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 atree.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.

   ----------------------
   -- Size of Entities --
   ----------------------

   --  Currently entities are composed of 6 sequentially allocated 32-byte
   --  nodes, considered as a single record. The following definition gives
   --  the number of extension nodes.

   Num_Extension_Nodes : Int := 5;
   --  This value is increased by one if debug flag -gnatd.N is set. This is
   --  for testing performance impact of adding a new extension node.

   ----------------------------------------
   -- 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_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 in sub-expression nodes to indicate
   --                 the level of parentheses. The settings are 0,1,2 and
   --                 3 for many. If the value is 3, then an auxiliary table
   --                 is used to indicate the real value. Set to zero for
   --                 non-subexpression nodes.

   --                 Note: the required parentheses surrounding conditional
   --                 and quantified expressions count as a level of parens
   --                 for this purpose, so e.g. in X := (if A then B else C);
   --                 Paren_Count for the right side will be 1.

   --   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

   --   ElistN        Synonym for FieldN typed as Elist_Id (Empty = No_Elist)
   --   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: in the case of ElistN and UintN fields, it is common that we
   --   end up with a value of Union_Id'(0) as the default value. This value
   --   is meaningless as a Uint or Elist_Id value. We have two choices here.
   --   We could require that all Uint and Elist fields be initialized to an
   --   appropriate value, but that's error prone, since it would be easy to
   --   miss an initialization. So instead we have the retrieval functions
   --   generate an appropriate default value (Uint_0 or No_Elist). Probably
   --   it would be cleaner to generate No_Uint in the Uint case but we got
   --   stuck with representing an "unset" size value as zero early on, and
   --   it will take a bit of fiddling to change that ???

   --   Note: the actual usage of FieldN (i.e. whether it contains a 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 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. For
   --   Flag12        historical reasons, these flag names are unused.
   --   Flag13
   --   Flag14
   --   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        299 additional flags
   --   ...
   --   Flag317

   --   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 (Empty = No_Elist)
   --   Uint6         Synonym for Field6 typed as Uint (Empty = Uint_0)

   --   Similar definitions for Field7 to Field35 (and also Node7-Node35,
   --   Elist7-Elist35, Uint7-Uint35, Ureal7-Ureal35). Note that not all
   --   these functions are defined, only the ones that are actually used.

   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

   ------------------
   -- Error Counts --
   ------------------

   --  The following variables denote the count of errors of various kinds
   --  detected in the tree. Note that these might be more logically located
   --  in Err_Vars, but we put it to deal with licensing issues (we need this
   --  to have the GPL exception licensing, since Check_Error_Detected can
   --  be called from units with this licensing).

   Serious_Errors_Detected : Nat := 0;
   --  This is a count of errors that are serious enough to stop expansion,
   --  and hence to prevent generation of an object file even if the
   --  switch -gnatQ is set. Initialized to zero at the start of compilation.
   --  Initialized for -gnatVa use, see comment above.

   Total_Errors_Detected : Nat := 0;
   --  Number of errors detected so far. Includes count of serious errors and
   --  non-serious errors, so this value is always greater than or equal to the
   --  Serious_Errors_Detected value. Initialized to zero at the start of
   --  compilation. Initialized for -gnatVa use, see comment above.

   Warnings_Detected : Nat := 0;
   --  Number of warnings detected. Initialized to zero at the start of
   --  compilation. Initialized for -gnatVa use, see comment above.

   Configurable_Run_Time_Violations : Nat := 0;
   --  Count of configurable run time violations so far. This is used to
   --  suppress certain cascaded error messages when we know that we may not
   --  have fully expanded some items, due to high integrity violations (e.g.
   --  the use of constructs not permitted by the library in use, or improper
   --  constructs in No_Run_Time mode).

   procedure Check_Error_Detected;
   --  When an anomaly is found in the tree, many semantic routines silently
   --  bail out, assuming that the anomaly was caused by a previously detected
   --  serious error (or configurable run time violation). This routine should
   --  be called in these cases, and will raise an exception if no such error
   --  has been detected. This ensure that the anomaly is never allowed to go
   --  unnoticed.

   -------------------------------
   -- 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

   --  Field6-35 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-Field35 to indicate a null node.
   --  The usage varies. The common uses are to indicate absence of an optional
   --  clause or a completely unused Field1-35 field.

   -------------------------------------
   -- Use of Synonyms for Node Fields --
   -------------------------------------

   --  A subpackage Atree.Unchecked_Access provides routines for reading and
   --  writing the fields defined above (Field1-35, Node1-35, Flag4-317 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 back end is invoked to lock the nodes table
   --  Also called after Unlock to relock???

   procedure Unlock;
   --  Unlocks nodes table, in cases where the back end needs to modify it

   procedure Tree_Read;
   --  Initializes internal tables from current tree file using the relevant
   --  Table.Tree_Read routines. 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 the relevant
   --  Table.Tree_Write routines.

   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. Note that
   --  this routine does NOT copy aspect specifications, the Has_Aspects
   --  flag in the returned node will always be False. The caller must deal
   --  with copying aspect specifications where this is required.

   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
   --  Copy_Separate_Tree, New_Copy does not recursively copy any descendents,

   -- 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.

   --  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);

   --  This is used when a complete subtree is to be replaced. Old_Node is 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_Substitution 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).

   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 that
   --  this is used extensively by ASIS on the trees constructed in ASIS mode
   --  to reconstruct the original semantic tree. See section in sinfo.ads
   --  for requirements on original nodes returned by this function.
   --
   --  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). This needs more details???
   --
   --  Note: there is no direct mechanism for deleting an original node (in

      --  for non-extended nodes, and for the first component of extended
      --  nodes. The other is used for the extension parts (second, third,
      --  fourth and fifth components) of an extended node. A variant record
