate in canonical form. The
4117 -- canonical form has entries sorted in ascending order, with duplicates
4118 -- eliminated, and adjacent ranges coalesced, so that there is always a
4119 -- gap in the values between successive entries. The entries in this list
4120 -- are fully analyzed and typed with the base type of the subtype. Note
4121 -- that all entries are static and have values within the subtype range.
4123 -- Static_Real_Or_String_Predicate (Node25)
4124 -- Defined in real types/subtypes with static predicates (with the two
4125 -- flags Has_Predicates and Has_Static_Predicate set). Set if the type
4126 -- or subtype has a static predicate. Points to the return expression
4127 -- of the predicate function. This is the original expression given as
4128 -- the predicate except that occurrences of the type are replaced by
4129 -- occurrences of the formal parameter of the predicate function (note
4130 -- that the spec of this function including this formal parameter name)
4131 -- is available from the Subprograms_For_Type field (it can be accessed
4132 -- as Predicate_Function (typ). Also, in the case where a predicate is
4133 -- inherited, the expression is of the form:
4135 -- expression AND THEN xxxPredicate (typ2 (ent))
4137 -- where typ2 is the type from which the predicate is inherited, ent is
4138 -- the entity for the current predicate function, and xxxPredicate is the
4139 -- inherited predicate (from typ2). Finally for a predicate that inherits
4140 -- from another predicate but does not add a predicate of its own, the
4141 -- expression may consist of the above xxxPredicate call on its own.
4143 -- Status_Flag_Or_Transient_Decl (Node15)
4144 -- Defined in variables and constants. Applies to objects that require
4145 -- special treatment by the finalization machinery, such as extended
4146 -- return results, IF and CASE expression results, and objects inside
4147 -- N_Expression_With_Actions nodes. The attribute contains the entity
4148 -- of a flag which specifies particular behavior over a region of code
4149 -- or the declaration of a "hook" object.
4150 -- In which case is it a flag, or a hook object???
4152 -- Static_Elaboration_Desired (Flag77)
4153 -- Defined in library-level packages. Set by the pragma of the same
4154 -- name, to indicate that static initialization must be attempted for
4155 -- all types declared in the package, and that a warning must be emitted
4156 -- for those types to which static initialization is not available.
4158 -- Static_Initialization (Node30)
4159 -- Defined in initialization procedures for types whose objects can be
4160 -- initialized statically. The value of this attribute is a positional
4161 -- aggregate whose components are compile-time static values. Used
4162 -- when available in object declarations to eliminate the call to the
4163 -- initialization procedure, and to minimize elaboration code. Note:
4164 -- This attribute uses the same field as Overridden_Operation, which is
4165 -- irrelevant in init_procs.
4167 -- Storage_Size_Variable (Node26) [implementation base type only]
4168 -- Defined in access types and task type entities. This flag is set
4169 -- if a valid and effective pragma Storage_Size applies to the base
4170 -- type. Points to the entity for a variable that is created to
4171 -- hold the value given in a Storage_Size pragma for an access
4172 -- collection or a task type. Note that in the access type case,
4173 -- this field is defined only in the root type (since derived types
4174 -- share the same storage pool).
4176 -- Stored_Constraint (Elist23)
4177 -- Defined in entities that can have discriminants (concurrent types
4178 -- subtypes, record types and subtypes, private types and subtypes,
4179 -- limited private types and subtypes and incomplete types). Points
4180 -- to an element list containing the expressions for each of the
4181 -- stored discriminants for the record (sub)type.
4183 -- Stores_Attribute_Old_Prefix (Flag270)
4184 -- Defined in constants. Set when the constant has been generated to save
4185 -- the value of attribute 'Old's prefix.
4187 -- Strict_Alignment (Flag145) [implementation base type only]
4188 -- Defined in all type entities. Indicates that some containing part
4189 -- is either aliased or tagged. This prohibits packing the object
4190 -- tighter than its natural size and alignment.
4192 -- String_Literal_Length (Uint16)
4193 -- Defined in string literal subtypes (which are created to correspond
4194 -- to string literals in the program). Contains the length of the string
4197 -- String_Literal_Low_Bound (Node18)
4198 -- Defined in string literal subtypes (which are created to correspond
4199 -- to string literals in the program). Contains an expression whose
4200 -- value represents the low bound of the literal. This is a copy of
4201 -- the low bound of the applicable index constraint if there is one,
4202 -- or a copy of the low bound of the index base type if not.
4204 -- Subprograms_For_Type (Node29)
4205 -- Defined in all type and subprogram entities. This is used to hold
4206 -- a list of subprogram entities for subprograms associated with the
4207 -- type, linked through the Subprograms_For_Type field of the subprogram
4208 -- entity. Basically this is a way of multiplexing the single field to
4209 -- hold more than one entity (since we ran out of space in some type
4210 -- entities). This is currently used for Invariant_Procedure and also
4211 -- for Predicate_Function, and clients will always use the latter two
4212 -- names to access entries in this list.
4214 -- Subps_Index (Uint24)
4215 -- Present in subprogram entries. Set if the subprogram contains nested
4216 -- subprograms, or is a subprogram nested within such a subprogram. Holds
4217 -- the index in the Exp_Unst.Subps table for the subprogram. Note that
4218 -- for the outer level subprogram, this is the starting index in the Subp
4219 -- table for the entries for this subprogram.
4221 -- Suppress_Elaboration_Warnings (Flag148)
4222 -- Defined in all entities, can be set only for subprogram entities and
4223 -- for variables. If this flag is set then Sem_Elab will not generate
4224 -- elaboration warnings for the subprogram or variable. Suppression of
4225 -- such warnings is automatic for subprograms for which elaboration
4226 -- checks are suppressed (without the need to set this flag), but the
4227 -- flag is also set for various internal entities (such as init procs)
4228 -- which are known not to generate any possible access before
4229 -- elaboration, and it is set on variables when a warning is given to
4230 -- avoid multiple elaboration warnings for the same variable.
4232 -- Suppress_Initialization (Flag105)
4233 -- Defined in all variable, type and subtype entities. If set for a base
4234 -- type, then the generation of initialization procedures is suppressed
4235 -- for the type. Any other implicit initialiation (e.g. from the use of
4236 -- pragma Initialize_Scalars) is also suppressed if this flag is set for
4237 -- either the subtype in question, or for the base type. For variables,
4238 -- this flag suppresses all implicit initialization for the object, even
4239 -- if the type would normally require initialization. Set by use of
4240 -- pragma Suppress_Initialization and also for internal entities where
4241 -- we know that no initialization is required. For example, enumeration
4242 -- image table entities set it.
4244 -- Suppress_Style_Checks (Flag165)
4245 -- Defined in all entities. Suppresses any style checks specifically
4246 -- associated with the given entity if set.
4248 -- Suppress_Value_Tracking_On_Call (Flag217)
4249 -- Defined in all entities. Set in a scope entity if value tracking is to
4250 -- be suppressed on any call within the scope. Used when an access to a
4251 -- local subprogram is computed, to deal with the possibility that this
4252 -- value may be passed around, and if used, may clobber a local variable.
4254 -- Task_Body_Procedure (Node25)
4255 -- Defined in task types and subtypes. Points to the entity for the task
4256 -- task body procedure (as further described in Exp_Ch9, task bodies are
4257 -- expanded into procedures). A convenient function to retrieve this
4258 -- field is Sem_Util.Get_Task_Body_Procedure.
4260 -- The last sentence is odd??? Why not have Task_Body_Procedure go to the
4261 -- Underlying_Type of the Root_Type???
4263 -- Thunk_Entity (Node31)
4264 -- Defined in functions and procedures which have been classified as
4265 -- Is_Thunk. Set to the target entity called by the thunk.
4267 -- Treat_As_Volatile (Flag41)
4268 -- Defined in all type entities, and also in constants, components and
4269 -- variables. Set if this entity is to be treated as volatile for code
4270 -- generation purposes. Always set if Is_Volatile is set, but can also
4271 -- be set as a result of situations (such as address overlays) where
4272 -- the front end wishes to force volatile handling to inhibit aliasing
4273 -- optimization which might be legally ok, but is undesirable. Note
4274 -- that the backend always tests this flag rather than Is_Volatile.
4275 -- The front end tests Is_Volatile if it is concerned with legality
4276 -- checks associated with declared volatile variables, but if the test
4277 -- is for the purposes of suppressing optimizations, then the front
4278 -- end should test Treat_As_Volatile rather than Is_Volatile.
4280 -- Note: before testing Treat_As_Volatile, consider whether it would
4281 -- be more appropriate to use Exp_Util.Is_Volatile_Reference instead,
4282 -- which catches more cases of volatile references.
4284 -- Type_High_Bound (synthesized)
4285 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
4286 -- the high bound of a scalar type. The returned value is literal for a
4287 -- base type, but may be an expression in the case of scalar type with
4288 -- dynamic bounds. Note that in the case of a fixed point type, the high
4289 -- bound is in units of small, and is an integer.
4291 -- Type_Low_Bound (synthesized)
4292 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
4293 -- the low bound of a scalar type. The returned value is literal for a
4294 -- base type, but may be an expression in the case of scalar type with
4295 -- dynamic bounds. Note that in the case of a fixed point type, the low
4296 -- bound is in units of small, and is an integer.
4298 -- Underlying_Full_View (Node19)
4299 -- Defined in private subtypes that are the completion of other private
4300 -- types, or in private types that are derived from private subtypes. If
4301 -- the full view of a private type T is derived from another private type
4302 -- with discriminants Td, the full view of T is also private, and there
4303 -- is no way to attach to it a further full view that would convey the
4304 -- structure of T to the backend. The Underlying_Full_View is an
4305 -- attribute of the full view that is a subtype of Td with the same
4306 -- constraint as the declaration for T. The declaration for this subtype
4307 -- is built at the point of the declaration of T, either as completion,
4308 -- or as a subtype declaration where the base type is private and has a
4309 -- private completion. If Td is already constrained, then its full view
4310 -- can serve directly as the full view of T.
4312 -- Underlying_Record_View (Node28)
4313 -- Defined in record types. Set for record types that are extensions of
4314 -- types with unknown discriminants, and also set for internally built
4315 -- underlying record views to reference its original record type. Record
4316 -- types that are extensions of types with unknown discriminants do not
4317 -- have a completion, but they cannot be used without having some
4318 -- discriminated view at hand. This view is a record type with the same
4319 -- structure, whose parent type is the full view of the parent in the
4320 -- original type extension.
4322 -- Underlying_Type (synthesized)
4323 -- Applies to all entities. This is the identity function except in the
4324 -- case where it is applied to an incomplete or private type, in which
4325 -- case it is the underlying type of the type declared by the completion,
4326 -- or Empty if the completion has not yet been encountered and analyzed.
4328 -- Note: the reason this attribute applies to all entities, and not just
4329 -- types, is to legitimize code where Underlying_Type is applied to an
4330 -- entity which may or may not be a type, with the intent that if it is a
4331 -- type, its underlying type is taken.
4333 -- Note also that the value of this attribute is interesting only after
4334 -- the full view of the parent type has been processed. If the parent
4335 -- type is declared in an enclosing package, the attribute will be non-
4336 -- trivial only after the full view of the type has been analyzed.
4338 -- Universal_Aliasing (Flag216) [implementation base type only]
4339 -- Defined in all type entities. Set to direct the back-end to avoid
4340 -- any optimizations based on type-based alias analysis for this type.
4341 -- Indicates that objects of this type can alias objects of any other
4342 -- types, which guarantees that any objects can be referenced through
4343 -- access types designating this type safely, whatever the actual type
4344 -- of these objects. In other words, the effect is as though access
4345 -- types designating this type were subject to No_Strict_Aliasing.
4347 -- Unset_Reference (Node16)
4348 -- Defined in variables and out parameters. This is normally Empty. It
4349 -- is set to point to an identifier that represents a reference to the
4350 -- entity before any value has been set. Only the first such reference
4351 -- is identified. This field is used to generate a warning message if
4352 -- necessary (see Sem_Warn.Check_Unset_Reference).
4354 -- Used_As_Generic_Actual (Flag222)
4355 -- Defined in all entities, set if the entity is used as an argument to
4356 -- a generic instantiation. Used to tune certain warning messages.
4358 -- Uses_Lock_Free (Flag188)
4359 -- Defined in protected type entities. Set to True when the Lock Free
4360 -- implementation is used for the protected type. This implemenatation is
4361 -- based on atomic transactions and doesn't require anymore the use of
4362 -- Protection object (see System.Tasking.Protected_Objects).
4364 -- Uses_Sec_Stack (Flag95)
4365 -- Defined in scope entities (block, entry, function, loop, procedure,
4366 -- task). Set to True when secondary stack is used in this scope and must
4367 -- be released on exit unless Sec_Stack_Needed_For_Return is set.
4369 -- Warnings_Off (Flag96)
4370 -- Defined in all entities. Set if a pragma Warnings (Off, entity-name)
4371 -- is used to suppress warnings for a given entity. It is also used by
4372 -- the compiler in some situations to kill spurious warnings. Note that
4373 -- clients should generally not test this flag directly, but instead
4374 -- use function Has_Warnings_Off.
4376 -- Warnings_Off_Used (Flag236)
4377 -- Defined in all entities. Can only be set if Warnings_Off is set. If
4378 -- set indicates that a warning was suppressed by the Warnings_Off flag,
4379 -- and Unmodified/Unreferenced would not have suppressed the warning.
4381 -- Warnings_Off_Used_Unmodified (Flag237)
4382 -- Defined in all entities. Can only be set if Warnings_Off is set and
4383 -- Has_Pragma_Unmodified is not set. If set indicates that a warning was
4384 -- suppressed by the Warnings_Off status but that pragma Unmodified
4385 -- would also have suppressed the warning.
4387 -- Warnings_Off_Used_Unreferenced (Flag238)
4388 -- Defined in all entities. Can only be set if Warnings_Off is set and
4389 -- Has_Pragma_Unreferenced is not set. If set indicates that a warning
4390 -- was suppressed by the Warnings_Off status but that pragma Unreferenced
4391 -- would also have suppressed the warning.
4393 -- Was_Hidden (Flag196)
4394 -- Defined in all entities. Used to save the value of the Is_Hidden
4395 -- attribute when the limited-view is installed (Ada 2005: AI-217).
4397 -- Wrapped_Entity (Node27)
4398 -- Defined in functions and procedures which have been classified as
4399 -- Is_Primitive_Wrapper. Set to the entity being wrapper.
4401 ---------------------------
4402 -- Renaming and Aliasing --
4403 ---------------------------
4405 -- Several entity attributes relate to renaming constructs, and to the use of
4406 -- different names to refer to the same entity. The following is a summary of
4407 -- these constructs and their prefered uses.
4409 -- There are three related attributes:
4415 -- They all overlap because they are supposed to apply to different entity
4416 -- kinds. They are semantically related, and have the following intended uses:
4418 -- a) Renamed_Entity appplies to entities in renaming declarations that rename
4419 -- an entity, so the value of the attribute IS an entity. This applies to
4420 -- generic renamings, package renamings, exception renamings, and subprograms
4421 -- renamings that rename a subprogram (rather than an attribute, an entry, a
4422 -- protected operation, etc).
4424 -- b) Alias applies to overloadable entities, and the value is an overloadable
4425 -- entity. so this is a subset of the previous one. We use the term Alias to
4426 -- cover both renamings and inherited operations, because both cases are
4427 -- handled in the same way when expanding a call. namely the Alias of a given
4428 -- subprogram is the subprogram that will actually be called.
4430 -- Both a) and b) are set transitively, so that in fact it is not necessary to
4431 -- traverse chains of renamings when looking for the original entity: it's
4432 -- there in one step (this is done when analyzing renaming declarations other
4433 -- than object renamings in sem_ch8).
4435 -- c) Renamed_Object applies to constants and variables. Given that the name
4436 -- in an object renaming declaration is not necessarily an entity name, the
4437 -- value of the attribute is the tree for that name, eg AR (1).Comp. The case
4438 -- when that name is in fact an entity is not handled specially. This is why
4439 -- in a few cases we need to use a loop to trace a chain of object renamings
4440 -- where all of them happen to be entities. So:
4443 -- Y : integer renames X; -- renamed object is the identifier X
4444 -- Z : integer renames Y; -- renamed object is the identifier Y
4446 -- The front-end does not store explicitly the fact that Z renames X.
4448 --------------------------------------
4449 -- Delayed Freezing and Elaboration --
4450 --------------------------------------
4452 -- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
4453 -- freeze node, which appears later in the expanded tree.
4455 -- a) The flag is used by the front-end to trigger expansion actions
4456 -- which include the generation of that freeze node. Typically this happens at
4457 -- the end of the current compilation unit, or before the first subprogram
4458 -- body is encountered in the current unit. See files freeze and exp_ch13 for
4459 -- details on the actions triggered by a freeze node, which include the
4460 -- construction of initialization procedures and dispatch tables.
4462 -- b) The flag is used by the backend to defer elaboration of the entity until
4463 -- its freeze node is seen. In the absence of an explicit freeze node, an
4464 -- entity is frozen (and elaborated) at the point of declaration.
4466 -- For object declarations, the flag is set when an address clause for the
4467 -- object is encountered. Legality checks on the address expression only
4468 -- take place at the freeze point of the object.
4470 -- Most types have an explicit freeze node, because they cannot be elaborated
4471 -- until all representation and operational items that apply to them have been
4472 -- analyzed. Private types and incomplete types have the flag set as well, as
4473 -- do task and protected types.
4475 -- Implicit base types created for type derivations, as well as classwide
4476 -- types created for all tagged types, have the flag set.
4478 -- If a subprogram has an access parameter whose designated type is incomplete
4479 -- the subprogram has the flag set.
4485 -- The following entity kinds are introduced by the corresponding type
4489 -- E_General_Access_Type,
4490 -- E_Access_Subprogram_Type,
4491 -- E_Anonymous_Access_Subprogram_Type,
4492 -- E_Access_Protected_Subprogram_Type,
4493 -- E_Anonymous_Access_Protected_Subprogram_Type
4494 -- E_Anonymous_Access_Type.
4496 -- E_Access_Subtype is for an access subtype created by a subtype
4499 -- In addition, we define the kind E_Allocator_Type to label allocators.
4500 -- This is because special resolution rules apply to this construct.
4501 -- Eventually the constructs are labeled with the access type imposed by
4502 -- the context. The backend should never see types with this Ekind.
4504 -- Similarly, the type E_Access_Attribute_Type is used as the initial kind
4505 -- associated with an access attribute. After resolution a specific access
4506 -- type will be established as determined by the context.
4508 -- Finally, the type Any_Access is used to label -null- during type
4509 -- resolution. Any_Access is also replaced by the context type after
4512 --------------------------------
4513 -- Classification of Entities --
4514 --------------------------------
4516 -- The classification of program entities which follows is a refinement of
4517 -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
4518 -- different type classes. Ada 95 entities include class wide types,
4519 -- protected types, subprogram types, generalized access types, generic
4520 -- formal derived types and generic formal packages.
4522 -- The order chosen for these kinds allows us to classify related entities
4523 -- so that they are contiguous. As a result, they do not appear in the
4524 -- exact same order as their order of first appearance in the LRM (For
4525 -- example, private types are listed before packages). The contiguity
4526 -- allows us to define useful subtypes (see below) such as type entities,
4527 -- overloaded entities, etc.
4529 -- Each entity (explicitly or implicitly declared) has a kind, which is
4530 -- a value of the following type:
4532 type Entity_Kind is (
4535 -- The initial Ekind value for a newly created entity. Also used as the
4536 -- Ekind for Standard_Void_Type, a type entity in Standard used as a
4537 -- dummy type for the return type of a procedure (the reason we create
4538 -- this type is to share the circuits for performing overload resolution
4546 -- Components of a record declaration, private declarations of
4547 -- protected objects.
4550 -- Constants created by an object declaration with a constant keyword

4914 -- A task body. This entity serves almost no function, since all
4915 -- semantic analysis uses the protected entity (E_Task_Type).
4918 -- A subprogram body. Used when a subprogram has a separate declaration
4919 -- to represent the entity for the body. This entity serves almost no

6442 -- Since E_Void is the initial Ekind value of an entity when it is first

6447 -- well controlled, and needs cleaning up later. Meanwhile, the access
6448 -- procedures in the body of Einfo permit many, but not all, attributes
6449 -- to be applied to an E_Void entity, precisely so that this kind of
6450 -- pre-setting of attributes works. This is really a hole in the dynamic
6451 -- type checking, since there is no assurance that the eventual Ekind

6457 -- Component_Alignment Control --

6460 -- There are four types of alignment possible for array and record

6462 -- following type indicating which alignment choice applies. For full
6463 -- details of the meaning of these alignment types, see description
6464 -- of the Component_Alignment pragma
6466 type Component_Alignment_Kind is (
6467 Calign_Default, -- default alignment
6468 Calign_Component_Size, -- natural alignment for component size
6469 Calign_Component_Size_4, -- natural for size <= 4, 4 for size >= 4
6470 Calign_Storage_Unit); -- all components byte aligned
6472 -----------------------------------
6473 -- Floating Point Representation --
6474 -----------------------------------
6476 type Float_Rep_Kind is (
6477 IEEE_Binary, -- IEEE 754p conforming binary format

6484 -- In addition to attributes that are stored as plain data, other
6485 -- attributes are procedural, and require some small amount of
6486 -- computation. Of course, from the point of view of a user of this
6487 -- package, the distinction is not visible (even the field information
6488 -- provided below should be disregarded, as it is subject to change
6489 -- without notice). A number of attributes appear as lists: lists of
6490 -- formals, lists of actuals, of discriminants, etc. For these, pairs
6491 -- of functions are defined, which take the form:
6493 -- function First_Thing (E : Enclosing_Construct) return Thing;
6494 -- function Next_Thing (T : Thing) return Thing;
6496 -- The end of iteration is always signaled by a value of Empty, so that
6497 -- loops over these chains invariably have the form:
6501 -- This := First_Thing (E);
6503 -- while Present (This) loop

6506 -- This := Next_Thing (This);

6510 -- Handling of Check Suppression --
6511 -----------------------------------
6513 -- There are three ways that checks can be suppressed:
6515 -- 1. At the command line level
6516 -- 2. At the scope level.
6517 -- 3. At the entity level.
6519 -- See spec of Sem in sem.ads for details of the data structures used
6520 -- to keep track of these various methods for suppressing checks.
6522 -------------------------------
6523 -- Handling of Discriminants --
6524 -------------------------------
6526 -- During semantic processing, discriminants are separate entities which
6527 -- reflect the semantic properties and allowed usage of discriminants in
6530 -- In the case of discriminants used as bounds, the references are handled
6531 -- directly, since special processing is needed in any case. However, there
6532 -- are two circumstances in which discriminants are referenced in a quite
6533 -- general manner, like any other variables:
6535 -- In initialization expressions for records. Note that the expressions
6536 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline
6537 -- pragmas are effectively in this category, since these pragmas are
6538 -- converted to initialized record fields in the Corresponding_Record_
6541 -- In task and protected bodies, where the discriminant values may be
6542 -- referenced freely within these bodies. Discriminants can also appear
6543 -- in bounds of entry families and in defaults of operations.
6545 -- In both these cases, the discriminants must be treated essentially as
6546 -- objects. The following approach is used to simplify and minimize the
6547 -- special processing that is required.
6549 -- When a record type with discriminants is analyzed, semantic processing
6550 -- creates the entities for the discriminants. It also creates additional
6551 -- sets of entities called discriminals, one for each of the discriminants,
6552 -- and the Discriminal field of the discriminant entity points to this
6553 -- additional entity, which is initially created as an uninitialized
6556 -- During expansion of expressions, any discriminant reference is replaced
6557 -- by a reference to the corresponding discriminal. When the initialization
6558 -- procedure for the record is created (there will always be one, since
6559 -- discriminants are present, see Exp_Ch3 for further details), the
6560 -- discriminals are used as the entities for the formal parameters of
6561 -- this initialization procedure. The references to these discriminants
6562 -- have already been replaced by references to these discriminals, which
6563 -- are now the formal parameters corresponding to the required objects.
6565 -- In the case of a task or protected body, the semantics similarly creates
6566 -- a set of discriminals for the discriminants of the task or protected
6567 -- type. When the procedure is created for the task body, the parameter
6568 -- passed in is a reference to the task value type, which contains the
6569 -- required discriminant values. The expander creates a set of declarations
6572 -- discr_nameD : constant discr_type renames _task.discr_name;
6574 -- where discr_nameD is the discriminal entity referenced by the task
6575 -- discriminant, and _task is the task value passed in as the parameter.
6576 -- Again, any references to discriminants in the task body have been
6577 -- replaced by the discriminal reference, which is now an object that
6578 -- contains the required value.
6580 -- This approach for tasks means that two sets of discriminals are needed
6581 -- for a task type, one for the initialization procedure, and one for the
6582 -- task body. This works out nicely, since the semantics allocates one set
6583 -- for the task itself, and one set for the corresponding record.
6585 -- The one bit of trickiness arises in making sure that the right set of
6586 -- discriminals is used at the right time. First the task definition is
6587 -- processed. Any references to discriminants here are replaced by the
6588 -- corresponding *task* discriminals (the record type doesn't even exist
6589 -- yet, since it is constructed as part of the expansion of the task
6590 -- declaration, which happens after the semantic processing of the task
6591 -- definition). The discriminants to be used for the corresponding record
6592 -- are created at the same time as the other discriminals, and held in the
6593 -- CR_Discriminant field of the discriminant. A use of the discriminant in
6594 -- a bound for an entry family is replaced with the CR_Discriminant because
6595 -- it controls the bound of the entry queue array which is a component of
6596 -- the corresponding record.
6598 -- Just before the record initialization routine is constructed, the
6599 -- expander exchanges the task and record discriminals. This has two
6600 -- effects. First the generation of the record initialization routine
6601 -- uses the discriminals that are now on the record, which is the set
6602 -- that used to be on the task, which is what we want.
6604 -- Second, a new set of (so far unused) discriminals is now on the task
6605 -- discriminants, and it is this set that will be used for expanding the
6606 -- task body, and also for the discriminal declarations at the start of
6609 ---------------------------------------------------
6610 -- Handling of private data in protected objects --
6611 ---------------------------------------------------
6613 -- Private components in protected types pose problems similar to those
6614 -- of discriminants. Private data is visible and can be directly referenced
6615 -- from protected bodies. However, when protected entries and subprograms
6616 -- are expanded into corresponding bodies and barrier functions, private
6617 -- components lose their original context and visibility.
6619 -- To remedy this side effect of expansion, private components are expanded
6620 -- into renamings called "privals", by analogy with "discriminals".
6622 -- private_comp : comp_type renames _object.private_comp;
6624 -- Prival declarations are inserted during the analysis of subprogram and
6625 -- entry bodies to ensure proper visibility for any subsequent expansion.
6626 -- _Object is the formal parameter of the generated corresponding body or
6627 -- a local renaming which denotes the protected object obtained from entry
6628 -- parameter _O. Privals receive minimal decoration upon creation and are
6629 -- categorized as either E_Variable for the general case or E_Constant when
6630 -- they appear in functions.
6632 -- Along with the local declarations, each private component carries a
6633 -- placeholder which references the prival entity in the current body. This
6634 -- form of indirection is used to resolve name clashes of privals and other
6635 -- locally visible entities such as parameters, local objects, entry family
6636 -- indexes or identifiers used in the barrier condition.
6638 -- When analyzing the statements of a protected subprogram or entry, any
6639 -- reference to a private component must resolve to the locally declared
6640 -- prival through normal visibility. In case of name conflicts (the cases
6641 -- above), the prival is marked as hidden and acts as a weakly declared
6642 -- entity. As a result, the reference points to the correct entity. When a
6643 -- private component is denoted by an expanded name (prot_type.comp for
6644 -- example), the expansion mechanism uses the placeholder of the component
6645 -- to correct the Entity and Etype of the reference.
6651 -- The following type synonyms are used to tidy up the function and
6652 -- procedure declarations that follow, and also to make it possible to meet
6653 -- the requirement for the XEINFO utility that all function specs must fit
6654 -- on a single source line.

7271 -- value has been set, then Known is True, and Unknown is False. If no
7272 -- value is set, then Known is False and Unknown is True. The Known_Static
7273 -- predicate is true only if the value is set (Known) and is set to a
7274 -- compile time known value. Note that in the case of Alignment and
7275 -- Normalized_First_Bit, dynamic values are not possible, so we do not
7276 -- need a separate Known_Static calls in these cases. The not set (unknown)
7277 -- values are as follows:
7279 -- Alignment Uint_0 or No_Uint
7280 -- Component_Size Uint_0 or No_Uint
7281 -- Component_Bit_Offset No_Uint
7282 -- Digits_Value Uint_0 or No_Uint
7283 -- Esize Uint_0 or No_Uint
7284 -- Normalized_First_Bit No_Uint
7285 -- Normalized_Position No_Uint
7286 -- Normalized_Position_Max No_Uint
7287 -- RM_Size Uint_0 or No_Uint
7289 -- It would be cleaner to use No_Uint in all these cases, but historically
7290 -- we chose to use Uint_0 at first, and the change over will take time ???
7291 -- This is particularly true for the RM_Size field, where a value of zero
7292 -- is legitimate. We deal with this by a considering that the value is
7293 -- always known static for discrete types (and no other types can have
7294 -- an RM_Size value of zero).
7296 -- In two cases, Known_Static_Esize and Known_Static_RM_Size, there is one
7297 -- more consideration, which is that we always return False for generic
7298 -- types. Within a template, the size can look known, because of the fake
7299 -- size values we put in template types, but they are not really known and
7300 -- anyone testing if they are known within the template should get False as
7301 -- a result to prevent incorrect assumptions.
