44package 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 source
51--  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 other
55--  packages use this interface to define the representation of Ada programs
56--  using this tree format. The package Sinfo defines the basic representation
57--  of the syntactic structure of the program, as output by the parser. The
58--  package Einfo defines the semantic information which is added to the tree
59--  nodes that represent declared entities (i.e. the information which might
60--  typically be described in a separate symbol table structure).
61
62--  The front end of the compiler first parses the program and generates a
63--  tree that is simply a syntactic representation of the program in abstract
64--  syntax tree format. Subsequent processing in the front end traverses the
65--  tree, transforming it in various ways and adding semantic information.

70
71   --  Currently entities are composed of 7 sequentially allocated 32-byte

75   Num_Extension_Nodes : Node_Id := 6;
76   --  This value is increased by one if debug flag -gnatd.N is set. This is
77   --  for testing performance impact of adding a new extension node. We make
78   --  this of type Node_Id for easy reference in loops using this value.
79   --  Print_Statistics can be used to display statistics on entities & nodes.
80   --  Measurements conducted for the 5->6 bump showed an increase from 1.81 to
81   --  2.01 for the nodes/entities ratio and a 2% increase in compilation time
82   --  on average for the GCC-based compiler at -O0 on a 32-bit x86 host.

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

136   --   Field1
137   --   Field2
138   --   Field3
139   --   Field4
140   --   Field5        Five fields holding Union_Id values
141
142   --   ElistN        Synonym for FieldN typed as Elist_Id (Empty = No_Elist)
143   --   ListN         Synonym for FieldN typed as List_Id
144   --   NameN         Synonym for FieldN typed as Name_Id
145   --   NodeN         Synonym for FieldN typed as Node_Id
146   --   StrN          Synonym for FieldN typed as String_Id
147   --   UintN         Synonym for FieldN typed as Uint (Empty = Uint_0)
148   --   UrealN        Synonym for FieldN typed as Ureal
149
150   --   Note: in the case of ElistN and UintN fields, it is common that we
151   --   end up with a value of Union_Id'(0) as the default value. This value
152   --   is meaningless as a Uint or Elist_Id value. We have two choices here.
153   --   We could require that all Uint and Elist fields be initialized to an
154   --   appropriate value, but that's error prone, since it would be easy to
155   --   miss an initialization. So instead we have the retrieval functions
156   --   generate an appropriate default value (Uint_0 or No_Elist). Probably
157   --   it would be cleaner to generate No_Uint in the Uint case but we got
158   --   stuck with representing an "unset" size value as zero early on, and
159   --   it will take a bit of fiddling to change that ???
160
161   --   Note: the actual usage of FieldN (i.e. whether it contains a Elist_Id,
162   --   List_Id, Name_Id, Node_Id, String_Id, Uint or Ureal) depends on the
163   --   value in Nkind. Generally the access to this field is always via the
164   --   functional interface, so the field names ElistN, ListN, NameN, NodeN,
165   --   StrN, UintN and UrealN are used only in the bodies of the access
166   --   functions (i.e. in the bodies of Sinfo and Einfo). These access
167   --   functions contain debugging code that checks that the use is
168   --   consistent with Nkind and Ekind values.
169
170   --   However, in specialized circumstances (examples are the circuit in
171   --   generic instantiation to copy trees, and in the tree dump routine),
172   --   it is useful to be able to do untyped traversals, and an internal
173   --   package in Atree allows for direct untyped accesses in such cases.
174
175   --   Flag0         Nineteen Boolean flags (use depends on Nkind and
176   --   Flag1         Ekind, as described for FieldN). Again the access
177   --   Flag2         is usually via subprograms in Sinfo and Einfo which
178   --   Flag3         provide high-level synonyms for these flags, and
179   --   Flag4         contain debugging code that checks that the values
180   --   Flag5         in Nkind and Ekind are appropriate for the access.

187   --   Flag12        table, but that's a detail of the implementation which
188   --   Flag13        is entirely hidden by the functional interface.

246   --  syntax has an optional component, then the corresponding field will be
247   --  set to Empty if the component is missing.
248
249   --  Note: Empty is not used to describe an empty list. Instead in this
250   --  case the node field contains a list which is empty, and these cases
251   --  should be distinguished (essentially from a type point of view, Empty
252   --  is a Node, and is thus not a list).
253
254   --  Note: Empty does in fact correspond to an allocated node. Only the
255   --  Nkind field of this node may be referenced. It contains N_Empty, which
256   --  uniquely identifies the empty case. This allows the Nkind field to be
257   --  dereferenced before the check for Empty which is sometimes useful.
258
259   -----------------------
260   -- Use of Error Node --
261   -----------------------
262
263   --  The Error node is used during syntactic and semantic analysis to
264   --  indicate that the corresponding piece of syntactic structure or

382   -------------------------------------
383
384   --  A subpackage Atree.Unchecked_Access provides routines for reading and
385   --  writing the fields defined above (Field1-35, Node1-35, Flag0-317 etc).
386   --  These unchecked access routines can be used for untyped traversals.
387   --  In addition they are used in the implementations of the Sinfo and
388   --  Einfo packages. These packages both provide logical synonyms for
389   --  the generic fields, together with an appropriate set of access routines.
390   --  Normally access to information within tree nodes uses these synonyms,
