39 -- This package defines the annotations to the abstract syntax tree that
40 -- are needed to support semantic processing of an Ada compilation.
42 -- Note that after editing this spec and the corresponding body it is
43 -- required to run ceinfo to check the consistentcy of spec and body.
44 -- See ceinfo.adb for more information about the checks made.
46 -- These annotations are for the most part attributes of declared entities,
47 -- and they correspond to conventional symbol table information. Other
48 -- attributes include sets of meanings for overloaded names, possible
49 -- types for overloaded expressions, flags to indicate deferred constants,
50 -- incomplete types, etc. These attributes are stored in available fields
51 -- in tree nodes (i.e. fields not used by the parser, as defined by the
52 -- Sinfo package specification), and accessed by means of a set of
53 -- subprograms which define an abstract interface.
55 -- There are two kinds of semantic information
57 -- First, the tree nodes with the following Nkind values:
59 -- N_Defining_Identifier
60 -- N_Defining_Character_Literal
61 -- N_Defining_Operator_Symbol
63 -- are called Entities, and constitute the information that would often
64 -- be stored separately in a symbol table. These nodes are all extended
65 -- to provide extra space, and contain fields which depend on the entity
66 -- kind, as defined by the contents of the Ekind field. The use of the
67 -- Ekind field, and the associated fields in the entity, are defined
68 -- in this package, as are the access functions to these fields.
70 -- Second, in some cases semantic information is stored directly in other
71 -- kinds of nodes, e.g. the Etype field, used to indicate the type of an
72 -- expression. The access functions to these fields are defined in the
73 -- Sinfo package, but their full documentation is to be found in
74 -- the Einfo package specification.
76 -- Declaration processing places information in the nodes of their defining
77 -- identifiers. Name resolution places in all other occurrences of an
78 -- identifier a pointer to the corresponding defining occurrence.

81 -- The XEINFO Utility Program --
82 --------------------------------
84 -- XEINFO is a utility program which automatically produces a C header file,
85 -- einfo.h from the spec and body of package Einfo. It reads the input
86 -- files einfo.ads and einfo.adb and produces the output file einfo.h.
87 -- XEINFO is run automatically by the build scripts when you do a full
90 -- In order for this utility program to operate correctly, the form of the
91 -- einfo.ads and einfo.adb files must meet certain requirements and be laid
92 -- out in a specific manner.
94 -- The general form of einfo.ads is as follows:
96 -- type declaration for type Entity_Kind
97 -- subtype declarations declaring subranges of Entity_Kind
98 -- subtype declarations declaring synonyms for some standard types
99 -- function specs for attributes
101 -- pragma Inline declarations
103 -- This order must be observed. There are no restrictions on the procedures,
104 -- since the C header file only includes functions (Gigi is not allowed to
105 -- modify the generated tree). However, functions are required to have headers
106 -- that fit on a single line.
108 -- XEINFO reads and processes the function specs and the pragma Inlines. For
109 -- functions that are declared as inlined, XEINFO reads the corresponding body
110 -- from einfo.adb, and processes it into C code. This results in some strict
111 -- restrictions on which functions can be inlined:
113 -- The function spec must be on a single line
115 -- There can only be a single statement, contained on a single line,
116 -- not counting any pragma Assert statements.
118 -- This single statement must either be a function call with simple,
119 -- single token arguments, or it must be a membership test of the form
120 -- a in b, where a and b are single tokens.
122 -- For functions that are not inlined, there is no restriction on the body,
123 -- and XEINFO generates a direct reference in the C header file which allows
124 -- the C code in Gigi to directly call the corresponding Ada body.
126 ----------------------------------
127 -- Handling of Type'Size Values --
128 ----------------------------------
130 -- The Ada 95 RM contains some rather peculiar (to us!) rules on the value
131 -- of type'Size (see RM 13.3(55)). We have found that attempting to use
132 -- these RM Size values generally, and in particular for determining the
133 -- default size of objects, creates chaos, and major incompatibilities in
136 -- We proceed as follows, for discrete and fixed-point subtypes, we have
137 -- two separate sizes for each subtype:
139 -- The Object_Size, which is used for determining the default size of
140 -- objects and components. This size value can be referred to using the
141 -- Object_Size attribute. The phrase "is used" here means that it is
142 -- the basis of the determination of the size. The backend is free to
143 -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
144 -- character might be stored in 32 bits on a machine with no efficient
145 -- byte access instructions such as the Alpha.
147 -- The default rules for the value of Object_Size for fixed-point and
148 -- discrete types are as follows:
150 -- The Object_Size for base subtypes reflect the natural hardware
151 -- size in bits (see Ttypes and Cstand for integer types). For
152 -- enumeration and fixed-point base subtypes have 8. 16. 32 or 64
153 -- bits for this size, depending on the range of values to be stored.
155 -- The Object_Size of a subtype is the same as the Object_Size of
156 -- the subtype from which it is obtained.
158 -- The Object_Size of a derived base type is copied from the parent
159 -- base type, and the Object_Size of a derived first subtype is copied
160 -- from the parent first subtype.
162 -- The Value_Size which is the number of bits required to store a value
163 -- of the type. This size can be referred to using the Value_Size
164 -- attribute. This value is used to determine how tightly to pack
165 -- records or arrays with components of this type, and also affects
166 -- the semantics of unchecked conversion (unchecked conversions where
167 -- the Value_Size values differ generate a warning, and are potentially
168 -- target dependent).
170 -- The default rule for the value of Value_Size are as follows:
172 -- The Value_Size for a base subtype is the minimum number of bits
173 -- required to store all values of the type (including the sign bit
174 -- only if negative values are possible).
176 -- If a subtype statically matches the first subtype, then it has
177 -- by default the same Value_Size as the first subtype. This is a
178 -- consequence of RM 13.1(14) ("if two subtypes statically match,
179 -- then their subtype-specific aspects are the same".)
181 -- All other subtypes have a Value_Size corresponding to the minimum
182 -- number of bits required to store all values of the subtype. For
183 -- dynamic bounds, it is assumed that the value can range down or up
184 -- to the corresponding bound of the ancestor
186 -- The RM defined attribute Size corresponds to the Value_Size attribute
188 -- The Size attribute may be defined for a first-named subtype. This sets
189 -- the Value_Size of the first-named subtype to the given value, and the
190 -- Object_Size of this first-named subtype to the given value padded up
191 -- to an appropriate boundary. It is a consequence of the default rules
192 -- above that this Object_Size will apply to all further subtypes. On the
193 -- other hand, Value_Size is affected only for the first subtype, any
194 -- dynamic subtypes obtained from it directly, and any statically matching
195 -- subtypes. The Value_Size of any other static subtypes is not affected.
197 -- Value_Size and Object_Size may be explicitly set for any subtype using
198 -- an attribute definition clause. Note that the use of these attributes
199 -- can cause the RM 13.1(14) rule to be violated. If two access types
200 -- reference aliased objects whose subtypes have differing Object_Size
201 -- values as a result of explicit attribute definition clauses, then it
202 -- is erroneous to convert from one access subtype to the other.
204 -- At the implementation level, Esize stores the Object_Size and the
205 -- RM_Size field stores the Value_Size (and hence the value of the
206 -- Size attribute, which, as noted above, is equivalent to Value_Size).
208 -- To get a feel for the difference, consider the following examples (note
209 -- that in each case the base is short_short_integer with a size of 8):
211 -- Object_Size Value_Size
213 -- type x1 is range 0..5; 8 3
215 -- type x2 is range 0..5;
216 -- for x2'size use 12; 16 12
218 -- subtype x3 is x2 range 0 .. 3; 16 2
220 -- subtype x4 is x2'base range 0 .. 10; 8 4
222 -- subtype x5 is x2 range 0 .. dynamic; 16 (7)
224 -- subtype x6 is x2'base range 0 .. dynamic; 8 (7)
226 -- Note: the entries marked (7) are not actually specified by the Ada 95 RM,
227 -- but it seems in the spirit of the RM rules to allocate the minimum number
228 -- of bits known to be large enough to hold the given range of values.
230 -- So far, so good, but GNAT has to obey the RM rules, so the question is
231 -- under what conditions must the RM Size be used. The following is a list
232 -- of the occasions on which the RM Size must be used:
234 -- Component size for packed arrays or records
235 -- Value of the attribute Size for a type
236 -- Warning about sizes not matching for unchecked conversion
238 -- The RM_Size field keeps track of the RM Size as needed in these
241 -- For elementary types other than discrete and fixed-point types, the
242 -- Object_Size and Value_Size are the same (and equivalent to the RM
243 -- attribute Size). Only Size may be specified for such types.
245 -- For composite types, Object_Size and Value_Size are computed from their
246 -- respective value for the type of each element as well as the layout.
248 -- All size attributes are stored as Uint values. Negative values are used to
249 -- reference GCC expressions for the case of non-static sizes, as explained
252 --------------------------------------
253 -- Delayed Freezing and Elaboration --
254 --------------------------------------
256 -- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
257 -- freeze node, which appears later in the expanded tree.
259 -- a) The flag is used by the front-end to trigger expansion actions which
260 -- include the generation of that freeze node. Typically this happens at the
261 -- end of the current compilation unit, or before the first subprogram body is
262 -- encountered in the current unit. See files freeze and exp_ch13 for details
263 -- on the actions triggered by a freeze node, which include the construction
264 -- of initialization procedures and dispatch tables.
266 -- b) The presence of a freeze node on an entity is used by the backend to
267 -- defer elaboration of the entity until its freeze node is seen. In the
268 -- absence of an explicit freeze node, an entity is frozen (and elaborated)
269 -- at the point of declaration.
271 -- For object declarations, the flag is set when an address clause for the
272 -- object is encountered. Legality checks on the address expression only take
273 -- place at the freeze point of the object.
275 -- Most types have an explicit freeze node, because they cannot be elaborated
276 -- until all representation and operational items that apply to them have been
277 -- analyzed. Private types and incomplete types have the flag set as well, as
278 -- do task and protected types.
280 -- Implicit base types created for type derivations, as well as classwide
281 -- types created for all tagged types, have the flag set.
283 -- If a subprogram has an access parameter whose designated type is incomplete
284 -- the subprogram has the flag set.
286 -----------------------
287 -- Entity Attributes --
288 -----------------------
290 -- This section contains a complete list of the attributes that are defined
291 -- on entities. Some attributes apply to all entities, others only to certain
292 -- kinds of entities. In the latter case the attribute should only be set or
293 -- accessed if the Ekind field indicates an appropriate entity.
295 -- There are two kinds of attributes that apply to entities, stored and
296 -- synthesized. Stored attributes correspond to a field or flag in the entity
297 -- itself. Such attributes are identified in the table below by giving the
298 -- field or flag in the attribute that is used to hold the attribute value.
299 -- Synthesized attributes are not stored directly, but are rather computed as
300 -- needed from other attributes, or from information in the tree. These are
301 -- marked "synthesized" in the table below. The stored attributes have both
302 -- access functions and set procedures to set the corresponding values, while
303 -- synthesized attributes have only access functions.
305 -- Note: in the case of Node, Uint, or Elist fields, there are cases where
306 -- the same physical field is used for different purposes in different
307 -- entities, so these access functions should only be referenced for the
308 -- class of entities in which they are defined as being present. Flags are
309 -- not overlapped in this way, but nevertheless as a matter of style and
310 -- abstraction (which may or may not be checked by assertions in the body),
311 -- this restriction should be observed for flag fields as well.
313 -- Note: certain of the attributes on types apply only to base types, and
314 -- are so noted by the notation [base type only]. These are cases where the
315 -- attribute of any subtype is the same as the attribute of the base type.
316 -- The attribute can be referenced on a subtype (and automatically retrieves
317 -- the value from the base type). However, it is an error to try to set the
318 -- attribute on other than the base type, and if assertions are enabled,
319 -- an attempt to set the attribute on a subtype will raise an assert error.
321 -- Other attributes are noted as applying to the [implementation base type
322 -- only]. These are representation attributes which must always apply to a
323 -- full non-private type, and where the attributes are always on the full
324 -- type. The attribute can be referenced on a subtype (and automatically
325 -- retries the value from the implementation base type). However, it is an
326 -- error to try to set the attribute on other than the implementation base
327 -- type, and if assertions are enabled, an attempt to set the attribute on a
328 -- subtype will raise an assert error.
330 -- Abstract_States (Elist25)
331 -- Defined for E_Package entities. Contains a list of all the abstract
332 -- states declared by the related package.
334 -- Accept_Address (Elist21)
335 -- Defined in entries. If an accept has a statement sequence, then an
336 -- address variable is created, which is used to hold the address of the
337 -- parameters, as passed by the runtime. Accept_Address holds an element
338 -- list which represents a stack of entities for these address variables.
339 -- The current entry is the top of the stack, which is the last element
340 -- on the list. A stack is required to handle the case of nested select
341 -- statements referencing the same entry.
343 -- Access_Disp_Table (Elist16) [implementation base type only]
344 -- Defined in E_Record_Type and E_Record_Subtype entities. Set in tagged
345 -- types to point to their dispatch tables. The first two entities are
346 -- associated with the primary dispatch table: 1) primary dispatch table
347 -- with user-defined primitives 2) primary dispatch table with predefined
348 -- primitives. For each interface type covered by the tagged type we also
349 -- have: 3) secondary dispatch table with thunks of primitives covering
350 -- user-defined interface primitives, 4) secondary dispatch table with
351 -- thunks of predefined primitives, 5) secondary dispatch table with user
352 -- defined primitives, and 6) secondary dispatch table with predefined
353 -- primitives. The last entity of this list is an access type declaration
354 -- used to expand dispatching calls through the primary dispatch table.
355 -- For a non-tagged record, contains No_Elist.
357 -- Actual_Subtype (Node17)
358 -- Defined in variables, constants, and formal parameters. This is the
359 -- subtype imposed by the value of the object, as opposed to its nominal
360 -- subtype, which is imposed by the declaration. The actual subtype
361 -- differs from the nominal one when the latter is indefinite (as in the
362 -- case of an unconstrained formal parameter, or a variable declared
363 -- with an unconstrained type and an initial value). The nominal subtype
364 -- is the Etype entry for the entity. The Actual_Subtype field is set
365 -- only if the actual subtype differs from the nominal subtype. If the
366 -- actual and nominal subtypes are the same, then the Actual_Subtype
367 -- field is Empty, and Etype indicates both types.
369 -- For objects, the Actual_Subtype is set only if this is a discriminated
370 -- type. For arrays, the bounds of the expression are obtained and the
371 -- Etype of the object is directly the constrained subtype. This is
372 -- rather irregular, and the semantic checks that depend on the nominal
373 -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
375 -- Address_Clause (synthesized)
376 -- Applies to entries, objects and subprograms. Set if an address clause
377 -- is present which references the object or subprogram and points to
378 -- the N_Attribute_Definition_Clause node. Empty if no Address clause.
379 -- The expression in the address clause is always a constant that is
380 -- defined before the entity to which the address clause applies.
381 -- Note: Gigi references this field in E_Task_Type entities???
383 -- Address_Taken (Flag104)
384 -- Defined in all entities. Set if the Address or Unrestricted_Access
385 -- attribute is applied directly to the entity, i.e. the entity is the
386 -- entity of the prefix of the attribute reference. Also set if the
387 -- entity is the second argument of an Asm_Input or Asm_Output attribute,
388 -- as the construct may entail taking its address. Used by Gigi to make
389 -- sure that the address can be meaningfully taken, and also in the case
390 -- of subprograms to control output of certain warnings.
392 -- Aft_Value (synthesized)
393 -- Applies to fixed and decimal types. Computes a universal integer
394 -- that holds value of the Aft attribute for the type.
397 -- Defined in overloadable entities (literals, subprograms, entries) and
398 -- subprograms that cover a primitive operation of an abstract interface
399 -- (that is, subprograms with the Interface_Alias attribute). In case of
400 -- overloaded entities it points to the parent subprogram of a derived
401 -- subprogram. In case of abstract interface subprograms it points to the
402 -- subprogram that covers the abstract interface primitive. Also used for
403 -- a subprogram renaming, where it points to the renamed subprogram. For
404 -- an inherited operation (of a type extension) that is overridden in a
405 -- private part, the Alias is the overriding operation. In this fashion a
406 -- call from outside the package ends up executing the new body even if
407 -- non-dispatching, and a call from inside calls the overriding operation
408 -- because it hides the implicit one. Alias is always empty for entries.
410 -- Alignment (Uint14)
411 -- Defined in entities for types and also in constants, variables
412 -- (including exceptions where it refers to the static data allocated for
413 -- an exception), loop parameters, and formal parameters. This indicates
414 -- the desired alignment for a type, or the actual alignment for an
415 -- object. A value of zero (Uint_0) indicates that the alignment has not
416 -- been set yet. The alignment can be set by an explicit alignment
417 -- clause, or set by the front-end in package Layout, or set by the
418 -- back-end as part of the back end back-annotation process. The
419 -- alignment field is also defined in E_Exception entities, but there it
420 -- is used only by the back-end for back annotation.
422 -- Alignment_Clause (synthesized)
423 -- Applies to all entities for types and objects. If an alignment
424 -- attribute definition clause is present for the entity, then this
425 -- function returns the N_Attribute_Definition clause that specifies the
426 -- alignment. If no alignment clause applies to the type, then the call
427 -- to this function returns Empty. Note that the call can return a
428 -- non-Empty value even if Has_Alignment_Clause is not set (happens with
429 -- subtype and derived type declarations). Note also that a record
430 -- definition clause with an (obsolescent) mod clause is converted
431 -- into an attribute definition clause for this purpose.
433 -- Associated_Formal_Package (Node12)
434 -- Defined in packages that are the actuals of formal_packages. Points
435 -- to the entity in the declaration for the formal package.
437 -- Associated_Node_For_Itype (Node8)
438 -- Defined in all type and subtype entities. Set non-Empty only for
439 -- Itypes. Set to point to the associated node for the Itype, i.e.
440 -- the node whose elaboration generated the Itype. This is used for
441 -- copying trees, to determine whether or not to copy an Itype, and
442 -- also for accessibility checks on anonymous access types. This
443 -- node is typically an object declaration, component declaration,
444 -- type or subtype declaration. For an access discriminant in a type
445 -- declaration, the associated_node_for_itype is the discriminant
446 -- specification. For an access parameter it is the enclosing subprogram
449 -- Itypes have no explicit declaration, and therefore are not attached to
450 -- the tree: their Parent field is always empty. The Associated_Node_For_
451 -- Itype is the only way to determine the construct that leads to the
452 -- creation of a given itype entity.
454 -- Associated_Storage_Pool (Node22) [root type only]
455 -- Defined in simple and general access type entities. References the
456 -- storage pool to be used for the corresponding collection. A value of
457 -- Empty means that the default pool is to be used. This is defined
458 -- only in the root type, since derived types must have the same pool
459 -- as the parent type.
461 -- Barrier_Function (Node12)
462 -- Defined in protected entries and entry families. This is the
463 -- subprogram declaration for the body of the function that returns
464 -- the value of the entry barrier.
466 -- Base_Type (synthesized)
467 -- Applies to all type and subtype entities. Returns the base type of a
468 -- type or subtype. The base type of a type is the type itself. The base
469 -- type of a subtype is the type that it constrains (which is always
470 -- a type entity, not some other subtype). Note that in the case of a
471 -- subtype of a private type, it is possible for the base type attribute
472 -- to return a private type, even if the subtype to which it applies is
473 -- non-private. See also Implementation_Base_Type. Note: it is allowed to
474 -- apply Base_Type to other than a type, in which case it simply returns
475 -- the entity unchanged.
477 -- Block_Node (Node11)
478 -- Defined in block entities. Points to the identifier in the
479 -- Block_Statement itself. Used when retrieving the block construct
480 -- for finalization purposes, The block entity has an implicit label
481 -- declaration in the enclosing declarative part, and has otherwise
482 -- no direct connection in the tree with the block statement. The
483 -- link is to the identifier (which is an occurrence of the entity)
484 -- and not to the block_statement itself, because the statement may
485 -- be rewritten, e.g. in the process of removing dead code.
487 -- Body_Entity (Node19)
488 -- Defined in package and generic package entities, points to the
489 -- corresponding package body entity if one is present.
491 -- Body_Needed_For_SAL (Flag40)
492 -- Defined in package and subprogram entities that are compilation
493 -- units. Indicates that the source for the body must be included
494 -- when the unit is part of a standalone library.
496 -- C_Pass_By_Copy (Flag125) [implementation base type only]
497 -- Defined in record types. Set if a pragma Convention for the record
498 -- type specifies convention C_Pass_By_Copy. This convention name is
499 -- treated as identical in all respects to convention C, except that
500 -- if it is specified for a record type, then the C_Pass_By_Copy flag
501 -- is set, and if a foreign convention subprogram has a formal of the
502 -- corresponding type, then the parameter passing mechanism will be
503 -- set to By_Copy (unless specifically overridden by an Import or
506 -- Can_Never_Be_Null (Flag38)
507 -- This flag is defined in all entities, but can only be set in an object
508 -- which can never have a null value. This is set True for constant
509 -- access values initialized to a non-null value. This is also True for
510 -- all access parameters in Ada 83 and Ada 95 modes, and for access
511 -- parameters that explicitly exclude null in Ada 2005.
513 -- This is used to avoid unnecessary resetting of the Is_Known_Non_Null
514 -- flag for such entities. In Ada 2005 mode, this is also used when
515 -- determining subtype conformance of subprogram profiles to ensure
516 -- that two formals have the same null-exclusion status.
518 -- ??? This is also set on some access types, eg the Etype of the
519 -- anonymous access type of a controlling formal.
521 -- Can_Use_Internal_Rep (Flag229) [base type only]
522 -- Defined in Access_Subprogram_Kind nodes. This flag is set by the
523 -- front end and used by the back end. False means that the back end
524 -- must represent the type in the same way as Convention-C types (and
525 -- other foreign-convention types). On many targets, this means that
526 -- the back end will use dynamically generated trampolines for nested
527 -- subprograms. True means that the back end can represent the type in
528 -- some internal way. On the aforementioned targets, this means that the
529 -- back end will not use dynamically generated trampolines. This flag
530 -- must be False if Has_Foreign_Convention is True; otherwise, the front
531 -- end is free to set the policy.
533 -- Setting this False in all cases corresponds to the traditional back
534 -- end strategy, where all access-to-subprogram types are represented the
535 -- same way, independent of the Convention. For further details, see also
536 -- Always_Compatible_Rep in Targparm.
538 -- Efficiency note: On targets that use dynamically generated
539 -- trampolines, False generally favors efficiency of top-level
540 -- subprograms, whereas True generally favors efficiency of nested
541 -- ones. On other targets, this flag has little or no effect on
542 -- efficiency. The front end should take this into account. In
543 -- particular, pragma Favor_Top_Level gives a hint that the flag
546 -- Note: We considered using Convention-C for this purpose, but we need
547 -- this separate flag, because Convention-C implies that in the case of
548 -- P'[Unrestricted_]Access, P also have convention C. Sometimes we want
549 -- to have Can_Use_Internal_Rep False for an access type, but allow P to
550 -- have convention Ada.
553 -- Defined in all entities. This field contains an entry into the names
554 -- table that has the character string of the identifier, character
555 -- literal or operator symbol. See Namet for further details. Note that
556 -- throughout the processing of the front end, this name is the simple
557 -- unqualified name. However, just before gigi is called, a call is made
558 -- to Qualify_All_Entity_Names. This causes entity names to be qualified
559 -- using the encoding described in exp_dbug.ads, and from that point on
560 -- (including post gigi steps such as cross-reference generation), the
561 -- entities will contain the encoded qualified names.
563 -- Checks_May_Be_Suppressed (Flag31)
564 -- Defined in all entities. Set if a pragma Suppress or Unsuppress
565 -- mentions the entity specifically in the second argument. If this
566 -- flag is set the Global_Entity_Suppress and Local_Entity_Suppress
567 -- tables must be consulted to determine if there actually is an active
568 -- Suppress or Unsuppress pragma that applies to the entity.
570 -- Class_Wide_Type (Node9)
571 -- Defined in all type entities. For a tagged type or subtype, returns
572 -- the corresponding implicitly declared class-wide type. For a
573 -- class-wide type, returns itself. Set to Empty for non-tagged types.
575 -- Cloned_Subtype (Node16)
576 -- Defined in E_Record_Subtype and E_Class_Wide_Subtype entities.
577 -- Each such entity can either have a Discriminant_Constraint, in
578 -- which case it represents a distinct type from the base type (and
579 -- will have a list of components and discrimants in the list headed by
580 -- First_Entity) or else no such constraint, in which case it will be a
581 -- copy of the base type.
583 -- o Each element of the list in First_Entity is copied from the base
584 -- type; in that case, this field is Empty.
586 -- o The list in First_Entity is shared with the base type; in that
587 -- case, this field points to that entity.
589 -- A record or classwide subtype may also be a copy of some other
590 -- subtype and share the entities in the First_Entity with that subtype.
591 -- In that case, this field points to that subtype.
593 -- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
594 -- this field. Note that this field ONLY appears in subtype entries, not
595 -- in type entries, it is not defined, and it is an error to reference
596 -- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
599 -- This flag appears on all nodes, including entities, and indicates
600 -- that the node was created by the scanner or parser from the original
601 -- source. Thus for entities, it indicates that the entity is defined
602 -- in the original source program.
604 -- Component_Alignment (special field) [base type only]
605 -- Defined in array and record entities. Contains a value of type
606 -- Component_Alignment_Kind indicating the alignment of components.
607 -- Set to Calign_Default normally, but can be overridden by use of
608 -- the Component_Alignment pragma. Note: this field is currently
609 -- stored in a non-standard way, see body for details.
611 -- Component_Bit_Offset (Uint11)
612 -- Defined in record components (E_Component, E_Discriminant) if a
613 -- component clause applies to the component. First bit position of
614 -- given component, computed from the first bit and position values
615 -- given in the component clause. A value of No_Uint means that the
616 -- value is not yet known. The value can be set by the appearance of
617 -- an explicit component clause in a record representation clause,
618 -- or it can be set by the front-end in package Layout, or it can be
619 -- set by the backend. By the time backend processing is completed,
620 -- this field is always set. A negative value is used to represent
621 -- a value which is not known at compile time, and must be computed
622 -- at run-time (this happens if fields of a record have variable
623 -- lengths). See package Layout for details of these values.
625 -- Note: Component_Bit_Offset is redundant with respect to the fields
626 -- Normalized_First_Bit and Normalized_Position, and could in principle
627 -- be eliminated, but it is convenient in several situations, including
628 -- use in Gigi, to have this redundant field.
630 -- Component_Clause (Node13)
631 -- Defined in record components and discriminants. If a record
632 -- representation clause is present for the corresponding record type a
633 -- that specifies a position for the component, then the Component_Clause
634 -- field of the E_Component entity points to the N_Component_Clause node.
635 -- Set to Empty if no record representation clause was present, or if
636 -- there was no specification for this component.
638 -- Component_Size (Uint22) [implementation base type only]
639 -- Defined in array types. It contains the component size value for
640 -- the array. A value of No_Uint means that the value is not yet set.
641 -- The value can be set by the use of a component size clause, or
642 -- by the front end in package Layout, or by the backend. A negative
643 -- value is used to represent a value which is not known at compile
644 -- time, and must be computed at run-time (this happens if the type
645 -- of the component has a variable length size). See package Layout
646 -- for details of these values.
648 -- Component_Type (Node20) [implementation base type only]
649 -- Defined in array types and string types. References component type.
651 -- Corresponding_Concurrent_Type (Node18)
652 -- Defined in record types that are constructed by the expander to
653 -- represent task and protected types (Is_Concurrent_Record_Type flag
654 -- set True). Points to the entity for the corresponding task type or
657 -- Corresponding_Discriminant (Node19)
658 -- Defined in discriminants of a derived type, when the discriminant is
659 -- used to constrain a discriminant of the parent type. Points to the
660 -- corresponding discriminant in the parent type. Otherwise it is Empty.
662 -- Corresponding_Equality (Node30)
663 -- Defined in function entities for implicit inequality operators.
664 -- Denotes the explicit or derived equality operation that creates
665 -- the implicit inequality. Note that this field is not present in
666 -- other function entities, only in implicit inequality routines,
667 -- where Comes_From_Source is always False.
669 -- Corresponding_Protected_Entry (Node18)
670 -- Defined in subprogram bodies. Set for subprogram bodies that implement
671 -- a protected type entry to point to the entity for the entry.
673 -- Corresponding_Record_Type (Node18)
674 -- Defined in protected and task types and subtypes. References the
675 -- entity for the corresponding record type constructed by the expander
676 -- (see Exp_Ch9). This type is used to represent values of the task type.
678 -- Corresponding_Remote_Type (Node22)
679 -- Defined in record types that describe the fat pointer structure for
680 -- Remote_Access_To_Subprogram types. References the original access
683 -- CR_Discriminant (Node23)
684 -- Defined in discriminants of concurrent types. Denotes the homologous
685 -- discriminant of the corresponding record type. The CR_Discriminant is
686 -- created at the same time as the discriminal, and used to replace
687 -- occurrences of the discriminant within the type declaration.
689 -- Current_Use_Clause (Node27)
690 -- Defined in packages and in types. For packages, denotes the use
691 -- package clause currently in scope that makes the package use_visible.
692 -- For types, it denotes the use_type clause that makes the operators of
693 -- the type visible. Used for more precise warning messages on redundant
696 -- Current_Value (Node9)
697 -- Defined in all object entities. Set in E_Variable, E_Constant, formal
698 -- parameters and E_Loop_Parameter entities if we have trackable current
699 -- values. Set non-Empty if the (constant) current value of the variable
700 -- is known, This value is valid only for references from the same
701 -- sequential scope as the entity. The sequential scope of an entity
702 -- includes the immediate scope and any contained scopes that are package
703 -- specs, package bodies, blocks (at any nesting level) or statement
704 -- sequences in IF or loop statements.
706 -- Another related use of this field is to record information about the
707 -- value obtained from an IF or WHILE statement condition. If the IF or
708 -- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ",
709 -- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a
710 -- Current_Value field, RELOP is one of the six relational operators, and
711 -- VAL is a compile-time known value then the Current_Value field of OBJ
712 -- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node
713 -- of the relevant construct, and the Condition field of this can be
714 -- consulted to give information about the value of OBJ. For more details
715 -- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition.
717 -- Debug_Info_Off (Flag166)
718 -- Defined in all entities. Set if a pragma Suppress_Debug_Info applies
719 -- to the entity, or if internal processing in the compiler determines
720 -- that suppression of debug information is desirable. Note that this
721 -- flag is only for use by the front end as part of the processing for
722 -- determining if Needs_Debug_Info should be set. The back end should
723 -- always test Needs_Debug_Info, it should never test Debug_Info_Off.
725 -- Debug_Renaming_Link (Node25)
726 -- Used to link the variable associated with a debug renaming declaration
727 -- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
728 -- details of the use of this field.
730 -- Declaration_Node (synthesized)
731 -- Applies to all entities. Returns the tree node for the construct that
732 -- declared the entity. Normally this is just the Parent of the entity.
733 -- One exception arises with child units, where the parent of the entity
734 -- is a selected component/defining program unit name. Another exception
735 -- is that if the entity is an incomplete type that has been completed or
736 -- a private type, then we obtain the declaration node denoted by the
737 -- full type, i.e. the full type declaration node. Also note that for
738 -- subprograms, this returns the {function,procedure}_specification, not
739 -- the subprogram_declaration.
741 -- Default_Aspect_Component_Value (Node19)
742 -- Defined in array types. Holds the static value specified in a
743 -- default_component_value aspect specification for the array type.
745 -- Default_Aspect_Value (Node19)
746 -- Defined in scalar types. Holds the static value specified in a
747 -- default_value aspect specification for the type.
749 -- Default_Expr_Function (Node21)
750 -- Defined in parameters. It holds the entity of the parameterless
751 -- function that is built to evaluate the default expression if it is
752 -- more complex than a simple identifier or literal. For the latter
753 -- simple cases or if there is no default value, this field is Empty.
755 -- Default_Expressions_Processed (Flag108)
756 -- A flag in subprograms (functions, operators, procedures) and in
757 -- entries and entry families used to indicate that default expressions
758 -- have been processed and to avoid multiple calls to process the
759 -- default expressions (see Freeze.Process_Default_Expressions), which
760 -- would not only waste time, but also generate false error messages.
762 -- Default_Value (Node20)
763 -- Defined in formal parameters. Points to the node representing the
764 -- expression for the default value for the parameter. Empty if the
765 -- parameter has no default value (which is always the case for OUT
766 -- and IN OUT parameters in the absence of errors).
768 -- Delay_Cleanups (Flag114)
769 -- Defined in entities that have finalization lists (subprograms
770 -- blocks, and tasks). Set if there are pending generic body
771 -- instantiations for the corresponding entity. If this flag is
772 -- set, then generation of cleanup actions for the corresponding
773 -- entity must be delayed, since the insertion of the generic body
774 -- may affect cleanup generation (see Inline for further details).
776 -- Delay_Subprogram_Descriptors (Flag50)
777 -- Defined in entities for which exception subprogram descriptors
778 -- are generated (subprograms, package declarations and package
779 -- bodies). Defined if there are pending generic body instantiations
780 -- for the corresponding entity. If this flag is set, then generation
781 -- of the subprogram descriptor for the corresponding enities must
782 -- be delayed, since the insertion of the generic body may add entries
783 -- to the list of handlers.
785 -- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
786 -- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
787 -- a block (in which case Delay_Subprogram_Descriptors is set for the
788 -- containing subprogram). In addition Delay_Subprogram_Descriptors is
789 -- set for a library level package declaration or body which contains
790 -- delayed instantiations (in this case the descriptor refers to the
791 -- enclosing elaboration procedure).
793 -- Delta_Value (Ureal18)
794 -- Defined in fixed and decimal types. Points to a universal real
795 -- that holds value of delta for the type, as given in the declaration
796 -- or as inherited by a subtype or derived type.
798 -- Dependent_Instances (Elist8)
799 -- Defined in packages that are instances. Holds list of instances
800 -- of inner generics. Used to place freeze nodes for those instances
801 -- after that of the current one, i.e. after the corresponding generic
804 -- Depends_On_Private (Flag14)
805 -- Defined in all type entities. Set if the type is private or if it
806 -- depends on a private type.
808 -- Designated_Type (synthesized)
809 -- Applies to access types. Returns the designated type. Differs
810 -- from Directly_Designated_Type in that if the access type refers
811 -- to an incomplete type, and the full type is available, then this
812 -- full type is returned instead of the incomplete type.
814 -- Digits_Value (Uint17)
815 -- Defined in floating point types and subtypes and decimal types and
816 -- subtypes. Contains the Digits value specified in the declaration.
818 -- Direct_Primitive_Operations (Elist10)
819 -- Defined in tagged types and subtypes (including synchronized types),
820 -- in tagged private types and in tagged incomplete types. Element list
821 -- of entities for primitive operations of the tagged type. Not defined
822 -- in untagged types. In order to follow the C++ ABI, entities of
823 -- primitives that come from source must be stored in this list in the
824 -- order of their occurrence in the sources. For incomplete types the
825 -- list is always empty.
827 -- Directly_Designated_Type (Node20)
828 -- Defined in access types. This field points to the type that is
829 -- directly designated by the access type. In the case of an access
830 -- type to an incomplete type, this field references the incomplete
831 -- type. Directly_Designated_Type is typically used in implementing the
832 -- static semantics of the language; in implementing dynamic semantics,
833 -- we typically want the full view of the designated type. The function
834 -- Designated_Type obtains this full type in the case of access to an
837 -- Discard_Names (Flag88)
838 -- Defined in types and exception entities. Set if pragma Discard_Names
839 -- applies to the entity. It is also set for declarative regions and
840 -- package specs for which a Discard_Names pragma with zero arguments
841 -- has been encountered. The purpose of setting this flag is to be able
842 -- to set the Discard_Names attribute on enumeration types declared
843 -- after the pragma within the same declarative region. This flag is
844 -- set to False if a Keep_Names pragma appears for an enumeration type.
846 -- Discriminal (Node17)
847 -- Defined in discriminants (Discriminant formal: GNAT's first
848 -- coinage). The entity used as a formal parameter that corresponds
849 -- to a discriminant. See section "Handling of Discriminants" for
850 -- full details of the use of discriminals.
852 -- Discriminal_Link (Node10)
853 -- Defined in E_In_Parameter or E_Constant entities. For discriminals,
854 -- points back to corresponding discriminant. For other entities, must
857 -- Discriminant_Checking_Func (Node20)
858 -- Defined in components. Points to the defining identifier of the
859 -- function built by the expander returns a Boolean indicating whether
860 -- the given record component exists for the current discriminant
863 -- Discriminant_Constraint (Elist21)
864 -- Defined in entities whose Has_Discriminants flag is set (concurrent
865 -- types, subtypes, record types and subtypes, private types and
866 -- subtypes, limited private types and subtypes and incomplete types).
867 -- It is an error to reference the Discriminant_Constraint field if
868 -- Has_Discriminants is False.
870 -- If the Is_Constrained flag is set, Discriminant_Constraint points
871 -- to an element list containing the discriminant constraints in the
872 -- same order in which the discriminants are declared.
874 -- If the Is_Constrained flag is not set but the discriminants of the
875 -- unconstrained type have default initial values then this field
876 -- points to an element list giving these default initial values in
877 -- the same order in which the discriminants are declared. Note that
878 -- in this case the entity cannot be a tagged record type, because
879 -- discriminants in this case cannot have defaults.
881 -- If the entity is a tagged record implicit type, then this field is
882 -- inherited from the first subtype (so that the itype is subtype
883 -- conformant with its first subtype, which is needed when the first
884 -- subtype overrides primitive operations inherited by the implicit
887 -- In all other cases Discriminant_Constraint contains the empty
888 -- Elist (ie it is initialized with a call to New_Elmt_List).
890 -- Discriminant_Default_Value (Node20)
891 -- Defined in discriminants. Points to the node representing the
892 -- expression for the default value of the discriminant. Set to
893 -- Empty if the discriminant has no default value.
895 -- Discriminant_Number (Uint15)
896 -- Defined in discriminants. Gives the ranking of a discriminant in
897 -- the list of discriminants of the type, i.e. a sequential integer
898 -- index starting at 1 and ranging up to number of discriminants.
900 -- Dispatch_Table_Wrappers (Elist26) [implementation base type only]
901 -- Defined in E_Record_Type and E_Record_Subtype entities. Set in library
902 -- level tagged type entities if we are generating statically allocated
903 -- dispatch tables. Points to the list of dispatch table wrappers
904 -- associated with the tagged type. For a non-tagged record, contains
907 -- DTC_Entity (Node16)
908 -- Defined in function and procedure entities. Set to Empty unless
909 -- the subprogram is dispatching in which case it references the
910 -- Dispatch Table pointer Component. For regular Ada tagged this, this
911 -- is the _Tag component. For CPP_Class types and their descendants,
912 -- this points to the component entity in the record that holds the
913 -- Vtable pointer for the Vtable containing the entry referencing the
916 -- DT_Entry_Count (Uint15)
917 -- Defined in E_Component entities. Only used for component marked
918 -- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
920 -- DT_Offset_To_Top_Func (Node25)
921 -- Defined in E_Component entities. Only used for component marked
922 -- Is_Tag. If present it stores the Offset_To_Top function used to
923 -- provide this value in tagged types whose ancestor has discriminants.
925 -- DT_Position (Uint15)
926 -- Defined in function and procedure entities which are dispatching
927 -- (should not be referenced without first checking that flag
928 -- Is_Dispatching_Operation is True). Contains the offset into
929 -- the Vtable for the entry that references the subprogram.
932 -- Defined in all entities. Contains a value of the enumeration type
933 -- Entity_Kind declared in a subsequent section in this spec.
935 -- Elaborate_Body_Desirable (Flag210)
936 -- Defined in package entities. Set if the elaboration circuitry detects
937 -- a case where there is a package body that modifies one or more visible
938 -- entities in the package spec and there is no explicit Elaborate_Body
939 -- pragma for the package. This information is passed on to the binder,
940 -- which attempts, but does not promise, to elaborate the body as close
941 -- to the spec as possible.
943 -- Elaboration_Entity (Node13)
944 -- Defined in generic and non-generic package and subprogram entities.
945 -- This is a counter associated with the unit that is initially set to
946 -- zero, is incremented when an elaboration request for the unit is
947 -- made, and is decremented when a finalization request for the unit
948 -- is made. This is used for three purposes. First, it is used to
949 -- implement access before elaboration checks (the counter must be
950 -- non-zero to call a subprogram at elaboration time). Second, it is
951 -- used to guard against repeated execution of the elaboration code.
952 -- Third, it is used to ensure that the finalization code is executed
953 -- only after all clients have requested it.
955 -- Note that we always allocate this counter, and set this field, but
956 -- we do not always actually use it. It is only used if it is needed
957 -- for access before elaboration use (see Elaboration_Entity_Required
958 -- flag) or if either the spec or the body has elaboration code. If
959 -- neither of these two conditions holds, then the entity is still
960 -- allocated (since we don't know early enough whether or not there
961 -- is elaboration code), but is simply not used for any purpose.
963 -- Elaboration_Entity_Required (Flag174)
964 -- Defined in generic and non-generic package and subprogram entities.
965 -- Set only if Elaboration_Entity is non-Empty to indicate that the
966 -- counter is required to be non-zero even if there is no other
967 -- elaboration code. This occurs when the Elaboration_Entity counter
968 -- is used for access before elaboration checks. If the counter is
969 -- only used to prevent multiple execution of the elaboration code,
970 -- then if there is no other elaboration code, obviously there is no
971 -- need to set the flag.
973 -- Enclosing_Scope (Node18)
974 -- Defined in labels. Denotes the innermost enclosing construct that
975 -- contains the label. Identical to the scope of the label, except for
976 -- labels declared in the body of an accept statement, in which case the
977 -- entry_name is the Enclosing_Scope. Used to validate goto's within
978 -- accept statements.
980 -- Entry_Accepted (Flag152)
981 -- Defined in E_Entry and E_Entry_Family entities. Set if there is
982 -- at least one accept for this entry in the task body. Used to
983 -- generate warnings for missing accepts.
985 -- Entry_Bodies_Array (Node15)
986 -- Defined in protected types for which Has_Entries is true.
987 -- This is the defining identifier for the array of entry body
988 -- action procedures and barrier functions used by the runtime to
989 -- execute the user code associated with each entry.
991 -- Entry_Cancel_Parameter (Node23)
992 -- Defined in blocks. This only applies to a block statement for
993 -- which the Is_Asynchronous_Call_Block flag is set. It
994 -- contains the defining identifier of an object that must be
995 -- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
996 -- call in the cleanup handler added to the block by
997 -- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
998 -- object for task entry calls and a Communications_Block object
999 -- in the case of protected entry calls. In both cases the objects
1000 -- are declared in outer scopes to this block.
1002 -- Entry_Component (Node11)
1003 -- Defined in formal parameters (in, in out and out parameters). Used
1004 -- only for formals of entries. References the corresponding component
1005 -- of the entry parameter record for the entry.
1007 -- Entry_Formal (Node16)
1008 -- Defined in components of the record built to correspond to entry
1009 -- parameters. This field points from the component to the formal. It
1010 -- is the back pointer corresponding to Entry_Component.
1012 -- Entry_Index_Constant (Node18)
1013 -- Defined in an entry index parameter. This is an identifier that
1014 -- eventually becomes the name of a constant representing the index
1015 -- of the entry family member whose entry body is being executed. Used
1016 -- to expand references to the entry index specification identifier.
1018 -- Entry_Index_Type (synthesized)
1019 -- Applies to an entry family. Denotes Etype of the subtype indication
1020 -- in the entry declaration. Used to resolve the index expression in an
1021 -- accept statement for a member of the family, and in the prefix of
1022 -- 'COUNT when it applies to a family member.
1024 -- Contract (Node24)
1025 -- Defined in entries, and in subprogram and generic subprogram entities.
1026 -- Points to the contract of the entity, holding both pre- and
1027 -- postconditions as well as test-cases.
1029 -- Entry_Parameters_Type (Node15)
1030 -- Defined in entries. Points to the access-to-record type that is
1031 -- constructed by the expander to hold a reference to the parameter
1032 -- values. This reference is manipulated (as an address) by the
1033 -- tasking runtime. The designated record represents a packaging
1034 -- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
1035 -- for further details). Entry_Parameters_Type is Empty if the entry
1036 -- has no parameters.
1038 -- Enumeration_Pos (Uint11)
1039 -- Defined in enumeration literals. Contains the position number
1040 -- corresponding to the value of the enumeration literal.
1042 -- Enumeration_Rep (Uint12)
1043 -- Defined in enumeration literals. Contains the representation that
1044 -- corresponds to the value of the enumeration literal. Note that
1045 -- this is normally the same as Enumeration_Pos except in the presence
1046 -- of representation clauses, where Pos will still represent the
1047 -- position of the literal within the type and Rep will have be the
1048 -- value given in the representation clause.
1050 -- Enumeration_Rep_Expr (Node22)
1051 -- Defined in enumeration literals. Points to the expression in an
1052 -- associated enumeration rep clause that provides the representation
1053 -- value for this literal. Empty if no enumeration rep clause for this
1054 -- literal (or if rep clause does not have an entry for this literal,
1055 -- an error situation). This is also used to catch duplicate entries
1056 -- for the same literal.
1058 -- Enum_Pos_To_Rep (Node23)
1059 -- Defined in enumeration types (but not enumeration subtypes). Set to
1060 -- Empty unless the enumeration type has a non-standard representation
1061 -- (i.e. at least one literal has a representation value different from
1062 -- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
1063 -- array constructed when the type is frozen that maps Pos values to
1064 -- corresponding Rep values. The index type of this array is Natural,
1065 -- and the component type is a suitable integer type that holds the
1066 -- full range of representation values.
1068 -- Equivalent_Type (Node18)
1069 -- Defined in class wide types and subtypes, access to protected
1070 -- subprogram types, and in exception types. For a classwide type, it
1071 -- is always Empty. For a class wide subtype, it points to an entity
1072 -- created by the expander which gives Gigi an easily understandable
1073 -- equivalent of the class subtype with a known size (given by an
1074 -- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
1075 -- details. For E_Exception_Type, this points to the record containing
1076 -- the data necessary to represent exceptions (for further details, see
1077 -- System.Standard_Library. For access_to_protected subprograms, it
1078 -- denotes a record that holds pointers to the operation and to the
1079 -- protected object. For remote Access_To_Subprogram types, it denotes
1080 -- the record that is the fat pointer representation of an RAST.
1083 -- Defined in all types and subtypes, and also for components, constants,
1084 -- and variables, including exceptions where it refers to the static data
1085 -- allocated for an exception. Contains the Object_Size of the type or of
1086 -- the object. A value of zero indicates that the value is not yet known.
1088 -- For the case of components where a component clause is present, the
1089 -- value is the value from the component clause, which must be non-
1090 -- negative (but may be zero, which is acceptable for the case of
1091 -- a type with only one possible value). It is also possible for Esize
1092 -- of a component to be set without a component clause defined, which
1093 -- means that the component size is specified, but not the position.
1094 -- See also RM_Size and the section on "Handling of Type'Size Values".
1095 -- During gigi processing, the value is back annotated for all zero
1096 -- values, so that after the call to gigi, the value is properly set.
1099 -- Defined in all entities. Represents the type of the entity, which
1100 -- is itself another entity. For a type entity, points to the parent
1101 -- type for a derived type, or if the type is not derived, points to
1102 -- itself. For a subtype entity, Etype points to the base type. For
1103 -- a class wide type, points to the corresponding specific type. For a
1104 -- subprogram or subprogram type, Etype has the return type of a function
1105 -- or is set to Standard_Void_Type to represent a procedure.
1107 -- Note one obscure case: for pragma Default_Storage_Pool (null), the
1108 -- Etype of the N_Null node is Empty.
1110 -- Exception_Code (Uint22)
1111 -- Defined in exception entities. Set to zero unless either an
1112 -- Import_Exception or Export_Exception pragma applies to the
1113 -- pragma and specifies a Code value. See description of these
1114 -- pragmas for details. Note that this field is relevant only if
1115 -- Is_VMS_Exception is set.
1117 -- Extra_Formal (Node15)
1118 -- Defined in formal parameters in the non-generic case. Certain
1119 -- parameters require extra implicit information to be passed (e.g. the
1120 -- flag indicating if an unconstrained variant record argument is
1121 -- constrained, and the accessibility level for access parameters. See
1122 -- description of Extra_Constrained, Extra_Accessibility fields for
1123 -- further details. Extra formal parameters are constructed to represent
1124 -- these values, and chained to the end of the list of formals using the
1125 -- Extra_Formal field (i.e. the Extra_Formal field of the last "real"
1126 -- formal points to the first extra formal, and the Extra_Formal field of
1127 -- each extra formal points to the next one, with Empty indicating the
1128 -- end of the list of extra formals.
1130 -- Extra_Formals (Node28)
1131 -- Applies to subprograms and subprogram types, and also in entries
1132 -- and entry families. Returns first extra formal of the subprogram
1133 -- or entry. Returns Empty if there are no extra formals.
1135 -- Extra_Accessibility (Node13)
1136 -- Defined in formal parameters in the non-generic case. Normally Empty,
1137 -- but if expansion is active, and a parameter is one for which a
1138 -- dynamic accessibility check is required, then an extra formal of type
1139 -- Natural is created (see description of field Extra_Formal), and the
1140 -- Extra_Accessibility field of the formal parameter points to the entity
1141 -- for this extra formal. Also defined in variables when compiling
1142 -- receiving stubs. In this case, a non Empty value means that this
1143 -- variable's accessibility depth has been transmitted by the caller and
1144 -- must be retrieved through the entity designed by this field instead of
1147 -- Extra_Accessibility_Of_Result (Node19)
1148 -- Defined in (non-generic) Function, Operator, and Subprogram_Type
1149 -- entities. Normally Empty, but if expansion is active, and a function
1150 -- is one for which "the accessibility level of the result ... determined
1151 -- by the point of call" (AI05-0234) is needed, then an extra formal of
1152 -- subtype Natural is created (see description of field Extra_Formal),
1153 -- and the Extra_Accessibility_Of_Result field of the function points to
1154 -- the entity for this extra formal.
1156 -- Extra_Constrained (Node23)
1157 -- Defined in formal parameters in the non-generic case. Normally Empty,
1158 -- but if expansion is active and a parameter is one for which a dynamic
1159 -- indication of its constrained status is required, then an extra formal
1160 -- of type Boolean is created (see description of field Extra_Formal),
1161 -- and the Extra_Constrained field of the formal parameter points to the
1162 -- entity for this extra formal. Also defined in variables when compiling
1163 -- receiving stubs. In this case, a non empty value means that this
1164 -- variable's constrained status has been transmitted by the caller and
1165 -- must be retrieved through the entity designed by this field instead of
1168 -- Finalization_Master (Node23) [root type only]
1169 -- Defined in access-to-controlled or access-to-class-wide types. The
1170 -- field contains the entity of the finalization master which handles
1171 -- dynamically allocated controlled objects referenced by the access
1172 -- type. Empty for access-to-subprogram types. Empty for access types
1173 -- whose designated type does not need finalization actions.
1175 -- Finalize_Storage_Only (Flag158) [base type only]
1176 -- Defined in all types. Set on direct controlled types to which a
1177 -- valid Finalize_Storage_Only pragma applies. This flag is also set on
1178 -- composite types when they have at least one controlled component and
1179 -- all their controlled components are Finalize_Storage_Only. It is also
1180 -- inherited by type derivation except for direct controlled types where
1181 -- the Finalize_Storage_Only pragma is required at each level of
1184 -- Finalizer (Node24)
1185 -- Applies to package declarations and bodies. Contains the entity of the
1186 -- library-level program which finalizes all package-level controlled
1189 -- First_Component (synthesized)
1190 -- Applies to record types. Returns the first component by following the
1191 -- chain of declared entities for the record until a component is found
1192 -- (one with an Ekind of E_Component). The discriminants are skipped. If
1193 -- the record is null, then Empty is returned.
1195 -- First_Component_Or_Discriminant (synthesized)
1196 -- Similar to First_Component, but discriminants are not skipped, so will
1197 -- find the first discriminant if discriminants are present.
1199 -- First_Entity (Node17)
1200 -- Defined in all entities which act as scopes to which a list of
1201 -- associated entities is attached (blocks, class subtypes and types,
1202 -- entries, functions, loops, packages, procedures, protected objects,
1203 -- record types and subtypes, private types, task types and subtypes).
1204 -- Points to a list of associated entities using the Next_Entity field
1205 -- as a chain pointer with Empty marking the end of the list.
1207 -- First_Exit_Statement (Node8)
1208 -- Defined in E_Loop entity. The exit statements for a loop are chained
1209 -- (in reverse order of appearance) using this field to point to the
1210 -- first entry in the chain (last exit statement in the loop). The
1211 -- entries are chained through the Next_Exit_Statement field of the
1212 -- N_Exit_Statement node with Empty marking the end of the list.
1214 -- First_Formal (synthesized)
1215 -- Applies to subprograms and subprogram types, and also in entries
1216 -- and entry families. Returns first formal of the subprogram or entry.
1217 -- The formals are the first entities declared in a subprogram or in
1218 -- a subprogram type (the designated type of an Access_To_Subprogram
1219 -- definition) or in an entry.
1221 -- First_Formal_With_Extras (synthesized)
1222 -- Applies to subprograms and subprogram types, and also in entries
1223 -- and entry families. Returns first formal of the subprogram or entry.
1224 -- Returns Empty if there are no formals. The list returned includes
1225 -- all the extra formals (see description of Extra_Formals field).
1227 -- First_Index (Node17)
1228 -- Defined in array types and subtypes and in string types and subtypes.
1229 -- By introducing implicit subtypes for the index constraints, we have
1230 -- the same structure for constrained and unconstrained arrays, subtype
1231 -- marks and discrete ranges are both represented by a subtype. This
1232 -- function returns the tree node corresponding to an occurrence of the
1233 -- first index (NOT the entity for the type). Subsequent indices are
1234 -- obtained using Next_Index. Note that this field is defined for the
1235 -- case of string literal subtypes, but is always Empty.
1237 -- First_Literal (Node17)
1238 -- Defined in all enumeration types, including character and boolean
1239 -- types. This field points to the first enumeration literal entity
1240 -- for the type (i.e. it is set to First (Literals (N)) where N is
1241 -- the enumeration type definition node. A special case occurs with
1242 -- standard character and wide character types, where this field is
1243 -- Empty, since there are no enumeration literal lists in these cases.
1244 -- Note that this field is set in enumeration subtypes, but it still
1245 -- points to the first literal of the base type in this case.
1247 -- First_Optional_Parameter (Node14)
1248 -- Defined in (non-generic) function and procedure entities. Set to a
1249 -- non-null value only if a pragma Import_Function, Import_Procedure
1250 -- or Import_Valued_Procedure specifies a First_Optional_Parameter
1251 -- argument, in which case this field points to the parameter entity
1252 -- corresponding to the specified parameter.
1254 -- First_Private_Entity (Node16)
1255 -- Defined in all entities containing private parts (packages, protected
1256 -- types and subtypes, task types and subtypes). The entities on the
1257 -- entity chain are in order of declaration, so the entries for private
1258 -- entities are at the end of the chain. This field points to the first
1259 -- entity for the private part. It is Empty if there are no entities
1260 -- declared in the private part or if there is no private part.
1262 -- First_Rep_Item (Node6)
1263 -- Defined in all entities. If non-empty, points to a linked list of
1264 -- representation pragmas nodes and representation clause nodes that
1265 -- apply to the entity, linked using Next_Rep_Item, with Empty marking
1266 -- the end of the list. In the case of derived types and subtypes, the
1267 -- new entity inherits the chain at the point of declaration. This means
1268 -- that it is possible to have multiple instances of the same kind of rep
1269 -- item on the chain, in which case it is the first one that applies to
1272 -- Note: pragmas that can apply to more than one overloadable entity,
1273 -- (Convention, Interface, Inline, Inline_Always, Import, Export,
1274 -- External) are never present on this chain when they apply to
1275 -- overloadable entities, since it is impossible for a given pragma
1276 -- to be on more than one chain at a time.
1278 -- For most representation items, the representation information is
1279 -- reflected in other fields and flags in the entity. For example if a
1280 -- record representation clause is present, the component entities
1281 -- reflect the specified information. However, there are some items that
1282 -- are only reflected in the chain. These include:
1284 -- Machine_Attribute pragma
1285 -- Link_Alias pragma
1286 -- Linker_Section pragma
1287 -- Linker_Constructor pragma
1288 -- Linker_Destructor pragma
1289 -- Weak_External pragma
1290 -- Thread_Local_Storage pragma
1292 -- If any of these items are present, then the flag Has_Gigi_Rep_Item is
1293 -- set, indicating that Gigi should search the chain.
1295 -- Other representation items are included in the chain so that error
1296 -- messages can easily locate the relevant nodes for posting errors.
1297 -- Note in particular that size clauses are defined only for this
1298 -- purpose, and should only be accessed if Has_Size_Clause is set.
1300 -- Float_Rep (Uint10)
1301 -- Defined in floating-point entities. Contains a value of type
1302 -- Float_Rep_Kind. Together with the Digits_Value uniquely defines
1303 -- the floating-point representation to be used.
1305 -- Freeze_Node (Node7)
1306 -- Defined in all entities. If there is an associated freeze node for the
1307 -- entity, this field references this freeze node. If no freeze node is
1308 -- associated with the entity, then this field is Empty. See package
1309 -- Freeze for further details.
1311 -- From_With_Type (Flag159)
1312 -- Defined in package and type entities. Indicates that the entity
1313 -- appears in a With_Type clause in the context of some other unit,
1314 -- either as the prefix (which must be a package), or as a type name.
1315 -- The package can only be used to retrieve such a type, and the type
1316 -- can be used only in component declarations and access definitions.
1317 -- The With_Type clause is used to construct mutually recursive
1318 -- types, i.e. record types (Java classes) that hold pointers to each
1319 -- other. If such a type is an access type, it has no explicit freeze
1320 -- node, so that the back-end does not attempt to elaborate it.
1321 -- Currently this flag is also used to implement Ada 2005 (AI-50217).
1322 -- It will be renamed to From_Limited_With after removal of the current
1323 -- GNAT with_type clause???
1325 -- Full_View (Node11)
1326 -- Defined in all type and subtype entities and in deferred constants.
1327 -- References the entity for the corresponding full type declaration.
1328 -- For all types other than private and incomplete types, this field
1329 -- always contains Empty. If an incomplete type E1 is completed by a
1330 -- private type E2 whose full type declaration entity is E3 then the
1331 -- full view of E1 is E2, and the full view of E2 is E3. See also
1334 -- Generic_Homonym (Node11)
1335 -- Defined in generic packages. The generic homonym is the entity of
1336 -- a renaming declaration inserted in every generic unit. It is used
1337 -- to resolve the name of a local entity that is given by a qualified
1338 -- name, when the generic entity itself is hidden by a local name.
1340 -- Generic_Renamings (Elist23)
1341 -- Defined in package and subprogram instances. Holds mapping that
1342 -- associates generic parameters with the corresponding instances, in
1343 -- those cases where the instance is an entity.
1345 -- Handler_Records (List10)
1346 -- Defined in subprogram and package entities. Points to a list of
1347 -- identifiers referencing the handler record entities for the
1348 -- corresponding unit.
1350 -- Has_Aliased_Components (Flag135) [implementation base type only]
1351 -- Defined in array type entities. Indicates that the component type
1352 -- of the array is aliased.
1354 -- Has_Alignment_Clause (Flag46)
1355 -- Defined in all type entities and objects. Indicates if an alignment
1356 -- clause has been given for the entity. If set, then Alignment_Clause
1357 -- returns the N_Attribute_Definition node for the alignment attribute
1358 -- definition clause. Note that it is possible for this flag to be False
1359 -- even when Alignment_Clause returns non_Empty (this happens in the case
1360 -- of derived type declarations).
1362 -- Has_All_Calls_Remote (Flag79)
1363 -- Defined in all library unit entities. Set true if the library unit
1364 -- has an All_Calls_Remote pragma. Note that such entities must also
1365 -- be RCI entities, so the flag Is_Remote_Call_Interface will always
1366 -- be set if this flag is set.
1368 -- Has_Anonymous_Master (Flag253)
1369 -- Defined in units (top-level functions and procedures, library-level
1370 -- packages). Set to True if the associated unit contains a heterogeneous
1371 -- finalization master. The master's name is of the form <unit>AM and it
1372 -- services anonymous access-to-controlled types with an undetermined
1375 -- Has_Atomic_Components (Flag86) [implementation base type only]
1376 -- Defined in all types and objects. Set only for an array type or
1377 -- an array object if a valid pragma Atomic_Components applies to the
1378 -- type or object. Note that in the case of an object, this flag is
1379 -- only set on the object if there was an explicit pragma for the
1380 -- object. In other words, the proper test for whether an object has
1381 -- atomic components is to see if either the object or its base type
1382 -- has this flag set. Note that in the case of a type, the pragma will
1383 -- be chained to the rep item chain of the first subtype in the usual
1386 -- Has_Attach_Handler (synthesized)
1387 -- Applies to record types that are constructed by the expander to
1388 -- represent protected types. Returns True if there is at least one
1389 -- Attach_Handler pragma in the corresponding specification.
1391 -- Has_Biased_Representation (Flag139)
1392 -- Defined in discrete types (where it applies to the type'size value),
1393 -- and to objects (both stand-alone and components), where it applies to
1394 -- the size of the object from a size or record component clause. In
1395 -- all cases it indicates that the size in question is smaller than
1396 -- would normally be required, but that the size requirement can be
1397 -- satisfied by using a biased representation, in which stored values
1398 -- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
1399 -- reduce the required size. For example, a type with a range of 1..2
1400 -- takes one bit, using 0 to represent 1 and 1 to represent 2.
1402 -- Note that in the object and component cases, the flag is only set if
1403 -- the type is unbiased, but the object specifies a smaller size than the
1404 -- size of the type, forcing biased representation for the object, but
1405 -- the subtype is still an unbiased type.
1407 -- Has_Completion (Flag26)
1408 -- Defined in all entities that require a completion (functions,
1409 -- procedures, private types, limited private types, incomplete types,
1410 -- constants and packages that require a body). The flag is set if the
1411 -- completion has been encountered and analyzed.
1413 -- Has_Completion_In_Body (Flag71)
1414 -- Defined in all entities for types and subtypes. Set only in "Taft
1415 -- amendment types" (incomplete types whose full declaration appears in
1416 -- the package body).
1418 -- Has_Complex_Representation (Flag140) [implementation base type only]
1419 -- Defined in all type entities. Set only for a record base type to
1420 -- which a valid pragma Complex_Representation applies.
1422 -- Has_Component_Size_Clause (Flag68) [implementation base type only]
1423 -- Defined in all type entities. Set if a component size clause is
1424 -- Defined for the given type. Note that this flag can be False even
1425 -- if Component_Size is non-zero (happens in the case of derived types).
1427 -- Has_Constrained_Partial_View (Flag187)
1428 -- Defined in private type and their completions, when the private
1429 -- type has no discriminants and the full view has discriminants with
1430 -- defaults. In Ada 2005 heap-allocated objects of such types are not
1431 -- constrained, and can change their discriminants with full assignment.
1433 -- Ada 2012 has an additional rule (3.3. (23/10.3)) concerning objects
1434 -- declared in a generic package body. Objects whose type is an untagged
1435 -- generic formal private type are considered to have a constrained
1436 -- partial view. The predicate Object_Type_Has_Constrained_Partial_View
1437 -- in sem_aux is used to test for this case.
1439 -- Has_Contiguous_Rep (Flag181)
1440 -- Defined in enumeration types. True if the type as a representation
1441 -- clause whose entries are successive integers.
1443 -- Has_Controlling_Result (Flag98)
1444 -- Defined in E_Function entities. True if the function is a primitive
1445 -- function of a tagged type which can dispatch on result.
1447 -- Has_Controlled_Component (Flag43) [base type only]
1448 -- Defined in all type and subtype entities. Set only for composite type
1449 -- entities which contain a component that either is a controlled type,
1450 -- or itself contains controlled component (i.e. either Is_Controlled or
1451 -- Has_Controlled_Component is set for at least one component).
1453 -- Has_Convention_Pragma (Flag119)
1454 -- Defined in all entities. Set true for an entity for which a valid
1455 -- Convention, Import, or Export pragma has been given. Used to prevent
1456 -- more than one such pragma appearing for a given entity (RM B.1(45)).
1458 -- Has_Delayed_Aspects (Flag200)
1459 -- Defined in all entities. Set true if the Rep_Item chain for the entity
1460 -- has one or more N_Aspect_Definition nodes chained which are not to be
1461 -- evaluated till the freeze point. The aspect definition expression
1462 -- clause has been preanalyzed to get visibility at the point of use,
1463 -- but no other action has been taken.
1465 -- Has_Delayed_Freeze (Flag18)
1466 -- Defined in all entities. Set to indicate that an explicit freeze
1467 -- node must be generated for the entity at its freezing point. See
1468 -- separate section ("Delayed Freezing and Elaboration") for details.
1470 -- Has_Default_Aspect (Flag39) [base type only]
1471 -- Defined in entities for types and subtypes, set for scalar types with
1472 -- a Default_Value aspect and array types with a Default_Component_Value
1473 -- apsect. If this flag is set, then a corresponding aspect specification
1474 -- node will be present on the rep item chain for the entity.
1476 -- Has_Discriminants (Flag5)
1477 -- Defined in all types and subtypes. For types that are allowed to have
1478 -- discriminants (record types and subtypes, task types and subtypes,
1479 -- protected types and subtypes, private types, limited private types,
1480 -- and incomplete types), indicates if the corresponding type or subtype
1481 -- has a known discriminant part. Always false for all other types.
1483 -- Has_Dispatch_Table (Flag220)
1484 -- Defined in E_Record_Types that are tagged. Set to indicate that the
1485 -- corresponding dispatch table is already built. This flag is used to
1486 -- avoid duplicate construction of library level dispatch tables (because
1487 -- the declaration of library level objects cause premature construction
1488 -- of the table); otherwise the code that builds the table is added at
1489 -- the end of the list of declarations of the package.
1491 -- Has_Dynamic_Predicate_Aspect (Flag258)
1492 -- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect
1493 -- applies to the type. Note that we can tell if a dynamic predicate is
1494 -- present by looking at Has_Predicates and Static_Predicate, but that
1495 -- could have come from a Predicate aspect or pragma, and we need to
1496 -- record the difference so that we can use the right set of check
1497 -- policies to figure out if the predicate is active.
1499 -- Has_Entries (synthesized)
1500 -- Applies to concurrent types. True if any entries are declared
1501 -- within the task or protected definition for the type.
1503 -- Has_Enumeration_Rep_Clause (Flag66)
1504 -- Defined in enumeration types. Set if an enumeration representation
1505 -- clause has been given for this enumeration type. Used to prevent more
1506 -- than one enumeration representation clause for a given type. Note
1507 -- that this does not imply a representation with holes, since the rep
1508 -- clause may merely confirm the default 0..N representation.
1510 -- Has_External_Tag_Rep_Clause (Flag110)
1511 -- Defined in tagged types. Set if an external_tag rep. clause has been
1512 -- given for this type. Use to avoid the generation of the default
1515 -- Has_Exit (Flag47)
1516 -- Defined in loop entities. Set if the loop contains an exit statement.
1518 -- Has_Foreign_Convention (synthesized)
1519 -- Applies to all entities. Determines if the Convention for the
1520 -- entity is a foreign convention (i.e. is other than Convention_Ada,
1521 -- Convention_Intrinsic, Convention_Entry or Convention_Protected).
1523 -- Has_Forward_Instantiation (Flag175)
1524 -- Defined in package entities. Set true for packages that contain
1525 -- instantiations of local generic entities, before the corresponding
1526 -- generic body has been seen. If a package has a forward instantiation,
1527 -- we cannot inline subprograms appearing in the same package because
1528 -- the placement requirements of the instance will conflict with the
1529 -- linear elaboration of front-end inlining.
1531 -- Has_Fully_Qualified_Name (Flag173)
1532 -- Defined in all entities. Set True if the name in the Chars field has
1533 -- been replaced by the fully qualified name, as used for debug output.
1534 -- See Exp_Dbug for a full description of the use of this flag and also
1535 -- the related flag Has_Qualified_Name.
1537 -- Has_Gigi_Rep_Item (Flag82)
1538 -- Defined in all entities. Set if the rep item chain (referenced by
1539 -- First_Rep_Item and linked through the Next_Rep_Item chain) contains a
1540 -- representation item that needs to be specially processed by Gigi, i.e.
1541 -- one of the following items:
1543 -- Machine_Attribute pragma
1544 -- Linker_Alias pragma
1545 -- Linker_Section pragma
1546 -- Linker_Constructor pragma
1547 -- Linker_Destructor pragma
1548 -- Weak_External pragma
1549 -- Thread_Local_Storage pragma
1551 -- If this flag is set, then Gigi should scan the rep item chain to
1552 -- process any of these items that appear. At least one such item will
1555 -- Has_Homonym (Flag56)
1556 -- Defined in all entities. Set if an entity has a homonym in the same
1557 -- scope. Used by Gigi to generate unique names for such entities.
1559 -- Has_Implicit_Dereference (Flag251)
1560 -- Defined in types and discriminants. Set if the type has an aspect
1561 -- Implicit_Dereference. Set also on the discriminant named in the aspect
1562 -- clause, to simplify type resolution.
1564 -- Has_Independent_Components (Flag34)
1565 -- Defined in objects and types. Set if the aspect Independent_Components
1566 -- applies (as set by coresponding pragma or aspect specification).
1568 -- Has_Inheritable_Invariants (Flag248)
1569 -- Defined in all type entities. Set True in private types from which one
1570 -- or more Invariant'Class aspects will be inherited if a another type is
1571 -- derived from the type (i.e. those types which have an Invariant'Class
1572 -- aspect, or which inherit one or more Invariant'Class aspects). Also
1573 -- set in the corresponding full types. Note that it might be the full
1574 -- type which has inheritable invariants, and in this case the flag will
1575 -- also be set in the private type.
1577 -- Has_Initial_Value (Flag219)
1578 -- Defined in entities for variables and out parameters. Set if there
1579 -- is an explicit initial value expression in the declaration of the
1580 -- variable. Note that this is set only if this initial value is
1581 -- explicit, it is not set for the case of implicit initialization
1582 -- of access types or controlled types. Always set to False for out
1583 -- parameters. Also defined in entities for in and in-out parameters,
1584 -- but always false in these cases.
1586 -- Has_Interrupt_Handler (synthesized)
1587 -- Applies to all protected type entities. Set if the protected type
1588 -- definition contains at least one procedure to which a pragma
1589 -- Interrupt_Handler applies.
1591 -- Has_Invariants (Flag232)
1592 -- Defined in all type entities and in subprogram entities. Set True in
1593 -- private types if an Invariant or Invariant'Class aspect applies to the
1594 -- type, or if the type inherits one or more Invariant'Class aspects.
1595 -- Also set in the corresponding full type. Note: if this flag is set
1596 -- True, then usually the Invariant_Procedure attribute is set once the
1597 -- type is frozen, however this may not be true in some error situations.
1598 -- Note that it might be the full type which has inheritable invariants,
1599 -- and then the flag will also be set in the private type.
1601 -- Has_Loop_Entry_Attributes (Flag260)
1602 -- Defined in E_Loop entities. Set when the loop is subject to at least
1603 -- one attribute 'Loop_Entry. The flag also implies that the loop has
1604 -- already been transformed. See Expand_Loop_Entry_Attribute for details.
1606 -- Has_Machine_Radix_Clause (Flag83)
1607 -- Defined in decimal types and subtypes, set if a Machine_Radix
1608 -- representation clause is present. This flag is used to detect
1609 -- the error of multiple machine radix clauses for a single type.
1611 -- Has_Master_Entity (Flag21)
1612 -- Defined in entities that can appear in the scope stack (see spec
1613 -- of Sem). It is set if a task master entity (_master) has been
1614 -- declared and initialized in the corresponding scope.
1616 -- Has_Missing_Return (Flag142)
1617 -- Defined in functions and generic functions. Set if there is one or
1618 -- more missing return statements in the function. This is used to
1619 -- control wrapping of the body in Exp_Ch6 to ensure that the program
1620 -- error exception is correctly raised in this case at runtime.
1622 -- Has_Nested_Block_With_Handler (Flag101)
1623 -- Defined in scope entities. Set if there is a nested block within the
1624 -- scope that has an exception handler and the two scopes are in the
1625 -- same procedure. This is used by the backend for controlling certain
1626 -- optimizations to ensure that they are consistent with exceptions.
1627 -- See documentation in Gigi for further details.
1629 -- Has_Non_Standard_Rep (Flag75) [implementation base type only]
1630 -- Defined in all type entities. Set when some representation clause
1631 -- or pragma causes the representation of the item to be significantly
1632 -- modified. In this category are changes of small or radix for a
1633 -- fixed-point type, change of component size for an array, and record
1634 -- or enumeration representation clauses, as well as packed pragmas.
1635 -- All other representation clauses (e.g. Size and Alignment clauses)
1636 -- are not considered to be significant since they do not affect
1637 -- stored bit patterns.
1639 -- Has_Object_Size_Clause (Flag172)
1640 -- Defined in entities for types and subtypes. Set if an Object_Size
1641 -- clause has been processed for the type Used to prevent multiple
1642 -- Object_Size clauses for a given entity.
1644 -- Has_Per_Object_Constraint (Flag154)
1645 -- Defined in E_Component entities, true if the subtype of the
1646 -- component has a per object constraint. Per object constraints result
1647 -- from the following situations:
1649 -- 1. N_Attribute_Reference - when the prefix is the enclosing type and
1650 -- the attribute is Access.
1651 -- 2. N_Discriminant_Association - when the expression uses the
1652 -- discriminant of the enclosing type.
1653 -- 3. N_Index_Or_Discriminant_Constraint - when at least one of the
1654 -- individual constraints is a per object constraint.
1655 -- 4. N_Range - when the lower or upper bound uses the discriminant of
1656 -- the enclosing type.
1657 -- 5. N_Range_Constraint - when the range expression uses the
1658 -- discriminant of the enclosing type.
1660 -- Has_Postconditions (Flag240)
1661 -- Defined in subprogram entities. Set if postconditions are active for
1662 -- the procedure, and a _postconditions procedure has been generated.
1664 -- Has_Pragma_Controlled (Flag27) [implementation base type only]
1665 -- Defined in access type entities. It is set if a pragma Controlled
1666 -- applies to the access type.
1668 -- Has_Pragma_Elaborate_Body (Flag150)
1669 -- Defined in all entities. Set in compilation unit entities if a
1670 -- pragma Elaborate_Body applies to the compilation unit.
1672 -- Has_Pragma_Inline (Flag157)
1673 -- Defined in all entities. Set for functions and procedures for which a
1674 -- pragma Inline or Inline_Always applies to the subprogram. Note that
1675 -- this flag can be set even if Is_Inlined is not set. This happens for
1676 -- pragma Inline (if Inline_Active is False). In other words, the flag
1677 -- Has_Pragma_Inline represents the formal semantic status, and is used
1678 -- for checking semantic correctness. The flag Is_Inlined indicates
1679 -- whether inlining is actually active for the entity.
1681 -- Has_Pragma_Inline_Always (Flag230)
1682 -- Defined in all entities. Set for functions and procedures for which a
1683 -- pragma Inline_Always applies. Note that if this flag is set, the flag
1684 -- Has_Pragma_Inline is also set.
1686 -- Has_Pragma_No_Inline (Flag201)
1687 -- Defined in all entities. Set for functions and procedures for which a
1688 -- pragma No_Inline applies. Note that if this flag is set, the flag
1689 -- Has_Pragma_Inline_Always cannot be set.
1691 -- Has_Pragma_Ordered (Flag198) [implementation base type only]
1692 -- Defined in entities for enumeration types. If set indicates that a
1693 -- valid pragma Ordered was given for the type. This flag is inherited
1694 -- by derived enumeration types. We don't need to distinguish the derived
1695 -- case since we allow multiple occurrences of this pragma anyway.
1697 -- Has_Pragma_Pack (Flag121) [implementation base type only]
1698 -- Defined in array and record type entities. If set, indicates that a
1699 -- valid pragma Pack was given for the type. Note that this flag is not
1700 -- inherited by derived type. See also the Is_Packed flag.
1702 -- Has_Pragma_Pure (Flag203)
1703 -- Defined in all entities. If set, indicates that a valid pragma Pure
1704 -- was given for the entity. In some cases, we need to test whether
1705 -- Is_Pure was explicitly set using this pragma.
1707 -- Has_Pragma_Preelab_Init (Flag221)
1708 -- Defined in type and subtype entities. If set indicates that a valid
1709 -- pragma Preelaborable_Initialization applies to the type.
1711 -- Has_Pragma_Pure_Function (Flag179)
1712 -- Defined in all entities. If set, indicates that a valid pragma
1713 -- Pure_Function was given for the entity. In some cases, we need to
1714 -- know that Is_Pure was explicitly set using this pragma. We also set
1715 -- this flag for some internal entities that we know should be treated
1716 -- as pure for optimization purposes.
1718 -- Has_Pragma_Thread_Local_Storage (Flag169)
1719 -- Defined in all entities. If set, indicates that a valid pragma
1720 -- Thread_Local_Storage was given for the entity.
1722 -- Has_Pragma_Unmodified (Flag233)
1723 -- Defined in all entities. Can only be set for variables (E_Variable,
1724 -- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified
1725 -- applies to the variable, indicating that no warning should be given
1726 -- if the entity is never modified. Note that clients should generally
1727 -- not test this flag directly, but instead use function Has_Unmodified.
1729 -- Has_Pragma_Unreferenced (Flag180)
1730 -- Defined in all entities. Set if a valid pragma Unreferenced applies
1731 -- to the entity, indicating that no warning should be given if the
1732 -- entity has no references, but a warning should be given if it is
1733 -- in fact referenced. For private types, this flag is set in both the
1734 -- private entity and full entity if the pragma applies to either. Note
1735 -- that clients should generally not test this flag directly, but instead
1736 -- use function Has_Unreferenced.
1738 -- Has_Pragma_Unreferenced_Objects (Flag212)
1739 -- Defined in type and subtype entities. Set if a valid pragma
1740 -- Unreferenced_Objects applies to the type, indicating that no warning
1741 -- should be given for objects of such a type for being unreferenced
1742 -- (but unlike the case with pragma Unreferenced, it is ok to reference
1743 -- such an object and no warning is generated.
1745 -- Has_Predicates (Flag250)
1746 -- Defined in type and subtype entities. Set if a pragma Predicate or
1747 -- Predicate aspect applies to the type or subtype, or if it inherits a
1748 -- Predicate aspect from its parent or progenitor types.
1750 -- Has_Primitive_Operations (Flag120) [base type only]
1751 -- Defined in all type entities. Set if at least one primitive operation
1752 -- is defined for the type.
1754 -- Has_Private_Ancestor (Flag151)
1755 -- Applies to untagged derived types and to type extensions. True when
1756 -- some ancestor is derived from a private type, making some components
1757 -- invisible and aggregates illegal. Used to check the legality of
1758 -- selected components and aggregates. The flag is set at the point of
1760 -- The legality of an aggregate of a type with a private ancestor must
1761 -- be checked because it also depends on the visibility at the point the
1762 -- aggregate is resolved. See sem_aggr.adb. This is part of AI05-0115.
1764 -- Has_Private_Declaration (Flag155)
1765 -- Defined in all entities. Returns True if it is the defining entity
1766 -- of a private type declaration or its corresponding full declaration.
1767 -- This flag is thus preserved when the full and the partial views are
1768 -- exchanged, to indicate if a full type declaration is a completion.
1769 -- Used for semantic checks in E.4(18) and elsewhere.
1771 -- Has_Qualified_Name (Flag161)
1772 -- Defined in all entities. Set True if the name in the Chars field
1773 -- has been replaced by its qualified name, as used for debug output.
1774 -- See Exp_Dbug for a full description of qualification requirements.
1775 -- For some entities, the name is the fully qualified name, but there
1776 -- are exceptions. In particular, for local variables in procedures,
1777 -- we do not include the procedure itself or higher scopes. See also
1778 -- the flag Has_Fully_Qualified_Name, which is set if the name does
1779 -- indeed include the fully qualified name.
1781 -- Has_RACW (Flag214)
1782 -- Defined in package spec entities. Set if the spec contains the
1783 -- declaration of a remote access-to-classwide type.
1785 -- Has_Record_Rep_Clause (Flag65) [implementation base type only]
1786 -- Defined in record types. Set if a record representation clause has
1787 -- been given for this record type. Used to prevent more than one such
1788 -- clause for a given record type. Note that this is initially cleared
1789 -- for a derived type, even though the representation is inherited. See
1790 -- also the flag Has_Specified_Layout.
1792 -- Has_Recursive_Call (Flag143)
1793 -- Defined in procedures. Set if a direct parameterless recursive call
1794 -- is detected while analyzing the body. Used to activate some error
1795 -- checks for infinite recursion.
1797 -- Has_Size_Clause (Flag29)
1798 -- Defined in entities for types and objects. Set if a size clause is
1799 -- Defined for the entity. Used to prevent multiple Size clauses for a
1800 -- given entity. Note that it is always initially cleared for a derived
1801 -- type, even though the Size for such a type is inherited from a Size
1802 -- clause given for the parent type.
1804 -- Has_Small_Clause (Flag67)
1805 -- Defined in ordinary fixed point types (but not subtypes). Indicates
1806 -- that a small clause has been given for the entity. Used to prevent
1807 -- multiple Small clauses for a given entity. Note that it is always
1808 -- initially cleared for a derived type, even though the Small for such
1809 -- a type is inherited from a Small clause given for the parent type.
1811 -- Has_Specified_Layout (Flag100) [implementation base type only]
1812 -- Defined in all type entities. Set for a record type or subtype if
1813 -- the record layout has been specified by a record representation
1814 -- clause. Note that this differs from the flag Has_Record_Rep_Clause
1815 -- in that it is inherited by a derived type. Has_Record_Rep_Clause is
1816 -- used to indicate that the type is mentioned explicitly in a record
1817 -- representation clause, and thus is not inherited by a derived type.
1818 -- This flag is always False for non-record types.
1820 -- Has_Specified_Stream_Input (Flag190)
1821 -- Has_Specified_Stream_Output (Flag191)
1822 -- Has_Specified_Stream_Read (Flag192)
1823 -- Has_Specified_Stream_Write (Flag193)
1824 -- Defined in all type and subtype entities. Set for a given view if the
1825 -- corresponding stream-oriented attribute has been defined by an
1826 -- attribute definition clause. When such a clause occurs, a TSS is set
1827 -- on the underlying full view; the flags are used to track visibility of
1828 -- the attribute definition clause for partial or incomplete views.
1830 -- Has_Static_Discriminants (Flag211)
1831 -- Defined in record subtypes constrained by discriminant values. Set if
1832 -- all the discriminant values have static values, meaning that in the
1833 -- case of a variant record, the component list can be trimmed down to
1834 -- include only the components corresponding to these discriminants.
1836 -- Has_Static_Predicate_Aspect (Flag259)
1837 -- Defined in all types and subtypes. Set if a Dynamic_Predicate aspect
1838 -- applies to the type. Note that we can tell if a static predicate is
1839 -- present by looking at Has_Predicates and Static_Predicate, but that
1840 -- could have come from a Predicate aspect or pragma, and we need to
1841 -- record the difference so that we can use the right set of check
1842 -- policies to figure out if the predicate is active.
1844 -- Has_Storage_Size_Clause (Flag23) [implementation base type only]
1845 -- Defined in task types and access types. It is set if a Storage_Size
1846 -- clause is present for the type. Used to prevent multiple clauses for
1847 -- one type. Note that this flag is initially cleared for a derived type
1848 -- even though the Storage_Size for such a type is inherited from a
1849 -- Storage_Size clause given for the parent type. Note that in the case
1850 -- of access types, this flag is defined only in the root type, since a
1851 -- storage size clause cannot be given to a derived type.
1853 -- Has_Stream_Size_Clause (Flag184)
1854 -- Defined in all entities. It is set for types which have a Stream_Size
1855 -- clause attribute. Used to prevent multiple Stream_Size clauses for a
1856 -- given entity, and also whether it is necessary to check for a stream
1859 -- Has_Task (Flag30) [base type only]
1860 -- Defined in all type entities. Set on task types themselves, and also
1861 -- (recursively) on any composite type which has a component for which
1862 -- Has_Task is set. The meaning is that an allocator or declaration of
1863 -- such an object must create the required tasks. Note: the flag is not
1864 -- set on access types, even if they designate an object that Has_Task.
1866 -- Has_Thunks (Flag228)
1867 -- Applies to E_Constant entities marked Is_Tag. True for secondary tag
1868 -- referencing a dispatch table whose contents are pointers to thunks.
1870 -- Has_Unchecked_Union (Flag123) [base type only]
1871 -- Defined in all type entities. Set on unchecked unions themselves
1872 -- and (recursively) on any composite type which has a component for
1873 -- which Has_Unchecked_Union is set. The meaning is that a comparison
1874 -- operation for the type is not permitted. Note that the flag is not
1875 -- set on access types, even if they designate an object that has
1876 -- the flag Has_Unchecked_Union set.
1878 -- Has_Unknown_Discriminants (Flag72)
1879 -- Defined in all entities. Set for types with unknown discriminants.
1880 -- Types can have unknown discriminants either from their declaration or
1881 -- through type derivation. The use of this flag exactly meets the spec
1882 -- in RM 3.7(26). Note that all class-wide types are considered to have
1883 -- unknown discriminants. Note that both Has_Discriminants and
1884 -- Has_Unknown_Discriminants may be true for a type. Class-wide types and
1885 -- their subtypes have unknown discriminants and can have declared ones
1886 -- as well. Private types declared with unknown discriminants may have a
1887 -- full view that has explicit discriminants, and both flag will be set
1888 -- on the partial view, to insure that discriminants are properly
1889 -- inherited in certain contexts.
1891 -- Has_Up_Level_Access (Flag215)
1892 -- Defined in E_Variable and E_Constant entities. Set if the entity
1893 -- is a local variable declared in a subprogram p and is accessed in
1894 -- a subprogram nested inside p. Currently this flag is only set when
1895 -- VM_Target /= No_VM, for efficiency, since only the .NET back-end
1896 -- makes use of it to generate proper code for up-level references.
1898 -- Has_Volatile_Components (Flag87) [implementation base type only]
1899 -- Defined in all types and objects. Set only for an array type or array
1900 -- object if a valid pragma Volatile_Components or a valid pragma
1901 -- Atomic_Components applies to the type or object. Note that in the case
1902 -- of an object, this flag is only set on the object if there was an
1903 -- explicit pragma for the object. In other words, the proper test for
1904 -- whether an object has volatile components is to see if either the
1905 -- object or its base type has this flag set. Note that in the case of a
1906 -- type the pragma will be chained to the rep item chain of the first
1907 -- subtype in the usual manner.
1909 -- Has_Xref_Entry (Flag182)
1910 -- Defined in all entities. Set if an entity has an entry in the Xref
1911 -- information generated in ali files. This is true for all source
1912 -- entities in the extended main source file. It is also true of entities
1913 -- in other packages that are referenced directly or indirectly from the
1914 -- main source file (indirect reference occurs when the main source file
1915 -- references an entity with a type reference. See package Lib.Xref for
1916 -- further details).
1918 -- Hiding_Loop_Variable (Node8)
1919 -- Defined in variables. Set only if a variable of a discrete type is
1920 -- hidden by a loop variable in the same local scope, in which case
1921 -- the Hiding_Loop_Variable field of the hidden variable points to
1922 -- the E_Loop_Parameter entity doing the hiding. Used in processing
1923 -- warning messages if the hidden variable turns out to be unused
1924 -- or is referenced without being set.
1927 -- Defined in all entities. Link for list of entities that have the
1928 -- same source name and that are declared in the same or enclosing
1929 -- scopes. Homonyms in the same scope are overloaded. Used for name
1930 -- resolution and for the generation of debugging information.
1932 -- Implementation_Base_Type (synthesized)
1933 -- Applies to all entities. For types, similar to Base_Type, but never
1934 -- returns a private type when applied to a non-private type. Instead in
1935 -- this case, it always returns the Underlying_Type of the base type, so
1936 -- that we still have a concrete type. For entities other than types,
1937 -- returns the entity unchanged.
1939 -- In_Package_Body (Flag48)
1940 -- Defined in package entities. Set on the entity that denotes the
1941 -- package (the defining occurrence of the package declaration) while
1942 -- analyzing and expanding the package body. Reset on completion of
1943 -- analysis/expansion.
1945 -- In_Private_Part (Flag45)
1946 -- Defined in all entities. Can be set only in package entities and
1947 -- objects. For package entities, this flag is set to indicate that the
1948 -- private part of the package is being analyzed. The flag is reset at
1949 -- the end of the package declaration. For objects it indicates that the
1950 -- declaration of the object occurs in the private part of a package.
1952 -- Initialization_Statements (Node28)
1953 -- Defined in constants and variables. For a composite object initialized
1954 -- initialized with an aggregate that has been converted to a sequence
1955 -- of assignments, points to a block statement containing the
1958 -- Inner_Instances (Elist23)
1959 -- Defined in generic units. Contains element list of units that are
1960 -- instantiated within the given generic. Used to diagnose circular
1963 -- Integrity_Level (Uint8)
1964 -- Defined for E_Abstract_State entities. Contains the numerical value of
1965 -- the integrity level state property. A value of Uint_0 designates a non
1966 -- existent integrity.
1968 -- Interface_Alias (Node25)
1969 -- Defined in subprograms that cover a primitive operation of an abstract
1970 -- interface type. Can be set only if the Is_Hidden flag is also set,
1971 -- since such entities are always hidden. Points to its associated
1972 -- interface subprogram. It is used to register the subprogram in
1973 -- secondary dispatch table of the interface (Ada 2005: AI-251).
1975 -- Interface_Name (Node21)
1976 -- Defined in constants, variables, exceptions, functions, procedures,
1977 -- packages, components (JGNAT only), discriminants (JGNAT only), and
1978 -- access to subprograms (JGNAT only). Set to Empty unless an export,
1979 -- import, or interface name pragma has explicitly specified an external
1980 -- name, in which case it references an N_String_Literal node for the
1981 -- specified external name. In the case of exceptions, the field is set
1982 -- by Import_Exception/Export_Exception (which can be used in OpenVMS
1983 -- versions only). Note that if this field is Empty, and Is_Imported
1984 -- or Is_Exported is set, then the default interface name is the name
1985 -- of the entity, cased in a manner that is appropriate to the system
1986 -- in use. Note that Interface_Name is ignored if an address clause
1987 -- is present (since it is meaningless in this case).
1989 -- An additional special case usage of this field is in JGNAT for
1990 -- E_Component and E_Discriminant. JGNAT allows these entities to be
1991 -- imported by specifying pragma Import within a component's containing
1992 -- record definition. This supports interfacing to object fields defined
1993 -- within Java classes, and such pragmas are generated by the jvm2ada
1994 -- binding generator tool whenever it processes classes with public
1995 -- object fields. A pragma Import for a component can define the
1996 -- External_Name of the imported Java field (which is generally needed,
1997 -- because Java names are case sensitive).
1999 -- Interfaces (Elist25)
2000 -- Defined in record types and subtypes. List of abstract interfaces
2001 -- implemented by a tagged type that are not already implemented by the
2002 -- ancestors (Ada 2005: AI-251).
2004 -- Invariant_Procedure (synthesized)
2005 -- Defined in types and subtypes. Set for private types if one or more
2006 -- Invariant, or Invariant'Class, or inherited Invariant'Class aspects
2007 -- apply to the type. Points to the entity for a procedure which checks
2008 -- the invariant. This invariant procedure takes a single argument of the
2009 -- given type, and returns if the invariant holds, or raises exception
2010 -- Assertion_Error with an appropriate message if it does not hold. This
2011 -- attribute is defined but always empty for private subtypes. This
2012 -- attribute is also set for the corresponding full type.
2014 -- Note: the reason this is marked as a synthesized attribute is that the
2015 -- way this is stored is as an element of the Subprograms_For_Type field.
2018 -- Defined in packages and types. Set when analyzing a use clause for
2019 -- the corresponding entity. Reset at end of corresponding declarative

2044 -- applies to the entity which specifically names the entity, indicating
2045 -- that the entity is Ada 2005 only. Note that this flag is not set if

2047 -- of pragma Ada_05 or Ada_2005.
2049 -- Is_Ada_2012_Only (Flag199)
2050 -- Defined in all entities, true if a valid pragma Ada_12 or Ada_2012
2051 -- applies to the entity which specifically names the entity, indicating
2052 -- that the entity is Ada 2012 only. Note that this flag is not set if

2054 -- of pragma Ada_12 or Ada_2012.
2056 -- Is_Aliased (Flag15)
2057 -- Defined in all entities. Set for objects and types whose declarations
2058 -- carry the keyword aliased, and on record components that have the
2059 -- keyword. For Ada 2012, also applies to formal parameters.
2061 -- Is_AST_Entry (Flag132)
2062 -- Defined in entry entities. Set if a valid pragma AST_Entry applies
2063 -- to the entry. This flag can only be set in OpenVMS versions of GNAT.
2064 -- Note: we also allow the flag to appear in entry families, but given
2065 -- the current implementation of the pragma AST_Entry, this flag will
2066 -- always be False in entry families.
2068 -- Is_Atomic (Flag85)
2069 -- Defined in all type entities, and also in constants, components and
2070 -- variables. Set if a pragma Atomic or Shared applies to the entity.

2072 -- both the partial view and the full view.
2074 -- Is_Array_Type (synthesized)
2075 -- Applies to all entities, true for array types and subtypes
2077 -- Is_Asynchronous (Flag81)

2082 -- Applies to type and subtype entities. True if entity is a base type
2084 -- Is_Bit_Packed_Array (Flag122) [implementation base type only]
2085 -- Defined in all entities. This flag is set for a packed array type that
2086 -- is bit packed (i.e. the component size is known by the front end and
2087 -- is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed is always set
2088 -- if Is_Bit_Packed_Array is set, but it is possible for Is_Packed to be
2089 -- set without Is_Bit_Packed_Array for the case of an array having one or
2090 -- more index types that are enumeration types with non-standard
2091 -- enumeration representations.
2093 -- Is_Boolean_Type (synthesized)
2094 -- Applies to all entities, true for boolean types and subtypes,
2095 -- i.e. Standard.Boolean and all types ultimately derived from it.

2111 -- Applies to all entities, true for class wide types and subtypes
2113 -- Is_Class_Wide_Equivalent_Type (Flag35)
2114 -- Defined in record types and subtypes. Set to True, if the type acts

2116 -- some class-wide subtype entity references this record type.
2118 -- Is_Compilation_Unit (Flag149)
2119 -- Defined in all entities. Set if the entity is a package or subprogram
2120 -- entity for a compilation unit other than a subunit (since we treat
2121 -- subunits as part of the same compilation operation as the ultimate
2122 -- parent, we do not consider them to be separate units for this flag).
2124 -- Is_Completely_Hidden (Flag103)
2125 -- Defined in all entities. This flag can be set only for E_Discriminant
2126 -- entities. This flag can be set only for girder discriminants of
2127 -- untagged types. When set, the entity is a girder discriminant of a
2128 -- derived untagged type which is not directly visible in the derived
2129 -- type because the derived type or one of its ancestors have renamed the
2130 -- discriminants in the root type. Note: there are girder discriminants
2131 -- which are not Completely_Hidden (e.g. discriminants of a root type).
2133 -- Is_Composite_Type (synthesized)
2134 -- Applies to all entities, true for all composite types and
2135 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but

2138 -- Is_Concurrent_Record_Type (Flag20)
2139 -- Defined in record types and subtypes. Set if the type was created
2140 -- by the expander to represent a task or protected type. For every
2141 -- concurrent type, such as record type is constructed, and task and
2142 -- protected objects are instances of this record type at runtime
2143 -- (Gigi will replace declarations of the concurrent type using the

2159 -- Set if the type or subtype is constrained.
2161 -- Is_Constr_Subt_For_U_Nominal (Flag80)
2162 -- Defined in all types and subtypes. Set true only for the constructed
2163 -- subtype of an object whose nominal subtype is unconstrained. Note
2164 -- that the constructed subtype itself will be constrained.
2166 -- Is_Constr_Subt_For_UN_Aliased (Flag141)
2167 -- Defined in all types and subtypes. This flag can be set only if
2168 -- Is_Constr_Subt_For_U_Nominal is also set. It indicates that in
2169 -- addition the object concerned is aliased. This flag is used by
2170 -- Gigi to determine whether a template must be constructed.
2172 -- Is_Constructor (Flag76)
2173 -- Defined in function and procedure entities. Set if a pragma
2174 -- CPP_Constructor applies to the subprogram.

2178 -- i.e. is either a descendant of Ada.Finalization.Controlled or of
2179 -- Ada.Finalization.Limited_Controlled.
2181 -- Is_Controlling_Formal (Flag97)
2182 -- Defined in all Formal_Kind entities. Marks the controlling parameters
2183 -- of dispatching operations.
2185 -- Is_CPP_Class (Flag74)
2186 -- Defined in all type entities, set only for tagged types to which a
2187 -- valid pragma Import (CPP, ...) or pragma CPP_Class has been applied.
2189 -- Is_Decimal_Fixed_Point_Type (synthesized)
2190 -- Applies to all type entities, true for decimal fixed point
2191 -- types and subtypes.
2193 -- Is_Descendent_Of_Address (Flag223)
2194 -- Defined in all type and subtype entities. Indicates that a type is an
2195 -- address type that is visibly a numeric type. Used for semantic checks
2196 -- on VMS to remove ambiguities in universal integer expressions that may
2197 -- have an address interpretation
2199 -- Is_Discrete_Type (synthesized)
2200 -- Applies to all entities, true for all discrete types and subtypes
2202 -- Is_Discrete_Or_Fixed_Point_Type (synthesized)
2203 -- Applies to all entities, true for all discrete types and subtypes
2204 -- and all fixed-point types and subtypes.

2207 -- Defined in all entities. Set only in E_Function entities that Layout
2208 -- creates to compute discriminant-dependent dynamic size/offset values.
2210 -- Is_Discriminal (synthesized)
2211 -- Applies to all entities, true for renamings of discriminants. Such
2212 -- entities appear as constants or IN parameters.
2214 -- Is_Dispatch_Table_Entity (Flag234)
2215 -- Applies to all entities. Set to indicate to the backend that this
2216 -- entity is associated with a dispatch table.
2218 -- Is_Dispatching_Operation (Flag6)
2219 -- Defined in all entities. Set true for procedures, functions,
2220 -- generic procedures and generic functions if the corresponding
2221 -- operation is dispatching.
2223 -- Is_Dynamic_Scope (synthesized)
2224 -- Applies to all Entities. Returns True if the entity is a dynamic
2225 -- scope (i.e. a block, subprogram, task_type, entry
2226 -- or extended return statement).
2228 -- Is_Elementary_Type (synthesized)
2229 -- Applies to all entities, true for all elementary types and
2230 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
2231 -- not both) is true of any type.
2233 -- Is_Eliminated (Flag124)
2234 -- Defined in type entities, subprogram entities, and object entities.

2240 -- Defined in all entities, true for enumeration types and subtypes
2242 -- Is_Entry (synthesized)
2243 -- Applies to all entities, True only for entry and entry family
2244 -- entities and False for all other entity kinds.
2246 -- Is_Entry_Formal (Flag52)
2247 -- Defined in all entities. Set only for entry formals (which can
2248 -- only be in, in-out or out parameters). This flag is used to speed
2249 -- up the test for the need to replace references in Exp_Ch2.
2251 -- Is_Exported (Flag99)
2252 -- Defined in all entities. Set if the entity is exported. For now we
2253 -- only allow the export of constants, exceptions, functions, procedures
2254 -- and variables, but that may well change later on. Exceptions can only
2255 -- be exported in the OpenVMS and Java VM implementations of GNAT.
2257 -- Is_Finalizer (synthesized)
2258 -- Applies to all entities, true for procedures containing finalization
2259 -- code to process local or library level objects.
2261 -- Is_First_Subtype (Flag70)
2262 -- Defined in all entities. True for first subtypes (RM 3.2.1(6)),
2263 -- i.e. the entity in the type declaration that introduced the type.
2264 -- This may be the base type itself (e.g. for record declarations and
2265 -- enumeration type declarations), or it may be the first subtype of
2266 -- an anonymous base type (e.g. for integer type declarations or

2269 -- Is_Fixed_Point_Type (synthesized)
2270 -- Applies to all entities, true for decimal and ordinary fixed
2271 -- point types and subtypes

2283 -- Defined in all entities. Set for generic formal subprograms.
2285 -- Is_For_Access_Subtype (Flag118)
2286 -- Defined in E_Private_Subtype and E_Record_Subtype entities. Means the
2287 -- sole purpose of the type is to be designated by an Access_Subtype and
2288 -- hence should not be expanded into components because the type may not
2289 -- have been found or frozen yet.
2291 -- Is_Frozen (Flag4)
2292 -- Defined in all type and subtype entities. Set if type or subtype has
2295 -- Is_Generic_Actual_Type (Flag94)
2296 -- Defined in all type and subtype entities. Set in the subtype
2297 -- declaration that renames the generic formal as a subtype of the
2298 -- actual. Guarantees that the subtype is not static within the instance.
2300 -- Is_Generic_Instance (Flag130)
2301 -- Defined in all entities. Set to indicate that the entity is an
2302 -- instance of a generic unit, or a formal package (which is an instance
2303 -- of the template).
2305 -- Is_Generic_Subprogram (synthesized)
2306 -- Applies to all entities. Yields True for a generic subprogram
2307 -- (generic function, generic subprogram), False for all other entities.
2309 -- Is_Generic_Type (Flag13)
2310 -- Defined in all entities. Set for types which are generic formal types.
2311 -- Such types have an Ekind that corresponds to their classification, so
2312 -- the Ekind cannot be used to identify generic formal types.
2314 -- Is_Generic_Unit (synthesized)
2315 -- Applies to all entities. Yields True for a generic unit (generic
2316 -- package, generic function, generic procedure), and False for all
2319 -- Is_Ghost_Entity (synthesized)
2320 -- Applies to all entities. Yields True for a subprogram or a whole
2321 -- object that has convention Ghost.

2324 -- Applies to all entities. Yields True for a subprogram that has a Ghost
2327 -- Is_Hidden (Flag57)
2328 -- Defined in all entities. Set true for all entities declared in the
2329 -- private part or body of a package. Also marks generic formals of a
2330 -- formal package declared without a box. For library level entities,
2331 -- this flag is set if the entity is not publicly visible. This flag
2332 -- is reset when compiling the body of the package where the entity
2333 -- is declared, when compiling the private part or body of a public
2334 -- child unit, and when compiling a private child unit (see Install_
2335 -- Private_Declaration in sem_ch7).
2337 -- Is_Hidden_Open_Scope (Flag171)
2338 -- Defined in all entities. Set true for a scope that contains the
2339 -- instantiation of a child unit, and whose entities are not visible
2340 -- during analysis of the instance.
2342 -- Is_Immediately_Visible (Flag7)
2343 -- Defined in all entities. Set if entity is immediately visible, i.e.
2344 -- is defined in some currently open scope (RM 8.3(4)).
2346 -- Is_Implementation_Defined (Flag254)
2347 -- Defined in all entities. Set if a pragma Implementation_Defined is
2348 -- applied to the pragma. Used to mark all implementation defined
2349 -- identifiers in standard library packages, and to implement the
2350 -- restriction No_Implementation_Identifiers.
2352 -- Is_Imported (Flag24)
2353 -- Defined in all entities. Set if the entity is imported. For now we
2354 -- only allow the import of exceptions, functions, procedures, packages.
2355 -- and variables. Exceptions can only be imported in the OpenVMS and
2356 -- Java VM implementations of GNAT. Packages and types can only be
2357 -- imported in the Java VM implementation.

2360 -- Applies to all entities, true for private and incomplete types
2362 -- Is_Incomplete_Type (synthesized)
2363 -- Applies to all entities, true for incomplete types and subtypes
2365 -- Is_Inlined (Flag11)
2366 -- Defined in all entities. Set for functions and procedures which are
2367 -- to be inlined. For subprograms created during expansion, this flag
2368 -- may be set directly by the expander to request inlining. Also set
2369 -- for packages that contain inlined subprograms, whose bodies must be
2370 -- be compiled. Is_Inlined is also set on generic subprograms and is
2371 -- inherited by their instances. It is also set on the body entities
2372 -- of inlined subprograms. See also Has_Pragma_Inline.
2374 -- Is_Input_State (synthesized)
2375 -- Applies to all entities, true for abstract states that are subject to
2378 -- Is_Instantiated (Flag126)
2379 -- Defined in generic packages and generic subprograms. Set if the unit
2380 -- is instantiated from somewhere in the extended main source unit. This
2381 -- flag is used to control warnings about the unit being uninstantiated.
2382 -- Also set in a package that is used as an actual for a generic package
2383 -- formal in an instantiation. Also set on a parent instance, in the
2384 -- instantiation of a child, which is implicitly declared in the parent.
2386 -- Is_Integer_Type (synthesized)
2387 -- Applies to all entities, true for integer types and subtypes
2389 -- Is_Interface (Flag186)
2390 -- Defined in record types and subtypes. Set to indicate that the current
2391 -- entity corresponds with an abstract interface. Because abstract
2392 -- interfaces are conceptually a special kind of abstract tagged types
2393 -- we represent them by means of tagged record types and subtypes
2394 -- marked with this attribute. This allows us to reuse most of the
2395 -- compiler support for abstract tagged types to implement interfaces
2396 -- (Ada 2005: AI-251).
2398 -- Is_Internal (Flag17)
2399 -- Defined in all entities. Set to indicate an entity created during
2400 -- semantic processing (e.g. an implicit type, or a temporary). The
2401 -- current uses of this flag are:
2403 -- 1) Internal entities (such as temporaries generated for the result
2404 -- of an inlined function call or dummy variables generated for the
2405 -- debugger). Set to indicate that they need not be initialized, even
2406 -- when scalars are initialized or normalized;
2408 -- 2) Predefined primitives of tagged types. Set to mark that they
2409 -- have specific properties: first they are primitives even if they
2410 -- are not defined in the type scope (the freezing point is not
2411 -- necessarily in the same scope), and second the predefined equality
2412 -- can be overridden by a user-defined equality, no body will be
2413 -- generated in this case.
2415 -- 3) Object declarations generated by the expander that are implicitly
2416 -- imported or exported so that they can be marked in Sprint output.
2418 -- 4) Internal entities in the list of primitives of tagged types that
2419 -- are used to handle secondary dispatch tables. These entities have
2420 -- also the attribute Interface_Alias.
2422 -- Is_Interrupt_Handler (Flag89)
2423 -- Defined in procedures. Set if a pragma Interrupt_Handler applies
2424 -- to the procedure. The procedure must be parameterless, and on all
2425 -- targets except AAMP it must be a protected procedure.
2427 -- Is_Intrinsic_Subprogram (Flag64)
2428 -- Defined in functions and procedures. It is set if a valid pragma
2429 -- Interface or Import is present for this subprogram specifying pragma
2430 -- Intrinsic. Valid means that the name and profile of the subprogram
2431 -- match the requirements of one of the recognized intrinsic subprograms
2432 -- (see package Sem_Intr for details). Note: the value of Convention for
2433 -- such an entity will be set to Convention_Intrinsic, but it is the
2434 -- setting of Is_Intrinsic_Subprogram, NOT simply having convention set
2435 -- to intrinsic, which causes intrinsic code to be generated.
2437 -- Is_Invariant_Procedure (Flag257)
2438 -- Defined in functions an procedures. Set for a generated invariant
2439 -- procedure to identify it easily in the
2441 -- Is_Itype (Flag91)
2442 -- Defined in all entities. Set to indicate that a type is an Itype,
2443 -- which means that the declaration for the type does not appear
2444 -- explicitly in the tree. Instead gigi will elaborate the type when it
2445 -- is first used. Has_Delayed_Freeze can be set for Itypes, and the
2446 -- meaning is that the first use (the one which causes the type to be
2447 -- defined) will be the freeze node. Note that an important restriction
2448 -- on Itypes is that the first use of such a type (the one that causes it
2449 -- to be defined) must be in the same scope as the type.
2451 -- Is_Known_Non_Null (Flag37)
2452 -- Defined in all entities. Relevant (and can be set True) only for
2453 -- objects of an access type. It is set if the object is currently
2454 -- known to have a non-null value (meaning that no access checks
2455 -- are needed). The indication can for example come from assignment
2456 -- of an access parameter or an allocator whose value is known non-null.
2458 -- Note: this flag is set according to the sequential flow of the
2459 -- program, watching the current value of the variable. However,
2460 -- this processing can miss cases of changing the value of an aliased
2461 -- or constant object, so even if this flag is set, it should not
2462 -- be believed if the variable is aliased or volatile. It would
2463 -- be a little neater to avoid the flag being set in the first
2464 -- place in such cases, but that's trickier, and there is only
2465 -- one place that tests the value anyway.
2467 -- The flag is dynamically set and reset as semantic analysis and
2468 -- expansion proceeds. Its value is meaningless once the tree is
2469 -- fully constructed, since it simply indicates the last state.
2470 -- Thus this flag has no meaning to the back end.
2472 -- Is_Known_Null (Flag204)
2473 -- Defined in all entities. Relevant (and can be set True) only for
2474 -- objects of an access type. It is set if the object is currently known
2475 -- to have a null value (meaning that a dereference will surely raise
2476 -- constraint error exception). The indication can come from an
2477 -- assignment or object declaration.
2479 -- The comments above about sequential flow and aliased and volatile for
2480 -- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag.
2482 -- Is_Known_Valid (Flag170)
2483 -- Defined in all entities. Relevant for types (and subtype) and
2484 -- for objects (and enumeration literals) of a discrete type.
2486 -- The purpose of this flag is to implement the requirement stated
2487 -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
2488 -- values may not cause programs to become erroneous. See the function
2489 -- Checks.Expr_Known_Valid for further details. Note that the setting
2490 -- is conservative, in the sense that if the flag is set, it must be
2491 -- right. If the flag is not set, nothing is known about the validity.
2493 -- For enumeration literals, the flag is always set, since clearly
2494 -- an enumeration literal represents a valid value. Range checks
2495 -- where necessary will ensure that this valid value is appropriate.
2497 -- For objects, the flag indicates the state of knowledge about the
2498 -- current value of the object. This may be modified during expansion,
2499 -- and thus the final value is not relevant to gigi.
2501 -- For types and subtypes, the flag is set if all possible bit patterns
2502 -- of length Object_Size (i.e. Esize of the type) represent valid values
2503 -- of the type. In general for such tytpes, all values are valid, the
2504 -- only exception being the case where an object of the type has an
2505 -- explicit size that is greater than Object_Size.
2507 -- For non-discrete objects, the setting of the Is_Known_Valid flag is
2508 -- not defined, and is not relevant, since the considerations of the
2509 -- requirement in (RM 13.9.1(9-11)) do not apply.
2511 -- The flag is dynamically set and reset as semantic analysis and
2512 -- expansion proceeds. Its value is meaningless once the tree is
2513 -- fully constructed, since it simply indicates the last state.
2514 -- Thus this flag has no meaning to the back end.
2516 -- Is_Limited_Composite (Flag106)
2517 -- Defined in all entities. Set for composite types that have a limited
2518 -- component. Used to enforce the rule that operations on the composite
2519 -- type that depend on the full view of the component do not become
2520 -- visible until the immediate scope of the composite type itself
2523 -- Is_Limited_Interface (Flag197)
2524 -- Defined in record types and subtypes. True for interface types, if
2525 -- interface is declared limited, task, protected, or synchronized, or
2526 -- is derived from a limited interface.
2528 -- Is_Limited_Record (Flag25)
2529 -- Defined in all entities. Set to true for record (sub)types if the
2530 -- record is declared to be limited. Note that this flag is not set
2531 -- simply because some components of the record are limited.
2533 -- Is_Local_Anonymous_Access (Flag194)
2534 -- Defined in access types. Set for an anonymous access type to indicate
2535 -- that the type is created for a record component with an access
2536 -- definition, an array component, or (pre-Ada 2012) a standalone object.
2537 -- Such anonymous types have an accessibility level equal to that of the
2538 -- declaration in which they appear, unlike the anonymous access types
2539 -- that are created for access parameters, access discriminants, and
2540 -- (as of Ada 2012) stand-alone objects.
2542 -- Is_Machine_Code_Subprogram (Flag137)
2543 -- Defined in subprogram entities. Set to indicate that the subprogram
2544 -- is a machine code subprogram (i.e. its body includes at least one
2545 -- code statement). Also indicates that all necessary semantic checks
2546 -- as required by RM 13.8(3) have been performed.
2548 -- Is_Modular_Integer_Type (synthesized)
2549 -- Applies to all entities. True if entity is a modular integer type
2551 -- Is_Non_Static_Subtype (Flag109)
2552 -- Defined in all type and subtype entities. It is set in some (but not
2553 -- all) cases in which a subtype is known to be non-static. Before this
2554 -- flag was added, the computation of whether a subtype was static was
2555 -- entirely synthesized, by looking at the bounds, and the immediate
2556 -- subtype parent. However, this method does not work for some Itypes
2557 -- that have no parent set (and the only way to find the immediate
2558 -- subtype parent is to go through the tree). For now, this flag is set
2559 -- conservatively, i.e. if it is set then for sure the subtype is non-
2560 -- static, but if it is not set, then the type may or may not be static.
2561 -- Thus the test for a static subtype is that this flag is clear AND that
2562 -- the bounds are static AND that the parent subtype (if available to be
2563 -- tested) is static. Eventually we should make sure this flag is always
2564 -- set right, at which point, these comments can be removed, and the
2565 -- tests for static subtypes greatly simplified.
2567 -- Is_Null_Init_Proc (Flag178)
2568 -- Defined in procedure entities. Set for generated init proc procedures
2569 -- (used to initialize composite types), if the code for the procedure
2570 -- is null (i.e. is a return and nothing else). Such null initialization
2571 -- procedures are generated in case some client is compiled using the
2572 -- Initialize_Scalars pragma, generating a call to this null procedure,
2573 -- but there is no need to call such procedures within a compilation
2574 -- unit, and this flag is used to suppress such calls.
2576 -- Is_Null_State (synthesized)
2577 -- Applies to all entities, true for an abstract state declared with
2580 -- Is_Numeric_Type (synthesized)
2581 -- Applies to all entities, true for all numeric types and subtypes
2582 -- (integer, fixed, float).
2584 -- Is_Object (synthesized)
2585 -- Applies to all entities, true for entities representing objects,
2586 -- including generic formal parameters.
2588 -- Is_Obsolescent (Flag153)
2589 -- Defined in all entities. Set for any entity for which a valid pragma
2590 -- Obsolescent applies.
2592 -- Is_Only_Out_Parameter (Flag226)
2593 -- Defined in formal parameter entities. Set if this parameter is the
2594 -- only OUT parameter for this formal part. If there is more than one
2595 -- out parameter, or if there is some other IN OUT parameter then this
2596 -- flag is not set in any of them. Used in generation of warnings.
2598 -- Is_Optional_Parameter (Flag134)
2599 -- Defined in parameter entities. Set if the parameter is specified as
2600 -- optional by use of a First_Optional_Parameter argument to one of the
2601 -- extended Import pragmas. Can only be set for OpenVMS versions of GNAT.
2603 -- Is_Ordinary_Fixed_Point_Type (synthesized)
2604 -- Applies to all entities, true for ordinary fixed point types and
2607 -- Is_Output_State (synthesized)
2608 -- Applies to all entities, true for abstract states that are subject to
2611 -- Is_Package_Or_Generic_Package (synthesized)
2612 -- Applies to all entities. True for packages and generic packages.
2613 -- False for all other entities.
2615 -- Is_Package_Body_Entity (Flag160)
2616 -- Defined in all entities. Set for entities defined at the top level
2617 -- of a package body. Used to control externally generated names.
2619 -- Is_Packed (Flag51) [implementation base type only]
2620 -- Defined in all type entities. This flag is set only for record and
2621 -- array types which have a packed representation. There are three
2622 -- cases which cause packing:
2624 -- 1. Explicit use of pragma Pack for an array of package components
2625 -- 2. Explicit use of pragma Pack to pack a record
2626 -- 4. Setting Component_Size of an array to a bit-packable value
2627 -- 3. Indexing an array with a non-standard enumeration type.
2629 -- For records, Is_Packed is always set if Has_Pragma_Pack is set,
2630 -- and can also be set on its own in a derived type which inherited
2631 -- its packed status.
2633 -- For arrays, Is_Packed is set if an array is bit packed (i.e. the
2634 -- component size is known at compile time and is 1-7, 9-15 or 17-31),
2635 -- or if the array has one or more index types that are enumeration
2636 -- types with non-standard representations (in GNAT, we store such
2637 -- arrays compactly, using the Pos of the enumeration type value).
2639 -- As for the case of records, Is_Packed can be set on its own for a
2640 -- derived type, with the same dual before/after freeze meaning.
2641 -- Is_Packed can also be set as the result of an explicit component
2642 -- size clause that specifies an appropriate component size.
2644 -- In the bit packed array case, Is_Bit_Packed_Array will be set in
2645 -- the bit packed case once the array type is frozen.
2647 -- Before an array type is frozen, Is_Packed will always be set if
2648 -- Has_Pragma_Pack is set. Before the freeze point, it is not possible
2649 -- to know the component size, since the component type is not frozen
2650 -- until the array type is frozen. Thus Is_Packed for an array type
2651 -- before it is frozen means that packed is required. Then if it turns
2652 -- out that the component size is not suitable for bit packing, the
2653 -- Is_Packed flag gets turned off.
2655 -- Is_Packed_Array_Type (Flag138)
2656 -- Defined in all entities. This flag is set on the entity for the type
2657 -- used to implement a packed array (either a modular type, or a subtype
2658 -- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
2659 -- if the type appears in the Packed_Array_Type field of some other type
2660 -- entity. It is used by Gigi to activate the special processing for such
2661 -- types (unchecked conversions that would not otherwise be allowed are
2662 -- allowed for such types). If the Is_Packed_Array_Type flag is set in
2663 -- an entity, then the Original_Array_Type field of this entity points
2664 -- to the original array type for which this is the packed array type.
2666 -- Is_Potentially_Use_Visible (Flag9)
2667 -- Defined in all entities. Set if entity is potentially use visible,
2668 -- i.e. it is defined in a package that appears in a currently active
2669 -- use clause (RM 8.4(8)). Note that potentially use visible entities
2670 -- are not necessarily use visible (RM 8.4(9-11)).
2672 -- Is_Predicate_Function (Flag255)
2673 -- Present in functions and procedures. Set for generated predicate
2676 -- Is_Predicate_Function_M (Flag256)
2677 -- Present in functions and procedures. Set for special version of
2678 -- predicate function generated for use in membership tests, where
2679 -- raise expressions are transformed to return False.
2681 -- Is_Preelaborated (Flag59)
2682 -- Defined in all entities, set in E_Package and E_Generic_Package
2683 -- entities to which a pragma Preelaborate is applied, and also in
2684 -- all entities within such packages. Note that the fact that this
2685 -- flag is set does not necesarily mean that no elaboration code is
2686 -- generated for the package.
2688 -- Is_Primitive (Flag218)
2689 -- Defined in overloadable entities and in generic subprograms. Set to
2690 -- indicate that this is a primitive operation of some type, which may
2691 -- be a tagged type or a non-tagged type. Used to verify overriding
2692 -- indicators in bodies.
2694 -- Is_Primitive_Wrapper (Flag195)
2695 -- Defined in functions and procedures created by the expander to serve
2696 -- as an indirection mechanism to overriding primitives of concurrent
2697 -- types, entries and protected procedures.
2699 -- Is_Prival (synthesized)
2700 -- Applies to all entities, true for renamings of private protected
2701 -- components. Such entities appear as constants or variables.
2703 -- Is_Private_Composite (Flag107)
2704 -- Defined in composite types that have a private component. Used to
2705 -- enforce the rule that operations on the composite type that depend
2706 -- on the full view of the component, do not become visible until the
2707 -- immediate scope of the composite type itself (7.3.1 (5)). Both this
2708 -- flag and Is_Limited_Composite are needed.
2710 -- Is_Private_Descendant (Flag53)
2711 -- Defined in entities that can represent library units (packages,
2712 -- functions, procedures). Set if the library unit is itself a private
2713 -- child unit, or if it is the descendent of a private child unit.
2715 -- Is_Private_Primitive (Flag245)
2716 -- Defined in subprograms. Set if the operation is a primitive of a
2717 -- tagged type (procedure or function dispatching on result) whose
2718 -- full view has not been seen. Used in particular for primitive
2719 -- subprograms of a synchronized type declared between the two views
2720 -- of the type, so that the wrapper built for such a subprogram can
2721 -- be given the proper signature.
2723 -- Is_Private_Type (synthesized)
2724 -- Applies to all entities, true for private types and subtypes,
2725 -- as well as for record with private types as subtypes
2727 -- Is_Processed_Transient (Flag252)
2728 -- Defined in entities of variables and constants. Set when a transient
2729 -- object needs to be finalized and it has already been processed by the
2730 -- transient scope machinery. This flag signals the general finalization
2731 -- mechanism to ignore the transient object.
2733 -- Is_Protected_Component (synthesized)
2734 -- Applicable to all entities, true if the entity denotes a private
2735 -- component of a protected type.
2737 -- Is_Protected_Interface (synthesized)
2738 -- Defined in types that are interfaces. True if interface is declared
2739 -- protected, or is derived from protected interfaces.
2741 -- Is_Protected_Type (synthesized)
2742 -- Applies to all entities, true for protected types and subtypes
2744 -- Is_Public (Flag10)
2745 -- Defined in all entities. Set to indicate that an entity defined in
2746 -- one compilation unit can be referenced from other compilation units.
2747 -- If this reference causes a reference in the generated variable, for
2748 -- example in the case of a variable name, then Gigi will generate an
2749 -- appropriate external name for use by the linker.
2751 -- Is_Protected_Record_Type (synthesized)
2752 -- Applies to all entities, true if Is_Concurrent_Record_Type is true and
2753 -- Corresponding_Concurrent_Type is a protected type.
2756 -- Defined in all entities. Set in all entities of a unit to which a
2757 -- pragma Pure is applied, and also set for the entity of the unit
2758 -- itself. In addition, this flag may be set for any other functions
2759 -- or procedures that are known to be side effect free, so in the case
2760 -- of subprograms, the Is_Pure flag may be used by the optimizer to
2761 -- imply that it can assume freedom from side effects (other than those
2762 -- resulting from assignment to out parameters, or to objects designated
2763 -- by access parameters).
2765 -- Is_Pure_Unit_Access_Type (Flag189)
2766 -- Defined in access type and subtype entities. Set if the type or
2767 -- subtype appears in a pure unit. Used to give an error message at
2768 -- freeze time if the access type has a storage pool.
2770 -- Is_RACW_Stub_Type (Flag244)
2771 -- Defined in all types, true for the stub types generated for remote
2772 -- access-to-class-wide types.
2774 -- Is_Raised (Flag224)
2775 -- Defined in exception entities. Set if the entity is referenced by a
2776 -- a raise statement.
2778 -- Is_Real_Type (synthesized)
2779 -- Applies to all entities, true for real types and subtypes
2781 -- Is_Record_Type (synthesized)
2782 -- Applies to all entities, true for record types and subtypes,
2783 -- includes class-wide types and subtypes (which are also records)
2785 -- Is_Remote_Call_Interface (Flag62)
2786 -- Defined in all entities. Set in E_Package and E_Generic_Package
2787 -- entities to which a pragma Remote_Call_Interface is applied, and
2788 -- also on entities declared in the visible part of such a package.
2790 -- Is_Remote_Types (Flag61)
2791 -- Defined in all entities. Set in E_Package and E_Generic_Package
2792 -- entities to which a pragma Remote_Types is applied, and also on
2793 -- entities declared in the visible part of the spec of such a package.
2794 -- Also set for types which are generic formal types to which the
2795 -- pragma Remote_Access_Type applies.
2797 -- Is_Renaming_Of_Object (Flag112)
2798 -- Defined in all entities, set only for a variable or constant for
2799 -- which the Renamed_Object field is non-empty and for which the
2800 -- renaming is handled by the front end, by macro substitution of
2801 -- a copy of the (evaluated) name tree whereever the variable is used.
2803 -- Is_Return_Object (Flag209)
2804 -- Defined in all object entities. True if the object is the return
2805 -- object of an extended_return_statement; False otherwise.
2807 -- Is_Safe_To_Reevaluate (Flag249)
2808 -- Defined in all entities. Set in variables that are initialized by
2809 -- means of an assignment statement. When initialized their contents
2810 -- never change and hence they can be seen by the backend as constants.
2811 -- See also Is_True_Constant.
2813 -- Is_Scalar_Type (synthesized)
2814 -- Applies to all entities, true for scalar types and subtypes
2816 -- Is_Shared_Passive (Flag60)
2817 -- Defined in all entities. Set in E_Package and E_Generic_Package
2818 -- entities to which a pragma Shared_Passive is applied, and also in
2819 -- all entities within such packages.
2821 -- Is_Standard_Character_Type (synthesized)
2822 -- Applies to all entities, true for types and subtypes whose root type
2823 -- is one of the standard character types (Character, Wide_Character,
2824 -- Wide_Wide_Character).
2826 -- Is_Statically_Allocated (Flag28)
2827 -- Defined in all entities. This can only be set True for exception,
2828 -- variable, constant, and type/subtype entities. If the flag is set,
2829 -- then the variable or constant must be allocated statically rather
2830 -- than on the local stack frame. For exceptions, the meaning is that
2831 -- the exception data should be allocated statically (and indeed this
2832 -- flag is always set for exceptions, since exceptions do not have
2833 -- local scope). For a type, the meaning is that the type must be
2834 -- elaborated at the global level rather than locally. No type marked
2835 -- with this flag may depend on a local variable, or on any other type
2836 -- which does not also have this flag set to True. For a variable or
2837 -- or constant, if the flag is set, then the type of the object must
2838 -- either be declared at the library level, or it must also have the
2839 -- flag set (since to allocate the object statically, its type must
2840 -- also be elaborated globally).
2842 -- Is_String_Type (synthesized)
2843 -- Applies to all type entities. Determines if the given type is a
2844 -- string type, i.e. it is directly a string type or string subtype,
2845 -- or a string slice type, or an array type with one dimension and a
2846 -- component type that is a character type.
2848 -- Is_Subprogram (synthesized)
2849 -- Applies to all entities, true for function, procedure and operator
2852 -- Is_Synchronized_Interface (synthesized)
2853 -- Defined in types that are interfaces. True if interface is declared
2854 -- synchronized, task, or protected, or is derived from a synchronized
2858 -- Defined in E_Component and E_Constant entities. For regular tagged
2859 -- type this flag is set on the tag component (whose name is Name_uTag).
2860 -- For CPP_Class tagged types, this flag marks the pointer to the main
2861 -- vtable (i.e. the one to be extended by derivation).
2863 -- Is_Tagged_Type (Flag55)
2864 -- Defined in all entities. Set for an entity for a tagged type.
2866 -- Is_Task_Interface (synthesized)
2867 -- Defined in types that are interfaces. True if interface is declared as
2868 -- a task interface, or if it is derived from task interfaces.
2870 -- Is_Task_Record_Type (synthesized)
2871 -- Applies to all entities. True if Is_Concurrent_Record_Type
2872 -- Corresponding_Concurrent_Type is a task type.
2874 -- Is_Task_Type (synthesized)
2875 -- Applies to all entities. True for task types and subtypes
2877 -- Is_Thunk (Flag225)
2878 -- Defined in all entities. True for subprograms that are thunks: that is
2879 -- small subprograms built by the expander for tagged types that cover
2880 -- interface types. As part of the runtime call to an interface, thunks
2881 -- displace the pointer to the object (pointer named "this" in the C++
2882 -- terminology) from a secondary dispatch table to the primary dispatch
2883 -- table associated with a given tagged type; if the thunk is a function
2884 -- that returns an object which covers an interface type then the thunk
2885 -- displaces the pointer to the object from the primary dispatch table to
2886 -- the secondary dispatch table associated with the interface type. Set
2887 -- by Expand_Interface_Thunk and used by Expand_Call to handle extra
2888 -- actuals associated with accessibility level.
2890 -- Is_Trivial_Subprogram (Flag235)
2891 -- Defined in all entities. Set in subprograms where either the body
2892 -- consists of a single null statement, or the first or only statement
2893 -- of the body raises an exception. This is used for suppressing certain
2894 -- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details.
2896 -- Is_True_Constant (Flag163)
2897 -- Defined in all entities for constants and variables. Set in constants
2898 -- and variables which have an initial value specified but which are
2899 -- never assigned, partially or in the whole. For variables, it means
2900 -- that the variable was initialized but never modified, and hence can be
2901 -- treated as a constant by the code generator. For a constant, it means
2902 -- that the constant was not modified by generated code (e.g. to set a
2903 -- discriminant in an init proc). Assignments by user or generated code
2904 -- will reset this flag. See also Is_Safe_To_Reevaluate.
2906 -- Is_Type (synthesized)
2907 -- Applies to all entities, true for a type entity
2909 -- Is_Unchecked_Union (Flag117) [implementation base type only]
2910 -- Defined in all entities. Set only in record types to which the
2911 -- pragma Unchecked_Union has been validly applied.
2913 -- Is_Underlying_Record_View (Flag246) [base type only]
2914 -- Defined in all entities. Set only in record types that represent the
2915 -- underlying record view. This view is built for derivations of types
2916 -- with unknown discriminants; it is a record with the same structure
2917 -- as its corresponding record type, but whose parent is the full view
2918 -- of the parent in the original type extension.
2920 -- Is_Unsigned_Type (Flag144)
2921 -- Defined in all types, but can be set only for discrete and fixed-point
2922 -- type and subtype entities. This flag is only valid if the entity is
2923 -- frozen. If set it indicates that the representation is known to be
2924 -- unsigned (i.e. that no negative values appear in the range). This is
2925 -- normally just a reflection of the lower bound of the subtype or base
2926 -- type, but there is one case in which the setting is non-obvious,
2927 -- namely the case of an unsigned subtype of a signed type from which
2928 -- a further subtype is obtained using variable bounds. This further
2929 -- subtype is still unsigned, but this cannot be determined by looking
2930 -- at its bounds or the bounds of the corresponding base type.
2932 -- Is_Valued_Procedure (Flag127)
2933 -- Defined in procedure entities. Set if an Import_Valued_Procedure
2934 -- or Export_Valued_Procedure pragma applies to the procedure entity.
2936 -- Is_Visible_Formal (Flag206)
2937 -- Defined in all entities. Set True for instances of the formals of a
2938 -- formal package. Indicates that the entity must be made visible in the
2939 -- body of the instance, to reproduce the visibility of the generic.
2940 -- This simplifies visibility settings in instance bodies.
2942 -- Is_Visible_Lib_Unit (Flag116)
2943 -- Defined in all (root or child) library unit entities. Once compiled,
2944 -- library units remain chained to the entities in the parent scope, and
2945 -- a separate flag must be used to indicate whether the names are visible
2946 -- by selected notation, or not.
2948 -- Is_VMS_Exception (Flag133)
2949 -- Defined in all entities. Set only for exception entities where the
2950 -- exception was specified in an Import_Exception or Export_Exception
2951 -- pragma with the VMS option for Form. See description of these pragmas
2952 -- for details. This flag can only be set in OpenVMS versions of GNAT.
2954 -- Is_Volatile (Flag16)
2955 -- Defined in all type entities, and also in constants, components and
2956 -- variables. Set if a pragma Volatile applies to the entity. Also set
2957 -- if pragma Shared or pragma Atomic applies to entity. In the case of
2958 -- private or incomplete types, this flag is set in both the private
2959 -- and full view. The flag is not set reliably on private subtypes,
2960 -- and is always retrieved from the base type (but this is not a base-
2961 -- type-only attribute because it applies to other entities). Note that
2962 -- the back end should use Treat_As_Volatile, rather than Is_Volatile
2963 -- to indicate code generation requirements for volatile variables.
2964 -- Similarly, any front end test which is concerned with suppressing
2965 -- optimizations on volatile objects should test Treat_As_Volatile
2966 -- rather than testing this flag.
2968 -- Is_Volatile_State (synthesized)
2969 -- Applies to all entities, true for abstract states that are subject to
2970 -- property Volatile.
2972 -- Is_Wrapper_Package (synthesized)
2973 -- Defined in package entities. Indicates that the package has been
2974 -- created as a wrapper for a subprogram instantiation.
2976 -- Itype_Printed (Flag202)
2977 -- Defined in all type and subtype entities. Set in Itypes if the Itype
2978 -- has been printed by Sprint. This is used to avoid printing an Itype
2981 -- Kill_Elaboration_Checks (Flag32)
2982 -- Defined in all entities. Set by the expander to kill elaboration
2983 -- checks which are known not to be needed. Equivalent in effect to
2984 -- the use of pragma Suppress (Elaboration_Checks) for that entity
2985 -- except that the effect is permanent and cannot be undone by a
2986 -- subsequent pragma Unsuppress.
2988 -- Kill_Range_Checks (Flag33)
2989 -- Defined in all entities. Equivalent in effect to the use of pragma
2990 -- Suppress (Range_Checks) for that entity except that the result is
2991 -- permanent and cannot be undone by a subsequent pragma Unsuppress.
2992 -- This is currently only used in one odd situation in Sem_Ch3 for
2993 -- record types, and it would be good to get rid of it???
2995 -- Known_To_Have_Preelab_Init (Flag207)
2996 -- Defined in all type and subtype entities. If set, then the type is
2997 -- known to have preelaborable initialization. In the case of a partial
2998 -- view of a private type, it is only possible for this to be set if a
2999 -- pragma Preelaborable_Initialization is given for the type. For other
3000 -- types, it is never set if the type does not have preelaborable
3001 -- initialization, it may or may not be set if the type does have
3002 -- preelaborable initialization.
3004 -- Last_Assignment (Node26)
3005 -- Defined in entities for variables, and OUT or IN OUT formals. Set for
3006 -- a local variable or formal to point to the left side of an assignment
3007 -- statement assigning a value to the variable. Cleared if the value of
3008 -- the entity is referenced. Used to warn about dubious assignment
3009 -- statements whose value is not used.
3011 -- Last_Entity (Node20)
3012 -- Defined in all entities which act as scopes to which a list of
3013 -- associated entities is attached (blocks, class subtypes and types,
3014 -- entries, functions, loops, packages, procedures, protected objects,
3015 -- record types and subtypes, private types, task types and subtypes).
3016 -- Points to the last entry in the list of associated entities chained
3017 -- through the Next_Entity field. Empty if no entities are chained.
3019 -- Last_Formal (synthesized)
3020 -- Applies to subprograms and subprogram types, and also in entries
3021 -- and entry families. Returns last formal of the subprogram or entry.
3022 -- The formals are the first entities declared in a subprogram or in
3023 -- a subprogram type (the designated type of an Access_To_Subprogram
3024 -- definition) or in an entry.
3026 -- Limited_View (Node23)
3027 -- Defined in non-generic package entities that are not instances. Bona
3028 -- fide package with the limited-view list through the first_entity and
3029 -- first_private attributes. The elements of this list are the shadow
3030 -- entities created for the types and local packages that are declared
3031 -- in a package appearing in a limited_with clause (Ada 2005: AI-50217)
3033 -- Lit_Indexes (Node15)
3034 -- Defined in enumeration types and subtypes. Non-empty only for the
3035 -- case of an enumeration root type, where it contains the entity for
3036 -- the generated indexes entity. See unit Exp_Imgv for full details of
3037 -- the nature and use of this entity for implementing the Image and
3038 -- Value attributes for the enumeration type in question.
3040 -- Lit_Strings (Node16)
3041 -- Defined in enumeration types and subtypes. Non-empty only for the
3042 -- case of an enumeration root type, where it contains the entity for
3043 -- the literals string entity. See unit Exp_Imgv for full details of
3044 -- the nature and use of this entity for implementing the Image and
3045 -- Value attributes for the enumeration type in question.
3047 -- Low_Bound_Tested (Flag205)
3048 -- Defined in all entities. Currently this can only be set True for
3049 -- formal parameter entries of a standard unconstrained one-dimensional
3050 -- array or string type. Indicates that an explicit test of the low bound
3051 -- of the formal appeared in the code, e.g. in a pragma Assert. If this
3052 -- flag is set, warnings about assuming the index low bound to be one
3055 -- Machine_Radix_10 (Flag84)
3056 -- Defined in decimal types and subtypes, set if the Machine_Radix is 10,
3057 -- as the result of the specification of a machine radix representation
3058 -- clause. Note that it is possible for this flag to be set without
3059 -- having Has_Machine_Radix_Clause True. This happens when a type is
3060 -- derived from a type with a clause present.
3062 -- Master_Id (Node17)
3063 -- Defined in access types and subtypes. Empty unless Has_Task is
3064 -- set for the designated type, in which case it points to the entity
3065 -- for the Master_Id for the access type master. Also set for access-to-
3066 -- limited-class-wide types whose root may be extended with task
3067 -- components, and for access-to-limited-interfaces because they can be
3068 -- used to reference tasks implementing such interface.
3070 -- Materialize_Entity (Flag168)
3071 -- Defined in all entities. Set only for renamed obects which should be
3072 -- materialized for debugging purposes. This means that a memory location
3073 -- containing the renamed address should be allocated. This is needed so
3074 -- that the debugger can find the entity.
3076 -- Mechanism (Uint8) (returned as Mechanism_Type)
3077 -- Defined in functions and non-generic formal parameters. Indicates
3078 -- the mechanism to be used for the function return or for the formal
3079 -- parameter. See separate section on passing mechanisms. This field
3080 -- is also set (to the default value of zero) in a subprogram body
3081 -- entity but not used in this context.
3083 -- Modulus (Uint17) [base type only]
3084 -- Defined in modular types. Contains the modulus. For the binary case,
3085 -- this will be a power of 2, but if Non_Binary_Modulus is set, then it
3086 -- will not be a power of 2.
3088 -- Must_Be_On_Byte_Boundary (Flag183)
3089 -- Defined in entities for types and subtypes. Set if objects of the type
3090 -- must always be allocated on a byte boundary (more accurately a storage
3091 -- unit boundary). The front end checks that component clauses respect
3092 -- this rule, and the back end ensures that record packing does not
3093 -- violate this rule. Currently the flag is set only for packed arrays
3094 -- longer than 64 bits where the component size is not a power of 2.
3096 -- Must_Have_Preelab_Init (Flag208)
3097 -- Defined in entities for types and subtypes. Set in the full type of a
3098 -- private type or subtype if a pragma Has_Preelaborable_Initialization
3099 -- is present for the private type. Used to check that the full type has
3100 -- preelaborable initialization at freeze time (this has to be deferred
3101 -- to the freeze point because of the rule about overriding Initialize).
3103 -- Needs_Debug_Info (Flag147)
3104 -- Defined in all entities. Set if the entity requires normal debugging
3105 -- information to be generated. This is true of all entities that have
3106 -- Comes_From_Source set, and also transitively for entities associated
3107 -- with such components (e.g. their types). It is true for all entities
3108 -- in Debug_Generated_Code mode (-gnatD switch). This is the flag that
3109 -- the back end should check to determine whether or not to generate
3110 -- debugging information for an entity. Note that callers should always
3111 -- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info,
3112 -- so that the flag is set properly on subsidiary entities.
3114 -- Needs_No_Actuals (Flag22)
3115 -- Defined in callable entities (subprograms, entries, access to
3116 -- subprograms) which can be called without actuals because all of
3117 -- their formals (if any) have default values. This flag simplifies the
3118 -- resolution of the syntactic ambiguity involving a call to these
3119 -- entities when the return type is an array type, and a call can be
3120 -- interpreted as an indexing of the result of the call. It is also
3121 -- used to resolve various cases of entry calls.
3123 -- Never_Set_In_Source (Flag115)
3124 -- Defined in all entities, but can be set only for variables and
3125 -- parameters. This flag is set if the object is never assigned a value
3126 -- in user source code, either by assignment or by being used as an out
3127 -- or in out parameter. Note that this flag is not reset from using an
3128 -- initial value, so if you want to test for this case as well, test the
3129 -- Has_Initial_Value flag also.
3131 -- This flag is only for the purposes of issuing warnings, it must not
3132 -- be used by the code generator to indicate that the variable is in
3133 -- fact a constant, since some assignments in generated code do not
3134 -- count (for example, the call to an init proc to assign some but
3135 -- not all of the fields in a partially initialized record). The code
3136 -- generator should instead use the flag Is_True_Constant.
3138 -- For the purposes of this warning, the default assignment of
3139 -- access variables to null is not considered the assignment of
3140 -- of a value (so the warning can be given for code that relies
3141 -- on this initial null value, when no other value is ever set).
3143 -- In variables and out parameters, if this flag is set after full
3144 -- processing of the corresponding declarative unit, it indicates that
3145 -- the variable or parameter was never set, and a warning message can
3148 -- Note: this flag is initially set, and then cleared on encountering
3149 -- any construct that might conceivably legitimately set the value.
3150 -- Thus during the analysis of a declarative region and its associated
3151 -- statement sequence, the meaning of the flag is "not set yet", and
3152 -- once this analysis is complete the flag means "never assigned".
3154 -- Note: for variables appearing in package declarations, this flag
3155 -- is never set. That is because there is no way to tell if some
3156 -- client modifies the variable (or in the case of variables in the
3157 -- private part, if some child unit modifies the variables).
3159 -- Note: in the case of renamed objects, the flag must be set in the
3160 -- ultimate renamed object. Clients noting a possible modification
3161 -- should use the Note_Possible_Modification procedure in Sem_Util
3162 -- rather than Set_Never_Set_In_Source precisely to deal properly with
3163 -- the renaming possibility.
3165 -- Next_Component (synthesized)
3166 -- Applies to record components. Returns the next component by following
3167 -- the chain of declared entities until one is found which corresponds to
3168 -- a component (Ekind is E_Component). Any internal types generated from
3169 -- the subtype indications of the record components are skipped. Returns
3170 -- Empty if no more components.
3172 -- Next_Component_Or_Discriminant (synthesized)
3173 -- Similar to Next_Component, but includes components and discriminants
3174 -- so the input can have either E_Component or E_Discriminant, and the
3175 -- same is true for the result. Returns Empty if no more components or
3176 -- discriminants in the record.
3178 -- Next_Discriminant (synthesized)
3179 -- Applies to discriminants returned by First/Next_Discriminant.
3180 -- Returns the next language-defined (ie: perhaps non-girder)
3181 -- discriminant by following the chain of declared entities as long as
3182 -- the kind of the entity corresponds to a discriminant. Note that the
3183 -- discriminants might be the only components of the record.
3184 -- Returns Empty if there are no more.
3186 -- Next_Entity (Node2)
3187 -- Defined in all entities. The entities of a scope are chained, with
3188 -- the head of the list being in the First_Entity field of the scope
3189 -- entity. All entities use the Next_Entity field as a forward pointer
3190 -- for this list, with Empty indicating the end of the list. Since this
3191 -- field is in the base part of the entity, the access routines for this
3192 -- field are in Sinfo.
3194 -- Next_Formal (synthesized)
3195 -- Applies to the entity for a formal parameter. Returns the next
3196 -- formal parameter of the subprogram or subprogram type. Returns
3197 -- Empty if there are no more formals.
3199 -- Next_Formal_With_Extras (synthesized)
3200 -- Applies to the entity for a formal parameter. Returns the next
3201 -- formal parameter of the subprogram or subprogram type. Returns
3202 -- Empty if there are no more formals. The list returned includes
3203 -- all the extra formals (see description of Extra_Formal field)
3205 -- Next_Index (synthesized)
3206 -- Applies to array types and subtypes and to string types and
3207 -- subtypes. Yields the next index. The first index is obtained by
3208 -- using the First_Index attribute, and then subsequent indexes are
3209 -- obtained by applying Next_Index to the previous index. Empty is
3210 -- returned to indicate that there are no more indexes. Note that
3211 -- unlike most attributes in this package, Next_Index applies to
3212 -- nodes for the indexes, not to entities.
3214 -- Next_Inlined_Subprogram (Node12)
3215 -- Defined in subprograms. Used to chain inlined subprograms used in
3216 -- the current compilation, in the order in which they must be compiled
3217 -- by Gigi to insure that all inlinings are performed.
3219 -- Next_Literal (synthesized)
3220 -- Applies to enumeration literals, returns the next literal, or
3221 -- Empty if applied to the last literal. This is actually a synonym
3222 -- for Next, but its use is preferred in this context.
3224 -- Non_Binary_Modulus (Flag58) [base type only]
3225 -- Defined in all subtype and type entities. Set for modular integer
3226 -- types if the modulus value is other than a power of 2.
3228 -- Non_Limited_View (Node17)
3229 -- Defined in incomplete types that are the shadow entities created
3230 -- when analyzing a limited_with_clause (Ada 2005: AI-50217). Points to
3231 -- the defining entity in the original declaration.
3233 -- Nonzero_Is_True (Flag162) [base type only]
3234 -- Defined in enumeration types. True if any non-zero value is to be
3235 -- interpreted as true. Currently this is set true for derived Boolean
3236 -- types which have a convention of C, C++ or Fortran.
3238 -- No_Pool_Assigned (Flag131) [root type only]
3239 -- Defined in access types. Set if a storage size clause applies to the
3240 -- variable with a static expression value of zero. This flag is used to
3241 -- generate errors if any attempt is made to allocate or free an instance
3242 -- of such an access type. This is set only in the root type, since
3243 -- derived types must have the same pool.
3245 -- No_Return (Flag113)
3246 -- Defined in all entities. Always false except in the case of procedures
3247 -- and generic procedures for which a pragma No_Return is given.
3249 -- Normalized_First_Bit (Uint8)
3250 -- Defined in components and discriminants. Indicates the normalized
3251 -- value of First_Bit for the component, i.e. the offset within the
3252 -- lowest addressed storage unit containing part or all of the field.
3253 -- Set to No_Uint if no first bit position is assigned yet.
3255 -- Normalized_Position (Uint14)
3256 -- Defined in components and discriminants. Indicates the normalized
3257 -- value of Position for the component, i.e. the offset in storage
3258 -- units from the start of the record to the lowest addressed storage
3259 -- unit containing part or all of the field.
3261 -- Normalized_Position_Max (Uint10)
3262 -- Defined in components and discriminants. For almost all cases, this
3263 -- is the same as Normalized_Position. The one exception is for the case
3264 -- of a discriminated record containing one or more arrays whose length
3265 -- depends on discriminants. In this case, the Normalized_Position_Max
3266 -- field represents the maximum possible value of Normalized_Position
3267 -- assuming min/max values for discriminant subscripts in all fields.
3268 -- This is used by Layout in front end layout mode to properly computed
3269 -- the maximum size such records (needed for allocation purposes when
3270 -- there are default discriminants, and also for the 'Size value).
3272 -- No_Strict_Aliasing (Flag136) [base type only]
3273 -- Defined in access types. Set to direct the back end to avoid any
3274 -- optimizations based on an assumption about the aliasing status of
3275 -- objects designated by the access type. For the case of the gcc
3276 -- back end, the effect is as though all references to objects of
3277 -- the type were compiled with -fno-strict-aliasing. This flag is
3278 -- set if an unchecked conversion with the access type as a target
3279 -- type occurs in the same source unit as the declaration of the
3280 -- access type, or if an explicit pragma No_Strict_Aliasing applies.
3282 -- Number_Dimensions (synthesized)
3283 -- Applies to array types and subtypes. Returns the number of dimensions
3284 -- of the array type or subtype as a value of type Pos.
3286 -- Number_Entries (synthesized)
3287 -- Applies to concurrent types. Returns the number of entries that are
3288 -- declared within the task or protected definition for the type.
3290 -- Number_Formals (synthesized)
3291 -- Applies to subprograms and subprogram types. Yields the number of
3292 -- formals as a value of type Pos.
3294 -- OK_To_Rename (Flag247)
3295 -- Defined only in entities for variables. If this flag is set, it
3296 -- means that if the entity is used as the initial value of an object
3297 -- declaration, the object declaration can be safely converted into a
3298 -- renaming to avoid an extra copy. This is set for variables which are
3299 -- generated by the expander to hold the result of evaluating some
3300 -- expression. Most notably, the local variables used to store the result
3301 -- of concatenations are so marked (see Exp_Ch4.Expand_Concatenate). It
3302 -- is only worth setting this flag for composites, since for primitive
3303 -- types, it is cheaper to do the copy.
3305 -- OK_To_Reorder_Components (Flag239) [base type only]
3306 -- Defined in record types. Set if the back end is permitted to reorder
3307 -- the components. If not set, the record must be layed out in the order
3308 -- in which the components are declared textually. Currently this flag
3309 -- can only be set by debug switches.
3311 -- Optimize_Alignment_Space (Flag241)
3312 -- Defined in type, subtype, variable, and constant entities. This
3313 -- flag records that the type or object is to be layed out in a manner
3314 -- consistent with Optimize_Alignment (Space) mode. The compiler and
3315 -- binder ensure a consistent view of any given type or object. If pragma
3316 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3317 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3319 -- Optimize_Alignment_Time (Flag242)
3320 -- Defined in type, subtype, variable, and constant entities. This
3321 -- flag records that the type or object is to be layed out in a manner
3322 -- consistent with Optimize_Alignment (Time) mode. The compiler and
3323 -- binder ensure a consistent view of any given type or object. If pragma
3324 -- Optimize_Alignment (Off) mode applies to the type/object, then neither
3325 -- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
3327 -- Original_Access_Type (Node26)
3328 -- Defined in E_Access_Subprogram_Type entities. Set only if the access
3329 -- type was generated by the expander as part of processing an access
3330 -- to protected subprogram type. Points to the access to protected
3333 -- Original_Array_Type (Node21)
3334 -- Defined in modular types and array types and subtypes. Set only
3335 -- if the Is_Packed_Array_Type flag is set, indicating that the type
3336 -- is the implementation type for a packed array, and in this case it
3337 -- points to the original array type for which this is the packed
3338 -- array implementation type.
3340 -- Original_Record_Component (Node22)
3341 -- Defined in components, including discriminants. The usage depends
3342 -- on whether the record is a base type and whether it is tagged.
3344 -- In base tagged types:
3345 -- When the component is inherited in a record extension, it points
3346 -- to the original component (the entity of the ancestor component
3347 -- which is not itself inherited) otherwise it points to itself.
3348 -- Gigi uses this attribute to implement the automatic dereference in
3349 -- the extension and to apply the transformation:
3351 -- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
3353 -- In base non-tagged types:
3354 -- Always points to itself except for non-girder discriminants, where
3355 -- it points to the girder discriminant it renames.
3357 -- In subtypes (tagged and untagged):
3358 -- Points to the component in the base type.
3360 -- Overlays_Constant (Flag243)
3361 -- Defined in all entities. Set only for a variable for which there is
3362 -- an address clause which causes the variable to overlay a constant.
3364 -- Overridden_Operation (Node26)
3365 -- Defined in subprograms. For overriding operations, points to the
3366 -- user-defined parent subprogram that is being overridden. Note: this
3367 -- attribute uses the same field as Static_Initialization. The latter
3368 -- is only defined for internal initialization procedures, for which
3369 -- Overridden_Operation is irrelevant. Thus this attribute must not be
3370 -- set for init_procs.
3372 -- Package_Instantiation (Node26)
3373 -- Defined in packages and generic packages. When defined, this field
3374 -- references an N_Generic_Instantiation node associated with an
3375 -- instantiated package. In the case where the referenced node has
3376 -- been rewritten to an N_Package_Specification, the instantiation
3377 -- node is available from the Original_Node field of the package spec
3378 -- node. This is currently not guaranteed to be set in all cases, but
3379 -- when set, the field is used in Get_Package_Instantiation_Node as
3380 -- one of the means of obtaining the instantiation node. Eventually
3381 -- it should be set in all cases, including package entities associated
3382 -- with formal packages. ???
3384 -- Packed_Array_Type (Node23)
3385 -- Defined in array types and subtypes, including the string literal
3386 -- subtype case, if the corresponding type is packed (either bit packed
3387 -- or packed to eliminate holes in non-contiguous enumeration type index
3388 -- types). References the type used to represent the packed array, which
3389 -- is either a modular type for short static arrays, or an array of
3390 -- System.Unsigned. Note that in some situations (internal types, and
3391 -- references to fields of variant records), it is not always possible
3392 -- to construct this type in advance of its use. If Packed_Array_Type
3393 -- is empty, then the necessary type is declared on the fly for each
3394 -- reference to the array.
3396 -- Parameter_Mode (synthesized)
3397 -- Applies to formal parameter entities. This is a synonym for Ekind,
3398 -- used when obtaining the formal kind of a formal parameter (the result
3399 -- is one of E_[In/Out/In_Out]_Parameter)
3401 -- Parent_Subtype (Node19) [base type only]
3402 -- Defined in E_Record_Type. Set only for derived tagged types, in which
3403 -- case it points to the subtype of the parent type. This is the type
3404 -- that is used as the Etype of the _parent field.
3406 -- Postcondition_Proc (Node8)
3407 -- Defined only in procedure entities, saves the entity of the generated
3408 -- postcondition proc if one is present, otherwise is set to Empty. Used
3409 -- to generate the call to this procedure in case the expander inserts
3410 -- implicit return statements.
3412 -- PPC_Wrapper (Node25)
3413 -- Defined in entries and entry families. Set only if pre- or post-
3414 -- conditions are present. The precondition_wrapper body is the original
3415 -- entry call, decorated with the given precondition for the entry.
3417 -- Predicate_Function (synthesized)
3418 -- Defined in all types. Set for types for which (Has_Predicates is True)
3419 -- and for which a predicate procedure has been built that tests that the
3420 -- specified predicates are True. Contains the entity for the function
3421 -- which takes a single argument of the given type, and returns True if
3422 -- the predicate holds and False if it does not.
3424 -- Note: the reason this is marked as a synthesized attribute is that the
3425 -- way this is stored is as an element of the Subprograms_For_Type field.
3427 -- Predicate_Function_M (synthesized)
3428 -- Defined in all types. Present only if Predicate_Function is present,
3429 -- and only if the predicate function has Raise_Expression nodes. It
3430 -- is the special version created for membership tests, where if one of
3431 -- these raise expressions is executed, the result is to return False.
3433 -- Primitive_Operations (synthesized)
3434 -- Defined in concurrent types, tagged record types and subtypes, tagged
3435 -- private types and tagged incomplete types. For concurrent types whose
3436 -- Corresponding_Record_Type (CRT) is available, returns the list of
3437 -- Direct_Primitive_Operations of its CRT; otherwise returns No_Elist.
3438 -- For all the other types returns the Direct_Primitive_Operations.
3441 -- Defined in private components of protected types. Refers to the entity
3442 -- of the component renaming declaration generated inside protected
3443 -- subprograms, entries or barrier functions.
3445 -- Prival_Link (Node20)
3446 -- Defined in constants and variables which rename private components of
3447 -- protected types. Set to the original private component.
3449 -- Private_Dependents (Elist18)
3450 -- Defined in private (sub)types. Records the subtypes of the private
3451 -- type, derivations from it, and records and arrays with components
3452 -- dependent on the type.
3454 -- The subtypes are traversed when installing and deinstalling (the full
3455 -- view of) a private type in order to ensure correct view of the
3458 -- Used in similar fashion for incomplete types: holds list of subtypes
3459 -- of these incomplete types that have discriminant constraints. The
3460 -- full views of these subtypes are constructed when the full view of
3461 -- the incomplete type is processed.
3463 -- In addition, if the incomplete type is the designated type in an
3464 -- access definition for an access parameter, the operation may be
3465 -- a dispatching primitive operation, which is only known when the full
3466 -- declaration of the type is seen. Subprograms that have such an
3467 -- access parameter are also placed in the list of private_dependents.
3469 -- Private_View (Node22)
3470 -- For each private type, three entities are allocated, the private view,
3471 -- the full view, and the shadow entity. The shadow entity contains a
3472 -- copy of the private view and is used for restoring the proper private
3473 -- view after a region in which the full view is visible (and is copied
3474 -- into the entity normally used for the private view during this period
3475 -- of visibility). The Private_View field is self-referential when the
3476 -- private view lives in its normal entity, but in the copy that is made
3477 -- in the shadow entity, it points to the proper location in which to
3478 -- restore the private view saved in the shadow.
3480 -- Protected_Formal (Node22)
3481 -- Defined in formal parameters (in, in out and out parameters). Used
3482 -- only for formals of protected operations. References corresponding
3483 -- formal parameter in the unprotected version of the operation that
3484 -- is created during expansion.
3486 -- Protected_Body_Subprogram (Node11)
3487 -- Defined in protected operations. References the entity for the
3488 -- subprogram which implements the body of the operation.
3490 -- Protection_Object (Node23)
3491 -- Applies to protected entries, entry families and subprograms. Denotes
3492 -- the entity which is used to rename the _object component of protected
3495 -- Reachable (Flag49)
3496 -- Defined in labels. The flag is set over the range of statements in
3497 -- which a goto to that label is legal.
3499 -- Referenced (Flag156)
3500 -- Defined in all entities. Set if the entity is referenced, except for
3501 -- the case of an appearance of a simple variable that is not a renaming
3502 -- as the left side of an assignment in which case Referenced_As_LHS is
3503 -- set instead, or a similar appearance as an out parameter actual, in
3504 -- which case Referenced_As_Out_Parameter is set.
3506 -- Referenced_As_LHS (Flag36):
3507 -- Defined in all entities. This flag is set instead of Referenced if a
3508 -- simple variable that is not a renaming appears as the left side of an
3509 -- assignment. The reason we distinguish this kind of reference is that
3510 -- we have a separate warning for variables that are only assigned and
3513 -- Referenced_As_Out_Parameter (Flag227):
3514 -- Defined in all entities. This flag is set instead of Referenced if a
3515 -- simple variable that is not a renaming appears as an actual for an out
3516 -- formal. The reason we distinguish this kind of reference is that
3517 -- we have a separate warning for variables that are only assigned and
3518 -- never read, and out parameters are a special case.
3520 -- Refined_State (Node9)
3521 -- Defined in E_Abstract_State entities. Contains the entity of the
3522 -- abstract state completion which is usually foung in package bodies.
3524 -- Register_Exception_Call (Node20)
3525 -- Defined in exception entities. When an exception is declared,
3526 -- a call is expanded to Register_Exception. This field points to
3527 -- the expanded N_Procedure_Call_Statement node for this call. It
3528 -- is used for Import/Export_Exception processing to modify the
3529 -- register call to make appropriate entries in the special tables
3530 -- used for handling these pragmas at runtime.
3532 -- Related_Array_Object (Node25)
3533 -- Defined in array types and subtypes. Used only for the base type
3534 -- and subtype created for an anonymous array object. Set to point
3535 -- to the entity of the corresponding array object. Currently used
3536 -- only for type-related error messages.
3538 -- Related_Expression (Node24)
3539 -- Defined in variables and types. Set only for internally generated
3540 -- entities, where it may be used to denote the source expression whose
3541 -- elaboration created the variable declaration. If set, it is used
3542 -- for generating clearer messages from CodePeer.
3544 -- Shouldn't it also be used for the same purpose in errout? It seems
3545 -- odd to have two mechanisms here???
3547 -- Related_Instance (Node15)
3548 -- Defined in the wrapper packages created for subprogram instances.
3549 -- The internal subprogram that implements the instance is inside the
3550 -- wrapper package, but for debugging purposes its external symbol
3551 -- must correspond to the name and scope of the related instance.
3553 -- Related_Type (Node27)
3554 -- Defined in components, constants and variables. Set when there is an
3555 -- associated dispatch table to point to entities containing primary or
3556 -- secondary tags. Not set in the _tag component of record types.
3558 -- Relative_Deadline_Variable (Node26) [implementation base type only]
3559 -- Defined in task type entities. This flag is set if a valid and
3560 -- effective pragma Relative_Deadline applies to the base type. Points
3561 -- to the entity for a variable that is created to hold the value given
3562 -- in a Relative_Deadline pragma for a task type.
3564 -- Renamed_Entity (Node18)
3565 -- Defined in exceptions, packages, subprograms and generic units. Set
3566 -- for entities that are defined by a renaming declaration. Denotes the
3567 -- renamed entity, or transitively the ultimate renamed entity if
3568 -- there is a chain of renaming declarations. Empty if no renaming.
3570 -- Renamed_In_Spec (Flag231)
3572 -- Defined in package entities. If a package renaming occurs within
3573 -- a package spec, then this flag is set on the renamed package. The
3574 -- purpose is to prevent a warning about unused entities in the renamed
3575 -- package. Such a warning would be inappropriate since clients of the
3576 -- package can see the entities in the package via the renaming.
3578 -- Renamed_Object (Node18)
3579 -- Defined in all objects (constants, variables, components, formal
3580 -- parameters, generic formal parameters, and loop parameters).
3581 -- ??? Defined in discriminants?
3582 -- Set non-Empty if the object was declared by a renaming declaration,
3583 -- in which case it references the tree node for the name of the renamed
3584 -- object. This is only possible for the variable and constant cases.
3585 -- For formal parameters, this field is used in the course of inline
3586 -- expansion, to map the formals of a subprogram into the corresponding
3587 -- actuals. For formals of a task entry, it denotes the local renaming
3588 -- that replaces the actual within the accept statement. The field is
3589 -- Empty otherwise (it is always empty for loop parameters).
3591 -- Renaming_Map (Uint9)
3592 -- Defined in generic subprograms, generic packages, and their
3593 -- instances. Also defined in the instances of the corresponding
3594 -- bodies. Denotes the renaming map (generic entities => instance
3595 -- entities) used to construct the instance by givin an index into
3596 -- the tables used to represent these maps. See Sem_Ch12 for further
3597 -- details. The maps for package instances are also used when the
3598 -- instance is the actual corresponding to a formal package.
3600 -- Requires_Overriding (Flag213)
3601 -- Defined in all subprograms and entries. Set for subprograms that
3602 -- require overriding as defined by RM-2005-3.9.3(6/2). Note that this
3603 -- is True only for implicitly declare subprograms; it is not set on the
3604 -- parent type's subprogram. See also Is_Abstract_Subprogram.
3606 -- Return_Present (Flag54)
3607 -- Defined in function and generic function entities. Set if the
3608 -- function contains a return statement (used for error checking).
3609 -- This flag can also be set in procedure and generic procedure
3610 -- entities (for convenience in setting it), but is only tested
3611 -- for the function case.
3613 -- Return_Applies_To (Node8)
3614 -- Defined in E_Return_Statement. Points to the entity representing
3615 -- the construct to which the return statement applies, as defined in
3616 -- RM-6.5(4/2). Note that a (simple) return statement within an
3617 -- extended_return_statement applies to the extended_return_statement,
3618 -- even though it causes the whole function to return.
3620 -- Returns_By_Ref (Flag90)
3621 -- Defined in function entities, to indicate that the function
3622 -- returns the result by reference, either because its return type is a
3623 -- by-reference-type or because it uses explicitly the secondary stack.
3625 -- Reverse_Bit_Order (Flag164) [base type only]
3626 -- Defined in all record type entities. Set if entity has a Bit_Order
3627 -- aspect (set by an aspect clause or attribute definition clause) that
3628 -- has reversed the order of bits from the default value. When this flag
3629 -- is set, a component clause must specify a set of bits entirely within
3630 -- a single storage unit (Ada 95) or within a single machine scalar (see
3631 -- Ada 2005 AI-133), or must occupy an integral number of storage units.
3633 -- Reverse_Storage_Order (Flag93) [base type only]
3634 -- Defined in all record and array type entities. Set if entity has a
3635 -- Scalar_Storage_Order aspect (set by an aspect clause or attribute
3636 -- definition clause) that has reversed the order of storage elements
3637 -- from the default value. When this flag is set for a record type,
3638 -- the Bit_Order aspect must be set to the same value (either explicitly
3639 -- or as the target default value).
3642 -- Defined in all type and subtype entities. Contains the value of
3643 -- type'Size as defined in the RM. See also the Esize field and
3644 -- and the description on "Handling of Type'Size Values". A value
3645 -- of zero in this field for a non-discrete type means that
3646 -- the front end has not yet determined the size value. For the
3647 -- case of a discrete type, this field is always set by the front
3648 -- end and zero is a legitimate value for a type with one value.
3650 -- Root_Type (synthesized)
3651 -- Applies to all type entities. For class-wide types, return the root
3652 -- type of the class covered by the CW type, otherwise returns the
3653 -- ultimate derivation ancestor of the given type. This function
3654 -- preserves the view, i.e. the Root_Type of a partial view is the
3655 -- partial view of the ultimate ancestor, the Root_Type of a full view
3656 -- is the full view of the ultimate ancestor. Note that this function
3657 -- does not correspond exactly to the use of root type in the RM, since
3658 -- in the RM root type applies to a class of types, not to a type.
3660 -- Scalar_Range (Node20)
3661 -- Defined in all scalar types (including modular types, where the
3662 -- bounds are 0 .. modulus - 1). References a node in the tree that
3663 -- contains the bounds for the range. Note that this information
3664 -- could be obtained by rummaging around the tree, but it is more
3665 -- convenient to have it immediately at hand in the entity. The
3666 -- contents of Scalar_Range can either be an N_Subtype_Indication
3667 -- node (with a constraint), or a Range node, but not a simple
3668 -- subtype reference (a subtype is converted into a range).
3670 -- Scale_Value (Uint15)
3671 -- Defined in decimal fixed-point types and subtypes. Contains the scale
3672 -- for the type (i.e. the value of type'Scale = the number of decimal
3673 -- digits after the decimal point).
3676 -- Defined in all entities. Points to the entity for the scope (block,
3677 -- loop, subprogram, package etc.) in which the entity is declared.
3678 -- Since this field is in the base part of the entity node, the access
3679 -- routines for this field are in Sinfo. Note that for a child package,
3680 -- the Scope will be the parent package, and for a non-child package,
3681 -- the Scope will be Standard.
3683 -- Scope_Depth (synthesized)
3684 -- Applies to program units, blocks, concurrent types and entries, and
3685 -- also to record types, i.e. to any entity that can appear on the scope
3686 -- stack. Yields the scope depth value, which for those entities other
3687 -- than records is simply the scope depth value, for record entities, it
3688 -- is the Scope_Depth of the record scope.
3690 -- Scope_Depth_Value (Uint22)
3691 -- Defined in program units, blocks, concurrent types, and entries.
3692 -- Indicates the number of scopes that statically enclose the declaration
3693 -- of the unit or type. Library units have a depth of zero. Note that
3694 -- record types can act as scopes but do NOT have this field set (see
3695 -- Scope_Depth above)
3697 -- Scope_Depth_Set (synthesized)
3698 -- Applies to a special predicate function that returns a Boolean value
3699 -- indicating whether or not the Scope_Depth field has been set. It is
3700 -- needed, since returns an invalid value in this case!
3702 -- Sec_Stack_Needed_For_Return (Flag167)
3703 -- Defined in scope entities (blocks, functions, procedures, tasks,
3704 -- entries). Set to True when secondary stack is used to hold the
3705 -- returned value of a function and thus should not be released on
3708 -- Shadow_Entities (List14)
3709 -- Defined in package and generic package entities. Points to a list
3710 -- of entities that correspond to private types. For each private type
3711 -- a shadow entity is created that holds a copy of the private view.
3712 -- In regions of the program where the full views of these private
3713 -- entities are visible, the full view is copied into the entity that
3714 -- is normally used to hold the private view, but the shadow entity
3715 -- copy is unchanged. The shadow entities are then used to restore the
3716 -- original private views at the end of the region. This list is a
3717 -- standard format list (i.e. First (Shadow_Entities) is the first
3718 -- entry and subsequent entries are obtained using Next.
3720 -- Shared_Var_Procs_Instance (Node22)
3721 -- Defined in variables. Set non-Empty only if Is_Shared_Passive is
3722 -- set, in which case this is the entity for the associated instance of
3723 -- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details.
3725 -- Size_Check_Code (Node19)
3726 -- Defined in constants and variables. Normally Empty. Set if code is
3727 -- generated to check the size of the object. This field is used to
3728 -- suppress this code if a subsequent address clause is encountered.
3730 -- Size_Clause (synthesized)
3731 -- Applies to all entities. If a size clause is present in the rep
3732 -- item chain for an entity then the attribute definition clause node
3733 -- for the size clause is returned. Otherwise Size_Clause returns Empty
3734 -- if no item is present. Usually this is only meaningful if the flag
3735 -- Has_Size_Clause is set. This is because when the representation item
3736 -- chain is copied for a derived type, it can inherit a size clause that
3737 -- is not applicable to the entity.
3739 -- Size_Depends_On_Discriminant (Flag177)
3740 -- Defined in all entities for types and subtypes. Indicates that the
3741 -- size of the type depends on the value of one or more discriminants.
3742 -- Currently, this flag is only set for arrays which have one or more
3743 -- bounds depending on a discriminant value.
3745 -- Size_Known_At_Compile_Time (Flag92)
3746 -- Defined in all entities for types and subtypes. Indicates that the
3747 -- size of objects of the type is known at compile time. This flag is
3748 -- used to optimize some generated code sequences, and also to enable
3749 -- some error checks (e.g. disallowing component clauses on variable
3750 -- length objects). It is set conservatively (i.e. if it is True, the
3751 -- size is certainly known at compile time, if it is False, then the
3752 -- size may or may not be known at compile time, but the code will
3753 -- assume that it is not known).
3755 -- Small_Value (Ureal21)
3756 -- Defined in fixed point types. Points to the universal real for the
3757 -- Small of the type, either as given in a representation clause, or
3758 -- as computed (as a power of two) by the compiler.
3760 -- Spec_Entity (Node19)
3761 -- Defined in package body entities. Points to corresponding package
3762 -- spec entity. Also defined in subprogram body parameters in the
3763 -- case where there is a separate spec, where this field references
3764 -- the corresponding parameter entities in the spec.
3766 -- Static_Predicate (List25)
3767 -- Defined in discrete types/subtypes with predicates (Has_Predicates
3768 -- set True). Set if the type/subtype has a static predicate. Points to
3769 -- a list of expression and N_Range nodes that represent the predicate
3770 -- in canonical form. The canonical form has entries sorted in ascending
3771 -- order, with duplicates eliminated, and adjacent ranges coalesced, so
3772 -- that there is always a gap in the values between successive entries.
3773 -- The entries in this list are fully analyzed and typed with the base
3774 -- type of the subtype. Note that all entries are static and have values
3775 -- within the subtype range.
3777 -- Status_Flag_Or_Transient_Decl (Node15)
3778 -- Defined in variables and constants. Applies to objects that require
3779 -- special treatment by the finalization machinery, such as extended
3780 -- return results, IF and CASE expression results, and objects inside
3781 -- N_Expression_With_Actions nodes. The attribute contains the entity
3782 -- of a flag which specifies particular behavior over a region of code
3783 -- or the declaration of a "hook" object.
3784 -- In which case is it a flag, or a hook object???
3786 -- Storage_Size_Variable (Node15) [implementation base type only]
3787 -- Defined in access types and task type entities. This flag is set
3788 -- if a valid and effective pragma Storage_Size applies to the base
3789 -- type. Points to the entity for a variable that is created to
3790 -- hold the value given in a Storage_Size pragma for an access
3791 -- collection or a task type. Note that in the access type case,
3792 -- this field is defined only in the root type (since derived types
3793 -- share the same storage pool).
3795 -- Static_Elaboration_Desired (Flag77)
3796 -- Defined in library-level packages. Set by the pragma of the same
3797 -- name, to indicate that static initialization must be attempted for
3798 -- all types declared in the package, and that a warning must be emitted
3799 -- for those types to which static initialization is not available.
3801 -- Static_Initialization (Node30)
3802 -- Defined in initialization procedures for types whose objects can be
3803 -- initialized statically. The value of this attribute is a positional
3804 -- aggregate whose components are compile-time static values. Used
3805 -- when available in object declarations to eliminate the call to the
3806 -- initialization procedure, and to minimize elaboration code. Note:
3807 -- This attribute uses the same field as Overridden_Operation, which is
3808 -- irrelevant in init_procs.
3810 -- Stored_Constraint (Elist23)
3811 -- Defined in entities that can have discriminants (concurrent types
3812 -- subtypes, record types and subtypes, private types and subtypes,
3813 -- limited private types and subtypes and incomplete types). Points
3814 -- to an element list containing the expressions for each of the
3815 -- stored discriminants for the record (sub)type.
3817 -- Strict_Alignment (Flag145) [implementation base type only]
3818 -- Defined in all type entities. Indicates that some containing part
3819 -- is either aliased or tagged. This prohibits packing the object
3820 -- tighter than its natural size and alignment.
3822 -- String_Literal_Length (Uint16)
3823 -- Defined in string literal subtypes (which are created to correspond
3824 -- to string literals in the program). Contains the length of the string
3827 -- String_Literal_Low_Bound (Node15)
3828 -- Defined in string literal subtypes (which are created to correspond
3829 -- to string literals in the program). Contains an expression whose
3830 -- value represents the low bound of the literal. This is a copy of
3831 -- the low bound of the applicable index constraint if there is one,
3832 -- or a copy of the low bound of the index base type if not.
3834 -- Subprograms_For_Type (Node29)
3835 -- Defined in all type entities, and in subprogram entities. This is used
3836 -- to hold a list of subprogram entities for subprograms associated with
3837 -- the type, linked through the Subprogram_List field of the subprogram
3838 -- entity. Basically this is a way of multiplexing the single field to
3839 -- hold more than one entity (since we ran out of space in some type
3840 -- entities). This is currently used for Invariant_Procedure and also
3841 -- for Predicate_Function, and clients will always use the latter two
3842 -- names to access entries in this list.
3844 -- Suppress_Elaboration_Warnings (Flag148)
3845 -- Defined in all entities, can be set only for subprogram entities and
3846 -- for variables. If this flag is set then Sem_Elab will not generate
3847 -- elaboration warnings for the subprogram or variable. Suppression of
3848 -- such warnings is automatic for subprograms for which elaboration
3849 -- checks are suppressed (without the need to set this flag), but the
3850 -- flag is also set for various internal entities (such as init procs)
3851 -- which are known not to generate any possible access before
3852 -- elaboration, and it is set on variables when a warning is given to
3853 -- avoid multiple elaboration warnings for the same variable.
3855 -- Suppress_Initialization (Flag105)
3856 -- Defined in all type and subtype entities. If set for the base type,
3857 -- then the generation of initialization procedures is suppressed for the
3858 -- type. Any other implicit initialiation (e.g. from the use of pragma
3859 -- Initialize_Scalars) is also suppressed if this flag is set either for
3860 -- the subtype in question, or for the base type. Set by use of pragma
3861 -- Suppress_Initialization and also for internal entities where we know
3862 -- that no initialization is required. For example, enumeration image
3863 -- table entities set it.
3865 -- Suppress_Style_Checks (Flag165)
3866 -- Defined in all entities. Suppresses any style checks specifically
3867 -- associated with the given entity if set.
3869 -- Suppress_Value_Tracking_On_Call (Flag217)
3870 -- Defined in all entities. Set in a scope entity if value tracking is to
3871 -- be suppressed on any call within the scope. Used when an access to a
3872 -- local subprogram is computed, to deal with the possibility that this
3873 -- value may be passed around, and if used, may clobber a local variable.
3875 -- Task_Body_Procedure (Node25)
3876 -- Defined in task types and subtypes. Points to the entity for the task
3877 -- task body procedure (as further described in Exp_Ch9, task bodies are
3878 -- expanded into procedures). A convenient function to retrieve this
3879 -- field is Sem_Util.Get_Task_Body_Procedure.
3881 -- The last sentence is odd??? Why not have Task_Body_Procedure go to the
3882 -- Underlying_Type of the Root_Type???
3884 -- Thunk_Entity (Node31)
3885 -- Defined in functions and procedures which have been classified as
3886 -- Is_Thunk. Set to the target entity called by the thunk.
3888 -- Treat_As_Volatile (Flag41)
3889 -- Defined in all type entities, and also in constants, components and
3890 -- variables. Set if this entity is to be treated as volatile for code
3891 -- generation purposes. Always set if Is_Volatile is set, but can also
3892 -- be set as a result of situations (such as address overlays) where
3893 -- the front end wishes to force volatile handling to inhibit aliasing
3894 -- optimization which might be legally ok, but is undesirable. Note
3895 -- that the back end always tests this flag rather than Is_Volatile.
3896 -- The front end tests Is_Volatile if it is concerned with legality
3897 -- checks associated with declared volatile variables, but if the test
3898 -- is for the purposes of suppressing optimizations, then the front
3899 -- end should test Treat_As_Volatile rather than Is_Volatile.
3901 -- Note: before testing Treat_As_Volatile, consider whether it would
3902 -- be more appropriate to use Exp_Util.Is_Volatile_Reference instead,
3903 -- which catches more cases of volatile references.
3905 -- Type_High_Bound (synthesized)
3906 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
3907 -- the high bound of a scalar type. The returned value is literal for a
3908 -- base type, but may be an expression in the case of scalar type with
3909 -- dynamic bounds. Note that in the case of a fixed point type, the high
3910 -- bound is in units of small, and is an integer.
3912 -- Type_Low_Bound (synthesized)
3913 -- Applies to scalar types. Returns the tree node (Node_Id) that contains
3914 -- the low bound of a scalar type. The returned value is literal for a
3915 -- base type, but may be an expression in the case of scalar type with
3916 -- dynamic bounds. Note that in the case of a fixed point type, the low
3917 -- bound is in units of small, and is an integer.
3919 -- Underlying_Full_View (Node19)
3920 -- Defined in private subtypes that are the completion of other private
3921 -- types, or in private types that are derived from private subtypes. If
3922 -- the full view of a private type T is derived from another private type
3923 -- with discriminants Td, the full view of T is also private, and there
3924 -- is no way to attach to it a further full view that would convey the
3925 -- structure of T to the back end. The Underlying_Full_ View is an
3926 -- attribute of the full view that is a subtype of Td with the same
3927 -- constraint as the declaration for T. The declaration for this subtype
3928 -- is built at the point of the declaration of T, either as completion,
3929 -- or as a subtype declaration where the base type is private and has a
3930 -- private completion. If Td is already constrained, then its full view
3931 -- can serve directly as the full view of T.
3933 -- Underlying_Record_View (Node28)
3934 -- Defined in record types. Set for record types that are extensions of
3935 -- types with unknown discriminants, and also set for internally built
3936 -- underlying record views to reference its original record type. Record
3937 -- types that are extensions of types with unknown discriminants do not
3938 -- have a completion, but they cannot be used without having some
3939 -- discriminated view at hand. This view is a record type with the same
3940 -- structure, whose parent type is the full view of the parent in the
3941 -- original type extension.
3943 -- Underlying_Type (synthesized)
3944 -- Applies to all entities. This is the identity function except in the
3945 -- case where it is applied to an incomplete or private type, in which
3946 -- case it is the underlying type of the type declared by the completion,
3947 -- or Empty if the completion has not yet been encountered and analyzed.
3949 -- Note: the reason this attribute applies to all entities, and not just
3950 -- types, is to legitimize code where Underlying_Type is applied to an
3951 -- entity which may or may not be a type, with the intent that if it is a
3952 -- type, its underlying type is taken.
3954 -- Universal_Aliasing (Flag216) [implementation base type only]
3955 -- Defined in all type entities. Set to direct the back-end to avoid
3956 -- any optimizations based on type-based alias analysis for this type.
3957 -- Indicates that objects of this type can alias objects of any other
3958 -- types, which guarantees that any objects can be referenced through
3959 -- access types designating this type safely, whatever the actual type
3960 -- of these objects. In other words, the effect is as though access
3961 -- types designating this type were subject to No_Strict_Aliasing.
3963 -- Unset_Reference (Node16)
3964 -- Defined in variables and out parameters. This is normally Empty. It
3965 -- is set to point to an identifier that represents a reference to the
3966 -- entity before any value has been set. Only the first such reference
3967 -- is identified. This field is used to generate a warning message if
3968 -- necessary (see Sem_Warn.Check_Unset_Reference).
3970 -- Used_As_Generic_Actual (Flag222)
3971 -- Defined in all entities, set if the entity is used as an argument to
3972 -- a generic instantiation. Used to tune certain warning messages.
3974 -- Uses_Lock_Free (Flag188)
3975 -- Defined in protected type entities. Set to True when the Lock Free
3976 -- implementation is used for the protected type. This implemenatation is
3977 -- based on atomic transactions and doesn't require anymore the use of
3978 -- Protection object (see System.Tasking.Protected_Objects).
3980 -- Uses_Sec_Stack (Flag95)
3981 -- Defined in scope entities (blocks,functions, procedures, tasks,
3982 -- entries). Set to True when secondary stack is used in this scope and
3983 -- must be released on exit unless Sec_Stack_Needed_For_Return is set.
3985 -- Warnings_Off (Flag96)
3986 -- Defined in all entities. Set if a pragma Warnings (Off, entity-name)
3987 -- is used to suppress warnings for a given entity. It is also used by
3988 -- the compiler in some situations to kill spurious warnings. Note that
3989 -- clients should generally not test this flag directly, but instead
3990 -- use function Has_Warnings_Off.
3992 -- Warnings_Off_Used (Flag236)
3993 -- Defined in all entities. Can only be set if Warnings_Off is set. If
3994 -- set indicates that a warning was suppressed by the Warnings_Off flag,
3995 -- and Unmodified/Unreferenced would not have suppressed the warning.
3997 -- Warnings_Off_Used_Unmodified (Flag237)
3998 -- Defined in all entities. Can only be set if Warnings_Off is set and
3999 -- Has_Pragma_Unmodified is not set. If set indicates that a warning was
4000 -- suppressed by the Warnings_Off status but that pragma Unmodified
4001 -- would also have suppressed the warning.
4003 -- Warnings_Off_Used_Unreferenced (Flag238)
4004 -- Defined in all entities. Can only be set if Warnings_Off is set and
4005 -- Has_Pragma_Unreferenced is not set. If set indicates that a warning
4006 -- was suppressed by the Warnings_Off status but that pragma Unreferenced
4007 -- would also have suppressed the warning.
4009 -- Was_Hidden (Flag196)
4010 -- Defined in all entities. Used to save the value of the Is_Hidden
4011 -- attribute when the limited-view is installed (Ada 2005: AI-217).
4013 -- Wrapped_Entity (Node27)
4014 -- Defined in functions and procedures which have been classified as
4015 -- Is_Primitive_Wrapper. Set to the entity being wrapper.
4017 --------------------------------------
4018 -- Delayed Freezing and Elaboration --
4019 --------------------------------------
4021 -- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
4022 -- freeze node, which appears later in the expanded tree.
4024 -- a) The flag is used by the front-end to trigger expansion actions
4025 -- which include the generation of that freeze node. Typically this happens at
4026 -- the end of the current compilation unit, or before the first subprogram
4027 -- body is encountered in the current unit. See files freeze and exp_ch13 for
4028 -- details on the actions triggered by a freeze node, which include the
4029 -- construction of initialization procedures and dispatch tables.
4031 -- b) The flag is used by the backend to defer elaboration of the entity until
4032 -- its freeze node is seen. In the absence of an explicit freeze node, an
4033 -- entity is frozen (and elaborated) at the point of declaration.
4035 -- For object declarations, the flag is set when an address clause for the
4036 -- object is encountered. Legality checks on the address expression only
4037 -- take place at the freeze point of the object.
4039 -- Most types have an explicit freeze node, because they cannot be elaborated
4040 -- until all representation and operational items that apply to them have been
4041 -- analyzed. Private types and incomplete types have the flag set as well, as
4042 -- do task and protected types.
4044 -- Implicit base types created for type derivations, as well as classwide
4045 -- types created for all tagged types, have the flag set.
4047 -- If a subprogram has an access parameter whose designated type is incomplete
4048 -- the subprogram has the flag set.
4054 -- The following entity kinds are introduced by the corresponding type
4058 -- E_General_Access_Type,
4059 -- E_Access_Subprogram_Type,
4060 -- E_Anonymous_Access_Subprogram_Type,
4061 -- E_Access_Protected_Subprogram_Type,
4062 -- E_Anonymous_Access_Protected_Subprogram_Type
4063 -- E_Anonymous_Access_Type.
4065 -- E_Access_Subtype is for an access subtype created by a subtype
4068 -- In addition, we define the kind E_Allocator_Type to label allocators.
4069 -- This is because special resolution rules apply to this construct.
4070 -- Eventually the constructs are labeled with the access type imposed by
4071 -- the context. Gigi should never see the type E_Allocator.
4073 -- Similarly, the type E_Access_Attribute_Type is used as the initial kind
4074 -- associated with an access attribute. After resolution a specific access
4075 -- type will be established as determined by the context.
4077 -- Finally, the type Any_Access is used to label -null- during type
4078 -- resolution. Any_Access is also replaced by the context type after
4081 --------------------------------
4082 -- Classification of Entities --
4083 --------------------------------
4085 -- The classification of program entities which follows is a refinement of
4086 -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
4087 -- different type classes. Ada 95 entities include class wide types,
4088 -- protected types, subprogram types, generalized access types, generic
4089 -- formal derived types and generic formal packages.
4091 -- The order chosen for these kinds allows us to classify related entities
4092 -- so that they are contiguous. As a result, they do not appear in the
4093 -- exact same order as their order of first appearance in the LRM (For
4094 -- example, private types are listed before packages). The contiguity
4095 -- allows us to define useful subtypes (see below) such as type entities,
4096 -- overloaded entities, etc.
4098 -- Each entity (explicitly or implicitly declared) has a kind, which is
4099 -- a value of the following type:
4101 type Entity_Kind is (
4104 -- The initial Ekind value for a newly created entity. Also used as the
4105 -- Ekind for Standard_Void_Type, a type entity in Standard used as a
4106 -- dummy type for the return type of a procedure (the reason we create
4107 -- this type is to share the circuits for performing overload resolution
4115 -- Components of a record declaration, private declarations of
4116 -- protected objects.
4119 -- Constants created by an object declaration with a constant keyword

4207 E_Ordinary_Fixed_Point_Subtype,
4208 -- Ordinary fixed point subtype, created by either an ordinary fixed
4209 -- point subtype or ordinary fixed point type declaration (in the

5924 -- Since E_Void is the initial Ekind value of an entity when it is first

5927 -- are many instances in which fields of an E_Void entity are set in the
5928 -- code prior to setting the Ekind field. This is not well documented or
5929 -- well controlled, and needs cleaning up later. Meanwhile, the access
5930 -- procedures in the body of Einfo permit many, but not all, attributes
5931 -- to be applied to an E_Void entity, precisely so that this kind of
5932 -- pre-setting of attributes works. This is really a hole in the dynamic
5933 -- type checking, since there is no assurance that the eventual Ekind

5939 -- Component_Alignment Control --
5940 ---------------------------------
5942 -- There are four types of alignment possible for array and record
5943 -- types, and a field in the type entities contains a value of the
5944 -- following type indicating which alignment choice applies. For full
5945 -- details of the meaning of these alignment types, see description
5946 -- of the Component_Alignment pragma
5948 type Component_Alignment_Kind is (
5949 Calign_Default, -- default alignment
5950 Calign_Component_Size, -- natural alignment for component size
5951 Calign_Component_Size_4, -- natural for size <= 4, 4 for size >= 4
5952 Calign_Storage_Unit); -- all components byte aligned
5954 -----------------------------------
5955 -- Floating Point Representation --
5956 -----------------------------------
5958 type Float_Rep_Kind is (
5959 IEEE_Binary, -- IEEE 754p conform binary format
5960 VAX_Native, -- VAX D, F, G or H format
5961 AAMP); -- AAMP format
5967 -- In addition to attributes that are stored as plain data, other
5968 -- attributes are procedural, and require some small amount of
5969 -- computation. Of course, from the point of view of a user of this
5970 -- package, the distinction is not visible (even the field information
5971 -- provided below should be disregarded, as it is subject to change
5972 -- without notice!). A number of attributes appear as lists: lists of
5973 -- formals, lists of actuals, of discriminants, etc. For these, pairs
5974 -- of functions are defined, which take the form:
5976 -- function First_Thing (E : Enclosing_Construct) return Thing;
5977 -- function Next_Thing (T : Thing) return Thing;
5979 -- The end of iteration is always signaled by a value of Empty, so that
5980 -- loops over these chains invariably have the form:
5984 -- This := First_Thing (E);
5986 -- while Present (This) loop
5987 -- Do_Something_With (This);
5989 -- This := Next_Thing (This);
5992 -----------------------------------
5993 -- Handling of Check Suppression --
5994 -----------------------------------
5996 -- There are three ways that checks can be suppressed:
5998 -- 1. At the command line level
5999 -- 2. At the scope level.
6000 -- 3. At the entity level.
6002 -- See spec of Sem in sem.ads for details of the data structures used
6003 -- to keep track of these various methods for suppressing checks.
6005 -------------------------------
6006 -- Handling of Discriminants --
6007 -------------------------------
6009 -- During semantic processing, discriminants are separate entities which
6010 -- reflect the semantic properties and allowed usage of discriminants in
6013 -- In the case of discriminants used as bounds, the references are handled
6014 -- directly, since special processing is needed in any case. However, there
6015 -- are two circumstances in which discriminants are referenced in a quite
6016 -- general manner, like any other variables:
6018 -- In initialization expressions for records. Note that the expressions
6019 -- used in Priority, Storage_Size, Task_Info and Relative_Deadline
6020 -- pragmas are effectively in this category, since these pragmas are
6021 -- converted to initialized record fields in the Corresponding_Record_
6024 -- In task and protected bodies, where the discriminant values may be
6025 -- referenced freely within these bodies. Discriminants can also appear
6026 -- in bounds of entry families and in defaults of operations.
6028 -- In both these cases, the discriminants must be treated essentially as
6029 -- objects. The following approach is used to simplify and minimize the
6030 -- special processing that is required.
6032 -- When a record type with discriminants is analyzed, semantic processing
6033 -- creates the entities for the discriminants. It also creates additional
6034 -- sets of entities called discriminals, one for each of the discriminants,
6035 -- and the Discriminal field of the discriminant entity points to this
6036 -- additional entity, which is initially created as an uninitialized
6039 -- During expansion of expressions, any discriminant reference is replaced
6040 -- by a reference to the corresponding discriminal. When the initialization
6041 -- procedure for the record is created (there will always be one, since
6042 -- discriminants are present, see Exp_Ch3 for further details), the
6043 -- discriminals are used as the entities for the formal parameters of
6044 -- this initialization procedure. The references to these discriminants
6045 -- have already been replaced by references to these discriminals, which
6046 -- are now the formal parameters corresponding to the required objects.
6048 -- In the case of a task or protected body, the semantics similarly creates
6049 -- a set of discriminals for the discriminants of the task or protected
6050 -- type. When the procedure is created for the task body, the parameter
6051 -- passed in is a reference to the task value type, which contains the
6052 -- required discriminant values. The expander creates a set of declarations
6055 -- discr_nameD : constant discr_type renames _task.discr_name;
6057 -- where discr_nameD is the discriminal entity referenced by the task
6058 -- discriminant, and _task is the task value passed in as the parameter.
6059 -- Again, any references to discriminants in the task body have been
6060 -- replaced by the discriminal reference, which is now an object that
6061 -- contains the required value.
6063 -- This approach for tasks means that two sets of discriminals are needed
6064 -- for a task type, one for the initialization procedure, and one for the
6065 -- task body. This works out nicely, since the semantics allocates one set
6066 -- for the task itself, and one set for the corresponding record.
6068 -- The one bit of trickiness arises in making sure that the right set of
6069 -- discriminals is used at the right time. First the task definition is
6070 -- processed. Any references to discriminants here are replaced by the
6071 -- corresponding *task* discriminals (the record type doesn't even exist
6072 -- yet, since it is constructed as part of the expansion of the task
6073 -- declaration, which happens after the semantic processing of the task
6074 -- definition). The discriminants to be used for the corresponding record
6075 -- are created at the same time as the other discriminals, and held in the
6076 -- CR_Discriminant field of the discriminant. A use of the discriminant in
6077 -- a bound for an entry family is replaced with the CR_Discriminant because
6078 -- it controls the bound of the entry queue array which is a component of
6079 -- the corresponding record.
6081 -- Just before the record initialization routine is constructed, the
6082 -- expander exchanges the task and record discriminals. This has two
6083 -- effects. First the generation of the record initialization routine
6084 -- uses the discriminals that are now on the record, which is the set
6085 -- that used to be on the task, which is what we want.
6087 -- Second, a new set of (so far unused) discriminals is now on the task
6088 -- discriminants, and it is this set that will be used for expanding the
6089 -- task body, and also for the discriminal declarations at the start of
6092 ---------------------------------------------------
6093 -- Handling of private data in protected objects --
6094 ---------------------------------------------------
6096 -- Private components in protected types pose problems similar to those
6097 -- of discriminants. Private data is visible and can be directly referenced
6098 -- from protected bodies. However, when protected entries and subprograms
6099 -- are expanded into corresponding bodies and barrier functions, private
6100 -- components lose their original context and visibility.
6102 -- To remedy this side effect of expansion, private components are expanded
6103 -- into renamings called "privals", by analogy with "discriminals".
6105 -- private_comp : comp_type renames _object.private_comp;
6107 -- Prival declarations are inserted during the analysis of subprogram and
6108 -- entry bodies to ensure proper visibility for any subsequent expansion.
6109 -- _Object is the formal parameter of the generated corresponding body or
6110 -- a local renaming which denotes the protected object obtained from entry
6111 -- parameter _O. Privals receive minimal decoration upon creation and are
6112 -- categorized as either E_Variable for the general case or E_Constant when
6113 -- they appear in functions.
6115 -- Along with the local declarations, each private component carries a
6116 -- placeholder which references the prival entity in the current body. This
6117 -- form of indirection is used to resolve name clashes of privals and other
6118 -- locally visible entities such as parameters, local objects, entry family
6119 -- indexes or identifiers used in the barrier condition.
6121 -- When analyzing the statements of a protected subprogram or entry, any
6122 -- reference to a private component must resolve to the locally declared
6123 -- prival through normal visibility. In case of name conflicts (the cases
6124 -- above), the prival is marked as hidden and acts as a weakly declared
6125 -- entity. As a result, the reference points to the correct entity. When a
6126 -- private component is denoted by an expanded name (prot_type.comp for
6127 -- example), the expansion mechanism uses the placeholder of the component
6128 -- to correct the Entity and Etype of the reference.
6134 -- The following type synonyms are used to tidy up the function and
6135 -- procedure declarations that follow, and also to make it possible to meet
6136 -- the requirement for the XEINFO utility that all function specs must fit
6137 -- on a single source line.

6703 ----------------------------------------------
6705 -- These predicates test the setting of the indicated attribute. If the
6706 -- value has been set, then Known is True, and Unknown is False. If no
6707 -- value is set, then Known is False and Unknown is True. The Known_Static
6708 -- predicate is true only if the value is set (Known) and is set to a
6709 -- compile time known value. Note that in the case of Alignment and
6710 -- Normalized_First_Bit, dynamic values are not possible, so we do not
6711 -- need a separate Known_Static calls in these cases. The not set (unknown)
6712 -- values are as follows:
6714 -- Alignment Uint_0 or No_Uint
6715 -- Component_Size Uint_0 or No_Uint
6716 -- Component_Bit_Offset No_Uint
6717 -- Digits_Value Uint_0 or No_Uint
6718 -- Esize Uint_0 or No_Uint
6719 -- Normalized_First_Bit No_Uint
6720 -- Normalized_Position No_Uint
6721 -- Normalized_Position_Max No_Uint
6722 -- RM_Size Uint_0 or No_Uint
6724 -- It would be cleaner to use No_Uint in all these cases, but historically
6725 -- we chose to use Uint_0 at first, and the change over will take time ???
6726 -- This is particularly true for the RM_Size field, where a value of zero
6727 -- is legitimate. We deal with this by a nasty kludge that knows that the
6728 -- value is always known static for discrete types (and no other types can
6729 -- have an RM_Size value of zero).
6731 -- In two cases, Known_Static_Esize and Known_Static_RM_Size, there is one
6732 -- more consideration, which is that we always return False for generic
6733 -- types. Within a template, the size can look known, because of the fake
6734 -- size values we put in template types, but they are not really known and
6735 -- anyone testing if they are known within the template should get False as
6736 -- a result to prevent incorrect assumptions.
