  44 package Atree is
  45
  46 --  This package defines the format of the tree used to represent the Ada
  47 --  program internally. Syntactic and semantic information is combined in
  48 --  this tree. There is no separate symbol table structure.
  49
  50 --  WARNING: There is a C version of this package. Any changes to this
  51 --  source file must be properly reflected in the C header file atree.h
  52
  53 --  Package Atree defines the basic structure of the tree and its nodes and
  54 --  provides the basic abstract interface for manipulating the tree. Two
  55 --  other packages use this interface to define the representation of Ada
  56 --  programs using this tree format. The package Sinfo defines the basic
  57 --  representation of the syntactic structure of the program, as output
  58 --  by the parser. The package Entity_Info defines the semantic information
  59 --  which is added to the tree nodes that represent declared entities (i.e.
  60 --  the information which might typically be described in a separate symbol
  61 --  table structure).
  62
  63 --  The front end of the compiler first parses the program and generates a
  64 --  tree that is simply a syntactic representation of the program in abstract
  65 --  syntax tree format. Subsequent processing in the front end traverses the
  66 --  tree, transforming it in various ways and adding semantic information.

  76    Num_Extension_Nodes : Node_Id := 5;
  77    --  This value is increased by one if debug flag -gnatd.N is set. This is

  82    -- Definitions of Fields in Tree Node --
  83    ----------------------------------------
  84
  85    --  The representation of the tree is completely hidden, using a functional
  86    --  interface for accessing and modifying the contents of nodes. Logically
  87    --  a node contains a number of fields, much as though the nodes were
  88    --  defined as a record type. The fields in a node are as follows:
  89
  90    --   Nkind         Indicates the kind of the node. This field is present
  91    --                 in all nodes. The type is Node_Kind, which is declared
  92    --                 in the package Sinfo.
  93
  94    --   Sloc          Location (Source_Ptr) of the corresponding token
  95    --                 in the Source buffer. The individual node definitions
  96    --                 show which token is referenced by this pointer.
  97
  98    --   In_List       A flag used to indicate if the node is a member
  99    --                 of a node list.
 100
 101    --   Rewrite_Ins   A flag set if a node is marked as a rewrite inserted
 102    --                 node as a result of a call to Mark_Rewrite_Insertion.
 103
 104    --   Paren_Count   A 2-bit count used in sub-expression nodes to indicate
 105    --                 the level of parentheses. The settings are 0,1,2 and
 106    --                 3 for many. If the value is 3, then an auxiliary table
 107    --                 is used to indicate the real value. Set to zero for
 108    --                 non-subexpression nodes.
 109
 110    --                 Note: the required parentheses surrounding conditional
 111    --                 and quantified expressions count as a level of parens
 112    --                 for this purpose, so e.g. in X := (if A then B else C);
 113    --                 Paren_Count for the right side will be 1.
 114
 115    --   Comes_From_Source
 116    --                 This flag is present in all nodes. It is set if the
 117    --                 node is built by the scanner or parser, and clear if
 118    --                 the node is built by the analyzer or expander. It
 119    --                 indicates that the node corresponds to a construct
 120    --                 that appears in the original source program.
 121
 122    --   Analyzed      This flag is present in all nodes. It is set when
 123    --                 a node is analyzed, and is used to avoid analyzing
 124    --                 the same node twice. Analysis includes expansion if
 125    --                 expansion is active, so in this case if the flag is
 126    --                 set it means the node has been analyzed and expanded.
 127
 128    --   Error_Posted  This flag is present in all nodes. It is set when
 129    --                 an error message is posted which is associated with
 130    --                 the flagged node. This is used to avoid posting more
 131    --                 than one message on the same node.

 134    --   Field2
 135    --   Field3
 136    --   Field4
 137    --   Field5        Five fields holding Union_Id values
 138
 139    --   ElistN        Synonym for FieldN typed as Elist_Id (Empty = No_Elist)
 140    --   ListN         Synonym for FieldN typed as List_Id
 141    --   NameN         Synonym for FieldN typed as Name_Id
 142    --   NodeN         Synonym for FieldN typed as Node_Id
 143    --   StrN          Synonym for FieldN typed as String_Id
 144    --   UintN         Synonym for FieldN typed as Uint (Empty = Uint_0)
 145    --   UrealN        Synonym for FieldN typed as Ureal
 146
 147    --   Note: in the case of ElistN and UintN fields, it is common that we
 148    --   end up with a value of Union_Id'(0) as the default value. This value
 149    --   is meaningless as a Uint or Elist_Id value. We have two choices here.
 150    --   We could require that all Uint and Elist fields be initialized to an
 151    --   appropriate value, but that's error prone, since it would be easy to
 152    --   miss an initialization. So instead we have the retrieval functions
 153    --   generate an appropriate default value (Uint_0 or No_Elist). Probably
 154    --   it would be cleaner to generate No_Uint in the Uint case but we got
 155    --   stuck with representing an "unset" size value as zero early on, and
 156    --   it will take a bit of fiddling to change that ???
 157
 158    --   Note: the actual usage of FieldN (i.e. whether it contains a Elist_Id,
 159    --   List_Id, Name_Id, Node_Id, String_Id, Uint or Ureal) depends on the
 160    --   value in Nkind. Generally the access to this field is always via the
 161    --   functional interface, so the field names ElistN, ListN, NameN, NodeN,
 162    --   StrN, UintN and UrealN are used only in the bodies of the access
 163    --   functions (i.e. in the bodies of Sinfo and Einfo). These access
 164    --   functions contain debugging code that checks that the use is
 165    --   consistent with Nkind and Ekind values.
 166
 167    --   However, in specialized circumstances (examples are the circuit in
 168    --   generic instantiation to copy trees, and in the tree dump routine),
 169    --   it is useful to be able to do untyped traversals, and an internal
 170    --   package in Atree allows for direct untyped accesses in such cases.

 172    --   Flag0         Nineteen Boolean flags (use depends on Nkind and
 173    --   Flag1         Ekind, as described for FieldN). Again the access
 174    --   Flag2         is usually via subprograms in Sinfo and Einfo which
 175    --   Flag3         provide high-level synonyms for these flags, and
 176    --   Flag4         contain debugging code that checks that the values
 177    --   Flag5         in Nkind and Ekind are appropriate for the access.

 184    --   Flag12        table, but that's a detail of the implementation which
 185    --   Flag13        is entirely hidden by the funcitonal interface.

 257    -- Use of Error Node --

 357    -- Use of Synonyms for Node Fields --
 358    -------------------------------------
 359
 360    --  A subpackage Atree.Unchecked_Access provides routines for reading and
 361    --  writing the fields defined above (Field1-35, Node1-35, Flag0-317 etc).
 362    --  These unchecked access routines can be used for untyped traversals.
 363    --  In addition they are used in the implementations of the Sinfo and
 364    --  Einfo packages. These packages both provide logical synonyms for
 365    --  the generic fields, together with an appropriate set of access routines.
 366    --  Normally access to information within tree nodes uses these synonyms,
 367    --  providing a high level typed interface to the tree information.

 905    --  replaced by the corresponding call node (the parser cannot distinguish
 906    --  between these two cases).
