40 -- This package defines the annotations to the abstract syntax tree that
41 -- are needed to support semantic processing of an Ada compilation.
43 -- Note that after editing this spec and the corresponding body it is
44 -- required to run ceinfo to check the consistentcy of spec and body.
45 -- See ceinfo.adb for more information about the checks made.
47 -- These annotations are for the most part attributes of declared entities,
48 -- and they correspond to conventional symbol table information. Other
49 -- attributes include sets of meanings for overloaded names, possible
50 -- types for overloaded expressions, flags to indicate deferred constants,
51 -- incomplete types, etc. These attributes are stored in available fields
52 -- in tree nodes (i.e. fields not used by the parser, as defined by the
53 -- Sinfo package specification), and accessed by means of a set of
54 -- subprograms which define an abstract interface.
56 -- There are two kinds of semantic information
58 -- First, the tree nodes with the following Nkind values:
60 -- N_Defining_Identifier
61 -- N_Defining_Character_Literal
62 -- N_Defining_Operator_Symbol
64 -- are called Entities, and constitute the information that would often
65 -- be stored separately in a symbol table. These nodes are all extended
66 -- to provide extra space, and contain fields which depend on the entity
67 -- kind, as defined by the contents of the Ekind field. The use of the
68 -- Ekind field, and the associated fields in the entity, are defined
69 -- in this package, as are the access functions to these fields.
71 -- Second, in some cases semantic information is stored directly in other
72 -- kinds of nodes, e.g. the Etype field, used to indicate the type of an
73 -- expression. The access functions to these fields are defined in the
74 -- Sinfo package, but their full documentation is to be found in
75 -- the Einfo package specification.
77 -- Declaration processing places information in the nodes of their defining
78 -- identifiers. Name resolution places in all other occurrences of an
79 -- identifier a pointer to the corresponding defining occurrence.
81 --------------------------------
82 -- The XEINFO Utility Program --
83 --------------------------------
85 -- XEINFO is a utility program which automatically produces a C header file,
86 -- einfo.h from the spec and body of package Einfo. It reads the input
87 -- files einfo.ads and einfo.adb and produces the output file einfo.h.
88 -- XEINFO is run automatically by the build scripts when you do a full
91 -- In order for this utility program to operate correctly, the form of the
92 -- einfo.ads and einfo.adb files must meet certain requirements and be laid
93 -- out in a specific manner.
95 -- The general form of einfo.ads is as follows:
97 -- type declaration for type Entity_Kind
98 -- subtype declarations declaring subranges of Entity_Kind
99 -- subtype declarations declaring synonyms for some standard types
100 -- function specs for attributes
102 -- pragma Inline declarations
104 -- This order must be observed. There are no restrictions on the procedures,
105 -- since the C header file only includes functions (Gigi is not allowed to
106 -- modify the generated tree). However, functions are required to have headers
107 -- that fit on a single line.
109 -- XEINFO reads and processes the function specs and the pragma Inlines. For
110 -- functions that are declared as inlined, XEINFO reads the corresponding body
111 -- from einfo.adb, and processes it into C code. This results in some strict
112 -- restrictions on which functions can be inlined:
114 -- The function spec must be on a single line
116 -- There can only be a single statement, contained on a single line,
117 -- not counting any pragma Assert statements.
119 -- This single statement must either be a function call with simple,
120 -- single token arguments, or it must be a membership test of the form
121 -- a in b, where a and b are single tokens.
123 -- For functions that are not inlined, there is no restriction on the body,
124 -- and XEINFO generates a direct reference in the C header file which allows
125 -- the C code in Gigi to directly call the corresponding Ada body.
127 ----------------------------------
128 -- Handling of Type'Size Values --
129 ----------------------------------
131 -- The Ada 95 RM contains some rather peculiar (to us!) rules on the value
132 -- of type'Size (see RM 13.3(55)). We have found that attempting to use
133 -- these RM Size values generally, and in particular for determining the
134 -- default size of objects, creates chaos, and major incompatibilies in
137 -- We proceed as follows, for discrete and fixed-point subtypes, we have
138 -- two separate sizes for each subtype:
140 -- The Object_Size, which is used for determining the default size of
141 -- objects and components. This size value can be referred to using the
142 -- Object_Size attribute. The phrase "is used" here means that it is
143 -- the basis of the determination of the size. The backend is free to
144 -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
145 -- character might be stored in 32 bits on a machine with no efficient
146 -- byte access instructions such as the Alpha.
148 -- The default rules for the value of Object_Size for fixed-point and
149 -- discrete types are as follows:
151 -- The Object_Size for base subtypes reflect the natural hardware
152 -- size in bits (see Ttypes and Cstand for integer types). For
153 -- enumeration and fixed-point base subtypes have 8. 16. 32 or 64
154 -- bits for this size, depending on the range of values to be stored.
156 -- The Object_Size of a subtype is the same as the Object_Size of
157 -- the subtype from which it is obtained.
159 -- The Object_Size of a derived base type is copied from the parent
160 -- base type, and the Object_Size of a derived first subtype is copied
161 -- from the parent first subtype.
163 -- The Value_Size which is the number of bits required to store a value
164 -- of the type. This size can be referred to using the Value_Size
165 -- attribute. This value is used to determine how tightly to pack
166 -- records or arrays with components of this type, and also affects
167 -- the semantics of unchecked conversion (unchecked conversions where
168 -- the Value_Size values differ generate a warning, and are potentially
169 -- target dependent).
171 -- The default rule for the value of Value_Size are as follows:
173 -- The Value_Size for a base subtype is the minimum number of bits
174 -- required to store all values of the type (including the sign bit
175 -- only if negative values are possible).
177 -- If a subtype statically matches the first subtype, then it has
178 -- by default the same Value_Size as the first subtype. This is a
179 -- consequence of RM 13.1(14) ("if two subtypes statically match,
180 -- then their subtype-specific aspects are the same".)
182 -- All other subtypes have a Value_Size corresponding to the minimum
183 -- number of bits required to store all values of the subtype. For
184 -- dynamic bounds, it is assumed that the value can range down or up
185 -- to the corresponding bound of the ancestor
187 -- The RM defined attribute Size corresponds to the Value_Size attribute
189 -- The Size attribute may be defined for a first-named subtype. This sets
190 -- the Value_Size of the first-named subtype to the given value, and the
191 -- Object_Size of this first-named subtype to the given value padded up
192 -- to an appropriate boundary. It is a consequence of the default rules
193 -- above that this Object_Size will apply to all further subtypes. On the
194 -- other hand, Value_Size is affected only for the first subtype, any
195 -- dynamic subtypes obtained from it directly, and any statically matching
196 -- subtypes. The Value_Size of any other static subtypes is not affected.
198 -- Value_Size and Object_Size may be explicitly set for any subtype using
199 -- an attribute definition clause. Note that the use of these attributes
200 -- can cause the RM 13.1(14) rule to be violated. If two access types
201 -- reference aliased objects whose subtypes have differing Object_Size
202 -- values as a result of explicit attribute definition clauses, then it
203 -- is erroneous to convert from one access subtype to the other.
205 -- At the implementation level, Esize stores the Object_Size and the
206 -- RM_Size field stores the Value_Size (and hence the value of the
207 -- Size attribute, which, as noted above, is equivalent to Value_Size).
209 -- To get a feel for the difference, consider the following examples (note
210 -- that in each case the base is short_short_integer with a size of 8):
212 -- Object_Size Value_Size
214 -- type x1 is range 0..5; 8 3
216 -- type x2 is range 0..5;
217 -- for x2'size use 12; 16 12
219 -- subtype x3 is x2 range 0 .. 3; 16 2
221 -- subtype x4 is x2'base range 0 .. 10; 8 4
223 -- subtype x5 is x2 range 0 .. dynamic; 16 (7)
225 -- subtype x6 is x2'base range 0 .. dynamic; 8 (7)
227 -- Note: the entries marked (7) are not actually specified by the Ada 95 RM,
228 -- but it seems in the spirit of the RM rules to allocate the minimum number
229 -- of bits known to be large enough to hold the given range of values.
231 -- So far, so good, but GNAT has to obey the RM rules, so the question is
232 -- under what conditions must the RM Size be used. The following is a list
233 -- of the occasions on which the RM Size must be used:
235 -- Component size for packed arrays or records
236 -- Value of the attribute Size for a type
237 -- Warning about sizes not matching for unchecked conversion
239 -- The RM_Size field keeps track of the RM Size as needed in these
242 -- For elementary types other than discrete and fixed-point types, the
243 -- Object_Size and Value_Size are the same (and equivalent to the RM
244 -- attribute Size). Only Size may be specified for such types.
246 -- For composite types, Object_Size and Value_Size are computed from their
247 -- respective value for the type of each element as well as the layout.
249 -- All size attributes are stored as Uint values. Negative values are used to
250 -- reference GCC expressions for the case of non-static sizes, as explained
253 --------------------------------------
254 -- Delayed Freezing and Elaboration --
255 --------------------------------------
257 -- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
258 -- freeze node, which appears later in the expanded tree.
260 -- a) The flag is used by the front-end to trigger expansion actions which
261 -- include the generation of that freeze node. Typically this happens at the
262 -- end of the current compilation unit, or before the first subprogram body is
263 -- encountered in the current unit. See files freeze and exp_ch13 for details
264 -- on the actions triggered by a freeze node, which include the construction
265 -- of initialization procedures and dispatch tables.
267 -- b) The presence of a freeze node on an entity is used by the backend to
268 -- defer elaboration of the entity until its freeze node is seen. In the
269 -- absence of an explicit freeze node, an entity is frozen (and elaborated)
270 -- at the point of declaration.
272 -- For object declarations, the flag is set when an address clause for the
273 -- object is encountered. Legality checks on the address expression only take
274 -- place at the freeze point of the object.
276 -- Most types have an explicit freeze node, because they cannot be elaborated
277 -- until all representation and operational items that apply to them have been
278 -- analyzed. Private types and incomplete types have the flag set as well, as
279 -- do task and protected types.
281 -- Implicit base types created for type derivations, as well as classwide
282 -- types created for all tagged types, have the flag set.
284 -- If a subprogram has an access parameter whose designated type is incomplete
285 -- the subprogram has the flag set.
287 -----------------------
288 -- Entity Attributes --
289 -----------------------
291 -- This section contains a complete list of the attributes that are defined
292 -- on entities. Some attributes apply to all entities, others only to certain
293 -- kinds of entities. In the latter case the attribute should only be set or
294 -- accessed if the Ekind field indicates an appropriate entity.
296 -- There are two kinds of attributes that apply to entities, stored and
297 -- synthesized. Stored attributes correspond to a field or flag in the entity
298 -- itself. Such attributes are identified in the table below by giving the
299 -- field or flag in the attribute that is used to hold the attribute value.
300 -- Synthesized attributes are not stored directly, but are rather computed as
301 -- needed from other attributes, or from information in the tree. These are
302 -- marked "synthesized" in the table below. The stored attributes have both
303 -- access functions and set procedures to set the corresponding values, while
304 -- synthesized attributes have only access functions.
306 -- Note: in the case of Node, Uint, or Elist fields, there are cases where
307 -- the same physical field is used for different purposes in different
308 -- entities, so these access functions should only be referenced for the
309 -- class of entities in which they are defined as being present. Flags are
310 -- not overlapped in this way, but nevertheless as a matter of style and
311 -- abstraction (which may or may not be checked by assertions in the body),
312 -- this restriction should be observed for flag fields as well.
314 -- Note: certain of the attributes on types apply only to base types, and
315 -- are so noted by the notation [base type only]. These are cases where the
316 -- attribute of any subtype is the same as the attribute of the base type.
317 -- The attribute can be referenced on a subtype (and automatically retrieves
318 -- the value from the base type). However, it is an error to try to set the
319 -- attribute on other than the base type, and if assertions are enabled,
320 -- an attempt to set the attribute on a subtype will raise an assert error.
322 -- Other attributes are noted as applying to the [implementation base type
323 -- only]. These are representation attributes which must always apply to a
324 -- full non-private type, and where the attributes are always on the full
325 -- type. The attribute can be referenced on a subtype (and automatically
326 -- retries the value from the implementation base type). However, it is an
327 -- error to try to set the attribute on other than the implementation base
328 -- type, and if assertions are enabled, an attempt to set the attribute on a
329 -- subtype will raise an assert error.
331 -- Accept_Address (Elist21)
332 -- Present in entries. If an accept has a statement sequence, then an
333 -- address variable is created, which is used to hold the address of the
334 -- parameters, as passed by the runtime. Accept_Address holds an element
335 -- list which represents a stack of entities for these address variables.
336 -- The current entry is the top of the stack, which is the last element
337 -- on the list. A stack is required to handle the case of nested select
338 -- statements referencing the same entry.
340 -- Actual_Subtype (Node17)
341 -- Present in variables, constants, and formal parameters. This is the
342 -- subtype imposed by the value of the object, as opposed to its nominal
343 -- subtype, which is imposed by the declaration. The actual subtype
344 -- differs from the nominal one when the latter is indefinite (as in the
345 -- case of an unconstrained formal parameter, or a variable declared
346 -- with an unconstrained type and an initial value). The nominal subtype
347 -- is the Etype entry for the entity. The Actual_Subtype field is set
348 -- only if the actual subtype differs from the nominal subtype. If the
349 -- actual and nominal subtypes are the same, then the Actual_Subtype
350 -- field is Empty, and Etype indicates both types.
352 -- For objects, the Actual_Subtype is set only if this is a discriminated
353 -- type. For arrays, the bounds of the expression are obtained and the
354 -- Etype of the object is directly the constrained subtype. This is
355 -- rather irregular, and the semantic checks that depend on the nominal
356 -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
358 -- Access_Disp_Table (Elist16) [implementation base type only]
359 -- Present in record type entities. For a tagged type, points to the
360 -- dispatch tables associated with the tagged type. The first two
361 -- entities correspond with the primary dispatch table: 1) primary
362 -- dispatch table with user-defined primitives, 2) primary dispatch table
363 -- with predefined primitives. For each interface type covered by the
364 -- tagged type we also have: 3) secondary dispatch table with thunks of
365 -- primitives covering user-defined interface primitives, 4) secondary
366 -- dispatch table with thunks of predefined primitives, 5) secondary
367 -- dispatch table with user-defined primitives, and 6) secondary dispatch
368 -- table with predefined primitives. The last entity of this list is an
369 -- access type declaration used to expand dispatching calls through the
370 -- primary dispatch table. For a non-tagged record, contains Empty.
372 -- Address_Clause (synthesized)
373 -- Applies to entries, objects and subprograms. Set if an address clause
374 -- is present which references the object or subprogram and points to
375 -- the N_Attribute_Definition_Clause node. Empty if no Address clause.
376 -- The expression in the address clause is always a constant that is
377 -- defined before the entity to which the address clause applies.
378 -- Note: Gigi references this field in E_Task_Type entities???
380 -- Address_Taken (Flag104)
381 -- Present in all entities. Set if the Address or Unrestricted_Access
382 -- attribute is applied directly to the entity, i.e. the entity is the
383 -- entity of the prefix of the attribute reference. Used by Gigi to
384 -- make sure that the address can be meaningfully taken, and also in
385 -- the case of subprograms to control output of certain warnings.
387 -- Aft_Value (synthesized)
388 -- Applies to fixed and decimal types. Computes a universal integer
389 -- that holds value of the Aft attribute for the type.
392 -- Present in overloaded entities (literals, subprograms, entries) and
393 -- subprograms that cover a primitive operation of an abstract interface
394 -- (that is, subprograms with the Interface_Alias attribute). In case of
395 -- overloaded entities it points to the parent subprogram of a derived
396 -- subprogram. In case of abstract interface subprograms it points to the
397 -- subprogram that covers the abstract interface primitive. Also used for
398 -- a subprogram renaming, where it points to the renamed subprogram. For
399 -- an inherited operation (of a type extension) that is overridden in a
400 -- private part, the Alias is the overriding operation. In this fashion a
401 -- call from outside the package ends up executing the new body even if
402 -- non-dispatching, and a call from inside calls the overriding operation
403 -- because it hides the implicit one. Alias is always empty for entries.
405 -- Alignment (Uint14)
406 -- Present in entities for types and also in constants, variables
407 -- (including exceptions where it refers to the static data allocated for
408 -- an exception), loop parameters, and formal parameters. This indicates
409 -- the desired alignment for a type, or the actual alignment for an
410 -- object. A value of zero (Uint_0) indicates that the alignment has not
411 -- been set yet. The alignment can be set by an explicit alignment
412 -- clause, or set by the front-end in package Layout, or set by the
413 -- back-end as part of the back end back-annotation process. The
414 -- alignment field is also present in E_Exception entities, but there it
415 -- is used only by the back-end for back annotation.
417 -- Alignment_Clause (synthesized)
418 -- Applies to all entities for types and objects. If an alignment
419 -- attribute definition clause is present for the entity, then this
420 -- function returns the N_Attribute_Definition clause that specifies the
421 -- alignment. If no alignment clause applies to the type, then the call
422 -- to this function returns Empty. Note that the call can return a
423 -- non-Empty value even if Has_Alignment_Clause is not set (happens with
424 -- subtype and derived type declarations). Note also that a record
425 -- definition clause with an (obsolescent) mod clause is converted
426 -- into an attribute definition clause for this purpose.
428 -- Associated_Formal_Package (Node12)
429 -- Present in packages that are the actuals of formal_packages. Points
430 -- to the entity in the declaration for the formal package.
432 -- Associated_Node_For_Itype (Node8)
433 -- Present in all type and subtype entities. Set non-Empty only for
434 -- Itypes. Set to point to the associated node for the Itype, i.e.
435 -- the node whose elaboration generated the Itype. This is used for
436 -- copying trees, to determine whether or not to copy an Itype, and
437 -- also for accessibility checks on anonymous access types. This
438 -- node is typically an object declaration, component declaration,
439 -- type or subtype declaration. For an access discriminant in a type
440 -- declaration, the associated_node_for_itype is the discriminant
441 -- specification. For an access parameter it is the enclosing subprogram
444 -- Associated_Storage_Pool (Node22) [root type only]
445 -- Present in simple and general access type entities. References the
446 -- storage pool to be used for the corresponding collection. A value of
447 -- Empty means that the default pool is to be used. This is present
448 -- only in the root type, since derived types must have the same pool
449 -- as the parent type.
451 -- Associated_Final_Chain (Node23)
452 -- Present in simple and general access type entities. References the
453 -- List_Controller object that holds the finalization chain on which
454 -- are attached dynamically allocated objects referenced by the access
455 -- type. Empty when the access type cannot reference a controlled object.
457 -- Barrier_Function (Node12)
458 -- Present in protected entries and entry families. This is the
459 -- subprogram declaration for the body of the function that returns
460 -- the value of the entry barrier.
462 -- Base_Type (synthesized)
463 -- Applies to all type entities. Returns the base type of a type or
464 -- subtype. The base type of a type is the type itself. The base type
465 -- of a subtype is the type that it constrains (which is always a type
466 -- entity, not some other subtype). Note that in the case of a subtype
467 -- of a private type, it is possible for the base type attribute to
468 -- return a private type, even if the subtype to which it applies is
469 -- non-private. See also Implementation_Base_Type. Note: it is allowed
470 -- to apply Base_Type to other than a type, in which case it simply
471 -- returns the entity unchanged.
473 -- Block_Node (Node11)
474 -- Present in block entities. Points to the identifier in the
475 -- Block_Statement itself. Used when retrieving the block construct
476 -- for finalization purposes, The block entity has an implicit label
477 -- declaration in the enclosing declarative part, and has otherwise
478 -- no direct connection in the tree with the block statement. The
479 -- link is to the identifier (which is an occurrence of the entity)
480 -- and not to the block_statement itself, because the statement may
481 -- be rewritten, e.g. in the process of removing dead code.
483 -- Body_Entity (Node19)
484 -- Present in package and generic package entities, points to the
485 -- corresponding package body entity if one is present.
487 -- Body_Needed_For_SAL (Flag40)
488 -- Present in package and subprogram entities that are compilation
489 -- units. Indicates that the source for the body must be included
490 -- when the unit is part of a standalone library.
492 -- C_Pass_By_Copy (Flag125) [implementation base type only]
493 -- Present in record types. Set if a pragma Convention for the record
494 -- type specifies convention C_Pass_By_Copy. This convention name is
495 -- treated as identical in all respects to convention C, except that
496 -- if it is specified for a record type, then the C_Pass_By_Copy flag
497 -- is set, and if a foreign convention subprogram has a formal of the
498 -- corresponding type, then the parameter passing mechanism will be
499 -- set to By_Copy (unless specifically overridden by an Import or
502 -- Can_Never_Be_Null (Flag38)
503 -- This flag is present in all entities, but can only be set in an object
504 -- which can never have a null value. This is set True for constant
505 -- access values initialized to a non-null value. This is also True for
506 -- all access parameters in Ada 83 and Ada 95 modes, and for access
507 -- parameters that explicily exlude null in Ada 2005.
509 -- This is used to avoid unnecessary resetting of the Is_Known_Non_Null
510 -- flag for such entities. In Ada 2005 mode, this is also used when
511 -- determining subtype conformance of subprogram profiles to ensure
512 -- that two formals have the same null-exclusion status.
514 -- ??? This is also set on some access types, eg the Etype of the
515 -- anonymous access type of a controlling formal.
518 -- Present in all entities. This field contains an entry into the names
519 -- table that has the character string of the identifier, character
520 -- literal or operator symbol. See Namet for further details. Note that
521 -- throughout the processing of the front end, this name is the simple
522 -- unqualified name. However, just before gigi is called, a call is made
523 -- to Qualify_All_Entity_Names. This causes entity names to be qualified
524 -- using the encoding described in exp_dbug.ads, and from that point on
525 -- (including post gigi steps such as cross-reference generation), the
526 -- entities will contain the encoded qualified names.
528 -- Checks_May_Be_Suppressed (Flag31)
529 -- Present in all entities. Set if a pragma Suppress or Unsuppress
530 -- mentions the entity specifically in the second argument. If this
531 -- flag is set the Global_Entity_Suppress and Local_Entity_Suppress
532 -- tables must be consulted to determine if there actually is an active
533 -- Suppress or Unsuppress pragma that applies to the entity.
535 -- Class_Wide_Type (Node9)
536 -- Present in all type entities. For a tagged type or subtype, returns
537 -- the corresponding implicitly declared class-wide type. Set to Empty
538 -- for non-tagged types.
540 -- Cloned_Subtype (Node16)
541 -- Present in E_Record_Subtype and E_Class_Wide_Subtype entities.
542 -- Each such entity can either have a Discriminant_Constraint, in
543 -- which case it represents a distinct type from the base type (and
544 -- will have a list of components and discrimants in the list headed by
545 -- First_Entity) or else no such constraint, in which case it will be a
546 -- copy of the base type.
548 -- o Each element of the list in First_Entity is copied from the base
549 -- type; in that case, this field is Empty.
551 -- o The list in First_Entity is shared with the base type; in that
552 -- case, this field points to that entity.
554 -- A record or classwide subtype may also be a copy of some other
555 -- subtype and share the entities in the First_Entity with that subtype.
556 -- In that case, this field points to that subtype.
558 -- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
559 -- this field. Note that this field ONLY appears in subtype entries, not
560 -- in type entries, it is not present, and it is an error to reference
561 -- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
564 -- This flag appears on all nodes, including entities, and indicates
565 -- that the node was created by the scanner or parser from the original
566 -- source. Thus for entities, it indicates that the entity is defined
567 -- in the original source program.
569 -- Component_Alignment (special field) [base type only]
570 -- Present in array and record entities. Contains a value of type
571 -- Component_Alignment_Kind indicating the alignment of components.
572 -- Set to Calign_Default normally, but can be overridden by use of
573 -- the Component_Alignment pragma. Note: this field is currently
574 -- stored in a non-standard way, see body for details.
576 -- Component_Bit_Offset (Uint11)
577 -- Present in record components (E_Component, E_Discriminant) if a
578 -- component clause applies to the component. First bit position of
579 -- given component, computed from the first bit and position values
580 -- given in the component clause. A value of No_Uint means that the
581 -- value is not yet known. The value can be set by the appearance of
582 -- an explicit component clause in a record representation clause,
583 -- or it can be set by the front-end in package Layout, or it can be
584 -- set by the backend. By the time backend processing is completed,
585 -- this field is always set. A negative value is used to represent
586 -- a value which is not known at compile time, and must be computed
587 -- at run-time (this happens if fields of a record have variable
588 -- lengths). See package Layout for details of these values.
590 -- Note: Component_Bit_Offset is redundant with respect to the fields
591 -- Normalized_First_Bit and Normalized_Position, and could in principle
592 -- be eliminated, but it is convenient in several situations, including
593 -- use in Gigi, to have this redundant field.
595 -- Component_Clause (Node13)
596 -- Present in record components and discriminants. If a record
597 -- representation clause is present for the corresponding record type a
598 -- that specifies a position for the component, then the Component_Clause
599 -- field of the E_Component entity points to the N_Component_Clause node.
600 -- Set to Empty if no record representation clause was present, or if
601 -- there was no specification for this component.
603 -- Component_Size (Uint22) [implementation base type only]
604 -- Present in array types. It contains the component size value for
605 -- the array. A value of No_Uint means that the value is not yet set.
606 -- The value can be set by the use of a component size clause, or
607 -- by the front end in package Layout, or by the backend. A negative
608 -- value is used to represent a value which is not known at compile
609 -- time, and must be computed at run-time (this happens if the type
610 -- of the component has a variable length size). See package Layout
611 -- for details of these values.
613 -- Component_Type (Node20) [implementation base type only]
614 -- Present in array types and string types. References component type.
616 -- Corresponding_Concurrent_Type (Node18)
617 -- Present in record types that are constructed by the expander to
618 -- represent task and protected types (Is_Concurrent_Record_Type flag
619 -- set True). Points to the entity for the corresponding task type or
622 -- Corresponding_Discriminant (Node19)
623 -- Present in discriminants of a derived type, when the discriminant is
624 -- used to constrain a discriminant of the parent type. Points to the
625 -- corresponding discriminant in the parent type. Otherwise it is Empty.
627 -- Corresponding_Equality (Node13)
628 -- Present in function entities for implicit inequality operators.
629 -- Denotes the explicit or derived equality operation that creates
630 -- the implicit inequality. Note that this field is not present in
631 -- other function entities, only in implicit inequality routines,
632 -- where Comes_From_Source is always False.
634 -- Corresponding_Record_Type (Node18)
635 -- Present in protected and task types and subtypes. References the
636 -- entity for the corresponding record type constructed by the expander
637 -- (see Exp_Ch9). This type is used to represent values of the task type.
639 -- Corresponding_Remote_Type (Node22)
640 -- Present in record types that describe the fat pointer structure for
641 -- Remote_Access_To_Subrogram types. References the original access type.
643 -- CR_Discriminant (Node23)
644 -- Present in discriminants of concurrent types. Denotes the homologous
645 -- discriminant of the corresponding record type. The CR_Discriminant is
646 -- created at the same time as the discriminal, and used to replace
647 -- occurrences of the discriminant within the type declaration.
649 -- Current_Use_Clause (Node27)
650 -- Present in packages and in types. For packages, denotes the use
651 -- package clause currently in scope that makes the package use_visible.
652 -- For types, it denotes the use_type clause that makes the operators of
653 -- the type visible. Used for more precise warning messages on redundant
656 -- Current_Value (Node9)
657 -- Present in all object entities. Set in E_Variable, E_Constant, formal
658 -- parameters and E_Loop_Parameter entities if we have trackable current
659 -- values. Set non-Empty if the (constant) current value of the variable
660 -- is known, This value is valid only for references from the same
661 -- sequential scope as the entity. The sequential scope of an entity
662 -- includes the immediate scope and any contained scopes that are package
663 -- specs, package bodies, blocks (at any nesting level) or statement
664 -- sequences in IF or loop statements.
666 -- Another related use of this field is to record information about the
667 -- value obtained from an IF or WHILE statement condition. If the IF or
668 -- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ",
669 -- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a
670 -- Current_Value field, RELOP is one of the six relational operators, and
671 -- VAL is a compile-time known value then the Current_Value field of OBJ
672 -- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node
673 -- of the relevant construct, and the Condition field of this can be
674 -- consulted to give information about the value of OBJ. For more details
675 -- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition.
677 -- Debug_Info_Off (Flag166)
678 -- Present in all entities. Set if a pragma Suppress_Debug_Info applies
679 -- to the entity, or if internal processing in the compiler determines
680 -- that suppression of debug information is desirable. Note that this
681 -- flag is only for use by the front end as part of the processing for
682 -- determining if Needs_Debug_Info should be set. The back end should
683 -- always test Needs_Debug_Info, it should never test Debug_Info_Off.
685 -- Debug_Renaming_Link (Node25)
686 -- Used to link the variable associated with a debug renaming declaration
687 -- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
688 -- details of the use of this field.
690 -- Declaration_Node (synthesized)
691 -- Applies to all entities. Returns the tree node for the declaration
692 -- that declared the entity. Normally this is just the Parent of the
693 -- entity. One exception arises with child units, where the parent of
694 -- the entity is a selected component or a defining program unit name.
695 -- Another exception is that if the entity is an incomplete type that
696 -- has been completed, then we obtain the declaration node denoted by
697 -- the full type, i.e. the full type declaration node.
699 -- Default_Expr_Function (Node21)
700 -- Present in parameters. It holds the entity of the parameterless
701 -- function that is built to evaluate the default expression if it is
702 -- more complex than a simple identifier or literal. For the latter
703 -- simple cases or if there is no default value, this field is Empty.
705 -- Default_Expressions_Processed (Flag108)
706 -- A flag in subprograms (functions, operators, procedures) and in
707 -- entries and entry families used to indicate that default expressions
708 -- have been processed and to avoid multiple calls to process the
709 -- default expressions (see Freeze.Process_Default_Expressions), which
710 -- would not only waste time, but also generate false error messages.
712 -- Default_Value (Node20)
713 -- Present in formal parameters. Points to the node representing the
714 -- expression for the default value for the parameter. Empty if the
715 -- parameter has no default value (which is always the case for OUT
716 -- and IN OUT parameters in the absence of errors).
718 -- Delay_Cleanups (Flag114)
719 -- Present in entities that have finalization lists (subprograms
720 -- blocks, and tasks). Set if there are pending generic body
721 -- instantiations for the corresponding entity. If this flag is
722 -- set, then generation of cleanup actions for the corresponding
723 -- entity must be delayed, since the insertion of the generic body
724 -- may affect cleanup generation (see Inline for further details).
726 -- Delay_Subprogram_Descriptors (Flag50)
727 -- Present in entities for which exception subprogram descriptors
728 -- are generated (subprograms, package declarations and package
729 -- bodies). Present if there are pending generic body instantiations
730 -- for the corresponding entity. If this flag is set, then generation
731 -- of the subprogram descriptor for the corresponding enities must
732 -- be delayed, since the insertion of the generic body may add entries
733 -- to the list of handlers.
735 -- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
736 -- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
737 -- a block (in which case Delay_Subprogram_Descriptors is set for the
738 -- containing subprogram). In addition Delay_Subprogram_Descriptors is
739 -- set for a library level package declaration or body which contains
740 -- delayed instantiations (in this case the descriptor refers to the
741 -- enclosing elaboration procedure).
743 -- Delta_Value (Ureal18)
744 -- Present in fixed and decimal types. Points to a universal real
745 -- that holds value of delta for the type, as given in the declaration
746 -- or as inherited by a subtype or derived type.
748 -- Dependent_Instances (Elist8)
749 -- Present in packages that are instances. Holds list of instances
750 -- of inner generics. Used to place freeze nodes for those instances
751 -- after that of the current one, i.e. after the corresponding generic
754 -- Depends_On_Private (Flag14)
755 -- Present in all type entities. Set if the type is private or if it
756 -- depends on a private type.
758 -- Designated_Type (synthesized)
759 -- Applies to access types. Returns the designated type. Differs
760 -- from Directly_Designated_Type in that if the access type refers
761 -- to an incomplete type, and the full type is available, then this
762 -- full type is returned instead of the incomplete type.
764 -- Digits_Value (Uint17)
765 -- Present in floating point types and subtypes and decimal types and
766 -- subtypes. Contains the Digits value specified in the declaration.
768 -- Directly_Designated_Type (Node20)
769 -- Present in access types. This field points to the type that is
770 -- directly designated by the access type. In the case of an access
771 -- type to an incomplete type, this field references the incomplete
772 -- type. Note that in the semantic processing, what is useful in
773 -- nearly all cases is the full type designated by the access type.
774 -- The function Designated_Type obtains this full type in the case of
775 -- access to an incomplete type.
777 -- Discard_Names (Flag88)
778 -- Present in types and exception entities. Set if pragma Discard_Names
779 -- applies to the entity. It is also set for declarative regions and
780 -- package specs for which a Discard_Names pragma with zero arguments
781 -- has been encountered. The purpose of setting this flag is to be able
782 -- to set the Discard_Names attribute on enumeration types declared
783 -- after the pragma within the same declarative region. This flag is
784 -- set to False if a Keep_Names pragma appears for an enumeration type.
786 -- Discriminal (Node17)
787 -- Present in discriminants (Discriminant formal: GNAT's first
788 -- coinage). The entity used as a formal parameter that corresponds
789 -- to a discriminant. See section "Handling of Discriminants" for
790 -- full details of the use of discriminals.
792 -- Discriminal_Link (Node10)
793 -- Present in discriminals (which have an Ekind of E_In_Parameter,
794 -- or E_Constant), points back to corresponding discriminant.
796 -- Discriminant_Checking_Func (Node20)
797 -- Present in components. Points to the defining identifier of the
798 -- function built by the expander returns a Boolean indicating whether
799 -- the given record component exists for the current discriminant
802 -- Discriminant_Constraint (Elist21)
803 -- Present in entities whose Has_Discriminants flag is set (concurrent
804 -- types, subtypes, record types and subtypes, private types and
805 -- subtypes, limited private types and subtypes and incomplete types).
806 -- It is an error to reference the Discriminant_Constraint field if
807 -- Has_Discriminants is False.
809 -- If the Is_Constrained flag is set, Discriminant_Constraint points
810 -- to an element list containing the discriminant constraints in the
811 -- same order in which the discriminants are declared.
813 -- If the Is_Constrained flag is not set but the discriminants of the
814 -- unconstrained type have default initial values then this field
815 -- points to an element list giving these default initial values in
816 -- the same order in which the discriminants are declared. Note that
817 -- in this case the entity cannot be a tagged record type, because
818 -- discriminants in this case cannot have defaults.
820 -- If the entity is a tagged record implicit type, then this field is
821 -- inherited from the first subtype (so that the itype is subtype
822 -- conformant with its first subtype, which is needed when the first
823 -- subtype overrides primitive operations inherited by the implicit
826 -- In all other cases Discriminant_Constraint contains the empty
827 -- Elist (ie it is initialized with a call to New_Elmt_List).
829 -- Discriminant_Default_Value (Node20)
830 -- Present in discriminants. Points to the node representing the
831 -- expression for the default value of the discriminant. Set to
832 -- Empty if the discriminant has no default value.
834 -- Discriminant_Number (Uint15)
835 -- Present in discriminants. Gives the ranking of a discriminant in
836 -- the list of discriminants of the type, i.e. a sequential integer
837 -- index starting at 1 and ranging up to number of discriminants.
839 -- Dispatch_Table_Wrappers (Elist26) [implementation base type only]
840 -- Present in library level record type entities if we are generating
841 -- statically allocated dispatch tables. For a tagged type, points to
842 -- the list of dispatch table wrappers associated with the tagged type.
843 -- For a non-tagged record, contains No_Elist.
845 -- DTC_Entity (Node16)
846 -- Present in function and procedure entities. Set to Empty unless
847 -- the subprogram is dispatching in which case it references the
848 -- Dispatch Table pointer Component. That is to say the component _tag
849 -- for regular Ada tagged types, for CPP_Class types and their
850 -- descendants this field points to the component entity in the record
851 -- that is the Vtable pointer for the Vtable containing the entry that
852 -- references the subprogram.
854 -- DT_Entry_Count (Uint15)
855 -- Present in E_Component entities. Only used for component marked
856 -- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
858 -- DT_Offset_To_Top_Func (Node25)
859 -- Present in E_Component entities. Only used for component marked
860 -- Is_Tag. If present it stores the Offset_To_Top function used to
861 -- provide this value in tagged types whose ancestor has discriminants.
863 -- DT_Position (Uint15)
864 -- Present in function and procedure entities which are dispatching
865 -- (should not be referenced without first checking that flag
866 -- Is_Dispatching_Operation is True). Contains the offset into
867 -- the Vtable for the entry that references the subprogram.
870 -- Present in all entities. Contains a value of the enumeration type
871 -- Entity_Kind declared in a subsequent section in this spec.
873 -- Elaborate_Body_Desirable (Flag210)
874 -- Present in package entities. Set if the elaboration circuitry detects
875 -- a case where there is a package body that modifies one or more visible
876 -- entities in the package spec and there is no explicit Elaborate_Body
877 -- pragma for the package. This information is passed on to the binder,
878 -- which attempts, but does not promise, to elaborate the body as close
879 -- to the spec as possible.
881 -- Elaboration_Entity (Node13)
882 -- Present in generic and non-generic package and subprogram
883 -- entities. This is a boolean entity associated with the unit that
884 -- is initially set to False, and is set True when the unit is
885 -- elaborated. This is used for two purposes. First, it is used to
886 -- implement required access before elaboration checks (the flag
887 -- must be true to call a subprogram at elaboration time). Second,
888 -- it is used to guard against repeated execution of the generated
891 -- Note that we always allocate this flag, and set this field, but
892 -- we do not always actually use it. It is only used if it is needed
893 -- for access-before-elaboration use (see Elaboration_Entity_Required
894 -- flag) or if either the spec or the body has elaboration code. If
895 -- neither of these two conditions holds, then the entity is still
896 -- allocated (since we don't know early enough whether or not there
897 -- is elaboration code), but is simply not used for any purpose.
899 -- Elaboration_Entity_Required (Flag174)
900 -- Present in generics and non-generic package and subprogram
901 -- entities. Set only if Elaboration_Entity is non-Empty to indicate
902 -- that the boolean is required to be set even if there is no other
903 -- elaboration code. This occurs when the Elaboration_Entity flag
904 -- is used for required access-before-elaboration checking. If the
905 -- flag is only for preventing multiple execution of the elaboration
906 -- code, then if there is no other elaboration code, obviously there
907 -- is no need to set the flag.
909 -- Enclosing_Scope (Node18)
910 -- Present in labels. Denotes the innermost enclosing construct that
911 -- contains the label. Identical to the scope of the label, except for
912 -- labels declared in the body of an accept statement, in which case the
913 -- entry_name is the Enclosing_Scope. Used to validate goto's within
914 -- accept statements.
916 -- Entry_Accepted (Flag152)
917 -- Present in E_Entry and E_Entry_Family entities. Set if there is
918 -- at least one accept for this entry in the task body. Used to
919 -- generate warnings for missing accepts.
921 -- Entry_Bodies_Array (Node15)
922 -- Present in protected types for which Has_Entries is true.
923 -- This is the defining identifier for the array of entry body
924 -- action procedures and barrier functions used by the runtime to
925 -- execute the user code associated with each entry.
927 -- Entry_Cancel_Parameter (Node23)
928 -- Present in blocks. This only applies to a block statement for
929 -- which the Is_Asynchronous_Call_Block flag is set. It
930 -- contains the defining identifier of an object that must be
931 -- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
932 -- call in the cleanup handler added to the block by
933 -- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
934 -- object for task entry calls and a Communications_Block object
935 -- in the case of protected entry calls. In both cases the objects
936 -- are declared in outer scopes to this block.
938 -- Entry_Component (Node11)
939 -- Present in formal parameters (in, in out and out parameters). Used
940 -- only for formals of entries. References the corresponding component
941 -- of the entry parameter record for the entry.
943 -- Entry_Formal (Node16)
944 -- Present in components of the record built to correspond to entry
945 -- parameters. This field points from the component to the formal. It
946 -- is the back pointer corresponding to Entry_Component.
948 -- Entry_Index_Constant (Node18)
949 -- Present in an entry index parameter. This is an identifier that
950 -- eventually becomes the name of a constant representing the index
951 -- of the entry family member whose entry body is being executed. Used
952 -- to expand references to the entry index specification identifier.
954 -- Entry_Index_Type (synthesized)
955 -- Applies to an entry family. Denotes Etype of the subtype indication
956 -- in the entry declaration. Used to resolve the index expression in an
957 -- accept statement for a member of the family, and in the prefix of
958 -- 'COUNT when it applies to a family member.
960 -- Entry_Parameters_Type (Node15)
961 -- Present in entries. Points to the access-to-record type that is
962 -- constructed by the expander to hold a reference to the parameter
963 -- values. This reference is manipulated (as an address) by the
964 -- tasking runtime. The designated record represents a packaging
965 -- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
966 -- for further details). Entry_Parameters_Type is Empty if the entry
967 -- has no parameters.
969 -- Enumeration_Pos (Uint11)
970 -- Present in enumeration literals. Contains the position number
971 -- corresponding to the value of the enumeration literal.
973 -- Enumeration_Rep (Uint12)
974 -- Present in enumeration literals. Contains the representation that
975 -- corresponds to the value of the enumeration literal. Note that
976 -- this is normally the same as Enumeration_Pos except in the presence
977 -- of representation clauses, where Pos will still represent the
978 -- position of the literal within the type and Rep will have be the
979 -- value given in the representation clause.
981 -- Enumeration_Rep_Expr (Node22)
982 -- Present in enumeration literals. Points to the expression in an
983 -- associated enumeration rep clause that provides the representation
984 -- value for this literal. Empty if no enumeration rep clause for this
985 -- literal (or if rep clause does not have an entry for this literal,
986 -- an error situation). This is also used to catch duplicate entries
987 -- for the same literal.
989 -- Enum_Pos_To_Rep (Node23)
990 -- Present in enumeration types (but not enumeration subtypes). Set to
991 -- Empty unless the enumeration type has a non-standard representation
992 -- (i.e. at least one literal has a representation value different from
993 -- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
994 -- array constructed when the type is frozen that maps Pos values to
995 -- corresponding Rep values. The index type of this array is Natural,
996 -- and the component type is a suitable integer type that holds the
997 -- full range of representation values.
999 -- Equivalent_Type (Node18)
1000 -- Present in class wide types and subtypes, access to protected
1001 -- subprogram types, and in exception types. For a classwide type, it
1002 -- is always Empty. For a class wide subtype, it points to an entity
1003 -- created by the expander which gives Gigi an easily understandable
1004 -- equivalent of the class subtype with a known size (given by an
1005 -- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
1006 -- details. For E_Exception_Type, this points to the record containing
1007 -- the data necessary to represent exceptions (for further details, see
1008 -- System.Standard_Library. For access_to_protected subprograms, it
1009 -- denotes a record that holds pointers to the operation and to the
1010 -- protected object. For remote Access_To_Subprogram types, it denotes
1011 -- the record that is the fat pointer representation of an RAST.
1014 -- Present in all types and subtypes, and also for components, constants,
1015 -- and variables, including exceptions where it refers to the static data
1016 -- allocated for an exception. Contains the Object_Size of the type or of
1017 -- the object. A value of zero indicates that the value is not yet known.
1019 -- For the case of components where a component clause is present, the
1020 -- value is the value from the component clause, which must be non-
1021 -- negative (but may be zero, which is acceptable for the case of
1022 -- a type with only one possible value). It is also possible for Esize
1023 -- of a component to be set without a component clause present, which
1024 -- means that the component size is specified, but not the position.
1025 -- See also RM_Size and the section on "Handling of Type'Size Values".
1026 -- During gigi processing, the value is back annotated for all zero
1027 -- values, so that after the call to gigi, the value is properly set.
1030 -- Present in all entities. Represents the type of the entity, which
1031 -- is itself another entity. For a type entity, points to the parent
1032 -- type for a derived type, or if the type is not derived, points to
1033 -- itself. For a subtype entity, Etype points to the base type. For
1034 -- a class wide type, points to the parent type. For a subprogram or
1035 -- subprogram type, Etype has the return type of a function or is set
1036 -- to Standard_Void_Type to represent a procedure.
1038 -- Exception_Code (Uint22)
1039 -- Present in exception entitites. Set to zero unless either an
1040 -- Import_Exception or Export_Exception pragma applies to the
1041 -- pragma and specifies a Code value. See description of these
1042 -- pragmas for details. Note that this field is relevant only if
1043 -- Is_VMS_Exception is set.
1045 -- Extra_Formal (Node15)
1046 -- Present in formal parameters in the non-generic case. Certain
1047 -- parameters require extra implicit information to be passed (e.g. the
1048 -- flag indicating if an unconstrained variant record argument is
1049 -- constrained, and the accessibility level for access parameters. See
1050 -- description of Extra_Constrained, Extra_Accessibility fields for
1051 -- further details. Extra formal parameters are constructed to represent
1052 -- these values, and chained to the end of the list of formals using the
1053 -- Extra_Formal field (i.e. the Extra_Formal field of the last "real"
1054 -- formal points to the first extra formal, and the Extra_Formal field of
1055 -- each extra formal points to the next one, with Empty indicating the
1056 -- end of the list of extra formals.
1058 -- Extra_Formals (Node28)
1059 -- Applies to subprograms and subprogram types, and also in entries
1060 -- and entry families. Returns first extra formal of the subprogram
1061 -- or entry. Returns Empty if there are no extra formals.
1063 -- Extra_Accessibility (Node13)
1064 -- Present in formal parameters in the non-generic case if expansion is
1065 -- active. Normally Empty, but if a parameter is one for which a dynamic
1066 -- accessibility check is required, then an extra formal of type
1067 -- Natural is created (see description of field Extra_Formal), and the
1068 -- Extra_Accessibility field of the formal parameter points to the entity
1069 -- for this extra formal. Also present in variables when compiling
1070 -- receiving stubs. In this case, a non Empty value means that this
1071 -- variable's accessibility depth has been transmitted by the caller and
1072 -- must be retrieved through the entity designed by this field instead of
1075 -- Extra_Constrained (Node23)
1076 -- Present in formal parameters in the non-generic case if expansion is
1077 -- active. Normally Empty, but if a parameter is one for which a dynamic
1078 -- indication of its constrained status is required, then an extra formal
1079 -- of type Boolean is created (see description of field Extra_Formal),
1080 -- and the Extra_Constrained field of the formal parameter points to the
1081 -- entity for this extra formal. Also present in variables when compiling
1082 -- receiving stubs. In this case, a non empty value means that this
1083 -- variable's constrained status has been transmitted by the caller and
1084 -- must be retrieved through the entity designed by this field instead of
1087 -- Can_Use_Internal_Rep (Flag229) [base type only]
1088 -- Present in Access_Subprogram_Kind nodes. This flag is set by the
1089 -- front end and used by the back end. False means that the back end
1090 -- must represent the type in the same way as Convention-C types (and
1091 -- other foreign-convention types). On many targets, this means that
1092 -- the back end will use dynamically generated trampolines for nested
1093 -- subprograms. True means that the back end can represent the type in
1094 -- some internal way. On the aforementioned targets, this means that the
1095 -- back end will not use dynamically generated trampolines. This flag
1096 -- must be False if Has_Foreign_Convention is True; otherwise, the front
1097 -- end is free to set the policy.
1099 -- Setting this False in all cases corresponds to the traditional back
1100 -- end strategy, where all access-to-subprogram types are represented the
1101 -- same way, independent of the Convention. See also
1102 -- Always_Compatible_Rep in Targparm.
1104 -- Efficiency note: On targets that use dynamically generated
1105 -- trampolines, False generally favors efficiency of top-level
1106 -- subprograms, whereas True generally favors efficiency of nested
1107 -- ones. On other targets, this flag has little or no effect on
1108 -- efficiency. The front end should take this into account. In
1109 -- particular, pragma Favor_Top_Level gives a hint that the flag should
1112 -- Note: We considered using Convention-C for this purpose, but we need
1113 -- this separate flag, because Convention-C implies that for
1114 -- P'[Unrestricted_]Access, P also have convention C. Sometimes we want
1115 -- to have Can_Use_Internal_Rep False for an access type, but allow P to
1116 -- have convention Ada.
1118 -- Finalization_Chain_Entity (Node19)
1119 -- Present in scopes that can have finalizable entities (blocks,
1120 -- functions, procedures, tasks, entries, return statements). When this
1121 -- field is empty it means that there are no finalization actions to
1122 -- perform on exit of the scope. When this field contains 'Error', it
1123 -- means that no finalization actions should happen at this level and
1124 -- the finalization chain of a parent scope shall be used (??? this is
1125 -- an improper use of 'Error' and should be changed). Otherwise it
1126 -- contains an entity of type Finalizable_Ptr that is the head of the
1127 -- list of objects to finalize on exit. See "Finalization Management"
1128 -- section in exp_ch7.adb for more details.
1130 -- Finalize_Storage_Only (Flag158) [base type only]
1131 -- Present in all types. Set on direct controlled types to which a
1132 -- valid Finalize_Storage_Only pragma applies. This flag is also set on
1133 -- composite types when they have at least one controlled component and
1134 -- all their controlled components are Finalize_Storage_Only. It is also
1135 -- inherited by type derivation except for direct controlled types where
1136 -- the Finalize_Storage_Only pragma is required at each level of
1139 -- First_Component (synthesized)
1140 -- Applies to record types. Returns the first component by following the
1141 -- chain of declared entities for the record until a component is found
1142 -- (one with an Ekind of E_Component). The discriminants are skipped. If
1143 -- the record is null, then Empty is returned.
1145 -- First_Component_Or_Discriminant (synthesized)
1146 -- Similar to First_Component, but discriminants are not skipped, so will
1147 -- find the first discriminant if discriminants are present.
1149 -- First_Entity (Node17)
1150 -- Present in all entities which act as scopes to which a list of
1151 -- associated entities is attached (blocks, class subtypes and types,
1152 -- entries, functions, loops, packages, procedures, protected objects,
1153 -- record types and subtypes, private types, task types and subtypes).
1154 -- Points to a list of associated entities using the Next_Entity field
1155 -- as a chain pointer with Empty marking the end of the list.
1157 -- First_Exit_Statement (Node8)
1158 -- Present in E_Loop entity. The exit statements for a loop are chained
1159 -- (in reverse order of appearence) using this field to point to the
1160 -- first entry in the chain (last exit statement in the loop). The
1161 -- entries are chained through the Next_Exit_Statement field of the
1162 -- N_Exit_Statement node with Empty marking the end of the list.
1164 -- First_Formal (synthesized)
1165 -- Applies to subprograms and subprogram types, and also in entries
1166 -- and entry families. Returns first formal of the subprogram or entry.
1167 -- The formals are the first entities declared in a subprogram or in
1168 -- a subprogram type (the designated type of an Access_To_Subprogram
1169 -- definition) or in an entry.
1171 -- First_Formal_With_Extras (synthesized)
1172 -- Applies to subprograms and subprogram types, and also in entries
1173 -- and entry families. Returns first formal of the subprogram or entry.
1174 -- Returns Empty if there are no formals. The list returned includes
1175 -- all the extra formals (see description of Extra_Formals field).
1177 -- First_Index (Node17)
1178 -- Present in array types and subtypes and in string types and subtypes.
1179 -- By introducing implicit subtypes for the index constraints, we have
1180 -- the same structure for constrained and unconstrained arrays, subtype
1181 -- marks and discrete ranges are both represented by a subtype. This
1182 -- function returns the tree node corresponding to an occurrence of the
1183 -- first index (NOT the entity for the type). Subsequent indexes are
1184 -- obtained using Next_Index. Note that this field is present for the
1185 -- case of string literal subtypes, but is always Empty.
1187 -- First_Literal (Node17)
1188 -- Present in all enumeration types, including character and boolean
1189 -- types. This field points to the first enumeration literal entity
1190 -- for the type (i.e. it is set to First (Literals (N)) where N is
1191 -- the enumeration type definition node. A special case occurs with
1192 -- standard character and wide character types, where this field is
1193 -- Empty, since there are no enumeration literal lists in these cases.
1194 -- Note that this field is set in enumeration subtypes, but it still
1195 -- points to the first literal of the base type in this case.
1197 -- First_Optional_Parameter (Node14)
1198 -- Present in (non-generic) function and procedure entities. Set to a
1199 -- non-null value only if a pragma Import_Function, Import_Procedure
1200 -- or Import_Valued_Procedure specifies a First_Optional_Parameter
1201 -- argument, in which case this field points to the parameter entity
1202 -- corresponding to the specified parameter.
1204 -- First_Private_Entity (Node16)
1205 -- Present in all entities containing private parts (packages, protected
1206 -- types and subtypes, task types and subtypes). The entities on the
1207 -- entity chain are in order of declaration, so the entries for private
1208 -- entities are at the end of the chain. This field points to the first
1209 -- entity for the private part. It is Empty if there are no entities
1210 -- declared in the private part or if there is no private part.
1212 -- First_Rep_Item (Node6)
1213 -- Present in all entities. If non-empty, points to a linked list of
1214 -- representation pragmas nodes and representation clause nodes that
1215 -- apply to the entity, linked using Next_Rep_Item, with Empty marking
1216 -- the end of the list. In the case of derived types and subtypes, the
1217 -- new entity inherits the chain at the point of declaration. This
1218 -- means that it is possible to have multiple instances of the same
1219 -- kind of rep item on the chain, in which case it is the first one
1220 -- that applies to the entity.
1222 -- Note: pragmas that can apply to more than one overloadable entity,
1223 -- (Convention, Interface, Inline, Inline_Always, Import, Export,
1224 -- External) are never present on this chain when they apply to
1225 -- overloadable entities, since it is impossible for a given pragma
1226 -- to be on more than one chain at a time.
1228 -- For most representation items, the representation information is
1229 -- reflected in other fields and flags in the entity. For example if a
1230 -- record representation clause is present, the component entities
1231 -- reflect the specified information. However, there are some items that
1232 -- are only reflected in the chain. These include:
1234 -- Alignment attribute definition clause
1235 -- Machine_Attribute pragma
1236 -- Link_Alias pragma
1237 -- Link-Section pragma
1238 -- Weak_External pragma
1240 -- If any of these items are present, then the flag Has_Gigi_Rep_Item
1241 -- is set, indicating that Gigi should search the chain.
1243 -- Other representation items are included in the chain so that error
1244 -- messages can easily locate the relevant nodes for posting errors.
1245 -- Note in particular that size clauses are present only for this
1246 -- purpose, and should only be accessed if Has_Size_Clause is set.
1248 -- Freeze_Node (Node7)
1249 -- Present in all entities. If there is an associated freeze node for
1250 -- the entity, this field references this freeze node. If no freeze
1251 -- node is associated with the entity, then this field is Empty. See
1252 -- package Freeze for further details.
1254 -- From_With_Type (Flag159)
1255 -- Present in package and type entities. Indicates that the entity
1256 -- appears in a With_Type clause in the context of some other unit,
1257 -- either as the prefix (which must be a package), or as a type name.
1258 -- The package can only be used to retrieve such a type, and the type
1259 -- can be used only in component declarations and access definitions.
1260 -- The With_Type clause is used to construct mutually recursive
1261 -- types, i.e. record types (Java classes) that hold pointers to each
1262 -- other. If such a type is an access type, it has no explicit freeze
1263 -- node, so that the back-end does not attempt to elaborate it.
1264 -- Currently this flag is also used to implement Ada 2005 (AI-50217).
1265 -- It will be renamed to From_Limited_With after removal of the current
1266 -- GNAT with_type clause???
1268 -- Full_View (Node11)
1269 -- Present in all type and subtype entities and in deferred constants.
1270 -- References the entity for the corresponding full type declaration.
1271 -- For all types other than private and incomplete types, this field
1272 -- always contains Empty. See also Underlying_Type.
1274 -- Generic_Homonym (Node11)
1275 -- Present in generic packages. The generic homonym is the entity of
1276 -- a renaming declaration inserted in every generic unit. It is used
1277 -- to resolve the name of a local entity that is given by a qualified
1278 -- name, when the generic entity itself is hidden by a local name.
1280 -- Generic_Renamings (Elist23)
1281 -- Present in package and subprogram instances. Holds mapping that
1282 -- associates generic parameters with the corresponding instances, in
1283 -- those cases where the instance is an entity.
1285 -- Handler_Records (List10)
1286 -- Present in subprogram and package entities. Points to a list of
1287 -- identifiers referencing the handler record entities for the
1288 -- corresponding unit.
1290 -- Has_Aliased_Components (Flag135) [implementation base type only]
1291 -- Present in array type entities. Indicates that the component type
1292 -- of the array is aliased.
1294 -- Has_Alignment_Clause (Flag46)
1295 -- Present in all type entities and objects. Indicates if an alignment
1296 -- clause has been given for the entity. If set, then Alignment_Clause
1297 -- returns the N_Attribute_Definition node for the alignment attribute
1298 -- definition clause. Note that it is possible for this flag to be False
1299 -- even when Alignment_Clause returns non_Empty (this happens in the case
1300 -- of derived type declarations).
1302 -- Has_All_Calls_Remote (Flag79)
1303 -- Present in all library unit entities. Set true if the library unit
1304 -- has an All_Calls_Remote pragma. Note that such entities must also
1305 -- be RCI entities, so the flag Is_Remote_Call_Interface will always
1306 -- be set if this flag is set.
1308 -- Has_Anon_Block_Suffix (Flag201)
1309 -- Present in all entities. Set if the entity is nested within one or
1310 -- more anonymous blocks and the Chars field contains a name with an
1311 -- anonymous block suffix (see Exp_Dbug for furthert details).
1313 -- Has_Atomic_Components (Flag86) [implementation base type only]
1314 -- Present in all types and objects. Set only for an array type or
1315 -- an array object if a valid pragma Atomic_Components applies to the
1316 -- type or object. Note that in the case of an object, this flag is
1317 -- only set on the object if there was an explicit pragma for the
1318 -- object. In other words, the proper test for whether an object has
1319 -- atomic components is to see if either the object or its base type
1320 -- has this flag set. Note that in the case of a type, the pragma will
1321 -- be chained to the rep item chain of the first subtype in the usual
1324 -- Has_Attach_Handler (synthesized)
1325 -- Applies to record types that are constructed by the expander to
1326 -- represent protected types. Returns True if there is at least one
1327 -- Attach_Handler pragma in the corresponding specification.
1329 -- Has_Biased_Representation (Flag139)
1330 -- Present in discrete types (where it applies to the type'size value),
1331 -- and to objects (both stand-alone and components), where it applies to
1332 -- the size of the object from a size or record component clause. In
1333 -- all cases it indicates that the size in question is smaller than
1334 -- would normally be required, but that the size requirement can be
1335 -- satisfied by using a biased representation, in which stored values
1336 -- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
1337 -- reduce the required size. For example, a type with a range of 1..2
1338 -- takes one bit, using 0 to represent 1 and 1 to represent 2.
1340 -- Note that in the object and component cases, the flag is only set if
1341 -- the type is unbiased, but the object specifies a smaller size than the
1342 -- size of the type, forcing biased representation for the object, but
1343 -- the subtype is still an unbiased type.
1345 -- Has_Completion (Flag26)
1346 -- Present in all entities that require a completion (functions,
1347 -- procedures, private types, limited private types, incomplete types,
1348 -- constants and packages that require a body). The flag is set if the
1349 -- completion has been encountered and analyzed.
1351 -- Has_Completion_In_Body (Flag71)
1352 -- Present in all entities for types and subtypes. Set only in "Taft
1353 -- amendment types" (incomplete types whose full declaration appears in
1354 -- the package body).
1356 -- Has_Complex_Representation (Flag140) [implementation base type only]
1357 -- Present in all type entities. Set only for a record base type to
1358 -- which a valid pragma Complex_Representation applies.
1360 -- Has_Component_Size_Clause (Flag68) [implementation base type only]
1361 -- Present in all type entities. Set if a component size clause is
1362 -- present for the given type. Note that this flag can be False even
1363 -- if Component_Size is non-zero (happens in the case of derived types).
1365 -- Has_Constrained_Partial_View (Flag187)
1366 -- Present in private type and their completions, when the private
1367 -- type has no discriminants and the full view has discriminants with
1368 -- defaults. In Ada 2005 heap-allocated objects of such types are not
1369 -- constrained, and can change their discriminants with full assignment.
1371 -- Has_Contiguous_Rep (Flag181)
1372 -- Present in enumeration types. True if the type as a representation
1373 -- clause whose entries are successive integers.
1375 -- Has_Controlling_Result (Flag98)
1376 -- Present in E_Function entities. True if the function is a primitive
1377 -- function of a tagged type which can dispatch on result.
1379 -- Has_Controlled_Component (Flag43) [base type only]
1380 -- Present in all entities. Set only for composite type entities which
1381 -- contain a component that either is a controlled type, or itself
1382 -- contains controlled component (i.e. either Has_Controlled_Component
1383 -- or Is_Controlled is set for at least one component).
1385 -- Has_Convention_Pragma (Flag119)
1386 -- Present in all entities. Set true for an entity for which a valid
1387 -- Convention, Import, or Export pragma has been given. Used to prevent
1388 -- more than one such pragma appearing for a given entity (RM B.1(45)).
1390 -- Has_Delayed_Freeze (Flag18)
1391 -- Present in all entities. Set to indicate that an explicit freeze
1392 -- node must be generated for the entity at its freezing point. See
1393 -- separate section ("Delayed Freezing and Elaboration") for details.
1395 -- Has_Discriminants (Flag5)
1396 -- Present in all types and subtypes. For types that are allowed to have
1397 -- discriminants (record types and subtypes, task types and subtypes,
1398 -- protected types and subtypes, private types, limited private types,
1399 -- and incomplete types), indicates if the corresponding type or subtype
1400 -- has a known discriminant part. Always false for all other types.
1402 -- Has_Dispatch_Table (Flag220)
1403 -- Present in E_Record_Types that are tagged. Set to indicate that the
1404 -- corresponding dispatch table is already built. This flag is used to
1405 -- avoid duplicate construction of library level dispatch tables (because
1406 -- the declaration of library level objects cause premature construction
1407 -- of the table); otherwise the code that builds the table is added at
1408 -- the end of the list of declarations of the package.
1410 -- Has_Entries (synthesized)
1411 -- Applies to concurrent types. True if any entries are declared
1412 -- within the task or protected definition for the type.
1414 -- Has_Enumeration_Rep_Clause (Flag66)
1415 -- Present in enumeration types. Set if an enumeration representation
1416 -- clause has been given for this enumeration type. Used to prevent more
1417 -- than one enumeration representation clause for a given type. Note
1418 -- that this does not imply a representation with holes, since the rep
1419 -- clause may merely confirm the default 0..N representation.
1421 -- Has_External_Tag_Rep_Clause (Flag110)
1422 -- Present in tagged types. Set if an external_tag rep. clause has been
1423 -- given for this type. Use to avoid the generation of the default
1426 -- Has_Exit (Flag47)
1427 -- Present in loop entities. Set if the loop contains an exit statement.
1429 -- Has_Foreign_Convention (synthesized)
1430 -- Applies to all entities. Determines if the Convention for the
1431 -- entity is a foreign convention (i.e. is other than Convention_Ada,
1432 -- Convention_Intrinsic, Convention_Entry or Convention_Protected).
1434 -- Has_Forward_Instantiation (Flag175)
1435 -- Present in package entities. Set true for packages that contain
1436 -- instantiations of local generic entities, before the corresponding
1437 -- generic body has been seen. If a package has a forward instantiation,
1438 -- we cannot inline subprograms appearing in the same package because
1439 -- the placement requirements of the instance will conflict with the
1440 -- linear elaboration of front-end inlining.
1442 -- Has_Fully_Qualified_Name (Flag173)
1443 -- Present in all entities. Set True if the name in the Chars field has
1444 -- been replaced by the fully qualified name, as used for debug output.
1445 -- See Exp_Dbug for a full description of the use of this flag and also
1446 -- the related flag Has_Qualified_Name.
1448 -- Has_Gigi_Rep_Item (Flag82)
1449 -- Present in all entities. Set if the rep item chain (referenced by
1450 -- First_Rep_Item and linked through the Next_Rep_Item chain) contains a
1451 -- representation item that needs to be specially processed by Gigi, i.e.
1452 -- one of the following items:
1454 -- Machine_Attribute pragma
1455 -- Linker_Alias pragma
1456 -- Linker_Section pragma
1457 -- Linker_Constructor pragma
1458 -- Linker_Destructor pragma
1459 -- Weak_External pragma
1461 -- If this flag is set, then Gigi should scan the rep item chain to
1462 -- process any of these items that appear. At least one such item will
1465 -- Has_Homonym (Flag56)
1466 -- Present in all entities. Set if an entity has a homonym in the same
1467 -- scope. Used by Gigi to generate unique names for such entities.
1469 -- Has_Initial_Value (Flag219)
1470 -- Present in entities for variables and out parameters. Set if there
1471 -- is an explicit initial value expression in the declaration of the
1472 -- variable. Note that this is set only if this initial value is
1473 -- explicit, it is not set for the case of implicit initialization
1474 -- of access types or controlled types. Always set to False for out
1475 -- parameters. Also present in entities for in and in-out parameters,
1476 -- but always false in these cases.
1478 -- Has_Interrupt_Handler (synthesized)
1479 -- Applies to all protected type entities. Set if the protected type
1480 -- definition contains at least one procedure to which a pragma
1481 -- Interrupt_Handler applies.
1483 -- Has_Machine_Radix_Clause (Flag83)
1484 -- Present in decimal types and subtypes, set if a Machine_Radix
1485 -- representation clause is present. This flag is used to detect
1486 -- the error of multiple machine radix clauses for a single type.
1488 -- Has_Master_Entity (Flag21)
1489 -- Present in entities that can appear in the scope stack (see spec
1490 -- of Sem). It is set if a task master entity (_master) has been
1491 -- declared and initialized in the corresponding scope.
1493 -- Has_Missing_Return (Flag142)
1494 -- Present in functions and generic functions. Set if there is one or
1495 -- more missing return statements in the function. This is used to
1496 -- control wrapping of the body in Exp_Ch6 to ensure that the program
1497 -- error exeption is correctly raised in this case at runtime.
1499 -- Has_Up_Level_Access (Flag215)
1500 -- Present in E_Variable and E_Constant entities. Set if the entity
1501 -- is a local variable declared in a subprogram p and is accessed in
1502 -- a subprogram nested inside p. Currently this flag is only set when
1503 -- VM_Target /= No_VM, for efficiency, since only the .NET back-end
1504 -- makes use of it to generate proper code for up-level references.
1506 -- Has_Nested_Block_With_Handler (Flag101)
1507 -- Present in scope entities. Set if there is a nested block within the
1508 -- scope that has an exception handler and the two scopes are in the
1509 -- same procedure. This is used by the backend for controlling certain
1510 -- optimizations to ensure that they are consistent with exceptions.
1511 -- See documentation in Gigi for further details.
1513 -- Has_Non_Standard_Rep (Flag75) [implementation base type only]
1514 -- Present in all type entities. Set when some representation clause
1515 -- or pragma causes the representation of the item to be significantly
1516 -- modified. In this category are changes of small or radix for a
1517 -- fixed-point type, change of component size for an array, and record
1518 -- or enumeration representation clauses, as well as packed pragmas.
1519 -- All other representation clauses (e.g. Size and Alignment clauses)
1520 -- are not considered to be significant since they do not affect
1521 -- stored bit patterns.
1523 -- Has_Object_Size_Clause (Flag172)
1524 -- Present in entities for types and subtypes. Set if an Object_Size
1525 -- clause has been processed for the type Used to prevent multiple
1526 -- Object_Size clauses for a given entity.
1528 -- Has_Per_Object_Constraint (Flag154)
1529 -- Present in E_Component entities, true if the subtype of the
1530 -- component has a per object constraint. Per object constraints result
1531 -- from the following situations:
1533 -- 1. N_Attribute_Reference - when the prefix is the enclosing type and
1534 -- the attribute is Access.
1535 -- 2. N_Discriminant_Association - when the expression uses the
1536 -- discriminant of the enclosing type.
1537 -- 3. N_Index_Or_Discriminant_Constraint - when at least one of the
1538 -- individual constraints is a per object constraint.
1539 -- 4. N_Range - when the lower or upper bound uses the discriminant of
1540 -- the enclosing type.
1541 -- 5. N_Range_Constraint - when the range expression uses the
1542 -- discriminant of the enclosing type.
1544 -- Has_Persistent_BSS (Flag188)
1545 -- Present in all entities. Set True for entities to which a valid
1546 -- pragma Persistent_BSS applies. Note that although the pragma is
1547 -- only meaningful for objects, we set it for all entities in a unit
1548 -- to which the pragma applies, as well as the unit entity itself, for
1549 -- convenience in propagating the flag to contained entities.
1551 -- Has_Postconditions (Flag240)
1552 -- Present in subprogram entities. Set if postconditions are active for
1553 -- the procedure, and a _postconditions procedure has been generated.
1555 -- Has_Pragma_Controlled (Flag27) [implementation base type only]
1556 -- Present in access type entities. It is set if a pragma Controlled
1557 -- applies to the access type.
1559 -- Has_Pragma_Elaborate_Body (Flag150)
1560 -- Present in all entities. Set in compilation unit entities if a
1561 -- pragma Elaborate_Body applies to the compilation unit.
1563 -- Has_Pragma_Inline (Flag157)
1564 -- Present in all entities. Set for functions and procedures for which a
1565 -- pragma Inline or Inline_Always applies to the subprogram. Note that
1566 -- this flag can be set even if Is_Inlined is not set. This happens for
1567 -- pragma Inline (if Inline_Active is False). In other words, the flag
1568 -- Has_Pragma_Inline represents the formal semantic status, and is used
1569 -- for checking semantic correctness. The flag Is_Inlined indicates
1570 -- whether inlining is actually active for the entity.
1572 -- Has_Pragma_Inline_Always (Flag230)
1573 -- Present in all entities. Set for functions and procedures for which a
1574 -- pragma Inline_Always applies. Note that if this flag is set, the flag
1575 -- Has_Pragma_Inline is also set.
1577 -- Has_Pragma_Pack (Flag121) [implementation base type only]
1578 -- Present in all entities. If set, indicates that a valid pragma Pack
1579 -- was given for the type. Note that this flag is not inherited by
1580 -- derived type. See also the Is_Packed flag.
1582 -- Has_Pragma_Pure (Flag203)
1583 -- Present in all entities. If set, indicates that a valid pragma Pure
1584 -- was given for the entity. In some cases, we need to test whether
1585 -- Is_Pure was explicitly set using this pragma.
1587 -- Has_Pragma_Preelab_Init (Flag221)
1588 -- Present in type and subtype entities. If set indicates that a valid
1589 -- pragma Preelaborable_Initialization applies to the type.
1591 -- Has_Pragma_Pure_Function (Flag179)
1592 -- Present in all entities. If set, indicates that a valid pragma
1593 -- Pure_Function was given for the entity. In some cases, we need to
1594 -- know that Is_Pure was explicitly set using this pragma.
1596 -- Has_Pragma_Thread_Local_Storage (Flag169)
1597 -- Present in all entities. If set, indicates that a valid pragma
1598 -- Thread_Local_Storage was given for the entity.
1600 -- Has_Pragma_Unmodified (Flag233)
1601 -- Present in all entities. Can only be set for variables (E_Variable,
1602 -- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified
1603 -- applies to the variable, indicating that no warning should be given
1604 -- if the entity is never modified. Note that clients should generally
1605 -- not test this flag directly, but instead use function Has_Unmodified.
1607 -- Has_Pragma_Unreferenced (Flag180)
1608 -- Present in all entities. Set if a valid pragma Unreferenced applies
1609 -- to the entity, indicating that no warning should be given if the
1610 -- entity has no references, but a warning should be given if it is
1611 -- in fact referenced. For private types, this flag is set in both the
1612 -- private entity and full entity if the pragma applies to either. Note
1613 -- that clients should generally not test this flag directly, but instead
1614 -- use function Has_Unreferenced.
1616 -- Has_Pragma_Unreferenced_Objects (Flag212)
1617 -- Present in type and subtype entities. Set if a valid pragma
1618 -- Unreferenced_Objects applies to the type, indicating that no warning
1619 -- should be given for objects of such a type for being unreferenced
1620 -- (but unlike the case with pragma Unreferenced, it is ok to reference
1621 -- such an object and no warning is generated.
1623 -- Has_Primitive_Operations (Flag120) [base type only]
1624 -- Present in all type entities. Set if at least one primitive operation
1625 -- is defined for the type.
1627 -- Has_Private_Ancestor (synthesized)
1628 -- Applies to all type and subtype entities. Returns True if at least
1629 -- one ancestor is private, and otherwise False if there are no private
1632 -- Has_Private_Declaration (Flag155)
1633 -- Present in all entities. Returns True if it is the defining entity
1634 -- of a private type declaration or its corresponding full declaration.
1635 -- This flag is thus preserved when the full and the partial views are
1636 -- exchanged, to indicate if a full type declaration is a completion.
1637 -- Used for semantic checks in E.4 (18), and elsewhere.
1639 -- Has_Qualified_Name (Flag161)
1640 -- Present in all entities. Set True if the name in the Chars field
1641 -- has been replaced by its qualified name, as used for debug output.
1642 -- See Exp_Dbug for a full description of qualification requirements.
1643 -- For some entities, the name is the fully qualified name, but there
1644 -- are exceptions. In particular, for local variables in procedures,
1645 -- we do not include the procedure itself or higher scopes. See also
1646 -- the flag Has_Fully_Qualified_Name, which is set if the name does
1647 -- indeed include the fully qualified name.
1649 -- Has_RACW (Flag214)
1650 -- Present in package spec entities. Set if the spec contains the
1651 -- declaration of a remote access-to-classwide type.
1653 -- Has_Record_Rep_Clause (Flag65) [implementation base type only]
1654 -- Present in record types. Set if a record representation clause has
1655 -- been given for this record type. Used to prevent more than one such
1656 -- clause for a given record type. Note that this is initially cleared
1657 -- for a derived type, even though the representation is inherited. See
1658 -- also the flag Has_Specified_Layout.
1660 -- Has_Recursive_Call (Flag143)
1661 -- Present in procedures. Set if a direct parameterless recursive call
1662 -- is detected while analyzing the body. Used to activate some error
1663 -- checks for infinite recursion.
1665 -- Has_Size_Clause (Flag29)
1666 -- Present in entities for types and objects. Set if a size clause is
1667 -- present for the entity. Used to prevent multiple Size clauses for a
1668 -- given entity. Note that it is always initially cleared for a derived
1669 -- type, even though the Size for such a type is inherited from a Size
1670 -- clause given for the parent type.
1672 -- Has_Small_Clause (Flag67)
1673 -- Present in ordinary fixed point types (but not subtypes). Indicates
1674 -- that a small clause has been given for the entity. Used to prevent
1675 -- multiple Small clauses for a given entity. Note that it is always
1676 -- initially cleared for a derived type, even though the Small for such
1677 -- a type is inherited from a Small clause given for the parent type.
1679 -- Has_Specified_Layout (Flag100) [implementation base type only]
1680 -- Present in all type entities. Set for a record type or subtype if
1681 -- the record layout has been specified by a record representation
1682 -- clause. Note that this differs from the flag Has_Record_Rep_Clause
1683 -- in that it is inherited by a derived type. Has_Record_Rep_Clause is
1684 -- used to indicate that the type is mentioned explicitly in a record
1685 -- representation clause, and thus is not inherited by a derived type.
1686 -- This flag is always False for non-record types.
1688 -- Has_Specified_Stream_Input (Flag190)
1689 -- Has_Specified_Stream_Output (Flag191)
1690 -- Has_Specified_Stream_Read (Flag192)
1691 -- Has_Specified_Stream_Write (Flag193)
1692 -- Present in all type and subtype entities. Set for a given view if the
1693 -- corresponding stream-oriented attribute has been defined by an
1694 -- attribute definition clause. When such a clause occurs, a TSS is set
1695 -- on the underlying full view; the flags are used to track visibility of
1696 -- the attribute definition clause for partial or incomplete views.
1698 -- Has_Static_Discriminants (Flag211)
1699 -- Present in record subtypes constrained by discriminant values. Set if
1700 -- all the discriminant values have static values, meaning that in the
1701 -- case of a variant record, the component list can be trimmed down to
1702 -- include only the components corresponding to these discriminants.
1704 -- Has_Storage_Size_Clause (Flag23) [implementation base type only]
1705 -- Present in task types and access types. It is set if a Storage_Size
1706 -- clause is present for the type. Used to prevent multiple clauses for
1707 -- one type. Note that this flag is initially cleared for a derived type
1708 -- even though the Storage_Size for such a type is inherited from a
1709 -- Storage_Size clause given for the parent type. Note that in the case
1710 -- of access types, this flag is present only in the root type, since a
1711 -- storage size clause cannot be given to a derived type.
1713 -- Has_Stream_Size_Clause (Flag184)
1714 -- Present in all entities. It is set for types which have a Stream_Size
1715 -- clause attribute. Used to prevent multiple Stream_Size clauses for a
1716 -- given entity, and also whether it is necessary to check for a stream
1719 -- Has_Subprogram_Descriptor (Flag93)
1720 -- This flag is set on entities for which zero-cost exception subprogram
1721 -- descriptors can be generated (subprograms and library level package
1722 -- declarations and bodies). It indicates that a subprogram descriptor
1723 -- has been generated, and is used to suppress generation of multiple
1724 -- descriptors (e.g. when instantiating generic bodies).
1726 -- Has_Task (Flag30) [base type only]
1727 -- Present in all type entities. Set on task types themselves, and also
1728 -- (recursively) on any composite type which has a component for which
1729 -- Has_Task is set. The meaning is that an allocator or declaration of
1730 -- such an object must create the required tasks. Note: the flag is not
1731 -- set on access types, even if they designate an object that Has_Task.
1733 -- Has_Thunks (Flag228)
1734 -- Applies to E_Constant entities marked Is_Tag. True for secondary tag
1735 -- referencing a dispatch table whose contents are pointers to thunks.
1737 -- Has_Unchecked_Union (Flag123) [base type only]
1738 -- Present in all type entities. Set on unchecked unions themselves
1739 -- and (recursively) on any composite type which has a component for
1740 -- which Has_Unchecked_Union is set. The meaning is that a comparison
1741 -- operation for the type is not permitted. Note that the flag is not
1742 -- set on access types, even if they designate an object that has
1743 -- the flag Has_Unchecked_Union set.
1745 -- Has_Unknown_Discriminants (Flag72)
1746 -- Present in all entities. Set for types with unknown discriminants.
1747 -- Types can have unknown discriminants either from their declaration or
1748 -- through type derivation. The use of this flag exactly meets the spec
1749 -- in RM 3.7(26). Note that all class-wide types are considered to have
1750 -- unknown discriminants. Note that both Has_Discriminants and
1751 -- Has_Unknown_Discriminants may be true for a type. Class-wide types and
1752 -- their subtypes have unknown discriminants and can have declared ones
1753 -- as well. Private types declared with unknown discriminants may have a
1754 -- full view that has explicit discriminants, and both flag will be set
1755 -- on the partial view, to insure that discriminants are properly
1756 -- inherited in certain contexts.
1758 -- Has_Volatile_Components (Flag87) [implementation base type only]
1759 -- Present in all types and objects. Set only for an array type or array
1760 -- object if a valid pragma Volatile_Components or a valid pragma
1761 -- Atomic_Components applies to the type or object. Note that in the case
1762 -- of an object, this flag is only set on the object if there was an
1763 -- explicit pragma for the object. In other words, the proper test for
1764 -- whether an object has volatile components is to see if either the
1765 -- object or its base type has this flag set. Note that in the case of a
1766 -- type the pragma will be chained to the rep item chain of the first
1767 -- subtype in the usual manner.
1769 -- Has_Xref_Entry (Flag182)
1770 -- Present in all entities. Set if an entity has an entry in the Xref
1771 -- information generated in ali files. This is true for all source
1772 -- entities in the extended main source file. It is also true of entities
1773 -- in other packages that are referenced directly or indirectly from the
1774 -- main source file (indirect reference occurs when the main source file
1775 -- references an entity with a type reference. See package Lib.Xref for
1776 -- further details).
1778 -- Hiding_Loop_Variable (Node8)
1779 -- Present in variables. Set only if a variable of a discrete type is
1780 -- hidden by a loop variable in the same local scope, in which case
1781 -- the Hiding_Loop_Variable field of the hidden variable points to
1782 -- the E_Loop_Parameter entity doing the hiding. Used in processing
1783 -- warning messages if the hidden variable turns out to be unused
1784 -- or is referenced without being set.
1787 -- Present in all entities. Link for list of entities that have the
1788 -- same source name and that are declared in the same or enclosing
1789 -- scopes. Homonyms in the same scope are overloaded. Used for name
1790 -- resolution and for the generation of debugging information.
1792 -- Implementation_Base_Type (synthesized)
1793 -- Applies to all entities. For types, similar to Base_Type, but never
1794 -- returns a private type when applied to a non-private type. Instead in
1795 -- this case, it always returns the Underlying_Type of the base type, so
1796 -- that we still have a concrete type. For entities other than types,
1797 -- returns the entity unchanged.
1799 -- Implemented_By_Entry (Flag232)
1800 -- Applies to functions and procedures. Set if pragma Implemented_By_
1801 -- Entry is applied on the subprogram entity.
1803 -- Interfaces (Elist25)
1804 -- Present in record types and subtypes. List of abstract interfaces
1805 -- implemented by a tagged type that are not already implemented by the
1806 -- ancestors (Ada 2005: AI-251).
1808 -- Interface_Alias (Node25)
1809 -- Present in subprograms that cover a primitive operation of an abstract
1810 -- interface type. Can be set only if the Is_Hidden flag is also set,
1811 -- since such entities are always hidden. Points to its associated
1812 -- interface subprogram. It is used to register the subprogram in
1813 -- secondary dispatch table of the interface (Ada 2005: AI-251).
1815 -- In_Package_Body (Flag48)
1816 -- Present in package entities. Set on the entity that denotes the
1817 -- package (the defining occurrence of the package declaration) while
1818 -- analyzing and expanding the package body. Reset on completion of
1819 -- analysis/expansion.
1821 -- In_Private_Part (Flag45)
1822 -- Present in all entities. Can be set only in package entities and
1823 -- objects. For package entities, this flag is set to indicate that the
1824 -- private part of the package is being analyzed. The flag is reset at
1825 -- the end of the package declaration. For objects it indicates that the
1826 -- declaration of the object occurs in the private part of a package.
1828 -- Inner_Instances (Elist23)
1829 -- Present in generic units. Contains element list of units that are
1830 -- instantiated within the given generic. Used to diagnose circular
1833 -- Interface_Name (Node21)
1834 -- Present in exceptions, functions, procedures, variables, constants,
1835 -- and packages. Set to Empty unless an export, import, or interface
1836 -- name pragma has explicitly specified an external name, in which
1837 -- case it references an N_String_Literal node for the specified
1838 -- external name. In the case of exceptions, the field is set by
1839 -- Import_Exception/Export_Exception (which can be used in OpenVMS
1840 -- versions only). Note that if this field is Empty, and Is_Imported
1841 -- or Is_Exported is set, then the default interface name is the name
1842 -- of the entity, cased in a manner that is appropriate to the system
1843 -- in use. Note that Interface_Name is ignored if an address clause
1844 -- is present (since it is meaningless in this case).
1846 -- An additional special case usage of this field is in JGNAT for
1847 -- E_Component and E_Discriminant. JGNAT allows these entities to be
1848 -- imported by specifying pragma Import within a component's containing
1849 -- record definition. This supports interfacing to object fields defined
1850 -- within Java classes, and such pragmas are generated by the jvm2ada
1851 -- binding generator tool whenever it processes classes with public
1852 -- object fields. A pragma Import for a component can define the
1853 -- External_Name of the imported Java field (which is generally needed,
1854 -- because Java names are case sensitive).
1857 -- Present in packages and types. Set when analyzing a use clause for
1858 -- the corresponding entity. Reset at end of corresponding declarative
1859 -- part. The flag on a type is also used to determine the visibility of
1860 -- the primitive operators of the type.
1862 -- Is_Abstract_Subprogram (Flag19)
1863 -- Present in all subprograms and entries. Set for abstract subprograms.
1864 -- Always False for enumeration literals and entries. See also
1865 -- Requires_Overriding.
1867 -- Is_Abstract_Type (Flag146)
1868 -- Present in all types. Set for abstract types.
1870 -- Is_Access_Constant (Flag69)
1871 -- Present in access types and subtypes. Indicates that the keyword
1872 -- constant was present in the access type definition.
1874 -- Is_Access_Protected_Subprogram_Type (synthesized)
1875 -- Applies to all types, true for named and anonymous access to
1876 -- protected subprograms.
1878 -- Is_Access_Type (synthesized)
1879 -- Applies to all entities, true for access types and subtypes
1881 -- Is_Ada_2005_Only (Flag185)
1882 -- Present in all entities, true if a valid pragma Ada_05 applies to the
1883 -- entity which specifically names the entity, indicating that the entity
1884 -- is Ada 2005 only. Note that this flag is not set if the entity is part
1885 -- of a unit compiled with the normal no-argument form of pragma Ada_05.
1887 -- Is_Aliased (Flag15)
1888 -- Present in objects whose declarations carry the keyword aliased,
1889 -- and on record components that have the keyword.
1891 -- Is_AST_Entry (Flag132)
1892 -- Present in entry entities. Set if a valid pragma AST_Entry applies
1893 -- to the entry. This flag can only be set in OpenVMS versions of GNAT.
1894 -- Note: we also allow the flag to appear in entry families, but given
1895 -- the current implementation of the pragma AST_Entry, this flag will
1896 -- always be False in entry families.
1898 -- Is_Atomic (Flag85)
1899 -- Present in all type entities, and also in constants, components and
1900 -- variables. Set if a pragma Atomic or Shared applies to the entity.
1901 -- In the case of private and incomplete types, this flag is set in
1902 -- both the partial view and the full view.
1904 -- Is_Array_Type (synthesized)
1905 -- Applies to all entities, true for array types and subtypes
1907 -- Is_Asynchronous (Flag81)
1908 -- Present in all type entities and in procedure entities. Set
1909 -- if a pragma Asynchronous applies to the entity.
1911 -- Is_Bit_Packed_Array (Flag122) [implementation base type only]
1912 -- Present in all entities. This flag is set for a packed array type that
1913 -- is bit packed (i.e. the component size is known by the front end and
1914 -- is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed is always set
1915 -- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be
1916 -- set without Is_Bit_Packed_Array for the case of an array having one or
1917 -- more index types that are enumeration types with non-standard
1918 -- enumeration representations.
1920 -- Is_Boolean_Type (synthesized)
1921 -- Applies to all entities, true for boolean types and subtypes,
1922 -- i.e. Standard.Boolean and all types ultimately derived from it.
1924 -- Is_Called (Flag102)
1925 -- Present in subprograms. Returns true if the subprogram is called
1926 -- in the unit being compiled or in a unit in the context. Used for
1929 -- Is_Character_Type (Flag63)
1930 -- Present in all entities. Set for character types and subtypes,
1931 -- i.e. enumeration types that have at least one character literal.
1933 -- Is_Child_Unit (Flag73)
1934 -- Present in all entities. Set only for defining entities of program
1935 -- units that are child units (but False for subunits).
1937 -- Is_Class_Wide_Type (synthesized)
1938 -- Applies to all entities, true for class wide types and subtypes
1940 -- Is_Class_Wide_Equivalent_Type (Flag35)
1941 -- Present in record types and subtypes. Set to True, if the type acts
1942 -- as a class-wide equivalent type, i.e. the Equivalent_Type field of
1943 -- some class-wide subtype entity references this record type.
1945 -- Is_Compilation_Unit (Flag149)
1946 -- Present in all entities. Set if the entity is a package or subprogram
1947 -- entity for a compilation unit other than a subunit (since we treat
1948 -- subunits as part of the same compilation operation as the ultimate
1949 -- parent, we do not consider them to be separate units for this flag).
1951 -- Is_Completely_Hidden (Flag103)
1952 -- Present in all entities. This flag can be set only for E_Discriminant
1953 -- entities. This flag can be set only for girder discriminants of
1954 -- untagged types. When set, the entity is a girder discriminant of a
1955 -- derived untagged type which is not directly visible in the derived
1956 -- type because the derived type or one of its ancestors have renamed the
1957 -- discriminants in the root type. Note: there are girder discriminants
1958 -- which are not Completely_Hidden (e.g. discriminants of a root type).
1960 -- Is_Composite_Type (synthesized)
1961 -- Applies to all entities, true for all composite types and
1962 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
1963 -- not both) is true of any type.
1965 -- Is_Concurrent_Record_Type (Flag20)
1966 -- Present in record types and subtypes. Set if the type was created
1967 -- by the expander to represent a task or protected type. For every
1968 -- concurrent type, such as record type is constructed, and task and
1969 -- protected objects are instances of this record type at runtime
1970 -- (Gigi will replace declarations of the concurrent type using the
1971 -- declarations of the corresponding record type). See package Exp_Ch9
1972 -- for further details.
1974 -- Is_Concurrent_Type (synthesized)
1975 -- Applies to all entities, true for task types and subtypes and for
1976 -- protected types and subtypes.
1978 -- Is_Constant_Object (synthesized)
1979 -- Applies to all entities, true for E_Constant, E_Loop_Parameter, and
1980 -- E_In_Parameter entities.
1982 -- Is_Constrained (Flag12)
1983 -- Present in types or subtypes which may have index, discriminant
1984 -- or range constraint (i.e. array types and subtypes, record types
1985 -- and subtypes, string types and subtypes, and all numeric types).
1986 -- Set if the type or subtype is constrained.
1988 -- Is_Constr_Subt_For_U_Nominal (Flag80)
1989 -- Present in all types and subtypes. Set true only for the constructed
1990 -- subtype of an object whose nominal subtype is unconstrained. Note
1991 -- that the constructed subtype itself will be constrained.
1993 -- Is_Constr_Subt_For_UN_Aliased (Flag141)
1994 -- Present in all types and subtypes. This flag can be set only if
1995 -- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in
1996 -- addition the object concerned is aliased. This flag is used by
1997 -- Gigi to determine whether a template must be constructed.
1999 -- Is_Constructor (Flag76)
2000 -- Present in function and procedure entities. Set if a pragma
2001 -- CPP_Constructor applies to the subprogram.
2003 -- Is_Controlled (Flag42) [base type only]
2004 -- Present in all type entities. Indicates that the type is controlled,
2005 -- i.e. is either a descendant of Ada.Finalization.Controlled or of
2006 -- Ada.Finalization.Limited_Controlled.
2008 -- Is_Controlling_Formal (Flag97)
2009 -- Present in all Formal_Kind entities. Marks the controlling parameters
2010 -- of dispatching operations.
2012 -- Is_CPP_Class (Flag74)
2013 -- Present in all type entities, set only for tagged types to which a
2014 -- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied.
2016 -- Is_Decimal_Fixed_Point_Type (synthesized)
2017 -- Applies to all type entities, true for decimal fixed point
2018 -- types and subtypes.
2020 -- Is_Descendent_Of_Address (Flag223)
2021 -- Present in all type and subtype entities. Indicates that a type is an
2022 -- address type that is visibly a numeric type. Used for semantic checks
2023 -- on VMS to remove ambiguities in universal integer expressions that may
2024 -- have an address interpretation
2026 -- Is_Discrete_Type (synthesized)
2027 -- Applies to all entities, true for all discrete types and subtypes
2029 -- Is_Discrete__Or_Fixed_Point_Type (synthesized)
2030 -- Applies to all entities, true for all discrete types and subtypes
2031 -- and all fixed-point types and subtypes.
2033 -- Is_Discrim_SO_Function (Flag176)
2034 -- Present in all entities. Set only in E_Function entities that Layout
2035 -- creates to compute discriminant-dependent dynamic size/offset values.
2037 -- Is_Discriminal (synthesized)
2038 -- Applies to all entities, true for renamings of discriminants. Such
2039 -- entities appear as constants or in parameters.
2041 -- Is_Dispatch_Table_Entity (Flag234)
2042 -- Applies to all entities. Set to indicate to the backend that this
2043 -- entity is associated with a dispatch table.
2045 -- Is_Dispatching_Operation (Flag6)
2046 -- Present in all entities. Set true for procedures, functions,
2047 -- generic procedures and generic functions if the corresponding
2048 -- operation is dispatching.
2050 -- Is_Dynamic_Scope (synthesized)
2051 -- Applies to all Entities. Returns True if the entity is a dynamic
2052 -- scope (i.e. a block, subprogram, task_type, entry
2053 -- or extended return statement).
2055 -- Is_Elementary_Type (synthesized)
2056 -- Applies to all entities, true for all elementary types and
2057 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
2058 -- not both) is true of any type.
2060 -- Is_Eliminated (Flag124)
2061 -- Present in type entities, subprogram entities, and object entities.
2062 -- Indicates that the corresponding entity has been eliminated by use
2063 -- of pragma Eliminate. Also used to mark subprogram entities whose
2064 -- declaration and body are within unreachable code that is removed.
2066 -- Is_Enumeration_Type (synthesized)
2067 -- Present in all entities, true for enumeration types and subtypes
2069 -- Is_Entry (synthesized)
2070 -- Applies to all entities, True only for entry and entry family
2071 -- entities and False for all other entity kinds.
2073 -- Is_Entry_Formal (Flag52)
2074 -- Present in all entities. Set only for entry formals (which can
2075 -- only be in, in-out or out parameters). This flag is used to speed
2076 -- up the test for the need to replace references in Exp_Ch2.
2078 -- Is_Exported (Flag99)
2079 -- Present in all entities. Set if the entity is exported. For now we
2080 -- only allow the export of constants, exceptions, functions, procedures
2081 -- and variables, but that may well change later on. Exceptions can only
2082 -- be exported in the OpenVMS and Java VM implementations of GNAT.
2084 -- Is_First_Subtype (Flag70)
2085 -- Present in all entities. True for first subtypes (RM 3.2.1(6)),
2086 -- i.e. the entity in the type declaration that introduced the type.
2087 -- This may be the base type itself (e.g. for record declarations and
2088 -- enumeration type declarations), or it may be the first subtype of
2089 -- an anonymous base type (e.g. for integer type declarations or
2090 -- constrained array declarations).
2092 -- Is_Fixed_Point_Type (synthesized)
2093 -- Applies to all entities, true for decimal and ordinary fixed
2094 -- point types and subtypes
2096 -- Is_Floating_Point_Type (synthesized)
2097 -- Applies to all entities, true for float types and subtypes
2099 -- Is_Formal (synthesized)
2100 -- Applies to all entities, true for IN, IN OUT and OUT parameters
2102 -- Is_Formal_Object (synthesized)
2103 -- Applies to all entities, true for generic IN and IN OUT parameters
2105 -- Is_Formal_Subprogram (Flag111)
2106 -- Present in all entities. Set for generic formal subprograms.
2108 -- Is_For_Access_Subtype (Flag118)
2109 -- Present in E_Private_Subtype and E_Record_Subtype entities. Means the
2110 -- sole purpose of the type is to be designated by an Access_Subtype and
2111 -- hence should not be expanded into components because the type may not
2112 -- have been found or frozen yet.
2114 -- Is_Frozen (Flag4)
2115 -- Present in all type and subtype entities. Set if type or subtype has
2118 -- Is_Generic_Actual_Type (Flag94)
2119 -- Present in all type and subtype entities. Set in the subtype
2120 -- declaration that renames the generic formal as a subtype of the
2121 -- actual. Guarantees that the subtype is not static within the instance.
2123 -- Is_Generic_Instance (Flag130)
2124 -- Present in all entities. Set to indicate that the entity is an
2125 -- instance of a generic unit, or a formal package (which is an instance
2126 -- of the template).
2128 -- Is_Generic_Subprogram (synthesized)
2129 -- Applies to all entities. Yields True for a generic subprogram
2130 -- (generic function, generic subprogram), False for all other entities.
2132 -- Is_Generic_Type (Flag13)
2133 -- Present in all entities. Set for types which are generic formal types.
2134 -- Such types have an Ekind that corresponds to their classification, so
2135 -- the Ekind cannot be used to identify generic types.
2137 -- Is_Generic_Unit (synthesized)
2138 -- Applies to all entities. Yields True for a generic unit (generic
2139 -- package, generic function, generic procedure), and False for all
2142 -- Is_Hidden (Flag57)
2143 -- Present in all entities. Set true for all entities declared in the
2144 -- private part or body of a package. Also marks generic formals of a
2145 -- formal package declared without a box. For library level entities,
2146 -- this flag is set if the entity is not publicly visible. This flag
2147 -- is reset when compiling the body of the package where the entity
2148 -- is declared, when compiling the private part or body of a public
2149 -- child unit, and when compiling a private child unit (see Install_
2150 -- Private_Declaration in sem_ch7).
2152 -- Is_Hidden_Open_Scope (Flag171)
2153 -- Present in all entities. Set true for a scope that contains the
2154 -- instantiation of a child unit, and whose entities are not visible
2155 -- during analysis of the instance.
2157 -- Is_Immediately_Visible (Flag7)
2158 -- Present in all entities. Set if entity is immediately visible, i.e.
2159 -- is defined in some currently open scope (RM 8.3(4)).
2161 -- Is_Imported (Flag24)
2162 -- Present in all entities. Set if the entity is imported. For now we
2163 -- only allow the import of exceptions, functions, procedures, packages.
2164 -- and variables. Exceptions can only be imported in the OpenVMS and
2165 -- Java VM implementations of GNAT. Packages and types can only be
2166 -- imported in the Java VM implementation.
2168 -- Is_Incomplete_Or_Private_Type (synthesized)
2169 -- Applies to all entities, true for private and incomplete types
2171 -- Is_Incomplete_Type (synthesized)
2172 -- Applies to all entities, true for incomplete types and subtypes
2174 -- Is_Inlined (Flag11)
2175 -- Present in all entities. Set for functions and procedures which are
2176 -- to be inlined. For subprograms created during expansion, this flag
2177 -- may be set directly by the expander to request inlining. Also set
2178 -- for packages that contain inlined subprograms, whose bodies must be
2179 -- be compiled. Is_Inlined is also set on generic subprograms and is
2180 -- inherited by their instances. It is also set on the body entities
2181 -- of inlined subprograms. See also Has_Pragma_Inline.
2183 -- Is_Instantiated (Flag126)
2184 -- Present in generic packages and generic subprograms. Set if the unit
2185 -- is instantiated from somewhere in the extended main source unit. This
2186 -- flag is used to control warnings about the unit being uninstantiated.
2187 -- Also set in a package that is used as an actual for a generic package
2188 -- formal in an instantiation. Also set on a parent instance, in the
2189 -- instantiation of a child, which is implicitly declared in the parent.
2191 -- Is_Integer_Type (synthesized)
2192 -- Applies to all entities, true for integer types and subtypes
2194 -- Is_Interface (Flag186)
2195 -- Present in record types and subtypes. Set to indicate that the current
2196 -- entity corresponds with an abstract interface. Because abstract
2197 -- interfaces are conceptually a special kind of abstract tagged types
2198 -- we represent them by means of tagged record types and subtypes
2199 -- marked with this attribute. This allows us to reuse most of the
2200 -- compiler support for abstract tagged types to implement interfaces
2201 -- (Ada 2005: AI-251).
2203 -- Is_Internal (Flag17)
2204 -- Present in all entities. Set to indicate an entity created during
2205 -- semantic processing (e.g. an implicit type, or a temporary). The
2206 -- current uses of this flag are:
2208 -- 1) Internal entities (such as temporaries generated for the result
2209 -- of an inlined function call or dummy variables generated for the
2210 -- debugger). Set to indicate that they need not be initialized, even
2211 -- when scalars are initialized or normalized;
2213 -- 2) Predefined primitives of tagged types. Set to mark that they
2214 -- have specific properties: first they are primitives even if they
2215 -- are not defined in the type scope (the freezing point is not
2216 -- necessarily in the same scope), and second the predefined equality
2217 -- can be overridden by a user-defined equality, no body will be
2218 -- generated in this case.
2220 -- 3) Object declarations generated by the expander that are implicitly
2221 -- imported or exported so that they can be marked in Sprint output.
2223 -- 4) Internal entities in the list of primitives of tagged types that
2224 -- are used to handle secondary dispatch tables. These entities have
2225 -- also the attribute Interface_Alias.
2227 -- Is_Interrupt_Handler (Flag89)
2228 -- Present in procedures. Set if a pragma Interrupt_Handler applies
2229 -- to the procedure. The procedure must be parameterless, and on all
2230 -- targets except AAMP it must be a protected procedure.
2232 -- Is_Intrinsic_Subprogram (Flag64)
2233 -- Present in functions and procedures. It is set if a valid pragma
2234 -- Interface or Import is present for this subprogram specifying pragma
2235 -- Intrinsic. Valid means that the name and profile of the subprogram
2236 -- match the requirements of one of the recognized intrinsic subprograms
2237 -- (see package Sem_Intr for details). Note: the value of Convention for
2238 -- such an entity will be set to Convention_Intrinsic, but it is the
2239 -- setting of Is_Intrinsic_Subprogram, NOT simply having convention set
2240 -- to intrinsic, which causes intrinsic code to be generated.
2242 -- Is_Itype (Flag91)
2243 -- Present in all entities. Set to indicate that a type is an Itype,
2244 -- which means that the declaration for the type does not appear
2245 -- explicitly in the tree. Instead gigi will elaborate the type when it
2246 -- is first used. Has_Delayed_Freeze can be set for Itypes, and the
2247 -- meaning is that the first use (the one which causes the type to be
2248 -- defined) will be the freeze node. Note that an important restriction
2249 -- on Itypes is that the first use of such a type (the one that causes it
2250 -- to be defined) must be in the same scope as the type.
2252 -- Is_Known_Non_Null (Flag37)
2253 -- Present in all entities. Relevant (and can be set True) only for
2254 -- objects of an access type. It is set if the object is currently
2255 -- known to have a non-null value (meaning that no access checks
2256 -- are needed). The indication can for example come from assignment
2257 -- of an access parameter or an allocator whose value is known non-null.
2259 -- Note: this flag is set according to the sequential flow of the
2260 -- program, watching the current value of the variable. However,
2261 -- this processing can miss cases of changing the value of an aliased
2262 -- or constant object, so even if this flag is set, it should not
2263 -- be believed if the variable is aliased or volatile. It would
2264 -- be a little neater to avoid the flag being set in the first
2265 -- place in such cases, but that's trickier, and there is only
2266 -- one place that tests the value anyway.
2268 -- The flag is dynamically set and reset as semantic analysis and
2269 -- expansion proceeds. Its value is meaningless once the tree is
2270 -- fully constructed, since it simply indicates the last state.
2271 -- Thus this flag has no meaning to the back end.
2273 -- Is_Known_Null (Flag204)
2274 -- Present in all entities. Relevant (and can be set True) only for
2275 -- objects of an access type. It is set if the object is currently known
2276 -- to have a null value (meaning that a dereference will surely raise
2277 -- constraint error exception). The indication can come from an
2278 -- assignment or object declaration.
2280 -- The comments above about sequential flow and aliased and volatile for
2281 -- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag.
2283 -- Is_Known_Valid (Flag170)
2284 -- Present in all entities. Relevant for types (and subtype) and
2285 -- for objects (and enumeration literals) of a discrete type.
2287 -- The purpose of this flag is to implement the requirement stated
2288 -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
2289 -- values may not cause programs to become erroneous. See the function
2290 -- Checks.Expr_Known_Valid for further details. Note that the setting
2291 -- is conservative, in the sense that if the flag is set, it must be
2292 -- right. If the flag is not set, nothing is known about the validity.
2294 -- For enumeration literals, the flag is always set, since clearly
2295 -- an enumeration literal represents a valid value. Range checks
2296 -- where necessary will ensure that this valid value is appropriate.
2298 -- For objects, the flag indicates the state of knowledge about the
2299 -- current value of the object. This may be modified during expansion,
2300 -- and thus the final value is not relevant to gigi.
2302 -- For types and subtypes, the flag is set if all possible bit patterns
2303 -- of length Object_Size (i.e. Esize of the type) represent valid values
2304 -- of the type. In general for such tytpes, all values are valid, the
2305 -- only exception being the case where an object of the type has an
2306 -- explicit size that is greater than Object_Size.
2308 -- For non-discrete objects, the setting of the Is_Known_Valid flag is
2309 -- not defined, and is not relevant, since the considerations of the
2310 -- requirement in (RM 13.9.1(9-11)) do not apply.
2312 -- The flag is dynamically set and reset as semantic analysis and
2313 -- expansion proceeds. Its value is meaningless once the tree is
2314 -- fully constructed, since it simply indicates the last state.
2315 -- Thus this flag has no meaning to the back end.
2317 -- Is_Limited_Composite (Flag106)
2318 -- Present in all entities. Set for composite types that have a
2319 -- limited component. Used to enforce the rule that operations on
2320 -- the composite type that depend on the full view of the component
2321 -- do not become visible until the immediate scope of the composite
2322 -- type itself (RM 7.3.1 (5)).
2324 -- Is_Limited_Interface (Flag197)
2325 -- Present in record types and subtypes. True for interface types, if
2326 -- interface is declared limited, task, protected, or synchronized, or
2327 -- is derived from a limited interface.
2329 -- Is_Limited_Record (Flag25)
2330 -- Present in all entities. Set to true for record (sub)types if the
2331 -- record is declared to be limited. Note that this flag is not set
2332 -- simply because some components of the record are limited.
2334 -- Is_Local_Anonymous_Access (Flag194)
2335 -- Present in access types. Set for an anonymous access type to indicate
2336 -- that the type is created for a record component with an access
2337 -- definition, an array component, or a stand-alone object. Such
2338 -- anonymous types have an accessibility level equal to that of the
2339 -- declaration in which they appear, unlike the anonymous access types
2340 -- that are created for access parameters and access discriminants.
2342 -- Is_Machine_Code_Subprogram (Flag137)
2343 -- Present in subprogram entities. Set to indicate that the subprogram
2344 -- is a machine code subprogram (i.e. its body includes at least one
2345 -- code statement). Also indicates that all necessary semantic checks
2346 -- as required by RM 13.8(3) have been performed.
2348 -- Is_Modular_Integer_Type (synthesized)
2349 -- Applies to all entities. True if entity is a modular integer type
2351 -- Is_Non_Static_Subtype (Flag109)
2352 -- Present in all type and subtype entities. It is set in some (but not
2353 -- all) cases in which a subtype is known to be non-static. Before this
2354 -- flag was added, the computation of whether a subtype was static was
2355 -- entirely synthesized, by looking at the bounds, and the immediate
2356 -- subtype parent. However, this method does not work for some Itypes
2357 -- that have no parent set (and the only way to find the immediate
2358 -- subtype parent is to go through the tree). For now, this flay is set
2359 -- conservatively, i.e. if it is set then for sure the subtype is non-
2360 -- static, but if it is not set, then the type may or may not be static.
2361 -- Thus the test for a static subtype is that this flag is clear AND that
2362 -- the bounds are static AND that the parent subtype (if available to be
2363 -- tested) is static. Eventually we should make sure this flag is always
2364 -- set right, at which point, these comments can be removed, and the
2365 -- tests for static subtypes greatly simplified.
2367 -- Is_Null_Init_Proc (Flag178)
2368 -- Present in procedure entities. Set for generated init proc procedures
2369 -- (used to initialize composite types), if the code for the procedure
2370 -- is null (i.e. is a return and nothing else). Such null initialization
2371 -- procedures are generated in case some client is compiled using the
2372 -- Initialize_Scalars pragma, generating a call to this null procedure,
2373 -- but there is no need to call such procedures within a compilation
2374 -- unit, and this flag is used to suppress such calls.
2376 -- Is_Numeric_Type (synthesized)
2377 -- Applies to all entities, true for all numeric types and subtypes
2378 -- (integer, fixed, float).
2380 -- Is_Object (synthesized)
2381 -- Applies to all entities, true for entities representing objects,
2382 -- including generic formal parameters.
2384 -- Is_Obsolescent (Flag153)
2385 -- Present in all entities. Set for any entity for which a valid pragma
2386 -- Obsolescent applies.
2388 -- Is_Only_Out_Parameter (Flag226)
2389 -- Present in formal parameter entities. Set if this parameter is the
2390 -- only OUT parameter for this formal part. If there is more than one
2391 -- out parameter, or if there is some other IN OUT parameter then this
2392 -- flag is not set in any of them. Used in generation of warnings.
2394 -- Is_Optional_Parameter (Flag134)
2395 -- Present in parameter entities. Set if the parameter is specified as
2396 -- optional by use of a First_Optional_Parameter argument to one of the
2397 -- extended Import pragmas. Can only be set for OpenVMS versions of GNAT.
2399 -- Is_Ordinary_Fixed_Point_Type (synthesized)
2400 -- Applies to all entities, true for ordinary fixed point types and
2403 -- Is_Overriding_Operation (Flag39)
2404 -- Present in subprograms. Set if the subprogram is a primitive
2405 -- operation of a derived type, that overrides an inherited operation.
2407 -- Is_Package_Or_Generic_Package (synthesized)
2408 -- Applies to all entities. True for packages and generic packages.
2409 -- False for all other entities.
2411 -- Is_Package_Body_Entity (Flag160)
2412 -- Present in all entities. Set for entities defined at the top level
2413 -- of a package body. Used to control externally generated names.
2415 -- Is_Packed (Flag51) [implementation base type only]
2416 -- Present in all type entities. This flag is set only for record and
2417 -- array types which have a packed representation. There are three
2418 -- cases which cause packing:
2420 -- 1. Explicit use of pragma Pack for an array of package components
2421 -- 2. Explicit use of pragma Pack to pack a record
2422 -- 4. Setting Component_Size of an array to a bit-packable value
2423 -- 3. Indexing an array with a non-standard enumeration type.
2425 -- For records, Is_Packed is always set if Has_Pack_Pragma is set,
2426 -- and can also be set on its own in a derived type which inherited
2427 -- its packed status.
2429 -- For arrays, Is_Packed is set if an array is bit packed (i.e. the
2430 -- component size is known at compile time and is 1-7, 9-15 or 17-31),
2431 -- or if the array has one or more index types that are enumeration
2432 -- types with non-standard representations (in GNAT, we store such
2433 -- arrays compactly, using the Pos of the enumeration type value).
2435 -- As for the case of records, Is_Packed can be set on its own for a
2436 -- derived type, with the same dual before/after freeze meaning.
2437 -- Is_Packed can also be set as the result of an explicit component
2438 -- size clause that specifies an appropriate component size.
2440 -- In the bit packed array case, Is_Bit_Packed_Array will be set in
2441 -- the bit packed case once the array type is frozen.
2443 -- Before an array type is frozen, Is_Packed will always be set if
2444 -- Has_Pack_Pragma is set. Before the freeze point, it is not possible
2445 -- to know the component size, since the component type is not frozen
2446 -- until the array type is frozen. Thus Is_Packed for an array type
2447 -- before it is frozen means that packed is required. Then if it turns
2448 -- out that the component size is not suitable for bit packing, the
2449 -- Is_Packed flag gets turned off.
2451 -- Is_Packed_Array_Type (Flag138)
2452 -- Present in all entities. This flag is set on the entity for the type
2453 -- used to implement a packed array (either a modular type, or a subtype
2454 -- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
2455 -- if the type appears in the Packed_Array_Type field of some other type
2456 -- entity. It is used by Gigi to activate the special processing for such
2457 -- types (unchecked conversions that would not otherwise be allowed are
2458 -- allowed for such types). If the Is_Packed_Array_Type flag is set in
2459 -- an entity, then the Original_Array_Type field of this entity points
2460 -- to the original array type for which this is the packed array type.
2462 -- Is_Potentially_Use_Visible (Flag9)
2463 -- Present in all entities. Set if entity is potentially use visible,
2464 -- i.e. it is defined in a package that appears in a currently active
2465 -- use clause (RM 8.4(8)). Note that potentially use visible entities
2466 -- are not necessarily use visible (RM 8.4(9-11)).
2468 -- Is_Preelaborated (Flag59)
2469 -- Present in all entities, set in E_Package and E_Generic_Package
2470 -- entities to which a pragma Preelaborate is applied, and also in
2471 -- all entities within such packages. Note that the fact that this
2472 -- flag is set does not necesarily mean that no elaboration code is
2473 -- generated for the package.
2475 -- Is_Primitive (Flag218)
2476 -- Present in overloadable entities and in generic subprograms. Set to
2477 -- indicate that this is a primitive operation of some type, which may
2478 -- be a tagged type or a non-tagged type. Used to verify overriding
2479 -- indicators in bodies.
2481 -- Is_Primitive_Wrapper (Flag195)
2482 -- Present in functions and procedures created by the expander to serve
2483 -- as an indirection mechanism to overriding primitives of concurrent
2484 -- types, entries and protected procedures.
2486 -- Is_Prival (synthesized)
2487 -- Applies to all entities, true for renamings of private protected
2488 -- components. Such entities appear as constants or variables.
2490 -- Is_Private_Composite (Flag107)
2491 -- Present in composite types that have a private component. Used to
2492 -- enforce the rule that operations on the composite type that depend
2493 -- on the full view of the component, do not become visible until the
2494 -- immediate scope of the composite type itself (7.3.1 (5)). Both this
2495 -- flag and Is_Limited_Composite are needed.
2497 -- Is_Private_Descendant (Flag53)
2498 -- Present in entities that can represent library units (packages,
2499 -- functions, procedures). Set if the library unit is itself a private
2500 -- child unit, or if it is the descendent of a private child unit.
2502 -- Is_Private_Primitive (Flag245)
2503 -- Present in subprograms. Set if the operation is a primitive of a
2504 -- tagged type (procedure or function dispatching on result) whose
2505 -- full view has not been seen. Used in particular for primitive
2506 -- subprograms of a synchronized type declared between the two views
2507 -- of the type, so that the wrapper built for such a subprogram can
2508 -- be given the proper signature.
2510 -- Is_Private_Type (synthesized)
2511 -- Applies to all entities, true for private types and subtypes,
2512 -- as well as for record with private types as subtypes
2514 -- Is_Protected_Component (synthesized)
2515 -- Applicable to all entities, true if the entity denotes a private
2516 -- component of a protected type.
2518 -- Is_Protected_Interface (synthesized)
2519 -- Present in types that are interfaces. True if interface is declared
2520 -- protected, or is derived from protected interfaces.
2522 -- Is_Protected_Type (synthesized)
2523 -- Applies to all entities, true for protected types and subtypes
2525 -- Is_Public (Flag10)
2526 -- Present in all entities. Set to indicate that an entity defined in
2527 -- one compilation unit can be referenced from other compilation units.
2528 -- If this reference causes a reference in the generated variable, for
2529 -- example in the case of a variable name, then Gigi will generate an
2530 -- appropriate external name for use by the linker.
2532 -- Is_Protected_Record_Type (synthesized)
2533 -- Applies to all entities, true if Is_Concurrent_Record_Type
2534 -- Corresponding_Concurrent_Type is a protected type.
2537 -- Present in all entities. Set in all entities of a unit to which a
2538 -- pragma Pure is applied, and also set for the entity of the unit
2539 -- itself. In addition, this flag may be set for any other functions
2540 -- or procedures that are known to be side effect free, so in the case
2541 -- of subprograms, the Is_Pure flag may be used by the optimizer to
2542 -- imply that it can assume freedom from side effects (other than those
2543 -- resulting from assignment to out parameters, or to objects designated
2544 -- by access parameters).
2546 -- Is_Pure_Unit_Access_Type (Flag189)
2547 -- Present in access type and subtype entities. Set if the type or
2548 -- subtype appears in a pure unit. Used to give an error message at
2549 -- freeze time if the access type has a storage pool.
2551 -- Is_RACW_Stub_Type (Flag244)
2552 -- Present in all types, true for the stub types generated for remote
2553 -- access-to-class-wide types.
2555 -- Is_Raised (Flag224)
2556 -- Present in exception entities. Set if the entity is referenced by a
2557 -- a raise statement.
2559 -- Is_Real_Type (synthesized)
2560 -- Applies to all entities, true for real types and subtypes
2562 -- Is_Record_Type (synthesized)
2563 -- Applies to all entities, true for record types and subtypes,
2564 -- includes class-wide types and subtypes (which are also records)
2566 -- Is_Remote_Call_Interface (Flag62)
2567 -- Present in all entities. Set in E_Package and E_Generic_Package
2568 -- entities to which a pragma Remote_Call_Interface is applied, and
2569 -- also on entities declared in the visible part of such a package.
2571 -- Is_Remote_Types (Flag61)
2572 -- Present in all entities. Set in E_Package and E_Generic_Package
2573 -- entities to which a pragma Remote_Types is applied, and also on
2574 -- entities declared in the visible part of the spec of such a package.
2576 -- Is_Renaming_Of_Object (Flag112)
2577 -- Present in all entities, set only for a variable or constant for
2578 -- which the Renamed_Object field is non-empty and for which the
2579 -- renaming is handled by the front end, by macro substitution of
2580 -- a copy of the (evaluated) name tree whereever the variable is used.
2582 -- Is_Return_Object (Flag209)
2583 -- Present in all object entities. True if the object is the return
2584 -- object of an extended_return_statement; False otherwise.
2586 -- Is_Scalar_Type (synthesized)
2587 -- Applies to all entities, true for scalar types and subtypes
2589 -- Is_Shared_Passive (Flag60)
2590 -- Present in all entities. Set in E_Package and E_Generic_Package
2591 -- entities to which a pragma Shared_Passive is applied, and also in
2592 -- all entities within such packages.
2594 -- Is_Standard_Character_Type (synthesized)
2595 -- Applies to all entities, true for types and subtypes whose root type
2596 -- is one of the standard character types (Character, Wide_Character,
2597 -- Wide_Wide_Character).
2599 -- Is_Statically_Allocated (Flag28)
2600 -- Present in all entities. This can only be set True for exception,
2601 -- variable, constant, and type/subtype entities. If the flag is set,
2602 -- then the variable or constant must be allocated statically rather
2603 -- than on the local stack frame. For exceptions, the meaning is that
2604 -- the exception data should be allocated statically (and indeed this
2605 -- flag is always set for exceptions, since exceptions do not have
2606 -- local scope). For a type, the meaning is that the type must be
2607 -- elaborated at the global level rather than locally. No type marked
2608 -- with this flag may depend on a local variable, or on any other type
2609 -- which does not also have this flag set to True. For a variable or
2610 -- or constant, if the flag is set, then the type of the object must
2611 -- either be declared at the library level, or it must also have the
2612 -- flag set (since to allocate the object statically, its type must
2613 -- also be elaborated globally).
2615 -- Is_String_Type (synthesized)
2616 -- Applies to all type entities. Determines if the given type is a
2617 -- string type, i.e. it is directly a string type or string subtype,
2618 -- or a string slice type, or an array type with one dimension and a
2619 -- component type that is a character type.
2621 -- Is_Subprogram (synthesized)
2622 -- Applies to all entities, true for function, procedure and operator
2625 -- Is_Synchronized_Interface (synthesized)
2626 -- Present in types that are interfaces. True if interface is declared
2627 -- synchronized, task, or protected, or is derived from a synchronized
2631 -- Present in E_Component and E_Constant entities. For regular tagged
2632 -- type this flag is set on the tag component (whose name is Name_uTag).
2633 -- For CPP_Class tagged types, this flag marks the pointer to the main
2634 -- vtable (i.e. the one to be extended by derivation).
2636 -- Is_Tagged_Type (Flag55)
2637 -- Present in all entities. Set for an entity for a tagged type.
2639 -- Is_Task_Interface (synthesized)
2640 -- Present in types that are interfaces. True if interface is declared as
2641 -- a task interface, or if it is derived from task interfaces.
2643 -- Is_Task_Record_Type (synthesized)
2644 -- Applies to all entities. True if Is_Concurrent_Record_Type
2645 -- Corresponding_Concurrent_Type is a task type.
2647 -- Is_Task_Type (synthesized)
2648 -- Applies to all entities. True for task types and subtypes
2650 -- Is_Thunk (Flag225)
2651 -- Present in all entities for subprograms (functions, procedures, and
2652 -- operators). True for subprograms that are thunks, that is small
2653 -- subprograms built by the expander for tagged types that cover
2654 -- interface types. At run-time thunks displace the pointer to the object
2655 -- (pointer named "this" in the C++ terminology) from a secondary
2656 -- dispatch table to the primary dispatch table associated with a given
2657 -- tagged type. Set by Expand_Interface Thunk and used by Expand_Call to
2658 -- handle extra actuals associated with accessibility level.
2660 -- Is_Trivial_Subprogram (Flag235)
2661 -- Present in all entities. Set in subprograms where either the body
2662 -- consists of a single null statement, or the first or only statement
2663 -- of the body raises an exception. This is used for suppressing certain
2664 -- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details.
2666 -- Is_True_Constant (Flag163)
2667 -- Present in all entities for constants and variables. Set in constants
2668 -- and variables which have an initial value specified but which are
2669 -- never assigned, partially or in the whole. For variables, it means
2670 -- that the variable was initialized but never modified, and hence can be
2671 -- treated as a constant by the code generator. For a constant, it means
2672 -- that the constant was not modified by generated code (e.g. to set a
2673 -- discriminant in an init proc). Assignments by user or generated code
2674 -- will reset this flag.
2676 -- Is_Type (synthesized)
2677 -- Applies to all entities, true for a type entity
2679 -- Is_Unchecked_Union (Flag117) [implementation base type only]
2680 -- Present in all entities. Set only in record types to which the
2681 -- pragma Unchecked_Union has been validly applied.
2683 -- Is_Underlying_Record_View (Flag246) [base type only]
2684 -- Present in all entities. Set only in record types that represent the
2685 -- underlying record view. This view is built for derivations of types
2686 -- with unknown discriminants; it is a record with the same structure
2687 -- as its corresponding record type, but whose parent is the full view
2688 -- of the parent in the original type extension.
2690 -- Is_Unsigned_Type (Flag144)
2691 -- Present in all types, but can be set only for discrete and fixed-point
2692 -- type and subtype entities. This flag is only valid if the entity is
2693 -- frozen. If set it indicates that the representation is known to be
2694 -- unsigned (i.e. that no negative values appear in the range). This is
2695 -- normally just a reflection of the lower bound of the subtype or base
2696 -- type, but there is one case in which the setting is non-obvious,
2697 -- namely the case of an unsigned subtype of a signed type from which
2698 -- a further subtype is obtained using variable bounds. This further
2699 -- subtype is still unsigned, but this cannot be determined by looking
2700 -- at its bounds or the bounds of the corresponding base type.
2702 -- Is_Valued_Procedure (Flag127)
2703 -- Present in procedure entities. Set if an Import_Valued_Procedure
2704 -- or Export_Valued_Procedure pragma applies to the procedure entity.
2706 -- Is_Visible_Child_Unit (Flag116)
2707 -- Present in compilation units that are child units. Once compiled,
2708 -- child units remain chained to the entities in the parent unit, and
2709 -- a separate flag must be used to indicate whether the names are
2710 -- visible by selected notation, or not.
2712 -- Is_Visible_Formal (Flag206)
2713 -- Present in all entities. Set for instances of the formals of a formal
2714 -- package. Indicates that the entity must be made visible in the body
2715 -- of the instance, to reproduce the visibility of the generic. This
2716 -- simplifies visibility settings in instance bodies.
2717 -- ??? confusion in above comments between being present and being set
2719 -- Is_VMS_Exception (Flag133)
2720 -- Present in all entities. Set only for exception entities where the
2721 -- exception was specified in an Import_Exception or Export_Exception
2722 -- pragma with the VMS option for Form. See description of these pragmas
2723 -- for details. This flag can only be set in OpenVMS versions of GNAT.
2725 -- Is_Volatile (Flag16)
2726 -- Present in all type entities, and also in constants, components and
2727 -- variables. Set if a pragma Volatile applies to the entity. Also set
2728 -- if pragma Shared or pragma Atomic applies to entity. In the case of
2729 -- private or incomplete types, this flag is set in both the private
2730 -- and full view. The flag is not set reliably on private subtypes,
2731 -- and is always retrieved from the base type (but this is not a base-
2732 -- type-only attribute because it applies to other entities). Note that
2733 -- the back end should use Treat_As_Volatile, rather than Is_Volatile
2734 -- to indicate code generation requirements for volatile variables.
2735 -- Similarly, any front end test which is concerned with suppressing
2736 -- optimizations on volatile objects should test Treat_As_Volatile
2737 -- rather than testing this flag.
2739 -- Is_Wrapper_Package (synthesized)
2740 -- Present in package entities. Indicates that the package has been
2741 -- created as a wrapper for a subprogram instantiation.
2743 -- Itype_Printed (Flag202)
2744 -- Present in all type and subtype entities. Set in Itypes if the Itype
2745 -- has been printed by Sprint. This is used to avoid printing an Itype
2748 -- Kill_Elaboration_Checks (Flag32)
2749 -- Present in all entities. Set by the expander to kill elaboration
2750 -- checks which are known not to be needed. Equivalent in effect to
2751 -- the use of pragma Suppress (Elaboration_Checks) for that entity
2752 -- except that the effect is permanent and cannot be undone by a
2753 -- subsequent pragma Unsuppress.
2755 -- Kill_Range_Checks (Flag33)
2756 -- Present in all entities. Equivalent in effect to the use of pragma
2757 -- Suppress (Range_Checks) for that entity except that the result is
2758 -- permanent and cannot be undone by a subsequent pragma Unsuppress.
2759 -- This is currently only used in one odd situation in Sem_Ch3 for
2760 -- record types, and it would be good to get rid of it???
2762 -- Kill_Tag_Checks (Flag34)
2763 -- Present in all entities. Set by the expander to kill elaboration
2764 -- checks which are known not to be needed. Equivalent in effect to
2765 -- the use of pragma Suppress (Tag_Checks) for that entity except
2766 -- that the result is permanent and cannot be undone by a subsequent
2767 -- pragma Unsuppress.
2769 -- Known_To_Have_Preelab_Init (Flag207)
2770 -- Present in all type and subtype entities. If set, then the type is
2771 -- known to have preelaborable initialization. In the case of a partial
2772 -- view of a private type, it is only possible for this to be set if a
2773 -- pragma Preelaborable_Initialization is given for the type. For other
2774 -- types, it is never set if the type does not have preelaborable
2775 -- initialization, it may or may not be set if the type does have
2776 -- preelaborable initialization.
2778 -- Last_Assignment (Node26)
2779 -- Present in entities for variables, and OUT or IN OUT formals. Set for
2780 -- a local variable or formal to point to the left side of an assignment
2781 -- statement assigning a value to the variable. Cleared if the value of
2782 -- the entity is referenced. Used to warn about dubious assignment
2783 -- statements whose value is not used.
2785 -- Last_Entity (Node20)
2786 -- Present in all entities which act as scopes to which a list of
2787 -- associated entities is attached (blocks, class subtypes and types,
2788 -- entries, functions, loops, packages, procedures, protected objects,
2789 -- record types and subtypes, private types, task types and subtypes).
2790 -- Points to the last entry in the list of associated entities chained
2791 -- through the Next_Entity field. Empty if no entities are chained.
2793 -- Last_Formal (synthesized)
2794 -- Applies to subprograms and subprogram types, and also in entries
2795 -- and entry families. Returns last formal of the subprogram or entry.
2796 -- The formals are the first entities declared in a subprogram or in
2797 -- a subprogram type (the designated type of an Access_To_Subprogram
2798 -- definition) or in an entry.
2800 -- Limited_View (Node23)
2801 -- Present in non-generic package entities that are not instances. Bona
2802 -- fide package with the limited-view list through the first_entity and
2803 -- first_private attributes. The elements of this list are the shadow
2804 -- entities created for the types and local packages that are declared
2805 -- in a package appearing in a limited_with clause (Ada 2005: AI-50217)
2807 -- Lit_Indexes (Node15)
2808 -- Present in enumeration types and subtypes. Non-empty only for the
2809 -- case of an enumeration root type, where it contains the entity for
2810 -- the generated indexes entity. See unit Exp_Imgv for full details of
2811 -- the nature and use of this entity for implementing the Image and
2812 -- Value attributes for the enumeration type in question.
2814 -- Lit_Strings (Node16)
2815 -- Present in enumeration types and subtypes. Non-empty only for the
2816 -- case of an enumeration root type, where it contains the entity for
2817 -- the literals string entity. See unit Exp_Imgv for full details of
2818 -- the nature and use of this entity for implementing the Image and
2819 -- Value attributes for the enumeration type in question.
2821 -- Low_Bound_Tested (Flag205)
2822 -- Present in all entities. Currently this can only be set True for
2823 -- formal parameter entries of a standard unconstrained one-dimensional
2824 -- array or string type. Indicates that an explicit test of the low bound
2825 -- of the formal appeared in the code, e.g. in a pragma Assert. If this
2826 -- flag is set, warnings about assuming the index low bound to be one
2829 -- Machine_Radix_10 (Flag84)
2830 -- Present in decimal types and subtypes, set if the Machine_Radix
2831 -- is 10, as the result of the specification of a machine radix
2832 -- representation clause. Note that it is possible for this flag
2833 -- to be set without having Has_Machine_Radix_Clause True. This
2834 -- happens when a type is derived from a type with a clause present.
2836 -- Master_Id (Node17)
2837 -- Present in access types and subtypes. Empty unless Has_Task is
2838 -- set for the designated type, in which case it points to the entity
2839 -- for the Master_Id for the access type master. Also set for access-to-
2840 -- limited-class-wide types whose root may be extended with task
2841 -- components, and for access-to-limited-interfaces because they can be
2842 -- used to reference tasks implementing such interface.
2844 -- Materialize_Entity (Flag168)
2845 -- Present in all entities. Set only for constant or renamed entities
2846 -- which should be materialized for debugging purposes. In the case of
2847 -- a constant, a memory location should be allocated containing the
2848 -- value. In the case of a renaming, a memory location containing the
2849 -- renamed address should be allocated.
2851 -- Mechanism (Uint8) (returned as Mechanism_Type)
2852 -- Present in functions and non-generic formal parameters. Indicates
2853 -- the mechanism to be used for the function return or for the formal
2854 -- parameter. See separate section on passing mechanisms. This field
2855 -- is also set (to the default value of zero) in a subprogram body
2856 -- entity but not used in this context.
2858 -- Modulus (Uint17) [base type only]
2859 -- Present in modular types. Contains the modulus. For the binary
2860 -- case, this will be a power of 2, but if Non_Binary_Modulus is
2861 -- set, then it will not be a power of 2.
2863 -- Must_Be_On_Byte_Boundary (Flag183)
2864 -- Present in entities for types and subtypes. Set if objects of
2865 -- the type must always be allocated on a byte boundary (more
2866 -- accurately a storage unit boundary). The front end checks that
2867 -- component clauses respect this rule, and the back end ensures
2868 -- that record packing does not violate this rule. Currently the
2869 -- flag is set only for packed arrays longer than 64 bits where
2870 -- the component size is not a power of 2.
2872 -- Must_Have_Preelab_Init (Flag208)
2873 -- Present in entities for types and subtypes. Set in the full type of a
2874 -- private type or subtype if a pragma Has_Preelaborable_Initialization
2875 -- is present for the private type. Used to check that the full type has
2876 -- preelaborable initialization at freeze time (this has to be deferred
2877 -- to the freeze point because of the rule about overriding Initialize).
2879 -- Needs_Debug_Info (Flag147)
2880 -- Present in all entities. Set if the entity requires normal debugging
2881 -- information to be generated. This is true of all entities that have
2882 -- Comes_From_Source set, and also transitively for entities associated
2883 -- with such components (e.g. their types). It is true for all entities
2884 -- in Debug_Generated_Code mode (-gnatD switch). This is the flag that
2885 -- the back end should check to determine whether or not to generate
2886 -- debugging information for an entity. Note that callers should always
2887 -- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info,
2888 -- so that the flag is set properly on subsidiary entities.
2890 -- Needs_No_Actuals (Flag22)
2891 -- Present in callable entities (subprograms, entries, access to
2892 -- subprograms) which can be called without actuals because all of
2893 -- their formals (if any) have default values. This flag simplifies the
2894 -- resolution of the syntactic ambiguity involving a call to these
2895 -- entities when the return type is an array type, and a call can be
2896 -- interpreted as an indexing of the result of the call. It is also
2897 -- used to resolve various cases of entry calls.
2899 -- Never_Set_In_Source (Flag115)
2900 -- Present in all entities, but can be set only for variables and
2901 -- parameters. This flag is set if the object is never assigned a value
2902 -- in user source code, either by assignment or by being used as an out
2903 -- or in out parameter. Note that this flag is not reset from using an
2904 -- initial value, so if you want to test for this case as well, test the
2905 -- Has_Initial_Value flag also.
2907 -- This flag is only for the purposes of issuing warnings, it must not
2908 -- be used by the code generator to indicate that the variable is in
2909 -- fact a constant, since some assignments in generated code do not
2910 -- count (for example, the call to an init proc to assign some but
2911 -- not all of the fields in a partially initialized record). The code
2912 -- generator should instead use the flag Is_True_Constant.
2914 -- For the purposes of this warning, the default assignment of
2915 -- access variables to null is not considered the assignment of
2916 -- of a value (so the warning can be given for code that relies
2917 -- on this initial null value, when no other value is ever set).
2919 -- In variables and out parameters, if this flag is set after full
2920 -- processing of the corresponding declarative unit, it indicates that
2921 -- the variable or parameter was never set, and a warning message can
2924 -- Note: this flag is initially set, and then cleared on encountering
2925 -- any construct that might conceivably legitimately set the value.
2926 -- Thus during the analysis of a declarative region and its associated
2927 -- statement sequence, the meaning of the flag is "not set yet", and
2928 -- once this analysis is complete the flag means "never assigned".
2930 -- Note: for variables appearing in package declarations, this flag
2931 -- is never set. That is because there is no way to tell if some
2932 -- client modifies the variable (or in the case of variables in the
2933 -- private part, if some child unit modifies the variables).
2935 -- Note: in the case of renamed objects, the flag must be set in the
2936 -- ultimate renamed object. Clients noting a possible modification
2937 -- should use the Note_Possible_Modification procedure in Sem_Util
2938 -- rather than Set_Never_Set_In_Source precisely to deal properly with
2939 -- the renaming possibility.
2941 -- Next_Component (synthesized)
2942 -- Applies to record components. Returns the next component by following
2943 -- the chain of declared entities until one is found which corresponds to
2944 -- a component (Ekind is E_Component). Any internal types generated from
2945 -- the subtype indications of the record components are skipped. Returns
2946 -- Empty if no more components.
2948 -- Next_Component_Or_Discriminant (synthesized)
2949 -- Similar to Next_Component, but includes components and discriminants
2950 -- so the input can have either E_Component or E_Discriminant, and the
2951 -- same is true for the result. Returns Empty if no more components or
2952 -- discriminants in the record.
2954 -- Next_Discriminant (synthesized)
2955 -- Applies to discriminants returned by First/Next_Discriminant.
2956 -- Returns the next language-defined (ie: perhaps non-girder)
2957 -- discriminant by following the chain of declared entities as long as
2958 -- the kind of the entity corresponds to a discriminant. Note that the
2959 -- discriminants might be the only components of the record.
2960 -- Returns Empty if there are no more.
2962 -- Next_Entity (Node2)
2963 -- Present in all entities. The entities of a scope are chained, with
2964 -- the head of the list being in the First_Entity field of the scope
2965 -- entity. All entities use the Next_Entity field as a forward pointer
2966 -- for this list, with Empty indicating the end of the list. Since this
2967 -- field is in the base part of the entity, the access routines for this
2968 -- field are in Sinfo.
2970 -- Next_Formal (synthesized)
2971 -- Applies to the entity for a formal parameter. Returns the next
2972 -- formal parameter of the subprogram or subprogram type. Returns
2973 -- Empty if there are no more formals.
2975 -- Next_Formal_With_Extras (synthesized)
2976 -- Applies to the entity for a formal parameter. Returns the next
2977 -- formal parameter of the subprogram or subprogram type. Returns
2978 -- Empty if there are no more formals. The list returned includes
2979 -- all the extra formals (see description of Extra_Formal field)
2981 -- Next_Girder_Discriminant (synthesized)
2982 -- Applies to discriminants. Set only for a discriminant returned by
2983 -- a call to First/Next_Girder_Discriminant. Returns next girder
2984 -- discriminant, if there are more (see complete description in
2985 -- First_Girder_Discriminant), or Empty if there are no more.
2987 -- Next_Index (synthesized)
2988 -- Applies to array types and subtypes and to string types and
2989 -- subtypes. Yields the next index. The first index is obtained by
2990 -- using the First_Index attribute, and then subsequent indexes are
2991 -- obtained by applying Next_Index to the previous index. Empty is
2992 -- returned to indicate that there are no more indexes. Note that
2993 -- unlike most attributes in this package, Next_Index applies to
2994 -- nodes for the indexes, not to entities.
2996 -- Next_Inlined_Subprogram (Node12)
2997 -- Present in subprograms. Used to chain inlined subprograms used in
2998 -- the current compilation, in the order in which they must be compiled
2999 -- by Gigi to insure that all inlinings are performed.
3001 -- Next_Literal (synthesized)
3002 -- Applies to enumeration literals, returns the next literal, or
3003 -- Empty if applied to the last literal. This is actually a synonym
3004 -- for Next, but its use is preferred in this context.
3006 -- Non_Binary_Modulus (Flag58) [base type only]
3007 -- Present in all subtype and type entities. Set for modular integer
3008 -- types if the modulus value is other than a power of 2.
3010 -- Non_Limited_View (Node17)
3011 -- Present in incomplete types that are the shadow entities created
3012 -- when analyzing a limited_with_clause (Ada 2005: AI-50217). Points to
3013 -- the defining entity in the original declaration.
3015 -- Nonzero_Is_True (Flag162) [base type only]
3016 -- Present in enumeration types. True if any non-zero value is to be
3017 -- interpreted as true. Currently this is set true for derived Boolean
3018 -- types which have a convention of C, C++ or Fortran.
3020 -- No_Pool_Assigned (Flag131) [root type only]
3021 -- Present in access types. Set if a storage size clause applies to
3022 -- the variable with a compile time known value of zero. This flag is
3023 -- used to generate warnings if any attempt is made to allocate or free
3024 -- an instance of such an access type. This is set only in the root
3025 -- type, since derived types must have the same pool.
3027 -- No_Return (Flag113)
3028 -- Present in all entities. Always false except in the case of procedures
3029 -- and generic procedures for which a pragma No_Return is given.
3031 -- Normalized_First_Bit (Uint8)
3032 -- Present in components and discriminants. Indicates the normalized
3033 -- value of First_Bit for the component, i.e. the offset within the
3034 -- lowest addressed storage unit containing part or all of the field.
3035 -- Set to No_Uint if no first bit position is assigned yet.
3037 -- Normalized_Position (Uint14)
3038 -- Present in components and discriminants. Indicates the normalized
3039 -- value of Position for the component, i.e. the offset in storage
3040 -- units from the start of the record to the lowest addressed storage
3041 -- unit containing part or all of the field.
3043 -- Normalized_Position_Max (Uint10)
3044 -- Present in components and discriminants. For almost all cases, this
3045 -- is the same as Normalized_Position. The one exception is for the case
3046 -- of a discriminated record containing one or more arrays whose length
3047 -- depends on discriminants. In this case, the Normalized_Position_Max
3048 -- field represents the maximum possible value of Normalized_Position
3049 -- assuming min/max values for discriminant subscripts in all fields.
3050 -- This is used by Layout in front end layout mode to properly computed
3051 -- the maximum size such records (needed for allocation purposes when
3052 -- there are default discriminants, and also for the 'Size value).
3054 -- No_Strict_Aliasing (Flag136) [base type only]
3055 -- Present in access types. Set to direct the back end to avoid any
3056 -- optimizations based on an assumption about the aliasing status of
3057 -- objects designated by the access type. For the case of the gcc
3058 -- back end, the effect is as though all references to objects of
3059 -- the type were compiled with -fno-strict-aliasing. This flag is
3060 -- set if an unchecked conversion with the access type as a target
3061 -- type occurs in the same source unit as the declaration of the
3062 -- access type, or if an explicit pragma No_Strict_Aliasing applies.
3064 -- Number_Dimensions (synthesized)
3065 -- Applies to array types and subtypes. Returns the number of dimensions
3066 -- of the array type or subtype as a value of type Pos.
3068 -- Number_Entries (synthesized)
3069 -- Applies to concurrent types. Returns the number of entries that are
3070 -- declared within the task or protected definition for the type.
3072 -- Number_Formals (synthesized)
3073 -- Applies to subprograms and subprogram types. Yields the number of
3074 -- formals as a value of type Pos.
3076 -- OK_To_Rename (Flag247)
3077 -- Present only in entities for variables. If this flag is set, it
3078 -- means that if the entity is used as the initial value of an object
3079 -- declaration, the object declaration can be safely converted into a
3080 -- renaming to avoid an extra copy. This is set for variables which are
3081 -- generated by the expander to hold the result of evaluating some
3082 -- expression. Most notably, the local variables used to store the result
3083 -- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It
3084 -- is only worth setting this flag for composites, since for primitive
3085 -- types, it is cheaper to do the copy.
3087 -- OK_To_Reorder_Components (Flag239) [base type only]
3088 -- Present in record types. Set if the back end is permitted to reorder
3089 -- the components. If not set, the record must be layed out in the order
3090 -- in which the components are declared textually. Currently this flag
3091 -- can only be set by debug switches.
3093 -- Optimize_Alignment_Space (Flag241)
3094 -- A flag present in type, subtype, variable, and constant entities. This
3095 -- flag records that the type or object is to be layed out in a manner
3096 -- consistent with Optimize_Alignment (Space) mode. The compiler and
3097 -- binder ensure a consistent view of any given type or object. If pragma
3098 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3099 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3101 -- Optimize_Alignment_Time (Flag242)
3102 -- A flag present in type, subtype, variable, and constant entities. This
3103 -- flag records that the type or object is to be layed out in a manner
3104 -- consistent with Optimize_Alignment (Time) mode. The compiler and
3105 -- binder ensure a consistent view of any given type or object. If pragma
3106 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3107 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3109 -- Original_Array_Type (Node21)
3110 -- Present in modular types and array types and subtypes. Set only
3111 -- if the Is_Packed_Array_Type flag is set, indicating that the type
3112 -- is the implementation type for a packed array, and in this case it
3113 -- points to the original array type for which this is the packed
3114 -- array implementation type.
3116 -- Original_Record_Component (Node22)
3117 -- Present in components, including discriminants. The usage depends
3118 -- on whether the record is a base type and whether it is tagged.
3120 -- In base tagged types:
3121 -- When the component is inherited in a record extension, it points
3122 -- to the original component (the entity of the ancestor component
3123 -- which is not itself inherited) otherwise it points to itself.
3124 -- Gigi uses this attribute to implement the automatic dereference in
3125 -- the extension and to apply the transformation:
3127 -- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
3129 -- In base non-tagged types:
3130 -- Always points to itself except for non-girder discriminants, where
3131 -- it points to the girder discriminant it renames.
3133 -- In subtypes (tagged and untagged):
3134 -- Points to the component in the base type.
3136 -- Overlays_Constant (Flag243)
3137 -- Present in all entities. Set only for a variable for which there is
3138 -- an address clause which causes the variable to overlay a constant.
3140 -- Overridden_Operation (Node26)
3141 -- Present in subprograms. For overriding operations, points to the
3142 -- user-defined parent subprogram that is being overridden.
3144 -- Package_Instantiation (Node26)
3145 -- Present in packages and generic packages. When present, this field
3146 -- references an N_Package_Instantiation node associated with an
3147 -- instantiated package. In the case where the referenced node has
3148 -- been rewritten to an N_Package_Specification, the instantiation
3149 -- node is available from the Original_Node field of the package spec
3150 -- node. This is currently not guaranteed to be set in all cases, but
3151 -- when set, the field is used in Get_Package_Instantiation_Node as
3152 -- one of the means of obtaining the instantiation node. Eventually
3153 -- it should be set in all cases, including package entities associated
3154 -- with formal packages. ???
3156 -- Packed_Array_Type (Node23)
3157 -- Present in array types and subtypes, including the string literal
3158 -- subtype case, if the corresponding type is packed (either bit packed
3159 -- or packed to eliminate holes in non-contiguous enumeration type index
3160 -- types). References the type used to represent the packed array, which
3161 -- is either a modular type for short static arrays, or an array of
3162 -- System.Unsigned. Note that in some situations (internal types, and
3163 -- references to fields of variant records), it is not always possible
3164 -- to construct this type in advance of its use. If Packed_Array_Type
3165 -- is empty, then the necessary type is declared on the fly for each
3166 -- reference to the array.
3168 -- Parameter_Mode (synthesized)
3169 -- Applies to formal parameter entities. This is a synonym for Ekind,
3170 -- used when obtaining the formal kind of a formal parameter (the result
3171 -- is one of E_[In/Out/In_Out]_Parameter)
3173 -- Parent_Subtype (Node19) [base type only]
3174 -- Present in E_Record_Type. Set only for derived tagged types, in which
3175 -- case it points to the subtype of the parent type. This is the type
3176 -- that is used as the Etype of the _parent field.
3178 -- Postcondition_Proc (Node8)
3179 -- Present only in procedure entities, saves the entity of the generated
3180 -- postcondition proc if one is present, otherwise is set to Empty. Used
3181 -- to generate the call to this procedure in case the expander inserts
3182 -- implicit return statements.
3184 -- Primitive_Operations (Elist15)
3185 -- Present in tagged record types and subtypes and in tagged private
3186 -- types. Points to an element list of entities for primitive operations
3187 -- for the tagged type. Not present (and not set) in untagged types (it
3188 -- is an error to reference the primitive operations field of a type
3189 -- that is not tagged). In order to fulfill the C++ ABI, entities of
3190 -- primitives that come from source must be stored in this list following
3191 -- their order of occurrence in the sources.
3194 -- Present in private components of protected types. Refers to the entity
3195 -- of the component renaming declaration generated inside protected
3196 -- subprograms, entries or barrier functions.
3198 -- Prival_Link (Node20)
3199 -- Present in constants and variables which rename private components of
3200 -- protected types. Set to the original private component.
3202 -- Private_Dependents (Elist18)
3203 -- Present in private (sub)types. Records the subtypes of the private
3204 -- type, derivations from it, and records and arrays with components
3205 -- dependent on the type.
3207 -- The subtypes are traversed when installing and deinstalling (the full
3208 -- view of) a private type in order to ensure correct view of the
3211 -- Used in similar fashion for incomplete types: holds list of subtypes
3212 -- of these incomplete types that have discriminant constraints. The
3213 -- full views of these subtypes are constructed when the full view of
3214 -- the incomplete type is processed.
3216 -- In addition, if the incomplete type is the designated type in an
3217 -- access definition for an access parameter, the operation may be
3218 -- a dispatching primitive operation, which is only known when the full
3219 -- declaration of the type is seen. Subprograms that have such an
3220 -- access parameter are also placed in the list of private_dependents.
3222 -- Private_View (Node22)
3223 -- For each private type, three entities are allocated, the private view,
3224 -- the full view, and the shadow entity. The shadow entity contains a
3225 -- copy of the private view and is used for restoring the proper private
3226 -- view after a region in which the full view is visible (and is copied
3227 -- into the entity normally used for the private view during this period
3228 -- of visibility). The Private_View field is self-referential when the
3229 -- private view lives in its normal entity, but in the copy that is made
3230 -- in the shadow entity, it points to the proper location in which to
3231 -- restore the private view saved in the shadow.
3233 -- Protected_Formal (Node22)
3234 -- Present in formal parameters (in, in out and out parameters). Used
3235 -- only for formals of protected operations. References corresponding
3236 -- formal parameter in the unprotected version of the operation that
3237 -- is created during expansion.
3239 -- Protected_Body_Subprogram (Node11)
3240 -- Present in protected operations. References the entity for the
3241 -- subprogram which implements the body of the operation.
3243 -- Protection_Object (Node23)
3244 -- Applies to protected entries, entry families and subprograms. Denotes
3245 -- the entity which is used to rename the _object component of protected
3248 -- Reachable (Flag49)
3249 -- Present in labels. The flag is set over the range of statements in
3250 -- which a goto to that label is legal.
3252 -- Referenced (Flag156)
3253 -- Present in all entities. Set if the entity is referenced, except for
3254 -- the case of an appearance of a simple variable that is not a renaming
3255 -- as the left side of an assignment in which case Referenced_As_LHS is
3256 -- set instead, or a similar appearance as an out parameter actual, in
3257 -- which case Referenced_As_Out_Parameter is set.
3259 -- Referenced_As_LHS (Flag36):
3260 -- Present in all entities. This flag is set instead of Referenced if a
3261 -- simple variable that is not a renaming appears as the left side of an
3262 -- assignment. The reason we distinguish this kind of reference is that
3263 -- we have a separate warning for variables that are only assigned and
3266 -- Referenced_As_Out_Parameter (Flag227):
3267 -- Present in all entities. This flag is set instead of Referenced if a
3268 -- simple variable that is not a renaming appears as an actual for an out
3269 -- formal. The reason we distinguish this kind of reference is that
3270 -- we have a separate warning for variables that are only assigned and
3271 -- never read, and out parameters are a special case.
3273 -- Referenced_Object (Node10)
3274 -- Present in all type entities. Set non-Empty only for type entities
3275 -- constructed for unconstrained objects, or objects that depend on
3276 -- discriminants. Points to the expression from which the actual
3277 -- subtype of the object can be evaluated.
3279 -- Register_Exception_Call (Node20)
3280 -- Present in exception entities. When an exception is declared,
3281 -- a call is expanded to Register_Exception. This field points to
3282 -- the expanded N_Procedure_Call_Statement node for this call. It
3283 -- is used for Import/Export_Exception processing to modify the
3284 -- register call to make appropriate entries in the special tables
3285 -- used for handling these pragmas at runtime.
3287 -- Related_Array_Object (Node19)
3288 -- Present in array types and subtypes. Used only for the base type
3289 -- and subtype created for an anonymous array object. Set to point
3290 -- to the entity of the corresponding array object. Currently used
3291 -- only for type-related error messages.
3293 -- Related_Expression (Node24)
3294 -- Present in variables and types. Set only for internally generated
3295 -- entities, where it may be used to denote the source expression whose
3296 -- elaboration created the variable declaration. If set, it is used
3297 -- for generating clearer messages from CodePeer.
3299 -- Shouldn't it also be used for the same purpose in errout? It seems
3300 -- odd to have two mechanisms here???
3302 -- Related_Instance (Node15)
3303 -- Present in the wrapper packages created for subprogram instances.
3304 -- The internal subprogram that implements the instance is inside the
3305 -- wrapper package, but for debugging purposes its external symbol
3306 -- must correspond to the name and scope of the related instance.
3308 -- Related_Type (Node26)
3309 -- Present in components and constants associated with dispatch tables.
3310 -- Set to point to the entity of the associated tagged type or interface
3313 -- Relative_Deadline_Variable (Node26) [implementation base type only]
3314 -- Present in task type entities. This flag is set if a valid and
3315 -- effective pragma Relative_Deadline applies to the base type. Points
3316 -- to the entity for a variable that is created to hold the value given
3317 -- in a Relative_Deadline pragma for a task type.
3319 -- Renamed_Entity (Node18)
3320 -- Present in exceptions, packages, subprograms and generic units. Set
3321 -- for entities that are defined by a renaming declaration. Denotes the
3322 -- renamed entity, or transitively the ultimate renamed entity if
3323 -- there is a chain of renaming declarations. Empty if no renaming.
3325 -- Renamed_In_Spec (Flag231)
3327 -- Present in package entities. If a package renaming occurs within
3328 -- a package spec, then this flag is set on the renamed package. The
3329 -- purpose is to prevent a warning about unused entities in the renamed
3330 -- package. Such a warning would be inappropriate since clients of the
3331 -- package can see the entities in the package via the renaming.
3333 -- Renamed_Object (Node18)
3334 -- Present in all objects (constants, variables, components, formal
3335 -- parameters, generic formal parameters, and loop parameters).
3336 -- ??? Present in discriminants?
3337 -- Set non-Empty if the object was declared by a renaming declaration,
3338 -- in which case it references the tree node for the name of the renamed
3339 -- object. This is only possible for the variable and constant cases.
3340 -- For formal parameters, this field is used in the course of inline
3341 -- expansion, to map the formals of a subprogram into the corresponding
3342 -- actuals. For formals of a task entry, it denotes the local renaming
3343 -- that replaces the actual within the accept statement. The field is
3344 -- Empty otherwise (it is always empty for loop parameters).
3346 -- Renaming_Map (Uint9)
3347 -- Present in generic subprograms, generic packages, and their
3348 -- instances. Also present in the instances of the corresponding
3349 -- bodies. Denotes the renaming map (generic entities => instance
3350 -- entities) used to construct the instance by givin an index into
3351 -- the tables used to represent these maps. See Sem_Ch12 for further
3352 -- details. The maps for package instances are also used when the
3353 -- instance is the actual corresponding to a formal package.
3355 -- Requires_Overriding (Flag213)
3356 -- Present in all subprograms and entries. Set for subprograms that
3357 -- require overriding as defined by RM-2005-3.9.3(6/2). Note that this
3358 -- is True only for implicitly declare subprograms; it is not set on the
3359 -- parent type's subprogram. See also Is_Abstract_Subprogram.
3361 -- Return_Present (Flag54)
3362 -- Present in function and generic function entities. Set if the
3363 -- function contains a return statement (used for error checking).
3364 -- This flag can also be set in procedure and generic procedure
3365 -- entities (for convenience in setting it), but is only tested
3366 -- for the function case.
3368 -- Return_Applies_To (Node8)
3369 -- Present in E_Return_Statement. Points to the entity representing
3370 -- the construct to which the return statement applies, as defined in
3371 -- RM-6.5(4/2). Note that a (simple) return statement within an
3372 -- extended_return_statement applies to the extended_return_statement,
3373 -- even though it causes the whole function to return.
3375 -- Returns_By_Ref (Flag90)
3376 -- Present in function entities, to indicate that the function
3377 -- returns the result by reference, either because its return type is a
3378 -- by-reference-type or because it uses explicitly the secondary stack.
3380 -- Reverse_Bit_Order (Flag164) [base type only]
3381 -- Present in all record type entities. Set if a valid pragma an
3382 -- attribute representation clause for Bit_Order has reversed the order
3383 -- of bits from the default value. When this flag is set, a component
3384 -- clause must specify a set of bits entirely contained in a single
3385 -- storage unit (Ada 95) or a single machine scalar (see Ada 2005
3386 -- AI-133), or must occupy in integral number of storage units.
3389 -- Present in all type and subtype entities. Contains the value of
3390 -- type'Size as defined in the RM. See also the Esize field and
3391 -- and the description on "Handling of Type'Size Values". A value
3392 -- of zero in this field for a non-discrete type means that
3393 -- the front end has not yet determined the size value. For the
3394 -- case of a discrete type, this field is always set by the front
3395 -- end and zero is a legitimate value for a type with one value.
3397 -- Root_Type (synthesized)
3398 -- Applies to all type entities. For class-wide types, return the root
3399 -- type of the class covered by the CW type, otherwise returns the
3400 -- ultimate derivation ancestor of the given type. This function
3401 -- preserves the view, i.e. the Root_Type of a partial view is the
3402 -- partial view of the ultimate ancestor, the Root_Type of a full view
3403 -- is the full view of the ultimate ancestor. Note that this function
3404 -- does not correspond exactly to the use of root type in the RM, since
3405 -- in the RM root type applies to a class of types, not to a type.
3407 -- Scalar_Range (Node20)
3408 -- Present in all scalar types (including modular types, where the
3409 -- bounds are 0 .. modulus - 1). References a node in the tree that
3410 -- contains the bounds for the range. Note that this information
3411 -- could be obtained by rummaging around the tree, but it is more
3412 -- convenient to have it immediately at hand in the entity. The
3413 -- contents of Scalar_Range can either be an N_Subtype_Indication
3414 -- node (with a constraint), or a Range node, but not a simple
3415 -- subtype reference (a subtype is converted into a range).
3417 -- Scale_Value (Uint15)
3418 -- Present in decimal fixed-point types and subtypes. Contains the scale
3419 -- for the type (i.e. the value of type'Scale = the number of decimal
3420 -- digits after the decimal point).
3423 -- Present in all entities. Points to the entity for the scope (block,
3424 -- loop, subprogram, package etc.) in which the entity is declared.
3425 -- Since this field is in the base part of the entity node, the access
3426 -- routines for this field are in Sinfo. Note that for a child package,
3427 -- the Scope will be the parent package, and for a non-child package,
3428 -- the Scope will be Standard.
3430 -- Scope_Depth (synthesized)
3431 -- Applies to program units, blocks, concurrent types and entries, and
3432 -- also to record types, i.e. to any entity that can appear on the scope
3433 -- stack. Yields the scope depth value, which for those entities other
3434 -- than records is simply the scope depth value, for record entities, it
3435 -- is the Scope_Depth of the record scope.
3437 -- Scope_Depth_Value (Uint22)
3438 -- Present in program units, blocks, concurrent types, and entries.
3439 -- Indicates the number of scopes that statically enclose the declaration
3440 -- of the unit or type. Library units have a depth of zero. Note that
3441 -- record types can act as scopes but do NOT have this field set (see
3442 -- Scope_Depth above)
3444 -- Scope_Depth_Set (synthesized)
3445 -- Applies to a special predicate function that returns a Boolean value
3446 -- indicating whether or not the Scope_Depth field has been set. It is
3447 -- needed, since returns an invalid value in this case!
3449 -- Sec_Stack_Needed_For_Return (Flag167)
3450 -- Present in scope entities (blocks, functions, procedures, tasks,
3451 -- entries). Set to True when secondary stack is used to hold the
3452 -- returned value of a function and thus should not be released on
3455 -- Shadow_Entities (List14)
3456 -- Present in package and generic package entities. Points to a list
3457 -- of entities that correspond to private types. For each private type
3458 -- a shadow entity is created that holds a copy of the private view.
3459 -- In regions of the program where the full views of these private
3460 -- entities are visible, the full view is copied into the entity that
3461 -- is normally used to hold the private view, but the shadow entity
3462 -- copy is unchanged. The shadow entities are then used to restore the
3463 -- original private views at the end of the region. This list is a
3464 -- standard format list (i.e. First (Shadow_Entities) is the first
3465 -- entry and subsequent entries are obtained using Next.
3467 -- Shared_Var_Procs_Instance (Node22)
3468 -- Present in variables. Set non-Empty only if Is_Shared_Passive is
3469 -- set, in which case this is the entity for the associated instance of
3470 -- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details.
3472 -- Size_Check_Code (Node19)
3473 -- Present in constants and variables. Normally Empty. Set if code is
3474 -- generated to check the size of the object. This field is used to
3475 -- suppress this code if a subsequent address clause is encountered.
3477 -- Size_Clause (synthesized)
3478 -- Applies to all entities. If a size clause is present in the rep
3479 -- item chain for an entity then the attribute definition clause node
3480 -- for the size clause is returned. Otherwise Size_Clause returns Empty
3481 -- if no item is present. Usually this is only meaningful if the flag
3482 -- Has_Size_Clause is set. This is because when the representation item
3483 -- chain is copied for a derived type, it can inherit a size clause that
3484 -- is not applicable to the entity.
3486 -- Size_Depends_On_Discriminant (Flag177)
3487 -- Present in all entities for types and subtypes. Indicates that the
3488 -- size of the type depends on the value of one or more discriminants.
3489 -- Currently, this flag is only set in front end layout mode for arrays
3490 -- which have one or more bounds depending on a discriminant value.
3492 -- Size_Known_At_Compile_Time (Flag92)
3493 -- Present in all entities for types and subtypes. Indicates that the
3494 -- size of objects of the type is known at compile time. This flag is
3495 -- used to optimize some generated code sequences, and also to enable
3496 -- some error checks (e.g. disallowing component clauses on variable
3497 -- length objects). It is set conservatively (i.e. if it is True, the
3498 -- size is certainly known at compile time, if it is False, then the
3499 -- size may or may not be known at compile time, but the code will
3500 -- assume that it is not known).
3502 -- Small_Value (Ureal21)
3503 -- Present in fixed point types. Points to the universal real for the
3504 -- Small of the type, either as given in a representation clause, or
3505 -- as computed (as a power of two) by the compiler.
3507 -- Spec_Entity (Node19)
3508 -- Present in package body entities. Points to corresponding package
3509 -- spec entity. Also present in subprogram body parameters in the
3510 -- case where there is a separate spec, where this field references
3511 -- the corresponding parameter entities in the spec.
3513 -- Spec_PPC_List (Node24)
3514 -- Present in subprogram and generic subprogram entities. Points to a
3515 -- list of Precondition and Postcondition pragma nodes for preconditions
3516 -- and postconditions declared in the spec. The last pragma encountered
3517 -- is at the head of this list, so it is in reverse order of textual
3520 -- Storage_Size_Variable (Node15) [implementation base type only]
3521 -- Present in access types and task type entities. This flag is set
3522 -- if a valid and effective pragma Storage_Size applies to the base
3523 -- type. Points to the entity for a variable that is created to
3524 -- hold the value given in a Storage_Size pragma for an access
3525 -- collection or a task type. Note that in the access type case,
3526 -- this field is present only in the root type (since derived types
3527 -- share the same storage pool).
3529 -- Static_Elaboration_Desired (Flag77)
3530 -- Present in library-level packages. Set by the pragma of the same
3531 -- name, to indicate that static initialization must be attempted for
3532 -- all types declared in the package, and that a warning must be emitted
3533 -- for those types to which static initialization is not available.
3535 -- Static_Initialization (Node26)
3536 -- Present in initialization procedures for types whose objects can be
3537 -- initialized statically. The value of this attribute is a positional
3538 -- aggregate whose components are compile-time static values. Used
3539 -- when available in object declarations to eliminate the call to the
3540 -- initialization procedure, and to minimize elaboration code.
3542 -- Stored_Constraint (Elist23)
3543 -- Present in entities that can have discriminants (concurrent types
3544 -- subtypes, record types and subtypes, private types and subtypes,
3545 -- limited private types and subtypes and incomplete types). Points
3546 -- to an element list containing the expressions for each of the
3547 -- stored discriminants for the record (sub)type.
3549 -- Strict_Alignment (Flag145) [implementation base type only]
3550 -- Present in all type entities. Indicates that some containing part
3551 -- is either aliased or tagged. This prohibits packing the object
3552 -- tighter than its natural size and alignment.
3554 -- String_Literal_Length (Uint16)
3555 -- Present in string literal subtypes (which are created to correspond
3556 -- to string literals in the program). Contains the length of the string
3559 -- String_Literal_Low_Bound (Node15)
3560 -- Present in string literal subtypes (which are created to correspond
3561 -- to string literals in the program). Contains an expression whose
3562 -- value represents the low bound of the literal. This is a copy of
3563 -- the low bound of the applicable index constraint if there is one,
3564 -- or a copy of the low bound of the index base type if not.
3566 -- Suppress_Elaboration_Warnings (Flag148)
3567 -- Present in all entities, can be set only for subprogram entities and
3568 -- for variables. If this flag is set then Sem_Elab will not generate
3569 -- elaboration warnings for the subprogram or variable. Suppression of
3570 -- such warnings is automatic for subprograms for which elaboration
3571 -- checks are suppressed (without the need to set this flag), but the
3572 -- flag is also set for various internal entities (such as init procs)
3573 -- which are known not to generate any possible access before
3574 -- elaboration, and it is set on variables when a warning is given to
3575 -- avoid multiple elaboration warnings for the same variable.
3577 -- Suppress_Init_Proc (Flag105) [base type only]
3578 -- Present in all type entities. Set to suppress the generation of
3579 -- initialization procedures where they are known to be not needed.
3580 -- For example, the enumeration image table entity uses this flag.
3582 -- Suppress_Style_Checks (Flag165)
3583 -- Present in all entities. Suppresses any style checks specifically
3584 -- associated with the given entity if set.
3586 -- Suppress_Value_Tracking_On_Call (Flag217)
3587 -- Present in all entities. Set in a scope entity if value tracking is to
3588 -- be suppressed on any call within the scope. Used when an access to a
3589 -- local subprogram is computed, to deal with the possibility that this
3590 -- value may be passed around, and if used, may clobber a local variable.
3592 -- Task_Body_Procedure (Node25)
3593 -- Present in task types and subtypes. Points to the entity for the task
3594 -- task body procedure (as further described in Exp_Ch9, task bodies are
3595 -- expanded into procedures). A convenient function to retrieve this
3596 -- field is Sem_Util.Get_Task_Body_Procedure.
3598 -- The last sentence is odd??? Why not have Task_Body_Procedure go to the
3599 -- Underlying_Type of the Root_Type???
3601 -- Treat_As_Volatile (Flag41)
3602 -- Present in all type entities, and also in constants, components and
3603 -- variables. Set if this entity is to be treated as volatile for code
3604 -- generation purposes. Always set if Is_Volatile is set, but can also
3605 -- be set as a result of situations (such as address overlays) where
3606 -- the front end wishes to force volatile handling to inhibit aliasing
3607 -- optimization which might be legally ok, but is undesirable. Note
3608 -- that the back end always tests this flag rather than Is_Volatile.
3609 -- The front end tests Is_Volatile if it is concerned with legality
3610 -- checks associated with declared volatile variables, but if the test
3611 -- is for the purposes of suppressing optimizations, then the front
3612 -- end should test Treat_As_Volatile rather than Is_Volatile.
3614 -- Note: before testing Treat_As_Volatile, consider whether it would
3615 -- be more appropriate to use Exp_Util.Is_Volatile_Reference instead,
3616 -- which catches more cases of volatile references.
3618 -- Type_High_Bound (synthesized)
3619 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
3620 -- the high bound of a scalar type. The returned value is literal for a
3621 -- base type, but may be an expression in the case of scalar type with
3622 -- dynamic bounds. Note that in the case of a fixed point type, the high
3623 -- bound is in units of small, and is an integer.
3625 -- Type_Low_Bound (synthesized)
3626 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
3627 -- the low bound of a scalar type. The returned value is literal for a
3628 -- base type, but may be an expression in the case of scalar type with
3629 -- dynamic bounds. Note that in the case of a fixed point type, the low
3630 -- bound is in units of small, and is an integer.
3632 -- Underlying_Full_View (Node19)
3633 -- Present in private subtypes that are the completion of other private
3634 -- types, or in private types that are derived from private subtypes. If
3635 -- the full view of a private type T is derived from another private type
3636 -- with discriminants Td, the full view of T is also private, and there
3637 -- is no way to attach to it a further full view that would convey the
3638 -- structure of T to the back end. The Underlying_Full_ View is an
3639 -- attribute of the full view that is a subtype of Td with the same
3640 -- constraint as the declaration for T. The declaration for this subtype
3641 -- is built at the point of the declaration of T, either as completion,
3642 -- or as a subtype declaration where the base type is private and has a
3643 -- private completion. If Td is already constrained, then its full view
3644 -- can serve directly as the full view of T.
3646 -- Underlying_Record_View (Node28)
3647 -- Present in record types. Set for record types that are extensions of
3648 -- types with unknown discriminants, and also set for internally built
3649 -- underlying record views to reference its original record type. Record
3650 -- types that are extensions of types with unknown discriminants do not
3651 -- have a completion, but they cannot be used without having some
3652 -- discriminated view at hand. This view is a record type with the same
3653 -- structure, whose parent type is the full view of the parent in the
3654 -- original type extension.
3656 -- Underlying_Type (synthesized)
3657 -- Applies to all entities. This is the identity function except in the
3658 -- case where it is applied to an incomplete or private type, in which
3659 -- case it is the underlying type of the type declared by the completion,
3660 -- or Empty if the completion has not yet been encountered and analyzed.
3662 -- Note: the reason this attribute applies to all entities, and not just
3663 -- types, is to legitimize code where Underlying_Type is applied to an
3664 -- entity which may or may not be a type, with the intent that if it is a
3665 -- type, its underlying type is taken.
3667 -- Universal_Aliasing (Flag216) [base type only]
3668 -- Present in all type entities. Set to direct the back-end to avoid
3669 -- any optimizations based on type-based alias analysis for this type.
3670 -- Indicates that objects of this type can alias objects of any other
3671 -- types, which guarantees that any objects can be referenced through
3672 -- access types designating this type safely, whatever the actual type
3673 -- of these objects. In other words, the effect is as though access
3674 -- types designating this type were subject to No_Strict_Aliasing.
3676 -- Unset_Reference (Node16)
3677 -- Present in variables and out parameters. This is normally Empty. It
3678 -- is set to point to an identifier that represents a reference to the
3679 -- entity before any value has been set. Only the first such reference
3680 -- is identified. This field is used to generate a warning message if
3681 -- necessary (see Sem_Warn.Check_Unset_Reference).
3683 -- Used_As_Generic_Actual (Flag222)
3684 -- Present in all entities, set if the entity is used as an argument to
3685 -- a generic instantiation. Used to tune certain warning messages.
3687 -- Uses_Sec_Stack (Flag95)
3688 -- Present in scope entities (blocks,functions, procedures, tasks,
3689 -- entries). Set to True when secondary stack is used in this scope and
3690 -- must be released on exit unless Sec_Stack_Needed_For_Return is set.
3692 -- Vax_Float (Flag151) [base type only]
3693 -- Present in all type and subtype entities. Set only on the base type of
3694 -- float types with Vax format. The particular format is determined by
3695 -- the Digits_Value value which is 6,9,15 for F_Float, D_Float, G_Float.
3697 -- Warnings_Off (Flag96)
3698 -- Present in all entities. Set if a pragma Warnings (Off, entity-name)
3699 -- is used to suppress warnings for a given entity. It is also used by
3700 -- the compiler in some situations to kill spurious warnings. Note that
3701 -- clients should generally not test this flag directly, but instead
3702 -- use function Has_Warnings_Off.
3704 -- Warnings_Off_Used (Flag236)
3705 -- Present in all entities. Can only be set if Warnings_Off is set. If
3706 -- set indicates that a warning was suppressed by the Warnings_Off flag,
3707 -- and Unmodified/Unreferenced would not have suppressed the warning.
3709 -- Warnings_Off_Used_Unmodified (Flag237)
3710 -- Present in all entities. Can only be set if Warnings_Off is set and
3711 -- Has_Pragma_Unmodified is not set. If set indicates that a warning was
3712 -- suppressed by the Warnings_Off status but that pragma Unmodified
3713 -- would also have suppressed the warning.
3715 -- Warnings_Off_Used_Unreferenced (Flag238)
3716 -- Present in all entities. Can only be set if Warnings_Off is set and
3717 -- Has_Pragma_Unreferenced is not set. If set indicates that a warning
3718 -- was suppressed by the Warnings_Off status but that pragma Unreferenced
3719 -- would also have suppressed the warning.
3721 -- Was_Hidden (Flag196)
3722 -- Present in all entities. Used to save the value of the Is_Hidden
3723 -- attribute when the limited-view is installed (Ada 2005: AI-217).
3725 -- Wrapped_Entity (Node27)
3726 -- Present in functions and procedures which have been classified as
3727 -- Is_Primitive_Wrapper. Set to the entity being wrapped.
3733 -- The following entity kinds are introduced by the corresponding type
3737 -- E_General_Access_Type,
3738 -- E_Access_Subprogram_Type,
3739 -- E_Anonymous_Access_Subprogram_Type,
3740 -- E_Access_Protected_Subprogram_Type,
3741 -- E_Anonymous_Access_Protected_Subprogram_Type
3742 -- E_Anonymous_Access_Type.
3744 -- E_Access_Subtype is for an access subtype created by a subtype
3747 -- In addition, we define the kind E_Allocator_Type to label
3748 -- allocators. This is because special resolution rules apply to this
3749 -- construct. Eventually the constructs are labeled with the access
3750 -- type imposed by the context. Gigi should never see the type
3753 -- Similarly, the type E_Access_Attribute_Type is used as the initial
3754 -- kind associated with an access attribute. After resolution a specific
3755 -- access type will be established as determined by the context.
3757 -- Finally, the type Any_Access is used to label -null- during type
3758 -- resolution. Any_Access is also replaced by the context type after
3761 --------------------------------
3762 -- Classification of Entities --
3763 --------------------------------
3765 -- The classification of program entities which follows is a refinement of
3766 -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
3767 -- different type classes. Ada 95 entities include class wide types,
3768 -- protected types, subprogram types, generalized access types, generic
3769 -- formal derived types and generic formal packages.
3771 -- The order chosen for these kinds allows us to classify related entities
3772 -- so that they are contiguous. As a result, they do not appear in the
3773 -- exact same order as their order of first appearance in the LRM (For
3774 -- example, private types are listed before packages). The contiguity
3775 -- allows us to define useful subtypes (see below) such as type entities,
3776 -- overloaded entities, etc.
3778 -- Each entity (explicitly or implicitly declared) has a kind, which is
3779 -- a value of the following type:
3781 type Entity_Kind is (
3784 -- The initial Ekind value for a newly created entity. Also used as
3785 -- the Ekind for Standard_Void_Type, a type entity in Standard used
3786 -- as a dummy type for the return type of a procedure (the reason we
3787 -- create this type is to share the circuits for performing overload
3788 -- resolution on calls).

3796 -- protected objects.
3799 -- Constants created by an object declaration with a constant keyword

3866 -- Signed integer type, used for the anonymous base type of the
3867 -- integer subtype created by an integer type declaration.
3869 E_Signed_Integer_Subtype,
3870 -- Signed integer subtype, created by either an integer subtype or
3871 -- integer type declaration (in the latter case an integer type is
3872 -- created for the base type, and this is the first named subtype).
3874 E_Modular_Integer_Type,
3875 -- Modular integer type, used for the anonymous base type of the
3876 -- integer subtype created by a modular integer type declaration.
3878 E_Modular_Integer_Subtype,
3879 -- Modular integer subtype, created by either an modular subtype

3883 E_Ordinary_Fixed_Point_Type,
3884 -- Ordinary fixed type, used for the anonymous base type of the
3885 -- fixed subtype created by an ordinary fixed point type declaration.
3887 E_Ordinary_Fixed_Point_Subtype,
3888 -- Ordinary fixed point subtype, created by either an ordinary fixed
3889 -- point subtype or ordinary fixed point type declaration (in the
3890 -- latter case a fixed point type is created for the base type, and
3891 -- this is the first named subtype).
3893 E_Decimal_Fixed_Point_Type,
3894 -- Decimal fixed type, used for the anonymous base type of the decimal
3895 -- fixed subtype created by an ordinary fixed point type declaration.
3897 E_Decimal_Fixed_Point_Subtype,

3930 -- 'Unrestricted_Access and Unchecked_Access)
3933 -- A special internal type used to label allocators and attribute

4056 -- to declare a subtype of a protected type.
4063 -- The type of an exception created by an exception declaration
4066 -- This is the designated type of an Access_To_Subprogram. Has type
4067 -- and signature like a subprogram entity, so can appear in calls,
4068 -- which are resolved like regular calls, except that such an entity
4069 -- is not overloadable.
4071 ---------------------------
4072 -- Overloadable Entities --
4073 ---------------------------
4075 E_Enumeration_Literal,
4076 -- An enumeration literal, created by the use of the literal in an
4077 -- enumeration type definition.
4080 -- A function, created by a function declaration or a function body
4081 -- that acts as its own declaration.
4084 -- A predefined operator, appearing in Standard, or an implicitly
4085 -- defined concatenation operator created whenever an array is
4086 -- declared. We do not make normal derived operators explicit in
4087 -- the tree, but the concatenation operators are made explicit.
4090 -- A procedure, created by a procedure declaration or a procedure
4091 -- body that acts as its own declaration.
4094 -- An entry, created by an entry declaration in a task or protected
4097 --------------------
4098 -- Other Entities --
4099 --------------------
4102 -- An entry family, created by an entry family declaration in a
4103 -- task or protected type definition.
4106 -- A block identifier, created by an explicit or implicit label on
4107 -- a block or declare statement.
4109 E_Entry_Index_Parameter,
4110 -- An entry index parameter created by an entry index specification
4111 -- for the body of a protected entry family.
4114 -- An exception created by an exception declaration. The exception
4115 -- itself uses E_Exception for the Ekind, the implicit type that is
4116 -- created to represent its type uses the Ekind E_Exception_Type.
4119 -- A generic function. This is the entity for a generic function
4120 -- created by a generic subprogram declaration.
4122 E_Generic_Procedure,
4123 -- A generic function. This is the entity for a generic procedure
4124 -- created by a generic subprogram declaration.
4127 -- A generic package, this is the entity for a generic package created
4128 -- by a generic package declaration.
4131 -- The defining entity for a label. Note that this is created by the
4132 -- implicit label declaration, not the occurrence of the label itself,
4133 -- which is simply a direct name referring to the label.
4136 -- A loop identifier, created by an explicit or implicit label on a
4140 -- A dummy entity created for each return statement. Used to hold
4141 -- information about the return statement (what it applies to) and in
4142 -- rules checking. For example, a simple_return_statement that applies
4143 -- to an extended_return_statement cannot have an expression; this
4144 -- requires putting the E_Return_Statement entity for the
4145 -- extended_return_statement on the scope stack.
4148 -- A package, created by a package declaration
4151 -- A package body. This entity serves only limited functions, since
4152 -- most semantic analysis uses the package entity (E_Package). However
4153 -- there are some attributes that are significant for the body entity.
4154 -- For example, collection of exception handlers.
4157 -- A protected object, created by an object declaration that declares
4158 -- an object of a protected type.
4161 -- A protected body. This entity serves almost no function, since all
4162 -- semantic analysis uses the protected entity (E_Protected_Type)
4165 -- A task body. This entity serves almost no function, since all
4166 -- semantic analysis uses the protected entity (E_Task_Type).
4169 -- A subprogram body. Used when a subprogram has a separate declaration
4170 -- to represent the entity for the body. This entity serves almost no
4171 -- function, since all semantic analysis uses the subprogram entity
4172 -- for the declaration (E_Function or E_Procedure).

4182 -- The above entities are arranged so that they can be conveniently grouped
4183 -- into subtype ranges. Note that for each of the xxx_Kind ranges defined
4184 -- below, there is a corresponding Is_xxx (or for types, Is_xxx_Type)
4185 -- predicate which is to be used in preference to direct range tests using
4186 -- the subtype name. However, the subtype names are available for direct
4187 -- use, e.g. as choices in case statements.

5503 -- Since E_Void is the initial Ekind value of an entity when it is first

5508 -- well controlled, and needs cleaning up later. Meanwhile, the access
5509 -- procedures in the body of Einfo permit many, but not all, attributes
5510 -- to be applied to an E_Void entity, precisely so that this kind of
5511 -- pre-setting of attributes works. This is really a hole in the dynamic
5512 -- type checking, since there is no assurance that the eventual Ekind

5517 ---------------------------------
5518 -- Component_Alignment Control --
5519 ---------------------------------
5521 -- There are four types of alignment possible for array and record
5522 -- types, and a field in the type entities contains a value of the
5523 -- following type indicating which alignment choice applies. For full
5524 -- details of the meaning of these alignment types, see description
5525 -- of the Component_Alignment pragma
5527 type Component_Alignment_Kind is (
5528 Calign_Default, -- default alignment
5529 Calign_Component_Size, -- natural alignment for component size
5530 Calign_Component_Size_4, -- natural for size <= 4, 4 for size >= 4
5531 Calign_Storage_Unit); -- all components byte aligned
5537 -- In addition to attributes that are stored as plain data, other
5538 -- attributes are procedural, and require some small amount of
5539 -- computation. Of course, from the point of view of a user of this
5540 -- package, the distinction is not visible (even the field information
5541 -- provided below should be disregarded, as it is subject to change
5542 -- without notice!). A number of attributes appear as lists: lists of
5543 -- formals, lists of actuals, of discriminants, etc. For these, pairs
5544 -- of functions are defined, which take the form:
5546 -- function First_Thing (E : Enclosing_Construct) return Thing;
5547 -- function Next_Thing (T : Thing) return Thing;
5549 -- The end of iteration is always signaled by a value of Empty, so that
5550 -- loops over these chains invariably have the form:
5554 -- This := First_Thing (E);
5556 -- while Present (This) loop
5557 -- Do_Something_With (This);
5559 -- This := Next_Thing (This);
5562 -----------------------------------
5563 -- Handling of Check Suppression --
5564 -----------------------------------
5566 -- There are three ways that checks can be suppressed:
5568 -- 1. At the command line level
5569 -- 2. At the scope level.
5570 -- 3. At the entity level.
5572 -- See spec of Sem in sem.ads for details of the data structures used
5573 -- to keep track of these various methods for suppressing checks.
5575 -------------------------------
5576 -- Handling of Discriminants --
5577 -------------------------------
5579 -- During semantic processing, discriminants are separate entities which
5580 -- reflect the semantic properties and allowed usage of discriminants in
5583 -- In the case of discriminants used as bounds, the references are handled
5584 -- directly, since special processing is needed in any case. However, there
5585 -- are two circumstances in which discriminants are referenced in a quite
5586 -- general manner, like any other variables:
5588 -- In initialization expressions for records. Note that the expressions
5589 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline
5590 -- pragmas are effectively in this category, since these pragmas are
5591 -- converted to initialized record fields in the Corresponding_Record_
5594 -- In task and protected bodies, where the discriminant values may be
5595 -- referenced freely within these bodies. Discriminants can also appear
5596 -- in bounds of entry families and in defaults of operations.
5598 -- In both these cases, the discriminants must be treated essentially as
5599 -- objects. The following approach is used to simplify and minimize the
5600 -- special processing that is required.
5602 -- When a record type with discriminants is analyzed, semantic processing
5603 -- creates the entities for the discriminants. It also creates additional
5604 -- sets of entities called discriminals, one for each of the discriminants,
5605 -- and the Discriminal field of the discriminant entity points to this
5606 -- additional entity, which is initially created as an uninitialized
5609 -- During expansion of expressions, any discriminant reference is replaced
5610 -- by a reference to the corresponding discriminal. When the initialization
5611 -- procedure for the record is created (there will always be one, since
5612 -- discriminants are present, see Exp_Ch3 for further details), the
5613 -- discriminals are used as the entities for the formal parameters of
5614 -- this initialization procedure. The references to these discriminants
5615 -- have already been replaced by references to these discriminals, which
5616 -- are now the formal parameters corresponding to the required objects.
5618 -- In the case of a task or protected body, the semantics similarly creates
5619 -- a set of discriminals for the discriminants of the task or protected
5620 -- type. When the procedure is created for the task body, the parameter
5621 -- passed in is a reference to the task value type, which contains the
5622 -- required discriminant values. The expander creates a set of declarations
5625 -- discr_nameD : constant discr_type renames _task.discr_name;
5627 -- where discr_nameD is the discriminal entity referenced by the task
5628 -- discriminant, and _task is the task value passed in as the parameter.
5629 -- Again, any references to discriminants in the task body have been
5630 -- replaced by the discriminal reference, which is now an object that
5631 -- contains the required value.
5633 -- This approach for tasks means that two sets of discriminals are needed
5634 -- for a task type, one for the initialization procedure, and one for the
5635 -- task body. This works out nicely, since the semantics allocates one set
5636 -- for the task itself, and one set for the corresponding record.
5638 -- The one bit of trickiness arises in making sure that the right set of
5639 -- discriminals is used at the right time. First the task definition is
5640 -- processed. Any references to discriminants here are replaced by the
5641 -- corresponding *task* discriminals (the record type doesn't even exist
5642 -- yet, since it is constructed as part of the expansion of the task
5643 -- declaration, which happens after the semantic processing of the task
5644 -- definition). The discriminants to be used for the corresponding record
5645 -- are created at the same time as the other discriminals, and held in the
5646 -- CR_Discriminant field of the discriminant. A use of the discriminant in
5647 -- a bound for an entry family is replaced with the CR_Discriminant because
5648 -- it controls the bound of the entry queue array which is a component of
5649 -- the corresponding record.
5651 -- Just before the record initialization routine is constructed, the
5652 -- expander exchanges the task and record discriminals. This has two
5653 -- effects. First the generation of the record initialization routine
5654 -- uses the discriminals that are now on the record, which is the set
5655 -- that used to be on the task, which is what we want.
5657 -- Second, a new set of (so far unused) discriminals is now on the task
5658 -- discriminants, and it is this set that will be used for expanding the
5659 -- task body, and also for the discriminal declarations at the start of
5662 ---------------------------------------------------
5663 -- Handling of private data in protected objects --
5664 ---------------------------------------------------
5666 -- Private components in protected types pose problems similar to those
5667 -- of discriminants. Private data is visible and can be directly referenced
5668 -- from protected bodies. However, when protected entries and subprograms
5669 -- are expanded into corresponding bodies and barrier functions, private
5670 -- components lose their original context and visibility.
5672 -- To remedy this side effect of expansion, private components are expanded
5673 -- into renamings called "privals", by analogy with "discriminals".
5675 -- private_comp : comp_type renames _object.private_comp;
5677 -- Prival declarations are inserted during the analysis of subprogram and
5678 -- entry bodies to ensure proper visibility for any subsequent expansion.
5679 -- _Object is the formal parameter of the generated corresponding body or
5680 -- a local renaming which denotes the protected object obtained from entry
5681 -- parameter _O. Privals receive minimal decoration upon creation and are
5682 -- categorized as either E_Variable for the general case or E_Constant when
5683 -- they appear in functions.
5685 -- Along with the local declarations, each private component carries a
5686 -- placeholder which references the prival entity in the current body. This
5687 -- form of indirection is used to resolve name clashes of privals and other
5688 -- locally visible entities such as parameters, local objects, entry family
5689 -- indexes or identifiers used in the barrier condition.
5691 -- When analyzing the statements of a protected subprogram or entry, any
5692 -- reference to a private component must resolve to the locally declared
5693 -- prival through normal visibility. In case of name conflicts (the cases
5694 -- above), the prival is marked as hidden and acts as a weakly declared
5695 -- entity. As a result, the reference points to the correct entity. When a
5696 -- private component is denoted by an expanded name (prot_type.comp for
5697 -- example), the expansion mechanism uses the placeholder of the component
5698 -- to correct the Entity and Etype of the reference.
5704 -- The following type synonyms are used to tidy up the function and
5705 -- procedure declarations that follow, and also to make it possible to meet
5706 -- the requirement for the XEINFO utility that all function specs must fit
5707 -- on a single source line.

6223 -- These predicates test the setting of the indicated attribute. If the
6224 -- value has been set, then Known is True, and Unknown is False. If no
6225 -- value is set, then Known is False and Unknown is True. The Known_Static
6226 -- predicate is true only if the value is set (Known) and is set to a
6227 -- compile time known value. Note that in the case of Alignment and
6228 -- Normalized_First_Bit, dynamic values are not possible, so we do not
6229 -- need a separate Known_Static calls in these cases. The not set (unknown
6230 -- values are as follows:
6232 -- Alignment Uint_0 or No_Uint
6233 -- Component_Size Uint_0 or No_Uint
6234 -- Component_Bit_Offset No_Uint
6235 -- Digits_Value Uint_0 or No_Uint
6236 -- Esize Uint_0 or No_Uint
6237 -- Normalized_First_Bit No_Uint
6238 -- Normalized_Position No_Uint
6239 -- Normalized_Position_Max No_Uint
6240 -- RM_Size Uint_0 or No_Uint
6242 -- It would be cleaner to use No_Uint in all these cases, but historically
6243 -- we chose to use Uint_0 at first, and the change over will take time ???
6244 -- This is particularly true for the RM_Size field, where a value of zero
6245 -- is legitimate. We deal with this by a nasty kludge that knows that the
6246 -- value is always known static for discrete types (and no other types can
6247 -- have an RM_Size value of zero).
6249 -- In two cases, Known_Static_Esize and Known_Static_RM_Size, there is one
6250 -- more consideration, which is that we always return False for generic
6251 -- types. Within a template, the size can look known, because of the fake
6252 -- size values we put in template types, but they are not really known and
6253 -- anyone testing if they are known within the template should get False as
6254 -- a result to prevent incorrect assumptions.
