42 -- This package defines the annotations to the abstract syntax tree that
43 -- are needed to support semantic processing of an Ada compilation.
45 -- Note that after editing this spec and the corresponding body it is
46 -- required to run ceinfo to check the consistentcy of spec and body.
47 -- See ceinfo.adb for more information about the checks made.
49 -- These annotations are for the most part attributes of declared entities,
50 -- and they correspond to conventional symbol table information. Other
51 -- attributes include sets of meanings for overloaded names, possible
52 -- types for overloaded expressions, flags to indicate deferred constants,
53 -- incomplete types, etc. These attributes are stored in available fields
54 -- in tree nodes (i.e. fields not used by the parser, as defined by the
55 -- Sinfo package specification), and accessed by means of a set of
56 -- subprograms which define an abstract interface.
58 -- There are two kinds of semantic information
60 -- First, the tree nodes with the following Nkind values:
62 -- N_Defining_Identifier
63 -- N_Defining_Character_Literal
64 -- N_Defining_Operator_Symbol
66 -- are called Entities, and constitute the information that would often
67 -- be stored separately in a symbol table. These nodes are all extended
68 -- to provide extra space, and contain fields which depend on the entity
69 -- kind, as defined by the contents of the Ekind field. The use of the
70 -- Ekind field, and the associated fields in the entity, are defined
71 -- in this package, as are the access functions to these fields.
73 -- Second, in some cases semantic information is stored directly in other
74 -- kinds of nodes, e.g. the Etype field, used to indicate the type of an
75 -- expression. The access functions to these fields are defined in the
76 -- Sinfo package, but their full documentation is to be found in
77 -- the Einfo package specification.
79 -- Declaration processing places information in the nodes of their defining
80 -- identifiers. Name resolution places in all other occurrences of an
81 -- identifier a pointer to the corresponding defining occurrence.
83 --------------------------------
84 -- The XEINFO Utility Program --
85 --------------------------------
87 -- XEINFO is a utility program which automatically produces a C header file,
88 -- einfo.h from the spec and body of package Einfo. It reads the input
89 -- files einfo.ads and einfo.adb and produces the output file einfo.h.
90 -- XEINFO is run automatically by the build scripts when you do a full
93 -- In order for this utility program to operate correctly, the form of the
94 -- einfo.ads and einfo.adb files must meet certain requirements and be laid
95 -- out in a specific manner.
97 -- The general form of einfo.ads is as follows:
99 -- type declaration for type Entity_Kind
100 -- subtype declarations declaring subranges of Entity_Kind
101 -- subtype declarations declaring synonyms for some standard types
102 -- function specs for attributes
104 -- pragma Inline declarations
106 -- This order must be observed. There are no restrictions on the procedures,
107 -- since the C header file only includes functions (Gigi is not allowed to
108 -- modify the generated tree). However, functions are required to have headers
109 -- that fit on a single line.
111 -- XEINFO reads and processes the function specs and the pragma Inlines. For
112 -- functions that are declared as inlined, XEINFO reads the corresponding body
113 -- from einfo.adb, and processes it into C code. This results in some strict
114 -- restrictions on which functions can be inlined:
116 -- The function spec must be on a single line
118 -- There can only be a single statement, contained on a single line,
119 -- not counting any pragma Assert statements.
121 -- This single statement must either be a function call with simple,
122 -- single token arguments, or it must be a membership test of the form
123 -- a in b, where a and b are single tokens.
125 -- For functions that are not inlined, there is no restriction on the body,
126 -- and XEINFO generates a direct reference in the C header file which allows
127 -- the C code in Gigi to directly call the corresponding Ada body.

130 -- Handling of Type'Size Values --
131 ----------------------------------
133 -- The Ada 95 RM contains some rather peculiar (to us!) rules on the value
134 -- of type'Size (see RM 13.3(55)). We have found that attempting to use
135 -- these RM Size values generally, and in particular for determining the
136 -- default size of objects, creates chaos, and major incompatibilies in
139 -- We proceed as follows, for discrete and fixed-point subtypes, we have
140 -- two separate sizes for each subtype:
142 -- The Object_Size, which is used for determining the default size of
143 -- objects and components. This size value can be referred to using the
144 -- Object_Size attribute. The phrase "is used" here means that it is
145 -- the basis of the determination of the size. The backend is free to
146 -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
147 -- character might be stored in 32 bits on a machine with no efficient
148 -- byte access instructions such as the Alpha.
150 -- The default rules for the value of Object_Size for fixed-point and
151 -- discrete types are as follows:
153 -- The Object_Size for base subtypes reflect the natural hardware
154 -- size in bits (see Ttypes and Cstand for integer types). For
155 -- enumeration and fixed-point base subtypes have 8. 16. 32 or 64
156 -- bits for this size, depending on the range of values to be stored.
158 -- The Object_Size of a subtype is the same as the Object_Size of
159 -- the subtype from which it is obtained.
161 -- The Object_Size of a derived base type is copied from the parent
162 -- base type, and the Object_Size of a derived first subtype is copied
163 -- from the parent first subtype.
165 -- The Value_Size which is the number of bits required to store a value
166 -- of the type. This size can be referred to using the Value_Size
167 -- attribute. This value is used to determine how tightly to pack
168 -- records or arrays with components of this type, and also affects
169 -- the semantics of unchecked conversion (unchecked conversions where
170 -- the Value_Size values differ generate a warning, and are potentially
171 -- target dependent).
173 -- The default rule for the value of Value_Size are as follows:
175 -- The Value_Size for a base subtype is the minimum number of bits
176 -- required to store all values of the type (including the sign bit
177 -- only if negative values are possible).
179 -- If a subtype statically matches the first subtype, then it has
180 -- by default the same Value_Size as the first subtype. This is a
181 -- consequence of RM 13.1(14) ("if two subtypes statically match,
182 -- then their subtype-specific aspects are the same".)
184 -- All other subtypes have a Value_Size corresponding to the minimum
185 -- number of bits required to store all values of the subtype. For
186 -- dynamic bounds, it is assumed that the value can range down or up
187 -- to the corresponding bound of the ancestor
189 -- The RM defined attribute Size corresponds to the Value_Size attribute
191 -- The Size attribute may be defined for a first-named subtype. This sets
192 -- the Value_Size of the first-named subtype to the given value, and the
193 -- Object_Size of this first-named subtype to the given value padded up
194 -- to an appropriate boundary. It is a consequence of the default rules
195 -- above that this Object_Size will apply to all further subtypes. On the
196 -- otyher hand, Value_Size is affected only for the first subtype, any
197 -- dynamic subtypes obtained from it directly, and any statically matching
198 -- subtypes. The Value_Size of any other static subtypes is not affected.
200 -- Value_Size and Object_Size may be explicitly set for any subtype using
201 -- an attribute definition clause. Note that the use of these attributes
202 -- can cause the RM 13.1(14) rule to be violated. If two access types
203 -- reference aliased objects whose subtypes have differing Object_Size
204 -- values as a result of explicit attribute definition clauses, then it
205 -- is erroneous to convert from one access subtype to the other.
207 -- At the implementation level, Esize stores the Object_Size and the
208 -- RM_Size field stores the Value_Size (and hence the value of the
209 -- Size attribute, which, as noted above, is equivalent to Value_Size).
211 -- To get a feel for the difference, consider the following examples (note
212 -- that in each case the base is short_short_integer with a size of 8):
214 -- Object_Size Value_Size
216 -- type x1 is range 0..5; 8 3
218 -- type x2 is range 0..5;
219 -- for x2'size use 12; 12 12
221 -- subtype x3 is x2 range 0 .. 3; 12 2
223 -- subtype x4 is x2'base range 0 .. 10; 8 4
225 -- subtype x5 is x2 range 0 .. dynamic; 12 (7)
227 -- subtype x6 is x2'base range 0 .. dynamic; 8 (7)
229 -- Note: the entries marked (7) are not actually specified by the Ada 95 RM,
230 -- but it seems in the spirit of the RM rules to allocate the minimum number
231 -- of bits known to be large enough to hold the given range of values.
233 -- So far, so good, but GNAT has to obey the RM rules, so the question is
234 -- under what conditions must the RM Size be used. The following is a list
235 -- of the occasions on which the RM Size must be used:
237 -- Component size for packed arrays or records
238 -- Value of the attribute Size for a type
239 -- Warning about sizes not matching for unchecked conversion
241 -- The RM_Size field keeps track of the RM Size as needed in these
244 -- For types other than discrete and fixed-point types, the Object_Size
245 -- and Value_Size are the same (and equivalent to the RM attribute Size).
246 -- Only Size may be specified for such types.
248 -----------------------
249 -- Entity Attributes --
250 -----------------------
252 -- This section contains a complete list of the attributes that are defined
253 -- on entities. Some attributes apply to all entities, others only to certain
254 -- kinds of entities. In the latter case the attribute should only be set or
255 -- accessed if the Ekind field indicates an appropriate entity.
257 -- There are two kinds of attributes that apply to entities, stored and
258 -- synthesized. Stored attributes correspond to a field or flag in the entity
259 -- itself. Such attributes are identified in the table below by giving the
260 -- field or flag in the attribute that is used to hold the attribute value.
261 -- Synthesized attributes are not stored directly, but are rather computed as
262 -- needed from other attributes, or from information in the tree. These are
263 -- marked "synthesized" in the table below. The stored attributes have both
264 -- access functions and set procedures to set the corresponding values, while
265 -- synthesized attributes have only access functions.
267 -- Note: in the case of Node, Uint, or Elist fields, there are cases where
268 -- the same physical field is used for different purposes in different
269 -- entities, so these access functions should only be referenced for the
270 -- class of entities in which they are defined as being present. Flags are
271 -- not overlapped in this way, but nevertheless as a matter of style and
272 -- abstraction (which may or may not be checked by assertions in the body),
273 -- this restriction should be observed for flag fields as well.
275 -- Note: certain of the attributes on types apply only to base types, and
276 -- are so noted by the notation [base type only]. These are cases where the
277 -- attribute of any subtype is the same as the attribute of the base type.
278 -- The attribute can be referenced on a subtype (and automatically retrieves
279 -- the value from the base type). However, it is an error to try to set the
280 -- attribute on other than the base type, and if assertions are enabled,
281 -- an attempt to set the attribute on a subtype will raise an assert error.
283 -- Other attributes are noted as applying the implementation base type only.
284 -- These are representation attributes which must always apply to a full
285 -- non-private type, and where the attributes are always on the full type.
286 -- The attribute can be referenced on a subtype (and automatically retries
287 -- the value from the implementation base type). However, it is an error
288 -- to try to set the attribute on other than the implementation base type,
289 -- and if assertions are enabled, an attempt to set the attribute on a
290 -- subtype will raise an assert error.
292 -- Abstract_Interfaces (Elist25)
293 -- Present in record types and subtypes. List of abstract interfaces
294 -- implemented by a tagged type that are not already implemented by the
295 -- ancestors (Ada 2005: AI-251).
297 -- Abstract_Interface_Alias (Node25)
298 -- Present in subprograms that cover a primitive operation of an abstract
299 -- interface type. Can be set only if the Is_Hidden flag is also set,
300 -- since such entities are always hidden. Points to its associated
301 -- interface subprogram. It is used to register the subprogram in
302 -- secondary dispatch table of the interface (Ada 2005: AI-251).
304 -- Accept_Address (Elist21)
305 -- Present in entries. If an accept has a statement sequence, then an
306 -- address variable is created, which is used to hold the address of the
307 -- parameters, as passed by the runtime. Accept_Address holds an element
308 -- list which represents a stack of entities for these address variables.
309 -- The current entry is the top of the stack, which is the last element
310 -- on the list. A stack is required to handle the case of nested select
311 -- statements referencing the same entry.
313 -- Actual_Subtype (Node17)
314 -- Present in variables, constants, and formal parameters. This is the
315 -- subtype imposed by the value of the object, as opposed to its nominal
316 -- subtype, which is imposed by the declaration. The actual subtype
317 -- differs from the nominal one when the latter is indefinite (as in the
318 -- case of an unconstrained formal parameter, or a variable declared
319 -- with an unconstrained type and an initial value). The nominal subtype
320 -- is the Etype entry for the entity. The Actual_Subtype field is set
321 -- only if the actual subtype differs from the nominal subtype. If the
322 -- actual and nominal subtypes are the same, then the Actual_Subtype
323 -- field is Empty, and Etype indicates both types.
325 -- For objects, the Actual_Subtype is set only if this is a discriminated
326 -- type. For arrays, the bounds of the expression are obtained and the
327 -- Etype of the object is directly the constrained subtype. This is
328 -- rather irregular, and the semantic checks that depend on the nominal
329 -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
331 -- Access_Disp_Table (Elist16) [implementation base type only]
332 -- Present in record type entities. For a tagged type, points to the
333 -- dispatch tables associated with the tagged type; the last entity of
334 -- this list is an access type declaration used to expand dispatching
335 -- calls through the primary dispatch table. For a non-tagged record,
338 -- Address_Clause (synthesized)
339 -- Applies to entries, objects and subprograms. Set if an address clause
340 -- is present which references the object or subprogram and points to
341 -- the N_Attribute_Definition_Clause node. Empty if no Address clause.
342 -- The expression in the address clause is always a constant that is
343 -- defined before the entity to which the address clause applies.
344 -- Note: Gigi references this field in E_Task_Type entities???
346 -- Address_Taken (Flag104)
347 -- Present in all entities. Set if the Address or Unrestricted_Access
348 -- attribute is applied directly to the entity, i.e. the entity is the
349 -- entity of the prefix of the attribute reference. Used by Gigi to
350 -- make sure that the address can be meaningfully taken.
353 -- Present in overloaded entities (literals, subprograms, entries) and
354 -- subprograms that cover a primitive operation of an abstract interface
355 -- (that is, subprograms with the Abstract_Interface_Alias attribute).
356 -- In case of overloaded entities it points to the parent subprogram of
357 -- a derived subprogram. In case of abstract interface subprograms it
358 -- points to the subprogram that covers the abstract interface primitive.
359 -- Also used for a subprogram renaming, where it points to the renamed
360 -- subprogram. Always empty for entries.
362 -- Alignment (Uint14)
363 -- Present in entities for types and also in constants, variables
364 -- (including exceptions where it refers to the static data allocated for
365 -- an exception), loop parameters, and formal parameters. This indicates
366 -- the desired alignment for a type, or the actual alignment for an
367 -- object. A value of zero (Uint_0) indicates that the alignment has not
368 -- been set yet. The alignment can be set by an explicit alignment
369 -- clause, or set by the front-end in package Layout, or set by the
370 -- back-end as part of the back end back-annotation process. The
371 -- alignment field is also present in E_Exception entities, but there it
372 -- is used only by the back-end for back annotation.
374 -- Alignment_Clause (synthesized)
375 -- Applies to all entities for types and objects. If an alignment
376 -- attribute definition clause is present for the entity, then this
377 -- function returns the N_Attribute_Definition clause that specifies the
378 -- alignment. If no alignment clause applies to the type, then the call
379 -- to this function returns Empty. Note that the call can return a
380 -- non-Empty value even if Has_Alignment_Clause is not set (happens with
381 -- subtype and derived type declarations). Note also that a record
382 -- definition clause with an (obsolescent) mod clause is converted
383 -- into an attribute definition clause for this purpose.
385 -- Ancestor_Subtype (synthesized)
386 -- Applies to all type and subtype entities. If the argument is a
387 -- subtype then it returns the subtype or type from which the subtype
388 -- was obtained, otherwise it returns Empty.
390 -- Available_View (synthesized)
391 -- Applies to types that have the With_Type flag set. Returns the
392 -- non-limited view of the type, if available, otherwise the type
393 -- itself. For class-wide types, there is no direct link in the tree,
394 -- so we have to retrieve the class-wide type of the non-limited view
397 -- Associated_Formal_Package (Node12)
398 -- Present in packages that are the actuals of formal_packages. Points
399 -- to the entity in the declaration for the formal package.
401 -- Associated_Node_For_Itype (Node8)
402 -- Present in all type and subtype entities. Set non-Empty only for
403 -- Itypes. Set to point to the associated node for the Itype, i.e.
404 -- the node whose elaboration generated the Itype. This is used for
405 -- copying trees, to determine whether or not to copy an Itype, and
406 -- also for accessibility checks on anonymous access types. This
407 -- node is typically an object declaration, component declaration,
408 -- type or subtype declaration. For an access discriminant in a type
409 -- declaration, the associated_node_for_itype is the discriminant
410 -- specification. For an access parameter it is the enclosing subprogram
413 -- Associated_Storage_Pool (Node22) [root type only]
414 -- Present in simple and general access type entities. References the
415 -- storage pool to be used for the corresponding collection. A value of
416 -- Empty means that the default pool is to be used. This is present
417 -- only in the root type, since derived types must have the same pool
418 -- as the parent type.
420 -- Associated_Final_Chain (Node23)
421 -- Present in simple and general access type entities. References the
422 -- List_Controller object that holds the finalization chain on which
423 -- are attached dynamically allocated objects referenced by the access
424 -- type. Empty when the access type cannot reference a controlled object.
426 -- Barrier_Function (Node12)
427 -- Present in protected entries and entry families. This is the
428 -- subprogram declaration for the body of the function that returns
429 -- the value of the entry barrier.
431 -- Base_Type (synthesized)
432 -- Applies to all type entities. Returns the base type of a type or
433 -- subtype. The base type of a type is the type itself. The base type
434 -- of a subtype is the type that it constrains (which is always a type
435 -- entity, not some other subtype). Note that in the case of a subtype
436 -- of a private type, it is possible for the base type attribute to
437 -- return a private type, even if the subtype to which it applies is
438 -- non-private. See also Implementation_Base_Type. Note: it is allowed
439 -- to apply Base_Type to other than a type, in which case it simply
440 -- returns the entity unchanged.
442 -- Block_Node (Node11)
443 -- Present in block entities. Points to the identifier in the
444 -- Block_Statement itself. Used when retrieving the block construct
445 -- for finalization purposes, The block entity has an implicit label
446 -- declaration in the enclosing declarative part, and has otherwise
447 -- no direct connection in the tree with the block statement. The
448 -- link is to the identifier (which is an occurence of the entity)
449 -- and not to the block_statement itself, because the statement may
450 -- be rewritten, e.g. in the process of removing dead code.
452 -- Body_Entity (Node19)
453 -- Present in package and generic package entities, points to the
454 -- corresponding package body entity if one is present.
456 -- Body_Needed_For_SAL (Flag40)
457 -- Present in package and subprogram entities that are compilation
458 -- units. Indicates that the source for the body must be included
459 -- when the unit is part of a standalone library.
461 -- C_Pass_By_Copy (Flag125) [implementation base type only]
462 -- Present in record types. Set if a pragma Convention for the record
463 -- type specifies convention C_Pass_By_Copy. This convention name is
464 -- treated as identical in all respects to convention C, except that
465 -- if it is specified for a record type, then the C_Pass_By_Copy flag
466 -- is set, and if a foreign convention subprogram has a formal of the
467 -- corresponding type, then the parameter passing mechanism will be
468 -- set to By_Copy (unless specifically overridden by an Import or
471 -- Can_Never_Be_Null (Flag38)
472 -- This flag is present in all entities, but can only be set in an object
473 -- which can never have a null value. This is set True for constant
474 -- access values initialized to a non-null value. This is also True for
475 -- all access parameters in Ada 83 and Ada 95 modes, and for access
476 -- parameters that explicily exlude null in Ada 2005.
478 -- This is used to avoid unnecessary resetting of the Is_Known_Non_Null
479 -- flag for such entities. In Ada 2005 mode, this is also used when
480 -- determining subtype conformance of subprogram profiles to ensure
481 -- that two formals have the same null-exclusion status.
483 -- ??? This is also set on some access types, eg the Etype of the
484 -- anonymous access type of a controlling formal.
487 -- Present in all entities. This field contains an entry into the names
488 -- table that has the character string of the identifier, character
489 -- literal or operator symbol. See Namet for further details. Note that
490 -- throughout the processing of the front end, this name is the simple
491 -- unqualified name. However, just before gigi is called, a call is made
492 -- to Qualify_All_Entity_Names. This causes entity names to be qualified
493 -- using the encoding described in exp_dbug.ads, and from that point on
494 -- (including post gigi steps such as cross-reference generation), the
495 -- entities will contain the encoded qualified names.
497 -- Checks_May_Be_Suppressed (Flag31)
498 -- Present in all entities. Set if a pragma Suppress or Unsuppress
499 -- mentions the entity specifically in the second argument. If this
500 -- flag is set the the Global_Entity_Suppress and Local_Entity_Suppress
501 -- tables must be consulted to determine if the is actually an active
502 -- Suppress or Unsuppress pragma that applies to the entity.
504 -- Class_Wide_Type (Node9)
505 -- Present in all type entities. For a tagged type or subtype, returns
506 -- the corresponding implicitly declared class-wide type. Set to Empty
507 -- for non-tagged types.
509 -- Cloned_Subtype (Node16)
510 -- Present in E_Record_Subtype and E_Class_Wide_Subtype entities.
511 -- Each such entity can either have a Discriminant_Constraint, in
512 -- which case it represents a distinct type from the base type (and
513 -- will have a list of components and discrimants in the list headed by
514 -- First_Entity) or else no such constraint, in which case it will be a
515 -- copy of the base type.
517 -- o Each element of the list in First_Entity is copied from the base
518 -- type; in that case, this field is Empty.
520 -- o The list in First_Entity is shared with the base type; in that
521 -- case, this field points to that entity.
523 -- A record or classwide subtype may also be a copy of some other
524 -- subtype and share the entities in the First_Entity with that subtype.
525 -- In that case, this field points to that subtype.
527 -- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
528 -- this field. Note that this field ONLY appears in subtype entries, not
529 -- in type entries, it is not present, and it is an error to reference
530 -- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
533 -- This flag appears on all nodes, including entities, and indicates
534 -- that the node was created by the scanner or parser from the original
535 -- source. Thus for entities, it indicates that the entity is defined
536 -- in the original source program.
538 -- Component_Alignment (special field) [base type only]
539 -- Present in array and record entities. Contains a value of type
540 -- Component_Alignment_Kind indicating the alignment of components.
541 -- Set to Calign_Default normally, but can be overridden by use of
542 -- the Component_Alignment pragma. Note: this field is currently
543 -- stored in a non-standard way, see body for details.
545 -- Component_Bit_Offset (Uint11)
546 -- Present in record components (E_Component, E_Discriminant) if a
547 -- component clause applies to the component. First bit position of
548 -- given component, computed from the first bit and position values
549 -- given in the component clause. A value of No_Uint means that the
550 -- value is not yet known. The value can be set by the appearence of
551 -- an explicit component clause in a record representation clause,
552 -- or it can be set by the front-end in package Layout, or it can be
553 -- set by the backend. By the time backend processing is completed,
554 -- this field is always set. A negative value is used to represent
555 -- a value which is not known at compile time, and must be computed
556 -- at run-time (this happens if fields of a record have variable
557 -- lengths). See package Layout for details of these values.
559 -- Note: this field is obsolescent, to be eventually replaced entirely
560 -- by Normalized_First_Bit and Normalized_Position, but for the moment,
561 -- gigi is still using (and back annotating) this field, and gigi does
562 -- not know about the new fields. For the front end layout case, the
563 -- Component_Bit_Offset field is only set if it is static, and otherwise
564 -- the new Normalized_First_Bit and Normalized_Position fields are used.
566 -- Component_Clause (Node13)
567 -- Present in record components and discriminants. If a record
568 -- representation clause is present for the corresponding record
569 -- type a that specifies a position for the component, then the
570 -- Component_Clause field of the E_Component entity points to the
571 -- N_Component_Clause node. Set to Empty if no record representation
572 -- clause was present, or if there was no specification for this
575 -- Component_Size (Uint22) [implementation base type only]
576 -- Present in array types. It contains the component size value for
577 -- the array. A value of No_Uint means that the value is not yet set.
578 -- The value can be set by the use of a component size clause, or
579 -- by the front end in package Layout, or by the backend. A negative
580 -- value is used to represent a value which is not known at compile
581 -- time, and must be computed at run-time (this happens if the type
582 -- of the component has a variable length size). See package Layout
583 -- for details of these values.
585 -- Component_Type (Node20) [implementation base type only]
586 -- Present in array types and string types. References component type.
588 -- Constant_Value (synthesized)
589 -- Applies to variables, constants, named integers, and named reals.
590 -- Obtains the initialization expression for the entity. Will return
591 -- Empty for for a deferred constant whose full view is not available
592 -- or in some other cases of internal entities, which cannot be treated
593 -- as constants from the point of view of constant folding. Empty is
594 -- also returned for variables with no initialization expression.
596 -- Corresponding_Concurrent_Type (Node18)
597 -- Present in record types that are constructed by the expander to
598 -- represent task and protected types (Is_Concurrent_Record_Type flag
599 -- set True). Points to the entity for the corresponding task type or
602 -- Corresponding_Discriminant (Node19)
603 -- Present in discriminants of a derived type, when the discriminant is
604 -- used to constrain a discriminant of the parent type. Points to the
605 -- corresponding discriminant in the parent type. Otherwise it is Empty.
607 -- Corresponding_Equality (Node13)
608 -- Present in function entities for implicit inequality operators.
609 -- Denotes the explicit or derived equality operation that creates
610 -- the implicit inequality. Note that this field is not present in
611 -- other function entities, only in implicit inequality routines,
612 -- where Comes_From_Source is always False.
614 -- Corresponding_Record_Type (Node18)
615 -- Present in protected and task types and subtypes. References the
616 -- entity for the corresponding record type constructed by the expander
617 -- (see Exp_Ch9). This type is used to represent values of the task type.
619 -- Corresponding_Remote_Type (Node22)
620 -- Present in record types that describe the fat pointer structure for
621 -- Remote_Access_To_Subrogram types. References the original access type.
623 -- CR_Discriminant (Node23)
624 -- Present in discriminants of concurrent types. Denotes the homologous
625 -- discriminant of the corresponding record type. The CR_Discriminant is
626 -- created at the same time as the discriminal, and used to replace
627 -- occurrences of the discriminant within the type declaration.
629 -- Current_Use_Clause (Node25)
630 -- Present in packages. Indicates the use clause currently in scope
631 -- that makes the package use_visible. Used to detect redundant use
632 -- clauses for the same package.
634 -- Current_Value (Node9)
635 -- Present in all object entities. Set in E_Variable, E_Constant, formal
636 -- parameters and E_Loop_Parameter entities if we have trackable current
637 -- values. Set non-Empty if the (constant) current value of the variable
638 -- is known, This value is valid only for references from the same
639 -- sequential scope as the entity. The sequential scope of an entity
640 -- includes the immediate scope and any contained scopes that are package
641 -- specs, package bodies, blocks (at any nesting level) or statement
642 -- sequences in IF or loop statements.
644 -- Another related use of this field is to record information about the
645 -- value obtained from an IF or WHILE statement condition. If the IF or
646 -- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ",
647 -- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a
648 -- Current_Value field, RELOP is one of the six relational operators, and
649 -- VAL is a compile-time known value then the Current_Value field of OBJ
650 -- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node
651 -- of the relevant construct, and the Condition field of this can be
652 -- consulted to give information about the value of OBJ. For more details
653 -- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition.
655 -- Debug_Info_Off (Flag166)
656 -- Present in all entities. Set if a pragma Suppress_Debug_Info applies
657 -- to the entity, or if internal processing in the compiler determines
658 -- that suppression of debug information is desirable. Note that this
659 -- flag is only for use by the front end as part of the processing for
660 -- determining if Needs_Debug_Info should be set. The back end should
661 -- always test Needs_Debug_Info, it should never test Debug_Info_Off.
663 -- Debug_Renaming_Link (Node13)
664 -- Used to link the enumeration literal of a debug renaming declaration
665 -- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
666 -- details of the use of this field.
668 -- Declaration_Node (synthesized)
669 -- Applies to all entities. Returns the tree node for the declaration
670 -- that declared the entity. Normally this is just the Parent of the
671 -- entity. One exception arises with child units, where the parent of
672 -- the entity is a selected component or a defining program unit name.
673 -- Another exception is that if the entity is an incomplete type that
674 -- has been completed, then we obtain the declaration node denoted by
675 -- the full type, i.e. the full type declaration node.
677 -- Default_Expr_Function (Node21)
678 -- Present in parameters. It holds the entity of the parameterless
679 -- function that is built to evaluate the default expression if it is
680 -- more complex than a simple identifier or literal. For the latter
681 -- simple cases or if there is no default value, this field is Empty.
683 -- Default_Expressions_Processed (Flag108)
684 -- A flag in subprograms (functions, operators, procedures) and in
685 -- entries and entry families used to indicate that default expressions
686 -- have been processed and to avoid multiple calls to process the
687 -- default expressions (see Freeze.Process_Default_Expressions), which
688 -- would not only waste time, but also generate false error messages.
690 -- Default_Value (Node20)
691 -- Present in formal parameters. Points to the node representing the
692 -- expression for the default value for the parameter. Empty if the
693 -- parameter has no default value (which is always the case for OUT
694 -- and IN OUT parameters in the absence of errors).
696 -- Delay_Cleanups (Flag114)
697 -- Present in entities that have finalization lists (subprograms
698 -- blocks, and tasks). Set if there are pending generic body
699 -- instantiations for the corresponding entity. If this flag is
700 -- set, then generation of cleanup actions for the corresponding
701 -- entity must be delayed, since the insertion of the generic body
702 -- may affect cleanup generation (see Inline for further details).
704 -- Delay_Subprogram_Descriptors (Flag50)
705 -- Present in entities for which exception subprogram descriptors
706 -- are generated (subprograms, package declarations and package
707 -- bodies). Present if there are pending generic body instantiations
708 -- for the corresponding entity. If this flag is set, then generation
709 -- of the subprogram descriptor for the corresponding enities must
710 -- be delayed, since the insertion of the generic body may add entries
711 -- to the list of handlers.
713 -- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
714 -- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
715 -- a block (in which case Delay_Subprogram_Descriptors is set for the
716 -- containing subprogram). In addition Delay_Subprogram_Descriptors is
717 -- set for a library level package declaration or body which contains
718 -- delayed instantiations (in this case the descriptor refers to the
719 -- enclosing elaboration procedure).
721 -- Delta_Value (Ureal18)
722 -- Present in fixed and decimal types. Points to a universal real
723 -- that holds value of delta for the type, as given in the declaration
724 -- or as inherited by a subtype or derived type.
726 -- Dependent_Instances (Elist8)
727 -- Present in packages that are instances. Holds list of instances
728 -- of inner generics. Used to place freeze nodes for those instances
729 -- after that of the current one, i.e. after the corresponding generic
732 -- Depends_On_Private (Flag14)
733 -- Present in all type entities. Set if the type is private or if it
734 -- depends on a private type.
736 -- Designated_Type (synthesized)
737 -- Applies to access types. Returns the designated type. Differs
738 -- from Directly_Designated_Type in that if the access type refers
739 -- to an incomplete type, and the full type is available, then this
740 -- full type is returned instead of the incomplete type.
742 -- Digits_Value (Uint17)
743 -- Present in floating point types and subtypes and decimal types and
744 -- subtypes. Contains the Digits value specified in the declaration.
746 -- Directly_Designated_Type (Node20)
747 -- Present in access types. This field points to the type that is
748 -- directly designated by the access type. In the case of an access
749 -- type to an incomplete type, this field references the incomplete
750 -- type. Note that in the semantic processing, what is useful in
751 -- nearly all cases is the full type designated by the access type.
752 -- The function Designated_Type obtains this full type in the case of
753 -- access to an incomplete type.
755 -- Discard_Names (Flag88)
756 -- Present in types and exception entities. Set if pragma Discard_Names
757 -- applies to the entity. It is also set for declarative regions and
758 -- package specs for which a Discard_Names pragma with zero arguments
759 -- has been encountered. The purpose of setting this flag is to be able
760 -- to set the Discard_Names attribute on enumeration types declared
761 -- after the pragma within the same declarative region. This flag is
762 -- set to False if a Keep_Names pragma appears for an enumeration type.
764 -- Discriminal (Node17)
765 -- Present in discriminants (Discriminant formal: GNAT's first
766 -- coinage). The entity used as a formal parameter that corresponds
767 -- to a discriminant. See section "Handling of Discriminants" for
768 -- full details of the use of discriminals.
770 -- Discriminal_Link (Node10)
771 -- Present in discriminals (which have an Ekind of E_In_Parameter,
772 -- or E_Constant), points back to corresponding discriminant.
774 -- Discriminant_Checking_Func (Node20)
775 -- Present in components. Points to the defining identifier of the
776 -- function built by the expander returns a Boolean indicating whether
777 -- the given record component exists for the current discriminant
780 -- Discriminant_Constraint (Elist21)
781 -- Present in entities whose Has_Discriminants flag is set (concurrent
782 -- types, subtypes, record types and subtypes, private types and
783 -- subtypes, limited private types and subtypes and incomplete types).
784 -- It is an error to reference the Discriminant_Constraint field if
785 -- Has_Discriminants is False.
787 -- If the Is_Constrained flag is set, Discriminant_Constraint points
788 -- to an element list containing the discriminant constraints in the
789 -- same order in which the discriminants are declared.
791 -- If the Is_Constrained flag is not set but the discriminants of the
792 -- unconstrained type have default initial values then this field
793 -- points to an element list giving these default initial values in
794 -- the same order in which the discriminants are declared. Note that
795 -- in this case the entity cannot be a tagged record type, because
796 -- discriminants in this case cannot have defaults.
798 -- If the entity is a tagged record implicit type, then this field is
799 -- inherited from the first subtype (so that the itype is subtype
800 -- conformant with its first subtype, which is needed when the first
801 -- subtype overrides primitive operations inherited by the implicit
804 -- In all other cases Discriminant_Constraint contains the empty
805 -- Elist (ie it is initialized with a call to New_Elmt_List).
807 -- Discriminant_Default_Value (Node20)
808 -- Present in discriminants. Points to the node representing the
809 -- expression for the default value of the discriminant. Set to
810 -- Empty if the discriminant has no default value.
812 -- Discriminant_Number (Uint15)
813 -- Present in discriminants. Gives the ranking of a discriminant in
814 -- the list of discriminants of the type, i.e. a sequential integer
815 -- index starting at 1 and ranging up to Number_Discriminants.
817 -- DTC_Entity (Node16)
818 -- Present in function and procedure entities. Set to Empty unless
819 -- the subprogram is dispatching in which case it references the
820 -- Dispatch Table pointer Component. That is to say the component _tag
821 -- for regular Ada tagged types, for CPP_Class types and their
822 -- descendants this field points to the component entity in the record
823 -- that is the Vtable pointer for the Vtable containing the entry that
824 -- references the subprogram.
826 -- DT_Entry_Count (Uint15)
827 -- Present in E_Component entities. Only used for component marked
828 -- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
830 -- DT_Offset_To_Top_Func (Node25)
831 -- Present in E_Component entities. Only used for component marked
832 -- Is_Tag. If present it stores the Offset_To_Top function used to
833 -- provide this value in tagged types whose ancestor has discriminants.
835 -- DT_Position (Uint15)
836 -- Present in function and procedure entities which are dispatching
837 -- (should not be referenced without first checking that flag
838 -- Is_Dispatching_Operation is True). Contains the offset into
839 -- the Vtable for the entry that references the subprogram.
842 -- Present in all entities. Contains a value of the enumeration type
843 -- Entity_Kind declared in a subsequent section in this spec.
845 -- Elaborate_Body_Desirable (Flag210)
846 -- Present in package entities. Set if the elaboration circuitry detects
847 -- a case where there is a package body that modifies one or more visible
848 -- entities in the package spec and there is no explicit Elaborate_Body
849 -- pragma for the package. This information is passed on to the binder,
850 -- which attempts, but does not promise, to elaborate the body as close
851 -- to the spec as possible.
853 -- Elaboration_Entity (Node13)
854 -- Present in generic and non-generic package and subprogram
855 -- entities. This is a boolean entity associated with the unit that
856 -- is initiallly set to False, and is set True when the unit is
857 -- elaborated. This is used for two purposes. First, it is used to
858 -- implement required access before elaboration checks (the flag
859 -- must be true to call a subprogram at elaboration time). Second,
860 -- it is used to guard against repeated execution of the generated
863 -- Note that we always allocate this flag, and set this field, but
864 -- we do not always actually use it. It is only used if it is needed
865 -- for access-before-elaboration use (see Elaboration_Entity_Required
866 -- flag) or if either the spec or the body has elaboration code. If
867 -- neither of these two conditions holds, then the entity is still
868 -- allocated (since we don't know early enough whether or not there
869 -- is elaboration code), but is simply not used for any purpose.
871 -- Elaboration_Entity_Required (Flag174)
872 -- Present in generics and non-generic package and subprogram
873 -- entities. Set only if Elaboration_Entity is non-Empty to indicate
874 -- that the boolean is required to be set even if there is no other
875 -- elaboration code. This occurs when the Elaboration_Entity flag
876 -- is used for required access-before-elaboration checking. If the
877 -- flag is only for preventing multiple execution of the elaboration
878 -- code, then if there is no other elaboration code, obviously there
879 -- is no need to set the flag.
881 -- Enclosing_Dynamic_Scope (synthesized)
882 -- Applies to all entities. Returns the closest dynamic scope in which
883 -- the entity is declared or Standard_Standard for library-level entities
885 -- Enclosing_Scope (Node18)
886 -- Present in labels. Denotes the innermost enclosing construct that
887 -- contains the label. Identical to the scope of the label, except for
888 -- labels declared in the body of an accept statement, in which case the
889 -- entry_name is the Enclosing_Scope. Used to validate goto's within
890 -- accept statements.
892 -- Entry_Accepted (Flag152)
893 -- Present in E_Entry and E_Entry_Family entities. Set if there is
894 -- at least one accept for this entry in the task body. Used to
895 -- generate warnings for missing accepts.
897 -- Entry_Bodies_Array (Node15)
898 -- Present in protected types for which Has_Entries is true.
899 -- This is the defining identifier for the array of entry body
900 -- action procedures and barrier functions used by the runtime to
901 -- execute the user code associated with each entry.
903 -- Entry_Cancel_Parameter (Node23)
904 -- Present in blocks. This only applies to a block statement for
905 -- which the Is_Asynchronous_Call_Block flag is set. It
906 -- contains the defining identifier of an object that must be
907 -- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
908 -- call in the cleanup handler added to the block by
909 -- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
910 -- object for task entry calls and a Communications_Block object
911 -- in the case of protected entry calls. In both cases the objects
912 -- are declared in outer scopes to this block.
914 -- Entry_Component (Node11)
915 -- Present in formal parameters (in, in out and out parameters). Used
916 -- only for formals of entries. References the corresponding component
917 -- of the entry parameter record for the entry.
919 -- Entry_Formal (Node16)
920 -- Present in components of the record built to correspond to entry
921 -- parameters. This field points from the component to the formal. It
922 -- is the back pointer corresponding to Entry_Component.
924 -- Entry_Index_Constant (Node18)
925 -- Present in an entry index parameter. This is an identifier that
926 -- eventually becomes the name of a constant representing the index
927 -- of the entry family member whose entry body is being executed. Used
928 -- to expand references to the entry index specification identifier.
930 -- Entry_Index_Type (synthesized)
931 -- Applies to an entry family. Denotes Etype of the subtype indication
932 -- in the entry declaration. Used to resolve the index expression in an
933 -- accept statement for a member of the family, and in the prefix of
934 -- 'COUNT when it applies to a family member.
936 -- Entry_Parameters_Type (Node15)
937 -- Present in entries. Points to the access-to-record type that is
938 -- constructed by the expander to hold a reference to the parameter
939 -- values. This reference is manipulated (as an address) by the
940 -- tasking runtime. The designated record represents a packaging
941 -- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
942 -- for further details). Entry_Parameters_Type is Empty if the entry
943 -- has no parameters.
945 -- Enumeration_Pos (Uint11)
946 -- Present in enumeration literals. Contains the position number
947 -- corresponding to the value of the enumeration literal.
949 -- Enumeration_Rep (Uint12)
950 -- Present in enumeration literals. Contains the representation that
951 -- corresponds to the value of the enumeration literal. Note that
952 -- this is normally the same as Enumeration_Pos except in the presence
953 -- of representation clauses, where Pos will still represent the
954 -- position of the literal within the type and Rep will have be the
955 -- value given in the representation clause.
957 -- Enumeration_Rep_Expr (Node22)
958 -- Present in enumeration literals. Points to the expression in an
959 -- associated enumeration rep clause that provides the representation
960 -- value for this literal. Empty if no enumeration rep clause for this
961 -- literal (or if rep clause does not have an entry for this literal,
962 -- an error situation). This is also used to catch duplicate entries
963 -- for the same literal.
965 -- Enum_Pos_To_Rep (Node23)
966 -- Present in enumeration types (but not enumeration subtypes). Set to
967 -- Empty unless the enumeration type has a non-standard representation
968 -- (i.e. at least one literal has a representation value different from
969 -- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
970 -- array constructed when the type is frozen that maps Pos values to
971 -- corresponding Rep values. The index type of this array is Natural,
972 -- and the component type is a suitable integer type that holds the
973 -- full range of representation values.
975 -- Equivalent_Type (Node18)
976 -- Present in class wide types and subtypes, access to protected
977 -- subprogram types, and in exception_types. For a classwide type, it
978 -- is always Empty. For a class wide subtype, it points to an entity
979 -- created by the expander which gives Gigi an easily understandable
980 -- equivalent of the class subtype with a known size (given by an
981 -- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
982 -- details. For E_exception_type, this points to the record containing
983 -- the data necessary to represent exceptions (for further details, see
984 -- System.Standard_Library. For access_to_protected subprograms, it
985 -- denotes a record that holds pointers to the operation and to the
986 -- protected object. For remote Access_To_Subprogram types, it denotes
987 -- the record that is the fat pointer representation of an RAST.
990 -- Present in all types and subtypes, and also for components, constants,
991 -- and variables, including exceptions where it refers to the static data
992 -- allocated for an exception. Contains the Object_Size of the type or of
993 -- the object. A value of zero indicates that the value is not yet known.
995 -- For the case of components where a component clause is present, the
996 -- value is the value from the component clause, which must be non-
997 -- negative (but may be zero, which is acceptable for the case of
998 -- a type with only one possible value). It is also possible for Esize
999 -- of a component to be set without a component clause present, which
1000 -- means that the component size is specified, but not the position.
1001 -- See also RM_Size and the section on "Handling of Type'Size Values".
1002 -- During gigi processing, the value is back annotated for all zero
1003 -- values, so that after the call to gigi, the value is properly set.
1006 -- Present in all entities. Represents the type of the entity, which
1007 -- is itself another entity. For a type entity, points to the parent
1008 -- type for a derived type, or if the type is not derived, points to
1009 -- itself. For a subtype entity, Etype points to the base type. For
1010 -- a class wide type, points to the parent type. For a subprogram or
1011 -- subprogram type, Etype has the return type of a function or is set
1012 -- to Standard_Void_Type to represent a procedure.
1014 -- Exception_Code (Uint22)
1015 -- Present in exception entitites. Set to zero unless either an
1016 -- Import_Exception or Export_Exception pragma applies to the
1017 -- pragma and specifies a Code value. See description of these
1018 -- pragmas for details. Note that this field is relevant only if
1019 -- Is_VMS_Exception is set.
1021 -- Extra_Formal (Node15)
1022 -- Present in formal parameters in the non-generic case. Certain
1023 -- parameters require extra implicit information to be passed
1024 -- (e.g. the flag indicating if an unconstrained variant record
1025 -- argument is constrained, and the accessibility level for
1026 -- access parameters. See description of Extra_Constrained,
1027 -- Extra_Accessibility fields for further details. Extra formal
1028 -- parameters are constructed to represent these values, and
1029 -- chained to the end of the list of formals using the
1030 -- Extra_Formal field (i.e. the Extra_Formal field of the last
1031 -- "real" formal points to the first extra formal, and the
1032 -- Extra_Formal field of each extra formal points to the next
1033 -- one, with Empty indicating the end of the list of extra
1036 -- Extra_Formals (Node28)
1037 -- Applies to subprograms and subprogram types, and also in entries
1038 -- and entry families. Returns first extra formal of the subprogram
1039 -- or entry. Returns Empty if there are no extra formals.
1041 -- Extra_Accessibility (Node13)
1042 -- Present in formal parameters in the non-generic case if
1043 -- expansion is active. Normally Empty, but if a parameter is
1044 -- one for which a dynamic accessibility check is required, then
1045 -- an extra formal of type Natural is created (see description
1046 -- of field Extra_Formal), and the Extra_Accessibility field of
1047 -- the formal parameter points to the entity for this extra
1048 -- formal. Also present in variables when compiling receiving
1049 -- stubs. In this case, a non Empty value means that this
1050 -- variable's accessibility depth has been transmitted by the
1051 -- caller and must be retrieved through the entity designed by
1052 -- this field instead of being computed.
1054 -- Extra_Constrained (Node23)
1055 -- Present in formal parameters in the non-generic case if
1056 -- expansion is active. Normally Empty, but if a parameter is
1057 -- one for which a dynamic indication of its constrained status
1058 -- is required, then an extra formal of type Boolean is created
1059 -- (see description of field Extra_Formal), and the
1060 -- Extra_Constrained field of the formal parameter points to the
1061 -- entity for this extra formal. Also present in variables when
1062 -- compiling receiving stubs. In this case, a non empty value
1063 -- means that this variable's constrained status has been
1064 -- transmitted by the caller and must be retrieved through the
1065 -- entity designed by this field instead of being computed.
1067 -- Finalization_Chain_Entity (Node19)
1068 -- Present in scopes that can have finalizable entities (blocks,
1069 -- functions, procedures, tasks, entries, return statements). When this
1070 -- field is empty it means that there are no finalization actions to
1071 -- perform on exit of the scope. When this field contains 'Error', it
1072 -- means that no finalization actions should happen at this level and
1073 -- the finalization chain of a parent scope shall be used (??? this is
1074 -- an improper use of 'Error' and should be changed). Otherwise it
1075 -- contains an entity of type Finalizable_Ptr that is the head of the
1076 -- list of objects to finalize on exit. See "Finalization Management"
1077 -- section in exp_ch7.adb for more details.
1079 -- Finalize_Storage_Only (Flag158) [base type only]
1080 -- Present in all types. Set on direct controlled types to which a
1081 -- valid Finalize_Storage_Only pragma applies. This flag is also set on
1082 -- composite types when they have at least one controlled component and
1083 -- all their controlled components are Finalize_Storage_Only. It is also
1084 -- inherited by type derivation except for direct controlled types where
1085 -- the Finalize_Storage_Only pragma is required at each level of
1088 -- First_Component (synthesized)
1089 -- Applies to record types. Returns the first component by following the
1090 -- chain of declared entities for the record until a component is found
1091 -- (one with an Ekind of E_Component). The discriminants are skipped. If
1092 -- the record is null, then Empty is returned.
1094 -- First_Component_Or_Discriminant (synthesized)
1095 -- Similar to First_Component, but discriminants are not skipped, so will
1096 -- find the first discriminant if discriminants are present.
1098 -- First_Discriminant (synthesized)
1099 -- Applies to types with discriminants. The discriminants are the first
1100 -- entities declared in the type, so normally this is equivalent to
1101 -- First_Entity. The exception arises for tagged types, where the tag
1102 -- itself is prepended to the front of the entity chain, so the
1103 -- First_Discriminant function steps past the tag if it is present.
1105 -- First_Entity (Node17)
1106 -- Present in all entities which act as scopes to which a list of
1107 -- associated entities is attached (blocks, class subtypes and types,
1108 -- entries, functions, loops, packages, procedures, protected objects,
1109 -- record types and subtypes, private types, task types and subtypes).
1110 -- Points to a list of associated entities using the Next_Entity field
1111 -- as a chain pointer with Empty marking the end of the list.
1113 -- First_Formal (synthesized)
1114 -- Applies to subprograms and subprogram types, and also in entries
1115 -- and entry families. Returns first formal of the subprogram or entry.
1116 -- The formals are the first entities declared in a subprogram or in
1117 -- a subprogram type (the designated type of an Access_To_Subprogram
1118 -- definition) or in an entry.
1120 -- First_Formal_With_Extras (synthesized)
1121 -- Applies to subprograms and subprogram types, and also in entries
1122 -- and entry families. Returns first formal of the subprogram or entry.
1123 -- Returns Empty if there are no formals. The list returned includes
1124 -- all the extra formals (see description of Extra_Formals field).
1126 -- First_Index (Node17)
1127 -- Present in array types and subtypes and in string types and subtypes.
1128 -- By introducing implicit subtypes for the index constraints, we have
1129 -- the same structure for constrained and unconstrained arrays, subtype
1130 -- marks and discrete ranges are both represented by a subtype. This
1131 -- function returns the tree node corresponding to an occurrence of the
1132 -- first index (NOT the entity for the type). Subsequent indexes are
1133 -- obtained using Next_Index. Note that this field is present for the
1134 -- case of string literal subtypes, but is always Empty.
1136 -- First_Literal (Node17)
1137 -- Present in all enumeration types, including character and boolean
1138 -- types. This field points to the first enumeration literal entity
1139 -- for the type (i.e. it is set to First (Literals (N)) where N is
1140 -- the enumeration type definition node. A special case occurs with
1141 -- standard character and wide character types, where this field is
1142 -- Empty, since there are no enumeration literal lists in these cases.
1143 -- Note that this field is set in enumeration subtypes, but it still
1144 -- points to the first literal of the base type in this case.
1146 -- First_Optional_Parameter (Node14)
1147 -- Present in (non-generic) function and procedure entities. Set to a
1148 -- non-null value only if a pragma Import_Function, Import_Procedure
1149 -- or Import_Valued_Procedure specifies a First_Optional_Parameter
1150 -- argument, in which case this field points to the parameter entity
1151 -- corresponding to the specified parameter.
1153 -- First_Private_Entity (Node16)
1154 -- Present in all entities containing private parts (packages,
1155 -- protected types and subtypes, task types and subtypes). The
1156 -- entities on the entity chain are in order of declaration, so the
1157 -- entries for private entities are at the end of the chain. This
1158 -- field points to the first entity for the private part. It is
1159 -- Empty if there are no entities declared in the private part or
1160 -- if there is no private part.
1162 -- First_Rep_Item (Node6)
1163 -- Present in all entities. If non-empty, points to a linked list of
1164 -- representation pragmas nodes and representation clause nodes that
1165 -- apply to the entity, linked using Next_Rep_Item, with Empty marking
1166 -- the end of the list. In the case of derived types and subtypes, the
1167 -- new entity inherits the chain at the point of declaration. This
1168 -- means that it is possible to have multiple instances of the same
1169 -- kind of rep item on the chain, in which case it is the first one
1170 -- that applies to the entity.
1172 -- For most representation items, the representation information is
1173 -- reflected in other fields and flags in the entity. For example if
1174 -- a record representation clause is present, the component entities
1175 -- reflect the specified information. However, there are some items
1176 -- that are only reflected in the chain. These include:
1178 -- Alignment attribute definition clause
1179 -- Machine_Attribute pragma
1180 -- Link_Alias pragma
1181 -- Link-Section pragma
1182 -- Weak_External pragma
1184 -- If any of these items are present, then the flag Has_Gigi_Rep_Item
1185 -- is set, indicating that Gigi should search the chain.
1187 -- Other representation items are included in the chain so that error
1188 -- messages can easily locate the relevant nodes for posting errors.
1189 -- Note in particular that size clauses are present only for this
1190 -- purpose, and should only be accessed if Has_Size_Clause is set.
1192 -- First_Stored_Discriminant (synthesized)
1193 -- Applies to types with discriminants. Gives the first discriminant
1194 -- stored in the object. In many cases, these are the same as the
1195 -- normal visible discriminants for the type, but in the case of
1196 -- renamed discriminants, this is not always the case.
1198 -- For tagged types, and untagged types which are root types or
1199 -- derived types but which do not rename discriminants in their
1200 -- root type, the stored discriminants are the same as the actual
1201 -- discriminants of the type, and hence this function is the same
1202 -- as First_Discriminant.
1204 -- For derived non-tagged types that rename discriminants in the root
1205 -- type this is the first of the discriminants that occur in the
1206 -- root type. To be precise, in this case stored discriminants are
1207 -- entities attached to the entity chain of the derived type which
1208 -- are a copy of the discriminants of the root type. Furthermore their
1209 -- Is_Completely_Hidden flag is set since although they are actually
1210 -- stored in the object, they are not in the set of discriminants that
1211 -- is visble in the type.
1213 -- For derived untagged types, stored discriminants are the real
1214 -- discriminants from Gigi's standpoint, i.e. those that will be
1215 -- stored in actual objects of the type.
1217 -- First_Subtype (synthesized)
1218 -- Applies to all types and subtypes. For types, yields the first
1219 -- subtype of the type. For subtypes, yields the first subtype of
1220 -- the base type of the subtype.
1222 -- First_Tag_Component (synthesized)
1223 -- Applies to tagged record types, returns the entity for the first
1224 -- _Tag field in this record.
1226 -- Freeze_Node (Node7)
1227 -- Present in all entities. If there is an associated freeze node for
1228 -- the entity, this field references this freeze node. If no freeze
1229 -- node is associated with the entity, then this field is Empty. See
1230 -- package Freeze for further details.
1232 -- From_With_Type (Flag159)
1233 -- Present in package and type entities. Indicates that the entity
1234 -- appears in a With_Type clause in the context of some other unit,
1235 -- either as the prefix (which must be a package), or as a type name.
1236 -- The package can only be used to retrieve such a type, and the type
1237 -- can be used only in component declarations and access definitions.
1238 -- The With_Type clause is used to construct mutually recursive
1239 -- types, i.e. record types (Java classes) that hold pointers to each
1240 -- other. If such a type is an access type, it has no explicit freeze
1241 -- node, so that the back-end does not attempt to elaborate it.
1242 -- Currently this flag is also used to implement Ada 2005 (AI-50217).
1243 -- It will be renamed to From_Limited_With after removal of the current
1244 -- GNAT with_type clause???
1246 -- Full_View (Node11)
1247 -- Present in all type and subtype entities and in deferred constants.
1248 -- References the entity for the corresponding full type declaration.
1249 -- For all types other than private and incomplete types, this field
1250 -- always contains Empty. See also Underlying_Type.
1252 -- Function_Returns_With_DSP (Flag169)
1253 -- Present in all subprogram entities, and type entities for access
1254 -- to subprogram values. Set True if the function (or referenced
1255 -- function in the case of an access value) returns with using the
1256 -- DSP (depressed stack pointer) approach. This can only be set
1257 -- True if Targparm.Functions_Return_By_DSP_On_Target is True and
1258 -- the function returns a value of a type whose size is not known
1261 -- Note: this flag is obsolete, it is always False ???
1263 -- Generic_Homonym (Node11)
1264 -- Present in generic packages. The generic homonym is the entity of
1265 -- a renaming declaration inserted in every generic unit. It is used
1266 -- to resolve the name of a local entity that is given by a qualified
1267 -- name, when the generic entity itself is hidden by a local name.
1269 -- Generic_Renamings (Elist23)
1270 -- Present in package and subprogram instances. Holds mapping that
1271 -- associates generic parameters with the corresponding instances, in
1272 -- those cases where the instance is an entity.
1274 -- Handler_Records (List10)
1275 -- Present in subprogram and package entities. Points to a list of
1276 -- identifiers referencing the handler record entities for the
1277 -- corresponding unit.
1279 -- Has_Aliased_Components (Flag135) [implementation base type only]
1280 -- Present in array type entities. Indicates that the component type
1281 -- of the array is aliased.
1283 -- Has_Alignment_Clause (Flag46)
1284 -- Present in all type entities and objects. Indicates if an alignment
1285 -- clause has been given for the entity. If set, then Alignment_Clause
1286 -- returns the N_Attribute_Definition node for the alignment attribute
1287 -- definition clause. Note that it is possible for this flag to be False
1288 -- even when Alignment_Clause returns non_Empty (this happens in the case
1289 -- of derived type declarations).
1291 -- Has_All_Calls_Remote (Flag79)
1292 -- Present in all library unit entities. Set true if the library unit
1293 -- has an All_Calls_Remote pragma. Note that such entities must also
1294 -- be RCI entities, so the flag Is_Remote_Call_Interface will always
1295 -- be set if this flag is set.
1297 -- Has_Anon_Block_Suffix (Flag201)
1298 -- Present in all entities. Set if the entity is nested within one or
1299 -- more anonymous blocks and the Chars field contains a name with an
1300 -- anonymous block suffix (see Exp_Dbug for furthert details).
1302 -- Has_Atomic_Components (Flag86) [implementation base type only]
1303 -- Present in all types and objects. Set only for an array type or
1304 -- an array object if a valid pragma Atomic_Components applies to the
1305 -- type or object. Note that in the case of an object, this flag is
1306 -- only set on the object if there was an explicit pragma for the
1307 -- object. In other words, the proper test for whether an object has
1308 -- atomic components is to see if either the object or its base type
1309 -- has this flag set. Note that in the case of a type, the pragma will
1310 -- be chained to the rep item chain of the first subtype in the usual
1313 -- Has_Attach_Handler (synthesized)
1314 -- Applies to record types that are constructed by the expander to
1315 -- represent protected types. Returns True if there is at least one
1316 -- Attach_Handler pragma in the corresponding specification.
1318 -- Has_Biased_Representation (Flag139)
1319 -- Present in discrete types (where it applies to the type'size value),
1320 -- and to objects (both stand-alone and components), where it applies to
1321 -- the size of the object from a size or record component clause. In
1322 -- all cases it indicates that the size in question is smaller than
1323 -- would normally be required, but that the size requirement can be
1324 -- satisfied by using a biased representation, in which stored values
1325 -- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
1326 -- reduce the required size. For example, a type with a range of 1..2
1327 -- takes one bit, using 0 to represent 1 and 1 to represent 2.
1329 -- Note that in the object and component cases, the flag is only set
1330 -- if the type is unbiased, but the object specifies a smaller size
1331 -- than the size of the type, forcing biased representation for the
1332 -- object, but the subtype is still an unbiased type.
1334 -- Has_Completion (Flag26)
1335 -- Present in all entities that require a completion (functions,
1336 -- procedures, private types, limited private types, incomplete types,
1337 -- constants and packages that require a body). The flag is set if the
1338 -- completion has been encountered and analyzed.
1340 -- Has_Completion_In_Body (Flag71)
1341 -- Present in all entities for types and subtypes. Set only in "Taft
1342 -- amendment types" (incomplete types whose full declaration appears in
1343 -- the package body).
1345 -- Has_Complex_Representation (Flag140) [implementation base type only]
1346 -- Present in all type entities. Set only for a record base type to
1347 -- which a valid pragma Complex_Representation applies.
1349 -- Has_Component_Size_Clause (Flag68) [implementation base type only]
1350 -- Present in all type entities. Set if a component size clause is
1351 -- present for the given type. Note that this flag can be False even
1352 -- if Component_Size is non-zero (happens in the case of derived types).
1354 -- Has_Constrained_Partial_View (Flag187)
1355 -- Present in private type and their completions, when the private
1356 -- type has no discriminants and the full view has discriminants with
1357 -- defaults. In Ada 2005 heap-allocated objects of such types are not
1358 -- constrained, and can change their discriminants with full assignment.
1360 -- Has_Contiguous_Rep (Flag181)
1361 -- Present in enumeration types. True if the type as a representation
1362 -- clause whose entries are successive integers.
1364 -- Has_Controlling_Result (Flag98)
1365 -- Present in E_Function entities. True if the function is a primitive
1366 -- function of a tagged type which can dispatch on result.
1368 -- Has_Controlled_Component (Flag43) [base type only]
1369 -- Present in all entities. Set only for composite type entities which
1370 -- contain a component that either is a controlled type, or itself
1371 -- contains controlled component (i.e. either Has_Controlled_Component
1372 -- or Is_Controlled is set for at least one component).
1374 -- Has_Convention_Pragma (Flag119)
1375 -- Present in an entity for which a Convention, Import, or Export
1376 -- pragma has been given. Used to prevent more than one such pragma
1377 -- appearing for a given entity (RM B.1(45)).
1379 -- Has_Delayed_Freeze (Flag18)
1380 -- Present in all entities. Set to indicate that an explicit freeze
1381 -- node must be generated for the entity at its freezing point. See
1382 -- separate section ("Delayed Freezing and Elaboration") for details.
1384 -- Has_Discriminants (Flag5)
1385 -- Present in all types and subtypes. For types that are allowed to have
1386 -- discriminants (record types and subtypes, task types and subtypes,
1387 -- protected types and subtypes, private types, limited private types,
1388 -- and incomplete types), indicates if the corresponding type or subtype
1389 -- has a known discriminant part. Always false for all other types.
1391 -- Has_Entries (synthesized)
1392 -- Applies to concurrent types. True if any entries are declared
1393 -- within the task or protected definition for the type.
1395 -- Has_Enumeration_Rep_Clause (Flag66)
1396 -- Present in enumeration types. Set if an enumeration representation
1397 -- clause has been given for this enumeration type. Used to prevent more
1398 -- than one enumeration representation clause for a given type. Note
1399 -- that this does not imply a representation with holes, since the rep
1400 -- clause may merely confirm the default 0..N representation.
1402 -- Has_External_Tag_Rep_Clause (Flag110)
1403 -- Present in tagged types. Set if an external_tag rep. clause has been
1404 -- given for this type. Use to avoid the generation of the default
1407 -- Has_Exit (Flag47)
1408 -- Present in loop entities. Set if the loop contains an exit statement.
1410 -- Has_Foreign_Convention (synthesized)
1411 -- Applies to all entities. Determines if the Convention for the
1412 -- entity is a foreign convention (i.e. is other than Convention_Ada,
1413 -- Convention_Intrinsic, Convention_Entry or Convention_Protected).
1415 -- Has_Forward_Instantiation (Flag175)
1416 -- Present in package entities. Set true for packages that contain
1417 -- instantiations of local generic entities, before the corresponding
1418 -- generic body has been seen. If a package has a forward instantiation,
1419 -- we cannot inline subprograms appearing in the same package because
1420 -- the placement requirements of the instance will conflict with the
1421 -- linear elaboration of front-end inlining.
1423 -- Has_Fully_Qualified_Name (Flag173)
1424 -- Present in all entities. Set True if the name in the Chars field
1425 -- has been replaced by the fully qualified name, as used for debug
1426 -- output. See Exp_Dbug for a full description of the use of this
1427 -- flag and also the related flag Has_Qualified_Name.
1429 -- Has_Gigi_Rep_Item (Flag82)
1430 -- This flag is set if the rep item chain (referenced by First_Rep_Item
1431 -- and linked through the Next_Rep_Item chain) contains a representation
1432 -- item that needs to be specially processed by Gigi, i.e. one of the
1435 -- Machine_Attribute pragma
1436 -- Linker_Alias pragma
1437 -- Linker_Section pragma
1438 -- Linker_Constructor pragma
1439 -- Linker_Destructor pragma
1440 -- Weak_External pragma
1442 -- If this flag is set, then Gigi should scan the rep item chain to
1443 -- process any of these items that appear. At least one such item will
1446 -- Has_Homonym (Flag56)
1447 -- Present in all entities. Set if an entity has a homonym in the same
1448 -- scope. Used by Gigi to generate unique names for such entities.
1450 -- Has_Interrupt_Handler (synthesized)
1451 -- Applies to all protected type entities. Set if the protected type
1452 -- definition contains at least one procedure to which a pragma
1453 -- Interrupt_Handler applies.
1455 -- Has_Machine_Radix_Clause (Flag83)
1456 -- Present in decimal types and subtypes, set if a Machine_Radix
1457 -- representation clause is present. This flag is used to detect
1458 -- the error of multiple machine radix clauses for a single type.
1460 -- Has_Master_Entity (Flag21)
1461 -- Present in entities that can appear in the scope stack (see spec
1462 -- of Sem). It is set if a task master entity (_master) has been
1463 -- declared and initialized in the corresponding scope.
1465 -- Has_Missing_Return (Flag142)
1466 -- Present in functions and generic functions. Set if there is one or
1467 -- more missing return statements in the function. This is used to
1468 -- control wrapping of the body in Exp_Ch6 to ensure that the program
1469 -- error exeption is correctly raised in this case at runtime.
1471 -- Has_Up_Level_Access (Flag215)
1472 -- Present in E_Variable and E_Constant entities. Set if the entity is
1473 -- declared in a local procedure p and is accessed in a procedure nested
1474 -- inside p. Only set when VM_Target /= No_VM currently.
1476 -- Has_Nested_Block_With_Handler (Flag101)
1477 -- Present in scope entities. Set if there is a nested block within the
1478 -- scope that has an exception handler and the two scopes are in the
1479 -- same procedure. This is used by the backend for controlling certain
1480 -- optimizations to ensure that they are consistent with exceptions.
1481 -- See documentation in Gigi for further details.
1483 -- Has_Non_Standard_Rep (Flag75) [implementation base type only]
1484 -- Present in all type entities. Set when some representation clause
1485 -- or pragma causes the representation of the item to be significantly
1486 -- modified. In this category are changes of small or radix for a
1487 -- fixed-point type, change of component size for an array, and record
1488 -- or enumeration representation clauses, as well as packed pragmas.
1489 -- All other representation clauses (e.g. Size and Alignment clauses)
1490 -- are not considered to be significant since they do not affect
1491 -- stored bit patterns.
1493 -- Has_Object_Size_Clause (Flag172)
1494 -- Present in entities for types and subtypes. Set if an Object_Size
1495 -- clause has been processed for the type Used to prevent multiple
1496 -- Object_Size clauses for a given entity.
1498 -- Has_Per_Object_Constraint (Flag154)
1499 -- Present in E_Component entities, true if the subtype of the
1500 -- component has a per object constraint. Per object constraints result
1501 -- from the following situations:
1503 -- 1. N_Attribute_Reference - when the prefix is the enclosing type and
1504 -- the attribute is Access.
1505 -- 2. N_Discriminant_Association - when the expression uses the
1506 -- discriminant of the enclosing type.
1507 -- 3. N_Index_Or_Discriminant_Constraint - when at least one of the
1508 -- individual constraints is a per object constraint.
1509 -- 4. N_Range - when the lower or upper bound uses the discriminant of
1510 -- the enclosing type.
1511 -- 5. N_Range_Constraint - when the range expression uses the
1512 -- discriminant of the enclosing type.
1514 -- Has_Persistent_BSS (Flag188)
1515 -- Present in all entities. Set True for entities to which a valid
1516 -- pragma Persistent_BSS applies. Note that although the pragma is
1517 -- only meaningful for objects, we set it for all entities in a unit
1518 -- to which the pragma applies, as well as the unit entity itself, for
1519 -- convenience in propagating the flag to contained entities.
1521 -- Has_Pragma_Controlled (Flag27) [implementation base type only]
1522 -- Present in access type entities. It is set if a pragma Controlled
1523 -- applies to the access type.
1525 -- Has_Pragma_Elaborate_Body (Flag150)
1526 -- Present in all entities. Set in compilation unit entities if a
1527 -- pragma Elaborate_Body applies to the compilation unit.
1529 -- Has_Pragma_Inline (Flag157)
1530 -- Present in all entities. Set for functions and procedures for which
1531 -- a pragma Inline or Inline_Always applies to the subprogram. Note
1532 -- that this flag can be set even if Is_Inlined is not set. This
1533 -- happens for pragma Inline (if Inline_Active is False). In other
1534 -- words, the flag Has_Pragma_Inline represents the formal semantic
1535 -- status, and is used for checking semantic correctness.
1536 -- The flag Is_Inlined indicates whether inlining is actually active
1539 -- Has_Pragma_Pack (Flag121) [implementation base type only]
1540 -- Present in all entities. If set, indicates that a valid pragma Pack
1541 -- was was given for the type. Note that this flag is not inherited by
1542 -- derived type. See also the Is_Packed flag.
1544 -- Has_Pragma_Pure (Flag203)
1545 -- Present in all entities. If set, indicates that a valid pragma Pure
1546 -- was given for the entity. In some cases, we need to test whether
1547 -- Is_Pure was explicitly set using this pragma.
1549 -- Has_Pragma_Pure_Function (Flag179)
1550 -- Present in all entities. If set, indicates that a valid pragma
1551 -- Pure_Function was given for the entity. In some cases, we need to
1552 -- know that Is_Pure was explicitly set using this pragma.
1554 -- Has_Pragma_Unreferenced (Flag180)
1555 -- Present in all entities. Set if a valid pragma Unreferenced applies
1556 -- to the pragma, indicating that no warning should be given if the
1557 -- entity has no references, but a warning should be given if it is
1558 -- in fact referenced. For private types, this flag is set in both the
1559 -- private entity and full entity if the pragma applies to either.
1561 -- Has_Pragma_Unreferenced_Objects (Flag212)
1562 -- Present in type and subtype entities. Set if a valid pragma
1563 -- Unreferenced_Objects applies to the type, indicating that no warning
1564 -- should be given for objects of such a type for being unreferenced
1565 -- (but unlike the case with pragma Unreferenced, it is ok to reference
1566 -- such an object and no warning is generated.
1568 -- Known_To_Have_Preelab_Init (Flag207)
1569 -- Present in all type and subtype entities. If set, then the type is
1570 -- known to have preelaborable initialization. In the case of a partial
1571 -- view of a private type, it is only possible for this to be set if a
1572 -- pragma Preelaborable_Initialization is given for the type. For other
1573 -- types, it is never set if the type does not have preelaborable
1574 -- initialization, it may or may not be set if the type does have
1575 -- preelaborable initialization.
1577 -- Has_Primitive_Operations (Flag120) [base type only]
1578 -- Present in all type entities. Set if at least one primitive operation
1579 -- is defined for the type.
1581 -- Has_Private_Ancestor (synthesized)
1582 -- Applies to all type and subtype entities. Returns True if at least
1583 -- one ancestor is private, and otherwise False if there are no private
1586 -- Has_Private_Declaration (Flag155)
1587 -- Present in all entities. Returns True if it is the defining entity
1588 -- of a private type declaration or its corresponding full declaration.
1589 -- This flag is thus preserved when the full and the partial views are
1590 -- exchanged, to indicate if a full type declaration is a completion.
1591 -- Used for semantic checks in E.4 (18), and elsewhere.
1593 -- Has_Qualified_Name (Flag161)
1594 -- Present in all entities. Set True if the name in the Chars field
1595 -- has been replaced by its qualified name, as used for debug output.
1596 -- See Exp_Dbug for a full description of qualification requirements.
1597 -- For some entities, the name is the fully qualified name, but there
1598 -- are exceptions. In particular, for local variables in procedures,
1599 -- we do not include the procedure itself or higher scopes. See also
1600 -- the flag Has_Fully_Qualified_Name, which is set if the name does
1601 -- indeed include the fully qualified name.
1603 -- Has_RACW (Flag214)
1604 -- Present in package spec entities. Set if the spec contains the
1605 -- declaration of a remote access-to-classwide type.
1607 -- Has_Record_Rep_Clause (Flag65) [implementation base type only]
1608 -- Present in record types. Set if a record representation clause has
1609 -- been given for this record type. Used to prevent more than one such
1610 -- clause for a given record type. Note that this is initially cleared
1611 -- for a derived type, even though the representation is inherited. See
1612 -- also the flag Has_Specified_Layout.
1614 -- Has_Recursive_Call (Flag143)
1615 -- Present in procedures. Set if a direct parameterless recursive call
1616 -- is detected while analyzing the body. Used to activate some error
1617 -- checks for infinite recursion.
1619 -- Has_Size_Clause (Flag29)
1620 -- Present in entities for types and objects. Set if a size clause is
1621 -- present for the entity. Used to prevent multiple Size clauses for a
1622 -- given entity. Note that it is always initially cleared for a derived
1623 -- type, even though the Size for such a type is inherited from a Size
1624 -- clause given for the parent type.
1626 -- Has_Small_Clause (Flag67)
1627 -- Present in ordinary fixed point types (but not subtypes). Indicates
1628 -- that a small clause has been given for the entity. Used to prevent
1629 -- multiple Small clauses for a given entity. Note that it is always
1630 -- initially cleared for a derived type, even though the Small for such
1631 -- a type is inherited from a Small clause given for the parent type.
1633 -- Has_Specified_Layout (Flag100) [implementation base type only]
1634 -- Present in all type entities. Set for a record type or subtype if
1635 -- the record layout has been specified by a record representation
1636 -- clause. Note that this differs from the flag Has_Record_Rep_Clause
1637 -- in that it is inherited by a derived type. Has_Record_Rep_Clause is
1638 -- used to indicate that the type is mentioned explicitly in a record
1639 -- representation clause, and thus is not inherited by a derived type.
1640 -- This flag is always False for non-record types.
1642 -- Has_Specified_Stream_Input (Flag190)
1643 -- Has_Specified_Stream_Output (Flag191)
1644 -- Has_Specified_Stream_Read (Flag192)
1645 -- Has_Specified_Stream_Write (Flag193)
1646 -- Present in all type and subtype entities. Set for a given view if the
1647 -- corresponding stream-oriented attribute has been defined by an
1648 -- attribute definition clause. When such a clause occurs, a TSS is set
1649 -- on the underlying full view; the flags are used to track visibility of
1650 -- the attribute definition clause for partial or incomplete views.
1652 -- Has_Static_Discriminants (Flag211)
1653 -- Present in record subtypes constrained by discriminant values. Set if
1654 -- all the discriminant values have static values, meaning that in the
1655 -- case of a variant record, the component list can be trimmed down to
1656 -- include only the components corresponding to these discriminants.
1658 -- Has_Storage_Size_Clause (Flag23) [implementation base type only]
1659 -- Present in task types and access types. It is set if a Storage_Size
1660 -- clause is present for the type. Used to prevent multiple clauses for
1661 -- one type. Note that this flag is initially cleared for a derived type
1662 -- even though the Storage_Size for such a type is inherited from a
1663 -- Storage_Size clause given for the parent type. Note that in the case
1664 -- of access types, this flag is present only in the root type, since a
1665 -- storage size clause cannot be given to a derived type.
1667 -- Has_Stream_Size_Clause (Flag184)
1668 -- This flag is present in all entities. It is set for types which have a
1669 -- Stream_Size clause attribute. Used to prevent multiple Stream_Size
1670 -- clauses for a given entity, and also whether it is necessary to check
1671 -- for a stream size clause.
1673 -- Has_Subprogram_Descriptor (Flag93)
1674 -- This flag is set on entities for which zero-cost exception subprogram
1675 -- descriptors can be generated (subprograms and library level package
1676 -- declarations and bodies). It indicates that a subprogram descriptor
1677 -- has been generated, and is used to suppress generation of multiple
1678 -- descriptors (e.g. when instantiating generic bodies).
1680 -- Has_Task (Flag30) [base type only]
1681 -- Present in all type entities. Set on task types themselves, and also
1682 -- (recursively) on any composite type which has a component for which
1683 -- Has_Task is set. The meaning is that an allocator or declaration of
1684 -- such an object must create the required tasks. Note: the flag is not
1685 -- set on access types, even if they designate an object that Has_Task.
1687 -- Has_Unchecked_Union (Flag123) [base type only]
1688 -- Present in all type entities. Set on unchecked unions themselves
1689 -- and (recursively) on any composite type which has a component for
1690 -- which Has_Unchecked_Union is set. The meaning is that a comparison
1691 -- operation for the type is not permitted. Note that the flag is not
1692 -- set on access types, even if they designate an object that has
1693 -- the flag Has_Unchecked_Union set.
1695 -- Has_Unknown_Discriminants (Flag72)
1696 -- Present in all type entities. Types can have unknown discriminants
1697 -- either from their declaration or through type derivation. The use
1698 -- of this flag exactly meets the spec in RM 3.7(26). Note that all
1699 -- class-wide types are considered to have unknown discriminants.
1700 -- Note that both Has_Discriminants and Has_Unknown_Discriminants may
1701 -- be true for a type. Class-wide types and their subtypes have
1702 -- unknown discriminants and can have declared ones as well. Private
1703 -- types declared with unknown discriminants may have a full view that
1704 -- has explicit discriminants, and both flag will be set on the partial
1705 -- view, to insure that discriminants are properly inherited in certain
1708 -- Has_Volatile_Components (Flag87) [implementation base type only]
1709 -- Present in all types and objects. Set only for an array type or
1710 -- array object if a valid pragma Volatile_Components or a valid
1711 -- pragma Atomic_Components applies to the type or object. Note that
1712 -- in the case of an object, this flag is only set on the object if
1713 -- there was an explicit pragma for the object. In other words, the
1714 -- proper test for whether an object has volatile components is to
1715 -- see if either the object or its base type has this flag set. Note
1716 -- that in the case of a type the pragma will be chained to the rep
1717 -- item chain of the first subtype in the usual manner.
1719 -- Has_Xref_Entry (Flag182)
1720 -- This flag is set if an entity has an entry in the Xref information
1721 -- generated in ali files. This is true for all source entities in the
1722 -- extended main source file. It is also true of entities in other
1723 -- packages that are referenced directly or indirectly from the main
1724 -- source file (indirect reference occurs when the main source file
1725 -- references an entity with a type reference. See package Lib.Xref
1726 -- for further details).
1728 -- Hiding_Loop_Variable (Node8)
1729 -- Present in variables. Set only if a variable of a discrete type is
1730 -- hidden by a loop variable in the same local scope, in which case
1731 -- the Hiding_Loop_Variable field of the hidden variable points to
1732 -- the E_Loop_Parameter entity doing the hiding. Used in processing
1733 -- warning messages if the hidden variable turns out to be unused
1734 -- or is referenced without being set.
1737 -- Present in all entities. Link for list of entities that have the
1738 -- same source name and that are declared in the same or enclosing
1739 -- scopes. Homonyms in the same scope are overloaded. Used for name
1740 -- resolution and for the generation of debugging information.
1742 -- Implementation_Base_Type (synthesized)
1743 -- Applies to all types. Similar to Base_Type, but never returns a
1744 -- private type when applied to a non-private type. Instead in this case,
1745 -- it always returns the Underlying_Type of the base type, so that we
1746 -- still have a concrete type. Note: it is allowed to apply
1747 -- Implementation_Base_Type to other than a type, in which case it simply
1748 -- returns the entity unchanged.
1750 -- In_Package_Body (Flag48)
1751 -- Set on the entity that denotes the package (the defining occurrence
1752 -- of the package declaration) while analyzing and expanding the package
1753 -- body. Reset on completion of analysis/expansion.
1755 -- In_Private_Part (Flag45)
1756 -- Present in all entities. Can be set only in package entities and
1757 -- objects. For package entities, this flag is set to indicate that the
1758 -- private part of the package is being analyzed. The flag is reset at
1759 -- the end of the package declaration. For objects it indicates that the
1760 -- declaration of the object occurs in the private part of a package.
1762 -- Inner_Instances (Elist23)
1763 -- Present in generic units. Contains element list of units that are
1764 -- instantiated within the given generic. Used to diagnose circular
1767 -- Interface_Name (Node21)
1768 -- Present in exceptions, functions, procedures, variables, constants,
1769 -- and packages. Set to Empty unless an export, import, or interface
1770 -- name pragma has explicitly specified an external name, in which
1771 -- case it references an N_String_Literal node for the specified
1772 -- external name. In the case of exceptions, the field is set by
1773 -- Import_Exception/Export_Exception (which can be used in OpenVMS
1774 -- versions only). Note that if this field is Empty, and Is_Imported
1775 -- or Is_Exported is set, then the default interface name is the name
1776 -- of the entity, cased in a manner that is appropriate to the system
1777 -- in use. Note that Interface_Name is ignored if an address clause
1778 -- is present (since it is meaningless in this case).
1780 -- An additional special case usage of this field is in JGNAT for
1781 -- E_Component and E_Discriminant. JGNAT allows these entities to
1782 -- be imported by specifying pragma Import within a component's
1783 -- containing record definition. This supports interfacing to
1784 -- object fields defined within Java classes, and such pragmas
1785 -- are generated by the jvm2ada binding generator tool whenever
1786 -- it processes classes with public object fields. A pragma Import
1787 -- for a component can define the External_Name of the imported
1788 -- Java field (which is generally needed, because Java names are
1792 -- Present in packages and types. Set when analyzing a use clause for
1793 -- the corresponding entity. Reset at end of corresponding declarative
1794 -- part. The flag on a type is also used to determine the visibility of
1795 -- the primitive operators of the type.
1797 -- Is_Abstract_Subprogram (Flag19)
1798 -- Present in all subprograms and entries. Set for abstract subprograms.
1799 -- Always False for enumeration literals and entries. See also
1800 -- Requires_Overriding.
1802 -- Is_Abstract_Type (Flag146)
1803 -- Present in all types. Set for abstract types.
1805 -- Is_Local_Anonymous_Access (Flag194)
1806 -- Present in access types. Set for an anonymous access type to indicate
1807 -- that the type is created for a record component with an access
1808 -- definition, an array component, or a stand-alone object. Such
1809 -- anonymous types have an accessibility level equal to that of the
1810 -- declaration in which they appear, unlike the anonymous access types
1811 -- that are created for access parameters and access discriminants.
1813 -- Is_Access_Constant (Flag69)
1814 -- Present in access types and subtypes. Indicates that the keyword
1815 -- constant was present in the access type definition.
1817 -- Is_Access_Protected_Subprogram_Type (synthesized)
1818 -- Applies to all types, true for named and anonymous access to
1819 -- protected subprograms.
1821 -- Is_Access_Type (synthesized)
1822 -- Applies to all entities, true for access types and subtypes
1824 -- Is_Ada_2005_Only (Flag185)
1825 -- Applies to all entities, true if a valid pragma Ada_05 applies to the
1826 -- entity which specifically names the entity, indicating that the entity
1827 -- is Ada 2005 only. Note that this flag is not set if the entity is part
1828 -- of a unit compiled with the normal no-argument form of pragma Ada_05.
1830 -- Is_Aliased (Flag15)
1831 -- Present in objects whose declarations carry the keyword aliased,
1832 -- and on record components that have the keyword.
1834 -- Is_Always_Inlined (synthesized)
1835 -- Present in subprograms. True if there is a pragma Inline_Always for
1838 -- Is_AST_Entry (Flag132)
1839 -- Present in entry entities. Set if a valid pragma AST_Entry applies
1840 -- to the entry. This flag can only be set in OpenVMS versions of GNAT.
1841 -- Note: we also allow the flag to appear in entry families, but given
1842 -- the current implementation of the pragma AST_Entry, this flag will
1843 -- always be False in entry families.
1845 -- Is_Atomic (Flag85)
1846 -- Present in all type entities, and also in constants, components and
1847 -- variables. Set if a pragma Atomic or Shared applies to the entity.
1848 -- In the case of private and incomplete types, this flag is set in
1849 -- both the partial view and the full view.
1851 -- Is_Array_Type (synthesized)
1852 -- Applies to all entities, true for array types and subtypes
1854 -- Is_Asynchronous (Flag81)
1855 -- Present in all type entities and in procedure entities. Set
1856 -- if a pragma Asynchronous applies to the entity.
1858 -- Is_Bit_Packed_Array (Flag122) [implementation base type only]
1859 -- Present in all entities. This flag is set for a packed array
1860 -- type that is bit packed (i.e. the component size is known by the
1861 -- front end and is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed
1862 -- is always set if Is_Bit_Packed_Array is set, but it is possible for
1863 -- Is_Packed to be set without Is_Bit_Packed_Array for the case of an
1864 -- array having one or more index types that are enumeration types
1865 -- with non-standard enumeration representations.
1867 -- Is_Boolean_Type (synthesized)
1868 -- Applies to all entities, true for boolean types and subtypes,
1869 -- i.e. Standard.Boolean and all types ultimately derived from it.
1871 -- Is_By_Copy_Type (synthesized)
1872 -- Applies to all type entities. Returns true if the entity is
1873 -- a by copy type (RM 6.2(3)).
1875 -- Is_By_Reference_Type (synthesized)
1876 -- Applies to all type entities. True if the type is required to
1877 -- be passed by reference, as defined in (RM 6.2(4-9)).
1879 -- Is_Called (Flag102)
1880 -- Present in subprograms. Returns true if the subprogram is called
1881 -- in the unit being compiled or in a unit in the context. Used for
1884 -- Is_Character_Type (Flag63)
1885 -- Present in all entities, true for character types and subtypes,
1886 -- i.e. enumeration types that have at least one character literal.
1888 -- Is_Child_Unit (Flag73)
1889 -- Present in all entities. Set only for defining entities of program
1890 -- units that are child units (but False for subunits).
1892 -- Is_Class_Wide_Type (synthesized)
1893 -- Applies to all entities, true for class wide types and subtypes
1895 -- Is_Class_Wide_Equivalent_Type (Flag35)
1896 -- Present in record types and subtypes. Set to True, if the type acts
1897 -- as a class-wide equivalent type, i.e. the Equivalent_Type field of
1898 -- some class-wide subtype entity references this record type.
1900 -- Is_Compilation_Unit (Flag149)
1901 -- Present in all entities. Set if the entity is a package or subprogram
1902 -- entity for a compilation unit other than a subunit (since we treat
1903 -- subunits as part of the same compilation operation as the ultimate
1904 -- parent, we do not consider them to be separate units for this flag).
1906 -- Is_Completely_Hidden (Flag103)
1907 -- A flag set on an E_Discriminant entity. This flag can be set only
1908 -- for girder discriminants of untagged types. When set, the entity
1909 -- is a girder discriminant of a derived untagged type which is not
1910 -- directly visible in the derived type because the derived type or
1911 -- one of its ancestors have renamed the discriminants in the root
1912 -- type. Note that there are girder discriminants which are not
1913 -- Completely_Hidden (e.g. the discriminants of a root type).
1915 -- Is_Composite_Type (synthesized)
1916 -- Applies to all entities, true for all composite types and
1917 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
1918 -- not both) is true of any type.
1920 -- Is_Concurrent_Record_Type (Flag20)
1921 -- Present in record types and subtypes. Set if the type was created
1922 -- by the expander to represent a task or protected type. For every
1923 -- concurrent type, such as record type is constructed, and task and
1924 -- protected objects are instances of this record type at runtime
1925 -- (Gigi will replace declarations of the concurrent type using the
1926 -- declarations of the corresponding record type). See package Exp_Ch9
1927 -- for further details.
1929 -- Is_Concurrent_Type (synthesized)
1930 -- Applies to all entities, true for task types and subtypes and
1931 -- for protected types and subtypes.
1933 -- Is_Constrained (Flag12)
1934 -- Present in types or subtypes which may have index, discriminant
1935 -- or range constraint (i.e. array types and subtypes, record types
1936 -- and subtypes, string types and subtypes, and all numeric types).
1937 -- Set if the type or subtype is constrained.
1939 -- Is_Constr_Subt_For_U_Nominal (Flag80)
1940 -- Present in all types and subtypes. Set true only for the constructed
1941 -- subtype of an object whose nominal subtype is unconstrained. Note
1942 -- that the constructed subtype itself will be constrained.
1944 -- Is_Constr_Subt_For_UN_Aliased (Flag141)
1945 -- This flag can only be set if Is_Constr_Subt_For_U_Nominal is set. It
1946 -- indicates that in addition the object concerned is aliased. This flag
1947 -- is used by Gigi to determine whether a template must be constructed.
1949 -- Is_Constructor (Flag76)
1950 -- Present in function and procedure entities. Set if a pragma
1951 -- CPP_Constructor applies to the subprogram.
1953 -- Is_Controlled (Flag42) [base type only]
1954 -- Present in all type entities. Indicates that the type is controlled,
1955 -- i.e. is either a descendant of Ada.Finalization.Controlled or of
1956 -- Ada.Finalization.Limited_Controlled.
1958 -- Is_Controlling_Formal (Flag97)
1959 -- Present in all Formal_Kind entity. Marks the controlling parameters
1960 -- of dispatching operations.
1962 -- Is_CPP_Class (Flag74)
1963 -- Present in all type entities, set only for tagged types to which a
1964 -- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied.
1966 -- Is_Decimal_Fixed_Point_Type (synthesized)
1967 -- Applies to all type entities, true for decimal fixed point
1968 -- types and subtypes.
1970 -- Is_Derived_Type (synthesized)
1971 -- Applies to all entities. Determine if given entity is a derived type.
1972 -- Always false if argument is not a type.

1975 -- Applies to all entities, true for all discrete types and subtypes
1977 -- Is_Discrete__Or_Fixed_Point_Type (synthesized)
1978 -- Applies to all entities, true for all discrete types and subtypes

1983 -- creates to compute discriminant-dependent dynamic size/offset values.
1985 -- Is_Dispatching_Operation (Flag6)
1986 -- Present in all entities. Set true for procedures, functions,
1987 -- generic procedures and generic functions if the corresponding
1988 -- operation is dispatching.
1990 -- Is_Dynamic_Scope (synthesized)
1991 -- Applies to all Entities. Returns True if the entity is a dynamic
1992 -- scope (i.e. a block, subprogram, task_type, entry
1993 -- or extended return statement).
1995 -- Is_Elementary_Type (synthesized)
1996 -- Applies to all entities, true for all elementary types and
1997 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
1998 -- not both) is true of any type.
2000 -- Is_Eliminated (Flag124)
2001 -- Present in type entities, subprogram entities, and object entities.
2002 -- Indicates that the corresponding entity has been eliminated by use
2003 -- of pragma Eliminate. Also used to mark subprogram entities whose
2004 -- declaration and body are within unreachable code that is removed.
2006 -- Is_Enumeration_Type (synthesized)
2007 -- Present in all entities, true for enumeration types and subtypes
2009 -- Is_Entry (synthesized)
2010 -- Applies to all entities, True only for entry and entry family
2011 -- entities and False for all other entity kinds.
2013 -- Is_Entry_Formal (Flag52)
2014 -- Present in all entities. Set only for entry formals (which can
2015 -- only be in, in-out or out parameters). This flag is used to speed
2016 -- up the test for the need to replace references in Exp_Ch2.
2018 -- Is_Exported (Flag99)
2019 -- Present in all entities. Set if the entity is exported. For now we
2020 -- only allow the export of constants, exceptions, functions, procedures
2021 -- and variables, but that may well change later on. Exceptions can only
2022 -- be exported in the OpenVMS and Java VM implementations of GNAT.
2024 -- Is_First_Subtype (Flag70)
2025 -- Present in all entities. True for first subtypes (RM 3.2.1(6)),
2026 -- i.e. the entity in the type declaration that introduced the type.
2027 -- This may be the base type itself (e.g. for record declarations and
2028 -- enumeration type declarations), or it may be the first subtype of
2029 -- an anonymous base type (e.g. for integer type declarations or
2030 -- constrained array declarations).
2032 -- Is_Fixed_Point_Type (synthesized)
2033 -- Applies to all entities, true for decimal and ordinary fixed
2034 -- point types and subtypes
2036 -- Is_Floating_Point_Type (synthesized)
2037 -- Applies to all entities, true for float types and subtypes
2039 -- Is_Formal (synthesized)
2040 -- Applies to all entities, true for IN, IN OUT and OUT parameters
2042 -- Is_Formal_Object (synthesized)
2043 -- Applies to all entities, true for generic IN and IN OUT parameters
2045 -- Is_Formal_Subprogram (Flag111)
2046 -- Defined on all entities, true for generic formal subprograms.
2048 -- Is_For_Access_Subtype (Flag118)
2049 -- Present in E_Private_Subtype and E_Record_Subtype entities.
2050 -- Means the sole purpose of the type is to be designated by an
2051 -- Access_Subtype and hence should not be expanded into components
2052 -- because the type may not have been found or frozen yet.
2054 -- Is_Frozen (Flag4)
2055 -- Present in all type entities. Set if the type has been frozen.
2057 -- Is_Generic_Actual_Type (Flag94)
2058 -- Present in the subtype declaration that renames the generic formal
2059 -- as a subtype of the actual. Guarantees that the subtype is not static
2060 -- within the instance.
2062 -- Is_Generic_Instance (Flag130)
2063 -- Present in all entities. Set to indicate that the entity is an
2064 -- instance of a generic unit, or a formal package (which is an instance
2065 -- of the template).
2067 -- Is_Generic_Subprogram (synthesized)
2068 -- Applies to all entities. Yields True for a generic subprogram
2069 -- (generic function, generic subprogram), False for all other entities.
2071 -- Is_Generic_Type (Flag13)
2072 -- Present in all types and subtypes. Set for types which are generic
2073 -- formal types. Such types have an Ekind that corresponds to their
2074 -- classification, so the Ekind cannot be used to identify generic types.
2076 -- Is_Generic_Unit (synthesized)
2077 -- Applies to all entities. Yields True for a generic unit (generic
2078 -- package, generic function, generic procedure), and False for all
2081 -- Is_Hidden (Flag57)
2082 -- Present in all entities. Set true for all entities declared in the
2083 -- private part or body of a package. Also marks generic formals of a
2084 -- formal package declared without a box. For library level entities,
2085 -- this flag is set if the entity is not publicly visible.
2087 -- Is_Hidden_Open_Scope (Flag171)
2088 -- Present in all entities. Set true for a scope that contains the
2089 -- instantiation of a child unit, and whose entities are not visible
2090 -- during analysis of the instance.
2092 -- Is_Immediately_Visible (Flag7)
2093 -- Present in all entities. Set if entity is immediately visible, i.e.
2094 -- is defined in some currently open scope (RM 8.3(4)).
2096 -- Is_Imported (Flag24)
2097 -- Present in all entities. Set if the entity is imported. For now we
2098 -- only allow the import of exceptions, functions, procedures, packages.
2099 -- and variables. Exceptions can only be imported in the OpenVMS and
2100 -- Java VM implementations of GNAT. Packages and types can only be
2101 -- imported in the Java VM implementation.
2103 -- Is_Incomplete_Or_Private_Type (synthesized)
2104 -- Applies to all entities, true for private and incomplete types
2106 -- Is_Incomplete_Type (synthesized)
2107 -- Applies to all entities, true for incomplete types and subtypes
2109 -- Is_Indefinite_Subtype (synthesized)
2110 -- Applies to all entities for types and subtypes. Determines if given
2111 -- entity is an unconstrained array type or subtype, a discriminated
2112 -- record type or subtype with no initial discriminant values or a
2113 -- class wide type or subtype.
2115 -- Is_Inlined (Flag11)
2116 -- Present in all entities. Set for functions and procedures which are
2117 -- to be inlined. For subprograms created during expansion, this flag
2118 -- may be set directly by the expander to request inlining. Also set
2119 -- for packages that contain inlined subprograms, whose bodies must be
2120 -- be compiled. Is_Inlined is also set on generic subprograms and is
2121 -- inherited by their instances. It is also set on the body entities
2122 -- of inlined subprograms. See also Has_Pragma_Inline.
2124 -- Is_Instantiated (Flag126)
2125 -- Present in generic packages and generic subprograms. Set if the unit
2126 -- is instantiated from somewhere in the extended main source unit. This
2127 -- flag is used to control warnings about the unit being uninstantiated.
2128 -- Also set in a package that is used as an actual for a generic package
2129 -- formal in an instantiation. Also set on a parent instance, in the
2130 -- instantiation of a child, which is implicitly declared in the parent.
2132 -- Is_Integer_Type (synthesized)
2133 -- Applies to all entities, true for integer types and subtypes
2135 -- Is_Interface (Flag186)
2136 -- Present in record types and subtypes to indicate that the current
2137 -- entity corresponds with an abstract interface. Because abstract
2138 -- interfaces are conceptually a special kind of abstract tagged types
2139 -- we represent them by means of tagged record types and subtypes
2140 -- marked with this attribute. This allows us to reuse most of the
2141 -- compiler support for abstract tagged types to implement interfaces
2142 -- (Ada 2005: AI-251).
2144 -- Is_Internal (Flag17)
2145 -- Present in all entities. Set to indicate an entity created during
2146 -- semantic processing (e.g. an implicit type, or a temporary). The
2147 -- only current use of this flag is to indicate that temporaries
2148 -- generated for the result of an inlined function call need not be
2149 -- initialized, even when scalars are initialized or normalized.
2151 -- Is_Interrupt_Handler (Flag89)
2152 -- Present in procedures. Set if a pragma Interrupt_Handler applies
2153 -- to the procedure. The procedure must be parameterless, and on all
2154 -- targets except AAMP it must be a protected procedure.
2156 -- Is_Intrinsic_Subprogram (Flag64)
2157 -- Present in functions and procedures. It is set if a valid pragma
2158 -- Interface or Import is present for this subprogram specifying pragma
2159 -- Intrinsic. Valid means that the name and profile of the subprogram
2160 -- match the requirements of one of the recognized intrinsic subprograms
2161 -- (see package Sem_Intr for details). Note: the value of Convention for
2162 -- such an entity will be set to Convention_Intrinsic, but it is the
2163 -- setting of Is_Intrinsic_Subprogram, NOT simply having convention set
2164 -- to intrinsic, which causes intrinsic code to be generated.
2166 -- Is_Itype (Flag91)
2167 -- Present in all entities, set for Itypes. If it is set, then the
2168 -- declaration for the type does not appear explicitly in the tree.
2169 -- Instead gigi will elaborate the type when it is first used.
2170 -- Has_Delayed_Freeze can be set for Itypes, and the meaning is that
2171 -- the first use (the one which causes the type to be defined) will
2172 -- be the freeze node. Note that an important restriction on Itypes
2173 -- is that the first use of such a type (the one that causes it to be
2174 -- defined) must be in the same scope as the type.
2176 -- Is_Known_Non_Null (Flag37)
2177 -- Present in all entities. Relevant (and can be set True) only for
2178 -- objects of an access type. It is set if the object is currently
2179 -- known to have a non-null value (meaning that no access checks
2180 -- are needed). The indication can for example come from assignment
2181 -- of an access parameter or an allocator whose value is known non-null.
2183 -- Note: this flag is set according to the sequential flow of the
2184 -- program, watching the current value of the variable. However,
2185 -- this processing can miss cases of changing the value of an aliased
2186 -- or constant object, so even if this flag is set, it should not
2187 -- be believed if the variable is aliased or volatile. It would
2188 -- be a little neater to avoid the flag being set in the first
2189 -- place in such cases, but that's trickier, and there is only
2190 -- one place that tests the value anyway.
2192 -- The flag is dynamically set and reset as semantic analysis and
2193 -- expansion proceeds. Its value is meaningless once the tree is
2194 -- fully constructed, since it simply indicates the last state.
2195 -- Thus this flag has no meaning to the back end.
2197 -- Is_Known_Null (Flag204)
2198 -- Present in all entities. Relevant (and can be set True) only for
2199 -- objects of an access type. It is set if the object is currently known
2200 -- to have a null value (meaning that a dereference will surely raise
2201 -- constraint error exception). The indication can come from an
2202 -- assignment or object declaration.
2204 -- The comments above about sequential flow and aliased and volatile for
2205 -- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag.
2207 -- Is_Known_Valid (Flag170)
2208 -- Present in all entities. Relevant for types (and subtype) and
2209 -- for objects (and enumeration literals) of a discrete type.
2211 -- The purpose of this flag is to implement the requirement stated
2212 -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
2213 -- values may not cause programs to become erroneous. See the function
2214 -- Exp_Util.Expr_Known_Valid for further details. Note that the setting
2215 -- is conservative, in the sense that if the flag is set, it must be
2216 -- right. If the flag is not set, nothing is known about the validity.
2218 -- For enumeration literals, the flag is always set, since clearly
2219 -- an enumeration literal represents a valid value. Range checks
2220 -- where necessary will ensure that this valid value is appropriate.
2222 -- For objects, the flag indicates the state of knowledge about the
2223 -- current value of the object. This may be modified during expansion,
2224 -- and thus the final value is not relevant to gigi.
2226 -- For types and subtypes, the flag is set if all possible bit patterns
2227 -- of length Object_Size (i.e. Esize of the type) represent valid values
2228 -- of the type. In general for such tytpes, all values are valid, the
2229 -- only exception being the case where an object of the type has an
2230 -- explicit size that is greater than Object_Size.
2232 -- For non-discrete objects, the setting of the Is_Known_Valid flag is
2233 -- not defined, and is not relevant, since the considerations of the
2234 -- requirement in (RM 13.9.1(9-11)) do not apply.
2236 -- The flag is dynamically set and reset as semantic analysis and
2237 -- expansion proceeds. Its value is meaningless once the tree is
2238 -- fully constructed, since it simply indicates the last state.
2239 -- Thus this flag has no meaning to the back end.
2241 -- Is_Limited_Composite (Flag106)
2242 -- Present in all entities. True for composite types that have a
2243 -- limited component. Used to enforce the rule that operations on
2244 -- the composite type that depend on the full view of the component
2245 -- do not become visible until the immediate scope of the composite
2246 -- type itself (RM 7.3.1 (5)).
2248 -- Is_Limited_Interface (Flag197)
2249 -- Present in record types and subtypes. True for interface types, if
2250 -- interface is declared limited, task, protected, or synchronized, or
2251 -- is derived from a limited interface.
2253 -- Is_Limited_Record (Flag25)
2254 -- Present in all entities. Set to true for record (sub)types if the
2255 -- record is declared to be limited. Note that this flag is not set
2256 -- simply because some components of the record are limited.
2258 -- Is_Limited_Type (synthesized)
2259 -- Applies to all entities. True if entity is a limited type (limited
2260 -- private type, limited interface type, task type, protected type,
2261 -- composite containing a limited component, or a subtype of any of
2264 -- Is_Machine_Code_Subprogram (Flag137)
2265 -- Present in subprogram entities. Set to indicate that the subprogram
2266 -- is a machine code subprogram (i.e. its body includes at least one
2267 -- code statement). Also indicates that all necessary semantic checks
2268 -- as required by RM 13.8(3) have been performed.
2270 -- Is_Modular_Integer_Type (synthesized)
2271 -- Applies to all entities. True if entity is a modular integer type
2273 -- Is_Non_Static_Subtype (Flag109)
2274 -- This flag is present in all type and subtype entities. It is set in
2275 -- some (but not all) cases in which a subtype is known to be non-static.
2276 -- Before this flag was added, the computation of whether a subtype was
2277 -- static was entirely synthesized, by looking at the bounds, and the
2278 -- immediate subtype parent. However, this method does not work for some
2279 -- Itypes that have no parent set (and the only way to find the immediate
2280 -- subtype parent is to go through the tree). For now, this flay is set
2281 -- conservatively, i.e. if it is set then for sure the subtype is non-
2282 -- static, but if it is not set, then the type may or may not be static.
2283 -- Thus the test for a static subtype is that this flag is clear AND
2284 -- that the bounds are static AND that the parent subtype (if available
2285 -- to be tested) is static. Eventually we should make sure this flag
2286 -- is always set right, at which point, these comments can be removed,
2287 -- and the tests for static subtypes greatly simplified.
2289 -- Is_Null_Init_Proc (Flag178)
2290 -- Present in procedure entities. Set for generated init proc procedures
2291 -- (used to initialize composite types), if the code for the procedure
2292 -- is null (i.e. is a return and nothing else). Such null initialization
2293 -- procedures are generated in case some client is compiled using the
2294 -- Initialize_Scalars pragma, generating a call to this null procedure,
2295 -- but there is no need to call such procedures within a compilation
2296 -- unit, and this flag is used to suppress such calls.
2298 -- Is_Numeric_Type (synthesized)
2299 -- Applies to all entities, true for all numeric types and subtypes
2300 -- (integer, fixed, float).
2302 -- Is_Object (synthesized)
2303 -- Applies to all entities, true for entities representing objects,
2304 -- including generic formal parameters.
2306 -- Is_Obsolescent (Flag153)
2307 -- Present in all entities. Set for any entity for which a valid pragma
2308 -- Obsolescent applies.
2310 -- Is_Optional_Parameter (Flag134)
2311 -- Present in parameter entities. Set if the parameter is specified as
2312 -- optional by use of a First_Optional_Parameter argument to one of the
2313 -- extended Import pragmas. Can only be set for OpenVMS versions of GNAT.
2315 -- Is_Ordinary_Fixed_Point_Type (synthesized)
2316 -- Applies to all entities, true for ordinary fixed point types
2319 -- Is_Overriding_Operation (Flag39)
2320 -- Present in subprograms. Set if the subprogram is a primitive
2321 -- operation of a derived type, that overrides an inherited operation.
2323 -- Is_Package_Or_Generic_Package (synthesized)
2324 -- Applies to all entities. True for packages and generic packages.
2325 -- False for all other entities.
2327 -- Is_Package_Body_Entity (Flag160)
2328 -- Present in all entities. Set for entities defined at the top level
2329 -- of a package body. Used to control externally generated names.
2331 -- Is_Packed (Flag51) [implementation base type only]
2332 -- Present in all type entities. This flag is set only for record and
2333 -- array types which have a packed representation. There are three
2334 -- cases which cause packing:
2336 -- 1. Explicit use of pragma Pack for an array of package components
2337 -- 2. Explicit use of pragma Pack to pack a record
2338 -- 4. Setting Component_Size of an array to a bit-packable value
2339 -- 3. Indexing an array with a non-standard enumeration type.
2341 -- For records, Is_Packed is always set if Has_Pack_Pragma is set,
2342 -- and can also be set on its own in a derived type which inherited
2343 -- its packed status.
2345 -- For arrays, Is_Packed is set if an array is bit packed (i.e. the
2346 -- component size is known at compile time and is 1-7, 9-15 or 17-31),
2347 -- or if the array has one or more index types that are enumeration
2348 -- types with non-standard representations (in GNAT, we store such
2349 -- arrays compactly, using the Pos of the enumeration type value).
2351 -- As for the case of records, Is_Packed can be set on its own for a
2352 -- derived type, with the same dual before/after freeze meaning.
2353 -- Is_Packed can also be set as the result of an explicit component
2354 -- size clause that specifies an appropriate component size.
2356 -- In the bit packed array case, Is_Bit_Packed_Array will be set in
2357 -- the bit packed case once the array type is frozen.
2359 -- Before an array type is frozen, Is_Packed will always be set if
2360 -- Has_Pack_Pragma is set. Before the freeze point, it is not possible
2361 -- to know the component size, since the component type is not frozen
2362 -- until the array type is frozen. Thus Is_Packed for an array type
2363 -- before it is frozen means that packed is required. Then if it turns
2364 -- out that the component size is not suitable for bit packing, the
2365 -- Is_Packed flag gets turned off.
2367 -- Is_Packed_Array_Type (Flag138)
2368 -- Present in all entities. This flag is set on the entity for the type
2369 -- used to implement a packed array (either a modular type, or a subtype
2370 -- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
2371 -- if the type appears in the Packed_Array_Type field of some other type
2372 -- entity. It is used by Gigi to activate the special processing for such
2373 -- types (unchecked conversions that would not otherwise be allowed are
2374 -- allowed for such types). If the Is_Packed_Array_Type flag is set in
2375 -- an entity, then the Original_Array_Type field of this entity points
2376 -- to the original array type for which this is the packed array type.
2378 -- Is_Potentially_Use_Visible (Flag9)
2379 -- Present in all entities. Set if entity is potentially use visible,
2380 -- i.e. it is defined in a package that appears in a currently active
2381 -- use clause (RM 8.4(8)). Note that potentially use visible entities
2382 -- are not necessarily use visible (RM 8.4(9-11)).
2384 -- Is_Preelaborated (Flag59)
2385 -- Present in all entities, set in E_Package and E_Generic_Package
2386 -- entities to which a pragma Preelaborate is applied, and also in
2387 -- all entities within such packages. Note that the fact that this
2388 -- flag is set does not necesarily mean that no elaboration code is
2389 -- generated for the package.
2391 -- Is_Primitive_Wrapper (Flag195)
2392 -- Present in E_Procedures. Primitive wrappers are Expander-generated
2393 -- procedures that wrap entries of protected or task types implementing
2394 -- a limited interface.
2396 -- Is_Private_Composite (Flag107)
2397 -- Present in composite types that have a private component. Used to
2398 -- enforce the rule that operations on the composite type that depend
2399 -- on the full view of the component, do not become visible until the
2400 -- immediate scope of the composite type itself (7.3.1 (5)). Both this
2401 -- flag and Is_Limited_Composite are needed.
2403 -- Is_Private_Descendant (Flag53)
2404 -- Present in entities that can represent library units (packages,
2405 -- functions, procedures). Set if the library unit is itself a private
2406 -- child unit, or if it is the descendent of a private child unit.
2408 -- Is_Private_Type (synthesized)
2409 -- Applies to all entities, true for private types and subtypes,
2410 -- as well as for record with private types as subtypes
2412 -- Is_Protected_Interface (Flag198)
2413 -- Present in types that are interfaces. True if interface is declared
2414 -- protected, or is derived from protected interfaces.
2416 -- Is_Protected_Type (synthesized)
2417 -- Applies to all entities, true for protected types and subtypes
2419 -- Is_Public (Flag10)
2420 -- Present in all entities. Set to indicate that an entity defined in
2421 -- one compilation unit can be referenced from other compilation units.
2422 -- If this reference causes a reference in the generated variable, for
2423 -- example in the case of a variable name, then Gigi will generate an
2424 -- appropriate external name for use by the linker.
2426 -- Is_Protected_Private (synthesized)
2427 -- Applies to a record component. Returns true if this component
2428 -- is used to represent a private declaration of a protected type.
2430 -- Is_Protected_Record_Type (synthesized)
2431 -- Applies to all entities, true if Is_Concurrent_Record_Type
2432 -- Corresponding_Concurrent_Type is a protected type.
2435 -- Present in all entities. Set in all entities of a unit to which a
2436 -- pragma Pure is applied, and also set for the entity of the unit
2437 -- itself. In addition, this flag may be set for any other functions
2438 -- or procedures that are known to be side effect free, so in the case
2439 -- of subprograms, the Is_Pure flag may be used by the optimizer to
2440 -- imply that it can assume freedom from side effects (other than those
2441 -- resulting from assignment to out parameters, or to objects designated
2442 -- by access parameters).
2444 -- Is_Pure_Unit_Access_Type (Flag189)
2445 -- Present in access type and subtype entities. Set if the type or
2446 -- subtype appears in a pure unit. Used to give an error message at
2447 -- freeze time if the access type has a storage pool.
2449 -- Is_Real_Type (synthesized)
2450 -- Applies to all entities, true for real types and subtypes
2452 -- Is_Record_Type (synthesized)
2453 -- Applies to all entities, true for record types and subtypes,
2454 -- includes class-wide types and subtypes (which are also records)
2456 -- Is_Remote_Call_Interface (Flag62)
2457 -- Present in all entities, set in E_Package and E_Generic_Package
2458 -- entities to which a pragma Remote_Call_Interace is applied, and
2459 -- also in all entities within such packages.
2461 -- Is_Remote_Types (Flag61)
2462 -- Present in all entities, set in E_Package and E_Generic_Package
2463 -- entities to which a pragma Remote_Types is applied, and also in
2464 -- all entities within such packages.
2466 -- Is_Renaming_Of_Object (Flag112)
2467 -- Present in all entities, set only for a variable or constant for
2468 -- which the Renamed_Object field is non-empty and for which the
2469 -- renaming is handled by the front end, by macro substitution of
2470 -- a copy of the (evaluated) name tree whereever the variable is used.
2472 -- Is_Inherently_Limited_Type (synthesized)
2473 -- Applies to all type entities. True if the type is "inherently"
2474 -- limited (i.e. cannot become nonlimited). From the Ada 2005
2475 -- RM-7.5(8.1/2), "a type with a part that is of a task, protected, or
2476 -- explicitly limited record type". These are the types that are defined
2477 -- as return-by-reference types in Ada 95 (see RM95-6.5(11-16)). In Ada
2478 -- 2005, these are the types that require build-in-place for function
2479 -- calls. Note that build-in-place is allowed for other types, too.
2481 -- Is_Return_Object (Flag209)
2482 -- Applies to all object entities. True if the object is the return
2483 -- object of an extended_return_statement; False otherwise.
2485 -- Is_Scalar_Type (synthesized)
2486 -- Applies to all entities, true for scalar types and subtypes
2488 -- Is_Shared_Passive (Flag60)
2489 -- Present in all entities, set in E_Package and E_Generic_Package
2490 -- entities to which a pragma Shared_Passive is applied, and also in
2491 -- all entities within such packages.
2493 -- Is_Statically_Allocated (Flag28)
2494 -- Present in all entities. This can only be set True for exception,
2495 -- variable, constant, and type/subtype entities. If the flag is set,
2496 -- then the variable or constant must be allocated statically rather
2497 -- than on the local stack frame. For exceptions, the meaning is that
2498 -- the exception data should be allocated statically (and indeed this
2499 -- flag is always set for exceptions, since exceptions do not have
2500 -- local scope). For a type, the meaning is that the type must be
2501 -- elaborated at the global level rather than locally. No type marked
2502 -- with this flag may depend on a local variable, or on any other type
2503 -- which does not also have this flag set to True. For a variable or
2504 -- or constant, if the flag is set, then the type of the object must
2505 -- either be declared at the library level, or it must also have the
2506 -- flag set (since to allocate the oject statically, its type must
2507 -- also be elaborated globally).
2509 -- Is_Subprogram (synthesized)
2510 -- Applies to all entities, true for bodies of functions, procedures
2513 -- Is_String_Type (synthesized)
2514 -- Applies to all type entities. Determines if the given type is a
2515 -- string type, i.e. it is directly a string type or string subtype,
2516 -- or a string slice type, or an array type with one dimension and a
2517 -- component type that is a character type.
2519 -- Is_Synchronized_Interface (Flag199)
2520 -- Present in types that are interfaces. True if interface is declared
2521 -- synchronized, task, or protected, or is derived from a synchronized
2525 -- Present in E_Component. For regular tagged type this flag is set on
2526 -- the tag component (whose name is Name_uTag) and for CPP_Class tagged
2527 -- types, this flag marks the pointer to the main vtable (i.e. the one
2528 -- to be extended by derivation)
2530 -- Is_Tagged_Type (Flag55)
2531 -- Present in all entities, true for an entity for a tagged type.
2533 -- Is_Task_Interface (Flag200)
2534 -- Present in types that are interfaces. True is interface is declared
2535 -- as such, or if it is derived from task interfaces.
2537 -- Is_Task_Record_Type (synthesized)
2538 -- Applies to all entities, true if Is_Concurrent_Record_Type
2539 -- Corresponding_Concurrent_Type is a task type.
2541 -- Is_Task_Type (synthesized)
2542 -- Applies to all entities, true for task types and subtypes
2544 -- Is_True_Constant (Flag163)
2545 -- This flag is set in constants and variables which have an initial
2546 -- value specified but which are never assigned, partially or in the
2547 -- whole. For variables, it means that the variable was initialized
2548 -- but never modified, and hence can be treated as a constant by the
2549 -- code generator. For a constant, it means that the constant was not
2550 -- modified by generated code (e.g. to set a discriminant in an init
2551 -- proc). Assignments by user or generated code will reset this flag.
2553 -- Note: there is one situation in which the back end does not permit
2554 -- this flag to be set, even if no assignments are generated. This is
2555 -- the case of an object of a record or array type which is initialized
2556 -- with an aggregate, and is itself used as the expression initializing
2557 -- an atomic object, or the right hand side of an assignment to an atomic
2558 -- object. In this case the object must not have Is_True_Constant set,
2559 -- even though no assignments are generated (the reason for this is that
2560 -- the back end must not optimize the object away, because that would
2561 -- violate the restriction on aggregates in these positions).
2563 -- Is_Type (synthesized)
2564 -- Applies to all entities, true for a type entity
2566 -- Is_Unchecked_Union (Flag117) [implementation base type only]
2567 -- Present in all entities. Set only in record types to which the
2568 -- pragma Unchecked_Union has been validly applied.
2570 -- Is_Unsigned_Type (Flag144)
2571 -- Present in all types, but can be set only for discrete and fixed-point
2572 -- type and subtype entities. This flag is only valid if the entity is
2573 -- frozen. If set it indicates that the representation is known to be
2574 -- unsigned (i.e. that no negative values appear in the range). This is
2575 -- normally just a reflection of the lower bound of the subtype or base
2576 -- type, but there is one case in which the setting is non-obvious,
2577 -- namely the case of an unsigned subtype of a signed type from which
2578 -- a further subtype is obtained using variable bounds. This further
2579 -- subtype is still unsigned, but this cannot be determined by looking
2580 -- at its bounds or the bounds of the corresponding base type.
2582 -- Is_Valued_Procedure (Flag127)
2583 -- Present in procedure entities. Set if an Import_Valued_Procedure
2584 -- or Export_Valued_Procedure pragma applies to the procedure entity.
2586 -- Is_Visible_Child_Unit (Flag116)
2587 -- Present in compilation units that are child units. Once compiled,
2588 -- child units remain chained to the entities in the parent unit, and
2589 -- a separate flag must be used to indicate whether the names are
2590 -- visible by selected notation, or not.
2592 -- Is_Visible_Formal (Flag206)
2593 -- Present in all entities. Set for instances of the formals of a formal
2594 -- package. Indicates that the entity must be made visible in the body
2595 -- of the instance, to reproduce the visibility of the generic. This
2596 -- simplifies visibility settings in instance bodies.
2597 -- ??? confusion in abovecomments between being present and being set
2599 -- Is_VMS_Exception (Flag133)
2600 -- Present in all entities. Set only for exception entities where the
2601 -- exception was specified in an Import_Exception or Export_Exception
2602 -- pragma with the VMS option for Form. See description of these pragmas
2603 -- for details. This flag can only be set in OpenVMS versions of GNAT.
2605 -- Is_Volatile (Flag16)
2606 -- Present in all type entities, and also in constants, components and
2607 -- variables. Set if a pragma Volatile applies to the entity. Also set
2608 -- if pragma Shared or pragma Atomic applies to entity. In the case of
2609 -- private or incomplete types, this flag is set in both the private
2610 -- and full view. The flag is not set reliably on private subtypes,
2611 -- and is always retrieved from the base type (but this is not a base-
2612 -- type-only attribute because it applies to other entities). Note that
2613 -- the back end should use Treat_As_Volatile, rather than Is_Volatile
2614 -- to indicate code generation requirements for volatile variables.
2615 -- Similarly, any front end test which is concerned with suppressing
2616 -- optimizations on volatile objects should test Treat_As_Volatile
2617 -- rather than testing this flag.
2619 -- Is_Wrapper_Package (synthesized)
2620 -- Present in package entities. Indicates that the package has been
2621 -- created as a wrapper for a subprogram instantiation.
2623 -- Itype_Printed (Flag202)
2624 -- Set in Itypes if the Itype has been printed by Sprint. This is used to
2625 -- avoid printing an Itype more than once.
2627 -- Kill_Elaboration_Checks (Flag32)
2628 -- Present in all entities. Set by the expander to kill elaboration
2629 -- checks which are known not to be needed. Equivalent in effect to
2630 -- the use of pragma Supress (Elaboration_Checks) for that entity
2631 -- except that the effect is permanent and cannot be undone by a
2632 -- subsequent pragma Unsuppress.
2634 -- Kill_Range_Checks (Flag33)
2635 -- Present in all entities. Equivalent in effect to the use of pragma
2636 -- Supress (Range_Checks) for that entity except that the result is
2637 -- permanent and cannot be undone by a subsequent pragma Unsuppress.
2638 -- This is currently only used in one odd situation in Sem_Ch3 for
2639 -- record types, and it would be good to get rid of it???
2641 -- Kill_Tag_Checks (Flag34)
2642 -- Present in all entities. Set by the expander to kill elaboration
2643 -- checks which are known not to be needed. Equivalent in effect to
2644 -- the use of pragma Supress (Tag_Checks) for that entity except
2645 -- that the result is permanent and cannot be undone by a subsequent
2646 -- pragma Unsuppress.
2648 -- Last_Assignment (Node20)
2649 -- Present in entities for variables. Set for a local variable to point
2650 -- to the left side of an assignment statement assigning a value to the
2651 -- variable. Cleared if the value of the variable is referenced. Used to
2652 -- warn about dubious assignment statements whose value is not used.
2654 -- Last_Entity (Node20)
2655 -- Present in all entities which act as scopes to which a list of
2656 -- associated entities is attached (blocks, class subtypes and types,
2657 -- entries, functions, loops, packages, procedures, protected objects,
2658 -- record types and subtypes, private types, task types and subtypes).
2659 -- Points to a the last entry in the list of associated entities chained
2660 -- through the Next_Entity field. Empty if no entities are chained.
2662 -- Limited_View (Node23)
2663 -- Present in non-generic package entities that are not instances. Bona
2664 -- fide package with the limited-view list through the first_entity and
2665 -- first_private attributes. The elements of this list are the shadow
2666 -- entities created for the types and local packages that are declared
2667 -- in a package appearing in a limited_with clause (Ada 2005: AI-50217)
2669 -- Lit_Indexes (Node15)
2670 -- Present in enumeration types and subtypes. Non-empty only for the
2671 -- case of an enumeration root type, where it contains the entity for
2672 -- the generated indexes entity. See unit Exp_Imgv for full details of
2673 -- the nature and use of this entity for implkementing the Image and
2674 -- Value attributes for the enumeration type in question.
2676 -- Lit_Strings (Node16)
2677 -- Present in enumeration types and subtypes. Non-empty only for the
2678 -- case of an enumeration root type, where it contains the entity for
2679 -- the literals string entity. See unit Exp_Imgv for full details of
2680 -- the nature and use of this entity for implementing the Image and
2681 -- Value attributes for the enumeration type in question.
2683 -- Low_Bound_Known (Flag205)
2684 -- Present in all entities. Currently this can only be set True for
2685 -- formal parameter entries of a standard unconstrained one-dimensional
2686 -- array or string type, where the lower bound of the index type is zero
2687 -- or one. Indicates that the low bound is known to be equal to the lower
2688 -- bound of the index type (e.g. 1 for String, since the index type is
2689 -- Positive). This flag can only be set by a pragma Assert which
2690 -- specifies this. If this flag is set, warnings about assuming the index
2691 -- low bound to be zero or one are suppressed.
2693 -- Machine_Radix_10 (Flag84)
2694 -- Present in decimal types and subtypes, set if the Machine_Radix
2695 -- is 10, as the result of the specification of a machine radix
2696 -- representation clause. Note that it is possible for this flag
2697 -- to be set without having Has_Machine_Radix_Clause True. This
2698 -- happens when a type is derived from a type with a clause present.
2700 -- Master_Id (Node17)
2701 -- Present in access types and subtypes. Empty unless Has_Task is
2702 -- set for the designated type, in which case it points to the entity
2703 -- for the Master_Id for the access type master. Also set for access-to-
2704 -- limited-class-wide types whose root may be extended with task
2705 -- components, and for access-to-limited-interfaces because they can be
2706 -- used to reference tasks implementing such interface.
2708 -- Materialize_Entity (Flag168)
2709 -- Present in all entities. Set only for constant or renamed entities
2710 -- which should be materialized for debugging purposes. In the case of
2711 -- a constant, a memory location should be allocated containing the
2712 -- value. In the case of a renaming, a memory location containing the
2713 -- renamed address should be allocated.
2715 -- Mechanism (Uint8) (returned as Mechanism_Type)
2716 -- Present in functions and non-generic formal parameters. Indicates
2717 -- the mechanism to be used for the function return or for the formal
2718 -- parameter. See separate section on passing mechanisms. This field
2719 -- is also set (to the default value of zero) in a subprogram body
2720 -- entity but not used in this context.
2722 -- Modulus (Uint17) [base type only]
2723 -- Present in modular types. Contains the modulus. For the binary
2724 -- case, this will be a power of 2, but if Non_Binary_Modulus is
2725 -- set, then it will not be a power of 2.
2727 -- Must_Be_On_Byte_Boundary (Flag183)
2728 -- Present in entities for types and subtypes. Set if objects of
2729 -- the type must always be allocated on a byte boundary (more
2730 -- accurately a storage unit boundary). The front end checks that
2731 -- component clauses respect this rule, and the back end ensures
2732 -- that record packing does not violate this rule. Currently the
2733 -- flag is set only for packed arrays longer than 64 bits where
2734 -- the component size is not a power of 2.
2736 -- Must_Have_Preelab_Init (Flag208)
2737 -- Present in entities for types and subtypes. Set in the full type of a
2738 -- private type or subtype if a pragma Has_Preelaborable_Initialization
2739 -- is present for the private type. Used to check that the full type has
2740 -- preelaborable initialization at freeze time (this has to be deferred
2741 -- to the freeze point because of the rule about overriding Initialize).
2743 -- Needs_Debug_Info (Flag147)
2744 -- Present in all entities. Set if the entity requires debugging
2745 -- information to be generated. This is true of all entities that
2746 -- have Comes_From_Source set, and also transitively for entities
2747 -- associated with such components (e.g. their types). It is true
2748 -- for all entities in Debug_Generated_Code mode (-gnatD switch).
2749 -- This is the flag that the back end should check to determine
2750 -- whether or not to generate debugging information for an entity.
2752 -- Needs_No_Actuals (Flag22)
2753 -- Present in callable entities (subprograms, entries, access to
2754 -- subprograms) which can be called without actuals because all of
2755 -- their formals (if any) have default values. This flag simplifies the
2756 -- resolution of the syntactic ambiguity involving a call to these
2757 -- entities when the return type is an array type, and a call can be
2758 -- interpreted as an indexing of the result of the call. It is also
2759 -- used to resolve various cases of entry calls.
2761 -- Never_Set_In_Source (Flag115)
2762 -- Present in all entities, but relevant only for variables and
2763 -- parameters. This flag is set if the object is never assigned
2764 -- a value in user source code, either by assignment or by the
2765 -- use of an initial value, or by some other means.
2767 -- This flag is only for the purposes of issuing warnings, it must not
2768 -- be used by the code generator to indicate that the variable is in
2769 -- fact a constant, since some assignments in generated code do not
2770 -- count (for example, the call to an init proc to assign some but
2771 -- not all of the fields in a partially initialized record). The code
2772 -- generator should instead use the flag Is_True_Constant.
2774 -- For the purposes of this warning, the default assignment of
2775 -- access variables to null is not considered the assignment of
2776 -- of a value (so the warning can be given for code that relies
2777 -- on this initial null value, when no other value is ever set).
2779 -- In variables and out parameters, if this flag is set after full
2780 -- processing of the corresponding declarative unit, it indicates that
2781 -- the variable or parameter was never set, and a warning message can
2784 -- Note: this flag is initially set, and then cleared on encountering
2785 -- any construct that might conceivably legitimately set the value.
2786 -- Thus during the analysis of a declarative region and its associated
2787 -- statement sequence, the meaning of the flag is "not set yet", and
2788 -- once this analysis is complete the flag means "never assigned".
2790 -- Note: for variables appearing in package declarations, this flag
2791 -- is never set. That is because there is no way to tell if some
2792 -- client modifies the variable (or in the case of variables in the
2793 -- private part, if some child unit modifies the variables).
2795 -- Note: in the case of renamed objects, the flag must be set in the
2796 -- ultimate renamed object. Clients noting a possible modification
2797 -- should use the Note_Possible_Modification procedure in Sem_Util
2798 -- rather than Set_Never_Set_In_Source precisely to deal properly with
2799 -- the renaming possibility.
2801 -- Next_Component (synthesized)
2802 -- Applies to record components. Returns the next component by following
2803 -- the chain of declared entities until one is found which corresponds to
2804 -- a component (Ekind is E_Component). Any internal types generated from
2805 -- the subtype indications of the record components are skipped. Returns
2806 -- Empty if no more components.
2808 -- Next_Component_Or_Discriminant (synthesized)
2809 -- Similar to Next_Component, but includes components and discriminants
2810 -- so the input can have either E_Component or E_Discriminant, and the
2811 -- same is true for the result. Returns Empty if no more components or
2812 -- discriminants in the record.
2814 -- Next_Discriminant (synthesized)
2815 -- Applies to discriminants returned by First/Next_Discriminant.
2816 -- Returns the next language-defined (ie: perhaps non-girder)
2817 -- discriminant by following the chain of declared entities as long as
2818 -- the kind of the entity corresponds to a discriminant. Note that the
2819 -- discriminants might be the only components of the record.
2820 -- Returns Empty if there are no more.
2822 -- Next_Entity (Node2)
2823 -- Present in all entities. The entities of a scope are chained, with
2824 -- the head of the list being in the First_Entity field of the scope
2825 -- entity. All entities use the Next_Entity field as a forward pointer
2826 -- for this list, with Empty indicating the end of the list. Since this
2827 -- field is in the base part of the entity, the access routines for this
2828 -- field are in Sinfo.
2830 -- Next_Formal (synthesized)
2831 -- Applies to the entity for a formal parameter. Returns the next
2832 -- formal parameter of the subprogram or subprogram type. Returns
2833 -- Empty if there are no more formals.
2835 -- Next_Formal_With_Extras (synthesized)
2836 -- Applies to the entity for a formal parameter. Returns the next
2837 -- formal parameter of the subprogram or subprogram type. Returns
2838 -- Empty if there are no more formals. The list returned includes
2839 -- all the extra formals (see description of Extra_Formal field)
2841 -- Next_Girder_Discriminant (synthesized)
2842 -- Applies to discriminants. Set only for a discriminant returned by
2843 -- a call to First/Next_Girder_Discriminant. Returns next girder
2844 -- discriminant, if there are more (see complete description in
2845 -- First_Girder_Discriminant), or Empty if there are no more.
2847 -- Next_Index (synthesized)
2848 -- Applies to array types and subtypes and to string types and
2849 -- subtypes. Yields the next index. The first index is obtained by
2850 -- using the First_Index attribute, and then subsequent indexes are
2851 -- obtained by applying Next_Index to the previous index. Empty is
2852 -- returned to indicate that there are no more indexes. Note that
2853 -- unlike most attributes in this package, Next_Index applies to
2854 -- nodes for the indexes, not to entities.
2856 -- Next_Inlined_Subprogram (Node12)
2857 -- Present in subprograms. Used to chain inlined subprograms used in
2858 -- the current compilation, in the order in which they must be compiled
2859 -- by Gigi to insure that all inlinings are performed.
2861 -- Next_Literal (synthesized)
2862 -- Applies to enumeration literals, returns the next literal, or
2863 -- Empty if applied to the last literal. This is actually a synonym
2864 -- for Next, but its use is preferred in this context.
2866 -- Next_Tag_Component (synthesized)
2867 -- Applies to components of tagged record types. Given a _Tag field
2868 -- of a record, returns the next _Tag field in this record.
2870 -- Non_Binary_Modulus (Flag58) [base type only]
2871 -- Present in modular integer types. Set if the modulus for the type
2872 -- is other than a power of 2.
2874 -- Non_Limited_View (Node17)
2875 -- Present in incomplete types that are the shadow entities created
2876 -- when analyzing a limited_with_clause (Ada 2005: AI-50217). Points to
2877 -- the defining entity in the original declaration.
2879 -- Nonzero_Is_True (Flag162) [base type only]
2880 -- Present in enumeration types. True if any non-zero value is to be
2881 -- interpreted as true. Currently this is set true for derived Boolean
2882 -- types which have a convention of C, C++ or Fortran.
2884 -- No_Pool_Assigned (Flag131) [root type only]
2885 -- Present in access types. Set if a storage size clause applies to
2886 -- the variable with a compile time known value of zero. This flag is
2887 -- used to generate warnings if any attempt is made to allocate or free
2888 -- an instance of such an access type. This is set only in the root
2889 -- type, since derived types must have the same pool.
2891 -- No_Return (Flag113)
2892 -- Present in all entities. Always false except in the case of procedures
2893 -- and generic procedures for which a pragma No_Return is given.
2895 -- Normalized_First_Bit (Uint8)
2896 -- Present in components and discriminants. Indicates the normalized
2897 -- value of First_Bit for the component, i.e. the offset within the
2898 -- lowest addressed storage unit containing part or all of the field.
2899 -- Set to No_Uint if no first bit position is assigned yet.
2901 -- Normalized_Position (Uint14)
2902 -- Present in components and discriminants. Indicates the normalized
2903 -- value of Position for the component, i.e. the offset in storage
2904 -- units from the start of the record to the lowest addressed storage
2905 -- unit containing part or all of the field.
2907 -- Normalized_Position_Max (Uint10)
2908 -- Present in components and discriminants. For almost all cases, this
2909 -- is the same as Normalized_Position. The one exception is for the case
2910 -- of a discriminated record containing one or more arrays whose length
2911 -- depends on discriminants. In this case, the Normalized_Position_Max
2912 -- field represents the maximum possible value of Normalized_Position
2913 -- assuming min/max values for discriminant subscripts in all fields.
2914 -- This is used by Layout in front end layout mode to properly computed
2915 -- the maximum size such records (needed for allocation purposes when
2916 -- there are default discriminants, and also for the 'Size value).
2918 -- No_Strict_Aliasing (Flag136) [base type only]
2919 -- Present in access types. Set to direct the back end to avoid any
2920 -- optimizations based on an assumption about the aliasing status of
2921 -- objects designated by the access type. For the case of the gcc
2922 -- back end, the effect is as though all references to objects of
2923 -- the type were compiled with -fno-strict-aliasing. This flag is
2924 -- set if an unchecked conversion with the access type as a target
2925 -- type occurs in the same source unit as the declaration of the
2926 -- access type, or if an explicit pragma No_Strict_Aliasing applies.
2928 -- Number_Dimensions (synthesized)
2929 -- Applies to array types and subtypes. Returns the number of dimensions
2930 -- of the array type or subtype as a value of type Pos.
2932 -- Number_Discriminants (synthesized)
2933 -- Applies to all types with discriminants. Yields the number of
2934 -- discriminants as a value of type Pos.
2936 -- Number_Entries (synthesized)
2937 -- Applies to concurrent types. Returns the number of entries that are
2938 -- declared within the task or protected definition for the type.
2940 -- Number_Formals (synthesized)
2941 -- Applies to subprograms and subprogram types. Yields the number of
2942 -- formals as a value of type Pos.
2944 -- Obsolescent_Warning (Node24)
2945 -- Present in all entities. Set non-empty only if a pragma Obsolescent
2946 -- applying to the entity had a string argument, in which case it records
2947 -- the contents of the corresponding string literal node. This field is
2948 -- only accessed if the flag Is_Obsolescent is set.
2950 -- Original_Array_Type (Node21)
2951 -- Present in modular types and array types and subtypes. Set only
2952 -- if the Is_Packed_Array_Type flag is set, indicating that the type
2953 -- is the implementation type for a packed array, and in this case it
2954 -- points to the original array type for which this is the packed
2955 -- array implementation type.
2957 -- Object_Ref (Node17)
2958 -- Present in protected bodies. This is an implicit prival for the
2959 -- Protection object associated with a protected object. See Prival
2960 -- for further details on the use of privals.
2962 -- Original_Record_Component (Node22)
2963 -- Present in components, including discriminants. The usage depends
2964 -- on whether the record is a base type and whether it is tagged.
2966 -- In base tagged types:
2967 -- When the component is inherited in a record extension, it points
2968 -- to the original component (the entity of the ancestor component
2969 -- which is not itself inherited) otherwise it points to itself.
2970 -- Gigi uses this attribute to implement the automatic dereference in
2971 -- the extension and to apply the transformation:
2973 -- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
2975 -- In base non-tagged types:
2976 -- Always points to itself except for non-girder discriminants, where
2977 -- it points to the girder discriminant it renames.
2979 -- In subtypes (tagged and untagged):
2980 -- Points to the component in the base type.
2982 -- Overridden_Operation (Node26)
2983 -- Present in subprograms. For overriding operations, points to the
2984 -- user-defined parent subprogram that is being overridden.
2986 -- Package_Instantiation (Node26)
2987 -- Present in packages and generic packages. When present, this field
2988 -- references an N_Package_Instantiation node associated with an
2989 -- instantiated package. In the case where the referenced node has
2990 -- been rewritten to an N_Package_Specification, the instantiation
2991 -- node is available from the Original_Node field of the package spec
2992 -- node. This is currently not guaranteed to be set in all cases, but
2993 -- when set, the field is used in Get_Package_Instantiation_Node as
2994 -- one of the means of obtaining the instantiation node. Eventually
2995 -- it should be set in all cases, including package entities associated
2996 -- with formal packages. ???
2998 -- Packed_Array_Type (Node23)
2999 -- Present in array types and subtypes, including the string literal
3000 -- subtype case, if the corresponding type is packed (either bit packed
3001 -- or packed to eliminate holes in non-contiguous enumeration type
3002 -- index types). References the type used to represent the packed array,
3003 -- which is either a modular type for short static arrays, or an
3004 -- array of System.Unsigned. Note that in some situations (internal
3005 -- types, and references to fields of variant records), it is not
3006 -- always possible to construct this type in advance of its use. If
3007 -- Packed_Array_Type is empty, then the necessary type is declared
3008 -- on the fly for each reference to the array.
3010 -- Parameter_Mode (synthesized)
3011 -- Applies to formal parameter entities. This is a synonym for Ekind,
3012 -- used when obtaining the formal kind of a formal parameter (the result
3013 -- is one of E_[In/Out/In_Out]_Paramter)
3015 -- Parent_Subtype (Node19)
3016 -- Present in E_Record_Type. Points to the subtype to use for a
3017 -- field that references the parent record.
3019 -- Primitive_Operations (Elist15)
3020 -- Present in tagged record types and subtypes and in tagged private
3021 -- types. Points to an element list of entities for primitive operations
3022 -- for the tagged type. Not present (and not set) in untagged types (it
3023 -- is an error to reference the primitive operations field of a type
3024 -- that is not tagged).
3026 -- Private_Dependents (Elist18)
3027 -- Present in private (sub)types. Records the subtypes of the
3028 -- private type, derivations from it, and records and arrays
3029 -- with components dependent on the type.
3031 -- The subtypes are traversed when installing and deinstalling
3032 -- (the full view of) a private type in order to ensure correct
3033 -- view of the subtypes.
3035 -- Used in similar fashion for incomplete types: holds list of subtypes
3036 -- of these incomplete types that have discriminant constraints. The
3037 -- full views of these subtypes are constructed when the full view of
3038 -- the incomplete type is processed.
3040 -- In addition, if the incomplete type is the designated type in an
3041 -- access definition for an access parameter, the operation may be
3042 -- a dispatching primitive operation, which is only known when the full
3043 -- declaration of the type is seen. Subprograms that have such an
3044 -- access parameter are also placed in the list of private_dependents.
3047 -- Present in components. Used for representing private declarations
3048 -- of protected objects (private formal: by analogy to Discriminal_Link).
3049 -- Empty unless the synthesized Is_Protected_Private attribute is
3050 -- true. The entity used as a formal parameter that corresponds to
3051 -- the to the private declaration in protected operations. See
3052 -- "Private data in protected objects" for details.
3054 -- Privals_Chain (Elist23)
3055 -- Present in protected operations (subprograms and entries). Links
3056 -- all occurrences of the Privals in the body of the operation, in
3057 -- order to patch their types at the end of their expansion. See
3058 -- "Private data in protected objects" for details.
3060 -- Private_View (Node22)
3061 -- For each private type, three entities are allocated, the private view,
3062 -- the full view, and the shadow entity. The shadow entity contains a
3063 -- copy of the private view and is used for restoring the proper private
3064 -- view after a region in which the full view is visible (and is copied
3065 -- into the entity normally used for the private view during this period
3066 -- of visibility). The Private_View field is self-referential when the
3067 -- private view lives in its normal entity, but in the copy that is made
3068 -- in the shadow entity, it points to the proper location in which to
3069 -- restore the private view saved in the shadow.
3071 -- Protected_Formal (Node22)
3072 -- Present in formal parameters (in, in out and out parameters). Used
3073 -- only for formals of protected operations. References corresponding
3074 -- formal parameter in the unprotected version of the operation that
3075 -- is created during expansion.
3077 -- Protected_Body_Subprogram (Node11)
3078 -- Present in protected operations. References the entity for the
3079 -- subprogram which implements the body of the operation.
3081 -- Protected_Operation (Node23)
3082 -- Present in components. Used for representing private declarations
3083 -- of protected objects. Empty unless the synthesized attribute
3084 -- Is_Protected_Private is True. This is the entity corresponding
3085 -- to the body of the protected operation currently being analyzed,
3086 -- and which will eventually use the current Prival associated with
3087 -- this component to refer to the renaming of a private object
3088 -- component. As soon as the expander generates this renaming, this
3089 -- attribute is changed to refer to the next protected subprogram.
3090 -- See "Private data in protected objects" for details.
3092 -- Reachable (Flag49)
3093 -- Present in labels. The flag is set over the range of statements in
3094 -- which a goto to that label is legal.
3096 -- Referenced (Flag156)
3097 -- Present in all entities, set if the entity is referenced, except
3098 -- for the case of an appearence of a simple variable that is not a
3099 -- renaming, as the left side of an assignment in which case the flag
3100 -- Referenced_As_LHS is set instead.
3102 -- Referenced_As_LHS (Flag36): This flag is set instead of
3103 -- Referenced if a simple variable that is not a renaming appears as
3104 -- the left side of an assignment. The reason we distinguish this kind
3105 -- of reference is that we have a separate warning for variables that
3106 -- are only assigned and never read.
3108 -- Referenced_Object (Node10)
3109 -- Present in all type entities. Set non-Empty only for type entities
3110 -- constructed for unconstrained objects, or objects that depend on
3111 -- discriminants. Points to the expression from which the actual
3112 -- subtype of the object can be evaluated.
3114 -- Register_Exception_Call (Node20)
3115 -- Present in exception entities. When an exception is declared,
3116 -- a call is expanded to Register_Exception. This field points to
3117 -- the expanded N_Procedure_Call_Statement node for this call. It
3118 -- is used for Import/Export_Exception processing to modify the
3119 -- register call to make appropriate entries in the special tables
3120 -- used for handling these pragmas at runtime.
3122 -- Related_Array_Object (Node19)
3123 -- Present in array types and subtypes. Used only for the base type
3124 -- and subtype created for an anonymous array object. Set to point
3125 -- to the entity of the corresponding array object. Currently used
3126 -- only for type-related error messages.
3128 -- Related_Instance (Node15)
3129 -- Present in the wrapper packages created for subprogram instances.
3130 -- The internal subprogram that implements the instance is inside the
3131 -- wrapper package, but for debugging purposes its external symbol
3132 -- must correspond to the name and scope of the related instance.
3134 -- Related_Interface (Node26)
3135 -- Present in components associated with secondary dispatch tables
3136 -- (dispatch table pointers and offset components). Set to point to the
3137 -- entity of the corresponding interface type.
3139 -- Renamed_Entity (Node18)
3140 -- Present in exceptions, packages, subprograms and generic units. Set
3141 -- for entities that are defined by a renaming declaration. Denotes the
3142 -- renamed entity, or transititively the ultimate renamed entity if
3143 -- there is a chain of renaming declarations. Empty if no renaming.
3145 -- Renamed_Object (Node18)
3146 -- Present in all objects (constants, variables, components, formal
3147 -- parameters, generic formal parameters, and loop parameters). Set
3148 -- non-Empty if the object was declared by a renaming declaration, in
3149 -- which case it references the tree node for the name of the renamed
3150 -- object. This is only possible for the variable and constant cases.
3151 -- For formal parameters, this field is used in the course of inline
3152 -- expansion, to map the formals of a subprogram into the corresponding
3153 -- actuals. For formals of a task entry, it denotes the local renaming
3154 -- that replaces the actual within the accept statement.
3155 -- The field is Empty otherwise.
3157 -- Renaming_Map (Uint9)
3158 -- Present in generic subprograms, generic packages, and their
3159 -- instances. Also present in the instances of the corresponding
3160 -- bodies. Denotes the renaming map (generic entities => instance
3161 -- entities) used to construct the instance by givin an index into
3162 -- the tables used to represent these maps. See Sem_Ch12 for further
3163 -- details. The maps for package instances are also used when the
3164 -- instance is the actual corresponding to a formal package.
3166 -- Requires_Overriding (Flag213)
3167 -- Present in all subprograms and entries. Set for subprograms that
3168 -- require overriding as defined by RM-2005-3.9.3(6/2). Note that this
3169 -- is True only for implicitly declare subprograms; it is not set on the
3170 -- parent type's subprogram. See also Is_Abstract_Subprogram.
3172 -- Return_Present (Flag54)
3173 -- Present in function and generic function entities. Set if the
3174 -- function contains a return statement (used for error checking).
3175 -- This flag can also be set in procedure and generic procedure
3176 -- entities (for convenience in setting it), but is only tested
3177 -- for the function case.
3179 -- Return_Applies_To (Node8)
3180 -- Present in E_Return_Statement. Points to the entity representing
3181 -- the construct to which the return statement applies, as defined in
3182 -- RM-6.5(4/2). Note that a (simple) return statement within an
3183 -- extended_return_statement applies to the extended_return_statement,
3184 -- even though it causes the whole function to return.
3186 -- Returns_By_Ref (Flag90)
3187 -- Present in function entities, to indicate that the function
3188 -- returns the result by reference, either because its return type is a
3189 -- by-reference-type or because it uses explicitly the secondary stack.
3191 -- Reverse_Bit_Order (Flag164) [base type only]
3192 -- Present in all record type entities. Set if a valid pragma an
3193 -- attribute represention clause for Bit_Order has reversed the order of
3194 -- bits from the default value. When this flag is set, a component clause
3195 -- must specify a set of bits entirely contained in a single storage unit
3196 -- (Ada 95) or a single machine scalar (see Ada 2005 AI-133), or must
3197 -- occupy in integral number of storage units.
3200 -- Present in all type and subtype entities. Contains the value of
3201 -- type'Size as defined in the RM. See also the Esize field and
3202 -- and the description on "Handling of Type'Size Values". A value
3203 -- of zero in this field for a non-discrete type means that
3204 -- the front end has not yet determined the size value. For the
3205 -- case of a discrete type, this field is always set by the front
3206 -- end and zero is a legitimate value for a type with one value.
3208 -- Root_Type (synthesized)
3209 -- Applies to all type entities. For class-wide types, return the root
3210 -- type of the class covered by the CW type, otherwise returns the
3211 -- ultimate derivation ancestor of the given type. This function
3212 -- preserves the view, i.e. the Root_Type of a partial view is the
3213 -- partial view of the ulimate ancestor, the Root_Type of a full view
3214 -- is the full view of the ultimate ancestor. Note that this function
3215 -- does not correspond exactly to the use of root type in the RM, since
3216 -- in the RM root type applies to a class of types, not to a type.
3218 -- Scalar_Range (Node20)
3219 -- Present in all scalar types (including modular types, where the
3220 -- bounds are 0 .. modulus - 1). References a node in the tree that
3221 -- contains the bounds for the range. Note that this information
3222 -- could be obtained by rummaging around the tree, but it is more
3223 -- convenient to have it immediately at hand in the entity. The
3224 -- contents of Scalar_Range can either be an N_Subtype_Indication
3225 -- node (with a constraint), or a Range node, but not a simple
3226 -- subtype reference (a subtype is converted into a range).
3228 -- Scale_Value (Uint15)
3229 -- Present in decimal fixed-point types and subtypes. Contains the scale
3230 -- for the type (i.e. the value of type'Scale = the number of decimal
3231 -- digits after the decimal point).
3234 -- Present in all entities. Points to the entity for the scope (block,
3235 -- loop, subprogram, package etc.) in which the entity is declared.
3236 -- Since this field is in the base part of the entity node, the access
3237 -- routines for this field are in Sinfo. Note that for a child package,
3238 -- the Scope will be the parent package, and for a non-child package,
3239 -- the Scope will be Standard.
3241 -- Scope_Depth (synth)
3242 -- Applies to program units, blocks, concurrent types and entries,
3243 -- and also to record types, i.e. to any entity that can appear on
3244 -- the scope stack. Yields the scope depth value, which for those
3245 -- entities other than records is simply the scope depth value,
3246 -- for record entities, it is the Scope_Depth of the record scope.
3248 -- Scope_Depth_Value (Uint22)
3249 -- Present in program units, blocks, concurrent types and entries.
3250 -- Indicates the number of scopes that statically enclose the
3251 -- declaration of the unit or type. Library units have a depth of zero.
3252 -- Note that record types can act as scopes but do NOT have this field
3253 -- set (see Scope_Depth above)
3255 -- Scope_Depth_Set (synthesized)
3256 -- Applies to a special predicate function that returns a Boolean value
3257 -- indicating whether or not the Scope_Depth field has been set. It
3258 -- is needed, since returns an invalid value in this case!
3260 -- Sec_Stack_Needed_For_Return (Flag167)
3261 -- Present in scope entities (blocks, functions, procedures, tasks,
3262 -- entries). Set to True when secondary stack is used to hold
3263 -- the returned value of a function and thus should not be
3264 -- released on scope exit.
3266 -- Shadow_Entities (List14)
3267 -- Present in package and generic package entities. Points to a list
3268 -- of entities that correspond to private types. For each private type
3269 -- a shadow entity is created that holds a copy of the private view.
3270 -- In regions of the program where the full views of these private
3271 -- entities are visible, the full view is copied into the entity that
3272 -- is normally used to hold the private view, but the shadow entity
3273 -- copy is unchanged. The shadow entities are then used to restore the
3274 -- original private views at the end of the region. This list is a
3275 -- standard format list (i.e. First (Shadow_Entities) is the first
3276 -- entry and subsequent entries are obtained using Next.
3278 -- Shared_Var_Assign_Proc (Node22)
3279 -- Present in variables. Set non-Empty only if Is_Shared_Passive is
3280 -- set, in which case this is the entity for the shared memory assign
3281 -- routine. See Exp_Smem for full details.
3283 -- Shared_Var_Read_Proc (Node15)
3284 -- Present in variables. Set non-Empty only if Is_Shared_Passive is
3285 -- set, in which case this is the entity for the shared memory read
3286 -- routine. See Exp_Smem for full details.
3288 -- Size_Check_Code (Node19)
3289 -- Present in constants and variables. Normally Empty. Set if code is
3290 -- generated to check the size of the object. This field is used to
3291 -- suppress this code if a subsequent address clause is encountered.
3293 -- Size_Clause (synthesized)
3294 -- Applies to all entities. If a size clause is present in the rep
3295 -- item chain for an entity then the attribute definition clause node
3296 -- for the size clause is returned. Otherwise Size_Clause returns Empty
3297 -- if no item is present. Usually this is only meaningful if the flag
3298 -- Has_Size_Clause is set. This is because when the representation item
3299 -- chain is copied for a derived type, it can inherit a size clause that
3300 -- is not applicable to the entity.
3302 -- Size_Depends_On_Discriminant (Flag177)
3303 -- Present in all entities for types and subtypes. Indicates that the
3304 -- size of the type depends on the value of one or more discriminants.
3305 -- Currently, this flag is only set in front end layout mode for arrays
3306 -- which have one or more bounds depending on a discriminant value.
3308 -- Size_Known_At_Compile_Time (Flag92)
3309 -- Present in all entities for types and subtypes. Indicates that the
3310 -- size of objects of the type is known at compile time. This flag is
3311 -- used to optimize some generated code sequences, and also to enable
3312 -- some error checks (e.g. disallowing component clauses on variable
3313 -- length objects. It is set conservatively (i.e. if it is True, the
3314 -- size is certainly known at compile time, if it is False, then the
3315 -- size may or may not be known at compile time, but the code will
3316 -- assume that it is not known).
3318 -- Small_Value (Ureal21)
3319 -- Present in fixed point types. Points to the universal real for the
3320 -- Small of the type, either as given in a representation clause, or
3321 -- as computed (as a power of two) by the compiler.
3323 -- Spec_Entity (Node19)
3324 -- Present in package body entities. Points to corresponding package
3325 -- spec entity. Also present in subprogram body parameters in the
3326 -- case where there is a separate spec, where this field references
3327 -- the corresponding parameter entities in the spec.
3329 -- Storage_Size_Variable (Node15) [implementation base type only]
3330 -- Present in access types and task type entities. This flag is set
3331 -- if a valid and effective pragma Storage_Size applies to the base
3332 -- type. Points to the entity for a variable that is created to
3333 -- hold the value given in a Storage_Size pragma for an access
3334 -- collection or a task type. Note that in the access type case,
3335 -- this field is present only in the root type (since derived types
3336 -- share the same storage pool).
3338 -- Static_Elaboration_Desired (Flag77)
3339 -- Present in library-level packages. Set by the pragma of the same
3340 -- name, to indicate that static initialization must be attempted for
3341 -- all types declared in the package, and that a warning must be emitted
3342 -- for those types to which static initialization is not available.
3344 -- Static_Initialization (Node26)
3345 -- Present in initialization procedures for types whose objects can be
3346 -- initialized statically. The value of this attribute is a positional
3347 -- aggregate whose components are compile-time static values. Used
3348 -- when available in object declarations to eliminate the call to the
3349 -- initialization procedure, and to minimize elaboration code.
3351 -- Stored_Constraint (Elist23)
3352 -- Present in entities that can have discriminants (concurrent types
3353 -- subtypes, record types and subtypes, private types and subtypes,
3354 -- limited private types and subtypes and incomplete types). Points
3355 -- to an element list containing the expressions for each of the
3356 -- stored discriminants for the record (sub)type.
3358 -- Strict_Alignment (Flag145) [implementation base type only]
3359 -- Present in all type entities. Indicates that some containing part
3360 -- is either aliased or tagged. This prohibits packing the object
3361 -- tighter than its natural size and alignment.
3363 -- String_Literal_Length (Uint16)
3364 -- Present in string literal subtypes (which are created to correspond
3365 -- to string literals in the program). Contains the length of the string
3368 -- String_Literal_Low_Bound (Node15)
3369 -- Present in string literal subtypes (which are created to correspond
3370 -- to string literals in the program). Contains an expression whose
3371 -- value represents the low bound of the literal. This is a copy of
3372 -- the low bound of the applicable index constraint if there is one,
3373 -- or a copy of the low bound of the index base type if not.
3375 -- Suppress_Elaboration_Warnings (Flag148)
3376 -- Present in all entities, relevant only for subprogram entities and
3377 -- for variables. If this flag is set then Sem_Elab will not generate
3378 -- elaboration warnings for the subprogram or variable. Suppression of
3379 -- such warnings is automatic for subprograms for which elaboration
3380 -- checks are suppressed (without the need to set this flag), but the
3381 -- flag is also set for various internal entities (such as init procs)
3382 -- which are known not to generate any possible access before
3383 -- elaboration, and it is set on variables when a warning is given to
3384 -- avoid multiple elaboration warnings for the same variable.
3386 -- Suppress_Init_Proc (Flag105) [base type only]
3387 -- Present in all type entities. Set to suppress the generation of
3388 -- initialization procedures where they are known to be not needed.
3389 -- For example, the enumeration image table entity uses this flag.
3391 -- Suppress_Style_Checks (Flag165)
3392 -- Present in all entities. Suppresses any style checks specifically
3393 -- associated with the given entity if set.
3395 -- Suppress_Value_Tracking_On_Call (Flag217)
3396 -- Present in all entities. Set in a scope entity if value tracking is to
3397 -- be suppressed on any call within the scope. Used when an access to a
3398 -- local subprogram is computed, to deal with the possibility that this
3399 -- value may be passed around, and if used, may clobber a local variable.
3401 -- Task_Body_Procedure (Node25)
3402 -- Present in task types and subtypes. Points to the entity for
3403 -- the task body procedure (as further described in Exp_Ch9, task
3404 -- bodies are expanded into procedures). A convenient function to
3405 -- retrieve this field is Sem_Util.Get_Task_Body_Procedure.
3406 -- The last sentence is odd ??? Why not have Task_Body_Procedure
3407 -- go to the Underlying_Type of the Root_Type???
3409 -- Treat_As_Volatile (Flag41)
3410 -- Present in all type entities, and also in constants, components and
3411 -- variables. Set if this entity is to be treated as volatile for code
3412 -- generation purposes. Always set if Is_Volatile is set, but can also
3413 -- be set as a result of situations (such as address overlays) where
3414 -- the front end wishes to force volatile handling to inhibit aliasing
3415 -- optimization which might be legally ok, but is undesirable. Note
3416 -- that the back end always tests this flag rather than Is_Volatile.
3417 -- The front end tests Is_Volatile if it is concerned with legality
3418 -- checks associated with declared volatile variables, but if the test
3419 -- is for the purposes of suppressing optimizations, then the front
3420 -- end should test Treat_As_Volatile rather than Is_Volatile.
3422 -- Type_High_Bound (synthesized)
3423 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
3424 -- the high bound of a scalar type. The returned value is literal for a
3425 -- base type, but may be an expression in the case of scalar type with
3426 -- dynamic bounds. Note that in the case of a fixed point type, the high
3427 -- bound is in units of small, and is an integer.
3429 -- Type_Low_Bound (synthesized)
3430 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
3431 -- the low bound of a scalar type. The returned value is literal for a
3432 -- base type, but may be an expression in the case of scalar type with
3433 -- dynamic bounds. Note that in the case of a fixed point type, the low
3434 -- bound is in units of small, and is an integer.
3436 -- Underlying_Full_View (Node19)
3437 -- Present in private subtypes that are the completion of other private
3438 -- types, or in private types that are derived from private subtypes. If
3439 -- the full view of a private type T is derived from another private type
3440 -- with discriminants Td, the full view of T is also private, and there
3441 -- is no way to attach to it a further full view that would convey the
3442 -- structure of T to the back end. The Underlying_Full_ View is an
3443 -- attribute of the full view that is a subtype of Td with the same
3444 -- constraint as the declaration for T. The declaration for this subtype
3445 -- is built at the point of the declaration of T, either as completion,
3446 -- or as a subtype declaration where the base type is private and has a
3447 -- private completion. If Td is already constrained, then its full view
3448 -- can serve directly as the full view of T.
3450 -- Underlying_Type (synthesized)
3451 -- Applies to all entities. This is the identity function except in the
3452 -- case where it is applied to an incomplete or private type, in which
3453 -- case it is the underlying type of the type declared by the completion,
3454 -- or Empty if the completion has not yet been encountered and analyzed.
3456 -- Note: the reason this attribute applies to all entities, and not just
3457 -- types, is to legitimize code where Underlying_Type is applied to an
3458 -- entity which may or may not be a type, with the intent that if it is a
3459 -- type, its underlying type is taken.
3461 -- Universal_Aliasing (Flag216) [base type only]
3462 -- Present in all type entities. Set to direct the back-end to avoid
3463 -- any optimizations based on type-based alias analysis for this type.
3464 -- Indicates that objects of this type can alias objects of any other
3465 -- types, which guarantees that any objects can be referenced through
3466 -- access types designating this type safely, whatever the actual type
3467 -- of these objects. In other words, the effect is as though access
3468 -- types designating this type were subject to No_Strict_Aliasing.
3470 -- Unset_Reference (Node16)
3471 -- Present in variables and out parameters. This is normally Empty. It
3472 -- is set to point to an identifier that represents a reference to the
3473 -- entity before any value has been set. Only the first such reference
3474 -- is identified. This field is used to generate a warning message if
3475 -- necessary (see Sem_Warn.Check_Unset_Reference).
3477 -- Uses_Sec_Stack (Flag95)
3478 -- Present in scope entities (blocks,functions, procedures, tasks,
3479 -- entries). Set to True when secondary stack is used in this scope and
3480 -- must be released on exit unless Sec_Stack_Needed_For_Return is set.
3482 -- Vax_Float (Flag151) [base type only]
3483 -- Present in all type entities. Set only on the base type of float
3484 -- types with Vax format. The particular format is determined by the
3485 -- Digits_Value value which is 6,9,15 for F_Float, D_Float, G_Float.
3487 -- Warnings_Off (Flag96)
3488 -- Present in all entities. Set if a pragma Warnings (Off, entity-name)
3489 -- is used to suppress warnings for a given entity. It is also used by
3490 -- the compiler in some situations to kill spurious warnings.
3492 -- Was_Hidden (Flag196)
3493 -- Present in all entities. Used to save the value of the Is_Hidden
3494 -- attribute when the limited-view is installed (Ada 2005: AI-217).
3496 -- Wrapped_Entity (Node27)
3497 -- Present in an E_Procedure classified as an Is_Primitive_Wrapper. Set
3498 -- to the entity that is being wrapped.
3504 -- The following five entity kinds are introduced by the corresponding
3505 -- type definitions:
3508 -- E_General_Access_Type,
3509 -- E_Anonymous_Access_Subprogram_Type,
3510 -- E_Anonymous_Access_Protected_Subprogram_Type
3511 -- E_Anonymous_Access_Type.
3513 -- In addition, we define the kind E_Allocator_Type to label
3514 -- allocators. This is because special resolution rules apply to this
3515 -- construct. Eventually the constructs are labeled with the access
3516 -- type imposed by the context. Gigi should never see the type
3519 -- Similarly, the type E_Access_Attribute_Type is used as the initial
3520 -- kind associated with an access attribute. After resolution a specific
3521 -- access type will be established as determined by the context.
3523 -- Finally, the type Any_Access is used to label -null- during type
3524 -- resolution. Any_Access is also replaced by the context type after

3528 -- Classification of Entities --
3529 --------------------------------
3531 -- The classification of program entities which follows is a refinement of
3532 -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
3533 -- different type classes. Ada 95 entities include class wide types,
3534 -- protected types, subprogram types, generalized access types, generic
3535 -- formal derived types and generic formal packages.
3537 -- The order chosen for these kinds allows us to classify related entities
3538 -- so that they are contiguous. As a result, they do not appear in the
3539 -- exact same order as their order of first appearance in the LRM (For
3540 -- example, private types are listed before packages). The contiguity
3541 -- allows us to define useful subtypes (see below) such as type entities,
3542 -- overloaded entities, etc.
3544 -- Each entity (explicitly or implicitly declared) has a kind, which is
3545 -- a value of the following type:
3547 type Entity_Kind is (
3550 -- The initial Ekind value for a newly created entity. Also used as
3551 -- the Ekind for Standard_Void_Type, a type entity in Standard used
3552 -- as a dummy type for the return type of a procedure (the reason we
3553 -- create this type is to share the circuits for performing overload
3554 -- resolution on calls).

3565 -- protected objects.

3929 -- A task body. This entity serves almost no function, since all
3930 -- semantic analysis uses the protected entity (E_Task_Type).
3933 -- A subprogram body. Used when a subprogram has a separate declaration
3934 -- to represent the entity for the body. This entity serves almost no

5225 -- Since E_Void is the initial Ekind value of an entity when it is first
5226 -- created, one might expect that no attributes would be defined on such
5227 -- an entity until its Ekind field is set. However, in practice, there
5228 -- are many instances in which fields of an E_Void entity are set in the
5229 -- code prior to setting the Ekind field. This is not well documented or
5230 -- well controlled, and needs cleaning up later. Meanwhile, the access
5231 -- procedures in the body of Einfo permit many, but not all, attributes
5232 -- to be applied to an E_Void entity, precisely so that this kind of
5233 -- pre-setting of attributes works. This is really a hole in the dynamic
5234 -- type checking, since there is no assurance that the eventual Ekind
5235 -- value will be appropriate for the attributes set, and the consequence
5236 -- is that the dynamic type checking in the Einfo body is unnecessarily
5237 -- weak. To be looked at systematically some time ???

5285 -- Handling of Check Suppression --
5286 -----------------------------------
5288 -- There are three ways that checks can be suppressed:
5290 -- 1. At the command line level
5291 -- 2. At the scope level.
5292 -- 3. At the entity level.
5294 -- See spec of Sem in sem.ads for details of the data structures used
5295 -- to keep track of these various methods for suppressing checks.
5297 -------------------------------
5298 -- Handling of Discriminants --
5299 -------------------------------
5301 -- During semantic processing, discriminants are separate entities which
5302 -- reflect the semantic properties and allowed usage of discriminants in
5305 -- In the case of discriminants used as bounds, the references are handled
5306 -- directly, since special processing is needed in any case. However, there
5307 -- are two circumstances in which discriminants are referenced in a quite
5308 -- general manner, like any other variables:
5310 -- In initialization expressions for records. Note that the expressions
5311 -- used in Priority, Storage_Size, and Task_Info pragmas are effectively
5312 -- in this category, since these pragmas are converted to initialized
5313 -- record fields in the Corresponding_Record_Type.
5315 -- In task and protected bodies, where the discriminant values may be
5316 -- referenced freely within these bodies. Discriminants can also appear
5317 -- in bounds of entry families and in defaults of operations.
5319 -- In both these cases, the discriminants must be treated essentially as
5320 -- objects. The following approach is used to simplify and minimize the
5321 -- special processing that is required.
5323 -- When a record type with discriminants is processed, the semantic
5324 -- processing creates the entities for the discriminants. It also creates
5325 -- an additional set of entities, called discriminals, one for each of
5326 -- the discriminants, and the Discriminal field of the discriminant entity
5327 -- points to this additional entity, which is initially created as an
5328 -- uninitialized (E_Void) entity.
5330 -- During expansion of expressions, any discriminant reference is replaced
5331 -- by a reference to the corresponding discriminal. When the initialization
5332 -- procedure for the record is created (there will always be one, since
5333 -- discriminants are present, see Exp_Ch3 for further details), the
5334 -- discriminals are used as the entities for the formal parameters of
5335 -- this initialization procedure. The references to these discriminants
5336 -- have already been replaced by references to these discriminals, which
5337 -- are now the formal parameters corresponding to the required objects.
5339 -- In the case of a task or protected body, the semantics similarly
5340 -- creates a set of discriminals for the discriminants of the task or
5341 -- protected type. When the procedure is created for the task body,
5342 -- the parameter passed in is a reference to the task value type, which
5343 -- contains the required discriminant values. The expander creates a
5344 -- set of declarations of the form:
5346 -- discriminal : constant dtype renames _Task.discriminant;
5348 -- where discriminal is the discriminal entity referenced by the task
5349 -- discriminant, and _Task is the task value passed in as the parameter.
5350 -- Again, any references to discriminants in the task body have been
5351 -- replaced by the discriminal reference, which is now an object that
5352 -- contains the required value.
5354 -- This approach for tasks means that two sets of discriminals are needed
5355 -- for a task type, one for the initialization procedure, and one for the
5356 -- task body. This works out nicely, since the semantics allocates one set
5357 -- for the task itself, and one set for the corresponding record.
5359 -- The one bit of trickiness arises in making sure that the right set of
5360 -- discriminals is used at the right time. First the task definition is
5361 -- processed. Any references to discriminants here are replaced by the
5362 -- the corresponding *task* discriminals (the record type doesn't even
5363 -- exist yet, since it is constructed as part of the expansion of the
5364 -- task declaration, which happens after the semantic processing of the
5365 -- task definition). The discriminants to be used for the corresponding
5366 -- record are created at the same time as the other discriminals, and
5367 -- held in the CR_Discriminant field of the discriminant. A use of the
5368 -- discriminant in a bound for an entry family is replaced with the CR_
5369 -- discriminant because it controls the bound of the entry queue array
5370 -- which is a component of the corresponding record.
5372 -- Just before the record initialization routine is constructed, the
5373 -- expander exchanges the task and record discriminals. This has two
5374 -- effects. First the generation of the record initialization routine
5375 -- uses the discriminals that are now on the record, which is the set
5376 -- that used to be on the task, which is what we want.
5378 -- Second, a new set of (so far unused) discriminals is now on the task
5379 -- discriminants, and it is this set that will be used for expanding the
5380 -- task body, and also for the discriminal declarations at the start of
5383 ---------------------------------------
5384 -- Private data in protected objects --
5385 ---------------------------------------
5387 -- Private object declarations in protected types pose problems
5388 -- similar to those of discriminants. They are expanded to components
5389 -- of a record which is passed as the parameter "_object" to expanded
5390 -- forms of all protected operations. As with discriminants, timing
5391 -- of this expansion is a problem. The sequence of statements for a
5392 -- protected operation is expanded before the operation itself, so the
5393 -- formal parameter for the record object containing the private data
5394 -- does not exist when the references to that data are expanded.
5396 -- For this reason, private data is handled in the same way as
5397 -- discriminants, expanding references to private data in protected
5398 -- operations (which appear as components) to placeholders which will
5399 -- eventually become renamings of the private selected components
5400 -- of the "_object" formal parameter. These placeholders are called
5401 -- "privals", by analogy to the "discriminals" used to implement
5402 -- discriminants. They are attached to the component declaration nodes
5403 -- representing the private object declarations of the protected type.
5405 -- As with discriminals, each protected subprogram needs a unique set
5406 -- of privals, since they must refer to renamings of components of a
5407 -- formal parameter of that operation. Entry bodies need another set,
5408 -- which they all share and which is associated with renamings in the
5409 -- Service_Entries procedure for the protected type (this is not yet
5410 -- implemented???). This means that we must associate a new set of
5411 -- privals (and discriminals) with the private declarations after
5412 -- the body of a protected subprogram is processed.
5414 -- The last complication is the presence of discriminants and discriminated
5415 -- components. In the corresponding record, the components are constrained
5416 -- by the discriminants of the record, but within each protected operation
5417 -- they are constrained by the discriminants of the actual. The actual
5418 -- subtypes of those components are constructed as for other unconstrained
5419 -- formals, but the privals are created before the formal object is added
5420 -- to the parameter list of the protected operation, so they carry the
5421 -- nominal subtype of the original component. After the protected operation
5422 -- is actually created (in the expansion of the protected body) we must
5423 -- patch the types of each prival occurrence with the proper actual subtype
5424 -- which is by now set. The Privals_Chain is used for this patching.
5430 -- The following type synonyms are used to tidy up the function and
5431 -- procedure declarations that follow, and also to make it possible
5432 -- to meet the requirement for the XEINFO utility that all function
5433 -- specs must fit on a single source line.
