| |
| -- This package defines the structure of the abstract syntax tree. The Tree |
| -- package provides a basic tree structure. Sinfo describes how this structure |
| -- is used to represent the syntax of an Ada program. |
| |
| -- The grammar in the RM is followed very closely in the tree design, and is |
| -- repeated as part of this source file. |
| |
| -- The tree contains not only the full syntactic representation of the |
| -- program, but also the results of semantic analysis. In particular, the |
| -- nodes for defining identifiers, defining character literals and defining |
| -- operator symbols, collectively referred to as entities, represent what |
| -- would normally be regarded as the symbol table information. In addition a |
| -- number of the tree nodes contain semantic information. |
| |

| --------------------------------- |
| -- Making Changes to This File -- |
| --------------------------------- |
| |
| -- If changes are made to this file, a number of related steps must be |
| -- carried out to ensure consistency. First, if a field access function is |
| -- added, it appears in these places: |
| |
| -- In sinfo.ads: |
| -- The documentation associated with the field (if semantic) |
| -- The documentation associated with the node |
| -- The spec of the access function |
| -- The spec of the set procedure |
| -- The entries in Is_Syntactic_Field |
| -- The pragma Inline for the access function |
| -- The pragma Inline for the set procedure |
| -- In sinfo.adb: |
| -- The body of the access function |
| -- The body of the set procedure |
| |
| -- The field chosen must be consistent in all places, and, for a node that |
| -- is a subexpression, must not overlap any of the standard expression |
| -- fields. |
| |
| -- In addition, if any of the standard expression fields is changed, then |
| -- the utility program which creates the Treeprs spec (in file treeprs.ads) |
| -- must be updated appropriately, since it special cases expression fields. |
| |
| -- If a new tree node is added, then the following changes are made |
| |
| -- Add it to the documentation in the appropriate place |
| -- Add its fields to this documentation section |
| -- Define it in the appropriate classification in Node_Kind |
| -- In the body (sinfo), add entries to the access functions for all |
| -- its fields (except standard expression fields) to include the new |
| -- node in the checks. |
| -- Add an appropriate section to the case statement in sprint.adb |
| -- Add an appropriate section to the case statement in sem.adb |
| -- Add an appropriate section to the case statement in exp_util.adb |
| -- (Insert_Actions procedure) |
| -- For a subexpression, add an appropriate section to the case |
| -- statement in sem_eval.adb |
| -- For a subexpression, add an appropriate section to the case |
| -- statement in sem_res.adb |
| |
| -- Finally, four utility programs must be run: |
| |
| -- (Optional.) Run CSinfo to check that you have made the changes |
| -- consistently. It checks most of the rules given above. This utility |
| -- reads sinfo.ads and sinfo.adb and generates a report to standard |
| -- output. This step is optional because XSinfo runs CSinfo. |
| |
| -- Run XSinfo to create sinfo.h, the corresponding C header. This |
| -- utility reads sinfo.ads and generates sinfo.h. Note that it does |
| -- not need to read sinfo.adb, since the contents of the body are |
| -- algorithmically determinable from the spec. |
| |
| -- Run XTreeprs to create treeprs.ads, an updated version of the module |
| -- that is used to drive the tree print routine. This utility reads (but |
| -- does not modify) treeprs.adt, the template that provides the basic |
| -- structure of the file, and then fills in the data from the comments |
| -- in sinfo.ads. |
| |
| -- Run XNmake to create nmake.ads and nmake.adb, the package body and |
| -- spec of the Nmake package which contains functions for constructing |
| -- nodes. |
| |
| -- The above steps are done automatically by the build scripts when you do |
| -- a full bootstrap. |
| |
| -- Note: sometime we could write a utility that actually generated the body |
| -- of sinfo from the spec instead of simply checking it, since, as noted |
| -- above, the contents of the body can be determined from the spec. |
| |
| -------------------------------- |
| -- Implicit Nodes in the Tree -- |
| -------------------------------- |
| |
| -- Generally the structure of the tree very closely follows the grammar as |
| -- defined in the RM. However, certain nodes are omitted to save space and |
| -- simplify semantic processing. Two general classes of such omitted nodes |
| -- are as follows: |
| |
| -- If the only possibilities for a non-terminal are one or more other |
| -- non-terminals (i.e. the rule is a "skinny" rule), then usually the |
| -- corresponding node is omitted from the tree, and the target construct |
| -- appears directly. For example, a real type definition is either |
| -- floating point definition or a fixed point definition. No explicit node |
| -- appears for real type definition. Instead either the floating point |
| -- definition or fixed point definition appears directly. |
| |
| -- If a non-terminal corresponds to a list of some other non-terminal |
| -- (possibly with separating punctuation), then usually it is omitted from |
| -- the tree, and a list of components appears instead. For example, |
| -- sequence of statements does not appear explicitly in the tree. Instead |
| -- a list of statements appears directly. |
| |
| -- Some additional cases of omitted nodes occur and are documented |
| -- individually. In particular, many nodes are omitted in the tree |
| -- generated for an expression. |
| |
| ------------------------------------------- |
| -- Handling of Defining Identifier Lists -- |
| ------------------------------------------- |
| |
| -- In several declarative forms in the syntax, lists of defining |
| -- identifiers appear (object declarations, component declarations, number |
| -- declarations etc.) |
| |
| -- The semantics of such statements are equivalent to a series of identical |
| -- declarations of single defining identifiers (except that conformance |
| -- checks require the same grouping of identifiers in the parameter case). |
| |
| -- To simplify semantic processing, the parser breaks down such multiple |
| -- declaration cases into sequences of single declarations, duplicating |
| -- type and initialization information as required. The flags More_Ids and |
| -- Prev_Ids are used to record the original form of the source in the case |
| -- where the original source used a list of names, More_Ids being set on |
| -- all but the last name and Prev_Ids being set on all but the first name. |
| -- These flags are used to reconstruct the original source (e.g. in the |
| -- Sprint package), and also are included in the conformance checks, but |
| -- otherwise have no semantic significance. |
| |
| -- Note: the reason that we use More_Ids and Prev_Ids rather than |
| -- First_Name and Last_Name flags is so that the flags are off in the |
| -- normal one identifier case, which minimizes tree print output. |
| |
| ----------------------- |
| -- Use of Node Lists -- |
| ----------------------- |
| |
| -- With a few exceptions, if a construction of the form {non-terminal} |
| -- appears in the tree, lists are used in the corresponding tree node (see |
| -- package Nlists for handling of node lists). In this case a field of the |
| -- parent node points to a list of nodes for the non-terminal. The field |
| -- name for such fields has a plural name which always ends in "s". For |
| -- example, a case statement has a field Alternatives pointing to list of |
| -- case statement alternative nodes. |
| |
| -- Only fields pointing to lists have names ending in "s", so generally the |
| -- structure is strongly typed, fields not ending in s point to single |
| -- nodes, and fields ending in s point to lists. |
| |
| -- The following example shows how a traversal of a list is written. We |
| -- suppose here that Stmt points to a N_Case_Statement node which has a |
| -- list field called Alternatives: |
| |
| -- Alt := First (Alternatives (Stmt)); |
| -- while Present (Alt) loop |
| -- .. |
| -- -- processing for case statement alternative Alt |
| -- .. |
| -- Alt := Next (Alt); |
| -- end loop; |
| |
| -- The Present function tests for Empty, which in this case signals the end |
| -- of the list. First returns Empty immediately if the list is empty. |
| -- Present is defined in Atree, First and Next are defined in Nlists. |
| |
| -- The exceptions to this rule occur with {DEFINING_IDENTIFIERS} in all |
| -- contexts, which is handled as described in the previous section, and |
| -- with {,library_unit_NAME} in the N_With_Clause mode, which is handled |
| -- using the First_Name and Last_Name flags, as further detailed in the |
| -- description of the N_With_Clause node. |
| |
| ------------- |
| -- Pragmas -- |
| ------------- |
| |
| -- Pragmas can appear in many different context, but are not included in |
| -- the grammar. Still they must appear in the tree, so they can be properly |
| -- processed. |
| |
| -- Two approaches are used. In some cases, an extra field is defined in an |
| -- appropriate node that contains a list of pragmas appearing in the |
| -- expected context. For example pragmas can appear before an |
| -- Accept_Alternative in a Selective_Accept_Statement, and these pragmas |
| -- appear in the Pragmas_Before field of the N_Accept_Alternative node. |
| |
| -- The other approach is to simply allow pragmas to appear in syntactic |
| -- lists where the grammar (of course) does not include the possibility. |
| -- For example, the Variants field of an N_Variant_Part node points to a |
| -- list that can contain both N_Pragma and N_Variant nodes. |
| |
| -- To make processing easier in the latter case, the Nlists package |
| -- provides a set of routines (First_Non_Pragma, Last_Non_Pragma, |
| -- Next_Non_Pragma, Prev_Non_Pragma) that allow such lists to be handled |
| -- ignoring all pragmas. |
| |
| -- In the case of the variants list, we can either write: |
| |
| -- Variant := First (Variants (N)); |
| -- while Present (Variant) loop |
| -- ... |
| -- Variant := Next (Variant); |
| -- end loop; |
| |
| -- or |
| |
| -- Variant := First_Non_Pragma (Variants (N)); |
| -- while Present (Variant) loop |
| -- ... |
| -- Variant := Next_Non_Pragma (Variant); |
| -- end loop; |
| |
| -- In the first form of the loop, Variant can either be an N_Pragma or an |
| -- N_Variant node. In the second form, Variant can only be N_Variant since |
| -- all pragmas are skipped. |
| |
| --------------------- |
| -- Optional Fields -- |
| --------------------- |
| |
| -- Fields which correspond to a section of the syntax enclosed in square |
| -- brackets are generally omitted (and the corresponding field set to Empty |
| -- for a node, or No_List for a list). The documentation of such fields |
| -- notes these cases. One exception to this rule occurs in the case of |
| -- possibly empty statement sequences (such as the sequence of statements |
| -- in an entry call alternative). Such cases appear in the syntax rules as |
| -- [SEQUENCE_OF_STATEMENTS] and the fields corresponding to such optional |
| -- statement sequences always contain an empty list (not No_List) if no |
| -- statements are present. |
| |
| -- Note: the utility program that constructs the body and spec of the Nmake |
| -- package relies on the format of the comments to determine if a field |
| -- should have a default value in the corresponding make routine. The rule |
| -- is that if the first line of the description of the field contains the |
| -- string "(set to xxx if", then a default value of xxx is provided for |
| -- this field in the corresponding Make_yyy routine. |
| |
| ----------------------------------- |
| -- Note on Body/Spec Terminology -- |
| ----------------------------------- |
| |
| -- In informal discussions about Ada, it is customary to refer to package |
| -- and subprogram specs and bodies. However, this is not technically |
| -- correct, what is normally referred to as a spec or specification is in |
| -- fact a package declaration or subprogram declaration. We are careful in |
| -- GNAT to use the correct terminology and in particular, the full word |
| -- specification is never used as an incorrect substitute for declaration. |
| -- The structure and terminology used in the tree also reflects the grammar |
| -- and thus uses declaration and specification in the technically correct |
| -- manner. |
| |
| -- However, there are contexts in which the informal terminology is useful. |
| -- We have the word "body" to refer to the Interp_Etype declared by the |
| -- declaration of a unit body, and in some contexts we need similar term to |
| -- refer to the entity declared by the package or subprogram declaration, |
| -- and simply using declaration can be confusing since the body also has a |
| -- declaration. |
| |
| -- An example of such a context is the link between the package body and |
| -- its declaration. With_Declaration is confusing, since the package body |
| -- itself is a declaration. |
| |
| -- To deal with this problem, we reserve the informal term Spec, i.e. the |
| -- popular abbreviation used in this context, to refer to the entity |
| -- declared by the package or subprogram declaration. So in the above |
| -- example case, the field in the body is called With_Spec. |
| |
| -- Another important context for the use of the word Spec is in error |
| -- messages, where a hyper-correct use of declaration would be confusing to |
| -- a typical Ada programmer, and even for an expert programmer can cause |
| -- confusion since the body has a declaration as well. |
| |
| -- So, to summarize: |
| |
| -- Declaration always refers to the syntactic entity that is called |
| -- a declaration. In particular, subprogram declaration |
| -- and package declaration are used to describe the |
| -- syntactic entity that includes the semicolon. |
| |
| -- Specification always refers to the syntactic entity that is called |
| -- a specification. In particular, the terms procedure |
| -- specification, function specification, package |
| -- specification, subprogram specification always refer |
| -- to the syntactic entity that has no semicolon. |
| |
| -- Spec is an informal term, used to refer to the entity |
| -- that is declared by a task declaration, protected |
| -- declaration, generic declaration, subprogram |
| -- declaration or package declaration. |
| |
| -- This convention is followed throughout the GNAT documentation |
| -- both internal and external, and in all error message text. |
| |
| ------------------------ |
| -- Internal Use Nodes -- |
| ------------------------ |
| |
| -- These are Node_Kind settings used in the internal implementation which |
| -- are not logically part of the specification. |
| |
| -- N_Unused_At_Start |
| -- Completely unused entry at the start of the enumeration type. This |
| -- is inserted so that no legitimate value is zero, which helps to get |
| -- better debugging behavior, since zero is a likely uninitialized value). |
| |
| -- N_Unused_At_End |
| -- Completely unused entry at the end of the enumeration type. This is |
| -- handy so that arrays with Node_Kind as the index type have an extra |
| -- entry at the end (see for example the use of the Pchar_Pos_Array in |
| -- Treepr, where the extra entry provides the limit value when dealing with |
| -- the last used entry in the array). |
| |
| ----------------------------------------- |
| -- Note on the settings of Sloc fields -- |
| ----------------------------------------- |
| |
| -- The Sloc field of nodes that come from the source is set by the parser. |
| -- For internal nodes, and nodes generated during expansion the Sloc is |
| -- usually set in the call to the constructor for the node. In general the |
| -- Sloc value chosen for an internal node is the Sloc of the source node |
| -- whose processing is responsible for the expansion. For example, the Sloc |
| -- of an inherited primitive operation is the Sloc of the corresponding |
| -- derived type declaration. |
| |
| -- For the nodes of a generic instantiation, the Sloc value is encoded to |
| -- represent both the original Sloc in the generic unit, and the Sloc of |
| -- the instantiation itself. See Sinput.ads for details. |
| |
| -- Subprogram instances create two callable entities: one is the visible |
| -- subprogram instance, and the other is an anonymous subprogram nested |
| -- within a wrapper package that contains the renamings for the actuals. |
| -- Both of these entities have the Sloc of the defining entity in the |
| -- instantiation node. This simplifies some ASIS queries. |
| |
| ----------------------- |
| -- Field Definitions -- |
| ----------------------- |
| |
| -- In the following node definitions, all fields, both syntactic and |
| -- semantic, are documented. The one exception is in the case of entities |
| -- (defining identifiers, character literals and operator symbols), where |
| -- the usage of the fields depends on the entity kind. Entity fields are |
| -- fully documented in the separate package Einfo. |
| |
| -- In the node definitions, three common sets of fields are abbreviated to |
| -- save both space in the documentation, and also space in the string |
| -- (defined in Tree_Print_Strings) used to print trees. The following |
| -- abbreviations are used: |
| |
| -- Note: the utility program that creates the Treeprs spec (in the file |
| -- xtreeprs.adb) knows about the special fields here, so it must be |
| -- modified if any change is made to these fields. |
| |
| -- "plus fields for binary operator" |
| -- Chars (Name1) Name_Id for the operator |
| -- Left_Opnd (Node2) left operand expression |
| -- Right_Opnd (Node3) right operand expression |
| -- Entity (Node4-Sem) defining entity for operator |
| -- Associated_Node (Node4-Sem) for generic processing |
| -- Do_Overflow_Check (Flag17-Sem) set if overflow check needed |
| -- Has_Private_View (Flag11-Sem) set in generic units. |
| |
| -- "plus fields for unary operator" |
| -- Chars (Name1) Name_Id for the operator |
| -- Right_Opnd (Node3) right operand expression |
| -- Entity (Node4-Sem) defining entity for operator |
| -- Associated_Node (Node4-Sem) for generic processing |
| -- Do_Overflow_Check (Flag17-Sem) set if overflow check needed |
| -- Has_Private_View (Flag11-Sem) set in generic units. |
| |
| -- "plus fields for expression" |
| -- Paren_Count number of parentheses levels |
| -- Etype (Node5-Sem) type of the expression |
| -- Is_Overloaded (Flag5-Sem) >1 type interpretation exists |
| -- Is_Static_Expression (Flag6-Sem) set for static expression |
| -- Raises_Constraint_Error (Flag7-Sem) evaluation raises CE |
| -- Must_Not_Freeze (Flag8-Sem) set if must not freeze |
| -- Do_Range_Check (Flag9-Sem) set if a range check needed |
| -- Has_Dynamic_Length_Check (Flag10-Sem) set if length check inserted |
| -- Has_Dynamic_Range_Check (Flag12-Sem) set if range check inserted |
| -- Assignment_OK (Flag15-Sem) set if modification is OK |
| -- Is_Controlling_Actual (Flag16-Sem) set for controlling argument |
| |
| -- Note: see under (EXPRESSION) for further details on the use of |
| -- the Paren_Count field to record the number of parentheses levels. |
| |
| -- Node_Kind is the type used in the Nkind field to indicate the node kind. |
| -- The actual definition of this type is given later (the reason for this |
| -- is that we want the descriptions ordered by logical chapter in the RM, |
| -- but the type definition is reordered to facilitate the definition of |
| -- some subtype ranges. The individual descriptions of the nodes show how |
| -- the various fields are used in each node kind, as well as providing |
| -- logical names for the fields. Functions and procedures are provided for |
| -- accessing and setting these fields using these logical names. |
| |
| ----------------------- |
| -- Gigi Restrictions -- |
| ----------------------- |
| |
| -- The tree passed to Gigi is more restricted than the general tree form. |
| -- For example, as a result of expansion, most of the tasking nodes can |
| -- never appear. For each node to which either a complete or partial |
| -- restriction applies, a note entitled "Gigi restriction" appears which |
| -- documents the restriction. |
| |
| -- Note that most of these restrictions apply only to trees generated when |
| -- code is being generated, since they involved expander actions that |
| -- destroy the tree. |
| |
| ------------------------ |
| -- Common Flag Fields -- |
| ------------------------ |
| |
| -- The following flag fields appear in all nodes |
| |
| -- Analyzed |
| -- This flag is used to indicate that a node (and all its children have |
| -- been analyzed. It is used to avoid reanalysis of a node that has |
| -- already been analyzed, both for efficiency and functional correctness |
| -- reasons. |
| |
| -- Comes_From_Source |
| -- This flag is set if the node comes directly from an explicit construct |
| -- in the source. It is normally on for any nodes built by the scanner or |
| -- parser from the source program, with the exception that in a few cases |
| -- the parser adds nodes to normalize the representation (in particular |
| -- a null statement is added to a package body if there is no begin/end |
| -- initialization section. |
| -- |
| -- Most nodes inserted by the analyzer or expander are not considered |
| -- as coming from source, so the flag is off for such nodes. In a few |
| -- cases, the expander constructs nodes closely equivalent to nodes |
| -- from the source program (e.g. the allocator built for build-in-place |
| -- case), and the Comes_From_Source flag is deliberately set. |
| |
| -- Error_Posted |
| -- This flag is used to avoid multiple error messages being posted on or |
| -- referring to the same node. This flag is set if an error message |
| -- refers to a node or is posted on its source location, and has the |
| -- effect of inhibiting further messages involving this same node. |
| |
| ------------------------------------ |
| -- Description of Semantic Fields -- |
| ------------------------------------ |
| |
| -- The meaning of the syntactic fields is generally clear from their names |
| -- without any further description, since the names are chosen to |
| -- correspond very closely to the syntax in the reference manual. This |
| -- section describes the usage of the semantic fields, which are used to |
| -- contain additional information determined during semantic analysis. |
| |
| -- ABE_Is_Certain (Flag18-Sem) |
| -- This flag is set in an instantiation node or a call node is determined |
| -- to be sure to raise an ABE. This is used to trigger special handling |
| -- of such cases, particularly in the instantiation case where we avoid |
| -- instantiating the body if this flag is set. This flag is also present |
| -- in an N_Formal_Package_Declaration_Node since formal package |
| -- declarations are treated like instantiations, but it is always set to |
| -- False in this context. |
| |
| -- Accept_Handler_Records (List5-Sem) |
| -- This field is present only in an N_Accept_Alternative node. It is used |
| -- to temporarily hold the exception handler records from an accept |
| -- statement in a selective accept. These exception handlers will |
| -- eventually be placed in the Handler_Records list of the procedure |
| -- built for this accept (see Expand_N_Selective_Accept procedure in |
| -- Exp_Ch9 for further details). |
| |
| -- Access_Types_To_Process (Elist2-Sem) |
| -- Present in N_Freeze_Entity nodes for Incomplete or private types. |
| -- Contains the list of access types which may require specific treatment |
| -- when the nature of the type completion is completely known. An example |
| -- of such treatment is the generation of the associated_final_chain. |
| |
| -- Actions (List1-Sem) |
| -- This field contains a sequence of actions that are associated with the |
| -- node holding the field. See the individual node types for details of |
| -- how this field is used, as well as the description of the specific use |
| -- for a particular node type. |
| |
| -- Activation_Chain_Entity (Node3-Sem) |
| -- This is used in tree nodes representing task activators (blocks, |
| -- subprogram bodies, package declarations, and task bodies). It is |
| -- initially Empty, and then gets set to point to the entity for the |
| -- declared Activation_Chain variable when the first task is declared. |
| -- When tasks are declared in the corresponding declarative region this |
| -- entity is located by name (its name is always _Chain) and the declared |
| -- tasks are added to the chain. Note that N_Extended_Return_Statement |
| -- does not have this attribute, although it does have an activation |
| -- chain. This chain is used to store the tasks temporarily, and is not |
| -- used for activating them. On successful completion of the return |
| -- statement, the tasks are moved to the caller's chain, and the caller |
| -- activates them. |
| |
| -- Acts_As_Spec (Flag4-Sem) |
| -- A flag set in the N_Subprogram_Body node for a subprogram body which |
| -- is acting as its own spec, except in the case of a library level |
| -- subprogram, in which case the flag is set on the parent compilation |
| -- unit node instead (see further description in spec of Lib package). |
| -- ??? Above note about Lib is dubious since lib.ads does not mention |
| -- Acts_As_Spec at all. |
| |
| -- Actual_Designated_Subtype (Node4-Sem) |
| -- Present in N_Free_Statement and N_Explicit_Dereference nodes. If gigi |
| -- needs to known the dynamic constrained subtype of the designated |
| -- object, this attribute is set to that type. This is done for |
| -- N_Free_Statements for access-to-classwide types and access to |
| -- unconstrained packed array types, and for N_Explicit_Dereference when |
| -- the designated type is an unconstrained packed array and the |
| -- dereference is the prefix of a 'Size attribute reference. |
| |
| -- Address_Warning_Posted (Flag18-Sem) |
| -- Present in N_Attribute_Definition nodes. Set to indicate that we have |
| -- posted a warning for the address clause regarding size or alignment |
| -- issues. Used to inhibit multiple redundant messages. |
| |
| -- Aggregate_Bounds (Node3-Sem) |
| -- Present in array N_Aggregate nodes. If the bounds of the aggregate are |
| -- known at compile time, this field points to an N_Range node with those |
| -- bounds. Otherwise Empty. |
| |
| -- All_Others (Flag11-Sem) |
| -- Present in an N_Others_Choice node. This flag is set for an others |
| -- exception where all exceptions are to be caught, even those that are |
| -- not normally handled (in particular the tasking abort signal). This |
| -- is used for translation of the at end handler into a normal exception |
| -- handler. |
| |
| -- Aspect_Rep_Item (Node2-Sem) |
| -- Present in N_Aspect_Specification nodes. Points to the corresponding |
| -- pragma/attribute definition node used to process the aspect. |
| |
| -- Assignment_OK (Flag15-Sem) |
| -- This flag is set in a subexpression node for an object, indicating |
| -- that the associated object can be modified, even if this would not |
| -- normally be permissible (either by direct assignment, or by being |
| -- passed as an out or in-out parameter). This is used by the expander |
| -- for a number of purposes, including initialization of constants and |
| -- limited type objects (such as tasks), setting discriminant fields, |
| -- setting tag values, etc. N_Object_Declaration nodes also have this |
| -- flag defined. Here it is used to indicate that an initialization |
| -- expression is valid, even where it would normally not be allowed |
| -- (e.g. where the type involved is limited). |
| |
| -- Associated_Node (Node4-Sem) |
| -- Present in nodes that can denote an entity: identifiers, character |
| -- literals, operator symbols, expanded names, operator nodes, and |
| -- attribute reference nodes (all these nodes have an Entity field). |
| -- This field is also present in N_Aggregate, N_Selected_Component, and |
| -- N_Extension_Aggregate nodes. This field is used in generic processing |
| -- to create links between the generic template and the generic copy. |
| -- See Sem_Ch12.Get_Associated_Node for full details. Note that this |
| -- field overlaps Entity, which is fine, since, as explained in Sem_Ch12, |
| -- the normal function of Entity is not required at the point where the |
| -- Associated_Node is set. Note also, that in generic templates, this |
| -- means that the Entity field does not necessarily point to an Entity. |
| -- Since the back end is expected to ignore generic templates, this is |
| -- harmless. |
| |
| -- Atomic_Sync_Required (Flag14-Sem) |
| -- This flag is set on a node for which atomic synchronization is |
| -- required for the corresponding reference or modification. |
| |
| -- At_End_Proc (Node1) |
| -- This field is present in an N_Handled_Sequence_Of_Statements node. |
| -- It contains an identifier reference for the cleanup procedure to be |
| -- called. See description of this node for further details. |
| |
| -- Backwards_OK (Flag6-Sem) |
| -- A flag present in the N_Assignment_Statement node. It is used only |
| -- if the type being assigned is an array type, and is set if analysis |
| -- determines that it is definitely safe to do the copy backwards, i.e. |
| -- starting at the highest addressed element. This is the case if either |
| -- the operands do not overlap, or they may overlap, but if they do, |
| -- then the left operand is at a higher address than the right operand. |
| -- |
| -- Note: If neither of the flags Forwards_OK or Backwards_OK is set, it |
| -- means that the front end could not determine that either direction is |
| -- definitely safe, and a runtime check may be required if the backend |
| -- cannot figure it out. If both flags Forwards_OK and Backwards_OK are |
| -- set, it means that the front end can assure no overlap of operands. |
| |
| -- Body_To_Inline (Node3-Sem) |
| -- present in subprogram declarations. Denotes analyzed but unexpanded |
| -- body of subprogram, to be used when inlining calls. Present when the |
| -- subprogram has an Inline pragma and inlining is enabled. If the |
| -- declaration is completed by a renaming_as_body, and the renamed en- |
| -- tity is a subprogram, the Body_To_Inline is the name of that entity, |
| -- which is used directly in later calls to the original subprogram. |
| |
| -- Body_Required (Flag13-Sem) |
| -- A flag that appears in the N_Compilation_Unit node indicating that |
| -- the corresponding unit requires a body. For the package case, this |
| -- indicates that a completion is required. In Ada 95, if the flag is not |
| -- set for the package case, then a body may not be present. In Ada 83, |
| -- if the flag is not set for the package case, then body is optional. |
| -- For a subprogram declaration, the flag is set except in the case where |
| -- a pragma Import or Interface applies, in which case no body is |
| -- permitted (in Ada 83 or Ada 95). |
| |
| -- By_Ref (Flag5-Sem) |
| -- Present in N_Simple_Return_Statement and N_Extended_Return_Statement, |
| -- this flag is set when the returned expression is already allocated on |
| -- the secondary stack and thus the result is passed by reference rather |
| -- than copied another time. |
| |
| -- Check_Address_Alignment (Flag11-Sem) |
| -- A flag present in N_Attribute_Definition clause for a 'Address |
| -- attribute definition. This flag is set if a dynamic check should be |
| -- generated at the freeze point for the entity to which this address |
| -- clause applies. The reason that we need this flag is that we want to |
| -- check for range checks being suppressed at the point where the |
| -- attribute definition clause is given, rather than testing this at the |
| -- freeze point. |
| |
| -- Comes_From_Extended_Return_Statement (Flag18-Sem) |
| -- Present in N_Simple_Return_Statement nodes. True if this node was |
| -- constructed as part of the N_Extended_Return_Statement expansion. |
| |
| -- Compile_Time_Known_Aggregate (Flag18-Sem) |
| -- Present in N_Aggregate nodes. Set for aggregates which can be fully |
| -- evaluated at compile time without raising constraint error. Such |
| -- aggregates can be passed as is the back end without any expansion. |
| -- See Exp_Aggr for specific conditions under which this flag gets set. |
| |
| -- Componentwise_Assignment (Flag14-Sem) |
| -- Present in N_Assignment_Statement nodes. Set for a record assignment |
| -- where all that needs doing is to expand it into component-by-component |
| -- assignments. This is used internally for the case of tagged types with |
| -- rep clauses, where we need to avoid recursion (we don't want to try to |
| -- generate a call to the primitive operation, because this is the case |
| -- where we are compiling the primitive operation). Note that when we are |
| -- expanding component assignments in this case, we never assign the _tag |
| -- field, but we recursively assign components of the parent type. |
| |
| -- Condition_Actions (List3-Sem) |
| -- This field appears in else-if nodes and in the iteration scheme node |
| -- for while loops. This field is only used during semantic processing to |
| -- temporarily hold actions inserted into the tree. In the tree passed |
| -- to gigi, the condition actions field is always set to No_List. For |
| -- details on how this field is used, see the routine Insert_Actions in |
| -- package Exp_Util, and also the expansion routines for the relevant |
| -- nodes. |
| |
| -- Context_Pending (Flag16-Sem) |
| -- This field appears in Compilation_Unit nodes, to indicate that the |
| -- context of the unit is being compiled. Used to detect circularities |
| -- that are not otherwise detected by the loading mechanism. Such |
| -- circularities can occur in the presence of limited and non-limited |
| -- with_clauses that mention the same units. |
| |
| -- Controlling_Argument (Node1-Sem) |
| -- This field is set in procedure and function call nodes if the call |
| -- is a dispatching call (it is Empty for a non-dispatching call). It |
| -- indicates the source of the call's controlling tag. For procedure |
| -- calls, the Controlling_Argument is one of the actuals. For function |
| -- that has a dispatching result, it is an entity in the context of the |
| -- call that can provide a tag, or else it is the tag of the root type |
| -- of the class. It can also specify a tag directly rather than being a |
| -- tagged object. The latter is needed by the implementations of AI-239 |
| -- and AI-260. |
| |
| -- Conversion_OK (Flag14-Sem) |
| -- A flag set on type conversion nodes to indicate that the conversion |
| -- is to be considered as being valid, even though it is the case that |
| -- the conversion is not valid Ada. This is used for attributes Enum_Rep, |
| -- Fixed_Value and Integer_Value, for internal conversions done for |
| -- fixed-point operations, and for certain conversions for calls to |
| -- initialization procedures. If Conversion_OK is set, then Etype must be |
| -- set (the analyzer assumes that Etype has been set). For the case of |
| -- fixed-point operands, it also indicates that the conversion is to be |
| -- direct conversion of the underlying integer result, with no regard to |
| -- the small operand. |
| |
| -- Corresponding_Aspect (Node3-Sem) |
| -- Present in N_Pragma node. Used to point back to the source aspect from |
| -- the corresponding pragma. This field is Empty for source pragmas. |
| |
| -- Corresponding_Body (Node5-Sem) |
| -- This field is set in subprogram declarations, package declarations, |
| -- entry declarations of protected types, and in generic units. It points |
| -- to the defining entity for the corresponding body (NOT the node for |
| -- the body itself). |
| |
| -- Corresponding_Formal_Spec (Node3-Sem) |
| -- This field is set in subprogram renaming declarations, where it points |
| -- to the defining entity for a formal subprogram in the case where the |
| -- renaming corresponds to a generic formal subprogram association in an |
| -- instantiation. The field is Empty if the renaming does not correspond |
| -- to such a formal association. |
| |
| -- Corresponding_Generic_Association (Node5-Sem) |
| -- This field is defined for object declarations and object renaming |
| -- declarations. It is set for the declarations within an instance that |
| -- map generic formals to their actuals. If set, the field points to |
| -- a generic_association which is the original parent of the expression |
| -- or name appearing in the declaration. This simplifies ASIS queries. |
| |
| -- Corresponding_Integer_Value (Uint4-Sem) |
| -- This field is set in real literals of fixed-point types (it is not |
| -- used for floating-point types). It contains the integer value used |
| -- to represent the fixed-point value. It is also set on the universal |
| -- real literals used to represent bounds of fixed-point base types |
| -- and their first named subtypes. |
| |
| -- Corresponding_Spec (Node5-Sem) |
| -- This field is set in subprogram, package, task, and protected body |
| -- nodes, where it points to the defining entity in the corresponding |
| -- spec. The attribute is also set in N_With_Clause nodes where it points |
| -- to the defining entity for the with'ed spec, and in a subprogram |
| -- renaming declaration when it is a Renaming_As_Body. The field is Empty |
| -- if there is no corresponding spec, as in the case of a subprogram body |
| -- that serves as its own spec. |
| -- |
| -- In Ada 2012, Corresponding_Spec is set on expression functions that |
| -- complete a subprogram declaration. |
| |
| -- Corresponding_Stub (Node3-Sem) |
| -- This field is present in an N_Subunit node. It holds the node in |
| -- the parent unit that is the stub declaration for the subunit. It is |
| -- set when analysis of the stub forces loading of the proper body. If |
| -- expansion of the proper body creates new declarative nodes, they are |
| -- inserted at the point of the corresponding_stub. |
| |
| -- Dcheck_Function (Node5-Sem) |
| -- This field is present in an N_Variant node, It references the entity |
| -- for the discriminant checking function for the variant. |
| |
| -- Default_Expression (Node5-Sem) |
| -- This field is Empty if there is no default expression. If there is a |
| -- simple default expression (one with no side effects), then this field |
| -- simply contains a copy of the Expression field (both point to the tree |
| -- for the default expression). Default_Expression is used for |
| -- conformance checking. |
| |
| -- Default_Storage_Pool (Node3-Sem) |
| -- This field is present in N_Compilation_Unit_Aux nodes. It is set to a |
| -- copy of Opt.Default_Pool at the end of the compilation unit. See |
| -- package Opt for details. This is used for inheriting the |
| -- Default_Storage_Pool in child units. |
| |
| -- Discr_Check_Funcs_Built (Flag11-Sem) |
| -- This flag is present in N_Full_Type_Declaration nodes. It is set when |
| -- discriminant checking functions are constructed. The purpose is to |
| -- avoid attempting to set these functions more than once. |
| |
| -- Do_Accessibility_Check (Flag13-Sem) |
| -- This flag is set on N_Parameter_Specification nodes to indicate |
| -- that an accessibility check is required for the parameter. It is |
| -- not yet decided who takes care of this check (TBD ???). |
| |
| -- Do_Discriminant_Check (Flag13-Sem) |
| -- This flag is set on N_Selected_Component nodes to indicate that a |
| -- discriminant check is required using the discriminant check routine |
| -- associated with the selector. The actual check is generated by the |
| -- expander when processing selected components. |
| |
| -- Do_Division_Check (Flag13-Sem) |
| -- This flag is set on a division operator (/ mod rem) to indicate |
| -- that a zero divide check is required. The actual check is dealt |
| -- with by the backend (all the front end does is to set the flag). |
| |
| -- Do_Length_Check (Flag4-Sem) |
| -- This flag is set in an N_Assignment_Statement, N_Op_And, N_Op_Or, |
| -- N_Op_Xor, or N_Type_Conversion node to indicate that a length check |
| -- is required. It is not determined who deals with this flag (???). |
| |
| -- Do_Overflow_Check (Flag17-Sem) |
| -- This flag is set on an operator where an overflow check is required on |
| -- the operation. The actual check is dealt with by the backend (all the |
| -- front end does is to set the flag). The other cases where this flag is |
| -- used is on a Type_Conversion node and for attribute reference nodes. |
| -- For a type conversion, it means that the conversion is from one base |
| -- type to another, and the value may not fit in the target base type. |
| -- See also the description of Do_Range_Check for this case. The only |
| -- attribute references which use this flag are Pred and Succ, where it |
| -- means that the result should be checked for going outside the base |
| -- range. Note that this flag is not set for modular types. This flag is |
| -- also set on if and case expression nodes if we are operating in either |
| -- MINIMIZED or ELIMINATED overflow checking mode (to make sure that we |
| -- properly process overflow checking for dependent expressions). |
| |
| -- Do_Range_Check (Flag9-Sem) |
| -- This flag is set on an expression which appears in a context where a |
| -- range check is required. The target type is clear from the context. |
| -- The contexts in which this flag can appear are the following: |
| |
| -- Right side of an assignment. In this case the target type is |
| -- taken from the left side of the assignment, which is referenced |
| -- by the Name of the N_Assignment_Statement node. |
| |
| -- Subscript expressions in an indexed component. In this case the |
| -- target type is determined from the type of the array, which is |
| -- referenced by the Prefix of the N_Indexed_Component node. |
| |
| -- Argument expression for a parameter, appearing either directly in |
| -- the Parameter_Associations list of a call or as the Expression of an |
| -- N_Parameter_Association node that appears in this list. In either |
| -- case, the check is against the type of the formal. Note that the |
| -- flag is relevant only in IN and IN OUT parameters, and will be |
| -- ignored for OUT parameters, where no check is required in the call, |
| -- and if a check is required on the return, it is generated explicitly |
| -- with a type conversion. |
| |
| -- Initialization expression for the initial value in an object |
| -- declaration. In this case the Do_Range_Check flag is set on |
| -- the initialization expression, and the check is against the |
| -- range of the type of the object being declared. |
| |
| -- The expression of a type conversion. In this case the range check is |
| -- against the target type of the conversion. See also the use of |
| -- Do_Overflow_Check on a type conversion. The distinction is that the |
| -- overflow check protects against a value that is outside the range of |
| -- the target base type, whereas a range check checks that the |
| -- resulting value (which is a value of the base type of the target |
| -- type), satisfies the range constraint of the target type. |
| |
| -- Note: when a range check is required in contexts other than those |
| -- listed above (e.g. in a return statement), an additional type |
| -- conversion node is introduced to represent the required check. |
| |
| -- Do_Storage_Check (Flag17-Sem) |
| -- This flag is set in an N_Allocator node to indicate that a storage |
| -- check is required for the allocation, or in an N_Subprogram_Body node |
| -- to indicate that a stack check is required in the subprogram prolog. |
| -- The N_Allocator case is handled by the routine that expands the call |
| -- to the runtime routine. The N_Subprogram_Body case is handled by the |
| -- backend, and all the semantics does is set the flag. |
| |
| -- Do_Tag_Check (Flag13-Sem) |
| -- This flag is set on an N_Assignment_Statement, N_Function_Call, |
| -- N_Procedure_Call_Statement, N_Type_Conversion, |
| -- N_Simple_Return_Statement, or N_Extended_Return_Statement |
| -- node to indicate that the tag check can be suppressed. It is not |
| -- yet decided how this flag is used (TBD ???). |
| |
| -- Elaborate_Present (Flag4-Sem) |
| -- This flag is set in the N_With_Clause node to indicate that pragma |
| -- Elaborate pragma appears for the with'ed units. |
| |
| -- Elaborate_All_Desirable (Flag9-Sem) |
| -- This flag is set in the N_With_Clause mode to indicate that the static |
| -- elaboration processing has determined that an Elaborate_All pragma is |
| -- desirable for correct elaboration for this unit. |
| |
| -- Elaborate_All_Present (Flag14-Sem) |
| -- This flag is set in the N_With_Clause node to indicate that a |
| -- pragma Elaborate_All pragma appears for the with'ed units. |
| |
| -- Elaborate_Desirable (Flag11-Sem) |
| -- This flag is set in the N_With_Clause mode to indicate that the static |
| -- elaboration processing has determined that an Elaborate pragma is |
| -- desirable for correct elaboration for this unit. |
| |
| -- Elaboration_Boolean (Node2-Sem) |
| -- This field is present in function and procedure specification nodes. |
| -- If set, it points to the entity for a Boolean flag that must be tested |
| -- for certain calls to check for access before elaboration. See body of |
| -- Sem_Elab for further details. This field is Empty if no elaboration |
| -- boolean is required. |
| |
| -- Else_Actions (List3-Sem) |
| -- This field is present in if expression nodes. During code |
| -- expansion we use the Insert_Actions procedure (in Exp_Util) to insert |
| -- actions at an appropriate place in the tree to get elaborated at the |
| -- right time. For if expressions, we have to be sure that the actions |
| -- for the Else branch are only elaborated if the condition is False. |
| -- The Else_Actions field is used as a temporary parking place for |
| -- these actions. The final tree is always rewritten to eliminate the |
| -- need for this field, so in the tree passed to Gigi, this field is |
| -- always set to No_List. |
| |
| -- Enclosing_Variant (Node2-Sem) |
| -- This field is present in the N_Variant node and identifies the Node_Id |
| -- corresponding to the immediately enclosing variant when the variant is |
| -- nested, and N_Empty otherwise. Set during semantic processing of the |
| -- variant part of a record type. |
| |
| -- Entity (Node4-Sem) |
| -- Appears in all direct names (identifiers, character literals, and |
| -- operator symbols), as well as expanded names, and attributes that |
| -- denote entities, such as 'Class. Points to entity for corresponding |
| -- defining occurrence. Set after name resolution. For identifiers in a |
| -- WITH list, the corresponding defining occurrence is in a separately |
| -- compiled file, and Entity must be set by the library Load procedure. |
| -- |
| -- Note: During name resolution, the value in Entity may be temporarily |
| -- incorrect (e.g. during overload resolution, Entity is initially set to |
| -- the first possible correct interpretation, and then later modified if |
| -- necessary to contain the correct value after resolution). |
| -- |
| -- Note: This field overlaps Associated_Node, which is used during |
| -- generic processing (see Sem_Ch12 for details). Note also that in |
| -- generic templates, this means that the Entity field does not always |
| -- point to an Entity. Since the back end is expected to ignore generic |
| -- templates, this is harmless. |
| -- |
| -- Note: This field also appears in N_Attribute_Definition_Clause nodes. |
| -- It is used only for stream attributes definition clauses. In this |
| -- case, it denotes a (possibly dummy) subprogram entity that is declared |
| -- conceptually at the point of the clause. Thus the visibility of the |
| -- attribute definition clause (in the sense of 8.3(23) as amended by |
| -- AI-195) can be checked by testing the visibility of that subprogram. |
| -- |
| -- Note: Normally the Entity field of an identifier points to the entity |
| -- for the corresponding defining identifier, and hence the Chars field |
| -- of an identifier will match the Chars field of the entity. However, |
| -- there is no requirement that these match, and there are obscure cases |
| -- of generated code where they do not match. |
| |
| -- Note: Ada 2012 aspect specifications require additional links between |
| -- identifiers and various attributes. These attributes can be of |
| -- arbitrary types, and the entity field of identifiers that denote |
| -- aspects must be used to store arbitrary expressions for later semantic |
| -- checks. See section on aspect specifications for details. |
| |
| -- Entity_Or_Associated_Node (Node4-Sem) |
| -- A synonym for both Entity and Associated_Node. Used by convention in |
| -- the code when referencing this field in cases where it is not known |
| -- whether the field contains an Entity or an Associated_Node. |
| |
| -- Etype (Node5-Sem) |
| -- Appears in all expression nodes, all direct names, and all entities. |
| -- Points to the entity for the related type. Set after type resolution. |
| -- Normally this is the actual subtype of the expression. However, in |
| -- certain contexts such as the right side of an assignment, subscripts, |
| -- arguments to calls, returned value in a function, initial value etc. |
| -- it is the desired target type. In the event that this is different |
| -- from the actual type, the Do_Range_Check flag will be set if a range |
| -- check is required. Note: if the Is_Overloaded flag is set, then Etype |
| -- points to an essentially arbitrary choice from the possible set of |
| -- types. |
| |
| -- Exception_Junk (Flag8-Sem) |
| -- This flag is set in a various nodes appearing in a statement sequence |
| -- to indicate that the corresponding node is an artifact of the |
| -- generated code for exception handling, and should be ignored when |
| -- analyzing the control flow of the relevant sequence of statements |
| -- (e.g. to check that it does not end with a bad return statement). |
| |
| -- Exception_Label (Node5-Sem) |
| -- Appears in N_Push_xxx_Label nodes. Points to the entity of the label |
| -- to be used for transforming the corresponding exception into a goto, |
| -- or contains Empty, if this exception is not to be transformed. Also |
| -- appears in N_Exception_Handler nodes, where, if set, it indicates |
| -- that there may be a local raise for the handler, so that expansion |
| -- to allow a goto is required (and this field contains the label for |
| -- this goto). See Exp_Ch11.Expand_Local_Exception_Handlers for details. |
| |
| -- Expansion_Delayed (Flag11-Sem) |
| -- Set on aggregates and extension aggregates that need a top-down rather |
| -- than bottom-up expansion. Typically aggregate expansion happens bottom |
| -- up. For nested aggregates the expansion is delayed until the enclosing |
| -- aggregate itself is expanded, e.g. in the context of a declaration. To |
| -- delay it we set this flag. This is done to avoid creating a temporary |
| -- for each level of a nested aggregates, and also to prevent the |
| -- premature generation of constraint checks. This is also a requirement |
| -- if we want to generate the proper attachment to the internal |
| -- finalization lists (for record with controlled components). Top down |
| -- expansion of aggregates is also used for in-place array aggregate |
| -- assignment or initialization. When the full context is known, the |
| -- target of the assignment or initialization is used to generate the |
| -- left-hand side of individual assignment to each sub-component. |
| |
| -- First_Inlined_Subprogram (Node3-Sem) |
| -- Present in the N_Compilation_Unit node for the main program. Points |
| -- to a chain of entities for subprograms that are to be inlined. The |
| -- Next_Inlined_Subprogram field of these entities is used as a link |
| -- pointer with Empty marking the end of the list. This field is Empty |
| -- if there are no inlined subprograms or inlining is not active. |
| |
| -- First_Named_Actual (Node4-Sem) |
| -- Present in procedure call statement and function call nodes, and also |
| -- in Intrinsic nodes. Set during semantic analysis to point to the first |
| -- named parameter where parameters are ordered by declaration order (as |
| -- opposed to the actual order in the call which may be different due to |
| -- named associations). Note: this field points to the explicit actual |
| -- parameter itself, not the N_Parameter_Association node (its parent). |
| |
| -- First_Real_Statement (Node2-Sem) |
| -- Present in N_Handled_Sequence_Of_Statements node. Normally set to |
| -- Empty. Used only when declarations are moved into the statement part |
| -- of a construct as a result of wrapping an AT END handler that is |
| -- required to cover the declarations. In this case, this field is used |
| -- to remember the location in the statements list of the first real |
| -- statement, i.e. the statement that used to be first in the statement |
| -- list before the declarations were prepended. |
| |
| -- First_Subtype_Link (Node5-Sem) |
| -- Present in N_Freeze_Entity node for an anonymous base type that is |
| -- implicitly created by the declaration of a first subtype. It points |
| -- to the entity for the first subtype. |
| |
| -- Float_Truncate (Flag11-Sem) |
| -- A flag present in type conversion nodes. This is used for float to |
| -- integer conversions where truncation is required rather than rounding. |
| -- Note that Gigi does not handle type conversions from real to integer |
| -- with rounding (see Expand_N_Type_Conversion). |
| |
| -- Forwards_OK (Flag5-Sem) |
| -- A flag present in the N_Assignment_Statement node. It is used only |
| -- if the type being assigned is an array type, and is set if analysis |
| -- determines that it is definitely safe to do the copy forwards, i.e. |
| -- starting at the lowest addressed element. This is the case if either |
| -- the operands do not overlap, or they may overlap, but if they do, |
| -- then the left operand is at a lower address than the right operand. |
| -- |
| -- Note: If neither of the flags Forwards_OK or Backwards_OK is set, it |
| -- means that the front end could not determine that either direction is |
| -- definitely safe, and a runtime check may be required if the backend |
| -- cannot figure it out. If both flags Forwards_OK and Backwards_OK are |
| -- set, it means that the front end can assure no overlap of operands. |
| |
| -- From_Aspect_Specification (Flag13-Sem) |
| -- Processing of aspect specifications typically results in insertion in |
| -- the tree of corresponding pragma or attribute definition clause nodes. |
| -- These generated nodes have the From_Aspect_Specification flag set to |
| -- indicate that they came from aspect specifications originally. |
| |
| -- From_At_End (Flag4-Sem) |
| -- This flag is set on an N_Raise_Statement node if it corresponds to |
| -- the reraise statement generated as the last statement of an AT END |
| -- handler when SJLJ exception handling is active. It is used to stop |
| -- a bogus violation of restriction (No_Exception_Propagation), bogus |
| -- because if the restriction is set, the reraise is not generated. |
| |
| -- From_At_Mod (Flag4-Sem) |
| -- This flag is set on the attribute definition clause node that is |
| -- generated by a transformation of an at mod phrase in a record |
| -- representation clause. This is used to give slightly different (Ada 83 |
| -- compatible) semantics to such a clause, namely it is used to specify a |
| -- minimum acceptable alignment for the base type and all subtypes. In |
| -- Ada 95 terms, the actual alignment of the base type and all subtypes |
| -- must be a multiple of the given value, and the representation clause |
| -- is considered to be type specific instead of subtype specific. |
| |
| -- From_Default (Flag6-Sem) |
| -- This flag is set on the subprogram renaming declaration created in an |
| -- instance for a formal subprogram, when the formal is declared with a |
| -- box, and there is no explicit actual. If the flag is present, the |
| -- declaration is treated as an implicit reference to the formal in the |
| -- ali file. |
| |
| -- Generic_Parent (Node5-Sem) |
| -- Generic_Parent is defined on declaration nodes that are instances. The |
| -- value of Generic_Parent is the generic entity from which the instance |
| -- is obtained. Generic_Parent is also defined for the renaming |
| -- declarations and object declarations created for the actuals in an |
| -- instantiation. The generic parent of such a declaration is the |
| -- corresponding generic association in the Instantiation node. |
| |
| -- Generic_Parent_Type (Node4-Sem) |
| -- Generic_Parent_Type is defined on Subtype_Declaration nodes for the |
| -- actuals of formal private and derived types. Within the instance, the |
| -- operations on the actual are those inherited from the parent. For a |
| -- formal private type, the parent type is the generic type itself. The |
| -- Generic_Parent_Type is also used in an instance to determine whether a |
| -- private operation overrides an inherited one. |
| |
| -- Handler_List_Entry (Node2-Sem) |
| -- This field is present in N_Object_Declaration nodes. It is set only |
| -- for the Handler_Record entry generated for an exception in zero cost |
| -- exception handling mode. It references the corresponding item in the |
| -- handler list, and is used to delete this entry if the corresponding |
| -- handler is deleted during optimization. For further details on why |
| -- this is required, see Exp_Ch11.Remove_Handler_Entries. |
| |
| -- Has_Dereference_Action (Flag13-Sem) |
| -- This flag is present in N_Explicit_Dereference nodes. It is set to |
| -- indicate that the expansion has aready produced a call to primitive |
| -- Dereference of a System.Checked_Pools.Checked_Pool implementation. |
| -- Such dereference actions are produced for debugging purposes. |
| |
| -- Has_Dynamic_Length_Check (Flag10-Sem) |
| -- This flag is present in all expression nodes. It is set to indicate |
| -- that one of the routines in unit Checks has generated a length check |
| -- action which has been inserted at the flagged node. This is used to |
| -- avoid the generation of duplicate checks. |
| |
| -- Has_Dynamic_Range_Check (Flag12-Sem) |
| -- This flag is present in N_Subtype_Declaration nodes and on all |
| -- expression nodes. It is set to indicate that one of the routines in |
| -- unit Checks has generated a range check action which has been inserted |
| -- at the flagged node. This is used to avoid the generation of duplicate |
| -- checks. Why does this occur on N_Subtype_Declaration nodes, what does |
| -- it mean in that context??? |
| |
| -- Has_Local_Raise (Flag8-Sem) |
| -- Present in exception handler nodes. Set if the handler can be entered |
| -- via a local raise that gets transformed to a goto statement. This will |
| -- always be set if Local_Raise_Statements is non-empty, but can also be |
| -- set as a result of generation of N_Raise_xxx nodes, or flags set in |
| -- nodes requiring generation of back end checks. |
| |
| -- Has_No_Elaboration_Code (Flag17-Sem) |
| -- A flag that appears in the N_Compilation_Unit node to indicate whether |
| -- or not elaboration code is present for this unit. It is initially set |
| -- true for subprogram specs and bodies and for all generic units and |
| -- false for non-generic package specs and bodies. Gigi may set the flag |
| -- in the non-generic package case if it determines that no elaboration |
| -- code is generated. Note that this flag is not related to the |
| -- Is_Preelaborated status, there can be preelaborated packages that |
| -- generate elaboration code, and non-preelaborated packages which do |
| -- not generate elaboration code. |
| |
| -- Has_Pragma_Suppress_All (Flag14-Sem) |
| -- This flag is set in an N_Compilation_Unit node if the Suppress_All |
| -- pragma appears anywhere in the unit. This accommodates the rather |
| -- strange placement rules of other compilers (DEC permits it at the |
| -- end of a unit, and Rational allows it as a program unit pragma). We |
| -- allow it anywhere at all, and consider it equivalent to a pragma |
| -- Suppress (All_Checks) appearing at the start of the configuration |
| -- pragmas for the unit. |
| |
| -- Has_Private_View (Flag11-Sem) |
| -- A flag present in generic nodes that have an entity, to indicate that |
| -- the node has a private type. Used to exchange private and full |
| -- declarations if the visibility at instantiation is different from the |
| -- visibility at generic definition. |
| |
| -- Has_Relative_Deadline_Pragma (Flag9-Sem) |
| -- A flag present in N_Subprogram_Body and N_Task_Definition nodes to |
| -- flag the presence of a pragma Relative_Deadline. |
| |
| -- Has_Self_Reference (Flag13-Sem) |
| -- Present in N_Aggregate and N_Extension_Aggregate. Indicates that one |
| -- of the expressions contains an access attribute reference to the |
| -- enclosing type. Such a self-reference can only appear in default- |
| -- initialized aggregate for a record type. |
| |
| -- Has_Storage_Size_Pragma (Flag5-Sem) |
| -- A flag present in an N_Task_Definition node to flag the presence of a |
| -- Storage_Size pragma. |
| |
| -- Has_Wide_Character (Flag11-Sem) |
| -- Present in string literals, set if any wide character (i.e. character |
| -- code outside the Character range but within Wide_Character range) |
| -- appears in the string. Used to implement pragma preference rules. |
| |
| -- Has_Wide_Wide_Character (Flag13-Sem) |
| -- Present in string literals, set if any wide character (i.e. character |
| -- code outside the Wide_Character range) appears in the string. Used to |
| -- implement pragma preference rules. |
| |
| -- Header_Size_Added (Flag11-Sem) |
| -- Present in N_Attribute_Reference nodes, set only for attribute |
| -- Max_Size_In_Storage_Elements. The flag indicates that the size of the |
| -- hidden list header used by the runtime finalization support has been |
| -- added to the size of the prefix. The flag also prevents the infinite |
| -- expansion of the same attribute in the said context. |
| |
| -- Hidden_By_Use_Clause (Elist4-Sem) |
| -- An entity list present in use clauses that appear within |
| -- instantiations. For the resolution of local entities, entities |
| -- introduced by these use clauses have priority over global ones, and |
| -- outer entities must be explicitly hidden/restored on exit. |
| |
| -- Implicit_With (Flag16-Sem) |
| -- This flag is set in the N_With_Clause node that is implicitly |
| -- generated for runtime units that are loaded by the expander, and also |
| -- for package System, if it is loaded implicitly by a use of the |
| -- 'Address or 'Tag attribute. ???There are other implicit with clauses |
| -- as well. |
| |
| -- Implicit_With_From_Instantiation (Flag12-Sem) |
| -- Set in N_With_Clause nodes from generic instantiations. |
| |
| -- Import_Interface_Present (Flag16-Sem) |
| -- This flag is set in an Interface or Import pragma if a matching |
| -- pragma of the other kind is also present. This is used to avoid |
| -- generating some unwanted error messages. |
| |
| -- Includes_Infinities (Flag11-Sem) |
| -- This flag is present in N_Range nodes. It is set for the range of |
| -- unconstrained float types defined in Standard, which include not only |
| -- the given range of values, but also legitimately can include infinite |
| -- values. This flag is false for any float type for which an explicit |
| -- range is given by the programmer, even if that range is identical to |
| -- the range for Float. |
| |
| -- Inherited_Discriminant (Flag13-Sem) |
| -- This flag is present in N_Component_Association nodes. It indicates |
| -- that a given component association in an extension aggregate is the |
| -- value obtained from a constraint on an ancestor. Used to prevent |
| -- double expansion when the aggregate has expansion delayed. |
| |
| -- Instance_Spec (Node5-Sem) |
| -- This field is present in generic instantiation nodes, and also in |
| -- formal package declaration nodes (formal package declarations are |
| -- treated in a manner very similar to package instantiations). It points |
| -- to the node for the spec of the instance, inserted as part of the |
| -- semantic processing for instantiations in Sem_Ch12. |
| |
| -- Is_Accessibility_Actual (Flag13-Sem) |
| -- Present in N_Parameter_Association nodes. True if the parameter is |
| -- an extra actual that carries the accessibility level of the actual |
| -- for an access parameter, in a function that dispatches on result and |
| -- is called in a dispatching context. Used to prevent a formal/actual |
| -- mismatch when the call is rewritten as a dispatching call. |
| |
| -- Is_Asynchronous_Call_Block (Flag7-Sem) |
| -- A flag set in a Block_Statement node to indicate that it is the |
| -- expansion of an asynchronous entry call. Such a block needs cleanup |
| -- handler to assure that the call is cancelled. |
| |
| -- Is_Boolean_Aspect (Flag16-Sem) |
| -- Present in N_Aspect_Specification node. Set if the aspect is for a |
| -- boolean aspect (i.e. Aspect_Id is in Boolean_Aspect subtype). |
| |
| -- Is_Component_Left_Opnd (Flag13-Sem) |
| -- Is_Component_Right_Opnd (Flag14-Sem) |
| -- Present in concatenation nodes, to indicate that the corresponding |
| -- operand is of the component type of the result. Used in resolving |
| -- concatenation nodes in instances. |
| |
| -- Is_Delayed_Aspect (Flag14-Sem) |
| -- Present in N_Pragma and N_Attribute_Definition_Clause nodes which |
| -- come from aspect specifications, where the evaluation of the aspect |
| -- must be delayed to the freeze point. This flag is also set True in |
| -- the corresponding N_Aspect_Specification node. |
| |
| -- Is_Controlling_Actual (Flag16-Sem) |
| -- This flag is set on in an expression that is a controlling argument in |
| -- a dispatching call. It is off in all other cases. See Sem_Disp for |
| -- details of its use. |
| |
| -- Is_Dynamic_Coextension (Flag18-Sem) |
| -- Present in allocator nodes, to indicate that this is an allocator |
| -- for an access discriminant of a dynamically allocated object. The |
| -- coextension must be deallocated and finalized at the same time as |
| -- the enclosing object. |
| |
| -- Is_Entry_Barrier_Function (Flag8-Sem) |
| -- This flag is set in an N_Subprogram_Body node which is the expansion |
| -- of an entry barrier from a protected entry body. It is used for the |
| -- circuitry checking for incorrect use of Current_Task. |
| |
| -- Is_Expanded_Build_In_Place_Call (Flag11-Sem) |
| -- This flag is set in an N_Function_Call node to indicate that the extra |
| -- actuals to support a build-in-place style of call have been added to |
| -- the call. |
| |
| -- Is_Finalization_Wrapper (Flag9-Sem); |
| -- This flag is present in N_Block_Statement nodes. It is set when the |
| -- block acts as a wrapper of a handled construct which has controlled |
| -- objects. The wrapper prevents interference between exception handlers |
| -- and At_End handlers. |
| |
| -- Is_In_Discriminant_Check (Flag11-Sem) |
| -- This flag is present in a selected component, and is used to indicate |
| -- that the reference occurs within a discriminant check. The |
| -- significance is that optimizations based on assuming that the |
| -- discriminant check has a correct value cannot be performed in this |
| -- case (or the discriminant check may be optimized away!) |
| |
| -- Is_Machine_Number (Flag11-Sem) |
| -- This flag is set in an N_Real_Literal node to indicate that the value |
| -- is a machine number. This avoids some unnecessary cases of converting |
| -- real literals to machine numbers. |
| |
| -- Is_Null_Loop (Flag16-Sem) |
| -- This flag is set in an N_Loop_Statement node if the corresponding loop |
| -- can be determined to be null at compile time. This is used to remove |
| -- the loop entirely at expansion time. |
| |
| -- Is_Overloaded (Flag5-Sem) |
| -- A flag present in all expression nodes. Used temporarily during |
| -- overloading determination. The setting of this flag is not relevant |
| -- once overloading analysis is complete. |
| |
| -- Is_Power_Of_2_For_Shift (Flag13-Sem) |
| -- A flag present only in N_Op_Expon nodes. It is set when the |
| -- exponentiation is of the form 2 ** N, where the type of N is an |
| -- unsigned integral subtype whose size does not exceed the size of |
| -- Standard_Integer (i.e. a type that can be safely converted to |
| -- Natural), and the exponentiation appears as the right operand of an |
| -- integer multiplication or an integer division where the dividend is |
| -- unsigned. It is also required that overflow checking is off for both |
| -- the exponentiation and the multiply/divide node. If this set of |
| -- conditions holds, and the flag is set, then the division or |
| -- multiplication can be (and is) converted to a shift. |
| |
| -- Is_Prefixed_Call (Flag17-Sem) |
| -- This flag is set in a selected component within a generic unit, if |
| -- it resolves to a prefixed call to a primitive operation. The flag |
| -- is used to prevent accidental overloadings in an instance, when a |
| -- primitive operation and a private record component may be homographs. |
| |
| -- Is_Protected_Subprogram_Body (Flag7-Sem) |
| -- A flag set in a Subprogram_Body block to indicate that it is the |
| -- implementation of a protected subprogram. Such a body needs cleanup |
| -- handler to make sure that the associated protected object is unlocked |
| -- when the subprogram completes. |
| |
| -- Is_Static_Coextension (Flag14-Sem) |
| -- Present in N_Allocator nodes. Set if the allocator is a coextension |
| -- of an object allocated on the stack rather than the heap. |
| |
| -- Is_Static_Expression (Flag6-Sem) |
| -- Indicates that an expression is a static expression (RM 4.9). See spec |
| -- of package Sem_Eval for full details on the use of this flag. |
| |
| -- Is_Subprogram_Descriptor (Flag16-Sem) |
| -- Present in N_Object_Declaration, and set only for the object |
| -- declaration generated for a subprogram descriptor in fast exception |
| -- mode. See Exp_Ch11 for details of use. |
| |
| -- Is_Task_Allocation_Block (Flag6-Sem) |
| -- A flag set in a Block_Statement node to indicate that it is the |
| -- expansion of a task allocator, or the allocator of an object |
| -- containing tasks. Such a block requires a cleanup handler to call |
| -- Expunge_Unactivated_Tasks to complete any tasks that have been |
| -- allocated but not activated when the allocator completes abnormally. |
| |
| -- Is_Task_Master (Flag5-Sem) |
| -- A flag set in a Subprogram_Body, Block_Statement or Task_Body node to |
| -- indicate that the construct is a task master (i.e. has declared tasks |
| -- or declares an access to a task type). |
| |
| -- Itype (Node1-Sem) |
| -- Used in N_Itype_Reference node to reference an itype for which it is |
| -- important to ensure that it is defined. See description of this node |
| -- for further details. |
| |
| -- Kill_Range_Check (Flag11-Sem) |
| -- Used in an N_Unchecked_Type_Conversion node to indicate that the |
| -- result should not be subjected to range checks. This is used for the |
| -- implementation of Normalize_Scalars. |
| |
| -- Label_Construct (Node2-Sem) |
| -- Used in an N_Implicit_Label_Declaration node. Refers to an N_Label, |
| -- N_Block_Statement or N_Loop_Statement node to which the label |
| -- declaration applies. This is not currently used in the compiler |
| -- itself, but it is useful in the implementation of ASIS queries. |
| -- This field is left empty for the special labels generated as part |
| -- of expanding raise statements with a local exception handler. |
| |
| -- Library_Unit (Node4-Sem) |
| -- In a stub node, Library_Unit points to the compilation unit node of |
| -- the corresponding subunit. |
| -- |
| -- In a with clause node, Library_Unit points to the spec of the with'ed |
| -- unit. |
| -- |
| -- In a compilation unit node, the usage depends on the unit type: |
| -- |
| -- For a library unit body, Library_Unit points to the compilation unit |
| -- node of the corresponding spec, unless it's a subprogram body with |
| -- Acts_As_Spec set, in which case it points to itself. |
| -- |
| -- For a spec, Library_Unit points to the compilation unit node of the |
| -- corresponding body, if present. The body will be present if the spec |
| -- is or contains generics that we needed to instantiate. Similarly, the |
| -- body will be present if we needed it for inlining purposes. Thus, if |
| -- we have a spec/body pair, both of which are present, they point to |
| -- each other via Library_Unit. |
| -- |
| -- For a subunit, Library_Unit points to the compilation unit node of |
| -- the parent body. |
| -- |
| -- Note that this field is not used to hold the parent pointer for child |
| -- unit (which might in any case need to use it for some other purpose as |
| -- described above). Instead for a child unit, implicit with's are |
| -- generated for all parents. |
| |
| -- Local_Raise_Statements (Elist1) |
| -- This field is present in exception handler nodes. It is set to |
| -- No_Elist in the normal case. If there is at least one raise statement |
| -- which can potentially be handled as a local raise, then this field |
| -- points to a list of raise nodes, which are calls to a routine to raise |
| -- an exception. These are raise nodes which can be optimized into gotos |
| -- if the handler turns out to meet the conditions which permit this |
| -- transformation. Note that this does NOT include instances of the |
| -- N_Raise_xxx_Error nodes since the transformation of these nodes is |
| -- handled by the back end (using the N_Push/N_Pop mechanism). |
| |
| -- Loop_Actions (List2-Sem) |
| -- A list present in Component_Association nodes in array aggregates. |
| -- Used to collect actions that must be executed within the loop because |
| -- they may need to be evaluated anew each time through. |
| |
| -- Limited_View_Installed (Flag18-Sem) |
| -- Present in With_Clauses and in package specifications. If set on |
| -- with_clause, it indicates that this clause has created the current |
| -- limited view of the designated package. On a package specification, it |
| -- indicates that the limited view has already been created because the |
| -- package is mentioned in a limited_with_clause in the closure of the |
| -- unit being compiled. |
| |
| -- Local_Raise_Not_OK (Flag7-Sem) |
| -- Present in N_Exception_Handler nodes. Set if the handler contains |
| -- a construct (reraise statement, or call to subprogram in package |
| -- GNAT.Current_Exception) that makes the handler unsuitable as a target |
| -- for a local raise (one that could otherwise be converted to a goto). |
| |
| -- Must_Be_Byte_Aligned (Flag14-Sem) |
| -- This flag is present in N_Attribute_Reference nodes. It can be set |
| -- only for the Address and Unrestricted_Access attributes. If set it |
| -- means that the object for which the address/access is given must be on |
| -- a byte (more accurately a storage unit) boundary. If necessary, a copy |
| -- of the object is to be made before taking the address (this copy is in |
| -- the current scope on the stack frame). This is used for certain cases |
| -- of code generated by the expander that passes parameters by address. |
| -- |
| -- The reason the copy is not made by the front end is that the back end |
| -- has more information about type layout and may be able to (but is not |
| -- guaranteed to) prevent making unnecessary copies. |
| |
| -- Must_Not_Freeze (Flag8-Sem) |
| -- A flag present in all expression nodes. Normally expressions cause |
| -- freezing as described in the RM. If this flag is set, then this is |
| -- inhibited. This is used by the analyzer and expander to label nodes |
| -- that are created by semantic analysis or expansion and which must not |
| -- cause freezing even though they normally would. This flag is also |
| -- present in an N_Subtype_Indication node, since we also use these in |
| -- calls to Freeze_Expression. |
| |
| -- Next_Entity (Node2-Sem) |
| -- Present in defining identifiers, defining character literals and |
| -- defining operator symbols (i.e. in all entities). The entities of a |
| -- scope are chained, and this field is used as the forward pointer for |
| -- this list. See Einfo for further details. |
| |
| -- Next_Exit_Statement (Node3-Sem) |
| -- Present in N_Exit_Statement nodes. The exit statements for a loop are |
| -- chained (in reverse order of appearance) from the First_Exit_Statement |
| -- field of the E_Loop entity for the loop. Next_Exit_Statement points to |
| -- the next entry on this chain (Empty = end of list). |
| |
| -- Next_Implicit_With (Node3-Sem) |
| -- Present in N_With_Clause. Part of a chain of with_clauses generated |
| -- in rtsfind to indicate implicit dependencies on predefined units. Used |
| -- to prevent multiple with_clauses for the same unit in a given context. |
| -- A postorder traversal of the tree whose nodes are units and whose |
| -- links are with_clauses defines the order in which Inspector must |
| -- examine a compiled unit and its full context. This ordering ensures |
| -- that any subprogram call is examined after the subprogram declaration |
| -- has been seen. |
| |
| -- Next_Named_Actual (Node4-Sem) |
| -- Present in parameter association node. Set during semantic analysis to |
| -- point to the next named parameter, where parameters are ordered by |
| -- declaration order (as opposed to the actual order in the call, which |
| -- may be different due to named associations). Not that this field |
| -- points to the explicit actual parameter itself, not to the |
| -- N_Parameter_Association node (its parent). |
| |
| -- Next_Pragma (Node1-Sem) |
| -- Present in N_Pragma nodes. Used to create a linked list of pragma |
| -- nodes. Currently used for two purposes: |
| -- |
| -- Create a list of linked Check_Policy pragmas. The head of this list |
| -- is stored in Opt.Check_Policy_List (which has further details). |
| -- |
| -- Used by processing for Pre/Postcondition pragmas to store a list of |
| -- pragmas associated with the spec of a subprogram (see Sem_Prag for |
| -- details). |
| |
| -- Next_Rep_Item (Node5-Sem) |
| -- Present in pragma nodes, attribute definition nodes, enumeration rep |
| -- clauses, record rep clauses, aspect specification nodes. Used to link |
| -- representation items that apply to an entity. See full description of |
| -- First_Rep_Item field in Einfo for further details. |
| |
| -- Next_Use_Clause (Node3-Sem) |
| -- While use clauses are active during semantic processing, they are |
| -- chained from the scope stack entry, using Next_Use_Clause as a link |
| -- pointer, with Empty marking the end of the list. The head pointer is |
| -- in the scope stack entry (First_Use_Clause). At the end of semantic |
| -- processing (i.e. when Gigi sees the tree, the contents of this field |
| -- is undefined and should not be read). |
| |
| -- No_Ctrl_Actions (Flag7-Sem) |
| -- Present in N_Assignment_Statement to indicate that no finalize nor |
| -- adjust should take place on this assignment even though the rhs is |
| -- controlled. This is used in init procs and aggregate expansions where |
| -- the generated assignments are more initialisations than real |
| -- assignments. |
| |
| -- No_Elaboration_Check (Flag14-Sem) |
| -- Present in N_Function_Call and N_Procedure_Call_Statement. Indicates |
| -- that no elaboration check is needed on the call, because it appears in |
| -- the context of a local Suppress pragma. This is used on calls within |
| -- task bodies, where the actual elaboration checks are applied after |
| -- analysis, when the local scope stack is not present. |
| |
| -- No_Entities_Ref_In_Spec (Flag8-Sem) |
| -- Present in N_With_Clause nodes. Set if the with clause is on the |
| -- package or subprogram spec where the main unit is the corresponding |
| -- body, and no entities of the with'ed unit are referenced by the spec |
| -- (an entity may still be referenced in the body, so this flag is used |
| -- to generate the proper message (see Sem_Util.Check_Unused_Withs for |
| -- full details) |
| |
| -- No_Initialization (Flag13-Sem) |
| -- Present in N_Object_Declaration and N_Allocator to indicate that the |
| -- object must not be initialized (by Initialize or call to an init |
| -- proc). This is needed for controlled aggregates. When the Object |
| -- declaration has an expression, this flag means that this expression |
| -- should not be taken into account (needed for in place initialization |
| -- with aggregates). |
| |
| -- No_Minimize_Eliminate (Flag17-Sem) |
| -- This flag is present in membership operator nodes (N_In/N_Not_In). |
| -- It is used to indicate that processing for extended overflow checking |
| -- modes is not required (this is used to prevent infinite recursion). |
| |
| -- No_Truncation (Flag17-Sem) |
| -- Present in N_Unchecked_Type_Conversion node. This flag has an effect |
| -- only if the RM_Size of the source is greater than the RM_Size of the |
| -- target for scalar operands. Normally in such a case we truncate some |
| -- higher order bits of the source, and then sign/zero extend the result |
| -- to form the output value. But if this flag is set, then we do not do |
| -- any truncation, so for example, if an 8 bit input is converted to 5 |
| -- bit result which is in fact stored in 8 bits, then the high order |
| -- three bits of the target result will be copied from the source. This |
| -- is used for properly setting out of range values for use by pragmas |
| -- Initialize_Scalars and Normalize_Scalars. |
| |
| -- Original_Discriminant (Node2-Sem) |
| -- Present in identifiers. Used in references to discriminants that |
| -- appear in generic units. Because the names of the discriminants may be |
| -- different in an instance, we use this field to recover the position of |
| -- the discriminant in the original type, and replace it with the |
| -- discriminant at the same position in the instantiated type. |
| |
| -- Original_Entity (Node2-Sem) |
| -- Present in numeric literals. Used to denote the named number that has |
| -- been constant-folded into the given literal. If literal is from |
| -- source, or the result of some other constant-folding operation, then |
| -- Original_Entity is empty. This field is needed to handle properly |
| -- named numbers in generic units, where the Associated_Node field |
| -- interferes with the Entity field, making it impossible to preserve the |
| -- original entity at the point of instantiation (ASIS problem). |
| |
| -- Others_Discrete_Choices (List1-Sem) |
| -- When a case statement or variant is analyzed, the semantic checks |
| -- determine the actual list of choices that correspond to an others |
| -- choice. This list is materialized for later use by the expander and |
| -- the Others_Discrete_Choices field of an N_Others_Choice node points to |
| -- this materialized list of choices, which is in standard format for a |
| -- list of discrete choices, except that of course it cannot contain an |
| -- N_Others_Choice entry. |
| |
| -- Parameter_List_Truncated (Flag17-Sem) |
| -- Present in N_Function_Call and N_Procedure_Call_Statement nodes. Set |
| -- (for OpenVMS ports of GNAT only) if the parameter list is truncated as |
| -- a result of a First_Optional_Parameter specification in an |
| -- Import_Function, Import_Procedure, or Import_Valued_Procedure pragma. |
| -- The truncation is done by the expander by removing trailing parameters |
| -- from the argument list, in accordance with the set of rules allowing |
| -- such parameter removal. In particular, parameters can be removed |
| -- working from the end of the parameter list backwards up to and |
| -- including the entry designated by First_Optional_Parameter in the |
| -- Import pragma. Parameters can be removed if they are implicit and the |
| -- default value is a known-at-compile-time value, including the use of |
| -- the Null_Parameter attribute, or if explicit parameter values are |
| -- present that match the corresponding defaults. |
| |
| -- Parent_Spec (Node4-Sem) |
| -- For a library unit that is a child unit spec (package or subprogram |
| -- declaration, generic declaration or instantiation, or library level |
| -- rename, this field points to the compilation unit node for the parent |
| -- package specification. This field is Empty for library bodies (the |
| -- parent spec in this case can be found from the corresponding spec). |
| |
| -- Premature_Use (Node5-Sem) |
| -- Present in N_Incomplete_Type_Declaration node. Used for improved |
| -- error diagnostics: if there is a premature usage of an incomplete |
| -- type, a subsequently generated error message indicates the position |
| -- of its full declaration. |
| |
| -- Present_Expr (Uint3-Sem) |
| -- Present in an N_Variant node. This has a meaningful value only after |
| -- Gigi has back annotated the tree with representation information. At |
| -- this point, it contains a reference to a gcc expression that depends |
| -- on the values of one or more discriminants. Give a set of discriminant |
| -- values, this expression evaluates to False (zero) if variant is not |
| -- present, and True (non-zero) if it is present. See unit Repinfo for |
| -- further details on gigi back annotation. This field is used during |
| -- ASIS processing (data decomposition annex) to determine if a field is |
| -- present or not. |
| |
| -- Print_In_Hex (Flag13-Sem) |
| -- Set on an N_Integer_Literal node to indicate that the value should be |
| -- printed in hexadecimal in the sprint listing. Has no effect on |
| -- legality or semantics of program, only on the displayed output. This |
| -- is used to clarify output from the packed array cases. |
| |
| -- Procedure_To_Call (Node2-Sem) |
| -- Present in N_Allocator, N_Free_Statement, N_Simple_Return_Statement, |
| -- and N_Extended_Return_Statement nodes. References the entity for the |
| -- declaration of the procedure to be called to accomplish the required |
| -- operation (i.e. for the Allocate procedure in the case of N_Allocator |
| -- and N_Simple_Return_Statement and N_Extended_Return_Statement (for |
| -- allocating the return value), and for the Deallocate procedure in the |
| -- case of N_Free_Statement. |
| |
| -- Raises_Constraint_Error (Flag7-Sem) |
| -- Set on an expression whose evaluation will definitely fail constraint |
| -- error check. In the case of static expressions, this flag must be set |
| -- accurately (and if it is set, the expression is typically illegal |
| -- unless it appears as a non-elaborated branch of a short-circuit form). |
| -- For a non-static expression, this flag may be set whenever an |
| -- expression (e.g. an aggregate) is known to raise constraint error. If |
| -- set, the expression definitely will raise CE if elaborated at runtime. |
| -- If not set, the expression may or may not raise CE. In other words, on |
| -- static expressions, the flag is set accurately, on non-static |
| -- expressions it is set conservatively. |
| |
| -- Redundant_Use (Flag13-Sem) |
| -- Present in nodes that can appear as an operand in a use clause or use |
| -- type clause (identifiers, expanded names, attribute references). Set |
| -- to indicate that a use is redundant (and therefore need not be undone |
| -- on scope exit). |
| |
| -- Renaming_Exception (Node2-Sem) |
| -- Present in N_Exception_Declaration node. Used to point back to the |
| -- exception renaming for an exception declared within a subprogram. |
| -- What happens is that an exception declared in a subprogram is moved |
| -- to the library level with a unique name, and the original exception |
| -- becomes a renaming. This link from the library level exception to the |
| -- renaming declaration allows registering of the proper exception name. |
| |
| -- Return_Statement_Entity (Node5-Sem) |
| -- Present in N_Simple_Return_Statement and N_Extended_Return_Statement. |
| -- Points to an E_Return_Statement representing the return statement. |
| |
| -- Return_Object_Declarations (List3) |
| -- Present in N_Extended_Return_Statement. Points to a list initially |
| -- containing a single N_Object_Declaration representing the return |
| -- object. We use a list (instead of just a pointer to the object decl) |
| -- because Analyze wants to insert extra actions on this list. |
| |
| -- Rounded_Result (Flag18-Sem) |
| -- Present in N_Type_Conversion, N_Op_Divide and N_Op_Multiply nodes. |
| -- Used in the fixed-point cases to indicate that the result must be |
| -- rounded as a result of the use of the 'Round attribute. Also used for |
| -- integer N_Op_Divide nodes to indicate that the result should be |
| -- rounded to the nearest integer (breaking ties away from zero), rather |
| -- than truncated towards zero as usual. These rounded integer operations |
| -- are the result of expansion of rounded fixed-point divide, conversion |
| -- and multiplication operations. |
| |
| -- SCIL_Entity (Node4-Sem) |
| -- Present in SCIL nodes. Used to reference the tagged type associated |
| -- with the SCIL node. |
| |
| -- SCIL_Controlling_Tag (Node5-Sem) |
| -- Present in N_SCIL_Dispatching_Call nodes. Used to reference the |
| -- controlling tag of a dispatching call. |
| |
| -- SCIL_Tag_Value (Node5-Sem) |
| -- Present in N_SCIL_Membership_Test nodes. Used to reference the tag |
| -- value that is being tested. |
| |
| -- SCIL_Target_Prim (Node2-Sem) |
| -- Present in N_SCIL_Dispatching_Call nodes. Used to reference the tagged |
| -- type primitive associated with the SCIL node. |
| |
| -- Scope (Node3-Sem) |
| -- Present in defining identifiers, defining character literals and |
| -- defining operator symbols (i.e. in all entities). The entities of a |
| -- scope all use this field to reference the corresponding scope entity. |
| -- See Einfo for further details. |
| |
| -- Shift_Count_OK (Flag4-Sem) |
| -- A flag present in shift nodes to indicate that the shift count is |
| -- known to be in range, i.e. is in the range from zero to word length |
| -- minus one. If this flag is not set, then the shift count may be |
| -- outside this range, i.e. larger than the word length, and the code |
| -- must ensure that such shift counts give the appropriate result. |
| |
| -- Source_Type (Node1-Sem) |
| -- Used in an N_Validate_Unchecked_Conversion node to point to the |
| -- source type entity for the unchecked conversion instantiation |
| -- which gigi must do size validation for. |
| |
| -- Split_PPC (Flag17) |
| -- When a Pre or Post aspect specification is processed, it is broken |
| -- into AND THEN sections. The left most section has Split_PPC set to |
| -- False, indicating that it is the original specification (e.g. for |
| -- posting errors). For other sections, Split_PPC is set to True. |
| -- This flag is set in both the N_Aspect_Specification node itself, |
| -- and in the pragma which is generated from this node. |
| |
| -- Storage_Pool (Node1-Sem) |
| -- Present in N_Allocator, N_Free_Statement, N_Simple_Return_Statement, |
| -- and N_Extended_Return_Statement nodes. References the entity for the |
| -- storage pool to be used for the allocate or free call or for the |
| -- allocation of the returned value from function. Empty indicates that |
| -- the global default pool is to be used. Note that in the case |
| -- of a return statement, this field is set only if the function returns |
| -- value of a type whose size is not known at compile time on the |
| -- secondary stack. |
| |
| -- Suppress_Assignment_Checks (Flag18-Sem) |
| -- Used in generated N_Assignment_Statement nodes to suppress predicate |
| -- and range checks in cases where the generated code knows that the |
| -- value being assigned is in range and satisfies any predicate. Also |
| -- can be set in N_Object_Declaration nodes, to similarly suppress any |
| -- checks on the initializing value. |
| |
| -- Suppress_Loop_Warnings (Flag17-Sem) |
| -- Used in N_Loop_Statement node to indicate that warnings within the |
| -- body of the loop should be suppressed. This is set when the range |
| -- of a FOR loop is known to be null, or is probably null (loop would |
| -- only execute if invalid values are present). |
| |
| -- Target_Type (Node2-Sem) |
| -- Used in an N_Validate_Unchecked_Conversion node to point to the target |
| -- type entity for the unchecked conversion instantiation which gigi must |
| -- do size validation for. |
| |
| -- Then_Actions (List3-Sem) |
| -- This field is present in if expression nodes. During code expansion |
| -- we use the Insert_Actions procedure (in Exp_Util) to insert actions |
| -- at an appropriate place in the tree to get elaborated at the right |
| -- time. For if expressions, we have to be sure that the actions for |
| -- for the Then branch are only elaborated if the condition is True. |
| -- The Then_Actions field is used as a temporary parking place for |
| -- these actions. The final tree is always rewritten to eliminate the |
| -- need for this field, so in the tree passed to Gigi, this field is |
| -- always set to No_List. |
| |
| -- Treat_Fixed_As_Integer (Flag14-Sem) |
| -- This flag appears in operator nodes for divide, multiply, mod and rem |
| -- on fixed-point operands. It indicates that the operands are to be |
| -- treated as integer values, ignoring small values. This flag is only |
| -- set as a result of expansion of fixed-point operations. Typically a |
| -- fixed-point multiplication in the source generates subsidiary |
| -- multiplication and division operations that work with the underlying |
| -- integer values and have this flag set. Note that this flag is not |
| -- needed on other arithmetic operations (add, neg, subtract etc.) since |
| -- in these cases it is always the case that fixed is treated as integer. |
| -- The Etype field MUST be set if this flag is set. The analyzer knows to |
| -- leave such nodes alone, and whoever makes them must set the correct |
| -- Etype value. |
| |
| -- TSS_Elist (Elist3-Sem) |
| -- Present in N_Freeze_Entity nodes. Holds an element list containing |
| -- entries for each TSS (type support subprogram) associated with the |
| -- frozen type. The elements of the list are the entities for the |
| -- subprograms (see package Exp_TSS for further details). Set to No_Elist |
| -- if there are no type support subprograms for the type or if the freeze |
| -- node is not for a type. |
| |
| -- Unreferenced_In_Spec (Flag7-Sem) |
| -- Present in N_With_Clause nodes. Set if the with clause is on the |
| -- package or subprogram spec where the main unit is the corresponding |
| -- body, and is not referenced by the spec (it may still be referenced by |
| -- the body, so this flag is used to generate the proper message (see |
| -- Sem_Util.Check_Unused_Withs for details) |
| |
| -- Used_Operations (Elist5-Sem) |
| -- Present in N_Use_Type_Clause nodes. Holds the list of operations that |
| -- are made potentially use-visible by the clause. Simplifies processing |
| -- on exit from the scope of the use_type_clause, in particular in the |
| -- case of Use_All_Type, when those operations several scopes. |
| |
| -- Was_Originally_Stub (Flag13-Sem) |
| -- This flag is set in the node for a proper body that replaces stub. |
| -- During the analysis procedure, stubs in some situations get rewritten |
| -- by the corresponding bodies, and we set this flag to remember that |
| -- this happened. Note that it is not good enough to rely on the use of |
| -- Original_Node here because of the case of nested instantiations where |
| -- the substituted node can be copied. |
| |
| -- Withed_Body (Node1-Sem) |
| -- Present in N_With_Clause nodes. Set if the unit in whose context |
| -- the with_clause appears instantiates a generic contained in the |
| -- library unit of the with_clause and as a result loads its body. |
| -- Used for a more precise unit traversal for CodePeer. |
| |
| -------------------------------------------------- |
| -- Note on Use of End_Label and End_Span Fields -- |
| -------------------------------------------------- |
| |
| -- Several constructs have end lines: |
| |
| -- Loop Statement end loop [loop_IDENTIFIER]; |
| -- Package Specification end [[PARENT_UNIT_NAME .] IDENTIFIER] |
| -- Task Definition end [task_IDENTIFIER] |
| -- Protected Definition end [protected_IDENTIFIER] |
| -- Protected Body end [protected_IDENTIFIER] |
| |
| -- Block Statement end [block_IDENTIFIER]; |
| -- Subprogram Body end [DESIGNATOR]; |
| -- Package Body end [[PARENT_UNIT_NAME .] IDENTIFIER]; |
| -- Task Body end [task_IDENTIFIER]; |
| -- Accept Statement end [entry_IDENTIFIER]]; |
| -- Entry Body end [entry_IDENTIFIER]; |
| |
| -- If Statement end if; |
| -- Case Statement end case; |
| |
| -- Record Definition end record; |
| -- Enumeration Definition ); |
| |
| -- The End_Label and End_Span fields are used to mark the locations of |
| -- these lines, and also keep track of the label in the case where a label |
| -- is present. |
| |
| -- For the first group above, the End_Label field of the corresponding node |
| -- is used to point to the label identifier. In the case where there is no |
| -- label in the source, the parser supplies a dummy identifier (with |
| -- Comes_From_Source set to False), and the Sloc of this dummy identifier |
| -- marks the location of the token following the END token. |
| |
| -- For the second group, the use of End_Label is similar, but the End_Label |
| -- is found in the N_Handled_Sequence_Of_Statements node. This is done |
| -- simply because in some cases there is no room in the parent node. |
| |
| -- For the third group, there is never any label, and instead of using |
| -- End_Label, we use the End_Span field which gives the location of the |
| -- token following END, relative to the starting Sloc of the construct, |
| -- i.e. add Sloc (Node) + End_Span (Node) to get the Sloc of the IF or CASE |
| -- following the End_Label. |
| |
| -- The record definition case is handled specially, we treat it as though |
| -- it required an optional label which is never present, and so the parser |
| -- always builds a dummy identifier with Comes From Source set False. The |
| -- reason we do this, rather than using End_Span in this case, is that we |
| -- want to generate a cross-ref entry for the end of a record, since it |
| -- represents a scope for name declaration purposes. |
| |
| -- The enumeration definition case is handled in an exactly similar manner, |
| -- building a dummy identifier to get a cross-reference. |
| |
| -- Note: the reason we store the difference as a Uint, instead of storing |
| -- the Source_Ptr value directly, is that Source_Ptr values cannot be |
| -- distinguished from other types of values, and we count on all general |
| -- use fields being self describing. To make things easier for clients, |
| -- note that we provide function End_Location, and procedure |
| -- Set_End_Location to allow access to the logical value (which is the |
| -- Source_Ptr value for the end token). |

| -- 2.3 Identifier -- |
| --------------------- |
| |
| -- IDENTIFIER ::= IDENTIFIER_LETTER {[UNDERLINE] LETTER_OR_DIGIT} |
| -- LETTER_OR_DIGIT ::= IDENTIFIER_LETTER | DIGIT |
| |
| -- An IDENTIFIER shall not be a reserved word |
| |
| -- In the Ada grammar identifiers are the bottom level tokens which have |
| -- very few semantics. Actual program identifiers are direct names. If |
| -- we were being 100% honest with the grammar, then we would have a node |
| -- called N_Direct_Name which would point to an identifier. However, |
| -- that's too many extra nodes, so we just use the N_Identifier node |
| -- directly as a direct name, and it contains the expression fields and |
| -- Entity field that correspond to its use as a direct name. In those |
| -- few cases where identifiers appear in contexts where they are not |
| -- direct names (pragmas, pragma argument associations, attribute |
| -- references and attribute definition clauses), the Chars field of the |
| -- node contains the Name_Id for the identifier name. |
| |
| -- Note: in GNAT, a reserved word can be treated as an identifier in two |
| -- cases. First, an incorrect use of a reserved word as an identifier is |
| -- diagnosed and then treated as a normal identifier. Second, an |
| -- attribute designator of the form of a reserved word (access, delta, |
| -- digits, range) is treated as an identifier. |
| |
| -- Note: The set of letters that is permitted in an identifier depends |
| -- on the character set in use. See package Csets for full details. |
| |
| -- N_Identifier |
| -- Sloc points to identifier |

| |
| -- DECIMAL_LITERAL ::= NUMERAL [.NUMERAL] [EXPONENT] |
| |
| -- NUMERAL ::= DIGIT {[UNDERLINE] DIGIT} |
| |
| -- EXPONENT ::= E [+] NUMERAL | E - NUMERAL |
| |
| -- Decimal literals appear in the tree as either integer literal nodes |
| -- or real literal nodes, depending on whether a period is present. |
| |
| -- Note: literal nodes appear as a result of direct use of literals |
| -- in the source program, and also as the result of evaluating |
| -- expressions at compile time. In the latter case, it is possible |
| -- to construct real literals that have no syntactic representation |
| -- using the standard literal format. Such literals are listed by |
| -- Sprint using the notation [numerator / denominator]. |
| |
| -- Note: the value of an integer literal node created by the front end |
| -- is never outside the range of values of the base type. However, it |
| -- can be the case that the created value is outside the range of the |
| -- particular subtype. This happens in the case of integer overflows |
| -- with checks suppressed. |
| |
| -- N_Integer_Literal |
| -- Sloc points to literal |
| -- Original_Entity (Node2-Sem) If not Empty, holds Named_Number that |
| -- has been constant-folded into its literal value. |
| -- Intval (Uint3) contains integer value of literal |

| -- Sloc points to literal |
| -- Chars (Name1) contains the Name_Id for the identifier |

| -- Entity (Node4-Sem) |
| -- Associated_Node (Node4-Sem) |
| -- Has_Private_View (Flag11-Sem) set in generic units. |
| -- plus fields for expression |
| |
| -- Note: the Entity field will be missing (set to Empty) for character |
| -- literals whose type is Standard.Wide_Character or Standard.Character |
| -- or a type derived from one of these two. In this case the character |
| -- literal stands for its own coding. The reason we take this irregular |
| -- short cut is to avoid the need to build lots of junk defining |
| -- character literal nodes. |
| |
| ------------------------- |
| -- 2.6 String Literal -- |
| ------------------------- |
| |
| -- STRING LITERAL ::= "{STRING_ELEMENT}" |
| |
| -- A STRING_ELEMENT is either a pair of quotation marks ("), or a |
| -- single GRAPHIC_CHARACTER other than a quotation mark. |
| -- |
| -- Is_Folded_In_Parser is True if the parser created this literal by |
| -- folding a sequence of "&" operators. For example, if the source code |
| -- says "aaa" & "bbb" & "ccc", and this produces "aaabbbccc", the flag |
| -- is set. This flag is needed because the parser doesn't know about |
| -- visibility, so the folded result might be wrong, and semantic |
| -- analysis needs to check for that. |
| |
| -- N_String_Literal |
| -- Sloc points to literal |
| -- Strval (Str3) contains Id of string value |
| -- Has_Wide_Character (Flag11-Sem) |

| -- 2.7 Comment -- |
| ------------------ |
| |
| -- A COMMENT starts with two adjacent hyphens and extends up to the |
| -- end of the line. A COMMENT may appear on any line of a program. |
| |
| -- Comments are skipped by the scanner and do not appear in the tree. |
| -- It is possible to reconstruct the position of comments with respect |
| -- to the elements of the tree by using the source position (Sloc) |
| -- pointers that appear in every tree node. |
| |
| ----------------- |
| -- 2.8 Pragma -- |
| ----------------- |
| |
| -- PRAGMA ::= pragma IDENTIFIER |
| -- [(PRAGMA_ARGUMENT_ASSOCIATION {, PRAGMA_ARGUMENT_ASSOCIATION})]; |
| |
| -- Note that a pragma may appear in the tree anywhere a declaration |
| -- or a statement may appear, as well as in some other situations |
| -- which are explicitly documented. |
| |
| -- N_Pragma |
| -- Sloc points to PRAGMA |
| -- Next_Pragma (Node1-Sem) |
| -- Pragma_Argument_Associations (List2) (set to No_List if none) |
| -- Corresponding_Aspect (Node3-Sem) (set to Empty if not present) |
| -- Pragma_Identifier (Node4) |
| -- Next_Rep_Item (Node5-Sem) |
| -- From_Aspect_Specification (Flag13-Sem) |
| -- Is_Delayed_Aspect (Flag14-Sem) |
| -- Import_Interface_Present (Flag16-Sem) |
| -- Split_PPC (Flag17) set if corresponding aspect had Split_PPC set |
| -- Class_Present (Flag6) set if from Aspect with 'Class |
| |
| -- Note: we should have a section on what pragmas are passed on to |
| -- the back end to be processed. This section should note that pragma |
| -- Psect_Object is always converted to Common_Object, but there are |
| -- undoubtedly many other similar notes required ??? |
| |
| -- Note: a utility function Pragma_Name may be applied to pragma nodes |
| -- to conveniently obtain the Chars field of the Pragma_Identifier. |
| |
| -- Note: if From_Aspect_Specification is set, then Sloc points to the |
| -- aspect name, as does the Pragma_Identifier. In this case if the |
| -- pragma has a local name argument (such as pragma Inline), it is |
| -- resolved to point to the specific entity affected by the pragma. |

| |
| -- PRAGMA_ARGUMENT_ASSOCIATION ::= |
| -- [pragma_argument_IDENTIFIER =>] NAME |
| -- | [pragma_argument_IDENTIFIER =>] EXPRESSION |
| |
| -- N_Pragma_Argument_Association |
| -- Sloc points to first token in association |
| -- Chars (Name1) (set to No_Name if no pragma argument identifier) |
| -- Expression (Node3) |
| |
| ------------------------ |
| -- 2.9 Reserved Word -- |
| ------------------------ |
| |
| -- Reserved words are parsed by the scanner, and returned as the |

| |
| -- A defining identifier is an entity, which has additional fields |
| -- depending on the setting of the Ekind field. These additional |
| -- fields are defined (and access subprograms declared) in package |
| -- Einfo. |
| |
| -- Note: N_Defining_Identifier is an extended node whose fields are |
| -- deliberate layed out to match the layout of fields in an ordinary |

| |
| ------------------------------- |
| -- 3.2.2 Subtype Indication -- |
| ------------------------------- |
| |
| -- SUBTYPE_INDICATION ::= SUBTYPE_MARK [CONSTRAINT] |
| |
| -- Note: if no constraint is present, the subtype indication appears |
| -- directly in the tree as a subtype mark. The N_Subtype_Indication |
| -- node is used only if a constraint is present. |
| |
| -- Note: [For Ada 2005 (AI-231)]: Because Ada 2005 extends this rule |
| -- with the null-exclusion part (see AI-231), we had to introduce a new |
| -- attribute in all the parents of subtype_indication nodes to indicate |
| -- if the null-exclusion is present. |

| -- 4.1.4 Attribute Reference -- |
| -------------------------------- |
| |
| -- ATTRIBUTE_REFERENCE ::= PREFIX ' ATTRIBUTE_DESIGNATOR |
| |
| -- Note: the syntax is quite ambiguous at this point. Consider: |
| |
| -- A'Length (X) X is part of the attribute designator |
| -- A'Pos (X) X is an explicit actual parameter of function A'Pos |
| -- A'Class (X) X is the expression of a type conversion |
| |
| -- It would be possible for the parser to distinguish these cases |
| -- by looking at the attribute identifier. However, that would mean |
| -- more work in introducing new implementation defined attributes, |
| -- and also it would mean that special processing for attributes |
| -- would be scattered around, instead of being centralized in the |
| -- semantic routine that handles an N_Attribute_Reference node. |
| -- Consequently, the parser in all the above cases stores the |
| -- expression (X in these examples) as a single element list in |
| -- in the Expressions field of the N_Attribute_Reference node. |
| |
| -- Similarly, for attributes like Max which take two arguments, |
| -- we store the two arguments as a two element list in the |
| -- Expressions field. Of course it is clear at parse time that |
| -- this case is really a function call with an attribute as the |
| -- prefix, but it turns out to be convenient to handle the two |
| -- argument case in a similar manner to the one argument case, |
| -- and indeed in general the parser will accept any number of |
| -- expressions in this position and store them as a list in the |
| -- attribute reference node. This allows for future addition of |
| -- attributes that take more than two arguments. |
| |
| -- Note: named associates are not permitted in function calls where |
| -- the function is an attribute (see RM 6.4(3)) so it is legitimate |
| -- to skip the normal subprogram argument processing. |
| |
| -- Note: for the attributes whose designators are technically keywords, |
| -- i.e. digits, access, delta, range, the Attribute_Name field contains |
| -- the corresponding name, even though no identifier is involved. |
| |
| -- Note: the generated code may contain stream attributes applied to |
| -- limited types for which no stream routines exist officially. In such |
| -- case, the result is to use the stream attribute for the underlying |
| -- full type, or in the case of a protected type, the components |
| -- (including any discriminants) are merely streamed in order. |
| |
| -- See Exp_Attr for a complete description of which attributes are |
| -- passed onto Gigi, and which are handled entirely by the front end. |
| |
| -- Gigi restriction: For the Pos attribute, the prefix cannot be |
| -- a non-standard enumeration type or a nonzero/zero semantics |
| -- boolean type, so the value is simply the stored representation. |
| |
| -- Gigi requirement: For the Mechanism_Code attribute, if the prefix |
| -- references a subprogram that is a renaming, then the front end must |
| -- rewrite the attribute to refer directly to the renamed entity. |
| |
| -- Note: In generated code, the Address and Unrestricted_Access |
| -- attributes can be applied to any expression, and the meaning is |
| -- to create an object containing the value (the object is in the |
| -- current stack frame), and pass the address of this value. If the |
| -- Must_Be_Byte_Aligned flag is set, then the object whose address |
| -- is taken must be on a byte (storage unit) boundary, and if it is |
| -- not (or may not be), then the generated code must create a copy |
| -- that is byte aligned, and pass the address of this copy. |

| |
| -- Note: this structure is used for both record and array aggregates |

| -- makes no attempt to enforce consistency here, so it is up to the |
| -- semantic phase to make sure that the aggregate is consistent (i.e. |
| -- that it is not a "half-and-half" case that mixes record and array |
| -- syntax. In particular, for a record aggregate, the expressions |
| -- field will be set if there are positional associations. |
| |
| -- Note: N_Aggregate is not used for all aggregates; in particular, |
| -- there is a separate node kind for extension aggregates. |
| |
| -- Note: gigi/gcc can handle array aggregates correctly providing that |
| -- they are entirely positional, and the array subtype involved has a |
| -- known at compile time length and is not bit packed, or a convention |
| -- Fortran array with more than one dimension. If these conditions |
| -- are not met, then the front end must translate the aggregate into |
| -- an appropriate set of assignments into a temporary. |
| |
| -- Note: for the record aggregate case, gigi/gcc can handle all cases of |
| -- record aggregates, including those for packed, and rep-claused |
| -- records, and also variant records, providing that there are no |
| -- variable length fields whose size is not known at compile time, and |

| -- an example of an expression). |
| |
| -- Note: the above syntax is that Ada 2012 syntax which restricts |
| -- choice relations to simple expressions to avoid ambiguities in |
| -- some contexts with set membership notation. It has been decided |
| -- that in retrospect, the Ada 95 change allowing general expressions |
| -- in this context was a mistake, so we have reverted to the above |
| -- syntax in Ada 95 and Ada 2005 modes (the restriction to simple |
| -- expressions was there in Ada 83 from the start). |
| |
| ------------------ |
| -- 4.4 Primary -- |
| ------------------ |
| |
| -- PRIMARY ::= |
| -- NUMERIC_LITERAL | null |
| -- | STRING_LITERAL | AGGREGATE |
| -- | NAME | QUALIFIED_EXPRESSION |
| -- | ALLOCATOR | (EXPRESSION) |
| |
| -- Usually there is no explicit node in the tree for primary. Instead |
| -- the constituent (e.g. AGGREGATE) appears directly. There are two |
| -- exceptions. First, there is an explicit node for a null primary. |
| |
| -- N_Null |
| -- Sloc points to NULL |
| -- plus fields for expression |
| |
| -- Second, the case of (EXPRESSION) is handled specially. Ada requires |
| -- that the parser keep track of which subexpressions are enclosed |
| -- in parentheses, and how many levels of parentheses are used. This |
| -- information is required for optimization purposes, and also for |
| -- some semantic checks (e.g. (((1))) in a procedure spec does not |
| -- conform with ((((1)))) in the body). |
| |
| -- The parentheses are recorded by keeping a Paren_Count field in every |
| -- subexpression node (it is actually present in all nodes, but only |
| -- used in subexpression nodes). This count records the number of |
| -- levels of parentheses. If the number of levels in the source exceeds |
| -- the maximum accommodated by this count, then the count is simply left |
| -- at the maximum value. This means that there are some pathological |
| -- cases of failure to detect conformance failures (e.g. an expression |
| -- with 500 levels of parens will conform with one with 501 levels), |
| -- but we do not need to lose sleep over this. |
| |
| -- Historical note: in versions of GNAT prior to 1.75, there was a node |
| -- type N_Parenthesized_Expression used to accurately record unlimited |
| -- numbers of levels of parentheses. However, it turned out to be a |
| -- real nuisance to have to take into account the possible presence of |
| -- this node during semantic analysis, since basically parentheses have |
| -- zero relevance to semantic analysis. |
| |
| -- Note: the level of parentheses always present in things like |
| -- aggregates does not count, only the parentheses in the primary |
| -- (EXPRESSION) affect the setting of the Paren_Count field. |
| |
| -- 2nd Note: the contents of the Expression field must be ignored (i.e. |
| -- treated as though it were Empty) if No_Initialization is set True. |

| -- Note: although the grammar above allows only a range or a subtype |

| -- See also shift operators in section B.2 |
| |
| -- Note on fixed-point operations passed to Gigi: For adding operators, |
| -- the semantics is to treat these simply as integer operations, with |
| -- the small values being ignored (the bounds are already stored in |
| -- units of small, so that constraint checking works as usual). For the |
| -- case of multiply/divide/rem/mod operations, Gigi will only see fixed |
| -- point operands if the Treat_Fixed_As_Integer flag is set and will |
| -- thus treat these nodes in identical manner, ignoring small values. |
| |
| -- Note on overflow handling: When the overflow checking mode is set to |
| -- MINIMIZED or ELIMINATED, nodes for signed arithmetic operations may |
| -- be modified to use a larger type for the operands and result. In |
| -- the case where the computed range exceeds that of Long_Long_Integer, |
| -- and we are running in ELIMINATED mode, the operator node will be |
| -- changed to be a call to the appropriate routine in System.Bignums. |

| -- 4.7 Qualified Expression -- |
| ------------------------------- |
| |
| -- QUALIFIED_EXPRESSION ::= |
| -- SUBTYPE_MARK ' (EXPRESSION) | SUBTYPE_MARK ' AGGREGATE |
| |
| -- Note: the parentheses in the (EXPRESSION) case are deemed to enclose |
| -- the expression, so the Expression field of this node always points |
| -- to a parenthesized expression in this case (i.e. Paren_Count will |
| -- always be non-zero for the referenced expression if it is not an |
| -- aggregate). |
| |
| -- N_Qualified_Expression |

| -- Is_Dynamic_Coextension (Flag18-Sem) |
| -- plus fields for expression |
| |
| -- Note: like all nodes, the N_Allocator has the Comes_From_Source flag. |
| -- This flag has a special function in conjunction with the restriction |
| -- No_Implicit_Heap_Allocations, which will be triggered if this flag |
| -- is not set. This means that if a source allocator is replaced with |
| -- a constructed allocator, the Comes_From_Source flag should be copied |
| -- to the newly created allocator. |

| --------------------------------- |
| -- 5.1 Sequence Of Statements -- |
| --------------------------------- |
| |
| -- SEQUENCE_OF_STATEMENTS ::= STATEMENT {STATEMENT} |
| |
| -- Note: Although the parser will not accept a declaration as a |
| -- statement, the semantic analyzer may insert declarations (e.g. |
| -- declarations of implicit types needed for execution of other |
| -- statements) into a sequence of statements, so the code generator |
| -- should be prepared to accept a declaration where a statement is |
| -- expected. Note also that pragmas can appear as statements. |

| -------------------- |
| |
| -- STATEMENT ::= |
| -- {LABEL} SIMPLE_STATEMENT | {LABEL} COMPOUND_STATEMENT |

| -- There is no explicit node in the tree for a statement. Instead, the |
| -- individual statement appears directly. Labels are treated as a |
| -- kind of statement, i.e. they are linked into a statement list at |
| -- the point they appear, so the labeled statement appears following |

| |
| -- Note: if a range check is required, then the Do_Range_Check flag |
| -- is set in the Expression (right hand side), with the check being |
| -- done against the type of the Name (left hand side). |
| |
| -- Note: the back end places some restrictions on the form of the |
| -- Expression field. If the object being assigned to is Atomic, then |
| -- the Expression may not have the form of an aggregate (since this |
| -- might cause the back end to generate separate assignments). In this |
| -- case the front end must generate an extra temporary and initialize |
| -- this temporary as required (the temporary itself is not atomic). |

| -- end loop [loop_IDENTIFIER]; |
| |
| -- Note: The occurrence of a loop label is not a defining identifier |
| -- but rather a referencing occurrence. The defining occurrence is in |
| -- the implicit label declaration which occurs in the innermost |
| -- enclosing block. |
| |
| -- Note: there is always a loop statement identifier present in |
| -- the tree, even if none was given in the source. In the case where |
| -- no loop identifier is given in the source, the parser creates |
| -- a name of the form _Loop_n, where n is a decimal integer (the |
| -- two underlines ensure that the loop names created in this manner |
| -- do not conflict with any user defined identifiers), and the flag |
| -- Has_Created_Identifier is set to True. The only exception to the |
| -- rule that all loop statement nodes have identifiers occurs for |
| -- loops constructed by the expander, and the semantic analyzer will |
| -- create and supply dummy loop identifiers in these cases. |
| |
| -- N_Loop_Statement |

| |
| -- Note: the parser fills in the Identifier field if there is an |

| -- [block_STATEMENT_IDENTIFIER:] |
| -- [declare |
| -- DECLARATIVE_PART] |
| -- begin |
| -- HANDLED_SEQUENCE_OF_STATEMENTS |
| -- end [block_IDENTIFIER]; |
| |
| -- Note that the occurrence of a block identifier is not a defining |
| -- identifier, but rather a referencing occurrence. The defining |
| -- occurrence is an E_Block entity declared by the implicit label |
| -- declaration which occurs in the innermost enclosing block statement |
| -- or body; the block identifier denotes that E_Block. |
| |
| -- For block statements that come from source code, there is always a |
| -- block statement identifier present in the tree, denoting an |
| -- E_Block. In the case where no block identifier is given in the |
| -- source, the parser creates a name of the form B_n, where n is a |
| -- decimal integer, and the flag Has_Created_Identifier is set to |
| -- True. Blocks constructed by the expander usually have no identifier, |
| -- and no corresponding entity. |
| |
| -- Note: the block statement created for an extended return statement |
| -- has an entity, and this entity is an E_Return_Statement, rather than |
| -- the usual E_Block. |
| |
| -- Note: Exception_Junk is set for the wrapping blocks created during |
| -- local raise optimization (Exp_Ch11.Expand_Local_Exception_Handlers). |
| |
| -- Note: from a control flow viewpoint, a block statement defines an |
| -- extended basic block, i.e. the entry of the block dominates every |
| -- statement in the sequence. When generating new statements with |
| -- exception handlers in the expander at the end of a sequence that |
| -- comes from source code, it can be necessary to wrap them all in a |
| -- block statement in order to expose the implicit control flow to |
| -- gigi and thus prevent it from issuing bogus control flow warnings. |

| -- 6.1 Operator Symbol -- |
| -------------------------- |
| |
| -- OPERATOR_SYMBOL ::= STRING_LITERAL |
| |
| -- Note: the fields of the N_Operator_Symbol node are laid out to |

| -- COMPILATION_UNIT ::= |
| -- CONTEXT_CLAUSE LIBRARY_ITEM |
| -- | CONTEXT_CLAUSE SUBUNIT |
| |
| -- The N_Compilation_Unit node itself represents the above syntax. |
| -- However, there are two additional items not reflected in the above |
| -- syntax. First we have the global declarations that are added by the |
| -- code generator. These are outer level declarations (so they cannot |
| -- be represented as being inside the units). An example is the wrapper |
| -- subprograms that are created to do ABE checking. As always a list of |
| -- declarations can contain actions as well (i.e. statements), and such |
| -- statements are executed as part of the elaboration of the unit. Note |
| -- that all such declarations are elaborated before the library unit. |
| |
| -- Similarly, certain actions need to be elaborated at the completion |
| -- of elaboration of the library unit (notably the statement that sets |
| -- the Boolean flag indicating that elaboration is complete). |
| |
| -- The third item not reflected in the syntax is pragmas that appear |
| -- after the compilation unit. As always pragmas are a problem since |
| -- they are not part of the formal syntax, but can be stuck into the |
| -- source following a set of ad hoc rules, and we have to find an ad |
| -- hoc way of sticking them into the tree. For pragmas that appear |
| -- before the library unit, we just consider them to be part of the |
| -- context clause, and pragmas can appear in the Context_Items list |
| -- of the compilation unit. However, pragmas can also appear after |
| -- the library item. |
| |
| -- To deal with all these problems, we create an auxiliary node for |
| -- a compilation unit, referenced from the N_Compilation_Unit node, |
| -- that contains these items. |

| -- 11.2 Handled Sequence Of Statements -- |

| -- SEQUENCE_OF_STATEMENTS |
| -- [exception |
| -- EXCEPTION_HANDLER |
| -- {EXCEPTION_HANDLER}] |
| -- [at end |
| -- cleanup_procedure_call (param, param, param, ...);] |
| |
| -- The AT END phrase is a GNAT extension to provide for cleanups. It is |
| -- used only internally currently, but is considered to be syntactic. |
| -- At the moment, the only cleanup action allowed is a single call to |
| -- a parameterless procedure, and the Identifier field of the node is |
| -- the procedure to be called. The cleanup action occurs whenever the |
| -- sequence of statements is left for any reason. The possible reasons |
| -- are: |
| -- 1. reaching the end of the sequence |
| -- 2. exit, return, or goto |
| -- 3. exception or abort |
| -- For some back ends, such as gcc with ZCX, "at end" is implemented |
| -- entirely in the back end. In this case, a handled sequence of |
| -- statements with an "at end" cannot also have exception handlers. |
| -- For other back ends, such as gcc with SJLJ and .NET, the |
| -- implementation is split between the front end and back end; the front |
| -- end implements 3, and the back end implements 1 and 2. In this case, |
| -- if there is an "at end", the front end inserts the appropriate |
| -- exception handler, and this handler takes precedence over "at end" |
| -- in case of exception. |
| |
| -- The inserted exception handler is of the form: |
| |
| -- when all others => |
| -- cleanup; |
| -- raise; |
| |
| -- where cleanup is the procedure to be called. The reason we do this is |
| -- so that the front end can handle the necessary entries in the |
| -- exception tables, and other exception handler actions required as |
| -- part of the normal handling for exception handlers. |
| |
| -- The AT END cleanup handler protects only the sequence of statements |
| -- (not the associated declarations of the parent), just like exception |
| -- handlers. The big difference is that the cleanup procedure is called |
| -- on either a normal or an abnormal exit from the statement sequence. |
| |
| -- Note: the list of Exception_Handlers can contain pragmas as well |
| -- as actual handlers. In practice these pragmas can only occur at |
| -- the start of the list, since any pragmas occurring later on will |
| -- be included in the statement list of the corresponding handler. |
| |
| -- Note: although in the Ada syntax, the sequence of statements in |
| -- a handled sequence of statements can only contain statements, we |
| -- allow free mixing of declarations and statements in the resulting |
| -- expanded tree. This is for example used to deal with the case of |
| -- a cleanup procedure that must handle declarations as well as the |
| -- statements of a block. |
| |
| -- N_Handled_Sequence_Of_Statements |
| -- Sloc points to first token of first statement |
| -- Statements (List3) |

| -- Exception_Handlers (List5) (set to No_List if none present) |
| -- At_End_Proc (Node1) (set to Empty if no clean up procedure) |
| -- First_Real_Statement (Node2-Sem) |
| |
| -- Note: the parent always contains a Declarations field which contains |
| -- declarations associated with the handled sequence of statements. This |
| -- is true even in the case of an accept statement (see description of |
| -- the N_Accept_Statement node). |
| |

| |
| -- LOCAL_NAME := |
| -- DIRECT_NAME |
| -- | DIRECT_NAME'ATTRIBUTE_DESIGNATOR |

| -- 13.3 Attribute definition clause -- |

| |
| -- ATTRIBUTE_DEFINITION_CLAUSE ::= |
| -- for LOCAL_NAME'ATTRIBUTE_DESIGNATOR use EXPRESSION; |
| -- | for LOCAL_NAME'ATTRIBUTE_DESIGNATOR use NAME; |
| |
| -- In Ada 83, the expression must be a simple expression and the |
| -- local name must be a direct name. |
| |
| -- Note: the only attribute definition clause that is processed by |
| -- gigi is an address clause. For all other cases, the information |
| -- is extracted by the front end and either results in setting entity |
| -- information, e.g. Esize for the Size clause, or in appropriate |
| -- expansion actions (e.g. in the case of Storage_Size). |
| |
| -- For an address clause, Gigi constructs the appropriate addressing |
| -- code. It also ensures that no aliasing optimizations are made |
| -- for the object for which the address clause appears. |
| |
| -- Note: for an address clause used to achieve an overlay: |
| |
| -- A : Integer; |
| -- B : Integer; |
| -- for B'Address use A'Address; |
| |
| -- the above rule means that Gigi will ensure that no optimizations |
| -- will be made for B that would violate the implementation advice |
| -- of RM 13.3(19). However, this advice applies only to B and not |
| -- to A, which seems unfortunate. The GNAT front end will mark the |
| -- object A as volatile to also prevent unwanted optimization |
| -- assumptions based on no aliasing being made for B. |
| |
| -- N_Attribute_Definition_Clause |
| -- Sloc points to FOR |
| -- Name (Node2) the local name |

| -- to which the aspect applies. |
| |
| ----------------------------------- |
| -- 13.3.1 Aspect Specifications -- |
| ----------------------------------- |
| |
| -- We modify the RM grammar here, the RM grammar is: |
| |
| -- ASPECT_SPECIFICATION ::= |
| -- with ASPECT_MARK [=> ASPECT_DEFINITION] {, |
| -- ASPECT_MARK [=> ASPECT_DEFINITION] } |
| |
| -- ASPECT_MARK ::= aspect_IDENTIFIER['Class] |
| |
| -- ASPECT_DEFINITION ::= NAME | EXPRESSION |
| |
| -- That's inconvenient, since there is no non-terminal name for a single |
| -- entry in the list of aspects. So we use this grammar instead: |
| |
| -- ASPECT_SPECIFICATIONS ::= |
| -- with ASPECT_SPECIFICATION {, ASPECT_SPECIFICATION} |
| |
| -- ASPECT_SPECIFICATION => |
| -- ASPECT_MARK [=> ASPECT_DEFINITION] |
| |
| -- ASPECT_MARK ::= aspect_IDENTIFIER['Class] |
| |
| -- ASPECT_DEFINITION ::= NAME | EXPRESSION |
| |
| -- See separate package Aspects for details on the incorporation of |
| -- these nodes into the tree, and how aspect specifications for a given |
| -- declaration node are associated with that node. |
| |
| -- N_Aspect_Specification |
| -- Sloc points to aspect identifier |
| -- Identifier (Node1) aspect identifier |
| -- Aspect_Rep_Item (Node2-Sem) |
| -- Expression (Node3) Aspect_Definition (set to Empty if none) |
| -- Entity (Node4-Sem) entity to which the aspect applies |
| -- Class_Present (Flag6) Set if 'Class present |
| -- Next_Rep_Item (Node5-Sem) |
| -- Split_PPC (Flag17) Set if split pre/post attribute |
| -- Is_Boolean_Aspect (Flag16-Sem) |
| -- Is_Delayed_Aspect (Flag14-Sem) |
| |
| -- Note: Aspect_Specification is an Ada 2012 feature |
| |
| -- Note: The Identifier serves to identify the aspect involved (it |
| -- is the aspect whose name corresponds to the Chars field). This |
| -- means that the other fields of this identifier are unused, and |
| -- in particular we use the Entity field of this identifier to save |
| -- a copy of the expression for visibility analysis, see spec of |
| -- Sem_Ch13 for full details of this usage. |
| |
| -- Note: When a Pre or Post aspect specification is processed, it is |
| -- broken into AND THEN sections. The left most section has Split_PPC |
| -- set to False, indicating that it is the original specification (e.g. |
| -- for posting errors). For the other sections, Split_PPC is set True. |

| -- B.2 Shift Operators -- |
| -------------------------- |
| |
| -- Calls to the intrinsic shift functions are converted to one of |

| -- operator names. Note that for a given shift operation, one node |
| -- covers all possible types, as for normal operators. |
| |
| -- Note: it is perfectly permissible for the expander to generate |

| -- and parsed in the usual manner. |
| |
| -- Sprint syntax: shift-function-name!(expr, count) |
| |
| -- Note: the Left_Opnd field holds the first argument (the value to |
| -- be shifted). The Right_Opnd field holds the second argument (the |
| -- shift count). The Chars field is the name of the intrinsic function. |

| -- Obsolescent Features -- |
| -------------------------- |
| |
| -- The syntax descriptions and tree nodes for obsolescent features are |

| -- is located in an appropriate chapter (see individual notes). |
| |
| --------------------------- |
| -- J.3 Delta Constraint -- |
| --------------------------- |
| |
| -- Note: the parse routine for this construct is located in section |
| -- 3.5.9 of Par-Ch3, and semantic analysis is in Sem_Ch3, which is |
| -- where delta constraint logically belongs. |
| |
| -- DELTA_CONSTRAINT ::= DELTA static_EXPRESSION [RANGE_CONSTRAINT] |

| -- AT_CLAUSE ::= for DIRECT_NAME use at EXPRESSION; |
| |
| -- Note: the parse routine for this construct is located in Par-Ch13, |
| -- and the semantic analysis is in Sem_Ch13, where at clause logically |
| -- belongs if it were not obsolescent. |
| |
| -- Note: in Ada 83 the expression must be a simple expression |
| |
| -- Gigi restriction: This node never appears, it is rewritten as an |
| -- address attribute definition clause. |
| |
| -- N_At_Clause |
| -- Sloc points to FOR |
| -- Identifier (Node1) |
| -- Expression (Node3) |
| |
| --------------------- |
| -- J.8 Mod clause -- |
| --------------------- |
| |
| -- MOD_CLAUSE ::= at mod static_EXPRESSION; |
| |
| -- Note: the parse routine for this construct is located in Par-Ch13, |
| -- and the semantic analysis is in Sem_Ch13, where mod clause logically |
| -- belongs if it were not obsolescent. |
| |
| -- Note: in Ada 83, the expression must be a simple expression |
| |
| -- Gigi restriction: this node never appears. It is replaced |
| -- by a corresponding Alignment attribute definition clause. |
| |
| -- Note: pragmas can appear before and after the MOD_CLAUSE since |
| -- its name has "clause" in it. This is rather strange, but is quite |
| -- definitely specified. The pragmas before are collected in the |
| -- Pragmas_Before field of the mod clause node itself, and pragmas |
| -- after are simply swallowed up in the list of component clauses. |

| -- Semantic Nodes -- |
| -------------------- |
| |
| -- These semantic nodes are used to hold additional semantic information. |
| -- They are inserted into the tree as a result of semantic processing. |
| -- Although there are no legitimate source syntax constructions that |
| -- correspond directly to these nodes, we need a source syntax for the |
| -- reconstructed tree printed by Sprint, and the node descriptions here |
| -- show this syntax. |
| |
| -------------- |
| -- Contract -- |
| -------------- |
| |
| -- This node is used to hold the various parts of an entry or subprogram |
| -- contract, consisting in pre- and postconditions on the one hand, and |
| -- test-cases on the other hand. |
| |
| -- It is referenced from an entry, a subprogram or a generic subprogram |
| -- entity. |
| |
| -- Sprint syntax: <none> as the node should not appear in the tree, but |
| -- only attached to an entry or [generic] subprogram |
| -- entity. |
| |
| -- N_Contract |
| -- Sloc points to the subprogram's name |
| -- Spec_PPC_List (Node1) (set to Empty if none) |
| -- Spec_CTC_List (Node2) (set to Empty if none) |
| |
| -- Spec_PPC_List points to a list of Precondition and Postcondition |
| -- pragma nodes for preconditions and postconditions declared in the |
| -- spec of the entry/subprogram. The last pragma encountered is at the |
| -- head of this list, so it is in reverse order of textual appearance. |
| -- Note that this includes precondition/postcondition pragmas generated |
| -- to correspond to Pre/Post aspects. |
| |
| -- Spec_CTC_List points to a list of Contract_Case and Test_Case pragma |
| -- nodes for contract-cases and test-cases declared in the spec of the |
| -- entry/subprogram. The last pragma encountered is at the head of this |
| -- list, so it is in reverse order of textual appearance. Note that |
| -- this includes contract-case and test-case pragmas generated from |
| -- Contract_Case and Test_Case aspects. |
| |
| ------------------- |
| -- Expanded_Name -- |
| ------------------- |
| |
| -- The N_Expanded_Name node is used to represent a selected component |
| -- name that has been resolved to an expanded name. The semantic phase |
| -- replaces N_Selected_Component nodes that represent names by the use |
| -- of this node, leaving the N_Selected_Component node used only when |
| -- the prefix is a record or protected type. |
| |
| -- The fields of the N_Expanded_Name node are layed out identically |
| -- to those of the N_Selected_Component node, allowing conversion of |
| -- an expanded name node to a selected component node to be done |
| -- easily, see Sinfo.CN.Change_Selected_Component_To_Expanded_Name. |
| |
| -- There is no special sprint syntax for an expanded name |
| |
| -- N_Expanded_Name |
| -- Sloc points to the period |
| -- Chars (Name1) copy of Chars field of selector name |
| -- Prefix (Node3) |
| -- Selector_Name (Node2) |
| -- Entity (Node4-Sem) |
| -- Associated_Node (Node4-Sem) |
| -- Has_Private_View (Flag11-Sem) set in generic units. |
| -- Redundant_Use (Flag13-Sem) |
| -- Atomic_Sync_Required (Flag14-Sem) |
| -- plus fields for expression |
| |
| ----------------------------- |
| -- Expression with Actions -- |
| ----------------------------- |
| |
| -- This node is created by the analyzer/expander to handle some |
| -- expansion cases, notably short circuit forms where there are |
| -- actions associated with the right-hand side operand. |
| |
| -- The N_Expression_With_Actions node represents an expression with |
| -- an associated set of actions (which are executable statements and |
| -- declarations, as might occur in a handled statement sequence). |
| |
| -- The required semantics is that the set of actions is executed in |
| -- the order in which it appears just before the expression is |
| -- evaluated (and these actions must only be executed if the value |
| -- of the expression is evaluated). The node is considered to be |
| -- a subexpression, whose value is the value of the Expression after |
| -- executing all the actions. |
| |
| -- Note: if the actions contain declarations, then these declarations |
| -- may be referenced within the expression. It is thus appropriate for |
| -- the back-end to create a scope that encompasses the construct (any |
| -- declarations within the actions will definitely not be referenced |
| -- once elaboration of the construct is completed). |
| |
| -- Sprint syntax: do |
| -- action; |
| -- action; |
| -- ... |
| -- action; |
| -- in expression end |
| |
| -- N_Expression_With_Actions |
| -- Actions (List1) |
| -- Expression (Node3) |
| -- plus fields for expression |
| |
| -- Note: the actions list is always non-null, since we would |
| -- never have created this node if there weren't some actions. |
| |
| -------------------- |
| -- Free Statement -- |
| -------------------- |
| |
| -- The N_Free_Statement node is generated as a result of a call to an |
| -- instantiation of Unchecked_Deallocation. The instantiation of this |
| -- generic is handled specially and generates this node directly. |
| |
| -- Sprint syntax: free expression |
| |
| -- N_Free_Statement |
| -- Sloc is copied from the unchecked deallocation call |
| -- Expression (Node3) argument to unchecked deallocation call |
| -- Storage_Pool (Node1-Sem) |
| -- Procedure_To_Call (Node2-Sem) |
| -- Actual_Designated_Subtype (Node4-Sem) |
| |
| -- Note: in the case where a debug source file is generated, the Sloc |
| -- for this node points to the FREE keyword in the Sprint file output. |
| |
| ------------------- |
| -- Freeze Entity -- |
| ------------------- |
| |
| -- This node marks the point in a declarative part at which an entity |
| -- declared therein becomes frozen. The expander places initialization |
| -- procedures for types at those points. Gigi uses the freezing point |
| -- to elaborate entities that may depend on previous private types. |
| |
| -- See the section in Einfo "Delayed Freezing and Elaboration" for |
| -- a full description of the use of this node. |
| |
| -- The Entity field points back to the entity for the type (whose |
| -- Freeze_Node field points back to this freeze node). |
| |
| -- The Actions field contains a list of declarations and statements |
| -- generated by the expander which are associated with the freeze |
| -- node, and are elaborated as though the freeze node were replaced |
| -- by this sequence of actions. |
| |
| -- Note: the Sloc field in the freeze node references a construct |
| -- associated with the freezing point. This is used for posting |
| -- messages in some error/warning situations, e.g. the case where |
| -- a primitive operation of a tagged type is declared too late. |
| |
| -- Sprint syntax: freeze entity-name [ |
| -- freeze actions |
| -- ] |
| |
| -- N_Freeze_Entity |
| -- Sloc points near freeze point (see above special note) |
| -- Entity (Node4-Sem) |
| -- Access_Types_To_Process (Elist2-Sem) (set to No_Elist if none) |
| -- TSS_Elist (Elist3-Sem) (set to No_Elist if no associated TSS's) |
| -- Actions (List1) (set to No_List if no freeze actions) |
| -- First_Subtype_Link (Node5-Sem) (set to Empty if no link) |
| |
| -- The Actions field holds actions associated with the freeze. These |
| -- actions are elaborated at the point where the type is frozen. |
| |
| -- Note: in the case where a debug source file is generated, the Sloc |
| -- for this node points to the FREEZE keyword in the Sprint file output. |
| |
| -------------------------------- |
| -- Implicit Label Declaration -- |
| -------------------------------- |
| |
| -- An implicit label declaration is created for every occurrence of a |
| -- label on a statement or a label on a block or loop. It is chained |
| -- in the declarations of the innermost enclosing block as specified |
| -- in RM section 5.1 (3). |
| |
| -- The Defining_Identifier is the actual identifier for the statement |
| -- identifier. Note that the occurrence of the label is a reference, NOT |
| -- the defining occurrence. The defining occurrence occurs at the head |
| -- of the innermost enclosing block, and is represented by this node. |
| |
| -- Note: from the grammar, this might better be called an implicit |
| -- statement identifier declaration, but the term we choose seems |
| -- friendlier, since at least informally statement identifiers are |
| -- called labels in both cases (i.e. when used in labels, and when |
| -- used as the identifiers of blocks and loops). |
| |
| -- Note: although this is logically a semantic node, since it does not |
| -- correspond directly to a source syntax construction, these nodes are |
| -- actually created by the parser in a post pass done just after parsing |
| -- is complete, before semantic analysis is started (see Par.Labl). |
| |
| -- Sprint syntax: labelname : label; |
| |
| -- N_Implicit_Label_Declaration |
| -- Sloc points to the << of the label |
| -- Defining_Identifier (Node1) |
| -- Label_Construct (Node2-Sem) |
| |
| -- Note: in the case where a debug source file is generated, the Sloc |
| -- for this node points to the label name in the generated declaration. |
| |
| --------------------- |
| -- Itype_Reference -- |
| --------------------- |
| |
| -- This node is used to create a reference to an Itype. The only purpose |
| -- is to make sure the Itype is defined if this is the first reference. |
| |

| -- Raise_xxx_Error -- |
| --------------------- |
| |
| -- One of these nodes is created during semantic analysis to replace |
| -- a node for an expression that is determined to definitely raise |
| -- the corresponding exception. |
| |
| -- The N_Raise_xxx_Error node may also stand alone in place |
| -- of a declaration or statement, in which case it simply causes |
| -- the exception to be raised (i.e. it is equivalent to a raise |
| -- statement that raises the corresponding exception). This use |
| -- is distinguished by the fact that the Etype in this case is |
| -- Standard_Void_Type, In the subexpression case, the Etype is the |
| -- same as the type of the subexpression which it replaces. |
| |
| -- If Condition is empty, then the raise is unconditional. If the |
| -- Condition field is non-empty, it is a boolean expression which |
| -- is first evaluated, and the exception is raised only if the |
| -- value of the expression is True. In the unconditional case, the |
| -- creation of this node is usually accompanied by a warning message |
| -- error. The creation of this node will usually be accompanied by a |
| -- message (unless it appears within the right operand of a short |
| -- circuit form whose left argument is static and decisively |
| -- eliminates elaboration of the raise operation. The condition field |
| -- can ONLY be present when the node is used as a statement form, it |
| -- may NOT be present in the case where the node appears within an |
| -- expression. |
| |
| -- The exception is generated with a message that contains the |
| -- file name and line number, and then appended text. The Reason |
| -- code shows the text to be added. The Reason code is an element |
| -- of the type Types.RT_Exception_Code, and indicates both the |
| -- message to be added, and the exception to be raised (which must |
| -- match the node type). The value is stored by storing a Uint which |
| -- is the Pos value of the enumeration element in this type. |
| |
| -- Gigi restriction: This expander ensures that the type of the |
| -- Condition field is always Standard.Boolean, even if the type |
| -- in the source is some non-standard boolean type. |

| |
| --------------------------------------------- |
| -- Optimization of Exception Raise to Goto -- |
| --------------------------------------------- |
| |
| -- In some cases, the front end will determine that any exception raised |
| -- by the back end for a certain exception should be transformed into a |
| -- goto statement. |
| |
| -- There are three kinds of exceptions raised by the back end (note that |
| -- for this purpose we consider gigi to be part of the back end in the |
| -- gcc case): |
| |
| -- 1. Exceptions resulting from N_Raise_xxx_Error nodes |
| -- 2. Exceptions from checks triggered by Do_xxx_Check flags |
| -- 3. Other cases not specifically marked by the front end |
| |
| -- Normally all such exceptions are translated into calls to the proper |
| -- Rcheck_xx procedure, where xx encodes both the exception to be raised |
| -- and the exception message. |
| |
| -- The front end may determine that for a particular sequence of code, |
| -- exceptions in any of these three categories for a particular builtin |
| -- exception should result in a goto, rather than a call to Rcheck_xx. |
| -- The exact sequence to be generated is: |
| |
| -- Local_Raise (exception'Identity); |
| -- goto Label |
| |
| -- The front end marks such a sequence of code by bracketing it with |
| -- push and pop nodes: |
| |
| -- N_Push_xxx_Label (referencing the label) |
| -- ... |
| -- (code where transformation is expected for exception xxx) |
| -- ... |
| -- N_Pop_xxx_Label |
| |
| -- The use of push/pop reflects the fact that such regions can properly |
| -- nest, and one special case is a subregion in which no transformation |
| -- is allowed. Such a region is marked by a N_Push_xxx_Label node whose |
| -- Exception_Label field is Empty. |

| -- Reference -- |
| --------------- |
| |
| -- For a number of purposes, we need to construct references to objects. |
| -- These references are subsequently treated as normal access values. |
| -- An example is the construction of the parameter block passed to a |
| -- task entry. The N_Reference node is provided for this purpose. It is |
| -- similar in effect to the use of the Unrestricted_Access attribute, |
| -- and like Unrestricted_Access can be applied to objects which would |
| -- not be valid prefixes for the Unchecked_Access attribute (e.g. |
| -- objects which are not aliased, and slices). In addition it can be |
| -- applied to composite type values as well as objects, including string |
| -- values and aggregates. |
| |
| -- Note: we use the Prefix field for this expression so that the |
| -- resulting node can be treated using common code with the attribute |
| -- nodes for the 'Access and related attributes. Logically it would make |
| -- more sense to call it an Expression field, but then we would have to |
| -- special case the treatment of the N_Reference node. |
| |
| -- Note: evaluating a N_Reference node is guaranteed to yield a non-null |
| -- value at run time. Therefore, it is valid to set Is_Known_Non_Null on |
| -- a temporary initialized to a N_Reference node in order to eliminate |
| -- superfluous access checks. |
| |
| -- Sprint syntax: prefix'reference |
| |
| -- N_Reference |

| -- SCIL Nodes -- |
| ----------------- |
| |
| -- SCIL nodes are special nodes added to the tree when the CodePeer |
| -- mode is active. They help the CodePeer backend to locate nodes that |
| -- require special processing. |
| |
| -- Major documentation on the general design of the SCIL interface, and |
| -- in particular detailed description of these nodes is missing and is |
| -- to be supplied in the future, when the design has finalized ??? |
| |
| -- Meanwhile these nodes should be considered in experimental form, and |
| -- should be ignored by all code generating back ends. ??? |
| |
| -- N_SCIL_Dispatch_Table_Tag_Init |
| -- Sloc references a node for a tag initialization |
| -- SCIL_Entity (Node4-Sem) |
| |
| -- N_SCIL_Dispatching_Call |
| -- Sloc references the node of a dispatching call |
| -- SCIL_Target_Prim (Node2-Sem) |

| |
| -- This node generates the appropriate Subprogram_Info value for a |
| -- given procedure. See Ada.Exceptions for further details |
| |
| -- Sprint syntax: subprog'subprogram_info |
| |
| -- N_Subprogram_Info |
| -- Sloc points to the entity for the procedure |
| -- Identifier (Node1) identifier referencing the procedure |
| -- Etype (Node5-Sem) type (always set to Ada.Exceptions.Code_Loc |
| |
| -- Note: in the case where a debug source file is generated, the Sloc |
| -- for this node points to the quote in the Sprint file output. |

| -- Unchecked Expression -- |
| -------------------------- |
| |
| -- An unchecked expression is one that must be analyzed and resolved |
| -- with all checks off, regardless of the current setting of scope |
| -- suppress flags. |
| |
| -- Sprint syntax: `(expression) |
| |
| -- Note: this node is always removed from the tree (and replaced by |
| -- its constituent expression) on completion of analysis, so it only |
| -- appears in intermediate trees, and will never be seen by Gigi. |
| |
| -- N_Unchecked_Expression |
| -- Sloc is a copy of the Sloc of the expression |
| -- Expression (Node3) |
| -- plus fields for expression |
| |
| -- Note: in the case where a debug source file is generated, the Sloc |
| -- for this node points to the back quote in the Sprint file output. |
| |
| ------------------------------- |
| -- Unchecked Type Conversion -- |
| ------------------------------- |
| |
| -- An unchecked type conversion node represents the semantic action |
| -- corresponding to a call to an instantiation of Unchecked_Conversion. |
| -- It is generated as a result of actual use of Unchecked_Conversion |
| -- and also the expander generates unchecked type conversion nodes |
| -- directly for expansion of complex semantic actions. |
| |
| -- Note: an unchecked type conversion is a variable as far as the |
| -- semantics are concerned, which is convenient for the expander. |
| -- This does not change what Ada source programs are legal, since |
| -- clearly a function call to an instantiation of Unchecked_Conversion |
| -- is not a variable in any case. |
| |
| -- Sprint syntax: subtype-mark!(expression) |
| |
| -- N_Unchecked_Type_Conversion |
| -- Sloc points to related node in source |
| -- Subtype_Mark (Node4) |
| -- Expression (Node3) |
| -- Kill_Range_Check (Flag11-Sem) |
| -- No_Truncation (Flag17-Sem) |
| -- plus fields for expression |
| |
| -- Note: in the case where a debug source file is generated, the Sloc |
| -- for this node points to the exclamation in the Sprint file output. |
| |
| ----------------------------------- |
| -- Validate_Unchecked_Conversion -- |
| ----------------------------------- |
| |
| -- The front end does most of the validation of unchecked conversion, |
| -- including checking sizes (this is done after the back end is called |
| -- to take advantage of back-annotation of calculated sizes). |
| |
| -- The front end also deals with specific cases that are not allowed |
| -- e.g. involving unconstrained array types. |
| |
| -- For the case of the standard gigi backend, this means that all |
| -- checks are done in the front-end. |
| |
| -- However, in the case of specialized back-ends, notably the JVM |
| -- backend for JGNAT, additional requirements and restrictions apply |
| -- to unchecked conversion, and these are most conveniently performed |
| -- in the specialized back-end. |
| |
| -- To accommodate this requirement, for such back ends, the following |
| -- special node is generated recording an unchecked conversion that |
| -- needs to be validated. The back end should post an appropriate |
| -- error message if the unchecked conversion is invalid or warrants |
| -- a special warning message. |
| |
| -- Source_Type and Target_Type point to the entities for the two |
| -- types involved in the unchecked conversion instantiation that |
| -- is to be validated. |
| |
| -- Sprint syntax: validate Unchecked_Conversion (source, target); |
| |
| -- N_Validate_Unchecked_Conversion |
| -- Sloc points to instantiation (location for warning message) |
| -- Source_Type (Node1-Sem) |
| -- Target_Type (Node2-Sem) |
| |
| -- Note: in the case where a debug source file is generated, the Sloc |
| -- for this node points to the VALIDATE keyword in the file output. |
