39 -- This package defines the annotations to the abstract syntax tree that
40 -- are needed to support semantic processing of an Ada compilation.
42 -- Note that after editing this spec and the corresponding body it is
43 -- required to run ceinfo to check the consistentcy of spec and body.
44 -- See ceinfo.adb for more information about the checks made.
46 -- These annotations are for the most part attributes of declared entities,
47 -- and they correspond to conventional symbol table information. Other
48 -- attributes include sets of meanings for overloaded names, possible
49 -- types for overloaded expressions, flags to indicate deferred constants,
50 -- incomplete types, etc. These attributes are stored in available fields in
51 -- tree nodes (i.e. fields not used by the parser, as defined by the Sinfo
52 -- package specification), and accessed by means of a set of subprograms
53 -- which define an abstract interface.
55 -- There are two kinds of semantic information
57 -- First, the tree nodes with the following Nkind values:
59 -- N_Defining_Identifier
60 -- N_Defining_Character_Literal
61 -- N_Defining_Operator_Symbol
63 -- are called Entities, and constitute the information that would often
64 -- be stored separately in a symbol table. These nodes are all extended
65 -- to provide extra space, and contain fields which depend on the entity
66 -- kind, as defined by the contents of the Ekind field. The use of the
67 -- Ekind field, and the associated fields in the entity, are defined
68 -- in this package, as are the access functions to these fields.
70 -- Second, in some cases semantic information is stored directly in other
71 -- kinds of nodes, e.g. the Etype field, used to indicate the type of an
72 -- expression. The access functions to these fields are defined in the
73 -- Sinfo package, but their full documentation is to be found in
74 -- the Einfo package specification.
76 -- Declaration processing places information in the nodes of their defining
77 -- identifiers. Name resolution places in all other occurrences of an
78 -- identifier a pointer to the corresponding defining occurrence.
80 --------------------------------
81 -- The XEINFO Utility Program --
82 --------------------------------
84 -- XEINFO is a utility program which automatically produces a C header file,
85 -- einfo.h from the spec and body of package Einfo. It reads the input files
86 -- einfo.ads and einfo.adb and produces the output file einfo.h. XEINFO is run
87 -- automatically by the build scripts when you do a full bootstrap.
89 -- In order for this utility program to operate correctly, the form of the
90 -- einfo.ads and einfo.adb files must meet certain requirements and be laid
91 -- out in a specific manner.
93 -- The general form of einfo.ads is as follows:
95 -- type declaration for type Entity_Kind
96 -- subtype declarations declaring subranges of Entity_Kind
97 -- subtype declarations declaring synonyms for some standard types
98 -- function specs for attributes
100 -- pragma Inline declarations
102 -- This order must be observed. There are no restrictions on the procedures,
103 -- since the C header file only includes functions (The back end is not
104 -- allowed to modify the generated tree). However, functions are required to
105 -- have headers that fit on a single line.
107 -- XEINFO reads and processes the function specs and the pragma Inlines. For
108 -- functions that are declared as inlined, XEINFO reads the corresponding body
109 -- from einfo.adb, and processes it into C code. This results in some strict
110 -- restrictions on which functions can be inlined:
112 -- The function spec must be on a single line
114 -- There can only be a single statement, contained on a single line,
115 -- not counting any pragma Assert statements.
117 -- This single statement must either be a function call with simple,
118 -- single token arguments, or it must be a membership test of the form
119 -- a in b, where a and b are single tokens.
121 -- For functions that are not inlined, there is no restriction on the body,
122 -- and XEINFO generates a direct reference in the C header file which allows
123 -- the C code in the backend to directly call the corresponding Ada body.
125 ----------------------------------
126 -- Handling of Type'Size Values --
127 ----------------------------------
129 -- The Ada 95 RM contains some rather peculiar (to us) rules on the value
130 -- of type'Size (see RM 13.3(55)). We have found that attempting to use
131 -- these RM Size values generally, and in particular for determining the
132 -- default size of objects, creates chaos, and major incompatibilities in
135 -- We proceed as follows, for discrete and fixed-point subtypes, we have
136 -- two separate sizes for each subtype:
138 -- The Object_Size, which is used for determining the default size of
139 -- objects and components. This size value can be referred to using the
140 -- Object_Size attribute. The phrase "is used" here means that it is
141 -- the basis of the determination of the size. The backend is free to
142 -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
143 -- character might be stored in 32 bits on a machine with no efficient
144 -- byte access instructions such as the Alpha.
146 -- The default rules for the value of Object_Size for fixed-point and
147 -- discrete types are as follows:
149 -- The Object_Size for base subtypes reflect the natural hardware
150 -- size in bits (see Ttypes and Cstand for integer types). For
151 -- enumeration and fixed-point base subtypes have 8, 16, 32, or 64
152 -- bits for this size, depending on the range of values to be stored.
154 -- The Object_Size of a subtype is the same as the Object_Size of
155 -- the subtype from which it is obtained.
157 -- The Object_Size of a derived base type is copied from the parent
158 -- base type, and the Object_Size of a derived first subtype is copied
159 -- from the parent first subtype.
161 -- The Value_Size which is the number of bits required to store a value
162 -- of the type. This size can be referred to using the Value_Size
163 -- attribute. This value is used to determine how tightly to pack
164 -- records or arrays with components of this type, and also affects
165 -- the semantics of unchecked conversion (unchecked conversions where
166 -- the Value_Size values differ generate a warning, and are potentially
167 -- target dependent).
169 -- The default rules for the value of Value_Size are as follows:
171 -- The Value_Size for a base subtype is the minimum number of bits
172 -- required to store all values of the type (including the sign bit
173 -- only if negative values are possible).
175 -- If a subtype statically matches the first subtype, then it has
176 -- by default the same Value_Size as the first subtype. This is a
177 -- consequence of RM 13.1(14) ("if two subtypes statically match,
178 -- then their subtype-specific aspects are the same".)
180 -- All other subtypes have a Value_Size corresponding to the minimum
181 -- number of bits required to store all values of the subtype. For
182 -- dynamic bounds, it is assumed that the value can range down or up
183 -- to the corresponding bound of the ancestor.
185 -- The RM defined attribute Size corresponds to the Value_Size attribute.
187 -- The Size attribute may be defined for a first-named subtype. This sets
188 -- the Value_Size of the first-named subtype to the given value, and the
189 -- Object_Size of this first-named subtype to the given value padded up
190 -- to an appropriate boundary. It is a consequence of the default rules
191 -- above that this Object_Size will apply to all further subtypes. On the
192 -- other hand, Value_Size is affected only for the first subtype, any
193 -- dynamic subtypes obtained from it directly, and any statically matching
194 -- subtypes. The Value_Size of any other static subtypes is not affected.
196 -- Value_Size and Object_Size may be explicitly set for any subtype using
197 -- an attribute definition clause. Note that the use of these attributes
198 -- can cause the RM 13.1(14) rule to be violated. If two access types
199 -- reference aliased objects whose subtypes have differing Object_Size
200 -- values as a result of explicit attribute definition clauses, then it
201 -- is erroneous to convert from one access subtype to the other.
203 -- At the implementation level, Esize stores the Object_Size and the
204 -- RM_Size field stores the Value_Size (and hence the value of the
205 -- Size attribute, which, as noted above, is equivalent to Value_Size).
207 -- To get a feel for the difference, consider the following examples (note
208 -- that in each case the base is short_short_integer with a size of 8):
210 -- Object_Size Value_Size
212 -- type x1 is range 0..5; 8 3
214 -- type x2 is range 0..5;
215 -- for x2'size use 12; 16 12
217 -- subtype x3 is x2 range 0 .. 3; 16 2
219 -- subtype x4 is x2'base range 0 .. 10; 8 4
221 -- dynamic : x2'Base range -64 .. +63;
223 -- subtype x5 is x2 range 0 .. dynamic; 16 3*
225 -- subtype x6 is x2'base range 0 .. dynamic; 8 7*
227 -- Note: the entries marked * are not actually specified by the Ada 95 RM,
228 -- but it seems in the spirit of the RM rules to allocate the minimum number
229 -- of bits known to be large enough to hold the given range of values.
231 -- So far, so good, but GNAT has to obey the RM rules, so the question is
232 -- under what conditions must the RM Size be used. The following is a list
233 -- of the occasions on which the RM Size must be used:
235 -- Component size for packed arrays or records
236 -- Value of the attribute Size for a type
237 -- Warning about sizes not matching for unchecked conversion
239 -- The RM_Size field keeps track of the RM Size as needed in these
242 -- For elementary types other than discrete and fixed-point types, the
243 -- Object_Size and Value_Size are the same (and equivalent to the RM
244 -- attribute Size). Only Size may be specified for such types.
246 -- For composite types, Object_Size and Value_Size are computed from their
247 -- respective value for the type of each element as well as the layout.
249 -- All size attributes are stored as Uint values. Negative values are used to
250 -- reference GCC expressions for the case of non-static sizes, as explained
253 --------------------------------------
254 -- Delayed Freezing and Elaboration --
255 --------------------------------------
257 -- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
258 -- freeze node, which appears later in the expanded tree.
260 -- a) The flag is used by the front-end to trigger expansion actions which
261 -- include the generation of that freeze node. Typically this happens at the
262 -- end of the current compilation unit, or before the first subprogram body is
263 -- encountered in the current unit. See files freeze and exp_ch13 for details
264 -- on the actions triggered by a freeze node, which include the construction
265 -- of initialization procedures and dispatch tables.
267 -- b) The presence of a freeze node on an entity is used by the backend to
268 -- defer elaboration of the entity until its freeze node is seen. In the
269 -- absence of an explicit freeze node, an entity is frozen (and elaborated)
270 -- at the point of declaration.
272 -- For object declarations, the flag is set when an address clause for the
273 -- object is encountered. Legality checks on the address expression only take
274 -- place at the freeze point of the object.
276 -- Most types have an explicit freeze node, because they cannot be elaborated
277 -- until all representation and operational items that apply to them have been
278 -- analyzed. Private types and incomplete types have the flag set as well, as
279 -- do task and protected types.
281 -- Implicit base types created for type derivations, as well as classwide
282 -- types created for all tagged types, have the flag set.
284 -- If a subprogram has an access parameter whose designated type is incomplete
285 -- the subprogram has the flag set.
287 -----------------------
288 -- Entity Attributes --
289 -----------------------
291 -- This section contains a complete list of the attributes that are defined
292 -- on entities. Some attributes apply to all entities, others only to certain
293 -- kinds of entities. In the latter case the attribute should only be set or
294 -- accessed if the Ekind field indicates an appropriate entity.
296 -- There are two kinds of attributes that apply to entities, stored and
297 -- synthesized. Stored attributes correspond to a field or flag in the entity
298 -- itself. Such attributes are identified in the table below by giving the
299 -- field or flag in the attribute that is used to hold the attribute value.
300 -- Synthesized attributes are not stored directly, but are rather computed as
301 -- needed from other attributes, or from information in the tree. These are
302 -- marked "synthesized" in the table below. The stored attributes have both
303 -- access functions and set procedures to set the corresponding values, while
304 -- synthesized attributes have only access functions.
306 -- Note: in the case of Node, Uint, or Elist fields, there are cases where the
307 -- same physical field is used for different purposes in different entities,
308 -- so these access functions should only be referenced for the class of
309 -- entities in which they are defined as being present. Flags are not
310 -- overlapped in this way, but nevertheless as a matter of style and
311 -- abstraction (which may or may not be checked by assertions in the
312 -- body), this restriction should be observed for flag fields as well.
314 -- Note: certain of the attributes on types apply only to base types, and
315 -- are so noted by the notation [base type only]. These are cases where the
316 -- attribute of any subtype is the same as the attribute of the base type.
317 -- The attribute can be referenced on a subtype (and automatically retrieves
318 -- the value from the base type). However, it is an error to try to set the
319 -- attribute on other than the base type, and if assertions are enabled,
320 -- an attempt to set the attribute on a subtype will raise an assert error.
322 -- Other attributes are noted as applying to the [implementation base type
323 -- only]. These are representation attributes which must always apply to a
324 -- full non-private type, and where the attributes are always on the full
325 -- type. The attribute can be referenced on a subtype (and automatically
326 -- retrieves the value from the implementation base type). However, it is an
327 -- error to try to set the attribute on other than the implementation base
328 -- type, and if assertions are enabled, an attempt to set the attribute on a
329 -- subtype will raise an assert error.
331 -- Abstract_States (Elist25)
332 -- Defined for E_Package entities. Contains a list of all the abstract
333 -- states declared by the related package.
335 -- Accept_Address (Elist21)
336 -- Defined in entries. If an accept has a statement sequence, then an
337 -- address variable is created, which is used to hold the address of the
338 -- parameters, as passed by the runtime. Accept_Address holds an element
339 -- list which represents a stack of entities for these address variables.
340 -- The current entry is the top of the stack, which is the last element
341 -- on the list. A stack is required to handle the case of nested select
342 -- statements referencing the same entry.
344 -- Access_Disp_Table (Elist16) [implementation base type only]
345 -- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged
346 -- types to point to their dispatch tables. The first two entities are
347 -- associated with the primary dispatch table: 1) primary dispatch table
348 -- with user-defined primitives 2) primary dispatch table with predefined
349 -- primitives. For each interface type covered by the tagged type we also
350 -- have: 3) secondary dispatch table with thunks of primitives covering
351 -- user-defined interface primitives, 4) secondary dispatch table with
352 -- thunks of predefined primitives, 5) secondary dispatch table with user
353 -- defined primitives, and 6) secondary dispatch table with predefined
354 -- primitives. The last entity of this list is an access type declaration
355 -- used to expand dispatching calls through the primary dispatch table.
356 -- For an untagged record, contains No_Elist.
358 -- Access_Disp_Table_Elab_Flag (Node30) [implementation base type only]
359 -- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged
360 -- types whose dispatch table elaboration must be completed at run time
361 -- by the IP routine to point to its pending elaboration flag entity.
362 -- This flag is needed when the elaboration of the dispatch table relies
363 -- on attribute 'Position applied to an object of the type; it is used by
364 -- the IP routine to avoid performing this elaboration twice.
366 -- Activation_Record_Component (Node31)
367 -- Defined for E_Variable, E_Constant, E_Loop_Parameter, and formal
368 -- parameter entities. Used in Opt.Unnest_Subprogram_Mode, in which case
369 -- a reference to an uplevel entity produces a corresponding component
370 -- in the generated ARECnT activation record (Exp_Unst for details).
372 -- Actual_Subtype (Node17)
373 -- Defined in variables, constants, and formal parameters. This is the
374 -- subtype imposed by the value of the object, as opposed to its nominal
375 -- subtype, which is imposed by the declaration. The actual subtype
376 -- differs from the nominal one when the latter is indefinite (as in the
377 -- case of an unconstrained formal parameter, or a variable declared
378 -- with an unconstrained type and an initial value). The nominal subtype
379 -- is the Etype entry for the entity. The Actual_Subtype field is set
380 -- only if the actual subtype differs from the nominal subtype. If the
381 -- actual and nominal subtypes are the same, then the Actual_Subtype
382 -- field is Empty, and Etype indicates both types.
384 -- For objects, the Actual_Subtype is set only if this is a discriminated
385 -- type. For arrays, the bounds of the expression are obtained and the
386 -- Etype of the object is directly the constrained subtype. This is
387 -- rather irregular, and the semantic checks that depend on the nominal
388 -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
390 -- Address_Clause (synthesized)
391 -- Applies to entries, objects and subprograms. Set if an address clause
392 -- is present which references the object or subprogram and points to
393 -- the N_Attribute_Definition_Clause node. Empty if no Address clause.
394 -- The expression in the address clause is always a constant that is
395 -- defined before the entity to which the address clause applies.
396 -- Note: The backend references this field in E_Task_Type entities???
398 -- Address_Taken (Flag104)
399 -- Defined in all entities. Set if the Address or Unrestricted_Access
400 -- attribute is applied directly to the entity, i.e. the entity is the
401 -- entity of the prefix of the attribute reference. Also set if the
402 -- entity is the second argument of an Asm_Input or Asm_Output attribute,
403 -- as the construct may entail taking its address. And also set if the
404 -- entity is a subprogram and the Access or Unchecked_Access attribute is
405 -- applied. Used by the backend to make sure that the address can be
406 -- meaningfully taken, and also in the case of subprograms to control
407 -- output of certain warnings.
409 -- Aft_Value (synthesized)
410 -- Applies to fixed and decimal types. Computes a universal integer that
411 -- holds value of the Aft attribute for the type.
414 -- Defined in overloadable entities (literals, subprograms, entries) and
415 -- subprograms that cover a primitive operation of an abstract interface
416 -- (that is, subprograms with the Interface_Alias attribute). In case of
417 -- overloaded entities it points to the parent subprogram of a derived
418 -- subprogram. In case of abstract interface subprograms it points to the
419 -- subprogram that covers the abstract interface primitive. Also used for
420 -- a subprogram renaming, where it points to the renamed subprogram. For
421 -- an inherited operation (of a type extension) that is overridden in a
422 -- private part, the Alias is the overriding operation. In this fashion a
423 -- call from outside the package ends up executing the new body even if
424 -- non-dispatching, and a call from inside calls the overriding operation
425 -- because it hides the implicit one. Alias is always empty for entries.
427 -- Alignment (Uint14)
428 -- Defined in entities for types and also in constants, variables
429 -- (including exceptions where it refers to the static data allocated for
430 -- an exception), loop parameters, and formal parameters. This indicates
431 -- the desired alignment for a type, or the actual alignment for an
432 -- object. A value of zero (Uint_0) indicates that the alignment has not
433 -- been set yet. The alignment can be set by an explicit alignment
434 -- clause, or set by the front-end in package Layout, or set by the
435 -- back-end as part of the back-end back-annotation process. The
436 -- alignment field is also defined in E_Exception entities, but there it
437 -- is used only by the back-end for back annotation.
439 -- Alignment_Clause (synthesized)
440 -- Applies to all entities for types and objects. If an alignment
441 -- attribute definition clause is present for the entity, then this
442 -- function returns the N_Attribute_Definition clause that specifies the
443 -- alignment. If no alignment clause applies to the type, then the call
444 -- to this function returns Empty. Note that the call can return a
445 -- non-Empty value even if Has_Alignment_Clause is not set (happens with
446 -- subtype and derived type declarations). Note also that a record
447 -- definition clause with an (obsolescent) mod clause is converted
448 -- into an attribute definition clause for this purpose.
450 -- Anonymous_Designated_Type (Node35)
451 -- Defined in variables which represent anonymous finalization masters.
452 -- Contains the designated type which is being serviced by the master.
454 -- Anonymous_Masters (Elist29)
455 -- Defined in packages, subprograms, and subprogram bodies. Contains a
456 -- list of anonymous finalization masters declared within the related
457 -- unit. The list acts as a mapping between a master and a designated
460 -- Anonymous_Object (Node30)
461 -- Present in protected and task type entities. Contains the entity of
462 -- the anonymous object created for a single protected or task type.
464 -- Associated_Entity (Node37)
465 -- Defined in all entities. This field is similar to Associated_Node, but
466 -- applied to entities. The attribute links an entity from the generic
467 -- template with its corresponding entity in the analyzed generic copy.
468 -- The global references mechanism relies on the Associated_Entity to
469 -- infer the context.
471 -- Associated_Formal_Package (Node12)
472 -- Defined in packages that are the actuals of formal_packages. Points
473 -- to the entity in the declaration for the formal package.
475 -- Associated_Node_For_Itype (Node8)
476 -- Defined in all type and subtype entities. Set non-Empty only for
477 -- Itypes. Set to point to the associated node for the Itype, i.e.
478 -- the node whose elaboration generated the Itype. This is used for
479 -- copying trees, to determine whether or not to copy an Itype, and
480 -- also for accessibility checks on anonymous access types. This
481 -- node is typically an object declaration, component declaration,
482 -- type or subtype declaration.
484 -- For an access discriminant in a type declaration, the associated_
485 -- node_for_itype is the corresponding discriminant specification.
487 -- For an access parameter it is the enclosing subprogram declaration.
489 -- For an access_to_protected_subprogram parameter it is the declaration
490 -- of the corresponding formal parameter.
492 -- Itypes have no explicit declaration, and therefore are not attached to
493 -- the tree: their Parent field is always empty. The Associated_Node_For_
494 -- Itype is the only way to determine the construct that leads to the
495 -- creation of a given itype entity.
497 -- Associated_Storage_Pool (Node22) [root type only]
498 -- Defined in simple and general access type entities. References the
499 -- storage pool to be used for the corresponding collection. A value of
500 -- Empty means that the default pool is to be used. This is defined
501 -- only in the root type, since derived types must have the same pool
502 -- as the parent type.
504 -- Barrier_Function (Node12)
505 -- Defined in protected entries and entry families. This is the
506 -- subprogram declaration for the body of the function that returns
507 -- the value of the entry barrier.
509 -- Base_Type (synthesized)
510 -- Applies to all type and subtype entities. Returns the base type of a
511 -- type or subtype. The base type of a type is the type itself. The base
512 -- type of a subtype is the type that it constrains (which is always
513 -- a type entity, not some other subtype). Note that in the case of a
514 -- subtype of a private type, it is possible for the base type attribute
515 -- to return a private type, even if the subtype to which it applies is
516 -- non-private. See also Implementation_Base_Type. Note: it is allowed to
517 -- apply Base_Type to other than a type, in which case it simply returns
518 -- the entity unchanged.
520 -- Block_Node (Node11)
521 -- Defined in block entities. Points to the identifier in the
522 -- Block_Statement itself. Used when retrieving the block construct
523 -- for finalization purposes, The block entity has an implicit label
524 -- declaration in the enclosing declarative part, and has otherwise
525 -- no direct connection in the tree with the block statement. The
526 -- link is to the identifier (which is an occurrence of the entity)
527 -- and not to the block_statement itself, because the statement may
528 -- be rewritten, e.g. in the process of removing dead code.
530 -- Body_Entity (Node19)
531 -- Defined in package and generic package entities, points to the
532 -- corresponding package body entity if one is present.
534 -- Body_Needed_For_SAL (Flag40)
535 -- Defined in package and subprogram entities that are compilation
536 -- units. Indicates that the source for the body must be included
537 -- when the unit is part of a standalone library.
539 -- Body_Needed_For_Inlining (Flag299)
540 -- Defined in package entities that are compilation units. Used to
541 -- determine whether the body unit needs to be compiled when the
542 -- package declaration appears in the list of units to inline. A body
543 -- is needed for inline processing if the unit declaration contains
544 -- functions that carry pragma Inline or Inline_Always, or if it
545 -- contains a generic unit that requires a body.
547 -- Body_References (Elist16)
548 -- Defined in abstract state entities. Contains an element list of
549 -- references (identifiers) that appear in a package body whose spec
550 -- defines the related state. If the body refines the said state, all
551 -- references on this list are illegal due to the visible refinement.
553 -- BIP_Initialization_Call (Node29)
554 -- Defined in constants and variables whose corresponding declaration
555 -- is wrapped in a transient block and the inital value is provided by
556 -- a build-in-place function call. Contains the relocated build-in-place
557 -- call after the expansion has decoupled the call from the object. This
558 -- attribute is used by the finalization machinery to insert cleanup code
559 -- for all additional transient objects found in the transient block.
561 -- C_Pass_By_Copy (Flag125) [implementation base type only]
562 -- Defined in record types. Set if a pragma Convention for the record
563 -- type specifies convention C_Pass_By_Copy. This convention name is
564 -- treated as identical in all respects to convention C, except that
565 -- if it is specified for a record type, then the C_Pass_By_Copy flag
566 -- is set, and if a foreign convention subprogram has a formal of the
567 -- corresponding type, then the parameter passing mechanism will be
568 -- set to By_Copy (unless specifically overridden by an Import or
571 -- Can_Never_Be_Null (Flag38)
572 -- This flag is defined in all entities. It is set in an object which can
573 -- never have a null value. Set for constant access values initialized to
574 -- a non-null value. This is also set for all access parameters in Ada 83
575 -- and Ada 95 modes, and for access parameters that explicitly exclude
576 -- exclude null in Ada 2005 mode.
578 -- This is used to avoid unnecessary resetting of the Is_Known_Non_Null
579 -- flag for such entities. In Ada 2005 mode, this is also used when
580 -- determining subtype conformance of subprogram profiles to ensure
581 -- that two formals have the same null-exclusion status.
583 -- This is also set on some access types, e.g. the Etype of the anonymous
584 -- access type of a controlling formal.
586 -- Can_Use_Internal_Rep (Flag229) [base type only]
587 -- Defined in Access_Subprogram_Kind nodes. This flag is set by the
588 -- front end and used by the backend. False means that the backend
589 -- must represent the type in the same way as Convention-C types (and
590 -- other foreign-convention types). On many targets, this means that
591 -- the backend will use dynamically generated trampolines for nested
592 -- subprograms. True means that the backend can represent the type in
593 -- some internal way. On the aforementioned targets, this means that the
594 -- backend will not use dynamically generated trampolines. This flag
595 -- must be False if Has_Foreign_Convention is True; otherwise, the front
596 -- end is free to set the policy.
598 -- Setting this False in all cases corresponds to the traditional back
599 -- end strategy, where all access-to-subprogram types are represented the
600 -- same way, independent of the Convention. For further details, see also
601 -- Always_Compatible_Rep in Targparm.
603 -- Efficiency note: On targets that use dynamically generated
604 -- trampolines, False generally favors efficiency of top-level
605 -- subprograms, whereas True generally favors efficiency of nested
606 -- ones. On other targets, this flag has little or no effect on
607 -- efficiency. The front end should take this into account. In
608 -- particular, pragma Favor_Top_Level gives a hint that the flag
611 -- Note: We considered using Convention-C for this purpose, but we need
612 -- this separate flag, because Convention-C implies that in the case of
613 -- P'[Unrestricted_]Access, P also have convention C. Sometimes we want
614 -- to have Can_Use_Internal_Rep False for an access type, but allow P to
615 -- have convention Ada.
618 -- Defined in all entities. This field contains an entry into the names
619 -- table that has the character string of the identifier, character
620 -- literal or operator symbol. See Namet for further details. Note that
621 -- throughout the processing of the front end, this name is the simple
622 -- unqualified name. However, just before the backend is called, a call
623 -- is made to Qualify_All_Entity_Names. This causes entity names to be
624 -- qualified using the encoding described in exp_dbug.ads, and from that
625 -- point (including post backend steps, e.g. cross-reference generation),
626 -- the entities will contain the encoded qualified names.
628 -- Checks_May_Be_Suppressed (Flag31)
629 -- Defined in all entities. Set if a pragma Suppress or Unsuppress
630 -- mentions the entity specifically in the second argument. If this
631 -- flag is set the Global_Entity_Suppress and Local_Entity_Suppress
632 -- tables must be consulted to determine if there actually is an active
633 -- Suppress or Unsuppress pragma that applies to the entity.
635 -- Class_Wide_Clone (Node38)
636 -- Defined on subprogram entities. Set if the subprogram has a class-wide
637 -- ore- or postcondition, and the expression contains calls to other
638 -- primitive funtions of the type. Used to implement properly the
639 -- semantics of inherited operations whose class-wide condition may
640 -- be different from that of the ancestor (See AI012-0195).
642 -- Class_Wide_Type (Node9)
643 -- Defined in all type entities. For a tagged type or subtype, returns
644 -- the corresponding implicitly declared class-wide type. For a
645 -- class-wide type, returns itself. Set to Empty for untagged types.
647 -- Cloned_Subtype (Node16)
648 -- Defined in E_Record_Subtype and E_Class_Wide_Subtype entities.
649 -- Each such entity can either have a Discriminant_Constraint, in
650 -- which case it represents a distinct type from the base type (and
651 -- will have a list of components and discriminants in the list headed by
652 -- First_Entity) or else no such constraint, in which case it will be a
653 -- copy of the base type.
655 -- o Each element of the list in First_Entity is copied from the base
656 -- type; in that case, this field is Empty.
658 -- o The list in First_Entity is shared with the base type; in that
659 -- case, this field points to that entity.
661 -- A record or classwide subtype may also be a copy of some other
662 -- subtype and share the entities in the First_Entity with that subtype.
663 -- In that case, this field points to that subtype.
665 -- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
666 -- this field. Note that this field ONLY appears in subtype entries, not
667 -- in type entries, it is not defined, and it is an error to reference
668 -- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
671 -- This flag appears on all nodes, including entities, and indicates
672 -- that the node was created by the scanner or parser from the original
673 -- source. Thus for entities, it indicates that the entity is defined
674 -- in the original source program.
676 -- Component_Alignment (special field) [base type only]
677 -- Defined in array and record entities. Contains a value of type
678 -- Component_Alignment_Kind indicating the alignment of components.
679 -- Set to Calign_Default normally, but can be overridden by use of
680 -- the Component_Alignment pragma. Note: this field is currently
681 -- stored in a non-standard way, see body for details.
683 -- Component_Bit_Offset (Uint11)
684 -- Defined in record components (E_Component, E_Discriminant). First
685 -- bit position of given component, computed from the first bit and
686 -- position values given in the component clause. A value of No_Uint
687 -- means that the value is not yet known. The value can be set by the
688 -- appearance of an explicit component clause in a record representation
689 -- clause, or it can be set by the front-end in package Layout, or it can
690 -- be set by the backend. By the time backend processing is completed,
691 -- this field is always set. A negative value is used to represent
692 -- a value which is not known at compile time, and must be computed
693 -- at run-time (this happens if fields of a record have variable
694 -- lengths). See package Layout for details of these values.
696 -- Note: Component_Bit_Offset is redundant with respect to the fields
697 -- Normalized_First_Bit and Normalized_Position, and could in principle
698 -- be eliminated, but it is convenient in several situations, including
699 -- use in the backend, to have this redundant field.
701 -- Component_Clause (Node13)
702 -- Defined in record components and discriminants. If a record
703 -- representation clause is present for the corresponding record type a
704 -- that specifies a position for the component, then the Component_Clause
705 -- field of the E_Component entity points to the N_Component_Clause node.
706 -- Set to Empty if no record representation clause was present, or if
707 -- there was no specification for this component.
709 -- Component_Size (Uint22) [implementation base type only]
710 -- Defined in array types. It contains the component size value for
711 -- the array. A value of No_Uint means that the value is not yet set.
712 -- The value can be set by the use of a component size clause, or
713 -- by the front end in package Layout, or by the backend. A negative
714 -- value is used to represent a value which is not known at compile
715 -- time, and must be computed at run-time (this happens if the type
716 -- of the component has a variable length size). See package Layout
717 -- for details of these values.
719 -- Component_Type (Node20) [implementation base type only]
720 -- Defined in array types and string types. References component type.
722 -- Contains_Ignored_Ghost_Code (Flag279)
723 -- Defined in blocks, packages and their bodies, subprograms and their
724 -- bodies. Set if the entity contains any ignored Ghost code in the form
725 -- of declaration, procedure call, assignment statement or pragma.
728 -- Defined in constant, entry, entry family, operator, [generic] package,
729 -- package body, protected type, [generic] subprogram, subprogram body,
730 -- variable and task type entities. Points to the contract of the entity,
731 -- holding various assertion items and data classifiers.
733 -- Contract_Wrapper (Node25)
734 -- Defined in entry and entry family entities. Set only when the entry
735 -- [family] has contract cases, preconditions, and/or postconditions.
736 -- Contains the entity of a wrapper procedure which encapsulates the
737 -- original entry and implements precondition/postcondition semantics.
739 -- Corresponding_Concurrent_Type (Node18)
740 -- Defined in record types that are constructed by the expander to
741 -- represent task and protected types (Is_Concurrent_Record_Type flag
742 -- set). Points to the entity for the corresponding task type or the
745 -- Corresponding_Discriminant (Node19)
746 -- Defined in discriminants of a derived type, when the discriminant is
747 -- used to constrain a discriminant of the parent type. Points to the
748 -- corresponding discriminant in the parent type. Otherwise it is Empty.
750 -- Corresponding_Equality (Node30)
751 -- Defined in function entities for implicit inequality operators.
752 -- Denotes the explicit or derived equality operation that creates
753 -- the implicit inequality. Note that this field is not present in
754 -- other function entities, only in implicit inequality routines,
755 -- where Comes_From_Source is always False.
757 -- Corresponding_Function (Node32)
758 -- Defined on procedures internally built with an extra out parameter
759 -- to return a constrained array type, when Modify_Tree_For_C is set.
760 -- Denotes the function that returns the constrained array type for
761 -- which this procedure was built.
763 -- Corresponding_Procedure (Node32)
764 -- Defined on functions that return a constrained array type, when
765 -- Modify_Tree_For_C is set. Denotes the internally built procedure
766 -- with an extra out parameter created for it.
768 -- Corresponding_Protected_Entry (Node18)
769 -- Defined in subprogram bodies. Set for subprogram bodies that implement
770 -- a protected type entry to point to the entity for the entry.
772 -- Corresponding_Record_Component (Node21)
773 -- Defined in components of a derived untagged record type, including
774 -- discriminants. For a regular component or a girder discriminant,
775 -- points to the corresponding component in the parent type. Set to
776 -- Empty for a non-girder discriminant. It is used by the back end to
777 -- ensure the layout of the derived type matches that of the parent
778 -- type when there is no representation clause on the derived type.
780 -- Corresponding_Record_Type (Node18)
781 -- Defined in protected and task types and subtypes. References the
782 -- entity for the corresponding record type constructed by the expander
783 -- (see Exp_Ch9). This type is used to represent values of the task type.
785 -- Corresponding_Remote_Type (Node22)
786 -- Defined in record types that describe the fat pointer structure for
787 -- Remote_Access_To_Subprogram types. References the original access
788 -- to subprogram type.
790 -- CR_Discriminant (Node23)
791 -- Defined in discriminants of concurrent types. Denotes the homologous
792 -- discriminant of the corresponding record type. The CR_Discriminant is
793 -- created at the same time as the discriminal, and used to replace
794 -- occurrences of the discriminant within the type declaration.
796 -- Current_Use_Clause (Node27)
797 -- Defined in packages and in types. For packages, denotes the use
798 -- package clause currently in scope that makes the package use_visible.
799 -- For types, it denotes the use_type clause that makes the operators of
800 -- the type visible. Used for more precise warning messages on redundant
803 -- Current_Value (Node9)
804 -- Defined in all object entities. Set in E_Variable, E_Constant, formal
805 -- parameters and E_Loop_Parameter entities if we have trackable current
806 -- values. Set non-Empty if the (constant) current value of the variable
807 -- is known, This value is valid only for references from the same
808 -- sequential scope as the entity. The sequential scope of an entity
809 -- includes the immediate scope and any contained scopes that are package
810 -- specs, package bodies, blocks (at any nesting level) or statement
811 -- sequences in IF or loop statements.
813 -- Another related use of this field is to record information about the
814 -- value obtained from an IF or WHILE statement condition. If the IF or
815 -- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ",
816 -- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a
817 -- Current_Value field, RELOP is one of the six relational operators, and
818 -- VAL is a compile-time known value then the Current_Value field of OBJ
819 -- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node
820 -- of the relevant construct, and the Condition field of this can be
821 -- consulted to give information about the value of OBJ. For more details
822 -- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition.
824 -- Debug_Info_Off (Flag166)
825 -- Defined in all entities. Set if a pragma Suppress_Debug_Info applies
826 -- to the entity, or if internal processing in the compiler determines
827 -- that suppression of debug information is desirable. Note that this
828 -- flag is only for use by the front end as part of the processing for
829 -- determining if Needs_Debug_Info should be set. The backend should
830 -- always test Needs_Debug_Info, it should never test Debug_Info_Off.
832 -- Debug_Renaming_Link (Node25)
833 -- Used to link the variable associated with a debug renaming declaration
834 -- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
835 -- details of the use of this field.
837 -- Declaration_Node (synthesized)
838 -- Applies to all entities. Returns the tree node for the construct that
839 -- declared the entity. Normally this is just the Parent of the entity.
840 -- One exception arises with child units, where the parent of the entity
841 -- is a selected component/defining program unit name. Another exception
842 -- is that if the entity is an incomplete type that has been completed or
843 -- a private type, then we obtain the declaration node denoted by the
844 -- full type, i.e. the full type declaration node. Also note that for
845 -- subprograms, this returns the {function,procedure}_specification, not
846 -- the subprogram_declaration.
848 -- Default_Aspect_Component_Value (Node19) [base type only]
849 -- Defined in array types. Holds the static value specified in a
850 -- Default_Component_Value aspect specification for the array type,
851 -- or inherited on derivation.
853 -- Default_Aspect_Value (Node19) [base type only]
854 -- Defined in scalar types. Holds the static value specified in a
855 -- Default_Value aspect specification for the type, or inherited
858 -- Default_Expr_Function (Node21)
859 -- Defined in parameters. It holds the entity of the parameterless
860 -- function that is built to evaluate the default expression if it is
861 -- more complex than a simple identifier or literal. For the latter
862 -- simple cases or if there is no default value, this field is Empty.
864 -- Default_Expressions_Processed (Flag108)
865 -- A flag in subprograms (functions, operators, procedures) and in
866 -- entries and entry families used to indicate that default expressions
867 -- have been processed and to avoid multiple calls to process the
868 -- default expressions (see Freeze.Process_Default_Expressions), which
869 -- would not only waste time, but also generate false error messages.
871 -- Default_Value (Node20)
872 -- Defined in formal parameters. Points to the node representing the
873 -- expression for the default value for the parameter. Empty if the
874 -- parameter has no default value (which is always the case for OUT
875 -- and IN OUT parameters in the absence of errors).
877 -- Delay_Cleanups (Flag114)
878 -- Defined in entities that have finalization lists (subprograms
879 -- blocks, and tasks). Set if there are pending generic body
880 -- instantiations for the corresponding entity. If this flag is
881 -- set, then generation of cleanup actions for the corresponding
882 -- entity must be delayed, since the insertion of the generic body
883 -- may affect cleanup generation (see Inline for further details).
885 -- Delay_Subprogram_Descriptors (Flag50)
886 -- Defined in entities for which exception subprogram descriptors
887 -- are generated (subprograms, package declarations and package
888 -- bodies). Defined if there are pending generic body instantiations
889 -- for the corresponding entity. If this flag is set, then generation
890 -- of the subprogram descriptor for the corresponding enities must
891 -- be delayed, since the insertion of the generic body may add entries
892 -- to the list of handlers.
894 -- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
895 -- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
896 -- a block (in which case Delay_Subprogram_Descriptors is set for the
897 -- containing subprogram). In addition Delay_Subprogram_Descriptors is
898 -- set for a library level package declaration or body which contains
899 -- delayed instantiations (in this case the descriptor refers to the
900 -- enclosing elaboration procedure).
902 -- Delta_Value (Ureal18)
903 -- Defined in fixed and decimal types. Points to a universal real
904 -- that holds value of delta for the type, as given in the declaration
905 -- or as inherited by a subtype or derived type.
907 -- Dependent_Instances (Elist8)
908 -- Defined in packages that are instances. Holds list of instances
909 -- of inner generics. Used to place freeze nodes for those instances
910 -- after that of the current one, i.e. after the corresponding generic
913 -- Depends_On_Private (Flag14)
914 -- Defined in all type entities. Set if the type is private or if it
915 -- depends on a private type.
917 -- Derived_Type_Link (Node31)
918 -- Defined in all type and subtype entries. Set in a base type if
919 -- a derived type declaration is encountered which derives from
920 -- this base type or one of its subtypes, and there are already
921 -- primitive operations declared. In this case, it references the
922 -- entity for the type declared by the derived type declaration.
926 -- subtype RS is R ...
928 -- type G is new RS ...
930 -- In this case, if primitive operations have been declared for R, at
931 -- the point of declaration of G, then the Derived_Type_Link of R is set
932 -- to point to the entity for G. This is used to generate warnings for
933 -- rep clauses that appear later on for R, which might result in an
934 -- unexpected implicit conversion operation.
936 -- Note: if there is more than one such derived type, the link will point
937 -- to the last one (this is only used in generating warning messages).
939 -- Designated_Type (synthesized)
940 -- Applies to access types. Returns the designated type. Differs from
941 -- Directly_Designated_Type in that if the access type refers to an
942 -- incomplete type, and the full type is available, then this full type
943 -- is returned instead of the incomplete type.
945 -- DIC_Procedure (synthesized)
946 -- Defined in all type entities. Set for a private type and its full view
947 -- when the type is subject to pragma Default_Initial_Condition (DIC), or
948 -- when the type inherits a DIC pragma from a parent type. Points to the
949 -- entity of a procedure which takes a single argument of the given type
950 -- and verifies the assertion expression of the DIC pragma at run time.
952 -- Note: the reason this is marked as a synthesized attribute is that the
953 -- way this is stored is as an element of the Subprograms_For_Type field.
955 -- Digits_Value (Uint17)
956 -- Defined in floating point types and subtypes and decimal types and
957 -- subtypes. Contains the Digits value specified in the declaration.
959 -- Direct_Primitive_Operations (Elist10)
960 -- Defined in tagged types and subtypes (including synchronized types),
961 -- in tagged private types and in tagged incomplete types. Element list
962 -- of entities for primitive operations of the tagged type. Not defined
963 -- in untagged types. In order to follow the C++ ABI, entities of
964 -- primitives that come from source must be stored in this list in the
965 -- order of their occurrence in the sources. For incomplete types the
966 -- list is always empty.
967 -- When expansion is disabled the corresponding record type of a
968 -- synchronized type is not constructed. In that case, such types
969 -- carry this attribute directly, for ASIS use.
971 -- Directly_Designated_Type (Node20)
972 -- Defined in access types. This field points to the type that is
973 -- directly designated by the access type. In the case of an access
974 -- type to an incomplete type, this field references the incomplete
975 -- type. Directly_Designated_Type is typically used in implementing the
976 -- static semantics of the language; in implementing dynamic semantics,
977 -- we typically want the full view of the designated type. The function
978 -- Designated_Type obtains this full type in the case of access to an
981 -- Disable_Controlled (Flag253)
982 -- Present in all entities. Set for a controlled type subject to aspect
983 -- Disable_Controlled which evaluates to True. This flag is taken into
984 -- account in synthesized attribute Is_Controlled.
986 -- Discard_Names (Flag88)
987 -- Defined in types and exception entities. Set if pragma Discard_Names
988 -- applies to the entity. It is also set for declarative regions and
989 -- package specs for which a Discard_Names pragma with zero arguments
990 -- has been encountered. The purpose of setting this flag is to be able
991 -- to set the Discard_Names attribute on enumeration types declared
992 -- after the pragma within the same declarative region. This flag is
993 -- set to False if a Keep_Names pragma appears for an enumeration type.
995 -- Discriminal (Node17)
996 -- Defined in discriminants (Discriminant formal: GNAT's first
997 -- coinage). The entity used as a formal parameter that corresponds
998 -- to a discriminant. See section "Handling of Discriminants" for
999 -- full details of the use of discriminals.
1001 -- Discriminal_Link (Node10)
1002 -- Defined in E_In_Parameter or E_Constant entities. For discriminals,
1003 -- points back to corresponding discriminant. For other entities, must
1006 -- Discriminant_Checking_Func (Node20)
1007 -- Defined in components. Points to the defining identifier of the
1008 -- function built by the expander returns a Boolean indicating whether
1009 -- the given record component exists for the current discriminant
1012 -- Discriminant_Constraint (Elist21)
1013 -- Defined in entities whose Has_Discriminants flag is set (concurrent
1014 -- types, subtypes, record types and subtypes, private types and
1015 -- subtypes, limited private types and subtypes and incomplete types).
1016 -- It is an error to reference the Discriminant_Constraint field if
1017 -- Has_Discriminants is False.
1019 -- If the Is_Constrained flag is set, Discriminant_Constraint points
1020 -- to an element list containing the discriminant constraints in the
1021 -- same order in which the discriminants are declared.
1023 -- If the Is_Constrained flag is not set but the discriminants of the
1024 -- unconstrained type have default initial values then this field
1025 -- points to an element list giving these default initial values in
1026 -- the same order in which the discriminants are declared. Note that
1027 -- in this case the entity cannot be a tagged record type, because
1028 -- discriminants in this case cannot have defaults.
1030 -- If the entity is a tagged record implicit type, then this field is
1031 -- inherited from the first subtype (so that the itype is subtype
1032 -- conformant with its first subtype, which is needed when the first
1033 -- subtype overrides primitive operations inherited by the implicit
1036 -- In all other cases Discriminant_Constraint contains the empty
1037 -- Elist (ie it is initialized with a call to New_Elmt_List).
1039 -- Discriminant_Default_Value (Node20)
1040 -- Defined in discriminants. Points to the node representing the
1041 -- expression for the default value of the discriminant. Set to
1042 -- Empty if the discriminant has no default value.
1044 -- Discriminant_Number (Uint15)
1045 -- Defined in discriminants. Gives the ranking of a discriminant in
1046 -- the list of discriminants of the type, i.e. a sequential integer
1047 -- index starting at 1 and ranging up to number of discriminants.
1049 -- Dispatch_Table_Wrappers (Elist26) [implementation base type only]
1050 -- Defined in E_Record_Type and E_Record_Subtype entities. Set in library
1051 -- level tagged type entities if we are generating statically allocated
1052 -- dispatch tables. Points to the list of dispatch table wrappers
1053 -- associated with the tagged type. For an untagged record, contains
1056 -- DTC_Entity (Node16)
1057 -- Defined in function and procedure entities. Set to Empty unless
1058 -- the subprogram is dispatching in which case it references the
1059 -- Dispatch Table pointer Component. For regular Ada tagged this, this
1060 -- is the _Tag component. For CPP_Class types and their descendants,
1061 -- this points to the component entity in the record that holds the
1062 -- Vtable pointer for the Vtable containing the entry referencing the
1065 -- DT_Entry_Count (Uint15)
1066 -- Defined in E_Component entities. Only used for component marked
1067 -- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
1069 -- DT_Offset_To_Top_Func (Node25)
1070 -- Defined in E_Component entities. Only used for component marked
1071 -- Is_Tag. If present it stores the Offset_To_Top function used to
1072 -- provide this value in tagged types whose ancestor has discriminants.
1074 -- DT_Position (Uint15)
1075 -- Defined in function and procedure entities which are dispatching
1076 -- (should not be referenced without first checking that flag
1077 -- Is_Dispatching_Operation is True). Contains the offset into
1078 -- the Vtable for the entry that references the subprogram.
1081 -- Defined in all entities. Contains a value of the enumeration type
1082 -- Entity_Kind declared in a subsequent section in this spec.
1084 -- Elaborate_Body_Desirable (Flag210)
1085 -- Defined in package entities. Set if the elaboration circuitry detects
1086 -- a case where there is a package body that modifies one or more visible
1087 -- entities in the package spec and there is no explicit Elaborate_Body
1088 -- pragma for the package. This information is passed on to the binder,
1089 -- which attempts, but does not promise, to elaborate the body as close
1090 -- to the spec as possible.
1092 -- Elaboration_Entity (Node13)
1093 -- Defined in generic and non-generic package and subprogram entities.
1094 -- This is a counter associated with the unit that is initially set to
1095 -- zero, is incremented when an elaboration request for the unit is
1096 -- made, and is decremented when a finalization request for the unit
1097 -- is made. This is used for three purposes. First, it is used to
1098 -- implement access before elaboration checks (the counter must be
1099 -- non-zero to call a subprogram at elaboration time). Second, it is
1100 -- used to guard against repeated execution of the elaboration code.
1101 -- Third, it is used to ensure that the finalization code is executed
1102 -- only after all clients have requested it.
1104 -- Note that we always allocate this counter, and set this field, but
1105 -- we do not always actually use it. It is only used if it is needed
1106 -- for access before elaboration use (see Elaboration_Entity_Required
1107 -- flag) or if either the spec or the body has elaboration code. If
1108 -- neither of these two conditions holds, then the entity is still
1109 -- allocated (since we don't know early enough whether or not there
1110 -- is elaboration code), but is simply not used for any purpose.
1112 -- Elaboration_Entity_Required (Flag174)
1113 -- Defined in generic and non-generic package and subprogram entities.
1114 -- Set only if Elaboration_Entity is non-Empty to indicate that the
1115 -- counter is required to be non-zero even if there is no other
1116 -- elaboration code. This occurs when the Elaboration_Entity counter
1117 -- is used for access before elaboration checks. If the counter is
1118 -- only used to prevent multiple execution of the elaboration code,
1119 -- then if there is no other elaboration code, obviously there is no
1120 -- need to set the flag.
1122 -- Encapsulating_State (Node32)
1123 -- Defined in abstract state, constant and variable entities. Contains
1124 -- the entity of an ancestor state or a single concurrent type whose
1125 -- refinement utilizes this item as a constituent.
1127 -- Enclosing_Scope (Node18)
1128 -- Defined in labels. Denotes the innermost enclosing construct that
1129 -- contains the label. Identical to the scope of the label, except for
1130 -- labels declared in the body of an accept statement, in which case the
1131 -- entry_name is the Enclosing_Scope. Used to validate goto's within
1132 -- accept statements.
1134 -- Entry_Accepted (Flag152)
1135 -- Defined in E_Entry and E_Entry_Family entities. Set if there is
1136 -- at least one accept for this entry in the task body. Used to
1137 -- generate warnings for missing accepts.
1139 -- Entry_Bodies_Array (Node19)
1140 -- Defined in protected types for which Has_Entries is true.
1141 -- This is the defining identifier for the array of entry body
1142 -- action procedures and barrier functions used by the runtime to
1143 -- execute the user code associated with each entry.
1145 -- Entry_Cancel_Parameter (Node23)
1146 -- Defined in blocks. This only applies to a block statement for
1147 -- which the Is_Asynchronous_Call_Block flag is set. It
1148 -- contains the defining identifier of an object that must be
1149 -- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
1150 -- call in the cleanup handler added to the block by
1151 -- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
1152 -- object for task entry calls and a Communications_Block object
1153 -- in the case of protected entry calls. In both cases the objects
1154 -- are declared in outer scopes to this block.
1156 -- Entry_Component (Node11)
1157 -- Defined in formal parameters (in, in out and out parameters). Used
1158 -- only for formals of entries. References the corresponding component
1159 -- of the entry parameter record for the entry.
1161 -- Entry_Formal (Node16)
1162 -- Defined in components of the record built to correspond to entry
1163 -- parameters. This field points from the component to the formal. It
1164 -- is the back pointer corresponding to Entry_Component.
1166 -- Entry_Index_Constant (Node18)
1167 -- Defined in an entry index parameter. This is an identifier that
1168 -- eventually becomes the name of a constant representing the index
1169 -- of the entry family member whose entry body is being executed. Used
1170 -- to expand references to the entry index specification identifier.
1172 -- Entry_Index_Type (synthesized)
1173 -- Applies to an entry family. Denotes Etype of the subtype indication
1174 -- in the entry declaration. Used to resolve the index expression in an
1175 -- accept statement for a member of the family, and in the prefix of
1176 -- 'COUNT when it applies to a family member.
1178 -- Entry_Max_Queue_Lengths_Array (Node35)
1179 -- Defined in protected types for which Has_Entries is true. Contains the
1180 -- defining identifier for the array of naturals used by the runtime to
1181 -- limit the queue size of each entry individually.
1183 -- Entry_Parameters_Type (Node15)
1184 -- Defined in entries. Points to the access-to-record type that is
1185 -- constructed by the expander to hold a reference to the parameter
1186 -- values. This reference is manipulated (as an address) by the
1187 -- tasking runtime. The designated record represents a packaging
1188 -- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
1189 -- for further details). Entry_Parameters_Type is Empty if the entry
1190 -- has no parameters.
1192 -- Enumeration_Pos (Uint11)
1193 -- Defined in enumeration literals. Contains the position number
1194 -- corresponding to the value of the enumeration literal.
1196 -- Enumeration_Rep (Uint12)
1197 -- Defined in enumeration literals. Contains the representation that
1198 -- corresponds to the value of the enumeration literal. Note that
1199 -- this is normally the same as Enumeration_Pos except in the presence
1200 -- of representation clauses, where Pos will still represent the
1201 -- position of the literal within the type and Rep will have be the
1202 -- value given in the representation clause.
1204 -- Enumeration_Rep_Expr (Node22)
1205 -- Defined in enumeration literals. Points to the expression in an
1206 -- associated enumeration rep clause that provides the representation
1207 -- value for this literal. Empty if no enumeration rep clause for this
1208 -- literal (or if rep clause does not have an entry for this literal,
1209 -- an error situation). This is also used to catch duplicate entries
1210 -- for the same literal.
1212 -- Enum_Pos_To_Rep (Node23)
1213 -- Defined in enumeration types (but not enumeration subtypes). Set to
1214 -- Empty unless the enumeration type has a non-standard representation
1215 -- (i.e. at least one literal has a representation value different from
1216 -- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
1217 -- array constructed when the type is frozen that maps Pos values to
1218 -- corresponding Rep values. The index type of this array is Natural,
1219 -- and the component type is a suitable integer type that holds the
1220 -- full range of representation values.
1222 -- Equivalent_Type (Node18)
1223 -- Defined in class wide types and subtypes, access to protected
1224 -- subprogram types, and in exception types. For a classwide type, it
1225 -- is always Empty. For a class wide subtype, it points to an entity
1226 -- created by the expander which gives the backend an understandable
1227 -- equivalent of the class subtype with a known size (given by an
1228 -- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
1229 -- details. For E_Exception_Type, this points to the record containing
1230 -- the data necessary to represent exceptions (for further details, see
1231 -- System.Standard_Library. For access_to_protected subprograms, it
1232 -- denotes a record that holds pointers to the operation and to the
1233 -- protected object. For remote Access_To_Subprogram types, it denotes
1234 -- the record that is the fat pointer representation of an RAST.
1237 -- Defined in all types and subtypes, and also for components, constants,
1238 -- and variables, including exceptions where it refers to the static data
1239 -- allocated for an exception. Contains the Object_Size of the type or of
1240 -- the object. A value of zero indicates that the value is not yet known.
1242 -- For the case of components where a component clause is present, the
1243 -- value is the value from the component clause, which must be non-
1244 -- negative (but may be zero, which is acceptable for the case of
1245 -- a type with only one possible value). It is also possible for Esize
1246 -- of a component to be set without a component clause defined, which
1247 -- means that the component size is specified, but not the position.
1248 -- See also RM_Size and the section on "Handling of Type'Size Values".
1249 -- During backend processing, the value is back annotated for all zero
1250 -- values, so that after the call to the backend, the value is set.
1253 -- Defined in all entities. Represents the type of the entity, which
1254 -- is itself another entity. For a type entity, points to the parent
1255 -- type for a derived type, or if the type is not derived, points to
1256 -- itself. For a subtype entity, Etype points to the base type. For
1257 -- a class wide type, points to the corresponding specific type. For a
1258 -- subprogram or subprogram type, Etype has the return type of a function
1259 -- or is set to Standard_Void_Type to represent a procedure. The Etype
1260 -- field of a package is also set to Standard_Void_Type.
1262 -- Note one obscure case: for pragma Default_Storage_Pool (null), the
1263 -- Etype of the N_Null node is Empty.
1265 -- Extra_Accessibility (Node13)
1266 -- Defined in formal parameters in the non-generic case. Normally Empty,
1267 -- but if expansion is active, and a parameter is one for which a
1268 -- dynamic accessibility check is required, then an extra formal of type
1269 -- Natural is created (see description of field Extra_Formal), and the
1270 -- Extra_Accessibility field of the formal parameter points to the entity
1271 -- for this extra formal. Also defined in variables when compiling
1272 -- receiving stubs. In this case, a non Empty value means that this
1273 -- variable's accessibility depth has been transmitted by the caller and
1274 -- must be retrieved through the entity designed by this field instead of
1277 -- Extra_Accessibility_Of_Result (Node19)
1278 -- Defined in (non-generic) Function, Operator, and Subprogram_Type
1279 -- entities. Normally Empty, but if expansion is active, and a function
1280 -- is one for which "the accessibility level of the result ... determined
1281 -- by the point of call" (AI05-0234) is needed, then an extra formal of
1282 -- subtype Natural is created (see description of field Extra_Formal),
1283 -- and the Extra_Accessibility_Of_Result field of the function points to
1284 -- the entity for this extra formal.
1286 -- Extra_Constrained (Node23)
1287 -- Defined in formal parameters in the non-generic case. Normally Empty,
1288 -- but if expansion is active and a parameter is one for which a dynamic
1289 -- indication of its constrained status is required, then an extra formal
1290 -- of type Boolean is created (see description of field Extra_Formal),
1291 -- and the Extra_Constrained field of the formal parameter points to the
1292 -- entity for this extra formal. Also defined in variables when compiling
1293 -- receiving stubs. In this case, a non empty value means that this
1294 -- variable's constrained status has been transmitted by the caller and
1295 -- must be retrieved through the entity designed by this field instead of
1298 -- Extra_Formal (Node15)
1299 -- Defined in formal parameters in the non-generic case. Certain
1300 -- parameters require extra implicit information to be passed (e.g. the
1301 -- flag indicating if an unconstrained variant record argument is
1302 -- constrained, and the accessibility level for access parameters). See
1303 -- description of Extra_Constrained, Extra_Accessibility fields for
1304 -- further details. Extra formal parameters are constructed to represent
1305 -- these values, and chained to the end of the list of formals using the
1306 -- Extra_Formal field (i.e. the Extra_Formal field of the last "real"
1307 -- formal points to the first extra formal, and the Extra_Formal field of
1308 -- each extra formal points to the next one, with Empty indicating the
1309 -- end of the list of extra formals). Another case of Extra_Formal arises
1310 -- in connection with unnesting of subprograms, where the ARECnF formal
1311 -- that represents an activation record pointer is an extra formal.
1313 -- Extra_Formals (Node28)
1314 -- Applies to subprograms, subprogram types, entries, and entry
1315 -- families. Returns first extra formal of the subprogram or entry.
1316 -- Returns Empty if there are no extra formals.
1318 -- Finalization_Master (Node23) [root type only]
1319 -- Defined in access-to-controlled or access-to-class-wide types. The
1320 -- field contains the entity of the finalization master which handles
1321 -- dynamically allocated controlled objects referenced by the access
1322 -- type. Empty for access-to-subprogram types. Empty for access types
1323 -- whose designated type does not need finalization actions.
1325 -- Finalize_Storage_Only (Flag158) [base type only]
1326 -- Defined in all types. Set on direct controlled types to which a
1327 -- valid Finalize_Storage_Only pragma applies. This flag is also set on
1328 -- composite types when they have at least one controlled component and
1329 -- all their controlled components are Finalize_Storage_Only. It is also
1330 -- inherited by type derivation except for direct controlled types where
1331 -- the Finalize_Storage_Only pragma is required at each level of
1334 -- Finalizer (Node28)
1335 -- Applies to package declarations and bodies. Contains the entity of the
1336 -- library-level program which finalizes all package-level controlled
1339 -- First_Component (synthesized)
1340 -- Applies to incomplete, private, protected, record and task types.
1341 -- Returns the first component by following the chain of declared
1342 -- entities for the type a component is found (one with an Ekind of
1343 -- E_Component). The discriminants are skipped. If the record is null,
1344 -- then Empty is returned.
1346 -- First_Component_Or_Discriminant (synthesized)
1347 -- Similar to First_Component, but discriminants are not skipped, so will
1348 -- find the first discriminant if discriminants are present.
1350 -- First_Entity (Node17)
1351 -- Defined in all entities which act as scopes to which a list of
1352 -- associated entities is attached (blocks, class subtypes and types,
1353 -- entries, functions, loops, packages, procedures, protected objects,
1354 -- record types and subtypes, private types, task types and subtypes).
1355 -- Points to a list of associated entities using the Next_Entity field
1356 -- as a chain pointer with Empty marking the end of the list.
1358 -- First_Exit_Statement (Node8)
1359 -- Defined in E_Loop entity. The exit statements for a loop are chained
1360 -- (in reverse order of appearance) using this field to point to the
1361 -- first entry in the chain (last exit statement in the loop). The
1362 -- entries are chained through the Next_Exit_Statement field of the
1363 -- N_Exit_Statement node with Empty marking the end of the list.
1365 -- First_Formal (synthesized)
1366 -- Applies to subprograms and subprogram types, and also to entries
1367 -- and entry families. Returns first formal of the subprogram or entry.
1368 -- The formals are the first entities declared in a subprogram or in
1369 -- a subprogram type (the designated type of an Access_To_Subprogram
1370 -- definition) or in an entry.
1372 -- First_Formal_With_Extras (synthesized)
1373 -- Applies to subprograms and subprogram types, and also in entries
1374 -- and entry families. Returns first formal of the subprogram or entry.
1375 -- Returns Empty if there are no formals. The list returned includes
1376 -- all the extra formals (see description of Extra_Formals field).
1378 -- First_Index (Node17)
1379 -- Defined in array types and subtypes. By introducing implicit subtypes
1380 -- for the index constraints, we have the same structure for constrained
1381 -- and unconstrained arrays, subtype marks and discrete ranges are
1382 -- both represented by a subtype. This function returns the tree node
1383 -- corresponding to an occurrence of the first index (NOT the entity for
1384 -- the type). Subsequent indices are obtained using Next_Index. Note that
1385 -- this field is defined for the case of string literal subtypes, but is
1388 -- First_Literal (Node17)
1389 -- Defined in all enumeration types, including character and boolean
1390 -- types. This field points to the first enumeration literal entity
1391 -- for the type (i.e. it is set to First (Literals (N)) where N is
1392 -- the enumeration type definition node. A special case occurs with
1393 -- standard character and wide character types, where this field is
1394 -- Empty, since there are no enumeration literal lists in these cases.
1395 -- Note that this field is set in enumeration subtypes, but it still
1396 -- points to the first literal of the base type in this case.
1398 -- First_Private_Entity (Node16)
1399 -- Defined in all entities containing private parts (packages, protected
1400 -- types and subtypes, task types and subtypes). The entities on the
1401 -- entity chain are in order of declaration, so the entries for private
1402 -- entities are at the end of the chain. This field points to the first
1403 -- entity for the private part. It is Empty if there are no entities
1404 -- declared in the private part or if there is no private part.
1406 -- First_Rep_Item (Node6)
1407 -- Defined in all entities. If non-empty, points to a linked list of
1408 -- representation pragmas nodes and representation clause nodes that
1409 -- apply to the entity, linked using Next_Rep_Item, with Empty marking
1410 -- the end of the list. In the case of derived types and subtypes, the
1411 -- new entity inherits the chain at the point of declaration. This means
1412 -- that it is possible to have multiple instances of the same kind of rep
1413 -- item on the chain, in which case it is the first one that applies to
1416 -- Note: pragmas that can apply to more than one overloadable entity,
1417 -- (Convention, Interface, Inline, Inline_Always, Import, Export,
1418 -- External) are never present on this chain when they apply to
1419 -- overloadable entities, since it is impossible for a given pragma
1420 -- to be on more than one chain at a time.
1422 -- For most representation items, the representation information is
1423 -- reflected in other fields and flags in the entity. For example if a
1424 -- record representation clause is present, the component entities
1425 -- reflect the specified information. However, there are some items that
1426 -- are only reflected in the chain. These include:
1428 -- Machine_Attribute pragma
1429 -- Link_Alias pragma
1430 -- Linker_Constructor pragma
1431 -- Linker_Destructor pragma
1432 -- Weak_External pragma
1433 -- Thread_Local_Storage pragma
1435 -- If any of these items are present, then the flag Has_Gigi_Rep_Item is
1436 -- set, indicating that the backend should search the chain.
1438 -- Other representation items are included in the chain so that error
1439 -- messages can easily locate the relevant nodes for posting errors.
1440 -- Note in particular that size clauses are defined only for this
1441 -- purpose, and should only be accessed if Has_Size_Clause is set.
1443 -- Float_Rep (Uint10)
1444 -- Defined in floating-point entities. Contains a value of type
1445 -- Float_Rep_Kind. Together with the Digits_Value uniquely defines
1446 -- the floating-point representation to be used.
1448 -- Freeze_Node (Node7)
1449 -- Defined in all entities. If there is an associated freeze node for the
1450 -- entity, this field references this freeze node. If no freeze node is
1451 -- associated with the entity, then this field is Empty. See package
1452 -- Freeze for further details.
1454 -- From_Limited_With (Flag159)
1455 -- Defined in abtract states, package and type entities. Set to True when
1456 -- the related entity is generated by the expansion of a limited with
1457 -- clause. Such an entity is said to be a "shadow" - it acts as the
1458 -- abstract view of a state or variable or as the incomplete view of a
1459 -- type by inheriting relevant attributes from the said entity.
1461 -- Full_View (Node11)
1462 -- Defined in all type and subtype entities and in deferred constants.
1463 -- References the entity for the corresponding full type or constant
1464 -- declaration. For all types other than private and incomplete types,
1465 -- this field always contains Empty. If an incomplete type E1 is
1466 -- completed by a private type E2 whose full type declaration entity is
1467 -- E3 then the full view of E1 is E2, and the full view of E2 is E3. See
1468 -- also Underlying_Type.
1470 -- Generic_Homonym (Node11)
1471 -- Defined in generic packages. The generic homonym is the entity of
1472 -- a renaming declaration inserted in every generic unit. It is used
1473 -- to resolve the name of a local entity that is given by a qualified
1474 -- name, when the generic entity itself is hidden by a local name.
1476 -- Generic_Renamings (Elist23)
1477 -- Defined in package and subprogram instances. Holds mapping that
1478 -- associates generic parameters with the corresponding instances, in
1479 -- those cases where the instance is an entity.
1481 -- Handler_Records (List10)
1482 -- Defined in subprogram and package entities. Points to a list of
1483 -- identifiers referencing the handler record entities for the
1484 -- corresponding unit.
1486 -- Has_Aliased_Components (Flag135) [implementation base type only]
1487 -- Defined in array type entities. Indicates that the component type
1488 -- of the array is aliased. Should this also be set for records to
1489 -- indicate that at least one component is aliased (see processing in
1490 -- Sem_Prag.Process_Atomic_Independent_Shared_Volatile???)
1492 -- Has_Alignment_Clause (Flag46)
1493 -- Defined in all type entities and objects. Indicates if an alignment
1494 -- clause has been given for the entity. If set, then Alignment_Clause
1495 -- returns the N_Attribute_Definition node for the alignment attribute
1496 -- definition clause. Note that it is possible for this flag to be False
1497 -- even when Alignment_Clause returns non_Empty (this happens in the case
1498 -- of derived type declarations).
1500 -- Has_All_Calls_Remote (Flag79)
1501 -- Defined in all library unit entities. Set if the library unit has an
1502 -- All_Calls_Remote pragma. Note that such entities must also be RCI
1503 -- entities, so the flag Is_Remote_Call_Interface will always be set if
1504 -- this flag is set.
1506 -- Has_Atomic_Components (Flag86) [implementation base type only]
1507 -- Defined in all types and objects. Set only for an array type or
1508 -- an array object if a valid pragma Atomic_Components applies to the
1509 -- type or object. Note that in the case of an object, this flag is
1510 -- only set on the object if there was an explicit pragma for the
1511 -- object. In other words, the proper test for whether an object has
1512 -- atomic components is to see if either the object or its base type
1513 -- has this flag set. Note that in the case of a type, the pragma will
1514 -- be chained to the rep item chain of the first subtype in the usual
1517 -- Has_Attach_Handler (synthesized)
1518 -- Applies to record types that are constructed by the expander to
1519 -- represent protected types. Returns True if there is at least one
1520 -- Attach_Handler pragma in the corresponding specification.
1522 -- Has_Biased_Representation (Flag139)
1523 -- Defined in discrete types (where it applies to the type'size value),
1524 -- and to objects (both stand-alone and components), where it applies to
1525 -- the size of the object from a size or record component clause. In
1526 -- all cases it indicates that the size in question is smaller than
1527 -- would normally be required, but that the size requirement can be
1528 -- satisfied by using a biased representation, in which stored values
1529 -- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
1530 -- reduce the required size. For example, a type with a range of 1..2
1531 -- takes one bit, using 0 to represent 1 and 1 to represent 2.
1533 -- Note that in the object and component cases, the flag is only set if
1534 -- the type is unbiased, but the object specifies a smaller size than the
1535 -- size of the type, forcing biased representation for the object, but
1536 -- the subtype is still an unbiased type.
1538 -- Has_Completion (Flag26)
1539 -- Defined in all entities that require a completion (functions,
1540 -- procedures, private types, limited private types, incomplete types,
1541 -- constants and packages that require a body). The flag is set if the
1542 -- completion has been encountered and analyzed.
1544 -- Has_Completion_In_Body (Flag71)
1545 -- Defined in all entities for types and subtypes. Set only in "Taft
1546 -- amendment types" (incomplete types whose full declaration appears in
1547 -- the package body).
1549 -- Has_Complex_Representation (Flag140) [implementation base type only]
1550 -- Defined in record types. Set only for a base type to which a valid
1551 -- pragma Complex_Representation applies.
1553 -- Has_Component_Size_Clause (Flag68) [implementation base type only]
1554 -- Defined in all type entities. Set if a component size clause is
1555 -- Defined for the given type. Note that this flag can be False even
1556 -- if Component_Size is non-zero (happens in the case of derived types).
1558 -- Has_Constrained_Partial_View (Flag187)
1559 -- Defined in private type and their completions, when the private
1560 -- type has no discriminants and the full view has discriminants with
1561 -- defaults. In Ada 2005 heap-allocated objects of such types are not
1562 -- constrained, and can change their discriminants with full assignment.
1564 -- Ada 2012 has an additional rule (3.3. (23/10.3)) concerning objects
1565 -- declared in a generic package body. Objects whose type is an untagged
1566 -- generic formal private type are considered to have a constrained
1567 -- partial view. The predicate Object_Type_Has_Constrained_Partial_View
1568 -- in sem_aux is used to test for this case.
1570 -- Has_Contiguous_Rep (Flag181)
1571 -- Defined in enumeration types. Set if the type as a representation
1572 -- clause whose entries are successive integers.
1574 -- Has_Controlled_Component (Flag43) [base type only]
1575 -- Defined in all type and subtype entities. Set only for composite type
1576 -- entities which contain a component that either is a controlled type,
1577 -- or itself contains controlled component (i.e. either Is_Controlled or
1578 -- Has_Controlled_Component is set for at least one component).
1580 -- Has_Controlling_Result (Flag98)
1581 -- Defined in E_Function entities. Set if the function is a primitive
1582 -- function of a tagged type which can dispatch on result.
1584 -- Has_Convention_Pragma (Flag119)
1585 -- Defined in all entities. Set for an entity for which a valid pragma
1586 -- Convention, Import, or Export has been given. Used to prevent more
1587 -- than one such pragma appearing for a given entity (RM B.1(45)).
1589 -- Has_Default_Aspect (Flag39) [base type only]
1590 -- Defined in entities for types and subtypes, set for scalar types with
1591 -- a Default_Value aspect and array types with a Default_Component_Value
1592 -- aspect. If this flag is set, then a corresponding aspect specification
1593 -- node will be present on the rep item chain for the entity. For a
1594 -- derived type that inherits a default from its ancestor, the default
1595 -- value is set, but it may be overridden by an aspect declaration on
1598 -- Has_Delayed_Aspects (Flag200)
1599 -- Defined in all entities. Set if the Rep_Item chain for the entity has
1600 -- one or more N_Aspect_Definition nodes chained which are not to be
1601 -- evaluated till the freeze point. The aspect definition expression
1602 -- clause has been preanalyzed to get visibility at the point of use,
1603 -- but no other action has been taken.
1605 -- Has_Delayed_Freeze (Flag18)
1606 -- Defined in all entities. Set to indicate that an explicit freeze
1607 -- node must be generated for the entity at its freezing point. See
1608 -- separate section ("Delayed Freezing and Elaboration") for details.
1610 -- Has_Delayed_Rep_Aspects (Flag261)
1611 -- Defined in all types and subtypes. This flag is set if there is at
1612 -- least one aspect for a representation characteristic that has to be
1613 -- delayed and is one of the characteristics that may be inherited by
1614 -- types derived from this type if not overridden. If this flag is set,
1615 -- then types derived from this type have May_Inherit_Delayed_Rep_Aspects
1616 -- set, signalling that Freeze.Inherit_Delayed_Rep_Aspects must be called
1617 -- at the freeze point of the derived type.
1619 -- Has_DIC (syntherized)
1620 -- Defined in all type entities. Set for a private type and its full view
1621 -- when the type is subject to pragma Default_Initial_Condition (DIC), or
1622 -- when the type inherits a DIC pragma from a parent type.
1624 -- Has_Discriminants (Flag5)
1625 -- Defined in all types and subtypes. For types that are allowed to have
1626 -- discriminants (record types and subtypes, task types and subtypes,
1627 -- protected types and subtypes, private types, limited private types,
1628 -- and incomplete types), indicates if the corresponding type or subtype
1629 -- has a known discriminant part. Always false for all other types.
1631 -- Has_Dispatch_Table (Flag220)
1632 -- Defined in E_Record_Types that are tagged. Set to indicate that the
1633 -- corresponding dispatch table is already built. This flag is used to
1634 -- avoid duplicate construction of library level dispatch tables (because
1635 -- the declaration of library level objects cause premature construction
1636 -- of the table); otherwise the code that builds the table is added at
1637 -- the end of the list of declarations of the package.
1639 -- Has_Dynamic_Predicate_Aspect (Flag258)
1640 -- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect
1641 -- was explicitly applied to the type. Generally we treat predicates as
1642 -- static if possible, regardless of whether they are specified using
1643 -- Predicate, Static_Predicate, or Dynamic_Predicate. And if a predicate
1644 -- can be treated as static (i.e. its expression is predicate-static),
1645 -- then the flag Has_Static_Predicate will be set True. But there are
1646 -- cases where legality is affected by the presence of an explicit
1647 -- Dynamic_Predicate aspect. For example, even if a predicate looks
1648 -- static, you can't use it in a case statement if there is an explicit
1649 -- Dynamic_Predicate aspect specified. So test Has_Static_Predicate if
1650 -- you just want to know if the predicate can be evaluated statically,
1651 -- but test Has_Dynamic_Predicate_Aspect to enforce legality rules about
1652 -- the use of dynamic predicates.
1654 -- Has_Entries (synthesized)
1655 -- Applies to concurrent types. True if any entries are declared
1656 -- within the task or protected definition for the type.
1658 -- Has_Enumeration_Rep_Clause (Flag66)
1659 -- Defined in enumeration types. Set if an enumeration representation
1660 -- clause has been given for this enumeration type. Used to prevent more
1661 -- than one enumeration representation clause for a given type. Note
1662 -- that this does not imply a representation with holes, since the rep
1663 -- clause may merely confirm the default 0..N representation.
1665 -- Has_Exit (Flag47)
1666 -- Defined in loop entities. Set if the loop contains an exit statement.
1668 -- Has_Expanded_Contract (Flag240)
1669 -- Defined in functions, procedures, entries, and entry families. Set
1670 -- when a subprogram has a N_Contract node that has been expanded. The
1671 -- flag prevents double expansion of a contract when a construct is
1672 -- rewritten into something else and subsequently reanalyzed/expanded.
1674 -- Has_Foreign_Convention (synthesized)
1675 -- Applies to all entities. Determines if the Convention for the
1676 -- entity is a foreign convention (i.e. is other than Convention_Ada,
1677 -- Convention_Intrinsic, Convention_Entry or Convention_Protected).
1679 -- Has_Forward_Instantiation (Flag175)
1680 -- Defined in package entities. Set for packages that instantiate local
1681 -- generic entities before the corresponding generic body has been seen.
1682 -- If a package has a forward instantiation, we cannot inline subprograms
1683 -- appearing in the same package because the placement requirements of
1684 -- the instance will conflict with the linear elaboration of front-end
1687 -- Has_Fully_Qualified_Name (Flag173)
1688 -- Defined in all entities. Set if the name in the Chars field has been
1689 -- replaced by the fully qualified name, as used for debug output. See
1690 -- Exp_Dbug for a full description of the use of this flag and also the
1691 -- related flag Has_Qualified_Name.
1693 -- Has_Gigi_Rep_Item (Flag82)
1694 -- Defined in all entities. Set if the rep item chain (referenced by
1695 -- First_Rep_Item and linked through the Next_Rep_Item chain) contains a
1696 -- representation item that needs to be specially processed by the back
1697 -- end, i.e. one of the following items:
1699 -- Machine_Attribute pragma
1700 -- Linker_Alias pragma
1701 -- Linker_Constructor pragma
1702 -- Linker_Destructor pragma
1703 -- Weak_External pragma
1704 -- Thread_Local_Storage pragma
1706 -- If this flag is set, then the backend should scan the rep item chain
1707 -- to process any of these items that appear. At least one such item will
1710 -- Has_Homonym (Flag56)
1711 -- Defined in all entities. Set if an entity has a homonym in the same
1712 -- scope. Used by the backend to generate unique names for all entities.
1714 -- Has_Implicit_Dereference (Flag251)
1715 -- Defined in types and discriminants. Set if the type has an aspect
1716 -- Implicit_Dereference. Set also on the discriminant named in the aspect
1717 -- clause, to simplify type resolution.
1719 -- Has_Independent_Components (Flag34) [implementation base type only]
1720 -- Defined in all types and objects. Set only for a record type or an
1721 -- array type or array object if a valid pragma Independent_Components
1722 -- applies to the type or object. Note that in the case of an object,
1723 -- this flag is only set on the object if there was an explicit pragma
1724 -- for the object. In other words, the proper test for whether an object
1725 -- has independent components is to see if either the object or its base
1726 -- type has this flag set. Note that in the case of a type, the pragma
1727 -- will be chained to the rep item chain of the first subtype in the
1730 -- Has_Inheritable_Invariants (Flag248) [base type only]
1731 -- Defined in all type entities. Set on private types and interface types
1732 -- which define at least one class-wide invariant. Such invariants must
1733 -- be inherited by derived types. The flag is also set on the full view
1734 -- of a private type for completeness.
1736 -- Has_Inherited_DIC (Flag133) [base type only]
1737 -- Defined in all type entities. Set for a derived type which inherits
1738 -- pragma Default_Initial_Condition from a parent type.
1740 -- Has_Inherited_Invariants (Flag291) [base type only]
1741 -- Defined in all type entities. Set on private extensions and derived

1744 -- extension for completeness.
1746 -- Has_Initial_Value (Flag219)
1747 -- Defined in entities for variables and out parameters. Set if there
1748 -- is an explicit initial value expression in the declaration of the
1749 -- variable. Note that this is set only if this initial value is
1750 -- explicit, it is not set for the case of implicit initialization
1751 -- of access types or controlled types. Always set to False for out
1752 -- parameters. Also defined in entities for in and in-out parameters,
1753 -- but always false in these cases.
1755 -- Has_Interrupt_Handler (synthesized)
1756 -- Applies to all protected type entities. Set if the protected type
1757 -- definition contains at least one procedure to which a pragma
1758 -- Interrupt_Handler applies.
1760 -- Has_Invariants (synthesized)
1761 -- Defined in all type entities. True if the type defines at least one
1762 -- invariant of its own or inherits at least one class-wide invariant
1763 -- from a parent type or an interface.
1765 -- Has_Loop_Entry_Attributes (Flag260)
1766 -- Defined in E_Loop entities. Set when the loop is subject to at least
1767 -- one attribute 'Loop_Entry. The flag also implies that the loop has
1768 -- already been transformed. See Expand_Loop_Entry_Attribute for details.
1770 -- Has_Machine_Radix_Clause (Flag83)
1771 -- Defined in decimal types and subtypes, set if a Machine_Radix
1772 -- representation clause is present. This flag is used to detect

1776 -- Defined in entities that can appear in the scope stack (see spec
1777 -- of Sem). It is set if a task master entity (_master) has been
1778 -- declared and initialized in the corresponding scope.
1780 -- Has_Missing_Return (Flag142)
1781 -- Defined in functions and generic functions. Set if there is one or
1782 -- more missing return statements in the function. This is used to
1783 -- control wrapping of the body in Exp_Ch6 to ensure that the program
1784 -- error exception is correctly raised in this case at run time.
1786 -- Has_Nested_Block_With_Handler (Flag101)
1787 -- Defined in scope entities. Set if there is a nested block within the
1788 -- scope that has an exception handler and the two scopes are in the

1790 -- optimizations to ensure that they are consistent with exceptions.
1791 -- See documentation in backend for further details.
1793 -- Has_Nested_Subprogram (Flag282)
1794 -- Defined in subprogram entities. Set for a subprogram which contains at

1809 -- in aspect/pragma Refined_State.
1811 -- Has_Non_Standard_Rep (Flag75) [implementation base type only]
1812 -- Defined in all type entities. Set when some representation clause
1813 -- or pragma causes the representation of the item to be significantly
1814 -- modified. In this category are changes of small or radix for a
1815 -- fixed-point type, change of component size for an array, and record
1816 -- or enumeration representation clauses, as well as packed pragmas.
1817 -- All other representation clauses (e.g. Size and Alignment clauses)
1818 -- are not considered to be significant since they do not affect
1819 -- stored bit patterns.
1821 -- Has_Null_Abstract_State (synth)
1822 -- Defined in package entities. True if the package is subject to a null
1823 -- Abstract_State aspect/pragma.

1829 -- Has_Object_Size_Clause (Flag172)
1830 -- Defined in entities for types and subtypes. Set if an Object_Size

1841 -- when the type is subject to pragma Default_Initial_Condition.
1843 -- Has_Own_Invariants (Flag232) [base type only]
1844 -- Defined in all type entities. Set on any type which defines at least
1845 -- one invariant of its own. The flag is also set on the full view of a
1846 -- private type for completeness.
1848 -- Has_Partial_Visible_Refinement (Flag296)
1849 -- Defined in E_Abstract_State entities. Set when a state has at least
1850 -- one refinement constituent subject to indicator Part_Of, and analysis
1851 -- is in the region between the declaration of the first constituent for
1852 -- this abstract state (in the private part of the package) and the end
1853 -- of the package spec or body with visibility over this private part
1854 -- (which includes the package itself and its child packages).
1856 -- Has_Per_Object_Constraint (Flag154)
1857 -- Defined in E_Component entities. Set if the subtype of the component
1858 -- has a per object constraint. Per object constraints result from the

1882 -- pragma Inline or Inline_Always applies to the subprogram. Note that
1883 -- this flag can be set even if Is_Inlined is not set. This happens for
1884 -- pragma Inline (if Inline_Active is False). In other words, the flag
1885 -- Has_Pragma_Inline represents the formal semantic status, and is used
1886 -- for checking semantic correctness. The flag Is_Inlined indicates
1887 -- whether inlining is actually active for the entity.
1889 -- Has_Pragma_Inline_Always (Flag230)
1890 -- Defined in all entities. Set for functions and procedures for which a
1891 -- pragma Inline_Always applies. Note that if this flag is set, the flag

1894 -- Has_Pragma_No_Inline (Flag201)
1895 -- Defined in all entities. Set for functions and procedures for which a
1896 -- pragma No_Inline applies. Note that if this flag is set, the flag
1897 -- Has_Pragma_Inline_Always cannot be set.
1899 -- Has_Pragma_Ordered (Flag198) [implementation base type only]
1900 -- Defined in entities for enumeration types. If set indicates that a
1901 -- valid pragma Ordered was given for the type. This flag is inherited
1902 -- by derived enumeration types. We don't need to distinguish the derived
1903 -- case since we allow multiple occurrences of this pragma anyway.
1905 -- Has_Pragma_Pack (Flag121) [implementation base type only]
1906 -- Defined in array and record type entities. If set, indicates that a
1907 -- valid pragma Pack was given for the type. Note that this flag is not

1919 -- Has_Pragma_Pure_Function (Flag179)
1920 -- Defined in all entities. If set, indicates that a valid pragma
1921 -- Pure_Function was given for the entity. In some cases, we need to test

1930 -- Has_Pragma_Unmodified (Flag233)
1931 -- Defined in all entities. Can only be set for variables (E_Variable,
1932 -- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified
1933 -- applies to the variable, indicating that no warning should be given
1934 -- if the entity is never modified. Note that clients should generally
1935 -- not test this flag directly, but instead use function Has_Unmodified.
1937 -- Has_Pragma_Unreferenced (Flag180)
1938 -- Defined in all entities. Set if a valid pragma Unreferenced applies
1939 -- to the entity, indicating that no warning should be given if the
1940 -- entity has no references, but a warning should be given if it is
1941 -- in fact referenced. For private types, this flag is set in both the
1942 -- private entity and full entity if the pragma applies to either. Note
1943 -- that clients should generally not test this flag directly, but instead
1944 -- use function Has_Unreferenced.
1946 -- ??? this real description was clobbered
1948 -- Has_Pragma_Unreferenced_Objects (Flag212)
1949 -- Defined in all entities. Set if a valid pragma Unused applies to an

1951 -- modified or referenced. This pragma is equivalent to a pair of
1952 -- Unmodified and Unreferenced pragmas.
1954 -- Has_Pragma_Unused (Flag294)
1955 -- Defined in all entries. Set if a valid pragma Unused applies to a
1956 -- variable or entity, indicating that warnings should not be given if
1957 -- it is never modified or referenced. Note: This pragma is exactly
1958 -- equivalent Unmodified and Unreference combined.
1960 -- Has_Predicates (Flag250)
1961 -- Defined in type and subtype entities. Set if a pragma Predicate or
1962 -- Predicate aspect applies to the type or subtype, or if it inherits a

1966 -- a Predicate pragma or aspect applies.
1968 -- Has_Primitive_Operations (Flag120) [base type only]

1970 -- is defined for the type.
1972 -- Has_Private_Ancestor (Flag151)
1973 -- Applies to type extensions. True if some ancestor is derived from a
1974 -- private type, making some components invisible and aggregates illegal.
1975 -- This flag is set at the point of derivation. The legality of the
1976 -- aggregate must be rechecked because it also depends on the visibility
1977 -- at the point the aggregate is resolved. See sem_aggr.adb. This is part
1980 -- Has_Private_Declaration (Flag155)
1981 -- Defined in all entities. Set if it is the defining entity of a private
1982 -- type declaration or its corresponding full declaration. This flag is
1983 -- thus preserved when the full and the partial views are exchanged, to
1984 -- indicate if a full type declaration is a completion. Used for semantic
1985 -- checks in E.4(18) and elsewhere.
1987 -- Has_Private_Extension (Flag300)
1988 -- Defined in tagged types. Set to indicate that the tagged type has some
1989 -- private extension. Used to report a warning on public primitives added
1990 -- after defining its private extensions.
1992 -- Has_Protected (Flag271) [base type only]
1993 -- Defined in all type entities. Set on protected types themselves, and
1994 -- also (recursively) on any composite type which has a component for
1995 -- which Has_Protected is set, unless the protected type is declared in
1996 -- the private part of an internal unit. The meaning is that restrictions
1997 -- for protected types apply to this type. Note: the flag is not set on
1998 -- access types, even if they designate an object that Has_Protected.
2000 -- Has_Qualified_Name (Flag161)
2001 -- Defined in all entities. Set if the name in the Chars field has
2002 -- been replaced by its qualified name, as used for debug output. See
2003 -- Exp_Dbug for a full description of qualification requirements. For
2004 -- some entities, the name is the fully qualified name, but there are
2005 -- exceptions. In particular, for local variables in procedures, we
2006 -- do not include the procedure itself or higher scopes. See also the
2007 -- flag Has_Fully_Qualified_Name, which is set if the name does indeed
2008 -- include the fully qualified name.
2010 -- Has_RACW (Flag214)
2011 -- Defined in package spec entities. Set if the spec contains the
2012 -- declaration of a remote access-to-classwide type.
2014 -- Has_Record_Rep_Clause (Flag65) [implementation base type only]
2015 -- Defined in record types. Set if a record representation clause has
2016 -- been given for this record type. Used to prevent more than one such
2017 -- clause for a given record type. Note that this is initially cleared
2018 -- for a derived type, even though the representation is inherited. See
2019 -- also the flag Has_Specified_Layout.
2021 -- Has_Recursive_Call (Flag143)
2022 -- Defined in procedures. Set if a direct parameterless recursive call
2023 -- is detected while analyzing the body. Used to activate some error
2024 -- checks for infinite recursion.
2026 -- Has_Shift_Operator (Flag267) [base type only]
2027 -- Defined in integer types. Set in the base type of an integer type for
2028 -- which at least one of the shift operators is defined.
2030 -- Has_Size_Clause (Flag29)
2031 -- Defined in entities for types and objects. Set if a size clause is
2032 -- defined for the entity. Used to prevent multiple Size clauses for a
2033 -- given entity. Note that it is always initially cleared for a derived
2034 -- type, even though the Size for such a type is inherited from a Size
2035 -- clause given for the parent type.
2037 -- Has_Small_Clause (Flag67)
2038 -- Defined in ordinary fixed point types (but not subtypes). Indicates
2039 -- that a small clause has been given for the entity. Used to prevent
2040 -- multiple Small clauses for a given entity. Note that it is always
2041 -- initially cleared for a derived type, even though the Small for such
2042 -- a type is inherited from a Small clause given for the parent type.
2044 -- Has_Specified_Layout (Flag100) [implementation base type only]
2045 -- Defined in all type entities. Set for a record type or subtype if
2046 -- the record layout has been specified by a record representation
2047 -- clause. Note that this differs from the flag Has_Record_Rep_Clause
2048 -- in that it is inherited by a derived type. Has_Record_Rep_Clause is
2049 -- used to indicate that the type is mentioned explicitly in a record
2050 -- representation clause, and thus is not inherited by a derived type.
2051 -- This flag is always False for non-record types.
2053 -- Has_Specified_Stream_Input (Flag190)
2054 -- Has_Specified_Stream_Output (Flag191)
2055 -- Has_Specified_Stream_Read (Flag192)
2056 -- Has_Specified_Stream_Write (Flag193)
2057 -- Defined in all type and subtype entities. Set for a given view if the
2058 -- corresponding stream-oriented attribute has been defined by an
2059 -- attribute definition clause. When such a clause occurs, a TSS is set
2060 -- on the underlying full view; the flags are used to track visibility of
2061 -- the attribute definition clause for partial or incomplete views.
2063 -- Has_Static_Discriminants (Flag211)
2064 -- Defined in record subtypes constrained by discriminant values. Set if
2065 -- all the discriminant values have static values, meaning that in the
2066 -- case of a variant record, the component list can be trimmed down to
2067 -- include only the components corresponding to these discriminants.
2069 -- Has_Static_Predicate (Flag269)
2070 -- Defined in all types and subtypes. Set if the type (which must be a
2071 -- scalar type) has a predicate whose expression is predicate-static.
2072 -- This can result from the use of any Predicate, Static_Predicate, or
2073 -- Dynamic_Predicate aspect. We can distinguish these cases by testing
2074 -- Has_Static_Predicate_Aspect and Has_Dynamic_Predicate_Aspect. See
2075 -- description of the latter flag for further information on dynamic
2076 -- predicates which are also static.
2078 -- Has_Static_Predicate_Aspect (Flag259)
2079 -- Defined in all types and subtypes. Set if a Static_Predicate aspect
2080 -- applies to the type. Note that we can tell if a static predicate is
2081 -- present by looking at Has_Static_Predicate, but this could have come
2082 -- from a Predicate aspect or pragma or even from a Dynamic_Predicate
2083 -- aspect. When we need to know the difference (e.g. to know what set of
2084 -- check policies apply, use this flag and Has_Dynamic_Predicate_Aspect
2085 -- to determine which case we have).
2087 -- Has_Storage_Size_Clause (Flag23) [implementation base type only]
2088 -- Defined in task types and access types. It is set if a Storage_Size
2089 -- clause is present for the type. Used to prevent multiple clauses for
2090 -- one type. Note that this flag is initially cleared for a derived type
2091 -- even though the Storage_Size for such a type is inherited from a
2092 -- Storage_Size clause given for the parent type. Note that in the case
2093 -- of access types, this flag is defined only in the root type, since a
2094 -- storage size clause cannot be given to a derived type.
2096 -- Has_Stream_Size_Clause (Flag184)
2097 -- Defined in all entities. It is set for types which have a Stream_Size
2098 -- clause attribute. Used to prevent multiple Stream_Size clauses for a
2099 -- given entity, and also whether it is necessary to check for a stream
2102 -- Has_Task (Flag30) [base type only]
2103 -- Defined in all type entities. Set on task types themselves, and also
2104 -- (recursively) on any composite type which has a component for which
2105 -- Has_Task is set. The meaning is that an allocator or declaration of
2106 -- such an object must create the required tasks. Note: the flag is not
2107 -- set on access types, even if they designate an object that Has_Task.
2109 -- Has_Timing_Event (Flag289) [base type only]
2110 -- Defined in all type entities. Set on language defined type
2111 -- Ada.Real_Time.Timing_Events.Timing_Event, and also (recursively) on
2112 -- any composite type which has a component for which Has_Timing_Event
2113 -- is set. Used for the No_Local_Timing_Event restriction.
2115 -- Has_Thunks (Flag228)
2116 -- Applies to E_Constant entities marked Is_Tag. True for secondary tag
2117 -- referencing a dispatch table whose contents are pointers to thunks.
2119 -- Has_Unchecked_Union (Flag123) [base type only]
2120 -- Defined in all type entities. Set on unchecked unions themselves
2121 -- and (recursively) on any composite type which has a component for
2122 -- which Has_Unchecked_Union is set. The meaning is that a comparison
2123 -- operation or 'Valid_Scalars reference for the type is not permitted.
2124 -- Note that the flag is not set on access types, even if they designate
2125 -- an object that has the flag Has_Unchecked_Union set.
2127 -- Has_Unknown_Discriminants (Flag72)
2128 -- Defined in all entities. Set for types with unknown discriminants.
2129 -- Types can have unknown discriminants either from their declaration or
2130 -- through type derivation. The use of this flag exactly meets the spec
2131 -- in RM 3.7(26). Note that all class-wide types are considered to have
2132 -- unknown discriminants. Note that both flags Has_Discriminants and
2133 -- Has_Unknown_Discriminants may be true for a type. Class-wide types and
2134 -- their subtypes have unknown discriminants and can have declared ones
2135 -- as well. Private types declared with unknown discriminants may have a
2136 -- full view that has explicit discriminants, and both flag will be set
2137 -- on the partial view, to ensure that discriminants are properly
2138 -- inherited in certain contexts.
2140 -- Has_Visible_Refinement (Flag263)
2141 -- Defined in E_Abstract_State entities. Set when a state has at least
2142 -- one refinement constituent and analysis is in the region between
2143 -- pragma Refined_State and the end of the package body declarations.
2145 -- Has_Volatile_Components (Flag87) [implementation base type only]
2146 -- Defined in all types and objects. Set only for an array type or array
2147 -- object if a valid pragma Volatile_Components or a valid pragma
2148 -- Atomic_Components applies to the type or object. Note that in the case
2149 -- of an object, this flag is only set on the object if there was an
2150 -- explicit pragma for the object. In other words, the proper test for
2151 -- whether an object has volatile components is to see if either the
2152 -- object or its base type has this flag set. Note that in the case of a
2153 -- type the pragma will be chained to the rep item chain of the first
2154 -- subtype in the usual manner.
2156 -- Has_Xref_Entry (Flag182)
2157 -- Defined in all entities. Set if an entity has an entry in the Xref
2158 -- information generated in ali files. This is true for all source
2159 -- entities in the extended main source file. It is also true of entities
2160 -- in other packages that are referenced directly or indirectly from the
2161 -- main source file (indirect reference occurs when the main source file
2162 -- references an entity with a type reference. See package Lib.Xref for
2163 -- further details).
2165 -- Hiding_Loop_Variable (Node8)
2166 -- Defined in variables. Set only if a variable of a discrete type is
2167 -- hidden by a loop variable in the same local scope, in which case
2168 -- the Hiding_Loop_Variable field of the hidden variable points to
2169 -- the E_Loop_Parameter entity doing the hiding. Used in processing
2170 -- warning messages if the hidden variable turns out to be unused
2171 -- or is referenced without being set.
2173 -- Hidden_In_Formal_Instance (Elist30)
2174 -- Defined on actuals for formal packages. Entities on the list are
2175 -- formals that are hidden outside of the formal package when this
2176 -- package is not declared with a box, or the formal itself is not
2177 -- defaulted (see RM 12.7 (10)). Their visibility is restored on exit
2178 -- from the current generic, because the actual for the formal package
2179 -- may be used subsequently in the current unit.
2182 -- Defined in all entities. Link for list of entities that have the
2183 -- same source name and that are declared in the same or enclosing
2184 -- scopes. Homonyms in the same scope are overloaded. Used for name
2185 -- resolution and for the generation of debugging information.
2187 -- Ignore_SPARK_Mode_Pragmas (Flag301)
2188 -- Present in concurrent type, entry, operator, [generic] package,
2189 -- package body, [generic] subprogram, and subprogram body entities.
2190 -- Set when the entity appears in an instance subject to SPARK_Mode
2191 -- "off" and indicates that all SPARK_Mode pragmas found within must
2194 -- Implementation_Base_Type (synthesized)
2195 -- Applies to all entities. For types, similar to Base_Type, but never
2196 -- returns a private type when applied to a non-private type. Instead in
2197 -- this case, it always returns the Underlying_Type of the base type, so
2198 -- that we still have a concrete type. For entities other than types,
2199 -- returns the entity unchanged.
2201 -- Import_Pragma (Node35)
2202 -- Defined in subprogram entities. Set if a valid pragma Import or pragma
2203 -- Import_Function or pragma Import_Procedure applies to the subprogram,
2204 -- in which case this field points to the pragma (we can't use the normal
2205 -- Rep_Item chain mechanism, because a single pragma Import can apply
2206 -- to multiple subprogram entities).
2208 -- In_Package_Body (Flag48)
2209 -- Defined in package entities. Set on the entity that denotes the
2210 -- package (the defining occurrence of the package declaration) while
2211 -- analyzing and expanding the package body. Reset on completion of
2212 -- analysis/expansion.
2214 -- In_Private_Part (Flag45)
2215 -- Defined in all entities. Can be set only in package entities and
2216 -- objects. For package entities, this flag is set to indicate that the
2217 -- private part of the package is being analyzed. The flag is reset at
2218 -- the end of the package declaration. For objects it indicates that the
2219 -- declaration of the object occurs in the private part of a package.
2221 -- Incomplete_Actuals (Elist24)
2222 -- Defined on package entities that are instances. Indicates the actuals
2223 -- types in the instantiation that are limited views. If this list is
2224 -- not empty, the instantiation, which appears in a package declaration,
2225 -- is relocated to the corresponding package body, which must have a
2226 -- corresponding nonlimited with_clause.
2228 -- Initialization_Statements (Node28)
2229 -- Defined in constants and variables. For a composite object initialized
2230 -- initialized with an aggregate that has been converted to a sequence
2231 -- of assignments, points to a block statement containing the
2234 -- Inner_Instances (Elist23)
2235 -- Defined in generic units. Contains element list of units that are
2236 -- instantiated within the given generic. Used to diagnose circular
2239 -- Interface_Alias (Node25)
2240 -- Defined in subprograms that cover a primitive operation of an abstract
2241 -- interface type. Can be set only if the Is_Hidden flag is also set,
2242 -- since such entities are always hidden. Points to its associated
2243 -- interface subprogram. It is used to register the subprogram in
2244 -- secondary dispatch table of the interface (Ada 2005: AI-251).
2246 -- Interface_Name (Node21)
2247 -- Defined in constants, variables, exceptions, functions, procedures,
2248 -- and packages. Set to Empty unless an export, import, or interface name
2249 -- pragma has explicitly specified an external name, in which case it
2250 -- references an N_String_Literal node for the specified external name.
2251 -- Note that if this field is Empty, and Is_Imported or Is_Exported is
2252 -- set, then the default interface name is the name of the entity, cased
2253 -- in a manner that is appropriate to the system in use. Note that
2254 -- Interface_Name is ignored if an address clause is present (since it
2255 -- is meaningless in this case).
2257 -- Interfaces (Elist25)
2258 -- Defined in record types and subtypes. List of abstract interfaces
2259 -- implemented by a tagged type that are not already implemented by the
2260 -- ancestors (Ada 2005: AI-251).
2262 -- Invariant_Procedure (synthesized)
2263 -- Defined in types and subtypes. Set for private types and their full
2264 -- views if one or more [class-wide] invariants apply to the type, or
2265 -- when the type inherits class-wide invariants from a parent type or
2266 -- an interface, or when the type is an array and its component type is
2267 -- subject to an invariant, or when the type is record and contains a
2268 -- component subject to an invariant (property is recursive). Points to
2269 -- to the entity for a procedure which checks all these invariants. The
2270 -- invariant procedure takes a single argument of the given type, and
2271 -- returns if the invariant holds, or raises exception Assertion_Error
2272 -- with an appropriate message if it does not hold. This attribute is
2273 -- defined but always Empty for private subtypes.
2275 -- Note: the reason this is marked as a synthesized attribute is that the
2276 -- way this is stored is as an element of the Subprograms_For_Type field.
2279 -- Defined in packages and types. Set when analyzing a use clause for
2280 -- the corresponding entity. Reset at end of corresponding declarative
2281 -- part. The flag on a type is also used to determine the visibility of
2282 -- the primitive operators of the type.
2284 -- Is_Abstract_Subprogram (Flag19)
2285 -- Defined in all subprograms and entries. Set for abstract subprograms.
2286 -- Always False for enumeration literals and entries. See also
2287 -- Requires_Overriding.

2290 -- Defined in all types. Set for abstract types.
2292 -- Is_Access_Constant (Flag69)
2293 -- Defined in access types and subtypes. Indicates that the keyword
2294 -- constant was present in the access type definition.
2296 -- Is_Access_Protected_Subprogram_Type (synthesized)
2297 -- Applies to all types, true for named and anonymous access to
2298 -- protected subprograms.
2300 -- Is_Access_Type (synthesized)
2301 -- Applies to all entities, true for access types and subtypes
2303 -- Is_Activation_Record (Flag305)
2304 -- Applies to E_In_Parameters generated in Exp_Unst for nested
2305 -- subprograms, to mark the added formal that carries the activation
2306 -- record created in the enclosing subprogram.
2308 -- Is_Actual_Subtype (Flag293)
2309 -- Defined on all types, true for the generated constrained subtypes
2310 -- that are built for unconstrained composite actuals.
2312 -- Is_Ada_2005_Only (Flag185)
2313 -- Defined in all entities, true if a valid pragma Ada_05 or Ada_2005
2314 -- applies to the entity which specifically names the entity, indicating
2315 -- that the entity is Ada 2005 only. Note that this flag is not set if
2316 -- the entity is part of a unit compiled with the normal no-argument form
2317 -- of pragma Ada_05 or Ada_2005.
2319 -- Is_Ada_2012_Only (Flag199)
2320 -- Defined in all entities, true if a valid pragma Ada_12 or Ada_2012
2321 -- applies to the entity which specifically names the entity, indicating
2322 -- that the entity is Ada 2012 only. Note that this flag is not set if
2323 -- the entity is part of a unit compiled with the normal no-argument form
2324 -- of pragma Ada_12 or Ada_2012.
2326 -- Is_Aliased (Flag15)
2327 -- Defined in all entities. Set for objects and types whose declarations
2328 -- carry the keyword aliased, and on record components that have the
2329 -- keyword. For Ada 2012, also applies to formal parameters.
2331 -- Is_Array_Type (synthesized)
2332 -- Applies to all entities, true for array types and subtypes
2334 -- Is_Asynchronous (Flag81)
2335 -- Defined in all type entities and in procedure entities. Set
2336 -- if a pragma Asynchronous applies to the entity.
2338 -- Is_Atomic (Flag85)
2339 -- Defined in all type entities, and also in constants, components, and
2340 -- variables. Set if a pragma Atomic or Shared applies to the entity.
2341 -- In the case of private and incomplete types, this flag is set in
2342 -- both the partial view and the full view.
2344 -- Is_Atomic_Or_VFA (synth)
2345 -- Defined in all type entities, and also in constants, components and
2346 -- variables. Set if a pragma Atomic or Shared or Volatile_Full_Access
2347 -- applies to the entity. For many purposes VFA objects should be treated
2348 -- the same as Atomic objects, and this predicate is intended for that
2349 -- usage. In the case of private and incomplete types, the predicate
2350 -- applies to both the partial view and the full view.
2352 -- Is_Base_Type (synthesized)
2353 -- Applies to type and subtype entities. True if entity is a base type.
2355 -- Is_Bit_Packed_Array (Flag122) [implementation base type only]
2356 -- Defined in all entities. This flag is set for a packed array type that
2357 -- is bit-packed (i.e. the component size is known by the front end and
2358 -- is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed is always set
2359 -- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be
2360 -- set without Is_Bit_Packed_Array if the component size is not known by
2361 -- the front-end or for the case of an array having one or more index
2362 -- types that are enumeration types with non-standard representation.
2364 -- Is_Boolean_Type (synthesized)
2365 -- Applies to all entities, true for boolean types and subtypes,
2366 -- i.e. Standard.Boolean and all types ultimately derived from it.

2379 -- [generic] subprograms, components, discriminants, formal parameters,
2380 -- objects, package bodies, subprogram bodies, and [sub]types subject to

2384 -- Is_Child_Unit (Flag73)
2385 -- Defined in all entities. Set only for defining entities of program
2386 -- units that are child units (but False for subunits).
2388 -- Is_Class_Wide_Clone (Flag290)
2389 -- Defined on subprogram entities. Set for subprograms built in order
2390 -- to implement properly the inheritance of class-wide pre- or post-
2391 -- conditions when the condition contains calls to other primitives
2392 -- of the ancestor type. Used to implement AI12-0195.
2394 -- Is_Class_Wide_Equivalent_Type (Flag35)
2395 -- Defined in record types and subtypes. Set to True, if the type acts
2396 -- as a class-wide equivalent type, i.e. the Equivalent_Type field of
2397 -- some class-wide subtype entity references this record type.
2399 -- Is_Class_Wide_Type (synthesized)
2400 -- Applies to all entities, true for class wide types and subtypes
2402 -- Is_Compilation_Unit (Flag149)
2403 -- Defined in all entities. Set if the entity is a package or subprogram
2404 -- entity for a compilation unit other than a subunit (since we treat
2405 -- subunits as part of the same compilation operation as the ultimate
2406 -- parent, we do not consider them to be separate units for this flag).
2408 -- Is_Completely_Hidden (Flag103)
2409 -- Defined on discriminants. Only set on girder discriminants of
2410 -- untagged types. When set, the entity is a girder discriminant of a
2411 -- derived untagged type which is not directly visible in the derived
2412 -- type because the derived type or one of its ancestors have renamed the
2413 -- discriminants in the root type. Note: there are girder discriminants
2414 -- which are not Completely_Hidden (e.g. discriminants of a root type).
2416 -- Is_Composite_Type (synthesized)
2417 -- Applies to all entities, true for all composite types and subtypes.
2418 -- Either Is_Composite_Type or Is_Elementary_Type (but not both) is true
2421 -- Is_Concurrent_Record_Type (Flag20)
2422 -- Defined in record types and subtypes. Set if the type was created
2423 -- by the expander to represent a task or protected type. For every
2424 -- concurrent type, such as record type is constructed, and task and
2425 -- protected objects are instances of this record type at run time
2426 -- (The backend will replace declarations of the concurrent type using
2427 -- the declarations of the corresponding record type). See Exp_Ch9 for
2430 -- Is_Concurrent_Type (synthesized)
2431 -- Applies to all entities, true for task types and subtypes and for
2432 -- protected types and subtypes.
2434 -- Is_Constant_Object (synthesized)

2436 -- E_In_Parameter entities.
2438 -- Is_Constrained (Flag12)
2439 -- Defined in types or subtypes which may have index, discriminant
2440 -- or range constraint (i.e. array types and subtypes, record types

2442 -- Set if the type or subtype is constrained.
2444 -- Is_Constr_Subt_For_U_Nominal (Flag80)
2445 -- Defined in all types and subtypes. Set only for the constructed
2446 -- subtype of an object whose nominal subtype is unconstrained. Note
2447 -- that the constructed subtype itself will be constrained.
2449 -- Is_Constr_Subt_For_UN_Aliased (Flag141)
2450 -- Defined in all types and subtypes. This flag can be set only if
2451 -- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in

2453 -- the backend to determine whether a template must be constructed.
2455 -- Is_Constructor (Flag76)
2456 -- Defined in function and procedure entities. Set if a pragma
2457 -- CPP_Constructor applies to the subprogram.
2459 -- Is_Controlled_Active (Flag42) [base type only]

2461 -- i.e. is either a descendant of Ada.Finalization.Controlled or of
2462 -- Ada.Finalization.Limited_Controlled.
2464 -- Is_Controlled (synth) [base type only]
2465 -- Defined in all type entities. Set if Is_Controlled_Active is set for
2466 -- the type, and Disable_Controlled is not set.
2468 -- Is_Controlling_Formal (Flag97)
2469 -- Defined in all Formal_Kind entities. Marks the controlling parameters
2470 -- of dispatching operations.
2472 -- Is_CPP_Class (Flag74)
2473 -- Defined in all type entities, set only for tagged types to which a
2474 -- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied.

2477 -- Applies to all type entities, true for decimal fixed point
2478 -- types and subtypes.
2480 -- Is_Descendant_Of_Address (Flag223)

2513 -- Defined in all entities. Set for procedures, functions, generic
2514 -- procedures, and generic functions if the corresponding operation

2519 -- scope (i.e. a block, subprogram, task_type, entry or extended return
2522 -- Is_Elaboration_Checks_OK_Id (Flag148)
2523 -- Defined in elaboration targets (see terminology in Sem_Elab). Set when
2524 -- the target appears in a region which is subject to elabled elaboration
2525 -- checks. Such targets are allowed to generate run-time conditional ABE
2526 -- checks or guaranteed ABE failures.
2528 -- Is_Elaboration_Target (synthesized)

2537 -- Applies to all entities, True for all elementary types and subtypes.
2538 -- Either Is_Composite_Type or Is_Elementary_Type (but not both) is true
2541 -- Is_Eliminated (Flag124)
2542 -- Defined in type entities, subprogram entities, and object entities.
2543 -- Indicates that the corresponding entity has been eliminated by use
2544 -- of pragma Eliminate. Also used to mark subprogram entities whose
2545 -- declaration and body are within unreachable code that is removed.
2547 -- Is_Entry (synthesized)
2548 -- Applies to all entities, True only for entry and entry family
2549 -- entities and False for all other entity kinds.
2551 -- Is_Entry_Formal (Flag52)
2552 -- Defined in all entities. Set only for entry formals (which can only
2553 -- be in, in-out or out parameters). This flag is used to speed up the
2554 -- test for the need to replace references in Exp_Ch2.
2556 -- Is_Entry_Wrapper (Flag297)
2557 -- Defined on wrappers created for entries that have precondition aspects
2559 -- Is_Enumeration_Type (synthesized)
2560 -- Defined in all entities, true for enumeration types and subtypes
2562 -- Is_Exception_Handler (Flag286)
2563 -- Defined in blocks. Set if the block serves only as a scope of an
2564 -- exception handler with a choice parameter. Such a block does not
2565 -- physically appear in the tree.
2567 -- Is_Exported (Flag99)
2568 -- Defined in all entities. Set if the entity is exported. For now we
2569 -- only allow the export of constants, exceptions, functions, procedures
2570 -- and variables, but that may well change later on. Exceptions can only
2571 -- be exported in the Java VM implementation of GNAT, which is retired.
2573 -- Is_External_State (synthesized)
2574 -- Applies to all entities, true for abstract states that are subject to
2575 -- option External or Synchronous.
2577 -- Is_Finalized_Transient (Flag252)
2578 -- Defined in constants, loop parameters of generalized iterators, and
2579 -- variables. Set when a transient object has been finalized by one of
2580 -- the transient finalization mechanisms. The flag prevents the double
2581 -- finalization of the object.
2583 -- Is_Finalizer (synthesized)
2584 -- Applies to all entities, true for procedures containing finalization
2585 -- code to process local or library level objects.
2587 -- Is_First_Subtype (Flag70)
2588 -- Defined in all entities. True for first subtypes (RM 3.2.1(6)),
2589 -- i.e. the entity in the type declaration that introduced the type.
2590 -- This may be the base type itself (e.g. for record declarations and
2591 -- enumeration type declarations), or it may be the first subtype of
2592 -- an anonymous base type (e.g. for integer type declarations or

2609 -- Defined in all entities. Set for generic formal subprograms.
2611 -- Is_For_Access_Subtype (Flag118)
2612 -- Defined in E_Private_Subtype and E_Record_Subtype entities. Means the
2613 -- sole purpose of the type is to be designated by an Access_Subtype and
2614 -- hence should not be expanded into components because the type may not
2615 -- have been found or frozen yet.
2617 -- Is_Frozen (Flag4)
2618 -- Defined in all type and subtype entities. Set if type or subtype has
2621 -- Is_Generic_Actual_Subprogram (Flag274)
2622 -- Defined on functions and procedures. Set on the entity of the renaming
2623 -- declaration created within an instance for an actual subprogram.
2624 -- Used to generate constraint checks on calls to these subprograms, even
2625 -- within an instance of a predefined run-time unit, in which checks
2626 -- are otherwise suppressed.
2628 -- The flag is also set on the entity of the expression function created
2629 -- within an instance, for a function that has external axiomatization,
2630 -- for use in GNATprove mode.
2632 -- Is_Generic_Actual_Type (Flag94)
2633 -- Defined in all type and subtype entities. Set in the subtype
2634 -- declaration that renames the generic formal as a subtype of the
2635 -- actual. Guarantees that the subtype is not static within the instance.
2636 -- Also used during analysis of an instance, to simplify resolution of
2637 -- accidental overloading that occurs when different formal types get the
2640 -- Is_Generic_Instance (Flag130)
2641 -- Defined in all entities. Set to indicate that the entity is an
2642 -- instance of a generic unit, or a formal package (which is an instance
2643 -- of the template).
2645 -- Is_Generic_Subprogram (synthesized)
2646 -- Applies to all entities. Yields True for a generic subprogram
2647 -- (generic function, generic subprogram), False for all other entities.
2649 -- Is_Generic_Type (Flag13)
2650 -- Defined in all entities. Set for types which are generic formal types.
2651 -- Such types have an Ekind that corresponds to their classification, so
2652 -- the Ekind cannot be used to identify generic formal types.
2654 -- Is_Generic_Unit (synthesized)
2655 -- Applies to all entities. Yields True for a generic unit (generic
2656 -- package, generic function, generic procedure), and False for all
2659 -- Is_Ghost_Entity (synthesized)
2660 -- Applies to all entities. Yields True for abstract states, [generic]
2661 -- packages, [generic] subprograms, components, discriminants, formal
2662 -- parameters, objects, package bodies, subprogram bodies, and [sub]types
2663 -- subject to pragma Ghost or those that inherit the Ghost propery from
2664 -- an enclosing construct.
2666 -- Is_Hidden (Flag57)
2667 -- Defined in all entities. Set for all entities declared in the
2668 -- private part or body of a package. Also marks generic formals of a
2669 -- formal package declared without a box. For library level entities,
2670 -- this flag is set if the entity is not publicly visible. This flag
2671 -- is reset when compiling the body of the package where the entity
2672 -- is declared, when compiling the private part or body of a public
2673 -- child unit, and when compiling a private child unit (see Install_
2674 -- Private_Declaration in sem_ch7).
2676 -- Is_Hidden_Non_Overridden_Subpgm (Flag2)
2677 -- Defined in all entities. Set for implicitly declared subprograms
2678 -- that require overriding or are null procedures, and are hidden by
2679 -- a non-fully conformant homograph with the same characteristics
2680 -- (Ada RM 8.3 12.3/2).
2682 -- Is_Hidden_Open_Scope (Flag171)
2683 -- Defined in all entities. Set for a scope that contains the
2684 -- instantiation of a child unit, and whose entities are not visible
2685 -- during analysis of the instance.
2687 -- Is_Ignored_Ghost_Entity (Flag278)
2688 -- Applies to all entities. Set for abstract states, [generic] packages,
2689 -- [generic] subprograms, components, discriminants, formal parameters,
2690 -- objects, package bodies, subprogram bodies, and [sub]types subject to
2691 -- pragma Ghost or inherit "ghostness" from an enclosing construct, and
2692 -- subject to Assertion_Policy Ghost => Ignore.
2694 -- Is_Ignored_Transient (Flag295)
2695 -- Defined in constants, loop parameters of generalized iterators, and
2696 -- variables. Set when a transient object must be processed by one of
2697 -- the transient finalization mechanisms. Once marked, a transient is
2698 -- intentionally ignored by the general finalization mechanism because
2699 -- its clean up actions are context specific.
2701 -- Is_Immediately_Visible (Flag7)
2702 -- Defined in all entities. Set if entity is immediately visible, i.e.
2703 -- is defined in some currently open scope (RM 8.3(4)).
2705 -- Is_Implementation_Defined (Flag254)
2706 -- Defined in all entities. Set if a pragma Implementation_Defined is
2707 -- applied to the pragma. Used to mark all implementation defined
2708 -- identifiers in standard library packages, and to implement the
2709 -- restriction No_Implementation_Identifiers.
2711 -- Is_Imported (Flag24)
2712 -- Defined in all entities. Set if the entity is imported. For now we
2713 -- only allow the import of exceptions, functions, procedures, packages,
2714 -- constants, and variables. Exceptions, packages, and types can only be
2715 -- imported in the Java VM implementation, which is retired.
2717 -- Is_Incomplete_Or_Private_Type (synthesized)
2718 -- Applies to all entities, true for private and incomplete types
2720 -- Is_Incomplete_Type (synthesized)
2721 -- Applies to all entities, true for incomplete types and subtypes
2723 -- Is_Independent (Flag268)
2724 -- Defined in all type entities, and also in constants, components and
2725 -- variables. Set if a valid pragma or aspect Independent applies to the
2726 -- entity, or if a valid pragma or aspect Independent_Components applies
2727 -- to the enclosing record type for a component. Also set if a pragma
2728 -- Shared or pragma Atomic applies to the entity. In the case of private
2729 -- and incomplete types, this flag is set in both the partial view and
2732 -- Is_Initial_Condition_Procedure (Flag302)
2733 -- Defined in functions and procedures. Set for a generated procedure
2734 -- which verifies the assumption of pragma Initial_Condition at run time.
2736 -- Is_Inlined (Flag11)
2737 -- Defined in all entities. Set for functions and procedures which are
2738 -- to be inlined. For subprograms created during expansion, this flag
2739 -- may be set directly by the expander to request inlining. Also set
2740 -- for packages that contain inlined subprograms, whose bodies must be
2741 -- be compiled. Is_Inlined is also set on generic subprograms and is
2742 -- inherited by their instances. It is also set on the body entities
2743 -- of inlined subprograms. See also Has_Pragma_Inline.
2745 -- Is_Inlined_Always (Flag1)
2746 -- Defined in subprograms. Set for functions and procedures which are
2747 -- always inlined in GNATprove mode. GNATprove uses this flag to know
2748 -- when a body does not need to be analyzed. The value of this flag is
2749 -- only meaningful if Body_To_Inline is not Empty for the subprogram.
2751 -- Is_Instantiated (Flag126)
2752 -- Defined in generic packages and generic subprograms. Set if the unit
2753 -- is instantiated from somewhere in the extended main source unit. This
2754 -- flag is used to control warnings about the unit being uninstantiated.
2755 -- Also set in a package that is used as an actual for a generic package
2756 -- formal in an instantiation. Also set on a parent instance, in the
2757 -- instantiation of a child, which is implicitly declared in the parent.
2759 -- Is_Integer_Type (synthesized)
2760 -- Applies to all entities, true for integer types and subtypes
2762 -- Is_Interface (Flag186)
2763 -- Defined in record types and subtypes. Set to indicate that the current
2764 -- entity corresponds to an abstract interface. Because abstract
2765 -- interfaces are conceptually a special kind of abstract tagged type
2766 -- we represent them by means of tagged record types and subtypes
2767 -- marked with this attribute. This allows us to reuse most of the
2768 -- compiler support for abstract tagged types to implement interfaces
2769 -- (Ada 2005: AI-251).
2771 -- Is_Internal (Flag17)
2772 -- Defined in all entities. Set to indicate an entity created during
2773 -- semantic processing (e.g. an implicit type, or a temporary). The
2774 -- current uses of this flag are:
2776 -- 1) Internal entities (such as temporaries generated for the result
2777 -- of an inlined function call or dummy variables generated for the
2778 -- debugger). Set to indicate that they need not be initialized, even
2779 -- when scalars are initialized or normalized.
2781 -- 2) Predefined primitives of tagged types. Set to mark that they
2782 -- have specific properties: first they are primitives even if they
2783 -- are not defined in the type scope (the freezing point is not
2784 -- necessarily in the same scope), and second the predefined equality
2785 -- can be overridden by a user-defined equality, no body will be
2786 -- generated in this case.
2788 -- 3) Object declarations generated by the expander that are implicitly
2789 -- imported or exported so that they can be marked in Sprint output.
2791 -- 4) Internal entities in the list of primitives of tagged types that
2792 -- are used to handle secondary dispatch tables. These entities have
2793 -- also the attribute Interface_Alias.
2795 -- Is_Interrupt_Handler (Flag89)
2796 -- Defined in procedures. Set if a pragma Interrupt_Handler applies
2797 -- to the procedure. The procedure must be parameterless, and on all
2798 -- targets except AAMP it must be a protected procedure.
2800 -- Is_Intrinsic_Subprogram (Flag64)
2801 -- Defined in functions and procedures. It is set if a valid pragma
2802 -- Interface or Import is present for this subprogram specifying
2803 -- convention Intrinsic. Valid means that the name and profile of the
2804 -- subprogram match the requirements of one of the recognized intrinsic
2805 -- subprograms (see package Sem_Intr for details). Note: the value of
2806 -- Convention for such an entity will be set to Convention_Intrinsic,
2807 -- but it is the setting of Is_Intrinsic_Subprogram, NOT simply having
2808 -- convention set to intrinsic, which causes intrinsic code to be
2811 -- Is_Invariant_Procedure (Flag257)
2812 -- Defined in functions and procedures. Set for a generated invariant
2813 -- procedure which verifies the invariants of both the partial and full
2814 -- views of a private type or private extension as well as any inherited
2815 -- class-wide invariants from parent types or interfaces.
2817 -- Is_Itype (Flag91)
2818 -- Defined in all entities. Set to indicate that a type is an Itype,
2819 -- which means that the declaration for the type does not appear
2820 -- explicitly in the tree. Instead the backend will elaborate the type
2821 -- when it is first used. Has_Delayed_Freeze can be set for Itypes, and
2822 -- the meaning is that the first use (the one which causes the type to be
2823 -- defined) will be the freeze node. Note that an important restriction
2824 -- on Itypes is that the first use of such a type (the one that causes it
2825 -- to be defined) must be in the same scope as the type.
2827 -- Is_Known_Non_Null (Flag37)
2828 -- Defined in all entities. Relevant (and can be set) only for
2829 -- objects of an access type. It is set if the object is currently
2830 -- known to have a non-null value (meaning that no access checks
2831 -- are needed). The indication can for example come from assignment
2832 -- of an access parameter or an allocator whose value is known non-null.
2834 -- Note: this flag is set according to the sequential flow of the
2835 -- program, watching the current value of the variable. However, this
2836 -- processing can miss cases of changing the value of an aliased or
2837 -- constant object, so even if this flag is set, it should not be
2838 -- believed if the variable is aliased or volatile. It would be a
2839 -- little neater to avoid the flag being set in the first place in
2840 -- such cases, but that's trickier, and there is only one place that
2841 -- tests the value anyway.
2843 -- The flag is dynamically set and reset as semantic analysis and
2844 -- expansion proceeds. Its value is meaningless once the tree is
2845 -- fully constructed, since it simply indicates the last state.
2846 -- Thus this flag has no meaning to the backend.
2848 -- Is_Known_Null (Flag204)
2849 -- Defined in all entities. Relevant (and can be set ) only for
2850 -- objects of an access type. It is set if the object is currently known
2851 -- to have a null value (meaning that a dereference will surely raise
2852 -- constraint error exception). The indication can come from an
2853 -- assignment or object declaration.
2855 -- The comments above about sequential flow and aliased and volatile for
2856 -- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag.
2858 -- Is_Known_Valid (Flag170)
2859 -- Defined in all entities. Relevant for types (and subtype) and
2860 -- for objects (and enumeration literals) of a discrete type.
2862 -- The purpose of this flag is to implement the requirement stated
2863 -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
2864 -- values may not cause programs to become erroneous. See the function
2865 -- Checks.Expr_Known_Valid for further details. Note that the setting
2866 -- is conservative, in the sense that if the flag is set, it must be
2867 -- right. If the flag is not set, nothing is known about the validity.
2869 -- For enumeration literals, the flag is always set, since clearly
2870 -- an enumeration literal represents a valid value. Range checks
2871 -- where necessary will ensure that this valid value is appropriate.
2873 -- For objects, the flag indicates the state of knowledge about the
2874 -- current value of the object. This may be modified during expansion,
2875 -- and thus the final value is not relevant to the backend.
2877 -- For types and subtypes, the flag is set if all possible bit patterns
2878 -- of length Object_Size (i.e. Esize of the type) represent valid values
2879 -- of the type. In general for such types, all values are valid, the
2880 -- only exception being the case where an object of the type has an
2881 -- explicit size that is greater than Object_Size.
2883 -- For non-discrete objects, the setting of the Is_Known_Valid flag is
2884 -- not defined, and is not relevant, since the considerations of the
2885 -- requirement in (RM 13.9.1(9-11)) do not apply.
2887 -- The flag is dynamically set and reset as semantic analysis and
2888 -- expansion proceeds. Its value is meaningless once the tree is
2889 -- fully constructed, since it simply indicates the last state.
2890 -- Thus this flag has no meaning to the backend.
2892 -- Is_Limited_Composite (Flag106)
2893 -- Defined in all entities. Set for composite types that have a limited
2894 -- component. Used to enforce the rule that operations on the composite
2895 -- type that depend on the full view of the component do not become
2896 -- visible until the immediate scope of the composite type itself
2899 -- Is_Limited_Interface (Flag197)
2900 -- Defined in record types and subtypes. True for interface types, if
2901 -- interface is declared limited, task, protected, or synchronized, or
2902 -- is derived from a limited interface.
2904 -- Is_Limited_Record (Flag25)
2905 -- Defined in all entities. Set to true for record (sub)types if the
2906 -- record is declared to be limited. Note that this flag is not set
2907 -- simply because some components of the record are limited.
2909 -- Is_Local_Anonymous_Access (Flag194)
2910 -- Defined in access types. Set for an anonymous access type to indicate
2911 -- that the type is created for a record component with an access
2912 -- definition, an array component, or (pre-Ada 2012) a standalone object.
2913 -- Such anonymous types have an accessibility level equal to that of the
2914 -- declaration in which they appear, unlike the anonymous access types
2915 -- that are created for access parameters, access discriminants, and
2916 -- (as of Ada 2012) stand-alone objects.
2918 -- Is_Machine_Code_Subprogram (Flag137)
2919 -- Defined in subprogram entities. Set to indicate that the subprogram
2920 -- is a machine code subprogram (i.e. its body includes at least one
2921 -- code statement). Also indicates that all necessary semantic checks
2922 -- as required by RM 13.8(3) have been performed.
2924 -- Is_Modular_Integer_Type (synthesized)
2925 -- Applies to all entities. True if entity is a modular integer type
2927 -- Is_Non_Static_Subtype (Flag109)
2928 -- Defined in all type and subtype entities. It is set in some (but not
2929 -- all) cases in which a subtype is known to be non-static. Before this
2930 -- flag was added, the computation of whether a subtype was static was
2931 -- entirely synthesized, by looking at the bounds, and the immediate
2932 -- subtype parent. However, this method does not work for some Itypes
2933 -- that have no parent set (and the only way to find the immediate
2934 -- subtype parent is to go through the tree). For now, this flag is set
2935 -- conservatively, i.e. if it is set then for sure the subtype is non-
2936 -- static, but if it is not set, then the type may or may not be static.
2937 -- Thus the test for a static subtype is that this flag is clear AND that
2938 -- the bounds are static AND that the parent subtype (if available to be
2939 -- tested) is static. Eventually we should make sure this flag is always
2940 -- set right, at which point, these comments can be removed, and the
2941 -- tests for static subtypes greatly simplified.
2943 -- Is_Null_Init_Proc (Flag178)
2944 -- Defined in procedure entities. Set for generated init proc procedures
2945 -- (used to initialize composite types), if the code for the procedure
2946 -- is null (i.e. is a return and nothing else). Such null initialization
2947 -- procedures are generated in case some client is compiled using the
2948 -- Initialize_Scalars pragma, generating a call to this null procedure,
2949 -- but there is no need to call such procedures within a compilation
2950 -- unit, and this flag is used to suppress such calls.
2952 -- Is_Null_State (synthesized)
2953 -- Applies to all entities, true for an abstract state declared with
2956 -- Is_Numeric_Type (synthesized)
2957 -- Applies to all entities, true for all numeric types and subtypes
2958 -- (integer, fixed, float).
2960 -- Is_Object (synthesized)
2961 -- Applies to all entities, true for entities representing objects,
2962 -- including generic formal parameters.
2964 -- Is_Obsolescent (Flag153)
2965 -- Defined in all entities. Set for any entity to which a valid pragma
2966 -- or aspect Obsolescent applies.
2968 -- Is_Only_Out_Parameter (Flag226)
2969 -- Defined in formal parameter entities. Set if this parameter is the
2970 -- only OUT parameter for this formal part. If there is more than one
2971 -- out parameter, or if there is some other IN OUT parameter then this
2972 -- flag is not set in any of them. Used in generation of warnings.
2974 -- Is_Ordinary_Fixed_Point_Type (synthesized)
2975 -- Applies to all entities, true for ordinary fixed point types and
2978 -- Is_Package_Body_Entity (Flag160)
2979 -- Defined in all entities. Set for entities defined at the top level
2980 -- of a package body. Used to control externally generated names.
2982 -- Is_Package_Or_Generic_Package (synthesized)
2983 -- Applies to all entities. True for packages and generic packages.
2984 -- False for all other entities.
2986 -- Is_Packed (Flag51) [implementation base type only]
2987 -- Defined in all type entities. This flag is set only for record and
2988 -- array types which have a packed representation. There are four cases
2989 -- which cause packing:
2991 -- 1. Explicit use of pragma Pack to pack a record.
2992 -- 2. Explicit use of pragma Pack to pack an array.
2993 -- 3. Setting Component_Size of an array to a packable value.
2994 -- 4. Indexing an array with a non-standard enumeration type.
2996 -- For records, Is_Packed is always set if Has_Pragma_Pack is set, and
2997 -- can also be set on its own in a derived type which inherited its
3000 -- For arrays, Is_Packed is set if either Has_Pragma_Pack is set and the
3001 -- component size is either not known at compile time or known but not
3002 -- 8/16/32/64 bits, or a Component_Size clause exists and the specified
3003 -- value is smaller than 64 bits but not 8/16/32, or if the array has one
3004 -- or more index types that are enumeration types with a non-standard
3005 -- representation (in GNAT, we store such arrays compactly, using the Pos
3006 -- of the enumeration type value). As for the case of records, Is_Packed
3007 -- can be set on its own for a derived type.
3009 -- Before an array type is frozen, Is_Packed will always be set if
3010 -- Has_Pragma_Pack is set. Before the freeze point, it is not possible
3011 -- to know the component size, since the component type is not frozen
3012 -- until the array type is frozen. Thus Is_Packed for an array type
3013 -- before it is frozen means that packed is required. Then if it turns
3014 -- out that the component size doesn't require packing, the Is_Packed
3015 -- flag gets turned off.
3017 -- In the bit-packed array case (i.e. component size is known at compile
3018 -- time and is 1-7, 9-15, 17-31 or 33-63), Is_Bit_Packed_Array will be
3019 -- set once the array type is frozen.
3021 -- Is_Packed_Array (synth)
3022 -- Applies to all entities, true if entity is for a packed array.
3024 -- Is_Packed_Array_Impl_Type (Flag138)
3025 -- Defined in all entities. This flag is set on the entity for the type
3026 -- used to implement a packed array (either a modular type or a subtype
3027 -- of Packed_Bytes{1,2,4} in the bit-packed array case, a regular array
3028 -- in the non-standard enumeration index case). It is set if and only
3029 -- if the type appears in the Packed_Array_Impl_Type field of some other
3030 -- entity. It is used by the back end to activate the special processing
3031 -- for such types (unchecked conversions that would not otherwise be
3032 -- allowed are allowed for such types). If Is_Packed_Array_Impl_Type is
3033 -- set in an entity, then the Original_Array_Type field of this entity
3034 -- points to the array type for which this is the Packed_Array_Impl_Type.
3036 -- Is_Param_Block_Component_Type (Flag215) [base type only]
3037 -- Defined in access types. Set to indicate that a type is the type of a
3038 -- component of the parameter block record type generated by the compiler
3039 -- for an entry or a select statement. Read by CodePeer.
3041 -- Is_Partial_Invariant_Procedure (Flag292)
3042 -- Defined in functions and procedures. Set for a generated invariant
3043 -- procedure which verifies the invariants of the partial view of a
3044 -- private type or private extension.
3046 -- Is_Potentially_Use_Visible (Flag9)
3047 -- Defined in all entities. Set if entity is potentially use visible,
3048 -- i.e. it is defined in a package that appears in a currently active
3049 -- use clause (RM 8.4(8)). Note that potentially use visible entities
3050 -- are not necessarily use visible (RM 8.4(9-11)).
3052 -- Is_Predicate_Function (Flag255)
3053 -- Present in functions and procedures. Set for generated predicate
3056 -- Is_Predicate_Function_M (Flag256)
3057 -- Present in functions and procedures. Set for special version of
3058 -- predicate function generated for use in membership tests, where
3059 -- raise expressions are transformed to return False.
3061 -- Is_Preelaborated (Flag59)
3062 -- Defined in all entities, set in E_Package and E_Generic_Package
3063 -- entities to which a pragma Preelaborate is applied, and also in
3064 -- all entities within such packages. Note that the fact that this
3065 -- flag is set does not necesarily mean that no elaboration code is
3066 -- generated for the package.
3068 -- Is_Primitive (Flag218)
3069 -- Defined in overloadable entities and in generic subprograms. Set to
3070 -- indicate that this is a primitive operation of some type, which may
3071 -- be a tagged type or an untagged type. Used to verify overriding
3072 -- indicators in bodies.
3074 -- Is_Primitive_Wrapper (Flag195)
3075 -- Defined in functions and procedures created by the expander to serve
3076 -- as an indirection mechanism to overriding primitives of concurrent
3077 -- types, entries and protected procedures.
3079 -- Is_Prival (synthesized)
3080 -- Applies to all entities, true for renamings of private protected
3081 -- components. Such entities appear as constants or variables.
3083 -- Is_Private_Composite (Flag107)
3084 -- Defined in composite types that have a private component. Used to
3085 -- enforce the rule that operations on the composite type that depend
3086 -- on the full view of the component, do not become visible until the
3087 -- immediate scope of the composite type itself (7.3.1 (5)). Both this
3088 -- flag and Is_Limited_Composite are needed.
3090 -- Is_Private_Descendant (Flag53)
3091 -- Defined in entities that can represent library units (packages,
3092 -- functions, procedures). Set if the library unit is itself a private
3093 -- child unit, or if it is the descendant of a private child unit.
3095 -- Is_Private_Primitive (Flag245)
3096 -- Defined in subprograms. Set if the operation is a primitive of a
3097 -- tagged type (procedure or function dispatching on result) whose
3098 -- full view has not been seen. Used in particular for primitive
3099 -- subprograms of a synchronized type declared between the two views
3100 -- of the type, so that the wrapper built for such a subprogram can
3101 -- be given the proper signature.
3103 -- Is_Private_Type (synthesized)
3104 -- Applies to all entities, true for private types and subtypes,
3105 -- as well as for record with private types as subtypes.
3107 -- Is_Protected_Component (synthesized)
3108 -- Applicable to all entities, true if the entity denotes a private
3109 -- component of a protected type.
3111 -- Is_Protected_Interface (synthesized)
3112 -- Defined in types that are interfaces. True if interface is declared
3113 -- protected, or is derived from protected interfaces.

3117 -- Corresponding_Concurrent_Type is a protected type.
3119 -- Is_Protected_Type (synthesized)
3120 -- Applies to all entities, true for protected types and subtypes
3122 -- Is_Public (Flag10)
3123 -- Defined in all entities. Set to indicate that an entity defined in
3124 -- one compilation unit can be referenced from other compilation units.
3125 -- If this reference causes a reference in the generated code, for
3126 -- example in the case of a variable name, then the backend will generate
3127 -- an appropriate external name for use by the linker.
3130 -- Defined in all entities. Set in all entities of a unit to which a
3131 -- pragma Pure is applied except for non-intrinsic imported subprograms,
3132 -- and also set for the entity of the unit itself. In addition, this
3133 -- flag may be set for any other functions or procedures that are known
3134 -- to be side effect free, so in the case of subprograms, the Is_Pure
3135 -- flag may be used by the optimizer to imply that it can assume freedom
3136 -- from side effects (other than those resulting from assignment to out
3137 -- parameters, or to objects designated by access parameters).
3139 -- Is_Pure_Unit_Access_Type (Flag189)
3140 -- Defined in access type and subtype entities. Set if the type or
3141 -- subtype appears in a pure unit. Used to give an error message at
3142 -- freeze time if the access type has a storage pool.
3144 -- Is_RACW_Stub_Type (Flag244)
3145 -- Defined in all types, true for the stub types generated for remote
3146 -- access-to-class-wide types.
3148 -- Is_Raised (Flag224)
3149 -- Defined in exception entities. Set if the entity is referenced by a
3150 -- a raise statement.
3152 -- Is_Real_Type (synthesized)
3153 -- Applies to all entities, true for real types and subtypes
3155 -- Is_Record_Type (synthesized)
3156 -- Applies to all entities, true for record types and subtypes,
3157 -- includes class-wide types and subtypes (which are also records).
3159 -- Is_Remote_Call_Interface (Flag62)
3160 -- Defined in all entities. Set in E_Package and E_Generic_Package
3161 -- entities to which a pragma Remote_Call_Interface is applied, and
3162 -- also on entities declared in the visible part of such a package.
3164 -- Is_Remote_Types (Flag61)
3165 -- Defined in all entities. Set in E_Package and E_Generic_Package
3166 -- entities to which a pragma Remote_Types is applied, and also on
3167 -- entities declared in the visible part of the spec of such a package.
3168 -- Also set for types which are generic formal types to which the
3169 -- pragma Remote_Access_Type applies.
3171 -- Is_Renaming_Of_Object (Flag112)
3172 -- Defined in all entities, set only for a variable or constant for
3173 -- which the Renamed_Object field is non-empty and for which the
3174 -- renaming is handled by the front end, by macro substitution of
3175 -- a copy of the (evaluated) name tree whereever the variable is used.
3177 -- Is_Return_Object (Flag209)
3178 -- Defined in all object entities. True if the object is the return
3179 -- object of an extended_return_statement; False otherwise.
3181 -- Is_Safe_To_Reevaluate (Flag249)
3182 -- Defined in all entities. Set in variables that are initialized by
3183 -- means of an assignment statement. When initialized their contents
3184 -- never change and hence they can be seen by the backend as constants.
3185 -- See also Is_True_Constant.
3187 -- Is_Scalar_Type (synthesized)
3188 -- Applies to all entities, true for scalar types and subtypes
3190 -- Is_Shared_Passive (Flag60)
3191 -- Defined in all entities. Set in E_Package and E_Generic_Package
3192 -- entities to which a pragma Shared_Passive is applied, and also in
3193 -- all entities within such packages.
3195 -- Is_Standard_Character_Type (synthesized)
3196 -- Applies to all entities, true for types and subtypes whose root type
3197 -- is one of the standard character types (Character, Wide_Character, or
3198 -- Wide_Wide_Character).
3200 -- Is_Standard_String_Type (synthesized)
3201 -- Applies to all entities, true for types and subtypes whose root
3202 -- type is one of the standard string types (String, Wide_String, or
3203 -- Wide_Wide_String).
3205 -- Is_Static_Type (Flag281)
3206 -- Defined in entities. Only set for (sub)types. If set, indicates that
3207 -- the type is known to be a static type (defined as a discrete type with
3208 -- static bounds, a record all of whose component types are static types,
3209 -- or an array, all of whose bounds are of a static type, and also have
3210 -- a component type that is a static type). See Set_Uplevel_Type for more
3211 -- information on how this flag is used.
3213 -- Is_Statically_Allocated (Flag28)
3214 -- Defined in all entities. This can only be set for exception,
3215 -- variable, constant, and type/subtype entities. If the flag is set,
3216 -- then the variable or constant must be allocated statically rather
3217 -- than on the local stack frame. For exceptions, the meaning is that
3218 -- the exception data should be allocated statically (and indeed this
3219 -- flag is always set for exceptions, since exceptions do not have
3220 -- local scope). For a type, the meaning is that the type must be
3221 -- elaborated at the global level rather than locally. No type marked
3222 -- with this flag may depend on a local variable, or on any other type
3223 -- which does not also have this flag set to True. For a variable or
3224 -- or constant, if the flag is set, then the type of the object must
3225 -- either be declared at the library level, or it must also have the
3226 -- flag set (since to allocate the object statically, its type must
3227 -- also be elaborated globally).
3229 -- Is_String_Type (synthesized)
3230 -- Applies to all type entities. Determines if the given type is a
3231 -- string type, i.e. it is directly a string type or string subtype,
3232 -- or a string slice type, or an array type with one dimension and a
3233 -- component type that is a character type.
3235 -- Is_Subprogram (synthesized)
3236 -- Applies to all entities, true for function, procedure and operator
3239 -- Is_Subprogram_Or_Generic_Subprogram
3240 -- Applies to all entities, true for function procedure and operator
3241 -- entities, and also for the corresponding generic entities.
3243 -- Is_Synchronized_Interface (synthesized)
3244 -- Defined in types that are interfaces. True if interface is declared
3245 -- synchronized, task, or protected, or is derived from a synchronized
3248 -- Is_Synchronized_State (synthesized)
3249 -- Applies to all entities, true for abstract states that are subject to
3250 -- option Synchronous.
3253 -- Defined in E_Component and E_Constant entities. For regular tagged
3254 -- type this flag is set on the tag component (whose name is Name_uTag).
3255 -- For CPP_Class tagged types, this flag marks the pointer to the main
3256 -- vtable (i.e. the one to be extended by derivation).
3258 -- Is_Tagged_Type (Flag55)
3259 -- Defined in all entities, set for an entity that is a tagged type
3261 -- Is_Task_Interface (synthesized)
3262 -- Defined in types that are interfaces. True if interface is declared as
3263 -- a task interface, or if it is derived from task interfaces.
3265 -- Is_Task_Record_Type (synthesized)
3266 -- Applies to all entities. True if Is_Concurrent_Record_Type
3267 -- Corresponding_Concurrent_Type is a task type.
3269 -- Is_Task_Type (synthesized)
3270 -- Applies to all entities. True for task types and subtypes
3272 -- Is_Thunk (Flag225)
3273 -- Defined in all entities. True for subprograms that are thunks: that is
3274 -- small subprograms built by the expander for tagged types that cover
3275 -- interface types. As part of the runtime call to an interface, thunks
3276 -- displace the pointer to the object (pointer named "this" in the C++
3277 -- terminology) from a secondary dispatch table to the primary dispatch
3278 -- table associated with a given tagged type; if the thunk is a function
3279 -- that returns an object which covers an interface type then the thunk
3280 -- displaces the pointer to the object from the primary dispatch table to
3281 -- the secondary dispatch table associated with the interface type. Set
3282 -- by Expand_Interface_Thunk and used by Expand_Call to handle extra
3283 -- actuals associated with accessibility level.
3285 -- Is_Trivial_Subprogram (Flag235)
3286 -- Defined in all entities. Set in subprograms where either the body
3287 -- consists of a single null statement, or the first or only statement
3288 -- of the body raises an exception. This is used for suppressing certain
3289 -- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details.
3291 -- Is_True_Constant (Flag163)
3292 -- Defined in all entities for constants and variables. Set in constants
3293 -- and variables which have an initial value specified but which are
3294 -- never assigned, partially or in the whole. For variables, it means
3295 -- that the variable was initialized but never modified, and hence can be
3296 -- treated as a constant by the code generator. For a constant, it means
3297 -- that the constant was not modified by generated code (e.g. to set a
3298 -- discriminant in an init proc). Assignments by user or generated code
3299 -- will reset this flag. See also Is_Safe_To_Reevaluate.
3301 -- Is_Type (synthesized)
3302 -- Applies to all entities, true for a type entity
3304 -- Is_Unchecked_Union (Flag117) [implementation base type only]
3305 -- Defined in all entities. Set only in record types to which the
3306 -- pragma Unchecked_Union has been validly applied.
3308 -- Is_Underlying_Full_View (Flag298)
3309 -- Defined in all entities. Set for types which represent the true full
3310 -- view of a private type completed by another private type. For further
3311 -- details, see attribute Underlying_Full_View.
3313 -- Is_Underlying_Record_View (Flag246) [base type only]
3314 -- Defined in all entities. Set only in record types that represent the
3315 -- underlying record view. This view is built for derivations of types
3316 -- with unknown discriminants; it is a record with the same structure
3317 -- as its corresponding record type, but whose parent is the full view
3318 -- of the parent in the original type extension.
3320 -- Is_Unimplemented (Flag284)
3321 -- Defined in all entities. Set for any entity to which a valid pragma
3322 -- or aspect Unimplemented applies.
3324 -- Is_Unsigned_Type (Flag144)
3325 -- Defined in all types, but can be set only for discrete and fixed-point
3326 -- type and subtype entities. This flag is only valid if the entity is
3327 -- frozen. If set it indicates that the representation is known to be
3328 -- unsigned (i.e. that no negative values appear in the range). This is
3329 -- normally just a reflection of the lower bound of the subtype or base
3330 -- type, but there is one case in which the setting is non-obvious,
3331 -- namely the case of an unsigned subtype of a signed type from which
3332 -- a further subtype is obtained using variable bounds. This further
3333 -- subtype is still unsigned, but this cannot be determined by looking
3334 -- at its bounds or the bounds of the corresponding base type.
3336 -- Is_Uplevel_Referenced_Entity (Flag283)
3337 -- Defined in all entities. Used when unnesting subprograms to indicate
3338 -- that an entity is locally defined within a subprogram P, and there is
3339 -- a reference to the entity within a subprogram nested within P (at any
3340 -- depth). Set for uplevel referenced objects (variables, constants,
3341 -- discriminants and loop parameters), and also for upreferenced dynamic
3342 -- types, including the cases where the reference is implicit (e.g. the
3343 -- type of an array used for computing the location of an element in an
3344 -- array. This is used internally in Exp_Unst, see this package for
3347 -- Is_Valued_Procedure (Flag127)
3348 -- Defined in procedure entities. Set if an Import_Valued_Procedure
3349 -- or Export_Valued_Procedure pragma applies to the procedure entity.
3351 -- Is_Visible_Formal (Flag206)
3352 -- Defined in all entities. Set for instances of the formals of a
3353 -- formal package. Indicates that the entity must be made visible in the
3354 -- body of the instance, to reproduce the visibility of the generic.
3355 -- This simplifies visibility settings in instance bodies.
3357 -- Is_Visible_Lib_Unit (Flag116)
3358 -- Defined in all (root or child) library unit entities. Once compiled,
3359 -- library units remain chained to the entities in the parent scope, and
3360 -- a separate flag must be used to indicate whether the names are visible
3361 -- by selected notation, or not.
3363 -- Is_Volatile (Flag16)
3364 -- Defined in all type entities, and also in constants, components and
3365 -- variables. Set if a pragma Volatile applies to the entity. Also set
3366 -- if pragma Shared or pragma Atomic applies to entity. In the case of
3367 -- private or incomplete types, this flag is set in both the private
3368 -- and full view. The flag is not set reliably on private subtypes,
3369 -- and is always retrieved from the base type (but this is not a base-
3370 -- type-only attribute because it applies to other entities). Note that
3371 -- the backend should use Treat_As_Volatile, rather than Is_Volatile
3372 -- to indicate code generation requirements for volatile variables.
3373 -- Similarly, any front end test which is concerned with suppressing
3374 -- optimizations on volatile objects should test Treat_As_Volatile
3375 -- rather than testing this flag.
3377 -- Is_Volatile_Full_Access (Flag285)
3378 -- Defined in all type entities, and also in constants, components, and
3379 -- variables. Set if a pragma Volatile_Full_Access applies to the entity.
3380 -- In the case of private and incomplete types, this flag is set in
3381 -- both the partial view and the full view.
3383 -- Is_Wrapper_Package (synthesized)
3384 -- Defined in package entities. Indicates that the package has been
3385 -- created as a wrapper for a subprogram instantiation.
3387 -- Itype_Printed (Flag202)
3388 -- Defined in all type and subtype entities. Set in Itypes if the Itype
3389 -- has been printed by Sprint. This is used to avoid printing an Itype
3392 -- Kill_Elaboration_Checks (Flag32)
3393 -- Defined in all entities. Set by the expander to kill elaboration
3394 -- checks which are known not to be needed. Equivalent in effect to
3395 -- the use of pragma Suppress (Elaboration_Checks) for that entity
3396 -- except that the effect is permanent and cannot be undone by a
3397 -- subsequent pragma Unsuppress.
3399 -- Kill_Range_Checks (Flag33)
3400 -- Defined in all entities. Equivalent in effect to the use of pragma
3401 -- Suppress (Range_Checks) for that entity except that the result is
3402 -- permanent and cannot be undone by a subsequent pragma Unsuppress.
3403 -- This is currently only used in one odd situation in Sem_Ch3 for
3404 -- record types, and it would be good to get rid of it???
3406 -- Known_To_Have_Preelab_Init (Flag207)
3407 -- Defined in all type and subtype entities. If set, then the type is
3408 -- known to have preelaborable initialization. In the case of a partial
3409 -- view of a private type, it is only possible for this to be set if a
3410 -- pragma Preelaborable_Initialization is given for the type. For other
3411 -- types, it is never set if the type does not have preelaborable
3412 -- initialization, it may or may not be set if the type does have
3413 -- preelaborable initialization.
3415 -- Last_Aggregate_Assignment (Node30)
3416 -- Applies to controlled constants and variables initialized by an
3417 -- aggregate. Points to the last statement associated with the expansion
3418 -- of the aggregate. The attribute is used by the finalization machinery
3419 -- when marking an object as successfully initialized.
3421 -- Last_Assignment (Node26)
3422 -- Defined in entities for variables, and OUT or IN OUT formals. Set for
3423 -- a local variable or formal to point to the left side of an assignment
3424 -- statement assigning a value to the variable. Cleared if the value of
3425 -- the entity is referenced. Used to warn about dubious assignment
3426 -- statements whose value is not used.
3428 -- Last_Entity (Node20)
3429 -- Defined in all entities which act as scopes to which a list of
3430 -- associated entities is attached (blocks, class subtypes and types,
3431 -- entries, functions, loops, packages, procedures, protected objects,
3432 -- record types and subtypes, private types, task types and subtypes).
3433 -- Points to the last entry in the list of associated entities chained
3434 -- through the Next_Entity field. Empty if no entities are chained.
3436 -- Last_Formal (synthesized)
3437 -- Applies to subprograms and subprogram types, and also in entries
3438 -- and entry families. Returns last formal of the subprogram or entry.
3439 -- The formals are the first entities declared in a subprogram or in
3440 -- a subprogram type (the designated type of an Access_To_Subprogram
3441 -- definition) or in an entry.
3443 -- Limited_View (Node23)
3444 -- Defined in non-generic package entities that are not instances. Bona
3445 -- fide package with the limited-view list through the first_entity and
3446 -- first_private attributes. The elements of this list are the shadow
3447 -- entities created for the types and local packages that are declared
3448 -- in a package appearing in a limited_with clause (Ada 2005: AI-50217).
3450 -- Linker_Section_Pragma (Node33)
3451 -- Present in constant, variable, type and subprogram entities. Points
3452 -- to a linker section pragma that applies to the entity, or is Empty if
3453 -- no such pragma applies. Note that for constants and variables, this
3454 -- field may be set as a result of a linker section pragma applied to the
3455 -- type of the object.
3457 -- Lit_Indexes (Node18)
3458 -- Defined in enumeration types and subtypes. Non-empty only for the
3459 -- case of an enumeration root type, where it contains the entity for
3460 -- the generated indexes entity. See unit Exp_Imgv for full details of
3461 -- the nature and use of this entity for implementing the Image and
3462 -- Value attributes for the enumeration type in question.
3464 -- Lit_Strings (Node16)
3465 -- Defined in enumeration types and subtypes. Non-empty only for the
3466 -- case of an enumeration root type, where it contains the entity for
3467 -- the literals string entity. See unit Exp_Imgv for full details of
3468 -- the nature and use of this entity for implementing the Image and
3469 -- Value attributes for the enumeration type in question.
3471 -- Low_Bound_Tested (Flag205)
3472 -- Defined in all entities. Currently this can only be set for formal
3473 -- parameter entries of a standard unconstrained one-dimensional array
3474 -- or string type. Indicates that an explicit test of the low bound of
3475 -- the formal appeared in the code, e.g. in a pragma Assert. If this
3476 -- flag is set, warnings about assuming the index low bound to be one
3479 -- Machine_Radix_10 (Flag84)
3480 -- Defined in decimal types and subtypes, set if the Machine_Radix is 10,
3481 -- as the result of the specification of a machine radix representation
3482 -- clause. Note that it is possible for this flag to be set without
3483 -- having Has_Machine_Radix_Clause True. This happens when a type is
3484 -- derived from a type with a clause present.
3486 -- Master_Id (Node17)
3487 -- Defined in access types and subtypes. Empty unless Has_Task is set for
3488 -- the designated type, in which case it points to the entity for the
3489 -- Master_Id for the access type master. Also set for access-to-limited-
3490 -- class-wide types whose root may be extended with task components, and
3491 -- for access-to-limited-interfaces because they can be used to reference
3492 -- tasks implementing such interface.
3494 -- Materialize_Entity (Flag168)
3495 -- Defined in all entities. Set only for renamed obects which should be
3496 -- materialized for debugging purposes. This means that a memory location
3497 -- containing the renamed address should be allocated. This is needed so
3498 -- that the debugger can find the entity.
3500 -- May_Inherit_Delayed_Rep_Aspects (Flag262)
3501 -- Defined in all entities for types and subtypes. Set if the type is
3502 -- derived from a type which has delayed rep aspects (marked by the flag
3503 -- Has_Delayed_Rep_Aspects being set). In this case, at the freeze point
3504 -- for the derived type we know that the parent type is frozen, and if
3505 -- a given attribute has not been set for the derived type, we copy the
3506 -- value from the parent type. See Freeze.Inherit_Delayed_Rep_Aspects.
3508 -- Mechanism (Uint8) (returned as Mechanism_Type)
3509 -- Defined in functions and non-generic formal parameters. Indicates
3510 -- the mechanism to be used for the function return or for the formal
3511 -- parameter. See full description in the spec of Sem_Mech. This field
3512 -- is also set (to the default value of zero = Default_Mechanism) in a
3513 -- subprogram body entity but not used in this context.
3515 -- Modulus (Uint17) [base type only]
3516 -- Defined in modular types. Contains the modulus. For the binary case,
3517 -- this will be a power of 2, but if Non_Binary_Modulus is set, then it
3518 -- will not be a power of 2.
3520 -- Must_Be_On_Byte_Boundary (Flag183)
3521 -- Defined in entities for types and subtypes. Set if objects of the type
3522 -- must always be allocated on a byte boundary (more accurately a storage
3523 -- unit boundary). The front end checks that component clauses respect
3524 -- this rule, and the backend ensures that record packing does not
3525 -- violate this rule. Currently the flag is set only for packed arrays
3526 -- longer than 64 bits where the component size is not a power of 2.
3528 -- Must_Have_Preelab_Init (Flag208)
3529 -- Defined in entities for types and subtypes. Set in the full type of a
3530 -- private type or subtype if a pragma Has_Preelaborable_Initialization
3531 -- is present for the private type. Used to check that the full type has
3532 -- preelaborable initialization at freeze time (this has to be deferred
3533 -- to the freeze point because of the rule about overriding Initialize).
3535 -- Needs_Activation_Record (Flag306)
3536 -- Defined on generated subprogram types. Indicates that a call through
3537 -- a named or anonymous access to subprogram requires an activation
3538 -- record when compiling with unnesting for C or LLVM.
3540 -- Needs_Debug_Info (Flag147)
3541 -- Defined in all entities. Set if the entity requires normal debugging
3542 -- information to be generated. This is true of all entities that have
3543 -- Comes_From_Source set, and also transitively for entities associated
3544 -- with such components (e.g. their types). It is true for all entities
3545 -- in Debug_Generated_Code mode (-gnatD switch). This is the flag that
3546 -- the backend should check to determine whether or not to generate
3547 -- debugging information for an entity. Note that callers should always
3548 -- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info,
3549 -- so that the flag is set properly on subsidiary entities.
3551 -- Needs_No_Actuals (Flag22)
3552 -- Defined in callable entities (subprograms, entries, access to
3553 -- subprograms) which can be called without actuals because all of
3554 -- their formals (if any) have default values. This flag simplifies the
3555 -- resolution of the syntactic ambiguity involving a call to these
3556 -- entities when the return type is an array type, and a call can be
3557 -- interpreted as an indexing of the result of the call. It is also
3558 -- used to resolve various cases of entry calls.
3560 -- Never_Set_In_Source (Flag115)
3561 -- Defined in all entities, but can be set only for variables and
3562 -- parameters. This flag is set if the object is never assigned a value
3563 -- in user source code, either by assignment or by being used as an out
3564 -- or in out parameter. Note that this flag is not reset from using an
3565 -- initial value, so if you want to test for this case as well, test the
3566 -- Has_Initial_Value flag also.
3568 -- This flag is only for the purposes of issuing warnings, it must not
3569 -- be used by the code generator to indicate that the variable is in
3570 -- fact a constant, since some assignments in generated code do not
3571 -- count (for example, the call to an init proc to assign some but
3572 -- not all of the fields in a partially initialized record). The code
3573 -- generator should instead use the flag Is_True_Constant.
3575 -- For the purposes of this warning, the default assignment of access
3576 -- variables to null is not considered the assignment of a value (so
3577 -- the warning can be given for code that relies on this initial null
3578 -- value when no other value is ever set).
3580 -- In variables and out parameters, if this flag is set after full
3581 -- processing of the corresponding declarative unit, it indicates that
3582 -- the variable or parameter was never set, and a warning message can
3585 -- Note: this flag is initially set, and then cleared on encountering
3586 -- any construct that might conceivably legitimately set the value.
3587 -- Thus during the analysis of a declarative region and its associated
3588 -- statement sequence, the meaning of the flag is "not set yet", and
3589 -- once this analysis is complete the flag means "never assigned".
3591 -- Note: for variables appearing in package declarations, this flag is
3592 -- never set. That is because there is no way to tell if some client
3593 -- modifies the variable (or, in the case of variables in the private
3594 -- part, if some child unit modifies the variables).
3596 -- Note: in the case of renamed objects, the flag must be set in the
3597 -- ultimate renamed object. Clients noting a possible modification
3598 -- should use the Note_Possible_Modification procedure in Sem_Util
3599 -- rather than Set_Never_Set_In_Source precisely to deal properly with
3600 -- the renaming possibility.
3602 -- Next_Component (synthesized)
3603 -- Applies to record components. Returns the next component by following
3604 -- the chain of declared entities until one is found which corresponds to
3605 -- a component (Ekind is E_Component). Any internal types generated from
3606 -- the subtype indications of the record components are skipped. Returns
3607 -- Empty if no more components.
3609 -- Next_Component_Or_Discriminant (synthesized)
3610 -- Similar to Next_Component, but includes components and discriminants
3611 -- so the input can have either E_Component or E_Discriminant, and the
3612 -- same is true for the result. Returns Empty if no more components or
3613 -- discriminants in the record.
3615 -- Next_Discriminant (synthesized)
3616 -- Applies to discriminants returned by First/Next_Discriminant. Returns
3617 -- the next language-defined (i.e. perhaps non-girder) discriminant by
3618 -- following the chain of declared entities as long as the kind of the
3619 -- entity corresponds to a discriminant. Note that the discriminants
3620 -- might be the only components of the record. Returns Empty if there
3621 -- are no more discriminants.
3623 -- Next_Entity (Node2)
3624 -- Defined in all entities. The entities of a scope are chained, with
3625 -- the head of the list being in the First_Entity field of the scope
3626 -- entity. All entities use the Next_Entity field as a forward pointer
3627 -- for this list, with Empty indicating the end of the list. Since this
3628 -- field is in the base part of the entity, the access routines for this
3629 -- field are in Sinfo.
3631 -- Next_Formal (synthesized)
3632 -- Applies to the entity for a formal parameter. Returns the next formal
3633 -- parameter of the subprogram or subprogram type. Returns Empty if there
3634 -- are no more formals.
3636 -- Next_Formal_With_Extras (synthesized)
3637 -- Applies to the entity for a formal parameter. Returns the next
3638 -- formal parameter of the subprogram or subprogram type. Returns
3639 -- Empty if there are no more formals. The list returned includes
3640 -- all the extra formals (see description of Extra_Formal field)
3642 -- Next_Index (synthesized)
3643 -- Applies to array types and subtypes and to string types and
3644 -- subtypes. Yields the next index. The first index is obtained by
3645 -- using the First_Index attribute, and then subsequent indexes are
3646 -- obtained by applying Next_Index to the previous index. Empty is
3647 -- returned to indicate that there are no more indexes. Note that
3648 -- unlike most attributes in this package, Next_Index applies to
3649 -- nodes for the indexes, not to entities.
3651 -- Next_Inlined_Subprogram (Node12)
3652 -- Defined in subprograms. Used to chain inlined subprograms used in
3653 -- the current compilation, in the order in which they must be compiled
3654 -- by the backend to ensure that all inlinings are performed.
3656 -- Next_Literal (synthesized)
3657 -- Applies to enumeration literals, returns the next literal, or
3658 -- Empty if applied to the last literal. This is actually a synonym
3659 -- for Next, but its use is preferred in this context.
3661 -- No_Dynamic_Predicate_On_Actual (Flag276)
3662 -- Defined in discrete types. Set for generic formal types that are used
3663 -- in loops and quantified expressions. The corresponing actual cannot
3664 -- have dynamic predicates.
3666 -- No_Pool_Assigned (Flag131) [root type only]
3667 -- Defined in access types. Set if a storage size clause applies to the
3668 -- variable with a static expression value of zero. This flag is used to
3669 -- generate errors if any attempt is made to allocate or free an instance
3670 -- of such an access type. This is set only in the root type, since
3671 -- derived types must have the same pool.
3673 -- No_Predicate_On_Actual (Flag275)
3674 -- Defined in discrete types. Set for generic formal types that are used
3675 -- in the spec of a generic package, in constructs that forbid discrete
3676 -- types with predicates.
3678 -- No_Reordering (Flag239) [implementation base type only]
3679 -- Defined in record types. Set only for a base type to which a valid
3680 -- pragma No_Component_Reordering applies.
3682 -- No_Return (Flag113)
3683 -- Defined in all entities. Always false except in the case of procedures
3684 -- and generic procedures for which a pragma No_Return is given.
3686 -- No_Strict_Aliasing (Flag136) [base type only]
3687 -- Defined in access types. Set to direct the backend to avoid any
3688 -- optimizations based on an assumption about the aliasing status of
3689 -- objects designated by the access type. For the case of the gcc
3690 -- backend, the effect is as though all references to objects of
3691 -- the type were compiled with -fno-strict-aliasing. This flag is
3692 -- set if an unchecked conversion with the access type as a target
3693 -- type occurs in the same source unit as the declaration of the
3694 -- access type, or if an explicit pragma No_Strict_Aliasing applies.
3696 -- No_Tagged_Streams_Pragma (Node32)
3697 -- Present in all subtype and type entities. Set for tagged types and
3698 -- subtypes (i.e. entities with Is_Tagged_Type set True) if a valid
3699 -- pragma/aspect applies to the type.
3701 -- Non_Binary_Modulus (Flag58) [base type only]
3702 -- Defined in all subtype and type entities. Set for modular integer
3703 -- types if the modulus value is other than a power of 2.
3705 -- Non_Limited_View (Node19)
3706 -- Defined in abstract states and incomplete types that act as shadow
3707 -- entities created when analysing a limited with clause (Ada 2005:
3708 -- AI-50217). Points to the defining entity of the original declaration.
3710 -- Nonzero_Is_True (Flag162) [base type only]
3711 -- Defined in enumeration types. Set if any non-zero value is to be
3712 -- interpreted as true. Currently this is set for derived Boolean
3713 -- types which have a convention of C, C++ or Fortran.
3715 -- Normalized_First_Bit (Uint8)
3716 -- Defined in components and discriminants. Indicates the normalized
3717 -- value of First_Bit for the component, i.e. the offset within the
3718 -- lowest addressed storage unit containing part or all of the field.
3719 -- Set to No_Uint if no first bit position is assigned yet.
3721 -- Normalized_Position (Uint14)
3722 -- Defined in components and discriminants. Indicates the normalized
3723 -- value of Position for the component, i.e. the offset in storage
3724 -- units from the start of the record to the lowest addressed storage
3725 -- unit containing part or all of the field.
3727 -- Normalized_Position_Max (Uint10)
3728 -- Defined in components and discriminants. For almost all cases, this
3729 -- is the same as Normalized_Position. The one exception is for the case
3730 -- of a discriminated record containing one or more arrays whose length
3731 -- depends on discriminants. In this case, the Normalized_Position_Max
3732 -- field represents the maximum possible value of Normalized_Position
3733 -- assuming min/max values for discriminant subscripts in all fields.
3734 -- This is used by Layout in front end layout mode to properly compute
3735 -- the maximum size of such records (needed for allocation purposes when
3736 -- there are default discriminants, and also for the 'Size value).
3738 -- Number_Dimensions (synthesized)
3739 -- Applies to array types and subtypes. Returns the number of dimensions
3740 -- of the array type or subtype as a value of type Pos.
3742 -- Number_Entries (synthesized)
3743 -- Applies to concurrent types. Returns the number of entries that are
3744 -- declared within the task or protected definition for the type.
3746 -- Number_Formals (synthesized)
3747 -- Applies to subprograms and subprogram types. Yields the number of
3748 -- formals as a value of type Pos.
3750 -- OK_To_Rename (Flag247)
3751 -- Defined only in entities for variables. If this flag is set, it
3752 -- means that if the entity is used as the initial value of an object
3753 -- declaration, the object declaration can be safely converted into a
3754 -- renaming to avoid an extra copy. This is set for variables which are
3755 -- generated by the expander to hold the result of evaluating some
3756 -- expression. Most notably, the local variables used to store the result
3757 -- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It
3758 -- is only worth setting this flag for composites, since for primitive
3759 -- types, it is cheaper to do the copy.
3761 -- Optimize_Alignment_Space (Flag241)
3762 -- Defined in type, subtype, variable, and constant entities. This
3763 -- flag records that the type or object is to be layed out in a manner
3764 -- consistent with Optimize_Alignment (Space) mode. The compiler and
3765 -- binder ensure a consistent view of any given type or object. If pragma
3766 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3767 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3769 -- Optimize_Alignment_Time (Flag242)
3770 -- Defined in type, subtype, variable, and constant entities. This
3771 -- flag records that the type or object is to be layed out in a manner
3772 -- consistent with Optimize_Alignment (Time) mode. The compiler and
3773 -- binder ensure a consistent view of any given type or object. If pragma
3774 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3775 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3777 -- Original_Access_Type (Node28)
3778 -- Defined in E_Access_Subprogram_Type entities. Set only if the access
3779 -- type was generated by the expander as part of processing an access-
3780 -- to-protected-subprogram type. Points to the access-to-protected-
3783 -- Original_Array_Type (Node21)
3784 -- Defined in modular types and array types and subtypes. Set only if
3785 -- the Is_Packed_Array_Impl_Type flag is set, indicating that the type
3786 -- is the implementation type for a packed array, and in this case it
3787 -- points to the original array type for which this is the packed
3788 -- array implementation type.
3790 -- Original_Protected_Subprogram (Node41)
3791 -- Defined in functions and procedures. Set only on internally built
3792 -- dispatching subprograms of protected types to reference their original
3793 -- non-dispatching protected subprogram since their names differ.
3795 -- Original_Record_Component (Node22)
3796 -- Defined in components, including discriminants. The usage depends
3797 -- on whether the record is a base type and whether it is tagged.
3799 -- In base tagged types:
3800 -- When the component is inherited in a record extension, it points
3801 -- to the original component (the entity of the ancestor component
3802 -- which is not itself inherited) otherwise it points to itself. The
3803 -- backend uses this attribute to implement the automatic dereference
3804 -- in the extension and to apply the transformation:
3806 -- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
3808 -- In base untagged types:
3809 -- Always points to itself except for non-girder discriminants, where
3810 -- it points to the girder discriminant it renames.
3812 -- In subtypes (tagged and untagged):
3813 -- Points to the component in the base type.
3815 -- Overlays_Constant (Flag243)
3816 -- Defined in all entities. Set only for E_Constant or E_Variable for
3817 -- which there is an address clause that causes the entity to overlay
3818 -- a constant object.
3820 -- Overridden_Operation (Node26)
3821 -- Defined in subprograms. For overriding operations, points to the
3822 -- user-defined parent subprogram that is being overridden. Note: this
3823 -- attribute uses the same field as Static_Initialization. The latter
3824 -- is only defined for internal initialization procedures, for which
3825 -- Overridden_Operation is irrelevant. Thus this attribute must not be
3826 -- set for init_procs.
3828 -- Package_Instantiation (Node26)
3829 -- Defined in packages and generic packages. When defined, this field
3830 -- references an N_Generic_Instantiation node associated with an
3831 -- instantiated package. In the case where the referenced node has
3832 -- been rewritten to an N_Package_Specification, the instantiation
3833 -- node is available from the Original_Node field of the package spec
3834 -- node. This is currently not guaranteed to be set in all cases, but
3835 -- when set, the field is used in Get_Package_Instantiation_Node as
3836 -- one of the means of obtaining the instantiation node. Eventually
3837 -- it should be set in all cases, including package entities associated
3838 -- with formal packages. ???
3840 -- Packed_Array_Impl_Type (Node23)
3841 -- Defined in array types and subtypes, except for the string literal
3842 -- subtype case, if the corresponding type is packed and implemented
3843 -- specially (either bit-packed or packed to eliminate holes in the
3844 -- non-contiguous enumeration index types). References the type used to
3845 -- represent the packed array, which is either a modular type for short
3846 -- static arrays or an array of System.Unsigned in the bit-packed case,
3847 -- or a regular array in the non-standard enumeration index case. Note
3848 -- that in some situations (internal types and references to fields of
3849 -- variant records), it is not always possible to construct this type in
3850 -- advance of its use. If this field is empty, then the necessary type
3851 -- is declared on the fly for each reference to the array.
3853 -- Parameter_Mode (synthesized)
3854 -- Applies to formal parameter entities. This is a synonym for Ekind,
3855 -- used when obtaining the formal kind of a formal parameter (the result
3856 -- is one of E_[In/Out/In_Out]_Parameter).
3858 -- Parent_Subtype (Node19) [base type only]
3859 -- Defined in E_Record_Type. Set only for derived tagged types, in which
3860 -- case it points to the subtype of the parent type. This is the type
3861 -- that is used as the Etype of the _parent field.
3863 -- Part_Of_Constituents (Elist10)
3864 -- Present in abstract state and variable entities. Contains all
3865 -- constituents that are subject to indicator Part_Of (both aspect and
3866 -- option variants).
3868 -- Part_Of_References (Elist11)
3869 -- Present in variable entities. Contains all references to the variable
3870 -- when it is subject to pragma Part_Of. If the variable is a constituent
3871 -- of a single protected/task type, the references are examined as they
3872 -- must appear only within the type defintion and the corresponding body.
3874 -- Partial_Invariant_Procedure (synthesized)
3875 -- Defined in types and subtypes. Set for private types when one or more
3876 -- [class-wide] type invariants apply to them. Points to the entity for a
3877 -- procedure which checks the invariant. This invariant procedure takes a
3878 -- single argument of the given type, and returns if the invariant holds,
3879 -- or raises exception Assertion_Error with an appropriate message if it
3880 -- does not hold. This attribute is defined but always Empty for private
3881 -- subtypes. This attribute is also set for the corresponding full type.
3883 -- Note: the reason this is marked as a synthesized attribute is that the
3884 -- way this is stored is as an element of the Subprograms_For_Type field.
3886 -- Partial_Refinement_Constituents (synthesized)
3887 -- Defined in abstract state entities. Returns the constituents that
3888 -- refine the state in the current scope, which are allowed in a global
3889 -- refinement in this scope. These consist of those constituents that are
3890 -- abstract states with no or only partial refinement visible, and those
3891 -- that are not themselves abstract states.
3893 -- Partial_View_Has_Unknown_Discr (Flag280)
3894 -- Present in all types. Set to Indicate that the partial view of a type
3895 -- has unknown discriminants. A default initialization of an object of
3896 -- the type does not require an invariant check (AI12-0133).
3898 -- Pending_Access_Types (Elist15)
3899 -- Defined in all types. Set for incomplete, private, Taft-amendment
3900 -- types, and their corresponding full views. This list contains all
3901 -- access types, both named and anonymous, declared between the partial
3902 -- and the full view. The list is used by the finalization machinery to
3903 -- ensure that the finalization masters of all pending access types are
3904 -- fully initialized when the full view is frozen.
3906 -- Postconditions_Proc (Node14)
3907 -- Defined in functions, procedures, entries, and entry families. Refers
3908 -- to the entity of the _Postconditions procedure used to check contract
3909 -- assertions on exit from a subprogram.
3911 -- Predicate_Function (synthesized)
3912 -- Defined in all types. Set for types for which (Has_Predicates is True)
3913 -- and for which a predicate procedure has been built that tests that the
3914 -- specified predicates are True. Contains the entity for the function
3915 -- which takes a single argument of the given type, and returns True if
3916 -- the predicate holds and False if it does not.
3918 -- Note: flag Has_Predicate does not imply that Predicate_Function is set
3919 -- to a non-empty entity; this happens, for example, for itypes created
3920 -- when instantiating generic units with private types with predicates.
3921 -- However, if an explicit pragma Predicate or Predicate aspect is given
3922 -- either for private or full type declaration then both Has_Predicates
3923 -- and a non-empty Predicate_Function will be set on both the partial and
3924 -- full views of the type.
3926 -- Note: the reason this is marked as a synthesized attribute is that the
3927 -- way this is stored is as an element of the Subprograms_For_Type field.
3929 -- Predicate_Function_M (synthesized)
3930 -- Defined in all types. Present only if Predicate_Function is present,
3931 -- and only if the predicate function has Raise_Expression nodes. It
3932 -- is the special version created for membership tests, where if one of
3933 -- these raise expressions is executed, the result is to return False.
3935 -- Predicated_Parent (Node38)
3936 -- Defined on itypes created by subtype indications, when the parent
3937 -- subtype has predicates. The itype shares the Predicate_Function
3938 -- of the predicated parent, but this function may not have been built
3939 -- at the point the Itype is constructed, so this attribute allows its
3940 -- retrieval at the point a predicate check needs to be generated.
3941 -- The utility Predicate_Function takes this link into account.
3943 -- Predicates_Ignored (Flag288)
3944 -- Defined on all types. Indicates whether the subtype declaration is in
3945 -- a context where Assertion_Policy is Ignore, in which case no checks
3946 -- (static or dynamic) must be generated for objects of the type.
3948 -- Prev_Entity (Node36)
3949 -- Defined in all entities. The entities of a scope are chained, and this
3950 -- field is used as a backward pointer for this entity list - effectivly
3951 -- making the entity chain doubly-linked.
3953 -- Primitive_Operations (synthesized)
3954 -- Defined in concurrent types, tagged record types and subtypes, tagged
3955 -- private types and tagged incomplete types. For concurrent types whose
3956 -- Corresponding_Record_Type (CRT) is available, returns the list of
3957 -- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist.
3958 -- For all the other types returns the Direct_Primitive_Operations.
3961 -- Defined in private components of protected types. Refers to the entity
3962 -- of the component renaming declaration generated inside protected
3963 -- subprograms, entries or barrier functions.
3965 -- Prival_Link (Node20)
3966 -- Defined in constants and variables which rename private components of
3967 -- protected types. Set to the original private component.
3969 -- Private_Dependents (Elist18)
3970 -- Defined in private (sub)types. Records the subtypes of the private
3971 -- type, derivations from it, and records and arrays with components
3972 -- dependent on the type.
3974 -- The subtypes are traversed when installing and deinstalling (the full
3975 -- view of) a private type in order to ensure correct view of the
3978 -- Used in similar fashion for incomplete types: holds list of subtypes
3979 -- of these incomplete types that have discriminant constraints. The
3980 -- full views of these subtypes are constructed when the full view of
3981 -- the incomplete type is processed.
3983 -- In addition, if the incomplete type is the designated type in an
3984 -- access definition for an access parameter, the operation may be
3985 -- a dispatching primitive operation, which is only known when the full
3986 -- declaration of the type is seen. Subprograms that have such an
3987 -- access parameter are also placed in the list of private_dependents.
3989 -- Private_View (Node22)
3990 -- For each private type, three entities are allocated, the private view,
3991 -- the full view, and the shadow entity. The shadow entity contains a
3992 -- copy of the private view and is used for restoring the proper private
3993 -- view after a region in which the full view is visible (and is copied
3994 -- into the entity normally used for the private view during this period
3995 -- of visibility). The Private_View field is self-referential when the
3996 -- private view lives in its normal entity, but in the copy that is made
3997 -- in the shadow entity, it points to the proper location in which to
3998 -- restore the private view saved in the shadow.
4000 -- Protected_Body_Subprogram (Node11)
4001 -- Defined in protected operations. References the entity for the
4002 -- subprogram which implements the body of the operation.
4004 -- Protected_Formal (Node22)
4005 -- Defined in formal parameters (in, in out and out parameters). Used
4006 -- only for formals of protected operations. References corresponding
4007 -- formal parameter in the unprotected version of the operation that
4008 -- is created during expansion.
4010 -- Protected_Subprogram (Node39)
4011 -- Defined in functions and procedures. Set for the pair of subprograms
4012 -- which emulate the runtime semantics of a protected subprogram. Denotes
4013 -- the entity of the origial protected subprogram.
4015 -- Protection_Object (Node23)
4016 -- Applies to protected entries, entry families and subprograms. Denotes
4017 -- the entity which is used to rename the _object component of protected
4020 -- Reachable (Flag49)
4021 -- Defined in labels. The flag is set over the range of statements in
4022 -- which a goto to that label is legal.
4024 -- Receiving_Entry (Node19)
4025 -- Defined in procedures. Set for an internally generated procedure which
4026 -- wraps the original statements of an accept alternative. Designates the
4027 -- entity of the task entry being accepted.
4029 -- Referenced (Flag156)
4030 -- Defined in all entities. Set if the entity is referenced, except for
4031 -- the case of an appearance of a simple variable that is not a renaming
4032 -- as the left side of an assignment in which case Referenced_As_LHS is
4033 -- set instead, or a similar appearance as an out parameter actual, in
4034 -- which case Referenced_As_Out_Parameter is set.
4036 -- Referenced_As_LHS (Flag36):
4037 -- Defined in all entities. This flag is set instead of Referenced if a
4038 -- simple variable that is not a renaming appears as the left side of an
4039 -- assignment. The reason we distinguish this kind of reference is that
4040 -- we have a separate warning for variables that are only assigned and
4043 -- Referenced_As_Out_Parameter (Flag227):
4044 -- Defined in all entities. This flag is set instead of Referenced if a
4045 -- simple variable that is not a renaming appears as an actual for an out
4046 -- formal. The reason we distinguish this kind of reference is that
4047 -- we have a separate warning for variables that are only assigned and
4048 -- never read, and out parameters are a special case.
4050 -- Refinement_Constituents (Elist8)
4051 -- Present in abstract state entities. Contains all the constituents that
4052 -- refine the state, in other words, all the hidden states that appear in
4053 -- the constituent_list of aspect/pragma Refined_State.
4055 -- Register_Exception_Call (Node20)
4056 -- Defined in exception entities. When an exception is declared,
4057 -- a call is expanded to Register_Exception. This field points to
4058 -- the expanded N_Procedure_Call_Statement node for this call. It
4059 -- is used for Import/Export_Exception processing to modify the
4060 -- register call to make appropriate entries in the special tables
4061 -- used for handling these pragmas at run time.
4063 -- Related_Array_Object (Node25)
4064 -- Defined in array types and subtypes. Used only for the base type
4065 -- and subtype created for an anonymous array object. Set to point
4066 -- to the entity of the corresponding array object. Currently used
4067 -- only for type-related error messages.
4069 -- Related_Expression (Node24)
4070 -- Defined in variables and types. When Set for internally generated
4071 -- entities, it may be used to denote the source expression whose
4072 -- elaboration created the variable declaration. If set, it is used
4073 -- for generating clearer messages from CodePeer. It is used on source
4074 -- entities that are variables in iterator specifications, to provide
4075 -- a link to the container that is the domain of iteration. This allows
4076 -- for better cross-reference information when the loop modifies elements
4077 -- of the container, and suppresses spurious warnings.
4079 -- Shouldn't it also be used for the same purpose in errout? It seems
4080 -- odd to have two mechanisms here???
4082 -- Related_Instance (Node15)
4083 -- Defined in the wrapper packages created for subprogram instances.
4084 -- The internal subprogram that implements the instance is inside the
4085 -- wrapper package, but for debugging purposes its external symbol
4086 -- must correspond to the name and scope of the related instance.
4088 -- Related_Type (Node27)
4089 -- Defined in components, constants and variables. Set when there is an
4090 -- associated dispatch table to point to entities containing primary or
4091 -- secondary tags. Not set in the _tag component of record types.
4093 -- Relative_Deadline_Variable (Node28) [implementation base type only]
4094 -- Defined in task type entities. This flag is set if a valid and
4095 -- effective pragma Relative_Deadline applies to the base type. Points
4096 -- to the entity for a variable that is created to hold the value given
4097 -- in a Relative_Deadline pragma for a task type.
4099 -- Renamed_Entity (Node18)
4100 -- Defined in exception, generic unit, package, and subprogram entities.
4101 -- Set when the entity is defined by a renaming declaration. Denotes the
4102 -- renamed entity, or transitively the ultimate renamed entity if there
4103 -- is a chain of renaming declarations. Empty if no renaming.
4105 -- Renamed_In_Spec (Flag231)
4106 -- Defined in package entities. If a package renaming occurs within
4107 -- a package spec, then this flag is set on the renamed package. The
4108 -- purpose is to prevent a warning about unused entities in the renamed
4109 -- package. Such a warning would be inappropriate since clients of the
4110 -- package can see the entities in the package via the renaming.
4112 -- Renamed_Object (Node18)
4113 -- Defined in components, constants, discriminants, formal parameters,
4114 -- generic formals, loop parameters, and variables. Set to non-Empty if
4115 -- the object was declared by a renaming declaration. For constants and
4116 -- variables, the attribute references the tree node for the name of the
4117 -- renamed object. For formal parameters, the field is used in inlining
4118 -- and maps the entities of all formal parameters of a subprogram to the
4119 -- entities of the corresponding actuals. For formals of a task entry,
4120 -- the attribute denotes the local renaming that replaces the actual
4121 -- within an accept statement. For all remaining cases (discriminants,
4122 -- loop parameters) the field is Empty.
4124 -- Renaming_Map (Uint9)
4125 -- Defined in generic subprograms, generic packages, and their
4126 -- instances. Also defined in the instances of the corresponding
4127 -- bodies. Denotes the renaming map (generic entities => instance
4128 -- entities) used to construct the instance by givin an index into
4129 -- the tables used to represent these maps. See Sem_Ch12 for further
4130 -- details. The maps for package instances are also used when the
4131 -- instance is the actual corresponding to a formal package.
4133 -- Requires_Overriding (Flag213)
4134 -- Defined in all subprograms and entries. Set for subprograms that
4135 -- require overriding as defined by RM-2005-3.9.3(6/2). Note that this
4136 -- is True only for implicitly declared subprograms; it is not set on the
4137 -- parent type's subprogram. See also Is_Abstract_Subprogram.
4139 -- Return_Applies_To (Node8)
4140 -- Defined in E_Return_Statement. Points to the entity representing
4141 -- the construct to which the return statement applies, as defined in
4142 -- RM-6.5(4/2). Note that a (simple) return statement within an
4143 -- extended_return_statement applies to the extended_return_statement,
4144 -- even though it causes the whole function to return.
4146 -- Return_Present (Flag54)
4147 -- Defined in function and generic function entities. Set if the
4148 -- function contains a return statement (used for error checking).
4149 -- This flag can also be set in procedure and generic procedure
4150 -- entities (for convenience in setting it), but is only tested
4151 -- for the function case.
4153 -- Returns_By_Ref (Flag90)
4154 -- Defined in function entities. Set if the function returns the result
4155 -- by reference, either because its return type is a by-reference-type
4156 -- or because the function explicitly uses the secondary stack.
4158 -- Reverse_Bit_Order (Flag164) [base type only]
4159 -- Defined in all record type entities. Set if entity has a Bit_Order
4160 -- aspect (set by an aspect clause or attribute definition clause) that
4161 -- has reversed the order of bits from the default value. When this flag
4162 -- is set, a component clause must specify a set of bits entirely within
4163 -- a single storage unit (Ada 95) or within a single machine scalar (see
4164 -- Ada 2005 AI-133), or must occupy an integral number of storage units.
4166 -- Reverse_Storage_Order (Flag93) [base type only]
4167 -- Defined in all record and array type entities. Set if entity has a
4168 -- Scalar_Storage_Order aspect (set by an aspect clause or attribute
4169 -- definition clause) that has reversed the order of storage elements
4170 -- from the default value. When this flag is set for a record type,
4171 -- the Bit_Order aspect must be set to the same value (either explicitly
4172 -- or as the target default value).
4174 -- Rewritten_For_C (Flag287)
4175 -- Defined on functions that return a constrained array type, when
4176 -- Modify_Tree_For_C is set. Indicates that a procedure with an extra
4177 -- out parameter has been created for it, and calls must be rewritten as
4178 -- calls to the new procedure.
4181 -- Defined in all type and subtype entities. Contains the value of
4182 -- type'Size as defined in the RM. See also the Esize field and
4183 -- and the description on "Handling of Type'Size Values". A value
4184 -- of zero in this field for a non-discrete type means that
4185 -- the front end has not yet determined the size value. For the
4186 -- case of a discrete type, this field is always set by the front
4187 -- end and zero is a legitimate value for a type with one value.
4189 -- Root_Type (synthesized)
4190 -- Applies to all type entities. For class-wide types, returns the root
4191 -- type of the class covered by the CW type, otherwise returns the
4192 -- ultimate derivation ancestor of the given type. This function
4193 -- preserves the view, i.e. the Root_Type of a partial view is the
4194 -- partial view of the ultimate ancestor, the Root_Type of a full view
4195 -- is the full view of the ultimate ancestor. Note that this function
4196 -- does not correspond exactly to the use of root type in the RM, since
4197 -- in the RM root type applies to a class of types, not to a type.
4199 -- Scalar_Range (Node20)
4200 -- Defined in all scalar types (including modular types, where the
4201 -- bounds are 0 .. modulus - 1). References a node in the tree that
4202 -- contains the bounds for the range. Note that this information
4203 -- could be obtained by rummaging around the tree, but it is more
4204 -- convenient to have it immediately at hand in the entity. The
4205 -- contents of Scalar_Range can either be an N_Subtype_Indication
4206 -- node (with a constraint), or a Range node, but not a simple
4207 -- subtype reference (a subtype is converted into a range).
4209 -- Scale_Value (Uint16)
4210 -- Defined in decimal fixed-point types and subtypes. Contains the scale
4211 -- for the type (i.e. the value of type'Scale = the number of decimal
4212 -- digits after the decimal point).
4215 -- Defined in all entities. Points to the entity for the scope (block,
4216 -- loop, subprogram, package etc.) in which the entity is declared.
4217 -- Since this field is in the base part of the entity node, the access
4218 -- routines for this field are in Sinfo. Note that for a child unit,
4219 -- the Scope will be the parent package, and for a root library unit,
4220 -- the Scope will be Standard.
4222 -- Scope_Depth (synthesized)
4223 -- Applies to program units, blocks, concurrent types and entries, and
4224 -- also to record types, i.e. to any entity that can appear on the scope
4225 -- stack. Yields the scope depth value, which for those entities other
4226 -- than records is simply the scope depth value, for record entities, it
4227 -- is the Scope_Depth of the record scope.
4229 -- Scope_Depth_Value (Uint22)
4230 -- Defined in program units, blocks, concurrent types, and entries.
4231 -- Indicates the number of scopes that statically enclose the declaration
4232 -- of the unit or type. Library units have a depth of zero. Note that
4233 -- record types can act as scopes but do NOT have this field set (see
4234 -- Scope_Depth above).
4236 -- Scope_Depth_Set (synthesized)
4237 -- Applies to a special predicate function that returns a Boolean value
4238 -- indicating whether or not the Scope_Depth field has been set. It is
4239 -- needed, since returns an invalid value in this case.
4241 -- Sec_Stack_Needed_For_Return (Flag167)
4242 -- Defined in scope entities (blocks, entries, entry families, functions,
4243 -- and procedures). Set to True when secondary stack is used to hold the
4244 -- returned value of a function and thus should not be released on scope
4247 -- Shadow_Entities (List14)
4248 -- Defined in package and generic package entities. Points to a list
4249 -- of entities that correspond to private types. For each private type
4250 -- a shadow entity is created that holds a copy of the private view.
4251 -- In regions of the program where the full views of these private
4252 -- entities are visible, the full view is copied into the entity that
4253 -- is normally used to hold the private view, but the shadow entity
4254 -- copy is unchanged. The shadow entities are then used to restore the
4255 -- original private views at the end of the region. This list is a
4256 -- standard format list (i.e. First (Shadow_Entities) is the first
4257 -- entry and subsequent entries are obtained using Next.
4259 -- Shared_Var_Procs_Instance (Node22)
4260 -- Defined in variables. Set non-Empty only if Is_Shared_Passive is
4261 -- set, in which case this is the entity for the associated instance of
4262 -- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details.
4264 -- Size_Check_Code (Node19)
4265 -- Defined in constants and variables. Normally Empty. Set if code is
4266 -- generated to check the size of the object. This field is used to
4267 -- suppress this code if a subsequent address clause is encountered.
4269 -- Size_Clause (synthesized)
4270 -- Applies to all entities. If a size clause is present in the rep
4271 -- item chain for an entity then the attribute definition clause node
4272 -- for the size clause is returned. Otherwise Size_Clause returns Empty
4273 -- if no item is present. Usually this is only meaningful if the flag
4274 -- Has_Size_Clause is set. This is because when the representation item
4275 -- chain is copied for a derived type, it can inherit a size clause that
4276 -- is not applicable to the entity.
4278 -- Size_Depends_On_Discriminant (Flag177)
4279 -- Defined in all entities for types and subtypes. Indicates that the
4280 -- size of the type depends on the value of one or more discriminants.
4281 -- Currently, this flag is only set for arrays which have one or more
4282 -- bounds depending on a discriminant value.
4284 -- Size_Known_At_Compile_Time (Flag92)
4285 -- Defined in all entities for types and subtypes. Indicates that the
4286 -- size of objects of the type is known at compile time. This flag is
4287 -- used to optimize some generated code sequences, and also to enable
4288 -- some error checks (e.g. disallowing component clauses on variable
4289 -- length objects). It is set conservatively (i.e. if it is True, the
4290 -- size is certainly known at compile time, if it is False, then the
4291 -- size may or may not be known at compile time, but the code will
4292 -- assume that it is not known). Note that the value may be known only
4293 -- to the back end, so the fact that this flag is set does not mean that
4294 -- the front end can access the value.
4296 -- Small_Value (Ureal21)
4297 -- Defined in fixed point types. Points to the universal real for the
4298 -- Small of the type, either as given in a representation clause, or
4299 -- as computed (as a power of two) by the compiler.
4301 -- SPARK_Aux_Pragma (Node41)
4302 -- Present in concurrent type, [generic] package spec and package body
4303 -- entities. For concurrent types and package specs it refers to the
4304 -- SPARK mode setting for the private part. This field points to the
4305 -- N_Pragma node that either appears in the private part or is inherited
4306 -- from the enclosing context. For package bodies, it refers to the SPARK
4307 -- mode of the elaboration sequence after the BEGIN. The fields points to
4308 -- the N_Pragma node that either appears in the statement sequence or is
4309 -- inherited from the enclosing context. In all cases, if the pragma is
4310 -- inherited, then the SPARK_Aux_Pragma_Inherited flag is set.
4312 -- SPARK_Aux_Pragma_Inherited (Flag266)
4313 -- Present in concurrent type, [generic] package spec and package body
4314 -- entities. Set if the SPARK_Aux_Pragma field points to a pragma that is
4315 -- inherited, rather than a local one.
4317 -- SPARK_Pragma (Node40)
4318 -- Present in the following entities:
4324 -- [generic] packages
4326 -- [generic] subprograms
4327 -- subprogram bodies
4331 -- Points to the N_Pragma node that applies to the initial declaration or
4332 -- body. This is either set by a local SPARK_Mode pragma or is inherited
4333 -- from the context (from an outer scope for the spec case or from the
4334 -- spec for the body case). In the case where the attribute is inherited,
4335 -- flag SPARK_Pragma_Inherited is set. Empty if no SPARK_Mode pragma is
4338 -- SPARK_Pragma_Inherited (Flag265)
4339 -- Present in the following entities:
4345 -- [generic] packages
4347 -- [generic] subprograms
4348 -- subprogram bodies
4352 -- Set if the SPARK_Pragma attribute points to an inherited pragma rather
4353 -- than a local one.
4355 -- Spec_Entity (Node19)
4356 -- Defined in package body entities. Points to corresponding package
4357 -- spec entity. Also defined in subprogram body parameters in the
4358 -- case where there is a separate spec, where this field references
4359 -- the corresponding parameter entities in the spec.
4361 -- SSO_Set_High_By_Default (Flag273) [base type only]
4362 -- Defined for record and array types. Set in the base type if a pragma
4363 -- Default_Scalar_Storage_Order (High_Order_First) was active at the time
4364 -- the record or array was declared and therefore applies to it.
4366 -- SSO_Set_Low_By_Default (Flag272) [base type only]
4367 -- Defined for record and array types. Set in the base type if a pragma
4368 -- Default_Scalar_Storage_Order (High_Order_First) was active at the time
4369 -- the record or array was declared and therefore applies to it.
4371 -- Static_Discrete_Predicate (List25)
4372 -- Defined in discrete types/subtypes with static predicates (with the
4373 -- two flags Has_Predicates and Has_Static_Predicate set). Set if the
4374 -- type/subtype has a static predicate. Points to a list of expression
4375 -- and N_Range nodes that represent the predicate in canonical form. The
4376 -- canonical form has entries sorted in ascending order, with duplicates
4377 -- eliminated, and adjacent ranges coalesced, so that there is always a
4378 -- gap in the values between successive entries. The entries in this list
4379 -- are fully analyzed and typed with the base type of the subtype. Note
4380 -- that all entries are static and have values within the subtype range.
4382 -- Static_Elaboration_Desired (Flag77)
4383 -- Defined in library-level packages. Set by the pragma of the same
4384 -- name, to indicate that static initialization must be attempted for
4385 -- all types declared in the package, and that a warning must be emitted
4386 -- for those types to which static initialization is not available.
4388 -- Static_Initialization (Node30)
4389 -- Defined in initialization procedures for types whose objects can be
4390 -- initialized statically. The value of this attribute is a positional
4391 -- aggregate whose components are compile-time static values. Used
4392 -- when available in object declarations to eliminate the call to the
4393 -- initialization procedure, and to minimize elaboration code. Note:
4394 -- This attribute uses the same field as Overridden_Operation, which is
4395 -- irrelevant in init_procs.
4397 -- Static_Real_Or_String_Predicate (Node25)
4398 -- Defined in real types/subtypes with static predicates (with the two
4399 -- flags Has_Predicates and Has_Static_Predicate set). Set if the type
4400 -- or subtype has a static predicate. Points to the return expression
4401 -- of the predicate function. This is the original expression given as
4402 -- the predicate except that occurrences of the type are replaced by
4403 -- occurrences of the formal parameter of the predicate function (note
4404 -- that the spec of this function including this formal parameter name
4405 -- is available from the Subprograms_For_Type field; it can be accessed
4406 -- as Predicate_Function (typ)). Also, in the case where a predicate is
4407 -- inherited, the expression is of the form:
4409 -- xxxPredicate (typ2 (ent)) AND THEN expression
4411 -- where typ2 is the type from which the predicate is inherited, ent is
4412 -- the entity for the current predicate function, and xxxPredicate is the
4413 -- inherited predicate (from typ2). Finally for a predicate that inherits
4414 -- from another predicate but does not add a predicate of its own, the
4415 -- expression may consist of the above xxxPredicate call on its own.
4417 -- Status_Flag_Or_Transient_Decl (Node15)
4418 -- Defined in constant, loop, and variable entities. Applies to objects
4419 -- that require special treatment by the finalization machinery, such as
4420 -- extended return results, IF and CASE expression results, and objects
4421 -- inside N_Expression_With_Actions nodes. The attribute contains the
4422 -- entity of a flag which specifies particular behavior over a region of
4423 -- code or the declaration of a "hook" object.
4424 -- In which case is it a flag, or a hook object???
4426 -- Storage_Size_Variable (Node26) [implementation base type only]
4427 -- Defined in access types and task type entities. This flag is set
4428 -- if a valid and effective pragma Storage_Size applies to the base
4429 -- type. Points to the entity for a variable that is created to
4430 -- hold the value given in a Storage_Size pragma for an access
4431 -- collection or a task type. Note that in the access type case,
4432 -- this field is defined only in the root type (since derived types
4433 -- share the same storage pool).
4435 -- Stored_Constraint (Elist23)
4436 -- Defined in entities that can have discriminants (concurrent types
4437 -- subtypes, record types and subtypes, private types and subtypes,
4438 -- limited private types and subtypes and incomplete types). Points
4439 -- to an element list containing the expressions for each of the
4440 -- stored discriminants for the record (sub)type.
4442 -- Stores_Attribute_Old_Prefix (Flag270)
4443 -- Defined in constants. Set when the constant has been generated to save
4444 -- the value of attribute 'Old's prefix.
4446 -- Strict_Alignment (Flag145) [implementation base type only]
4447 -- Defined in all type entities. Indicates that some containing part
4448 -- is either aliased or tagged. This prohibits packing the object
4449 -- tighter than its natural size and alignment.
4451 -- String_Literal_Length (Uint16)
4452 -- Defined in string literal subtypes (which are created to correspond
4453 -- to string literals in the program). Contains the length of the string
4456 -- String_Literal_Low_Bound (Node18)
4457 -- Defined in string literal subtypes (which are created to correspond
4458 -- to string literals in the program). Contains an expression whose
4459 -- value represents the low bound of the literal. This is a copy of
4460 -- the low bound of the applicable index constraint if there is one,
4461 -- or a copy of the low bound of the index base type if not.
4463 -- Subprograms_For_Type (Elist29)
4464 -- Defined in all types. The list may contain the entities of the default
4465 -- initial condition procedure, invariant procedure, and the two versions
4466 -- of the predicate function.
4468 -- Historical note: This attribute used to be a direct linked list of
4469 -- entities rather than an Elist. The Elist allows greater flexibility
4470 -- in inheritance of subprograms between views of the same type.
4472 -- Subps_Index (Uint24)
4473 -- Present in subprogram entries. Set if the subprogram contains nested
4474 -- subprograms, or is a subprogram nested within such a subprogram. Holds
4475 -- the index in the Exp_Unst.Subps table for the subprogram. Note that
4476 -- for the outer level subprogram, this is the starting index in the Subp
4477 -- table for the entries for this subprogram.
4479 -- Suppress_Elaboration_Warnings (Flag303)
4480 -- NOTE: this flag is relevant only for the legacy ABE mechanism and
4481 -- should not be used outside of that context.
4483 -- Defined in all entities, can be set only for subprogram entities and
4484 -- for variables. If this flag is set then Sem_Elab will not generate
4485 -- elaboration warnings for the subprogram or variable. Suppression of
4486 -- such warnings is automatic for subprograms for which elaboration
4487 -- checks are suppressed (without the need to set this flag), but the
4488 -- flag is also set for various internal entities (such as init procs)
4489 -- which are known not to generate any possible access before elaboration
4490 -- and it is set on variables when a warning is given to avoid multiple
4491 -- elaboration warnings for the same variable.
4493 -- Suppress_Initialization (Flag105)
4494 -- Defined in all variable, type and subtype entities. If set for a base
4495 -- type, then the generation of initialization procedures is suppressed
4496 -- for the type. Any other implicit initialiation (e.g. from the use of
4497 -- pragma Initialize_Scalars) is also suppressed if this flag is set for
4498 -- either the subtype in question, or for the base type. For variables,
4499 -- this flag suppresses all implicit initialization for the object, even
4500 -- if the type would normally require initialization. Set by use of
4501 -- pragma Suppress_Initialization and also for internal entities where
4502 -- we know that no initialization is required. For example, enumeration
4503 -- image table entities set it.
4505 -- Suppress_Style_Checks (Flag165)
4506 -- Defined in all entities. Suppresses any style checks specifically
4507 -- associated with the given entity if set.
4509 -- Suppress_Value_Tracking_On_Call (Flag217)
4510 -- Defined in all entities. Set in a scope entity if value tracking is to
4511 -- be suppressed on any call within the scope. Used when an access to a
4512 -- local subprogram is computed, to deal with the possibility that this
4513 -- value may be passed around, and if used, may clobber a local variable.
4515 -- Task_Body_Procedure (Node25)
4516 -- Defined in task types and subtypes. Points to the entity for the task
4517 -- task body procedure (as further described in Exp_Ch9, task bodies are
4518 -- expanded into procedures). A convenient function to retrieve this
4519 -- field is Sem_Util.Get_Task_Body_Procedure.
4521 -- The last sentence is odd??? Why not have Task_Body_Procedure go to the
4522 -- Underlying_Type of the Root_Type???
4524 -- Thunk_Entity (Node31)
4525 -- Defined in functions and procedures which have been classified as
4526 -- Is_Thunk. Set to the target entity called by the thunk.
4528 -- Treat_As_Volatile (Flag41)
4529 -- Defined in all type entities, and also in constants, components and
4530 -- variables. Set if this entity is to be treated as volatile for code
4531 -- generation purposes. Always set if Is_Volatile is set, but can also
4532 -- be set as a result of situations (such as address overlays) where
4533 -- the front end wishes to force volatile handling to inhibit aliasing
4534 -- optimization which might be legally ok, but is undesirable. Note
4535 -- that the backend always tests this flag rather than Is_Volatile.
4536 -- The front end tests Is_Volatile if it is concerned with legality
4537 -- checks associated with declared volatile variables, but if the test
4538 -- is for the purposes of suppressing optimizations, then the front
4539 -- end should test Treat_As_Volatile rather than Is_Volatile.
4541 -- Note: before testing Treat_As_Volatile, consider whether it would
4542 -- be more appropriate to use Exp_Util.Is_Volatile_Reference instead,
4543 -- which catches more cases of volatile references.
4545 -- Type_High_Bound (synthesized)
4546 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
4547 -- the high bound of a scalar type. The returned value is literal for a
4548 -- base type, but may be an expression in the case of scalar type with
4549 -- dynamic bounds. Note that in the case of a fixed point type, the high
4550 -- bound is in units of small, and is an integer.
4552 -- Type_Low_Bound (synthesized)
4553 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
4554 -- the low bound of a scalar type. The returned value is literal for a
4555 -- base type, but may be an expression in the case of scalar type with
4556 -- dynamic bounds. Note that in the case of a fixed point type, the low
4557 -- bound is in units of small, and is an integer.
4559 -- Underlying_Full_View (Node19)
4560 -- Defined in private subtypes that are the completion of other private
4561 -- types, or in private types that are derived from private subtypes. If
4562 -- the full view of a private type T is derived from another private type
4563 -- with discriminants Td, the full view of T is also private, and there
4564 -- is no way to attach to it a further full view that would convey the
4565 -- structure of T to the backend. The Underlying_Full_View is an
4566 -- attribute of the full view that is a subtype of Td with the same
4567 -- constraint as the declaration for T. The declaration for this subtype
4568 -- is built at the point of the declaration of T, either as completion,
4569 -- or as a subtype declaration where the base type is private and has a
4570 -- private completion. If Td is already constrained, then its full view
4571 -- can serve directly as the full view of T.
4573 -- Underlying_Record_View (Node28)
4574 -- Defined in record types. Set for record types that are extensions of
4575 -- types with unknown discriminants, and also set for internally built
4576 -- underlying record views to reference its original record type. Record
4577 -- types that are extensions of types with unknown discriminants do not
4578 -- have a completion, but they cannot be used without having some
4579 -- discriminated view at hand. This view is a record type with the same
4580 -- structure, whose parent type is the full view of the parent in the
4581 -- original type extension.
4583 -- Underlying_Type (synthesized)
4584 -- Applies to all entities. This is the identity function except in the
4585 -- case where it is applied to an incomplete or private type, in which
4586 -- case it is the underlying type of the type declared by the completion,
4587 -- or Empty if the completion has not yet been encountered and analyzed.
4589 -- Note: the reason this attribute applies to all entities, and not just
4590 -- types, is to legitimize code where Underlying_Type is applied to an
4591 -- entity which may or may not be a type, with the intent that if it is a
4592 -- type, its underlying type is taken.
4594 -- Note also that the value of this attribute is interesting only after
4595 -- the full view of the parent type has been processed. If the parent
4596 -- type is declared in an enclosing package, the attribute will be non-
4597 -- trivial only after the full view of the type has been analyzed.
4599 -- Universal_Aliasing (Flag216) [implementation base type only]
4600 -- Defined in all type entities. Set to direct the back-end to avoid
4601 -- any optimizations based on type-based alias analysis for this type.
4602 -- Indicates that objects of this type can alias objects of any other
4603 -- types, which guarantees that any objects can be referenced through
4604 -- access types designating this type safely, whatever the actual type
4605 -- of these objects. In other words, the effect is as though access
4606 -- types designating this type were subject to No_Strict_Aliasing.
4608 -- Unset_Reference (Node16)
4609 -- Defined in variables and out parameters. This is normally Empty. It
4610 -- is set to point to an identifier that represents a reference to the
4611 -- entity before any value has been set. Only the first such reference
4612 -- is identified. This field is used to generate a warning message if
4613 -- necessary (see Sem_Warn.Check_Unset_Reference).
4615 -- Used_As_Generic_Actual (Flag222)
4616 -- Defined in all entities, set if the entity is used as an argument to
4617 -- a generic instantiation. Used to tune certain warning messages, and
4618 -- in checking type conformance within an instantiation that involves
4619 -- incomplete formal and actual types.
4621 -- Uses_Lock_Free (Flag188)
4622 -- Defined in protected type entities. Set to True when the Lock Free
4623 -- implementation is used for the protected type. This implementation is
4624 -- based on atomic transactions and doesn't require anymore the use of
4625 -- Protection object (see System.Tasking.Protected_Objects).
4627 -- Uses_Sec_Stack (Flag95)
4628 -- Defined in scope entities (blocks, entries, entry families, functions,
4629 -- loops, and procedures). Set to True when the secondary stack is used
4630 -- in this scope and must be released on exit unless flag
4631 -- Sec_Stack_Needed_For_Return is set.
4633 -- Validated_Object (Node38)
4634 -- Defined in variables. Contains the object whose value is captured by
4635 -- the variable for validity check purposes.
4637 -- Warnings_Off (Flag96)
4638 -- Defined in all entities. Set if a pragma Warnings (Off, entity-name)
4639 -- is used to suppress warnings for a given entity. It is also used by
4640 -- the compiler in some situations to kill spurious warnings. Note that
4641 -- clients should generally not test this flag directly, but instead
4642 -- use function Has_Warnings_Off.
4644 -- Warnings_Off_Used (Flag236)
4645 -- Defined in all entities. Can only be set if Warnings_Off is set. If
4646 -- set indicates that a warning was suppressed by the Warnings_Off flag,
4647 -- and Unmodified/Unreferenced would not have suppressed the warning.
4649 -- Warnings_Off_Used_Unmodified (Flag237)
4650 -- Defined in all entities. Can only be set if Warnings_Off is set and
4651 -- Has_Pragma_Unmodified is not set. If set indicates that a warning was
4652 -- suppressed by the Warnings_Off status but that pragma Unmodified
4653 -- would also have suppressed the warning.
4655 -- Warnings_Off_Used_Unreferenced (Flag238)
4656 -- Defined in all entities. Can only be set if Warnings_Off is set and
4657 -- Has_Pragma_Unreferenced is not set. If set indicates that a warning
4658 -- was suppressed by the Warnings_Off status but that pragma Unreferenced
4659 -- would also have suppressed the warning.
4661 -- Was_Hidden (Flag196)
4662 -- Defined in all entities. Used to save the value of the Is_Hidden
4663 -- attribute when the limited-view is installed (Ada 2005: AI-217).
4665 -- Wrapped_Entity (Node27)
4666 -- Defined in functions and procedures which have been classified as
4667 -- Is_Primitive_Wrapper. Set to the entity being wrapper.
4669 ---------------------------
4670 -- Renaming and Aliasing --
4671 ---------------------------
4673 -- Several entity attributes relate to renaming constructs, and to the use of
4674 -- different names to refer to the same entity. The following is a summary of
4675 -- these constructs and their prefered uses.
4677 -- There are three related attributes:
4683 -- They all overlap because they are supposed to apply to different entity
4684 -- kinds. They are semantically related, and have the following intended uses:
4686 -- a) Renamed_Entity appplies to entities in renaming declarations that rename
4687 -- an entity, so the value of the attribute IS an entity. This applies to
4688 -- generic renamings, package renamings, exception renamings, and subprograms
4689 -- renamings that rename a subprogram (rather than an attribute, an entry, a
4690 -- protected operation, etc).
4692 -- b) Alias applies to overloadable entities, and the value is an overloadable
4693 -- entity. So this is a subset of the previous one. We use the term Alias to
4694 -- cover both renamings and inherited operations, because both cases are
4695 -- handled in the same way when expanding a call. Namely the Alias of a given
4696 -- subprogram is the subprogram that will actually be called.
4698 -- Both a) and b) are set transitively, so that in fact it is not necessary to
4699 -- traverse chains of renamings when looking for the original entity: it's
4700 -- there in one step (this is done when analyzing renaming declarations other
4701 -- than object renamings in sem_ch8).
4703 -- c) Renamed_Object applies to constants and variables. Given that the name
4704 -- in an object renaming declaration is not necessarily an entity name, the
4705 -- value of the attribute is the tree for that name, eg AR (1).Comp. The case
4706 -- when that name is in fact an entity is not handled specially. This is why
4707 -- in a few cases we need to use a loop to trace a chain of object renamings
4708 -- where all of them happen to be entities. So:
4711 -- Y : integer renames X; -- renamed object is the identifier X
4712 -- Z : integer renames Y; -- renamed object is the identifier Y
4714 -- The front-end does not store explicitly the fact that Z renames X.
4716 --------------------------------------
4717 -- Delayed Freezing and Elaboration --
4718 --------------------------------------
4720 -- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
4721 -- freeze node, which appears later in the expanded tree.
4723 -- a) The flag is used by the front-end to trigger expansion actions
4724 -- which include the generation of that freeze node. Typically this happens at
4725 -- the end of the current compilation unit, or before the first subprogram
4726 -- body is encountered in the current unit. See files freeze and exp_ch13 for
4727 -- details on the actions triggered by a freeze node, which include the
4728 -- construction of initialization procedures and dispatch tables.
4730 -- b) The flag is used by the backend to defer elaboration of the entity until
4731 -- its freeze node is seen. In the absence of an explicit freeze node, an
4732 -- entity is frozen (and elaborated) at the point of declaration.
4734 -- For object declarations, the flag is set when an address clause for the
4735 -- object is encountered. Legality checks on the address expression only
4736 -- take place at the freeze point of the object.
4738 -- Most types have an explicit freeze node, because they cannot be elaborated
4739 -- until all representation and operational items that apply to them have been
4740 -- analyzed. Private types and incomplete types have the flag set as well, as
4741 -- do task and protected types.
4743 -- Implicit base types created for type derivations, as well as classwide
4744 -- types created for all tagged types, have the flag set.
4746 -- If a subprogram has an access parameter whose designated type is incomplete
4747 -- the subprogram has the flag set.
4753 -- The following entity kinds are introduced by the corresponding type
4757 -- E_General_Access_Type,
4758 -- E_Access_Subprogram_Type,
4759 -- E_Anonymous_Access_Subprogram_Type,
4760 -- E_Access_Protected_Subprogram_Type,
4761 -- E_Anonymous_Access_Protected_Subprogram_Type
4762 -- E_Anonymous_Access_Type.
4764 -- E_Access_Subtype is for an access subtype created by a subtype
4767 -- In addition, we define the kind E_Allocator_Type to label allocators.
4768 -- This is because special resolution rules apply to this construct.
4769 -- Eventually the constructs are labeled with the access type imposed by
4770 -- the context. The backend should never see types with this Ekind.
4772 -- Similarly, the type E_Access_Attribute_Type is used as the initial kind
4773 -- associated with an access attribute. After resolution a specific access
4774 -- type will be established as determined by the context.
4776 -- Finally, the type Any_Access is used to label -null- during type
4777 -- resolution. Any_Access is also replaced by the context type after
4780 --------------------------------
4781 -- Classification of Entities --
4782 --------------------------------
4784 -- The classification of program entities which follows is a refinement of
4785 -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
4786 -- different type classes. Ada 95 entities include class wide types,
4787 -- protected types, subprogram types, generalized access types, generic
4788 -- formal derived types and generic formal packages.
4790 -- The order chosen for these kinds allows us to classify related entities
4791 -- so that they are contiguous. As a result, they do not appear in the
4792 -- exact same order as their order of first appearance in the LRM (For
4793 -- example, private types are listed before packages). The contiguity
4794 -- allows us to define useful subtypes (see below) such as type entities,
4795 -- overloaded entities, etc.
4797 -- Each entity (explicitly or implicitly declared) has a kind, which is
4798 -- a value of the following type:
4800 type Entity_Kind
is (
4803 -- The initial Ekind value for a newly created entity. Also used as the
4804 -- Ekind for Standard_Void_Type, a type entity in Standard used as a
4805 -- dummy type for the return type of a procedure (the reason we create
4806 -- this type is to share the circuits for performing overload resolution
4814 -- Components of a record declaration, private declarations of
4815 -- protected objects.

5041 E_Limited_Private_Subtype
,
5042 -- A subtype of a limited private type, created by a subtype declaration
5043 -- used to declare a subtype of a limited private type.
5046 -- An incomplete type, created by an incomplete type declaration
5048 E_Incomplete_Subtype
,
5049 -- An incomplete subtype, created by a subtype declaration where the
5050 -- subtype mark denotes an incomplete type.
5053 -- A task type, created by a task type declaration. An entity with this
5054 -- Ekind is also created to describe the anonymous type of a task that
5055 -- is created by a single task declaration.
5058 -- A subtype of a task type, created by a subtype declaration used to
5059 -- declare a subtype of a task type.
5062 -- A protected type, created by a protected type declaration. An entity
5063 -- with this Ekind is also created to describe the anonymous type of
5064 -- a protected object created by a single protected declaration.
5066 E_Protected_Subtype
,
5067 -- A subtype of a protected type, created by a subtype declaration used
5068 -- to declare a subtype of a protected type.
5075 -- The type of an exception created by an exception declaration
5078 -- This is the designated type of an Access_To_Subprogram. Has type and
5079 -- signature like a subprogram entity, so can appear in calls, which

5087 E_Enumeration_Literal
,
5088 -- An enumeration literal, created by the use of the literal in an
5089 -- enumeration type definition.
5092 -- A function, created by a function declaration or a function body
5093 -- that acts as its own declaration.
5096 -- A predefined operator, appearing in Standard, or an implicitly
5097 -- defined concatenation operator created whenever an array is declared.
5098 -- We do not make normal derived operators explicit in the tree, but the
5099 -- concatenation operators are made explicit.
5102 -- A procedure, created by a procedure declaration or a procedure
5103 -- body that acts as its own declaration.
5106 -- A state abstraction. Used to designate entities introduced by aspect
5107 -- or pragma Abstract_State. The entity carries the various properties
5111 -- An entry, created by an entry declaration in a task or protected
5114 --------------------
5115 -- Other Entities --
5116 --------------------
5119 -- An entry family, created by an entry family declaration in a
5120 -- task or protected type definition.
5123 -- A block identifier, created by an explicit or implicit label on
5124 -- a block or declare statement.
5126 E_Entry_Index_Parameter
,
5127 -- An entry index parameter created by an entry index specification
5128 -- for the body of a protected entry family.
5131 -- An exception created by an exception declaration. The exception
5132 -- itself uses E_Exception for the Ekind, the implicit type that is
5133 -- created to represent its type uses the Ekind E_Exception_Type.
5136 -- A generic function. This is the entity for a generic function
5137 -- created by a generic subprogram declaration.
5139 E_Generic_Procedure
,
5140 -- A generic function. This is the entity for a generic procedure
5141 -- created by a generic subprogram declaration.
5144 -- A generic package, this is the entity for a generic package created
5145 -- by a generic package declaration.
5148 -- The defining entity for a label. Note that this is created by the
5149 -- implicit label declaration, not the occurrence of the label itself,
5150 -- which is simply a direct name referring to the label.
5153 -- A loop identifier, created by an explicit or implicit label on a
5157 -- A dummy entity created for each return statement. Used to hold
5158 -- information about the return statement (what it applies to) and in
5159 -- rules checking. For example, a simple_return_statement that applies
5160 -- to an extended_return_statement cannot have an expression; this
5161 -- requires putting the E_Return_Statement entity for the
5162 -- extended_return_statement on the scope stack.
5165 -- A package, created by a package declaration
5168 -- A package body. This entity serves only limited functions, since
5169 -- most semantic analysis uses the package entity (E_Package). However
5170 -- there are some attributes that are significant for the body entity.
5171 -- For example, collection of exception handlers.
5174 -- A protected object, created by an object declaration that declares
5175 -- an object of a protected type.
5178 -- A protected body. This entity serves almost no function, since all
5179 -- semantic analysis uses the protected entity (E_Protected_Type).
5182 -- A task body. This entity serves almost no function, since all
5183 -- semantic analysis uses the protected entity (E_Task_Type).
5186 -- A subprogram body. Used when a subprogram has a separate declaration
5187 -- to represent the entity for the body. This entity serves almost no
5188 -- function, since all semantic analysis uses the subprogram entity
5189 -- for the declaration (E_Function or E_Procedure).

6813 -- Since E_Void is the initial Ekind value of an entity when it is first

6816 -- are many instances in which fields of an E_Void entity are set in the
6817 -- code prior to setting the Ekind field. This is not well documented or
6818 -- well controlled, and needs cleaning up later. Meanwhile, the access
6819 -- procedures in the body of Einfo permit many, but not all, attributes
6820 -- to be applied to an E_Void entity, precisely so that this kind of
6821 -- pre-setting of attributes works. This is really a hole in the dynamic
6822 -- type checking, since there is no assurance that the eventual Ekind

6828 -- Component_Alignment Control --
6829 ---------------------------------
6831 -- There are four types of alignment possible for array and record
6832 -- types, and a field in the type entities contains a value of the
6833 -- following type indicating which alignment choice applies. For full
6834 -- details of the meaning of these alignment types, see description
6835 -- of the Component_Alignment pragma.
6837 type Component_Alignment_Kind
is (
6838 Calign_Default
, -- default alignment
6839 Calign_Component_Size
, -- natural alignment for component size
6840 Calign_Component_Size_4
, -- natural for size <= 4, 4 for size >= 4
6841 Calign_Storage_Unit
); -- all components byte aligned
6843 -----------------------------------
6844 -- Floating Point Representation --
6845 -----------------------------------
6847 type Float_Rep_Kind
is (
6848 IEEE_Binary
, -- IEEE 754p conforming binary format
6849 AAMP
); -- AAMP format
6855 -- In addition to attributes that are stored as plain data, other
6856 -- attributes are procedural, and require some small amount of
6857 -- computation. Of course, from the point of view of a user of this
6858 -- package, the distinction is not visible (even the field information
6859 -- provided below should be disregarded, as it is subject to change
6860 -- without notice). A number of attributes appear as lists: lists of
6861 -- formals, lists of actuals, of discriminants, etc. For these, pairs
6862 -- of functions are defined, which take the form:
6864 -- function First_Thing (E : Enclosing_Construct) return Thing;
6865 -- function Next_Thing (T : Thing) return Thing;
6867 -- The end of iteration is always signaled by a value of Empty, so that
6868 -- loops over these chains invariably have the form:
6872 -- This := First_Thing (E);
6874 -- while Present (This) loop
6875 -- Do_Something_With (This);
6877 -- This := Next_Thing (This);
6880 -----------------------------------
6881 -- Handling of Check Suppression --
6882 -----------------------------------
6884 -- There are three ways that checks can be suppressed:
6886 -- 1. At the command line level
6887 -- 2. At the scope level.
6888 -- 3. At the entity level.
6890 -- See spec of Sem in sem.ads for details of the data structures used
6891 -- to keep track of these various methods for suppressing checks.
6893 -------------------------------
6894 -- Handling of Discriminants --
6895 -------------------------------
6897 -- During semantic processing, discriminants are separate entities which
6898 -- reflect the semantic properties and allowed usage of discriminants in
6901 -- In the case of discriminants used as bounds, the references are handled
6902 -- directly, since special processing is needed in any case. However, there
6903 -- are two circumstances in which discriminants are referenced in a quite
6904 -- general manner, like any other variables:
6906 -- In initialization expressions for records. Note that the expressions
6907 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline
6908 -- pragmas are effectively in this category, since these pragmas are
6909 -- converted to initialized record fields in the Corresponding_Record_
6912 -- In task and protected bodies, where the discriminant values may be
6913 -- referenced freely within these bodies. Discriminants can also appear
6914 -- in bounds of entry families and in defaults of operations.
6916 -- In both these cases, the discriminants must be treated essentially as
6917 -- objects. The following approach is used to simplify and minimize the
6918 -- special processing that is required.
6920 -- When a record type with discriminants is analyzed, semantic processing
6921 -- creates the entities for the discriminants. It also creates additional
6922 -- sets of entities called discriminals, one for each of the discriminants,
6923 -- and the Discriminal field of the discriminant entity points to this
6924 -- additional entity, which is initially created as an uninitialized
6927 -- During expansion of expressions, any discriminant reference is replaced
6928 -- by a reference to the corresponding discriminal. When the initialization
6929 -- procedure for the record is created (there will always be one, since
6930 -- discriminants are present, see Exp_Ch3 for further details), the
6931 -- discriminals are used as the entities for the formal parameters of
6932 -- this initialization procedure. The references to these discriminants
6933 -- have already been replaced by references to these discriminals, which
6934 -- are now the formal parameters corresponding to the required objects.
6936 -- In the case of a task or protected body, the semantics similarly creates
6937 -- a set of discriminals for the discriminants of the task or protected
6938 -- type. When the procedure is created for the task body, the parameter
6939 -- passed in is a reference to the task value type, which contains the
6940 -- required discriminant values. The expander creates a set of declarations
6943 -- discr_nameD : constant discr_type renames _task.discr_name;
6945 -- where discr_nameD is the discriminal entity referenced by the task
6946 -- discriminant, and _task is the task value passed in as the parameter.
6947 -- Again, any references to discriminants in the task body have been
6948 -- replaced by the discriminal reference, which is now an object that
6949 -- contains the required value.
6951 -- This approach for tasks means that two sets of discriminals are needed
6952 -- for a task type, one for the initialization procedure, and one for the
6953 -- task body. This works out nicely, since the semantics allocates one set
6954 -- for the task itself, and one set for the corresponding record.
6956 -- The one bit of trickiness arises in making sure that the right set of
6957 -- discriminals is used at the right time. First the task definition is
6958 -- processed. Any references to discriminants here are replaced by the
6959 -- corresponding *task* discriminals (the record type doesn't even exist
6960 -- yet, since it is constructed as part of the expansion of the task
6961 -- declaration, which happens after the semantic processing of the task
6962 -- definition). The discriminants to be used for the corresponding record
6963 -- are created at the same time as the other discriminals, and held in the
6964 -- CR_Discriminant field of the discriminant. A use of the discriminant in
6965 -- a bound for an entry family is replaced with the CR_Discriminant because
6966 -- it controls the bound of the entry queue array which is a component of
6967 -- the corresponding record.
6969 -- Just before the record initialization routine is constructed, the
6970 -- expander exchanges the task and record discriminals. This has two
6971 -- effects. First the generation of the record initialization routine
6972 -- uses the discriminals that are now on the record, which is the set
6973 -- that used to be on the task, which is what we want.
6975 -- Second, a new set of (so far unused) discriminals is now on the task
6976 -- discriminants, and it is this set that will be used for expanding the
6977 -- task body, and also for the discriminal declarations at the start of
6980 ---------------------------------------------------
6981 -- Handling of private data in protected objects --
6982 ---------------------------------------------------
6984 -- Private components in protected types pose problems similar to those
6985 -- of discriminants. Private data is visible and can be directly referenced
6986 -- from protected bodies. However, when protected entries and subprograms
6987 -- are expanded into corresponding bodies and barrier functions, private
6988 -- components lose their original context and visibility.
6990 -- To remedy this side effect of expansion, private components are expanded
6991 -- into renamings called "privals", by analogy with "discriminals".
6993 -- private_comp : comp_type renames _object.private_comp;
6995 -- Prival declarations are inserted during the analysis of subprogram and
6996 -- entry bodies to ensure proper visibility for any subsequent expansion.
6997 -- _Object is the formal parameter of the generated corresponding body or
6998 -- a local renaming which denotes the protected object obtained from entry
6999 -- parameter _O. Privals receive minimal decoration upon creation and are
7000 -- categorized as either E_Variable for the general case or E_Constant when
7001 -- they appear in functions.
7003 -- Along with the local declarations, each private component carries a
7004 -- placeholder which references the prival entity in the current body. This
7005 -- form of indirection is used to resolve name clashes of privals and other
7006 -- locally visible entities such as parameters, local objects, entry family
7007 -- indexes or identifiers used in the barrier condition.
7009 -- When analyzing the statements of a protected subprogram or entry, any
7010 -- reference to a private component must resolve to the locally declared
7011 -- prival through normal visibility. In case of name conflicts (the cases
7012 -- above), the prival is marked as hidden and acts as a weakly declared
7013 -- entity. As a result, the reference points to the correct entity. When a
7014 -- private component is denoted by an expanded name (prot_type.comp for
7015 -- example), the expansion mechanism uses the placeholder of the component
7016 -- to correct the Entity and Etype of the reference.
7022 -- The following type synonyms are used to tidy up the function and
7023 -- procedure declarations that follow, and also to make it possible to meet
7024 -- the requirement for the XEINFO utility that all function specs must fit
7025 -- on a single source line.

7688 -- value is set, then Known is False and Unknown is True. The Known_Static
7689 -- predicate is true only if the value is set (Known) and is set to a
7690 -- compile time known value. Note that in the case of Alignment and
7691 -- Normalized_First_Bit, dynamic values are not possible, so we do not
7692 -- need a separate Known_Static calls in these cases. The not set (unknown)
7693 -- values are as follows:
7695 -- Alignment Uint_0 or No_Uint
7696 -- Component_Size Uint_0 or No_Uint
7697 -- Component_Bit_Offset No_Uint
7698 -- Digits_Value Uint_0 or No_Uint
7699 -- Esize Uint_0 or No_Uint
7700 -- Normalized_First_Bit No_Uint
7701 -- Normalized_Position No_Uint
7702 -- Normalized_Position_Max No_Uint
7703 -- RM_Size Uint_0 or No_Uint
7705 -- It would be cleaner to use No_Uint in all these cases, but historically
7706 -- we chose to use Uint_0 at first, and the change over will take time ???
7707 -- This is particularly true for the RM_Size field, where a value of zero
7708 -- is legitimate. We deal with this by a considering that the value is
7709 -- always known static for discrete types (and no other types can have
7710 -- an RM_Size value of zero).
7712 -- In two cases, Known_Static_Esize and Known_Static_RM_Size, there is one
7713 -- more consideration, which is that we always return False for generic
7714 -- types. Within a template, the size can look known, because of the fake
7715 -- size values we put in template types, but they are not really known and
7716 -- anyone testing if they are known within the template should get False as
7717 -- a result to prevent incorrect assumptions.
