41 -- This package defines the annotations to the abstract syntax tree that
42 -- are needed to support semantic processing of an Ada compilation.
44 -- These annotations are for the most part attributes of declared entities,
45 -- and they correspond to conventional symbol table information. Other
46 -- attributes include sets of meanings for overloaded names, possible
47 -- types for overloaded expressions, flags to indicate deferred constants,
48 -- incomplete types, etc. These attributes are stored in available fields
49 -- in tree nodes (i.e. fields not used by the parser, as defined by the
50 -- Sinfo package specification), and accessed by means of a set of
51 -- subprograms which define an abstract interface.
53 -- There are two kinds of semantic information
55 -- First, the tree nodes with the following Nkind values:
57 -- N_Defining_Identifier
58 -- N_Defining_Character_Literal
59 -- N_Defining_Operator_Symbol
61 -- are called Entities, and constitute the information that would often
62 -- be stored separately in a symbol table. These nodes are all extended
63 -- to provide extra space, and contain fields which depend on the entity
64 -- kind, as defined by the contents of the Ekind field. The use of the
65 -- Ekind field, and the associated fields in the entity, are defined
66 -- in this package, as are the access functions to these fields.
68 -- Second, in some cases semantic information is stored directly in other
69 -- kinds of nodes, e.g. the Etype field, used to indicate the type of an
70 -- expression. The access functions to these fields are defined in the
71 -- Sinfo package, but their full documentation is to be found in
72 -- the Einfo package specification.
74 -- Declaration processing places information in the nodes of their defining
75 -- identifiers. Name resolution places in all other occurrences of an
76 -- identifier a pointer to the corresponding defining occurrence.
78 --------------------------------
79 -- The XEINFO Utility Program --
80 --------------------------------
82 -- XEINFO is a utility program which automatically produces a C header file,
83 -- a-xeinfo.h from the spec and body of package Einfo. It reads the input
84 -- files einfo.ads and einfo.adb and produces the output file a-xeinfo.h.
86 -- In order for this utility program to operate correctly, the form of the
87 -- einfo.ads and einfo.adb files must meet certain requirements and be laid
88 -- out in a specific manner.
90 -- The general form of einfo.ads is as follows:
92 -- type declaration for type Entity_Kind
93 -- subtype declarations declaring subranges of Entity_Kind
94 -- subtype declarations declaring synonyms for some standard types
95 -- function specs for attributes
97 -- pragma Inline declarations
99 -- This order must be observed. There are no restrictions on the procedures,
100 -- since the C header file only includes functions (Gigi is not allowed to
101 -- modify the generated tree). However, functions are required to have headers
102 -- that fit on a single line.
104 -- XEINFO reads and processes the function specs and the pragma Inlines. For
105 -- functions that are declared as inlined, XEINFO reads the corresponding body
106 -- from xeinfo.adb, and processes it into C code. This results in some strict
107 -- restrictions on which functions can be inlined:
109 -- The function spec must be on a single line
111 -- There can only be a single statement, contained on a single line,
112 -- not counting any pragma Assert statements.
114 -- This single statement must either by a function call with simple,
115 -- single token arguments, or it must be a membership test of the form
116 -- a in b, where a and b are single tokens.
118 -- For functions that are not inlined, there is no restriction on the body,
119 -- and XEINFO generates a direct reference in the C header file which allows
120 -- the C code in Gigi to directly call the corresponding Ada body.
122 ----------------------------------
123 -- Handling of Type'Size Values --
124 ----------------------------------
126 -- The Ada 95 RM contains some rather peculiar (to us!) rules on the value
127 -- of type'Size (see RM 13.3(55)). We have found that attempting to use
128 -- these RM Size values generally, and in particular for determining the
129 -- default size of objects, creates chaos, and major incompatibilies in
132 -- We proceed as follows, for discrete and fixed-point subtypes, we have
133 -- two separate sizes for each subtype:
135 -- The Object_Size, which is used for determining the default size of
136 -- objects and components. This size value can be referred to using the
137 -- Object_Size attribute. The phrase "is used" here means that it is
138 -- the basis of the determination of the size. The backend is free to
139 -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
140 -- character might be stored in 32 bits on a machine with no efficient
141 -- byte access instructions such as the Alpha.
143 -- The default rules for the value of Object_Size for fixed-point and
144 -- discrete types are as follows:
146 -- The Object_Size for base subtypes reflect the natural hardware
147 -- size in bits (see Ttypes and Cstand for integer types). For
148 -- enumeration and fixed-point base subtypes have 8. 16. 32 or 64
149 -- bits for this size, depending on the range of values to be stored.
151 -- The Object_Size of a subtype is the same as the Object_Size of
152 -- the subtype from which it is obtained.
154 -- The Object_Size of a derived base type is copied from the parent
155 -- base type, and the Object_Size of a derived first subtype is copied
156 -- from the parent first subtype.
158 -- The Value_Size which is the number of bits required to store a value
159 -- of the type. This size can be referred to using the Value_Size
160 -- attribute. This value is used to determine how tightly to pack
161 -- records or arrays with components of this type, and also affects
162 -- the semantics of unchecked conversion (unchecked conversions where
163 -- the Value_Size values differ generate a warning, and are potentially
164 -- target dependent).
166 -- The default rule for the value of Value_Size are as follows:
168 -- The Value_Size for a base subtype is the minimum number of bits
169 -- required to store all values of the type (including the sign bit
170 -- only if negative values are possible).
172 -- If a subtype statically matches the first subtype, then it has
173 -- by default the same Value_Size as the first subtype. This is a
174 -- consequence of RM 13.1(14) ("if two subtypes statically match,
175 -- then their subtype-specific aspects are the same".)
177 -- All other subtypes have a Value_Size corresponding to the minimum
178 -- number of bits required to store all values of the subtype. For
179 -- dynamic bounds, it is assumed that the value can range down or up
180 -- to the corresponding bound of the ancestor
182 -- The RM defined attribute Size corresponds to the Value_Size attribute.
184 -- The Size attribute may be defined for a first-named subtype. This sets
185 -- the Value_Size of the first-named subtype to the given value, and the
186 -- Object_Size of this first-named subtype to the given value padded up
187 -- to an appropriate boundary. It is a consequence of the default rules
188 -- above that this Object_Size will apply to all further subtypes. On the
189 -- otyher hand, Value_Size is affected only for the first subtype, any
190 -- dynamic subtypes obtained from it directly, and any statically matching
191 -- subtypes. The Value_Size of any other static subtypes is not affected.
193 -- Value_Size and Object_Size may be explicitly set for any subtype using
194 -- an attribute definition clause. Note that the use of these attributes
195 -- can cause the RM 13.1(14) rule to be violated. If two access types
196 -- reference aliased objects whose subtypes have differing Object_Size
197 -- values as a result of explicit attribute definition clauses, then it
198 -- is erroneous to convert from one access subtype to the other.
200 -- At the implementation level, Esize stores the Object_Size and the
201 -- RM_Size field stores the Value_Size (and hence the value of the
202 -- Size attribute, which, as noted above, is equivalent to Value_Size).
204 -- To get a feel for the difference, consider the following examples (note
205 -- that in each case the base is short_short_integer with a size of 8):
207 -- Object_Size Value_Size
209 -- type x1 is range 0..5; 8 3
211 -- type x2 is range 0..5;
212 -- for x2'size use 12; 12 12
214 -- subtype x3 is x2 range 0 .. 3; 12 2
216 -- subtype x4 is x2'base range 0 .. 10; 8 4
218 -- subtype x5 is x2 range 0 .. dynamic; 12 (7)
220 -- subtype x6 is x2'base range 0 .. dynamic; 8 (7)
222 -- Note: the entries marked (7) are not actually specified by the Ada 95 RM,
223 -- but it seems in the spirit of the RM rules to allocate the minimum number
224 -- of bits known to be large enough to hold the given range of values.
226 -- So far, so good, but GNAT has to obey the RM rules, so the question is
227 -- under what conditions must the RM Size be used. The following is a list
228 -- of the occasions on which the RM Size must be used:
230 -- Component size for packed arrays or records
231 -- Value of the attribute Size for a type
232 -- Warning about sizes not matching for unchecked conversion
234 -- The RM_Size field keeps track of the RM Size as needed in these
237 -- For types other than discrete and fixed-point types, the Object_Size
238 -- and Value_Size are the same (and equivalent to the RM attribute Size).
239 -- Only Size may be specified for such types.
241 -----------------------
242 -- Entity Attributes --
243 -----------------------
245 -- This section contains a complete list of the attributes that are defined
246 -- on entities. Some attributes apply to all entities, others only to certain
247 -- kinds of entities. In the latter case the attribute should only be set or
248 -- accessed if the Ekind field indicates an appropriate entity.
250 -- There are two kinds of attributes that apply to entities, stored and
251 -- synthesized. Stored attributes correspond to a field or flag in the entity
252 -- itself. Such attributes are identified in the table below by giving the
253 -- field or flag in the attribute that is used to hold the attribute value.
254 -- Synthesized attributes are not stored directly, but are rather computed as
255 -- needed from other attributes, or from information in the tree. These are
256 -- marked "synthesized" in the table below. The stored attributes have both
257 -- access functions and set procedures to set the corresponding values, while
258 -- synthesized attributes have only access functions.
260 -- Note: in the case of Node, Uint, or Elist fields, there are cases where
261 -- the same physical field is used for different purposes in different
262 -- entities, so these access functions should only be referenced for the
263 -- class of entities in which they are defined as being present. Flags are
264 -- not overlapped in this way, but nevertheless as a matter of style and
265 -- abstraction (which may or may not be checked by assertions in the body),
266 -- this restriction should be observed for flag fields as well.
268 -- Note: certain of the attributes on types apply only to base types, and
269 -- are so noted by the notation [base type only]. These are cases where the
270 -- attribute of any subtype is the same as the attribute of the base type.
271 -- The attribute can be referenced on a subtype (and automatically retrieves
272 -- the value from the base type). However, it is an error to try to set the
273 -- attribute on other than the base type, and if assertions are enabled,
274 -- an attempt to set the attribute on a subtype will raise an assert error.
276 -- Other attributes are noted as applying the implementation base type only.
277 -- These are representation attributes which must always apply to a full
278 -- non-private type, and where the attributes are always on the full type.
279 -- The attribute can be referenced on a subtype (and automatically retries
280 -- the value from the implementation base type). However, it is an error
281 -- to try to set the attribute on other than the implementation base type,
282 -- and if assertions are enabled, an attempt to set the attribute on a
283 -- subtype will raise an assert error.
285 -- Accept_Address (Elist21)
286 -- Present in entries. If an accept has a statement sequence, then an
287 -- address variable is created, which is used to hold the address of the
288 -- parameters, as passed by the runtime. Accept_Address holds an element
289 -- list which represents a stack of entities for these address variables.
290 -- The current entry is the top of the stack, which is the last element
291 -- on the list. A stack is required to handle the case of nested select
292 -- statements referencing the same entry.
294 -- Actual_Subtype (Node17)
295 -- Present in variables, constants, and formal parameters. This is the
296 -- subtype imposed by the value of the object, as opposed to its nominal
297 -- subtype, which is imposed by the declaration. The actual subtype
298 -- differs from the nominal one when the latter is indefinite (as in the
299 -- case of an unconstrained formal parameter, or a variable declared
300 -- with an unconstrained type and an initial value). The nominal subtype
301 -- is the Etype entry for the entity. The Actual_Subtype field is set
302 -- only if the actual subtype differs from the nominal subtype. If the
303 -- actual and nominal subtypes are the same, then the Actual_Subtype
304 -- field is Empty, and Etype indicates both types.
306 -- For objects, the Actual_Subtype is set only if this is a discriminated
307 -- type. For arrays, the bounds of the expression are obtained and the
308 -- Etype of the object is directly the constrained subtype. This is
309 -- rather irregular, and the semantic checks that depend on the nominal
310 -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
312 -- Access_Disp_Table (Node16) [implementation base type only]
313 -- Present in record type entities. For a tagged type, points to the
314 -- dispatch table associated with the tagged type. For a non-tagged
315 -- record, contains Empty.
317 -- Address_Clause (synthesized)
318 -- Applies to entries, objects and subprograms. Set if an address clause
319 -- is present which references the object or subprogram and points to
320 -- the N_Attribute_Definition_Clause node. Empty if no Address clause.
321 -- The expression in the address clause is always a constant that is
322 -- defined before the entity to which the address clause applies.
323 -- Note: Gigi references this field in E_Task_Type entities???
325 -- Address_Taken (Flag104)
326 -- Present in all entities. Set if the Address or Unrestricted_Access
327 -- attribute is applied directly to the entity, i.e. the entity is the
328 -- entity of the prefix of the attribute reference. Used by Gigi to
329 -- make sure that the address can be meaningfully taken.
332 -- Present in overloaded entities (literals, subprograms, entries).
333 -- Points to parent subprogram of a derived subprogram. Also used for
334 -- a subprogram renaming, where it points to the renamed subprogram.
335 -- Always empty for entries.
337 -- Alignment (Uint14)
338 -- Present in entities for types and also in constants, variables,
339 -- loop parameters, and formal parameters. This indicates the desired
340 -- alignment for a type, or the actual alignment for an object. A value
341 -- of zero (Uint_0) indicates that the alignment has not been set yet.
342 -- The alignment can be set by an explicit alignment clause, or set by
343 -- the front-end in package Layout, or set by the back-end as part of
344 -- the back end back-annotation process. The alignment field is also
345 -- present in E_Exception entities, but there it is used only by the
346 -- back-end for back annotation.
348 -- Alignment_Clause (synthesized)
349 -- Appllies to all entities for types and objects. If an alignment
350 -- attribute definition clause is present for the entity, then this
351 -- function returns the N_Attribute_Definition clause that specifies the
352 -- alignment. If no alignment clause applies to the type, then the call
353 -- to this function returns Empty. Note that the call can return a
354 -- non-Empty value even if Has_Alignment_Clause is not set (happens with
355 -- subtype and derived type declarations). Note also that a record
356 -- definition clause with an (obsolescent) mod clause is converted
357 -- into an attribute definition clause for this purpose.
359 -- Ancestor_Subtype (synthesized)
360 -- Applies to all type and subtype entities. If the argument is a
361 -- subtype then it returns the subtype or type from which the subtype
362 -- was obtained, otherwise it returns Empty.
364 -- Associated_Formal_Package (Node12)
365 -- Present in packages that are the actuals of formal_packages. Points
366 -- to the entity in the declaration for the formal package.
368 -- Associated_Node_For_Itype (Node8)
369 -- Present in all type and subtype entities. Set non-Empty only for
370 -- Itypes. Set to point to the associated node for the Itype, i.e.
371 -- the node whose elaboration generated the Itype. This is used for
372 -- copying trees, to determine whether or not to copy an Itype.
374 -- Associated_Storage_Pool (Node22) [root type only]
375 -- Present in simple and general access type entities. References the
376 -- storage pool to be used for the corresponding collection. A value of
377 -- Empty means that the default pool is to be used. This is present
378 -- only in the root type, since derived types must have the same pool
379 -- as the parent type.
381 -- Associated_Final_Chain (Node23)
382 -- Present in simple and general access type entities. References the
383 -- List_Controller object that holds the finalization chain on which
384 -- are attached dynamically allocated objects referenced by the access
385 -- type. Empty when the access type cannot reference a controlled object.
387 -- Barrier_Function (Node12)
388 -- Present in protected entries and entry families. This is the
389 -- subprogram declaration for the body of the function that returns
390 -- the value of the entry barrier.
392 -- Base_Type (synthesized)
393 -- Applies to all type entities. Returns the base type of a type or
394 -- subtype. The base type of a type is the type itself. The base type
395 -- of a subtype is the type that it constrains (which is always a type
396 -- entity, not some other subtype). Note that in the case of a subtype
397 -- of a private type, it is possible for the base type attribute to
398 -- return a private type, even if the subtype to which it applies is
399 -- non-private. See also Implementation_Base_Type. Note: it is allowed
400 -- to apply Base_Type to other than a type, in which case it simply
401 -- returns the entity unchanged.
403 -- Block_Node (Node11)
404 -- Present in block entities. Points to the identifier in the
405 -- Block_Statement itself. Used when retrieving the block construct
406 -- for finalization purposes, The block entity has an implicit label
407 -- declaration in the enclosing declarative part, and has otherwise
408 -- no direct connection in the tree with the block statement. The
409 -- link is to the identifier (which is an occurence of the entity)
410 -- and not to the block_statement itself, because the statement may
411 -- be rewritten, e.g. in the process of removing dead code.
413 -- Body_Entity (Node19)
414 -- Present in package and generic package entities, points to the
415 -- corresponding package body entity if one is present.
417 -- Body_Needed_For_SAL (Flag40)
418 -- Present in package and subprogram entities that are compilation
419 -- units. Indicates that the source for the body must be included
420 -- when the unit is part of a standalone library.
422 -- C_Pass_By_Copy (Flag125) [implementation base type only]
423 -- Present in record types. Set if a pragma Convention for the record
424 -- type specifies convention C_Pass_By_Copy. This convention name is
425 -- treated as identical in all respects to convention C, except that
426 -- if it is specified for a record type, then the C_Pass_By_Copy flag
427 -- is set, and if a foreign convention subprogram has a formal of the
428 -- corresponding type, then the parameter passing mechanism will be
429 -- set to By_Copy (unless specifically overridden by an Import or
432 -- Can_Never_Be_Null (Flag38)
433 -- This flag is present in all entities, but can only be set in an
434 -- object which can never have a null value. This is used to avoid
435 -- unncessary resetting of the Is_Known_Non_Null flag for such
436 -- entities. The cases where this is set True are constant access
437 -- values initialized to a non-null value, and access parameters.
440 -- Present in all entities. This field contains an entry into the names
441 -- table that has the character string of the identifier, character
442 -- literal or operator symbol. See Namet for further details. Note that
443 -- throughout the processing of the front end, this name is the simple
444 -- unqualified name. However, just before gigi is called, a call is made
445 -- to Qualify_All_Entity_Names. This causes entity names to be qualified
446 -- using the encoding described in exp_dbug.ads, and from that point on
447 -- (including post gigi steps such as cross-reference generation), the
448 -- entities will contain the encoded qualified names.
450 -- Checks_May_Be_Suppressed (Flag31)
451 -- Present in all entities. Set if a pragma Suppress or Unsuppress
452 -- mentions the entity specifically in the second argument. If this
453 -- flag is set the the Global_Entity_Suppress and Local_Entity_Suppress
454 -- tables must be consulted to determine if the is actually an active
455 -- Suppress or Unsuppress pragma that applies to the entity.
457 -- Class_Wide_Type (Node9)
458 -- Present in all type entities. For a tagged type or subtype, returns
459 -- the corresponding implicitly declared class-wide type. Set to Empty
460 -- for non-tagged types.
462 -- Cloned_Subtype (Node16)
463 -- Present in E_Record_Subtype and E_Class_Wide_Subtype entities.
464 -- Each such entity can either have a Discriminant_Constraint, in
465 -- which case it represents a distinct type from the base type (and
466 -- will have a list of components and discrimants in the list headed by
467 -- First_Entity) or else no such constraint, in which case it will be a
468 -- copy of the base type.
470 -- o Each element of the list in First_Entity is copied from the base
471 -- type; in that case, this field is Empty.
473 -- o The list in First_Entity is shared with the base type; in that
474 -- case, this field points to that entity.
476 -- A record or classwide subtype may also be a copy of some other
477 -- subtype and share the entities in the First_Entity with that subtype.
478 -- In that case, this field points to that subtype.
480 -- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
481 -- this field. Note that this field ONLY appears in subtype entries, not
482 -- in type entries, it is not present, and it is an error to reference
483 -- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
486 -- This flag appears on all nodes, including entities, and indicates
487 -- that the node was created by the scanner or parser from the original
488 -- source. Thus for entities, it indicates that the entity is defined
489 -- in the original source program.
491 -- Component_Alignment (special field) [base type only]
492 -- Present in array and record entities. Contains a value of type
493 -- Component_Alignment_Kind indicating the alignment of components.
494 -- Set to Calign_Default normally, but can be overridden by use of
495 -- the Component_Alignment pragma. Note: this field is currently
496 -- stored in a non-standard way, see body for details.
498 -- Component_Bit_Offset (Uint11)
499 -- Present in record components (E_Component, E_Discriminant) if a
500 -- component clause applies to the component. First bit position of
501 -- given component, computed from the first bit and position values
502 -- given in the component clause. A value of No_Uint means that the
503 -- value is not yet known. The value can be set by the appearence of
504 -- an explicit component clause in a record representation clause,
505 -- or it can be set by the front-end in package Layout, or it can be
506 -- set by the backend. By the time backend processing is completed,
507 -- this field is always set. A negative value is used to represent
508 -- a value which is not known at compile time, and must be computed
509 -- at run-time (this happens if fields of a record have variable
510 -- lengths). See package Layout for details of these values.
512 -- Note: this field is obsolescent, to be eventually replaced entirely
513 -- by Normalized_First_Bit and Normalized_Position, but for the moment,
514 -- gigi is still using (and back annotating) this field, and gigi does
515 -- not know about the new fields. For the front end layout case, the
516 -- Component_Bit_Offset field is only set if it is static, and otherwise
517 -- the new Normalized_First_Bit and Normalized_Position fields are used.
519 -- Component_Clause (Node13)
520 -- Present in record components and discriminants. If a record
521 -- representation clause is present for the corresponding record
522 -- type a that specifies a position for the component, then the
523 -- Component_Clause field of the E_Component entity points to the
524 -- N_Component_Clause node. Set to Empty if no record representation
525 -- clause was present, or if there was no specification for this
528 -- Component_Size (Uint22) [implementation base type only]
529 -- Present in array types. It contains the component size value for
530 -- the array. A value of zero means that the value is not yet set.
531 -- The value can be set by the use of a component size clause, or
532 -- by the front end in package Layout, or by the backend. A negative
533 -- value is used to represent a value which is not known at compile
534 -- time, and must be computed at run-time (this happens if the type
535 -- of the component has a variable length size). See package Layout
536 -- for details of these values.
538 -- Component_Type (Node20) [implementation base type only]
539 -- Present in array types and string types. References component type.
541 -- Constant_Value (synthesized)
542 -- Applies to variables, constants, named integers, and named reals.
543 -- Obtains the initialization expression for the entity. Will return
544 -- Empty for for a deferred constant whose full view is not available
545 -- or in some other cases of internal entities, which cannot be treated
546 -- as constants from the point of view of constant folding. Empty is
547 -- also returned for variables with no initialization expression.
549 -- Corresponding_Concurrent_Type (Node18)
550 -- Present in record types that are constructed by the expander to
551 -- represent task and protected types (Is_Concurrent_Record_Type flag
552 -- set True). Points to the entity for the corresponding task type or
555 -- Corresponding_Discriminant (Node19)
556 -- Present in discriminants of a derived type, when the discriminant is
557 -- used to constrain a discriminant of the parent type. Points to the
558 -- corresponding discriminant in the parent type. Otherwise it is Empty.
560 -- Corresponding_Equality (Node13)
561 -- Present in function entities for implicit inequality operators.
562 -- Denotes the explicit or derived equality operation that creates
563 -- the implicit inequality. Note that this field is not present in
564 -- other function entities, only in implicit inequality routines,
565 -- where Comes_From_Source is always False.
567 -- Corresponding_Record_Type (Node18)
568 -- Present in protected and task types and subtypes. References the
569 -- entity for the corresponding record type constructed by the expander
570 -- (see Exp_Ch9). This type is used to represent values of the task type.
572 -- Corresponding_Remote_Type (Node22)
573 -- Present in record types that describe the fat pointer structure for
574 -- Remote_Access_To_Subrogram types. References the original access type.
576 -- CR_Discriminant (Node23)
577 -- Present in discriminants of concurrent types. Denotes the homologous
578 -- discriminant of the corresponding record type. The CR_Discriminant is
579 -- created at the same time as the discriminal, and used to replace
580 -- occurrences of the discriminant within the type declaration.
582 -- Current_Value (Node9)
583 -- Present in E_Variable, E_Out_Parameter and E_In_Out_Parameter
584 -- entities. Set non-Empty if the (constant) current value of the
585 -- variable is known. This value is valid only for references from
586 -- the same sequential scope as the entity. The sequential scope
587 -- of an entity includes the immediate scope and any contained
588 -- scopes that are package specs, package bodies, or blocks (at
589 -- any nesting level). For convenience in coding, this field is
590 -- also present in other object entities (E_Loop_Parameter and
591 -- E_In_Parameter and E_Constant), but is not used to hold a
592 -- constant value, since value tracking is not needed in this case.
594 -- Another related use of this field is to record information
595 -- about the value obtained from an IF statement condition.
596 -- If the IF/ELSIF condition has the form "[NOT] OBJ RELOP VAL",
597 -- where OBJ is a reference to an entity with a Current_Value field,
598 -- RELOP is one of the six relational operators, and VAL is a compile-
599 -- time known valoue, then the Current_Value field if OBJ is set to
600 -- point to the N_If_Statement or N_Elsif_Part node of the relevant
601 -- construct. For more details on this usage, see the procedure
602 -- Exp_Util.Get_Current_Value_Condition.
604 -- Debug_Info_Off (Flag166)
605 -- Present in all entities. Set if a pragma Suppress_Debug_Info applies
606 -- to the entity, or if internal processing in the compiler determines
607 -- that suppression of debug information is desirable. Note that this
608 -- flag is only for use by the front end as part of the processing for
609 -- determining if Needs_Debug_Info should be set. The back end should
610 -- always test Needs_Debug_Info, it should never test Debug_Info_Off.
612 -- Debug_Renaming_Link (Node13)
613 -- Used to link the enumeration literal of a debug renaming declaration
614 -- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
615 -- details of the use of this field.
617 -- Declaration_Node (synthesized)
618 -- Applies to all entities. Returns the tree node for the declaration
619 -- that declared the entity. Normally this is just the Parent of the
620 -- entity. One exception arises with child units, where the parent of
621 -- the entity is a selected component or a defining program unit name.
622 -- Another exception is that if the entity is an incomplete type that
623 -- has been completed, then we obtain the declaration node denoted by
624 -- the full type, i.e. the full type declaration node.
626 -- Default_Expr_Function (Node21)
627 -- Present in parameters. It holds the entity of the parameterless
628 -- function that is built to evaluate the default expression if it is
629 -- more complex than a simple identifier or literal. For the latter
630 -- simple cases or if there is no default value, this field is Empty.
632 -- Default_Expressions_Processed (Flag108)
633 -- A flag in subprograms (functions, operators, procedures) and in
634 -- entries and entry families used to indicate that default expressions
635 -- have been processed and to avoid multiple calls to process the
636 -- default expressions (see Freeze.Process_Default_Expressions), which
637 -- would not only waste time, but also generate false error messages.
639 -- Default_Value (Node20)
640 -- Present in formal parameters. Points to the node representing the
641 -- expression for the default value for the parameter. Empty if the
642 -- parameter has no default value (which is always the case for OUT
643 -- and IN OUT parameters in the absence of errors).
645 -- Delay_Cleanups (Flag114)
646 -- Present in entities that have finalization lists (subprograms
647 -- blocks, and tasks). Set if there are pending generic body
648 -- instantiations for the corresponding entity. If this flag is
649 -- set, then generation of cleanup actions for the corresponding
650 -- entity must be delayed, since the insertion of the generic body
651 -- may affect cleanup generation (see Inline for further details).
653 -- Delay_Subprogram_Descriptors (Flag50)
654 -- Present in entities for which exception subprogram descriptors
655 -- are generated (subprograms, package declarations and package
656 -- bodies). Present if there are pending generic body instantiations
657 -- for the corresponding entity. If this flag is set, then generation
658 -- of the subprogram descriptor for the corresponding enities must
659 -- be delayed, since the insertion of the generic body may add entries
660 -- to the list of handlers.
662 -- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
663 -- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
664 -- a block (in which case Delay_Subprogram_Descriptors is set for the
665 -- containing subprogram). In addition Delay_Subprogram_Descriptors is
666 -- set for a library level package declaration or body which contains
667 -- delayed instantiations (in this case the descriptor refers to the
668 -- enclosing elaboration procedure).
670 -- Delta_Value (Ureal18)
671 -- Present in fixed and decimal types. Points to a universal real
672 -- that holds value of delta for the type, as given in the declaration
673 -- or as inherited by a subtype or derived type.
675 -- Dependent_Instances (Elist8)
676 -- Present in packages that are instances. Holds list of instances
677 -- of inner generics. Used to place freeze nodes for those instances
678 -- after that of the current one, i.e. after the corresponding generic
681 -- Depends_On_Private (Flag14)
682 -- Present in all type entities. Set if the type is private or if it
683 -- depends on a private type.
685 -- Designated_Type (synthesized)
686 -- Applies to access types. Returns the designated type. Differs
687 -- from Directly_Designated_Type in that if the access type refers
688 -- to an incomplete type, and the full type is available, then this
689 -- full type is returned instead of the incomplete type.
691 -- Digits_Value (Uint17)
692 -- Present in floating point types and subtypes and decimal types and
693 -- subtypes. Contains the Digits value specified in the declaration.
695 -- Directly_Designated_Type (Node20)
696 -- Present in access types. This field points to the type that is
697 -- directly designated by the access type. In the case of an access
698 -- type to an incomplete type, this field references the incomplete
699 -- type. Note that in the semantic processing, what is useful in
700 -- nearly all cases is the full type designated by the access type.
701 -- The function Designated_Type obtains this full type in the case of
702 -- access to an incomplete type.
704 -- Discard_Names (Flag88)
705 -- Present in types and exception entities. Set if pragma Discard_Names
706 -- applies to the entity. It is also set for declarative regions and
707 -- package specs for which a Discard_Names pragma with zero arguments
708 -- has been encountered. The purpose of setting this flag is to be able
709 -- to set the Discard_Names attribute on enumeration types declared
710 -- after the pragma within the same declarative region. This flag is
711 -- set to False if a Keep_Names pragma appears for an enumeration type.
713 -- Discriminal (Node17)
714 -- Present in discriminants (Discriminant formal: GNAT's first
715 -- coinage). The entity used as a formal parameter that corresponds
716 -- to a discriminant. See section "Handling of Discriminants" for
717 -- full details of the use of discriminals.
719 -- Discriminal_Link (Node10)
720 -- Present in discriminals (which have an Ekind of E_In_Parameter,
721 -- or E_Constant), points back to corresponding discriminant.
723 -- Discriminant_Checking_Func (Node20)
724 -- Present in components. Points to the defining identifier of the
725 -- function built by the expander returns a Boolean indicating whether
726 -- the given record component exists for the current discriminant
729 -- Discriminant_Constraint (Elist21)
730 -- Present in entities whose Has_Discriminants flag is set (concurrent
731 -- types, subtypes, record types and subtypes, private types and
732 -- subtypes, limited private types and subtypes and incomplete types).
733 -- It is an error to reference the Discriminant_Constraint field if
734 -- Has_Discriminants is False.
736 -- If the Is_Constrained flag is set, Discriminant_Constraint points
737 -- to an element list containing the discriminant constraints in the
738 -- same order in which the discriminants are declared.
740 -- If the Is_Constrained flag is not set but the discriminants of the
741 -- unconstrained type have default initial values then this field
742 -- points to an element list giving these default initial values in
743 -- the same order in which the discriminants are declared. Note that
744 -- in this case the entity cannot be a tagged record type, because
745 -- discriminants in this case cannot have defaults.
747 -- If the entity is a tagged record implicit type, then this field is
748 -- inherited from the first subtype (so that the itype is subtype
749 -- conformant with its first subtype, which is needed when the first
750 -- subtype overrides primitive operations inherited by the implicit
753 -- In all other cases Discriminant_Constraint contains the empty
754 -- Elist (ie it is initialized with a call to New_Elmt_List).
756 -- Discriminant_Default_Value (Node20)
757 -- Present in discriminants. Points to the node representing the
758 -- expression for the default value of the discriminant. Set to
759 -- Empty if the discriminant has no default value.
761 -- Discriminant_Number (Uint15)
762 -- Present in discriminants. Gives the ranking of a discriminant in
763 -- the list of discriminants of the type, i.e. a sequential integer
764 -- index starting at 1 and ranging up to Number_Discriminants.
766 -- DTC_Entity (Node16)
767 -- Present in function and procedure entities. Set to Empty unless
768 -- the subprogram is dispatching in which case it references the
769 -- Dispatch Table pointer Component. That is to say the component _tag
770 -- for regular Ada tagged types, for CPP_Class types and their
771 -- descendants this field points to the component entity in the record
772 -- that is the Vtable pointer for the Vtable containing the entry that
773 -- references the subprogram.
775 -- DT_Entry_Count (Uint15)
776 -- Present in E_Component entities. Only used for component marked
777 -- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
779 -- DT_Position (Uint15)
780 -- Present in function and procedure entities which are dispatching
781 -- (should not be referenced without first checking that flag
782 -- Is_Dispatching_Operation is True). Contains the offset into
783 -- the Vtable for the entry that references the subprogram.
786 -- Present in all entities. Contains a value of the enumeration type
787 -- Entity_Kind declared in a subsequent section in this spec.
789 -- Elaborate_All_Desirable (Flag146)
790 -- Present in package and subprogram entities, and in generic package
791 -- and subprogram entities. Set if internal analysis of a client that
792 -- with's this unit determines that Elaborate_All is desirable, i.e.
793 -- that there is a possibility that Program_Error may be raised if
794 -- Elaborate_All conditions cannot be met.
796 -- Elaboration_Entity (Node13)
797 -- Present in generic and non-generic package and subprogram
798 -- entities. This is a boolean entity associated with the unit that
799 -- is initiallly set to False, and is set True when the unit is
800 -- elaborated. This is used for two purposes. First, it is used to
801 -- implement required access before elaboration checks (the flag
802 -- must be true to call a subprogram at elaboration time). Second,
803 -- it is used to guard against repeated execution of the generated
806 -- Note that we always allocate this flag, and set this field, but
807 -- we do not always actually use it. It is only used if it is needed
808 -- for access-before-elaboration use (see Elaboration_Entity_Required
809 -- flag) or if either the spec or the body has elaboration code. If
810 -- neither of these two conditions holds, then the entity is still
811 -- allocated (since we don't know early enough whether or not there
812 -- is elaboration code), but is simply not used for any purpose.
814 -- Elaboration_Entity_Required (Flag174)
815 -- Present in generics and non-generic package and subprogram
816 -- entities. Set only if Elaboration_Entity is non-Empty to indicate
817 -- that the boolean is required to be set even if there is no other
818 -- elaboration code. This occurs when the Elaboration_Entity flag
819 -- is used for required access-before-elaboration checking. If the
820 -- flag is only for preventing multiple execution of the elaboration
821 -- code, then if there is no other elaboration code, obviously there
822 -- is no need to set the flag.
824 -- Enclosing_Dynamic_Scope (synthesized)
825 -- Appliesa to all entities. Returns the closest dynamic scope in which
826 -- the entity is declared or Standard_Standard for library-level entities
828 -- Enclosing_Scope (Node18)
829 -- Present in labels. Denotes the innermost enclosing construct that
830 -- contains the label. Identical to the scope of the label, except for
831 -- labels declared in the body of an accept statement, in which case the
832 -- entry_name is the Enclosing_Scope. Used to validate goto's within
833 -- accept statements.
835 -- Entry_Accepted (Flag152)
836 -- Present in E_Entry and E_Entry_Family entities. Set if there is
837 -- at least one accept for this entry in the task body. Used to
838 -- generate warnings for missing accepts.
840 -- Entry_Bodies_Array (Node15)
841 -- Present in protected types for which Has_Entries is true.
842 -- This is the defining identifier for the array of entry body
843 -- action procedures and barrier functions used by the runtime to
844 -- execute the user code associated with each entry.
846 -- Entry_Cancel_Parameter (Node23)
847 -- Present in blocks. This only applies to a block statement for
848 -- which the Is_Asynchronous_Call_Block flag is set. It
849 -- contains the defining identifier of an object that must be
850 -- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
851 -- call in the cleanup handler added to the block by
852 -- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
853 -- object for task entry calls and a Communications_Block object
854 -- in the case of protected entry calls. In both cases the objects
855 -- are declared in outer scopes to this block.
857 -- Entry_Component (Node11)
858 -- Present in formal parameters (in, in out and out parameters). Used
859 -- only for formals of entries. References the corresponding component
860 -- of the entry parameter record for the entry.
862 -- Entry_Formal (Node16)
863 -- Present in components of the record built to correspond to entry
864 -- parameters. This field points from the component to the formal. It
865 -- is the back pointer corresponding to Entry_Component.
867 -- Entry_Index_Constant (Node18)
868 -- Present in an entry index parameter. This is an identifier that
869 -- eventually becomes the name of a constant representing the index
870 -- of the entry family member whose entry body is being executed. Used
871 -- to expand references to the entry index specification identifier.
873 -- Entry_Index_Type (synthesized)
874 -- Applies to an entry family. Denotes Etype of the subtype indication
875 -- in the entry declaration. Used to resolve the index expression in an
876 -- accept statement for a member of the family, and in the prefix of
877 -- 'COUNT when it applies to a family member.
879 -- Entry_Parameters_Type (Node15)
880 -- Present in entries. Points to the access-to-record type that is
881 -- constructed by the expander to hold a reference to the parameter
882 -- values. This reference is manipulated (as an address) by the
883 -- tasking runtime. The designated record represents a packaging
884 -- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
885 -- for further details). Entry_Parameters_Type is Empty if the entry
886 -- has no parameters.
888 -- Enumeration_Pos (Uint11)
889 -- Present in enumeration literals. Contains the position number
890 -- corresponding to the value of the enumeration literal.
892 -- Enumeration_Rep (Uint12)
893 -- Present in enumeration literals. Contains the representation that
894 -- corresponds to the value of the enumeration literal. Note that
895 -- this is normally the same as Enumeration_Pos except in the presence
896 -- of representation clauses, where Pos will still represent the
897 -- position of the literal within the type and Rep will have be the
898 -- value given in the representation clause.
900 -- Enumeration_Rep_Expr (Node22)
901 -- Present in enumeration literals. Points to the expression in an
902 -- associated enumeration rep clause that provides the representation
903 -- value for this literal. Empty if no enumeration rep clause for this
904 -- literal (or if rep clause does not have an entry for this literal,
905 -- an error situation). This is also used to catch duplicate entries
906 -- for the same literal.
908 -- Enum_Pos_To_Rep (Node23)
909 -- Present in enumeration types (but not enumeration subtypes). Set to
910 -- Empty unless the enumeration type has a non-standard representation
911 -- (i.e. at least one literal has a representation value different from
912 -- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
913 -- array constructed when the type is frozen that maps Pos values to
914 -- corresponding Rep values. The index type of this array is Natural,
915 -- and the component type is a suitable integer type that holds the
916 -- full range of representation values.
918 -- Equivalent_Type (Node18)
919 -- Present in class wide types and subtypes, access to protected
920 -- subprogram types, and in exception_types. For a classwide type, it
921 -- is always Empty. For a class wide subtype, it points to an entity
922 -- created by the expander which gives Gigi an easily understandable
923 -- equivalent of the class subtype with a known size (given by an
924 -- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
925 -- details. For E_exception_type, this points to the record containing
926 -- the data necessary to represent exceptions (for further details, see
927 -- System.Standard_Library. For access_to_protected subprograms, it
928 -- denotes a record that holds pointers to the operation and to the
929 -- protected object. For remote Access_To_Subprogram types, it denotes
930 -- the record that is the fat pointer representation of an RAST.
933 -- Present in all types and subtypes, and also for components, constants,
934 -- and variables. Contains the Object_Size of the type or of the object.
935 -- A value of zero indicates that the value is not yet known.
937 -- For the case of components where a component clause is present, the
938 -- value is the value from the component clause, which must be non-
939 -- negative (but may be zero, which is acceptable for the case of
940 -- a type with only one possible value). It is also possible for Esize
941 -- of a component to be set without a component clause present, which
942 -- means that the component size is specified, but not the position.
943 -- See also RM_Size and the section on "Handling of Type'Size Values".
944 -- During gigi processing, the value is back annotated for all zero
945 -- values, so that after the call to gigi, the value is properly set.
948 -- Present in all entities. Represents the type of the entity, which
949 -- is itself another entity. For a type entity, points to the parent
950 -- type for a derived type, or if the type is not derived, points to
951 -- itself. For a subtype entity, Etype points to the base type. For
952 -- a class wide type, points to the parent type. For a subprogram or
953 -- subprogram type, Etype has the return type of a function or is set
954 -- to Standard_Void_Type to represent a procedure.
956 -- Exception_Code (Uint22)
957 -- Present in exception entitites. Set to zero unless either an
958 -- Import_Exception or Export_Exception pragma applies to the
959 -- pragma and specifies a Code value. See description of these
960 -- pragmas for details. Note that this field is relevant only if
961 -- Is_VMS_Exception is set.
963 -- Extra_Formal (Node15)
964 -- Present in formal parameters in the non-generic case. Certain
965 -- parameters require extra implicit information to be passed
966 -- (e.g. the flag indicating if an unconstrained variant record
967 -- argument is constrained, and the accessibility level for
968 -- access parameters. See description of Extra_Constrained,
969 -- Extra_Accessibility fields for further details. Extra formal
970 -- parameters are constructed to represent these values, and
971 -- chained to the end of the list of formals using the
972 -- Extra_Formal field (i.e. the Extra_Formal field of the last
973 -- "real" formal points to the first extra formal, and the
974 -- Extra_Formal field of each extra formal points to the next
975 -- one, with Empty indicating the end of the list of extra
978 -- Extra_Accessibility (Node13)
979 -- Present in formal parameters in the non-generic case if
980 -- expansion is active. Normally Empty, but if a parameter is
981 -- one for which a dynamic accessibility check is required, then
982 -- an extra formal of type Natural is created (see description
983 -- of field Extra_Formal), and the Extra_Accessibility field of
984 -- the formal parameter points to the entity for this extra
985 -- formal. Also present in variables when compiling receiving
986 -- stubs. In this case, a non Empty value means that this
987 -- variable's accessibility depth has been transmitted by the
988 -- caller and must be retrieved through the entity designed by
989 -- this field instead of being computed.
991 -- Extra_Constrained (Node23)
992 -- Present in formal parameters in the non-generic case if
993 -- expansion is active. Normally Empty, but if a parameter is
994 -- one for which a dynamic indication of its constrained status
995 -- is required, then an extra formal of type Boolean is created
996 -- (see description of field Extra_Formal), and the
997 -- Extra_Constrained field of the formal parameter points to the
998 -- entity for this extra formal. Also present in variables when
999 -- compiling receiving stubs. In this case, a non empty value
1000 -- means that this variable's constrained status has been
1001 -- transmitted by the caller and must be retrieved through the
1002 -- entity designed by this field instead of being computed.
1004 -- Finalization_Chain_Entity (Node19)
1005 -- Present in scopes which can have finalizable entities (blocks,
1006 -- functions, procedures, tasks, entries). When this field is empty it
1007 -- means that there are no finalization actions to perform on exit of the
1008 -- scope. When this field contains 'Error', it means that no
1009 -- finalization actions should happen at this level and the
1010 -- finalization chain of a parent scope shall be used (??? this is
1011 -- an improper use of 'Error' and should be changed). otherwise it
1012 -- contains an entity of type Finalizable_Ptr that is the head of the
1013 -- list of objects to finalize on exit. See "Finalization Management"
1014 -- section in exp_ch7.adb for more details.
1016 -- Finalize_Storage_Only (Flag158) [base type only]
1017 -- Present in all types. Set on direct controlled types to which a
1018 -- valid Finalize_Storage_Only pragma applies. This flag is also set on
1019 -- composite types when they have at least one controlled component and
1020 -- all their controlled components are Finalize_Storage_Only. It is also
1021 -- inherited by type derivation except for direct controlled types where
1022 -- the Finalize_Storage_Only pragma is required at each level of
1025 -- First_Component (synthesized)
1026 -- Applies to record types. Returns the first component by following
1027 -- the chain of declared entities for the record until a component
1028 -- is found (one with an Ekind of E_Component). The discriminants are
1029 -- skipped. If the record is null, then Empty is returned.
1031 -- First_Discriminant (synthesized)
1032 -- Applies to types with discriminants. The discriminants are the
1033 -- first entities declared in the type, so normally this is equivalent
1034 -- to First_Entity. The exception arises for tagged types, where the
1035 -- tag itself is prepended to the front of the entity chain, so the
1036 -- First_Discriminant function steps past the tag if it is present.
1038 -- First_Entity (Node17)
1039 -- Present in all entities which act as scopes to which a list of
1040 -- associated entities is attached (blocks, class subtypes and types,
1041 -- entries, functions, loops, packages, procedures, protected objects,
1042 -- record types and subtypes, private types, task types and subtypes).
1043 -- Points to a list of associated entities using the Next_Entity field
1044 -- as a chain pointer with Empty marking the end of the list.
1046 -- First_Formal (synthesized)
1047 -- Applies to subprograms and subprogram types, and also in entries
1048 -- and entry families. Returns first formal of the subprogram or entry.
1049 -- The formals are the first entities declared in a subprogram or in
1050 -- a subprogram type (the designated type of an Access_To_Subprogram
1051 -- definition) or in an entry.
1053 -- First_Index (Node17)
1054 -- Present in array types and subtypes and in string types and subtypes.
1055 -- By introducing implicit subtypes for the index constraints, we have
1056 -- the same structure for constrained and unconstrained arrays, subtype
1057 -- marks and discrete ranges are both represented by a subtype. This
1058 -- function returns the tree node corresponding to an occurrence of the
1059 -- first index (NOT the entity for the type). Subsequent indexes are
1060 -- obtained using Next_Index. Note that this field is present for the
1061 -- case of string literal subtypes, but is always Empty.
1063 -- First_Literal (Node17)
1064 -- Present in all enumeration types, including character and boolean
1065 -- types. This field points to the first enumeration literal entity
1066 -- for the type (i.e. it is set to First (Literals (N)) where N is
1067 -- the enumeration type definition node. A special case occurs with
1068 -- standard character and wide character types, where this field is
1069 -- Empty, since there are no enumeration literal lists in these cases.
1070 -- Note that this field is set in enumeration subtypes, but it still
1071 -- points to the first literal of the base type in this case.
1073 -- First_Optional_Parameter (Node14)
1074 -- Present in (non-generic) function and procedure entities. Set to a
1075 -- non-null value only if a pragma Import_Function, Import_Procedure
1076 -- or Import_Valued_Procedure specifies a First_Optional_Parameter
1077 -- argument, in which case this field points to the parameter entity
1078 -- corresponding to the specified parameter.
1080 -- First_Private_Entity (Node16)
1081 -- Present in all entities containing private parts (packages,
1082 -- protected types and subtypes, task types and subtypes). The
1083 -- entities on the entity chain are in order of declaration, so the
1084 -- entries for private entities are at the end of the chain. This
1085 -- field points to the first entity for the private part. It is
1086 -- Empty if there are no entities declared in the private part or
1087 -- if there is no private part.
1089 -- First_Rep_Item (Node6)
1090 -- Present in all entities. If non-empty, points to a linked list of
1091 -- representation pragmas nodes and representation clause nodes that
1092 -- apply to the entity, linked using Next_Rep_Item, with Empty marking
1093 -- the end of the list. In the case of derived types and subtypes, the
1094 -- new entity inherits the chain at the point of declaration. This
1095 -- means that it is possible to have multiple instances of the same
1096 -- kind of rep item on the chain, in which case it is the first one
1097 -- that applies to the entity.
1099 -- For most representation items, the representation information is
1100 -- reflected in other fields and flags in the entity. For example if
1101 -- a record representation clause is present, the component entities
1102 -- reflect the specified information. However, there are some items
1103 -- that are only reflected in the chain. These include:
1105 -- Alignment attribute definition clause
1106 -- Machine_Attribute pragma
1107 -- Link_Alias pragma
1108 -- Link-Section pragma
1109 -- Weak_External pragma
1111 -- If any of these items are present, then the flag Has_Gigi_Rep_Item
1112 -- is set, indicating that Gigi should search the chain.
1114 -- Other representation items are included in the chain so that error
1115 -- messages can easily locate the relevant nodes for posting errors.
1116 -- Note in particular that size clauses are present only for this
1117 -- purpose, and should only be accessed if Has_Size_Clause is set.
1119 -- First_Stored_Discriminant (synthesized)
1120 -- Applies to types with discriminants. Gives the first discriminant
1121 -- stored in the object. In many cases, these are the same as the
1122 -- normal visible discriminants for the type, but in the case of
1123 -- renamed discriminants, this is not always the case.
1125 -- For tagged types, and untagged types which are root types or
1126 -- derived types but which do not rename discriminants in their
1127 -- root type, the stored discriminants are the same as the actual
1128 -- discriminants of the type, and hence this function is the same
1129 -- as First_Discriminant.
1131 -- For derived non-tagged types that rename discriminants in the root
1132 -- type this is the first of the discriminants that occurr in the
1133 -- root type. To be precise, in this case stored discriminants are
1134 -- entities attached to the entity chain of the derived type which
1135 -- are a copy of the discriminants of the root type. Furthermore their
1136 -- Is_Completely_Hidden flag is set since although they are actually
1137 -- stored in the object, they are not in the set of discriminants that
1138 -- is visble in the type.
1140 -- For derived untagged types, stored discriminants are the real
1141 -- discriminants from Gigi's standpoint, i.e. those that will be
1142 -- stored in actual objects of the type.
1144 -- First_Subtype (synthesized)
1145 -- Applies to all types and subtypes. For types, yields the first
1146 -- subtype of the type. For subtypes, yields the first subtype of
1147 -- the base type of the subtype.
1149 -- Freeze_Node (Node7)
1150 -- Present in all entities. If there is an associated freeze node for
1151 -- the entity, this field references this freeze node. If no freeze
1152 -- node is associated with the entity, then this field is Empty. See
1153 -- package Freeze for further details.
1155 -- From_With_Type (Flag159)
1156 -- Present in package and type entities. Indicates that the entity
1157 -- appears in a With_Type clause in the context of some other unit,
1158 -- either as the prefix (which must be a package), or as a type name.
1159 -- The package can only be used to retrieve such a type, and the type
1160 -- can be used only in component declarations and access definitions.
1161 -- The With_Type clause is used to construct mutually recursive
1162 -- types, i.e. record types (Java classes) that hold pointers to each
1163 -- other. If such a type is an access type, it has no explicit freeze
1164 -- node, so that the back-end does not attempt to elaborate it.
1165 -- Currently this flag is also used to implement Ada 2005 (AI-50217).
1166 -- It will be renamed to From_Limited_With after removal of the current
1167 -- GNAT with_type clause???
1169 -- Full_View (Node11)
1170 -- Present in all type and subtype entities and in deferred constants.
1171 -- References the entity for the corresponding full type declaration.
1172 -- For all types other than private and incomplete types, this field
1173 -- always contains Empty. See also Underlying_Type.
1175 -- Function_Returns_With_DSP (Flag169)
1176 -- Present in all subprogram entities, and type entities for access
1177 -- to subprogram values. Set True if the function (or referenced
1178 -- function in the case of an access value) returns with using the
1179 -- DSP (depressed stack pointer) approach. This can only be set
1180 -- True if Targparm.Functions_Return_By_DSP_On_Target is True and
1181 -- the function returns a value of a type whose size is not known
1184 -- Generic_Homonym (Node11)
1185 -- Present in generic packages. The generic homonym is the entity of
1186 -- a renaming declaration inserted in every generic unit. It is used
1187 -- to resolve the name of a local entity that is given by a qualified
1188 -- name, when the generic entity itself is hidden by a local name.
1190 -- Generic_Renamings (Elist23)
1191 -- Present in package and subprogram instances. Holds mapping that
1192 -- associates generic parameters with the corresponding instances, in
1193 -- those cases where the instance is an entity.
1195 -- Handler_Records (List10)
1196 -- Present in subprogram and package entities. Points to a list of
1197 -- identifiers referencing the handler record entities for the
1198 -- corresponding unit.
1200 -- Has_Aliased_Components (Flag135) [implementation base type only]
1201 -- Present in array type entities. Indicates that the component type
1202 -- of the array is aliased.
1204 -- Has_Alignment_Clause (Flag46)
1205 -- Present in all type entities and objects. Indicates if an alignment
1206 -- clause has been given for the entity. If set, then Alignment_Clause
1207 -- returns the N_Attribute_Definition node for the alignment attribute
1208 -- definition clause. Note that it is possible for this flag to be False
1209 -- even when Alignment_Clause returns non_Empty (this happens in the case
1210 -- of derived type declarations).
1212 -- Has_All_Calls_Remote (Flag79)
1213 -- Present in all library unit entities. Set true if the library unit
1214 -- has an All_Calls_Remote pragma. Note that such entities must also
1215 -- be RCI entities, so the flag Is_Remote_Call_Interface will always
1216 -- be set if this flag is set.
1218 -- Has_Atomic_Components (Flag86) [implementation base type only]
1219 -- Present in all types and objects. Set only for an array type or
1220 -- an array object if a valid pragma Atomic_Components applies to the
1221 -- type or object. Note that in the case of an object, this flag is
1222 -- only set on the object if there was an explicit pragma for the
1223 -- object. In other words, the proper test for whether an object has
1224 -- atomic components is to see if either the object or its base type
1225 -- has this flag set. Note that in the case of a type, the pragma will
1226 -- be chained to the rep item chain of the first subtype in the usual
1229 -- Has_Attach_Handler (synthesized)
1230 -- Applies to record types that are constructed by the expander to
1231 -- represent protected types. Returns True if there is at least one
1232 -- Attach_Handler pragma in the corresponding specification.
1234 -- Has_Biased_Representation (Flag139)
1235 -- Present in discrete types (where it applies to the type'size value),
1236 -- and to objects (both stand-alone and components), where it applies to
1237 -- the size of the object from a size or record component clause. In
1238 -- all cases it indicates that the size in question is smaller than
1239 -- would normally be required, but that the size requirement can be
1240 -- satisfied by using a biased representation, in which stored values
1241 -- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
1242 -- reduce the required size. For example, a type with a range of 1..2
1243 -- takes one bit, using 0 to represent 1 and 1 to represent 2.
1245 -- Note that in the object and component cases, the flag is only set
1246 -- if the type is unbiased, but the object specifies a smaller size
1247 -- than the size of the type, forcing biased representation for the
1248 -- object, but the subtype is still an unbiased type.
1250 -- Has_Completion (Flag26)
1251 -- Present in all entities that require a completion (functions,
1252 -- procedures, private types, limited private types, incomplete types,
1253 -- constants and packages that require a body). The flag is set if the
1254 -- completion has been encountered and analyzed.
1256 -- Has_Completion_In_Body (Flag71)
1257 -- Present in "Taft amendment types" that is to say incomplete types
1258 -- whose full declaration appears in the package body.
1260 -- Has_Complex_Representation (Flag140) [implementation base type only]
1261 -- Present in all type entities. Set only for a record base type to
1262 -- which a valid pragma Complex_Representation applies.
1264 -- Has_Component_Size_Clause (Flag68) [implementation base type only]
1265 -- Present in all type entities. Set if a component size clause is
1266 -- present for the given type. Note that this flag can be False even
1267 -- if Component_Size is non-zero (happens in the case of derived types).
1269 -- Has_Contiguous_Rep (Flag181)
1270 -- Present in enumeration types. True if the type as a representation
1271 -- clause whose entries are successive integers.
1273 -- Has_Controlling_Result (Flag98)
1274 -- Present in E_Function entities. True if The function is a primitive
1275 -- function of a tagged type which can dispatch on result
1277 -- Has_Controlled_Component (Flag43) [base type only]
1278 -- Present in composite type entities. Indicates that the type has a
1279 -- component that either is a controlled type, or itself contains a
1280 -- controlled component (i.e. either Has_Controlled_Component or
1281 -- Is_Controlled is set for at least one component).
1283 -- Has_Convention_Pragma (Flag119)
1284 -- Present in an entity for which a Convention, Import, or Export
1285 -- pragma has been given. Used to prevent more than one such pragma
1286 -- appearing for a given entity (RM B.1(45)).
1288 -- Has_Delayed_Freeze (Flag18)
1289 -- Present in all entities. Set to indicate that an explicit freeze
1290 -- node must be generated for the entity at its freezing point. See
1291 -- separate section ("Delayed Freezing and Elaboration") for details.
1293 -- Has_Discriminants (Flag5)
1294 -- Present in all types and subtypes. For types that are allowed to have
1295 -- discriminants (record types and subtypes, task types and subtypes,
1296 -- protected types and subtypes, private types, limited private types,
1297 -- and incomplete types), indicates if the corresponding type or subtype
1298 -- has a known discriminant part. Always false for all other types.
1300 -- Has_Entries (synthesized)
1301 -- Applies to concurrent types. True if any entries are declared
1302 -- within the task or protected definition for the type.
1304 -- Has_Enumeration_Rep_Clause (Flag66)
1305 -- Present in enumeration types. Set if an enumeration representation
1306 -- clause has been given for this enumeration type. Used to prevent more
1307 -- than one enumeration representation clause for a given type. Note
1308 -- that this does not imply a representation with holes, since the rep
1309 -- clause may merely confirm the default 0..N representation.
1311 -- Has_External_Tag_Rep_Clause (Flag110)
1312 -- Present in tagged types. Set if an external_tag rep. clause has been
1313 -- given for this type. Use to avoid the generation of the default
1316 -- Has_Exit (Flag47)
1317 -- Present in loop entities. Set if the loop contains an exit statement.
1319 -- Has_Foreign_Convention (synthesized)
1320 -- Applies to all entities. Determines if the Convention for the
1321 -- entity is a foreign convention (i.e. is other than Convention_Ada,
1322 -- Convention_Intrinsic, Convention_Entry or Convention_Protected).
1324 -- Has_Forward_Instantiation (Flag175)
1325 -- Present in package entities. Set true for packages that contain
1326 -- instantiations of local generic entities, before the corresponding
1327 -- generic body has been seen. If a package has a forward instantiation,
1328 -- we cannot inline subprograms appearing in the same package because
1329 -- the placement requirements of the instance will conflict with the
1330 -- linear elaboration of front-end inlining.
1332 -- Has_Fully_Qualified_Name (Flag173)
1333 -- Present in all entities. Set True if the name in the Chars field
1334 -- has been replaced by the fully qualified name, as used for debug
1335 -- output. See Exp_Dbug for a full description of the use of this
1336 -- flag and also the related flag Has_Qualified_Name.
1338 -- Has_Gigi_Rep_Item (Flag82)
1339 -- This flag is set if the rep item chain (referenced by First_Rep_Item
1340 -- and linked through the Next_Rep_Item chain contains a representation
1341 -- item that needs to be specially processed by Gigi, i.e. one of the
1344 -- Machine_Attribute pragma
1345 -- Linker_Alias pragma
1346 -- Linker_Section pragma
1347 -- Weak_External pragma
1349 -- If this flag is set, then Gigi should scan the rep item chain to
1350 -- process any of these items that appear. At least one such item will
1353 -- Has_Homonym (Flag56)
1354 -- Present in all entities. Set if an entity has a homonym in the same
1355 -- scope. Used by Gigi to generate unique names for such entities.
1357 -- Has_Interrupt_Handler (synthesized)
1358 -- Applies to all protected type entities. Set if the protected type
1359 -- definition contains at least one procedure to which a pragma
1360 -- Interrupt_Handler applies.
1362 -- Has_Machine_Radix_Clause (Flag83)
1363 -- Present in decimal types and subtypes, set if a Machine_Radix
1364 -- representation clause is present. This flag is used to detect
1365 -- the error of multiple machine radix clauses for a single type.
1367 -- Has_Master_Entity (Flag21)
1368 -- Present in entities that can appear in the scope stack (see spec
1369 -- of Sem). It is set if a task master entity (_master) has been
1370 -- declared and initialized in the corresponding scope.
1372 -- Has_Missing_Return (Flag142)
1373 -- Present in functions and generic functions. Set if there is one or
1374 -- more missing return statements in the function. This is used to
1375 -- control wrapping of the body in Exp_Ch6 to ensure that the program
1376 -- error exeption is correctly raised in this case at runtime.
1378 -- Has_Nested_Block_With_Handler (Flag101)
1379 -- Present in scope entities. Set if there is a nested block within the
1380 -- scope that has an exception handler and the two scopes are in the
1381 -- same procedure. This is used by the backend for controlling certain
1382 -- optimizations to ensure that they are consistent with exceptions.
1383 -- See documentation in Gigi for further details.
1385 -- Has_Non_Standard_Rep (Flag75) [implementation base type only]
1386 -- Present in all type entities. Set when some representation clause
1387 -- or pragma causes the representation of the item to be significantly
1388 -- modified. In this category are changes of small or radix for a
1389 -- fixed-point type, change of component size for an array, and record
1390 -- or enumeration representation clauses, as well as packed pragmas.
1391 -- All other representation clauses (e.g. Size and Alignment clauses)
1392 -- are not considered to be significant since they do not affect
1393 -- stored bit patterns.
1395 -- Has_Object_Size_Clause (Flag172)
1396 -- Present in entities for types and subtypes. Set if an Object_Size
1397 -- clause has been processed for the type Used to prevent multiple
1398 -- Object_Size clauses for a given entity.
1400 -- Has_Per_Object_Constraint (Flag154)
1401 -- Present in E_Component entities, true if the subtype of the
1402 -- component has a per object constraint, i.e. an actual discriminant
1403 -- value of the form T'Access, where T is the enclosing type.
1405 -- Has_Pragma_Controlled (Flag27) [implementation base type only]
1406 -- Present in access type entities. It is set if a pragma Controlled
1407 -- applies to the access type.
1409 -- Has_Pragma_Elaborate_Body (Flag150)
1410 -- Present in all entities. Set in compilation unit entities if a
1411 -- pragma Elaborate_Body applies to the compilation unit.
1413 -- Has_Pragma_Inline (Flag157)
1414 -- Present in all entities. Set for functions and procedures for which
1415 -- a pragma Inline or Inline_Always applies to the subprogram. Note
1416 -- that this flag can be set even if Is_Inlined is not set. This
1417 -- happens for pragma Inline (if Inline_Active is False). In other
1418 -- words, the flag Has_Pragma_Inline represents the formal semantic
1419 -- status, and is used for checking semantic correctness.
1420 -- The flag Is_Inlined indicates whether inlining is actually active
1423 -- Has_Pragma_Pack (Flag121) [implementation base type only]
1424 -- Present in all entities. It indicates that a valid pragma Pack was
1425 -- was given for the type. Note that this flag is not inherited by a
1426 -- derived type. See also the Is_Packed flag.
1428 -- Has_Pragma_Pure_Function (Flag179)
1429 -- Present in subprogram entities. It indicates that a valid pragma
1430 -- Pure_Function was given for the entity. In some cases, we need to
1431 -- know that Is_Pure was explicitly set using this pragma.
1433 -- Has_Pragma_Unreferenced (Flag180)
1434 -- Present in all entities. Set if a valid pragma Unreferenced applies
1435 -- to the pragma, indicating that no warning should be given if the
1436 -- entity has no references, but a warning should be given if it is
1437 -- in fact referenced.
1439 -- Has_Primitive_Operations (Flag120) [base type only]
1440 -- Present in all type entities. Set if at least one primitive operation
1441 -- is defined for the type.
1443 -- Has_Private_Ancestor (synthesized)
1444 -- Applies to all type and subtype entities. Returns True if at least
1445 -- one ancestor is private, and otherwise False if there are no private
1448 -- Has_Private_Declaration (Flag155)
1449 -- Present in all entities. Returns True if it is the defining entity
1450 -- of a private type declaration or its corresponding full declaration.
1451 -- This flag is thus preserved when the full and the partial views are
1452 -- exchanged, to indicate if a full type declaration is a completion.
1453 -- Used for semantic checks in E.4 (18), and elsewhere.
1455 -- Has_Qualified_Name (Flag161)
1456 -- Present in all entities. Set True if the name in the Chars field
1457 -- has been replaced by its qualified name, as used for debug output.
1458 -- See Exp_Dbug for a full description of qualification requirements.
1459 -- For some entities, the name is the fully qualified name, but there
1460 -- are exceptions. In particular, for local variables in procedures,
1461 -- we do not include the procedure itself or higher scopes. See also
1462 -- the flag Has_Fully_Qualified_Name, which is set if the name does
1463 -- indeed include the fully qualified name.
1465 -- Has_Record_Rep_Clause (Flag65) [implementation base type only]
1466 -- Present in record types. Set if a record representation clause has
1467 -- been given for this record type. Used to prevent more than one such
1468 -- clause for a given record type. Note that this is initially cleared
1469 -- for a derived type, even though the representation is inherited. See
1470 -- also the flag Has_Specified_Layout.
1472 -- Has_Recursive_Call (Flag143)
1473 -- Present in procedures. Set if a direct parameterless recursive call
1474 -- is detected while analyzing the body. Used to activate some error
1475 -- checks for infinite recursion.
1477 -- Has_Size_Clause (Flag29)
1478 -- Present in entities for types and objects. Set if a size clause is
1479 -- present for the entity. Used to prevent multiple Size clauses for a
1480 -- given entity. Note that it is always initially cleared for a derived
1481 -- type, even though the Size for such a type is inherited from a Size
1482 -- clause given for the parent type.
1484 -- Has_Small_Clause (Flag67)
1485 -- Present in ordinary fixed point types (but not subtypes). Indicates
1486 -- that a small clause has been given for the entity. Used to prevent
1487 -- multiple Small clauses for a given entity. Note that it is always
1488 -- initially cleared for a derived type, even though the Small for such
1489 -- a type is inherited from a Small clause given for the parent type.
1491 -- Has_Specified_Layout (Flag100) [implementation base type only]
1492 -- Present in all type entities. Set for a record type or subtype if
1493 -- the record layout has been specified by a record representation
1494 -- clause. Note that this differs from the flag Has_Record_Rep_Clause
1495 -- in that it is inherited by a derived type. Has_Record_Rep_Clause is
1496 -- used to indicate that the type is mentioned explicitly in a record
1497 -- representation clause, and thus is not inherited by a derived type.
1498 -- This flag is always False for non-record types.
1500 -- Has_Storage_Size_Clause (Flag23) [implementation base type only]
1501 -- Present in task types and access types. It is set if a Storage_Size
1502 -- clause is present for the type. Used to prevent multiple clauses for
1503 -- one type. Note that this flag is initially cleared for a derived type
1504 -- even though the Storage_Size for such a type is inherited from a
1505 -- Storage_Size clause given for the parent type. Note that in the case
1506 -- of access types, this flag is present only in the root type, since a
1507 -- storage size clause cannot be given to a derived type.
1509 -- Has_Subprogram_Descriptor (Flag93)
1510 -- This flag is set on entities for which zero-cost exception subprogram
1511 -- descriptors can be generated (subprograms and library level package
1512 -- declarations and bodies). It indicates that a subprogram descriptor
1513 -- has been generated, and is used to suppress generation of multiple
1514 -- descriptors (e.g. when instantiating generic bodies).
1516 -- Has_Task (Flag30) [base type only]
1517 -- Present in all type entities. Set on task types themselves, and also
1518 -- (recursively) on any composite type which has a component for which
1519 -- Has_Task is set. The meaning is that an allocator of such an object
1520 -- must create the required tasks. Note that the flag is not set on
1521 -- access types, even if they designate an object that Has_Task.
1523 -- Has_Unchecked_Union (Flag123) [base type only]
1524 -- Present in all type entities. Set on unchecked unions themselves
1525 -- and (recursively) on any composite type which has a component for
1526 -- which Has_Unchecked_Union is set. The meaning is that a comparison
1527 -- operation for the type is not permitted. Note that the flag is not
1528 -- set on access types, even if they designate an object that has
1529 -- the flag Has_Unchecked_Union set.
1531 -- Has_Unknown_Discriminants (Flag72)
1532 -- Present in all type entities. Types can have unknown discriminants
1533 -- either from their declaration or through type derivation. The use
1534 -- of this flag exactly meets the spec in RM 3.7(26). Note that all
1535 -- class-wide types are considered to have unknown discriminants.
1536 -- Note that both Has_Discriminants and Has_Unknown_Discriminants may
1537 -- be true for a type. Class-wide types and their subtypes have
1538 -- unknown discriminants and can have declared ones as well. Private
1539 -- types declared with unknown discriminants may have a full view that
1540 -- has explicit discriminants, and both flag will be set on the partial
1541 -- view, to insure that discriminants are properly inherited in certain
1544 -- Has_Volatile_Components (Flag87) [implementation base type only]
1545 -- Present in all types and objects. Set only for an array type or
1546 -- array object if a valid pragma Volatile_Components or a valid
1547 -- pragma Atomic_Components applies to the type or object. Note that
1548 -- in the case of an object, this flag is only set on the object if
1549 -- there was an explicit pragma for the object. In other words, the
1550 -- proper test for whether an object has volatile components is to
1551 -- see if either the object or its base type has this flag set. Note
1552 -- that in the case of a type the pragma will be chained to the rep
1553 -- item chain of the first subtype in the usual manner.
1555 -- Has_Xref_Entry (Flag182)
1556 -- This flag is set if an entity has an entry in the Xref information
1557 -- generated in ali files. This is true for all source entities in the
1558 -- extended main source file. It is also true of entities in other
1559 -- packages that are referenced directly or indirectly from the main
1560 -- source file (indirect reference occurs when the main source file
1561 -- references an entity with a type reference. See package Lib.Xref
1562 -- for further details).
1564 -- Hiding_Loop_Variable (Node8)
1565 -- Present in variables. Set only if a variable of a discrete type is
1566 -- hidden by a loop variable in the same local scope, in which case
1567 -- the Hiding_Loop_Variable field of the hidden variable points to
1568 -- the E_Loop_Parameter entity doing the hiding. Used in processing
1569 -- warning messages if the hidden variable turns out to be unused
1570 -- or is referenced without being set.
1573 -- Present in all entities. Link for list of entities that have the
1574 -- same source name and that are declared in the same or enclosing
1575 -- scopes. Homonyms in the same scope are overloaded. Used for name
1576 -- resolution and for the generation of debugging information.
1578 -- Implementation_Base_Type (synthesized)
1579 -- Applies to all types. Similar to Base_Type, but never returns a
1580 -- private type when applied to a non-private type. Instead in this
1581 -- case, it always returns the Representation_Type of the base type
1582 -- in this case, so that we still have a concrete type. Note: it is
1583 -- allowed to apply Implementation_Base_Type to other than a type,
1584 -- in which case it simply returns the entity unchanged.
1586 -- In_Package_Body (Flag48)
1587 -- Set on the entity that denotes the package (the defining occurrence
1588 -- of the package declaration) while analyzing and expanding the package
1589 -- body. Reset on completion of analysis/expansion.
1591 -- In_Private_Part (Flag45)
1592 -- Present in package entities. Flag is set to indicate that the
1593 -- private part is being analyzed. The flag is reset at the end of the
1594 -- package declaration.
1596 -- Inner_Instances (Elist23)
1597 -- Present in generic units. Contains element list of units that are
1598 -- instantiated within the given generic. Used to diagnose circular
1601 -- Interface_Name (Node21)
1602 -- Present in exceptions, functions, procedures, variables, constants,
1603 -- and packages. Set to Empty unless an export, import, or interface
1604 -- name pragma has explicitly specified an external name, in which
1605 -- case it references an N_String_Literal node for the specified
1606 -- exteral name. In the case of exceptions, the field is set by
1607 -- Import_Exception/Export_Exception (which can be used in OpenVMS
1608 -- versions only). Note that if this field is Empty, and Is_Imported
1609 -- or Is_Exported is set, then the default interface name is the name
1610 -- of the entity, cased in a manner that is appropriate to the system
1611 -- in use. Note that Interface_Name is ignored if an address clause
1612 -- is present (since it is meaningless in this case).
1614 -- An additional special case usage of this field is in JGNAT for
1615 -- E_Component and E_Discriminant. JGNAT allows these entities to
1616 -- be imported by specifying pragma Import within a component's
1617 -- containing record definition. This supports interfacing to
1618 -- object fields defined within Java classes, and such pragmas
1619 -- are generated by the jvm2ada binding generator tool whenever
1620 -- it processes classes with public object fields. A pragma Import
1621 -- for a component can define the External_Name of the imported
1622 -- Java field (which is generally needed, because Java names are
1626 -- Present in packages and types. Set when analyzing a use clause for
1627 -- the corresponding entity. Reset at end of corresponding declarative
1628 -- part. The flag on a type is also used to determine the visibility of
1629 -- the primitive operators of the type.
1631 -- Is_Abstract (Flag19)
1632 -- Present in all types, and also for functions and procedures. Set
1633 -- for abstract types and abstract subprograms.
1635 -- Is_Access_Constant (Flag69)
1636 -- Present in access types and subtypes. Indicates that the keyword
1637 -- constant was present in the access type definition.
1639 -- Is_Access_Type (synthesized)
1640 -- Applies to all entities, true for access types and subtypes
1642 -- Is_Aliased (Flag15)
1643 -- Present in objects whose declarations carry the keyword aliased,
1644 -- and on record components that have the keyword.
1646 -- Is_Always_Inlined (synthesized)
1647 -- Present in subprograms. True if there is a pragma Inline_Always for
1650 -- Is_AST_Entry (Flag132)
1651 -- Present in entry entities. Set if a valid pragma AST_Entry applies
1652 -- to the entry. This flag can only be set in OpenVMS versions of GNAT.
1653 -- Note: we also allow the flag to appear in entry families, but given
1654 -- the current implementation of the pragma AST_Entry, this flag will
1655 -- always be False in entry families.
1657 -- Is_Atomic (Flag85)
1658 -- Present in all type entities, and also in constants, components and
1659 -- variables. Set if a pragma Atomic or Shared applies to the entity.
1660 -- In the case of private and incomplete types, this flag is set in
1661 -- both the partial view and the full view.
1663 -- Is_Array_Type (synthesized)
1664 -- Applies to all entities, true for array types and subtypes
1666 -- Is_Asynchronous (Flag81)
1667 -- Present in all type entities and in procedure entities. Set
1668 -- if a pragma Asynchronous applies to the entity.
1670 -- Is_Bit_Packed_Array (Flag122) [implementation base type only]
1671 -- Present in all entities. This flag is set for a packed array
1672 -- type that is bit packed (i.e. the component size is known by the
1673 -- front end and is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed
1674 -- is always set if Is_Bit_Packed_Array is set, but it is possible for
1675 -- Is_Packed to be set without Is_Bit_Packed_Array for the case of an
1676 -- array having one or more index types that are enumeration types
1677 -- with non-standard enumeration representations.
1679 -- Is_Boolean_Type (synthesized)
1680 -- Applies to all entities, true for boolean types and subtypes,
1681 -- i.e. Standard.Boolean and all types ultimately derived from it.
1683 -- Is_By_Copy_Type (synthesized)
1684 -- Applies to all type entities. Returns true if the entity is
1685 -- a by copy type (RM 6.2(3)).
1687 -- Is_By_Reference_Type (synthesized)
1688 -- Applies to all type entities. True if the type is required to
1689 -- be passed by reference, as defined in (RM 6.2(4-9)).
1691 -- Is_Called (Flag102)
1692 -- Present in subprograms. Returns true if the subprogram is called
1693 -- in the unit being compiled or in a unit in the context. Used for
1696 -- Is_Character_Type (Flag63)
1697 -- Present in all entities, true for character types and subtypes,
1698 -- i.e. enumeration types that have at least one character literal.
1700 -- Is_Child_Unit (Flag73)
1701 -- Present in all entities. Set only for defining entities of program
1702 -- units that are child units (but False for subunits).
1704 -- Is_Class_Wide_Type (synthesized)
1705 -- Applies to all entities, true for class wide types and subtypes
1707 -- Is_Class_Wide_Equivalent_Type (Flag35)
1708 -- Present in record types and subtypes. Set to True, if the type acts
1709 -- as a class-wide equivalent type, i.e. the Equivalent_Type field of
1710 -- some class-wide subtype entity references this record type.
1712 -- Is_Compilation_Unit (Flag149)
1713 -- Present in all entities. Set if the entity is a package or subprogram
1714 -- entity for a compilation unit other than a subunit (since we treat
1715 -- subunits as part of the same compilation operation as the ultimate
1716 -- parent, we do not consider them to be separate units for this flag).
1718 -- Is_Completely_Hidden (Flag103)
1719 -- A flag set on an E_Discriminant entity. This flag can be set only
1720 -- for girder discriminants of untagged types. When set, the entity
1721 -- is a girder discriminant of a derived untagged type which is not
1722 -- directly visible in the derived type because the derived type or
1723 -- one of its ancestors have renamed the discriminants in the root
1724 -- type. Note that there are girder discriminants which are not
1725 -- Completely_Hidden (e.g. the discriminants of a root type).
1727 -- Is_Composite_Type (synthesized)
1728 -- Applies to all entities, true for all composite types and
1729 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
1730 -- not both) is true of any type.
1732 -- Is_Concurrent_Record_Type (Flag20)
1733 -- Present in record types and subtypes. Set if the type was created
1734 -- by the expander to represent a task or protected type. For every
1735 -- concurrent type, such as record type is constructed, and task and
1736 -- protected objects are instances of this record type at runtime
1737 -- (Gigi will replace declarations of the concurrent type using the
1738 -- declarations of the corresponding record type). See package Exp_Ch9
1739 -- for further details.
1741 -- Is_Concurrent_Type (synthesized)
1742 -- Applies to all entities, true for task types and subtypes and
1743 -- for protected types and subtypes.
1745 -- Is_Constrained (Flag12)
1746 -- Present in types or subtypes which may have index, discriminant
1747 -- or range constraint (i.e. array types and subtypes, record types
1748 -- and subtypes, string types and subtypes, and all numeric types).
1749 -- Set if the type or subtype is constrained.
1751 -- Is_Constr_Subt_For_U_Nominal (Flag80)
1752 -- Present in all types and subtypes. Set true only for the constructed
1753 -- subtype of an object whose nominal subtype is unconstrained. Note
1754 -- that the constructed subtype itself will be constrained.
1756 -- Is_Constr_Subt_For_UN_Aliased (Flag141)
1757 -- This flag can only be set if Is_Constr_Subt_For_U_Nominal is set. It
1758 -- indicates that in addition the object concerned is aliased. This flag
1759 -- is used by Gigi to determine whether a template must be constructed.
1761 -- Is_Constructor (Flag76)
1762 -- Present in function and procedure entities. Set if a pragma
1763 -- CPP_Constructor applies to the subprogram.
1765 -- Is_Controlled (Flag42) [base type only]
1766 -- Present in all type entities. Indicates that the type is controlled,
1767 -- i.e. is either a descendant of Ada.Finalization.Controlled or of
1768 -- Ada.Finalization.Limited_Controlled.
1770 -- Is_Controlling_Formal (Flag97)
1771 -- Present in all Formal_Kind entity. Marks the controlling parameters
1772 -- of dispatching operations.
1774 -- Is_CPP_Class (Flag74)
1775 -- Present in all type entities, set only for tagged and untagged
1776 -- record types to which the pragma CPP_Class has been applied.
1778 -- Is_Decimal_Fixed_Point_Type (synthesized)
1779 -- Applies to all type entities, true for decimal fixed point
1780 -- types and subtypes.
1782 -- Is_Derived_Type (synthesized)
1783 -- Applies to all type entities. Determine if given entity is a
1786 -- Is_Discrete_Type (synthesized)
1787 -- Applies to all entities, true for all discrete types and subtypes
1789 -- Is_Discrete__Or_Fixed_Point_Type (synthesized)
1790 -- Applies to all entities, true for all discrete types and subtypes
1791 -- and all fixed-point types and subtypes.
1793 -- Is_Discrim_SO_Function (Flag176)
1794 -- Present in all entities, set only in E_Function entities that Layout
1795 -- creates to compute discriminant-dependent dynamic size/offset values.
1797 -- Is_Dispatching_Operation (Flag6)
1798 -- Present in all entities. Set true for procedures, functions,
1799 -- generic procedures and generic functions if the corresponding
1800 -- operation is dispatching.
1802 -- Is_Dynamic_Scope (synthesized)
1803 -- Applies to all Entities. Returns True if the entity is a dynamic
1804 -- scope (i.e. a block, a subprogram a task_type or an entry).
1806 -- Is_Elementary_Type (synthesized)
1807 -- Applies to all entities, true for all elementary types and
1808 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
1809 -- not both) is true of any type.
1811 -- Is_Eliminated (Flag124)
1812 -- Present in type entities, subprogram entities, and object entities.
1813 -- Indicates that the corresponding entity has been eliminated by use
1814 -- of pragma Eliminate. Also used to mark subprogram entities whose
1815 -- declaration and body are within unreachable code that is removed.
1817 -- Is_Enumeration_Type (synthesized)
1818 -- Present in all entities, true for enumeration types and subtypes
1820 -- Is_Entry (synthesized)
1821 -- Applies to all entities, True only for entry and entry family
1822 -- entities and False for all other entity kinds.
1824 -- Is_Entry_Formal (Flag52)
1825 -- Present in all entities. Set only for entry formals (which can
1826 -- only be in, in-out or out parameters). This flag is used to speed
1827 -- up the test for the need to replace references in Exp_Ch2.
1829 -- Is_Exported (Flag99)
1830 -- Present in all entities. Set if the entity is exported. For now we
1831 -- only allow the export of constants, exceptions, functions, procedures
1832 -- and variables, but that may well change later on. Exceptions can only
1833 -- be exported in the OpenVMS and Java VM implementations of GNAT.
1835 -- Is_First_Subtype (Flag70)
1836 -- Present in all entities. True for first subtypes (RM 3.2.1(6)),
1837 -- i.e. the entity in the type declaration that introduced the type.
1838 -- This may be the base type itself (e.g. for record declarations and
1839 -- enumeration type declarations), or it may be the first subtype of
1840 -- an anonymous base type (e.g. for integer type declarations or
1841 -- constrained array declarations).
1843 -- Is_Fixed_Point_Type (synthesized)
1844 -- Applies to all entities, true for decimal and ordinary fixed
1845 -- point types and subtypes
1847 -- Is_Floating_Point_Type (synthesized)
1848 -- Applies to all entities, true for float types and subtypes
1850 -- Is_Formal (synthesized)
1851 -- Applies to all entities, true for IN, IN OUT and OUT parameters
1853 -- Is_Formal_Subprogram (Flag111)
1854 -- Defined on all entities, true for generic formal subprograms.
1856 -- Is_For_Access_Subtype (Flag118)
1857 -- Present in E_Private_Subtype and E_Record_Subtype entities.
1858 -- Means the sole purpose of the type is to be designated by an
1859 -- Access_Subtype and hence should not be expanded into components
1860 -- because the type may not have been found or frozen yet.
1862 -- Is_Frozen (Flag4)
1863 -- Present in all type entities. Set if the type has been frozen.
1865 -- Is_Generic_Actual_Type (Flag94)
1866 -- Present in the subtype declaration that renames the generic formal
1867 -- as a subtype of the actual. Guarantees that the subtype is not static
1868 -- within the instance.
1870 -- Is_Generic_Instance (Flag130)
1871 -- Present in all entities. Set to indicate that the entity is an
1872 -- instance of a generic unit.
1874 -- Is_Generic_Subprogram (synthesized)
1875 -- Applies to all entities. Yields True for a generic subprogram
1876 -- (generic function, generic subprogram), False for all other entities.
1878 -- Is_Generic_Type (Flag13)
1879 -- Present in all types and subtypes. Set for types which are generic
1880 -- formal types. Such types have an Ekind that corresponds to their
1881 -- classification, so the Ekind cannot be used to identify generic types.
1883 -- Is_Generic_Unit (synthesized)
1884 -- Applies to all entities. Yields True for a generic unit (generic
1885 -- package, generic function, generic procedure), and False for all
1888 -- Is_Hidden (Flag57)
1889 -- Present in all entities. Set true for all entities declared in the
1890 -- private part or body of a package. Also marks generic formals of a
1891 -- formal package declared without a box. For library level entities,
1892 -- this flag is set if the entity is not publicly visible.
1894 -- Is_Hidden_Open_Scope (Flag171)
1895 -- Present in all entities. Set true for a scope that contains the
1896 -- instantiation of a child unit, and whose entities are not visible
1897 -- during analysis of the instance.
1899 -- Is_Immediately_Visible (Flag7)
1900 -- Present in all entities. Set if entity is immediately visible, i.e.
1901 -- is defined in some currently open scope (RM 8.3(4)).
1903 -- Is_Imported (Flag24)
1904 -- Present in all entities. Set if the entity is imported. For now we
1905 -- only allow the import of exceptions, functions, procedures, packages.
1906 -- and variables. Exceptions can only be imported in the OpenVMS and
1907 -- Java VM implementations of GNAT. Packages and types can only be
1908 -- imported in the Java VM implementation.
1910 -- Is_Incomplete_Or_Private_Type (synthesized)
1911 -- Applies to all entities, true for private and incomplete types
1913 -- Is_Indefinite_Subtype (synthesized)
1914 -- Applies to all entities for types and subtypes. Determines if given
1915 -- entity is an unconstrained array type or subtype, a discriminated
1916 -- record type or subtype with no initial discriminant values or a
1917 -- class wide type or subtype.
1919 -- Is_Inlined (Flag11)
1920 -- Present in all entities. Set for functions and procedures which are
1921 -- to be inlined. For subprograms created during expansion, this flag
1922 -- may be set directly by the expander to request inlining. Also set
1923 -- for packages that contain inlined subprograms, whose bodies must be
1924 -- be compiled. Is_Inlined is also set on generic subprograms and is
1925 -- inherited by their instances. It is also set on the body entities
1926 -- of inlined subprograms. See also Has_Pragma_Inline.
1928 -- Is_Instantiated (Flag126)
1929 -- Present in generic packages and generic subprograms. Set if the unit
1930 -- is instantiated from somewhere in the extended main source unit. This
1931 -- flag is used to control warnings about the unit being uninstantiated.
1932 -- Also set in a package that is used as an actual for a generic package
1933 -- formal in an instantiation. Also set on a parent instance, in the
1934 -- instantiation of a child, which is implicitly declared in the parent.
1936 -- Is_Integer_Type (synthesized)
1937 -- Applies to all entities, true for integer types and subtypes
1939 -- Is_Internal (Flag17)
1940 -- Present in all entities. Set to indicate an entity created during
1941 -- semantic processing (e.g. an implicit type). Need more documentation
1944 -- Is_Interrupt_Handler (Flag89)
1945 -- Present in procedures. Set if a pragma Interrupt_Handler applies
1946 -- to the procedure. The procedure must be parameterless, and on all
1947 -- targets except AAMP it must be a protected procedure.
1949 -- Is_Intrinsic_Subprogram (Flag64)
1950 -- Present in functions and procedures. It is set if a valid pragma
1951 -- Interface or Import is present for this subprogram specifying pragma
1952 -- Intrinsic. Valid means that the name and profile of the subprogram
1953 -- match the requirements of one of the recognized intrinsic subprograms
1954 -- (see package Sem_Intr for details). Note: the value of Convention for
1955 -- such an entity will be set to Convention_Intrinsic, but it is the
1956 -- setting of Is_Intrinsic_Subprogram, NOT simply having convention set
1957 -- to intrinsic, which causes intrinsic code to be generated.
1959 -- Is_Itype (Flag91)
1960 -- Present in all entities, set for Itypes. If it is set, then the
1961 -- declaration for the type does not appear explicitly in the tree.
1962 -- Instead gigi will elaborate the type when it is first used.
1963 -- Has_Delayed_Freeze can be set for Itypes, and the meaning is that
1964 -- the first use (the one which causes the type to be defined) will
1965 -- be the freeze node. Note that an important restriction on Itypes
1966 -- is that the first use of such a type (the one that causes it to be
1967 -- defined) must be in the same scope as the type.
1969 -- Is_Known_Non_Null (Flag37)
1970 -- Present in all entities. Relevant (and can be set True) only for
1971 -- objects of an access type. It is set if the object is currently
1972 -- known to have a non-null value (meaning that no access checks
1973 -- are needed). The indication can for example come from assignment
1974 -- of an access parameter or an allocator.
1976 -- Note: this flag is set according to the sequential flow of the
1977 -- program, watching the current value of the variable. However,
1978 -- this processing can miss cases of changing the value of an aliased
1979 -- or constant object, so even if this flag is set, it should not
1980 -- be believed if the variable is aliased or volatile. It would
1981 -- be a little neater to avoid the flag being set in the first
1982 -- place in such cases, but that's trickier, and there is only
1983 -- one place that tests the value anyway.
1985 -- The flag is dynamically set and reset as semantic analysis and
1986 -- expansion proceeds. Its value is meaningless once the tree is
1987 -- fully constructed, since it simply indicates the last state.
1988 -- Thus this flag has no meaning to the back end.
1990 -- Is_Known_Valid (Flag170)
1991 -- Present in all entities. Relevant for types (and subtype) and
1992 -- for objects (and enumeration literals) of a discrete type.
1994 -- The purpose of this flag is to implement the requirement stated
1995 -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
1996 -- values may not cause programs to become erroneous. See the function
1997 -- Exp_Util.Expr_Known_Valid for further details. Note that the setting
1998 -- is conservative, in the sense that if the flag is set, it must be
1999 -- right. If the flag is not set, nothing is known about the validity.
2001 -- For enumeration literals, the flag is always set, since clearly
2002 -- an enumeration literal represents a valid value. Range checks
2003 -- where necessary will ensure that this valid value is appropriate.
2005 -- For objects, the flag indicates the state of knowledge about the
2006 -- current value of the object. This may be modified during expansion,
2007 -- and thus the final value is not relevant to gigi.
2009 -- For types and subtypes, the flag is set if all possible bit patterns
2010 -- of length Object_Size (i.e. Esize of the type) represent valid values
2011 -- of the type. In general for such tytpes, all values are valid, the
2012 -- only exception being the case where an object of the type has an
2013 -- explicit size that is greater than Object_Size.
2015 -- For non-discrete objects, the setting of the Is_Known_Valid flag is
2016 -- not defined, and is not relevant, since the considerations of the
2017 -- requirement in (RM 13.9.1(9-11)) do not apply.
2019 -- The flag is dynamically set and reset as semantic analysis and
2020 -- expansion proceeds. Its value is meaningless once the tree is
2021 -- fully constructed, since it simply indicates the last state.
2022 -- Thus this flag has no meaning to the back end.
2024 -- Is_Limited_Composite (Flag106)
2025 -- Present in all entities. True for composite types that have a
2026 -- limited component. Used to enforce the rule that operations on
2027 -- the composite type that depend on the full view of the component
2028 -- do not become visible until the immediate scope of the composite
2029 -- type itself (RM 7.3.1 (5)).
2031 -- Is_Limited_Record (Flag25)
2032 -- Present in all entities. Set to true for record (sub)types if the
2033 -- record is declared to be limited. Note that this flag is not set
2034 -- simply because some components of the record are limited.
2036 -- Is_Limited_Type (synthesized)
2037 -- Applies to all entities. True if entity is a limited type (limited
2038 -- private type, task type, protected type, composite containing a
2039 -- limited component, or a subtype of any of these types).
2041 -- Is_Machine_Code_Subprogram (Flag137)
2042 -- Present in subprogram entities. Set to indicate that the subprogram
2043 -- is a machine code subprogram (i.e. its body includes at least one
2044 -- code statement). Also indicates that all necessary semantic checks
2045 -- as required by RM 13.8(3) have been performed.
2047 -- Is_Modular_Integer_Type (synthesized)
2048 -- Applies to all entities. True if entity is a modular integer type
2050 -- Is_Non_Static_Subtype (Flag109)
2051 -- This flag is present in all type and subtype entities. It is set in
2052 -- some (but not all) cases in which a subtype is known to be non-static.
2053 -- Before this flag was added, the computation of whether a subtype was
2054 -- static was entirely synthesized, by looking at the bounds, and the
2055 -- immediate subtype parent. However, this method does not work for some
2056 -- Itypes that have no parent set (and the only way to find the immediate
2057 -- subtype parent is to go through the tree). For now, this flay is set
2058 -- conservatively, i.e. if it is set then for sure the subtype is non-
2059 -- static, but if it is not set, then the type may or may not be static.
2060 -- Thus the test for a static subtype is that this flag is clear AND
2061 -- that the bounds are static AND that the parent subtype (if available
2062 -- to be tested) is static. Eventually we should make sure this flag
2063 -- is always set right, at which point, these comments can be removed,
2064 -- and the tests for static subtypes greatly simplified.
2066 -- Is_Null_Init_Proc (Flag178)
2067 -- Present in procedure entities. Set for generated init proc procedures
2068 -- (used to initialize composite types), if the code for the procedure
2069 -- is null (i.e. is a return and nothing else). Such null initialization
2070 -- procedures are generated in case some client is compiled using the
2071 -- Initialize_Scalars pragma, generating a call to this null procedure,
2072 -- but there is no need to call such procedures within a compilation
2073 -- unit, and this flag is used to suppress such calls.
2075 -- Is_Numeric_Type (synthesized)
2076 -- Applies to all entities, true for all numeric types and subtypes
2077 -- (integer, fixed, float).
2079 -- Is_Object (synthesized)
2080 -- Applies to all entities, true for entities representing objects,
2081 -- including generic formal parameters.
2083 -- Is_Optional_Parameter (Flag134)
2084 -- Present in parameter entities. Set if the parameter is specified as
2085 -- optional by use of a First_Optional_Parameter argument to one of the
2086 -- extended Import pragmas. Can only be set for OpenVMS versions of GNAT.
2088 -- Is_Ordinary_Fixed_Point_Type (synthesized)
2089 -- Applies to all entities, true for ordinary fixed point types
2092 -- Is_Overriding_Operation (Flag39)
2093 -- Present in subprograms. Set if the subprogram is a primitive
2094 -- operation of a derived type, that overrides an inherited operation.
2096 -- Is_Package (synthesized)
2097 -- Applies to all entities. True for packages and generic packages.
2098 -- False for all other entities.
2100 -- Is_Package_Body_Entity (Flag160)
2101 -- Present in all entities. Set for entities defined at the top level
2102 -- of a package body. Used to control externally generated names.
2104 -- Is_Packed (Flag51) [implementation base type only]
2105 -- Present in all type entities. This flag is set only for record and
2106 -- array types which have a packed representation. There are three
2107 -- cases which cause packing:
2109 -- 1. Explicit use of pragma Pack for an array of package components
2110 -- 2. Explicit use of pragma Pack to pack a record
2111 -- 4. Setting Component_Size of an array to a bit-packable value
2112 -- 3. Indexing an array with a non-standard enumeration type.
2114 -- For records, Is_Packed is always set if Has_Pack_Pragma is set,
2115 -- and can also be set on its own in a derived type which inherited
2116 -- its packed status.
2118 -- For arrays, Is_Packed is set if an array is bit packed (i.e. the
2119 -- component size is known at compile time and is 1-7, 9-15 or 17-31),
2120 -- or if the array has one or more index types that are enumeration
2121 -- types with non-standard representations (in GNAT, we store such
2122 -- arrays compactly, using the Pos of the enumeration type value).
2124 -- As for the case of records, Is_Packed can be set on its own for a
2125 -- derived type, with the same dual before/after freeze meaning.
2126 -- Is_Packed can also be set as the result of an explicit component
2127 -- size clause that specifies an appropriate component size.
2129 -- In the bit packed array case, Is_Bit_Packed_Array will be set in
2130 -- the bit packed case once the array type is frozen.
2132 -- Before an array type is frozen, Is_Packed will always be set if
2133 -- Has_Pack_Pragma is set. Before the freeze point, it is not possible
2134 -- to know the component size, since the component type is not frozen
2135 -- until the array type is frozen. Thus Is_Packed for an array type
2136 -- before it is frozen means that packed is required. Then if it turns
2137 -- out that the component size is not suitable for bit packing, the
2138 -- Is_Packed flag gets turned off.
2140 -- Is_Packed_Array_Type (Flag138)
2141 -- Present in all entities. This flag is set on the entity for the type
2142 -- used to implement a packed array (either a modular type, or a subtype
2143 -- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
2144 -- if the type appears in the Packed_Array_Type field of some other type
2145 -- entity. It is used by Gigi to activate the special processing for such
2146 -- types (unchecked conversions that would not otherwise be allowed are
2147 -- allowed for such types). If the Is_Packed_Array_Type flag is set in
2148 -- an entity, then the Original_Array_Type field of this entity points
2149 -- to the original array type for which this is the packed array type.
2151 -- Is_Potentially_Use_Visible (Flag9)
2152 -- Present in all entities. Set if entity is potentially use visible,
2153 -- i.e. it is defined in a package that appears in a currently active
2154 -- use clause (RM 8.4(8)). Note that potentially use visible entities
2155 -- are not necessarily use visible (RM 8.4(9-11)).
2157 -- Is_Preelaborated (Flag59)
2158 -- Present in all entities, set in E_Package and E_Generic_Package
2159 -- entities to which a pragma Preelaborate is applied, and also in
2160 -- all entities within such packages. Note that the fact that this
2161 -- flag is set does not necesarily mean that no elaboration code is
2162 -- generated for the package.
2164 -- Is_Private_Composite (Flag107)
2165 -- Present in composite types that have a private component. Used to
2166 -- enforce the rule that operations on the composite type that depend
2167 -- on the fulll view of the component, do not become visible until the
2168 -- immediate scope of the composite type itself (7.3.1 (5)). Both this
2169 -- flag and Is_Limited_Composite are needed.
2171 -- Is_Private_Descendant (Flag53)
2172 -- Present in entities that can represent library units (packages,
2173 -- functions, procedures). Set if the library unit is itself a private
2174 -- child unit, or if it is the descendent of a private child unit.
2176 -- Is_Private_Type (synthesized)
2177 -- Applies to all entities, true for private types and subtypes,
2178 -- as well as for record with private types as subtypes
2180 -- Is_Protected_Type (synthesized)
2181 -- Applies to all entities, true for protected types and subtypes
2183 -- Is_Psected (Flag153)
2184 -- Present in entities for objects, true if a valid Psect_Object
2185 -- pragma applies to the object. Used to detect duplicate pragmas.
2187 -- Is_Public (Flag10)
2188 -- Present in all entities. Set to indicate that an entity defined in
2189 -- one compilation unit can be referenced from other compilation units.
2190 -- If this reference causes a reference in the generated variable, for
2191 -- example in the case of a variable name, then Gigi will generate an
2192 -- appropriate external name for use by the linker.
2194 -- Is_Protected_Private (synthesized)
2195 -- Applies to a record component. Returns true if this component
2196 -- is used to represent a private declaration of a protected type.
2198 -- Is_Protected_Record_Type (synthesized)
2199 -- Applies to all entities, true if Is_Concurrent_Record_Type
2200 -- Corresponding_Concurrent_Type is a protected type.
2203 -- Present in all entities. Set in all entities of a unit to which a
2204 -- pragma Pure is applied, and also set for the entity of the unit
2205 -- itself. In addition, this flag may be set for any other functions
2206 -- or procedures that are known to be side effect free, so in the case
2207 -- of subprograms, the Is_Pure flag may be used by the optimizer to
2208 -- imply that it can assume freedom from side effects (other than those
2209 -- resulting from assignment to out parameters, or to objects designated
2210 -- by access parameters).
2212 -- Is_Real_Type (synthesized)
2213 -- Applies to all entities, true for real types and subtypes
2215 -- Is_Record_Type (synthesized)
2216 -- Applies to all entities, true for record types and subtypes,
2217 -- includes class-wide types and subtypes (which are also records)
2219 -- Is_Remote_Call_Interface (Flag62)
2220 -- Present in all entities, set in E_Package and E_Generic_Package
2221 -- entities to which a pragma Remote_Call_Interace is applied, and
2222 -- also in all entities within such packages.
2224 -- Is_Remote_Types (Flag61)
2225 -- Present in all entities, set in E_Package and E_Generic_Package
2226 -- entities to which a pragma Remote_Types is applied, and also in
2227 -- all entities within such packages.
2229 -- Is_Renaming_Of_Object (Flag112)
2230 -- Present in all entities, set only for a variable or constant for
2231 -- which the Renamed_Object field is non-empty and for which the
2232 -- renaming is handled by the front end, by macro substitution of
2233 -- a copy of the (evaluated) name tree whereever the variable is used.
2235 -- Is_Return_By_Reference_Type (synthesized)
2236 -- Applies to all type entities. True if the type is required to
2237 -- be returned by reference, as defined in 6.5(11-16).
2239 -- Is_Scalar_Type (synthesized)
2240 -- Applies to all entities, true for scalar types and subtypes
2242 -- Is_Shared_Passive (Flag60)
2243 -- Present in all entities, set in E_Package and E_Generic_Package
2244 -- entities to which a pragma Shared_Passive is applied, and also in
2245 -- all entities within such packages.
2247 -- Is_Statically_Allocated (Flag28)
2248 -- Present in all entities. This can only be set True for exception,
2249 -- variable, constant, and type/subtype entities. If the flag is set,
2250 -- then the variable or constant must be allocated statically rather
2251 -- than on the local stack frame. For exceptions, the meaning is that
2252 -- the exception data should be allocated statically (and indeed this
2253 -- flag is always set for exceptions, since exceptions do not have
2254 -- local scope). For a type, the meaning is that the type must be
2255 -- elaborated at the global level rather than locally. No type marked
2256 -- with this flag may depend on a local variable, or on any other type
2257 -- which does not also have this flag set to True. For a variable or
2258 -- or constant, if the flag is set, then the type of the object must
2259 -- either be declared at the library level, or it must also have the
2260 -- flag set (since to allocate the oject statically, its type must
2261 -- also be elaborated globally).
2263 -- Is_Subprogram (synthesized)
2264 -- Applies to all entities, true for bodies of functions, procedures
2267 -- Is_String_Type (synthesized)
2268 -- Applies to all type entities. Determines if the given type is a
2269 -- string type, i.e. it is directly a string type or string subtype,
2270 -- or a string slice type, or an array type with one dimension and a
2271 -- component type that is a character type.
2274 -- Present in E_Component. For regular tagged type this flag is set on
2275 -- the tag component (whose name is Name_uTag) and for CPP_Class tagged
2276 -- types, this flag marks the pointer to the main vtable (i.e. the one
2277 -- to be extended by derivation)
2279 -- Is_Tagged_Type (Flag55)
2280 -- Present in all entities, true for an entity for a tagged type.
2282 -- Is_Task_Record_Type (synthesized)
2283 -- Applies to all entities, true if Is_Concurrent_Record_Type
2284 -- Corresponding_Concurrent_Type is a task type.
2286 -- Is_Task_Type (synthesized)
2287 -- Applies to all entities, true for task types and subtypes
2289 -- Is_Thread_Body (Flag77)
2290 -- Applies to subprogram entities. Set if a valid Thread_Body pragma
2291 -- applies to this subprogram, which is thus a thread body.
2293 -- Is_True_Constant (Flag163)
2294 -- This flag is set in constants and variables which have an initial
2295 -- value specified but which are never assigned, partially or in the
2296 -- whole. For variables, it means that the variable was initialized
2297 -- but never modified, and hence can be treated as a constant by the
2298 -- code generator. For a constant, it means that the constant was not
2299 -- modified by generated code (e.g. to set a discriminant in an init
2300 -- proc). Assignments by user or generated code will reset this flag.
2302 -- Note: there is one situation in which the back end does not permit
2303 -- this flag to be set, even if no assignments are generated. This is
2304 -- the case of an object of a record or array type which is initialized
2305 -- with an aggregate, and is itself used as the expression initializing
2306 -- an atomic object, or the right hand side of an assignment to an atomic
2307 -- object. In this case the object must not have Is_True_Constant set,
2308 -- even though no assignments are generated (the reason for this is that
2309 -- the back end must not optimize the object away, because that would
2310 -- violate the restriction on aggregates in these positions).
2312 -- Is_Type (synthesized)
2313 -- Applies to all entities, true for a type entity
2315 -- Is_Unchecked_Union (Flag117)
2316 -- Present in all entities. Set only in record types to which the
2317 -- pragma Unchecked_Union has been validly applied.
2319 -- Is_Unsigned_Type (Flag144)
2320 -- Present in all types, but can be set only for discrete and fixed-point
2321 -- type and subtype entities. This flag is only valid if the entity is
2322 -- frozen. If set it indicates that the representation is known to be
2323 -- unsigned (i.e. that no negative values appear in the range). This is
2324 -- normally just a reflection of the lower bound of the subtype or base
2325 -- type, but there is one case in which the setting is non-obvious,
2326 -- namely the case of an unsigned subtype of a signed type from which
2327 -- a further subtype is obtained using variable bounds. This further
2328 -- subtype is still unsigned, but this cannot be determined by looking
2329 -- at its bounds or the bounds of the corresponding base type.
2331 -- Is_Valued_Procedure (Flag127)
2332 -- Present in procedure entities. Set if an Import_Valued_Procedure
2333 -- or Export_Valued_Procedure pragma applies to the procedure entity.
2335 -- Is_Visible_Child_Unit (Flag116)
2336 -- Present in compilation units that are child units. Once compiled,
2337 -- child units remain chained to the entities in the parent unit, and
2338 -- a separate flag must be used to indicate whether the names are
2339 -- visible by selected notation, or not.
2341 -- Is_VMS_Exception (Flag133)
2342 -- Present in all entities. Set only for exception entities where the
2343 -- exception was specified in an Import_Exception or Export_Exception
2344 -- pragma with the VMS option for Form. See description of these pragmas
2345 -- for details. This flag can only be set in OpenVMS versions of GNAT.
2347 -- Is_Volatile (Flag16)
2348 -- Present in all type entities, and also in constants, components and
2349 -- variables. Set if a pragma Volatile applies to the entity. Also set
2350 -- if pragma Shared or pragma Atomic applies to entity. In the case of
2351 -- private or incomplete types, this flag is set in both the private
2352 -- and full view. The flag is not set reliably on private subtypes,
2353 -- and is always retrieved from the base type (but this is not a base-
2354 -- type-only attribute because it applies to other entities). Note that
2355 -- the back end should use Treat_As_Volatile, rather than Is_Volatile
2356 -- to indicate code generation requirements for volatile variables.
2357 -- Similarly, any front end test which is concerned with suppressing
2358 -- optimizations on volatile objects should test Treat_As_Volatile
2359 -- rather than testing this flag.
2361 -- Is_Wrapper_Package (synthesized)
2362 -- Present in package entities. Indicates that the package has been
2363 -- created as a wrapper for a subprogram instantiation.
2365 -- Kill_Elaboration_Checks (Flag32)
2366 -- Present in all entities. Set by the expander to kill elaboration
2367 -- checks which are known not to be needed. Equivalent in effect to
2368 -- the use of pragma Supress (Elaboration_Checks) for that entity
2369 -- except that the effect is permanent and cannot be undone by a
2370 -- subsequent pragma Unsuppress.
2372 -- Kill_Range_Checks (Flag33)
2373 -- Present in all entities. Set by the expander to kill elaboration
2374 -- checks which are known not to be needed. Equivalent in effect to
2375 -- the use of pragma Supress (Range_Checks) for that entity except
2376 -- that the result is permanent and cannot be undone by a subsequent
2377 -- pragma Unsuppress.
2379 -- Kill_Tag_Checks (Flag34)
2380 -- Present in all entities. Set by the expander to kill elaboration
2381 -- checks which are known not to be needed. Equivalent in effect to
2382 -- the use of pragma Supress (Tag_Checks) for that entity except
2383 -- that the result is permanent and cannot be undone by a subsequent
2384 -- pragma Unsuppress.
2386 -- Last_Entity (Node20)
2387 -- Present in all entities which act as scopes to which a list of
2388 -- associated entities is attached (blocks, class subtypes and types,
2389 -- entries, functions, loops, packages, procedures, protected objects,
2390 -- record types and subtypes, private types, task types and subtypes).
2391 -- Points to a the last entry in the list of associated entities chained
2392 -- through the Next_Entity field. Empty if no entities are chained.
2394 -- Limited_View (Node23)
2395 -- Present in non-generic package entities that are not instances. Bona
2396 -- fide package with the limited-view list through the first_entity and
2397 -- first_private attributes. The elements of this list are the shadow
2398 -- entities created for the types and local packages that are declared
2399 -- in a package appearing in a limited_with clause (Ada 2005: AI-50217)
2401 -- Lit_Indexes (Node15)
2402 -- Present in enumeration types and subtypes. Non-empty only for the
2403 -- case of an enumeration root type, where it contains the entity for
2404 -- the generated indexes entity. See unit Exp_Imgv for full details of
2405 -- the nature and use of this entity for implkementing the Image and
2406 -- Value attributes for the enumeration type in question.
2408 -- Lit_Strings (Node16)
2409 -- Present in enumeration types and subtypes. Non-empty only for the
2410 -- case of an enumeration root type, where it contains the entity for
2411 -- the literals string entity. See unit Exp_Imgv for full details of
2412 -- the nature and use of this entity for implementing the Image and
2413 -- Value attributes for the enumeration type in question.
2415 -- Machine_Radix_10 (Flag84)
2416 -- Present in decimal types and subtypes, set if the Machine_Radix
2417 -- is 10, as the result of the specification of a machine radix
2418 -- representation clause. Note that it is possible for this flag
2419 -- to be set without having Has_Machine_Radix_Clause True. This
2420 -- happens when a type is derived from a type with a clause present.
2422 -- Master_Id (Node17)
2423 -- Present in access types and subtypes. Empty unless Has_Task is
2424 -- set for the designated type, in which case it points to the entity
2425 -- for the Master_Id for the access type master.
2427 -- Materialize_Entity (Flag168)
2428 -- Present in all entities. Set only for constant or renamed entities
2429 -- which should be materialized for debugging purposes. In the case of
2430 -- a constant, a memory location should be allocated containing the
2431 -- value. In the case of a renaming, a memory location containing the
2432 -- renamed address should be allocated.
2434 -- Mechanism (Uint8) (returned as Mechanism_Type)
2435 -- Present in functions and non-generic formal parameters. Indicates
2436 -- the mechanism to be used for the function return or for the formal
2437 -- parameter. See separate section on passing mechanisms. This field
2438 -- is also set (to the default value of zero) in a subprogram body
2439 -- entity but not used in this context.
2441 -- Modulus (Uint17) [base type only]
2442 -- Present in modular types. Contains the modulus. For the binary
2443 -- case, this will be a power of 2, but if Non_Binary_Modulus is
2444 -- set, then it will not be a power of 2.
2446 -- Must_Be_On_Byte_Boundary (Flag183)
2447 -- Present in entities for types and subtypes. Set if objects of
2448 -- the type must always be allocated on a byte boundary (more
2449 -- accurately a storage unit boundary). The front end checks that
2450 -- component clauses respect this rule, and the back end ensures
2451 -- that record packing does not violate this rule. Currently the
2452 -- flag is set only for packed arrays longer than 64 bits.
2454 -- Needs_Debug_Info (Flag147)
2455 -- Present in all entities. Set if the entity requires debugging
2456 -- information to be generated. This is true of all entities that
2457 -- have Comes_From_Source set, and also transitively for entities
2458 -- associated with such components (e.g. their types). It is true
2459 -- for all entities in Debug_Generated_Code mode (-gnatD switch).
2460 -- This is the flag that the back end should check to determine
2461 -- whether or not to generate debugging information for an entity.
2463 -- Needs_No_Actuals (Flag22)
2464 -- Present in callable entities (subprograms, entries, access to
2465 -- subprograms) which can be called without actuals because all of
2466 -- their formals (if any) have default values. This flag simplifies the
2467 -- resolution of the syntactic ambiguity involving a call to these
2468 -- entities when the return type is an array type, and a call can be
2469 -- interpreted as an indexing of the result of the call. It is also
2470 -- used to resolve various cases of entry calls.
2472 -- Never_Set_In_Source (Flag115)
2473 -- Present in all entities, but relevant only for variables and
2474 -- parameters. This flag is set if the object is never assigned
2475 -- a value in user source code, either by assignment or by the
2476 -- use of an initial value, or by some other means.
2478 -- This flag is only for the purposes of issuing warnings, it must not
2479 -- be used by the code generator to indicate that the variable is in
2480 -- fact a constant, since some assignments in generated code do not
2481 -- count (for example, the call to an init proc to assign some but
2482 -- not all of the fields in a partially initialized record). The code
2483 -- generator should instead use the flag Is_True_Constant.
2485 -- For the purposes of this warning, the default assignment of
2486 -- access variables to null is not considered the assignment of
2487 -- of a value (so the warning can be given for code that relies
2488 -- on this initial null value, when no other value is ever set).
2490 -- In variables and out parameters, if this flag is set after full
2491 -- processing of the corresponding declarative unit, it indicates that
2492 -- the variable or parameter was never set, and a warning message can
2495 -- Note: this flag is initially set, and then cleared on encountering
2496 -- any construct that might conceivably legitimately set the value.
2497 -- Thus during the analysis of a declarative region and its associated
2498 -- statement sequence, the meaning of the flag is "not set yet", and
2499 -- once this analysis is complete the flag means "never assigned".
2501 -- Note: for variables appearing in package declarations, this flag
2502 -- is never set. That is because there is no way to tell if some
2503 -- client modifies the variable (or in the case of variables in the
2504 -- private part, if some child unit modifies the variables).
2506 -- Note: in the case of renamed objects, the flag must be set in the
2507 -- ultimate renamed object. Clients noting a possible modification
2508 -- should use the Note_Possible_Modification procedure in Sem_Util
2509 -- rather than Set_Never_Set_In_Source precisely to deal properly with
2510 -- the renaming possibility.
2512 -- Next_Component (synthesized)
2513 -- Applies to record components. Returns the next component by
2514 -- following the chain of declared entities until one is found which
2515 -- corresponds to a component (Ekind is E_Component). Any internal types
2516 -- generated from the subtype indications of the record components are
2517 -- skipped. Returns Empty if no more components.
2519 -- Next_Discriminant (synthesized)
2520 -- Applies to discriminants returned by First/Next_Discriminant.
2521 -- Returns the next language-defined (ie: perhaps non-girder)
2522 -- discriminant by following the chain of declared entities as long as
2523 -- the kind of the entity corresponds to a discriminant. Note that the
2524 -- discriminants might be the only components of the record.
2525 -- Returns Empty if there are no more.
2527 -- Next_Entity (Node2)
2528 -- Present in all entities. The entities of a scope are chained, with
2529 -- the head of the list being in the First_Entity field of the scope
2530 -- entity. All entities use the Next_Entity field as a forward pointer
2531 -- for this list, with Empty indicating the end of the list. Since this
2532 -- field is in the base part of the entity, the access routines for this
2533 -- field are in Sinfo.
2535 -- Next_Formal (synthesized)
2536 -- Applies to the entity for a formal parameter. Returns the next
2537 -- formal parameter of the subprogram or subprogram type. Returns
2538 -- Empty if there are no more formals.
2540 -- Next_Formal_With_Extras (synthesized)
2541 -- Applies to the entity for a formal parameter. Returns the next
2542 -- formal parameter of the subprogram or subprogram type. Returns
2543 -- Empty if there are no more formals. The list returned includes
2544 -- all the extra formals (see description of Extra_Formal field)
2546 -- Next_Girder_Discriminant (synthesized)
2547 -- Applies to discriminants. Set only for a discriminant returned by
2548 -- a call to First/Next_Girder_Discriminant. Returns next girder
2549 -- discriminant, if there are more (see complete description in
2550 -- First_Girder_Discriminant), or Empty if there are no more.
2552 -- Next_Index (synthesized)
2553 -- Applies to array types and subtypes and to string types and
2554 -- subtypes. Yields the next index. The first index is obtained by
2555 -- using the First_Index attribute, and then subsequent indexes are
2556 -- obtained by applying Next_Index to the previous index. Empty is
2557 -- returned to indicate that there are no more indexes. Note that
2558 -- unlike most attributes in this package, Next_Index applies to
2559 -- nodes for the indexes, not to entities.
2561 -- Next_Inlined_Subprogram (Node12)
2562 -- Present in subprograms. Used to chain inlined subprograms used in
2563 -- the current compilation, in the order in which they must be compiled
2564 -- by Gigi to insure that all inlinings are performed.
2566 -- Next_Literal (synthesized)
2567 -- Applies to enumeration literals, returns the next literal, or
2568 -- Empty if applied to the last literal. This is actually a synonym
2569 -- for Next, but its use is preferred in this context.
2571 -- Non_Binary_Modulus (Flag58) [base type only]
2572 -- Present in modular integer types. Set if the modulus for the type
2573 -- is other than a power of 2.
2575 -- Non_Limited_View (Node17)
2576 -- Present in incomplete types that are the shadow entities created
2577 -- when analyzing a limited_with_clause (Ada 2005: AI-50217). Points to
2578 -- the defining entity in the original declaration.
2580 -- Nonzero_Is_True (Flag162) [base type only]
2581 -- Present in enumeration types. True if any non-zero value is to be
2582 -- interpreted as true. Currently this is set true for derived Boolean
2583 -- types which have a convention of C, C++ or Fortran.
2585 -- No_Pool_Assigned (Flag131) [root type only]
2586 -- Present in access types. Set if a storage size clause applies to
2587 -- the variable with a compile time known value of zero. This flag is
2588 -- used to generate warnings if any attempt is made to allocate or free
2589 -- an instance of such an access type. This is set only in the root
2590 -- type, since derived types must have the same pool.
2592 -- No_Return (Flag113)
2593 -- Present in procedure and generic procedure entries. Indicates that
2594 -- a pragma No_Return applies to the procedure.
2596 -- Normalized_First_Bit (Uint8)
2597 -- Present in components and discriminants. Indicates the normalized
2598 -- value of First_Bit for the component, i.e. the offset within the
2599 -- lowest addressed storage unit containing part or all of the field.
2600 -- Set to No_Uint if no first bit position is assigned yet.
2602 -- Normalized_Position (Uint14)
2603 -- Present in components and discriminants. Indicates the normalized
2604 -- value of Position for the component, i.e. the offset in storage
2605 -- units from the start of the record to the lowest addressed storage
2606 -- unit containing part or all of the field.
2608 -- Normalized_Position_Max (Uint10)
2609 -- Present in components and discriminants. For almost all cases, this
2610 -- is the same as Normalized_Position. The one exception is for the case
2611 -- of a discriminated record containing one or more arrays whose length
2612 -- depends on discriminants. In this case, the Normalized_Position_Max
2613 -- field represents the maximum possible value of Normalized_Position
2614 -- assuming min/max values for discriminant subscripts in all fields.
2615 -- This is used by Layout in front end layout mode to properly computed
2616 -- the maximum size such records (needed for allocation purposes when
2617 -- there are default discriminants, and also for the 'Size value).
2619 -- No_Strict_Aliasing (Flag136) [base type only]
2620 -- Present in access types. Set to direct the back end to avoid any
2621 -- optimizations based on an assumption about the aliasing status of
2622 -- objects designated by the access type. For the case of the gcc
2623 -- back end, the effect is as though all references to objects of
2624 -- the type were compiled with -fno-strict-aliasing. This flag is
2625 -- set if an unchecked conversion with the access type as a target
2626 -- type occurs in the same source unit as the declaration of the
2627 -- access type, or if an explicit pragma No_Strict_Aliasing applies.
2629 -- Number_Dimensions (synthesized)
2630 -- Applies to array types and subtypes. Returns the number of dimensions
2631 -- of the array type or subtype as a value of type Pos.
2633 -- Number_Discriminants (synthesized)
2634 -- Applies to all types with discriminants. Yields the number of
2635 -- discriminants as a value of type Pos.
2637 -- Number_Entries (synthesized)
2638 -- Applies to concurrent types. Returns the number of entries that are
2639 -- declared within the task or protected definition for the type.
2641 -- Number_Formals (synthesized)
2642 -- Applies to subprograms and subprogram types. Yields the number of
2643 -- formals as a value of type Pos.
2645 -- Original_Access_Type (Node21)
2646 -- Present in access to subprogram types. Anonymous access to protected
2647 -- subprogram types are replaced by an occurrence of an internal access
2648 -- to subprogram type. This field links the replacement entity with the
2651 -- Original_Array_Type (Node21)
2652 -- Present in modular types and array types and subtypes. Set only
2653 -- if the Is_Packed_Array_Type flag is set, indicating that the type
2654 -- is the implementation type for a packed array, and in this case it
2655 -- points to the original array type for which this is the packed
2656 -- array implementation type.
2658 -- Object_Ref (Node17)
2659 -- Present in protected bodies. This is an implicit prival for the
2660 -- Protection object associated with a protected object. See Prival
2661 -- for further details on the use of privals.
2663 -- Original_Record_Component (Node22)
2664 -- Present in components, including discriminants. The usage depends
2665 -- on whether the record is a base type and whether it is tagged.
2667 -- In base tagged types:
2668 -- When the component is inherited in a record extension, it points
2669 -- to the original component (the entity of the ancestor component
2670 -- which is not itself inherited) otherwise it points to itself.
2671 -- Gigi uses this attribute to implement the automatic dereference in
2672 -- the extension and to apply the transformation:
2674 -- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
2676 -- In base non-tagged types:
2677 -- Always points to itself except for non-girder discriminants, where
2678 -- it points to the girder discriminant it renames.
2680 -- In subtypes (tagged and untagged):
2681 -- Points to the component in the base type.
2683 -- Packed_Array_Type (Node23)
2684 -- Present in array types and subtypes, including the string literal
2685 -- subtype case, if the corresponding type is packed (either bit packed
2686 -- or packed to eliminate holes in non-contiguous enumeration type
2687 -- index types). References the type used to represent the packed array,
2688 -- which is either a modular type for short static arrays, or an
2689 -- array of System.Unsigned. Note that in some situations (internal
2690 -- types, and references to fields of variant records), it is not
2691 -- always possible to construct this type in advance of its use. If
2692 -- Packed_Array_Type is empty, then the necessary type is declared
2693 -- on the fly for each reference to the array.
2695 -- Parameter_Mode (synthesized)
2696 -- Applies to formal parameter entities. This is a synonym for Ekind,
2697 -- used when obtaining the formal kind of a formal parameter (the result
2698 -- is one of E_[In/Out/In_Out]_Paramter)
2700 -- Parent_Subtype (Node19)
2701 -- Present in E_Record_Type. Points to the subtype to use for a
2702 -- field that references the parent record.
2704 -- Primitive_Operations (Elist15)
2705 -- Present in tagged record types and subtypes and in tagged private
2706 -- types. Points to an element list of entities for primitive operations
2707 -- for the tagged type. Not present (and not set) in untagged types (it
2708 -- is an error to reference the primitive operations field of a type
2709 -- that is not tagged).
2711 -- Private_Dependents (Elist18)
2712 -- Present in private (sub)types. Records the subtypes of the
2713 -- private type, derivations from it, and records and arrays
2714 -- with components dependent on the type.
2716 -- The subtypes are traversed when installing and deinstalling
2717 -- (the full view of) a private type in order to ensure correct
2718 -- view of the subtypes.
2720 -- Used in similar fashion for incomplete types: holds list of subtypes
2721 -- of these incomplete types that have discriminant constraints. The
2722 -- full views of these subtypes are constructed when the full view of
2723 -- the incomplete type is processed.
2725 -- In addition, if the incomplete type is the designated type in an
2726 -- access definition for an access parameter, the operation may be
2727 -- a dispatching primitive operation, which is only known when the full
2728 -- declaration of the type is seen. Subprograms that have such an
2729 -- access parameter are also placed in the list of private_dependents.
2732 -- Present in components. Used for representing private declarations
2733 -- of protected objects (private formal: by analogy to Discriminal_Link).
2734 -- Empty unless the synthesized Is_Protected_Private attribute is
2735 -- true. The entity used as a formal parameter that corresponds to
2736 -- the to the private declaration in protected operations. See
2737 -- "Private data in protected objects" for details.
2739 -- Privals_Chain (Elist23)
2740 -- Present in protected operations (subprograms and entries). Links
2741 -- all occurrences of the Privals in the body of the operation, in
2742 -- order to patch their types at the end of their expansion. See
2743 -- "Private data in protected objects" for details.
2745 -- Private_View (Node22)
2746 -- For each private type, three entities are allocated, the private view,
2747 -- the full view, and the shadow entity. The shadow entity contains a
2748 -- copy of the private view and is used for restoring the proper private
2749 -- view after a region in which the full view is visible (and is copied
2750 -- into the entity normally used for the private view during this period
2751 -- of visibility). The Private_View field is self-referential when the
2752 -- private view lives in its normal entity, but in the copy that is made
2753 -- in the shadow entity, it points to the proper location in which to
2754 -- restore the private view saved in the shadow.
2756 -- Protected_Formal (Node22)
2757 -- Present in formal parameters (in, in out and out parameters). Used
2758 -- only for formals of protected operations. References corresponding
2759 -- formal parameter in the unprotected version of the operation that
2760 -- is created during expansion.
2762 -- Protected_Body_Subprogram (Node11)
2763 -- Present in protected operations. References the entity for the
2764 -- subprogram which implements the body of the operation.
2766 -- Protected_Operation (Node23)
2767 -- Present in components. Used for representing private declarations
2768 -- of protected objects. Empty unless the synthesized attribute
2769 -- Is_Protected_Private is True. This is the entity corresponding
2770 -- to the body of the protected operation currently being analyzed,
2771 -- and which will eventually use the current Prival associated with
2772 -- this component to refer to the renaming of a private object
2773 -- component. As soon as the expander generates this renaming, this
2774 -- attribute is changed to refer to the next protected subprogram.
2775 -- See "Private data in protected objects" for details.
2777 -- Reachable (Flag49)
2778 -- Present in labels. The flag is set over the range of statements in
2779 -- which a goto to that label is legal.
2781 -- Referenced (Flag156)
2782 -- Present in all entities, set if the entity is referenced, except
2783 -- for the case of an appearence of a simple variable that is not a
2784 -- renaming, as the left side of an assignment in which case the flag
2785 -- Referenced_As_LHS is set instead.
2787 -- Referenced_As_LHS (Flag36): This flag is set instead of
2788 -- Referenced if a simple variable that is not a renaming appears as
2789 -- the left side of an assignment. The reason we distinguish this kind
2790 -- of reference is that we have a separate warning for variables that
2791 -- are only assigned and never read.
2793 -- Referenced_Object (Node10)
2794 -- Present in all type entities. Set non-Empty only for type entities
2795 -- constructed for unconstrained objects, or objects that depend on
2796 -- discriminants. Points to the expression from which the actual
2797 -- subtype of the object can be evaluated.
2799 -- Register_Exception_Call (Node20)
2800 -- Present in exception entities. When an exception is declared,
2801 -- a call is expanded to Register_Exception. This field points to
2802 -- the expanded N_Procedure_Call_Statement node for this call. It
2803 -- is used for Import/Export_Exception processing to modify the
2804 -- register call to make appropriate entries in the special tables
2805 -- used for handling these pragmas at runtime.
2807 -- Related_Array_Object (Node19)
2808 -- Present in array types and subtypes. Used only for the base type
2809 -- and subtype created for an anonymous array object. Set to point
2810 -- to the entity of the corresponding array object. Currently used
2811 -- only for type-related error messages.
2813 -- Related_Instance (Node15)
2814 -- Present in the wrapper packages created for subprogram instances.
2815 -- The internal subprogram that implements the instance is inside the
2816 -- wrapper package, but for debugging purposes its external symbol
2817 -- must correspond to the name and scope of the related instance.
2819 -- Renamed_Entity (Node18)
2820 -- Present in exceptions, packages and generic units that are defined
2821 -- by a renaming declaration. Denotes the renamed entity, or transit-
2822 -- itively the ultimate renamed entity if there is a chain of renaming
2825 -- Renamed_Object (Node18)
2826 -- Present in all objects (constants, variables, components, formal
2827 -- parameters, generic formal parameters, and loop parameters). Set
2828 -- non-Empty if the object was declared by a renaming declaration, in
2829 -- which case it references the tree node for the name of the renamed
2830 -- object. This is only possible for the variable and constant cases.
2831 -- For formal parameters, this field is used in the course of inline
2832 -- expansion, to map the formals of a subprogram into the corresponding
2833 -- actuals. For formals of a task entry, it denotes the local renaming
2834 -- that replaces the actual within the accept statement.
2835 -- The field is Empty otherwise.
2837 -- Renaming_Map (Uint9)
2838 -- Present in generic subprograms, generic packages, and their
2839 -- instances. Also present in the instances of the corresponding
2840 -- bodies. Denotes the renaming map (generic entities => instance
2841 -- entities) used to construct the instance by givin an index into
2842 -- the tables used to represent these maps. See Sem_Ch12 for further
2843 -- details. The maps for package instances are also used when the
2844 -- instance is the actual corresponding to a formal package.
2846 -- Return_Present (Flag54)
2847 -- Present in function and generic function entities. Set if the
2848 -- function contains a return statement (used for error checking).
2849 -- This flag can also be set in procedure and generic procedure
2850 -- entities (for convenience in setting it), but is only tested
2851 -- for the function case.
2853 -- Returns_By_Ref (Flag90)
2854 -- Present in function entities, to indicate that the function
2855 -- returns the result by reference, either because its return typ is a
2856 -- by-reference-type or because it uses explicitly the secondary stack.
2858 -- Reverse_Bit_Order (Flag164) [base type only]
2859 -- Present in all record type entities. Set if a valid pragma an
2860 -- attribute represention clause for Bit_Order has reversed the order
2861 -- of bits from the default value. When this flag is set, a component
2862 -- clause must specify a set of bits entirely contained in a single
2866 -- Present in all type and subtype entities. Contains the value of
2867 -- type'Size as defined in the RM. See also the Esize field and
2868 -- and the description on "Handling of Type'Size Values". A value
2869 -- of zero in this field for a non-discrete type means that
2870 -- the front end has not yet determined the size value. For the
2871 -- case of a discrete type, this field is always set by the front
2872 -- end and zero is a legitimate value for a type with one value.
2874 -- Root_Type (synthesized)
2875 -- Applies to all type entities. For class-wide types, return the root
2876 -- type of the class covered by the CW type, otherwise returns the
2877 -- ultimate derivation ancestor of the given type. This function
2878 -- preserves the view, i.e. the Root_Type of a partial view is the
2879 -- partial view of the ulimate ancestor, the Root_Type of a full view
2880 -- is the full view of the ultimate ancestor. Note that this function
2881 -- does not correspond exactly to the use of root type in the RM, since
2882 -- in the RM root type applies to a class of types, not to a type.
2884 -- Scalar_Range (Node20)
2885 -- Present in all scalar types (including modular types, where the
2886 -- bounds are 0 .. modulus - 1). References a node in the tree that
2887 -- contains the bounds for the range. Note that this information
2888 -- could be obtained by rummaging around the tree, but it is more
2889 -- convenient to have it immediately at hand in the entity. The
2890 -- contents of Scalar_Range can either be an N_Subtype_Indication
2891 -- node (with a constraint), or a Range node, but not a simple
2892 -- subtype reference (a subtype is converted into a range).
2894 -- Scale_Value (Uint15)
2895 -- Present in decimal fixed-point types and subtypes. Contains the scale
2896 -- for the type (i.e. the value of type'Scale = the number of decimal
2897 -- digits after the decimal point).
2900 -- Present in all entities. Points to the entity for the scope (block,
2901 -- loop, subprogram, package etc.) in which the entity is declared.
2902 -- Since this field is in the base part of the entity node, the access
2903 -- routines for this field are in Sinfo.
2905 -- Scope_Depth (synth)
2906 -- Applies to program units, blocks, concurrent types and entries,
2907 -- and also to record types, i.e. to any entity that can appear on
2908 -- the scope stack. Yields the scope depth value, which for those
2909 -- entities other than records is simply the scope depth value,
2910 -- for record entities, it is the Scope_Depth of the record scope.
2912 -- Scope_Depth_Value (Uint22)
2913 -- Present in program units, blocks, concurrent types and entries.
2914 -- Indicates the number of scopes that statically enclose the
2915 -- declaration of the unit or type. Library units have a depth of zero.
2916 -- Note that record types can act as scopes but do NOT have this field
2917 -- set (see Scope_Depth above)
2919 -- Scope_Depth_Set (synthesized)
2920 -- Applies to a special predicate function that returns a Boolean value
2921 -- indicating whether or not the Scope_Depth field has been set. It
2922 -- is needed, since returns an invalid value in this case!
2924 -- Sec_Stack_Needed_For_Return (Flag167)
2925 -- Present in scope entities (blocks, functions, procedures, tasks,
2926 -- entries). Set to True when secondary stack is used to hold
2927 -- the returned value of a function and thus should not be
2928 -- released on scope exit.
2930 -- Shadow_Entities (List14)
2931 -- Present in package and generic package entities. Points to a list
2932 -- of entities that correspond to private types. For each private type
2933 -- a shadow entity is created that holds a copy of the private view.
2934 -- In regions of the program where the full views of these private
2935 -- entities are visible, the full view is copied into the entity that
2936 -- is normally used to hold the private view, but the shadow entity
2937 -- copy is unchanged. The shadow entities are then used to restore the
2938 -- original private views at the end of the region. This list is a
2939 -- standard format list (i.e. First (Shadow_Entities) is the first
2940 -- entry and subsequent entries are obtained using Next.
2942 -- Shared_Var_Assign_Proc (Node22)
2943 -- Present in variables. Set non-Empty only if Is_Shared_Passive is
2944 -- set, in which case this is the entity for the shared memory assign
2945 -- routine. See Exp_Smem for full details.
2947 -- Shared_Var_Read_Proc (Node15)
2948 -- Present in variables. Set non-Empty only if Is_Shared_Passive is
2949 -- set, in which case this is the entity for the shared memory read
2950 -- routine. See Exp_Smem for full details.
2952 -- Size_Check_Code (Node19)
2953 -- Present in constants and variables. Normally Empty. Set if code is
2954 -- generated to check the size of the object. This field is used to
2955 -- suppress this code if a subsequent address clause is encountered.
2957 -- Size_Clause (synthesized)
2958 -- Applies to all entities. If a size clause is present in the rep
2959 -- item chain for an entity then the attribute definition clause node
2960 -- for the size clause is returned. Otherwise Size_Clause returns Empty
2961 -- if no item is present. Usually this is only meaningful if the flag
2962 -- Has_Size_Clause is set. This is because when the representation item
2963 -- chain is copied for a derived type, it can inherit a size clause that
2964 -- is not applicable to the entity.
2966 -- Size_Depends_On_Discriminant (Flag177)
2967 -- Present in all entities for types and subtypes. Indicates that the
2968 -- size of the type depends on the value of one or more discriminants.
2969 -- Currently, this flag is only set in front end layout mode for arrays
2970 -- which have one or more bounds depending on a discriminant value.
2972 -- Size_Known_At_Compile_Time (Flag92)
2973 -- Present in all entities for types and subtypes. Indicates that the
2974 -- size of objects of the type is known at compile time. This flag is
2975 -- used to optimize some generated code sequences, and also to enable
2976 -- some error checks (e.g. disallowing component clauses on variable
2977 -- length objects. It is set conservatively (i.e. if it is True, the
2978 -- size is certainly known at compile time, if it is False, then the
2979 -- size may or may not be known at compile time, but the code will
2980 -- assume that it is not known).
2982 -- Small_Value (Ureal21)
2983 -- Present in fixed point types. Points to the universal real for the
2984 -- Small of the type, either as given in a representation clause, or
2985 -- as computed (as a power of two) by the compiler.
2987 -- Spec_Entity (Node19)
2988 -- Present in package body entities. Points to corresponding package
2989 -- spec entity. Also present in subprogram body parameters in the
2990 -- case where there is a separate spec, where this field references
2991 -- the corresponding parameter entities in the spec.
2993 -- Storage_Size_Variable (Node15) [implementation base type only]
2994 -- Present in access types and task type entities. This flag is set
2995 -- if a valid and effective pragma Storage_Size applies to the base
2996 -- type. Points to the entity for a variable that is created to
2997 -- hold the value given in a Storage_Size pragma for an access
2998 -- collection or a task type. Note that in the access type case,
2999 -- this field is present only in the root type (since derived types
3000 -- share the same storage pool).
3002 -- Stored_Constraint (Elist23)
3003 -- Present in entities that can have discriminants (concurrent types
3004 -- subtypes, record types and subtypes, private types and subtypes,
3005 -- limited private types and subtypes and incomplete types). Points
3006 -- to an element list containing the expressions for each of the
3007 -- stored discriminants for the record (sub)type.
3009 -- Strict_Alignment (Flag145) [implementation base type only]
3010 -- Present in all type entities. Indicates that some containing part
3011 -- is either aliased or tagged. This prohibits packing the object
3012 -- tighter than its natural size and alignment.
3014 -- String_Literal_Length (Uint16)
3015 -- Present in string literal subtypes (which are created to correspond
3016 -- to string literals in the program). Contains the length of the string
3019 -- String_Literal_Low_Bound (Node15)
3020 -- Present in string literal subtypes (which are created to correspond
3021 -- to string literals in the program). Contains an expression whose
3022 -- value represents the low bound of the literal. This is a copy of
3023 -- the low bound of the applicable index constraint if there is one,
3024 -- or a copy of the low bound of the index base type if not.
3026 -- Suppress_Elaboration_Warnings (Flag148)
3027 -- Present in all entities, relevant only for subprogram entities. If
3028 -- this flag is set then Sem_Elab will not generate elaboration warnings
3029 -- for the subprogram. Suppression of such warnings is automatic for
3030 -- subprograms for which elaboration checks are suppressed (without the
3031 -- need to set this flag), but the flag is also set for various internal
3032 -- entities (such as init procs) which are known not to generate any
3033 -- possible access before elaboration. (we need a clear description of
3034 -- how this flag differs in effect from Elaboration_Checks_Suppressed???)
3036 -- Suppress_Init_Proc (Flag105) [base type only]
3037 -- Present in all type entities. Set to suppress the generation of
3038 -- initialization procedures where they are known to be not needed.
3039 -- For example, the enumeration image table entity uses this flag.
3041 -- Suppress_Style_Checks (Flag165)
3042 -- Present in all entities. Suppresses any style checks specifically
3043 -- associated with the given entity if set.
3045 -- Tag_Component (synthesized)
3046 -- Applies to tagged record types, returns the entity for the _Tag
3047 -- field in this record, which must be present.
3049 -- Treat_As_Volatile (Flag41)
3050 -- Present in all type entities, and also in constants, components and
3051 -- variables. Set if this entity is to be treated as volatile for code
3052 -- generation purposes. Always set if Is_Volatile is set, but can also
3053 -- be set as a result of situations (such as address overlays) where
3054 -- the front end wishes to force volatile handling to inhibit aliasing
3055 -- optimization which might be legally ok, but is undesirable. Note
3056 -- that the back end always tests this flag rather than Is_Volatile.
3057 -- The front end tests Is_Volatile if it is concerned with legality
3058 -- checks associated with declared volatile variables, but if the test
3059 -- is for the purposes of suppressing optimizations, then the front
3060 -- end should test Treat_As_Volatile rather than Is_Volatile.
3062 -- Type_High_Bound (synthesized)
3063 -- Applies to scalar types. Returns the tree node (Node_Id) that
3064 -- contains the high bound of a scalar type. The returned value is a
3065 -- literal for a base type, but may be an expression in the case of a
3066 -- scalar type with dynamic bounds. Note that in the case of a fixed
3067 -- point type, the high bound is in units of small, and is an integer.
3069 -- Type_Low_Bound (synthesized)
3070 -- Applies to scalar types. Returns the tree node (Node_Id) that
3071 -- contains the low bound of a scalar type. The returned value is a
3072 -- literal for a base type, but may be an expression in the case of a
3073 -- scalar type with dynamic bounds. Note that in the case of a fixed
3074 -- point type, the low bound is in units of small, and is an integer.
3076 -- Underlying_Full_View (Node19)
3077 -- Present in private subtypes that are the completion of other private
3078 -- types, or in private types that are derived from private subtypes.
3079 -- If the full view of a private type T is derived from another
3080 -- private type with discriminants Td, the full view of T is also
3081 -- private, and there is no way to attach to it a further full view that
3082 -- would convey the structure of T to the back end. The Underlying_Full_
3083 -- View is an attribute of the full view that is a subtype of Td with
3084 -- the same constraint as the declaration for T. The declaration for this
3085 -- subtype is built at the point of the declaration of T, either as a
3086 -- completion, or as a subtype declaration where the base type is private
3087 -- and has a private completion. If Td is already constrained, then its
3088 -- full view can serve directly as the full view of T.
3090 -- Underlying_Type (synthesized)
3091 -- Applies to all entities. This is the identity function except in
3092 -- the case where it is applied to an incomplete or private type,
3093 -- in which case it is the underlying type of the type declared by
3094 -- the completion, or Empty if the completion has not yet been
3095 -- encountered and analyzed.
3097 -- Note: the reason this attribute applies to all entities, and not
3098 -- just types, is to legitimize code where Underlying_Type is applied
3099 -- to an entity which may or may not be a type, with the intent that
3100 -- if it is a type, its underlying type is taken.
3102 -- Unset_Reference (Node16)
3103 -- Present in variables and out parameters. This is normally Empty.
3104 -- It is set to point to an identifier that represents a reference
3105 -- to the entity before any value has been set. Only the first such
3106 -- reference is identified. This field is used to generate a warning
3107 -- message if necessary (see Sem_Warn.Check_Unset_Reference).
3109 -- Uses_Sec_Stack (Flag95)
3110 -- Present in scope entities (blocks,functions, procedures, tasks,
3111 -- entries). Set to True when secondary stack is used in this scope and
3112 -- must be released on exit unless Sec_Stack_Needed_For_Return is set.
3114 -- Vax_Float (Flag151) [base type only]
3115 -- Present in all type entities. Set only on the base type of float
3116 -- types with Vax format. The particular format is determined by the
3117 -- Digits_Value value which is 6,9,15 for F_Float, D_Float, G_Float.
3119 -- Warnings_Off (Flag96)
3120 -- Present in all entities. Set if a pragma Warnings (Off, entity-name)
3121 -- is used to suppress warnings for a given entity. It is also used by
3122 -- the compiler in some situations to kill spurious warnings.
3128 -- The following three entity kinds are introduced by the corresponding
3129 -- type definitions:
3132 -- E_General_Access_Type,
3133 -- E_Anonymous_Access_Subprogram_Type,
3134 -- E_Anonymous_Access_Protected_Subprogram_Type
3135 -- E_Anonymous_Access_Type.
3137 -- In addition, we define the kind E_Allocator_Type to label
3138 -- allocators. This is because special resolution rules apply to this
3139 -- construct. Eventually the constructs are labeled with the access
3140 -- type imposed by the context. Gigi should never see the type
3143 -- Similarly, the type E_Access_Attribute_Type is used as the initial
3144 -- kind associated with an access attribute. After resolution a specific
3145 -- access type will be established as determined by the context.
3147 -- Finally, the type Any_Access is used to label -null- during type
3148 -- resolution. Any_Access is also replaced by the context type after
3151 --------------------------------
3152 -- Classification of Entities --
3153 --------------------------------
3155 -- The classification of program entities which follows is a refinement of
3156 -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
3157 -- different type classes. Ada 95 entities include class wide types,
3158 -- protected types, subprogram types, generalized access types, generic
3159 -- formal derived types and generic formal packages.
3161 -- The order chosen for these kinds allows us to classify related entities
3162 -- so that they are contiguous. As a result, they do not appear in the
3163 -- exact same order as their order of first appearance in the LRM (For
3164 -- example, private types are listed before packages). The contiguity
3165 -- allows us to define useful subtypes (see below) such as type entities,
3166 -- overloaded entities, etc.
3168 -- Each entity (explicitly or implicitly declared) has a kind, which is
3169 -- a value of the following type:
3171 type Entity_Kind is (
3174 -- The initial Ekind value for a newly created entity. Also used as
3175 -- the Ekind for Standard_Void_Type, a type entity in Standard used
3176 -- as a dummy type for the return type of a procedure (the reason we
3177 -- create this type is to share the circuits for performing overload
3178 -- resolution on calls).
3185 -- Variables created by an object declaration with no constant keyword
3188 -- Components of a record declaration, private declarations of
3189 -- protected objects.

3259 E_Signed_Integer_Subtype,
3260 -- Signed integer subtype, created by either an integer subtype or

3266 -- integer subtype created by a modular integer type declaration.
3268 E_Modular_Integer_Subtype,

3277 E_Ordinary_Fixed_Point_Subtype,

3320 -- 'Unrestricted_Access and Unchecked_Access)
3323 -- A special internal type used to label allocators and attribute
3324 -- references using 'Access. This is needed because special resolution
3325 -- rules apply to these constructs. On the resolution pass, this type

3327 -- see types with this Ekind.
3329 E_General_Access_Type,

4750 -- Since E_Void is the initial Ekind value of an entity when it is first
4751 -- created, one might expect that no attributes would be defined on such
4752 -- an entity until its Ekind field is set. However, in practice, there
4753 -- are many instances in which fields of an E_Void entity are set in the
4754 -- code prior to setting the Ekind field. This is not well documented or
4755 -- well controlled, and needs cleaning up later. Meanwhile, the access
4756 -- procedures in the body of Einfo permit many, but not all, attributes
4757 -- to be applied to an E_Void entity, precisely so that this kind of
4758 -- pre-setting of attributes works. This is really a hole in the dynamic
4759 -- type checking, since there is no assurance that the eventual Ekind
4760 -- value will be appropriate for the attributes set, and the consequence
4761 -- is that the dynamic type checking in the Einfo body is unnecessarily
4762 -- weak. To be looked at systematically some time ???

4765 -- Component_Alignment Control --
4766 ---------------------------------
4768 -- There are four types of alignment possible for array and record
4769 -- types, and a field in the type entities contains a value of the
4770 -- following type indicating which alignment choice applies. For full
4771 -- details of the meaning of these aligment types, see description
4772 -- of the Component_Alignment pragma
4774 type Component_Alignment_Kind is (
4775 Calign_Default, -- default alignment
4776 Calign_Component_Size, -- natural alignment for component size
4777 Calign_Component_Size_4, -- natural for size <= 4, 4 for size >= 4
4778 Calign_Storage_Unit); -- all components byte aligned
4784 -- In addition to attributes that are stored as plain data, other
4785 -- attributes are procedural, and require some small amount of
4786 -- computation. Of course, from the point of view of a user of this
4787 -- package, the distinction is not visible (even the field information
4788 -- provided below should be disregarded, as it is subject to change
4789 -- without notice!). A number of attributes appear as lists: lists of

4794 -- function Next_Thing (T : Thing) return Thing;
4796 -- The end of iteration is always signaled by a value of Empty, so that

4810 -- Handling of Check Suppression --
4811 -----------------------------------
4813 -- There are three ways that checks can be suppressed:
4815 -- 1. At the command line level
4816 -- 2. At the scope level.
4817 -- 3. At the entity level.
4819 -- See spec of Sem in sem.ads for details of the data structures used
4820 -- to keep track of these various methods for suppressing checks.
4822 -------------------------------
4823 -- Handling of Discriminants --
4824 -------------------------------
4826 -- During semantic processing, discriminants are separate entities which
4827 -- reflect the semantic properties and allowed usage of discriminants in
4830 -- In the case of discriminants used as bounds, the references are handled
4831 -- directly, since special processing is needed in any case. However, there
4832 -- are two circumstances in which discriminants are referenced in a quite
4833 -- general manner, like any other variables:
4835 -- In initialization expressions for records. Note that the expressions
4836 -- used in Priority, Storage_Size, and Task_Info pragmas are effectively
4837 -- in this category, since these pragmas are converted to initialized
4838 -- record fields in the Corresponding_Record_Type.
4840 -- In task and protected bodies, where the discriminant values may be
4841 -- referenced freely within these bodies. Discriminants can also appear
4842 -- in bounds of entry families and in defaults of operations.
4844 -- In both these cases, the discriminants must be treated essentially as
4845 -- objects. The following approach is used to simplify and minimize the
4846 -- special processing that is required.
4848 -- When a record type with discriminants is processed, the semantic
4849 -- processing creates the entities for the discriminants. It also creates
4850 -- an additional set of entities, called discriminals, one for each of
4851 -- the discriminants, and the Discriminal field of the discriminant entity
4852 -- points to this additional entity, which is initially created as an
4853 -- uninitialized (E_Void) entity.
4855 -- During expansion of expressions, any discriminant reference is replaced
4856 -- by a reference to the corresponding discriminal. When the initialization
4857 -- procedure for the record is created (there will always be one, since
4858 -- discriminants are present, see Exp_Ch3 for further details), the
4859 -- discriminals are used as the entities for the formal parameters of
4860 -- this initialization procedure. The references to these discriminants
4861 -- have already been replaced by references to these discriminals, which
4862 -- are now the formal parameters corresponding to the required objects.
4864 -- In the case of a task or protected body, the semantics similarly
4865 -- creates a set of discriminals for the discriminants of the task or
4866 -- protected type. When the procedure is created for the task body,
4867 -- the parameter passed in is a reference to the task value type, which
4868 -- contains the required discriminant values. The expander creates a
4869 -- set of declarations of the form:
4871 -- discriminal : constant dtype renames _Task.discriminant;
4873 -- where discriminal is the discriminal entity referenced by the task
4874 -- discriminant, and _Task is the task value passed in as the parameter.
4875 -- Again, any references to discriminants in the task body have been
4876 -- replaced by the discriminal reference, which is now an object that
4877 -- contains the required value.
4879 -- This approach for tasks means that two sets of discriminals are needed
4880 -- for a task type, one for the initialization procedure, and one for the
4881 -- task body. This works out nicely, since the semantics allocates one set
4882 -- for the task itself, and one set for the corresponding record.
4884 -- The one bit of trickiness arises in making sure that the right set of
4885 -- discriminals is used at the right time. First the task definition is
4886 -- processed. Any references to discriminants here are replaced by the
4887 -- the corresponding *task* discriminals (the record type doesn't even
4888 -- exist yet, since it is constructed as part of the expansion of the
4889 -- task declaration, which happens after the semantic processing of the
4890 -- task definition). The discriminants to be used for the corresponding
4891 -- record are created at the same time as the other discriminals, and
4892 -- held in the CR_Discriminant field of the discriminant. A use of the
4893 -- discriminant in a bound for an entry family is replaced with the CR_
4894 -- discriminant because it controls the bound of the entry queue array
4895 -- which is a component of the corresponding record.
4897 -- Just before the record initialization routine is constructed, the
4898 -- expander exchanges the task and record discriminals. This has two
4899 -- effects. First the generation of the record initialization routine
4900 -- uses the discriminals that are now on the record, which is the set
4901 -- that used to be on the task, which is what we want.
4903 -- Second, a new set of (so far unused) discriminals is now on the task
4904 -- discriminants, and it is this set that will be used for expanding the
4905 -- task body, and also for the discriminal declarations at the start of
4908 ---------------------------------------
4909 -- Private data in protected objects --
4910 ---------------------------------------
4912 -- Private object declarations in protected types pose problems
4913 -- similar to those of discriminants. They are expanded to components
4914 -- of a record which is passed as the parameter "_object" to expanded
4915 -- forms of all protected operations. As with discriminants, timing
4916 -- of this expansion is a problem. The sequence of statements for a
4917 -- protected operation is expanded before the operation itself, so the
4918 -- formal parameter for the record object containing the private data
4919 -- does not exist when the references to that data are expanded.
4921 -- For this reason, private data is handled in the same way as
4922 -- discriminants, expanding references to private data in protected
4923 -- operations (which appear as components) to placeholders which will
4924 -- eventually become renamings of the private selected components
4925 -- of the "_object" formal parameter. These placeholders are called
4926 -- "privals", by analogy to the "discriminals" used to implement
4927 -- discriminants. They are attached to the component declaration nodes
4928 -- representing the private object declarations of the protected type.
4930 -- As with discriminals, each protected subprogram needs a unique set
4931 -- of privals, since they must refer to renamings of components of a
4932 -- formal parameter of that operation. Entry bodies need another set,
4933 -- which they all share and which is associated with renamings in the
4934 -- Service_Entries procedure for the protected type (this is not yet
4935 -- implemented???). This means that we must associate a new set of
4936 -- privals (and discriminals) with the private declarations after
4937 -- the body of a protected subprogram is processed.
4939 -- The last complication is the presence of discriminants and discriminated
4940 -- components. In the corresponding record, the components are constrained
4941 -- by the discriminants of the record, but within each protected operation
4942 -- they are constrained by the discriminants of the actual. The actual
4943 -- subtypes of those components are constructed as for other unconstrained
4944 -- formals, but the privals are created before the formal object is added
4945 -- to the parameter list of the protected operation, so they carry the
4946 -- nominal subtype of the original component. After the protected operation
4947 -- is actually created (in the expansion of the protected body) we must
4948 -- patch the types of each prival occurrence with the proper actual subtype
4949 -- which is by now set. The Privals_Chain is used for this patching.
4955 -- The following type synonyms are used to tidy up the function and
4956 -- procedure declarations that follow, and also to make it possible
4957 -- to meet the requirement for the XEINFO utility that all function
4958 -- specs must fit on a single source line.
