41 -- This package defines the annotations to the abstract syntax tree that
42 -- are needed to support semantic processing of an Ada compilation.
44 -- Note that after editing this spec and the corresponding body it is
45 -- required to run ceinfo to check the consistentcy of spec and body.
46 -- See ceinfo.adb for more information about the checks made.
48 -- These annotations are for the most part attributes of declared entities,
49 -- and they correspond to conventional symbol table information. Other
50 -- attributes include sets of meanings for overloaded names, possible
51 -- types for overloaded expressions, flags to indicate deferred constants,
52 -- incomplete types, etc. These attributes are stored in available fields
53 -- in tree nodes (i.e. fields not used by the parser, as defined by the
54 -- Sinfo package specification), and accessed by means of a set of
55 -- subprograms which define an abstract interface.
57 -- There are two kinds of semantic information
59 -- First, the tree nodes with the following Nkind values:
61 -- N_Defining_Identifier
62 -- N_Defining_Character_Literal
63 -- N_Defining_Operator_Symbol
65 -- are called Entities, and constitute the information that would often
66 -- be stored separately in a symbol table. These nodes are all extended
67 -- to provide extra space, and contain fields which depend on the entity
68 -- kind, as defined by the contents of the Ekind field. The use of the
69 -- Ekind field, and the associated fields in the entity, are defined
70 -- in this package, as are the access functions to these fields.
72 -- Second, in some cases semantic information is stored directly in other
73 -- kinds of nodes, e.g. the Etype field, used to indicate the type of an
74 -- expression. The access functions to these fields are defined in the
75 -- Sinfo package, but their full documentation is to be found in
76 -- the Einfo package specification.
78 -- Declaration processing places information in the nodes of their defining
79 -- identifiers. Name resolution places in all other occurrences of an
80 -- identifier a pointer to the corresponding defining occurrence.
82 --------------------------------
83 -- The XEINFO Utility Program --
84 --------------------------------
86 -- XEINFO is a utility program which automatically produces a C header file,
87 -- a-xeinfo.h from the spec and body of package Einfo. It reads the input
88 -- files einfo.ads and einfo.adb and produces the output file a-xeinfo.h.
90 -- In order for this utility program to operate correctly, the form of the
91 -- einfo.ads and einfo.adb files must meet certain requirements and be laid
92 -- out in a specific manner.
94 -- The general form of einfo.ads is as follows:
96 -- type declaration for type Entity_Kind
97 -- subtype declarations declaring subranges of Entity_Kind
98 -- subtype declarations declaring synonyms for some standard types
99 -- function specs for attributes
101 -- pragma Inline declarations
103 -- This order must be observed. There are no restrictions on the procedures,
104 -- since the C header file only includes functions (Gigi is not allowed to
105 -- modify the generated tree). However, functions are required to have headers
106 -- that fit on a single line.
108 -- XEINFO reads and processes the function specs and the pragma Inlines. For
109 -- functions that are declared as inlined, XEINFO reads the corresponding body
110 -- from xeinfo.adb, and processes it into C code. This results in some strict
111 -- restrictions on which functions can be inlined:
113 -- The function spec must be on a single line
115 -- There can only be a single statement, contained on a single line,
116 -- not counting any pragma Assert statements.
118 -- This single statement must either be a function call with simple,
119 -- single token arguments, or it must be a membership test of the form
120 -- a in b, where a and b are single tokens.
122 -- For functions that are not inlined, there is no restriction on the body,
123 -- and XEINFO generates a direct reference in the C header file which allows
124 -- the C code in Gigi to directly call the corresponding Ada body.
126 ----------------------------------
127 -- Handling of Type'Size Values --
128 ----------------------------------
130 -- The Ada 95 RM contains some rather peculiar (to us!) rules on the value
131 -- of type'Size (see RM 13.3(55)). We have found that attempting to use
132 -- these RM Size values generally, and in particular for determining the
133 -- default size of objects, creates chaos, and major incompatibilies in
136 -- We proceed as follows, for discrete and fixed-point subtypes, we have
137 -- two separate sizes for each subtype:
139 -- The Object_Size, which is used for determining the default size of
140 -- objects and components. This size value can be referred to using the
141 -- Object_Size attribute. The phrase "is used" here means that it is
142 -- the basis of the determination of the size. The backend is free to
143 -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
144 -- character might be stored in 32 bits on a machine with no efficient
145 -- byte access instructions such as the Alpha.
147 -- The default rules for the value of Object_Size for fixed-point and
148 -- discrete types are as follows:
150 -- The Object_Size for base subtypes reflect the natural hardware
151 -- size in bits (see Ttypes and Cstand for integer types). For
152 -- enumeration and fixed-point base subtypes have 8. 16. 32 or 64
153 -- bits for this size, depending on the range of values to be stored.
155 -- The Object_Size of a subtype is the same as the Object_Size of
156 -- the subtype from which it is obtained.
158 -- The Object_Size of a derived base type is copied from the parent
159 -- base type, and the Object_Size of a derived first subtype is copied
160 -- from the parent first subtype.
162 -- The Value_Size which is the number of bits required to store a value
163 -- of the type. This size can be referred to using the Value_Size
164 -- attribute. This value is used to determine how tightly to pack
165 -- records or arrays with components of this type, and also affects
166 -- the semantics of unchecked conversion (unchecked conversions where
167 -- the Value_Size values differ generate a warning, and are potentially
168 -- target dependent).
170 -- The default rule for the value of Value_Size are as follows:
172 -- The Value_Size for a base subtype is the minimum number of bits
173 -- required to store all values of the type (including the sign bit
174 -- only if negative values are possible).
176 -- If a subtype statically matches the first subtype, then it has
177 -- by default the same Value_Size as the first subtype. This is a
178 -- consequence of RM 13.1(14) ("if two subtypes statically match,
179 -- then their subtype-specific aspects are the same".)
181 -- All other subtypes have a Value_Size corresponding to the minimum
182 -- number of bits required to store all values of the subtype. For
183 -- dynamic bounds, it is assumed that the value can range down or up
184 -- to the corresponding bound of the ancestor
186 -- The RM defined attribute Size corresponds to the Value_Size attribute
188 -- The Size attribute may be defined for a first-named subtype. This sets
189 -- the Value_Size of the first-named subtype to the given value, and the
190 -- Object_Size of this first-named subtype to the given value padded up
191 -- to an appropriate boundary. It is a consequence of the default rules
192 -- above that this Object_Size will apply to all further subtypes. On the
193 -- otyher hand, Value_Size is affected only for the first subtype, any
194 -- dynamic subtypes obtained from it directly, and any statically matching
195 -- subtypes. The Value_Size of any other static subtypes is not affected.
197 -- Value_Size and Object_Size may be explicitly set for any subtype using
198 -- an attribute definition clause. Note that the use of these attributes
199 -- can cause the RM 13.1(14) rule to be violated. If two access types
200 -- reference aliased objects whose subtypes have differing Object_Size
201 -- values as a result of explicit attribute definition clauses, then it
202 -- is erroneous to convert from one access subtype to the other.
204 -- At the implementation level, Esize stores the Object_Size and the
205 -- RM_Size field stores the Value_Size (and hence the value of the
206 -- Size attribute, which, as noted above, is equivalent to Value_Size).
208 -- To get a feel for the difference, consider the following examples (note
209 -- that in each case the base is short_short_integer with a size of 8):
211 -- Object_Size Value_Size
213 -- type x1 is range 0..5; 8 3
215 -- type x2 is range 0..5;
216 -- for x2'size use 12; 12 12
218 -- subtype x3 is x2 range 0 .. 3; 12 2
220 -- subtype x4 is x2'base range 0 .. 10; 8 4
222 -- subtype x5 is x2 range 0 .. dynamic; 12 (7)
224 -- subtype x6 is x2'base range 0 .. dynamic; 8 (7)
226 -- Note: the entries marked (7) are not actually specified by the Ada 95 RM,
227 -- but it seems in the spirit of the RM rules to allocate the minimum number
228 -- of bits known to be large enough to hold the given range of values.
230 -- So far, so good, but GNAT has to obey the RM rules, so the question is
231 -- under what conditions must the RM Size be used. The following is a list
232 -- of the occasions on which the RM Size must be used:
234 -- Component size for packed arrays or records
235 -- Value of the attribute Size for a type
236 -- Warning about sizes not matching for unchecked conversion
238 -- The RM_Size field keeps track of the RM Size as needed in these
241 -- For types other than discrete and fixed-point types, the Object_Size
242 -- and Value_Size are the same (and equivalent to the RM attribute Size).
243 -- Only Size may be specified for such types.
245 -----------------------
246 -- Entity Attributes --
247 -----------------------
249 -- This section contains a complete list of the attributes that are defined
250 -- on entities. Some attributes apply to all entities, others only to certain
251 -- kinds of entities. In the latter case the attribute should only be set or
252 -- accessed if the Ekind field indicates an appropriate entity.
254 -- There are two kinds of attributes that apply to entities, stored and
255 -- synthesized. Stored attributes correspond to a field or flag in the entity
256 -- itself. Such attributes are identified in the table below by giving the
257 -- field or flag in the attribute that is used to hold the attribute value.
258 -- Synthesized attributes are not stored directly, but are rather computed as
259 -- needed from other attributes, or from information in the tree. These are
260 -- marked "synthesized" in the table below. The stored attributes have both
261 -- access functions and set procedures to set the corresponding values, while
262 -- synthesized attributes have only access functions.
264 -- Note: in the case of Node, Uint, or Elist fields, there are cases where
265 -- the same physical field is used for different purposes in different
266 -- entities, so these access functions should only be referenced for the
267 -- class of entities in which they are defined as being present. Flags are
268 -- not overlapped in this way, but nevertheless as a matter of style and
269 -- abstraction (which may or may not be checked by assertions in the body),
270 -- this restriction should be observed for flag fields as well.
272 -- Note: certain of the attributes on types apply only to base types, and
273 -- are so noted by the notation [base type only]. These are cases where the
274 -- attribute of any subtype is the same as the attribute of the base type.
275 -- The attribute can be referenced on a subtype (and automatically retrieves
276 -- the value from the base type). However, it is an error to try to set the
277 -- attribute on other than the base type, and if assertions are enabled,
278 -- an attempt to set the attribute on a subtype will raise an assert error.
280 -- Other attributes are noted as applying the implementation base type only.
281 -- These are representation attributes which must always apply to a full
282 -- non-private type, and where the attributes are always on the full type.
283 -- The attribute can be referenced on a subtype (and automatically retries
284 -- the value from the implementation base type). However, it is an error
285 -- to try to set the attribute on other than the implementation base type,
286 -- and if assertions are enabled, an attempt to set the attribute on a
287 -- subtype will raise an assert error.
289 -- Abstract_Interfaces (Elist24)
290 -- Present in record types and subtypes. List of abstract interfaces
291 -- implemented by a tagged type that are not already implemented by the
292 -- ancestors (Ada 2005: AI-251).
294 -- Abstract_Interface_Alias (Node25)
295 -- Present in subprograms that cover a primitive operation of an abstract
296 -- interface type. Points to its associated interface subprogram. It is
297 -- used to register the subprogram in secondary dispatch table of the
298 -- interface (Ada 2005: AI-251).
300 -- Accept_Address (Elist21)
301 -- Present in entries. If an accept has a statement sequence, then an
302 -- address variable is created, which is used to hold the address of the
303 -- parameters, as passed by the runtime. Accept_Address holds an element
304 -- list which represents a stack of entities for these address variables.
305 -- The current entry is the top of the stack, which is the last element
306 -- on the list. A stack is required to handle the case of nested select
307 -- statements referencing the same entry.
309 -- Actual_Subtype (Node17)
310 -- Present in variables, constants, and formal parameters. This is the
311 -- subtype imposed by the value of the object, as opposed to its nominal
312 -- subtype, which is imposed by the declaration. The actual subtype
313 -- differs from the nominal one when the latter is indefinite (as in the
314 -- case of an unconstrained formal parameter, or a variable declared
315 -- with an unconstrained type and an initial value). The nominal subtype
316 -- is the Etype entry for the entity. The Actual_Subtype field is set
317 -- only if the actual subtype differs from the nominal subtype. If the
318 -- actual and nominal subtypes are the same, then the Actual_Subtype
319 -- field is Empty, and Etype indicates both types.
321 -- For objects, the Actual_Subtype is set only if this is a discriminated
322 -- type. For arrays, the bounds of the expression are obtained and the
323 -- Etype of the object is directly the constrained subtype. This is
324 -- rather irregular, and the semantic checks that depend on the nominal
325 -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
327 -- Access_Disp_Table (Elist16) [implementation base type only]
328 -- Present in record type entities. For a tagged type, points to the
329 -- dispatch tables associated with the tagged type. For a non-tagged
330 -- record, contains Empty.
332 -- Address_Clause (synthesized)
333 -- Applies to entries, objects and subprograms. Set if an address clause
334 -- is present which references the object or subprogram and points to
335 -- the N_Attribute_Definition_Clause node. Empty if no Address clause.
336 -- The expression in the address clause is always a constant that is
337 -- defined before the entity to which the address clause applies.
338 -- Note: Gigi references this field in E_Task_Type entities???
340 -- Address_Taken (Flag104)
341 -- Present in all entities. Set if the Address or Unrestricted_Access
342 -- attribute is applied directly to the entity, i.e. the entity is the
343 -- entity of the prefix of the attribute reference. Used by Gigi to
344 -- make sure that the address can be meaningfully taken.
347 -- Present in overloaded entities (literals, subprograms, entries).
348 -- Points to parent subprogram of a derived subprogram. Also used for
349 -- a subprogram renaming, where it points to the renamed subprogram.
350 -- Always empty for entries.
352 -- Alignment (Uint14)
353 -- Present in entities for types and also in constants, variables,
354 -- loop parameters, and formal parameters. This indicates the desired
355 -- alignment for a type, or the actual alignment for an object. A value
356 -- of zero (Uint_0) indicates that the alignment has not been set yet.
357 -- The alignment can be set by an explicit alignment clause, or set by
358 -- the front-end in package Layout, or set by the back-end as part of
359 -- the back end back-annotation process. The alignment field is also
360 -- present in E_Exception entities, but there it is used only by the
361 -- back-end for back annotation.
363 -- Alignment_Clause (synthesized)
364 -- Appllies to all entities for types and objects. If an alignment
365 -- attribute definition clause is present for the entity, then this
366 -- function returns the N_Attribute_Definition clause that specifies the
367 -- alignment. If no alignment clause applies to the type, then the call
368 -- to this function returns Empty. Note that the call can return a
369 -- non-Empty value even if Has_Alignment_Clause is not set (happens with
370 -- subtype and derived type declarations). Note also that a record
371 -- definition clause with an (obsolescent) mod clause is converted
372 -- into an attribute definition clause for this purpose.
374 -- Ancestor_Subtype (synthesized)
375 -- Applies to all type and subtype entities. If the argument is a
376 -- subtype then it returns the subtype or type from which the subtype
377 -- was obtained, otherwise it returns Empty.
379 -- Associated_Formal_Package (Node12)
380 -- Present in packages that are the actuals of formal_packages. Points
381 -- to the entity in the declaration for the formal package.
383 -- Associated_Node_For_Itype (Node8)
384 -- Present in all type and subtype entities. Set non-Empty only for
385 -- Itypes. Set to point to the associated node for the Itype, i.e.
386 -- the node whose elaboration generated the Itype. This is used for
387 -- copying trees, to determine whether or not to copy an Itype.
389 -- Associated_Storage_Pool (Node22) [root type only]
390 -- Present in simple and general access type entities. References the
391 -- storage pool to be used for the corresponding collection. A value of
392 -- Empty means that the default pool is to be used. This is present
393 -- only in the root type, since derived types must have the same pool
394 -- as the parent type.
396 -- Associated_Final_Chain (Node23)
397 -- Present in simple and general access type entities. References the
398 -- List_Controller object that holds the finalization chain on which
399 -- are attached dynamically allocated objects referenced by the access
400 -- type. Empty when the access type cannot reference a controlled object.
402 -- Barrier_Function (Node12)
403 -- Present in protected entries and entry families. This is the
404 -- subprogram declaration for the body of the function that returns
405 -- the value of the entry barrier.
407 -- Base_Type (synthesized)
408 -- Applies to all type entities. Returns the base type of a type or
409 -- subtype. The base type of a type is the type itself. The base type
410 -- of a subtype is the type that it constrains (which is always a type
411 -- entity, not some other subtype). Note that in the case of a subtype
412 -- of a private type, it is possible for the base type attribute to
413 -- return a private type, even if the subtype to which it applies is
414 -- non-private. See also Implementation_Base_Type. Note: it is allowed
415 -- to apply Base_Type to other than a type, in which case it simply
416 -- returns the entity unchanged.
418 -- Block_Node (Node11)
419 -- Present in block entities. Points to the identifier in the
420 -- Block_Statement itself. Used when retrieving the block construct
421 -- for finalization purposes, The block entity has an implicit label
422 -- declaration in the enclosing declarative part, and has otherwise
423 -- no direct connection in the tree with the block statement. The
424 -- link is to the identifier (which is an occurence of the entity)
425 -- and not to the block_statement itself, because the statement may
426 -- be rewritten, e.g. in the process of removing dead code.
428 -- Body_Entity (Node19)
429 -- Present in package and generic package entities, points to the
430 -- corresponding package body entity if one is present.
432 -- Body_Needed_For_SAL (Flag40)
433 -- Present in package and subprogram entities that are compilation
434 -- units. Indicates that the source for the body must be included
435 -- when the unit is part of a standalone library.
437 -- C_Pass_By_Copy (Flag125) [implementation base type only]
438 -- Present in record types. Set if a pragma Convention for the record
439 -- type specifies convention C_Pass_By_Copy. This convention name is
440 -- treated as identical in all respects to convention C, except that
441 -- if it is specified for a record type, then the C_Pass_By_Copy flag
442 -- is set, and if a foreign convention subprogram has a formal of the
443 -- corresponding type, then the parameter passing mechanism will be
444 -- set to By_Copy (unless specifically overridden by an Import or
447 -- Can_Never_Be_Null (Flag38)
448 -- This flag is present in all entities, but can only be set in an
449 -- object which can never have a null value. This is used to avoid
450 -- unncessary resetting of the Is_Known_Non_Null flag for such
451 -- entities. The cases where this is set True are constant access
452 -- values initialized to a non-null value, and access parameters.
455 -- Present in all entities. This field contains an entry into the names
456 -- table that has the character string of the identifier, character
457 -- literal or operator symbol. See Namet for further details. Note that
458 -- throughout the processing of the front end, this name is the simple
459 -- unqualified name. However, just before gigi is called, a call is made
460 -- to Qualify_All_Entity_Names. This causes entity names to be qualified
461 -- using the encoding described in exp_dbug.ads, and from that point on
462 -- (including post gigi steps such as cross-reference generation), the
463 -- entities will contain the encoded qualified names.
465 -- Checks_May_Be_Suppressed (Flag31)
466 -- Present in all entities. Set if a pragma Suppress or Unsuppress
467 -- mentions the entity specifically in the second argument. If this
468 -- flag is set the the Global_Entity_Suppress and Local_Entity_Suppress
469 -- tables must be consulted to determine if the is actually an active
470 -- Suppress or Unsuppress pragma that applies to the entity.
472 -- Class_Wide_Type (Node9)
473 -- Present in all type entities. For a tagged type or subtype, returns
474 -- the corresponding implicitly declared class-wide type. Set to Empty
475 -- for non-tagged types.
477 -- Cloned_Subtype (Node16)
478 -- Present in E_Record_Subtype and E_Class_Wide_Subtype entities.
479 -- Each such entity can either have a Discriminant_Constraint, in
480 -- which case it represents a distinct type from the base type (and
481 -- will have a list of components and discrimants in the list headed by
482 -- First_Entity) or else no such constraint, in which case it will be a
483 -- copy of the base type.
485 -- o Each element of the list in First_Entity is copied from the base
486 -- type; in that case, this field is Empty.
488 -- o The list in First_Entity is shared with the base type; in that
489 -- case, this field points to that entity.
491 -- A record or classwide subtype may also be a copy of some other
492 -- subtype and share the entities in the First_Entity with that subtype.
493 -- In that case, this field points to that subtype.
495 -- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
496 -- this field. Note that this field ONLY appears in subtype entries, not
497 -- in type entries, it is not present, and it is an error to reference
498 -- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
501 -- This flag appears on all nodes, including entities, and indicates
502 -- that the node was created by the scanner or parser from the original
503 -- source. Thus for entities, it indicates that the entity is defined
504 -- in the original source program.
506 -- Component_Alignment (special field) [base type only]
507 -- Present in array and record entities. Contains a value of type
508 -- Component_Alignment_Kind indicating the alignment of components.
509 -- Set to Calign_Default normally, but can be overridden by use of
510 -- the Component_Alignment pragma. Note: this field is currently
511 -- stored in a non-standard way, see body for details.
513 -- Component_Bit_Offset (Uint11)
514 -- Present in record components (E_Component, E_Discriminant) if a
515 -- component clause applies to the component. First bit position of
516 -- given component, computed from the first bit and position values
517 -- given in the component clause. A value of No_Uint means that the
518 -- value is not yet known. The value can be set by the appearence of
519 -- an explicit component clause in a record representation clause,
520 -- or it can be set by the front-end in package Layout, or it can be
521 -- set by the backend. By the time backend processing is completed,
522 -- this field is always set. A negative value is used to represent
523 -- a value which is not known at compile time, and must be computed
524 -- at run-time (this happens if fields of a record have variable
525 -- lengths). See package Layout for details of these values.
527 -- Note: this field is obsolescent, to be eventually replaced entirely
528 -- by Normalized_First_Bit and Normalized_Position, but for the moment,
529 -- gigi is still using (and back annotating) this field, and gigi does
530 -- not know about the new fields. For the front end layout case, the
531 -- Component_Bit_Offset field is only set if it is static, and otherwise
532 -- the new Normalized_First_Bit and Normalized_Position fields are used.
534 -- Component_Clause (Node13)
535 -- Present in record components and discriminants. If a record
536 -- representation clause is present for the corresponding record
537 -- type a that specifies a position for the component, then the
538 -- Component_Clause field of the E_Component entity points to the
539 -- N_Component_Clause node. Set to Empty if no record representation
540 -- clause was present, or if there was no specification for this
543 -- Component_Size (Uint22) [implementation base type only]
544 -- Present in array types. It contains the component size value for
545 -- the array. A value of No_Uint means that the value is not yet set.
546 -- The value can be set by the use of a component size clause, or
547 -- by the front end in package Layout, or by the backend. A negative
548 -- value is used to represent a value which is not known at compile
549 -- time, and must be computed at run-time (this happens if the type
550 -- of the component has a variable length size). See package Layout
551 -- for details of these values.
553 -- Component_Type (Node20) [implementation base type only]
554 -- Present in array types and string types. References component type.
556 -- Constant_Value (synthesized)
557 -- Applies to variables, constants, named integers, and named reals.
558 -- Obtains the initialization expression for the entity. Will return
559 -- Empty for for a deferred constant whose full view is not available
560 -- or in some other cases of internal entities, which cannot be treated
561 -- as constants from the point of view of constant folding. Empty is
562 -- also returned for variables with no initialization expression.
564 -- Corresponding_Concurrent_Type (Node18)
565 -- Present in record types that are constructed by the expander to
566 -- represent task and protected types (Is_Concurrent_Record_Type flag
567 -- set True). Points to the entity for the corresponding task type or
570 -- Corresponding_Discriminant (Node19)
571 -- Present in discriminants of a derived type, when the discriminant is
572 -- used to constrain a discriminant of the parent type. Points to the
573 -- corresponding discriminant in the parent type. Otherwise it is Empty.
575 -- Corresponding_Equality (Node13)
576 -- Present in function entities for implicit inequality operators.
577 -- Denotes the explicit or derived equality operation that creates
578 -- the implicit inequality. Note that this field is not present in
579 -- other function entities, only in implicit inequality routines,
580 -- where Comes_From_Source is always False.
582 -- Corresponding_Record_Type (Node18)
583 -- Present in protected and task types and subtypes. References the
584 -- entity for the corresponding record type constructed by the expander
585 -- (see Exp_Ch9). This type is used to represent values of the task type.
587 -- Corresponding_Remote_Type (Node22)
588 -- Present in record types that describe the fat pointer structure for
589 -- Remote_Access_To_Subrogram types. References the original access type.
591 -- CR_Discriminant (Node23)
592 -- Present in discriminants of concurrent types. Denotes the homologous
593 -- discriminant of the corresponding record type. The CR_Discriminant is
594 -- created at the same time as the discriminal, and used to replace
595 -- occurrences of the discriminant within the type declaration.
597 -- Current_Use_Clause (Node25)
598 -- Present in packages. Indicates the use clause currently in scope
599 -- that makes the package use_visible. Used to detect redundant use
600 -- clauses for the same package.
602 -- Current_Value (Node9)
603 -- Present in E_Variable, E_Out_Parameter and E_In_Out_Parameter
604 -- entities. Set non-Empty if the (constant) current value of the
605 -- variable is known. This value is valid only for references from
606 -- the same sequential scope as the entity. The sequential scope
607 -- of an entity includes the immediate scope and any contained
608 -- scopes that are package specs, package bodies, or blocks (at
609 -- any nesting level). For convenience in coding, this field is
610 -- also present in other object entities (E_Loop_Parameter and
611 -- E_In_Parameter and E_Constant), but is not used to hold a
612 -- constant value, since value tracking is not needed in this case.
614 -- Another related use of this field is to record information
615 -- about the value obtained from an IF statement condition.
616 -- If the IF/ELSIF condition has the form "[NOT] OBJ RELOP VAL",
617 -- where OBJ is a reference to an entity with a Current_Value field,
618 -- RELOP is one of the six relational operators, and VAL is a compile-
619 -- time known value, then the Current_Value field if OBJ is set to
620 -- point to the N_If_Statement or N_Elsif_Part node of the relevant
621 -- construct. For more details on this usage, see the procedure
622 -- Exp_Util.Get_Current_Value_Condition.
624 -- Debug_Info_Off (Flag166)
625 -- Present in all entities. Set if a pragma Suppress_Debug_Info applies
626 -- to the entity, or if internal processing in the compiler determines
627 -- that suppression of debug information is desirable. Note that this
628 -- flag is only for use by the front end as part of the processing for
629 -- determining if Needs_Debug_Info should be set. The back end should
630 -- always test Needs_Debug_Info, it should never test Debug_Info_Off.
632 -- Debug_Renaming_Link (Node13)
633 -- Used to link the enumeration literal of a debug renaming declaration
634 -- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
635 -- details of the use of this field.
637 -- Declaration_Node (synthesized)
638 -- Applies to all entities. Returns the tree node for the declaration
639 -- that declared the entity. Normally this is just the Parent of the
640 -- entity. One exception arises with child units, where the parent of
641 -- the entity is a selected component or a defining program unit name.
642 -- Another exception is that if the entity is an incomplete type that
643 -- has been completed, then we obtain the declaration node denoted by
644 -- the full type, i.e. the full type declaration node.
646 -- Default_Expr_Function (Node21)
647 -- Present in parameters. It holds the entity of the parameterless
648 -- function that is built to evaluate the default expression if it is
649 -- more complex than a simple identifier or literal. For the latter
650 -- simple cases or if there is no default value, this field is Empty.
652 -- Default_Expressions_Processed (Flag108)
653 -- A flag in subprograms (functions, operators, procedures) and in
654 -- entries and entry families used to indicate that default expressions
655 -- have been processed and to avoid multiple calls to process the
656 -- default expressions (see Freeze.Process_Default_Expressions), which
657 -- would not only waste time, but also generate false error messages.
659 -- Default_Value (Node20)
660 -- Present in formal parameters. Points to the node representing the
661 -- expression for the default value for the parameter. Empty if the
662 -- parameter has no default value (which is always the case for OUT
663 -- and IN OUT parameters in the absence of errors).
665 -- Delay_Cleanups (Flag114)
666 -- Present in entities that have finalization lists (subprograms
667 -- blocks, and tasks). Set if there are pending generic body
668 -- instantiations for the corresponding entity. If this flag is
669 -- set, then generation of cleanup actions for the corresponding
670 -- entity must be delayed, since the insertion of the generic body
671 -- may affect cleanup generation (see Inline for further details).
673 -- Delay_Subprogram_Descriptors (Flag50)
674 -- Present in entities for which exception subprogram descriptors
675 -- are generated (subprograms, package declarations and package
676 -- bodies). Present if there are pending generic body instantiations
677 -- for the corresponding entity. If this flag is set, then generation
678 -- of the subprogram descriptor for the corresponding enities must
679 -- be delayed, since the insertion of the generic body may add entries
680 -- to the list of handlers.
682 -- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
683 -- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
684 -- a block (in which case Delay_Subprogram_Descriptors is set for the
685 -- containing subprogram). In addition Delay_Subprogram_Descriptors is
686 -- set for a library level package declaration or body which contains
687 -- delayed instantiations (in this case the descriptor refers to the
688 -- enclosing elaboration procedure).
690 -- Delta_Value (Ureal18)
691 -- Present in fixed and decimal types. Points to a universal real
692 -- that holds value of delta for the type, as given in the declaration
693 -- or as inherited by a subtype or derived type.
695 -- Dependent_Instances (Elist8)
696 -- Present in packages that are instances. Holds list of instances
697 -- of inner generics. Used to place freeze nodes for those instances
698 -- after that of the current one, i.e. after the corresponding generic
701 -- Depends_On_Private (Flag14)
702 -- Present in all type entities. Set if the type is private or if it
703 -- depends on a private type.
705 -- Designated_Type (synthesized)
706 -- Applies to access types. Returns the designated type. Differs
707 -- from Directly_Designated_Type in that if the access type refers
708 -- to an incomplete type, and the full type is available, then this
709 -- full type is returned instead of the incomplete type.
711 -- Digits_Value (Uint17)
712 -- Present in floating point types and subtypes and decimal types and
713 -- subtypes. Contains the Digits value specified in the declaration.
715 -- Directly_Designated_Type (Node20)
716 -- Present in access types. This field points to the type that is
717 -- directly designated by the access type. In the case of an access
718 -- type to an incomplete type, this field references the incomplete
719 -- type. Note that in the semantic processing, what is useful in
720 -- nearly all cases is the full type designated by the access type.
721 -- The function Designated_Type obtains this full type in the case of
722 -- access to an incomplete type.
724 -- Discard_Names (Flag88)
725 -- Present in types and exception entities. Set if pragma Discard_Names
726 -- applies to the entity. It is also set for declarative regions and
727 -- package specs for which a Discard_Names pragma with zero arguments
728 -- has been encountered. The purpose of setting this flag is to be able
729 -- to set the Discard_Names attribute on enumeration types declared
730 -- after the pragma within the same declarative region. This flag is
731 -- set to False if a Keep_Names pragma appears for an enumeration type.
733 -- Discriminal (Node17)
734 -- Present in discriminants (Discriminant formal: GNAT's first
735 -- coinage). The entity used as a formal parameter that corresponds
736 -- to a discriminant. See section "Handling of Discriminants" for
737 -- full details of the use of discriminals.
739 -- Discriminal_Link (Node10)
740 -- Present in discriminals (which have an Ekind of E_In_Parameter,
741 -- or E_Constant), points back to corresponding discriminant.
743 -- Discriminant_Checking_Func (Node20)
744 -- Present in components. Points to the defining identifier of the
745 -- function built by the expander returns a Boolean indicating whether
746 -- the given record component exists for the current discriminant
749 -- Discriminant_Constraint (Elist21)
750 -- Present in entities whose Has_Discriminants flag is set (concurrent
751 -- types, subtypes, record types and subtypes, private types and
752 -- subtypes, limited private types and subtypes and incomplete types).
753 -- It is an error to reference the Discriminant_Constraint field if
754 -- Has_Discriminants is False.
756 -- If the Is_Constrained flag is set, Discriminant_Constraint points
757 -- to an element list containing the discriminant constraints in the
758 -- same order in which the discriminants are declared.
760 -- If the Is_Constrained flag is not set but the discriminants of the
761 -- unconstrained type have default initial values then this field
762 -- points to an element list giving these default initial values in
763 -- the same order in which the discriminants are declared. Note that
764 -- in this case the entity cannot be a tagged record type, because
765 -- discriminants in this case cannot have defaults.
767 -- If the entity is a tagged record implicit type, then this field is
768 -- inherited from the first subtype (so that the itype is subtype
769 -- conformant with its first subtype, which is needed when the first
770 -- subtype overrides primitive operations inherited by the implicit
773 -- In all other cases Discriminant_Constraint contains the empty
774 -- Elist (ie it is initialized with a call to New_Elmt_List).
776 -- Discriminant_Default_Value (Node20)
777 -- Present in discriminants. Points to the node representing the
778 -- expression for the default value of the discriminant. Set to
779 -- Empty if the discriminant has no default value.
781 -- Discriminant_Number (Uint15)
782 -- Present in discriminants. Gives the ranking of a discriminant in
783 -- the list of discriminants of the type, i.e. a sequential integer
784 -- index starting at 1 and ranging up to Number_Discriminants.
786 -- DTC_Entity (Node16)
787 -- Present in function and procedure entities. Set to Empty unless
788 -- the subprogram is dispatching in which case it references the
789 -- Dispatch Table pointer Component. That is to say the component _tag
790 -- for regular Ada tagged types, for CPP_Class types and their
791 -- descendants this field points to the component entity in the record
792 -- that is the Vtable pointer for the Vtable containing the entry that
793 -- references the subprogram.
795 -- DT_Entry_Count (Uint15)
796 -- Present in E_Component entities. Only used for component marked
797 -- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
799 -- DT_Position (Uint15)
800 -- Present in function and procedure entities which are dispatching
801 -- (should not be referenced without first checking that flag
802 -- Is_Dispatching_Operation is True). Contains the offset into
803 -- the Vtable for the entry that references the subprogram.
806 -- Present in all entities. Contains a value of the enumeration type
807 -- Entity_Kind declared in a subsequent section in this spec.
809 -- Elaboration_Entity (Node13)
810 -- Present in generic and non-generic package and subprogram
811 -- entities. This is a boolean entity associated with the unit that
812 -- is initiallly set to False, and is set True when the unit is
813 -- elaborated. This is used for two purposes. First, it is used to
814 -- implement required access before elaboration checks (the flag
815 -- must be true to call a subprogram at elaboration time). Second,
816 -- it is used to guard against repeated execution of the generated
819 -- Note that we always allocate this flag, and set this field, but
820 -- we do not always actually use it. It is only used if it is needed
821 -- for access-before-elaboration use (see Elaboration_Entity_Required
822 -- flag) or if either the spec or the body has elaboration code. If
823 -- neither of these two conditions holds, then the entity is still
824 -- allocated (since we don't know early enough whether or not there
825 -- is elaboration code), but is simply not used for any purpose.
827 -- Elaboration_Entity_Required (Flag174)
828 -- Present in generics and non-generic package and subprogram
829 -- entities. Set only if Elaboration_Entity is non-Empty to indicate
830 -- that the boolean is required to be set even if there is no other
831 -- elaboration code. This occurs when the Elaboration_Entity flag
832 -- is used for required access-before-elaboration checking. If the
833 -- flag is only for preventing multiple execution of the elaboration
834 -- code, then if there is no other elaboration code, obviously there
835 -- is no need to set the flag.
837 -- Enclosing_Dynamic_Scope (synthesized)
838 -- Appliesa to all entities. Returns the closest dynamic scope in which
839 -- the entity is declared or Standard_Standard for library-level entities
841 -- Enclosing_Scope (Node18)
842 -- Present in labels. Denotes the innermost enclosing construct that
843 -- contains the label. Identical to the scope of the label, except for
844 -- labels declared in the body of an accept statement, in which case the
845 -- entry_name is the Enclosing_Scope. Used to validate goto's within
846 -- accept statements.
848 -- Entry_Accepted (Flag152)
849 -- Present in E_Entry and E_Entry_Family entities. Set if there is
850 -- at least one accept for this entry in the task body. Used to
851 -- generate warnings for missing accepts.
853 -- Entry_Bodies_Array (Node15)
854 -- Present in protected types for which Has_Entries is true.
855 -- This is the defining identifier for the array of entry body
856 -- action procedures and barrier functions used by the runtime to
857 -- execute the user code associated with each entry.
859 -- Entry_Cancel_Parameter (Node23)
860 -- Present in blocks. This only applies to a block statement for
861 -- which the Is_Asynchronous_Call_Block flag is set. It
862 -- contains the defining identifier of an object that must be
863 -- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
864 -- call in the cleanup handler added to the block by
865 -- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
866 -- object for task entry calls and a Communications_Block object
867 -- in the case of protected entry calls. In both cases the objects
868 -- are declared in outer scopes to this block.
870 -- Entry_Component (Node11)
871 -- Present in formal parameters (in, in out and out parameters). Used
872 -- only for formals of entries. References the corresponding component
873 -- of the entry parameter record for the entry.
875 -- Entry_Formal (Node16)
876 -- Present in components of the record built to correspond to entry
877 -- parameters. This field points from the component to the formal. It
878 -- is the back pointer corresponding to Entry_Component.
880 -- Entry_Index_Constant (Node18)
881 -- Present in an entry index parameter. This is an identifier that
882 -- eventually becomes the name of a constant representing the index
883 -- of the entry family member whose entry body is being executed. Used
884 -- to expand references to the entry index specification identifier.
886 -- Entry_Index_Type (synthesized)
887 -- Applies to an entry family. Denotes Etype of the subtype indication
888 -- in the entry declaration. Used to resolve the index expression in an
889 -- accept statement for a member of the family, and in the prefix of
890 -- 'COUNT when it applies to a family member.
892 -- Entry_Parameters_Type (Node15)
893 -- Present in entries. Points to the access-to-record type that is
894 -- constructed by the expander to hold a reference to the parameter
895 -- values. This reference is manipulated (as an address) by the
896 -- tasking runtime. The designated record represents a packaging
897 -- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
898 -- for further details). Entry_Parameters_Type is Empty if the entry
899 -- has no parameters.
901 -- Enumeration_Pos (Uint11)
902 -- Present in enumeration literals. Contains the position number
903 -- corresponding to the value of the enumeration literal.
905 -- Enumeration_Rep (Uint12)
906 -- Present in enumeration literals. Contains the representation that
907 -- corresponds to the value of the enumeration literal. Note that
908 -- this is normally the same as Enumeration_Pos except in the presence
909 -- of representation clauses, where Pos will still represent the
910 -- position of the literal within the type and Rep will have be the
911 -- value given in the representation clause.
913 -- Enumeration_Rep_Expr (Node22)
914 -- Present in enumeration literals. Points to the expression in an
915 -- associated enumeration rep clause that provides the representation
916 -- value for this literal. Empty if no enumeration rep clause for this
917 -- literal (or if rep clause does not have an entry for this literal,
918 -- an error situation). This is also used to catch duplicate entries
919 -- for the same literal.
921 -- Enum_Pos_To_Rep (Node23)
922 -- Present in enumeration types (but not enumeration subtypes). Set to
923 -- Empty unless the enumeration type has a non-standard representation
924 -- (i.e. at least one literal has a representation value different from
925 -- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
926 -- array constructed when the type is frozen that maps Pos values to
927 -- corresponding Rep values. The index type of this array is Natural,
928 -- and the component type is a suitable integer type that holds the
929 -- full range of representation values.
931 -- Equivalent_Type (Node18)
932 -- Present in class wide types and subtypes, access to protected
933 -- subprogram types, and in exception_types. For a classwide type, it
934 -- is always Empty. For a class wide subtype, it points to an entity
935 -- created by the expander which gives Gigi an easily understandable
936 -- equivalent of the class subtype with a known size (given by an
937 -- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
938 -- details. For E_exception_type, this points to the record containing
939 -- the data necessary to represent exceptions (for further details, see
940 -- System.Standard_Library. For access_to_protected subprograms, it
941 -- denotes a record that holds pointers to the operation and to the
942 -- protected object. For remote Access_To_Subprogram types, it denotes
943 -- the record that is the fat pointer representation of an RAST.
946 -- Present in all types and subtypes, and also for components, constants,
947 -- and variables. Contains the Object_Size of the type or of the object.
948 -- A value of zero indicates that the value is not yet known.
950 -- For the case of components where a component clause is present, the
951 -- value is the value from the component clause, which must be non-
952 -- negative (but may be zero, which is acceptable for the case of
953 -- a type with only one possible value). It is also possible for Esize
954 -- of a component to be set without a component clause present, which
955 -- means that the component size is specified, but not the position.
956 -- See also RM_Size and the section on "Handling of Type'Size Values".
957 -- During gigi processing, the value is back annotated for all zero
958 -- values, so that after the call to gigi, the value is properly set.
961 -- Present in all entities. Represents the type of the entity, which
962 -- is itself another entity. For a type entity, points to the parent
963 -- type for a derived type, or if the type is not derived, points to
964 -- itself. For a subtype entity, Etype points to the base type. For
965 -- a class wide type, points to the parent type. For a subprogram or
966 -- subprogram type, Etype has the return type of a function or is set
967 -- to Standard_Void_Type to represent a procedure.
969 -- Exception_Code (Uint22)
970 -- Present in exception entitites. Set to zero unless either an
971 -- Import_Exception or Export_Exception pragma applies to the
972 -- pragma and specifies a Code value. See description of these
973 -- pragmas for details. Note that this field is relevant only if
974 -- Is_VMS_Exception is set.
976 -- Extra_Formal (Node15)
977 -- Present in formal parameters in the non-generic case. Certain
978 -- parameters require extra implicit information to be passed
979 -- (e.g. the flag indicating if an unconstrained variant record
980 -- argument is constrained, and the accessibility level for
981 -- access parameters. See description of Extra_Constrained,
982 -- Extra_Accessibility fields for further details. Extra formal
983 -- parameters are constructed to represent these values, and
984 -- chained to the end of the list of formals using the
985 -- Extra_Formal field (i.e. the Extra_Formal field of the last
986 -- "real" formal points to the first extra formal, and the
987 -- Extra_Formal field of each extra formal points to the next
988 -- one, with Empty indicating the end of the list of extra
991 -- Extra_Accessibility (Node13)
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 accessibility check is required, then
995 -- an extra formal of type Natural is created (see description
996 -- of field Extra_Formal), and the Extra_Accessibility field of
997 -- the formal parameter points to the entity for this extra
998 -- formal. Also present in variables when compiling receiving
999 -- stubs. In this case, a non Empty value means that this
1000 -- variable's accessibility depth has been transmitted by the
1001 -- caller and must be retrieved through the entity designed by
1002 -- this field instead of being computed.
1004 -- Extra_Constrained (Node23)
1005 -- Present in formal parameters in the non-generic case if
1006 -- expansion is active. Normally Empty, but if a parameter is
1007 -- one for which a dynamic indication of its constrained status
1008 -- is required, then an extra formal of type Boolean is created
1009 -- (see description of field Extra_Formal), and the
1010 -- Extra_Constrained field of the formal parameter points to the
1011 -- entity for this extra formal. Also present in variables when
1012 -- compiling receiving stubs. In this case, a non empty value
1013 -- means that this variable's constrained status has been
1014 -- transmitted by the caller and must be retrieved through the
1015 -- entity designed by this field instead of being computed.
1017 -- Finalization_Chain_Entity (Node19)
1018 -- Present in scopes which can have finalizable entities (blocks,
1019 -- functions, procedures, tasks, entries). When this field is empty it
1020 -- means that there are no finalization actions to perform on exit of the
1021 -- scope. When this field contains 'Error', it means that no
1022 -- finalization actions should happen at this level and the
1023 -- finalization chain of a parent scope shall be used (??? this is
1024 -- an improper use of 'Error' and should be changed). otherwise it
1025 -- contains an entity of type Finalizable_Ptr that is the head of the
1026 -- list of objects to finalize on exit. See "Finalization Management"
1027 -- section in exp_ch7.adb for more details.
1029 -- Finalize_Storage_Only (Flag158) [base type only]
1030 -- Present in all types. Set on direct controlled types to which a
1031 -- valid Finalize_Storage_Only pragma applies. This flag is also set on
1032 -- composite types when they have at least one controlled component and
1033 -- all their controlled components are Finalize_Storage_Only. It is also
1034 -- inherited by type derivation except for direct controlled types where
1035 -- the Finalize_Storage_Only pragma is required at each level of
1038 -- First_Component (synthesized)
1039 -- Applies to record types. Returns the first component by following
1040 -- the chain of declared entities for the record until a component
1041 -- is found (one with an Ekind of E_Component). The discriminants are
1042 -- skipped. If the record is null, then Empty is returned.
1044 -- First_Discriminant (synthesized)
1045 -- Applies to types with discriminants. The discriminants are the
1046 -- first entities declared in the type, so normally this is equivalent
1047 -- to First_Entity. The exception arises for tagged types, where the
1048 -- tag itself is prepended to the front of the entity chain, so the
1049 -- First_Discriminant function steps past the tag if it is present.
1051 -- First_Entity (Node17)
1052 -- Present in all entities which act as scopes to which a list of
1053 -- associated entities is attached (blocks, class subtypes and types,
1054 -- entries, functions, loops, packages, procedures, protected objects,
1055 -- record types and subtypes, private types, task types and subtypes).
1056 -- Points to a list of associated entities using the Next_Entity field
1057 -- as a chain pointer with Empty marking the end of the list.
1059 -- First_Formal (synthesized)
1060 -- Applies to subprograms and subprogram types, and also in entries
1061 -- and entry families. Returns first formal of the subprogram or entry.
1062 -- The formals are the first entities declared in a subprogram or in
1063 -- a subprogram type (the designated type of an Access_To_Subprogram
1064 -- definition) or in an entry.
1066 -- First_Index (Node17)
1067 -- Present in array types and subtypes and in string types and subtypes.
1068 -- By introducing implicit subtypes for the index constraints, we have
1069 -- the same structure for constrained and unconstrained arrays, subtype
1070 -- marks and discrete ranges are both represented by a subtype. This
1071 -- function returns the tree node corresponding to an occurrence of the
1072 -- first index (NOT the entity for the type). Subsequent indexes are
1073 -- obtained using Next_Index. Note that this field is present for the
1074 -- case of string literal subtypes, but is always Empty.
1076 -- First_Literal (Node17)
1077 -- Present in all enumeration types, including character and boolean
1078 -- types. This field points to the first enumeration literal entity
1079 -- for the type (i.e. it is set to First (Literals (N)) where N is
1080 -- the enumeration type definition node. A special case occurs with
1081 -- standard character and wide character types, where this field is
1082 -- Empty, since there are no enumeration literal lists in these cases.
1083 -- Note that this field is set in enumeration subtypes, but it still
1084 -- points to the first literal of the base type in this case.
1086 -- First_Optional_Parameter (Node14)
1087 -- Present in (non-generic) function and procedure entities. Set to a
1088 -- non-null value only if a pragma Import_Function, Import_Procedure
1089 -- or Import_Valued_Procedure specifies a First_Optional_Parameter
1090 -- argument, in which case this field points to the parameter entity
1091 -- corresponding to the specified parameter.
1093 -- First_Private_Entity (Node16)
1094 -- Present in all entities containing private parts (packages,
1095 -- protected types and subtypes, task types and subtypes). The
1096 -- entities on the entity chain are in order of declaration, so the
1097 -- entries for private entities are at the end of the chain. This
1098 -- field points to the first entity for the private part. It is
1099 -- Empty if there are no entities declared in the private part or
1100 -- if there is no private part.
1102 -- First_Rep_Item (Node6)
1103 -- Present in all entities. If non-empty, points to a linked list of
1104 -- representation pragmas nodes and representation clause nodes that
1105 -- apply to the entity, linked using Next_Rep_Item, with Empty marking
1106 -- the end of the list. In the case of derived types and subtypes, the
1107 -- new entity inherits the chain at the point of declaration. This
1108 -- means that it is possible to have multiple instances of the same
1109 -- kind of rep item on the chain, in which case it is the first one
1110 -- that applies to the entity.
1112 -- For most representation items, the representation information is
1113 -- reflected in other fields and flags in the entity. For example if
1114 -- a record representation clause is present, the component entities
1115 -- reflect the specified information. However, there are some items
1116 -- that are only reflected in the chain. These include:
1118 -- Alignment attribute definition clause
1119 -- Machine_Attribute pragma
1120 -- Link_Alias pragma
1121 -- Link-Section pragma
1122 -- Weak_External pragma
1124 -- If any of these items are present, then the flag Has_Gigi_Rep_Item
1125 -- is set, indicating that Gigi should search the chain.
1127 -- Other representation items are included in the chain so that error
1128 -- messages can easily locate the relevant nodes for posting errors.
1129 -- Note in particular that size clauses are present only for this
1130 -- purpose, and should only be accessed if Has_Size_Clause is set.
1132 -- First_Stored_Discriminant (synthesized)
1133 -- Applies to types with discriminants. Gives the first discriminant
1134 -- stored in the object. In many cases, these are the same as the
1135 -- normal visible discriminants for the type, but in the case of
1136 -- renamed discriminants, this is not always the case.
1138 -- For tagged types, and untagged types which are root types or
1139 -- derived types but which do not rename discriminants in their
1140 -- root type, the stored discriminants are the same as the actual
1141 -- discriminants of the type, and hence this function is the same
1142 -- as First_Discriminant.
1144 -- For derived non-tagged types that rename discriminants in the root
1145 -- type this is the first of the discriminants that occurr in the
1146 -- root type. To be precise, in this case stored discriminants are
1147 -- entities attached to the entity chain of the derived type which
1148 -- are a copy of the discriminants of the root type. Furthermore their
1149 -- Is_Completely_Hidden flag is set since although they are actually
1150 -- stored in the object, they are not in the set of discriminants that
1151 -- is visble in the type.
1153 -- For derived untagged types, stored discriminants are the real
1154 -- discriminants from Gigi's standpoint, i.e. those that will be
1155 -- stored in actual objects of the type.
1157 -- First_Subtype (synthesized)
1158 -- Applies to all types and subtypes. For types, yields the first
1159 -- subtype of the type. For subtypes, yields the first subtype of
1160 -- the base type of the subtype.
1162 -- Freeze_Node (Node7)
1163 -- Present in all entities. If there is an associated freeze node for
1164 -- the entity, this field references this freeze node. If no freeze
1165 -- node is associated with the entity, then this field is Empty. See
1166 -- package Freeze for further details.
1168 -- From_With_Type (Flag159)
1169 -- Present in package and type entities. Indicates that the entity
1170 -- appears in a With_Type clause in the context of some other unit,
1171 -- either as the prefix (which must be a package), or as a type name.
1172 -- The package can only be used to retrieve such a type, and the type
1173 -- can be used only in component declarations and access definitions.
1174 -- The With_Type clause is used to construct mutually recursive
1175 -- types, i.e. record types (Java classes) that hold pointers to each
1176 -- other. If such a type is an access type, it has no explicit freeze
1177 -- node, so that the back-end does not attempt to elaborate it.
1178 -- Currently this flag is also used to implement Ada 2005 (AI-50217).
1179 -- It will be renamed to From_Limited_With after removal of the current
1180 -- GNAT with_type clause???
1182 -- Full_View (Node11)
1183 -- Present in all type and subtype entities and in deferred constants.
1184 -- References the entity for the corresponding full type declaration.
1185 -- For all types other than private and incomplete types, this field
1186 -- always contains Empty. See also Underlying_Type.
1188 -- Function_Returns_With_DSP (Flag169)
1189 -- Present in all subprogram entities, and type entities for access
1190 -- to subprogram values. Set True if the function (or referenced
1191 -- function in the case of an access value) returns with using the
1192 -- DSP (depressed stack pointer) approach. This can only be set
1193 -- True if Targparm.Functions_Return_By_DSP_On_Target is True and
1194 -- the function returns a value of a type whose size is not known
1197 -- Generic_Homonym (Node11)
1198 -- Present in generic packages. The generic homonym is the entity of
1199 -- a renaming declaration inserted in every generic unit. It is used
1200 -- to resolve the name of a local entity that is given by a qualified
1201 -- name, when the generic entity itself is hidden by a local name.
1203 -- Generic_Renamings (Elist23)
1204 -- Present in package and subprogram instances. Holds mapping that
1205 -- associates generic parameters with the corresponding instances, in
1206 -- those cases where the instance is an entity.
1208 -- Handler_Records (List10)
1209 -- Present in subprogram and package entities. Points to a list of
1210 -- identifiers referencing the handler record entities for the
1211 -- corresponding unit.
1213 -- Has_Aliased_Components (Flag135) [implementation base type only]
1214 -- Present in array type entities. Indicates that the component type
1215 -- of the array is aliased.
1217 -- Has_Alignment_Clause (Flag46)
1218 -- Present in all type entities and objects. Indicates if an alignment
1219 -- clause has been given for the entity. If set, then Alignment_Clause
1220 -- returns the N_Attribute_Definition node for the alignment attribute
1221 -- definition clause. Note that it is possible for this flag to be False
1222 -- even when Alignment_Clause returns non_Empty (this happens in the case
1223 -- of derived type declarations).
1225 -- Has_All_Calls_Remote (Flag79)
1226 -- Present in all library unit entities. Set true if the library unit
1227 -- has an All_Calls_Remote pragma. Note that such entities must also
1228 -- be RCI entities, so the flag Is_Remote_Call_Interface will always
1229 -- be set if this flag is set.
1231 -- Has_Anon_Block_Suffix (Flag201)
1232 -- Present in all entities. Set if the entity is nested within one or
1233 -- more anonymous blocks and the Chars field contains a name with an
1234 -- anonymous block suffix (see Exp_Dbug for furthert details).
1236 -- Has_Atomic_Components (Flag86) [implementation base type only]
1237 -- Present in all types and objects. Set only for an array type or
1238 -- an array object if a valid pragma Atomic_Components applies to the
1239 -- type or object. Note that in the case of an object, this flag is
1240 -- only set on the object if there was an explicit pragma for the
1241 -- object. In other words, the proper test for whether an object has
1242 -- atomic components is to see if either the object or its base type
1243 -- has this flag set. Note that in the case of a type, the pragma will
1244 -- be chained to the rep item chain of the first subtype in the usual
1247 -- Has_Attach_Handler (synthesized)
1248 -- Applies to record types that are constructed by the expander to
1249 -- represent protected types. Returns True if there is at least one
1250 -- Attach_Handler pragma in the corresponding specification.
1252 -- Has_Biased_Representation (Flag139)
1253 -- Present in discrete types (where it applies to the type'size value),
1254 -- and to objects (both stand-alone and components), where it applies to
1255 -- the size of the object from a size or record component clause. In
1256 -- all cases it indicates that the size in question is smaller than
1257 -- would normally be required, but that the size requirement can be
1258 -- satisfied by using a biased representation, in which stored values
1259 -- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
1260 -- reduce the required size. For example, a type with a range of 1..2
1261 -- takes one bit, using 0 to represent 1 and 1 to represent 2.
1263 -- Note that in the object and component cases, the flag is only set
1264 -- if the type is unbiased, but the object specifies a smaller size
1265 -- than the size of the type, forcing biased representation for the
1266 -- object, but the subtype is still an unbiased type.
1268 -- Has_Completion (Flag26)
1269 -- Present in all entities that require a completion (functions,
1270 -- procedures, private types, limited private types, incomplete types,
1271 -- constants and packages that require a body). The flag is set if the
1272 -- completion has been encountered and analyzed.
1274 -- Has_Completion_In_Body (Flag71)
1275 -- Present in "Taft amendment types" that is to say incomplete types
1276 -- whose full declaration appears in the package body.
1278 -- Has_Complex_Representation (Flag140) [implementation base type only]
1279 -- Present in all type entities. Set only for a record base type to
1280 -- which a valid pragma Complex_Representation applies.
1282 -- Has_Component_Size_Clause (Flag68) [implementation base type only]
1283 -- Present in all type entities. Set if a component size clause is
1284 -- present for the given type. Note that this flag can be False even
1285 -- if Component_Size is non-zero (happens in the case of derived types).
1287 -- Has_Constrained_Partial_View (Flag187)
1288 -- Present in private type and their completions, when the private
1289 -- type has no discriminants and the full view has discriminants with
1290 -- defaults. In Ada 2005 heap-allocated objects of such types are not
1291 -- constrained, and can change their discriminants with full assignment.
1293 -- Has_Contiguous_Rep (Flag181)
1294 -- Present in enumeration types. True if the type as a representation
1295 -- clause whose entries are successive integers.
1297 -- Has_Controlling_Result (Flag98)
1298 -- Present in E_Function entities. True if The function is a primitive
1299 -- function of a tagged type which can dispatch on result
1301 -- Has_Controlled_Component (Flag43) [base type only]
1302 -- Present in all entities. Set only for composite type entities which
1303 -- contain a component that either is a controlled type, or itself
1304 -- contains controlled component (i.e. either Has_Controlled_Component
1305 -- or Is_Controlled is set for at least one component).
1307 -- Has_Convention_Pragma (Flag119)
1308 -- Present in an entity for which a Convention, Import, or Export
1309 -- pragma has been given. Used to prevent more than one such pragma
1310 -- appearing for a given entity (RM B.1(45)).
1312 -- Has_Delayed_Freeze (Flag18)
1313 -- Present in all entities. Set to indicate that an explicit freeze
1314 -- node must be generated for the entity at its freezing point. See
1315 -- separate section ("Delayed Freezing and Elaboration") for details.
1317 -- Has_Discriminants (Flag5)
1318 -- Present in all types and subtypes. For types that are allowed to have
1319 -- discriminants (record types and subtypes, task types and subtypes,
1320 -- protected types and subtypes, private types, limited private types,
1321 -- and incomplete types), indicates if the corresponding type or subtype
1322 -- has a known discriminant part. Always false for all other types.
1324 -- Has_Entries (synthesized)
1325 -- Applies to concurrent types. True if any entries are declared
1326 -- within the task or protected definition for the type.
1328 -- Has_Enumeration_Rep_Clause (Flag66)
1329 -- Present in enumeration types. Set if an enumeration representation
1330 -- clause has been given for this enumeration type. Used to prevent more
1331 -- than one enumeration representation clause for a given type. Note
1332 -- that this does not imply a representation with holes, since the rep
1333 -- clause may merely confirm the default 0..N representation.
1335 -- Has_External_Tag_Rep_Clause (Flag110)
1336 -- Present in tagged types. Set if an external_tag rep. clause has been
1337 -- given for this type. Use to avoid the generation of the default
1340 -- Has_Exit (Flag47)
1341 -- Present in loop entities. Set if the loop contains an exit statement.
1343 -- Has_Foreign_Convention (synthesized)
1344 -- Applies to all entities. Determines if the Convention for the
1345 -- entity is a foreign convention (i.e. is other than Convention_Ada,
1346 -- Convention_Intrinsic, Convention_Entry or Convention_Protected).
1348 -- Has_Forward_Instantiation (Flag175)
1349 -- Present in package entities. Set true for packages that contain
1350 -- instantiations of local generic entities, before the corresponding
1351 -- generic body has been seen. If a package has a forward instantiation,
1352 -- we cannot inline subprograms appearing in the same package because
1353 -- the placement requirements of the instance will conflict with the
1354 -- linear elaboration of front-end inlining.
1356 -- Has_Fully_Qualified_Name (Flag173)
1357 -- Present in all entities. Set True if the name in the Chars field
1358 -- has been replaced by the fully qualified name, as used for debug
1359 -- output. See Exp_Dbug for a full description of the use of this
1360 -- flag and also the related flag Has_Qualified_Name.
1362 -- Has_Gigi_Rep_Item (Flag82)
1363 -- This flag is set if the rep item chain (referenced by First_Rep_Item
1364 -- and linked through the Next_Rep_Item chain) contains a representation
1365 -- item that needs to be specially processed by Gigi, i.e. one of the
1368 -- Machine_Attribute pragma
1369 -- Linker_Alias pragma
1370 -- Linker_Section pragma
1371 -- Linker_Constructor pragma
1372 -- Linker_Destructor pragma
1373 -- Weak_External pragma
1375 -- If this flag is set, then Gigi should scan the rep item chain to
1376 -- process any of these items that appear. At least one such item will
1379 -- Has_Homonym (Flag56)
1380 -- Present in all entities. Set if an entity has a homonym in the same
1381 -- scope. Used by Gigi to generate unique names for such entities.
1383 -- Has_Interrupt_Handler (synthesized)
1384 -- Applies to all protected type entities. Set if the protected type
1385 -- definition contains at least one procedure to which a pragma
1386 -- Interrupt_Handler applies.
1388 -- Has_Machine_Radix_Clause (Flag83)
1389 -- Present in decimal types and subtypes, set if a Machine_Radix
1390 -- representation clause is present. This flag is used to detect
1391 -- the error of multiple machine radix clauses for a single type.
1393 -- Has_Master_Entity (Flag21)
1394 -- Present in entities that can appear in the scope stack (see spec
1395 -- of Sem). It is set if a task master entity (_master) has been
1396 -- declared and initialized in the corresponding scope.
1398 -- Has_Missing_Return (Flag142)
1399 -- Present in functions and generic functions. Set if there is one or
1400 -- more missing return statements in the function. This is used to
1401 -- control wrapping of the body in Exp_Ch6 to ensure that the program
1402 -- error exeption is correctly raised in this case at runtime.
1404 -- Has_Nested_Block_With_Handler (Flag101)
1405 -- Present in scope entities. Set if there is a nested block within the
1406 -- scope that has an exception handler and the two scopes are in the
1407 -- same procedure. This is used by the backend for controlling certain
1408 -- optimizations to ensure that they are consistent with exceptions.
1409 -- See documentation in Gigi for further details.
1411 -- Has_Non_Standard_Rep (Flag75) [implementation base type only]
1412 -- Present in all type entities. Set when some representation clause
1413 -- or pragma causes the representation of the item to be significantly
1414 -- modified. In this category are changes of small or radix for a
1415 -- fixed-point type, change of component size for an array, and record
1416 -- or enumeration representation clauses, as well as packed pragmas.
1417 -- All other representation clauses (e.g. Size and Alignment clauses)
1418 -- are not considered to be significant since they do not affect
1419 -- stored bit patterns.
1421 -- Has_Object_Size_Clause (Flag172)
1422 -- Present in entities for types and subtypes. Set if an Object_Size
1423 -- clause has been processed for the type Used to prevent multiple
1424 -- Object_Size clauses for a given entity.
1426 -- Has_Per_Object_Constraint (Flag154)
1427 -- Present in E_Component entities, true if the subtype of the
1428 -- component has a per object constraint. Per object constraints result
1429 -- from the following situations:
1431 -- 1. N_Attribute_Reference - when the prefix is the enclosing type and
1432 -- the attribute is Access.
1433 -- 2. N_Discriminant_Association - when the expression uses the
1434 -- discriminant of the enclosing type.
1435 -- 3. N_Index_Or_Discriminant_Constraint - when at least one of the
1436 -- individual constraints is a per object constraint.
1437 -- 4. N_Range - when the lower or upper bound uses the discriminant of
1438 -- the enclosing type.
1439 -- 5. N_Range_Constraint - when the range expression uses the
1440 -- discriminant of the enclosing type.
1442 -- Has_Persistent_BSS (Flag188)
1443 -- Present in all entities. Set True for entities to which a valid
1444 -- pragma Persistent_BSS applies. Note that although the pragma is
1445 -- only meaningful for objects, we set it for all entities in a unit
1446 -- to which the pragma applies, as well as the unit entity itself, for
1447 -- convenience in propagating the flag to contained entities.
1449 -- Has_Pragma_Controlled (Flag27) [implementation base type only]
1450 -- Present in access type entities. It is set if a pragma Controlled
1451 -- applies to the access type.
1453 -- Has_Pragma_Elaborate_Body (Flag150)
1454 -- Present in all entities. Set in compilation unit entities if a
1455 -- pragma Elaborate_Body applies to the compilation unit.
1457 -- Has_Pragma_Inline (Flag157)
1458 -- Present in all entities. Set for functions and procedures for which
1459 -- a pragma Inline or Inline_Always applies to the subprogram. Note
1460 -- that this flag can be set even if Is_Inlined is not set. This
1461 -- happens for pragma Inline (if Inline_Active is False). In other
1462 -- words, the flag Has_Pragma_Inline represents the formal semantic
1463 -- status, and is used for checking semantic correctness.
1464 -- The flag Is_Inlined indicates whether inlining is actually active
1467 -- Has_Pragma_Pack (Flag121) [implementation base type only]
1468 -- Present in all entities. It indicates that a valid pragma Pack was
1469 -- was given for the type. Note that this flag is not inherited by a
1470 -- derived type. See also the Is_Packed flag.
1472 -- Has_Pragma_Pure_Function (Flag179)
1473 -- Present in subprogram entities. It indicates that a valid pragma
1474 -- Pure_Function was given for the entity. In some cases, we need to
1475 -- know that Is_Pure was explicitly set using this pragma.
1477 -- Has_Pragma_Unreferenced (Flag180)
1478 -- Present in all entities. Set if a valid pragma Unreferenced applies
1479 -- to the pragma, indicating that no warning should be given if the
1480 -- entity has no references, but a warning should be given if it is
1481 -- in fact referenced.
1483 -- Has_Primitive_Operations (Flag120) [base type only]
1484 -- Present in all type entities. Set if at least one primitive operation
1485 -- is defined for the type.
1487 -- Has_Private_Ancestor (synthesized)
1488 -- Applies to all type and subtype entities. Returns True if at least
1489 -- one ancestor is private, and otherwise False if there are no private
1492 -- Has_Private_Declaration (Flag155)
1493 -- Present in all entities. Returns True if it is the defining entity
1494 -- of a private type declaration or its corresponding full declaration.
1495 -- This flag is thus preserved when the full and the partial views are
1496 -- exchanged, to indicate if a full type declaration is a completion.
1497 -- Used for semantic checks in E.4 (18), and elsewhere.
1499 -- Has_Qualified_Name (Flag161)
1500 -- Present in all entities. Set True if the name in the Chars field
1501 -- has been replaced by its qualified name, as used for debug output.
1502 -- See Exp_Dbug for a full description of qualification requirements.
1503 -- For some entities, the name is the fully qualified name, but there
1504 -- are exceptions. In particular, for local variables in procedures,
1505 -- we do not include the procedure itself or higher scopes. See also
1506 -- the flag Has_Fully_Qualified_Name, which is set if the name does
1507 -- indeed include the fully qualified name.
1509 -- Has_Record_Rep_Clause (Flag65) [implementation base type only]
1510 -- Present in record types. Set if a record representation clause has
1511 -- been given for this record type. Used to prevent more than one such
1512 -- clause for a given record type. Note that this is initially cleared
1513 -- for a derived type, even though the representation is inherited. See
1514 -- also the flag Has_Specified_Layout.
1516 -- Has_Recursive_Call (Flag143)
1517 -- Present in procedures. Set if a direct parameterless recursive call
1518 -- is detected while analyzing the body. Used to activate some error
1519 -- checks for infinite recursion.
1521 -- Has_Size_Clause (Flag29)
1522 -- Present in entities for types and objects. Set if a size clause is
1523 -- present for the entity. Used to prevent multiple Size clauses for a
1524 -- given entity. Note that it is always initially cleared for a derived
1525 -- type, even though the Size for such a type is inherited from a Size
1526 -- clause given for the parent type.
1528 -- Has_Small_Clause (Flag67)
1529 -- Present in ordinary fixed point types (but not subtypes). Indicates
1530 -- that a small clause has been given for the entity. Used to prevent
1531 -- multiple Small clauses for a given entity. Note that it is always
1532 -- initially cleared for a derived type, even though the Small for such
1533 -- a type is inherited from a Small clause given for the parent type.
1535 -- Has_Specified_Layout (Flag100) [implementation base type only]
1536 -- Present in all type entities. Set for a record type or subtype if
1537 -- the record layout has been specified by a record representation
1538 -- clause. Note that this differs from the flag Has_Record_Rep_Clause
1539 -- in that it is inherited by a derived type. Has_Record_Rep_Clause is
1540 -- used to indicate that the type is mentioned explicitly in a record
1541 -- representation clause, and thus is not inherited by a derived type.
1542 -- This flag is always False for non-record types.
1544 -- Has_Specified_Stream_Input (Flag190)
1545 -- Has_Specified_Stream_Output (Flag191)
1546 -- Has_Specified_Stream_Read (Flag192)
1547 -- Has_Specified_Stream_Write (Flag193)
1548 -- Present in all type and subtype entities. Set for a given view if the
1549 -- corresponding stream-oriented attribute has been defined by an
1550 -- attribute definition clause. When such a clause occurs, a TSS is set
1551 -- on the underlying full view; the flags are used to track visibility of
1552 -- the attribute definition clause for partial or incomplete views.
1554 -- Has_Storage_Size_Clause (Flag23) [implementation base type only]
1555 -- Present in task types and access types. It is set if a Storage_Size
1556 -- clause is present for the type. Used to prevent multiple clauses for
1557 -- one type. Note that this flag is initially cleared for a derived type
1558 -- even though the Storage_Size for such a type is inherited from a
1559 -- Storage_Size clause given for the parent type. Note that in the case
1560 -- of access types, this flag is present only in the root type, since a
1561 -- storage size clause cannot be given to a derived type.
1563 -- Has_Stream_Size_Clause (Flag184)
1564 -- This flag is set on types which have a Stream_Size clause attribute.
1565 -- Used to prevent multiple Stream_Size clauses for a given entity.
1567 -- Has_Subprogram_Descriptor (Flag93)
1568 -- This flag is set on entities for which zero-cost exception subprogram
1569 -- descriptors can be generated (subprograms and library level package
1570 -- declarations and bodies). It indicates that a subprogram descriptor
1571 -- has been generated, and is used to suppress generation of multiple
1572 -- descriptors (e.g. when instantiating generic bodies).
1574 -- Has_Task (Flag30) [base type only]
1575 -- Present in all type entities. Set on task types themselves, and also
1576 -- (recursively) on any composite type which has a component for which
1577 -- Has_Task is set. The meaning is that an allocator of such an object
1578 -- must create the required tasks. Note that the flag is not set on
1579 -- access types, even if they designate an object that Has_Task.
1581 -- Has_Unchecked_Union (Flag123) [base type only]
1582 -- Present in all type entities. Set on unchecked unions themselves
1583 -- and (recursively) on any composite type which has a component for
1584 -- which Has_Unchecked_Union is set. The meaning is that a comparison
1585 -- operation for the type is not permitted. Note that the flag is not
1586 -- set on access types, even if they designate an object that has
1587 -- the flag Has_Unchecked_Union set.
1589 -- Has_Unknown_Discriminants (Flag72)
1590 -- Present in all type entities. Types can have unknown discriminants
1591 -- either from their declaration or through type derivation. The use
1592 -- of this flag exactly meets the spec in RM 3.7(26). Note that all
1593 -- class-wide types are considered to have unknown discriminants.
1594 -- Note that both Has_Discriminants and Has_Unknown_Discriminants may
1595 -- be true for a type. Class-wide types and their subtypes have
1596 -- unknown discriminants and can have declared ones as well. Private
1597 -- types declared with unknown discriminants may have a full view that
1598 -- has explicit discriminants, and both flag will be set on the partial
1599 -- view, to insure that discriminants are properly inherited in certain
1602 -- Has_Volatile_Components (Flag87) [implementation base type only]
1603 -- Present in all types and objects. Set only for an array type or
1604 -- array object if a valid pragma Volatile_Components or a valid
1605 -- pragma Atomic_Components applies to the type or object. Note that
1606 -- in the case of an object, this flag is only set on the object if
1607 -- there was an explicit pragma for the object. In other words, the
1608 -- proper test for whether an object has volatile components is to
1609 -- see if either the object or its base type has this flag set. Note
1610 -- that in the case of a type the pragma will be chained to the rep
1611 -- item chain of the first subtype in the usual manner.
1613 -- Has_Xref_Entry (Flag182)
1614 -- This flag is set if an entity has an entry in the Xref information
1615 -- generated in ali files. This is true for all source entities in the
1616 -- extended main source file. It is also true of entities in other
1617 -- packages that are referenced directly or indirectly from the main
1618 -- source file (indirect reference occurs when the main source file
1619 -- references an entity with a type reference. See package Lib.Xref
1620 -- for further details).
1622 -- Hiding_Loop_Variable (Node8)
1623 -- Present in variables. Set only if a variable of a discrete type is
1624 -- hidden by a loop variable in the same local scope, in which case
1625 -- the Hiding_Loop_Variable field of the hidden variable points to
1626 -- the E_Loop_Parameter entity doing the hiding. Used in processing
1627 -- warning messages if the hidden variable turns out to be unused
1628 -- or is referenced without being set.
1631 -- Present in all entities. Link for list of entities that have the
1632 -- same source name and that are declared in the same or enclosing
1633 -- scopes. Homonyms in the same scope are overloaded. Used for name
1634 -- resolution and for the generation of debugging information.
1636 -- Implementation_Base_Type (synthesized)
1637 -- Applies to all types. Similar to Base_Type, but never returns a
1638 -- private type when applied to a non-private type. Instead in this
1639 -- case, it always returns the Underlying_Type of the base type, so that
1640 -- we still have a concrete type. Note: it is allowed to apply
1641 -- Implementation_Base_Type to other than a type, in which case it
1642 -- simply returns the entity unchanged.
1644 -- In_Package_Body (Flag48)
1645 -- Set on the entity that denotes the package (the defining occurrence
1646 -- of the package declaration) while analyzing and expanding the package
1647 -- body. Reset on completion of analysis/expansion.
1649 -- In_Private_Part (Flag45)
1650 -- Present in package entities. Flag is set to indicate that the
1651 -- private part is being analyzed. The flag is reset at the end of the
1652 -- package declaration.
1654 -- Inner_Instances (Elist23)
1655 -- Present in generic units. Contains element list of units that are
1656 -- instantiated within the given generic. Used to diagnose circular
1659 -- Interface_Name (Node21)
1660 -- Present in exceptions, functions, procedures, variables, constants,
1661 -- and packages. Set to Empty unless an export, import, or interface
1662 -- name pragma has explicitly specified an external name, in which
1663 -- case it references an N_String_Literal node for the specified
1664 -- external name. In the case of exceptions, the field is set by
1665 -- Import_Exception/Export_Exception (which can be used in OpenVMS
1666 -- versions only). Note that if this field is Empty, and Is_Imported
1667 -- or Is_Exported is set, then the default interface name is the name
1668 -- of the entity, cased in a manner that is appropriate to the system
1669 -- in use. Note that Interface_Name is ignored if an address clause
1670 -- is present (since it is meaningless in this case).
1672 -- An additional special case usage of this field is in JGNAT for
1673 -- E_Component and E_Discriminant. JGNAT allows these entities to
1674 -- be imported by specifying pragma Import within a component's
1675 -- containing record definition. This supports interfacing to
1676 -- object fields defined within Java classes, and such pragmas
1677 -- are generated by the jvm2ada binding generator tool whenever
1678 -- it processes classes with public object fields. A pragma Import
1679 -- for a component can define the External_Name of the imported
1680 -- Java field (which is generally needed, because Java names are
1684 -- Present in packages and types. Set when analyzing a use clause for
1685 -- the corresponding entity. Reset at end of corresponding declarative
1686 -- part. The flag on a type is also used to determine the visibility of
1687 -- the primitive operators of the type.
1689 -- Is_Abstract (Flag19)
1690 -- Present in all types, and also for functions and procedures. Set
1691 -- for abstract types and abstract subprograms.
1693 -- Is_Local_Anonymous_Access (Flag194)
1694 -- Present in access types. Set for an anonymous access type to indicate
1695 -- that the type is created for a record component with an access
1696 -- definition, an array component, or a stand-alone object. Such
1697 -- anonymous types have an accessibility level equal to that of the
1698 -- declaration in which they appear, unlike the anonymous access types
1699 -- that are created for access parameters and access discriminants.
1701 -- Is_Access_Constant (Flag69)
1702 -- Present in access types and subtypes. Indicates that the keyword
1703 -- constant was present in the access type definition.
1705 -- Is_Access_Type (synthesized)
1706 -- Applies to all entities, true for access types and subtypes
1708 -- Is_Ada_2005 (Flag185)
1709 -- Applies to all entities, true if a valid pragma Ada_05 applies to the
1710 -- entity, indicating that the entity is Ada 2005 only.
1712 -- Is_Aliased (Flag15)
1713 -- Present in objects whose declarations carry the keyword aliased,
1714 -- and on record components that have the keyword.
1716 -- Is_Always_Inlined (synthesized)
1717 -- Present in subprograms. True if there is a pragma Inline_Always for
1720 -- Is_AST_Entry (Flag132)
1721 -- Present in entry entities. Set if a valid pragma AST_Entry applies
1722 -- to the entry. This flag can only be set in OpenVMS versions of GNAT.
1723 -- Note: we also allow the flag to appear in entry families, but given
1724 -- the current implementation of the pragma AST_Entry, this flag will
1725 -- always be False in entry families.
1727 -- Is_Atomic (Flag85)
1728 -- Present in all type entities, and also in constants, components and
1729 -- variables. Set if a pragma Atomic or Shared applies to the entity.
1730 -- In the case of private and incomplete types, this flag is set in
1731 -- both the partial view and the full view.
1733 -- Is_Array_Type (synthesized)
1734 -- Applies to all entities, true for array types and subtypes
1736 -- Is_Asynchronous (Flag81)
1737 -- Present in all type entities and in procedure entities. Set
1738 -- if a pragma Asynchronous applies to the entity.
1740 -- Is_Bit_Packed_Array (Flag122) [implementation base type only]
1741 -- Present in all entities. This flag is set for a packed array
1742 -- type that is bit packed (i.e. the component size is known by the
1743 -- front end and is in the range 1-7, 9-15, 17-31, or 33-63). Is_Packed
1744 -- is always set if Is_Bit_Packed_Array is set, but it is possible for
1745 -- Is_Packed to be set without Is_Bit_Packed_Array for the case of an
1746 -- array having one or more index types that are enumeration types
1747 -- with non-standard enumeration representations.
1749 -- Is_Boolean_Type (synthesized)
1750 -- Applies to all entities, true for boolean types and subtypes,
1751 -- i.e. Standard.Boolean and all types ultimately derived from it.
1753 -- Is_By_Copy_Type (synthesized)
1754 -- Applies to all type entities. Returns true if the entity is
1755 -- a by copy type (RM 6.2(3)).
1757 -- Is_By_Reference_Type (synthesized)
1758 -- Applies to all type entities. True if the type is required to
1759 -- be passed by reference, as defined in (RM 6.2(4-9)).
1761 -- Is_Called (Flag102)
1762 -- Present in subprograms. Returns true if the subprogram is called
1763 -- in the unit being compiled or in a unit in the context. Used for
1766 -- Is_Character_Type (Flag63)
1767 -- Present in all entities, true for character types and subtypes,
1768 -- i.e. enumeration types that have at least one character literal.

1775 -- Applies to all entities, true for class wide types and subtypes
1777 -- Is_Class_Wide_Equivalent_Type (Flag35)
1778 -- Present in record types and subtypes. Set to True, if the type acts
1779 -- as a class-wide equivalent type, i.e. the Equivalent_Type field of
1780 -- some class-wide subtype entity references this record type.
1782 -- Is_Compilation_Unit (Flag149)
1783 -- Present in all entities. Set if the entity is a package or subprogram
1784 -- entity for a compilation unit other than a subunit (since we treat
1785 -- subunits as part of the same compilation operation as the ultimate
1786 -- parent, we do not consider them to be separate units for this flag).
1788 -- Is_Completely_Hidden (Flag103)
1789 -- A flag set on an E_Discriminant entity. This flag can be set only
1790 -- for girder discriminants of untagged types. When set, the entity
1791 -- is a girder discriminant of a derived untagged type which is not
1792 -- directly visible in the derived type because the derived type or
1793 -- one of its ancestors have renamed the discriminants in the root
1794 -- type. Note that there are girder discriminants which are not
1795 -- Completely_Hidden (e.g. the discriminants of a root type).
1797 -- Is_Composite_Type (synthesized)
1798 -- Applies to all entities, true for all composite types and
1799 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
1800 -- not both) is true of any type.
1802 -- Is_Concurrent_Record_Type (Flag20)
1803 -- Present in record types and subtypes. Set if the type was created
1804 -- by the expander to represent a task or protected type. For every
1805 -- concurrent type, such as record type is constructed, and task and
1806 -- protected objects are instances of this record type at runtime
1807 -- (Gigi will replace declarations of the concurrent type using the
1808 -- declarations of the corresponding record type). See package Exp_Ch9
1809 -- for further details.
1811 -- Is_Concurrent_Type (synthesized)
1812 -- Applies to all entities, true for task types and subtypes and
1813 -- for protected types and subtypes.
1815 -- Is_Constrained (Flag12)
1816 -- Present in types or subtypes which may have index, discriminant
1817 -- or range constraint (i.e. array types and subtypes, record types
1818 -- and subtypes, string types and subtypes, and all numeric types).
1819 -- Set if the type or subtype is constrained.
1821 -- Is_Constr_Subt_For_U_Nominal (Flag80)
1822 -- Present in all types and subtypes. Set true only for the constructed
1823 -- subtype of an object whose nominal subtype is unconstrained. Note
1824 -- that the constructed subtype itself will be constrained.
1826 -- Is_Constr_Subt_For_UN_Aliased (Flag141)
1827 -- This flag can only be set if Is_Constr_Subt_For_U_Nominal is set. It
1828 -- indicates that in addition the object concerned is aliased. This flag
1829 -- is used by Gigi to determine whether a template must be constructed.
1831 -- Is_Constructor (Flag76)
1832 -- Present in function and procedure entities. Set if a pragma
1833 -- CPP_Constructor applies to the subprogram.
1835 -- Is_Controlled (Flag42) [base type only]
1836 -- Present in all type entities. Indicates that the type is controlled,
1837 -- i.e. is either a descendant of Ada.Finalization.Controlled or of
1838 -- Ada.Finalization.Limited_Controlled.

1841 -- Present in all Formal_Kind entity. Marks the controlling parameters
1842 -- of dispatching operations.
1844 -- Is_CPP_Class (Flag74)
1845 -- Present in all type entities, set only for tagged and untagged
1846 -- record types to which the pragma CPP_Class has been applied.
1848 -- Is_Decimal_Fixed_Point_Type (synthesized)
1849 -- Applies to all type entities, true for decimal fixed point
1850 -- types and subtypes.
1852 -- Is_Derived_Type (synthesized)
1853 -- Applies to all type entities. Determine if given entity is a
1856 -- Is_Discrete_Type (synthesized)
1857 -- Applies to all entities, true for all discrete types and subtypes
1859 -- Is_Discrete__Or_Fixed_Point_Type (synthesized)
1860 -- Applies to all entities, true for all discrete types and subtypes
1861 -- and all fixed-point types and subtypes.
1863 -- Is_Discrim_SO_Function (Flag176)
1864 -- Present in all entities, set only in E_Function entities that Layout
1865 -- creates to compute discriminant-dependent dynamic size/offset values.
1867 -- Is_Dispatching_Operation (Flag6)
1868 -- Present in all entities. Set true for procedures, functions,
1869 -- generic procedures and generic functions if the corresponding
1870 -- operation is dispatching.
1872 -- Is_Dynamic_Scope (synthesized)
1873 -- Applies to all Entities. Returns True if the entity is a dynamic
1874 -- scope (i.e. a block, a subprogram a task_type or an entry).
1876 -- Is_Elementary_Type (synthesized)
1877 -- Applies to all entities, true for all elementary types and
1878 -- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
1879 -- not both) is true of any type.
1881 -- Is_Eliminated (Flag124)
1882 -- Present in type entities, subprogram entities, and object entities.
1883 -- Indicates that the corresponding entity has been eliminated by use
1884 -- of pragma Eliminate. Also used to mark subprogram entities whose
1885 -- declaration and body are within unreachable code that is removed.

1888 -- Present in all entities, true for enumeration types and subtypes
1890 -- Is_Entry (synthesized)

1894 -- Is_Entry_Formal (Flag52)
1895 -- Present in all entities. Set only for entry formals (which can
1896 -- only be in, in-out or out parameters). This flag is used to speed
1897 -- up the test for the need to replace references in Exp_Ch2.
1899 -- Is_Exported (Flag99)
1900 -- Present in all entities. Set if the entity is exported. For now we
1901 -- only allow the export of constants, exceptions, functions, procedures

1906 -- Present in all entities. True for first subtypes (RM 3.2.1(6)),
1907 -- i.e. the entity in the type declaration that introduced the type.
1908 -- This may be the base type itself (e.g. for record declarations and
1909 -- enumeration type declarations), or it may be the first subtype of
1910 -- an anonymous base type (e.g. for integer type declarations or
1911 -- constrained array declarations).
1913 -- Is_Fixed_Point_Type (synthesized)
1914 -- Applies to all entities, true for decimal and ordinary fixed
1915 -- point types and subtypes

1921 -- Applies to all entities, true for IN, IN OUT and OUT parameters
1923 -- Is_Formal_Subprogram (Flag111)
1924 -- Defined on all entities, true for generic formal subprograms.
1926 -- Is_For_Access_Subtype (Flag118)
1927 -- Present in E_Private_Subtype and E_Record_Subtype entities.
1928 -- Means the sole purpose of the type is to be designated by an
1929 -- Access_Subtype and hence should not be expanded into components
1930 -- because the type may not have been found or frozen yet.
1932 -- Is_Frozen (Flag4)
1933 -- Present in all type entities. Set if the type has been frozen.
1935 -- Is_Generic_Actual_Type (Flag94)
1936 -- Present in the subtype declaration that renames the generic formal

1938 -- within the instance.
1940 -- Is_Generic_Instance (Flag130)
1941 -- Present in all entities. Set to indicate that the entity is an
1942 -- instance of a generic unit.
1944 -- Is_Generic_Subprogram (synthesized)
1945 -- Applies to all entities. Yields True for a generic subprogram
1946 -- (generic function, generic subprogram), False for all other entities.
1948 -- Is_Generic_Type (Flag13)
1949 -- Present in all types and subtypes. Set for types which are generic
1950 -- formal types. Such types have an Ekind that corresponds to their
1951 -- classification, so the Ekind cannot be used to identify generic types.
1953 -- Is_Generic_Unit (synthesized)
1954 -- Applies to all entities. Yields True for a generic unit (generic
1955 -- package, generic function, generic procedure), and False for all
1958 -- Is_Hidden (Flag57)
1959 -- Present in all entities. Set true for all entities declared in the
1960 -- private part or body of a package. Also marks generic formals of a
1961 -- formal package declared without a box. For library level entities,
1962 -- this flag is set if the entity is not publicly visible.
1964 -- Is_Hidden_Open_Scope (Flag171)
1965 -- Present in all entities. Set true for a scope that contains the

1970 -- Present in all entities. Set if entity is immediately visible, i.e.
1971 -- is defined in some currently open scope (RM 8.3(4)).
1973 -- Is_Imported (Flag24)
1974 -- Present in all entities. Set if the entity is imported. For now we
1975 -- only allow the import of exceptions, functions, procedures, packages.
1976 -- and variables. Exceptions can only be imported in the OpenVMS and
1977 -- Java VM implementations of GNAT. Packages and types can only be
1978 -- imported in the Java VM implementation.

1981 -- Applies to all entities, true for private and incomplete types
1983 -- Is_Indefinite_Subtype (synthesized)
1984 -- Applies to all entities for types and subtypes. Determines if given

1986 -- record type or subtype with no initial discriminant values or a
1987 -- class wide type or subtype.
1989 -- Is_Inlined (Flag11)
1990 -- Present in all entities. Set for functions and procedures which are
1991 -- to be inlined. For subprograms created during expansion, this flag
1992 -- may be set directly by the expander to request inlining. Also set
1993 -- for packages that contain inlined subprograms, whose bodies must be
1994 -- be compiled. Is_Inlined is also set on generic subprograms and is
1995 -- inherited by their instances. It is also set on the body entities
1996 -- of inlined subprograms. See also Has_Pragma_Inline.
1998 -- Is_Instantiated (Flag126)
1999 -- Present in generic packages and generic subprograms. Set if the unit
2000 -- is instantiated from somewhere in the extended main source unit. This
2001 -- flag is used to control warnings about the unit being uninstantiated.

2003 -- formal in an instantiation. Also set on a parent instance, in the
2004 -- instantiation of a child, which is implicitly declared in the parent.
2006 -- Is_Integer_Type (synthesized)
2007 -- Applies to all entities, true for integer types and subtypes
2009 -- Is_Interface (Flag186)
2010 -- Present in record types and subtypes to indicate that the current
2011 -- entity corresponds with an abstract interface. Because abstract
2012 -- interfaces are conceptually a special kind of abstract tagged types
2013 -- we represent them by means of tagged record types and subtypes
2014 -- marked with this attribute. This allows us to reuse most of the
2015 -- compiler support for abstract tagged types to implement interfaces
2016 -- (Ada 2005: AI-251).
2018 -- Is_Internal (Flag17)
2019 -- Present in all entities. Set to indicate an entity created during
2020 -- semantic processing (e.g. an implicit type, or a temporary). The
2021 -- only current use of this flag is to indicate that temporaries
2022 -- generated for the result of an inlined function call need not be
2023 -- initialized, even when scalars are initialized or normalized.
2025 -- Is_Interrupt_Handler (Flag89)
2026 -- Present in procedures. Set if a pragma Interrupt_Handler applies
2027 -- to the procedure. The procedure must be parameterless, and on all
2028 -- targets except AAMP it must be a protected procedure.
2030 -- Is_Intrinsic_Subprogram (Flag64)
2031 -- Present in functions and procedures. It is set if a valid pragma
2032 -- Interface or Import is present for this subprogram specifying pragma
2033 -- Intrinsic. Valid means that the name and profile of the subprogram
2034 -- match the requirements of one of the recognized intrinsic subprograms
2035 -- (see package Sem_Intr for details). Note: the value of Convention for
2036 -- such an entity will be set to Convention_Intrinsic, but it is the
2037 -- setting of Is_Intrinsic_Subprogram, NOT simply having convention set
2038 -- to intrinsic, which causes intrinsic code to be generated.
2040 -- Is_Itype (Flag91)
2041 -- Present in all entities, set for Itypes. If it is set, then the
2042 -- declaration for the type does not appear explicitly in the tree.
2043 -- Instead gigi will elaborate the type when it is first used.
2044 -- Has_Delayed_Freeze can be set for Itypes, and the meaning is that
2045 -- the first use (the one which causes the type to be defined) will
2046 -- be the freeze node. Note that an important restriction on Itypes
2047 -- is that the first use of such a type (the one that causes it to be
2048 -- defined) must be in the same scope as the type.
2050 -- Is_Known_Non_Null (Flag37)
2051 -- Present in all entities. Relevant (and can be set True) only for
2052 -- objects of an access type. It is set if the object is currently
2053 -- known to have a non-null value (meaning that no access checks
2054 -- are needed). The indication can for example come from assignment
2055 -- of an access parameter or an allocator.
2057 -- Note: this flag is set according to the sequential flow of the
2058 -- program, watching the current value of the variable. However,
2059 -- this processing can miss cases of changing the value of an aliased
2060 -- or constant object, so even if this flag is set, it should not
2061 -- be believed if the variable is aliased or volatile. It would
2062 -- be a little neater to avoid the flag being set in the first
2063 -- place in such cases, but that's trickier, and there is only
2064 -- one place that tests the value anyway.
2066 -- The flag is dynamically set and reset as semantic analysis and
2067 -- expansion proceeds. Its value is meaningless once the tree is
2068 -- fully constructed, since it simply indicates the last state.
2069 -- Thus this flag has no meaning to the back end.
2071 -- Is_Known_Valid (Flag170)
2072 -- Present in all entities. Relevant for types (and subtype) and
2073 -- for objects (and enumeration literals) of a discrete type.
2075 -- The purpose of this flag is to implement the requirement stated
2076 -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
2077 -- values may not cause programs to become erroneous. See the function
2078 -- Exp_Util.Expr_Known_Valid for further details. Note that the setting
2079 -- is conservative, in the sense that if the flag is set, it must be
2080 -- right. If the flag is not set, nothing is known about the validity.
2082 -- For enumeration literals, the flag is always set, since clearly
2083 -- an enumeration literal represents a valid value. Range checks
2084 -- where necessary will ensure that this valid value is appropriate.
2086 -- For objects, the flag indicates the state of knowledge about the
2087 -- current value of the object. This may be modified during expansion,
2088 -- and thus the final value is not relevant to gigi.
2090 -- For types and subtypes, the flag is set if all possible bit patterns
2091 -- of length Object_Size (i.e. Esize of the type) represent valid values
2092 -- of the type. In general for such tytpes, all values are valid, the
2093 -- only exception being the case where an object of the type has an
2094 -- explicit size that is greater than Object_Size.
2096 -- For non-discrete objects, the setting of the Is_Known_Valid flag is
2097 -- not defined, and is not relevant, since the considerations of the
2098 -- requirement in (RM 13.9.1(9-11)) do not apply.
2100 -- The flag is dynamically set and reset as semantic analysis and
2101 -- expansion proceeds. Its value is meaningless once the tree is
2102 -- fully constructed, since it simply indicates the last state.
2103 -- Thus this flag has no meaning to the back end.
2105 -- Is_Limited_Composite (Flag106)
2106 -- Present in all entities. True for composite types that have a
2107 -- limited component. Used to enforce the rule that operations on
2108 -- the composite type that depend on the full view of the component
2109 -- do not become visible until the immediate scope of the composite
2110 -- type itself (RM 7.3.1 (5)).
2112 -- Is_Limited_Interface (Flag197)
2113 -- Present in types that are interfaces. True if interface is declared
2114 -- limited, or is derived from limited interfaces.
2116 -- Is_Limited_Record (Flag25)
2117 -- Present in all entities. Set to true for record (sub)types if the
2118 -- record is declared to be limited. Note that this flag is not set
2119 -- simply because some components of the record are limited.
2121 -- Is_Limited_Type (synthesized)
2122 -- Applies to all entities. True if entity is a limited type (limited
2123 -- private type, task type, protected type, composite containing a
2124 -- limited component, or a subtype of any of these types).
2126 -- Is_Machine_Code_Subprogram (Flag137)
2127 -- Present in subprogram entities. Set to indicate that the subprogram
2128 -- is a machine code subprogram (i.e. its body includes at least one
2129 -- code statement). Also indicates that all necessary semantic checks
2130 -- as required by RM 13.8(3) have been performed.
2132 -- Is_Modular_Integer_Type (synthesized)
2133 -- Applies to all entities. True if entity is a modular integer type
2135 -- Is_Non_Static_Subtype (Flag109)
2136 -- This flag is present in all type and subtype entities. It is set in
2137 -- some (but not all) cases in which a subtype is known to be non-static.
2138 -- Before this flag was added, the computation of whether a subtype was
2139 -- static was entirely synthesized, by looking at the bounds, and the
2140 -- immediate subtype parent. However, this method does not work for some
2141 -- Itypes that have no parent set (and the only way to find the immediate
2142 -- subtype parent is to go through the tree). For now, this flay is set
2143 -- conservatively, i.e. if it is set then for sure the subtype is non-
2144 -- static, but if it is not set, then the type may or may not be static.
2145 -- Thus the test for a static subtype is that this flag is clear AND
2146 -- that the bounds are static AND that the parent subtype (if available
2147 -- to be tested) is static. Eventually we should make sure this flag
2148 -- is always set right, at which point, these comments can be removed,
2149 -- and the tests for static subtypes greatly simplified.
2151 -- Is_Null_Init_Proc (Flag178)
2152 -- Present in procedure entities. Set for generated init proc procedures
2153 -- (used to initialize composite types), if the code for the procedure
2154 -- is null (i.e. is a return and nothing else). Such null initialization
2155 -- procedures are generated in case some client is compiled using the
2156 -- Initialize_Scalars pragma, generating a call to this null procedure,
2157 -- but there is no need to call such procedures within a compilation
2158 -- unit, and this flag is used to suppress such calls.
2160 -- Is_Numeric_Type (synthesized)
2161 -- Applies to all entities, true for all numeric types and subtypes
2162 -- (integer, fixed, float).
2164 -- Is_Object (synthesized)
2165 -- Applies to all entities, true for entities representing objects,
2166 -- including generic formal parameters.
2168 -- Is_Obsolescent (Flag153)
2169 -- Present in all entities. Set only for packages and subprograms to
2170 -- which a valid pragma Obsolescent applies.
2172 -- Is_Optional_Parameter (Flag134)
2173 -- Present in parameter entities. Set if the parameter is specified as
2174 -- optional by use of a First_Optional_Parameter argument to one of the
2175 -- extended Import pragmas. Can only be set for OpenVMS versions of GNAT.
2177 -- Is_Ordinary_Fixed_Point_Type (synthesized)
2178 -- Applies to all entities, true for ordinary fixed point types
2181 -- Is_Overriding_Operation (Flag39)
2182 -- Present in subprograms. Set if the subprogram is a primitive
2183 -- operation of a derived type, that overrides an inherited operation.
2185 -- Is_Package_Or_Generic_Package (synthesized)
2186 -- Applies to all entities. True for packages and generic packages.
2187 -- False for all other entities.
2189 -- Is_Package_Body_Entity (Flag160)
2190 -- Present in all entities. Set for entities defined at the top level
2191 -- of a package body. Used to control externally generated names.
2193 -- Is_Packed (Flag51) [implementation base type only]
2194 -- Present in all type entities. This flag is set only for record and
2195 -- array types which have a packed representation. There are three
2196 -- cases which cause packing:
2198 -- 1. Explicit use of pragma Pack for an array of package components
2199 -- 2. Explicit use of pragma Pack to pack a record
2200 -- 4. Setting Component_Size of an array to a bit-packable value
2201 -- 3. Indexing an array with a non-standard enumeration type.
2203 -- For records, Is_Packed is always set if Has_Pack_Pragma is set,
2204 -- and can also be set on its own in a derived type which inherited
2205 -- its packed status.
2207 -- For arrays, Is_Packed is set if an array is bit packed (i.e. the
2208 -- component size is known at compile time and is 1-7, 9-15 or 17-31),
2209 -- or if the array has one or more index types that are enumeration
2210 -- types with non-standard representations (in GNAT, we store such
2211 -- arrays compactly, using the Pos of the enumeration type value).
2213 -- As for the case of records, Is_Packed can be set on its own for a
2214 -- derived type, with the same dual before/after freeze meaning.
2215 -- Is_Packed can also be set as the result of an explicit component
2216 -- size clause that specifies an appropriate component size.
2218 -- In the bit packed array case, Is_Bit_Packed_Array will be set in
2219 -- the bit packed case once the array type is frozen.
2221 -- Before an array type is frozen, Is_Packed will always be set if
2222 -- Has_Pack_Pragma is set. Before the freeze point, it is not possible
2223 -- to know the component size, since the component type is not frozen
2224 -- until the array type is frozen. Thus Is_Packed for an array type
2225 -- before it is frozen means that packed is required. Then if it turns
2226 -- out that the component size is not suitable for bit packing, the
2227 -- Is_Packed flag gets turned off.
2229 -- Is_Packed_Array_Type (Flag138)
2230 -- Present in all entities. This flag is set on the entity for the type
2231 -- used to implement a packed array (either a modular type, or a subtype
2232 -- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
2233 -- if the type appears in the Packed_Array_Type field of some other type
2234 -- entity. It is used by Gigi to activate the special processing for such
2235 -- types (unchecked conversions that would not otherwise be allowed are
2236 -- allowed for such types). If the Is_Packed_Array_Type flag is set in
2237 -- an entity, then the Original_Array_Type field of this entity points
2238 -- to the original array type for which this is the packed array type.
2240 -- Is_Potentially_Use_Visible (Flag9)
2241 -- Present in all entities. Set if entity is potentially use visible,
2242 -- i.e. it is defined in a package that appears in a currently active
2243 -- use clause (RM 8.4(8)). Note that potentially use visible entities
2244 -- are not necessarily use visible (RM 8.4(9-11)).
2246 -- Is_Preelaborated (Flag59)
2247 -- Present in all entities, set in E_Package and E_Generic_Package
2248 -- entities to which a pragma Preelaborate is applied, and also in
2249 -- all entities within such packages. Note that the fact that this
2250 -- flag is set does not necesarily mean that no elaboration code is
2251 -- generated for the package.
2253 -- Is_Primitive_Wrapper (Flag195)
2254 -- Present in E_Procedures. Primitive wrappers are Expander-generated
2255 -- procedures that wrap entries of protected or task types implementing
2256 -- a limited interface.
2258 -- Is_Private_Composite (Flag107)
2259 -- Present in composite types that have a private component. Used to
2260 -- enforce the rule that operations on the composite type that depend
2261 -- on the full view of the component, do not become visible until the
2262 -- immediate scope of the composite type itself (7.3.1 (5)). Both this
2263 -- flag and Is_Limited_Composite are needed.
2265 -- Is_Private_Descendant (Flag53)
2266 -- Present in entities that can represent library units (packages,
2267 -- functions, procedures). Set if the library unit is itself a private
2268 -- child unit, or if it is the descendent of a private child unit.
2270 -- Is_Private_Type (synthesized)
2271 -- Applies to all entities, true for private types and subtypes,
2272 -- as well as for record with private types as subtypes
2274 -- Is_Protected_Interface (Flag198)
2275 -- Present in types that are interfaces. True if interface is declared
2276 -- protected, or is derived from protected interfaces.
2278 -- Is_Protected_Type (synthesized)
2279 -- Applies to all entities, true for protected types and subtypes
2281 -- Is_Public (Flag10)
2282 -- Present in all entities. Set to indicate that an entity defined in
2283 -- one compilation unit can be referenced from other compilation units.
2284 -- If this reference causes a reference in the generated variable, for
2285 -- example in the case of a variable name, then Gigi will generate an
2286 -- appropriate external name for use by the linker.
2288 -- Is_Protected_Private (synthesized)
2289 -- Applies to a record component. Returns true if this component
2290 -- is used to represent a private declaration of a protected type.
2292 -- Is_Protected_Record_Type (synthesized)
2293 -- Applies to all entities, true if Is_Concurrent_Record_Type
2294 -- Corresponding_Concurrent_Type is a protected type.
2297 -- Present in all entities. Set in all entities of a unit to which a
2298 -- pragma Pure is applied, and also set for the entity of the unit
2299 -- itself. In addition, this flag may be set for any other functions
2300 -- or procedures that are known to be side effect free, so in the case
2301 -- of subprograms, the Is_Pure flag may be used by the optimizer to
2302 -- imply that it can assume freedom from side effects (other than those
2303 -- resulting from assignment to out parameters, or to objects designated
2304 -- by access parameters).
2306 -- Is_Pure_Unit_Access_Type (Flag189)
2307 -- Present in access type and subtype entities. Set if the type or
2308 -- subtype appears in a pure unit. Used to give an error message at
2309 -- freeze time if the access type has a storage pool.
2311 -- Is_Real_Type (synthesized)
2312 -- Applies to all entities, true for real types and subtypes
2314 -- Is_Record_Type (synthesized)
2315 -- Applies to all entities, true for record types and subtypes,
2316 -- includes class-wide types and subtypes (which are also records)
2318 -- Is_Remote_Call_Interface (Flag62)
2319 -- Present in all entities, set in E_Package and E_Generic_Package
2320 -- entities to which a pragma Remote_Call_Interace is applied, and
2321 -- also in all entities within such packages.
2323 -- Is_Remote_Types (Flag61)
2324 -- Present in all entities, set in E_Package and E_Generic_Package
2325 -- entities to which a pragma Remote_Types is applied, and also in
2326 -- all entities within such packages.
2328 -- Is_Renaming_Of_Object (Flag112)
2329 -- Present in all entities, set only for a variable or constant for
2330 -- which the Renamed_Object field is non-empty and for which the
2331 -- renaming is handled by the front end, by macro substitution of
2332 -- a copy of the (evaluated) name tree whereever the variable is used.
2334 -- Is_Return_By_Reference_Type (synthesized)
2335 -- Applies to all type entities. True if the type is required to
2336 -- be returned by reference, as defined in 6.5(11-16).
2338 -- Is_Scalar_Type (synthesized)
2339 -- Applies to all entities, true for scalar types and subtypes
2341 -- Is_Shared_Passive (Flag60)
2342 -- Present in all entities, set in E_Package and E_Generic_Package
2343 -- entities to which a pragma Shared_Passive is applied, and also in
2344 -- all entities within such packages.
2346 -- Is_Statically_Allocated (Flag28)
2347 -- Present in all entities. This can only be set True for exception,
2348 -- variable, constant, and type/subtype entities. If the flag is set,
2349 -- then the variable or constant must be allocated statically rather
2350 -- than on the local stack frame. For exceptions, the meaning is that
2351 -- the exception data should be allocated statically (and indeed this
2352 -- flag is always set for exceptions, since exceptions do not have
2353 -- local scope). For a type, the meaning is that the type must be
2354 -- elaborated at the global level rather than locally. No type marked
2355 -- with this flag may depend on a local variable, or on any other type
2356 -- which does not also have this flag set to True. For a variable or
2357 -- or constant, if the flag is set, then the type of the object must
2358 -- either be declared at the library level, or it must also have the
2359 -- flag set (since to allocate the oject statically, its type must
2360 -- also be elaborated globally).
2362 -- Is_Subprogram (synthesized)
2363 -- Applies to all entities, true for bodies of functions, procedures
2366 -- Is_String_Type (synthesized)
2367 -- Applies to all type entities. Determines if the given type is a
2368 -- string type, i.e. it is directly a string type or string subtype,
2369 -- or a string slice type, or an array type with one dimension and a
2370 -- component type that is a character type.
2372 -- Is_Synchronized_Interface (Flag199)
2373 -- Present_types that are interfaces. True is interface is declared
2374 -- synchronized, or is derived from synchronized interfaces.
2377 -- Present in E_Component. For regular tagged type this flag is set on
2378 -- the tag component (whose name is Name_uTag) and for CPP_Class tagged
2379 -- types, this flag marks the pointer to the main vtable (i.e. the one
2380 -- to be extended by derivation)
2382 -- Is_Tagged_Type (Flag55)
2383 -- Present in all entities, true for an entity for a tagged type.
2385 -- Is_Task_Interface (Flag200)
2386 -- Present in types that are interfaces. True is interface is declared
2387 -- as such, or if it is derived from task interfaces.
2389 -- Is_Task_Record_Type (synthesized)
2390 -- Applies to all entities, true if Is_Concurrent_Record_Type
2391 -- Corresponding_Concurrent_Type is a task type.
2393 -- Is_Task_Type (synthesized)
2394 -- Applies to all entities, true for task types and subtypes
2396 -- Is_Thread_Body (Flag77)
2397 -- Applies to subprogram entities. Set if a valid Thread_Body pragma
2398 -- applies to this subprogram, which is thus a thread body.
2400 -- Is_True_Constant (Flag163)
2401 -- This flag is set in constants and variables which have an initial
2402 -- value specified but which are never assigned, partially or in the
2403 -- whole. For variables, it means that the variable was initialized
2404 -- but never modified, and hence can be treated as a constant by the
2405 -- code generator. For a constant, it means that the constant was not
2406 -- modified by generated code (e.g. to set a discriminant in an init
2407 -- proc). Assignments by user or generated code will reset this flag.
2409 -- Note: there is one situation in which the back end does not permit
2410 -- this flag to be set, even if no assignments are generated. This is
2411 -- the case of an object of a record or array type which is initialized
2412 -- with an aggregate, and is itself used as the expression initializing
2413 -- an atomic object, or the right hand side of an assignment to an atomic
2414 -- object. In this case the object must not have Is_True_Constant set,
2415 -- even though no assignments are generated (the reason for this is that
2416 -- the back end must not optimize the object away, because that would
2417 -- violate the restriction on aggregates in these positions).
2419 -- Is_Type (synthesized)
2420 -- Applies to all entities, true for a type entity
2422 -- Is_Unchecked_Union (Flag117)
2423 -- Present in all entities. Set only in record types to which the
2424 -- pragma Unchecked_Union has been validly applied.
2426 -- Is_Unsigned_Type (Flag144)
2427 -- Present in all types, but can be set only for discrete and fixed-point
2428 -- type and subtype entities. This flag is only valid if the entity is
2429 -- frozen. If set it indicates that the representation is known to be
2430 -- unsigned (i.e. that no negative values appear in the range). This is
2431 -- normally just a reflection of the lower bound of the subtype or base
2432 -- type, but there is one case in which the setting is non-obvious,
2433 -- namely the case of an unsigned subtype of a signed type from which
2434 -- a further subtype is obtained using variable bounds. This further
2435 -- subtype is still unsigned, but this cannot be determined by looking
2436 -- at its bounds or the bounds of the corresponding base type.
2438 -- Is_Valued_Procedure (Flag127)
2439 -- Present in procedure entities. Set if an Import_Valued_Procedure
2440 -- or Export_Valued_Procedure pragma applies to the procedure entity.
2442 -- Is_Visible_Child_Unit (Flag116)
2443 -- Present in compilation units that are child units. Once compiled,
2444 -- child units remain chained to the entities in the parent unit, and
2445 -- a separate flag must be used to indicate whether the names are
2446 -- visible by selected notation, or not.
2448 -- Is_VMS_Exception (Flag133)
2449 -- Present in all entities. Set only for exception entities where the
2450 -- exception was specified in an Import_Exception or Export_Exception
2451 -- pragma with the VMS option for Form. See description of these pragmas
2452 -- for details. This flag can only be set in OpenVMS versions of GNAT.
2454 -- Is_Volatile (Flag16)
2455 -- Present in all type entities, and also in constants, components and
2456 -- variables. Set if a pragma Volatile applies to the entity. Also set
2457 -- if pragma Shared or pragma Atomic applies to entity. In the case of
2458 -- private or incomplete types, this flag is set in both the private
2459 -- and full view. The flag is not set reliably on private subtypes,
2460 -- and is always retrieved from the base type (but this is not a base-
2461 -- type-only attribute because it applies to other entities). Note that
2462 -- the back end should use Treat_As_Volatile, rather than Is_Volatile
2463 -- to indicate code generation requirements for volatile variables.
2464 -- Similarly, any front end test which is concerned with suppressing
2465 -- optimizations on volatile objects should test Treat_As_Volatile
2466 -- rather than testing this flag.
2468 -- Is_Wrapper_Package (synthesized)
2469 -- Present in package entities. Indicates that the package has been
2470 -- created as a wrapper for a subprogram instantiation.
2472 -- Itype_Printed (Flag202)
2473 -- Set in Itypes if the Itype has been printed by Sprint. This is used to
2474 -- avoid printing an Itype more than once.
2476 -- Kill_Elaboration_Checks (Flag32)
2477 -- Present in all entities. Set by the expander to kill elaboration
2478 -- checks which are known not to be needed. Equivalent in effect to
2479 -- the use of pragma Supress (Elaboration_Checks) for that entity
2480 -- except that the effect is permanent and cannot be undone by a
2481 -- subsequent pragma Unsuppress.
2483 -- Kill_Range_Checks (Flag33)
2484 -- Present in all entities. Set by the expander to kill elaboration
2485 -- checks which are known not to be needed. Equivalent in effect to
2486 -- the use of pragma Supress (Range_Checks) for that entity except
2487 -- that the result is permanent and cannot be undone by a subsequent
2488 -- pragma Unsuppress.
2490 -- Kill_Tag_Checks (Flag34)
2491 -- Present in all entities. Set by the expander to kill elaboration
2492 -- checks which are known not to be needed. Equivalent in effect to
2493 -- the use of pragma Supress (Tag_Checks) for that entity except
2494 -- that the result is permanent and cannot be undone by a subsequent
2495 -- pragma Unsuppress.
2497 -- Last_Entity (Node20)
2498 -- Present in all entities which act as scopes to which a list of
2499 -- associated entities is attached (blocks, class subtypes and types,
2500 -- entries, functions, loops, packages, procedures, protected objects,
2501 -- record types and subtypes, private types, task types and subtypes).
2502 -- Points to a the last entry in the list of associated entities chained
2503 -- through the Next_Entity field. Empty if no entities are chained.
2505 -- Limited_View (Node23)
2506 -- Present in non-generic package entities that are not instances. Bona
2507 -- fide package with the limited-view list through the first_entity and
2508 -- first_private attributes. The elements of this list are the shadow
2509 -- entities created for the types and local packages that are declared
2510 -- in a package appearing in a limited_with clause (Ada 2005: AI-50217)
2512 -- Lit_Indexes (Node15)
2513 -- Present in enumeration types and subtypes. Non-empty only for the
2514 -- case of an enumeration root type, where it contains the entity for
2515 -- the generated indexes entity. See unit Exp_Imgv for full details of
2516 -- the nature and use of this entity for implkementing the Image and
2517 -- Value attributes for the enumeration type in question.
2519 -- Lit_Strings (Node16)
2520 -- Present in enumeration types and subtypes. Non-empty only for the
2521 -- case of an enumeration root type, where it contains the entity for
2522 -- the literals string entity. See unit Exp_Imgv for full details of
2523 -- the nature and use of this entity for implementing the Image and
2524 -- Value attributes for the enumeration type in question.
2526 -- Machine_Radix_10 (Flag84)
2527 -- Present in decimal types and subtypes, set if the Machine_Radix
2528 -- is 10, as the result of the specification of a machine radix
2529 -- representation clause. Note that it is possible for this flag
2530 -- to be set without having Has_Machine_Radix_Clause True. This
2531 -- happens when a type is derived from a type with a clause present.
2533 -- Master_Id (Node17)
2534 -- Present in access types and subtypes. Empty unless Has_Task is
2535 -- set for the designated type, in which case it points to the entity
2536 -- for the Master_Id for the access type master.
2538 -- Materialize_Entity (Flag168)
2539 -- Present in all entities. Set only for constant or renamed entities
2540 -- which should be materialized for debugging purposes. In the case of
2541 -- a constant, a memory location should be allocated containing the
2542 -- value. In the case of a renaming, a memory location containing the
2543 -- renamed address should be allocated.
2545 -- Mechanism (Uint8) (returned as Mechanism_Type)
2546 -- Present in functions and non-generic formal parameters. Indicates
2547 -- the mechanism to be used for the function return or for the formal
2548 -- parameter. See separate section on passing mechanisms. This field
2549 -- is also set (to the default value of zero) in a subprogram body
2550 -- entity but not used in this context.
2552 -- Modulus (Uint17) [base type only]
2553 -- Present in modular types. Contains the modulus. For the binary
2554 -- case, this will be a power of 2, but if Non_Binary_Modulus is
2555 -- set, then it will not be a power of 2.
2557 -- Must_Be_On_Byte_Boundary (Flag183)
2558 -- Present in entities for types and subtypes. Set if objects of
2559 -- the type must always be allocated on a byte boundary (more
2560 -- accurately a storage unit boundary). The front end checks that
2561 -- component clauses respect this rule, and the back end ensures
2562 -- that record packing does not violate this rule. Currently the
2563 -- flag is set only for packed arrays longer than 64 bits where
2564 -- the component size is not a power of 2.
2566 -- Needs_Debug_Info (Flag147)
2567 -- Present in all entities. Set if the entity requires debugging
2568 -- information to be generated. This is true of all entities that
2569 -- have Comes_From_Source set, and also transitively for entities
2570 -- associated with such components (e.g. their types). It is true
2571 -- for all entities in Debug_Generated_Code mode (-gnatD switch).
2572 -- This is the flag that the back end should check to determine
2573 -- whether or not to generate debugging information for an entity.
2575 -- Needs_No_Actuals (Flag22)
2576 -- Present in callable entities (subprograms, entries, access to
2577 -- subprograms) which can be called without actuals because all of
2578 -- their formals (if any) have default values. This flag simplifies the
2579 -- resolution of the syntactic ambiguity involving a call to these
2580 -- entities when the return type is an array type, and a call can be
2581 -- interpreted as an indexing of the result of the call. It is also
2582 -- used to resolve various cases of entry calls.
2584 -- Never_Set_In_Source (Flag115)
2585 -- Present in all entities, but relevant only for variables and
2586 -- parameters. This flag is set if the object is never assigned
2587 -- a value in user source code, either by assignment or by the
2588 -- use of an initial value, or by some other means.
2590 -- This flag is only for the purposes of issuing warnings, it must not
2591 -- be used by the code generator to indicate that the variable is in
2592 -- fact a constant, since some assignments in generated code do not
2593 -- count (for example, the call to an init proc to assign some but
2594 -- not all of the fields in a partially initialized record). The code
2595 -- generator should instead use the flag Is_True_Constant.
2597 -- For the purposes of this warning, the default assignment of
2598 -- access variables to null is not considered the assignment of
2599 -- of a value (so the warning can be given for code that relies
2600 -- on this initial null value, when no other value is ever set).
2602 -- In variables and out parameters, if this flag is set after full
2603 -- processing of the corresponding declarative unit, it indicates that
2604 -- the variable or parameter was never set, and a warning message can
2607 -- Note: this flag is initially set, and then cleared on encountering
2608 -- any construct that might conceivably legitimately set the value.
2609 -- Thus during the analysis of a declarative region and its associated
2610 -- statement sequence, the meaning of the flag is "not set yet", and
2611 -- once this analysis is complete the flag means "never assigned".
2613 -- Note: for variables appearing in package declarations, this flag
2614 -- is never set. That is because there is no way to tell if some
2615 -- client modifies the variable (or in the case of variables in the
2616 -- private part, if some child unit modifies the variables).
2618 -- Note: in the case of renamed objects, the flag must be set in the
2619 -- ultimate renamed object. Clients noting a possible modification
2620 -- should use the Note_Possible_Modification procedure in Sem_Util
2621 -- rather than Set_Never_Set_In_Source precisely to deal properly with
2622 -- the renaming possibility.
2624 -- Next_Component (synthesized)
2625 -- Applies to record components. Returns the next component by
2626 -- following the chain of declared entities until one is found which
2627 -- corresponds to a component (Ekind is E_Component). Any internal types
2628 -- generated from the subtype indications of the record components are
2629 -- skipped. Returns Empty if no more components.
2631 -- Next_Discriminant (synthesized)
2632 -- Applies to discriminants returned by First/Next_Discriminant.
2633 -- Returns the next language-defined (ie: perhaps non-girder)
2634 -- discriminant by following the chain of declared entities as long as
2635 -- the kind of the entity corresponds to a discriminant. Note that the
2636 -- discriminants might be the only components of the record.
2637 -- Returns Empty if there are no more.
2639 -- Next_Entity (Node2)
2640 -- Present in all entities. The entities of a scope are chained, with
2641 -- the head of the list being in the First_Entity field of the scope
2642 -- entity. All entities use the Next_Entity field as a forward pointer
2643 -- for this list, with Empty indicating the end of the list. Since this
2644 -- field is in the base part of the entity, the access routines for this
2645 -- field are in Sinfo.
2647 -- Next_Formal (synthesized)
2648 -- Applies to the entity for a formal parameter. Returns the next
2649 -- formal parameter of the subprogram or subprogram type. Returns
2650 -- Empty if there are no more formals.
2652 -- Next_Formal_With_Extras (synthesized)
2653 -- Applies to the entity for a formal parameter. Returns the next
2654 -- formal parameter of the subprogram or subprogram type. Returns
2655 -- Empty if there are no more formals. The list returned includes
2656 -- all the extra formals (see description of Extra_Formal field)
2658 -- Next_Girder_Discriminant (synthesized)
2659 -- Applies to discriminants. Set only for a discriminant returned by
2660 -- a call to First/Next_Girder_Discriminant. Returns next girder
2661 -- discriminant, if there are more (see complete description in
2662 -- First_Girder_Discriminant), or Empty if there are no more.
2664 -- Next_Index (synthesized)
2665 -- Applies to array types and subtypes and to string types and
2666 -- subtypes. Yields the next index. The first index is obtained by
2667 -- using the First_Index attribute, and then subsequent indexes are
2668 -- obtained by applying Next_Index to the previous index. Empty is
2669 -- returned to indicate that there are no more indexes. Note that
2670 -- unlike most attributes in this package, Next_Index applies to
2671 -- nodes for the indexes, not to entities.
2673 -- Next_Inlined_Subprogram (Node12)
2674 -- Present in subprograms. Used to chain inlined subprograms used in
2675 -- the current compilation, in the order in which they must be compiled
2676 -- by Gigi to insure that all inlinings are performed.
2678 -- Next_Literal (synthesized)
2679 -- Applies to enumeration literals, returns the next literal, or
2680 -- Empty if applied to the last literal. This is actually a synonym
2681 -- for Next, but its use is preferred in this context.
2683 -- Non_Binary_Modulus (Flag58) [base type only]
2684 -- Present in modular integer types. Set if the modulus for the type
2685 -- is other than a power of 2.
2687 -- Non_Limited_View (Node17)
2688 -- Present in incomplete types that are the shadow entities created
2689 -- when analyzing a limited_with_clause (Ada 2005: AI-50217). Points to
2690 -- the defining entity in the original declaration.
2692 -- Nonzero_Is_True (Flag162) [base type only]
2693 -- Present in enumeration types. True if any non-zero value is to be
2694 -- interpreted as true. Currently this is set true for derived Boolean
2695 -- types which have a convention of C, C++ or Fortran.
2697 -- No_Pool_Assigned (Flag131) [root type only]
2698 -- Present in access types. Set if a storage size clause applies to
2699 -- the variable with a compile time known value of zero. This flag is
2700 -- used to generate warnings if any attempt is made to allocate or free
2701 -- an instance of such an access type. This is set only in the root
2702 -- type, since derived types must have the same pool.
2704 -- No_Return (Flag113)
2705 -- Present in procedure and generic procedure entries. Indicates that
2706 -- a pragma No_Return applies to the procedure.
2708 -- Normalized_First_Bit (Uint8)
2709 -- Present in components and discriminants. Indicates the normalized
2710 -- value of First_Bit for the component, i.e. the offset within the
2711 -- lowest addressed storage unit containing part or all of the field.
2712 -- Set to No_Uint if no first bit position is assigned yet.
2714 -- Normalized_Position (Uint14)
2715 -- Present in components and discriminants. Indicates the normalized
2716 -- value of Position for the component, i.e. the offset in storage
2717 -- units from the start of the record to the lowest addressed storage
2718 -- unit containing part or all of the field.
2720 -- Normalized_Position_Max (Uint10)
2721 -- Present in components and discriminants. For almost all cases, this
2722 -- is the same as Normalized_Position. The one exception is for the case
2723 -- of a discriminated record containing one or more arrays whose length
2724 -- depends on discriminants. In this case, the Normalized_Position_Max
2725 -- field represents the maximum possible value of Normalized_Position
2726 -- assuming min/max values for discriminant subscripts in all fields.
2727 -- This is used by Layout in front end layout mode to properly computed
2728 -- the maximum size such records (needed for allocation purposes when
2729 -- there are default discriminants, and also for the 'Size value).
2731 -- No_Strict_Aliasing (Flag136) [base type only]
2732 -- Present in access types. Set to direct the back end to avoid any
2733 -- optimizations based on an assumption about the aliasing status of
2734 -- objects designated by the access type. For the case of the gcc
2735 -- back end, the effect is as though all references to objects of
2736 -- the type were compiled with -fno-strict-aliasing. This flag is
2737 -- set if an unchecked conversion with the access type as a target
2738 -- type occurs in the same source unit as the declaration of the
2739 -- access type, or if an explicit pragma No_Strict_Aliasing applies.
2741 -- Number_Dimensions (synthesized)
2742 -- Applies to array types and subtypes. Returns the number of dimensions
2743 -- of the array type or subtype as a value of type Pos.
2745 -- Number_Discriminants (synthesized)
2746 -- Applies to all types with discriminants. Yields the number of
2747 -- discriminants as a value of type Pos.
2749 -- Number_Entries (synthesized)
2750 -- Applies to concurrent types. Returns the number of entries that are
2751 -- declared within the task or protected definition for the type.
2753 -- Number_Formals (synthesized)
2754 -- Applies to subprograms and subprogram types. Yields the number of
2755 -- formals as a value of type Pos.
2757 -- Obsolescent_Warning (Node24)
2758 -- Present in package and subprogram entities. Set non-empty only if the
2759 -- pragma Obsolescent had a string argument, in which case it records the
2760 -- contents of the corresponding string literal node.
2762 -- Original_Access_Type (Node21)
2763 -- Present in access to subprogram types. Anonymous access to protected
2764 -- subprogram types are replaced by an occurrence of an internal access
2765 -- to subprogram type. This field links the replacement entity with the
2768 -- Original_Array_Type (Node21)
2769 -- Present in modular types and array types and subtypes. Set only
2770 -- if the Is_Packed_Array_Type flag is set, indicating that the type
2771 -- is the implementation type for a packed array, and in this case it
2772 -- points to the original array type for which this is the packed
2773 -- array implementation type.
2775 -- Object_Ref (Node17)
2776 -- Present in protected bodies. This is an implicit prival for the
2777 -- Protection object associated with a protected object. See Prival
2778 -- for further details on the use of privals.
2780 -- Original_Record_Component (Node22)
2781 -- Present in components, including discriminants. The usage depends
2782 -- on whether the record is a base type and whether it is tagged.
2784 -- In base tagged types:
2785 -- When the component is inherited in a record extension, it points
2786 -- to the original component (the entity of the ancestor component
2787 -- which is not itself inherited) otherwise it points to itself.
2788 -- Gigi uses this attribute to implement the automatic dereference in
2789 -- the extension and to apply the transformation:
2791 -- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
2793 -- In base non-tagged types:
2794 -- Always points to itself except for non-girder discriminants, where
2795 -- it points to the girder discriminant it renames.
2797 -- In subtypes (tagged and untagged):
2798 -- Points to the component in the base type.
2800 -- Overridden_Operation (Node26)
2801 -- Present in subprograms. For overriding operations, points to the
2802 -- user-defined parent subprogram that is being overridden.
2804 -- Package_Instantiation (Node26)
2805 -- Present in packages and generic packages. When present, this field
2806 -- references an N_Package_Instantiation node associated with an
2807 -- instantiated package. In the case where the referenced node has
2808 -- been rewritten to an N_Package_Specification, the instantiation
2809 -- node is available from the Original_Node field of the package spec
2810 -- node. This is currently not guaranteed to be set in all cases, but
2811 -- when set, the field is used in Get_Package_Instantiation_Node as
2812 -- one of the means of obtaining the instantiation node. Eventually
2813 -- it should be set in all cases, including package entities associated
2814 -- with formal packages. ???
2816 -- Packed_Array_Type (Node23)
2817 -- Present in array types and subtypes, including the string literal
2818 -- subtype case, if the corresponding type is packed (either bit packed
2819 -- or packed to eliminate holes in non-contiguous enumeration type
2820 -- index types). References the type used to represent the packed array,
2821 -- which is either a modular type for short static arrays, or an
2822 -- array of System.Unsigned. Note that in some situations (internal
2823 -- types, and references to fields of variant records), it is not
2824 -- always possible to construct this type in advance of its use. If
2825 -- Packed_Array_Type is empty, then the necessary type is declared
2826 -- on the fly for each reference to the array.
2828 -- Parameter_Mode (synthesized)
2829 -- Applies to formal parameter entities. This is a synonym for Ekind,
2830 -- used when obtaining the formal kind of a formal parameter (the result
2831 -- is one of E_[In/Out/In_Out]_Paramter)
2833 -- Parent_Subtype (Node19)
2834 -- Present in E_Record_Type. Points to the subtype to use for a
2835 -- field that references the parent record.
2837 -- Primitive_Operations (Elist15)
2838 -- Present in tagged record types and subtypes and in tagged private
2839 -- types. Points to an element list of entities for primitive operations
2840 -- for the tagged type. Not present (and not set) in untagged types (it
2841 -- is an error to reference the primitive operations field of a type
2842 -- that is not tagged).
2844 -- Private_Dependents (Elist18)
2845 -- Present in private (sub)types. Records the subtypes of the
2846 -- private type, derivations from it, and records and arrays
2847 -- with components dependent on the type.
2849 -- The subtypes are traversed when installing and deinstalling
2850 -- (the full view of) a private type in order to ensure correct
2851 -- view of the subtypes.
2853 -- Used in similar fashion for incomplete types: holds list of subtypes
2854 -- of these incomplete types that have discriminant constraints. The
2855 -- full views of these subtypes are constructed when the full view of
2856 -- the incomplete type is processed.
2858 -- In addition, if the incomplete type is the designated type in an
2859 -- access definition for an access parameter, the operation may be
2860 -- a dispatching primitive operation, which is only known when the full
2861 -- declaration of the type is seen. Subprograms that have such an
2862 -- access parameter are also placed in the list of private_dependents.
2865 -- Present in components. Used for representing private declarations
2866 -- of protected objects (private formal: by analogy to Discriminal_Link).
2867 -- Empty unless the synthesized Is_Protected_Private attribute is
2868 -- true. The entity used as a formal parameter that corresponds to
2869 -- the to the private declaration in protected operations. See
2870 -- "Private data in protected objects" for details.
2872 -- Privals_Chain (Elist23)
2873 -- Present in protected operations (subprograms and entries). Links
2874 -- all occurrences of the Privals in the body of the operation, in
2875 -- order to patch their types at the end of their expansion. See
2876 -- "Private data in protected objects" for details.
2878 -- Private_View (Node22)
2879 -- For each private type, three entities are allocated, the private view,
2880 -- the full view, and the shadow entity. The shadow entity contains a
2881 -- copy of the private view and is used for restoring the proper private
2882 -- view after a region in which the full view is visible (and is copied
2883 -- into the entity normally used for the private view during this period
2884 -- of visibility). The Private_View field is self-referential when the
2885 -- private view lives in its normal entity, but in the copy that is made
2886 -- in the shadow entity, it points to the proper location in which to
2887 -- restore the private view saved in the shadow.
2889 -- Protected_Formal (Node22)
2890 -- Present in formal parameters (in, in out and out parameters). Used
2891 -- only for formals of protected operations. References corresponding
2892 -- formal parameter in the unprotected version of the operation that
2893 -- is created during expansion.
2895 -- Protected_Body_Subprogram (Node11)
2896 -- Present in protected operations. References the entity for the
2897 -- subprogram which implements the body of the operation.
2899 -- Protected_Operation (Node23)
2900 -- Present in components. Used for representing private declarations
2901 -- of protected objects. Empty unless the synthesized attribute
2902 -- Is_Protected_Private is True. This is the entity corresponding
2903 -- to the body of the protected operation currently being analyzed,
2904 -- and which will eventually use the current Prival associated with
2905 -- this component to refer to the renaming of a private object
2906 -- component. As soon as the expander generates this renaming, this
2907 -- attribute is changed to refer to the next protected subprogram.
2908 -- See "Private data in protected objects" for details.
2910 -- Reachable (Flag49)
2911 -- Present in labels. The flag is set over the range of statements in
2912 -- which a goto to that label is legal.
2914 -- Referenced (Flag156)
2915 -- Present in all entities, set if the entity is referenced, except
2916 -- for the case of an appearence of a simple variable that is not a
2917 -- renaming, as the left side of an assignment in which case the flag
2918 -- Referenced_As_LHS is set instead.
2920 -- Referenced_As_LHS (Flag36): This flag is set instead of
2921 -- Referenced if a simple variable that is not a renaming appears as
2922 -- the left side of an assignment. The reason we distinguish this kind
2923 -- of reference is that we have a separate warning for variables that
2924 -- are only assigned and never read.
2926 -- Referenced_Object (Node10)
2927 -- Present in all type entities. Set non-Empty only for type entities
2928 -- constructed for unconstrained objects, or objects that depend on
2929 -- discriminants. Points to the expression from which the actual
2930 -- subtype of the object can be evaluated.
2932 -- Register_Exception_Call (Node20)
2933 -- Present in exception entities. When an exception is declared,
2934 -- a call is expanded to Register_Exception. This field points to
2935 -- the expanded N_Procedure_Call_Statement node for this call. It
2936 -- is used for Import/Export_Exception processing to modify the
2937 -- register call to make appropriate entries in the special tables
2938 -- used for handling these pragmas at runtime.
2940 -- Related_Array_Object (Node19)
2941 -- Present in array types and subtypes. Used only for the base type
2942 -- and subtype created for an anonymous array object. Set to point
2943 -- to the entity of the corresponding array object. Currently used
2944 -- only for type-related error messages.
2946 -- Related_Instance (Node15)
2947 -- Present in the wrapper packages created for subprogram instances.
2948 -- The internal subprogram that implements the instance is inside the
2949 -- wrapper package, but for debugging purposes its external symbol
2950 -- must correspond to the name and scope of the related instance.
2952 -- Renamed_Entity (Node18)
2953 -- Present in exceptions, packages and generic units that are defined
2954 -- by a renaming declaration. Denotes the renamed entity, or transit-
2955 -- itively the ultimate renamed entity if there is a chain of renaming
2958 -- Renamed_Object (Node18)
2959 -- Present in all objects (constants, variables, components, formal
2960 -- parameters, generic formal parameters, and loop parameters). Set
2961 -- non-Empty if the object was declared by a renaming declaration, in
2962 -- which case it references the tree node for the name of the renamed
2963 -- object. This is only possible for the variable and constant cases.
2964 -- For formal parameters, this field is used in the course of inline
2965 -- expansion, to map the formals of a subprogram into the corresponding
2966 -- actuals. For formals of a task entry, it denotes the local renaming
2967 -- that replaces the actual within the accept statement.
2968 -- The field is Empty otherwise.
2970 -- Renaming_Map (Uint9)
2971 -- Present in generic subprograms, generic packages, and their
2972 -- instances. Also present in the instances of the corresponding
2973 -- bodies. Denotes the renaming map (generic entities => instance
2974 -- entities) used to construct the instance by givin an index into
2975 -- the tables used to represent these maps. See Sem_Ch12 for further
2976 -- details. The maps for package instances are also used when the
2977 -- instance is the actual corresponding to a formal package.
2979 -- Return_Present (Flag54)
2980 -- Present in function and generic function entities. Set if the
2981 -- function contains a return statement (used for error checking).
2982 -- This flag can also be set in procedure and generic procedure
2983 -- entities (for convenience in setting it), but is only tested
2984 -- for the function case.
2986 -- Returns_By_Ref (Flag90)
2987 -- Present in function entities, to indicate that the function
2988 -- returns the result by reference, either because its return typ is a
2989 -- by-reference-type or because it uses explicitly the secondary stack.
2991 -- Reverse_Bit_Order (Flag164) [base type only]
2992 -- Present in all record type entities. Set if a valid pragma an
2993 -- attribute represention clause for Bit_Order has reversed the order
2994 -- of bits from the default value. When this flag is set, a component
2995 -- clause must specify a set of bits entirely contained in a single
2999 -- Present in all type and subtype entities. Contains the value of
3000 -- type'Size as defined in the RM. See also the Esize field and
3001 -- and the description on "Handling of Type'Size Values". A value
3002 -- of zero in this field for a non-discrete type means that
3003 -- the front end has not yet determined the size value. For the
3004 -- case of a discrete type, this field is always set by the front
3005 -- end and zero is a legitimate value for a type with one value.
3007 -- Root_Type (synthesized)
3008 -- Applies to all type entities. For class-wide types, return the root
3009 -- type of the class covered by the CW type, otherwise returns the
3010 -- ultimate derivation ancestor of the given type. This function
3011 -- preserves the view, i.e. the Root_Type of a partial view is the
3012 -- partial view of the ulimate ancestor, the Root_Type of a full view
3013 -- is the full view of the ultimate ancestor. Note that this function
3014 -- does not correspond exactly to the use of root type in the RM, since
3015 -- in the RM root type applies to a class of types, not to a type.
3017 -- Scalar_Range (Node20)
3018 -- Present in all scalar types (including modular types, where the
3019 -- bounds are 0 .. modulus - 1). References a node in the tree that
3020 -- contains the bounds for the range. Note that this information
3021 -- could be obtained by rummaging around the tree, but it is more
3022 -- convenient to have it immediately at hand in the entity. The
3023 -- contents of Scalar_Range can either be an N_Subtype_Indication
3024 -- node (with a constraint), or a Range node, but not a simple
3025 -- subtype reference (a subtype is converted into a range).
3027 -- Scale_Value (Uint15)
3028 -- Present in decimal fixed-point types and subtypes. Contains the scale
3029 -- for the type (i.e. the value of type'Scale = the number of decimal
3030 -- digits after the decimal point).
3033 -- Present in all entities. Points to the entity for the scope (block,
3034 -- loop, subprogram, package etc.) in which the entity is declared.
3035 -- Since this field is in the base part of the entity node, the access
3036 -- routines for this field are in Sinfo.
3038 -- Scope_Depth (synth)
3039 -- Applies to program units, blocks, concurrent types and entries,
3040 -- and also to record types, i.e. to any entity that can appear on
3041 -- the scope stack. Yields the scope depth value, which for those
3042 -- entities other than records is simply the scope depth value,
3043 -- for record entities, it is the Scope_Depth of the record scope.
3045 -- Scope_Depth_Value (Uint22)
3046 -- Present in program units, blocks, concurrent types and entries.
3047 -- Indicates the number of scopes that statically enclose the
3048 -- declaration of the unit or type. Library units have a depth of zero.
3049 -- Note that record types can act as scopes but do NOT have this field
3050 -- set (see Scope_Depth above)
3052 -- Scope_Depth_Set (synthesized)
3053 -- Applies to a special predicate function that returns a Boolean value
3054 -- indicating whether or not the Scope_Depth field has been set. It
3055 -- is needed, since returns an invalid value in this case!
3057 -- Sec_Stack_Needed_For_Return (Flag167)
3058 -- Present in scope entities (blocks, functions, procedures, tasks,
3059 -- entries). Set to True when secondary stack is used to hold
3060 -- the returned value of a function and thus should not be
3061 -- released on scope exit.
3063 -- Shadow_Entities (List14)
3064 -- Present in package and generic package entities. Points to a list
3065 -- of entities that correspond to private types. For each private type
3066 -- a shadow entity is created that holds a copy of the private view.
3067 -- In regions of the program where the full views of these private
3068 -- entities are visible, the full view is copied into the entity that
3069 -- is normally used to hold the private view, but the shadow entity
3070 -- copy is unchanged. The shadow entities are then used to restore the
3071 -- original private views at the end of the region. This list is a
3072 -- standard format list (i.e. First (Shadow_Entities) is the first
3073 -- entry and subsequent entries are obtained using Next.
3075 -- Shared_Var_Assign_Proc (Node22)
3076 -- Present in variables. Set non-Empty only if Is_Shared_Passive is
3077 -- set, in which case this is the entity for the shared memory assign
3078 -- routine. See Exp_Smem for full details.
3080 -- Shared_Var_Read_Proc (Node15)
3081 -- Present in variables. Set non-Empty only if Is_Shared_Passive is
3082 -- set, in which case this is the entity for the shared memory read
3083 -- routine. See Exp_Smem for full details.
3085 -- Size_Check_Code (Node19)
3086 -- Present in constants and variables. Normally Empty. Set if code is
3087 -- generated to check the size of the object. This field is used to
3088 -- suppress this code if a subsequent address clause is encountered.
3090 -- Size_Clause (synthesized)
3091 -- Applies to all entities. If a size clause is present in the rep
3092 -- item chain for an entity then the attribute definition clause node
3093 -- for the size clause is returned. Otherwise Size_Clause returns Empty
3094 -- if no item is present. Usually this is only meaningful if the flag
3095 -- Has_Size_Clause is set. This is because when the representation item
3096 -- chain is copied for a derived type, it can inherit a size clause that
3097 -- is not applicable to the entity.
3099 -- Size_Depends_On_Discriminant (Flag177)
3100 -- Present in all entities for types and subtypes. Indicates that the
3101 -- size of the type depends on the value of one or more discriminants.
3102 -- Currently, this flag is only set in front end layout mode for arrays
3103 -- which have one or more bounds depending on a discriminant value.
3105 -- Size_Known_At_Compile_Time (Flag92)
3106 -- Present in all entities for types and subtypes. Indicates that the
3107 -- size of objects of the type is known at compile time. This flag is
3108 -- used to optimize some generated code sequences, and also to enable
3109 -- some error checks (e.g. disallowing component clauses on variable
3110 -- length objects. It is set conservatively (i.e. if it is True, the
3111 -- size is certainly known at compile time, if it is False, then the
3112 -- size may or may not be known at compile time, but the code will
3113 -- assume that it is not known).
3115 -- Small_Value (Ureal21)
3116 -- Present in fixed point types. Points to the universal real for the
3117 -- Small of the type, either as given in a representation clause, or
3118 -- as computed (as a power of two) by the compiler.
3120 -- Spec_Entity (Node19)
3121 -- Present in package body entities. Points to corresponding package
3122 -- spec entity. Also present in subprogram body parameters in the
3123 -- case where there is a separate spec, where this field references
3124 -- the corresponding parameter entities in the spec.
3126 -- Storage_Size_Variable (Node15) [implementation base type only]
3127 -- Present in access types and task type entities. This flag is set
3128 -- if a valid and effective pragma Storage_Size applies to the base
3129 -- type. Points to the entity for a variable that is created to
3130 -- hold the value given in a Storage_Size pragma for an access
3131 -- collection or a task type. Note that in the access type case,
3132 -- this field is present only in the root type (since derived types
3133 -- share the same storage pool).
3135 -- Stored_Constraint (Elist23)
3136 -- Present in entities that can have discriminants (concurrent types
3137 -- subtypes, record types and subtypes, private types and subtypes,
3138 -- limited private types and subtypes and incomplete types). Points
3139 -- to an element list containing the expressions for each of the
3140 -- stored discriminants for the record (sub)type.
3142 -- Strict_Alignment (Flag145) [implementation base type only]
3143 -- Present in all type entities. Indicates that some containing part
3144 -- is either aliased or tagged. This prohibits packing the object
3145 -- tighter than its natural size and alignment.
3147 -- String_Literal_Length (Uint16)
3148 -- Present in string literal subtypes (which are created to correspond
3149 -- to string literals in the program). Contains the length of the string
3152 -- String_Literal_Low_Bound (Node15)
3153 -- Present in string literal subtypes (which are created to correspond
3154 -- to string literals in the program). Contains an expression whose
3155 -- value represents the low bound of the literal. This is a copy of
3156 -- the low bound of the applicable index constraint if there is one,
3157 -- or a copy of the low bound of the index base type if not.
3159 -- Suppress_Elaboration_Warnings (Flag148)
3160 -- Present in all entities, relevant only for subprogram entities. If
3161 -- this flag is set then Sem_Elab will not generate elaboration warnings
3162 -- for the subprogram. Suppression of such warnings is automatic for
3163 -- subprograms for which elaboration checks are suppressed (without the
3164 -- need to set this flag), but the flag is also set for various internal
3165 -- entities (such as init procs) which are known not to generate any
3166 -- possible access before elaboration. (we need a clear description of
3167 -- how this flag differs in effect from Elaboration_Checks_Suppressed???)
3169 -- Suppress_Init_Proc (Flag105) [base type only]
3170 -- Present in all type entities. Set to suppress the generation of
3171 -- initialization procedures where they are known to be not needed.
3172 -- For example, the enumeration image table entity uses this flag.
3174 -- Suppress_Style_Checks (Flag165)
3175 -- Present in all entities. Suppresses any style checks specifically
3176 -- associated with the given entity if set.
3178 -- Task_Body_Procedure (Node24)
3179 -- Present in task types and subtypes. Points to the entity for
3180 -- the task body procedure (as further described in Exp_Ch9, task
3181 -- bodies are expanded into procedures). A convenient function to
3182 -- retrieve this field is Sem_Util.Get_Task_Body_Procedure.
3184 -- First_Tag_Component (synthesized)
3185 -- Applies to tagged record types, returns the entity for the first
3186 -- _Tag field in this record.
3188 -- Next_Tag_Component (synthesized)
3189 -- Applies to components of tagged record types. Given a _Tag field
3190 -- of a record, returns the next _Tag field in this record.
3192 -- Treat_As_Volatile (Flag41)
3193 -- Present in all type entities, and also in constants, components and
3194 -- variables. Set if this entity is to be treated as volatile for code
3195 -- generation purposes. Always set if Is_Volatile is set, but can also
3196 -- be set as a result of situations (such as address overlays) where
3197 -- the front end wishes to force volatile handling to inhibit aliasing
3198 -- optimization which might be legally ok, but is undesirable. Note
3199 -- that the back end always tests this flag rather than Is_Volatile.
3200 -- The front end tests Is_Volatile if it is concerned with legality
3201 -- checks associated with declared volatile variables, but if the test
3202 -- is for the purposes of suppressing optimizations, then the front
3203 -- end should test Treat_As_Volatile rather than Is_Volatile.
3205 -- Type_High_Bound (synthesized)
3206 -- Applies to scalar types. Returns the tree node (Node_Id) that
3207 -- contains the high bound of a scalar type. The returned value is a
3208 -- literal for a base type, but may be an expression in the case of a
3209 -- scalar type with dynamic bounds. Note that in the case of a fixed
3210 -- point type, the high bound is in units of small, and is an integer.
3212 -- Type_Low_Bound (synthesized)
3213 -- Applies to scalar types. Returns the tree node (Node_Id) that
3214 -- contains the low bound of a scalar type. The returned value is a
3215 -- literal for a base type, but may be an expression in the case of a
3216 -- scalar type with dynamic bounds. Note that in the case of a fixed
3217 -- point type, the low bound is in units of small, and is an integer.
3219 -- Underlying_Full_View (Node19)
3220 -- Present in private subtypes that are the completion of other private
3221 -- types, or in private types that are derived from private subtypes.
3222 -- If the full view of a private type T is derived from another
3223 -- private type with discriminants Td, the full view of T is also
3224 -- private, and there is no way to attach to it a further full view that
3225 -- would convey the structure of T to the back end. The Underlying_Full_
3226 -- View is an attribute of the full view that is a subtype of Td with
3227 -- the same constraint as the declaration for T. The declaration for this
3228 -- subtype is built at the point of the declaration of T, either as a
3229 -- completion, or as a subtype declaration where the base type is private
3230 -- and has a private completion. If Td is already constrained, then its
3231 -- full view can serve directly as the full view of T.
3233 -- Underlying_Type (synthesized)
3234 -- Applies to all entities. This is the identity function except in
3235 -- the case where it is applied to an incomplete or private type,
3236 -- in which case it is the underlying type of the type declared by
3237 -- the completion, or Empty if the completion has not yet been
3238 -- encountered and analyzed.
3240 -- Note: the reason this attribute applies to all entities, and not
3241 -- just types, is to legitimize code where Underlying_Type is applied
3242 -- to an entity which may or may not be a type, with the intent that
3243 -- if it is a type, its underlying type is taken.
3245 -- Unset_Reference (Node16)
3246 -- Present in variables and out parameters. This is normally Empty.
3247 -- It is set to point to an identifier that represents a reference
3248 -- to the entity before any value has been set. Only the first such
3249 -- reference is identified. This field is used to generate a warning
3250 -- message if necessary (see Sem_Warn.Check_Unset_Reference).
3252 -- Uses_Sec_Stack (Flag95)
3253 -- Present in scope entities (blocks,functions, procedures, tasks,
3254 -- entries). Set to True when secondary stack is used in this scope and
3255 -- must be released on exit unless Sec_Stack_Needed_For_Return is set.
3257 -- Vax_Float (Flag151) [base type only]
3258 -- Present in all type entities. Set only on the base type of float
3259 -- types with Vax format. The particular format is determined by the
3260 -- Digits_Value value which is 6,9,15 for F_Float, D_Float, G_Float.
3262 -- Warnings_Off (Flag96)
3263 -- Present in all entities. Set if a pragma Warnings (Off, entity-name)
3264 -- is used to suppress warnings for a given entity. It is also used by
3265 -- the compiler in some situations to kill spurious warnings.
3267 -- Was_Hidden (Flag196)
3268 -- Present in all entities. Used to save the value of the Is_Hidden
3269 -- attribute when the limited-view is installed (Ada 2005: AI-217).
3271 -- Wrapped_Entity (Node27)
3272 -- Present in an E_Procedure classified as a Is_Primitive_Wrapper. Set
3273 -- to the entity that is being wrapped.
3279 -- The following three entity kinds are introduced by the corresponding
3280 -- type definitions:
3283 -- E_General_Access_Type,
3284 -- E_Anonymous_Access_Subprogram_Type,
3285 -- E_Anonymous_Access_Protected_Subprogram_Type
3286 -- E_Anonymous_Access_Type.
3288 -- In addition, we define the kind E_Allocator_Type to label
3289 -- allocators. This is because special resolution rules apply to this
3290 -- construct. Eventually the constructs are labeled with the access
3291 -- type imposed by the context. Gigi should never see the type
3294 -- Similarly, the type E_Access_Attribute_Type is used as the initial
3295 -- kind associated with an access attribute. After resolution a specific
3296 -- access type will be established as determined by the context.
3298 -- Finally, the type Any_Access is used to label -null- during type
3299 -- resolution. Any_Access is also replaced by the context type after
3302 --------------------------------
3303 -- Classification of Entities --
3304 --------------------------------
3306 -- The classification of program entities which follows is a refinement of
3307 -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
3308 -- different type classes. Ada 95 entities include class wide types,
3309 -- protected types, subprogram types, generalized access types, generic
3310 -- formal derived types and generic formal packages.
3312 -- The order chosen for these kinds allows us to classify related entities
3313 -- so that they are contiguous. As a result, they do not appear in the
3314 -- exact same order as their order of first appearance in the LRM (For
3315 -- example, private types are listed before packages). The contiguity
3316 -- allows us to define useful subtypes (see below) such as type entities,
3317 -- overloaded entities, etc.
3319 -- Each entity (explicitly or implicitly declared) has a kind, which is
3320 -- a value of the following type:
3322 type Entity_Kind is (
3325 -- The initial Ekind value for a newly created entity. Also used as
3326 -- the Ekind for Standard_Void_Type, a type entity in Standard used
3327 -- as a dummy type for the return type of a procedure (the reason we
3328 -- create this type is to share the circuits for performing overload
3329 -- resolution on calls).

3339 -- Components of a record declaration, private declarations of
3340 -- protected objects.

3408 -- integer subtype created by an integer type declaration.
3410 E_Signed_Integer_Subtype,
3411 -- Signed integer subtype, created by either an integer subtype or
3412 -- integer type declaration (in the latter case an integer type is
3413 -- created for the base type, and this is the first named subtype).
3415 E_Modular_Integer_Type,

3417 -- integer subtype created by a modular integer type declaration.
3419 E_Modular_Integer_Subtype,

3428 E_Ordinary_Fixed_Point_Subtype,

3471 -- 'Unrestricted_Access and Unchecked_Access)

3476 -- rules apply to these constructs. On the resolution pass, this type

3591 -- to declare a subtype of a protected type.
3598 -- The type of an exception created by an exception declaration
3601 -- This is the designated type of an Access_To_Subprogram. Has type
3602 -- and signature like a subprogram entity, so can appear in calls,
3603 -- which are resolved like regular calls, except that such an entity
3604 -- is not overloadable.

3607 -- Overloadable Entities --
3608 ---------------------------
3610 E_Enumeration_Literal,
3611 -- An enumeration literal, created by the use of the literal in an
3612 -- enumeration type definition.
3615 -- A function, created by a function declaration or a function body
3616 -- that acts as its own declaration.
3619 -- A predefined operator, appearing in Standard, or an implicitly
3620 -- defined concatenation operator created whenever an array is
3621 -- declared. We do not make normal derived operators explicit in
3622 -- the tree, but the concatenation operators are made explicit.
3625 -- A procedure, created by a procedure declaration or a procedure
3626 -- body that acts as its own declaration.
3629 -- An entry, created by an entry declaration in a task or protected
3632 --------------------
3633 -- Other Entities --
3634 --------------------
3637 -- An entry family, created by an entry family declaration in a
3638 -- task or protected type definition.
3641 -- A block identifier, created by an explicit or implicit label on
3642 -- a block or declare statement.
3644 E_Entry_Index_Parameter,
3645 -- An entry index parameter created by an entry index specification
3646 -- for the body of a protected entry family.
3649 -- An exception created by an exception declaration. The exception
3650 -- itself uses E_Exception for the Ekind, the implicit type that is
3651 -- created to represent its type uses the Ekind E_Exception_Type.
3654 -- A generic function. This is the entity for a generic function
3655 -- created by a generic subprogram declaration.
3657 E_Generic_Procedure,
3658 -- A generic function. This is the entity for a generic procedure
3659 -- created by a generic subprogram declaration.
3662 -- A generic package, this is the entity for a generic package created
3663 -- by a generic package declaration.
3666 -- The defining entity for a label. Note that this is created by the
3667 -- implicit label declaration, not the occurrence of the label itself,
3668 -- which is simply a direct name referring to the label.
3671 -- A loop identifier, created by an explicit or implicit label on a
3675 -- A package, created by a package declaration
3678 -- A package body. This entity serves only limited functions, since
3679 -- most semantic analysis uses the package entity (E_Package). However
3680 -- there are some attributes that are significant for the body entity.
3681 -- For example, collection of exception handlers.
3684 -- A protected object, created by an object declaration that declares
3685 -- an object of a protected type.
3688 -- A protected body. This entity serves almost no function, since all
3689 -- semantic analysis uses the protected entity (E_Protected_Type)
3692 -- A task body. This entity serves almost no function, since all
3693 -- semantic analysis uses the protected entity (E_Task_Type).
3696 -- A subprogram body. Used when a subprogram has a separate declaration
3697 -- to represent the entity for the body. This entity serves almost no
3698 -- function, since all semantic analysis uses the subprogram entity
3699 -- for the declaration (E_Function or E_Procedure).

4929 -- Since E_Void is the initial Ekind value of an entity when it is first

4932 -- are many instances in which fields of an E_Void entity are set in the
4933 -- code prior to setting the Ekind field. This is not well documented or
4934 -- well controlled, and needs cleaning up later. Meanwhile, the access
4935 -- procedures in the body of Einfo permit many, but not all, attributes
4936 -- to be applied to an E_Void entity, precisely so that this kind of
4937 -- pre-setting of attributes works. This is really a hole in the dynamic
4938 -- type checking, since there is no assurance that the eventual Ekind
4939 -- value will be appropriate for the attributes set, and the consequence
4940 -- is that the dynamic type checking in the Einfo body is unnecessarily

4943 ---------------------------------
4944 -- Component_Alignment Control --
4945 ---------------------------------
4947 -- There are four types of alignment possible for array and record
4948 -- types, and a field in the type entities contains a value of the
4949 -- following type indicating which alignment choice applies. For full
4950 -- details of the meaning of these aligment types, see description
4951 -- of the Component_Alignment pragma
4953 type Component_Alignment_Kind is (
4954 Calign_Default, -- default alignment
4955 Calign_Component_Size, -- natural alignment for component size
4956 Calign_Component_Size_4, -- natural for size <= 4, 4 for size >= 4
4957 Calign_Storage_Unit); -- all components byte aligned
4963 -- In addition to attributes that are stored as plain data, other
4964 -- attributes are procedural, and require some small amount of
4965 -- computation. Of course, from the point of view of a user of this
4966 -- package, the distinction is not visible (even the field information
4967 -- provided below should be disregarded, as it is subject to change
4968 -- without notice!). A number of attributes appear as lists: lists of
4969 -- formals, lists of actuals, of discriminants, etc. For these, pairs
4970 -- of functions are defined, which take the form:
4972 -- function First_Thing (E : Enclosing_Construct) return Thing;
4973 -- function Next_Thing (T : Thing) return Thing;
4975 -- The end of iteration is always signaled by a value of Empty, so that
4976 -- loops over these chains invariably have the form:
4980 -- This := First_Thing (E);
4982 -- while Present (This) loop
4983 -- Do_Something_With (This);
4985 -- This := Next_Thing (This);

4989 -- Handling of Check Suppression --
4990 -----------------------------------
4992 -- There are three ways that checks can be suppressed:
4994 -- 1. At the command line level
4995 -- 2. At the scope level.
4996 -- 3. At the entity level.
4998 -- See spec of Sem in sem.ads for details of the data structures used
4999 -- to keep track of these various methods for suppressing checks.
5001 -------------------------------
5002 -- Handling of Discriminants --
5003 -------------------------------
5005 -- During semantic processing, discriminants are separate entities which
5006 -- reflect the semantic properties and allowed usage of discriminants in
5009 -- In the case of discriminants used as bounds, the references are handled
5010 -- directly, since special processing is needed in any case. However, there
5011 -- are two circumstances in which discriminants are referenced in a quite
5012 -- general manner, like any other variables:
5014 -- In initialization expressions for records. Note that the expressions
5015 -- used in Priority, Storage_Size, and Task_Info pragmas are effectively
5016 -- in this category, since these pragmas are converted to initialized
5017 -- record fields in the Corresponding_Record_Type.
5019 -- In task and protected bodies, where the discriminant values may be
5020 -- referenced freely within these bodies. Discriminants can also appear
5021 -- in bounds of entry families and in defaults of operations.
5023 -- In both these cases, the discriminants must be treated essentially as
5024 -- objects. The following approach is used to simplify and minimize the
5025 -- special processing that is required.
5027 -- When a record type with discriminants is processed, the semantic
5028 -- processing creates the entities for the discriminants. It also creates
5029 -- an additional set of entities, called discriminals, one for each of
5030 -- the discriminants, and the Discriminal field of the discriminant entity
5031 -- points to this additional entity, which is initially created as an
5032 -- uninitialized (E_Void) entity.
5034 -- During expansion of expressions, any discriminant reference is replaced
5035 -- by a reference to the corresponding discriminal. When the initialization
5036 -- procedure for the record is created (there will always be one, since
5037 -- discriminants are present, see Exp_Ch3 for further details), the
5038 -- discriminals are used as the entities for the formal parameters of
5039 -- this initialization procedure. The references to these discriminants
5040 -- have already been replaced by references to these discriminals, which
5041 -- are now the formal parameters corresponding to the required objects.
5043 -- In the case of a task or protected body, the semantics similarly
5044 -- creates a set of discriminals for the discriminants of the task or
5045 -- protected type. When the procedure is created for the task body,
5046 -- the parameter passed in is a reference to the task value type, which
5047 -- contains the required discriminant values. The expander creates a
5048 -- set of declarations of the form:
5050 -- discriminal : constant dtype renames _Task.discriminant;
5052 -- where discriminal is the discriminal entity referenced by the task
5053 -- discriminant, and _Task is the task value passed in as the parameter.
5054 -- Again, any references to discriminants in the task body have been
5055 -- replaced by the discriminal reference, which is now an object that
5056 -- contains the required value.
5058 -- This approach for tasks means that two sets of discriminals are needed
5059 -- for a task type, one for the initialization procedure, and one for the
5060 -- task body. This works out nicely, since the semantics allocates one set
5061 -- for the task itself, and one set for the corresponding record.
5063 -- The one bit of trickiness arises in making sure that the right set of
5064 -- discriminals is used at the right time. First the task definition is
5065 -- processed. Any references to discriminants here are replaced by the
5066 -- the corresponding *task* discriminals (the record type doesn't even
5067 -- exist yet, since it is constructed as part of the expansion of the
5068 -- task declaration, which happens after the semantic processing of the
5069 -- task definition). The discriminants to be used for the corresponding
5070 -- record are created at the same time as the other discriminals, and
5071 -- held in the CR_Discriminant field of the discriminant. A use of the
5072 -- discriminant in a bound for an entry family is replaced with the CR_
5073 -- discriminant because it controls the bound of the entry queue array
5074 -- which is a component of the corresponding record.
5076 -- Just before the record initialization routine is constructed, the
5077 -- expander exchanges the task and record discriminals. This has two
5078 -- effects. First the generation of the record initialization routine
5079 -- uses the discriminals that are now on the record, which is the set
5080 -- that used to be on the task, which is what we want.
5082 -- Second, a new set of (so far unused) discriminals is now on the task
5083 -- discriminants, and it is this set that will be used for expanding the
5084 -- task body, and also for the discriminal declarations at the start of
5087 ---------------------------------------
5088 -- Private data in protected objects --
5089 ---------------------------------------
5091 -- Private object declarations in protected types pose problems
5092 -- similar to those of discriminants. They are expanded to components
5093 -- of a record which is passed as the parameter "_object" to expanded
5094 -- forms of all protected operations. As with discriminants, timing
5095 -- of this expansion is a problem. The sequence of statements for a
5096 -- protected operation is expanded before the operation itself, so the
5097 -- formal parameter for the record object containing the private data
5098 -- does not exist when the references to that data are expanded.
5100 -- For this reason, private data is handled in the same way as
5101 -- discriminants, expanding references to private data in protected
5102 -- operations (which appear as components) to placeholders which will
5103 -- eventually become renamings of the private selected components
5104 -- of the "_object" formal parameter. These placeholders are called
5105 -- "privals", by analogy to the "discriminals" used to implement
5106 -- discriminants. They are attached to the component declaration nodes
5107 -- representing the private object declarations of the protected type.
5109 -- As with discriminals, each protected subprogram needs a unique set
5110 -- of privals, since they must refer to renamings of components of a
5111 -- formal parameter of that operation. Entry bodies need another set,
5112 -- which they all share and which is associated with renamings in the
5113 -- Service_Entries procedure for the protected type (this is not yet
5114 -- implemented???). This means that we must associate a new set of
5115 -- privals (and discriminals) with the private declarations after
5116 -- the body of a protected subprogram is processed.
5118 -- The last complication is the presence of discriminants and discriminated
5119 -- components. In the corresponding record, the components are constrained
5120 -- by the discriminants of the record, but within each protected operation
5121 -- they are constrained by the discriminants of the actual. The actual
5122 -- subtypes of those components are constructed as for other unconstrained
5123 -- formals, but the privals are created before the formal object is added
5124 -- to the parameter list of the protected operation, so they carry the
5125 -- nominal subtype of the original component. After the protected operation
5126 -- is actually created (in the expansion of the protected body) we must
5127 -- patch the types of each prival occurrence with the proper actual subtype
5128 -- which is by now set. The Privals_Chain is used for this patching.
5134 -- The following type synonyms are used to tidy up the function and
5135 -- procedure declarations that follow, and also to make it possible
5136 -- to meet the requirement for the XEINFO utility that all function
5137 -- specs must fit on a single source line.

5992 -- parameter instead, and appropriately convert it. There are also
5993 -- versions that implicitly initialize to the appropriate "not set"
5994 -- value. The not set (unknown) values are as follows:
5997 -- Component_Size Uint_0
5998 -- Component_Bit_Offset No_Uint
5999 -- Digits_Value Uint_0
6001 -- Normalized_First_Bit No_Uint
6002 -- Normalized_Position No_Uint
6003 -- Normalized_Position_Max No_Uint
6006 -- It would be cleaner to use No_Uint in all these cases, but historically
6007 -- we chose to use Uint_0 at first, and the change over will take time ???
6008 -- This is particularly true for the RM_Size field, where a value of zero
6009 -- is legitimate and causes some kludges around the code.
