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. ---------------------------------------- -- 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. -- 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 235 additional flags -- ... -- Flag254 -- 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 Field28 (and Node7-Node28, -- Elist7-Elist28, Uint7-Uint28, Ureal7-Ureal28). 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 ------------------------------- -- 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 -- Field6-29 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 (Field1-27, Node1-27, Flag4-254 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, -- 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 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 new subtree does not share entities with the source, -- but has new entities with the same name. Most of the time this routine -- is called on an unanalyzed tree, and no semantic information is copied. -- However, to ensure that no entities are shared between the two when the -- source is already analyzed, entity fields in the copy are zeroed out. function Copy_Separate_List (Source : List_Id) return List_Id; -- Applies Copy_Separate_Tree to each element of the Source list, returning -- a new list of the results of these copy operations. 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. function Extend_Node (Node : Node_Id) return Entity_Id; -- This function returns a copy of its input node with an extension added. -- The fields of the extension are set to Empty. Due to the way extensions -- are handled (as four consecutive array elements), it may be necessary -- to reallocate the node, so that the returned value is 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 any pointers to the original node -- are appropriately updated. This function is used only by Sinfo.CN to -- change nodes into their corresponding entities. type Report_Proc is access procedure (Target : Node_Id; Source : Node_Id); procedure Set_Reporting_Proc (P : Report_Proc); -- Register a procedure that is invoked when a node is allocated, replaced -- or rewritten. type Traverse_Result is (Abandon, OK, OK_Orig, Skip); -- This is the type of the result returned by the Process function passed -- to Traverse_Func and Traverse_Proc. See below for details. subtype Traverse_Final_Result is Traverse_Result range Abandon .. OK; -- This is the type of the final result returned Traverse_Func, based on -- the results of Process calls. See below for details. generic with function Process (N : Node_Id) return Traverse_Result is <>; function Traverse_Func (Node : Node_Id) return Traverse_Final_Result; -- This is a generic function that, given the parent node for a subtree, -- traverses all syntactic nodes of this tree, calling the given function -- Process on each one, in pre order (i.e. top-down). The order of -- traversing subtrees is arbitrary. The traversal is controlled as follows -- by the result returned by Process: -- 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 -- all calls to process returned either OK, OK_Orig, or Skip). generic with function Process (N : Node_Id) return Traverse_Result is <>; procedure Traverse_Proc (Node : Node_Id); pragma Inline (Traverse_Proc); -- This is the same as Traverse_Func except that no result is returned, -- i.e. Traverse_Func is called and the result is simply discarded. --------------------------- -- Node Access Functions -- --------------------------- -- The following functions return the contents of the indicated field of -- the node referenced by the argument, which is a Node_Id. function Nkind (N : Node_Id) return Node_Kind; pragma Inline (Nkind); function Analyzed (N : Node_Id) return Boolean; pragma Inline (Analyzed); function Has_Aspects (N : Node_Id) return Boolean; pragma Inline (Has_Aspects); function Comes_From_Source (N : Node_Id) return Boolean; pragma Inline (Comes_From_Source); function Error_Posted (N : Node_Id) return Boolean; pragma Inline (Error_Posted); function Sloc (N : Node_Id) return Source_Ptr; pragma Inline (Sloc); function Paren_Count (N : Node_Id) return Nat; pragma Inline (Paren_Count); function Parent (N : Node_Id) return Node_Id; pragma Inline (Parent); -- Returns the parent of a node if the node is not a list member, or else -- the parent of the list containing the node if the node is a list member. function No (N : Node_Id) return Boolean; pragma Inline (No); -- Tests given Id for equality with the Empty node. This allows notations -- like "if No (Variant_Part)" as opposed to "if Variant_Part = Empty". function Present (N : Node_Id) return Boolean; pragma Inline (Present); -- Tests given Id for inequality with the Empty node. This allows notations -- like "if Present (Statement)" as opposed to "if Statement /= Empty". --------------------- -- Node_Kind Tests -- --------------------- -- These are like the functions in Sinfo, but the first argument is a -- Node_Id, and the tested field is Nkind (N). function Nkind_In (N : Node_Id; V1 : Node_Kind; V2 : Node_Kind) return Boolean; function Nkind_In (N : Node_Id; V1 : Node_Kind; V2 : Node_Kind; V3 : Node_Kind) return Boolean; function Nkind_In (N : Node_Id; V1 : Node_Kind; V2 : Node_Kind; V3 : Node_Kind; V4 : Node_Kind) return Boolean; function Nkind_In (N : Node_Id; V1 : Node_Kind; V2 : Node_Kind; V3 : Node_Kind; V4 : Node_Kind; V5 : Node_Kind) return Boolean; function Nkind_In (N : Node_Id; V1 : Node_Kind; V2 : Node_Kind; V3 : Node_Kind; V4 : Node_Kind; V5 : Node_Kind; V6 : Node_Kind) return Boolean; function Nkind_In (N : Node_Id; V1 : Node_Kind; V2 : Node_Kind; V3 : Node_Kind; V4 : Node_Kind; V5 : Node_Kind; V6 : Node_Kind; V7 : Node_Kind) return Boolean; function Nkind_In (N : Node_Id; V1 : Node_Kind; V2 : Node_Kind; V3 : Node_Kind; V4 : Node_Kind; V5 : Node_Kind; V6 : Node_Kind; V7 : Node_Kind; V8 : Node_Kind) return Boolean; function Nkind_In (N : Node_Id; V1 : Node_Kind; V2 : Node_Kind; V3 : Node_Kind; V4 : Node_Kind; V5 : Node_Kind; V6 : Node_Kind; V7 : Node_Kind; V8 : Node_Kind; V9 : Node_Kind) return Boolean; pragma Inline (Nkind_In); -- Inline all above functions ----------------------- -- Entity_Kind_Tests -- ----------------------- -- Utility functions to test whether an Entity_Kind value, either given -- directly as the first argument, or the Ekind field of an Entity give -- as the first argument, matches any of the given list of Entity_Kind -- values.

The second parameter is the new value -- to be set in the specified field. Note that Set_Nkind is in the next -- section, since its use is restricted. procedure Set_Sloc (N : Node_Id; Val : Source_Ptr); pragma Inline (Set_Sloc); procedure Set_Paren_Count (N : Node_Id; Val : Nat); pragma Inline (Set_Paren_Count); procedure Set_Parent (N : Node_Id; Val : Node_Id); pragma Inline (Set_Parent); procedure Set_Analyzed (N : Node_Id; Val : Boolean := True); pragma Inline (Set_Analyzed); procedure Set_Error_Posted (N : Node_Id; Val : Boolean := True); pragma Inline (Set_Error_Posted); procedure Set_Comes_From_Source (N : Node_Id; Val : Boolean); pragma Inline (Set_Comes_From_Source); -- Note that this routine is very rarely used, since usually the -- default mechanism provided sets the right value, but in some -- unusual cases, the value needs to be reset (e.g. when a source -- node is copied, and the copy must not have Comes_From_Source set. procedure Set_Has_Aspects (N : Node_Id; Val : Boolean := True); pragma Inline (Set_Has_Aspects); procedure Set_Original_Node (N : Node_Id; Val : Node_Id); pragma Inline (Set_Original_Node); -- Note that this routine is used only in very peculiar cases. In normal -- cases, the Original_Node link is set by calls to Rewrite. We currently -- use it in ASIS mode to manually set the link from pragma expressions -- to their aspect original source expressions, so that the original source -- expressions accessed by ASIS are also semantically analyzed. ------------------------------ -- Entity Update Procedures -- ------------------------------ -- The following procedures apply only to Entity_Id values, i.e. -- to extended nodes. procedure Basic_Set_Convention (E : Entity_Id; Val : Convention_Id); pragma Inline (Basic_Set_Convention); -- Clients should use Sem_Util.Set_Convention rather than calling this -- routine directly, as Set_Convention also deals with the special -- processing required for access types. procedure Set_Ekind (E : Entity_Id; Val : Entity_Kind); pragma Inline (Set_Ekind); --------------------------- -- 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 Mark_Rewrite_Insertion. -- This is used in reconstructing the original tree (where such nodes are -- to be eliminated). 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_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). 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. ----------------------------------- -- Generic Field Access Routines -- ----------------------------------- -- This subpackage provides the functions for accessing and procedures for -- setting fields that are normally referenced by wrapper subprograms (e.g. -- logical synonyms defined in packages Sinfo and Einfo, or specialized -- routines such as Rewrite (for Original_Node), or the node creation -- routines (for Set_Nkind).
