40 -- This package defines the annotations to the abstract syntax tree that
41 -- are needed to support semantic processing of an Ada compilation.
43 -- Note that after editing this spec and the corresponding body it is
44 -- required to run ceinfo to check the consistentcy of spec and body.
45 -- See ceinfo.adb for more information about the checks made.
47 -- These annotations are for the most part attributes of declared entities,
48 -- and they correspond to conventional symbol table information. Other
49 -- attributes include sets of meanings for overloaded names, possible
50 -- types for overloaded expressions, flags to indicate deferred constants,
51 -- incomplete types, etc. These attributes are stored in available fields
52 -- in tree nodes (i.e. fields not used by the parser, as defined by the
53 -- Sinfo package specification), and accessed by means of a set of
54 -- subprograms which define an abstract interface.
56 -- There are two kinds of semantic information
58 -- First, the tree nodes with the following Nkind values:
60 -- N_Defining_Identifier
61 -- N_Defining_Character_Literal
62 -- N_Defining_Operator_Symbol
64 -- are called Entities, and constitute the information that would often
65 -- be stored separately in a symbol table. These nodes are all extended
66 -- to provide extra space, and contain fields which depend on the entity
67 -- kind, as defined by the contents of the Ekind field. The use of the
68 -- Ekind field, and the associated fields in the entity, are defined
69 -- in this package, as are the access functions to these fields.
71 -- Second, in some cases semantic information is stored directly in other
72 -- kinds of nodes, e.g. the Etype field, used to indicate the type of an
73 -- expression. The access functions to these fields are defined in the
74 -- Sinfo package, but their full documentation is to be found in
75 -- the Einfo package specification.
77 -- Declaration processing places information in the nodes of their defining
78 -- identifiers. Name resolution places in all other occurrences of an
79 -- identifier a pointer to the corresponding defining occurrence.
81 --------------------------------
82 -- The XEINFO Utility Program --
83 --------------------------------
85 -- XEINFO is a utility program which automatically produces a C header file,
86 -- einfo.h from the spec and body of package Einfo. It reads the input
87 -- files einfo.ads and einfo.adb and produces the output file einfo.h.
88 -- XEINFO is run automatically by the build scripts when you do a full
91 -- In order for this utility program to operate correctly, the form of the
92 -- einfo.ads and einfo.adb files must meet certain requirements and be laid
93 -- out in a specific manner.
95 -- The general form of einfo.ads is as follows:
97 -- type declaration for type Entity_Kind
98 -- subtype declarations declaring subranges of Entity_Kind
99 -- subtype declarations declaring synonyms for some standard types
100 -- function specs for attributes
102 -- pragma Inline declarations
104 -- This order must be observed. There are no restrictions on the procedures,
105 -- since the C header file only includes functions (Gigi is not allowed to
106 -- modify the generated tree). However, functions are required to have headers
107 -- that fit on a single line.
109 -- XEINFO reads and processes the function specs and the pragma Inlines. For
110 -- functions that are declared as inlined, XEINFO reads the corresponding body
111 -- from einfo.adb, and processes it into C code. This results in some strict
112 -- restrictions on which functions can be inlined:
114 -- The function spec must be on a single line
116 -- There can only be a single statement, contained on a single line,
117 -- not counting any pragma Assert statements.
119 -- This single statement must either be a function call with simple,
120 -- single token arguments, or it must be a membership test of the form
121 -- a in b, where a and b are single tokens.
123 -- For functions that are not inlined, there is no restriction on the body,
124 -- and XEINFO generates a direct reference in the C header file which allows
125 -- the C code in Gigi to directly call the corresponding Ada body.
127 ----------------------------------
128 -- Handling of Type'Size Values --
129 ----------------------------------
131 -- The Ada 95 RM contains some rather peculiar (to us!) rules on the value
132 -- of type'Size (see RM 13.3(55)). We have found that attempting to use
133 -- these RM Size values generally, and in particular for determining the
134 -- default size of objects, creates chaos, and major incompatibilities in
137 -- We proceed as follows, for discrete and fixed-point subtypes, we have
138 -- two separate sizes for each subtype:
140 -- The Object_Size, which is used for determining the default size of
141 -- objects and components. This size value can be referred to using the
142 -- Object_Size attribute. The phrase "is used" here means that it is
143 -- the basis of the determination of the size. The backend is free to
144 -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
145 -- character might be stored in 32 bits on a machine with no efficient
146 -- byte access instructions such as the Alpha.
148 -- The default rules for the value of Object_Size for fixed-point and
149 -- discrete types are as follows:
151 -- The Object_Size for base subtypes reflect the natural hardware
152 -- size in bits (see Ttypes and Cstand for integer types). For
153 -- enumeration and fixed-point base subtypes have 8. 16. 32 or 64
154 -- bits for this size, depending on the range of values to be stored.
156 -- The Object_Size of a subtype is the same as the Object_Size of
157 -- the subtype from which it is obtained.
159 -- The Object_Size of a derived base type is copied from the parent
160 -- base type, and the Object_Size of a derived first subtype is copied
161 -- from the parent first subtype.
163 -- The Value_Size which is the number of bits required to store a value
164 -- of the type. This size can be referred to using the Value_Size
165 -- attribute. This value is used to determine how tightly to pack
166 -- records or arrays with components of this type, and also affects
167 -- the semantics of unchecked conversion (unchecked conversions where
168 -- the Value_Size values differ generate a warning, and are potentially
169 -- target dependent).
171 -- The default rule for the value of Value_Size are as follows:
173 -- The Value_Size for a base subtype is the minimum number of bits
174 -- required to store all values of the type (including the sign bit
175 -- only if negative values are possible).
177 -- If a subtype statically matches the first subtype, then it has
178 -- by default the same Value_Size as the first subtype. This is a
179 -- consequence of RM 13.1(14) ("if two subtypes statically match,
180 -- then their subtype-specific aspects are the same".)
182 -- All other subtypes have a Value_Size corresponding to the minimum
183 -- number of bits required to store all values of the subtype. For
184 -- dynamic bounds, it is assumed that the value can range down or up
185 -- to the corresponding bound of the ancestor
187 -- The RM defined attribute Size corresponds to the Value_Size attribute
189 -- The Size attribute may be defined for a first-named subtype. This sets
190 -- the Value_Size of the first-named subtype to the given value, and the
191 -- Object_Size of this first-named subtype to the given value padded up
192 -- to an appropriate boundary. It is a consequence of the default rules
193 -- above that this Object_Size will apply to all further subtypes. On the
194 -- other hand, Value_Size is affected only for the first subtype, any
195 -- dynamic subtypes obtained from it directly, and any statically matching
196 -- subtypes. The Value_Size of any other static subtypes is not affected.
198 -- Value_Size and Object_Size may be explicitly set for any subtype using
199 -- an attribute definition clause. Note that the use of these attributes
200 -- can cause the RM 13.1(14) rule to be violated. If two access types
201 -- reference aliased objects whose subtypes have differing Object_Size
202 -- values as a result of explicit attribute definition clauses, then it
203 -- is erroneous to convert from one access subtype to the other.
205 -- At the implementation level, Esize stores the Object_Size and the
206 -- RM_Size field stores the Value_Size (and hence the value of the
207 -- Size attribute, which, as noted above, is equivalent to Value_Size).
209 -- To get a feel for the difference, consider the following examples (note
210 -- that in each case the base is short_short_integer with a size of 8):
212 -- Object_Size Value_Size
214 -- type x1 is range 0..5; 8 3
216 -- type x2 is range 0..5;
217 -- for x2'size use 12; 16 12
219 -- subtype x3 is x2 range 0 .. 3; 16 2
221 -- subtype x4 is x2'base range 0 .. 10; 8 4
223 -- subtype x5 is x2 range 0 .. dynamic; 16 (7)
225 -- subtype x6 is x2'base range 0 .. dynamic; 8 (7)
227 -- Note: the entries marked (7) 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
307 -- the same physical field is used for different purposes in different
308 -- entities, so these access functions should only be referenced for the
309 -- class of entities in which they are defined as being present. Flags are
310 -- not 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 body),
312 -- 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 -- Accept_Address (Elist21)
332 -- Present in entries. If an accept has a statement sequence, then an
333 -- address variable is created, which is used to hold the address of the
334 -- parameters, as passed by the runtime. Accept_Address holds an element
335 -- list which represents a stack of entities for these address variables.
336 -- The current entry is the top of the stack, which is the last element
337 -- on the list. A stack is required to handle the case of nested select
338 -- statements referencing the same entry.
340 -- Access_Disp_Table (Elist16) [implementation base type only]
341 -- Present in E_Record_Type and E_Record_Subtype entities. Set in tagged
342 -- types to point to their dispatch tables. The first two entities are
343 -- associated with the primary dispatch table: 1) primary dispatch table
344 -- with user-defined primitives 2) primary dispatch table with predefined
345 -- primitives. For each interface type covered by the tagged type we also
346 -- have: 3) secondary dispatch table with thunks of primitives covering
347 -- user-defined interface primitives, 4) secondary dispatch table with
348 -- thunks of predefined primitives, 5) secondary dispatch table with user
349 -- defined primitives, and 6) secondary dispatch table with predefined
350 -- primitives. The last entity of this list is an access type declaration
351 -- used to expand dispatching calls through the primary dispatch table.
352 -- For a non-tagged record, contains No_Elist.
354 -- Actual_Subtype (Node17)
355 -- Present in variables, constants, and formal parameters. This is the
356 -- subtype imposed by the value of the object, as opposed to its nominal
357 -- subtype, which is imposed by the declaration. The actual subtype
358 -- differs from the nominal one when the latter is indefinite (as in the
359 -- case of an unconstrained formal parameter, or a variable declared
360 -- with an unconstrained type and an initial value). The nominal subtype
361 -- is the Etype entry for the entity. The Actual_Subtype field is set
362 -- only if the actual subtype differs from the nominal subtype. If the
363 -- actual and nominal subtypes are the same, then the Actual_Subtype
364 -- field is Empty, and Etype indicates both types.
366 -- For objects, the Actual_Subtype is set only if this is a discriminated
367 -- type. For arrays, the bounds of the expression are obtained and the
368 -- Etype of the object is directly the constrained subtype. This is
369 -- rather irregular, and the semantic checks that depend on the nominal
370 -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
372 -- Address_Clause (synthesized)
373 -- Applies to entries, objects and subprograms. Set if an address clause
374 -- is present which references the object or subprogram and points to
375 -- the N_Attribute_Definition_Clause node. Empty if no Address clause.
376 -- The expression in the address clause is always a constant that is
377 -- defined before the entity to which the address clause applies.
378 -- Note: Gigi references this field in E_Task_Type entities???
380 -- Address_Taken (Flag104)
381 -- Present in all entities. Set if the Address or Unrestricted_Access
382 -- attribute is applied directly to the entity, i.e. the entity is the
383 -- entity of the prefix of the attribute reference. Also set if the
384 -- entity is the second argument of an Asm_Input or Asm_Output attribute,
385 -- as the construct may entail taking its address. Used by Gigi to make
386 -- sure that the address can be meaningfully taken, and also in the case
387 -- of subprograms to control output of certain warnings.
389 -- Aft_Value (synthesized)
390 -- Applies to fixed and decimal types. Computes a universal integer
391 -- that holds value of the Aft attribute for the type.
394 -- Present in overloadable entities (literals, subprograms, entries) and
395 -- subprograms that cover a primitive operation of an abstract interface
396 -- (that is, subprograms with the Interface_Alias attribute). In case of
397 -- overloaded entities it points to the parent subprogram of a derived
398 -- subprogram. In case of abstract interface subprograms it points to the
399 -- subprogram that covers the abstract interface primitive. Also used for
400 -- a subprogram renaming, where it points to the renamed subprogram. For
401 -- an inherited operation (of a type extension) that is overridden in a
402 -- private part, the Alias is the overriding operation. In this fashion a
403 -- call from outside the package ends up executing the new body even if
404 -- non-dispatching, and a call from inside calls the overriding operation
405 -- because it hides the implicit one. Alias is always empty for entries.
407 -- Alignment (Uint14)
408 -- Present in entities for types and also in constants, variables
409 -- (including exceptions where it refers to the static data allocated for
410 -- an exception), loop parameters, and formal parameters. This indicates
411 -- the desired alignment for a type, or the actual alignment for an
412 -- object. A value of zero (Uint_0) indicates that the alignment has not
413 -- been set yet. The alignment can be set by an explicit alignment
414 -- clause, or set by the front-end in package Layout, or set by the
415 -- back-end as part of the back end back-annotation process. The
416 -- alignment field is also present in E_Exception entities, but there it
417 -- is used only by the back-end for back annotation.
419 -- Alignment_Clause (synthesized)
420 -- Applies to all entities for types and objects. If an alignment
421 -- attribute definition clause is present for the entity, then this
422 -- function returns the N_Attribute_Definition clause that specifies the
423 -- alignment. If no alignment clause applies to the type, then the call
424 -- to this function returns Empty. Note that the call can return a
425 -- non-Empty value even if Has_Alignment_Clause is not set (happens with
426 -- subtype and derived type declarations). Note also that a record
427 -- definition clause with an (obsolescent) mod clause is converted
428 -- into an attribute definition clause for this purpose.
430 -- Associated_Formal_Package (Node12)
431 -- Present in packages that are the actuals of formal_packages. Points
432 -- to the entity in the declaration for the formal package.
434 -- Associated_Node_For_Itype (Node8)
435 -- Present in all type and subtype entities. Set non-Empty only for
436 -- Itypes. Set to point to the associated node for the Itype, i.e.
437 -- the node whose elaboration generated the Itype. This is used for
438 -- copying trees, to determine whether or not to copy an Itype, and
439 -- also for accessibility checks on anonymous access types. This
440 -- node is typically an object declaration, component declaration,
441 -- type or subtype declaration. For an access discriminant in a type
442 -- declaration, the associated_node_for_itype is the discriminant
443 -- specification. For an access parameter it is the enclosing subprogram
446 -- Itypes have no explicit declaration, and therefore are not attached to
447 -- the tree: their Parent field is always empty. The Associated_Node_For_
448 -- Itype is the only way to determine the construct that leads to the
449 -- creation of a given itype entity.
451 -- Associated_Storage_Pool (Node22) [root type only]
452 -- Present in simple and general access type entities. References the
453 -- storage pool to be used for the corresponding collection. A value of
454 -- Empty means that the default pool is to be used. This is present
455 -- only in the root type, since derived types must have the same pool
456 -- as the parent type.
458 -- Barrier_Function (Node12)
459 -- Present in protected entries and entry families. This is the
460 -- subprogram declaration for the body of the function that returns
461 -- the value of the entry barrier.
463 -- Base_Type (synthesized)
464 -- Applies to all type and subtype entities. Returns the base type of a
465 -- type or subtype. The base type of a type is the type itself. The base
466 -- type of a subtype is the type that it constrains (which is always
467 -- a type entity, not some other subtype). Note that in the case of a
468 -- subtype of a private type, it is possible for the base type attribute
469 -- to return a private type, even if the subtype to which it applies is
470 -- non-private. See also Implementation_Base_Type. Note: it is allowed to
471 -- apply Base_Type to other than a type, in which case it simply returns
472 -- the entity unchanged.
474 -- Block_Node (Node11)
475 -- Present in block entities. Points to the identifier in the
476 -- Block_Statement itself. Used when retrieving the block construct
477 -- for finalization purposes, The block entity has an implicit label
478 -- declaration in the enclosing declarative part, and has otherwise
479 -- no direct connection in the tree with the block statement. The
480 -- link is to the identifier (which is an occurrence of the entity)
481 -- and not to the block_statement itself, because the statement may
482 -- be rewritten, e.g. in the process of removing dead code.
484 -- Body_Entity (Node19)
485 -- Present in package and generic package entities, points to the
486 -- corresponding package body entity if one is present.
488 -- Body_Needed_For_SAL (Flag40)
489 -- Present in package and subprogram entities that are compilation
490 -- units. Indicates that the source for the body must be included
491 -- when the unit is part of a standalone library.
493 -- C_Pass_By_Copy (Flag125) [implementation base type only]
494 -- Present in record types. Set if a pragma Convention for the record
495 -- type specifies convention C_Pass_By_Copy. This convention name is
496 -- treated as identical in all respects to convention C, except that
497 -- if it is specified for a record type, then the C_Pass_By_Copy flag
498 -- is set, and if a foreign convention subprogram has a formal of the
499 -- corresponding type, then the parameter passing mechanism will be
500 -- set to By_Copy (unless specifically overridden by an Import or
503 -- Can_Never_Be_Null (Flag38)
504 -- This flag is present in all entities, but can only be set in an object
505 -- which can never have a null value. This is set True for constant
506 -- access values initialized to a non-null value. This is also True for
507 -- all access parameters in Ada 83 and Ada 95 modes, and for access
508 -- parameters that explicitly exclude null in Ada 2005.
510 -- This is used to avoid unnecessary resetting of the Is_Known_Non_Null
511 -- flag for such entities. In Ada 2005 mode, this is also used when
512 -- determining subtype conformance of subprogram profiles to ensure
513 -- that two formals have the same null-exclusion status.
515 -- ??? This is also set on some access types, eg the Etype of the
516 -- anonymous access type of a controlling formal.
518 -- Can_Use_Internal_Rep (Flag229) [base type only]
519 -- Present in Access_Subprogram_Kind nodes. This flag is set by the
520 -- front end and used by the back end. False means that the back end
521 -- must represent the type in the same way as Convention-C types (and
522 -- other foreign-convention types). On many targets, this means that
523 -- the back end will use dynamically generated trampolines for nested
524 -- subprograms. True means that the back end can represent the type in
525 -- some internal way. On the aforementioned targets, this means that the
526 -- back end will not use dynamically generated trampolines. This flag
527 -- must be False if Has_Foreign_Convention is True; otherwise, the front
528 -- end is free to set the policy.
530 -- Setting this False in all cases corresponds to the traditional back
531 -- end strategy, where all access-to-subprogram types are represented the
532 -- same way, independent of the Convention. See also
533 -- Always_Compatible_Rep in Targparm.
535 -- Efficiency note: On targets that use dynamically generated
536 -- trampolines, False generally favors efficiency of top-level
537 -- subprograms, whereas True generally favors efficiency of nested
538 -- ones. On other targets, this flag has little or no effect on
539 -- efficiency. The front end should take this into account. In
540 -- particular, pragma Favor_Top_Level gives a hint that the flag should
543 -- Note: We considered using Convention-C for this purpose, but we need
544 -- this separate flag, because Convention-C implies that for
545 -- P'[Unrestricted_]Access, P also have convention C. Sometimes we want
546 -- to have Can_Use_Internal_Rep False for an access type, but allow P to
547 -- have convention Ada.
550 -- Present in all entities. This field contains an entry into the names
551 -- table that has the character string of the identifier, character
552 -- literal or operator symbol. See Namet for further details. Note that
553 -- throughout the processing of the front end, this name is the simple
554 -- unqualified name. However, just before gigi is called, a call is made
555 -- to Qualify_All_Entity_Names. This causes entity names to be qualified
556 -- using the encoding described in exp_dbug.ads, and from that point on
557 -- (including post gigi steps such as cross-reference generation), the
558 -- entities will contain the encoded qualified names.
560 -- Checks_May_Be_Suppressed (Flag31)
561 -- Present in all entities. Set if a pragma Suppress or Unsuppress
562 -- mentions the entity specifically in the second argument. If this
563 -- flag is set the Global_Entity_Suppress and Local_Entity_Suppress
564 -- tables must be consulted to determine if there actually is an active
565 -- Suppress or Unsuppress pragma that applies to the entity.
567 -- Class_Wide_Type (Node9)
568 -- Present in all type entities. For a tagged type or subtype, returns
569 -- the corresponding implicitly declared class-wide type. For a
570 -- class-wide type, returns itself. Set to Empty for non-tagged types.
572 -- Cloned_Subtype (Node16)
573 -- Present in E_Record_Subtype and E_Class_Wide_Subtype entities.
574 -- Each such entity can either have a Discriminant_Constraint, in
575 -- which case it represents a distinct type from the base type (and
576 -- will have a list of components and discrimants in the list headed by
577 -- First_Entity) or else no such constraint, in which case it will be a
578 -- copy of the base type.
580 -- o Each element of the list in First_Entity is copied from the base
581 -- type; in that case, this field is Empty.
583 -- o The list in First_Entity is shared with the base type; in that
584 -- case, this field points to that entity.
586 -- A record or classwide subtype may also be a copy of some other
587 -- subtype and share the entities in the First_Entity with that subtype.
588 -- In that case, this field points to that subtype.
590 -- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
591 -- this field. Note that this field ONLY appears in subtype entries, not
592 -- in type entries, it is not present, and it is an error to reference
593 -- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
596 -- This flag appears on all nodes, including entities, and indicates
597 -- that the node was created by the scanner or parser from the original
598 -- source. Thus for entities, it indicates that the entity is defined
599 -- in the original source program.
601 -- Component_Alignment (special field) [base type only]
602 -- Present in array and record entities. Contains a value of type
603 -- Component_Alignment_Kind indicating the alignment of components.
604 -- Set to Calign_Default normally, but can be overridden by use of
605 -- the Component_Alignment pragma. Note: this field is currently
606 -- stored in a non-standard way, see body for details.
608 -- Component_Bit_Offset (Uint11)
609 -- Present in record components (E_Component, E_Discriminant) if a
610 -- component clause applies to the component. First bit position of
611 -- given component, computed from the first bit and position values
612 -- given in the component clause. A value of No_Uint means that the
613 -- value is not yet known. The value can be set by the appearance of
614 -- an explicit component clause in a record representation clause,
615 -- or it can be set by the front-end in package Layout, or it can be
616 -- set by the backend. By the time backend processing is completed,
617 -- this field is always set. A negative value is used to represent
618 -- a value which is not known at compile time, and must be computed
619 -- at run-time (this happens if fields of a record have variable
620 -- lengths). See package Layout for details of these values.
622 -- Note: Component_Bit_Offset is redundant with respect to the fields
623 -- Normalized_First_Bit and Normalized_Position, and could in principle
624 -- be eliminated, but it is convenient in several situations, including
625 -- use in Gigi, to have this redundant field.
627 -- Component_Clause (Node13)
628 -- Present in record components and discriminants. If a record
629 -- representation clause is present for the corresponding record type a
630 -- that specifies a position for the component, then the Component_Clause
631 -- field of the E_Component entity points to the N_Component_Clause node.
632 -- Set to Empty if no record representation clause was present, or if
633 -- there was no specification for this component.
635 -- Component_Size (Uint22) [implementation base type only]
636 -- Present in array types. It contains the component size value for
637 -- the array. A value of No_Uint means that the value is not yet set.
638 -- The value can be set by the use of a component size clause, or
639 -- by the front end in package Layout, or by the backend. A negative
640 -- value is used to represent a value which is not known at compile
641 -- time, and must be computed at run-time (this happens if the type
642 -- of the component has a variable length size). See package Layout
643 -- for details of these values.
645 -- Component_Type (Node20) [implementation base type only]
646 -- Present in array types and string types. References component type.
648 -- Corresponding_Concurrent_Type (Node18)
649 -- Present in record types that are constructed by the expander to
650 -- represent task and protected types (Is_Concurrent_Record_Type flag
651 -- set True). Points to the entity for the corresponding task type or
654 -- Corresponding_Discriminant (Node19)
655 -- Present in discriminants of a derived type, when the discriminant is
656 -- used to constrain a discriminant of the parent type. Points to the
657 -- corresponding discriminant in the parent type. Otherwise it is Empty.
659 -- Corresponding_Equality (Node13)
660 -- Present in function entities for implicit inequality operators.
661 -- Denotes the explicit or derived equality operation that creates
662 -- the implicit inequality. Note that this field is not present in
663 -- other function entities, only in implicit inequality routines,
664 -- where Comes_From_Source is always False.
666 -- Corresponding_Protected_Entry (Node18)
667 -- Present in subprogram bodies. Set for subprogram bodies that implement
668 -- a protected type entry to point to the entity for the entry.
670 -- Corresponding_Record_Type (Node18)
671 -- Present in protected and task types and subtypes. References the
672 -- entity for the corresponding record type constructed by the expander
673 -- (see Exp_Ch9). This type is used to represent values of the task type.
675 -- Corresponding_Remote_Type (Node22)
676 -- Present in record types that describe the fat pointer structure for
677 -- Remote_Access_To_Subprogram types. References the original access
680 -- CR_Discriminant (Node23)
681 -- Present in discriminants of concurrent types. Denotes the homologous
682 -- discriminant of the corresponding record type. The CR_Discriminant is
683 -- created at the same time as the discriminal, and used to replace
684 -- occurrences of the discriminant within the type declaration.
686 -- Current_Use_Clause (Node27)
687 -- Present in packages and in types. For packages, denotes the use
688 -- package clause currently in scope that makes the package use_visible.
689 -- For types, it denotes the use_type clause that makes the operators of
690 -- the type visible. Used for more precise warning messages on redundant
693 -- Current_Value (Node9)
694 -- Present in all object entities. Set in E_Variable, E_Constant, formal
695 -- parameters and E_Loop_Parameter entities if we have trackable current
696 -- values. Set non-Empty if the (constant) current value of the variable
697 -- is known, This value is valid only for references from the same
698 -- sequential scope as the entity. The sequential scope of an entity
699 -- includes the immediate scope and any contained scopes that are package
700 -- specs, package bodies, blocks (at any nesting level) or statement
701 -- sequences in IF or loop statements.
703 -- Another related use of this field is to record information about the
704 -- value obtained from an IF or WHILE statement condition. If the IF or
705 -- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ",
706 -- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a
707 -- Current_Value field, RELOP is one of the six relational operators, and
708 -- VAL is a compile-time known value then the Current_Value field of OBJ
709 -- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node
710 -- of the relevant construct, and the Condition field of this can be
711 -- consulted to give information about the value of OBJ. For more details
712 -- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition.
714 -- Debug_Info_Off (Flag166)
715 -- Present in all entities. Set if a pragma Suppress_Debug_Info applies
716 -- to the entity, or if internal processing in the compiler determines
717 -- that suppression of debug information is desirable. Note that this
718 -- flag is only for use by the front end as part of the processing for
719 -- determining if Needs_Debug_Info should be set. The back end should
720 -- always test Needs_Debug_Info, it should never test Debug_Info_Off.
722 -- Debug_Renaming_Link (Node25)
723 -- Used to link the variable associated with a debug renaming declaration
724 -- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
725 -- details of the use of this field.
727 -- Declaration_Node (synthesized)
728 -- Applies to all entities. Returns the tree node for the construct that
729 -- declared the entity. Normally this is just the Parent of the entity.
730 -- One exception arises with child units, where the parent of the entity
731 -- is a selected component/defining program unit name. Another exception
732 -- is that if the entity is an incomplete type that has been completed,
733 -- then we obtain the declaration node denoted by the full type, i.e. the
734 -- full type declaration node. Also note that for subprograms, this
735 -- returns the {function,procedure}_specification, not the subprogram_
738 -- Default_Expr_Function (Node21)
739 -- Present in parameters. It holds the entity of the parameterless
740 -- function that is built to evaluate the default expression if it is
741 -- more complex than a simple identifier or literal. For the latter
742 -- simple cases or if there is no default value, this field is Empty.
744 -- Default_Expressions_Processed (Flag108)
745 -- A flag in subprograms (functions, operators, procedures) and in
746 -- entries and entry families used to indicate that default expressions
747 -- have been processed and to avoid multiple calls to process the
748 -- default expressions (see Freeze.Process_Default_Expressions), which
749 -- would not only waste time, but also generate false error messages.
751 -- Default_Value (Node20)
752 -- Present in formal parameters. Points to the node representing the
753 -- expression for the default value for the parameter. Empty if the
754 -- parameter has no default value (which is always the case for OUT
755 -- and IN OUT parameters in the absence of errors).
757 -- Delay_Cleanups (Flag114)
758 -- Present in entities that have finalization lists (subprograms
759 -- blocks, and tasks). Set if there are pending generic body
760 -- instantiations for the corresponding entity. If this flag is
761 -- set, then generation of cleanup actions for the corresponding
762 -- entity must be delayed, since the insertion of the generic body
763 -- may affect cleanup generation (see Inline for further details).
765 -- Delay_Subprogram_Descriptors (Flag50)
766 -- Present in entities for which exception subprogram descriptors
767 -- are generated (subprograms, package declarations and package
768 -- bodies). Present if there are pending generic body instantiations
769 -- for the corresponding entity. If this flag is set, then generation
770 -- of the subprogram descriptor for the corresponding enities must
771 -- be delayed, since the insertion of the generic body may add entries
772 -- to the list of handlers.
774 -- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
775 -- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
776 -- a block (in which case Delay_Subprogram_Descriptors is set for the
777 -- containing subprogram). In addition Delay_Subprogram_Descriptors is
778 -- set for a library level package declaration or body which contains
779 -- delayed instantiations (in this case the descriptor refers to the
780 -- enclosing elaboration procedure).
782 -- Delta_Value (Ureal18)
783 -- Present in fixed and decimal types. Points to a universal real
784 -- that holds value of delta for the type, as given in the declaration
785 -- or as inherited by a subtype or derived type.
787 -- Dependent_Instances (Elist8)
788 -- Present in packages that are instances. Holds list of instances
789 -- of inner generics. Used to place freeze nodes for those instances
790 -- after that of the current one, i.e. after the corresponding generic
793 -- Depends_On_Private (Flag14)
794 -- Present in all type entities. Set if the type is private or if it
795 -- depends on a private type.
797 -- Designated_Type (synthesized)
798 -- Applies to access types. Returns the designated type. Differs
799 -- from Directly_Designated_Type in that if the access type refers
800 -- to an incomplete type, and the full type is available, then this
801 -- full type is returned instead of the incomplete type.
803 -- Digits_Value (Uint17)
804 -- Present in floating point types and subtypes and decimal types and
805 -- subtypes. Contains the Digits value specified in the declaration.
807 -- Direct_Primitive_Operations (Elist10)
808 -- Present in tagged types and subtypes (including synchronized types),
809 -- in tagged private types and in tagged incomplete types. Element list
810 -- of entities for primitive operations of the tagged type. Not present
811 -- in untagged types. In order to follow the C++ ABI, entities of
812 -- primitives that come from source must be stored in this list in the
813 -- order of their occurrence in the sources. For incomplete types the
814 -- list is always empty.
816 -- Directly_Designated_Type (Node20)
817 -- Present in access types. This field points to the type that is
818 -- directly designated by the access type. In the case of an access
819 -- type to an incomplete type, this field references the incomplete
820 -- type. Directly_Designated_Type is typically used in implementing the
821 -- static semantics of the language; in implementing dynamic semantics,
822 -- we typically want the full view of the designated type. The function
823 -- Designated_Type obtains this full type in the case of access to an
826 -- Discard_Names (Flag88)
827 -- Present in types and exception entities. Set if pragma Discard_Names
828 -- applies to the entity. It is also set for declarative regions and
829 -- package specs for which a Discard_Names pragma with zero arguments
830 -- has been encountered. The purpose of setting this flag is to be able
831 -- to set the Discard_Names attribute on enumeration types declared
832 -- after the pragma within the same declarative region. This flag is
833 -- set to False if a Keep_Names pragma appears for an enumeration type.
835 -- Discriminal (Node17)
836 -- Present in discriminants (Discriminant formal: GNAT's first
837 -- coinage). The entity used as a formal parameter that corresponds
838 -- to a discriminant. See section "Handling of Discriminants" for
839 -- full details of the use of discriminals.
841 -- Discriminal_Link (Node10)
842 -- Present in discriminals (which have an Ekind of E_In_Parameter,
843 -- or E_Constant), points back to corresponding discriminant.
845 -- Discriminant_Checking_Func (Node20)
846 -- Present in components. Points to the defining identifier of the
847 -- function built by the expander returns a Boolean indicating whether
848 -- the given record component exists for the current discriminant
851 -- Discriminant_Constraint (Elist21)
852 -- Present in entities whose Has_Discriminants flag is set (concurrent
853 -- types, subtypes, record types and subtypes, private types and
854 -- subtypes, limited private types and subtypes and incomplete types).
855 -- It is an error to reference the Discriminant_Constraint field if
856 -- Has_Discriminants is False.
858 -- If the Is_Constrained flag is set, Discriminant_Constraint points
859 -- to an element list containing the discriminant constraints in the
860 -- same order in which the discriminants are declared.
862 -- If the Is_Constrained flag is not set but the discriminants of the
863 -- unconstrained type have default initial values then this field
864 -- points to an element list giving these default initial values in
865 -- the same order in which the discriminants are declared. Note that
866 -- in this case the entity cannot be a tagged record type, because
867 -- discriminants in this case cannot have defaults.
869 -- If the entity is a tagged record implicit type, then this field is
870 -- inherited from the first subtype (so that the itype is subtype
871 -- conformant with its first subtype, which is needed when the first
872 -- subtype overrides primitive operations inherited by the implicit
875 -- In all other cases Discriminant_Constraint contains the empty
876 -- Elist (ie it is initialized with a call to New_Elmt_List).
878 -- Discriminant_Default_Value (Node20)
879 -- Present in discriminants. Points to the node representing the
880 -- expression for the default value of the discriminant. Set to
881 -- Empty if the discriminant has no default value.
883 -- Discriminant_Number (Uint15)
884 -- Present in discriminants. Gives the ranking of a discriminant in
885 -- the list of discriminants of the type, i.e. a sequential integer
886 -- index starting at 1 and ranging up to number of discriminants.
888 -- Dispatch_Table_Wrappers (Elist26) [implementation base type only]
889 -- Present in E_Record_Type and E_Record_Subtype entities. Set in library
890 -- level tagged type entities if we are generating statically allocated
891 -- dispatch tables. Points to the list of dispatch table wrappers
892 -- associated with the tagged type. For a non-tagged record, contains
895 -- DTC_Entity (Node16)
896 -- Present in function and procedure entities. Set to Empty unless
897 -- the subprogram is dispatching in which case it references the
898 -- Dispatch Table pointer Component. That is to say the component _tag
899 -- for regular Ada tagged types, for CPP_Class types and their
900 -- descendants this field points to the component entity in the record
901 -- that is the Vtable pointer for the Vtable containing the entry that
902 -- references the subprogram.
904 -- DT_Entry_Count (Uint15)
905 -- Present in E_Component entities. Only used for component marked
906 -- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
908 -- DT_Offset_To_Top_Func (Node25)
909 -- Present in E_Component entities. Only used for component marked
910 -- Is_Tag. If present it stores the Offset_To_Top function used to
911 -- provide this value in tagged types whose ancestor has discriminants.
913 -- DT_Position (Uint15)
914 -- Present in function and procedure entities which are dispatching
915 -- (should not be referenced without first checking that flag
916 -- Is_Dispatching_Operation is True). Contains the offset into
917 -- the Vtable for the entry that references the subprogram.
920 -- Present in all entities. Contains a value of the enumeration type
921 -- Entity_Kind declared in a subsequent section in this spec.
923 -- Elaborate_Body_Desirable (Flag210)
924 -- Present in package entities. Set if the elaboration circuitry detects
925 -- a case where there is a package body that modifies one or more visible
926 -- entities in the package spec and there is no explicit Elaborate_Body
927 -- pragma for the package. This information is passed on to the binder,
928 -- which attempts, but does not promise, to elaborate the body as close
929 -- to the spec as possible.
931 -- Elaboration_Entity (Node13)
932 -- Present in generic and non-generic package and subprogram entities.
933 -- This is a counter associated with the unit that is initially set to
934 -- zero, is incremented when an elaboration request for the unit is
935 -- made, and is decremented when a finalization request for the unit
936 -- is made. This is used for three purposes. First, it is used to
937 -- implement access before elaboration checks (the counter must be
938 -- non-zero to call a subprogram at elaboration time). Second, it is
939 -- used to guard against repeated execution of the elaboration code.
940 -- Third, it is used to ensure that the finalization code is executed
941 -- only after all clients have requested it.
943 -- Note that we always allocate this counter, and set this field, but
944 -- we do not always actually use it. It is only used if it is needed
945 -- for access before elaboration use (see Elaboration_Entity_Required
946 -- flag) or if either the spec or the body has elaboration code. If
947 -- neither of these two conditions holds, then the entity is still
948 -- allocated (since we don't know early enough whether or not there
949 -- is elaboration code), but is simply not used for any purpose.
951 -- Elaboration_Entity_Required (Flag174)
952 -- Present in generic and non-generic package and subprogram entities.
953 -- Set only if Elaboration_Entity is non-Empty to indicate that the
954 -- counter is required to be non-zero even if there is no other
955 -- elaboration code. This occurs when the Elaboration_Entity counter
956 -- is used for access before elaboration checks. If the counter is
957 -- only used to prevent multiple execution of the elaboration code,
958 -- then if there is no other elaboration code, obviously there is no
959 -- need to set the flag.
961 -- Enclosing_Scope (Node18)
962 -- Present in labels. Denotes the innermost enclosing construct that
963 -- contains the label. Identical to the scope of the label, except for
964 -- labels declared in the body of an accept statement, in which case the
965 -- entry_name is the Enclosing_Scope. Used to validate goto's within
966 -- accept statements.
968 -- Entry_Accepted (Flag152)
969 -- Present in E_Entry and E_Entry_Family entities. Set if there is
970 -- at least one accept for this entry in the task body. Used to
971 -- generate warnings for missing accepts.
973 -- Entry_Bodies_Array (Node15)
974 -- Present in protected types for which Has_Entries is true.
975 -- This is the defining identifier for the array of entry body
976 -- action procedures and barrier functions used by the runtime to
977 -- execute the user code associated with each entry.
979 -- Entry_Cancel_Parameter (Node23)
980 -- Present in blocks. This only applies to a block statement for
981 -- which the Is_Asynchronous_Call_Block flag is set. It
982 -- contains the defining identifier of an object that must be
983 -- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
984 -- call in the cleanup handler added to the block by
985 -- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
986 -- object for task entry calls and a Communications_Block object
987 -- in the case of protected entry calls. In both cases the objects
988 -- are declared in outer scopes to this block.
990 -- Entry_Component (Node11)
991 -- Present in formal parameters (in, in out and out parameters). Used
992 -- only for formals of entries. References the corresponding component
993 -- of the entry parameter record for the entry.
995 -- Entry_Formal (Node16)
996 -- Present in components of the record built to correspond to entry
997 -- parameters. This field points from the component to the formal. It
998 -- is the back pointer corresponding to Entry_Component.
1000 -- Entry_Index_Constant (Node18)
1001 -- Present in an entry index parameter. This is an identifier that
1002 -- eventually becomes the name of a constant representing the index
1003 -- of the entry family member whose entry body is being executed. Used
1004 -- to expand references to the entry index specification identifier.
1006 -- Entry_Index_Type (synthesized)
1007 -- Applies to an entry family. Denotes Etype of the subtype indication
1008 -- in the entry declaration. Used to resolve the index expression in an
1009 -- accept statement for a member of the family, and in the prefix of
1010 -- 'COUNT when it applies to a family member.
1012 -- Contract (Node24)
1013 -- Present in entries, and in subprogram and generic subprogram entities.
1014 -- Points to the contract of the entity, holding both pre- and
1015 -- postconditions as well as test-cases.
1017 -- Entry_Parameters_Type (Node15)
1018 -- Present in entries. Points to the access-to-record type that is
1019 -- constructed by the expander to hold a reference to the parameter
1020 -- values. This reference is manipulated (as an address) by the
1021 -- tasking runtime. The designated record represents a packaging
1022 -- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
1023 -- for further details). Entry_Parameters_Type is Empty if the entry
1024 -- has no parameters.
1026 -- Enumeration_Pos (Uint11)
1027 -- Present in enumeration literals. Contains the position number
1028 -- corresponding to the value of the enumeration literal.
1030 -- Enumeration_Rep (Uint12)
1031 -- Present in enumeration literals. Contains the representation that
1032 -- corresponds to the value of the enumeration literal. Note that
1033 -- this is normally the same as Enumeration_Pos except in the presence
1034 -- of representation clauses, where Pos will still represent the
1035 -- position of the literal within the type and Rep will have be the
1036 -- value given in the representation clause.
1038 -- Enumeration_Rep_Expr (Node22)
1039 -- Present in enumeration literals. Points to the expression in an
1040 -- associated enumeration rep clause that provides the representation
1041 -- value for this literal. Empty if no enumeration rep clause for this
1042 -- literal (or if rep clause does not have an entry for this literal,
1043 -- an error situation). This is also used to catch duplicate entries
1044 -- for the same literal.
1046 -- Enum_Pos_To_Rep (Node23)
1047 -- Present in enumeration types (but not enumeration subtypes). Set to
1048 -- Empty unless the enumeration type has a non-standard representation
1049 -- (i.e. at least one literal has a representation value different from
1050 -- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
1051 -- array constructed when the type is frozen that maps Pos values to
1052 -- corresponding Rep values. The index type of this array is Natural,
1053 -- and the component type is a suitable integer type that holds the
1054 -- full range of representation values.
1056 -- Equivalent_Type (Node18)
1057 -- Present in class wide types and subtypes, access to protected
1058 -- subprogram types, and in exception types. For a classwide type, it
1059 -- is always Empty. For a class wide subtype, it points to an entity
1060 -- created by the expander which gives Gigi an easily understandable
1061 -- equivalent of the class subtype with a known size (given by an
1062 -- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
1063 -- details. For E_Exception_Type, this points to the record containing
1064 -- the data necessary to represent exceptions (for further details, see
1065 -- System.Standard_Library. For access_to_protected subprograms, it
1066 -- denotes a record that holds pointers to the operation and to the
1067 -- protected object. For remote Access_To_Subprogram types, it denotes
1068 -- the record that is the fat pointer representation of an RAST.
1071 -- Present in all types and subtypes, and also for components, constants,
1072 -- and variables, including exceptions where it refers to the static data
1073 -- allocated for an exception. Contains the Object_Size of the type or of
1074 -- the object. A value of zero indicates that the value is not yet known.
1076 -- For the case of components where a component clause is present, the
1077 -- value is the value from the component clause, which must be non-
1078 -- negative (but may be zero, which is acceptable for the case of
1079 -- a type with only one possible value). It is also possible for Esize
1080 -- of a component to be set without a component clause present, which
1081 -- means that the component size is specified, but not the position.
1082 -- See also RM_Size and the section on "Handling of Type'Size Values".
1083 -- During gigi processing, the value is back annotated for all zero
1084 -- values, so that after the call to gigi, the value is properly set.
1087 -- Present in all entities. Represents the type of the entity, which
1088 -- is itself another entity. For a type entity, points to the parent
1089 -- type for a derived type, or if the type is not derived, points to
1090 -- itself. For a subtype entity, Etype points to the base type. For
1091 -- a class wide type, points to the corresponding specific type. For a
1092 -- subprogram or subprogram type, Etype has the return type of a function
1093 -- or is set to Standard_Void_Type to represent a procedure.
1095 -- Note one obscure case: for pragma Default_Storage_Pool (null), the
1096 -- Etype of the N_Null node is Empty.
1098 -- Exception_Code (Uint22)
1099 -- Present in exception entities. Set to zero unless either an
1100 -- Import_Exception or Export_Exception pragma applies to the
1101 -- pragma and specifies a Code value. See description of these
1102 -- pragmas for details. Note that this field is relevant only if
1103 -- Is_VMS_Exception is set.
1105 -- Extra_Formal (Node15)
1106 -- Present in formal parameters in the non-generic case. Certain
1107 -- parameters require extra implicit information to be passed (e.g. the
1108 -- flag indicating if an unconstrained variant record argument is
1109 -- constrained, and the accessibility level for access parameters. See
1110 -- description of Extra_Constrained, Extra_Accessibility fields for
1111 -- further details. Extra formal parameters are constructed to represent
1112 -- these values, and chained to the end of the list of formals using the
1113 -- Extra_Formal field (i.e. the Extra_Formal field of the last "real"
1114 -- formal points to the first extra formal, and the Extra_Formal field of
1115 -- each extra formal points to the next one, with Empty indicating the
1116 -- end of the list of extra formals.
1118 -- Extra_Formals (Node28)
1119 -- Applies to subprograms and subprogram types, and also in entries
1120 -- and entry families. Returns first extra formal of the subprogram
1121 -- or entry. Returns Empty if there are no extra formals.
1123 -- Extra_Accessibility (Node13)
1124 -- Present in formal parameters in the non-generic case. Normally Empty,
1125 -- but if expansion is active, and a parameter is one for which a
1126 -- dynamic accessibility check is required, then an extra formal of type
1127 -- Natural is created (see description of field Extra_Formal), and the
1128 -- Extra_Accessibility field of the formal parameter points to the entity
1129 -- for this extra formal. Also present in variables when compiling
1130 -- receiving stubs. In this case, a non Empty value means that this
1131 -- variable's accessibility depth has been transmitted by the caller and
1132 -- must be retrieved through the entity designed by this field instead of
1135 -- Extra_Accessibility_Of_Result (Node19)
1136 -- Present in (non-generic) Function, Operator, and Subprogram_Type
1137 -- entities. Normally Empty, but if expansion is active, and a function
1138 -- is one for which "the accessibility level of the result ... determined
1139 -- by the point of call" (AI05-0234) is needed, then an extra formal of
1140 -- subtype Natural is created (see description of field Extra_Formal),
1141 -- and the Extra_Accessibility_Of_Result field of the function points to
1142 -- the entity for this extra formal.
1144 -- Extra_Constrained (Node23)
1145 -- Present in formal parameters in the non-generic case. Normally Empty,
1146 -- but if expansion is active and a parameter is one for which a dynamic
1147 -- indication of its constrained status is required, then an extra formal
1148 -- of type Boolean is created (see description of field Extra_Formal),
1149 -- and the Extra_Constrained field of the formal parameter points to the
1150 -- entity for this extra formal. Also present in variables when compiling
1151 -- receiving stubs. In this case, a non empty value means that this
1152 -- variable's constrained status has been transmitted by the caller and
1153 -- must be retrieved through the entity designed by this field instead of
1156 -- Finalization_Master (Node23) [root type only]
1157 -- Present in access-to-controlled or access-to-class-wide types. The
1158 -- field contains the entity of the finalization master which handles
1159 -- dynamically allocated controlled objects referenced by the access
1160 -- type. Empty for access-to-subprogram types. Empty for access types
1161 -- whose designated type does not need finalization actions.
1163 -- Finalize_Storage_Only (Flag158) [base type only]
1164 -- Present in all types. Set on direct controlled types to which a
1165 -- valid Finalize_Storage_Only pragma applies. This flag is also set on
1166 -- composite types when they have at least one controlled component and
1167 -- all their controlled components are Finalize_Storage_Only. It is also
1168 -- inherited by type derivation except for direct controlled types where
1169 -- the Finalize_Storage_Only pragma is required at each level of
1172 -- Finalizer (Node24)
1173 -- Applies to package declarations and bodies. Contains the entity of the
1174 -- library-level program which finalizes all package-level controlled
1177 -- First_Component (synthesized)
1178 -- Applies to record types. Returns the first component by following the
1179 -- chain of declared entities for the record until a component is found
1180 -- (one with an Ekind of E_Component). The discriminants are skipped. If
1181 -- the record is null, then Empty is returned.
1183 -- First_Component_Or_Discriminant (synthesized)
1184 -- Similar to First_Component, but discriminants are not skipped, so will
1185 -- find the first discriminant if discriminants are present.
1187 -- First_Entity (Node17)
1188 -- Present in all entities which act as scopes to which a list of
1189 -- associated entities is attached (blocks, class subtypes and types,
1190 -- entries, functions, loops, packages, procedures, protected objects,
1191 -- record types and subtypes, private types, task types and subtypes).
1192 -- Points to a list of associated entities using the Next_Entity field
1193 -- as a chain pointer with Empty marking the end of the list.
1195 -- First_Exit_Statement (Node8)
1196 -- Present in E_Loop entity. The exit statements for a loop are chained
1197 -- (in reverse order of appearance) using this field to point to the
1198 -- first entry in the chain (last exit statement in the loop). The
1199 -- entries are chained through the Next_Exit_Statement field of the
1200 -- N_Exit_Statement node with Empty marking the end of the list.
1202 -- First_Formal (synthesized)
1203 -- Applies to subprograms and subprogram types, and also in entries
1204 -- and entry families. Returns first formal of the subprogram or entry.
1205 -- The formals are the first entities declared in a subprogram or in
1206 -- a subprogram type (the designated type of an Access_To_Subprogram
1207 -- definition) or in an entry.
1209 -- First_Formal_With_Extras (synthesized)
1210 -- Applies to subprograms and subprogram types, and also in entries
1211 -- and entry families. Returns first formal of the subprogram or entry.
1212 -- Returns Empty if there are no formals. The list returned includes
1213 -- all the extra formals (see description of Extra_Formals field).
1215 -- First_Index (Node17)
1216 -- Present in array types and subtypes and in string types and subtypes.
1217 -- By introducing implicit subtypes for the index constraints, we have
1218 -- the same structure for constrained and unconstrained arrays, subtype
1219 -- marks and discrete ranges are both represented by a subtype. This
1220 -- function returns the tree node corresponding to an occurrence of the
1221 -- first index (NOT the entity for the type). Subsequent indexes are
1222 -- obtained using Next_Index. Note that this field is present for the
1223 -- case of string literal subtypes, but is always Empty.
1225 -- First_Literal (Node17)
1226 -- Present in all enumeration types, including character and boolean
1227 -- types. This field points to the first enumeration literal entity
1228 -- for the type (i.e. it is set to First (Literals (N)) where N is
1229 -- the enumeration type definition node. A special case occurs with
1230 -- standard character and wide character types, where this field is
1231 -- Empty, since there are no enumeration literal lists in these cases.
1232 -- Note that this field is set in enumeration subtypes, but it still
1233 -- points to the first literal of the base type in this case.
1235 -- First_Optional_Parameter (Node14)
1236 -- Present in (non-generic) function and procedure entities. Set to a
1237 -- non-null value only if a pragma Import_Function, Import_Procedure
1238 -- or Import_Valued_Procedure specifies a First_Optional_Parameter
1239 -- argument, in which case this field points to the parameter entity
1240 -- corresponding to the specified parameter.
1242 -- First_Private_Entity (Node16)
1243 -- Present in all entities containing private parts (packages, protected
1244 -- types and subtypes, task types and subtypes). The entities on the
1245 -- entity chain are in order of declaration, so the entries for private
1246 -- entities are at the end of the chain. This field points to the first
1247 -- entity for the private part. It is Empty if there are no entities
1248 -- declared in the private part or if there is no private part.
1250 -- First_Rep_Item (Node6)
1251 -- Present in all entities. If non-empty, points to a linked list of
1252 -- representation pragmas nodes and representation clause nodes that
1253 -- apply to the entity, linked using Next_Rep_Item, with Empty marking
1254 -- the end of the list. In the case of derived types and subtypes, the
1255 -- new entity inherits the chain at the point of declaration. This means
1256 -- that it is possible to have multiple instances of the same kind of rep
1257 -- item on the chain, in which case it is the first one that applies to
1260 -- Note: pragmas that can apply to more than one overloadable entity,
1261 -- (Convention, Interface, Inline, Inline_Always, Import, Export,
1262 -- External) are never present on this chain when they apply to
1263 -- overloadable entities, since it is impossible for a given pragma
1264 -- to be on more than one chain at a time.
1266 -- For most representation items, the representation information is
1267 -- reflected in other fields and flags in the entity. For example if a
1268 -- record representation clause is present, the component entities
1269 -- reflect the specified information. However, there are some items that
1270 -- are only reflected in the chain. These include:
1272 -- Alignment attribute definition clause
1273 -- Machine_Attribute pragma
1274 -- Link_Alias pragma
1275 -- Linker_Section pragma
1276 -- Weak_External pragma
1278 -- If any of these items are present, then the flag Has_Gigi_Rep_Item is
1279 -- set, indicating that Gigi should search the chain.
1281 -- Other representation items are included in the chain so that error
1282 -- messages can easily locate the relevant nodes for posting errors.
1283 -- Note in particular that size clauses are present only for this
1284 -- purpose, and should only be accessed if Has_Size_Clause is set.
1286 -- Float_Rep (Uint10)
1287 -- Present in floating-point entities. Contains a value of type
1288 -- Float_Rep_Kind. Together with the Digits_Value uniquely defines
1289 -- the floating-point representation to be used.
1291 -- Freeze_Node (Node7)
1292 -- Present in all entities. If there is an associated freeze node for the
1293 -- entity, this field references this freeze node. If no freeze node is
1294 -- associated with the entity, then this field is Empty. See package
1295 -- Freeze for further details.
1297 -- From_With_Type (Flag159)
1298 -- Present in package and type entities. Indicates that the entity
1299 -- appears in a With_Type clause in the context of some other unit,
1300 -- either as the prefix (which must be a package), or as a type name.
1301 -- The package can only be used to retrieve such a type, and the type
1302 -- can be used only in component declarations and access definitions.
1303 -- The With_Type clause is used to construct mutually recursive
1304 -- types, i.e. record types (Java classes) that hold pointers to each
1305 -- other. If such a type is an access type, it has no explicit freeze
1306 -- node, so that the back-end does not attempt to elaborate it.
1307 -- Currently this flag is also used to implement Ada 2005 (AI-50217).
1308 -- It will be renamed to From_Limited_With after removal of the current
1309 -- GNAT with_type clause???
1311 -- Full_View (Node11)
1312 -- Present in all type and subtype entities and in deferred constants.
1313 -- References the entity for the corresponding full type declaration.
1314 -- For all types other than private and incomplete types, this field
1315 -- always contains Empty. If an incomplete type E1 is completed by a
1316 -- private type E2 whose full type declaration entity is E3 then the
1317 -- full view of E1 is E2, and the full view of E2 is E3. See also
1320 -- Generic_Homonym (Node11)
1321 -- Present in generic packages. The generic homonym is the entity of
1322 -- a renaming declaration inserted in every generic unit. It is used
1323 -- to resolve the name of a local entity that is given by a qualified
1324 -- name, when the generic entity itself is hidden by a local name.
1326 -- Generic_Renamings (Elist23)
1327 -- Present in package and subprogram instances. Holds mapping that
1328 -- associates generic parameters with the corresponding instances, in
1329 -- those cases where the instance is an entity.
1331 -- Handler_Records (List10)
1332 -- Present in subprogram and package entities. Points to a list of
1333 -- identifiers referencing the handler record entities for the
1334 -- corresponding unit.
1336 -- Has_Aliased_Components (Flag135) [implementation base type only]
1337 -- Present in array type entities. Indicates that the component type
1338 -- of the array is aliased.
1340 -- Has_Alignment_Clause (Flag46)
1341 -- Present in all type entities and objects. Indicates if an alignment
1342 -- clause has been given for the entity. If set, then Alignment_Clause
1343 -- returns the N_Attribute_Definition node for the alignment attribute
1344 -- definition clause. Note that it is possible for this flag to be False
1345 -- even when Alignment_Clause returns non_Empty (this happens in the case
1346 -- of derived type declarations).
1348 -- Has_All_Calls_Remote (Flag79)
1349 -- Present in all library unit entities. Set true if the library unit
1350 -- has an All_Calls_Remote pragma. Note that such entities must also
1351 -- be RCI entities, so the flag Is_Remote_Call_Interface will always
1352 -- be set if this flag is set.
1354 -- Has_Anon_Block_Suffix (Flag201)
1355 -- Present in all entities. Set if the entity is nested within one or
1356 -- more anonymous blocks and the Chars field contains a name with an
1357 -- anonymous block suffix (see Exp_Dbug for further details).
1359 -- Has_Anonymous_Master (Flag253)
1360 -- Present in units (top-level functions and procedures, library-level
1361 -- packages). Set to True if the associated unit contains a heterogeneous
1362 -- finalization master. The master's name is of the form <unit>AM and it
1363 -- services anonymous access-to-controlled types with an undetermined
1366 -- Has_Atomic_Components (Flag86) [implementation base type only]
1367 -- Present in all types and objects. Set only for an array type or
1368 -- an array object if a valid pragma Atomic_Components applies to the
1369 -- type or object. Note that in the case of an object, this flag is
1370 -- only set on the object if there was an explicit pragma for the
1371 -- object. In other words, the proper test for whether an object has
1372 -- atomic components is to see if either the object or its base type
1373 -- has this flag set. Note that in the case of a type, the pragma will
1374 -- be chained to the rep item chain of the first subtype in the usual
1377 -- Has_Attach_Handler (synthesized)
1378 -- Applies to record types that are constructed by the expander to
1379 -- represent protected types. Returns True if there is at least one
1380 -- Attach_Handler pragma in the corresponding specification.
1382 -- Has_Biased_Representation (Flag139)
1383 -- Present in discrete types (where it applies to the type'size value),
1384 -- and to objects (both stand-alone and components), where it applies to
1385 -- the size of the object from a size or record component clause. In
1386 -- all cases it indicates that the size in question is smaller than
1387 -- would normally be required, but that the size requirement can be
1388 -- satisfied by using a biased representation, in which stored values
1389 -- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
1390 -- reduce the required size. For example, a type with a range of 1..2
1391 -- takes one bit, using 0 to represent 1 and 1 to represent 2.
1393 -- Note that in the object and component cases, the flag is only set if
1394 -- the type is unbiased, but the object specifies a smaller size than the
1395 -- size of the type, forcing biased representation for the object, but
1396 -- the subtype is still an unbiased type.
1398 -- Has_Completion (Flag26)
1399 -- Present in all entities that require a completion (functions,
1400 -- procedures, private types, limited private types, incomplete types,
1401 -- constants and packages that require a body). The flag is set if the
1402 -- completion has been encountered and analyzed.
1404 -- Has_Completion_In_Body (Flag71)
1405 -- Present in all entities for types and subtypes. Set only in "Taft
1406 -- amendment types" (incomplete types whose full declaration appears in
1407 -- the package body).
1409 -- Has_Complex_Representation (Flag140) [implementation base type only]
1410 -- Present in all type entities. Set only for a record base type to
1411 -- which a valid pragma Complex_Representation applies.
1413 -- Has_Component_Size_Clause (Flag68) [implementation base type only]
1414 -- Present in all type entities. Set if a component size clause is
1415 -- present for the given type. Note that this flag can be False even
1416 -- if Component_Size is non-zero (happens in the case of derived types).
1418 -- Has_Constrained_Partial_View (Flag187)
1419 -- Present in private type and their completions, when the private
1420 -- type has no discriminants and the full view has discriminants with
1421 -- defaults. In Ada 2005 heap-allocated objects of such types are not
1422 -- constrained, and can change their discriminants with full assignment.
1423 -- Sem_Util.Effectively_Has_Constrained_Partial_View should be always
1424 -- used by callers, rather than reading this attribute directly.
1426 -- Has_Contiguous_Rep (Flag181)
1427 -- Present in enumeration types. True if the type as a representation
1428 -- clause whose entries are successive integers.
1430 -- Has_Controlling_Result (Flag98)
1431 -- Present in E_Function entities. True if the function is a primitive
1432 -- function of a tagged type which can dispatch on result.
1434 -- Has_Controlled_Component (Flag43) [base type only]
1435 -- Present in all type and subtype entities. Set only for composite type
1436 -- entities which contain a component that either is a controlled type,
1437 -- or itself contains controlled component (i.e. either Is_Controlled or
1438 -- Has_Controlled_Component is set for at least one component).
1440 -- Has_Convention_Pragma (Flag119)
1441 -- Present in all entities. Set true for an entity for which a valid
1442 -- Convention, Import, or Export pragma has been given. Used to prevent
1443 -- more than one such pragma appearing for a given entity (RM B.1(45)).
1445 -- Has_Delayed_Aspects (Flag200) Present in all entities. Set true if the
1446 -- Rep_Item chain for the entity has one or more N_Aspect_Definition
1447 -- nodes chained which are not to be evaluated till the freeze point.
1448 -- The aspect definition expression clause has been preanalyzed to get
1449 -- visibility at the point of use, but no other action has been taken.
1451 -- Has_Delayed_Freeze (Flag18)
1452 -- Present in all entities. Set to indicate that an explicit freeze
1453 -- node must be generated for the entity at its freezing point. See
1454 -- separate section ("Delayed Freezing and Elaboration") for details.
1456 -- Has_Default_Aspect (Flag39) [base type only]
1457 -- Present in entities for types and subtypes, set for scalar types with
1458 -- a Default_Value aspect and array types with a Default_Component_Value
1459 -- apsect. If this flag is set, then a corresponding aspect specification
1460 -- node will be present on the rep item chain for the entity.
1462 -- Has_Discriminants (Flag5)
1463 -- Present in all types and subtypes. For types that are allowed to have
1464 -- discriminants (record types and subtypes, task types and subtypes,
1465 -- protected types and subtypes, private types, limited private types,
1466 -- and incomplete types), indicates if the corresponding type or subtype
1467 -- has a known discriminant part. Always false for all other types.
1469 -- Has_Dispatch_Table (Flag220)
1470 -- Present in E_Record_Types that are tagged. Set to indicate that the
1471 -- corresponding dispatch table is already built. This flag is used to
1472 -- avoid duplicate construction of library level dispatch tables (because
1473 -- the declaration of library level objects cause premature construction
1474 -- of the table); otherwise the code that builds the table is added at
1475 -- the end of the list of declarations of the package.
1477 -- Has_Entries (synthesized)
1478 -- Applies to concurrent types. True if any entries are declared
1479 -- within the task or protected definition for the type.
1481 -- Has_Enumeration_Rep_Clause (Flag66)
1482 -- Present in enumeration types. Set if an enumeration representation
1483 -- clause has been given for this enumeration type. Used to prevent more
1484 -- than one enumeration representation clause for a given type. Note
1485 -- that this does not imply a representation with holes, since the rep
1486 -- clause may merely confirm the default 0..N representation.
1488 -- Has_External_Tag_Rep_Clause (Flag110)
1489 -- Present in tagged types. Set if an external_tag rep. clause has been
1490 -- given for this type. Use to avoid the generation of the default
1493 -- Has_Exit (Flag47)
1494 -- Present in loop entities. Set if the loop contains an exit statement.
1496 -- Has_Foreign_Convention (synthesized)
1497 -- Applies to all entities. Determines if the Convention for the
1498 -- entity is a foreign convention (i.e. is other than Convention_Ada,
1499 -- Convention_Intrinsic, Convention_Entry or Convention_Protected).
1501 -- Has_Forward_Instantiation (Flag175)
1502 -- Present in package entities. Set true for packages that contain
1503 -- instantiations of local generic entities, before the corresponding
1504 -- generic body has been seen. If a package has a forward instantiation,
1505 -- we cannot inline subprograms appearing in the same package because
1506 -- the placement requirements of the instance will conflict with the
1507 -- linear elaboration of front-end inlining.
1509 -- Has_Fully_Qualified_Name (Flag173)
1510 -- Present in all entities. Set True if the name in the Chars field has
1511 -- been replaced by the fully qualified name, as used for debug output.
1512 -- See Exp_Dbug for a full description of the use of this flag and also
1513 -- the related flag Has_Qualified_Name.
1515 -- Has_Gigi_Rep_Item (Flag82)
1516 -- Present in all entities. Set if the rep item chain (referenced by
1517 -- First_Rep_Item and linked through the Next_Rep_Item chain) contains a
1518 -- representation item that needs to be specially processed by Gigi, i.e.
1519 -- one of the following items:
1521 -- Machine_Attribute pragma
1522 -- Linker_Alias pragma
1523 -- Linker_Section pragma
1524 -- Linker_Constructor pragma
1525 -- Linker_Destructor pragma
1526 -- Weak_External pragma
1528 -- If this flag is set, then Gigi should scan the rep item chain to
1529 -- process any of these items that appear. At least one such item will
1532 -- Has_Homonym (Flag56)
1533 -- Present in all entities. Set if an entity has a homonym in the same
1534 -- scope. Used by Gigi to generate unique names for such entities.
1536 -- Has_Implicit_Dereference (Flag251)
1537 -- Present in types and discriminants. Set if the type has an aspect
1538 -- Implicit_Dereference. Set also on the discriminant named in the aspect
1539 -- clause, to simplify type resolution.
1541 -- Has_Initial_Value (Flag219)
1542 -- Present in entities for variables and out parameters. Set if there
1543 -- is an explicit initial value expression in the declaration of the
1544 -- variable. Note that this is set only if this initial value is
1545 -- explicit, it is not set for the case of implicit initialization
1546 -- of access types or controlled types. Always set to False for out
1547 -- parameters. Also present in entities for in and in-out parameters,
1548 -- but always false in these cases.
1550 -- Has_Interrupt_Handler (synthesized)
1551 -- Applies to all protected type entities. Set if the protected type
1552 -- definition contains at least one procedure to which a pragma
1553 -- Interrupt_Handler applies.
1555 -- Has_Invariants (Flag232)
1556 -- Present in all type entities and in subprogram entities. Set True in
1557 -- private types if an Invariant or Invariant'Class aspect applies to the
1558 -- type, or if the type inherits one or more Invariant'Class aspects.
1559 -- Also set in the corresponding full type. Note: if this flag is set
1560 -- True, then usually the Invariant_Procedure attribute is set once the
1561 -- type is frozen, however this may not be true in some error situations.
1562 -- Note that it might be the full type which has inheritable invariants,
1563 -- and then the flag will also be set in the private type. Also set in
1564 -- the invariant procedure entity, to distinguish it among entries in the
1565 -- Subprograms_For_Type.
1567 -- Has_Inheritable_Invariants (Flag248)
1568 -- Present in all type entities. Set True in private types from which one
1569 -- or more Invariant'Class aspects will be inherited if a another type is
1570 -- derived from the type (i.e. those types which have an Invariant'Class
1571 -- aspect, or which inherit one or more Invariant'Class aspects). Also
1572 -- set in the corresponding full types. Note that it might be the full
1573 -- type which has inheritable invariants, and in this case the flag will
1574 -- also be set in the private type.
1576 -- Has_Machine_Radix_Clause (Flag83)
1577 -- Present in decimal types and subtypes, set if a Machine_Radix
1578 -- representation clause is present. This flag is used to detect
1579 -- the error of multiple machine radix clauses for a single type.
1581 -- Has_Master_Entity (Flag21)
1582 -- Present in entities that can appear in the scope stack (see spec
1583 -- of Sem). It is set if a task master entity (_master) has been
1584 -- declared and initialized in the corresponding scope.
1586 -- Has_Missing_Return (Flag142)
1587 -- Present in functions and generic functions. Set if there is one or
1588 -- more missing return statements in the function. This is used to
1589 -- control wrapping of the body in Exp_Ch6 to ensure that the program
1590 -- error exception is correctly raised in this case at runtime.
1592 -- Has_Nested_Block_With_Handler (Flag101)
1593 -- Present in scope entities. Set if there is a nested block within the
1594 -- scope that has an exception handler and the two scopes are in the
1595 -- same procedure. This is used by the backend for controlling certain
1596 -- optimizations to ensure that they are consistent with exceptions.
1597 -- See documentation in Gigi for further details.
1599 -- Has_Non_Standard_Rep (Flag75) [implementation base type only]
1600 -- Present in all type entities. Set when some representation clause
1601 -- or pragma causes the representation of the item to be significantly
1602 -- modified. In this category are changes of small or radix for a
1603 -- fixed-point type, change of component size for an array, and record
1604 -- or enumeration representation clauses, as well as packed pragmas.
1605 -- All other representation clauses (e.g. Size and Alignment clauses)
1606 -- are not considered to be significant since they do not affect
1607 -- stored bit patterns.
1609 -- Has_Object_Size_Clause (Flag172)
1610 -- Present in entities for types and subtypes. Set if an Object_Size
1611 -- clause has been processed for the type Used to prevent multiple
1612 -- Object_Size clauses for a given entity.
1614 -- Has_Per_Object_Constraint (Flag154)
1615 -- Present in E_Component entities, true if the subtype of the
1616 -- component has a per object constraint. Per object constraints result
1617 -- from the following situations:
1619 -- 1. N_Attribute_Reference - when the prefix is the enclosing type and
1620 -- the attribute is Access.
1621 -- 2. N_Discriminant_Association - when the expression uses the
1622 -- discriminant of the enclosing type.
1623 -- 3. N_Index_Or_Discriminant_Constraint - when at least one of the
1624 -- individual constraints is a per object constraint.
1625 -- 4. N_Range - when the lower or upper bound uses the discriminant of
1626 -- the enclosing type.
1627 -- 5. N_Range_Constraint - when the range expression uses the
1628 -- discriminant of the enclosing type.
1630 -- Has_Persistent_BSS (Flag188)
1631 -- Present in all entities. Set True for entities to which a valid
1632 -- pragma Persistent_BSS applies. Note that although the pragma is
1633 -- only meaningful for objects, we set it for all entities in a unit
1634 -- to which the pragma applies, as well as the unit entity itself, for
1635 -- convenience in propagating the flag to contained entities.
1637 -- Has_Postconditions (Flag240)
1638 -- Present in subprogram entities. Set if postconditions are active for
1639 -- the procedure, and a _postconditions procedure has been generated.
1641 -- Has_Pragma_Controlled (Flag27) [implementation base type only]
1642 -- Present in access type entities. It is set if a pragma Controlled
1643 -- applies to the access type.
1645 -- Has_Pragma_Elaborate_Body (Flag150)
1646 -- Present in all entities. Set in compilation unit entities if a
1647 -- pragma Elaborate_Body applies to the compilation unit.
1649 -- Has_Pragma_Inline (Flag157)
1650 -- Present in all entities. Set for functions and procedures for which a
1651 -- pragma Inline or Inline_Always applies to the subprogram. Note that
1652 -- this flag can be set even if Is_Inlined is not set. This happens for
1653 -- pragma Inline (if Inline_Active is False). In other words, the flag
1654 -- Has_Pragma_Inline represents the formal semantic status, and is used
1655 -- for checking semantic correctness. The flag Is_Inlined indicates
1656 -- whether inlining is actually active for the entity.
1658 -- Has_Pragma_Inline_Always (Flag230)
1659 -- Present in all entities. Set for functions and procedures for which a
1660 -- pragma Inline_Always applies. Note that if this flag is set, the flag
1661 -- Has_Pragma_Inline is also set.
1663 -- Has_Pragma_Ordered (Flag198) [implementation base type only]
1664 -- Present in entities for enumeration types. If set indicates that a
1665 -- valid pragma Ordered was given for the type. This flag is inherited
1666 -- by derived enumeration types. We don't need to distinguish the derived
1667 -- case since we allow multiple occurrences of this pragma anyway.
1669 -- Has_Pragma_Pack (Flag121) [implementation base type only]
1670 -- Present in array and record type entities. If set, indicates that a
1671 -- valid pragma Pack was given for the type. Note that this flag is not
1672 -- inherited by derived type. See also the Is_Packed flag.
1674 -- Has_Pragma_Pure (Flag203)
1675 -- Present in all entities. If set, indicates that a valid pragma Pure
1676 -- was given for the entity. In some cases, we need to test whether
1677 -- Is_Pure was explicitly set using this pragma.
1679 -- Has_Pragma_Preelab_Init (Flag221)
1680 -- Present in type and subtype entities. If set indicates that a valid
1681 -- pragma Preelaborable_Initialization applies to the type.
1683 -- Has_Pragma_Pure_Function (Flag179)
1684 -- Present in all entities. If set, indicates that a valid pragma
1685 -- Pure_Function was given for the entity. In some cases, we need to
1686 -- know that Is_Pure was explicitly set using this pragma. We also set
1687 -- this flag for some internal entities that we know should be treated
1688 -- as pure for optimization purposes.
1690 -- Has_Pragma_Thread_Local_Storage (Flag169)
1691 -- Present in all entities. If set, indicates that a valid pragma
1692 -- Thread_Local_Storage was given for the entity.
1694 -- Has_Pragma_Unmodified (Flag233)
1695 -- Present in all entities. Can only be set for variables (E_Variable,
1696 -- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified
1697 -- applies to the variable, indicating that no warning should be given
1698 -- if the entity is never modified. Note that clients should generally
1699 -- not test this flag directly, but instead use function Has_Unmodified.
1701 -- Has_Pragma_Unreferenced (Flag180)
1702 -- Present in all entities. Set if a valid pragma Unreferenced applies
1703 -- to the entity, indicating that no warning should be given if the
1704 -- entity has no references, but a warning should be given if it is
1705 -- in fact referenced. For private types, this flag is set in both the
1706 -- private entity and full entity if the pragma applies to either. Note
1707 -- that clients should generally not test this flag directly, but instead
1708 -- use function Has_Unreferenced.
1710 -- Has_Pragma_Unreferenced_Objects (Flag212)
1711 -- Present in type and subtype entities. Set if a valid pragma
1712 -- Unreferenced_Objects applies to the type, indicating that no warning
1713 -- should be given for objects of such a type for being unreferenced
1714 -- (but unlike the case with pragma Unreferenced, it is ok to reference
1715 -- such an object and no warning is generated.
1717 -- Has_Predicates (Flag250)
1718 -- Present in all entities. Set in type and subtype entities if a pragma
1719 -- Predicate or Predicate aspect applies to the type, or if it inherits a
1720 -- Predicate aspect from its parent or progenitor types. Also set in the
1721 -- predicate function entity, to distinguish it among entries in the
1722 -- Subprograms_For_Type.
1724 -- Has_Primitive_Operations (Flag120) [base type only]
1725 -- Present in all type entities. Set if at least one primitive operation
1726 -- is defined for the type.
1728 -- Has_Private_Ancestor (Flag151)
1729 -- Applies to type extensions. True if some ancestor is derived from a
1730 -- private type, making some components invisible and aggregates illegal.
1731 -- This flag is set at the point of derivation. The legality of the
1732 -- aggregate must be rechecked because it also depends on the visibility
1733 -- at the point the aggregate is resolved. See sem_aggr.adb.
1734 -- This is part of AI05-0115.
1736 -- Has_Private_Declaration (Flag155)
1737 -- Present in all entities. Returns True if it is the defining entity
1738 -- of a private type declaration or its corresponding full declaration.
1739 -- This flag is thus preserved when the full and the partial views are
1740 -- exchanged, to indicate if a full type declaration is a completion.
1741 -- Used for semantic checks in E.4(18) and elsewhere.
1743 -- Has_Qualified_Name (Flag161)
1744 -- Present in all entities. Set True if the name in the Chars field
1745 -- has been replaced by its qualified name, as used for debug output.
1746 -- See Exp_Dbug for a full description of qualification requirements.
1747 -- For some entities, the name is the fully qualified name, but there
1748 -- are exceptions. In particular, for local variables in procedures,
1749 -- we do not include the procedure itself or higher scopes. See also
1750 -- the flag Has_Fully_Qualified_Name, which is set if the name does
1751 -- indeed include the fully qualified name.
1753 -- Has_RACW (Flag214)
1754 -- Present in package spec entities. Set if the spec contains the
1755 -- declaration of a remote access-to-classwide type.
1757 -- Has_Record_Rep_Clause (Flag65) [implementation base type only]
1758 -- Present in record types. Set if a record representation clause has
1759 -- been given for this record type. Used to prevent more than one such
1760 -- clause for a given record type. Note that this is initially cleared
1761 -- for a derived type, even though the representation is inherited. See
1762 -- also the flag Has_Specified_Layout.
1764 -- Has_Recursive_Call (Flag143)
1765 -- Present in procedures. Set if a direct parameterless recursive call
1766 -- is detected while analyzing the body. Used to activate some error
1767 -- checks for infinite recursion.
1769 -- Has_Size_Clause (Flag29)
1770 -- Present in entities for types and objects. Set if a size clause is
1771 -- present for the entity. Used to prevent multiple Size clauses for a
1772 -- given entity. Note that it is always initially cleared for a derived
1773 -- type, even though the Size for such a type is inherited from a Size
1774 -- clause given for the parent type.
1776 -- Has_Small_Clause (Flag67)
1777 -- Present in ordinary fixed point types (but not subtypes). Indicates
1778 -- that a small clause has been given for the entity. Used to prevent
1779 -- multiple Small clauses for a given entity. Note that it is always
1780 -- initially cleared for a derived type, even though the Small for such
1781 -- a type is inherited from a Small clause given for the parent type.
1783 -- Has_Specified_Layout (Flag100) [implementation base type only]
1784 -- Present in all type entities. Set for a record type or subtype if
1785 -- the record layout has been specified by a record representation
1786 -- clause. Note that this differs from the flag Has_Record_Rep_Clause
1787 -- in that it is inherited by a derived type. Has_Record_Rep_Clause is
1788 -- used to indicate that the type is mentioned explicitly in a record
1789 -- representation clause, and thus is not inherited by a derived type.
1790 -- This flag is always False for non-record types.
1792 -- Has_Specified_Stream_Input (Flag190)
1793 -- Has_Specified_Stream_Output (Flag191)
1794 -- Has_Specified_Stream_Read (Flag192)
1795 -- Has_Specified_Stream_Write (Flag193)
1796 -- Present in all type and subtype entities. Set for a given view if the
1797 -- corresponding stream-oriented attribute has been defined by an
1798 -- attribute definition clause. When such a clause occurs, a TSS is set
1799 -- on the underlying full view; the flags are used to track visibility of
1800 -- the attribute definition clause for partial or incomplete views.
1802 -- Has_Static_Discriminants (Flag211)
1803 -- Present in record subtypes constrained by discriminant values. Set if
1804 -- all the discriminant values have static values, meaning that in the
1805 -- case of a variant record, the component list can be trimmed down to
1806 -- include only the components corresponding to these discriminants.
1808 -- Has_Storage_Size_Clause (Flag23) [implementation base type only]
1809 -- Present in task types and access types. It is set if a Storage_Size
1810 -- clause is present for the type. Used to prevent multiple clauses for
1811 -- one type. Note that this flag is initially cleared for a derived type
1812 -- even though the Storage_Size for such a type is inherited from a
1813 -- Storage_Size clause given for the parent type. Note that in the case
1814 -- of access types, this flag is present only in the root type, since a
1815 -- storage size clause cannot be given to a derived type.
1817 -- Has_Stream_Size_Clause (Flag184)
1818 -- Present in all entities. It is set for types which have a Stream_Size
1819 -- clause attribute. Used to prevent multiple Stream_Size clauses for a
1820 -- given entity, and also whether it is necessary to check for a stream
1823 -- Has_Subprogram_Descriptor (Flag93)
1824 -- This flag is set on entities for which zero-cost exception subprogram
1825 -- descriptors can be generated (subprograms and library level package
1826 -- declarations and bodies). It indicates that a subprogram descriptor
1827 -- has been generated, and is used to suppress generation of multiple
1828 -- descriptors (e.g. when instantiating generic bodies).
1830 -- Has_Task (Flag30) [base type only]
1831 -- Present in all type entities. Set on task types themselves, and also
1832 -- (recursively) on any composite type which has a component for which
1833 -- Has_Task is set. The meaning is that an allocator or declaration of
1834 -- such an object must create the required tasks. Note: the flag is not
1835 -- set on access types, even if they designate an object that Has_Task.
1837 -- Has_Thunks (Flag228)
1838 -- Applies to E_Constant entities marked Is_Tag. True for secondary tag
1839 -- referencing a dispatch table whose contents are pointers to thunks.
1841 -- Has_Unchecked_Union (Flag123) [base type only]
1842 -- Present in all type entities. Set on unchecked unions themselves
1843 -- and (recursively) on any composite type which has a component for
1844 -- which Has_Unchecked_Union is set. The meaning is that a comparison
1845 -- operation for the type is not permitted. Note that the flag is not
1846 -- set on access types, even if they designate an object that has
1847 -- the flag Has_Unchecked_Union set.
1849 -- Has_Unknown_Discriminants (Flag72)
1850 -- Present in all entities. Set for types with unknown discriminants.
1851 -- Types can have unknown discriminants either from their declaration or
1852 -- through type derivation. The use of this flag exactly meets the spec
1853 -- in RM 3.7(26). Note that all class-wide types are considered to have
1854 -- unknown discriminants. Note that both Has_Discriminants and
1855 -- Has_Unknown_Discriminants may be true for a type. Class-wide types and
1856 -- their subtypes have unknown discriminants and can have declared ones
1857 -- as well. Private types declared with unknown discriminants may have a
1858 -- full view that has explicit discriminants, and both flag will be set
1859 -- on the partial view, to insure that discriminants are properly
1860 -- inherited in certain contexts.
1862 -- Has_Up_Level_Access (Flag215)
1863 -- Present in E_Variable and E_Constant entities. Set if the entity
1864 -- is a local variable declared in a subprogram p and is accessed in
1865 -- a subprogram nested inside p. Currently this flag is only set when
1866 -- VM_Target /= No_VM, for efficiency, since only the .NET back-end
1867 -- makes use of it to generate proper code for up-level references.
1869 -- Has_Volatile_Components (Flag87) [implementation base type only]
1870 -- Present in all types and objects. Set only for an array type or array
1871 -- object if a valid pragma Volatile_Components or a valid pragma
1872 -- Atomic_Components applies to the type or object. Note that in the case
1873 -- of an object, this flag is only set on the object if there was an
1874 -- explicit pragma for the object. In other words, the proper test for
1875 -- whether an object has volatile components is to see if either the
1876 -- object or its base type has this flag set. Note that in the case of a
1877 -- type the pragma will be chained to the rep item chain of the first
1878 -- subtype in the usual manner.
1880 -- Has_Xref_Entry (Flag182)
1881 -- Present in all entities. Set if an entity has an entry in the Xref
1882 -- information generated in ali files. This is true for all source
1883 -- entities in the extended main source file. It is also true of entities
1884 -- in other packages that are referenced directly or indirectly from the
1885 -- main source file (indirect reference occurs when the main source file
1886 -- references an entity with a type reference. See package Lib.Xref for
1887 -- further details).
1889 -- Hiding_Loop_Variable (Node8)
1890 -- Present in variables. Set only if a variable of a discrete type is
1891 -- hidden by a loop variable in the same local scope, in which case
1892 -- the Hiding_Loop_Variable field of the hidden variable points to
1893 -- the E_Loop_Parameter entity doing the hiding. Used in processing
1894 -- warning messages if the hidden variable turns out to be unused
1895 -- or is referenced without being set.
1898 -- Present in all entities. Link for list of entities that have the
1899 -- same source name and that are declared in the same or enclosing
1900 -- scopes. Homonyms in the same scope are overloaded. Used for name
1901 -- resolution and for the generation of debugging information.
1903 -- Implementation_Base_Type (synthesized)
1904 -- Applies to all entities. For types, similar to Base_Type, but never
1905 -- returns a private type when applied to a non-private type. Instead in
1906 -- this case, it always returns the Underlying_Type of the base type, so
1907 -- that we still have a concrete type. For entities other than types,
1908 -- returns the entity unchanged.
1910 -- Interface_Alias (Node25)
1911 -- Present in subprograms that cover a primitive operation of an abstract
1912 -- interface type. Can be set only if the Is_Hidden flag is also set,
1913 -- since such entities are always hidden. Points to its associated
1914 -- interface subprogram. It is used to register the subprogram in
1915 -- secondary dispatch table of the interface (Ada 2005: AI-251).
1917 -- Interfaces (Elist25)
1918 -- Present in record types and subtypes. List of abstract interfaces
1919 -- implemented by a tagged type that are not already implemented by the
1920 -- ancestors (Ada 2005: AI-251).
1922 -- In_Package_Body (Flag48)
1923 -- Present in package entities. Set on the entity that denotes the
1924 -- package (the defining occurrence of the package declaration) while
1925 -- analyzing and expanding the package body. Reset on completion of
1926 -- analysis/expansion.
1928 -- In_Private_Part (Flag45)
1929 -- Present in all entities. Can be set only in package entities and
1930 -- objects. For package entities, this flag is set to indicate that the
1931 -- private part of the package is being analyzed. The flag is reset at
1932 -- the end of the package declaration. For objects it indicates that the
1933 -- declaration of the object occurs in the private part of a package.
1935 -- Inner_Instances (Elist23)
1936 -- Present in generic units. Contains element list of units that are
1937 -- instantiated within the given generic. Used to diagnose circular
1940 -- Interface_Name (Node21)
1941 -- Present in constants, variables, exceptions, functions, procedures,
1942 -- packages, components (JGNAT only), discriminants (JGNAT only), and
1943 -- access to subprograms (JGNAT only). Set to Empty unless an export,
1944 -- import, or interface name pragma has explicitly specified an external
1945 -- name, in which case it references an N_String_Literal node for the
1946 -- specified external name. In the case of exceptions, the field is set
1947 -- by Import_Exception/Export_Exception (which can be used in OpenVMS
1948 -- versions only). Note that if this field is Empty, and Is_Imported
1949 -- or Is_Exported is set, then the default interface name is the name
1950 -- of the entity, cased in a manner that is appropriate to the system
1951 -- in use. Note that Interface_Name is ignored if an address clause
1952 -- is present (since it is meaningless in this case).
1954 -- An additional special case usage of this field is in JGNAT for
1955 -- E_Component and E_Discriminant. JGNAT allows these entities to be
1956 -- imported by specifying pragma Import within a component's containing
1957 -- record definition. This supports interfacing to object fields defined
1958 -- within Java classes, and such pragmas are generated by the jvm2ada
1959 -- binding generator tool whenever it processes classes with public
1960 -- object fields. A pragma Import for a component can define the
1961 -- External_Name of the imported Java field (which is generally needed,
1962 -- because Java names are case sensitive).
1964 -- Invariant_Procedure (synthesized)
1965 -- Present in types and subtypes. Set for private types if one or more
1966 -- Invariant, or Invariant'Class, or inherited Invariant'Class aspects
1967 -- apply to the type. Points to the entity for a procedure which checks
1968 -- the invariant. This invariant procedure takes a single argument of the
1969 -- given type, and returns if the invariant holds, or raises exception
1970 -- Assertion_Error with an appropriate message if it does not hold. This
1971 -- attribute is present but always empty for private subtypes. This
1972 -- attribute is also set for the corresponding full type.
1974 -- Note: the reason this is marked as a synthesized attribute is that the
1975 -- way this is stored is as an element of the Subprograms_For_Type field.
1978 -- Present in packages and types. Set when analyzing a use clause for
1979 -- the corresponding entity. Reset at end of corresponding declarative
1980 -- part. The flag on a type is also used to determine the visibility of
1981 -- the primitive operators of the type.
1983 -- Is_Abstract_Subprogram (Flag19)
1984 -- Present in all subprograms and entries. Set for abstract subprograms.
1985 -- Always False for enumeration literals and entries. See also
1986 -- Requires_Overriding.
1988 -- Is_Abstract_Type (Flag146)
1989 -- Present in all types. Set for abstract types.
1991 -- Is_Access_Constant (Flag69)

2000 -- Applies to all entities, true for access types and subtypes
2002 -- Is_Ada_2005_Only (Flag185)
2003 -- Present in all entities, true if a valid pragma Ada_05 or Ada_2005
2004 -- applies to the entity which specifically names the entity, indicating
2005 -- that the entity is Ada 2005 only. Note that this flag is not set if
2006 -- the entity is part of a unit compiled with the normal no-argument form
2007 -- of pragma Ada_05 or Ada_2005.
2009 -- Is_Ada_2012_Only (Flag199)
2010 -- Present in all entities, true if a valid pragma Ada_12 or Ada_2012
2011 -- applies to the entity which specifically names the entity, indicating
2012 -- that the entity is Ada 2012 only. Note that this flag is not set if

2014 -- of pragma Ada_12 or Ada_2012.
2016 -- Is_Aliased (Flag15)
2017 -- Present in all entities. Set for objects and types whose declarations
2018 -- carry the keyword aliased, and on record components that have the
2019 -- keyword. For Ada 2012, also applies to formal parameters.
2021 -- Is_AST_Entry (Flag132)
2022 -- Present in entry entities. Set if a valid pragma AST_Entry applies
2023 -- to the entry. This flag can only be set in OpenVMS versions of GNAT.
2024 -- Note: we also allow the flag to appear in entry families, but given
2025 -- the current implementation of the pragma AST_Entry, this flag will
2026 -- always be False in entry families.
2028 -- Is_Atomic (Flag85)
2029 -- Present in all type entities, and also in constants, components and
2030 -- variables. Set if a pragma Atomic or Shared applies to the entity.

2032 -- both the partial view and the full view.
2034 -- Is_Array_Type (synthesized)
2035 -- Applies to all entities, true for array types and subtypes
2037 -- Is_Asynchronous (Flag81)
2038 -- Present in all type entities and in procedure entities. Set

2041 -- Is_Base_Type (synthesized)
2042 -- Applies to type and subtype entities. True if entity is a base type
2044 -- Is_Bit_Packed_Array (Flag122) [implementation base type only]
2045 -- Present in all entities. This flag is set for a packed array type that
2046 -- is bit packed (i.e. the component size is known by the front end and
2047 -- is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed is always set
2048 -- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be
2049 -- set without Is_Bit_Packed_Array for the case of an array having one or
2050 -- more index types that are enumeration types with non-standard
2051 -- enumeration representations.
2053 -- Is_Boolean_Type (synthesized)
2054 -- Applies to all entities, true for boolean types and subtypes,
2055 -- i.e. Standard.Boolean and all types ultimately derived from it.
2057 -- Is_Called (Flag102)
2058 -- Present in subprograms. Returns true if the subprogram is called

2071 -- Applies to all entities, true for class wide types and subtypes
2073 -- Is_Class_Wide_Equivalent_Type (Flag35)

2076 -- some class-wide subtype entity references this record type.
2078 -- Is_Compilation_Unit (Flag149)
2079 -- Present in all entities. Set if the entity is a package or subprogram
2080 -- entity for a compilation unit other than a subunit (since we treat
2081 -- subunits as part of the same compilation operation as the ultimate
2082 -- parent, we do not consider them to be separate units for this flag).
2084 -- Is_Completely_Hidden (Flag103)
2085 -- Present in all entities. This flag can be set only for E_Discriminant
2086 -- entities. This flag can be set only for girder discriminants of
2087 -- untagged types. When set, the entity is a girder discriminant of a
2088 -- derived untagged type which is not directly visible in the derived
2089 -- type because the derived type or one of its ancestors have renamed the
2090 -- discriminants in the root type. Note: there are girder discriminants
2091 -- which are not Completely_Hidden (e.g. discriminants of a root type).
2093 -- Is_Composite_Type (synthesized)
2094 -- Applies to all entities, true for all composite types and

2098 -- Is_Concurrent_Record_Type (Flag20)
2099 -- Present in record types and subtypes. Set if the type was created
2100 -- by the expander to represent a task or protected type. For every
2101 -- concurrent type, such as record type is constructed, and task and
2102 -- protected objects are instances of this record type at runtime
2103 -- (Gigi will replace declarations of the concurrent type using the
2104 -- declarations of the corresponding record type). See package Exp_Ch9
2105 -- for further details.
2107 -- Is_Concurrent_Type (synthesized)
2108 -- Applies to all entities, true for task types and subtypes and for
2109 -- protected types and subtypes.

2112 -- Applies to all entities, true for E_Constant, E_Loop_Parameter, and
2113 -- E_In_Parameter entities.
2115 -- Is_Constrained (Flag12)
2116 -- Present in types or subtypes which may have index, discriminant
2117 -- or range constraint (i.e. array types and subtypes, record types
2118 -- and subtypes, string types and subtypes, and all numeric types).
2119 -- Set if the type or subtype is constrained.
2121 -- Is_Constr_Subt_For_U_Nominal (Flag80)
2122 -- Present in all types and subtypes. Set true only for the constructed
2123 -- subtype of an object whose nominal subtype is unconstrained. Note
2124 -- that the constructed subtype itself will be constrained.
2126 -- Is_Constr_Subt_For_UN_Aliased (Flag141)
2127 -- Present in all types and subtypes. This flag can be set only if
2128 -- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in
2129 -- addition the object concerned is aliased. This flag is used by
2130 -- Gigi to determine whether a template must be constructed.
2132 -- Is_Constructor (Flag76)
2133 -- Present in function and procedure entities. Set if a pragma
2134 -- CPP_Constructor applies to the subprogram.
2136 -- Is_Controlled (Flag42) [base type only]
2137 -- Present in all type entities. Indicates that the type is controlled,
2138 -- i.e. is either a descendant of Ada.Finalization.Controlled or of
2139 -- Ada.Finalization.Limited_Controlled.
2141 -- Is_Controlling_Formal (Flag97)
2142 -- Present in all Formal_Kind entities. Marks the controlling parameters
2143 -- of dispatching operations.
2145 -- Is_CPP_Class (Flag74)
2146 -- Present in all type entities, set only for tagged types to which a
2147 -- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied.
2149 -- Is_Decimal_Fixed_Point_Type (synthesized)
2150 -- Applies to all type entities, true for decimal fixed point
2151 -- types and subtypes.
2153 -- Is_Descendent_Of_Address (Flag223)
2154 -- Present in all type and subtype entities. Indicates that a type is an
2155 -- address type that is visibly a numeric type. Used for semantic checks
2156 -- on VMS to remove ambiguities in universal integer expressions that may
2157 -- have an address interpretation
2159 -- Is_Discrete_Type (synthesized)
2160 -- Applies to all entities, true for all discrete types and subtypes
2162 -- Is_Discrete_Or_Fixed_Point_Type (synthesized)

2167 -- Present in all entities. Set only in E_Function entities that Layout
2168 -- creates to compute discriminant-dependent dynamic size/offset values.
2170 -- Is_Discriminal (synthesized)
2171 -- Applies to all entities, true for renamings of discriminants. Such
2172 -- entities appear as constants or in parameters.
2174 -- Is_Dispatch_Table_Entity (Flag234)
2175 -- Applies to all entities. Set to indicate to the backend that this
2176 -- entity is associated with a dispatch table.
2178 -- Is_Dispatching_Operation (Flag6)
2179 -- Present in all entities. Set true for procedures, functions,
2180 -- generic procedures and generic functions if the corresponding
2181 -- operation is dispatching.
2183 -- Is_Dynamic_Scope (synthesized)
2184 -- Applies to all Entities. Returns True if the entity is a dynamic
2185 -- scope (i.e. a block, subprogram, task_type, entry
2186 -- or extended return statement).
2188 -- Is_Elementary_Type (synthesized)
2189 -- Applies to all entities, true for all elementary types and
2190 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
2191 -- not both) is true of any type.
2193 -- Is_Eliminated (Flag124)
2194 -- Present in type entities, subprogram entities, and object entities.
2195 -- Indicates that the corresponding entity has been eliminated by use
2196 -- of pragma Eliminate. Also used to mark subprogram entities whose
2197 -- declaration and body are within unreachable code that is removed.
2199 -- Is_Enumeration_Type (synthesized)
2200 -- Present in all entities, true for enumeration types and subtypes
2202 -- Is_Entry (synthesized)
2203 -- Applies to all entities, True only for entry and entry family
2204 -- entities and False for all other entity kinds.
2206 -- Is_Entry_Formal (Flag52)
2207 -- Present in all entities. Set only for entry formals (which can
2208 -- only be in, in-out or out parameters). This flag is used to speed
2209 -- up the test for the need to replace references in Exp_Ch2.
2211 -- Is_Exported (Flag99)
2212 -- Present in all entities. Set if the entity is exported. For now we
2213 -- only allow the export of constants, exceptions, functions, procedures
2214 -- and variables, but that may well change later on. Exceptions can only
2215 -- be exported in the OpenVMS and Java VM implementations of GNAT.
2217 -- Is_Finalizer (synthesized)
2218 -- Applies to all entities, true for procedures containing finalization
2219 -- code to process local or library level objects.
2221 -- Is_First_Subtype (Flag70)
2222 -- Present in all entities. True for first subtypes (RM 3.2.1(6)),
2223 -- i.e. the entity in the type declaration that introduced the type.
2224 -- This may be the base type itself (e.g. for record declarations and
2225 -- enumeration type declarations), or it may be the first subtype of
2226 -- an anonymous base type (e.g. for integer type declarations or
2227 -- constrained array declarations).
2229 -- Is_Fixed_Point_Type (synthesized)
2230 -- Applies to all entities, true for decimal and ordinary fixed

2243 -- Present in all entities. Set for generic formal subprograms.
2245 -- Is_For_Access_Subtype (Flag118)
2246 -- Present in E_Private_Subtype and E_Record_Subtype entities. Means the
2247 -- sole purpose of the type is to be designated by an Access_Subtype and
2248 -- hence should not be expanded into components because the type may not
2249 -- have been found or frozen yet.
2251 -- Is_Frozen (Flag4)
2252 -- Present in all type and subtype entities. Set if type or subtype has
2255 -- Is_Generic_Actual_Type (Flag94)
2256 -- Present in all type and subtype entities. Set in the subtype
2257 -- declaration that renames the generic formal as a subtype of the
2258 -- actual. Guarantees that the subtype is not static within the instance.
2260 -- Is_Generic_Instance (Flag130)
2261 -- Present in all entities. Set to indicate that the entity is an
2262 -- instance of a generic unit, or a formal package (which is an instance
2263 -- of the template).
2265 -- Is_Generic_Subprogram (synthesized)
2266 -- Applies to all entities. Yields True for a generic subprogram
2267 -- (generic function, generic subprogram), False for all other entities.
2269 -- Is_Generic_Type (Flag13)
2270 -- Present in all entities. Set for types which are generic formal types.
2271 -- Such types have an Ekind that corresponds to their classification, so
2272 -- the Ekind cannot be used to identify generic types.
2274 -- Is_Generic_Unit (synthesized)
2275 -- Applies to all entities. Yields True for a generic unit (generic
2276 -- package, generic function, generic procedure), and False for all
2279 -- Is_Hidden (Flag57)
2280 -- Present in all entities. Set true for all entities declared in the
2281 -- private part or body of a package. Also marks generic formals of a
2282 -- formal package declared without a box. For library level entities,
2283 -- this flag is set if the entity is not publicly visible. This flag
2284 -- is reset when compiling the body of the package where the entity
2285 -- is declared, when compiling the private part or body of a public
2286 -- child unit, and when compiling a private child unit (see Install_
2287 -- Private_Declaration in sem_ch7).
2289 -- Is_Hidden_Open_Scope (Flag171)
2290 -- Present in all entities. Set true for a scope that contains the
2291 -- instantiation of a child unit, and whose entities are not visible
2292 -- during analysis of the instance.
2294 -- Is_Immediately_Visible (Flag7)
2295 -- Present in all entities. Set if entity is immediately visible, i.e.
2296 -- is defined in some currently open scope (RM 8.3(4)).
2298 -- Is_Implementation_Defined (Flag254)
2299 -- Present in all entities. Set if a pragma Implementation_Defined is
2300 -- applied to the pragma. Used to mark all implementation defined
2301 -- identifiers in standard library packages, and to implement the
2302 -- restriction No_Implementation_Identifiers.
2304 -- Is_Imported (Flag24)
2305 -- Present in all entities. Set if the entity is imported. For now we
2306 -- only allow the import of exceptions, functions, procedures, packages.
2307 -- and variables. Exceptions can only be imported in the OpenVMS and
2308 -- Java VM implementations of GNAT. Packages and types can only be
2309 -- imported in the Java VM implementation.
2311 -- Is_Incomplete_Or_Private_Type (synthesized)
2312 -- Applies to all entities, true for private and incomplete types
2314 -- Is_Incomplete_Type (synthesized)
2315 -- Applies to all entities, true for incomplete types and subtypes
2317 -- Is_Inlined (Flag11)
2318 -- Present in all entities. Set for functions and procedures which are
2319 -- to be inlined. For subprograms created during expansion, this flag
2320 -- may be set directly by the expander to request inlining. Also set
2321 -- for packages that contain inlined subprograms, whose bodies must be
2322 -- be compiled. Is_Inlined is also set on generic subprograms and is
2323 -- inherited by their instances. It is also set on the body entities
2324 -- of inlined subprograms. See also Has_Pragma_Inline.
2326 -- Is_Instantiated (Flag126)
2327 -- Present in generic packages and generic subprograms. Set if the unit
2328 -- is instantiated from somewhere in the extended main source unit. This
2329 -- flag is used to control warnings about the unit being uninstantiated.
2330 -- Also set in a package that is used as an actual for a generic package
2331 -- formal in an instantiation. Also set on a parent instance, in the
2332 -- instantiation of a child, which is implicitly declared in the parent.
2334 -- Is_Integer_Type (synthesized)
2335 -- Applies to all entities, true for integer types and subtypes
2337 -- Is_Interface (Flag186)
2338 -- Present in record types and subtypes. Set to indicate that the current
2339 -- entity corresponds with an abstract interface. Because abstract
2340 -- interfaces are conceptually a special kind of abstract tagged types
2341 -- we represent them by means of tagged record types and subtypes
2342 -- marked with this attribute. This allows us to reuse most of the
2343 -- compiler support for abstract tagged types to implement interfaces
2344 -- (Ada 2005: AI-251).
2346 -- Is_Internal (Flag17)
2347 -- Present in all entities. Set to indicate an entity created during
2348 -- semantic processing (e.g. an implicit type, or a temporary). The
2349 -- current uses of this flag are:
2351 -- 1) Internal entities (such as temporaries generated for the result
2352 -- of an inlined function call or dummy variables generated for the
2353 -- debugger). Set to indicate that they need not be initialized, even
2354 -- when scalars are initialized or normalized;
2356 -- 2) Predefined primitives of tagged types. Set to mark that they
2357 -- have specific properties: first they are primitives even if they
2358 -- are not defined in the type scope (the freezing point is not
2359 -- necessarily in the same scope), and second the predefined equality
2360 -- can be overridden by a user-defined equality, no body will be
2361 -- generated in this case.
2363 -- 3) Object declarations generated by the expander that are implicitly
2364 -- imported or exported so that they can be marked in Sprint output.
2366 -- 4) Internal entities in the list of primitives of tagged types that
2367 -- are used to handle secondary dispatch tables. These entities have
2368 -- also the attribute Interface_Alias.
2370 -- Is_Interrupt_Handler (Flag89)
2371 -- Present in procedures. Set if a pragma Interrupt_Handler applies
2372 -- to the procedure. The procedure must be parameterless, and on all
2373 -- targets except AAMP it must be a protected procedure.
2375 -- Is_Intrinsic_Subprogram (Flag64)
2376 -- Present in functions and procedures. It is set if a valid pragma
2377 -- Interface or Import is present for this subprogram specifying pragma
2378 -- Intrinsic. Valid means that the name and profile of the subprogram
2379 -- match the requirements of one of the recognized intrinsic subprograms
2380 -- (see package Sem_Intr for details). Note: the value of Convention for
2381 -- such an entity will be set to Convention_Intrinsic, but it is the
2382 -- setting of Is_Intrinsic_Subprogram, NOT simply having convention set
2383 -- to intrinsic, which causes intrinsic code to be generated.
2385 -- Is_Itype (Flag91)
2386 -- Present in all entities. Set to indicate that a type is an Itype,
2387 -- which means that the declaration for the type does not appear
2388 -- explicitly in the tree. Instead gigi will elaborate the type when it
2389 -- is first used. Has_Delayed_Freeze can be set for Itypes, and the
2390 -- meaning is that the first use (the one which causes the type to be
2391 -- defined) will be the freeze node. Note that an important restriction
2392 -- on Itypes is that the first use of such a type (the one that causes it
2393 -- to be defined) must be in the same scope as the type.
2395 -- Is_Known_Non_Null (Flag37)
2396 -- Present in all entities. Relevant (and can be set True) only for
2397 -- objects of an access type. It is set if the object is currently
2398 -- known to have a non-null value (meaning that no access checks
2399 -- are needed). The indication can for example come from assignment
2400 -- of an access parameter or an allocator whose value is known non-null.
2402 -- Note: this flag is set according to the sequential flow of the
2403 -- program, watching the current value of the variable. However,
2404 -- this processing can miss cases of changing the value of an aliased
2405 -- or constant object, so even if this flag is set, it should not
2406 -- be believed if the variable is aliased or volatile. It would
2407 -- be a little neater to avoid the flag being set in the first
2408 -- place in such cases, but that's trickier, and there is only
2409 -- one place that tests the value anyway.
2411 -- The flag is dynamically set and reset as semantic analysis and
2412 -- expansion proceeds. Its value is meaningless once the tree is
2413 -- fully constructed, since it simply indicates the last state.
2414 -- Thus this flag has no meaning to the back end.
2416 -- Is_Known_Null (Flag204)
2417 -- Present in all entities. Relevant (and can be set True) only for
2418 -- objects of an access type. It is set if the object is currently known
2419 -- to have a null value (meaning that a dereference will surely raise
2420 -- constraint error exception). The indication can come from an
2421 -- assignment or object declaration.
2423 -- The comments above about sequential flow and aliased and volatile for
2424 -- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag.
2426 -- Is_Known_Valid (Flag170)
2427 -- Present in all entities. Relevant for types (and subtype) and
2428 -- for objects (and enumeration literals) of a discrete type.
2430 -- The purpose of this flag is to implement the requirement stated
2431 -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
2432 -- values may not cause programs to become erroneous. See the function
2433 -- Checks.Expr_Known_Valid for further details. Note that the setting
2434 -- is conservative, in the sense that if the flag is set, it must be
2435 -- right. If the flag is not set, nothing is known about the validity.
2437 -- For enumeration literals, the flag is always set, since clearly
2438 -- an enumeration literal represents a valid value. Range checks
2439 -- where necessary will ensure that this valid value is appropriate.
2441 -- For objects, the flag indicates the state of knowledge about the
2442 -- current value of the object. This may be modified during expansion,
2443 -- and thus the final value is not relevant to gigi.
2445 -- For types and subtypes, the flag is set if all possible bit patterns
2446 -- of length Object_Size (i.e. Esize of the type) represent valid values
2447 -- of the type. In general for such tytpes, all values are valid, the
2448 -- only exception being the case where an object of the type has an
2449 -- explicit size that is greater than Object_Size.
2451 -- For non-discrete objects, the setting of the Is_Known_Valid flag is
2452 -- not defined, and is not relevant, since the considerations of the
2453 -- requirement in (RM 13.9.1(9-11)) do not apply.
2455 -- The flag is dynamically set and reset as semantic analysis and
2456 -- expansion proceeds. Its value is meaningless once the tree is
2457 -- fully constructed, since it simply indicates the last state.
2458 -- Thus this flag has no meaning to the back end.
2460 -- Is_Limited_Composite (Flag106)
2461 -- Present in all entities. Set for composite types that have a limited
2462 -- component. Used to enforce the rule that operations on the composite
2463 -- type that depend on the full view of the component do not become
2464 -- visible until the immediate scope of the composite type itself
2467 -- Is_Limited_Interface (Flag197)
2468 -- Present in record types and subtypes. True for interface types, if
2469 -- interface is declared limited, task, protected, or synchronized, or
2470 -- is derived from a limited interface.
2472 -- Is_Limited_Record (Flag25)
2473 -- Present in all entities. Set to true for record (sub)types if the
2474 -- record is declared to be limited. Note that this flag is not set
2475 -- simply because some components of the record are limited.
2477 -- Is_Local_Anonymous_Access (Flag194)
2478 -- Present in access types. Set for an anonymous access type to indicate
2479 -- that the type is created for a record component with an access
2480 -- definition, an array component, or (pre-Ada 2012) a standalone object.
2481 -- Such anonymous types have an accessibility level equal to that of the
2482 -- declaration in which they appear, unlike the anonymous access types
2483 -- that are created for access parameters, access discriminants, and
2484 -- (as of Ada 2012) stand-alone objects.
2486 -- Is_Machine_Code_Subprogram (Flag137)
2487 -- Present in subprogram entities. Set to indicate that the subprogram
2488 -- is a machine code subprogram (i.e. its body includes at least one
2489 -- code statement). Also indicates that all necessary semantic checks
2490 -- as required by RM 13.8(3) have been performed.
2492 -- Is_Modular_Integer_Type (synthesized)
2493 -- Applies to all entities. True if entity is a modular integer type
2495 -- Is_Non_Static_Subtype (Flag109)
2496 -- Present in all type and subtype entities. It is set in some (but not
2497 -- all) cases in which a subtype is known to be non-static. Before this
2498 -- flag was added, the computation of whether a subtype was static was
2499 -- entirely synthesized, by looking at the bounds, and the immediate
2500 -- subtype parent. However, this method does not work for some Itypes
2501 -- that have no parent set (and the only way to find the immediate
2502 -- subtype parent is to go through the tree). For now, this flay is set
2503 -- conservatively, i.e. if it is set then for sure the subtype is non-
2504 -- static, but if it is not set, then the type may or may not be static.
2505 -- Thus the test for a static subtype is that this flag is clear AND that
2506 -- the bounds are static AND that the parent subtype (if available to be
2507 -- tested) is static. Eventually we should make sure this flag is always
2508 -- set right, at which point, these comments can be removed, and the
2509 -- tests for static subtypes greatly simplified.
2511 -- Is_Null_Init_Proc (Flag178)
2512 -- Present in procedure entities. Set for generated init proc procedures
2513 -- (used to initialize composite types), if the code for the procedure
2514 -- is null (i.e. is a return and nothing else). Such null initialization
2515 -- procedures are generated in case some client is compiled using the
2516 -- Initialize_Scalars pragma, generating a call to this null procedure,
2517 -- but there is no need to call such procedures within a compilation
2518 -- unit, and this flag is used to suppress such calls.
2520 -- Is_Numeric_Type (synthesized)
2521 -- Applies to all entities, true for all numeric types and subtypes
2522 -- (integer, fixed, float).
2524 -- Is_Object (synthesized)
2525 -- Applies to all entities, true for entities representing objects,
2526 -- including generic formal parameters.
2528 -- Is_Obsolescent (Flag153)
2529 -- Present in all entities. Set for any entity for which a valid pragma
2530 -- Obsolescent applies.
2532 -- Is_Only_Out_Parameter (Flag226)
2533 -- Present in formal parameter entities. Set if this parameter is the
2534 -- only OUT parameter for this formal part. If there is more than one
2535 -- out parameter, or if there is some other IN OUT parameter then this
2536 -- flag is not set in any of them. Used in generation of warnings.
2538 -- Is_Optional_Parameter (Flag134)
2539 -- Present in parameter entities. Set if the parameter is specified as
2540 -- optional by use of a First_Optional_Parameter argument to one of the
2541 -- extended Import pragmas. Can only be set for OpenVMS versions of GNAT.
2543 -- Is_Ordinary_Fixed_Point_Type (synthesized)
2544 -- Applies to all entities, true for ordinary fixed point types and
2547 -- Is_Package_Or_Generic_Package (synthesized)
2548 -- Applies to all entities. True for packages and generic packages.
2549 -- False for all other entities.
2551 -- Is_Package_Body_Entity (Flag160)
2552 -- Present in all entities. Set for entities defined at the top level
2553 -- of a package body. Used to control externally generated names.
2555 -- Is_Packed (Flag51) [implementation base type only]
2556 -- Present in all type entities. This flag is set only for record and
2557 -- array types which have a packed representation. There are three
2558 -- cases which cause packing:
2560 -- 1. Explicit use of pragma Pack for an array of package components
2561 -- 2. Explicit use of pragma Pack to pack a record
2562 -- 4. Setting Component_Size of an array to a bit-packable value
2563 -- 3. Indexing an array with a non-standard enumeration type.
2565 -- For records, Is_Packed is always set if Has_Pragma_Pack is set,
2566 -- and can also be set on its own in a derived type which inherited
2567 -- its packed status.
2569 -- For arrays, Is_Packed is set if an array is bit packed (i.e. the
2570 -- component size is known at compile time and is 1-7, 9-15 or 17-31),
2571 -- or if the array has one or more index types that are enumeration
2572 -- types with non-standard representations (in GNAT, we store such
2573 -- arrays compactly, using the Pos of the enumeration type value).
2575 -- As for the case of records, Is_Packed can be set on its own for a
2576 -- derived type, with the same dual before/after freeze meaning.
2577 -- Is_Packed can also be set as the result of an explicit component
2578 -- size clause that specifies an appropriate component size.
2580 -- In the bit packed array case, Is_Bit_Packed_Array will be set in
2581 -- the bit packed case once the array type is frozen.
2583 -- Before an array type is frozen, Is_Packed will always be set if
2584 -- Has_Pragma_Pack is set. Before the freeze point, it is not possible
2585 -- to know the component size, since the component type is not frozen
2586 -- until the array type is frozen. Thus Is_Packed for an array type
2587 -- before it is frozen means that packed is required. Then if it turns
2588 -- out that the component size is not suitable for bit packing, the
2589 -- Is_Packed flag gets turned off.
2591 -- Is_Packed_Array_Type (Flag138)
2592 -- Present in all entities. This flag is set on the entity for the type
2593 -- used to implement a packed array (either a modular type, or a subtype
2594 -- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
2595 -- if the type appears in the Packed_Array_Type field of some other type
2596 -- entity. It is used by Gigi to activate the special processing for such
2597 -- types (unchecked conversions that would not otherwise be allowed are
2598 -- allowed for such types). If the Is_Packed_Array_Type flag is set in
2599 -- an entity, then the Original_Array_Type field of this entity points
2600 -- to the original array type for which this is the packed array type.
2602 -- Is_Potentially_Use_Visible (Flag9)
2603 -- Present in all entities. Set if entity is potentially use visible,
2604 -- i.e. it is defined in a package that appears in a currently active
2605 -- use clause (RM 8.4(8)). Note that potentially use visible entities
2606 -- are not necessarily use visible (RM 8.4(9-11)).
2608 -- Is_Preelaborated (Flag59)
2609 -- Present in all entities, set in E_Package and E_Generic_Package
2610 -- entities to which a pragma Preelaborate is applied, and also in
2611 -- all entities within such packages. Note that the fact that this
2612 -- flag is set does not necesarily mean that no elaboration code is
2613 -- generated for the package.
2615 -- Is_Primitive (Flag218)
2616 -- Present in overloadable entities and in generic subprograms. Set to
2617 -- indicate that this is a primitive operation of some type, which may
2618 -- be a tagged type or a non-tagged type. Used to verify overriding
2619 -- indicators in bodies.
2621 -- Is_Primitive_Wrapper (Flag195)
2622 -- Present in functions and procedures created by the expander to serve
2623 -- as an indirection mechanism to overriding primitives of concurrent
2624 -- types, entries and protected procedures.
2626 -- Is_Prival (synthesized)
2627 -- Applies to all entities, true for renamings of private protected
2628 -- components. Such entities appear as constants or variables.
2630 -- Is_Private_Composite (Flag107)
2631 -- Present in composite types that have a private component. Used to
2632 -- enforce the rule that operations on the composite type that depend
2633 -- on the full view of the component, do not become visible until the
2634 -- immediate scope of the composite type itself (7.3.1 (5)). Both this
2635 -- flag and Is_Limited_Composite are needed.
2637 -- Is_Private_Descendant (Flag53)
2638 -- Present in entities that can represent library units (packages,
2639 -- functions, procedures). Set if the library unit is itself a private
2640 -- child unit, or if it is the descendent of a private child unit.
2642 -- Is_Private_Primitive (Flag245)
2643 -- Present in subprograms. Set if the operation is a primitive of a
2644 -- tagged type (procedure or function dispatching on result) whose
2645 -- full view has not been seen. Used in particular for primitive
2646 -- subprograms of a synchronized type declared between the two views
2647 -- of the type, so that the wrapper built for such a subprogram can
2648 -- be given the proper signature.
2650 -- Is_Private_Type (synthesized)
2651 -- Applies to all entities, true for private types and subtypes,
2652 -- as well as for record with private types as subtypes
2654 -- Is_Processed_Transient (Flag252)
2655 -- Present in entities of variables and constants. Set when a transient
2656 -- object needs to be finalized and it has already been processed by the
2657 -- transient scope machinery. This flag signals the general finalization
2658 -- mechanism to ignore the transient object.
2660 -- Is_Protected_Component (synthesized)
2661 -- Applicable to all entities, true if the entity denotes a private
2662 -- component of a protected type.
2664 -- Is_Protected_Interface (synthesized)
2665 -- Present in types that are interfaces. True if interface is declared
2666 -- protected, or is derived from protected interfaces.
2668 -- Is_Protected_Type (synthesized)
2669 -- Applies to all entities, true for protected types and subtypes
2671 -- Is_Public (Flag10)
2672 -- Present in all entities. Set to indicate that an entity defined in
2673 -- one compilation unit can be referenced from other compilation units.
2674 -- If this reference causes a reference in the generated variable, for
2675 -- example in the case of a variable name, then Gigi will generate an
2676 -- appropriate external name for use by the linker.
2678 -- Is_Protected_Record_Type (synthesized)
2679 -- Applies to all entities, true if Is_Concurrent_Record_Type
2680 -- Corresponding_Concurrent_Type is a protected type.
2683 -- Present in all entities. Set in all entities of a unit to which a
2684 -- pragma Pure is applied, and also set for the entity of the unit
2685 -- itself. In addition, this flag may be set for any other functions
2686 -- or procedures that are known to be side effect free, so in the case
2687 -- of subprograms, the Is_Pure flag may be used by the optimizer to
2688 -- imply that it can assume freedom from side effects (other than those
2689 -- resulting from assignment to out parameters, or to objects designated
2690 -- by access parameters).
2692 -- Is_Pure_Unit_Access_Type (Flag189)
2693 -- Present in access type and subtype entities. Set if the type or
2694 -- subtype appears in a pure unit. Used to give an error message at
2695 -- freeze time if the access type has a storage pool.
2697 -- Is_RACW_Stub_Type (Flag244)
2698 -- Present in all types, true for the stub types generated for remote
2699 -- access-to-class-wide types.
2701 -- Is_Raised (Flag224)
2702 -- Present in exception entities. Set if the entity is referenced by a
2703 -- a raise statement.
2705 -- Is_Real_Type (synthesized)
2706 -- Applies to all entities, true for real types and subtypes
2708 -- Is_Record_Type (synthesized)
2709 -- Applies to all entities, true for record types and subtypes,
2710 -- includes class-wide types and subtypes (which are also records)
2712 -- Is_Remote_Call_Interface (Flag62)
2713 -- Present in all entities. Set in E_Package and E_Generic_Package
2714 -- entities to which a pragma Remote_Call_Interface is applied, and
2715 -- also on entities declared in the visible part of such a package.
2717 -- Is_Remote_Types (Flag61)
2718 -- Present in all entities. Set in E_Package and E_Generic_Package
2719 -- entities to which a pragma Remote_Types is applied, and also on
2720 -- entities declared in the visible part of the spec of such a package.
2722 -- Is_Renaming_Of_Object (Flag112)
2723 -- Present in all entities, set only for a variable or constant for
2724 -- which the Renamed_Object field is non-empty and for which the
2725 -- renaming is handled by the front end, by macro substitution of
2726 -- a copy of the (evaluated) name tree whereever the variable is used.
2728 -- Is_Return_Object (Flag209)
2729 -- Present in all object entities. True if the object is the return
2730 -- object of an extended_return_statement; False otherwise.
2732 -- Is_Safe_To_Reevaluate (Flag249)
2733 -- Present in all entities. Set in variables that are initialized by
2734 -- means of an assignment statement. When initialized their contents
2735 -- never change and hence they can be seen by the backend as constants.
2736 -- See also Is_True_Constant.
2738 -- Is_Scalar_Type (synthesized)
2739 -- Applies to all entities, true for scalar types and subtypes
2741 -- Is_Shared_Passive (Flag60)
2742 -- Present in all entities. Set in E_Package and E_Generic_Package
2743 -- entities to which a pragma Shared_Passive is applied, and also in
2744 -- all entities within such packages.
2746 -- Is_Standard_Character_Type (synthesized)
2747 -- Applies to all entities, true for types and subtypes whose root type
2748 -- is one of the standard character types (Character, Wide_Character,
2749 -- Wide_Wide_Character).
2751 -- Is_Statically_Allocated (Flag28)
2752 -- Present in all entities. This can only be set True for exception,
2753 -- variable, constant, and type/subtype entities. If the flag is set,
2754 -- then the variable or constant must be allocated statically rather
2755 -- than on the local stack frame. For exceptions, the meaning is that
2756 -- the exception data should be allocated statically (and indeed this
2757 -- flag is always set for exceptions, since exceptions do not have
2758 -- local scope). For a type, the meaning is that the type must be
2759 -- elaborated at the global level rather than locally. No type marked
2760 -- with this flag may depend on a local variable, or on any other type
2761 -- which does not also have this flag set to True. For a variable or
2762 -- or constant, if the flag is set, then the type of the object must
2763 -- either be declared at the library level, or it must also have the
2764 -- flag set (since to allocate the object statically, its type must
2765 -- also be elaborated globally).
2767 -- Is_String_Type (synthesized)
2768 -- Applies to all type entities. Determines if the given type is a
2769 -- string type, i.e. it is directly a string type or string subtype,
2770 -- or a string slice type, or an array type with one dimension and a
2771 -- component type that is a character type.
2773 -- Is_Subprogram (synthesized)
2774 -- Applies to all entities, true for function, procedure and operator
2777 -- Is_Synchronized_Interface (synthesized)
2778 -- Present in types that are interfaces. True if interface is declared
2779 -- synchronized, task, or protected, or is derived from a synchronized
2783 -- Present in E_Component and E_Constant entities. For regular tagged
2784 -- type this flag is set on the tag component (whose name is Name_uTag).
2785 -- For CPP_Class tagged types, this flag marks the pointer to the main
2786 -- vtable (i.e. the one to be extended by derivation).
2788 -- Is_Tagged_Type (Flag55)
2789 -- Present in all entities. Set for an entity for a tagged type.
2791 -- Is_Task_Interface (synthesized)
2792 -- Present in types that are interfaces. True if interface is declared as
2793 -- a task interface, or if it is derived from task interfaces.
2795 -- Is_Task_Record_Type (synthesized)
2796 -- Applies to all entities. True if Is_Concurrent_Record_Type
2797 -- Corresponding_Concurrent_Type is a task type.
2799 -- Is_Task_Type (synthesized)
2800 -- Applies to all entities. True for task types and subtypes
2802 -- Is_Thunk (Flag225)
2803 -- Present in all entities for subprograms (functions, procedures, and
2804 -- operators). True for subprograms that are thunks, that is small
2805 -- subprograms built by the expander for tagged types that cover
2806 -- interface types. At run-time thunks displace the pointer to the object
2807 -- (pointer named "this" in the C++ terminology) from a secondary
2808 -- dispatch table to the primary dispatch table associated with a given
2809 -- tagged type. Set by Expand_Interface Thunk and used by Expand_Call to
2810 -- handle extra actuals associated with accessibility level.
2812 -- Is_Trivial_Subprogram (Flag235)
2813 -- Present in all entities. Set in subprograms where either the body
2814 -- consists of a single null statement, or the first or only statement
2815 -- of the body raises an exception. This is used for suppressing certain
2816 -- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details.
2818 -- Is_True_Constant (Flag163)
2819 -- Present in all entities for constants and variables. Set in constants
2820 -- and variables which have an initial value specified but which are
2821 -- never assigned, partially or in the whole. For variables, it means
2822 -- that the variable was initialized but never modified, and hence can be
2823 -- treated as a constant by the code generator. For a constant, it means
2824 -- that the constant was not modified by generated code (e.g. to set a
2825 -- discriminant in an init proc). Assignments by user or generated code
2826 -- will reset this flag. See also Is_Safe_To_Reevaluate.
2828 -- Is_Type (synthesized)
2829 -- Applies to all entities, true for a type entity
2831 -- Is_Unchecked_Union (Flag117) [implementation base type only]
2832 -- Present in all entities. Set only in record types to which the
2833 -- pragma Unchecked_Union has been validly applied.
2835 -- Is_Underlying_Record_View (Flag246) [base type only]
2836 -- Present in all entities. Set only in record types that represent the
2837 -- underlying record view. This view is built for derivations of types
2838 -- with unknown discriminants; it is a record with the same structure
2839 -- as its corresponding record type, but whose parent is the full view
2840 -- of the parent in the original type extension.
2842 -- Is_Unsigned_Type (Flag144)
2843 -- Present in all types, but can be set only for discrete and fixed-point
2844 -- type and subtype entities. This flag is only valid if the entity is
2845 -- frozen. If set it indicates that the representation is known to be
2846 -- unsigned (i.e. that no negative values appear in the range). This is
2847 -- normally just a reflection of the lower bound of the subtype or base
2848 -- type, but there is one case in which the setting is non-obvious,
2849 -- namely the case of an unsigned subtype of a signed type from which
2850 -- a further subtype is obtained using variable bounds. This further
2851 -- subtype is still unsigned, but this cannot be determined by looking
2852 -- at its bounds or the bounds of the corresponding base type.
2854 -- Is_Valued_Procedure (Flag127)
2855 -- Present in procedure entities. Set if an Import_Valued_Procedure
2856 -- or Export_Valued_Procedure pragma applies to the procedure entity.
2858 -- Is_Visible_Child_Unit (Flag116)
2859 -- Present in compilation units that are child units. Once compiled,
2860 -- child units remain chained to the entities in the parent unit, and
2861 -- a separate flag must be used to indicate whether the names are
2862 -- visible by selected notation, or not.
2864 -- Is_Visible_Formal (Flag206)
2865 -- Present in all entities. Set True for instances of the formals of a
2866 -- formal package. Indicates that the entity must be made visible in the
2867 -- body of the instance, to reproduce the visibility of the generic.
2868 -- This simplifies visibility settings in instance bodies.
2870 -- Is_VMS_Exception (Flag133)
2871 -- Present in all entities. Set only for exception entities where the
2872 -- exception was specified in an Import_Exception or Export_Exception
2873 -- pragma with the VMS option for Form. See description of these pragmas
2874 -- for details. This flag can only be set in OpenVMS versions of GNAT.
2876 -- Is_Volatile (Flag16)
2877 -- Present in all type entities, and also in constants, components and
2878 -- variables. Set if a pragma Volatile applies to the entity. Also set
2879 -- if pragma Shared or pragma Atomic applies to entity. In the case of
2880 -- private or incomplete types, this flag is set in both the private
2881 -- and full view. The flag is not set reliably on private subtypes,
2882 -- and is always retrieved from the base type (but this is not a base-
2883 -- type-only attribute because it applies to other entities). Note that
2884 -- the back end should use Treat_As_Volatile, rather than Is_Volatile
2885 -- to indicate code generation requirements for volatile variables.
2886 -- Similarly, any front end test which is concerned with suppressing
2887 -- optimizations on volatile objects should test Treat_As_Volatile
2888 -- rather than testing this flag.
2890 -- Is_Wrapper_Package (synthesized)
2891 -- Present in package entities. Indicates that the package has been
2892 -- created as a wrapper for a subprogram instantiation.
2894 -- Itype_Printed (Flag202)
2895 -- Present in all type and subtype entities. Set in Itypes if the Itype
2896 -- has been printed by Sprint. This is used to avoid printing an Itype
2899 -- Kill_Elaboration_Checks (Flag32)
2900 -- Present in all entities. Set by the expander to kill elaboration
2901 -- checks which are known not to be needed. Equivalent in effect to
2902 -- the use of pragma Suppress (Elaboration_Checks) for that entity
2903 -- except that the effect is permanent and cannot be undone by a
2904 -- subsequent pragma Unsuppress.
2906 -- Kill_Range_Checks (Flag33)
2907 -- Present in all entities. Equivalent in effect to the use of pragma
2908 -- Suppress (Range_Checks) for that entity except that the result is
2909 -- permanent and cannot be undone by a subsequent pragma Unsuppress.
2910 -- This is currently only used in one odd situation in Sem_Ch3 for
2911 -- record types, and it would be good to get rid of it???
2913 -- Kill_Tag_Checks (Flag34)
2914 -- Present in all entities. Set by the expander to kill elaboration
2915 -- checks which are known not to be needed. Equivalent in effect to
2916 -- the use of pragma Suppress (Tag_Checks) for that entity except
2917 -- that the result is permanent and cannot be undone by a subsequent
2918 -- pragma Unsuppress.
2920 -- Known_To_Have_Preelab_Init (Flag207)
2921 -- Present in all type and subtype entities. If set, then the type is
2922 -- known to have preelaborable initialization. In the case of a partial
2923 -- view of a private type, it is only possible for this to be set if a
2924 -- pragma Preelaborable_Initialization is given for the type. For other
2925 -- types, it is never set if the type does not have preelaborable
2926 -- initialization, it may or may not be set if the type does have
2927 -- preelaborable initialization.
2929 -- Last_Assignment (Node26)
2930 -- Present in entities for variables, and OUT or IN OUT formals. Set for
2931 -- a local variable or formal to point to the left side of an assignment
2932 -- statement assigning a value to the variable. Cleared if the value of
2933 -- the entity is referenced. Used to warn about dubious assignment
2934 -- statements whose value is not used.
2936 -- Last_Entity (Node20)
2937 -- Present in all entities which act as scopes to which a list of
2938 -- associated entities is attached (blocks, class subtypes and types,
2939 -- entries, functions, loops, packages, procedures, protected objects,
2940 -- record types and subtypes, private types, task types and subtypes).
2941 -- Points to the last entry in the list of associated entities chained
2942 -- through the Next_Entity field. Empty if no entities are chained.
2944 -- Last_Formal (synthesized)
2945 -- Applies to subprograms and subprogram types, and also in entries
2946 -- and entry families. Returns last formal of the subprogram or entry.
2947 -- The formals are the first entities declared in a subprogram or in
2948 -- a subprogram type (the designated type of an Access_To_Subprogram
2949 -- definition) or in an entry.
2951 -- Limited_View (Node23)
2952 -- Present in non-generic package entities that are not instances. Bona
2953 -- fide package with the limited-view list through the first_entity and
2954 -- first_private attributes. The elements of this list are the shadow
2955 -- entities created for the types and local packages that are declared
2956 -- in a package appearing in a limited_with clause (Ada 2005: AI-50217)
2958 -- Lit_Indexes (Node15)
2959 -- Present in enumeration types and subtypes. Non-empty only for the
2960 -- case of an enumeration root type, where it contains the entity for
2961 -- the generated indexes entity. See unit Exp_Imgv for full details of
2962 -- the nature and use of this entity for implementing the Image and
2963 -- Value attributes for the enumeration type in question.
2965 -- Lit_Strings (Node16)
2966 -- Present in enumeration types and subtypes. Non-empty only for the
2967 -- case of an enumeration root type, where it contains the entity for
2968 -- the literals string entity. See unit Exp_Imgv for full details of
2969 -- the nature and use of this entity for implementing the Image and
2970 -- Value attributes for the enumeration type in question.
2972 -- Low_Bound_Tested (Flag205)
2973 -- Present in all entities. Currently this can only be set True for
2974 -- formal parameter entries of a standard unconstrained one-dimensional
2975 -- array or string type. Indicates that an explicit test of the low bound
2976 -- of the formal appeared in the code, e.g. in a pragma Assert. If this
2977 -- flag is set, warnings about assuming the index low bound to be one
2980 -- Machine_Radix_10 (Flag84)
2981 -- Present in decimal types and subtypes, set if the Machine_Radix is 10,
2982 -- as the result of the specification of a machine radix representation
2983 -- clause. Note that it is possible for this flag to be set without
2984 -- having Has_Machine_Radix_Clause True. This happens when a type is
2985 -- derived from a type with a clause present.
2987 -- Master_Id (Node17)
2988 -- Present in access types and subtypes. Empty unless Has_Task is
2989 -- set for the designated type, in which case it points to the entity
2990 -- for the Master_Id for the access type master. Also set for access-to-
2991 -- limited-class-wide types whose root may be extended with task
2992 -- components, and for access-to-limited-interfaces because they can be
2993 -- used to reference tasks implementing such interface.
2995 -- Materialize_Entity (Flag168)
2996 -- Present in all entities. Set only for renamed obects which should be
2997 -- materialized for debugging purposes. This means that a memory location
2998 -- containing the renamed address should be allocated. This is needed so
2999 -- that the debugger can find the entity.
3001 -- Mechanism (Uint8) (returned as Mechanism_Type)
3002 -- Present in functions and non-generic formal parameters. Indicates
3003 -- the mechanism to be used for the function return or for the formal
3004 -- parameter. See separate section on passing mechanisms. This field
3005 -- is also set (to the default value of zero) in a subprogram body
3006 -- entity but not used in this context.
3008 -- Modulus (Uint17) [base type only]
3009 -- Present in modular types. Contains the modulus. For the binary case,
3010 -- this will be a power of 2, but if Non_Binary_Modulus is set, then it
3011 -- will not be a power of 2.
3013 -- Must_Be_On_Byte_Boundary (Flag183)
3014 -- Present in entities for types and subtypes. Set if objects of the type
3015 -- must always be allocated on a byte boundary (more accurately a storage
3016 -- unit boundary). The front end checks that component clauses respect
3017 -- this rule, and the back end ensures that record packing does not
3018 -- violate this rule. Currently the flag is set only for packed arrays
3019 -- longer than 64 bits where the component size is not a power of 2.
3021 -- Must_Have_Preelab_Init (Flag208)
3022 -- Present in entities for types and subtypes. Set in the full type of a
3023 -- private type or subtype if a pragma Has_Preelaborable_Initialization
3024 -- is present for the private type. Used to check that the full type has
3025 -- preelaborable initialization at freeze time (this has to be deferred
3026 -- to the freeze point because of the rule about overriding Initialize).
3028 -- Needs_Debug_Info (Flag147)
3029 -- Present in all entities. Set if the entity requires normal debugging
3030 -- information to be generated. This is true of all entities that have
3031 -- Comes_From_Source set, and also transitively for entities associated
3032 -- with such components (e.g. their types). It is true for all entities
3033 -- in Debug_Generated_Code mode (-gnatD switch). This is the flag that
3034 -- the back end should check to determine whether or not to generate
3035 -- debugging information for an entity. Note that callers should always
3036 -- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info,
3037 -- so that the flag is set properly on subsidiary entities.
3039 -- Needs_No_Actuals (Flag22)
3040 -- Present in callable entities (subprograms, entries, access to
3041 -- subprograms) which can be called without actuals because all of
3042 -- their formals (if any) have default values. This flag simplifies the
3043 -- resolution of the syntactic ambiguity involving a call to these
3044 -- entities when the return type is an array type, and a call can be
3045 -- interpreted as an indexing of the result of the call. It is also
3046 -- used to resolve various cases of entry calls.
3048 -- Never_Set_In_Source (Flag115)
3049 -- Present in all entities, but can be set only for variables and
3050 -- parameters. This flag is set if the object is never assigned a value
3051 -- in user source code, either by assignment or by being used as an out
3052 -- or in out parameter. Note that this flag is not reset from using an
3053 -- initial value, so if you want to test for this case as well, test the
3054 -- Has_Initial_Value flag also.
3056 -- This flag is only for the purposes of issuing warnings, it must not
3057 -- be used by the code generator to indicate that the variable is in
3058 -- fact a constant, since some assignments in generated code do not
3059 -- count (for example, the call to an init proc to assign some but
3060 -- not all of the fields in a partially initialized record). The code
3061 -- generator should instead use the flag Is_True_Constant.
3063 -- For the purposes of this warning, the default assignment of
3064 -- access variables to null is not considered the assignment of
3065 -- of a value (so the warning can be given for code that relies
3066 -- on this initial null value, when no other value is ever set).
3068 -- In variables and out parameters, if this flag is set after full
3069 -- processing of the corresponding declarative unit, it indicates that
3070 -- the variable or parameter was never set, and a warning message can
3073 -- Note: this flag is initially set, and then cleared on encountering
3074 -- any construct that might conceivably legitimately set the value.
3075 -- Thus during the analysis of a declarative region and its associated
3076 -- statement sequence, the meaning of the flag is "not set yet", and
3077 -- once this analysis is complete the flag means "never assigned".
3079 -- Note: for variables appearing in package declarations, this flag
3080 -- is never set. That is because there is no way to tell if some
3081 -- client modifies the variable (or in the case of variables in the
3082 -- private part, if some child unit modifies the variables).
3084 -- Note: in the case of renamed objects, the flag must be set in the
3085 -- ultimate renamed object. Clients noting a possible modification
3086 -- should use the Note_Possible_Modification procedure in Sem_Util
3087 -- rather than Set_Never_Set_In_Source precisely to deal properly with
3088 -- the renaming possibility.
3090 -- Next_Component (synthesized)
3091 -- Applies to record components. Returns the next component by following
3092 -- the chain of declared entities until one is found which corresponds to
3093 -- a component (Ekind is E_Component). Any internal types generated from
3094 -- the subtype indications of the record components are skipped. Returns
3095 -- Empty if no more components.
3097 -- Next_Component_Or_Discriminant (synthesized)
3098 -- Similar to Next_Component, but includes components and discriminants
3099 -- so the input can have either E_Component or E_Discriminant, and the
3100 -- same is true for the result. Returns Empty if no more components or
3101 -- discriminants in the record.
3103 -- Next_Discriminant (synthesized)
3104 -- Applies to discriminants returned by First/Next_Discriminant.
3105 -- Returns the next language-defined (ie: perhaps non-girder)
3106 -- discriminant by following the chain of declared entities as long as
3107 -- the kind of the entity corresponds to a discriminant. Note that the
3108 -- discriminants might be the only components of the record.
3109 -- Returns Empty if there are no more.
3111 -- Next_Entity (Node2)
3112 -- Present in all entities. The entities of a scope are chained, with
3113 -- the head of the list being in the First_Entity field of the scope
3114 -- entity. All entities use the Next_Entity field as a forward pointer
3115 -- for this list, with Empty indicating the end of the list. Since this
3116 -- field is in the base part of the entity, the access routines for this
3117 -- field are in Sinfo.
3119 -- Next_Formal (synthesized)
3120 -- Applies to the entity for a formal parameter. Returns the next
3121 -- formal parameter of the subprogram or subprogram type. Returns
3122 -- Empty if there are no more formals.
3124 -- Next_Formal_With_Extras (synthesized)
3125 -- Applies to the entity for a formal parameter. Returns the next
3126 -- formal parameter of the subprogram or subprogram type. Returns
3127 -- Empty if there are no more formals. The list returned includes
3128 -- all the extra formals (see description of Extra_Formal field)
3130 -- Next_Index (synthesized)
3131 -- Applies to array types and subtypes and to string types and
3132 -- subtypes. Yields the next index. The first index is obtained by
3133 -- using the First_Index attribute, and then subsequent indexes are
3134 -- obtained by applying Next_Index to the previous index. Empty is
3135 -- returned to indicate that there are no more indexes. Note that
3136 -- unlike most attributes in this package, Next_Index applies to
3137 -- nodes for the indexes, not to entities.
3139 -- Next_Inlined_Subprogram (Node12)
3140 -- Present in subprograms. Used to chain inlined subprograms used in
3141 -- the current compilation, in the order in which they must be compiled
3142 -- by Gigi to insure that all inlinings are performed.
3144 -- Next_Literal (synthesized)
3145 -- Applies to enumeration literals, returns the next literal, or
3146 -- Empty if applied to the last literal. This is actually a synonym
3147 -- for Next, but its use is preferred in this context.
3149 -- Non_Binary_Modulus (Flag58) [base type only]
3150 -- Present in all subtype and type entities. Set for modular integer
3151 -- types if the modulus value is other than a power of 2.
3153 -- Non_Limited_View (Node17)
3154 -- Present in incomplete types that are the shadow entities created
3155 -- when analyzing a limited_with_clause (Ada 2005: AI-50217). Points to
3156 -- the defining entity in the original declaration.
3158 -- Nonzero_Is_True (Flag162) [base type only]
3159 -- Present in enumeration types. True if any non-zero value is to be
3160 -- interpreted as true. Currently this is set true for derived Boolean
3161 -- types which have a convention of C, C++ or Fortran.
3163 -- No_Pool_Assigned (Flag131) [root type only]
3164 -- Present in access types. Set if a storage size clause applies to the
3165 -- variable with a static expression value of zero. This flag is used to
3166 -- generate errors if any attempt is made to allocate or free an instance
3167 -- of such an access type. This is set only in the root type, since
3168 -- derived types must have the same pool.
3170 -- No_Return (Flag113)
3171 -- Present in all entities. Always false except in the case of procedures
3172 -- and generic procedures for which a pragma No_Return is given.
3174 -- Normalized_First_Bit (Uint8)
3175 -- Present in components and discriminants. Indicates the normalized
3176 -- value of First_Bit for the component, i.e. the offset within the
3177 -- lowest addressed storage unit containing part or all of the field.
3178 -- Set to No_Uint if no first bit position is assigned yet.
3180 -- Normalized_Position (Uint14)
3181 -- Present in components and discriminants. Indicates the normalized
3182 -- value of Position for the component, i.e. the offset in storage
3183 -- units from the start of the record to the lowest addressed storage
3184 -- unit containing part or all of the field.
3186 -- Normalized_Position_Max (Uint10)
3187 -- Present in components and discriminants. For almost all cases, this
3188 -- is the same as Normalized_Position. The one exception is for the case
3189 -- of a discriminated record containing one or more arrays whose length
3190 -- depends on discriminants. In this case, the Normalized_Position_Max
3191 -- field represents the maximum possible value of Normalized_Position
3192 -- assuming min/max values for discriminant subscripts in all fields.
3193 -- This is used by Layout in front end layout mode to properly computed
3194 -- the maximum size such records (needed for allocation purposes when
3195 -- there are default discriminants, and also for the 'Size value).
3197 -- No_Strict_Aliasing (Flag136) [base type only]
3198 -- Present in access types. Set to direct the back end to avoid any
3199 -- optimizations based on an assumption about the aliasing status of
3200 -- objects designated by the access type. For the case of the gcc
3201 -- back end, the effect is as though all references to objects of
3202 -- the type were compiled with -fno-strict-aliasing. This flag is
3203 -- set if an unchecked conversion with the access type as a target
3204 -- type occurs in the same source unit as the declaration of the
3205 -- access type, or if an explicit pragma No_Strict_Aliasing applies.
3207 -- Number_Dimensions (synthesized)
3208 -- Applies to array types and subtypes. Returns the number of dimensions
3209 -- of the array type or subtype as a value of type Pos.
3211 -- Number_Entries (synthesized)
3212 -- Applies to concurrent types. Returns the number of entries that are
3213 -- declared within the task or protected definition for the type.
3215 -- Number_Formals (synthesized)
3216 -- Applies to subprograms and subprogram types. Yields the number of
3217 -- formals as a value of type Pos.
3219 -- OK_To_Rename (Flag247)
3220 -- Present only in entities for variables. If this flag is set, it
3221 -- means that if the entity is used as the initial value of an object
3222 -- declaration, the object declaration can be safely converted into a
3223 -- renaming to avoid an extra copy. This is set for variables which are
3224 -- generated by the expander to hold the result of evaluating some
3225 -- expression. Most notably, the local variables used to store the result
3226 -- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It
3227 -- is only worth setting this flag for composites, since for primitive
3228 -- types, it is cheaper to do the copy.
3230 -- OK_To_Reorder_Components (Flag239) [base type only]
3231 -- Present in record types. Set if the back end is permitted to reorder
3232 -- the components. If not set, the record must be layed out in the order
3233 -- in which the components are declared textually. Currently this flag
3234 -- can only be set by debug switches.
3236 -- Optimize_Alignment_Space (Flag241)
3237 -- A flag present in type, subtype, variable, and constant entities. This
3238 -- flag records that the type or object is to be layed out in a manner
3239 -- consistent with Optimize_Alignment (Space) mode. The compiler and
3240 -- binder ensure a consistent view of any given type or object. If pragma
3241 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3242 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3244 -- Optimize_Alignment_Time (Flag242)
3245 -- A flag present in type, subtype, variable, and constant entities. This
3246 -- flag records that the type or object is to be layed out in a manner
3247 -- consistent with Optimize_Alignment (Time) mode. The compiler and
3248 -- binder ensure a consistent view of any given type or object. If pragma
3249 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3250 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3252 -- Original_Access_Type (Node26)
3253 -- Present in E_Access_Subprogram_Type entities. Set only if the access
3254 -- type was generated by the expander as part of processing an access
3255 -- to protected subprogram type. Points to the access to protected
3258 -- Original_Array_Type (Node21)
3259 -- Present in modular types and array types and subtypes. Set only
3260 -- if the Is_Packed_Array_Type flag is set, indicating that the type
3261 -- is the implementation type for a packed array, and in this case it
3262 -- points to the original array type for which this is the packed
3263 -- array implementation type.
3265 -- Original_Record_Component (Node22)
3266 -- Present in components, including discriminants. The usage depends
3267 -- on whether the record is a base type and whether it is tagged.
3269 -- In base tagged types:
3270 -- When the component is inherited in a record extension, it points
3271 -- to the original component (the entity of the ancestor component
3272 -- which is not itself inherited) otherwise it points to itself.
3273 -- Gigi uses this attribute to implement the automatic dereference in
3274 -- the extension and to apply the transformation:
3276 -- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
3278 -- In base non-tagged types:
3279 -- Always points to itself except for non-girder discriminants, where
3280 -- it points to the girder discriminant it renames.
3282 -- In subtypes (tagged and untagged):
3283 -- Points to the component in the base type.
3285 -- Overlays_Constant (Flag243)
3286 -- Present in all entities. Set only for a variable for which there is
3287 -- an address clause which causes the variable to overlay a constant.
3289 -- Overridden_Operation (Node26)
3290 -- Present in subprograms. For overriding operations, points to the
3291 -- user-defined parent subprogram that is being overridden. Note: this
3292 -- attribute uses the same field as Static_Initialization. The latter
3293 -- is only defined for internal initialization procedures, for which
3294 -- Overridden_Operation is irrelevant. Thus this attribute must not be
3295 -- set for init_procs.
3297 -- Package_Instantiation (Node26)
3298 -- Present in packages and generic packages. When present, this field
3299 -- references an N_Generic_Instantiation node associated with an
3300 -- instantiated package. In the case where the referenced node has
3301 -- been rewritten to an N_Package_Specification, the instantiation
3302 -- node is available from the Original_Node field of the package spec
3303 -- node. This is currently not guaranteed to be set in all cases, but
3304 -- when set, the field is used in Get_Package_Instantiation_Node as
3305 -- one of the means of obtaining the instantiation node. Eventually
3306 -- it should be set in all cases, including package entities associated
3307 -- with formal packages. ???
3309 -- Packed_Array_Type (Node23)
3310 -- Present in array types and subtypes, including the string literal
3311 -- subtype case, if the corresponding type is packed (either bit packed
3312 -- or packed to eliminate holes in non-contiguous enumeration type index
3313 -- types). References the type used to represent the packed array, which
3314 -- is either a modular type for short static arrays, or an array of
3315 -- System.Unsigned. Note that in some situations (internal types, and
3316 -- references to fields of variant records), it is not always possible
3317 -- to construct this type in advance of its use. If Packed_Array_Type
3318 -- is empty, then the necessary type is declared on the fly for each
3319 -- reference to the array.
3321 -- Parameter_Mode (synthesized)
3322 -- Applies to formal parameter entities. This is a synonym for Ekind,
3323 -- used when obtaining the formal kind of a formal parameter (the result
3324 -- is one of E_[In/Out/In_Out]_Parameter)
3326 -- Parent_Subtype (Node19) [base type only]
3327 -- Present in E_Record_Type. Set only for derived tagged types, in which
3328 -- case it points to the subtype of the parent type. This is the type
3329 -- that is used as the Etype of the _parent field.
3331 -- Postcondition_Proc (Node8)
3332 -- Present only in procedure entities, saves the entity of the generated
3333 -- postcondition proc if one is present, otherwise is set to Empty. Used
3334 -- to generate the call to this procedure in case the expander inserts
3335 -- implicit return statements.
3337 -- PPC_Wrapper (Node25)
3338 -- Present in entries and entry families. Set only if pre- or post-
3339 -- conditions are present. The precondition_wrapper body is the original
3340 -- entry call, decorated with the given precondition for the entry.
3342 -- Primitive_Operations (synthesized)
3343 -- Present in concurrent types, tagged record types and subtypes, tagged
3344 -- private types and tagged incomplete types. For concurrent types whose
3345 -- Corresponding_Record_Type (CRT) is available, returns the list of
3346 -- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist.
3347 -- For all the other types returns the Direct_Primitive_Operations.
3349 -- Predicate_Function (synthesized)
3350 -- Present in all types. Set for types for which (Has_Predicates is True)
3351 -- and for which a predicate procedure has been built that tests that the
3352 -- specified predicates are True. Contains the entity for the function
3353 -- which takes a single argument of the given type, and returns True if
3354 -- the predicate holds and False if it does not.
3356 -- Note: the reason this is marked as a synthesized attribute is that the
3357 -- way this is stored is as an element of the Subprograms_For_Type field.
3360 -- Present in private components of protected types. Refers to the entity
3361 -- of the component renaming declaration generated inside protected
3362 -- subprograms, entries or barrier functions.
3364 -- Prival_Link (Node20)
3365 -- Present in constants and variables which rename private components of
3366 -- protected types. Set to the original private component.
3368 -- Private_Dependents (Elist18)
3369 -- Present in private (sub)types. Records the subtypes of the private
3370 -- type, derivations from it, and records and arrays with components
3371 -- dependent on the type.
3373 -- The subtypes are traversed when installing and deinstalling (the full
3374 -- view of) a private type in order to ensure correct view of the
3377 -- Used in similar fashion for incomplete types: holds list of subtypes
3378 -- of these incomplete types that have discriminant constraints. The
3379 -- full views of these subtypes are constructed when the full view of
3380 -- the incomplete type is processed.
3382 -- In addition, if the incomplete type is the designated type in an
3383 -- access definition for an access parameter, the operation may be
3384 -- a dispatching primitive operation, which is only known when the full
3385 -- declaration of the type is seen. Subprograms that have such an
3386 -- access parameter are also placed in the list of private_dependents.
3388 -- Private_View (Node22)
3389 -- For each private type, three entities are allocated, the private view,
3390 -- the full view, and the shadow entity. The shadow entity contains a
3391 -- copy of the private view and is used for restoring the proper private
3392 -- view after a region in which the full view is visible (and is copied
3393 -- into the entity normally used for the private view during this period
3394 -- of visibility). The Private_View field is self-referential when the
3395 -- private view lives in its normal entity, but in the copy that is made
3396 -- in the shadow entity, it points to the proper location in which to
3397 -- restore the private view saved in the shadow.
3399 -- Protected_Formal (Node22)
3400 -- Present in formal parameters (in, in out and out parameters). Used
3401 -- only for formals of protected operations. References corresponding
3402 -- formal parameter in the unprotected version of the operation that
3403 -- is created during expansion.
3405 -- Protected_Body_Subprogram (Node11)
3406 -- Present in protected operations. References the entity for the
3407 -- subprogram which implements the body of the operation.
3409 -- Protection_Object (Node23)
3410 -- Applies to protected entries, entry families and subprograms. Denotes
3411 -- the entity which is used to rename the _object component of protected
3414 -- Reachable (Flag49)
3415 -- Present in labels. The flag is set over the range of statements in
3416 -- which a goto to that label is legal.
3418 -- Referenced (Flag156)
3419 -- Present in all entities. Set if the entity is referenced, except for
3420 -- the case of an appearance of a simple variable that is not a renaming
3421 -- as the left side of an assignment in which case Referenced_As_LHS is
3422 -- set instead, or a similar appearance as an out parameter actual, in
3423 -- which case Referenced_As_Out_Parameter is set.
3425 -- Referenced_As_LHS (Flag36):
3426 -- Present in all entities. This flag is set instead of Referenced if a
3427 -- simple variable that is not a renaming appears as the left side of an
3428 -- assignment. The reason we distinguish this kind of reference is that
3429 -- we have a separate warning for variables that are only assigned and
3432 -- Referenced_As_Out_Parameter (Flag227):
3433 -- Present in all entities. This flag is set instead of Referenced if a
3434 -- simple variable that is not a renaming appears as an actual for an out
3435 -- formal. The reason we distinguish this kind of reference is that
3436 -- we have a separate warning for variables that are only assigned and
3437 -- never read, and out parameters are a special case.
3439 -- Register_Exception_Call (Node20)
3440 -- Present in exception entities. When an exception is declared,
3441 -- a call is expanded to Register_Exception. This field points to
3442 -- the expanded N_Procedure_Call_Statement node for this call. It
3443 -- is used for Import/Export_Exception processing to modify the
3444 -- register call to make appropriate entries in the special tables
3445 -- used for handling these pragmas at runtime.
3447 -- Related_Array_Object (Node19)
3448 -- Present in array types and subtypes. Used only for the base type
3449 -- and subtype created for an anonymous array object. Set to point
3450 -- to the entity of the corresponding array object. Currently used
3451 -- only for type-related error messages.
3453 -- Related_Expression (Node24)
3454 -- Present in variables and types. Set only for internally generated
3455 -- entities, where it may be used to denote the source expression whose
3456 -- elaboration created the variable declaration. If set, it is used
3457 -- for generating clearer messages from CodePeer.
3459 -- Shouldn't it also be used for the same purpose in errout? It seems
3460 -- odd to have two mechanisms here???
3462 -- Related_Instance (Node15)
3463 -- Present in the wrapper packages created for subprogram instances.
3464 -- The internal subprogram that implements the instance is inside the
3465 -- wrapper package, but for debugging purposes its external symbol
3466 -- must correspond to the name and scope of the related instance.
3468 -- Related_Type (Node27)
3469 -- Present in components, constants and variables. Set when there is an
3470 -- associated dispatch table to point to entities containing primary or
3471 -- secondary tags. Not set in the _tag component of record types.
3473 -- Relative_Deadline_Variable (Node26) [implementation base type only]
3474 -- Present in task type entities. This flag is set if a valid and
3475 -- effective pragma Relative_Deadline applies to the base type. Points
3476 -- to the entity for a variable that is created to hold the value given
3477 -- in a Relative_Deadline pragma for a task type.
3479 -- Renamed_Entity (Node18)
3480 -- Present in exceptions, packages, subprograms and generic units. Set
3481 -- for entities that are defined by a renaming declaration. Denotes the
3482 -- renamed entity, or transitively the ultimate renamed entity if
3483 -- there is a chain of renaming declarations. Empty if no renaming.
3485 -- Renamed_In_Spec (Flag231)
3487 -- Present in package entities. If a package renaming occurs within
3488 -- a package spec, then this flag is set on the renamed package. The
3489 -- purpose is to prevent a warning about unused entities in the renamed
3490 -- package. Such a warning would be inappropriate since clients of the
3491 -- package can see the entities in the package via the renaming.
3493 -- Renamed_Object (Node18)
3494 -- Present in all objects (constants, variables, components, formal
3495 -- parameters, generic formal parameters, and loop parameters).
3496 -- ??? Present in discriminants?
3497 -- Set non-Empty if the object was declared by a renaming declaration,
3498 -- in which case it references the tree node for the name of the renamed
3499 -- object. This is only possible for the variable and constant cases.
3500 -- For formal parameters, this field is used in the course of inline
3501 -- expansion, to map the formals of a subprogram into the corresponding
3502 -- actuals. For formals of a task entry, it denotes the local renaming
3503 -- that replaces the actual within the accept statement. The field is
3504 -- Empty otherwise (it is always empty for loop parameters).
3506 -- Renaming_Map (Uint9)
3507 -- Present in generic subprograms, generic packages, and their
3508 -- instances. Also present in the instances of the corresponding
3509 -- bodies. Denotes the renaming map (generic entities => instance
3510 -- entities) used to construct the instance by givin an index into
3511 -- the tables used to represent these maps. See Sem_Ch12 for further
3512 -- details. The maps for package instances are also used when the
3513 -- instance is the actual corresponding to a formal package.
3515 -- Requires_Overriding (Flag213)
3516 -- Present in all subprograms and entries. Set for subprograms that
3517 -- require overriding as defined by RM-2005-3.9.3(6/2). Note that this
3518 -- is True only for implicitly declare subprograms; it is not set on the
3519 -- parent type's subprogram. See also Is_Abstract_Subprogram.
3521 -- Return_Flag_Or_Transient_Decl (Node15)
3522 -- Applies to variables and constants. Set for objects which act as the
3523 -- return value of an extended return statement. The node contains the
3524 -- entity of a locally declared flag which controls the finalization of
3525 -- the return object should the function fail. Also set for access-to-
3526 -- controlled objects used to provide a hook to controlled transients
3527 -- declared inside an Expression_With_Actions. The node contains the
3528 -- object declaration of the controlled transient.
3530 -- Return_Present (Flag54)
3531 -- Present in function and generic function entities. Set if the
3532 -- function contains a return statement (used for error checking).
3533 -- This flag can also be set in procedure and generic procedure
3534 -- entities (for convenience in setting it), but is only tested
3535 -- for the function case.
3537 -- Return_Applies_To (Node8)
3538 -- Present in E_Return_Statement. Points to the entity representing
3539 -- the construct to which the return statement applies, as defined in
3540 -- RM-6.5(4/2). Note that a (simple) return statement within an
3541 -- extended_return_statement applies to the extended_return_statement,
3542 -- even though it causes the whole function to return.
3544 -- Returns_By_Ref (Flag90)
3545 -- Present in function entities, to indicate that the function
3546 -- returns the result by reference, either because its return type is a
3547 -- by-reference-type or because it uses explicitly the secondary stack.
3549 -- Reverse_Bit_Order (Flag164) [base type only]
3550 -- Present in all record type entities. Set if entity has a Bit_Order
3551 -- aspect (set by an aspect clause or attribute definition clause) that
3552 -- has reversed the order of bits from the default value. When this flag
3553 -- is set, a component clause must specify a set of bits entirely within
3554 -- a single storage unit (Ada 95) or within a single machine scalar (see
3555 -- Ada 2005 AI-133), or must occupy an integral number of storage units.
3558 -- Present in all type and subtype entities. Contains the value of
3559 -- type'Size as defined in the RM. See also the Esize field and
3560 -- and the description on "Handling of Type'Size Values". A value
3561 -- of zero in this field for a non-discrete type means that
3562 -- the front end has not yet determined the size value. For the
3563 -- case of a discrete type, this field is always set by the front
3564 -- end and zero is a legitimate value for a type with one value.
3566 -- Root_Type (synthesized)
3567 -- Applies to all type entities. For class-wide types, return the root
3568 -- type of the class covered by the CW type, otherwise returns the
3569 -- ultimate derivation ancestor of the given type. This function
3570 -- preserves the view, i.e. the Root_Type of a partial view is the
3571 -- partial view of the ultimate ancestor, the Root_Type of a full view
3572 -- is the full view of the ultimate ancestor. Note that this function
3573 -- does not correspond exactly to the use of root type in the RM, since
3574 -- in the RM root type applies to a class of types, not to a type.
3576 -- Scalar_Range (Node20)
3577 -- Present in all scalar types (including modular types, where the
3578 -- bounds are 0 .. modulus - 1). References a node in the tree that
3579 -- contains the bounds for the range. Note that this information
3580 -- could be obtained by rummaging around the tree, but it is more
3581 -- convenient to have it immediately at hand in the entity. The
3582 -- contents of Scalar_Range can either be an N_Subtype_Indication
3583 -- node (with a constraint), or a Range node, but not a simple
3584 -- subtype reference (a subtype is converted into a range).
3586 -- Scale_Value (Uint15)
3587 -- Present in decimal fixed-point types and subtypes. Contains the scale
3588 -- for the type (i.e. the value of type'Scale = the number of decimal
3589 -- digits after the decimal point).
3592 -- Present in all entities. Points to the entity for the scope (block,
3593 -- loop, subprogram, package etc.) in which the entity is declared.
3594 -- Since this field is in the base part of the entity node, the access
3595 -- routines for this field are in Sinfo. Note that for a child package,
3596 -- the Scope will be the parent package, and for a non-child package,
3597 -- the Scope will be Standard.
3599 -- Scope_Depth (synthesized)
3600 -- Applies to program units, blocks, concurrent types and entries, and
3601 -- also to record types, i.e. to any entity that can appear on the scope
3602 -- stack. Yields the scope depth value, which for those entities other
3603 -- than records is simply the scope depth value, for record entities, it
3604 -- is the Scope_Depth of the record scope.
3606 -- Scope_Depth_Value (Uint22)
3607 -- Present in program units, blocks, concurrent types, and entries.
3608 -- Indicates the number of scopes that statically enclose the declaration
3609 -- of the unit or type. Library units have a depth of zero. Note that
3610 -- record types can act as scopes but do NOT have this field set (see
3611 -- Scope_Depth above)
3613 -- Scope_Depth_Set (synthesized)
3614 -- Applies to a special predicate function that returns a Boolean value
3615 -- indicating whether or not the Scope_Depth field has been set. It is
3616 -- needed, since returns an invalid value in this case!
3618 -- Sec_Stack_Needed_For_Return (Flag167)
3619 -- Present in scope entities (blocks, functions, procedures, tasks,
3620 -- entries). Set to True when secondary stack is used to hold the
3621 -- returned value of a function and thus should not be released on
3624 -- Shadow_Entities (List14)
3625 -- Present in package and generic package entities. Points to a list
3626 -- of entities that correspond to private types. For each private type
3627 -- a shadow entity is created that holds a copy of the private view.
3628 -- In regions of the program where the full views of these private
3629 -- entities are visible, the full view is copied into the entity that
3630 -- is normally used to hold the private view, but the shadow entity
3631 -- copy is unchanged. The shadow entities are then used to restore the
3632 -- original private views at the end of the region. This list is a
3633 -- standard format list (i.e. First (Shadow_Entities) is the first
3634 -- entry and subsequent entries are obtained using Next.
3636 -- Shared_Var_Procs_Instance (Node22)
3637 -- Present in variables. Set non-Empty only if Is_Shared_Passive is
3638 -- set, in which case this is the entity for the associated instance of
3639 -- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details.
3641 -- Size_Check_Code (Node19)
3642 -- Present in constants and variables. Normally Empty. Set if code is
3643 -- generated to check the size of the object. This field is used to
3644 -- suppress this code if a subsequent address clause is encountered.
3646 -- Size_Clause (synthesized)
3647 -- Applies to all entities. If a size clause is present in the rep
3648 -- item chain for an entity then the attribute definition clause node
3649 -- for the size clause is returned. Otherwise Size_Clause returns Empty
3650 -- if no item is present. Usually this is only meaningful if the flag
3651 -- Has_Size_Clause is set. This is because when the representation item
3652 -- chain is copied for a derived type, it can inherit a size clause that
3653 -- is not applicable to the entity.
3655 -- Size_Depends_On_Discriminant (Flag177)
3656 -- Present in all entities for types and subtypes. Indicates that the
3657 -- size of the type depends on the value of one or more discriminants.
3658 -- Currently, this flag is only set for arrays which have one or more
3659 -- bounds depending on a discriminant value.
3661 -- Size_Known_At_Compile_Time (Flag92)
3662 -- Present in all entities for types and subtypes. Indicates that the
3663 -- size of objects of the type is known at compile time. This flag is
3664 -- used to optimize some generated code sequences, and also to enable
3665 -- some error checks (e.g. disallowing component clauses on variable
3666 -- length objects). It is set conservatively (i.e. if it is True, the
3667 -- size is certainly known at compile time, if it is False, then the
3668 -- size may or may not be known at compile time, but the code will
3669 -- assume that it is not known).
3671 -- Small_Value (Ureal21)
3672 -- Present in fixed point types. Points to the universal real for the
3673 -- Small of the type, either as given in a representation clause, or
3674 -- as computed (as a power of two) by the compiler.
3676 -- Spec_Entity (Node19)
3677 -- Present in package body entities. Points to corresponding package
3678 -- spec entity. Also present in subprogram body parameters in the
3679 -- case where there is a separate spec, where this field references
3680 -- the corresponding parameter entities in the spec.
3682 -- Static_Predicate (List25)
3683 -- Present in discrete types/subtypes with predicates (Has_Predicates
3684 -- set True). Points to a list of expression and N_Range nodes that
3685 -- represent the predicate in canonical form. The canonical form has
3686 -- entries sorted in ascending order, with all duplicates eliminated,
3687 -- and adjacent ranges coalesced, so that there is always a gap in the
3688 -- values between successive entries. The entries in this list are
3689 -- fully analyzed and typed with the base type of the subtype. Note
3690 -- that all entries are static and have values within the subtype range.
3692 -- Storage_Size_Variable (Node15) [implementation base type only]
3693 -- Present in access types and task type entities. This flag is set
3694 -- if a valid and effective pragma Storage_Size applies to the base
3695 -- type. Points to the entity for a variable that is created to
3696 -- hold the value given in a Storage_Size pragma for an access
3697 -- collection or a task type. Note that in the access type case,
3698 -- this field is present only in the root type (since derived types
3699 -- share the same storage pool).
3701 -- Static_Elaboration_Desired (Flag77)
3702 -- Present in library-level packages. Set by the pragma of the same
3703 -- name, to indicate that static initialization must be attempted for
3704 -- all types declared in the package, and that a warning must be emitted
3705 -- for those types to which static initialization is not available.
3707 -- Static_Initialization (Node26)
3708 -- Present in initialization procedures for types whose objects can be
3709 -- initialized statically. The value of this attribute is a positional
3710 -- aggregate whose components are compile-time static values. Used
3711 -- when available in object declarations to eliminate the call to the
3712 -- initialization procedure, and to minimize elaboration code. Note:
3713 -- This attribute uses the same field as Overridden_Operation, which is
3714 -- irrelevant in init_procs.
3716 -- Stored_Constraint (Elist23)
3717 -- Present in entities that can have discriminants (concurrent types
3718 -- subtypes, record types and subtypes, private types and subtypes,
3719 -- limited private types and subtypes and incomplete types). Points
3720 -- to an element list containing the expressions for each of the
3721 -- stored discriminants for the record (sub)type.
3723 -- Strict_Alignment (Flag145) [implementation base type only]
3724 -- Present in all type entities. Indicates that some containing part
3725 -- is either aliased or tagged. This prohibits packing the object
3726 -- tighter than its natural size and alignment.
3728 -- String_Literal_Length (Uint16)
3729 -- Present in string literal subtypes (which are created to correspond
3730 -- to string literals in the program). Contains the length of the string
3733 -- String_Literal_Low_Bound (Node15)
3734 -- Present in string literal subtypes (which are created to correspond
3735 -- to string literals in the program). Contains an expression whose
3736 -- value represents the low bound of the literal. This is a copy of
3737 -- the low bound of the applicable index constraint if there is one,
3738 -- or a copy of the low bound of the index base type if not.
3740 -- Subprograms_For_Type (Node29)
3741 -- Present in all type entities, and in subprogram entities. This is used
3742 -- to hold a list of subprogram entities for subprograms associated with
3743 -- the type, linked through the Subprogram_List field of the subprogram
3744 -- entity. Basically this is a way of multiplexing the single field to
3745 -- hold more than one entity (since we ran out of space in some type
3746 -- entities). This is currently used for Invariant_Procedure and also
3747 -- for Predicate_Function, and clients will always use the latter two
3748 -- names to access entries in this list.
3750 -- Suppress_Elaboration_Warnings (Flag148)
3751 -- Present in all entities, can be set only for subprogram entities and
3752 -- for variables. If this flag is set then Sem_Elab will not generate
3753 -- elaboration warnings for the subprogram or variable. Suppression of
3754 -- such warnings is automatic for subprograms for which elaboration
3755 -- checks are suppressed (without the need to set this flag), but the
3756 -- flag is also set for various internal entities (such as init procs)
3757 -- which are known not to generate any possible access before
3758 -- elaboration, and it is set on variables when a warning is given to
3759 -- avoid multiple elaboration warnings for the same variable.
3761 -- Suppress_Initialization (Flag105)
3762 -- Present in all type and subtype entities. If set for the base type,
3763 -- then the generation of initialization procedures is suppressed for the
3764 -- type. Any other implicit initialiation (e.g. from the use of pragma
3765 -- Initialize_Scalars) is also suppressed if this flag is set either for
3766 -- the subtype in question, or for the base type. Set by use of pragma
3767 -- Suppress_Initialization and also for internal entities where we know
3768 -- that no initialization is required. For example, enumeration image
3769 -- table entities set it.
3771 -- Suppress_Style_Checks (Flag165)
3772 -- Present in all entities. Suppresses any style checks specifically
3773 -- associated with the given entity if set.
3775 -- Suppress_Value_Tracking_On_Call (Flag217)
3776 -- Present in all entities. Set in a scope entity if value tracking is to
3777 -- be suppressed on any call within the scope. Used when an access to a
3778 -- local subprogram is computed, to deal with the possibility that this
3779 -- value may be passed around, and if used, may clobber a local variable.
3781 -- Task_Body_Procedure (Node25)
3782 -- Present in task types and subtypes. Points to the entity for the task
3783 -- task body procedure (as further described in Exp_Ch9, task bodies are
3784 -- expanded into procedures). A convenient function to retrieve this
3785 -- field is Sem_Util.Get_Task_Body_Procedure.
3787 -- The last sentence is odd??? Why not have Task_Body_Procedure go to the
3788 -- Underlying_Type of the Root_Type???
3790 -- Treat_As_Volatile (Flag41)
3791 -- Present in all type entities, and also in constants, components and
3792 -- variables. Set if this entity is to be treated as volatile for code
3793 -- generation purposes. Always set if Is_Volatile is set, but can also
3794 -- be set as a result of situations (such as address overlays) where
3795 -- the front end wishes to force volatile handling to inhibit aliasing
3796 -- optimization which might be legally ok, but is undesirable. Note
3797 -- that the back end always tests this flag rather than Is_Volatile.
3798 -- The front end tests Is_Volatile if it is concerned with legality
3799 -- checks associated with declared volatile variables, but if the test
3800 -- is for the purposes of suppressing optimizations, then the front
3801 -- end should test Treat_As_Volatile rather than Is_Volatile.
3803 -- Note: before testing Treat_As_Volatile, consider whether it would
3804 -- be more appropriate to use Exp_Util.Is_Volatile_Reference instead,
3805 -- which catches more cases of volatile references.
3807 -- Type_High_Bound (synthesized)
3808 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
3809 -- the high bound of a scalar type. The returned value is literal for a
3810 -- base type, but may be an expression in the case of scalar type with
3811 -- dynamic bounds. Note that in the case of a fixed point type, the high
3812 -- bound is in units of small, and is an integer.
3814 -- Type_Low_Bound (synthesized)
3815 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
3816 -- the low bound of a scalar type. The returned value is literal for a
3817 -- base type, but may be an expression in the case of scalar type with
3818 -- dynamic bounds. Note that in the case of a fixed point type, the low
3819 -- bound is in units of small, and is an integer.
3821 -- Underlying_Full_View (Node19)
3822 -- Present in private subtypes that are the completion of other private
3823 -- types, or in private types that are derived from private subtypes. If
3824 -- the full view of a private type T is derived from another private type
3825 -- with discriminants Td, the full view of T is also private, and there
3826 -- is no way to attach to it a further full view that would convey the
3827 -- structure of T to the back end. The Underlying_Full_ View is an
3828 -- attribute of the full view that is a subtype of Td with the same
3829 -- constraint as the declaration for T. The declaration for this subtype
3830 -- is built at the point of the declaration of T, either as completion,
3831 -- or as a subtype declaration where the base type is private and has a
3832 -- private completion. If Td is already constrained, then its full view
3833 -- can serve directly as the full view of T.
3835 -- Underlying_Record_View (Node28)
3836 -- Present in record types. Set for record types that are extensions of
3837 -- types with unknown discriminants, and also set for internally built
3838 -- underlying record views to reference its original record type. Record
3839 -- types that are extensions of types with unknown discriminants do not
3840 -- have a completion, but they cannot be used without having some
3841 -- discriminated view at hand. This view is a record type with the same
3842 -- structure, whose parent type is the full view of the parent in the
3843 -- original type extension.
3845 -- Underlying_Type (synthesized)
3846 -- Applies to all entities. This is the identity function except in the
3847 -- case where it is applied to an incomplete or private type, in which
3848 -- case it is the underlying type of the type declared by the completion,
3849 -- or Empty if the completion has not yet been encountered and analyzed.
3851 -- Note: the reason this attribute applies to all entities, and not just
3852 -- types, is to legitimize code where Underlying_Type is applied to an
3853 -- entity which may or may not be a type, with the intent that if it is a
3854 -- type, its underlying type is taken.
3856 -- Universal_Aliasing (Flag216) [base type only]
3857 -- Present in all type entities. Set to direct the back-end to avoid
3858 -- any optimizations based on type-based alias analysis for this type.
3859 -- Indicates that objects of this type can alias objects of any other
3860 -- types, which guarantees that any objects can be referenced through
3861 -- access types designating this type safely, whatever the actual type
3862 -- of these objects. In other words, the effect is as though access
3863 -- types designating this type were subject to No_Strict_Aliasing.
3865 -- Unset_Reference (Node16)
3866 -- Present in variables and out parameters. This is normally Empty. It
3867 -- is set to point to an identifier that represents a reference to the
3868 -- entity before any value has been set. Only the first such reference
3869 -- is identified. This field is used to generate a warning message if
3870 -- necessary (see Sem_Warn.Check_Unset_Reference).
3872 -- Used_As_Generic_Actual (Flag222)
3873 -- Present in all entities, set if the entity is used as an argument to
3874 -- a generic instantiation. Used to tune certain warning messages.
3876 -- Uses_Sec_Stack (Flag95)
3877 -- Present in scope entities (blocks,functions, procedures, tasks,
3878 -- entries). Set to True when secondary stack is used in this scope and
3879 -- must be released on exit unless Sec_Stack_Needed_For_Return is set.
3881 -- Warnings_Off (Flag96)
3882 -- Present in all entities. Set if a pragma Warnings (Off, entity-name)
3883 -- is used to suppress warnings for a given entity. It is also used by
3884 -- the compiler in some situations to kill spurious warnings. Note that
3885 -- clients should generally not test this flag directly, but instead
3886 -- use function Has_Warnings_Off.
3888 -- Warnings_Off_Used (Flag236)
3889 -- Present in all entities. Can only be set if Warnings_Off is set. If
3890 -- set indicates that a warning was suppressed by the Warnings_Off flag,
3891 -- and Unmodified/Unreferenced would not have suppressed the warning.
3893 -- Warnings_Off_Used_Unmodified (Flag237)
3894 -- Present in all entities. Can only be set if Warnings_Off is set and
3895 -- Has_Pragma_Unmodified is not set. If set indicates that a warning was
3896 -- suppressed by the Warnings_Off status but that pragma Unmodified
3897 -- would also have suppressed the warning.
3899 -- Warnings_Off_Used_Unreferenced (Flag238)
3900 -- Present in all entities. Can only be set if Warnings_Off is set and
3901 -- Has_Pragma_Unreferenced is not set. If set indicates that a warning
3902 -- was suppressed by the Warnings_Off status but that pragma Unreferenced
3903 -- would also have suppressed the warning.
3905 -- Was_Hidden (Flag196)
3906 -- Present in all entities. Used to save the value of the Is_Hidden
3907 -- attribute when the limited-view is installed (Ada 2005: AI-217).
3909 -- Wrapped_Entity (Node27)
3910 -- Present in functions and procedures which have been classified as
3911 -- Is_Primitive_Wrapper. Set to the entity being wrapper.
3913 --------------------------------------
3914 -- Delayed Freezing and Elaboration --
3915 --------------------------------------
3917 -- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
3918 -- freeze node, which appears later in the expanded tree.
3920 -- a) The flag is used by the front-end to trigger expansion actions
3921 -- which include the generation of that freeze node. Typically this happens at
3922 -- the end of the current compilation unit, or before the first subprogram
3923 -- body is encountered in the current unit. See files freeze and exp_ch13 for
3924 -- details on the actions triggered by a freeze node, which include the
3925 -- construction of initialization procedures and dispatch tables.
3927 -- b) The flag is used by the backend to defer elaboration of the entity until
3928 -- its freeze node is seen. In the absence of an explicit freeze node, an
3929 -- entity is frozen (and elaborated) at the point of declaration.
3931 -- For object declarations, the flag is set when an address clause for the
3932 -- object is encountered. Legality checks on the address expression only
3933 -- take place at the freeze point of the object.
3935 -- Most types have an explicit freeze node, because they cannot be elaborated
3936 -- until all representation and operational items that apply to them have been
3937 -- analyzed. Private types and incomplete types have the flag set as well, as
3938 -- do task and protected types.
3940 -- Implicit base types created for type derivations, as well as classwide
3941 -- types created for all tagged types, have the flag set.
3943 -- If a subprogram has an access parameter whose designated type is incomplete
3944 -- the subprogram has the flag set.

3954 -- E_General_Access_Type,
3955 -- E_Access_Subprogram_Type,
3956 -- E_Anonymous_Access_Subprogram_Type,
3957 -- E_Access_Protected_Subprogram_Type,
3958 -- E_Anonymous_Access_Protected_Subprogram_Type
3959 -- E_Anonymous_Access_Type.
3961 -- E_Access_Subtype is for an access subtype created by a subtype
3964 -- In addition, we define the kind E_Allocator_Type to label allocators.
3965 -- This is because special resolution rules apply to this construct.
3966 -- Eventually the constructs are labeled with the access type imposed by
3967 -- the context. Gigi should never see the type E_Allocator.
3969 -- Similarly, the type E_Access_Attribute_Type is used as the initial kind
3970 -- associated with an access attribute. After resolution a specific access
3971 -- type will be established as determined by the context.
3973 -- Finally, the type Any_Access is used to label -null- during type
3974 -- resolution. Any_Access is also replaced by the context type after

3978 -- Classification of Entities --
3979 --------------------------------
3981 -- The classification of program entities which follows is a refinement of
3982 -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
3983 -- different type classes. Ada 95 entities include class wide types,
3984 -- protected types, subprogram types, generalized access types, generic
3985 -- formal derived types and generic formal packages.
3987 -- The order chosen for these kinds allows us to classify related entities
3988 -- so that they are contiguous. As a result, they do not appear in the
3989 -- exact same order as their order of first appearance in the LRM (For
3990 -- example, private types are listed before packages). The contiguity
3991 -- allows us to define useful subtypes (see below) such as type entities,
3992 -- overloaded entities, etc.
3994 -- Each entity (explicitly or implicitly declared) has a kind, which is
3995 -- a value of the following type:
3997 type Entity_Kind is (
4000 -- The initial Ekind value for a newly created entity. Also used as the
4001 -- Ekind for Standard_Void_Type, a type entity in Standard used as a
4002 -- dummy type for the return type of a procedure (the reason we create
4003 -- this type is to share the circuits for performing overload resolution
4011 -- Components of a record declaration, private declarations of
4012 -- protected objects.
4015 -- Constants created by an object declaration with a constant keyword

4356 -- A dummy entity created for each return statement. Used to hold
4357 -- information about the return statement (what it applies to) and in

4381 -- A task body. This entity serves almost no function, since all
4382 -- semantic analysis uses the protected entity (E_Task_Type).
4385 -- A subprogram body. Used when a subprogram has a separate declaration
4386 -- to represent the entity for the body. This entity serves almost no

5781 -- Since E_Void is the initial Ekind value of an entity when it is first

5784 -- are many instances in which fields of an E_Void entity are set in the
5785 -- code prior to setting the Ekind field. This is not well documented or
5786 -- well controlled, and needs cleaning up later. Meanwhile, the access
5787 -- procedures in the body of Einfo permit many, but not all, attributes
5788 -- to be applied to an E_Void entity, precisely so that this kind of
5789 -- pre-setting of attributes works. This is really a hole in the dynamic
5790 -- type checking, since there is no assurance that the eventual Ekind

5796 -- Component_Alignment Control --
5797 ---------------------------------
5799 -- There are four types of alignment possible for array and record
5800 -- types, and a field in the type entities contains a value of the
5801 -- following type indicating which alignment choice applies. For full
5802 -- details of the meaning of these alignment types, see description
5803 -- of the Component_Alignment pragma
5805 type Component_Alignment_Kind is (
5806 Calign_Default, -- default alignment
5807 Calign_Component_Size, -- natural alignment for component size
5808 Calign_Component_Size_4, -- natural for size <= 4, 4 for size >= 4
5809 Calign_Storage_Unit); -- all components byte aligned
5811 -----------------------------------
5812 -- Floating Point Representation --
5813 -----------------------------------
5815 type Float_Rep_Kind is (
5816 IEEE_Binary, -- IEEE 754p conform binary format
5817 VAX_Native, -- VAX D, F, G or H format
5818 AAMP); -- AAMP format
5824 -- In addition to attributes that are stored as plain data, other
5825 -- attributes are procedural, and require some small amount of
5826 -- computation. Of course, from the point of view of a user of this
5827 -- package, the distinction is not visible (even the field information
5828 -- provided below should be disregarded, as it is subject to change
5829 -- without notice!). A number of attributes appear as lists: lists of
5830 -- formals, lists of actuals, of discriminants, etc. For these, pairs
5831 -- of functions are defined, which take the form:
5833 -- function First_Thing (E : Enclosing_Construct) return Thing;
5834 -- function Next_Thing (T : Thing) return Thing;
5836 -- The end of iteration is always signaled by a value of Empty, so that
5837 -- loops over these chains invariably have the form:
5841 -- This := First_Thing (E);
5843 -- while Present (This) loop
5844 -- Do_Something_With (This);
5846 -- This := Next_Thing (This);

5850 -- Handling of Check Suppression --
5851 -----------------------------------
5853 -- There are three ways that checks can be suppressed:
5855 -- 1. At the command line level
5856 -- 2. At the scope level.
5857 -- 3. At the entity level.
5859 -- See spec of Sem in sem.ads for details of the data structures used
5860 -- to keep track of these various methods for suppressing checks.
5862 -------------------------------
5863 -- Handling of Discriminants --
5864 -------------------------------
5866 -- During semantic processing, discriminants are separate entities which
5867 -- reflect the semantic properties and allowed usage of discriminants in
5870 -- In the case of discriminants used as bounds, the references are handled
5871 -- directly, since special processing is needed in any case. However, there
5872 -- are two circumstances in which discriminants are referenced in a quite
5873 -- general manner, like any other variables:
5875 -- In initialization expressions for records. Note that the expressions
5876 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline
5877 -- pragmas are effectively in this category, since these pragmas are
5878 -- converted to initialized record fields in the Corresponding_Record_
5881 -- In task and protected bodies, where the discriminant values may be
5882 -- referenced freely within these bodies. Discriminants can also appear
5883 -- in bounds of entry families and in defaults of operations.
5885 -- In both these cases, the discriminants must be treated essentially as
5886 -- objects. The following approach is used to simplify and minimize the
5887 -- special processing that is required.
5889 -- When a record type with discriminants is analyzed, semantic processing
5890 -- creates the entities for the discriminants. It also creates additional
5891 -- sets of entities called discriminals, one for each of the discriminants,
5892 -- and the Discriminal field of the discriminant entity points to this
5893 -- additional entity, which is initially created as an uninitialized
5896 -- During expansion of expressions, any discriminant reference is replaced
5897 -- by a reference to the corresponding discriminal. When the initialization
5898 -- procedure for the record is created (there will always be one, since
5899 -- discriminants are present, see Exp_Ch3 for further details), the
5900 -- discriminals are used as the entities for the formal parameters of
5901 -- this initialization procedure. The references to these discriminants
5902 -- have already been replaced by references to these discriminals, which
5903 -- are now the formal parameters corresponding to the required objects.
5905 -- In the case of a task or protected body, the semantics similarly creates
5906 -- a set of discriminals for the discriminants of the task or protected
5907 -- type. When the procedure is created for the task body, the parameter
5908 -- passed in is a reference to the task value type, which contains the
5909 -- required discriminant values. The expander creates a set of declarations
5912 -- discr_nameD : constant discr_type renames _task.discr_name;
5914 -- where discr_nameD is the discriminal entity referenced by the task
5915 -- discriminant, and _task is the task value passed in as the parameter.
5916 -- Again, any references to discriminants in the task body have been
5917 -- replaced by the discriminal reference, which is now an object that
5918 -- contains the required value.
5920 -- This approach for tasks means that two sets of discriminals are needed
5921 -- for a task type, one for the initialization procedure, and one for the
5922 -- task body. This works out nicely, since the semantics allocates one set
5923 -- for the task itself, and one set for the corresponding record.
5925 -- The one bit of trickiness arises in making sure that the right set of
5926 -- discriminals is used at the right time. First the task definition is
5927 -- processed. Any references to discriminants here are replaced by the
5928 -- corresponding *task* discriminals (the record type doesn't even exist
5929 -- yet, since it is constructed as part of the expansion of the task
5930 -- declaration, which happens after the semantic processing of the task
5931 -- definition). The discriminants to be used for the corresponding record
5932 -- are created at the same time as the other discriminals, and held in the
5933 -- CR_Discriminant field of the discriminant. A use of the discriminant in
5934 -- a bound for an entry family is replaced with the CR_Discriminant because
5935 -- it controls the bound of the entry queue array which is a component of
5936 -- the corresponding record.
5938 -- Just before the record initialization routine is constructed, the
5939 -- expander exchanges the task and record discriminals. This has two
5940 -- effects. First the generation of the record initialization routine
5941 -- uses the discriminals that are now on the record, which is the set
5942 -- that used to be on the task, which is what we want.
5944 -- Second, a new set of (so far unused) discriminals is now on the task
5945 -- discriminants, and it is this set that will be used for expanding the
5946 -- task body, and also for the discriminal declarations at the start of
5949 ---------------------------------------------------
5950 -- Handling of private data in protected objects --
5951 ---------------------------------------------------
5953 -- Private components in protected types pose problems similar to those
5954 -- of discriminants. Private data is visible and can be directly referenced
5955 -- from protected bodies. However, when protected entries and subprograms
5956 -- are expanded into corresponding bodies and barrier functions, private
5957 -- components lose their original context and visibility.
5959 -- To remedy this side effect of expansion, private components are expanded
5960 -- into renamings called "privals", by analogy with "discriminals".
5962 -- private_comp : comp_type renames _object.private_comp;
5964 -- Prival declarations are inserted during the analysis of subprogram and
5965 -- entry bodies to ensure proper visibility for any subsequent expansion.
5966 -- _Object is the formal parameter of the generated corresponding body or
5967 -- a local renaming which denotes the protected object obtained from entry
5968 -- parameter _O. Privals receive minimal decoration upon creation and are
5969 -- categorized as either E_Variable for the general case or E_Constant when
5970 -- they appear in functions.
5972 -- Along with the local declarations, each private component carries a
5973 -- placeholder which references the prival entity in the current body. This
5974 -- form of indirection is used to resolve name clashes of privals and other
5975 -- locally visible entities such as parameters, local objects, entry family
5976 -- indexes or identifiers used in the barrier condition.
5978 -- When analyzing the statements of a protected subprogram or entry, any
5979 -- reference to a private component must resolve to the locally declared
5980 -- prival through normal visibility. In case of name conflicts (the cases
5981 -- above), the prival is marked as hidden and acts as a weakly declared
5982 -- entity. As a result, the reference points to the correct entity. When a
5983 -- private component is denoted by an expanded name (prot_type.comp for
5984 -- example), the expansion mechanism uses the placeholder of the component
5985 -- to correct the Entity and Etype of the reference.
5991 -- The following type synonyms are used to tidy up the function and
5992 -- procedure declarations that follow, and also to make it possible to meet
5993 -- the requirement for the XEINFO utility that all function specs must fit
5994 -- on a single source line.

6543 -- These predicates test the setting of the indicated attribute. If the
6544 -- value has been set, then Known is True, and Unknown is False. If no
6545 -- value is set, then Known is False and Unknown is True. The Known_Static
6546 -- predicate is true only if the value is set (Known) and is set to a
6547 -- compile time known value. Note that in the case of Alignment and
6548 -- Normalized_First_Bit, dynamic values are not possible, so we do not
6549 -- need a separate Known_Static calls in these cases. The not set (unknown)
6550 -- values are as follows:
6552 -- Alignment Uint_0 or No_Uint
6553 -- Component_Size Uint_0 or No_Uint
6554 -- Component_Bit_Offset No_Uint
6555 -- Digits_Value Uint_0 or No_Uint
6556 -- Esize Uint_0 or No_Uint
6557 -- Normalized_First_Bit No_Uint
6558 -- Normalized_Position No_Uint
6559 -- Normalized_Position_Max No_Uint
6560 -- RM_Size Uint_0 or No_Uint
6562 -- It would be cleaner to use No_Uint in all these cases, but historically
6563 -- we chose to use Uint_0 at first, and the change over will take time ???
6564 -- This is particularly true for the RM_Size field, where a value of zero
6565 -- is legitimate. We deal with this by a nasty kludge that knows that the
6566 -- value is always known static for discrete types (and no other types can
6567 -- have an RM_Size value of zero).
6569 -- In two cases, Known_Static_Esize and Known_Static_RM_Size, there is one
6570 -- more consideration, which is that we always return False for generic
6571 -- types. Within a template, the size can look known, because of the fake
6572 -- size values we put in template types, but they are not really known and
6573 -- anyone testing if they are known within the template should get False as
6574 -- a result to prevent incorrect assumptions.
