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 these places:
65 -- The documentation associated with the field (if semantic)
66 -- The documentation associated with the node
67 -- The spec of the access function
68 -- The spec of the set procedure
69 -- The entries in Is_Syntactic_Field
70 -- The pragma Inline for the access function
71 -- The pragma Inline for the set procedure
73 -- The body of the access function
74 -- The body of the set procedure
76 -- The field chosen must be consistent in all places, and, for a node that
77 -- is a subexpression, must not overlap any of the standard expression
80 -- In addition, if any of the standard expression fields is changed, then
81 -- the utility program which creates the Treeprs spec (in file treeprs.ads)
82 -- must be updated appropriately, since it special cases expression fields.
84 -- If a new tree node is added, then the following changes are made
86 -- Add it to the documentation in the appropriate place
87 -- Add its fields to this documentation section
88 -- Define it in the appropriate classification in Node_Kind
89 -- In the body (sinfo), add entries to the access functions for all
90 -- its fields (except standard expression fields) to include the new
91 -- node in the checks.
92 -- Add an appropriate section to the case statement in sprint.adb
93 -- Add an appropriate section to the case statement in sem.adb
94 -- Add an appropriate section to the case statement in exp_util.adb
95 -- (Insert_Actions procedure)
96 -- For a subexpression, add an appropriate section to the case
97 -- statement in sem_eval.adb
98 -- For a subexpression, add an appropriate section to the case
99 -- statement in sem_res.adb
101 -- Finally, four utility programs must be run:
103 -- (Optional.) Run CSinfo to check that you have made the changes
104 -- consistently. It checks most of the rules given above. This utility
105 -- reads sinfo.ads and sinfo.adb and generates a report to standard
106 -- output. This step is optional because XSinfo runs CSinfo.
108 -- Run XSinfo to create sinfo.h, the corresponding C header. This
109 -- utility reads sinfo.ads and generates sinfo.h. Note that it does
110 -- not need to read sinfo.adb, since the contents of the body are
111 -- algorithmically determinable from the spec.
113 -- Run XTreeprs to create treeprs.ads, an updated version of the module
114 -- that is used to drive the tree print routine. This utility reads (but
115 -- does not modify) treeprs.adt, the template that provides the basic
116 -- structure of the file, and then fills in the data from the comments
119 -- Run XNmake to create nmake.ads and nmake.adb, the package body and
120 -- spec of the Nmake package which contains functions for constructing
123 -- The above steps are done automatically by the build scripts when you do
126 -- Note: sometime we could write a utility that actually generated the body
127 -- of sinfo from the spec instead of simply checking it, since, as noted
128 -- above, the contents of the body can be determined from the spec.
130 --------------------------------
131 -- Implicit Nodes in the Tree --
132 --------------------------------
134 -- Generally the structure of the tree very closely follows the grammar as
135 -- defined in the RM. However, certain nodes are omitted to save space and
136 -- simplify semantic processing. Two general classes of such omitted nodes
139 -- If the only possibilities for a non-terminal are one or more other
140 -- non-terminals (i.e. the rule is a "skinny" rule), then usually the
141 -- corresponding node is omitted from the tree, and the target construct
142 -- appears directly. For example, a real type definition is either
143 -- floating point definition or a fixed point definition. No explicit node
144 -- appears for real type definition. Instead either the floating point
145 -- definition or fixed point definition appears directly.
147 -- If a non-terminal corresponds to a list of some other non-terminal
148 -- (possibly with separating punctuation), then usually it is omitted from
149 -- the tree, and a list of components appears instead. For example,
150 -- sequence of statements does not appear explicitly in the tree. Instead
151 -- a list of statements appears directly.
153 -- Some additional cases of omitted nodes occur and are documented
154 -- individually. In particular, many nodes are omitted in the tree
155 -- generated for an expression.
157 -------------------------------------------
158 -- Handling of Defining Identifier Lists --
159 -------------------------------------------
161 -- In several declarative forms in the syntax, lists of defining
162 -- identifiers appear (object declarations, component declarations, number
163 -- declarations etc.)
165 -- The semantics of such statements are equivalent to a series of identical
166 -- declarations of single defining identifiers (except that conformance
167 -- checks require the same grouping of identifiers in the parameter case).
169 -- To simplify semantic processing, the parser breaks down such multiple
170 -- declaration cases into sequences of single declarations, duplicating
171 -- type and initialization information as required. The flags More_Ids and
172 -- Prev_Ids are used to record the original form of the source in the case
173 -- where the original source used a list of names, More_Ids being set on
174 -- all but the last name and Prev_Ids being set on all but the first name.
175 -- These flags are used to reconstruct the original source (e.g. in the
176 -- Sprint package), and also are included in the conformance checks, but
177 -- otherwise have no semantic significance.
179 -- Note: the reason that we use More_Ids and Prev_Ids rather than
180 -- First_Name and Last_Name flags is so that the flags are off in the
181 -- normal one identifier case, which minimizes tree print output.
183 -----------------------
184 -- Use of Node Lists --
185 -----------------------
187 -- With a few exceptions, if a construction of the form {non-terminal}
188 -- appears in the tree, lists are used in the corresponding tree node (see
189 -- package Nlists for handling of node lists). In this case a field of the
190 -- parent node points to a list of nodes for the non-terminal. The field
191 -- name for such fields has a plural name which always ends in "s". For
192 -- example, a case statement has a field Alternatives pointing to list of
193 -- case statement alternative nodes.
195 -- Only fields pointing to lists have names ending in "s", so generally the
196 -- structure is strongly typed, fields not ending in s point to single
197 -- nodes, and fields ending in s point to lists.
199 -- The following example shows how a traversal of a list is written. We
200 -- suppose here that Stmt points to a N_Case_Statement node which has a
201 -- list field called Alternatives:
203 -- Alt := First (Alternatives (Stmt));
204 -- while Present (Alt) loop
206 -- -- processing for case statement alternative Alt
208 -- Alt := Next (Alt);
211 -- The Present function tests for Empty, which in this case signals the end
212 -- of the list. First returns Empty immediately if the list is empty.
213 -- Present is defined in Atree, First and Next are defined in Nlists.
215 -- The exceptions to this rule occur with {DEFINING_IDENTIFIERS} in all
216 -- contexts, which is handled as described in the previous section, and
217 -- with {,library_unit_NAME} in the N_With_Clause mode, which is handled
218 -- using the First_Name and Last_Name flags, as further detailed in the
219 -- description of the N_With_Clause node.
225 -- Pragmas can appear in many different context, but are not included in
226 -- the grammar. Still they must appear in the tree, so they can be properly
229 -- Two approaches are used. In some cases, an extra field is defined in an
230 -- appropriate node that contains a list of pragmas appearing in the
231 -- expected context. For example pragmas can appear before an
232 -- Accept_Alternative in a Selective_Accept_Statement, and these pragmas
233 -- appear in the Pragmas_Before field of the N_Accept_Alternative node.
235 -- The other approach is to simply allow pragmas to appear in syntactic
236 -- lists where the grammar (of course) does not include the possibility.
237 -- For example, the Variants field of an N_Variant_Part node points to a
238 -- list that can contain both N_Pragma and N_Variant nodes.
240 -- To make processing easier in the latter case, the Nlists package
241 -- provides a set of routines (First_Non_Pragma, Last_Non_Pragma,
242 -- Next_Non_Pragma, Prev_Non_Pragma) that allow such lists to be handled
243 -- ignoring all pragmas.
245 -- In the case of the variants list, we can either write:
247 -- Variant := First (Variants (N));
248 -- while Present (Variant) loop
250 -- Variant := Next (Variant);
255 -- Variant := First_Non_Pragma (Variants (N));
256 -- while Present (Variant) loop
258 -- Variant := Next_Non_Pragma (Variant);
261 -- In the first form of the loop, Variant can either be an N_Pragma or an
262 -- N_Variant node. In the second form, Variant can only be N_Variant since
263 -- all pragmas are skipped.
265 ---------------------
266 -- Optional Fields --
267 ---------------------
269 -- Fields which correspond to a section of the syntax enclosed in square
270 -- brackets are generally omitted (and the corresponding field set to Empty
271 -- for a node, or No_List for a list). The documentation of such fields
272 -- notes these cases. One exception to this rule occurs in the case of
273 -- possibly empty statement sequences (such as the sequence of statements
274 -- in an entry call alternative). Such cases appear in the syntax rules as
275 -- [SEQUENCE_OF_STATEMENTS] and the fields corresponding to such optional
276 -- statement sequences always contain an empty list (not No_List) if no
277 -- statements are present.
279 -- Note: the utility program that constructs the body and spec of the Nmake
280 -- package relies on the format of the comments to determine if a field
281 -- should have a default value in the corresponding make routine. The rule
282 -- is that if the first line of the description of the field contains the
283 -- string "(set to xxx if", then a default value of xxx is provided for
284 -- this field in the corresponding Make_yyy routine.
286 -----------------------------------
287 -- Note on Body/Spec Terminology --
288 -----------------------------------
290 -- In informal discussions about Ada, it is customary to refer to package
291 -- and subprogram specs and bodies. However, this is not technically
292 -- correct, what is normally referred to as a spec or specification is in
293 -- fact a package declaration or subprogram declaration. We are careful in
294 -- GNAT to use the correct terminology and in particular, the full word
295 -- specification is never used as an incorrect substitute for declaration.
296 -- The structure and terminology used in the tree also reflects the grammar
297 -- and thus uses declaration and specification in the technically correct
300 -- However, there are contexts in which the informal terminology is useful.
301 -- We have the word "body" to refer to the Interp_Etype declared by the
302 -- declaration of a unit body, and in some contexts we need similar term to
303 -- refer to the entity declared by the package or subprogram declaration,
304 -- and simply using declaration can be confusing since the body also has a
307 -- An example of such a context is the link between the package body and
308 -- its declaration. With_Declaration is confusing, since the package body
309 -- itself is a declaration.
311 -- To deal with this problem, we reserve the informal term Spec, i.e. the
312 -- popular abbreviation used in this context, to refer to the entity
313 -- declared by the package or subprogram declaration. So in the above
314 -- example case, the field in the body is called With_Spec.
316 -- Another important context for the use of the word Spec is in error
317 -- messages, where a hyper-correct use of declaration would be confusing to
318 -- a typical Ada programmer, and even for an expert programmer can cause
319 -- confusion since the body has a declaration as well.
323 -- Declaration always refers to the syntactic entity that is called
324 -- a declaration. In particular, subprogram declaration
325 -- and package declaration are used to describe the
326 -- syntactic entity that includes the semicolon.
328 -- Specification always refers to the syntactic entity that is called
329 -- a specification. In particular, the terms procedure
330 -- specification, function specification, package
331 -- specification, subprogram specification always refer
332 -- to the syntactic entity that has no semicolon.
334 -- Spec is an informal term, used to refer to the entity
335 -- that is declared by a task declaration, protected
336 -- declaration, generic declaration, subprogram
337 -- declaration or package declaration.
339 -- This convention is followed throughout the GNAT documentation
340 -- both internal and external, and in all error message text.
342 ------------------------
343 -- Internal Use Nodes --
344 ------------------------
346 -- These are Node_Kind settings used in the internal implementation which
347 -- are not logically part of the specification.
350 -- Completely unused entry at the start of the enumeration type. This
351 -- is inserted so that no legitimate value is zero, which helps to get
352 -- better debugging behavior, since zero is a likely uninitialized value).
355 -- Completely unused entry at the end of the enumeration type. This is
356 -- handy so that arrays with Node_Kind as the index type have an extra
357 -- entry at the end (see for example the use of the Pchar_Pos_Array in
358 -- Treepr, where the extra entry provides the limit value when dealing with
359 -- the last used entry in the array).
361 -----------------------------------------
362 -- Note on the settings of Sloc fields --
363 -----------------------------------------
365 -- The Sloc field of nodes that come from the source is set by the parser.
366 -- For internal nodes, and nodes generated during expansion the Sloc is
367 -- usually set in the call to the constructor for the node. In general the
368 -- Sloc value chosen for an internal node is the Sloc of the source node
369 -- whose processing is responsible for the expansion. For example, the Sloc
370 -- of an inherited primitive operation is the Sloc of the corresponding
371 -- derived type declaration.
373 -- For the nodes of a generic instantiation, the Sloc value is encoded to
374 -- represent both the original Sloc in the generic unit, and the Sloc of
375 -- the instantiation itself. See Sinput.ads for details.
377 -- Subprogram instances create two callable entities: one is the visible
378 -- subprogram instance, and the other is an anonymous subprogram nested
379 -- within a wrapper package that contains the renamings for the actuals.
380 -- Both of these entities have the Sloc of the defining entity in the
381 -- instantiation node. This simplifies some ASIS queries.
383 -----------------------
384 -- Field Definitions --
385 -----------------------
387 -- In the following node definitions, all fields, both syntactic and
388 -- semantic, are documented. The one exception is in the case of entities
389 -- (defining identifiers, character literals and operator symbols), where
390 -- the usage of the fields depends on the entity kind. Entity fields are
391 -- fully documented in the separate package Einfo.
393 -- In the node definitions, three common sets of fields are abbreviated to
394 -- save both space in the documentation, and also space in the string
395 -- (defined in Tree_Print_Strings) used to print trees. The following
396 -- abbreviations are used:
398 -- Note: the utility program that creates the Treeprs spec (in the file
399 -- xtreeprs.adb) knows about the special fields here, so it must be
400 -- modified if any change is made to these fields.
402 -- "plus fields for binary operator"
403 -- Chars (Name1) Name_Id for the operator
404 -- Left_Opnd (Node2) left operand expression
405 -- Right_Opnd (Node3) right operand expression
406 -- Entity (Node4-Sem) defining entity for operator
407 -- Associated_Node (Node4-Sem) for generic processing
408 -- Do_Overflow_Check (Flag17-Sem) set if overflow check needed
409 -- Has_Private_View (Flag11-Sem) set in generic units.
411 -- "plus fields for unary operator"
412 -- Chars (Name1) Name_Id for the operator
413 -- Right_Opnd (Node3) right operand expression
414 -- Entity (Node4-Sem) defining entity for operator
415 -- Associated_Node (Node4-Sem) for generic processing
416 -- Do_Overflow_Check (Flag17-Sem) set if overflow check needed
417 -- Has_Private_View (Flag11-Sem) set in generic units.
419 -- "plus fields for expression"
420 -- Paren_Count number of parentheses levels
421 -- Etype (Node5-Sem) type of the expression
422 -- Is_Overloaded (Flag5-Sem) >1 type interpretation exists
423 -- Is_Static_Expression (Flag6-Sem) set for static expression
424 -- Raises_Constraint_Error (Flag7-Sem) evaluation raises CE
425 -- Must_Not_Freeze (Flag8-Sem) set if must not freeze
426 -- Do_Range_Check (Flag9-Sem) set if a range check needed
427 -- Has_Dynamic_Length_Check (Flag10-Sem) set if length check inserted
428 -- Has_Dynamic_Range_Check (Flag12-Sem) set if range check inserted
429 -- Assignment_OK (Flag15-Sem) set if modification is OK
430 -- Is_Controlling_Actual (Flag16-Sem) set for controlling argument
432 -- Note: see under (EXPRESSION) for further details on the use of
433 -- the Paren_Count field to record the number of parentheses levels.
435 -- Node_Kind is the type used in the Nkind field to indicate the node kind.
436 -- The actual definition of this type is given later (the reason for this
437 -- is that we want the descriptions ordered by logical chapter in the RM,
438 -- but the type definition is reordered to facilitate the definition of
439 -- some subtype ranges. The individual descriptions of the nodes show how
440 -- the various fields are used in each node kind, as well as providing
441 -- logical names for the fields. Functions and procedures are provided for
442 -- accessing and setting these fields using these logical names.
444 -----------------------
445 -- Gigi Restrictions --
446 -----------------------
448 -- The tree passed to Gigi is more restricted than the general tree form.
449 -- For example, as a result of expansion, most of the tasking nodes can
450 -- never appear. For each node to which either a complete or partial
451 -- restriction applies, a note entitled "Gigi restriction" appears which
452 -- documents the restriction.
454 -- Note that most of these restrictions apply only to trees generated when
455 -- code is being generated, since they involved expander actions that
462 -- When a file is compiled in ASIS mode (-gnatct), expansion is skipped,
463 -- and the analysis must generate a tree in a form that meets all ASIS
466 -- ASIS must be able to recover the original tree that corresponds to the
467 -- source. It relies heavily on Original_Node for this purpose, which as
468 -- described in Atree, records the history when a node is rewritten. ASIS
469 -- uses Original_Node to recover the original node before the Rewrite.
471 -- At least in ASIS mode (not really important in non-ASIS mode), when
472 -- N1 is rewritten as N2:
474 -- The subtree rooted by the original node N1 should be fully decorated,
475 -- i.e. all semantic fields noted in sinfo.ads should be set properly
476 -- and any referenced entities should be complete (with exceptions for
477 -- representation information, noted below).
479 -- For all the direct descendants of N1 (original node) their Parent
480 -- links should point not to N1, but to N2 (rewriting node).
482 -- The Parent links of rewritten nodes (N1 in this example) are set in
483 -- some cases (to point to the rewritten parent), but in other cases
484 -- they are set to Empty. This needs sorting out ??? It would be much
485 -- cleaner if they could always be set in the original node ???
487 -- Representation Information
489 -- For the purposes of the data description annex, the representation
490 -- information for source declared entities must be complete in the
493 -- This requires that the front end call the back end (gigi/gcc) in
494 -- a special "back annotate only" mode to obtain information on layout
495 -- from the back end.
497 -- For the purposes of this special "back annotate only" mode, the
498 -- requirements that would normally need to be met to generate code
499 -- are relaxed as follows:
501 -- Anonymous types need not have full representation information (e.g.
502 -- sizes need not be set for types where the front end would normally
503 -- set the sizes), since anonymous types can be ignored in this mode.
505 -- In this mode, gigi will see at least fragments of a fully annotated
506 -- unexpanded tree. This means that it will encounter nodes it does
507 -- not normally handle (such as stubs, task bodies etc). It should
508 -- simply ignore these nodes, since they are not relevant to the task
509 -- of back annotating representation information.
511 ------------------------
512 -- Common Flag Fields --
513 ------------------------
515 -- The following flag fields appear in all nodes
518 -- This flag is used to indicate that a node (and all its children have
519 -- been analyzed. It is used to avoid reanalysis of a node that has
520 -- already been analyzed, both for efficiency and functional correctness
524 -- This flag is set if the node comes directly from an explicit construct
525 -- in the source. It is normally on for any nodes built by the scanner or
526 -- parser from the source program, with the exception that in a few cases
527 -- the parser adds nodes to normalize the representation (in particular
528 -- a null statement is added to a package body if there is no begin/end
529 -- initialization section.
531 -- Most nodes inserted by the analyzer or expander are not considered
532 -- as coming from source, so the flag is off for such nodes. In a few
533 -- cases, the expander constructs nodes closely equivalent to nodes
534 -- from the source program (e.g. the allocator built for build-in-place
535 -- case), and the Comes_From_Source flag is deliberately set.
538 -- This flag is used to avoid multiple error messages being posted on or
539 -- referring to the same node. This flag is set if an error message
540 -- refers to a node or is posted on its source location, and has the
541 -- effect of inhibiting further messages involving this same node.
543 ------------------------------------
544 -- Description of Semantic Fields --
545 ------------------------------------
547 -- The meaning of the syntactic fields is generally clear from their names
548 -- without any further description, since the names are chosen to
549 -- correspond very closely to the syntax in the reference manual. This
550 -- section describes the usage of the semantic fields, which are used to
551 -- contain additional information determined during semantic analysis.
553 -- ABE_Is_Certain (Flag18-Sem)
554 -- This flag is set in an instantiation node or a call node is determined
555 -- to be sure to raise an ABE. This is used to trigger special handling
556 -- of such cases, particularly in the instantiation case where we avoid
557 -- instantiating the body if this flag is set. This flag is also present
558 -- in an N_Formal_Package_Declaration_Node since formal package
559 -- declarations are treated like instantiations, but it is always set to
560 -- False in this context.
562 -- Accept_Handler_Records (List5-Sem)
563 -- This field is present only in an N_Accept_Alternative node. It is used
564 -- to temporarily hold the exception handler records from an accept
565 -- statement in a selective accept. These exception handlers will
566 -- eventually be placed in the Handler_Records list of the procedure
567 -- built for this accept (see Expand_N_Selective_Accept procedure in
568 -- Exp_Ch9 for further details).
570 -- Access_Types_To_Process (Elist2-Sem)
571 -- Present in N_Freeze_Entity nodes for Incomplete or private types.
572 -- Contains the list of access types which may require specific treatment
573 -- when the nature of the type completion is completely known. An example
574 -- of such treatment is the generation of the associated_final_chain.
576 -- Actions (List1-Sem)
577 -- This field contains a sequence of actions that are associated with the
578 -- node holding the field. See the individual node types for details of
579 -- how this field is used, as well as the description of the specific use
580 -- for a particular node type.
582 -- Activation_Chain_Entity (Node3-Sem)
583 -- This is used in tree nodes representing task activators (blocks,
584 -- subprogram bodies, package declarations, and task bodies). It is
585 -- initially Empty, and then gets set to point to the entity for the
586 -- declared Activation_Chain variable when the first task is declared.
587 -- When tasks are declared in the corresponding declarative region this
588 -- entity is located by name (its name is always _Chain) and the declared
589 -- tasks are added to the chain. Note that N_Extended_Return_Statement
590 -- does not have this attribute, although it does have an activation
591 -- chain. This chain is used to store the tasks temporarily, and is not
592 -- used for activating them. On successful completion of the return
593 -- statement, the tasks are moved to the caller's chain, and the caller
596 -- Acts_As_Spec (Flag4-Sem)
597 -- A flag set in the N_Subprogram_Body node for a subprogram body which
598 -- is acting as its own spec, except in the case of a library level
599 -- subprogram, in which case the flag is set on the parent compilation
600 -- unit node instead (see further description in spec of Lib package).
601 -- ??? Above note about Lib is dubious since lib.ads does not mention
602 -- Acts_As_Spec at all.
604 -- Actual_Designated_Subtype (Node4-Sem)
605 -- Present in N_Free_Statement and N_Explicit_Dereference nodes. If gigi
606 -- needs to known the dynamic constrained subtype of the designated
607 -- object, this attribute is set to that type. This is done for
608 -- N_Free_Statements for access-to-classwide types and access to
609 -- unconstrained packed array types, and for N_Explicit_Dereference when
610 -- the designated type is an unconstrained packed array and the
611 -- dereference is the prefix of a 'Size attribute reference.
613 -- Address_Warning_Posted (Flag18-Sem)
614 -- Present in N_Attribute_Definition nodes. Set to indicate that we have
615 -- posted a warning for the address clause regarding size or alignment
616 -- issues. Used to inhibit multiple redundant messages.
618 -- Aggregate_Bounds (Node3-Sem)
619 -- Present in array N_Aggregate nodes. If the bounds of the aggregate are
620 -- known at compile time, this field points to an N_Range node with those
621 -- bounds. Otherwise Empty.
623 -- All_Others (Flag11-Sem)
624 -- Present in an N_Others_Choice node. This flag is set for an others
625 -- exception where all exceptions are to be caught, even those that are
626 -- not normally handled (in particular the tasking abort signal). This
627 -- is used for translation of the at end handler into a normal exception
630 -- Aspect_Rep_Item (Node2-Sem)
631 -- Present in N_Aspect_Specification nodes. Points to the corresponding
632 -- pragma/attribute definition node used to process the aspect.
634 -- Assignment_OK (Flag15-Sem)
635 -- This flag is set in a subexpression node for an object, indicating
636 -- that the associated object can be modified, even if this would not
637 -- normally be permissible (either by direct assignment, or by being
638 -- passed as an out or in-out parameter). This is used by the expander
639 -- for a number of purposes, including initialization of constants and
640 -- limited type objects (such as tasks), setting discriminant fields,
641 -- setting tag values, etc. N_Object_Declaration nodes also have this
642 -- flag defined. Here it is used to indicate that an initialization
643 -- expression is valid, even where it would normally not be allowed
644 -- (e.g. where the type involved is limited).
646 -- Associated_Node (Node4-Sem)
647 -- Present in nodes that can denote an entity: identifiers, character
648 -- literals, operator symbols, expanded names, operator nodes, and
649 -- attribute reference nodes (all these nodes have an Entity field).
650 -- This field is also present in N_Aggregate, N_Selected_Component, and
651 -- N_Extension_Aggregate nodes. This field is used in generic processing
652 -- to create links between the generic template and the generic copy.
653 -- See Sem_Ch12.Get_Associated_Node for full details. Note that this
654 -- field overlaps Entity, which is fine, since, as explained in Sem_Ch12,
655 -- the normal function of Entity is not required at the point where the
656 -- Associated_Node is set. Note also, that in generic templates, this
657 -- means that the Entity field does not necessarily point to an Entity.
658 -- Since the back end is expected to ignore generic templates, this is
661 -- Atomic_Sync_Required (Flag14-Sem)
662 -- This flag is set on a node for which atomic synchronization is
663 -- required for the corresponding reference or modification.
665 -- At_End_Proc (Node1)
666 -- This field is present in an N_Handled_Sequence_Of_Statements node.
667 -- It contains an identifier reference for the cleanup procedure to be
668 -- called. See description of this node for further details.
670 -- Backwards_OK (Flag6-Sem)
671 -- A flag present in the N_Assignment_Statement node. It is used only
672 -- if the type being assigned is an array type, and is set if analysis
673 -- determines that it is definitely safe to do the copy backwards, i.e.
674 -- starting at the highest addressed element. This is the case if either
675 -- the operands do not overlap, or they may overlap, but if they do,
676 -- then the left operand is at a higher address than the right operand.
678 -- Note: If neither of the flags Forwards_OK or Backwards_OK is set, it
679 -- means that the front end could not determine that either direction is
680 -- definitely safe, and a runtime check may be required if the backend
681 -- cannot figure it out. If both flags Forwards_OK and Backwards_OK are
682 -- set, it means that the front end can assure no overlap of operands.
684 -- Body_To_Inline (Node3-Sem)
685 -- present in subprogram declarations. Denotes analyzed but unexpanded
686 -- body of subprogram, to be used when inlining calls. Present when the
687 -- subprogram has an Inline pragma and inlining is enabled. If the
688 -- declaration is completed by a renaming_as_body, and the renamed en-
689 -- tity is a subprogram, the Body_To_Inline is the name of that entity,
690 -- which is used directly in later calls to the original subprogram.
692 -- Body_Required (Flag13-Sem)
693 -- A flag that appears in the N_Compilation_Unit node indicating that
694 -- the corresponding unit requires a body. For the package case, this
695 -- indicates that a completion is required. In Ada 95, if the flag is not
696 -- set for the package case, then a body may not be present. In Ada 83,
697 -- if the flag is not set for the package case, then body is optional.
698 -- For a subprogram declaration, the flag is set except in the case where
699 -- a pragma Import or Interface applies, in which case no body is
700 -- permitted (in Ada 83 or Ada 95).
702 -- By_Ref (Flag5-Sem)
703 -- Present in N_Simple_Return_Statement and N_Extended_Return_Statement,
704 -- this flag is set when the returned expression is already allocated on
705 -- the secondary stack and thus the result is passed by reference rather
706 -- than copied another time.
708 -- Check_Address_Alignment (Flag11-Sem)
709 -- A flag present in N_Attribute_Definition clause for a 'Address
710 -- attribute definition. This flag is set if a dynamic check should be
711 -- generated at the freeze point for the entity to which this address
712 -- clause applies. The reason that we need this flag is that we want to
713 -- check for range checks being suppressed at the point where the
714 -- attribute definition clause is given, rather than testing this at the
717 -- Comes_From_Extended_Return_Statement (Flag18-Sem)
718 -- Present in N_Simple_Return_Statement nodes. True if this node was
719 -- constructed as part of the N_Extended_Return_Statement expansion.
721 -- Compile_Time_Known_Aggregate (Flag18-Sem)
722 -- Present in N_Aggregate nodes. Set for aggregates which can be fully
723 -- evaluated at compile time without raising constraint error. Such
724 -- aggregates can be passed as is the back end without any expansion.
725 -- See Exp_Aggr for specific conditions under which this flag gets set.
727 -- Componentwise_Assignment (Flag14-Sem)
728 -- Present in N_Assignment_Statement nodes. Set for a record assignment
729 -- where all that needs doing is to expand it into component-by-component
730 -- assignments. This is used internally for the case of tagged types with
731 -- rep clauses, where we need to avoid recursion (we don't want to try to
732 -- generate a call to the primitive operation, because this is the case
733 -- where we are compiling the primitive operation). Note that when we are
734 -- expanding component assignments in this case, we never assign the _tag
735 -- field, but we recursively assign components of the parent type.
737 -- Condition_Actions (List3-Sem)
738 -- This field appears in else-if nodes and in the iteration scheme node
739 -- for while loops. This field is only used during semantic processing to
740 -- temporarily hold actions inserted into the tree. In the tree passed
741 -- to gigi, the condition actions field is always set to No_List. For
742 -- details on how this field is used, see the routine Insert_Actions in
743 -- package Exp_Util, and also the expansion routines for the relevant
746 -- Context_Pending (Flag16-Sem)
747 -- This field appears in Compilation_Unit nodes, to indicate that the
748 -- context of the unit is being compiled. Used to detect circularities
749 -- that are not otherwise detected by the loading mechanism. Such
750 -- circularities can occur in the presence of limited and non-limited
751 -- with_clauses that mention the same units.
753 -- Controlling_Argument (Node1-Sem)
754 -- This field is set in procedure and function call nodes if the call
755 -- is a dispatching call (it is Empty for a non-dispatching call). It
756 -- indicates the source of the call's controlling tag. For procedure
757 -- calls, the Controlling_Argument is one of the actuals. For function
758 -- that has a dispatching result, it is an entity in the context of the
759 -- call that can provide a tag, or else it is the tag of the root type
760 -- of the class. It can also specify a tag directly rather than being a
761 -- tagged object. The latter is needed by the implementations of AI-239
764 -- Conversion_OK (Flag14-Sem)
765 -- A flag set on type conversion nodes to indicate that the conversion
766 -- is to be considered as being valid, even though it is the case that
767 -- the conversion is not valid Ada. This is used for attributes Enum_Rep,
768 -- Fixed_Value and Integer_Value, for internal conversions done for
769 -- fixed-point operations, and for certain conversions for calls to
770 -- initialization procedures. If Conversion_OK is set, then Etype must be
771 -- set (the analyzer assumes that Etype has been set). For the case of
772 -- fixed-point operands, it also indicates that the conversion is to be
773 -- direct conversion of the underlying integer result, with no regard to
774 -- the small operand.
776 -- Convert_To_Return_False (Flag13-Sem)
777 -- Present in N_Raise_Expression nodes that appear in the body of the
778 -- special predicateM function used to test a predicate in the context
779 -- of a membership test, where raise expression results in returning a
780 -- value of False rather than raising an exception.
782 -- Corresponding_Aspect (Node3-Sem)
783 -- Present in N_Pragma node. Used to point back to the source aspect from
784 -- the corresponding pragma. This field is Empty for source pragmas.
786 -- Corresponding_Body (Node5-Sem)
787 -- This field is set in subprogram declarations, package declarations,
788 -- entry declarations of protected types, and in generic units. It points
789 -- to the defining entity for the corresponding body (NOT the node for
792 -- Corresponding_Formal_Spec (Node3-Sem)
793 -- This field is set in subprogram renaming declarations, where it points
794 -- to the defining entity for a formal subprogram in the case where the
795 -- renaming corresponds to a generic formal subprogram association in an
796 -- instantiation. The field is Empty if the renaming does not correspond
797 -- to such a formal association.
799 -- Corresponding_Generic_Association (Node5-Sem)
800 -- This field is defined for object declarations and object renaming
801 -- declarations. It is set for the declarations within an instance that
802 -- map generic formals to their actuals. If set, the field points to
803 -- a generic_association which is the original parent of the expression
804 -- or name appearing in the declaration. This simplifies ASIS queries.
806 -- Corresponding_Integer_Value (Uint4-Sem)
807 -- This field is set in real literals of fixed-point types (it is not
808 -- used for floating-point types). It contains the integer value used
809 -- to represent the fixed-point value. It is also set on the universal
810 -- real literals used to represent bounds of fixed-point base types
811 -- and their first named subtypes.
813 -- Corresponding_Spec (Node5-Sem)
814 -- This field is set in subprogram, package, task, and protected body
815 -- nodes, where it points to the defining entity in the corresponding
816 -- spec. The attribute is also set in N_With_Clause nodes where it points
817 -- to the defining entity for the with'ed spec, and in a subprogram
818 -- renaming declaration when it is a Renaming_As_Body. The field is Empty
819 -- if there is no corresponding spec, as in the case of a subprogram body
820 -- that serves as its own spec.
822 -- In Ada 2012, Corresponding_Spec is set on expression functions that
823 -- complete a subprogram declaration.
825 -- Corresponding_Spec_Of_Stub (Node2-Sem)
826 -- This field is present in subprogram, package, task and protected body
827 -- stubs where it points to the corresponding spec of the stub. Due to
828 -- clashes in the structure of nodes, we cannot use Corresponding_Spec.
830 -- Corresponding_Stub (Node3-Sem)
831 -- This field is present in an N_Subunit node. It holds the node in
832 -- the parent unit that is the stub declaration for the subunit. It is
833 -- set when analysis of the stub forces loading of the proper body. If
834 -- expansion of the proper body creates new declarative nodes, they are
835 -- inserted at the point of the corresponding_stub.
837 -- Dcheck_Function (Node5-Sem)
838 -- This field is present in an N_Variant node, It references the entity
839 -- for the discriminant checking function for the variant.
841 -- Default_Expression (Node5-Sem)
842 -- This field is Empty if there is no default expression. If there is a
843 -- simple default expression (one with no side effects), then this field
844 -- simply contains a copy of the Expression field (both point to the tree
845 -- for the default expression). Default_Expression is used for
846 -- conformance checking.
848 -- Default_Storage_Pool (Node3-Sem)
849 -- This field is present in N_Compilation_Unit_Aux nodes. It is set to a
850 -- copy of Opt.Default_Pool at the end of the compilation unit. See
851 -- package Opt for details. This is used for inheriting the
852 -- Default_Storage_Pool in child units.
854 -- Discr_Check_Funcs_Built (Flag11-Sem)
855 -- This flag is present in N_Full_Type_Declaration nodes. It is set when
856 -- discriminant checking functions are constructed. The purpose is to
857 -- avoid attempting to set these functions more than once.
859 -- Do_Accessibility_Check (Flag13-Sem)
860 -- This flag is set on N_Parameter_Specification nodes to indicate
861 -- that an accessibility check is required for the parameter. It is
862 -- not yet decided who takes care of this check (TBD ???).
864 -- Do_Discriminant_Check (Flag13-Sem)
865 -- This flag is set on N_Selected_Component nodes to indicate that a
866 -- discriminant check is required using the discriminant check routine
867 -- associated with the selector. The actual check is generated by the
868 -- expander when processing selected components. In the case of
869 -- Unchecked_Union, the flag is also set, but no discriminant check
870 -- routine is associated with the selector, and the expander does not
873 -- Do_Division_Check (Flag13-Sem)
874 -- This flag is set on a division operator (/ mod rem) to indicate
875 -- that a zero divide check is required. The actual check is dealt
876 -- with by the backend (all the front end does is to set the flag).
878 -- Do_Length_Check (Flag4-Sem)
879 -- This flag is set in an N_Assignment_Statement, N_Op_And, N_Op_Or,
880 -- N_Op_Xor, or N_Type_Conversion node to indicate that a length check
881 -- is required. It is not determined who deals with this flag (???).
883 -- Do_Overflow_Check (Flag17-Sem)
884 -- This flag is set on an operator where an overflow check is required on
885 -- the operation. The actual check is dealt with by the backend (all the
886 -- front end does is to set the flag). The other cases where this flag is
887 -- used is on a Type_Conversion node and for attribute reference nodes.
888 -- For a type conversion, it means that the conversion is from one base
889 -- type to another, and the value may not fit in the target base type.
890 -- See also the description of Do_Range_Check for this case. The only
891 -- attribute references which use this flag are Pred and Succ, where it
892 -- means that the result should be checked for going outside the base
893 -- range. Note that this flag is not set for modular types. This flag is
894 -- also set on if and case expression nodes if we are operating in either
895 -- MINIMIZED or ELIMINATED overflow checking mode (to make sure that we
896 -- properly process overflow checking for dependent expressions).
898 -- Do_Range_Check (Flag9-Sem)
899 -- This flag is set on an expression which appears in a context where a
900 -- range check is required. The target type is clear from the context.
901 -- The contexts in which this flag can appear are the following:
903 -- Right side of an assignment. In this case the target type is
904 -- taken from the left side of the assignment, which is referenced
905 -- by the Name of the N_Assignment_Statement node.
907 -- Subscript expressions in an indexed component. In this case the
908 -- target type is determined from the type of the array, which is
909 -- referenced by the Prefix of the N_Indexed_Component node.
911 -- Argument expression for a parameter, appearing either directly in
912 -- the Parameter_Associations list of a call or as the Expression of an
913 -- N_Parameter_Association node that appears in this list. In either
914 -- case, the check is against the type of the formal. Note that the
915 -- flag is relevant only in IN and IN OUT parameters, and will be
916 -- ignored for OUT parameters, where no check is required in the call,
917 -- and if a check is required on the return, it is generated explicitly
918 -- with a type conversion.
920 -- Initialization expression for the initial value in an object
921 -- declaration. In this case the Do_Range_Check flag is set on
922 -- the initialization expression, and the check is against the
923 -- range of the type of the object being declared.
925 -- The expression of a type conversion. In this case the range check is
926 -- against the target type of the conversion. See also the use of
927 -- Do_Overflow_Check on a type conversion. The distinction is that the
928 -- overflow check protects against a value that is outside the range of
929 -- the target base type, whereas a range check checks that the
930 -- resulting value (which is a value of the base type of the target
931 -- type), satisfies the range constraint of the target type.
933 -- Note: when a range check is required in contexts other than those
934 -- listed above (e.g. in a return statement), an additional type
935 -- conversion node is introduced to represent the required check.
937 -- A special case arises for the arguments of the Pred/Succ attributes.
938 -- Here the range check needed is against First + 1 .. Last (Pred) or
939 -- First .. Last - 1 (Succ) of the corresponding base type. Essentially
940 -- these checks are what would be performed within the implicit body of
941 -- the functions that correspond to these attributes. In these cases,
942 -- the Do_Range check flag is set on the argument to the attribute
943 -- function, and the back end must special case the appropriate range
946 -- Do_Storage_Check (Flag17-Sem)
947 -- This flag is set in an N_Allocator node to indicate that a storage
948 -- check is required for the allocation, or in an N_Subprogram_Body node
949 -- to indicate that a stack check is required in the subprogram prolog.
950 -- The N_Allocator case is handled by the routine that expands the call
951 -- to the runtime routine. The N_Subprogram_Body case is handled by the
952 -- backend, and all the semantics does is set the flag.
954 -- Do_Tag_Check (Flag13-Sem)
955 -- This flag is set on an N_Assignment_Statement, N_Function_Call,
956 -- N_Procedure_Call_Statement, N_Type_Conversion,
957 -- N_Simple_Return_Statement, or N_Extended_Return_Statement
958 -- node to indicate that the tag check can be suppressed. It is not
959 -- yet decided how this flag is used (TBD ???).
961 -- Elaborate_Present (Flag4-Sem)
962 -- This flag is set in the N_With_Clause node to indicate that pragma
963 -- Elaborate pragma appears for the with'ed units.
965 -- Elaborate_All_Desirable (Flag9-Sem)
966 -- This flag is set in the N_With_Clause mode to indicate that the static
967 -- elaboration processing has determined that an Elaborate_All pragma is
968 -- desirable for correct elaboration for this unit.
970 -- Elaborate_All_Present (Flag14-Sem)
971 -- This flag is set in the N_With_Clause node to indicate that a
972 -- pragma Elaborate_All pragma appears for the with'ed units.
974 -- Elaborate_Desirable (Flag11-Sem)
975 -- This flag is set in the N_With_Clause mode to indicate that the static
976 -- elaboration processing has determined that an Elaborate pragma is
977 -- desirable for correct elaboration for this unit.
979 -- Elaboration_Boolean (Node2-Sem)
980 -- This field is present in function and procedure specification nodes.
981 -- If set, it points to the entity for a Boolean flag that must be tested
982 -- for certain calls to check for access before elaboration. See body of
983 -- Sem_Elab for further details. This field is Empty if no elaboration
984 -- boolean is required.
986 -- Else_Actions (List3-Sem)
987 -- This field is present in if expression nodes. During code
988 -- expansion we use the Insert_Actions procedure (in Exp_Util) to insert
989 -- actions at an appropriate place in the tree to get elaborated at the
990 -- right time. For if expressions, we have to be sure that the actions
991 -- for the Else branch are only elaborated if the condition is False.
992 -- The Else_Actions field is used as a temporary parking place for
993 -- these actions. The final tree is always rewritten to eliminate the
994 -- need for this field, so in the tree passed to Gigi, this field is
995 -- always set to No_List.
997 -- Enclosing_Variant (Node2-Sem)
998 -- This field is present in the N_Variant node and identifies the Node_Id
999 -- corresponding to the immediately enclosing variant when the variant is
1000 -- nested, and N_Empty otherwise. Set during semantic processing of the
1001 -- variant part of a record type.
1003 -- Entity (Node4-Sem)
1004 -- Appears in all direct names (identifiers, character literals, and
1005 -- operator symbols), as well as expanded names, and attributes that
1006 -- denote entities, such as 'Class. Points to entity for corresponding
1007 -- defining occurrence. Set after name resolution. For identifiers in a
1008 -- WITH list, the corresponding defining occurrence is in a separately
1009 -- compiled file, and Entity must be set by the library Load procedure.
1011 -- Note: During name resolution, the value in Entity may be temporarily
1012 -- incorrect (e.g. during overload resolution, Entity is initially set to
1013 -- the first possible correct interpretation, and then later modified if
1014 -- necessary to contain the correct value after resolution).
1016 -- Note: This field overlaps Associated_Node, which is used during
1017 -- generic processing (see Sem_Ch12 for details). Note also that in
1018 -- generic templates, this means that the Entity field does not always
1019 -- point to an Entity. Since the back end is expected to ignore generic
1020 -- templates, this is harmless.
1022 -- Note: This field also appears in N_Attribute_Definition_Clause nodes.
1023 -- It is used only for stream attributes definition clauses. In this
1024 -- case, it denotes a (possibly dummy) subprogram entity that is declared
1025 -- conceptually at the point of the clause. Thus the visibility of the
1026 -- attribute definition clause (in the sense of 8.3(23) as amended by
1027 -- AI-195) can be checked by testing the visibility of that subprogram.
1029 -- Note: Normally the Entity field of an identifier points to the entity
1030 -- for the corresponding defining identifier, and hence the Chars field
1031 -- of an identifier will match the Chars field of the entity. However,
1032 -- there is no requirement that these match, and there are obscure cases
1033 -- of generated code where they do not match.
1035 -- Note: Ada 2012 aspect specifications require additional links between
1036 -- identifiers and various attributes. These attributes can be of
1037 -- arbitrary types, and the entity field of identifiers that denote
1038 -- aspects must be used to store arbitrary expressions for later semantic
1039 -- checks. See section on aspect specifications for details.
1041 -- Entity_Or_Associated_Node (Node4-Sem)
1042 -- A synonym for both Entity and Associated_Node. Used by convention in
1043 -- the code when referencing this field in cases where it is not known
1044 -- whether the field contains an Entity or an Associated_Node.
1046 -- Etype (Node5-Sem)
1047 -- Appears in all expression nodes, all direct names, and all entities.
1048 -- Points to the entity for the related type. Set after type resolution.
1049 -- Normally this is the actual subtype of the expression. However, in
1050 -- certain contexts such as the right side of an assignment, subscripts,
1051 -- arguments to calls, returned value in a function, initial value etc.
1052 -- it is the desired target type. In the event that this is different
1053 -- from the actual type, the Do_Range_Check flag will be set if a range
1054 -- check is required. Note: if the Is_Overloaded flag is set, then Etype
1055 -- points to an essentially arbitrary choice from the possible set of
1058 -- Exception_Junk (Flag8-Sem)
1059 -- This flag is set in a various nodes appearing in a statement sequence
1060 -- to indicate that the corresponding node is an artifact of the
1061 -- generated code for exception handling, and should be ignored when
1062 -- analyzing the control flow of the relevant sequence of statements
1063 -- (e.g. to check that it does not end with a bad return statement).
1065 -- Exception_Label (Node5-Sem)
1066 -- Appears in N_Push_xxx_Label nodes. Points to the entity of the label
1067 -- to be used for transforming the corresponding exception into a goto,
1068 -- or contains Empty, if this exception is not to be transformed. Also
1069 -- appears in N_Exception_Handler nodes, where, if set, it indicates
1070 -- that there may be a local raise for the handler, so that expansion
1071 -- to allow a goto is required (and this field contains the label for
1072 -- this goto). See Exp_Ch11.Expand_Local_Exception_Handlers for details.
1074 -- Expansion_Delayed (Flag11-Sem)
1075 -- Set on aggregates and extension aggregates that need a top-down rather
1076 -- than bottom-up expansion. Typically aggregate expansion happens bottom
1077 -- up. For nested aggregates the expansion is delayed until the enclosing
1078 -- aggregate itself is expanded, e.g. in the context of a declaration. To
1079 -- delay it we set this flag. This is done to avoid creating a temporary
1080 -- for each level of a nested aggregates, and also to prevent the
1081 -- premature generation of constraint checks. This is also a requirement
1082 -- if we want to generate the proper attachment to the internal
1083 -- finalization lists (for record with controlled components). Top down
1084 -- expansion of aggregates is also used for in-place array aggregate
1085 -- assignment or initialization. When the full context is known, the
1086 -- target of the assignment or initialization is used to generate the
1087 -- left-hand side of individual assignment to each sub-component.
1089 -- First_Inlined_Subprogram (Node3-Sem)
1090 -- Present in the N_Compilation_Unit node for the main program. Points
1091 -- to a chain of entities for subprograms that are to be inlined. The
1092 -- Next_Inlined_Subprogram field of these entities is used as a link
1093 -- pointer with Empty marking the end of the list. This field is Empty
1094 -- if there are no inlined subprograms or inlining is not active.
1096 -- First_Named_Actual (Node4-Sem)
1097 -- Present in procedure call statement and function call nodes, and also
1098 -- in Intrinsic nodes. Set during semantic analysis to point to the first
1099 -- named parameter where parameters are ordered by declaration order (as
1100 -- opposed to the actual order in the call which may be different due to
1101 -- named associations). Note: this field points to the explicit actual
1102 -- parameter itself, not the N_Parameter_Association node (its parent).
1104 -- First_Real_Statement (Node2-Sem)
1105 -- Present in N_Handled_Sequence_Of_Statements node. Normally set to
1106 -- Empty. Used only when declarations are moved into the statement part
1107 -- of a construct as a result of wrapping an AT END handler that is
1108 -- required to cover the declarations. In this case, this field is used
1109 -- to remember the location in the statements list of the first real
1110 -- statement, i.e. the statement that used to be first in the statement
1111 -- list before the declarations were prepended.
1113 -- First_Subtype_Link (Node5-Sem)
1114 -- Present in N_Freeze_Entity node for an anonymous base type that is
1115 -- implicitly created by the declaration of a first subtype. It points
1116 -- to the entity for the first subtype.
1118 -- Float_Truncate (Flag11-Sem)
1119 -- A flag present in type conversion nodes. This is used for float to
1120 -- integer conversions where truncation is required rather than rounding.
1121 -- Note that Gigi does not handle type conversions from real to integer
1122 -- with rounding (see Expand_N_Type_Conversion).
1124 -- Forwards_OK (Flag5-Sem)
1125 -- A flag present in the N_Assignment_Statement node. It is used only
1126 -- if the type being assigned is an array type, and is set if analysis
1127 -- determines that it is definitely safe to do the copy forwards, i.e.
1128 -- starting at the lowest addressed element. This is the case if either
1129 -- the operands do not overlap, or they may overlap, but if they do,
1130 -- then the left operand is at a lower address than the right operand.
1132 -- Note: If neither of the flags Forwards_OK or Backwards_OK is set, it
1133 -- means that the front end could not determine that either direction is
1134 -- definitely safe, and a runtime check may be required if the backend
1135 -- cannot figure it out. If both flags Forwards_OK and Backwards_OK are
1136 -- set, it means that the front end can assure no overlap of operands.
1138 -- From_Aspect_Specification (Flag13-Sem)
1139 -- Processing of aspect specifications typically results in insertion in
1140 -- the tree of corresponding pragma or attribute definition clause nodes.
1141 -- These generated nodes have the From_Aspect_Specification flag set to
1142 -- indicate that they came from aspect specifications originally.
1144 -- From_At_End (Flag4-Sem)
1145 -- This flag is set on an N_Raise_Statement node if it corresponds to
1146 -- the reraise statement generated as the last statement of an AT END
1147 -- handler when SJLJ exception handling is active. It is used to stop
1148 -- a bogus violation of restriction (No_Exception_Propagation), bogus
1149 -- because if the restriction is set, the reraise is not generated.
1151 -- From_At_Mod (Flag4-Sem)
1152 -- This flag is set on the attribute definition clause node that is
1153 -- generated by a transformation of an at mod phrase in a record
1154 -- representation clause. This is used to give slightly different (Ada 83
1155 -- compatible) semantics to such a clause, namely it is used to specify a
1156 -- minimum acceptable alignment for the base type and all subtypes. In
1157 -- Ada 95 terms, the actual alignment of the base type and all subtypes
1158 -- must be a multiple of the given value, and the representation clause
1159 -- is considered to be type specific instead of subtype specific.
1161 -- From_Default (Flag6-Sem)
1162 -- This flag is set on the subprogram renaming declaration created in an
1163 -- instance for a formal subprogram, when the formal is declared with a
1164 -- box, and there is no explicit actual. If the flag is present, the
1165 -- declaration is treated as an implicit reference to the formal in the
1168 -- Generic_Parent (Node5-Sem)
1169 -- Generic_Parent is defined on declaration nodes that are instances. The
1170 -- value of Generic_Parent is the generic entity from which the instance
1171 -- is obtained. Generic_Parent is also defined for the renaming
1172 -- declarations and object declarations created for the actuals in an
1173 -- instantiation. The generic parent of such a declaration is the
1174 -- corresponding generic association in the Instantiation node.
1176 -- Generic_Parent_Type (Node4-Sem)
1177 -- Generic_Parent_Type is defined on Subtype_Declaration nodes for the
1178 -- actuals of formal private and derived types. Within the instance, the
1179 -- operations on the actual are those inherited from the parent. For a
1180 -- formal private type, the parent type is the generic type itself. The
1181 -- Generic_Parent_Type is also used in an instance to determine whether a
1182 -- private operation overrides an inherited one.
1184 -- Handler_List_Entry (Node2-Sem)
1185 -- This field is present in N_Object_Declaration nodes. It is set only
1186 -- for the Handler_Record entry generated for an exception in zero cost
1187 -- exception handling mode. It references the corresponding item in the
1188 -- handler list, and is used to delete this entry if the corresponding
1189 -- handler is deleted during optimization. For further details on why
1190 -- this is required, see Exp_Ch11.Remove_Handler_Entries.
1192 -- Has_Dereference_Action (Flag13-Sem)
1193 -- This flag is present in N_Explicit_Dereference nodes. It is set to
1194 -- indicate that the expansion has aready produced a call to primitive
1195 -- Dereference of a System.Checked_Pools.Checked_Pool implementation.
1196 -- Such dereference actions are produced for debugging purposes.
1198 -- Has_Dynamic_Length_Check (Flag10-Sem)
1199 -- This flag is present in all expression nodes. It is set to indicate
1200 -- that one of the routines in unit Checks has generated a length check
1201 -- action which has been inserted at the flagged node. This is used to
1202 -- avoid the generation of duplicate checks.
1204 -- Has_Dynamic_Range_Check (Flag12-Sem)
1205 -- This flag is present in N_Subtype_Declaration nodes and on all
1206 -- expression nodes. It is set to indicate that one of the routines in
1207 -- unit Checks has generated a range check action which has been inserted
1208 -- at the flagged node. This is used to avoid the generation of duplicate
1209 -- checks. Why does this occur on N_Subtype_Declaration nodes, what does
1210 -- it mean in that context???
1212 -- Has_Local_Raise (Flag8-Sem)
1213 -- Present in exception handler nodes. Set if the handler can be entered
1214 -- via a local raise that gets transformed to a goto statement. This will
1215 -- always be set if Local_Raise_Statements is non-empty, but can also be
1216 -- set as a result of generation of N_Raise_xxx nodes, or flags set in
1217 -- nodes requiring generation of back end checks.
1219 -- Has_No_Elaboration_Code (Flag17-Sem)
1220 -- A flag that appears in the N_Compilation_Unit node to indicate whether
1221 -- or not elaboration code is present for this unit. It is initially set
1222 -- true for subprogram specs and bodies and for all generic units and
1223 -- false for non-generic package specs and bodies. Gigi may set the flag
1224 -- in the non-generic package case if it determines that no elaboration
1225 -- code is generated. Note that this flag is not related to the
1226 -- Is_Preelaborated status, there can be preelaborated packages that
1227 -- generate elaboration code, and non-preelaborated packages which do
1228 -- not generate elaboration code.
1230 -- Has_Pragma_Suppress_All (Flag14-Sem)
1231 -- This flag is set in an N_Compilation_Unit node if the Suppress_All
1232 -- pragma appears anywhere in the unit. This accommodates the rather
1233 -- strange placement rules of other compilers (DEC permits it at the
1234 -- end of a unit, and Rational allows it as a program unit pragma). We
1235 -- allow it anywhere at all, and consider it equivalent to a pragma
1236 -- Suppress (All_Checks) appearing at the start of the configuration
1237 -- pragmas for the unit.
1239 -- Has_Private_View (Flag11-Sem)
1240 -- A flag present in generic nodes that have an entity, to indicate that
1241 -- the node has a private type. Used to exchange private and full
1242 -- declarations if the visibility at instantiation is different from the
1243 -- visibility at generic definition.
1245 -- Has_Relative_Deadline_Pragma (Flag9-Sem)
1246 -- A flag present in N_Subprogram_Body and N_Task_Definition nodes to
1247 -- flag the presence of a pragma Relative_Deadline.
1249 -- Has_Self_Reference (Flag13-Sem)
1250 -- Present in N_Aggregate and N_Extension_Aggregate. Indicates that one
1251 -- of the expressions contains an access attribute reference to the
1252 -- enclosing type. Such a self-reference can only appear in default-
1253 -- initialized aggregate for a record type.
1255 -- Has_SP_Choice (Flag15-Sem)
1256 -- Present in all nodes containing a Discrete_Choices field (N_Variant,
1257 -- N_Case_Expression_Alternative, N_Case_Statement_Alternative). Set to
1258 -- True if the Discrete_Choices list has at least one occurrence of a
1259 -- statically predicated subtype.
1261 -- Has_Storage_Size_Pragma (Flag5-Sem)
1262 -- A flag present in an N_Task_Definition node to flag the presence of a
1263 -- Storage_Size pragma.
1265 -- Has_Wide_Character (Flag11-Sem)
1266 -- Present in string literals, set if any wide character (i.e. character
1267 -- code outside the Character range but within Wide_Character range)
1268 -- appears in the string. Used to implement pragma preference rules.
1270 -- Has_Wide_Wide_Character (Flag13-Sem)
1271 -- Present in string literals, set if any wide character (i.e. character
1272 -- code outside the Wide_Character range) appears in the string. Used to
1273 -- implement pragma preference rules.
1275 -- Header_Size_Added (Flag11-Sem)
1276 -- Present in N_Attribute_Reference nodes, set only for attribute
1277 -- Max_Size_In_Storage_Elements. The flag indicates that the size of the
1278 -- hidden list header used by the runtime finalization support has been
1279 -- added to the size of the prefix. The flag also prevents the infinite
1280 -- expansion of the same attribute in the said context.
1282 -- Hidden_By_Use_Clause (Elist4-Sem)
1283 -- An entity list present in use clauses that appear within
1284 -- instantiations. For the resolution of local entities, entities
1285 -- introduced by these use clauses have priority over global ones, and
1286 -- outer entities must be explicitly hidden/restored on exit.
1288 -- Implicit_With (Flag16-Sem)
1289 -- This flag is set in the N_With_Clause node that is implicitly
1290 -- generated for runtime units that are loaded by the expander, and also
1291 -- for package System, if it is loaded implicitly by a use of the
1292 -- 'Address or 'Tag attribute. ???There are other implicit with clauses
1295 -- Implicit_With_From_Instantiation (Flag12-Sem)
1296 -- Set in N_With_Clause nodes from generic instantiations.
1298 -- Import_Interface_Present (Flag16-Sem)
1299 -- This flag is set in an Interface or Import pragma if a matching
1300 -- pragma of the other kind is also present. This is used to avoid
1301 -- generating some unwanted error messages.
1303 -- In_Assertion_Expression (Flag4-Sem)
1304 -- This flag is present in N_Function_Call nodes. It is set if the
1305 -- function is called from within an assertion expression. This is
1306 -- used to avoid some bogus warnings about early elaboration.
1308 -- Includes_Infinities (Flag11-Sem)
1309 -- This flag is present in N_Range nodes. It is set for the range of
1310 -- unconstrained float types defined in Standard, which include not only
1311 -- the given range of values, but also legitimately can include infinite
1312 -- values. This flag is false for any float type for which an explicit
1313 -- range is given by the programmer, even if that range is identical to
1314 -- the range for Float.
1316 -- Inherited_Discriminant (Flag13-Sem)
1317 -- This flag is present in N_Component_Association nodes. It indicates
1318 -- that a given component association in an extension aggregate is the
1319 -- value obtained from a constraint on an ancestor. Used to prevent
1320 -- double expansion when the aggregate has expansion delayed.
1322 -- Instance_Spec (Node5-Sem)
1323 -- This field is present in generic instantiation nodes, and also in
1324 -- formal package declaration nodes (formal package declarations are
1325 -- treated in a manner very similar to package instantiations). It points
1326 -- to the node for the spec of the instance, inserted as part of the
1327 -- semantic processing for instantiations in Sem_Ch12.
1329 -- Is_Accessibility_Actual (Flag13-Sem)
1330 -- Present in N_Parameter_Association nodes. True if the parameter is
1331 -- an extra actual that carries the accessibility level of the actual
1332 -- for an access parameter, in a function that dispatches on result and
1333 -- is called in a dispatching context. Used to prevent a formal/actual
1334 -- mismatch when the call is rewritten as a dispatching call.
1336 -- Is_Asynchronous_Call_Block (Flag7-Sem)
1337 -- A flag set in a Block_Statement node to indicate that it is the
1338 -- expansion of an asynchronous entry call. Such a block needs cleanup
1339 -- handler to assure that the call is cancelled.
1341 -- Is_Boolean_Aspect (Flag16-Sem)
1342 -- Present in N_Aspect_Specification node. Set if the aspect is for a
1343 -- boolean aspect (i.e. Aspect_Id is in Boolean_Aspect subtype).
1345 -- Is_Checked (Flag11-Sem)
1346 -- Present in N_Aspect_Specification and N_Pragma nodes. Set for an
1347 -- assertion aspect or pragma, or check pragma for an assertion, that
1348 -- is to be checked at run time. If either Is_Checked or Is_Ignored
1349 -- is set (they cannot both be set), then this means that the status of
1350 -- the pragma has been checked at the appropriate point and should not
1351 -- be further modified (in some cases these flags are copied when a
1352 -- pragma is rewritten).
1354 -- Is_Component_Left_Opnd (Flag13-Sem)
1355 -- Is_Component_Right_Opnd (Flag14-Sem)
1356 -- Present in concatenation nodes, to indicate that the corresponding
1357 -- operand is of the component type of the result. Used in resolving
1358 -- concatenation nodes in instances.
1360 -- Is_Delayed_Aspect (Flag14-Sem)
1361 -- Present in N_Pragma and N_Attribute_Definition_Clause nodes which
1362 -- come from aspect specifications, where the evaluation of the aspect
1363 -- must be delayed to the freeze point. This flag is also set True in
1364 -- the corresponding N_Aspect_Specification node.
1366 -- Is_Controlling_Actual (Flag16-Sem)
1367 -- This flag is set on in an expression that is a controlling argument in
1368 -- a dispatching call. It is off in all other cases. See Sem_Disp for
1369 -- details of its use.
1371 -- Is_Disabled (Flag15-Sem)
1372 -- A flag set in an N_Aspect_Specification or N_Pragma node if there was
1373 -- a Check_Policy or Assertion_Policy (or in the case of a Debug_Pragma)
1374 -- a Debug_Policy pragma that resulted in totally disabling the flagged
1375 -- aspect or policy as a result of using the GNAT-defined policy DISABLE.
1376 -- If this flag is set, the aspect or policy is not analyzed for semantic
1377 -- correctness, so any expressions etc will not be marked as analyzed.
1379 -- Is_Dynamic_Coextension (Flag18-Sem)
1380 -- Present in allocator nodes, to indicate that this is an allocator
1381 -- for an access discriminant of a dynamically allocated object. The
1382 -- coextension must be deallocated and finalized at the same time as
1383 -- the enclosing object.
1385 -- Is_Entry_Barrier_Function (Flag8-Sem)
1386 -- This flag is set in an N_Subprogram_Body node which is the expansion
1387 -- of an entry barrier from a protected entry body. It is used for the
1388 -- circuitry checking for incorrect use of Current_Task.
1390 -- Is_Expanded_Build_In_Place_Call (Flag11-Sem)
1391 -- This flag is set in an N_Function_Call node to indicate that the extra
1392 -- actuals to support a build-in-place style of call have been added to
1395 -- Is_Finalization_Wrapper (Flag9-Sem);
1396 -- This flag is present in N_Block_Statement nodes. It is set when the
1397 -- block acts as a wrapper of a handled construct which has controlled
1398 -- objects. The wrapper prevents interference between exception handlers
1399 -- and At_End handlers.
1401 -- Is_Ignored (Flag9-Sem)
1402 -- A flag set in an N_Aspect_Specification or N_Pragma node if there was
1403 -- a Check_Policy or Assertion_Policy (or in the case of a Debug_Pragma)
1404 -- a Debug_Policy pragma that specified a policy of IGNORE, DISABLE, or
1405 -- OFF, for the pragma/aspect. If there was a Policy pragma specifying
1406 -- a Policy of ON or CHECK, then this flag is reset. If no Policy pragma
1407 -- gives a policy for the aspect or pragma, then there are two cases. For
1408 -- an assertion aspect or pragma (one of the assertion kinds allowed in
1409 -- an Assertion_Policy pragma), then Is_Ignored is set if assertions are
1410 -- ignored because of the absence of a -gnata switch. For any other
1411 -- aspects or pragmas, the flag is off. If this flag is set, the
1412 -- aspect/pragma is fully analyzed and checked for other syntactic
1413 -- and semantic errors, but it does not have any semantic effect.
1415 -- Is_In_Discriminant_Check (Flag11-Sem)
1416 -- This flag is present in a selected component, and is used to indicate
1417 -- that the reference occurs within a discriminant check. The
1418 -- significance is that optimizations based on assuming that the
1419 -- discriminant check has a correct value cannot be performed in this
1420 -- case (or the discriminant check may be optimized away!)
1422 -- Is_Machine_Number (Flag11-Sem)
1423 -- This flag is set in an N_Real_Literal node to indicate that the value
1424 -- is a machine number. This avoids some unnecessary cases of converting
1425 -- real literals to machine numbers.
1427 -- Is_Null_Loop (Flag16-Sem)
1428 -- This flag is set in an N_Loop_Statement node if the corresponding loop
1429 -- can be determined to be null at compile time. This is used to remove
1430 -- the loop entirely at expansion time.
1432 -- Is_Overloaded (Flag5-Sem)
1433 -- A flag present in all expression nodes. Used temporarily during
1434 -- overloading determination. The setting of this flag is not relevant
1435 -- once overloading analysis is complete.
1437 -- Is_Power_Of_2_For_Shift (Flag13-Sem)
1438 -- A flag present only in N_Op_Expon nodes. It is set when the
1439 -- exponentiation is of the form 2 ** N, where the type of N is an
1440 -- unsigned integral subtype whose size does not exceed the size of
1441 -- Standard_Integer (i.e. a type that can be safely converted to
1442 -- Natural), and the exponentiation appears as the right operand of an
1443 -- integer multiplication or an integer division where the dividend is
1444 -- unsigned. It is also required that overflow checking is off for both
1445 -- the exponentiation and the multiply/divide node. If this set of
1446 -- conditions holds, and the flag is set, then the division or
1447 -- multiplication can be (and is) converted to a shift.
1449 -- Is_Prefixed_Call (Flag17-Sem)
1450 -- This flag is set in a selected component within a generic unit, if
1451 -- it resolves to a prefixed call to a primitive operation. The flag
1452 -- is used to prevent accidental overloadings in an instance, when a
1453 -- primitive operation and a private record component may be homographs.
1455 -- Is_Protected_Subprogram_Body (Flag7-Sem)
1456 -- A flag set in a Subprogram_Body block to indicate that it is the
1457 -- implementation of a protected subprogram. Such a body needs cleanup
1458 -- handler to make sure that the associated protected object is unlocked
1459 -- when the subprogram completes.
1461 -- Is_Static_Coextension (Flag14-Sem)
1462 -- Present in N_Allocator nodes. Set if the allocator is a coextension
1463 -- of an object allocated on the stack rather than the heap.
1465 -- Is_Static_Expression (Flag6-Sem)
1466 -- Indicates that an expression is a static expression (RM 4.9). See spec
1467 -- of package Sem_Eval for full details on the use of this flag.
1469 -- Is_Subprogram_Descriptor (Flag16-Sem)
1470 -- Present in N_Object_Declaration, and set only for the object
1471 -- declaration generated for a subprogram descriptor in fast exception
1472 -- mode. See Exp_Ch11 for details of use.
1474 -- Is_Task_Allocation_Block (Flag6-Sem)
1475 -- A flag set in a Block_Statement node to indicate that it is the
1476 -- expansion of a task allocator, or the allocator of an object
1477 -- containing tasks. Such a block requires a cleanup handler to call
1478 -- Expunge_Unactivated_Tasks to complete any tasks that have been
1479 -- allocated but not activated when the allocator completes abnormally.
1481 -- Is_Task_Master (Flag5-Sem)
1482 -- A flag set in a Subprogram_Body, Block_Statement or Task_Body node to
1483 -- indicate that the construct is a task master (i.e. has declared tasks
1484 -- or declares an access to a task type).
1486 -- Itype (Node1-Sem)
1487 -- Used in N_Itype_Reference node to reference an itype for which it is
1488 -- important to ensure that it is defined. See description of this node
1489 -- for further details.
1491 -- Kill_Range_Check (Flag11-Sem)
1492 -- Used in an N_Unchecked_Type_Conversion node to indicate that the
1493 -- result should not be subjected to range checks. This is used for the
1494 -- implementation of Normalize_Scalars.
1496 -- Label_Construct (Node2-Sem)
1497 -- Used in an N_Implicit_Label_Declaration node. Refers to an N_Label,
1498 -- N_Block_Statement or N_Loop_Statement node to which the label
1499 -- declaration applies. This attribute is used both in the compiler and
1500 -- in the implementation of ASIS queries. The field is left empty for the
1501 -- special labels generated as part of expanding raise statements with a
1502 -- local exception handler.
1504 -- Library_Unit (Node4-Sem)
1505 -- In a stub node, Library_Unit points to the compilation unit node of
1506 -- the corresponding subunit.
1508 -- In a with clause node, Library_Unit points to the spec of the with'ed
1511 -- In a compilation unit node, the usage depends on the unit type:
1513 -- For a library unit body, Library_Unit points to the compilation unit
1514 -- node of the corresponding spec, unless it's a subprogram body with
1515 -- Acts_As_Spec set, in which case it points to itself.
1517 -- For a spec, Library_Unit points to the compilation unit node of the
1518 -- corresponding body, if present. The body will be present if the spec
1519 -- is or contains generics that we needed to instantiate. Similarly, the
1520 -- body will be present if we needed it for inlining purposes. Thus, if
1521 -- we have a spec/body pair, both of which are present, they point to
1522 -- each other via Library_Unit.
1524 -- For a subunit, Library_Unit points to the compilation unit node of
1527 -- Note that this field is not used to hold the parent pointer for child
1528 -- unit (which might in any case need to use it for some other purpose as
1529 -- described above). Instead for a child unit, implicit with's are
1530 -- generated for all parents.
1532 -- Local_Raise_Statements (Elist1)
1533 -- This field is present in exception handler nodes. It is set to
1534 -- No_Elist in the normal case. If there is at least one raise statement
1535 -- which can potentially be handled as a local raise, then this field
1536 -- points to a list of raise nodes, which are calls to a routine to raise
1537 -- an exception. These are raise nodes which can be optimized into gotos
1538 -- if the handler turns out to meet the conditions which permit this
1539 -- transformation. Note that this does NOT include instances of the
1540 -- N_Raise_xxx_Error nodes since the transformation of these nodes is
1541 -- handled by the back end (using the N_Push/N_Pop mechanism).
1543 -- Loop_Actions (List2-Sem)
1544 -- A list present in Component_Association nodes in array aggregates.
1545 -- Used to collect actions that must be executed within the loop because
1546 -- they may need to be evaluated anew each time through.
1548 -- Limited_View_Installed (Flag18-Sem)
1549 -- Present in With_Clauses and in package specifications. If set on
1550 -- with_clause, it indicates that this clause has created the current
1551 -- limited view of the designated package. On a package specification, it
1552 -- indicates that the limited view has already been created because the
1553 -- package is mentioned in a limited_with_clause in the closure of the
1554 -- unit being compiled.
1556 -- Local_Raise_Not_OK (Flag7-Sem)
1557 -- Present in N_Exception_Handler nodes. Set if the handler contains
1558 -- a construct (reraise statement, or call to subprogram in package
1559 -- GNAT.Current_Exception) that makes the handler unsuitable as a target
1560 -- for a local raise (one that could otherwise be converted to a goto).
1562 -- Must_Be_Byte_Aligned (Flag14-Sem)
1563 -- This flag is present in N_Attribute_Reference nodes. It can be set
1564 -- only for the Address and Unrestricted_Access attributes. If set it
1565 -- means that the object for which the address/access is given must be on
1566 -- a byte (more accurately a storage unit) boundary. If necessary, a copy
1567 -- of the object is to be made before taking the address (this copy is in
1568 -- the current scope on the stack frame). This is used for certain cases
1569 -- of code generated by the expander that passes parameters by address.
1571 -- The reason the copy is not made by the front end is that the back end
1572 -- has more information about type layout and may be able to (but is not
1573 -- guaranteed to) prevent making unnecessary copies.
1575 -- Must_Not_Freeze (Flag8-Sem)
1576 -- A flag present in all expression nodes. Normally expressions cause
1577 -- freezing as described in the RM. If this flag is set, then this is
1578 -- inhibited. This is used by the analyzer and expander to label nodes
1579 -- that are created by semantic analysis or expansion and which must not
1580 -- cause freezing even though they normally would. This flag is also
1581 -- present in an N_Subtype_Indication node, since we also use these in
1582 -- calls to Freeze_Expression.
1584 -- Next_Entity (Node2-Sem)
1585 -- Present in defining identifiers, defining character literals and
1586 -- defining operator symbols (i.e. in all entities). The entities of a
1587 -- scope are chained, and this field is used as the forward pointer for
1588 -- this list. See Einfo for further details.
1590 -- Next_Exit_Statement (Node3-Sem)
1591 -- Present in N_Exit_Statement nodes. The exit statements for a loop are
1592 -- chained (in reverse order of appearance) from the First_Exit_Statement
1593 -- field of the E_Loop entity for the loop. Next_Exit_Statement points to
1594 -- the next entry on this chain (Empty = end of list).
1596 -- Next_Implicit_With (Node3-Sem)
1597 -- Present in N_With_Clause. Part of a chain of with_clauses generated
1598 -- in rtsfind to indicate implicit dependencies on predefined units. Used
1599 -- to prevent multiple with_clauses for the same unit in a given context.
1600 -- A postorder traversal of the tree whose nodes are units and whose
1601 -- links are with_clauses defines the order in which CodePeer must
1602 -- examine a compiled unit and its full context. This ordering ensures
1603 -- that any subprogram call is examined after the subprogram declaration
1606 -- Next_Named_Actual (Node4-Sem)
1607 -- Present in parameter association nodes. Set during semantic analysis
1608 -- to point to the next named parameter, where parameters are ordered by
1609 -- declaration order (as opposed to the actual order in the call, which
1610 -- may be different due to named associations). Not that this field
1611 -- points to the explicit actual parameter itself, not to the
1612 -- N_Parameter_Association node (its parent).
1614 -- Next_Pragma (Node1-Sem)
1615 -- Present in N_Pragma nodes. Used to create a linked list of pragma
1616 -- nodes. Currently used for two purposes:
1618 -- Create a list of linked Check_Policy pragmas. The head of this list
1619 -- is stored in Opt.Check_Policy_List (which has further details).
1621 -- Used by processing for Pre/Postcondition pragmas to store a list of
1622 -- pragmas associated with the spec of a subprogram (see Sem_Prag for
1625 -- Used by processing for pragma SPARK_Mode to store multiple pragmas
1626 -- the apply to the same construct. These are visible/private mode for
1627 -- a package spec and declarative/statement mode for package body.
1629 -- Next_Rep_Item (Node5-Sem)
1630 -- Present in pragma nodes, attribute definition nodes, enumeration rep
1631 -- clauses, record rep clauses, aspect specification nodes. Used to link
1632 -- representation items that apply to an entity. See full description of
1633 -- First_Rep_Item field in Einfo for further details.
1635 -- Next_Use_Clause (Node3-Sem)
1636 -- While use clauses are active during semantic processing, they are
1637 -- chained from the scope stack entry, using Next_Use_Clause as a link
1638 -- pointer, with Empty marking the end of the list. The head pointer is
1639 -- in the scope stack entry (First_Use_Clause). At the end of semantic
1640 -- processing (i.e. when Gigi sees the tree, the contents of this field
1641 -- is undefined and should not be read).
1643 -- No_Ctrl_Actions (Flag7-Sem)
1644 -- Present in N_Assignment_Statement to indicate that no finalize nor
1645 -- adjust should take place on this assignment even though the rhs is
1646 -- controlled. This is used in init procs and aggregate expansions where
1647 -- the generated assignments are more initialisations than real
1650 -- No_Elaboration_Check (Flag14-Sem)
1651 -- Present in N_Function_Call and N_Procedure_Call_Statement. Indicates
1652 -- that no elaboration check is needed on the call, because it appears in
1653 -- the context of a local Suppress pragma. This is used on calls within
1654 -- task bodies, where the actual elaboration checks are applied after
1655 -- analysis, when the local scope stack is not present.
1657 -- No_Entities_Ref_In_Spec (Flag8-Sem)
1658 -- Present in N_With_Clause nodes. Set if the with clause is on the
1659 -- package or subprogram spec where the main unit is the corresponding
1660 -- body, and no entities of the with'ed unit are referenced by the spec
1661 -- (an entity may still be referenced in the body, so this flag is used
1662 -- to generate the proper message (see Sem_Util.Check_Unused_Withs for
1665 -- No_Initialization (Flag13-Sem)
1666 -- Present in N_Object_Declaration and N_Allocator to indicate that the
1667 -- object must not be initialized (by Initialize or call to an init
1668 -- proc). This is needed for controlled aggregates. When the Object
1669 -- declaration has an expression, this flag means that this expression
1670 -- should not be taken into account (needed for in place initialization
1671 -- with aggregates, and for object with an address clause, which are
1672 -- initialized with an assignment at freeze time).
1674 -- No_Minimize_Eliminate (Flag17-Sem)
1675 -- This flag is present in membership operator nodes (N_In/N_Not_In).
1676 -- It is used to indicate that processing for extended overflow checking
1677 -- modes is not required (this is used to prevent infinite recursion).
1679 -- No_Truncation (Flag17-Sem)
1680 -- Present in N_Unchecked_Type_Conversion node. This flag has an effect
1681 -- only if the RM_Size of the source is greater than the RM_Size of the
1682 -- target for scalar operands. Normally in such a case we truncate some
1683 -- higher order bits of the source, and then sign/zero extend the result
1684 -- to form the output value. But if this flag is set, then we do not do
1685 -- any truncation, so for example, if an 8 bit input is converted to 5
1686 -- bit result which is in fact stored in 8 bits, then the high order
1687 -- three bits of the target result will be copied from the source. This
1688 -- is used for properly setting out of range values for use by pragmas
1689 -- Initialize_Scalars and Normalize_Scalars.
1691 -- Original_Discriminant (Node2-Sem)
1692 -- Present in identifiers. Used in references to discriminants that
1693 -- appear in generic units. Because the names of the discriminants may be
1694 -- different in an instance, we use this field to recover the position of
1695 -- the discriminant in the original type, and replace it with the
1696 -- discriminant at the same position in the instantiated type.
1698 -- Original_Entity (Node2-Sem)
1699 -- Present in numeric literals. Used to denote the named number that has
1700 -- been constant-folded into the given literal. If literal is from
1701 -- source, or the result of some other constant-folding operation, then
1702 -- Original_Entity is empty. This field is needed to handle properly
1703 -- named numbers in generic units, where the Associated_Node field
1704 -- interferes with the Entity field, making it impossible to preserve the
1705 -- original entity at the point of instantiation (ASIS problem).
1707 -- Others_Discrete_Choices (List1-Sem)
1708 -- When a case statement or variant is analyzed, the semantic checks
1709 -- determine the actual list of choices that correspond to an others
1710 -- choice. This list is materialized for later use by the expander and
1711 -- the Others_Discrete_Choices field of an N_Others_Choice node points to
1712 -- this materialized list of choices, which is in standard format for a
1713 -- list of discrete choices, except that of course it cannot contain an
1714 -- N_Others_Choice entry.
1716 -- Parameter_List_Truncated (Flag17-Sem)
1717 -- Present in N_Function_Call and N_Procedure_Call_Statement nodes. Set
1718 -- (for OpenVMS ports of GNAT only) if the parameter list is truncated as
1719 -- a result of a First_Optional_Parameter specification in an
1720 -- Import_Function, Import_Procedure, or Import_Valued_Procedure pragma.
1721 -- The truncation is done by the expander by removing trailing parameters
1722 -- from the argument list, in accordance with the set of rules allowing
1723 -- such parameter removal. In particular, parameters can be removed
1724 -- working from the end of the parameter list backwards up to and
1725 -- including the entry designated by First_Optional_Parameter in the
1726 -- Import pragma. Parameters can be removed if they are implicit and the
1727 -- default value is a known-at-compile-time value, including the use of
1728 -- the Null_Parameter attribute, or if explicit parameter values are
1729 -- present that match the corresponding defaults.
1731 -- Parent_Spec (Node4-Sem)
1732 -- For a library unit that is a child unit spec (package or subprogram
1733 -- declaration, generic declaration or instantiation, or library level
1734 -- rename, this field points to the compilation unit node for the parent
1735 -- package specification. This field is Empty for library bodies (the
1736 -- parent spec in this case can be found from the corresponding spec).
1738 -- Premature_Use (Node5-Sem)
1739 -- Present in N_Incomplete_Type_Declaration node. Used for improved
1740 -- error diagnostics: if there is a premature usage of an incomplete
1741 -- type, a subsequently generated error message indicates the position
1742 -- of its full declaration.
1744 -- Present_Expr (Uint3-Sem)
1745 -- Present in an N_Variant node. This has a meaningful value only after
1746 -- Gigi has back annotated the tree with representation information. At
1747 -- this point, it contains a reference to a gcc expression that depends
1748 -- on the values of one or more discriminants. Give a set of discriminant
1749 -- values, this expression evaluates to False (zero) if variant is not
1750 -- present, and True (non-zero) if it is present. See unit Repinfo for
1751 -- further details on gigi back annotation. This field is used during
1752 -- ASIS processing (data decomposition annex) to determine if a field is
1755 -- Print_In_Hex (Flag13-Sem)
1756 -- Set on an N_Integer_Literal node to indicate that the value should be
1757 -- printed in hexadecimal in the sprint listing. Has no effect on
1758 -- legality or semantics of program, only on the displayed output. This
1759 -- is used to clarify output from the packed array cases.
1761 -- Procedure_To_Call (Node2-Sem)
1762 -- Present in N_Allocator, N_Free_Statement, N_Simple_Return_Statement,
1763 -- and N_Extended_Return_Statement nodes. References the entity for the
1764 -- declaration of the procedure to be called to accomplish the required
1765 -- operation (i.e. for the Allocate procedure in the case of N_Allocator
1766 -- and N_Simple_Return_Statement and N_Extended_Return_Statement (for
1767 -- allocating the return value), and for the Deallocate procedure in the
1768 -- case of N_Free_Statement.
1770 -- Raises_Constraint_Error (Flag7-Sem)
1771 -- Set on an expression whose evaluation will definitely fail constraint
1772 -- error check. In the case of static expressions, this flag must be set
1773 -- accurately (and if it is set, the expression is typically illegal
1774 -- unless it appears as a non-elaborated branch of a short-circuit form).
1775 -- For a non-static expression, this flag may be set whenever an
1776 -- expression (e.g. an aggregate) is known to raise constraint error. If
1777 -- set, the expression definitely will raise CE if elaborated at runtime.
1778 -- If not set, the expression may or may not raise CE. In other words, on
1779 -- static expressions, the flag is set accurately, on non-static
1780 -- expressions it is set conservatively.
1782 -- Redundant_Use (Flag13-Sem)
1783 -- Present in nodes that can appear as an operand in a use clause or use
1784 -- type clause (identifiers, expanded names, attribute references). Set
1785 -- to indicate that a use is redundant (and therefore need not be undone
1788 -- Renaming_Exception (Node2-Sem)
1789 -- Present in N_Exception_Declaration node. Used to point back to the
1790 -- exception renaming for an exception declared within a subprogram.
1791 -- What happens is that an exception declared in a subprogram is moved
1792 -- to the library level with a unique name, and the original exception
1793 -- becomes a renaming. This link from the library level exception to the
1794 -- renaming declaration allows registering of the proper exception name.
1796 -- Return_Statement_Entity (Node5-Sem)
1797 -- Present in N_Simple_Return_Statement and N_Extended_Return_Statement.
1798 -- Points to an E_Return_Statement representing the return statement.
1800 -- Return_Object_Declarations (List3)
1801 -- Present in N_Extended_Return_Statement. Points to a list initially
1802 -- containing a single N_Object_Declaration representing the return
1803 -- object. We use a list (instead of just a pointer to the object decl)
1804 -- because Analyze wants to insert extra actions on this list.
1806 -- Rounded_Result (Flag18-Sem)
1807 -- Present in N_Type_Conversion, N_Op_Divide and N_Op_Multiply nodes.
1808 -- Used in the fixed-point cases to indicate that the result must be
1809 -- rounded as a result of the use of the 'Round attribute. Also used for
1810 -- integer N_Op_Divide nodes to indicate that the result should be
1811 -- rounded to the nearest integer (breaking ties away from zero), rather
1812 -- than truncated towards zero as usual. These rounded integer operations
1813 -- are the result of expansion of rounded fixed-point divide, conversion
1814 -- and multiplication operations.
1816 -- SCIL_Entity (Node4-Sem)
1817 -- Present in SCIL nodes. Used to reference the tagged type associated
1818 -- with the SCIL node.
1820 -- SCIL_Controlling_Tag (Node5-Sem)
1821 -- Present in N_SCIL_Dispatching_Call nodes. Used to reference the
1822 -- controlling tag of a dispatching call.
1824 -- SCIL_Tag_Value (Node5-Sem)
1825 -- Present in N_SCIL_Membership_Test nodes. Used to reference the tag
1826 -- value that is being tested.
1828 -- SCIL_Target_Prim (Node2-Sem)
1829 -- Present in N_SCIL_Dispatching_Call nodes. Used to reference the tagged
1830 -- type primitive associated with the SCIL node.
1832 -- Scope (Node3-Sem)
1833 -- Present in defining identifiers, defining character literals and
1834 -- defining operator symbols (i.e. in all entities). The entities of a
1835 -- scope all use this field to reference the corresponding scope entity.
1836 -- See Einfo for further details.
1838 -- Shift_Count_OK (Flag4-Sem)
1839 -- A flag present in shift nodes to indicate that the shift count is
1840 -- known to be in range, i.e. is in the range from zero to word length
1841 -- minus one. If this flag is not set, then the shift count may be
1842 -- outside this range, i.e. larger than the word length, and the code
1843 -- must ensure that such shift counts give the appropriate result.
1845 -- Source_Type (Node1-Sem)
1846 -- Used in an N_Validate_Unchecked_Conversion node to point to the
1847 -- source type entity for the unchecked conversion instantiation
1848 -- which gigi must do size validation for.
1850 -- Split_PPC (Flag17)
1851 -- When a Pre or Post aspect specification is processed, it is broken
1852 -- into AND THEN sections. The left most section has Split_PPC set to
1853 -- False, indicating that it is the original specification (e.g. for
1854 -- posting errors). For other sections, Split_PPC is set to True.
1855 -- This flag is set in both the N_Aspect_Specification node itself,
1856 -- and in the pragma which is generated from this node.
1858 -- Storage_Pool (Node1-Sem)
1859 -- Present in N_Allocator, N_Free_Statement, N_Simple_Return_Statement,
1860 -- and N_Extended_Return_Statement nodes. References the entity for the
1861 -- storage pool to be used for the allocate or free call or for the
1862 -- allocation of the returned value from function. Empty indicates that
1863 -- the global default pool is to be used. Note that in the case
1864 -- of a return statement, this field is set only if the function returns
1865 -- value of a type whose size is not known at compile time on the
1868 -- Suppress_Assignment_Checks (Flag18-Sem)
1869 -- Used in generated N_Assignment_Statement nodes to suppress predicate
1870 -- and range checks in cases where the generated code knows that the
1871 -- value being assigned is in range and satisfies any predicate. Also
1872 -- can be set in N_Object_Declaration nodes, to similarly suppress any
1873 -- checks on the initializing value.
1875 -- Suppress_Loop_Warnings (Flag17-Sem)
1876 -- Used in N_Loop_Statement node to indicate that warnings within the
1877 -- body of the loop should be suppressed. This is set when the range
1878 -- of a FOR loop is known to be null, or is probably null (loop would
1879 -- only execute if invalid values are present).
1881 -- Target_Type (Node2-Sem)
1882 -- Used in an N_Validate_Unchecked_Conversion node to point to the target
1883 -- type entity for the unchecked conversion instantiation which gigi must
1884 -- do size validation for.
1886 -- Then_Actions (List3-Sem)
1887 -- This field is present in if expression nodes. During code expansion
1888 -- we use the Insert_Actions procedure (in Exp_Util) to insert actions
1889 -- at an appropriate place in the tree to get elaborated at the right
1890 -- time. For if expressions, we have to be sure that the actions for
1891 -- for the Then branch are only elaborated if the condition is True.
1892 -- The Then_Actions field is used as a temporary parking place for
1893 -- these actions. The final tree is always rewritten to eliminate the
1894 -- need for this field, so in the tree passed to Gigi, this field is
1895 -- always set to No_List.
1897 -- Treat_Fixed_As_Integer (Flag14-Sem)
1898 -- This flag appears in operator nodes for divide, multiply, mod and rem
1899 -- on fixed-point operands. It indicates that the operands are to be
1900 -- treated as integer values, ignoring small values. This flag is only
1901 -- set as a result of expansion of fixed-point operations. Typically a
1902 -- fixed-point multiplication in the source generates subsidiary
1903 -- multiplication and division operations that work with the underlying
1904 -- integer values and have this flag set. Note that this flag is not
1905 -- needed on other arithmetic operations (add, neg, subtract etc.) since
1906 -- in these cases it is always the case that fixed is treated as integer.
1907 -- The Etype field MUST be set if this flag is set. The analyzer knows to
1908 -- leave such nodes alone, and whoever makes them must set the correct
1911 -- TSS_Elist (Elist3-Sem)
1912 -- Present in N_Freeze_Entity nodes. Holds an element list containing
1913 -- entries for each TSS (type support subprogram) associated with the
1914 -- frozen type. The elements of the list are the entities for the
1915 -- subprograms (see package Exp_TSS for further details). Set to No_Elist
1916 -- if there are no type support subprograms for the type or if the freeze
1917 -- node is not for a type.
1919 -- Unreferenced_In_Spec (Flag7-Sem)
1920 -- Present in N_With_Clause nodes. Set if the with clause is on the
1921 -- package or subprogram spec where the main unit is the corresponding
1922 -- body, and is not referenced by the spec (it may still be referenced by
1923 -- the body, so this flag is used to generate the proper message (see
1924 -- Sem_Util.Check_Unused_Withs for details)
1926 -- Used_Operations (Elist5-Sem)
1927 -- Present in N_Use_Type_Clause nodes. Holds the list of operations that
1928 -- are made potentially use-visible by the clause. Simplifies processing
1929 -- on exit from the scope of the use_type_clause, in particular in the
1930 -- case of Use_All_Type, when those operations several scopes.
1932 -- Was_Originally_Stub (Flag13-Sem)
1933 -- This flag is set in the node for a proper body that replaces stub.
1934 -- During the analysis procedure, stubs in some situations get rewritten
1935 -- by the corresponding bodies, and we set this flag to remember that
1936 -- this happened. Note that it is not good enough to rely on the use of
1937 -- Original_Node here because of the case of nested instantiations where
1938 -- the substituted node can be copied.
1940 -- Withed_Body (Node1-Sem)
1941 -- Present in N_With_Clause nodes. Set if the unit in whose context
1942 -- the with_clause appears instantiates a generic contained in the
1943 -- library unit of the with_clause and as a result loads its body.
1944 -- Used for a more precise unit traversal for CodePeer.

1965 -- If Statement end if;
1966 -- Case Statement end case;
1968 -- Record Definition end record;
1969 -- Enumeration Definition );
1971 -- The End_Label and End_Span fields are used to mark the locations of
1972 -- these lines, and also keep track of the label in the case where a label
1975 -- For the first group above, the End_Label field of the corresponding node
1976 -- is used to point to the label identifier. In the case where there is no
1977 -- label in the source, the parser supplies a dummy identifier (with
1978 -- Comes_From_Source set to False), and the Sloc of this dummy identifier
1979 -- marks the location of the token following the END token.
1981 -- For the second group, the use of End_Label is similar, but the End_Label
1982 -- is found in the N_Handled_Sequence_Of_Statements node. This is done
1983 -- simply because in some cases there is no room in the parent node.
1985 -- For the third group, there is never any label, and instead of using
1986 -- End_Label, we use the End_Span field which gives the location of the
1987 -- token following END, relative to the starting Sloc of the construct,
1988 -- i.e. add Sloc (Node) + End_Span (Node) to get the Sloc of the IF or CASE
1989 -- following the End_Label.
1991 -- The record definition case is handled specially, we treat it as though
1992 -- it required an optional label which is never present, and so the parser
1993 -- always builds a dummy identifier with Comes From Source set False. The
1994 -- reason we do this, rather than using End_Span in this case, is that we
1995 -- want to generate a cross-ref entry for the end of a record, since it
1996 -- represents a scope for name declaration purposes.
1998 -- The enumeration definition case is handled in an exactly similar manner,
1999 -- building a dummy identifier to get a cross-reference.
2001 -- Note: the reason we store the difference as a Uint, instead of storing
2002 -- the Source_Ptr value directly, is that Source_Ptr values cannot be
2003 -- distinguished from other types of values, and we count on all general
2004 -- use fields being self describing. To make things easier for clients,
2005 -- note that we provide function End_Location, and procedure
2006 -- Set_End_Location to allow access to the logical value (which is the

3419 -- Note: the syntax is quite ambiguous at this point. Consider:
3421 -- A'Length (X) X is part of the attribute designator
3422 -- A'Pos (X) X is an explicit actual parameter of function A'Pos
3423 -- A'Class (X) X is the expression of a type conversion
3425 -- It would be possible for the parser to distinguish these cases
3426 -- by looking at the attribute identifier. However, that would mean
3427 -- more work in introducing new implementation defined attributes,
3428 -- and also it would mean that special processing for attributes
3429 -- would be scattered around, instead of being centralized in the
3430 -- semantic routine that handles an N_Attribute_Reference node.
3431 -- Consequently, the parser in all the above cases stores the
3432 -- expression (X in these examples) as a single element list in
3433 -- in the Expressions field of the N_Attribute_Reference node.
3435 -- Similarly, for attributes like Max which take two arguments,
3436 -- we store the two arguments as a two element list in the
3437 -- Expressions field. Of course it is clear at parse time that
3438 -- this case is really a function call with an attribute as the
3439 -- prefix, but it turns out to be convenient to handle the two
3440 -- argument case in a similar manner to the one argument case,
3441 -- and indeed in general the parser will accept any number of
3442 -- expressions in this position and store them as a list in the
3443 -- attribute reference node. This allows for future addition of
3444 -- attributes that take more than two arguments.
3446 -- Note: named associates are not permitted in function calls where
3447 -- the function is an attribute (see RM 6.4(3)) so it is legitimate
3448 -- to skip the normal subprogram argument processing.
3450 -- Note: for the attributes whose designators are technically keywords,
3451 -- i.e. digits, access, delta, range, the Attribute_Name field contains
3452 -- the corresponding name, even though no identifier is involved.
3454 -- Note: the generated code may contain stream attributes applied to
3455 -- limited types for which no stream routines exist officially. In such
3456 -- case, the result is to use the stream attribute for the underlying
3457 -- full type, or in the case of a protected type, the components
3458 -- (including any discriminants) are merely streamed in order.
3460 -- See Exp_Attr for a complete description of which attributes are
3461 -- passed onto Gigi, and which are handled entirely by the front end.
3463 -- Gigi restriction: For the Pos attribute, the prefix cannot be
3464 -- a non-standard enumeration type or a nonzero/zero semantics
3465 -- boolean type, so the value is simply the stored representation.
3467 -- Gigi requirement: For the Mechanism_Code attribute, if the prefix
3468 -- references a subprogram that is a renaming, then the front end must
3469 -- rewrite the attribute to refer directly to the renamed entity.
3471 -- Note: In generated code, the Address and Unrestricted_Access
3472 -- attributes can be applied to any expression, and the meaning is
3473 -- to create an object containing the value (the object is in the
3474 -- current stack frame), and pass the address of this value. If the
3475 -- Must_Be_Byte_Aligned flag is set, then the object whose address
3476 -- is taken must be on a byte (storage unit) boundary, and if it is

3755 -- The parentheses are recorded by keeping a Paren_Count field in every

3763 -- but we do not need to lose sleep over this.
3765 -- Historical note: in versions of GNAT prior to 1.75, there was a node
3766 -- type N_Parenthesized_Expression used to accurately record unlimited
3767 -- numbers of levels of parentheses. However, it turned out to be a
3768 -- real nuisance to have to take into account the possible presence of
3769 -- this node during semantic analysis, since basically parentheses have
3770 -- zero relevance to semantic analysis.
3772 -- Note: the level of parentheses always present in things like

5908 -- However, there are two additional items not reflected in the above
5909 -- syntax. First we have the global declarations that are added by the
5910 -- code generator. These are outer level declarations (so they cannot
5911 -- be represented as being inside the units). An example is the wrapper
5912 -- subprograms that are created to do ABE checking. As always a list of
5913 -- declarations can contain actions as well (i.e. statements), and such
5914 -- statements are executed as part of the elaboration of the unit. Note
5915 -- that all such declarations are elaborated before the library unit.
5917 -- Similarly, certain actions need to be elaborated at the completion
5918 -- of elaboration of the library unit (notably the statement that sets
5919 -- the Boolean flag indicating that elaboration is complete).
5921 -- The third item not reflected in the syntax is pragmas that appear
5922 -- after the compilation unit. As always pragmas are a problem since
5923 -- they are not part of the formal syntax, but can be stuck into the
5924 -- source following a set of ad hoc rules, and we have to find an ad
5925 -- hoc way of sticking them into the tree. For pragmas that appear
5926 -- before the library unit, we just consider them to be part of the
5927 -- context clause, and pragmas can appear in the Context_Items list
5928 -- of the compilation unit. However, pragmas can also appear after
5929 -- the library item.

6193 -- used only internally currently, but is considered to be syntactic.
6194 -- At the moment, the only cleanup action allowed is a single call to
6195 -- a parameterless procedure, and the Identifier field of the node is
6196 -- the procedure to be called. The cleanup action occurs whenever the
6197 -- sequence of statements is left for any reason. The possible reasons
6199 -- 1. reaching the end of the sequence
6200 -- 2. exit, return, or goto
6201 -- 3. exception or abort
6202 -- For some back ends, such as gcc with ZCX, "at end" is implemented
6203 -- entirely in the back end. In this case, a handled sequence of
6204 -- statements with an "at end" cannot also have exception handlers.
6205 -- For other back ends, such as gcc with SJLJ and .NET, the
6206 -- implementation is split between the front end and back end; the front
6207 -- end implements 3, and the back end implements 1 and 2. In this case,
6208 -- if there is an "at end", the front end inserts the appropriate
6209 -- exception handler, and this handler takes precedence over "at end"
6210 -- in case of exception.
6212 -- The inserted exception handler is of the form:
6214 -- when all others =>
6218 -- where cleanup is the procedure to be called. The reason we do this is
6219 -- so that the front end can handle the necessary entries in the
6220 -- exception tables, and other exception handler actions required as
6221 -- part of the normal handling for exception handlers.
6223 -- The AT END cleanup handler protects only the sequence of statements
6224 -- (not the associated declarations of the parent), just like exception
6225 -- handlers. The big difference is that the cleanup procedure is called
6226 -- on either a normal or an abnormal exit from the statement sequence.
6228 -- Note: the list of Exception_Handlers can contain pragmas as well

7237 -- Expression with Actions --
7238 -----------------------------
7240 -- This node is created by the analyzer/expander to handle some
7241 -- expansion cases, notably short circuit forms where there are
7242 -- actions associated with the right-hand side operand.
7244 -- The N_Expression_With_Actions node represents an expression with
7245 -- an associated set of actions (which are executable statements and
7246 -- declarations, as might occur in a handled statement sequence).
7248 -- The required semantics is that the set of actions is executed in
7249 -- the order in which it appears just before the expression is
7250 -- evaluated (and these actions must only be executed if the value
7251 -- of the expression is evaluated). The node is considered to be
7252 -- a subexpression, whose value is the value of the Expression after
7253 -- executing all the actions.
7255 -- If the actions contain declarations, then these declarations may
7256 -- be referenced within the expression. However note that there is
7257 -- no proper scope associated with the expression-with-action, so the
7258 -- back-end will elaborate them in the context of the enclosing scope.

7275 -- Note: Expression may be a Null_Statement, in which case the
7276 -- N_Expression_With_Actions has type Standard_Void_Type. However some
7277 -- backends do not support such expression-with-actions occurring
7278 -- outside of a proper (non-void) expression, so this should just be
7279 -- used as an intermediate representation within the front-end. Also
7280 -- note that this is really an irregularity (expressions and statements
7281 -- are not interchangeable, and in particular an N_Null_Statement is
7282 -- not a proper expression), and in the long term all cases of this
7283 -- idiom should instead use a new node kind N_Compound_Statement.

7286 -- Free Statement --
7287 --------------------

7309 -- This node marks the point in a declarative part at which an entity
7310 -- declared therein becomes frozen. The expander places initialization
7311 -- procedures for types at those points. Gigi uses the freezing point
7312 -- to elaborate entities that may depend on previous private types.
7314 -- See the section in Einfo "Delayed Freezing and Elaboration" for

7321 -- generated by the expander which are associated with the freeze

7358 -- For entities declared within a generic unit, for which no code is

7372 -- Implicit Label Declaration --
7373 --------------------------------
7375 -- An implicit label declaration is created for every occurrence of a
7376 -- label on a statement or a label on a block or loop. It is chained
7377 -- in the declarations of the innermost enclosing block as specified
7378 -- in RM section 5.1 (3).
7380 -- The Defining_Identifier is the actual identifier for the statement
7381 -- identifier. Note that the occurrence of the label is a reference, NOT
7382 -- the defining occurrence. The defining occurrence occurs at the head
7383 -- of the innermost enclosing block, and is represented by this node.
7385 -- Note: from the grammar, this might better be called an implicit
7386 -- statement identifier declaration, but the term we choose seems
7387 -- friendlier, since at least informally statement identifiers are
7388 -- called labels in both cases (i.e. when used in labels, and when
7389 -- used as the identifiers of blocks and loops).
7391 -- Note: although this is logically a semantic node, since it does not
7392 -- correspond directly to a source syntax construction, these nodes are

7414 -- A typical use of this node is when an Itype is to be referenced in
7415 -- two branches of an IF statement. In this case it is important that
7416 -- the first use of the Itype not be inside the conditional, since then
7417 -- it might not be defined if the other branch of the IF is taken, in

7433 ---------------------
7435 -- One of these nodes is created during semantic analysis to replace
7436 -- a node for an expression that is determined to definitely raise
7437 -- the corresponding exception.
7439 -- The N_Raise_xxx_Error node may also stand alone in place
7440 -- of a declaration or statement, in which case it simply causes
7441 -- the exception to be raised (i.e. it is equivalent to a raise
7442 -- statement that raises the corresponding exception). This use
7443 -- is distinguished by the fact that the Etype in this case is
7444 -- Standard_Void_Type; in the subexpression case, the Etype is the
7445 -- same as the type of the subexpression which it replaces.
7447 -- If Condition is empty, then the raise is unconditional. If the
7448 -- Condition field is non-empty, it is a boolean expression which
7449 -- is first evaluated, and the exception is raised only if the
7450 -- value of the expression is True. In the unconditional case, the
7451 -- creation of this node is usually accompanied by a warning message
7452 -- error. The creation of this node will usually be accompanied by a
7453 -- message (unless it appears within the right operand of a short
7454 -- circuit form whose left argument is static and decisively

7513 -- 2. Exceptions from checks triggered by Do_xxx_Check flags
7514 -- 3. Other cases not specifically marked by the front end
7516 -- Normally all such exceptions are translated into calls to the proper
7517 -- Rcheck_xx procedure, where xx encodes both the exception to be raised
7518 -- and the exception message.
7520 -- The front end may determine that for a particular sequence of code,
7521 -- exceptions in any of these three categories for a particular builtin
7522 -- exception should result in a goto, rather than a call to Rcheck_xx.
7523 -- The exact sequence to be generated is:
7525 -- Local_Raise (exception'Identity);
7528 -- The front end marks such a sequence of code by bracketing it with
7529 -- push and pop nodes:
7531 -- N_Push_xxx_Label (referencing the label)
7533 -- (code where transformation is expected for exception xxx)
7537 -- The use of push/pop reflects the fact that such regions can properly
7538 -- nest, and one special case is a subregion in which no transformation

7569 -- An example is the construction of the parameter block passed to a
7570 -- task entry. The N_Reference node is provided for this purpose. It is
7571 -- similar in effect to the use of the Unrestricted_Access attribute,
7572 -- and like Unrestricted_Access can be applied to objects which would
7573 -- not be valid prefixes for the Unchecked_Access attribute (e.g.
7574 -- objects which are not aliased, and slices). In addition it can be
7575 -- applied to composite type values as well as objects, including string
