32 -- This package defines the structure of the abstract syntax tree. The Tree
33 -- package provides a basic tree structure. Sinfo describes how this structure
34 -- is used to represent the syntax of an Ada program.
36 -- The grammar in the RM is followed very closely in the tree design, and is
37 -- repeated as part of this source file.
39 -- The tree contains not only the full syntactic representation of the
40 -- program, but also the results of semantic analysis. In particular, the
41 -- nodes for defining identifiers, defining character literals and defining
42 -- operator symbols, collectively referred to as entities, represent what
43 -- would normally be regarded as the symbol table information. In addition a
44 -- number of the tree nodes contain semantic information.
46 -- WARNING: Several files are automatically generated from this package.

57 -- Making Changes to This File --
58 ---------------------------------
60 -- If changes are made to this file, a number of related steps must be
61 -- carried out to ensure consistency. First, if a field access function is
62 -- added, it appears in seven places:
64 -- The documentation associated with the node
65 -- The spec of the access function in sinfo.ads
66 -- The body of the access function in sinfo.adb
67 -- The pragma Inline at the end of sinfo.ads for the access function
68 -- The spec of the set procedure in sinfo.ads
69 -- The body of the set procedure in sinfo.adb
70 -- The pragma Inline at the end of sinfo.ads for the set procedure
72 -- The field chosen must be consistent in all places, and, for a node that
73 -- is a subexpression, must not overlap any of the standard expression
76 -- In addition, if any of the standard expression fields is changed, then
77 -- the utility program which creates the Treeprs spec (in file treeprs.ads)
78 -- must be updated appropriately, since it special cases expression fields.
80 -- If a new tree node is added, then the following changes are made
82 -- Add it to the documentation in the appropriate place
83 -- Add its fields to this documentation section
84 -- Define it in the appropriate classification in Node_Kind
85 -- In the body (sinfo), add entries to the access functions for all
86 -- its fields (except standard expression fields) to include the new
87 -- node in the checks.
88 -- Add an appropriate section to the case statement in sprint.adb
89 -- Add an appropriate section to the case statement in sem.adb
90 -- Add an appropriate section to the case statement in exp_util.adb
91 -- (Insert_Actions procedure)
92 -- For a subexpression, add an appropriate section to the case
93 -- statement in sem_eval.adb
94 -- For a subexpression, add an appropriate section to the case
95 -- statement in sem_res.adb
97 -- Finally, four utility programs must be run:
99 -- Run CSinfo to check that you have made the changes consistently. It
100 -- checks most of the rules given above, with clear error messages. This
101 -- utility reads sinfo.ads and sinfo.adb and generates a report to
104 -- Run XSinfo to create sinfo.h, the corresponding C header. This
105 -- utility reads sinfo.ads and generates sinfo.h. Note that it does
106 -- not need to read sinfo.adb, since the contents of the body are
107 -- algorithmically determinable from the spec.
109 -- Run XTreeprs to create treeprs.ads, an updated version of the module
110 -- that is used to drive the tree print routine. This utility reads (but
111 -- does not modify) treeprs.adt, the template that provides the basic
112 -- structure of the file, and then fills in the data from the comments
115 -- Run XNmake to create nmake.ads and nmake.adb, the package body and
116 -- spec of the Nmake package which contains functions for constructing
119 -- All of the above steps except CSinfo are done automatically by the
120 -- build scripts when you do a full bootstrap.
122 -- Note: sometime we could write a utility that actually generated the body
123 -- of sinfo from the spec instead of simply checking it, since, as noted
124 -- above, the contents of the body can be determined from the spec.
126 --------------------------------
127 -- Implicit Nodes in the Tree --
128 --------------------------------
130 -- Generally the structure of the tree very closely follows the grammar as
131 -- defined in the RM. However, certain nodes are omitted to save space and
132 -- simplify semantic processing. Two general classes of such omitted nodes
135 -- If the only possibilities for a non-terminal are one or more other
136 -- non-terminals (i.e. the rule is a "skinny" rule), then usually the
137 -- corresponding node is omitted from the tree, and the target construct
138 -- appears directly. For example, a real type definition is either
139 -- floating point definition or a fixed point definition. No explicit node
140 -- appears for real type definition. Instead either the floating point
141 -- definition or fixed point definition appears directly.
143 -- If a non-terminal corresponds to a list of some other non-terminal
144 -- (possibly with separating punctuation), then usually it is omitted from
145 -- the tree, and a list of components appears instead. For example,
146 -- sequence of statements does not appear explicitly in the tree. Instead
147 -- a list of statements appears directly.
149 -- Some additional cases of omitted nodes occur and are documented
150 -- individually. In particular, many nodes are omitted in the tree
151 -- generated for an expression.
153 -------------------------------------------
154 -- Handling of Defining Identifier Lists --
155 -------------------------------------------
157 -- In several declarative forms in the syntax, lists of defining
158 -- identifiers appear (object declarations, component declarations, number
159 -- declarations etc.)
161 -- The semantics of such statements are equivalent to a series of identical
162 -- declarations of single defining identifiers (except that conformance
163 -- checks require the same grouping of identifiers in the parameter case).
165 -- To simplify semantic processing, the parser breaks down such multiple
166 -- declaration cases into sequences of single declarations, duplicating
167 -- type and initialization information as required. The flags More_Ids and
168 -- Prev_Ids are used to record the original form of the source in the case
169 -- where the original source used a list of names, More_Ids being set on
170 -- all but the last name and Prev_Ids being set on all but the first name.
171 -- These flags are used to reconstruct the original source (e.g. in the
172 -- Sprint package), and also are included in the conformance checks, but
173 -- otherwise have no semantic significance.
175 -- Note: the reason that we use More_Ids and Prev_Ids rather than
176 -- First_Name and Last_Name flags is so that the flags are off in the
177 -- normal one identifier case, which minimizes tree print output.
179 -----------------------
180 -- Use of Node Lists --
181 -----------------------
183 -- With a few exceptions, if a construction of the form {non-terminal}
184 -- appears in the tree, lists are used in the corresponding tree node (see
185 -- package Nlists for handling of node lists). In this case a field of the
186 -- parent node points to a list of nodes for the non-terminal. The field
187 -- name for such fields has a plural name which always ends in "s". For
188 -- example, a case statement has a field Alternatives pointing to list of
189 -- case statement alternative nodes.
191 -- Only fields pointing to lists have names ending in "s", so generally the
192 -- structure is strongly typed, fields not ending in s point to single
193 -- nodes, and fields ending in s point to lists.
195 -- The following example shows how a traversal of a list is written. We
196 -- suppose here that Stmt points to a N_Case_Statement node which has a
197 -- list field called Alternatives:
199 -- Alt := First (Alternatives (Stmt));
200 -- while Present (Alt) loop
202 -- -- processing for case statement alternative Alt
204 -- Alt := Next (Alt);
207 -- The Present function tests for Empty, which in this case signals the end
208 -- of the list. First returns Empty immediately if the list is empty.
209 -- Present is defined in Atree, First and Next are defined in Nlists.
211 -- The exceptions to this rule occur with {DEFINING_IDENTIFIERS} in all
212 -- contexts, which is handled as described in the previous section, and
213 -- with {,library_unit_NAME} in the N_With_Clause mode, which is handled
214 -- using the First_Name and Last_Name flags, as further detailed in the
215 -- description of the N_With_Clause node.
221 -- Pragmas can appear in many different context, but are not included in
222 -- the grammar. Still they must appear in the tree, so they can be properly
225 -- Two approaches are used. In some cases, an extra field is defined in an
226 -- appropriate node that contains a list of pragmas appearing in the
227 -- expected context. For example pragmas can appear before an
228 -- Accept_Alternative in a Selective_Accept_Statement, and these pragmas
229 -- appear in the Pragmas_Before field of the N_Accept_Alternative node.
231 -- The other approach is to simply allow pragmas to appear in syntactic
232 -- lists where the grammar (of course) does not include the possibility.
233 -- For example, the Variants field of an N_Variant_Part node points to a
234 -- list that can contain both N_Pragma and N_Variant nodes.
236 -- To make processing easier in the latter case, the Nlists package
237 -- provides a set of routines (First_Non_Pragma, Last_Non_Pragma,
238 -- Next_Non_Pragma, Prev_Non_Pragma) that allow such lists to be handled
239 -- ignoring all pragmas.
241 -- In the case of the variants list, we can either write:
243 -- Variant := First (Variants (N));
244 -- while Present (Variant) loop
246 -- Variant := Next (Variant);
251 -- Variant := First_Non_Pragma (Variants (N));
252 -- while Present (Variant) loop
254 -- Variant := Next_Non_Pragma (Variant);
257 -- In the first form of the loop, Variant can either be an N_Pragma or an
258 -- N_Variant node. In the second form, Variant can only be N_Variant since
259 -- all pragmas are skipped.
261 ---------------------
262 -- Optional Fields --
263 ---------------------
265 -- Fields which correspond to a section of the syntax enclosed in square
266 -- brackets are generally omitted (and the corresponding field set to Empty
267 -- for a node, or No_List for a list). The documentation of such fields
268 -- notes these cases. One exception to this rule occurs in the case of
269 -- possibly empty statement sequences (such as the sequence of statements
270 -- in an entry call alternative). Such cases appear in the syntax rules as
271 -- [SEQUENCE_OF_STATEMENTS] and the fields corresponding to such optional
272 -- statement sequences always contain an empty list (not No_List) if no
273 -- statements are present.
275 -- Note: the utility program that constructs the body and spec of the Nmake
276 -- package relies on the format of the comments to determine if a field
277 -- should have a default value in the corresponding make routine. The rule
278 -- is that if the first line of the description of the field contains the
279 -- string "(set to xxx if", then a default value of xxx is provided for
280 -- this field in the corresponding Make_yyy routine.
282 -----------------------------------
283 -- Note on Body/Spec Terminology --
284 -----------------------------------
286 -- In informal discussions about Ada, it is customary to refer to package
287 -- and subprogram specs and bodies. However, this is not technically
288 -- correct, what is normally referred to as a spec or specification is in
289 -- fact a package declaration or subprogram declaration. We are careful in
290 -- GNAT to use the correct terminology and in particular, the full word
291 -- specification is never used as an incorrect substitute for declaration.
292 -- The structure and terminology used in the tree also reflects the grammar
293 -- and thus uses declaration and specification in the technically correct
296 -- However, there are contexts in which the informal terminology is useful.
297 -- We have the word "body" to refer to the Interp_Etype declared by the
298 -- declaration of a unit body, and in some contexts we need similar term to
299 -- refer to the entity declared by the package or subprogram declaration,
300 -- and simply using declaration can be confusing since the body also has a
303 -- An example of such a context is the link between the package body and
304 -- its declaration. With_Declaration is confusing, since the package body
305 -- itself is a declaration.
307 -- To deal with this problem, we reserve the informal term Spec, i.e. the
308 -- popular abbreviation used in this context, to refer to the entity
309 -- declared by the package or subprogram declaration. So in the above
310 -- example case, the field in the body is called With_Spec.
312 -- Another important context for the use of the word Spec is in error
313 -- messages, where a hyper-correct use of declaration would be confusing to
314 -- a typical Ada programmer, and even for an expert programmer can cause
315 -- confusion since the body has a declaration as well.
319 -- Declaration always refers to the syntactic entity that is called
320 -- a declaration. In particular, subprogram declaration
321 -- and package declaration are used to describe the
322 -- syntactic entity that includes the semicolon.
324 -- Specification always refers to the syntactic entity that is called
325 -- a specification. In particular, the terms procedure
326 -- specification, function specification, package
327 -- specification, subprogram specification always refer
328 -- to the syntactic entity that has no semicolon.
330 -- Spec is an informal term, used to refer to the entity
331 -- that is declared by a task declaration, protected
332 -- declaration, generic declaration, subprogram
333 -- declaration or package declaration.
335 -- This convention is followed throughout the GNAT documentation
336 -- both internal and external, and in all error message text.
338 ------------------------
339 -- Internal Use Nodes --
340 ------------------------
342 -- These are Node_Kind settings used in the internal implementation which
343 -- are not logically part of the specification.
346 -- Completely unused entry at the start of the enumeration type. This
347 -- is inserted so that no legitimate value is zero, which helps to get
348 -- better debugging behavior, since zero is a likely uninitialized value).
351 -- Completely unused entry at the end of the enumeration type. This is
352 -- handy so that arrays with Node_Kind as the index type have an extra
353 -- entry at the end (see for example the use of the Pchar_Pos_Array in
354 -- Treepr, where the extra entry provides the limit value when dealing with
355 -- the last used entry in the array).
357 -----------------------------------------
358 -- Note on the settings of Sloc fields --
359 -----------------------------------------
361 -- The Sloc field of nodes that come from the source is set by the parser.
362 -- For internal nodes, and nodes generated during expansion the Sloc is
363 -- usually set in the call to the constructor for the node. In general the
364 -- Sloc value chosen for an internal node is the Sloc of the source node
365 -- whose processing is responsible for the expansion. For example, the Sloc
366 -- of an inherited primitive operation is the Sloc of the corresponding
367 -- derived type declaration.
369 -- For the nodes of a generic instantiation, the Sloc value is encoded to
370 -- represent both the original Sloc in the generic unit, and the Sloc of
371 -- the instantiation itself. See Sinput.ads for details.
373 -- Subprogram instances create two callable entities: one is the visible
374 -- subprogram instance, and the other is an anonymous subprogram nested
375 -- within a wrapper package that contains the renamings for the actuals.
376 -- Both of these entities have the Sloc of the defining entity in the
377 -- instantiation node. This simplifies some ASIS queries.
379 -----------------------
380 -- Field Definitions --
381 -----------------------
383 -- In the following node definitions, all fields, both syntactic and
384 -- semantic, are documented. The one exception is in the case of entities
385 -- (defining identifiers, character literals and operator symbols), where
386 -- the usage of the fields depends on the entity kind. Entity fields are
387 -- fully documented in the separate package Einfo.
389 -- In the node definitions, three common sets of fields are abbreviated to
390 -- save both space in the documentation, and also space in the string
391 -- (defined in Tree_Print_Strings) used to print trees. The following
392 -- abbreviations are used:
394 -- Note: the utility program that creates the Treeprs spec (in the file
395 -- xtreeprs.adb) knows about the special fields here, so it must be
396 -- modified if any change is made to these fields.
398 -- "plus fields for binary operator"
399 -- Chars (Name1) Name_Id for the operator
400 -- Left_Opnd (Node2) left operand expression
401 -- Right_Opnd (Node3) right operand expression
402 -- Entity (Node4-Sem) defining entity for operator
403 -- Associated_Node (Node4-Sem) for generic processing
404 -- Do_Overflow_Check (Flag17-Sem) set if overflow check needed
405 -- Has_Private_View (Flag11-Sem) set in generic units.
407 -- "plus fields for unary operator"
408 -- Chars (Name1) Name_Id for the operator
409 -- Right_Opnd (Node3) right operand expression
410 -- Entity (Node4-Sem) defining entity for operator
411 -- Associated_Node (Node4-Sem) for generic processing
412 -- Do_Overflow_Check (Flag17-Sem) set if overflow check needed
413 -- Has_Private_View (Flag11-Sem) set in generic units.
415 -- "plus fields for expression"
416 -- Paren_Count number of parentheses levels
417 -- Etype (Node5-Sem) type of the expression
418 -- Is_Overloaded (Flag5-Sem) >1 type interpretation exists
419 -- Is_Static_Expression (Flag6-Sem) set for static expression
420 -- Raises_Constraint_Error (Flag7-Sem) evaluation raises CE
421 -- Must_Not_Freeze (Flag8-Sem) set if must not freeze
422 -- Do_Range_Check (Flag9-Sem) set if a range check needed
423 -- Assignment_OK (Flag15-Sem) set if modification is OK
424 -- Is_Controlling_Actual (Flag16-Sem) set for controlling argument
426 -- Note: see under (EXPRESSION) for further details on the use of
427 -- the Paren_Count field to record the number of parentheses levels.
429 -- Node_Kind is the type used in the Nkind field to indicate the node kind.
430 -- The actual definition of this type is given later (the reason for this
431 -- is that we want the descriptions ordered by logical chapter in the RM,
432 -- but the type definition is reordered to facilitate the definition of
433 -- some subtype ranges. The individual descriptions of the nodes show how
434 -- the various fields are used in each node kind, as well as providing
435 -- logical names for the fields. Functions and procedures are provided for
436 -- accessing and setting these fields using these logical names.
438 -----------------------
439 -- Gigi Restrictions --
440 -----------------------
442 -- The tree passed to Gigi is more restricted than the general tree form.
443 -- For example, as a result of expansion, most of the tasking nodes can
444 -- never appear. For each node to which either a complete or partial
445 -- restriction applies, a note entitled "Gigi restriction" appears which
446 -- documents the restriction.
448 -- Note that most of these restrictions apply only to trees generated when
449 -- code is being generated, since they involved expander actions that
452 ------------------------
453 -- Common Flag Fields --
454 ------------------------
456 -- The following flag fields appear in all nodes
459 -- This flag is used to indicate that a node (and all its children have
460 -- been analyzed. It is used to avoid reanalysis of a node that has
461 -- already been analyzed, both for efficiency and functional correctness
465 -- This flag is set if the node comes directly from an explicit construct
466 -- in the source. It is normally on for any nodes built by the scanner or
467 -- parser from the source program, with the exception that in a few cases
468 -- the parser adds nodes to normalize the representation (in particular
469 -- a null statement is added to a package body if there is no begin/end
470 -- initialization section.
472 -- Most nodes inserted by the analyzer or expander are not considered
473 -- as coming from source, so the flag is off for such nodes. In a few
474 -- cases, the expander constructs nodes closely equivalent to nodes
475 -- from the source program (e.g. the allocator built for build-in-place
476 -- case), and the Comes_From_Source flag is deliberately set.
479 -- This flag is used to avoid multiple error messages being posted on or
480 -- referring to the same node. This flag is set if an error message
481 -- refers to a node or is posted on its source location, and has the
482 -- effect of inhibiting further messages involving this same node.
484 -- Has_Dynamic_Length_Check (Flag10-Sem)
485 -- This flag is present on all nodes. It is set to indicate that one of
486 -- the routines in unit Checks has generated a length check action which
487 -- has been inserted at the flagged node. This is used to avoid the
488 -- generation of duplicate checks.
490 -- Has_Dynamic_Range_Check (Flag12-Sem)
491 -- This flag is present on all nodes. It is set to indicate that one of
492 -- the routines in unit Checks has generated a range check action which
493 -- has been inserted at the flagged node. This is used to avoid the
494 -- generation of duplicate checks.
496 -- Has_Local_Raise (Flag8-Sem)
497 -- Present in exception handler nodes. Set if the handler can be entered
498 -- via a local raise that gets transformed to a goto statement. This will
499 -- always be set if Local_Raise_Statements is non-empty, but can also be
500 -- set as a result of generation of N_Raise_xxx nodes, or flags set in
501 -- nodes requiring generation of back end checks.
503 ------------------------------------
504 -- Description of Semantic Fields --
505 ------------------------------------
507 -- The meaning of the syntactic fields is generally clear from their names
508 -- without any further description, since the names are chosen to
509 -- correspond very closely to the syntax in the reference manual. This
510 -- section describes the usage of the semantic fields, which are used to
511 -- contain additional information determined during semantic analysis.
513 -- ABE_Is_Certain (Flag18-Sem)
514 -- This flag is set in an instantiation node or a call node is determined
515 -- to be sure to raise an ABE. This is used to trigger special handling
516 -- of such cases, particularly in the instantiation case where we avoid
517 -- instantiating the body if this flag is set. This flag is also present
518 -- in an N_Formal_Package_Declaration_Node since formal package
519 -- declarations are treated like instantiations, but it is always set to
520 -- False in this context.
522 -- Accept_Handler_Records (List5-Sem)
523 -- This field is present only in an N_Accept_Alternative node. It is used
524 -- to temporarily hold the exception handler records from an accept
525 -- statement in a selective accept. These exception handlers will
526 -- eventually be placed in the Handler_Records list of the procedure
527 -- built for this accept (see Expand_N_Selective_Accept procedure in
528 -- Exp_Ch9 for further details).
530 -- Access_Types_To_Process (Elist2-Sem)
531 -- Present in N_Freeze_Entity nodes for Incomplete or private types.
532 -- Contains the list of access types which may require specific treatment
533 -- when the nature of the type completion is completely known. An example
534 -- of such treatment is the generation of the associated_final_chain.
536 -- Actions (List1-Sem)
537 -- This field contains a sequence of actions that are associated with the
538 -- node holding the field. See the individual node types for details of
539 -- how this field is used, as well as the description of the specific use
540 -- for a particular node type.
542 -- Activation_Chain_Entity (Node3-Sem)
543 -- This is used in tree nodes representing task activators (blocks,
544 -- subprogram bodies, package declarations, and task bodies). It is
545 -- initially Empty, and then gets set to point to the entity for the
546 -- declared Activation_Chain variable when the first task is declared.
547 -- When tasks are declared in the corresponding declarative region this
548 -- entity is located by name (its name is always _Chain) and the declared
549 -- tasks are added to the chain. Note that N_Extended_Return_Statement
550 -- does not have this attribute, although it does have an activation
551 -- chain. This chain is used to store the tasks temporarily, and is not
552 -- used for activating them. On successful completion of the return
553 -- statement, the tasks are moved to the caller's chain, and the caller
556 -- Acts_As_Spec (Flag4-Sem)
557 -- A flag set in the N_Subprogram_Body node for a subprogram body which
558 -- is acting as its own spec, except in the case of a library level
559 -- subprogram, in which case the flag is set on the parent compilation
560 -- unit node instead (see further description in spec of Lib package).
561 -- ??? Above note about Lib is dubious since lib.ads does not mention
562 -- Acts_As_Spec at all.
564 -- Actual_Designated_Subtype (Node4-Sem)
565 -- Present in N_Free_Statement and N_Explicit_Dereference nodes. If gigi
566 -- needs to known the dynamic constrained subtype of the designated
567 -- object, this attribute is set to that type. This is done for
568 -- N_Free_Statements for access-to-classwide types and access to
569 -- unconstrained packed array types, and for N_Explicit_Dereference when
570 -- the designated type is an unconstrained packed array and the
571 -- dereference is the prefix of a 'Size attribute reference.
573 -- Address_Warning_Posted (Flag18-Sem)
574 -- Present in N_Attribute_Definition nodes. Set to indicate that we have
575 -- posted a warning for the address clause regarding size or alignment
576 -- issues. Used to inhibit multiple redundant messages.
578 -- Aggregate_Bounds (Node3-Sem)
579 -- Present in array N_Aggregate nodes. If the bounds of the aggregate are
580 -- known at compile time, this field points to an N_Range node with those
581 -- bounds. Otherwise Empty.
583 -- All_Others (Flag11-Sem)
584 -- Present in an N_Others_Choice node. This flag is set for an others
585 -- exception where all exceptions are to be caught, even those that are
586 -- not normally handled (in particular the tasking abort signal). This
587 -- is used for translation of the at end handler into a normal exception
590 -- Aspect_Cancel (Flag11-Sem)
591 -- Processing of aspect specifications typically generates pragmas and
592 -- attribute definition clauses that are inserted into the tree after
593 -- the declaration node to get the desired aspect effect. In the case
594 -- of Boolean aspects that use "=> False" to cancel the effect of an
595 -- aspect (i.e. turn if off), the generated pragma has the Aspect_Cancel
596 -- flag set to indicate that the pragma operates in the opposite sense.
598 -- Aspect_Rep_Item (Node2-Sem)
599 -- Present in N_Aspect_Specification nodes. Points to the corresponding
600 -- pragma/attribute definition node used to process the aspect.
602 -- Assignment_OK (Flag15-Sem)
603 -- This flag is set in a subexpression node for an object, indicating
604 -- that the associated object can be modified, even if this would not
605 -- normally be permissible (either by direct assignment, or by being
606 -- passed as an out or in-out parameter). This is used by the expander
607 -- for a number of purposes, including initialization of constants and
608 -- limited type objects (such as tasks), setting discriminant fields,
609 -- setting tag values, etc. N_Object_Declaration nodes also have this
610 -- flag defined. Here it is used to indicate that an initialization
611 -- expression is valid, even where it would normally not be allowed
612 -- (e.g. where the type involved is limited).
614 -- Associated_Node (Node4-Sem)
615 -- Present in nodes that can denote an entity: identifiers, character
616 -- literals, operator symbols, expanded names, operator nodes, and
617 -- attribute reference nodes (all these nodes have an Entity field).
618 -- This field is also present in N_Aggregate, N_Selected_Component, and
619 -- N_Extension_Aggregate nodes. This field is used in generic processing
620 -- to create links between the generic template and the generic copy.
621 -- See Sem_Ch12.Get_Associated_Node for full details. Note that this
622 -- field overlaps Entity, which is fine, since, as explained in Sem_Ch12,
623 -- the normal function of Entity is not required at the point where the
624 -- Associated_Node is set. Note also, that in generic templates, this
625 -- means that the Entity field does not necessarily point to an Entity.
626 -- Since the back end is expected to ignore generic templates, this is
629 -- At_End_Proc (Node1)
630 -- This field is present in an N_Handled_Sequence_Of_Statements node.
631 -- It contains an identifier reference for the cleanup procedure to be
632 -- called. See description of this node for further details.
634 -- Backwards_OK (Flag6-Sem)
635 -- A flag present in the N_Assignment_Statement node. It is used only
636 -- if the type being assigned is an array type, and is set if analysis
637 -- determines that it is definitely safe to do the copy backwards, i.e.
638 -- starting at the highest addressed element. This is the case if either
639 -- the operands do not overlap, or they may overlap, but if they do,
640 -- then the left operand is at a higher address than the right operand.
642 -- Note: If neither of the flags Forwards_OK or Backwards_OK is set, it
643 -- means that the front end could not determine that either direction is
644 -- definitely safe, and a runtime check may be required if the backend
645 -- cannot figure it out. If both flags Forwards_OK and Backwards_OK are
646 -- set, it means that the front end can assure no overlap of operands.
648 -- Body_To_Inline (Node3-Sem)
649 -- present in subprogram declarations. Denotes analyzed but unexpanded
650 -- body of subprogram, to be used when inlining calls. Present when the
651 -- subprogram has an Inline pragma and inlining is enabled. If the
652 -- declaration is completed by a renaming_as_body, and the renamed en-
653 -- tity is a subprogram, the Body_To_Inline is the name of that entity,
654 -- which is used directly in later calls to the original subprogram.
656 -- Body_Required (Flag13-Sem)
657 -- A flag that appears in the N_Compilation_Unit node indicating that
658 -- the corresponding unit requires a body. For the package case, this
659 -- indicates that a completion is required. In Ada 95, if the flag is not
660 -- set for the package case, then a body may not be present. In Ada 83,
661 -- if the flag is not set for the package case, then body is optional.
662 -- For a subprogram declaration, the flag is set except in the case where
663 -- a pragma Import or Interface applies, in which case no body is
664 -- permitted (in Ada 83 or Ada 95).
666 -- By_Ref (Flag5-Sem)
667 -- Present in N_Simple_Return_Statement and N_Extended_Return_Statement,
668 -- this flag is set when the returned expression is already allocated on
669 -- the secondary stack and thus the result is passed by reference rather
670 -- than copied another time.
672 -- Check_Address_Alignment (Flag11-Sem)
673 -- A flag present in N_Attribute_Definition clause for a 'Address
674 -- attribute definition. This flag is set if a dynamic check should be
675 -- generated at the freeze point for the entity to which this address
676 -- clause applies. The reason that we need this flag is that we want to
677 -- check for range checks being suppressed at the point where the
678 -- attribute definition clause is given, rather than testing this at the
681 -- Coextensions (Elist4-Sem)
682 -- Present in allocators nodes. Points to list of allocators for the
683 -- access discriminants of the allocated object.
685 -- Comes_From_Extended_Return_Statement (Flag18-Sem)
686 -- Present in N_Simple_Return_Statement nodes. True if this node was
687 -- constructed as part of the N_Extended_Return_Statement expansion.
689 -- Compile_Time_Known_Aggregate (Flag18-Sem)
690 -- Present in N_Aggregate nodes. Set for aggregates which can be fully
691 -- evaluated at compile time without raising constraint error. Such
692 -- aggregates can be passed as is to Gigi without any expansion. See
693 -- Sem_Aggr for the specific conditions under which an aggregate has this
694 -- flag set. See also the flag Static_Processing_OK.
696 -- Componentwise_Assignment (Flag14-Sem)
697 -- Present in N_Assignment_Statement nodes. Set for a record assignment
698 -- where all that needs doing is to expand it into component-by-component
699 -- assignments. This is used internally for the case of tagged types with
700 -- rep clauses, where we need to avoid recursion (we don't want to try to
701 -- generate a call to the primitive operation, because this is the case
702 -- where we are compiling the primitive operation). Note that when we are
703 -- expanding component assignments in this case, we never assign the _tag
704 -- field, but we recursively assign components of the parent type.
706 -- Condition_Actions (List3-Sem)
707 -- This field appears in else-if nodes and in the iteration scheme node
708 -- for while loops. This field is only used during semantic processing to
709 -- temporarily hold actions inserted into the tree. In the tree passed
710 -- to gigi, the condition actions field is always set to No_List. For
711 -- details on how this field is used, see the routine Insert_Actions in
712 -- package Exp_Util, and also the expansion routines for the relevant
715 -- Context_Pending (Flag16-Sem)
716 -- This field appears in Compilation_Unit nodes, to indicate that the
717 -- context of the unit is being compiled. Used to detect circularities
718 -- that are not otherwise detected by the loading mechanism. Such
719 -- circularities can occur in the presence of limited and non-limited
720 -- with_clauses that mention the same units.
722 -- Controlling_Argument (Node1-Sem)
723 -- This field is set in procedure and function call nodes if the call
724 -- is a dispatching call (it is Empty for a non-dispatching call). It
725 -- indicates the source of the call's controlling tag. For procedure
726 -- calls, the Controlling_Argument is one of the actuals. For function
727 -- that has a dispatching result, it is an entity in the context of the
728 -- call that can provide a tag, or else it is the tag of the root type
729 -- of the class. It can also specify a tag directly rather than being a
730 -- tagged object. The latter is needed by the implementations of AI-239
733 -- Conversion_OK (Flag14-Sem)
734 -- A flag set on type conversion nodes to indicate that the conversion
735 -- is to be considered as being valid, even though it is the case that
736 -- the conversion is not valid Ada. This is used for attributes Enum_Rep,
737 -- Fixed_Value and Integer_Value, for internal conversions done for
738 -- fixed-point operations, and for certain conversions for calls to
739 -- initialization procedures. If Conversion_OK is set, then Etype must be
740 -- set (the analyzer assumes that Etype has been set). For the case of
741 -- fixed-point operands, it also indicates that the conversion is to be
742 -- direct conversion of the underlying integer result, with no regard to
743 -- the small operand.
745 -- Corresponding_Body (Node5-Sem)
746 -- This field is set in subprogram declarations, package declarations,
747 -- entry declarations of protected types, and in generic units. It
748 -- points to the defining entity for the corresponding body (NOT the
749 -- node for the body itself).
751 -- Corresponding_Formal_Spec (Node3-Sem)
752 -- This field is set in subprogram renaming declarations, where it points
753 -- to the defining entity for a formal subprogram in the case where the
754 -- renaming corresponds to a generic formal subprogram association in an
755 -- instantiation. The field is Empty if the renaming does not correspond
756 -- to such a formal association.
758 -- Corresponding_Generic_Association (Node5-Sem)
759 -- This field is defined for object declarations and object renaming
760 -- declarations. It is set for the declarations within an instance that
761 -- map generic formals to their actuals. If set, the field points to
762 -- a generic_association which is the original parent of the expression
763 -- or name appearing in the declaration. This simplifies ASIS queries.
765 -- Corresponding_Integer_Value (Uint4-Sem)
766 -- This field is set in real literals of fixed-point types (it is not
767 -- used for floating-point types). It contains the integer value used
768 -- to represent the fixed-point value. It is also set on the universal
769 -- real literals used to represent bounds of fixed-point base types
770 -- and their first named subtypes.
772 -- Corresponding_Spec (Node5-Sem)
773 -- This field is set in subprogram, package, task, and protected body
774 -- nodes, where it points to the defining entity in the corresponding
775 -- spec. The attribute is also set in N_With_Clause nodes where it points
776 -- to the defining entity for the with'ed spec, and in a subprogram
777 -- renaming declaration when it is a Renaming_As_Body. The field is Empty
778 -- if there is no corresponding spec, as in the case of a subprogram body
779 -- that serves as its own spec.
781 -- Corresponding_Stub (Node3-Sem)
782 -- This field is present in an N_Subunit node. It holds the node in
783 -- the parent unit that is the stub declaration for the subunit. It is
784 -- set when analysis of the stub forces loading of the proper body. If
785 -- expansion of the proper body creates new declarative nodes, they are
786 -- inserted at the point of the corresponding_stub.
788 -- Dcheck_Function (Node5-Sem)
789 -- This field is present in an N_Variant node, It references the entity
790 -- for the discriminant checking function for the variant.
792 -- Debug_Statement (Node3)
793 -- This field is present in an N_Pragma node. It is used only for a Debug
794 -- pragma. The parameter is of the form of an expression, as required by
795 -- the pragma syntax, but is actually a procedure call. To simplify
796 -- semantic processing, the parser creates a copy of the argument
797 -- rearranged into a procedure call statement and places it in the
798 -- Debug_Statement field. Note that this field is considered syntactic
799 -- field, since it is created by the parser.
801 -- Default_Expression (Node5-Sem)
802 -- This field is Empty if there is no default expression. If there is a
803 -- simple default expression (one with no side effects), then this field
804 -- simply contains a copy of the Expression field (both point to the tree
805 -- for the default expression). Default_Expression is used for
806 -- conformance checking.
808 -- Discr_Check_Funcs_Built (Flag11-Sem)
809 -- This flag is present in N_Full_Type_Declaration nodes. It is set when
810 -- discriminant checking functions are constructed. The purpose is to
811 -- avoid attempting to set these functions more than once.
813 -- Do_Accessibility_Check (Flag13-Sem)
814 -- This flag is set on N_Parameter_Specification nodes to indicate
815 -- that an accessibility check is required for the parameter. It is
816 -- not yet decided who takes care of this check (TBD ???).
818 -- Do_Discriminant_Check (Flag13-Sem)
819 -- This flag is set on N_Selected_Component nodes to indicate that a
820 -- discriminant check is required using the discriminant check routine
821 -- associated with the selector. The actual check is generated by the
822 -- expander when processing selected components.
824 -- Do_Division_Check (Flag13-Sem)
825 -- This flag is set on a division operator (/ mod rem) to indicate
826 -- that a zero divide check is required. The actual check is dealt
827 -- with by the backend (all the front end does is to set the flag).
829 -- Do_Length_Check (Flag4-Sem)
830 -- This flag is set in an N_Assignment_Statement, N_Op_And, N_Op_Or,
831 -- N_Op_Xor, or N_Type_Conversion node to indicate that a length check
832 -- is required. It is not determined who deals with this flag (???).
834 -- Do_Overflow_Check (Flag17-Sem)
835 -- This flag is set on an operator where an overflow check is required on
836 -- the operation. The actual check is dealt with by the backend (all the
837 -- front end does is to set the flag). The other cases where this flag is
838 -- used is on a Type_Conversion node and for attribute reference nodes.
839 -- For a type conversion, it means that the conversion is from one base
840 -- type to another, and the value may not fit in the target base type.
841 -- See also the description of Do_Range_Check for this case. The only
842 -- attribute references which use this flag are Pred and Succ, where it
843 -- means that the result should be checked for going outside the base
844 -- range. Note that this flag is not set for modular types.
846 -- Do_Range_Check (Flag9-Sem)
847 -- This flag is set on an expression which appears in a context where a
848 -- range check is required. The target type is clear from the context.
849 -- The contexts in which this flag can appear are the following:
851 -- Right side of an assignment. In this case the target type is
852 -- taken from the left side of the assignment, which is referenced
853 -- by the Name of the N_Assignment_Statement node.
855 -- Subscript expressions in an indexed component. In this case the
856 -- target type is determined from the type of the array, which is
857 -- referenced by the Prefix of the N_Indexed_Component node.
859 -- Argument expression for a parameter, appearing either directly in
860 -- the Parameter_Associations list of a call or as the Expression of an
861 -- N_Parameter_Association node that appears in this list. In either
862 -- case, the check is against the type of the formal. Note that the
863 -- flag is relevant only in IN and IN OUT parameters, and will be
864 -- ignored for OUT parameters, where no check is required in the call,
865 -- and if a check is required on the return, it is generated explicitly
866 -- with a type conversion.
868 -- Initialization expression for the initial value in an object
869 -- declaration. In this case the Do_Range_Check flag is set on
870 -- the initialization expression, and the check is against the
871 -- range of the type of the object being declared.
873 -- The expression of a type conversion. In this case the range check is
874 -- against the target type of the conversion. See also the use of
875 -- Do_Overflow_Check on a type conversion. The distinction is that the
876 -- overflow check protects against a value that is outside the range of
877 -- the target base type, whereas a range check checks that the
878 -- resulting value (which is a value of the base type of the target
879 -- type), satisfies the range constraint of the target type.
881 -- Note: when a range check is required in contexts other than those
882 -- listed above (e.g. in a return statement), an additional type
883 -- conversion node is introduced to represent the required check.
885 -- Do_Storage_Check (Flag17-Sem)
886 -- This flag is set in an N_Allocator node to indicate that a storage
887 -- check is required for the allocation, or in an N_Subprogram_Body node
888 -- to indicate that a stack check is required in the subprogram prolog.
889 -- The N_Allocator case is handled by the routine that expands the call
890 -- to the runtime routine. The N_Subprogram_Body case is handled by the
891 -- backend, and all the semantics does is set the flag.
893 -- Do_Tag_Check (Flag13-Sem)
894 -- This flag is set on an N_Assignment_Statement, N_Function_Call,
895 -- N_Procedure_Call_Statement, N_Type_Conversion,
896 -- N_Simple_Return_Statement, or N_Extended_Return_Statement
897 -- node to indicate that the tag check can be suppressed. It is not
898 -- yet decided how this flag is used (TBD ???).
900 -- Elaborate_Present (Flag4-Sem)
901 -- This flag is set in the N_With_Clause node to indicate that pragma
902 -- Elaborate pragma appears for the with'ed units.
904 -- Elaborate_All_Desirable (Flag9-Sem)
905 -- This flag is set in the N_With_Clause mode to indicate that the static
906 -- elaboration processing has determined that an Elaborate_All pragma is
907 -- desirable for correct elaboration for this unit.
909 -- Elaborate_All_Present (Flag14-Sem)
910 -- This flag is set in the N_With_Clause node to indicate that a
911 -- pragma Elaborate_All pragma appears for the with'ed units.
913 -- Elaborate_Desirable (Flag11-Sem)
914 -- This flag is set in the N_With_Clause mode to indicate that the static
915 -- elaboration processing has determined that an Elaborate pragma is
916 -- desirable for correct elaboration for this unit.
918 -- Elaboration_Boolean (Node2-Sem)
919 -- This field is present in function and procedure specification nodes.
920 -- If set, it points to the entity for a Boolean flag that must be tested
921 -- for certain calls to check for access before elaboration. See body of
922 -- Sem_Elab for further details. This field is Empty if no elaboration
923 -- boolean is required.
925 -- Else_Actions (List3-Sem)
926 -- This field is present in conditional expression nodes. During code
927 -- expansion we use the Insert_Actions procedure (in Exp_Util) to insert
928 -- actions at an appropriate place in the tree to get elaborated at the
929 -- right time. For conditional expressions, we have to be sure that the
930 -- actions for the Else branch are only elaborated if the condition is
931 -- False. The Else_Actions field is used as a temporary parking place for
932 -- these actions. The final tree is always rewritten to eliminate the
933 -- need for this field, so in the tree passed to Gigi, this field is
934 -- always set to No_List.
936 -- Enclosing_Variant (Node2-Sem)
937 -- This field is present in the N_Variant node and identifies the Node_Id
938 -- corresponding to the immediately enclosing variant when the variant is
939 -- nested, and N_Empty otherwise. Set during semantic processing of the
940 -- variant part of a record type.
942 -- Entity (Node4-Sem)
943 -- Appears in all direct names (identifiers, character literals, and
944 -- operator symbols), as well as expanded names, and attributes that
945 -- denote entities, such as 'Class. Points to entity for corresponding
946 -- defining occurrence. Set after name resolution. For identifiers in a
947 -- WITH list, the corresponding defining occurrence is in a separately
948 -- compiled file, and Entity must be set by the library Load procedure.
950 -- Note: During name resolution, the value in Entity may be temporarily
951 -- incorrect (e.g. during overload resolution, Entity is initially set to
952 -- the first possible correct interpretation, and then later modified if
953 -- necessary to contain the correct value after resolution).
955 -- Note: This field overlaps Associated_Node, which is used during
956 -- generic processing (see Sem_Ch12 for details). Note also that in
957 -- generic templates, this means that the Entity field does not always
958 -- point to an Entity. Since the back end is expected to ignore generic
959 -- templates, this is harmless.
961 -- Note: This field also appears in N_Attribute_Definition_Clause nodes.
962 -- It is used only for stream attributes definition clauses. In this
963 -- case, it denotes a (possibly dummy) subprogram entity that is declared
964 -- conceptually at the point of the clause. Thus the visibility of the
965 -- attribute definition clause (in the sense of 8.3(23) as amended by
966 -- AI-195) can be checked by testing the visibility of that subprogram.
968 -- Note: Normally the Entity field of an identifier points to the entity
969 -- for the corresponding defining identifier, and hence the Chars field
970 -- of an identifier will match the Chars field of the entity. However,
971 -- there is no requirement that these match, and there are obscure cases
972 -- of generated code where they do not match.
974 -- Entity_Or_Associated_Node (Node4-Sem)
975 -- A synonym for both Entity and Associated_Node. Used by convention in
976 -- the code when referencing this field in cases where it is not known
977 -- whether the field contains an Entity or an Associated_Node.
980 -- Appears in all expression nodes, all direct names, and all entities.
981 -- Points to the entity for the related type. Set after type resolution.
982 -- Normally this is the actual subtype of the expression. However, in
983 -- certain contexts such as the right side of an assignment, subscripts,
984 -- arguments to calls, returned value in a function, initial value etc.
985 -- it is the desired target type. In the event that this is different
986 -- from the actual type, the Do_Range_Check flag will be set if a range
987 -- check is required. Note: if the Is_Overloaded flag is set, then Etype
988 -- points to an essentially arbitrary choice from the possible set of
991 -- Exception_Junk (Flag8-Sem)
992 -- This flag is set in a various nodes appearing in a statement sequence
993 -- to indicate that the corresponding node is an artifact of the
994 -- generated code for exception handling, and should be ignored when
995 -- analyzing the control flow of the relevant sequence of statements
996 -- (e.g. to check that it does not end with a bad return statement).
998 -- Exception_Label (Node5-Sem)
999 -- Appears in N_Push_xxx_Label nodes. Points to the entity of the label
1000 -- to be used for transforming the corresponding exception into a goto,
1001 -- or contains Empty, if this exception is not to be transformed. Also
1002 -- appears in N_Exception_Handler nodes, where, if set, it indicates
1003 -- that there may be a local raise for the handler, so that expansion
1004 -- to allow a goto is required (and this field contains the label for
1005 -- this goto). See Exp_Ch11.Expand_Local_Exception_Handlers for details.
1007 -- Expansion_Delayed (Flag11-Sem)
1008 -- Set on aggregates and extension aggregates that need a top-down rather
1009 -- than bottom-up expansion. Typically aggregate expansion happens bottom
1010 -- up. For nested aggregates the expansion is delayed until the enclosing
1011 -- aggregate itself is expanded, e.g. in the context of a declaration. To
1012 -- delay it we set this flag. This is done to avoid creating a temporary
1013 -- for each level of a nested aggregates, and also to prevent the
1014 -- premature generation of constraint checks. This is also a requirement
1015 -- if we want to generate the proper attachment to the internal
1016 -- finalization lists (for record with controlled components). Top down
1017 -- expansion of aggregates is also used for in-place array aggregate
1018 -- assignment or initialization. When the full context is known, the
1019 -- target of the assignment or initialization is used to generate the
1020 -- left-hand side of individual assignment to each sub-component.
1022 -- First_Inlined_Subprogram (Node3-Sem)
1023 -- Present in the N_Compilation_Unit node for the main program. Points
1024 -- to a chain of entities for subprograms that are to be inlined. The
1025 -- Next_Inlined_Subprogram field of these entities is used as a link
1026 -- pointer with Empty marking the end of the list. This field is Empty
1027 -- if there are no inlined subprograms or inlining is not active.
1029 -- First_Named_Actual (Node4-Sem)
1030 -- Present in procedure call statement and function call nodes, and also
1031 -- in Intrinsic nodes. Set during semantic analysis to point to the first
1032 -- named parameter where parameters are ordered by declaration order (as
1033 -- opposed to the actual order in the call which may be different due to
1034 -- named associations). Note: this field points to the explicit actual
1035 -- parameter itself, not the N_Parameter_Association node (its parent).
1037 -- First_Real_Statement (Node2-Sem)
1038 -- Present in N_Handled_Sequence_Of_Statements node. Normally set to
1039 -- Empty. Used only when declarations are moved into the statement part
1040 -- of a construct as a result of wrapping an AT END handler that is
1041 -- required to cover the declarations. In this case, this field is used
1042 -- to remember the location in the statements list of the first real
1043 -- statement, i.e. the statement that used to be first in the statement
1044 -- list before the declarations were prepended.
1046 -- First_Subtype_Link (Node5-Sem)
1047 -- Present in N_Freeze_Entity node for an anonymous base type that is
1048 -- implicitly created by the declaration of a first subtype. It points
1049 -- to the entity for the first subtype.
1051 -- Float_Truncate (Flag11-Sem)
1052 -- A flag present in type conversion nodes. This is used for float to
1053 -- integer conversions where truncation is required rather than rounding.
1054 -- Note that Gigi does not handle type conversions from real to integer
1055 -- with rounding (see Expand_N_Type_Conversion).
1057 -- Forwards_OK (Flag5-Sem)
1058 -- A flag present in the N_Assignment_Statement node. It is used only
1059 -- if the type being assigned is an array type, and is set if analysis
1060 -- determines that it is definitely safe to do the copy forwards, i.e.
1061 -- starting at the lowest addressed element. This is the case if either
1062 -- the operands do not overlap, or they may overlap, but if they do,
1063 -- then the left operand is at a lower address than the right operand.
1065 -- Note: If neither of the flags Forwards_OK or Backwards_OK is set, it
1066 -- means that the front end could not determine that either direction is
1067 -- definitely safe, and a runtime check may be required if the backend
1068 -- cannot figure it out. If both flags Forwards_OK and Backwards_OK are
1069 -- set, it means that the front end can assure no overlap of operands.
1071 -- From_Aspect_Specification (Flag13-Sem)
1072 -- Processing of aspect specifications typically results in insertion in
1073 -- the tree of corresponding pragma or attribute definition clause nodes.
1074 -- These generated nodes have the From_Aspect_Specification flag set to
1075 -- indicate that they came from aspect specifications originally.
1077 -- From_At_End (Flag4-Sem)
1078 -- This flag is set on an N_Raise_Statement node if it corresponds to
1079 -- the reraise statement generated as the last statement of an AT END
1080 -- handler when SJLJ exception handling is active. It is used to stop
1081 -- a bogus violation of restriction (No_Exception_Propagation), bogus
1082 -- because if the restriction is set, the reraise is not generated.
1084 -- From_At_Mod (Flag4-Sem)
1085 -- This flag is set on the attribute definition clause node that is
1086 -- generated by a transformation of an at mod phrase in a record
1087 -- representation clause. This is used to give slightly different (Ada 83
1088 -- compatible) semantics to such a clause, namely it is used to specify a
1089 -- minimum acceptable alignment for the base type and all subtypes. In
1090 -- Ada 95 terms, the actual alignment of the base type and all subtypes
1091 -- must be a multiple of the given value, and the representation clause
1092 -- is considered to be type specific instead of subtype specific.
1094 -- From_Default (Flag6-Sem)
1095 -- This flag is set on the subprogram renaming declaration created in an
1096 -- instance for a formal subprogram, when the formal is declared with a
1097 -- box, and there is no explicit actual. If the flag is present, the
1098 -- declaration is treated as an implicit reference to the formal in the
1101 -- Generic_Parent (Node5-Sem)
1102 -- Generic_Parent is defined on declaration nodes that are instances. The
1103 -- value of Generic_Parent is the generic entity from which the instance
1104 -- is obtained. Generic_Parent is also defined for the renaming
1105 -- declarations and object declarations created for the actuals in an
1106 -- instantiation. The generic parent of such a declaration is the
1107 -- corresponding generic association in the Instantiation node.
1109 -- Generic_Parent_Type (Node4-Sem)
1110 -- Generic_Parent_Type is defined on Subtype_Declaration nodes for the
1111 -- actuals of formal private and derived types. Within the instance, the
1112 -- operations on the actual are those inherited from the parent. For a
1113 -- formal private type, the parent type is the generic type itself. The
1114 -- Generic_Parent_Type is also used in an instance to determine whether a
1115 -- private operation overrides an inherited one.
1117 -- Handler_List_Entry (Node2-Sem)
1118 -- This field is present in N_Object_Declaration nodes. It is set only
1119 -- for the Handler_Record entry generated for an exception in zero cost
1120 -- exception handling mode. It references the corresponding item in the
1121 -- handler list, and is used to delete this entry if the corresponding
1122 -- handler is deleted during optimization. For further details on why
1123 -- this is required, see Exp_Ch11.Remove_Handler_Entries.
1125 -- Has_No_Elaboration_Code (Flag17-Sem)
1126 -- A flag that appears in the N_Compilation_Unit node to indicate whether
1127 -- or not elaboration code is present for this unit. It is initially set
1128 -- true for subprogram specs and bodies and for all generic units and
1129 -- false for non-generic package specs and bodies. Gigi may set the flag
1130 -- in the non-generic package case if it determines that no elaboration
1131 -- code is generated. Note that this flag is not related to the
1132 -- Is_Preelaborated status, there can be preelaborated packages that
1133 -- generate elaboration code, and non-preelaborated packages which do
1134 -- not generate elaboration code.
1136 -- Has_Priority_Pragma (Flag6-Sem)
1137 -- A flag present in N_Subprogram_Body, N_Task_Definition and
1138 -- N_Protected_Definition nodes to flag the presence of either a Priority
1139 -- or Interrupt_Priority pragma in the declaration sequence (public or
1140 -- private in the task and protected cases)
1142 -- Has_Private_View (Flag11-Sem)
1143 -- A flag present in generic nodes that have an entity, to indicate that
1144 -- the node has a private type. Used to exchange private and full
1145 -- declarations if the visibility at instantiation is different from the
1146 -- visibility at generic definition.
1148 -- Has_Relative_Deadline_Pragma (Flag9-Sem)
1149 -- A flag present in N_Subprogram_Body and N_Task_Definition nodes to
1150 -- flag the presence of a pragma Relative_Deadline.
1152 -- Has_Self_Reference (Flag13-Sem)
1153 -- Present in N_Aggregate and N_Extension_Aggregate. Indicates that one
1154 -- of the expressions contains an access attribute reference to the
1155 -- enclosing type. Such a self-reference can only appear in default-
1156 -- initialized aggregate for a record type.
1158 -- Has_Storage_Size_Pragma (Flag5-Sem)
1159 -- A flag present in an N_Task_Definition node to flag the presence of a
1160 -- Storage_Size pragma.
1162 -- Has_Task_Info_Pragma (Flag7-Sem)
1163 -- A flag present in an N_Task_Definition node to flag the presence of a
1164 -- Task_Info pragma. Used to detect duplicate pragmas.
1166 -- Has_Task_Name_Pragma (Flag8-Sem)
1167 -- A flag present in N_Task_Definition nodes to flag the presence of a
1168 -- Task_Name pragma in the declaration sequence for the task.
1170 -- Has_Wide_Character (Flag11-Sem)
1171 -- Present in string literals, set if any wide character (i.e. character
1172 -- code outside the Character range but within Wide_Character range)
1173 -- appears in the string. Used to implement pragma preference rules.
1175 -- Has_Wide_Wide_Character (Flag13-Sem)
1176 -- Present in string literals, set if any wide character (i.e. character
1177 -- code outside the Wide_Character range) appears in the string. Used to
1178 -- implement pragma preference rules.
1180 -- Hidden_By_Use_Clause (Elist4-Sem)
1181 -- An entity list present in use clauses that appear within
1182 -- instantiations. For the resolution of local entities, entities
1183 -- introduced by these use clauses have priority over global ones, and
1184 -- outer entities must be explicitly hidden/restored on exit.
1186 -- Implicit_With (Flag16-Sem)
1187 -- This flag is set in the N_With_Clause node that is implicitly
1188 -- generated for runtime units that are loaded by the expander, and also
1189 -- for package System, if it is loaded implicitly by a use of the
1190 -- 'Address or 'Tag attribute. ???There are other implicit with clauses
1193 -- Import_Interface_Present (Flag16-Sem)
1194 -- This flag is set in an Interface or Import pragma if a matching
1195 -- pragma of the other kind is also present. This is used to avoid
1196 -- generating some unwanted error messages.
1198 -- Includes_Infinities (Flag11-Sem)
1199 -- This flag is present in N_Range nodes. It is set for the range of
1200 -- unconstrained float types defined in Standard, which include not only
1201 -- the given range of values, but also legitimately can include infinite
1202 -- values. This flag is false for any float type for which an explicit
1203 -- range is given by the programmer, even if that range is identical to
1204 -- the range for Float.
1206 -- Inherited_Discriminant (Flag13-Sem)
1207 -- This flag is present in N_Component_Association nodes. It indicates
1208 -- that a given component association in an extension aggregate is the
1209 -- value obtained from a constraint on an ancestor. Used to prevent
1210 -- double expansion when the aggregate has expansion delayed.
1212 -- Instance_Spec (Node5-Sem)
1213 -- This field is present in generic instantiation nodes, and also in
1214 -- formal package declaration nodes (formal package declarations are
1215 -- treated in a manner very similar to package instantiations). It points
1216 -- to the node for the spec of the instance, inserted as part of the
1217 -- semantic processing for instantiations in Sem_Ch12.
1219 -- Is_Accessibility_Actual (Flag12-Sem)
1220 -- Present in N_Parameter_Association nodes. True if the parameter is
1221 -- an extra actual that carries the accessibility level of the actual
1222 -- for an access parameter, in a function that dispatches on result and
1223 -- is called in a dispatching context. Used to prevent a formal/actual
1224 -- mismatch when the call is rewritten as a dispatching call.
1226 -- Is_Asynchronous_Call_Block (Flag7-Sem)
1227 -- A flag set in a Block_Statement node to indicate that it is the
1228 -- expansion of an asynchronous entry call. Such a block needs cleanup
1229 -- handler to assure that the call is cancelled.
1231 -- Is_Component_Left_Opnd (Flag13-Sem)
1232 -- Is_Component_Right_Opnd (Flag14-Sem)
1233 -- Present in concatenation nodes, to indicate that the corresponding
1234 -- operand is of the component type of the result. Used in resolving
1235 -- concatenation nodes in instances.
1237 -- Is_Delayed_Aspect (Flag14-Sem)
1238 -- Present in N_Pragma and N_Attribute_Definition_Clause nodes which
1239 -- come from aspect specifications, where the evaluation of the aspect
1240 -- must be delayed to the freeze point.
1242 -- Is_Controlling_Actual (Flag16-Sem)
1243 -- This flag is set on in an expression that is a controlling argument in
1244 -- a dispatching call. It is off in all other cases. See Sem_Disp for
1245 -- details of its use.
1247 -- Is_Dynamic_Coextension (Flag18-Sem)
1248 -- Present in allocator nodes, to indicate that this is an allocator
1249 -- for an access discriminant of a dynamically allocated object. The
1250 -- coextension must be deallocated and finalized at the same time as
1251 -- the enclosing object.
1253 -- Is_Entry_Barrier_Function (Flag8-Sem)
1254 -- This flag is set in an N_Subprogram_Body node which is the expansion
1255 -- of an entry barrier from a protected entry body. It is used for the
1256 -- circuitry checking for incorrect use of Current_Task.
1258 -- Is_Expanded_Build_In_Place_Call (Flag11-Sem)
1259 -- This flag is set in an N_Function_Call node to indicate that the extra
1260 -- actuals to support a build-in-place style of call have been added to
1263 -- Is_In_Discriminant_Check (Flag11-Sem)
1264 -- This flag is present in a selected component, and is used to indicate
1265 -- that the reference occurs within a discriminant check. The
1266 -- significance is that optimizations based on assuming that the
1267 -- discriminant check has a correct value cannot be performed in this
1268 -- case (or the discriminant check may be optimized away!)
1270 -- Is_Machine_Number (Flag11-Sem)
1271 -- This flag is set in an N_Real_Literal node to indicate that the value
1272 -- is a machine number. This avoids some unnecessary cases of converting
1273 -- real literals to machine numbers.
1275 -- Is_Null_Loop (Flag16-Sem)
1276 -- This flag is set in an N_Loop_Statement node if the corresponding loop
1277 -- can be determined to be null at compile time. This is used to remove
1278 -- the loop entirely at expansion time.
1280 -- Is_Overloaded (Flag5-Sem)
1281 -- A flag present in all expression nodes. Used temporarily during
1282 -- overloading determination. The setting of this flag is not relevant
1283 -- once overloading analysis is complete.
1285 -- Is_Power_Of_2_For_Shift (Flag13-Sem)
1286 -- A flag present only in N_Op_Expon nodes. It is set when the
1287 -- exponentiation is of the form 2 ** N, where the type of N is an
1288 -- unsigned integral subtype whose size does not exceed the size of
1289 -- Standard_Integer (i.e. a type that can be safely converted to
1290 -- Natural), and the exponentiation appears as the right operand of an
1291 -- integer multiplication or an integer division where the dividend is
1292 -- unsigned. It is also required that overflow checking is off for both
1293 -- the exponentiation and the multiply/divide node. If this set of
1294 -- conditions holds, and the flag is set, then the division or
1295 -- multiplication can be (and is) converted to a shift.
1297 -- Is_Protected_Subprogram_Body (Flag7-Sem)
1298 -- A flag set in a Subprogram_Body block to indicate that it is the
1299 -- implementation of a protected subprogram. Such a body needs cleanup
1300 -- handler to make sure that the associated protected object is unlocked
1301 -- when the subprogram completes.
1303 -- Is_Static_Coextension (Flag14-Sem)
1304 -- Present in N_Allocator nodes. Set if the allocator is a coextension
1305 -- of an object allocated on the stack rather than the heap.
1307 -- Is_Static_Expression (Flag6-Sem)
1308 -- Indicates that an expression is a static expression (RM 4.9). See spec
1309 -- of package Sem_Eval for full details on the use of this flag.
1311 -- Is_Subprogram_Descriptor (Flag16-Sem)
1312 -- Present in N_Object_Declaration, and set only for the object
1313 -- declaration generated for a subprogram descriptor in fast exception
1314 -- mode. See Exp_Ch11 for details of use.
1316 -- Is_Task_Allocation_Block (Flag6-Sem)
1317 -- A flag set in a Block_Statement node to indicate that it is the
1318 -- expansion of a task allocator, or the allocator of an object
1319 -- containing tasks. Such a block requires a cleanup handler to call
1320 -- Expunge_Unactivated_Tasks to complete any tasks that have been
1321 -- allocated but not activated when the allocator completes abnormally.
1323 -- Is_Task_Master (Flag5-Sem)
1324 -- A flag set in a Subprogram_Body, Block_Statement or Task_Body node to
1325 -- indicate that the construct is a task master (i.e. has declared tasks
1326 -- or declares an access to a task type).
1328 -- Itype (Node1-Sem)
1329 -- Used in N_Itype_Reference node to reference an itype for which it is
1330 -- important to ensure that it is defined. See description of this node
1331 -- for further details.
1333 -- Kill_Range_Check (Flag11-Sem)
1334 -- Used in an N_Unchecked_Type_Conversion node to indicate that the
1335 -- result should not be subjected to range checks. This is used for the
1336 -- implementation of Normalize_Scalars.
1338 -- Label_Construct (Node2-Sem)
1339 -- Used in an N_Implicit_Label_Declaration node. Refers to an N_Label,
1340 -- N_Block_Statement or N_Loop_Statement node to which the label
1341 -- declaration applies. This is not currently used in the compiler
1342 -- itself, but it is useful in the implementation of ASIS queries.
1343 -- This field is left empty for the special labels generated as part
1344 -- of expanding raise statements with a local exception handler.
1346 -- Library_Unit (Node4-Sem)
1347 -- In a stub node, Library_Unit points to the compilation unit node of
1348 -- the corresponding subunit.
1350 -- In a with clause node, Library_Unit points to the spec of the with'ed
1353 -- In a compilation unit node, the usage depends on the unit type:
1355 -- For a library unit body, Library_Unit points to the compilation unit
1356 -- node of the corresponding spec, unless it's a subprogram body with
1357 -- Acts_As_Spec set, in which case it points to itself.
1359 -- For a spec, Library_Unit points to the compilation unit node of the
1360 -- corresponding body, if present. The body will be present if the spec
1361 -- is or contains generics that we needed to instantiate. Similarly, the
1362 -- body will be present if we needed it for inlining purposes. Thus, if
1363 -- we have a spec/body pair, both of which are present, they point to
1364 -- each other via Library_Unit.
1366 -- For a subunit, Library_Unit points to the compilation unit node of
1369 -- Note that this field is not used to hold the parent pointer for child
1370 -- unit (which might in any case need to use it for some other purpose as
1371 -- described above). Instead for a child unit, implicit with's are
1372 -- generated for all parents.
1374 -- Local_Raise_Statements (Elist1)
1375 -- This field is present in exception handler nodes. It is set to
1376 -- No_Elist in the normal case. If there is at least one raise statement
1377 -- which can potentially be handled as a local raise, then this field
1378 -- points to a list of raise nodes, which are calls to a routine to raise
1379 -- an exception. These are raise nodes which can be optimized into gotos
1380 -- if the handler turns out to meet the conditions which permit this
1381 -- transformation. Note that this does NOT include instances of the
1382 -- N_Raise_xxx_Error nodes since the transformation of these nodes is
1383 -- handled by the back end (using the N_Push/N_Pop mechanism).
1385 -- Loop_Actions (List2-Sem)
1386 -- A list present in Component_Association nodes in array aggregates.
1387 -- Used to collect actions that must be executed within the loop because
1388 -- they may need to be evaluated anew each time through.
1390 -- Limited_View_Installed (Flag18-Sem)
1391 -- Present in With_Clauses and in package specifications. If set on
1392 -- with_clause, it indicates that this clause has created the current
1393 -- limited view of the designated package. On a package specification, it
1394 -- indicates that the limited view has already been created because the
1395 -- package is mentioned in a limited_with_clause in the closure of the
1396 -- unit being compiled.
1398 -- Local_Raise_Not_OK (Flag7-Sem)
1399 -- Present in N_Exception_Handler nodes. Set if the handler contains
1400 -- a construct (reraise statement, or call to subprogram in package
1401 -- GNAT.Current_Exception) that makes the handler unsuitable as a target
1402 -- for a local raise (one that could otherwise be converted to a goto).
1404 -- Must_Be_Byte_Aligned (Flag14-Sem)
1405 -- This flag is present in N_Attribute_Reference nodes. It can be set
1406 -- only for the Address and Unrestricted_Access attributes. If set it
1407 -- means that the object for which the address/access is given must be on
1408 -- a byte (more accurately a storage unit) boundary. If necessary, a copy
1409 -- of the object is to be made before taking the address (this copy is in
1410 -- the current scope on the stack frame). This is used for certain cases
1411 -- of code generated by the expander that passes parameters by address.
1413 -- The reason the copy is not made by the front end is that the back end
1414 -- has more information about type layout and may be able to (but is not
1415 -- guaranteed to) prevent making unnecessary copies.
1417 -- Must_Not_Freeze (Flag8-Sem)
1418 -- A flag present in all expression nodes. Normally expressions cause
1419 -- freezing as described in the RM. If this flag is set, then this is
1420 -- inhibited. This is used by the analyzer and expander to label nodes
1421 -- that are created by semantic analysis or expansion and which must not
1422 -- cause freezing even though they normally would. This flag is also
1423 -- present in an N_Subtype_Indication node, since we also use these in
1424 -- calls to Freeze_Expression.
1426 -- Next_Entity (Node2-Sem)
1427 -- Present in defining identifiers, defining character literals and
1428 -- defining operator symbols (i.e. in all entities). The entities of a
1429 -- scope are chained, and this field is used as the forward pointer for
1430 -- this list. See Einfo for further details.
1432 -- Next_Exit_Statement (Node3-Sem)
1433 -- Present in N_Exit_Statement nodes. The exit statements for a loop are
1434 -- chained (in reverse order of appearence) from the First_Exit_Statement
1435 -- field of the E_Loop entity for the loop. Next_Exit_Statement points to
1436 -- the next entry on this chain (Empty = end of list).
1438 -- Next_Implicit_With (Node3-Sem)
1439 -- Present in N_With_Clause. Part of a chain of with_clauses generated
1440 -- in rtsfind to indicate implicit dependencies on predefined units. Used
1441 -- to prevent multiple with_clauses for the same unit in a given context.
1442 -- A postorder traversal of the tree whose nodes are units and whose
1443 -- links are with_clauses defines the order in which Inspector must
1444 -- examine a compiled unit and its full context. This ordering ensures
1445 -- that any subprogram call is examined after the subprogram declartion
1448 -- Next_Named_Actual (Node4-Sem)
1449 -- Present in parameter association node. Set during semantic analysis to
1450 -- point to the next named parameter, where parameters are ordered by
1451 -- declaration order (as opposed to the actual order in the call, which
1452 -- may be different due to named associations). Not that this field
1453 -- points to the explicit actual parameter itself, not to the
1454 -- N_Parameter_Association node (its parent).
1456 -- Next_Pragma (Node1-Sem)
1457 -- Present in N_Pragma nodes. Used to create a linked list of pragma
1458 -- nodes. Currently used for two purposes:
1460 -- Create a list of linked Check_Policy pragmas. The head of this list
1461 -- is stored in Opt.Check_Policy_List (which has further details).
1463 -- Used by processing for Pre/Postcondition pragmas to store a list of
1464 -- pragmas associated with the spec of a subprogram (see Sem_Prag for
1467 -- Next_Rep_Item (Node5-Sem)
1468 -- Present in pragma nodes, attribute definition nodes, enumeration rep
1469 -- clauses, record rep clauses, aspect specification nodes. Used to link
1470 -- representation items that apply to an entity. See full description of
1471 -- First_Rep_Item field in Einfo for further details.
1473 -- Next_Use_Clause (Node3-Sem)
1474 -- While use clauses are active during semantic processing, they are
1475 -- chained from the scope stack entry, using Next_Use_Clause as a link
1476 -- pointer, with Empty marking the end of the list. The head pointer is
1477 -- in the scope stack entry (First_Use_Clause). At the end of semantic
1478 -- processing (i.e. when Gigi sees the tree, the contents of this field
1479 -- is undefined and should not be read).
1481 -- No_Ctrl_Actions (Flag7-Sem)
1482 -- Present in N_Assignment_Statement to indicate that no finalize nor
1483 -- adjust should take place on this assignment even though the rhs is
1484 -- controlled. This is used in init procs and aggregate expansions where
1485 -- the generated assignments are more initialisations than real
1488 -- No_Elaboration_Check (Flag14-Sem)
1489 -- Present in N_Function_Call and N_Procedure_Call_Statement. Indicates
1490 -- that no elaboration check is needed on the call, because it appears in
1491 -- the context of a local Suppress pragma. This is used on calls within
1492 -- task bodies, where the actual elaboration checks are applied after
1493 -- analysis, when the local scope stack is not present.
1495 -- No_Entities_Ref_In_Spec (Flag8-Sem)
1496 -- Present in N_With_Clause nodes. Set if the with clause is on the
1497 -- package or subprogram spec where the main unit is the corresponding
1498 -- body, and no entities of the with'ed unit are referenced by the spec
1499 -- (an entity may still be referenced in the body, so this flag is used
1500 -- to generate the proper message (see Sem_Util.Check_Unused_Withs for
1503 -- No_Initialization (Flag13-Sem)
1504 -- Present in N_Object_Declaration and N_Allocator to indicate that the
1505 -- object must not be initialized (by Initialize or call to an init
1506 -- proc). This is needed for controlled aggregates. When the Object
1507 -- declaration has an expression, this flag means that this expression
1508 -- should not be taken into account (needed for in place initialization
1509 -- with aggregates).
1511 -- No_Truncation (Flag17-Sem)
1512 -- Present in N_Unchecked_Type_Conversion node. This flag has an effect
1513 -- only if the RM_Size of the source is greater than the RM_Size of the
1514 -- target for scalar operands. Normally in such a case we truncate some
1515 -- higher order bits of the source, and then sign/zero extend the result
1516 -- to form the output value. But if this flag is set, then we do not do
1517 -- any truncation, so for example, if an 8 bit input is converted to 5
1518 -- bit result which is in fact stored in 8 bits, then the high order
1519 -- three bits of the target result will be copied from the source. This
1520 -- is used for properly setting out of range values for use by pragmas
1521 -- Initialize_Scalars and Normalize_Scalars.
1523 -- Original_Discriminant (Node2-Sem)
1524 -- Present in identifiers. Used in references to discriminants that
1525 -- appear in generic units. Because the names of the discriminants may be
1526 -- different in an instance, we use this field to recover the position of
1527 -- the discriminant in the original type, and replace it with the
1528 -- discriminant at the same position in the instantiated type.
1530 -- Original_Entity (Node2-Sem)
1531 -- Present in numeric literals. Used to denote the named number that has
1532 -- been constant-folded into the given literal. If literal is from
1533 -- source, or the result of some other constant-folding operation, then
1534 -- Original_Entity is empty. This field is needed to handle properly
1535 -- named numbers in generic units, where the Associated_Node field

1539 -- Others_Discrete_Choices (List1-Sem)
1540 -- When a case statement or variant is analyzed, the semantic checks
1541 -- determine the actual list of choices that correspond to an others
1542 -- choice. This list is materialized for later use by the expander and
1543 -- the Others_Discrete_Choices field of an N_Others_Choice node points to
1544 -- this materialized list of choices, which is in standard format for a
1545 -- list of discrete choices, except that of course it cannot contain an
1546 -- N_Others_Choice entry.
1548 -- Parameter_List_Truncated (Flag17-Sem)
1549 -- Present in N_Function_Call and N_Procedure_Call_Statement nodes. Set
1550 -- (for OpenVMS ports of GNAT only) if the parameter list is truncated as
1551 -- a result of a First_Optional_Parameter specification in an
1552 -- Import_Function, Import_Procedure, or Import_Valued_Procedure pragma.
1553 -- The truncation is done by the expander by removing trailing parameters
1554 -- from the argument list, in accordance with the set of rules allowing
1555 -- such parameter removal. In particular, parameters can be removed
1556 -- working from the end of the parameter list backwards up to and
1557 -- including the entry designated by First_Optional_Parameter in the
1558 -- Import pragma. Parameters can be removed if they are implicit and the
1559 -- default value is a known-at-compile-time value, including the use of
1560 -- the Null_Parameter attribute, or if explicit parameter values are
1561 -- present that match the corresponding defaults.
1563 -- Parent_Spec (Node4-Sem)
1564 -- For a library unit that is a child unit spec (package or subprogram
1565 -- declaration, generic declaration or instantiation, or library level
1566 -- rename, this field points to the compilation unit node for the parent
1567 -- package specification. This field is Empty for library bodies (the
1568 -- parent spec in this case can be found from the corresponding spec).
1570 -- Pragma_Enabled (Flag5-Sem)
1571 -- Present in N_Pragma nodes. This flag is relevant only for pragmas
1572 -- Assert, Check, Precondition, and Postcondition. It is true if the
1573 -- check corresponding to the pragma type is enabled at the point where
1574 -- the pragma appears.
1576 -- Present_Expr (Uint3-Sem)
1577 -- Present in an N_Variant node. This has a meaningful value only after
1578 -- Gigi has back annotated the tree with representation information. At
1579 -- this point, it contains a reference to a gcc expression that depends
1580 -- on the values of one or more discriminants. Give a set of discriminant
1581 -- values, this expression evaluates to False (zero) if variant is not
1582 -- present, and True (non-zero) if it is present. See unit Repinfo for
1583 -- further details on gigi back annotation. This field is used during
1584 -- ASIS processing (data decomposition annex) to determine if a field is
1587 -- Print_In_Hex (Flag13-Sem)
1588 -- Set on an N_Integer_Literal node to indicate that the value should be
1589 -- printed in hexadecimal in the sprint listing. Has no effect on
1590 -- legality or semantics of program, only on the displayed output. This
1591 -- is used to clarify output from the packed array cases.
1593 -- Procedure_To_Call (Node2-Sem)
1594 -- Present in N_Allocator, N_Free_Statement, N_Simple_Return_Statement,
1595 -- and N_Extended_Return_Statement nodes. References the entity for the
1596 -- declaration of the procedure to be called to accomplish the required
1597 -- operation (i.e. for the Allocate procedure in the case of N_Allocator
1598 -- and N_Simple_Return_Statement and N_Extended_Return_Statement (for
1599 -- allocating the return value), and for the Deallocate procedure in the
1600 -- case of N_Free_Statement.
1602 -- Raises_Constraint_Error (Flag7-Sem)
1603 -- Set on an expression whose evaluation will definitely fail constraint
1604 -- error check. In the case of static expressions, this flag must be set
1605 -- accurately (and if it is set, the expression is typically illegal
1606 -- unless it appears as a non-elaborated branch of a short-circuit form).
1607 -- For a non-static expression, this flag may be set whenever an
1608 -- expression (e.g. an aggregate) is known to raise constraint error. If
1609 -- set, the expression definitely will raise CE if elaborated at runtime.
1610 -- If not set, the expression may or may not raise CE. In other words, on
1611 -- static expressions, the flag is set accurately, on non-static
1612 -- expressions it is set conservatively.
1614 -- Redundant_Use (Flag13-Sem)
1615 -- Present in nodes that can appear as an operand in a use clause or use
1616 -- type clause (identifiers, expanded names, attribute references). Set
1617 -- to indicate that a use is redundant (and therefore need not be undone
1620 -- Renaming_Exception (Node2-Sem)
1621 -- Present in N_Exception_Declaration node. Used to point back to the
1622 -- exception renaming for an exception declared within a subprogram.
1623 -- What happens is that an exception declared in a subprogram is moved
1624 -- to the library level with a unique name, and the original exception
1625 -- becomes a renaming. This link from the library level exception to the
1626 -- renaming declaration allows registering of the proper exception name.
1628 -- Return_Statement_Entity (Node5-Sem)
1629 -- Present in N_Simple_Return_Statement and N_Extended_Return_Statement.
1630 -- Points to an E_Return_Statement representing the return statement.
1632 -- Return_Object_Declarations (List3)
1633 -- Present in N_Extended_Return_Statement.
1634 -- Points to a list initially containing a single
1635 -- N_Object_Declaration representing the return object.
1636 -- We use a list (instead of just a pointer to the object decl)
1637 -- because Analyze wants to insert extra actions on this list.
1639 -- Rounded_Result (Flag18-Sem)
1640 -- Present in N_Type_Conversion, N_Op_Divide and N_Op_Multiply nodes.
1641 -- Used in the fixed-point cases to indicate that the result must be
1642 -- rounded as a result of the use of the 'Round attribute. Also used for
1643 -- integer N_Op_Divide nodes to indicate that the result should be
1644 -- rounded to the nearest integer (breaking ties away from zero), rather
1645 -- than truncated towards zero as usual. These rounded integer operations
1646 -- are the result of expansion of rounded fixed-point divide, conversion
1647 -- and multiplication operations.
1649 -- SCIL_Entity (Node4-Sem)
1650 -- Present in SCIL nodes. Used to reference the tagged type associated
1651 -- with the SCIL node.
1653 -- SCIL_Controlling_Tag (Node5-Sem)
1654 -- Present in N_SCIL_Dispatching_Call nodes. Used to reference the
1655 -- controlling tag of a dispatching call.
1657 -- SCIL_Tag_Value (Node5-Sem)
1658 -- Present in N_SCIL_Membership_Test nodes. Used to reference the tag
1659 -- value that is being tested.
1661 -- SCIL_Target_Prim (Node2-Sem)
1662 -- Present in N_SCIL_Dispatching_Call nodes. Used to reference the tagged
1663 -- type primitive associated with the SCIL node.
1665 -- Scope (Node3-Sem)
1666 -- Present in defining identifiers, defining character literals and
1667 -- defining operator symbols (i.e. in all entities). The entities of a
1668 -- scope all use this field to reference the corresponding scope entity.
1669 -- See Einfo for further details.
1671 -- Shift_Count_OK (Flag4-Sem)
1672 -- A flag present in shift nodes to indicate that the shift count is
1673 -- known to be in range, i.e. is in the range from zero to word length
1674 -- minus one. If this flag is not set, then the shift count may be
1675 -- outside this range, i.e. larger than the word length, and the code
1676 -- must ensure that such shift counts give the appropriate result.
1678 -- Source_Type (Node1-Sem)
1679 -- Used in an N_Validate_Unchecked_Conversion node to point to the
1680 -- source type entity for the unchecked conversion instantiation
1681 -- which gigi must do size validation for.
1683 -- Static_Processing_OK (Flag4-Sem)
1684 -- Present in N_Aggregate nodes. When the Compile_Time_Known_Aggregate
1685 -- flag is set, the full value of the aggregate can be determined at
1686 -- compile time and the aggregate can be passed as is to the back-end.
1687 -- In this event it is irrelevant whether this flag is set or not.
1688 -- However, if the flag Compile_Time_Known_Aggregate is not set but
1689 -- Static_Processing_OK is set, the aggregate can (but need not) be
1690 -- converted into a compile time known aggregate by the expander. See
1691 -- Sem_Aggr for the specific conditions under which an aggregate has its
1692 -- Static_Processing_OK flag set.
1694 -- Storage_Pool (Node1-Sem)
1695 -- Present in N_Allocator, N_Free_Statement, N_Simple_Return_Statement,
1696 -- and N_Extended_Return_Statement nodes. References the entity for the
1697 -- storage pool to be used for the allocate or free call or for the
1698 -- allocation of the returned value from function. Empty indicates that
1699 -- the global default pool is to be used. Note that in the case
1700 -- of a return statement, this field is set only if the function returns
1701 -- value of a type whose size is not known at compile time on the
1704 -- Suppress_Loop_Warnings (Flag17-Sem)
1705 -- Used in N_Loop_Statement node to indicate that warnings within the
1706 -- body of the loop should be suppressed. This is set when the range
1707 -- of a FOR loop is known to be null, or is probably null (loop would
1708 -- only execute if invalid values are present).
1710 -- Target_Type (Node2-Sem)
1711 -- Used in an N_Validate_Unchecked_Conversion node to point to the target
1712 -- type entity for the unchecked conversion instantiation which gigi must
1713 -- do size validation for.
1715 -- Then_Actions (List3-Sem)
1716 -- This field is present in conditional expression nodes. During code
1717 -- expansion we use the Insert_Actions procedure (in Exp_Util) to insert
1718 -- actions at an appropriate place in the tree to get elaborated at the
1719 -- right time. For conditional expressions, we have to be sure that the
1720 -- actions for the Then branch are only elaborated if the condition is
1721 -- True. The Then_Actions field is used as a temporary parking place for
1722 -- these actions. The final tree is always rewritten to eliminate the
1723 -- need for this field, so in the tree passed to Gigi, this field is
1724 -- always set to No_List.
1726 -- Treat_Fixed_As_Integer (Flag14-Sem)
1727 -- This flag appears in operator nodes for divide, multiply, mod and rem
1728 -- on fixed-point operands. It indicates that the operands are to be
1729 -- treated as integer values, ignoring small values. This flag is only
1730 -- set as a result of expansion of fixed-point operations. Typically a
1731 -- fixed-point multiplication in the source generates subsidiary
1732 -- multiplication and division operations that work with the underlying
1733 -- integer values and have this flag set. Note that this flag is not
1734 -- needed on other arithmetic operations (add, neg, subtract etc.) since
1735 -- in these cases it is always the case that fixed is treated as integer.
1736 -- The Etype field MUST be set if this flag is set. The analyzer knows to
1737 -- leave such nodes alone, and whoever makes them must set the correct
1740 -- TSS_Elist (Elist3-Sem)
1741 -- Present in N_Freeze_Entity nodes. Holds an element list containing
1742 -- entries for each TSS (type support subprogram) associated with the
1743 -- frozen type. The elements of the list are the entities for the
1744 -- subprograms (see package Exp_TSS for further details). Set to No_Elist
1745 -- if there are no type support subprograms for the type or if the freeze
1746 -- node is not for a type.
1748 -- Unreferenced_In_Spec (Flag7-Sem)
1749 -- Present in N_With_Clause nodes. Set if the with clause is on the
1750 -- package or subprogram spec where the main unit is the corresponding
1751 -- body, and is not referenced by the spec (it may still be referenced by
1752 -- the body, so this flag is used to generate the proper message (see
1753 -- Sem_Util.Check_Unused_Withs for details)
1755 -- Was_Originally_Stub (Flag13-Sem)
1756 -- This flag is set in the node for a proper body that replaces stub.
1757 -- During the analysis procedure, stubs in some situations get rewritten
1758 -- by the corresponding bodies, and we set this flag to remember that
1759 -- this happened. Note that it is not good enough to rely on the use of
1760 -- Original_Node here because of the case of nested instantiations where
1761 -- the substituted node can be copied.
1763 -- Withed_Body (Node1-Sem)
1764 -- Present in N_With_Clause nodes. Set if the unit in whose context
1765 -- the with_clause appears instantiates a generic contained in the
1766 -- library unit of the with_clause and as a result loads its body.
1767 -- Used for a more precise unit traversal for CodePeer.
1769 -- Zero_Cost_Handling (Flag5-Sem)
1770 -- This flag is set in all handled sequence of statement and exception
1771 -- handler nodes if exceptions are to be handled using the zero-cost
1772 -- mechanism (see Ada.Exceptions and System.Exceptions in files
1773 -- a-except.ads/adb and s-except.ads for full details). What gigi needs
1774 -- to do for such a handler is simply to put the code in the handler
1775 -- somewhere. The front end has generated all necessary labels.
1777 --------------------------------------------------
1778 -- Note on Use of End_Label and End_Span Fields --
1779 --------------------------------------------------

1794 -- Entry Body end [entry_IDENTIFIER];
1796 -- If Statement end if;
1797 -- Case Statement end case;
1799 -- Record Definition end record;
1800 -- Enumeration Definition );
1802 -- The End_Label and End_Span fields are used to mark the locations of
1803 -- these lines, and also keep track of the label in the case where a label
1806 -- For the first group above, the End_Label field of the corresponding node
1807 -- is used to point to the label identifier. In the case where there is no
1808 -- label in the source, the parser supplies a dummy identifier (with
1809 -- Comes_From_Source set to False), and the Sloc of this dummy identifier
1810 -- marks the location of the token following the END token.
1812 -- For the second group, the use of End_Label is similar, but the End_Label
1813 -- is found in the N_Handled_Sequence_Of_Statements node. This is done
1814 -- simply because in some cases there is no room in the parent node.
1816 -- For the third group, there is never any label, and instead of using
1817 -- End_Label, we use the End_Span field which gives the location of the
1818 -- token following END, relative to the starting Sloc of the construct,
1819 -- i.e. add Sloc (Node) + End_Span (Node) to get the Sloc of the IF or CASE
1820 -- following the End_Label.
1822 -- The record definition case is handled specially, we treat it as though
1823 -- it required an optional label which is never present, and so the parser
1824 -- always builds a dummy identifier with Comes From Source set False. The
1825 -- reason we do this, rather than using End_Span in this case, is that we
1826 -- want to generate a cross-ref entry for the end of a record, since it
1827 -- represents a scope for name declaration purposes.
1829 -- The enumeration definition case is handled in an exactly similar manner,
1830 -- building a dummy identifier to get a cross-reference.
1832 -- Note: the reason we store the difference as a Uint, instead of storing
1833 -- the Source_Ptr value directly, is that Source_Ptr values cannot be
1834 -- distinguished from other types of values, and we count on all general
1835 -- use fields being self describing. To make things easier for clients,
1836 -- note that we provide function End_Location, and procedure
1837 -- Set_End_Location to allow access to the logical value (which is the
1838 -- Source_Ptr value for the end token).

3205 -- A'Class (X) X is the expression of a type conversion
3207 -- It would be possible for the parser to distinguish these cases
3208 -- by looking at the attribute identifier. However, that would mean
3209 -- more work in introducing new implementation defined attributes,
3210 -- and also it would mean that special processing for attributes
3211 -- would be scattered around, instead of being centralized in the
3212 -- semantic routine that handles an N_Attribute_Reference node.
3213 -- Consequently, the parser in all the above cases stores the
3214 -- expression (X in these examples) as a single element list in
3215 -- in the Expressions field of the N_Attribute_Reference node.
3217 -- Similarly, for attributes like Max which take two arguments,
3218 -- we store the two arguments as a two element list in the
3219 -- Expressions field. Of course it is clear at parse time that
3220 -- this case is really a function call with an attribute as the
3221 -- prefix, but it turns out to be convenient to handle the two
3222 -- argument case in a similar manner to the one argument case,
3223 -- and indeed in general the parser will accept any number of
3224 -- expressions in this position and store them as a list in the
3225 -- attribute reference node. This allows for future addition of
3226 -- attributes that take more than two arguments.
3228 -- Note: named associates are not permitted in function calls where
3229 -- the function is an attribute (see RM 6.4(3)) so it is legitimate
3230 -- to skip the normal subprogram argument processing.
3232 -- Note: for the attributes whose designators are technically keywords,
3233 -- i.e. digits, access, delta, range, the Attribute_Name field contains
3234 -- the corresponding name, even though no identifier is involved.
3236 -- Note: the generated code may contain stream attributes applied to
3237 -- limited types for which no stream routines exist officially. In such
3238 -- case, the result is to use the stream attribute for the underlying
3239 -- full type, or in the case of a protected type, the components
3240 -- (including any discriminants) are merely streamed in order.
3242 -- See Exp_Attr for a complete description of which attributes are
3243 -- passed onto Gigi, and which are handled entirely by the front end.
3245 -- Gigi restriction: For the Pos attribute, the prefix cannot be
3246 -- a non-standard enumeration type or a nonzero/zero semantics
3247 -- boolean type, so the value is simply the stored representation.
3249 -- Gigi requirement: For the Mechanism_Code attribute, if the prefix
3250 -- references a subprogram that is a renaming, then the front end must
3251 -- rewrite the attribute to refer directly to the renamed entity.
3253 -- Note: In generated code, the Address and Unrestricted_Access
3254 -- attributes can be applied to any expression, and the meaning is
3255 -- to create an object containing the value (the object is in the
3256 -- current stack frame), and pass the address of this value. If the

3511 -- Second, the case of (EXPRESSION) is handled specially. Ada requires
3512 -- that the parser keep track of which subexpressions are enclosed

3514 -- information is required for optimization purposes, and also for
3515 -- some semantic checks (e.g. (((1))) in a procedure spec does not
3516 -- conform with ((((1)))) in the body).
3518 -- The parentheses are recorded by keeping a Paren_Count field in every
3519 -- subexpression node (it is actually present in all nodes, but only
3520 -- used in subexpression nodes). This count records the number of
3521 -- levels of parentheses. If the number of levels in the source exceeds

3526 -- but we do not need to lose sleep over this.
3528 -- Historical note: in versions of GNAT prior to 1.75, there was a node
3529 -- type N_Parenthesized_Expression used to accurately record unlimited
3530 -- numbers of levels of parentheses. However, it turned out to be a
3531 -- real nuisance to have to take into account the possible presence of
3532 -- this node during semantic analysis, since basically parentheses have
3533 -- zero relevance to semantic analysis.
3535 -- Note: the level of parentheses always present in things like
3536 -- aggregates does not count, only the parentheses in the primary

5494 -- The N_Compilation_Unit node itself represents the above syntax.
5495 -- However, there are two additional items not reflected in the above
5496 -- syntax. First we have the global declarations that are added by the
5497 -- code generator. These are outer level declarations (so they cannot
5498 -- be represented as being inside the units). An example is the wrapper
5499 -- subprograms that are created to do ABE checking. As always a list of
5500 -- declarations can contain actions as well (i.e. statements), and such
5501 -- statements are executed as part of the elaboration of the unit. Note
5502 -- that all such declarations are elaborated before the library unit.
5504 -- Similarly, certain actions need to be elaborated at the completion
5505 -- of elaboration of the library unit (notably the statement that sets
5506 -- the Boolean flag indicating that elaboration is complete).
5508 -- The third item not reflected in the syntax is pragmas that appear
5509 -- after the compilation unit. As always pragmas are a problem since
5510 -- they are not part of the formal syntax, but can be stuck into the

6707 -- The Ada language does not permit conditional expressions, however
6708 -- this is under discussion as a possible extension by the ARG, and we
6709 -- have implemented a form of this capability in GNAT under control of

6766 -- This node is created by the analyzer/expander to handle some
6767 -- expansion cases, notably short circuit forms where there are
6768 -- actions associated with the right hand operand.
6770 -- The N_Expression_With_Actions node represents an expression with
6771 -- an associated set of actions (which are executable statements and
6772 -- declarations, as might occur in a handled statement sequence).
6774 -- The required semantics is that the set of actions is executed in
6775 -- the order in which it appears just before the expression is
6776 -- evaluated (and these actions must only be executed if the value
6777 -- of the expression is evaluated). The node is considered to be
6778 -- a subexpression, whose value is the value of the Expression after
6779 -- executing all the actions.
6781 -- Note: if the actions contain declarations, then these declarations
6782 -- maybe referenced with in the expression. It is thus appropriate for
6783 -- the back end to create a scope that encompasses the construct (any
6784 -- declarations within the actions will definitely not be referenced

6826 -- This node marks the point in a declarative part at which an entity
6827 -- declared therein becomes frozen. The expander places initialization
6828 -- procedures for types at those points. Gigi uses the freezing point
6829 -- to elaborate entities that may depend on previous private types.
6831 -- See the section in Einfo "Delayed Freezing and Elaboration" for
6832 -- a full description of the use of this node.
6834 -- The Entity field points back to the entity for the type (whose

6837 -- The Actions field contains a list of declarations and statements
6838 -- generated by the expander which are associated with the freeze
6839 -- node, and are elaborated as though the freeze node were replaced
6840 -- by this sequence of actions.
6842 -- Note: the Sloc field in the freeze node references a construct
6843 -- associated with the freezing point. This is used for posting
6844 -- messages in some error/warning situations, e.g. the case where
6845 -- a primitive operation of a tagged type is declared too late.

6866 -- Implicit Label Declaration --
6867 --------------------------------
6869 -- An implicit label declaration is created for every occurrence of a
6870 -- label on a statement or a label on a block or loop. It is chained
6871 -- in the declarations of the innermost enclosing block as specified
6872 -- in RM section 5.1 (3).
6874 -- The Defining_Identifier is the actual identifier for the statement
6875 -- identifier. Note that the occurrence of the label is a reference, NOT
6876 -- the defining occurrence. The defining occurrence occurs at the head
6877 -- of the innermost enclosing block, and is represented by this node.
6879 -- Note: from the grammar, this might better be called an implicit
6880 -- statement identifier declaration, but the term we choose seems
6881 -- friendlier, since at least informally statement identifiers are
6882 -- called labels in both cases (i.e. when used in labels, and when
6883 -- used as the identifiers of blocks and loops).
6885 -- Note: although this is logically a semantic node, since it does not
6886 -- correspond directly to a source syntax construction, these nodes are
6887 -- actually created by the parser in a post pass done just after parsing

6907 -- A typical use of this node is when an Itype is to be referenced in
6908 -- two branches of an IF statement. In this case it is important that
6909 -- the first use of the Itype not be inside the conditional, since then

6925 -- Raise_xxx_Error --
6926 ---------------------
6928 -- One of these nodes is created during semantic analysis to replace
6929 -- a node for an expression that is determined to definitely raise
6930 -- the corresponding exception.
6932 -- The N_Raise_xxx_Error node may also stand alone in place
6933 -- of a declaration or statement, in which case it simply causes
6934 -- the exception to be raised (i.e. it is equivalent to a raise
6935 -- statement that raises the corresponding exception). This use
6936 -- is distinguished by the fact that the Etype in this case is
6937 -- Standard_Void_Type, In the subexpression case, the Etype is the
6938 -- same as the type of the subexpression which it replaces.
6940 -- If Condition is empty, then the raise is unconditional. If the
6941 -- Condition field is non-empty, it is a boolean expression which
6942 -- is first evaluated, and the exception is raised only if the
6943 -- value of the expression is True. In the unconditional case, the

6945 -- error. The creation of this node will usually be accompanied by a
6946 -- message (unless it appears within the right operand of a short
6947 -- circuit form whose left argument is static and decisively

7006 -- 2. Exceptions from checks triggered by Do_xxx_Check flags
7007 -- 3. Other cases not specifically marked by the front end
7009 -- Normally all such exceptions are translated into calls to the proper
7010 -- Rcheck_xx procedure, where xx encodes both the exception to be raised
7011 -- and the exception message.
7013 -- The front end may determine that for a particular sequence of code,
7014 -- exceptions in any of these three categories for a particular builtin
7015 -- exception should result in a goto, rather than a call to Rcheck_xx.
7016 -- The exact sequence to be generated is:

7026 -- (code where transformation is expected for exception xxx)
7030 -- The use of push/pop reflects the fact that such regions can properly
