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
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.

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

133   --   Field2

135   --   Field4
136   --   Field5        Five fields holding Union_Id values
137
138   --   ElistN        Synonym for FieldN typed as Elist_Id (Empty = No_Elist)
139   --   ListN         Synonym for FieldN typed as List_Id
140   --   NameN         Synonym for FieldN typed as Name_Id
141   --   NodeN         Synonym for FieldN typed as Node_Id
142   --   StrN          Synonym for FieldN typed as String_Id
143   --   UintN         Synonym for FieldN typed as Uint (Empty = Uint_0)
144   --   UrealN        Synonym for FieldN typed as Ureal
145
146   --   Note: in the case of ElistN and UintN fields, it is common that we
147   --   end up with a value of Union_Id'(0) as the default value. This value
148   --   is meaningless as a Uint or Elist_Id value. We have two choices here.
149   --   We could require that all Uint and Elist fields be initialized to an
150   --   appropriate value, but that's error prone, since it would be easy to
151   --   miss an initialization. So instead we have the retrieval functions
152   --   generate an appropriate default value (Uint_0 or No_Elist). Probably
153   --   it would be cleaner to generate No_Uint in the Uint case but we got
154   --   stuck with representing an "unset" size value as zero early on, and
155   --   it will take a bit of fiddling to change that ???
156
157   --   Note: the actual usage of FieldN (i.e. whether it contains a Elist_Id,
158   --   List_Id, Name_Id, Node_Id, String_Id, Uint or Ureal) depends on the
159   --   value in Nkind. Generally the access to this field is always via the
160   --   functional interface, so the field names ElistN, ListN, NameN, NodeN,
161   --   StrN, UintN and UrealN are used only in the bodies of the access
162   --   functions (i.e. in the bodies of Sinfo and Einfo). These access
163   --   functions contain debugging code that checks that the use is
164   --   consistent with Nkind and Ekind values.
165
166   --   However, in specialized circumstances (examples are the circuit in
167   --   generic instantiation to copy trees, and in the tree dump routine),
168   --   it is useful to be able to do untyped traversals, and an internal
169   --   package in Atree allows for direct untyped accesses in such cases.
170
171   --   Flag4         Fifteen Boolean flags (use depends on Nkind and
172   --   Flag5         Ekind, as described for FieldN). Again the access
173   --   Flag6         is usually via subprograms in Sinfo and Einfo which
174   --   Flag7         provide high-level synonyms for these flags, and
175   --   Flag8         contain debugging code that checks that the values
176   --   Flag9         in Nkind and Ekind are appropriate for the access.
177   --   Flag10
178   --   Flag11        Note that Flag1-3 are missing from this list. For
179   --   Flag12        historical reasons, these flag names are unused.

232   -----------------------

237
238   --  Note: Empty is not used to describe an empty list. Instead in this
239   --  case the node field contains a list which is empty, and these cases
240   --  should be distinguished (essentially from a type point of view, Empty
241   --  is a Node, and is thus not a list).
242
243   --  Note: Empty does in fact correspond to an allocated node. Only the
244   --  Nkind field of this node may be referenced. It contains N_Empty, which
245   --  uniquely identifies the empty case. This allows the Nkind field to be
246   --  dereferenced before the check for Empty which is sometimes useful.
247
248   -----------------------
249   -- Use of Error Node --
250   -----------------------
251
252   --  The Error node is used during syntactic and semantic analysis to
253   --  indicate that the corresponding piece of syntactic structure or
254   --  semantic meaning cannot properly be represented in the tree because
255   --  of an illegality in the program.

257   --  If an Error node is encountered, then you know that a previous

265
266   --  The current error node is a global location indicating the current
267   --  node that is being processed for the purposes of placing a compiler

848   -- Tree Rewrite Routines --
849   ---------------------------
850
851   --  During the compilation process it is necessary in a number of situations
852   --  to rewrite the tree. In some cases, such rewrites do not affect the
853   --  structure of the tree, for example, when an indexed component node is
854   --  replaced by the corresponding call node (the parser cannot distinguish
855   --  between these two cases).
856
857   --  In other situations, the rewrite does affect the structure of the
858   --  tree. Examples are the replacement of a generic instantiation by the
859   --  instantiated spec and body, and the static evaluation of expressions.
860
861   --  If such structural modifications are done by the expander, there are
862   --  no difficulties, since the form of the tree after the expander has no
863   --  special significance, except as input to the backend of the compiler.
864   --  However, if these modifications are done by the semantic phase, then
865   --  it is important that they be done in a manner which allows the original
866   --  tree to be preserved. This is because tools like pretty printers need
867   --  to have this original tree structure available.
868
869   --  The subprograms in this section allow rewriting of the tree by either

872   --  been really changed, and there is no trace of the original. However,
873   --  special subprograms, also defined in this section, allow the original
874   --  tree to be reconstructed if necessary.
875
876   --  For tree modifications done in the expander, it is permissible to
