2004-02-02  Olivier Hainque  <hainque@act-europe.fr>

	* init.c (__gnat_install_handler): Setup an alternate stack for signal
	handlers in the environment thread. This allows proper propagation of
	an exception on stack overflows in this thread even when the builtin
	ABI stack-checking scheme is used without support for a stack reserve
	region.

	* utils.c (create_field_decl): Augment the head comment about bitfield
	creation, and don't account for DECL_BIT_FIELD in DECL_NONADDRESSABLE_P
	here, because the former is not accurate enough at this point.
	Let finish_record_type decide instead.
	Don't make a bitfield if the field is to be addressable.
	Always set a size for the field if the record is packed, to ensure the
	checks for bitfield creation are triggered.
	(finish_record_type): During last pass over the fields, clear
	DECL_BIT_FIELD when possible in the !STRICT_ALIGNMENT case, as this is
	not covered by the calls to layout_decl.  Adjust DECL_NONADDRESSABLE_P
	from DECL_BIT_FIELD.

package Atree is
-- This package defines the format of the tree used to represent the Ada
-- program internally. Syntactic and semantic information is combined in
-- this tree. There is no separate symbol table structure.
-- WARNING: There is a C version of this package. Any changes to this
-- source file must be properly reflected in the C header file tree.h
-- Package Atree defines the basic structure of the tree and its nodes and
-- provides the basic abstract interface for manipulating the tree. Two
-- other packages use this interface to define the representation of Ada
-- programs using this tree format. The package Sinfo defines the basic
-- representation of the syntactic structure of the program, as output
-- by the parser. The package Entity_Info defines the semantic information
-- which is added to the tree nodes that represent declared entities (i.e.
-- the information which might typically be described in a separate symbol
-- table structure.
-- The front end of the compiler first parses the program and generates a
-- tree that is simply a syntactic representation of the program in abstract
-- syntax tree format. Subsequent processing in the front end traverses the
-- tree, transforming it in various ways and adding semantic information.
----------------------------------------
-- Definitions of Fields in Tree Node --
----------------------------------------
-- The representation of the tree is completely hidden, using a functional
-- interface for accessing and modifying the contents of nodes. Logically
-- a node contains a number of fields, much as though the nodes were
-- defined as a record type. The fields in a node are as follows:
-- Nkind Indicates the kind of the node. This field is present
-- in all nodes. The type is Node_Kind, which is declared
-- in the package Sinfo.
-- Sloc Location (Source_Ptr) of the corresponding token
-- in the Source buffer. The individual node definitions
-- show which token is referenced by this pointer.
-- In_List A flag used to indicate if the node is a member
-- of a node list.
-- Rewrite_Sub A flag set if the node has been rewritten using
-- the Rewrite procedure. The original value of the
-- node is retrievable with Original_Node.
-- Rewrite_Ins A flag set if a node is marked as a rewrite inserted
-- node as a result of a call to Mark_Rewrite_Insertion.
-- Paren_Count A 2-bit count used on expression nodes to indicate
-- the level of parentheses. Up to 3 levels can be
-- accomodated. Anything more than 3 levels is treated
-- as 3 levels (conformance tests that complain about
-- this are hereby deemed pathological!) Set to zero
-- for non-subexpression nodes.
-- Comes_From_Source
-- This flag is present in all nodes. It is set if the
-- node is built by the scanner or parser, and clear if
-- the node is built by the analyzer or expander. It
-- indicates that the node corresponds to a construct
-- that appears in the original source program.
-- Analyzed This flag is present in all nodes. It is set when
-- a node is analyzed, and is used to avoid analyzing
-- the same node twice. Analysis includes expansion if
-- expansion is active, so in this case if the flag is
-- set it means the node has been analyzed and expanded.
-- Error_Posted This flag is present in all nodes. It is set when
-- an error message is posted which is associated with
-- the flagged node. This is used to avoid posting more
-- than one message on the same node.
-- Field1
-- Field2
-- Field3
-- Field4
-- Field5 Five fields holding Union_Id values
-- Char_CodeN Synonym for FieldN typed as Char_Code
-- ElistN Synonym for FieldN typed as Elist_Id
-- ListN Synonym for FieldN typed as List_Id
-- NameN Synonym for FieldN typed as Name_Id
-- NodeN Synonym for FieldN typed as Node_Id
-- StrN Synonym for FieldN typed as String_Id
-- UintN Synonym for FieldN typed as Uint (Empty = Uint_0)
-- UrealN Synonym for FieldN typed as Ureal
-- Note: the actual usage of FieldN (i.e. whether it contains a Char_Code,
-- Elist_Id, List_Id, Name_Id, Node_Id, String_Id, Uint or Ureal), depends
-- on the value in Nkind. Generally the access to this field is always via
-- the functional interface, so the field names Char_CodeN, ElistN, ListN,
-- NameN, NodeN, StrN, UintN and UrealN are used only in the bodies of the
-- access functions (i.e. in the bodies of Sinfo and Einfo). These access
-- functions contain debugging code that checks that the use is consistent
-- with Nkind and Ekind values.
-- However, in specialized circumstances (examples are the circuit in
-- generic instantiation to copy trees, and in the tree dump routine),
-- it is useful to be able to do untyped traversals, and an internal
-- package in Atree allows for direct untyped accesses in such cases.
-- Flag4 Fifteen Boolean flags (use depends on Nkind and
-- Flag5 Ekind, as described for FieldN). Again the access
-- Flag6 is usually via subprograms in Sinfo and Einfo which
-- Flag7 provide high-level synonyms for these flags, and
-- Flag8 contain debugging code that checks that the values
-- Flag9 in Nkind and Ekind are appropriate for the access.
-- Flag10
-- Flag11 Note that Flag1-3 are missing from this list. The
-- Flag12 first three flag positions are reserved for the
-- Flag13 standard flags (Comes_From_Source, Error_Posted,
-- Flag14 and Analyzed)
-- Flag15
-- Flag16
-- Flag17
-- Flag18
-- Link For a node, points to the Parent. For a list, points
-- to the list header. Note that in the latter case, a
-- client cannot modify the link field. This field is
-- private to the Atree package (but is also modified
-- by the Nlists package).
-- The following additional fields are present in extended nodes used
-- for entities (Nkind in N_Entity).
-- Ekind Entity type. This field indicates the type of the
-- entity, it is of type Entity_Kind which is defined
-- in package Einfo.
-- Flag19 133 additional flags
-- ...
-- Flag151
-- Convention Entity convention (Convention_Id value)
-- Field6 Additional Union_Id value stored in tree
-- Node6 Synonym for Field6 typed as Node_Id
-- Elist6 Synonym for Field6 typed as Elist_Id
-- Uint6 Synonym for Field6 typed as Uint (Empty = Uint_0)
-- Similar definitions for Field7 to Field23 (and Node7-Node23,
-- Elist7-Elist23, Uint7-Uint23, Ureal7-Ureal23). Note that not all
-- these functions are defined, only the ones that are actually used.
type Paren_Count_Type is mod 4;
for Paren_Count_Type'Size use 2;
-- Type used for Paren_Count field
function Last_Node_Id return Node_Id;
pragma Inline (Last_Node_Id);
-- Returns Id of last allocated node Id
function Nodes_Address return System.Address;
-- Return address of Nodes table (used in Back_End for Gigi call)
function Num_Nodes return Nat;
-- Total number of nodes allocated, where an entity counts as a single
-- node. This count is incremented every time a node or entity is
-- allocated, and decremented every time a node or entity is deleted.
-- This value is used by Xref and by Treepr to allocate hash tables of
-- suitable size for hashing Node_Id values.
-----------------------
-- Use of Empty Node --
-----------------------
-- The special Node_Id Empty is used to mark missing fields. Whenever the
-- syntax has an optional component, then the corresponding field will be
-- set to Empty if the component is missing.
-- Note: Empty is not used to describe an empty list. Instead in this
-- case the node field contains a list which is empty, and these cases
-- should be distinguished (essentially from a type point of view, Empty
-- is a Node, and is thus not a list).
-- Note: Empty does in fact correspond to an allocated node. Only the
-- Nkind field of this node may be referenced. It contains N_Empty, which
-- uniquely identifies the empty case. This allows the Nkind field to be
-- dereferenced before the check for Empty which is sometimes useful.
-----------------------
-- Use of Error Node --
-----------------------
-- The Error node is used during syntactic and semantic analysis to
-- indicate that the corresponding piece of syntactic structure or
-- semantic meaning cannot properly be represented in the tree because
-- of an illegality in the program.
-- If an Error node is encountered, then you know that a previous
-- illegality has been detected. The proper reaction should be to
-- avoid posting related cascaded error messages, and to propagate
-- the error node if necessary.
------------------------
-- Current_Error_Node --
------------------------
-- The current error node is a global location indicating the current
-- node that is being processed for the purposes of placing a compiler
-- abort message. This is not necessarily perfectly accurate, it is
-- just a reasonably accurate best guess. It is used to output the
-- source location in the abort message by Comperr, and also to
-- implement the d3 debugging flag. This is also used by Rtsfind
-- to generate error messages for high integrity mode.
-- There are two ways this gets set. During parsing, when new source
-- nodes are being constructed by calls to New_Node and New_Entity,
-- either one of these calls sets Current_Error_Node to the newly
-- created node. During semantic analysis, this mechanism is not
-- used, and instead Current_Error_Node is set by the subprograms in
-- Debug_A that mark the start and end of analysis/expansion of a
-- node in the tree.
Current_Error_Node : Node_Id;
-- Node to place error messages
-------------------------------
-- Default Setting of Fields --
-------------------------------
-- Nkind is set to N_Unused_At_Start
-- Ekind is set to E_Void
-- Sloc is always set, there is no default value
-- Field1-5 fields are set to Empty
-- Field6-22 fields in extended nodes are set to Empty
-- Parent is set to Empty
-- All Boolean flag fields are set to False
-- Note: the value Empty is used in Field1-Field17 to indicate a null node.
-- The usage varies. The common uses are to indicate absence of an
-- optional clause or a completely unused Field1-17 field.
-------------------------------------
-- Use of Synonyms for Node Fields --
-------------------------------------
-- A subpackage Atree.Unchecked_Access provides routines for reading and
-- writing the fields defined above (Field1-17, Node1-17, Flag1-88 etc).
-- These unchecked access routines can be used for untyped traversals.
-- In addition they are used in the implementations of the Sinfo and
-- Einfo packages. These packages both provide logical synonyms for
-- the generic fields, together with an appropriate set of access routines.
-- Normally access to information within tree nodes uses these synonyms,
-- providing a high level typed interface to the tree information.
--------------------------------------------------
-- Node Allocation and Modification Subprograms --
--------------------------------------------------
-- Generally the parser builds the tree and then it is further decorated
-- (e.g. by setting the entity fields), but not fundamentally modified.
-- However, there are cases in which the tree must be restructured by
-- adding and rearranging nodes, as a result of disambiguating cases
-- which the parser could not parse correctly, and adding additional
-- semantic information (e.g. making constraint checks explicit). The
-- following subprograms are used for constructing the tree in the first
-- place, and then for subsequent modifications as required
procedure Initialize;
-- Called at the start of compilation to initialize the allocation of
-- the node and list tables and make the standard entries for Empty,
-- Error and Error_List. Note that Initialize must not be called if
-- Tree_Read is used.
procedure Lock;
-- Called before the backend is invoked to lock the nodes table
procedure Tree_Read;
-- Initializes internal tables from current tree file using Tree_Read.
-- Note that Initialize should not be called if Tree_Read is used.
-- Tree_Read includes all necessary initialization.
procedure Tree_Write;
-- Writes out internal tables to current tree file using Tree_Write
function New_Node
(New_Node_Kind : Node_Kind;
New_Sloc : Source_Ptr)
return Node_Id;
-- Allocates a completely new node with the given node type and source
-- location values. All other fields are set to their standard defaults:
--
-- Empty for all FieldN fields
-- False for all FlagN fields
--
-- The usual approach is to build a new node using this function and
-- then, using the value returned, use the Set_xxx functions to set
-- fields of the node as required. New_Node can only be used for
-- non-entity nodes, i.e. it never generates an extended node.
--
-- If we are currently parsing, as indicated by a previous call to
-- Set_Comes_From_Source_Default (True), then this call also resets
-- the value of Current_Error_Node.
function New_Entity
(New_Node_Kind : Node_Kind;
New_Sloc : Source_Ptr)
return Entity_Id;
-- Similar to New_Node, except that it is used only for entity nodes
-- and returns an extended node.
procedure Set_Comes_From_Source_Default (Default : Boolean);
-- Sets value of Comes_From_Source flag to be used in all subsequent
-- New_Node and New_Entity calls until another call to this procedure
-- changes the default. This value is set True during parsing and
-- False during semantic analysis. This is also used to determine
-- if New_Node and New_Entity should set Current_Error_Node.
function Get_Comes_From_Source_Default return Boolean;
pragma Inline (Get_Comes_From_Source_Default);
-- Gets the current value of the Comes_From_Source flag
procedure Preserve_Comes_From_Source (NewN, OldN : Node_Id);
pragma Inline (Preserve_Comes_From_Source);
-- When a node is rewritten, it is sometimes appropriate to preserve the
-- original comes from source indication. This is true when the rewrite
-- essentially corresponds to a transformation corresponding exactly to
-- semantics in the reference manual. This procedure copies the setting
-- of Comes_From_Source from OldN to NewN.
function Has_Extension (N : Node_Id) return Boolean;
pragma Inline (Has_Extension);
-- Returns True if the given node has an extension (i.e. was created by
-- a call to New_Entity rather than New_Node, and Nkind is in N_Entity)
procedure Change_Node (N : Node_Id; New_Node_Kind : Node_Kind);
-- This procedure replaces the given node by setting its Nkind field to
-- the indicated value and resetting all other fields to their default
-- values except for Sloc, which is unchanged, and the Parent pointer
-- and list links, which are also unchanged. All other information in
-- the original node is lost. The new node has an extension if the
-- original node had an extension.
procedure Copy_Node (Source : Node_Id; Destination : Node_Id);
-- Copy the entire contents of the source node to the destination node.
-- The contents of the source node is not affected. If the source node
-- has an extension, then the destination must have an extension also.
-- The parent pointer of the destination and its list link, if any, are
-- not affected by the copy. Note that parent pointers of descendents
-- are not adjusted, so the descendents of the destination node after
-- the Copy_Node is completed have dubious parent pointers.
function New_Copy (Source : Node_Id) return Node_Id;
-- This function allocates a completely new node, and then initializes
-- it by copying the contents of the source node into it. The contents
-- of the source node is not affected. The target node is always marked
-- as not being in a list (even if the source is a list member). The
-- new node will have an extension if the source has an extension.
-- New_Copy (Empty) returns Empty and New_Copy (Error) returns Error.
-- Note that, unlike New_Copy_Tree, New_Copy does not recursively copy any
-- descendents, so in general parent pointers are not set correctly for
-- the descendents of the copied node. Both normal and extended nodes
-- (entities) may be copied using New_Copy.
function Relocate_Node (Source : Node_Id) return Node_Id;
-- Source is a non-entity node that is to be relocated. A new node is
-- allocated and the contents of Source are copied to this node using
-- Copy_Node. The parent pointers of descendents of the node are then
-- adjusted to point to the relocated copy. The original node is not
-- modified, but the parent pointers of its descendents are no longer
-- valid. This routine is used in conjunction with the tree rewrite
-- routines (see descriptions of Replace/Rewrite).
--
-- Note that the resulting node has the same parent as the source
-- node, and is thus still attached to the tree. It is valid for
-- Source to be Empty, in which case Relocate_Node simply returns
-- Empty as the result.
function New_Copy_Tree
(Source : Node_Id;
Map : Elist_Id := No_Elist;
New_Sloc : Source_Ptr := No_Location;
New_Scope : Entity_Id := Empty)
return Node_Id;
-- Given a node that is the root of a subtree, Copy_Tree copies the entire
-- syntactic subtree, including recursively any descendents whose parent
-- field references a copied node (descendents not linked to a copied node
-- by the parent field are not copied, instead the copied tree references
-- the same descendent as the original in this case, which is appropriate
-- for non-syntactic fields such as Etype). The parent pointers in the
-- copy are properly set. Copy_Tree (Empty/Error) returns Empty/Error.
-- The one exception to the rule of not copying semantic fields is that
-- any implicit types attached to the subtree are duplicated, so that
-- the copy contains a distinct set of implicit type entities. The Map
-- argument, if set to a non-empty Elist, specifies a set of mappings
-- to be applied to entities in the tree. The map has the form:
--
-- old entity 1
-- new entity to replace references to entity 1
-- old entity 2
-- new entity to replace references to entity 2
-- ...
--
-- The call destroys the contents of Map in this case
--
-- The parameter New_Sloc, if set to a value other than No_Location, is
-- used as the Sloc value for all nodes in the new copy. If New_Sloc is
-- set to its default value No_Location, then the Sloc values of the
-- nodes in the copy are simply copied from the corresponding original.
--
-- The Comes_From_Source indication is unchanged if New_Sloc is set to
-- the default No_Location value, but is reset if New_Sloc is given, since
-- in this case the result clearly is neither a source node or an exact
-- copy of a source node.
--
-- The parameter New_Scope, if set to a value other than Empty, is the
-- value to use as the Scope for any Itypes that are copied. The most
-- typical value for this parameter, if given, is Current_Scope.
function Copy_Separate_Tree (Source : Node_Id) return Node_Id;
-- Given a node that is the root of a subtree, Copy_Separate_Tree copies
-- the entire syntactic subtree, including recursively any descendants
-- whose parent field references a copied node (descendants not linked to
-- a copied node by the parent field are also copied.) The parent pointers
-- in the copy are properly set. Copy_Separate_Tree (Empty/Error) returns
-- Empty/Error. The semantic fields are not copied and the new subtree
-- does not share any entity with source subtree.
-- But the code *does* copy semantic fields, and the description above
-- is in any case unclear on this point ??? (RBKD)
procedure Exchange_Entities (E1 : Entity_Id; E2 : Entity_Id);
-- Exchange the contents of two entities. The parent pointers are switched
-- as well as the Defining_Identifier fields in the parents, so that the
-- entities point correctly to their original parents. The effect is thus
-- to leave the tree completely unchanged in structure, except that the
-- entity ID values of the two entities are interchanged. Neither of the
-- two entities may be list members.
procedure Delete_Node (Node : Node_Id);
-- The node, which must not be a list member, is deleted from the tree and
-- its type is set to N_Unused_At_End. It is an error (not necessarily
-- detected) to reference this node after it has been deleted. The
-- implementation of the body of Atree is free to reuse the node to
-- satisfy future node allocation requests, but is not required to do so.
procedure Delete_Tree (Node : Node_Id);
-- The entire syntactic subtree referenced by Node (i.e. the given node
-- and all its syntactic descendents) are deleted as described above for
-- Delete_Node.
function Extend_Node (Node : Node_Id) return Entity_Id;
-- This function returns a copy of its input node with an extension

-- not the same as the input value, but where possible the returned
-- value will be the same as the input value (i.e. the extension will
-- occur in place). It is the caller's responsibility to ensure that

-- OK The traversal continues normally with the syntactic
-- children of the node just processed.
-- OK_Orig The traversal continues normally with the syntactic
-- children of the original node of the node just processed.
-- Skip The children of the node just processed are skipped and
-- excluded from the traversal, but otherwise processing
-- continues elsewhere in the tree.
-- Abandon The entire traversal is immediately abandoned, and the
-- original call to Traverse returns Abandon.
-- The result returned by Traverse is Abandon if processing was terminated
-- by a call to Process returning Abandon, otherwise it is OK (meaning that

-- Tree Rewrite Routines --
---------------------------
-- During the compilation process it is necessary in a number of situations
-- to rewrite the tree. In some cases, such rewrites do not affect the
-- structure of the tree, for example, when an indexed component node is
-- replaced by the corresponding call node (the parser cannot distinguish
-- between these two cases).
-- In other situations, the rewrite does affect the structure of the
-- tree. Examples are the replacement of a generic instantiation by the
-- instantiated spec and body, and the static evaluation of expressions.
-- If such structural modifications are done by the expander, there are
-- no difficulties, since the form of the tree after the expander has no
-- special significance, except as input to the backend of the compiler.
-- However, if these modifications are done by the semantic phase, then
-- it is important that they be done in a manner which allows the original
-- tree to be preserved. This is because tools like pretty printers need
-- to have this original tree structure available.
-- The subprograms in this section allow rewriting of the tree by either
-- insertion of new nodes in an existing list, or complete replacement of
-- a subtree. The resulting tree for most purposes looks as though it has
-- been really changed, and there is no trace of the original. However,
-- special subprograms, also defined in this section, allow the original
-- tree to be reconstructed if necessary.
-- For tree modifications done in the expander, it is permissible to
-- destroy the original tree, although it is also allowable to use the
-- tree rewrite routines where it is convenient to do so.
procedure Mark_Rewrite_Insertion (New_Node : Node_Id);
pragma Inline (Mark_Rewrite_Insertion);
-- This procedure marks the given node as an insertion made during a tree
-- rewriting operation. Only the root needs to be marked. The call does
-- not do the actual insertion, which must be done using one of the normal
-- list insertion routines. The node is treated normally in all respects
-- except for its response to Is_Rewrite_Insertion. The function of these
-- calls is to be able to get an accurate original tree. This helps the
-- accuracy of Sprint.Sprint_Node, and in particular, when stubs are being
-- generated, it is essential that the original tree be accurate.
function Is_Rewrite_Insertion (Node : Node_Id) return Boolean;
pragma Inline (Is_Rewrite_Insertion);
-- Tests whether the given node was marked using Set_Rewrite_Insert. This
-- is used in reconstructing the original tree (where such nodes are to
-- be eliminated from the reconstructed tree).
procedure Rewrite (Old_Node, New_Node : Node_Id);
-- This is used when a complete subtree is to be replaced. Old_Node is the
-- root of the old subtree to be replaced, and New_Node is the root of the
-- newly constructed replacement subtree. The actual mechanism is to swap
-- the contents of these two nodes fixing up the parent pointers of the
-- replaced node (we do not attempt to preserve parent pointers for the
-- original node). Neither Old_Node nor New_Node can be extended nodes.
--
-- Note: New_Node may not contain references to Old_Node, for example as
-- descendents, since the rewrite would make such references invalid. If
-- New_Node does need to reference Old_Node, then these references should
-- be to a relocated copy of Old_Node (see Relocate_Node procedure).
--
-- Note: The Original_Node function applied to Old_Node (which has now
-- been replaced by the contents of New_Node), can be used to obtain the
-- original node, i.e. the old contents of Old_Node.
procedure Replace (Old_Node, New_Node : Node_Id);
-- This is similar to Rewrite, except that the old value of Old_Node is
-- not saved, and the New_Node is deleted after the replace, since it
-- is assumed that it can no longer be legitimately needed. The flag
-- Is_Rewrite_Susbtitute will be False for the resulting node, unless
-- it was already true on entry, and Original_Node will not return the
-- original contents of the Old_Node, but rather the New_Node value (unless
-- Old_Node had already been rewritten using Rewrite). Replace also
-- preserves the setting of Comes_From_Source.
--
-- Note, New_Node may not contain references to Old_Node, for example as
-- descendents, since the rewrite would make such references invalid. If
-- New_Node does need to reference Old_Node, then these references should
-- be to a relocated copy of Old_Node (see Relocate_Node procedure).
--
-- Replace is used in certain circumstances where it is desirable to
-- suppress any history of the rewriting operation. Notably, it is used
-- when the parser has mis-classified a node (e.g. a task entry call
-- that the parser has parsed as a procedure call).
function Is_Rewrite_Substitution (Node : Node_Id) return Boolean;
pragma Inline (Is_Rewrite_Substitution);
-- Return True iff Node has been rewritten (i.e. if Node is the root
-- of a subtree which was installed using Rewrite).
function Original_Node (Node : Node_Id) return Node_Id;
pragma Inline (Original_Node);
-- If Node has not been rewritten, then returns its input argument
-- unchanged, else returns the Node for the original subtree.
--
-- Note: Parents are not preserved in original tree nodes that are
-- retrieved in this way (i.e. their children may have children whose
-- pointers which reference some other node).
-- Note: there is no direct mechanism for deleting an original node (in
-- a manner that can be reversed later). One possible approach is to use
-- Rewrite to substitute a null statement for the node to be deleted.

-- Private Part Subpackage --
-----------------------------
-- The following package contains the definition of the data structure
-- used by the implementation of the Atree package. Logically it really
-- corresponds to the private part, hence the name. The reason that it
-- is defined as a sub-package is to allow special access from clients
-- that need to see the internals of the data structures.

-------------------------
-- Tree Representation --
-------------------------
-- The nodes of the tree are stored in a table (i.e. an array). In the
-- case of extended nodes four consecutive components in the array are
-- used. There are thus two formats for array components. One is used
-- for non-extended nodes, and for the first component of extended
-- nodes. The other is used for the extension parts (second, third and
-- fourth components) of an extended node. A variant record structure
-- is used to distinguish the two formats.
type Node_Record (Is_Extension : Boolean := False) is record
-- Logically, the only field in the common part is the above
-- Is_Extension discriminant (a single bit). However, Gigi cannot
-- yet handle such a structure, so we fill out the common part of
-- the record with fields that are used in different ways for
-- normal nodes and node extensions.
Pflag1, Pflag2 : Boolean;
-- The Paren_Count field is represented using two boolean flags,
-- where Pflag1 is worth 1, and Pflag2 is worth 2. This is done
-- because we need to be easily able to reuse this field for
-- extra flags in the extended node case.
In_List : Boolean;
-- Flag used to indicate if node is a member of a list.
-- This field is considered private to the Atree package.
Unused_1 : Boolean;
-- Currently unused flag
Rewrite_Ins : Boolean;
-- Flag set by Mark_Rewrite_Insertion procedure.
-- This field is considered private to the Atree package.
Analyzed : Boolean;
-- Flag to indicate the node has been analyzed (and expanded)
Comes_From_Source : Boolean;
-- Flag to indicate that node comes from the source program (i.e.
-- was built by the parser or scanner, not the analyzer or expander).
Error_Posted : Boolean;
-- Flag to indicate that an error message has been posted on the
-- node (to avoid duplicate flags on the same node)
