package Einfo is
|
|
|
|
-- This package defines the annotations to the abstract syntax tree that
|
|
-- are needed to support semantic processing of an Ada compilation.
|
|
|
|
-- These annotations are for the most part attributes of declared entities,
|
|
-- and they correspond to conventional symbol table information. Other
|
|
-- attributes include sets of meanings for overloaded names, possible
|
|
-- types for overloaded expressions, flags to indicate deferred constants,
|
|
-- incomplete types, etc. These attributes are stored in available fields
|
|
-- in tree nodes (i.e. fields not used by the parser, as defined by the
|
|
-- Sinfo package specification), and accessed by means of a set of
|
|
-- subprograms which define an abstract interface.
|
|
|
|
-- There are two kinds of semantic information
|
|
|
|
-- First, the tree nodes with the following Nkind values:
|
|
|
|
-- N_Defining_Identifier
|
|
-- N_Defining_Character_Literal
|
|
-- N_Defining_Operator_Symbol
|
|
|
|
-- are called Entities, and constitute the information that would often
|
|
-- be stored separately in a symbol table. These nodes are all extended
|
|
-- to provide extra space, and contain fields which depend on the entity
|
|
-- kind, as defined by the contents of the Ekind field. The use of the
|
|
-- Ekind field, and the associated fields in the entity, are defined
|
|
-- in this package, as are the access functions to these fields.
|
|
|
|
-- Second, in some cases semantic information is stored directly in other
|
|
-- kinds of nodes, e.g. the Etype field, used to indicate the type of an
|
|
-- expression. The access functions to these fields are defined in the
|
|
-- Sinfo package, but their full documentation is to be found in
|
|
-- the Einfo package specification.
|
|
|
|
-- Declaration processing places information in the nodes of their defining
|
|
-- identifiers. Name resolution places in all other occurrences of an
|
|
-- identifier a pointer to the corresponding defining occurrence.

|
-- The XEINFO Utility Program --
|
|
--------------------------------
|
|
|
|
-- XEINFO is a utility program which automatically produces a C header file,
|
|
-- a-xeinfo.h from the spec and body of package Einfo. It reads the input
|
|
-- files einfo.ads and einfo.adb and produces the output file a-xeinfo.h.
|
|
|
|
-- In order for this utility program to operate correctly, the form of the
|
|
-- einfo.ads and einfo.adb files must meet certain requirements and be laid
|
|
-- out in a specific manner.
|
|
|
|
-- The general form of einfo.ads is as follows:
|
|
|
|
-- type declaration for type Entity_Kind
|
|
-- subtype declarations declaring subranges of Entity_Kind
|
|
-- subtype declarations declaring synonyms for some standard types
|
|
-- function specs for attributes
|
|
-- procedure specs
|
|
-- pragma Inline declarations
|
|
|
|
-- This order must be observed. There are no restrictions on the procedures,
|
|
-- since the C header file only includes functions (Gigi is not allowed to
|
|
-- modify the generated tree). However, functions are required to have headers
|
|
-- that fit on a single line.
|
|
|
|
-- XEINFO reads and processes the function specs and the pragma Inlines. For
|
|
-- functions that are declared as inlined, XEINFO reads the corresponding body
|
|
-- from xeinfo.adb, and processes it into C code. This results in some strict
|
|
-- restrictions on which functions can be inlined:
|
|
|
|
-- The function spec must be on a single line
|
|
|
|
-- There can only be a single statement, contained on a single line,
|
|
-- not counting any pragma Assert statements.
|
|
|
|
-- This single statement must either by a function call with simple,
|
|
-- single token arguments, or it must be a membership test of the form
|
|
-- a in b, where a and b are single tokens.
|
|
|
|
-- For functions that are not inlined, there is no restriction on the body,
|
|
-- and XEINFO generates a direct reference in the C header file which allows
|
|
-- the C code in Gigi to directly call the corresponding Ada body.

|
|
-- Handling of Type'Size Values --
|
|
----------------------------------
|
|
|
|
-- The Ada 95 RM contains some rather peculiar (to us!) rules on the value
|
|
-- of type'Size (see RM 13.3(55)). We have found that attempting to use
|
|
-- these RM Size values generally, and in particular for determining the
|
|
-- default size of objects, creates chaos, and major incompatibilies in
|
|
-- existing code.
|
|
|
|
-- We proceed as follows, for discrete and fixed-point subtypes, we have
|
|
-- two separate sizes for each subtype:
|
|
|
|
-- The Object_Size, which is used for determining the default size of
|
|
-- objects and components. This size value can be referred to using the
|
|
-- Object_Size attribute. The phrase "is used" here means that it is
|
|
-- the basis of the determination of the size. The backend is free to
|
|
-- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone
|
|
-- character might be stored in 32 bits on a machine with no efficient
|
|
-- byte access instructions such as the Alpha.
|
|
|
|
-- The default rules for the value of Object_Size for fixed-point and
|
|
-- discrete types are as follows:
|
|
|
|
-- The Object_Size for base subtypes reflect the natural hardware
|
|
-- size in bits (see Ttypes and Cstand for integer types). For
|
|
-- enumeration and fixed-point base subtypes have 8. 16. 32 or 64
|
|
-- bits for this size, depending on the range of values to be stored.
|
|
|
|
-- The Object_Size of a subtype is the same as the Object_Size of
|
|
-- the subtype from which it is obtained.
|
|
|
|
-- The Object_Size of a derived base type is copied from the parent
|
|
-- base type, and the Object_Size of a derived first subtype is copied
|
|
-- from the parent first subtype.
|
|
|
|
-- The Value_Size which is the number of bits required to store a value
|
|
-- of the type. This size can be referred to using the Value_Size
|
|
-- attribute. This value is used to determine how tightly to pack
|
|
-- records or arrays with components of this type, and also affects
|
|
-- the semantics of unchecked conversion (unchecked conversions where
|
|
-- the Value_Size values differ generate a warning, and are potentially
|
|
-- target dependent).
|
|
|
|
-- The default rule for the value of Value_Size are as follows:
|
|
|
|
-- The Value_Size for a base subtype is the minimum number of bits
|
|
-- required to store all values of the type (including the sign bit
|
|
-- only if negative values are possible).
|
|
|
|
-- If a subtype statically matches the first subtype, then it has
|
|
-- by default the same Value_Size as the first subtype. This is a
|
|
-- consequence of RM 13.1(14) ("if two subtypes statically match,
|
|
-- then their subtype-specific aspects are the same".)
|
|
|
|
-- All other subtypes have a Value_Size corresponding to the minimum
|
|
-- number of bits required to store all values of the subtype. For
|
|
-- dynamic bounds, it is assumed that the value can range down or up
|
|
-- to the corresponding bound of the ancestor
|
|
|
|
-- The RM defined attribute Size corresponds to the Value_Size attribute.
|
|
|
|
-- The Size attribute may be defined for a first-named subtype. This sets
|
|
-- the Value_Size of the first-named subtype to the given value, and the
|
|
-- Object_Size of this first-named subtype to the given value padded up
|
|
-- to an appropriate boundary. It is a consequence of the default rules
|
|
-- above that this Object_Size will apply to all further subtypes. On the
|
|
-- otyher hand, Value_Size is affected only for the first subtype, any
|
|
-- dynamic subtypes obtained from it directly, and any statically matching
|
|
-- subtypes. The Value_Size of any other static subtypes is not affected.
|
|
|
|
-- Value_Size and Object_Size may be explicitly set for any subtype using
|
|
-- an attribute definition clause. Note that the use of these attributes
|
|
-- can cause the RM 13.1(14) rule to be violated. If two access types
|
|
-- reference aliased objects whose subtypes have differing Object_Size
|
|
-- values as a result of explicit attribute definition clauses, then it
|
|
-- is erroneous to convert from one access subtype to the other.
|
|
|
|
-- At the implementation level, Esize stores the Object_Size and the
|
|
-- RM_Size field stores the Value_Size (and hence the value of the
|
|
-- Size attribute, which, as noted above, is equivalent to Value_Size).
|
|
|
|
-- To get a feel for the difference, consider the following examples (note
|
|
-- that in each case the base is short_short_integer with a size of 8):
|
|
|
|
-- Object_Size Value_Size
|
|
|
|
-- type x1 is range 0..5; 8 3
|
|
|
|
-- type x2 is range 0..5;
|
|
-- for x2'size use 12; 12 12
|
|
|
|
-- subtype x3 is x2 range 0 .. 3; 12 2
|
|
|
|
-- subtype x4 is x2'base range 0 .. 10; 8 4
|
|
|
|
-- subtype x5 is x2 range 0 .. dynamic; 12 (7)
|
|
|
|
-- subtype x6 is x2'base range 0 .. dynamic; 8 (7)
|
|
|
|
-- Note: the entries marked (7) are not actually specified by the Ada 95 RM,
|
|
-- but it seems in the spirit of the RM rules to allocate the minimum number
|
|
-- of bits known to be large enough to hold the given range of values.
|
|
|
|
-- So far, so good, but GNAT has to obey the RM rules, so the question is
|
|
-- under what conditions must the RM Size be used. The following is a list
|
|
-- of the occasions on which the RM Size must be used:
|
|
|
|
-- Component size for packed arrays or records
|
|
-- Value of the attribute Size for a type
|
|
-- Warning about sizes not matching for unchecked conversion
|
|
|
|
-- The RM_Size field keeps track of the RM Size as needed in these
|
|
-- three situations.
|
|
|
|
-- For types other than discrete and fixed-point types, the Object_Size
|
|
-- and Value_Size are the same (and equivalent to the RM attribute Size).
|
|
-- Only Size may be specified for such types.

|
|
-- Entity Attributes --
|
|
-----------------------
|
|
|
|
-- This section contains a complete list of the attributes that are defined
|
|
-- on entities. Some attributes apply to all entities, others only to certain
|
|
-- kinds of entities. In the latter case the attribute should only be set or
|
|
-- accessed if the Ekind field indicates an appropriate entity.
|
|
|
|
-- There are two kinds of attributes that apply to entities, stored and
|
|
-- synthesized. Stored attributes correspond to a field or flag in the entity
|
|
-- itself. Such attributes are identified in the table below by giving the
|
|
-- field or flag in the attribute that is used to hold the attribute value.
|
|
-- Synthesized attributes are not stored directly, but are rather computed as
|
|
-- needed from other attributes, or from information in the tree. These are
|
|
-- marked "synthesized" in the table below. The stored attributes have both
|
|
-- access functions and set procedures to set the corresponding values, while
|
|
-- synthesized attributes have only access functions.
|
|
|
|
-- Note: in the case of Node, Uint, or Elist fields, there are cases where
|
|
-- the same physical field is used for different purposes in different
|
|
-- entities, so these access functions should only be referenced for the
|
|
-- class of entities in which they are defined as being present. Flags are
|
|
-- not overlapped in this way, but nevertheless as a matter of style and
|
|
-- abstraction (which may or may not be checked by assertions in the body),
|
|
-- this restriction should be observed for flag fields as well.
|
|
|
|
-- Note: certain of the attributes on types apply only to base types, and
|
|
-- are so noted by the notation [base type only]. These are cases where the
|
|
-- attribute of any subtype is the same as the attribute of the base type.
|
|
-- The attribute can be referenced on a subtype (and automatically retrieves
|
|
-- the value from the base type). However, it is an error to try to set the
|
|
-- attribute on other than the base type, and if assertions are enabled,
|
|
-- an attempt to set the attribute on a subtype will raise an assert error.
|
|
|
|
-- Other attributes are noted as applying the implementation base type only.
|
|
-- These are representation attributes which must always apply to a full
|
|
-- non-private type, and where the attributes are always on the full type.
|
|
-- The attribute can be referenced on a subtype (and automatically retries
|
|
-- the value from the implementation base type). However, it is an error
|
|
-- to try to set the attribute on other than the implementation base type,
|
|
-- and if assertions are enabled, an attempt to set the attribute on a
|
|
-- subtype will raise an assert error.
|
|
|
|
-- Accept_Address (Elist21)
|
|
-- Present in entries. If an accept has a statement sequence, then an
|
|
-- address variable is created, which is used to hold the address of the
|
|
-- parameters, as passed by the runtime. Accept_Address holds an element
|
|
-- list which represents a stack of entities for these address variables.
|
|
-- The current entry is the top of the stack, which is the last element
|
|
-- on the list. A stack is required to handle the case of nested select
|
|
-- statements referencing the same entry.
|
|
|
|
-- Actual_Subtype (Node17)
|
|
-- Present in variables, constants, and formal parameters. This is the
|
|
-- subtype imposed by the value of the object, as opposed to its nominal
|
|
-- subtype, which is imposed by the declaration. The actual subtype
|
|
-- differs from the nominal one when the latter is indefinite (as in the
|
|
-- case of an unconstrained formal parameter, or a variable declared
|
|
-- with an unconstrained type and an initial value). The nominal subtype
|
|
-- is the Etype entry for the entity. The Actual_Subtype field is set
|
|
-- only if the actual subtype differs from the nominal subtype. If the
|
|
-- actual and nominal subtypes are the same, then the Actual_Subtype
|
|
-- field is Empty, and Etype indicates both types.
|
|
--
|
|
-- For objects, the Actual_Subtype is set only if this is a discriminated
|
|
-- type. For arrays, the bounds of the expression are obtained and the
|
|
-- Etype of the object is directly the constrained subtype. This is
|
|
-- rather irregular, and the semantic checks that depend on the nominal
|
|
-- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
|
|
|
|
-- Access_Disp_Table (Node16) [implementation base type only]
|
|
-- Present in record type entities. For a tagged type, points to the
|
|
-- dispatch table associated with the tagged type. For a non-tagged
|
|
-- record, contains Empty.
|
|
|
|
-- Address_Clause (synthesized)
|
|
-- Applies to entries, objects and subprograms. Set if an address clause
|
|
-- is present which references the object or subprogram and points to
|
|
-- the N_Attribute_Definition_Clause node. Empty if no Address clause.
|
|
-- The expression in the address clause is always a constant that is
|
|
-- defined before the entity to which the address clause applies.
|
|
-- Note: Gigi references this field in E_Task_Type entities???
|
|
|
|
-- Address_Taken (Flag104)
|
|
-- Present in all entities. Set if the Address or Unrestricted_Access
|
|
-- attribute is applied directly to the entity, i.e. the entity is the
|
|
-- entity of the prefix of the attribute reference. Used by Gigi to
|
|
-- make sure that the address can be meaningfully taken.
|
|
|
|
-- Alias (Node18)
|
|
-- Present in overloaded entities (literals, subprograms, entries).
|
|
-- Points to parent subprogram of a derived subprogram. Also used for
|
|
-- a subprogram renaming, where it points to the renamed subprogram.
|
|
-- Always empty for entries.
|
|
|
|
-- Alignment (Uint14)
|
|
-- Present in all entities for types and objects. This indicates the
|
|
-- desired alignment for a type, or the actual alignment for an object.
|
|
-- A value of zero (Uint_0) indicates that the alignment is not yet set.
|
|
-- The alignment can be set by an explicit alignment clause, or set by
|
|
-- the front-end in package Layout, or set by the back-end.
|
|
|
|
-- Alignment_Clause (synthesized)
|
|
-- Appllies to all entities for types and objects. If an alignment
|
|
-- attribute definition clause is present for the entity, then this
|
|
-- function returns the N_Attribute_Definition clause that specifies the
|
|
-- alignment. If no alignment clause applies to the type, then the call
|
|
-- to this function returns Empty. Note that the call can return a
|
|
-- non-Empty value even if Has_Alignment_Clause is not set (happens with
|
|
-- subtype and derived type declarations). Note also that a record
|
|
-- definition clause with an (obsolescent) mod clause is converted
|
|
-- into an attribute definition clause for this purpose.
|
|
|
|
-- Ancestor_Subtype (synthesized)
|
|
-- Applies to all type and subtype entities. If the argument is a
|
|
-- subtype then it returns the subtype or type from which the subtype
|
|
-- was obtained, otherwise it returns Empty.
|
|
|
|
-- Associated_Formal_Package (Node12)
|
|
-- Present in packages that are the actuals of formal_packages. Points
|
|
-- to the entity in the declaration for the formal package.
|
|
|
|
-- Associated_Node_For_Itype (Node8)
|
|
-- Present in all type and subtype entities. Set non-Empty only for
|
|
-- Itypes. Set to point to the associated node for the Itype, i.e.
|
|
-- the node whose elaboration generated the Itype. This is used for
|
|
-- copying trees, to determine whether or not to copy an Itype.
|
|
|
|
-- Associated_Storage_Pool (Node22) [root type only]
|
|
-- Present in simple and general access type entities. References the
|
|
-- storage pool to be used for the corresponding collection. A value of
|
|
-- Empty means that the default pool is to be used. This is present
|
|
-- only in the root type, since derived types must have the same pool
|
|
-- as the parent type.
|
|
|
|
-- Associated_Final_Chain (Node23)
|
|
-- Present in simple and general access type entities. References the
|
|
-- List_Controller object that holds the finalization chain on which
|
|
-- are attached dynamically allocated objects referenced by the access
|
|
-- type. Empty when the access type cannot reference a controlled object.
|
|
|
|
-- Barrier_Function (Node12)
|
|
-- Present in protected entries and entry families. This is the
|
|
-- subprogram declaration for the body of the function that returns
|
|
-- the value of the entry barrier.
|
|
|
|
-- Base_Type (synthesized)
|
|
-- Applies to all type entities. Returns the base type of a type or
|
|
-- subtype. The base type of a type is the type itself. The base type
|
|
-- of a subtype is the type that it constrains (which is always a type
|
|
-- entity, not some other subtype). Note that in the case of a subtype
|
|
-- of a private type, it is possible for the base type attribute to
|
|
-- return a private type, even if the subtype to which it applies is
|
|
-- non-private. See also Implementation_Base_Type. Note: it is allowed
|
|
-- to apply Base_Type to other than a type, in which case it simply
|
|
-- returns the entity unchanged.
|
|
|
|
-- Block_Node (Node11)
|
|
-- Present in block entities. Points to the identifier in the
|
|
-- Block_Statement itself. Used when retrieving the block construct
|
|
-- for finalization purposes, The block entity has an implicit label
|
|
-- declaration in the enclosing declarative part, and has otherwise
|
|
-- no direct connection in the tree with the block statement. The
|
|
-- link is to the identifier (which is an occurence of the entity)
|
|
-- and not to the block_statement itself, because the statement may
|
|
-- be rewritten, e.g. in the process of removing dead code.
|
|
|
|
-- Body_Entity (Node19)
|
|
-- Present in package and generic package entities, points to the
|
|
-- corresponding package body entity if one is present.
|
|
|
|
-- C_Pass_By_Copy (Flag125) [implementation base type only]
|
|
-- Present in record types. Set if a pragma Convention for the record
|
|
-- type specifies convention C_Pass_By_Copy. This convention name is
|
|
-- treated as identical in all respects to convention C, except that
|
|
-- if it is specified for a record type, then the C_Pass_By_Copy flag
|
|
-- is set, and if a foreign convention subprogram has a formal of the
|
|
-- corresponding type, then the parameter passing mechanism will be
|
|
-- set to By_Copy (unless specifically overridden by an Import or
|
|
-- Export pragma).
|
|
|
|
-- Chars (Name1)
|
|
-- Present in all entities. This field contains an entry into the names
|
|
-- table that has the character string of the identifier, character
|
|
-- literal or operator symbol. See Namet for further details. Note that
|
|
-- throughout the processing of the front end, this name is the simple
|
|
-- unqualified name. However, just before gigi is called, a call is made
|
|
-- to Qualify_All_Entity_Names. This causes entity names to be qualified
|
|
-- using the encoding described in exp_dbug.ads, and from that point on
|
|
-- (including post gigi steps such as cross-reference generation), the
|
|
-- entities will contain the encoded qualified names.
|
|
|
|
-- Class_Wide_Type (Node9)
|
|
-- Present in all type entities. For a tagged type or subtype, returns
|
|
-- the corresponding implicitly declared class-wide type. Set to Empty
|
|
-- for non-tagged types.
|
|
|
|
-- Cloned_Subtype (Node16)
|
|
-- Present in E_Record_Subtype and E_Class_Wide_Subtype entities.
|
|
-- Each such entity can either have a Discriminant_Constraint, in
|
|
-- which case it represents a distinct type from the base type (and
|
|
-- will have a list of components and discrimants in the list headed by
|
|
-- First_Entity) or else no such constraint, in which case it will be a
|
|
-- copy of the base type.
|
|
--
|
|
-- o Each element of the list in First_Entity is copied from the base
|
|
-- type; in that case, this field is Empty.
|
|
--
|
|
-- o The list in First_Entity is shared with the base type; in that
|
|
-- case, this field points to that entity.
|
|
--
|
|
-- A record or classwide subtype may also be a copy of some other
|
|
-- subtype and share the entities in the First_Entity with that subtype.
|
|
-- In that case, this field points to that subtype.
|
|
--
|
|
-- For E_Class_Wide_Subtype, the presence of Equivalent_Type overrides
|
|
-- this field. Note that this field ONLY appears in subtype entries, not
|
|
-- in type entries, it is not present, and it is an error to reference
|
|
-- Cloned_Subtype in an E_Record_Type or E_Class_Wide_Type entity.
|
|
|
|
-- Comes_From_Source
|
|
-- This flag appears on all nodes, including entities, and indicates
|
|
-- that the node was created by the scanner or parser from the original
|
|
-- source. Thus for entities, it indicates that the entity is defined
|
|
-- in the original source program.
|
|
|
|
-- Component_Alignment (special field) [base type only]
|
|
-- Present in array and record entities. Contains a value of type
|
|
-- Component_Alignment_Kind indicating the alignment of components.
|
|
-- Set to Calign_Default normally, but can be overridden by use of
|
|
-- the Component_Alignment pragma. Note: this field is currently
|
|
-- stored in a non-standard way, see body for details.
|
|
|
|
-- Component_Bit_Offset (Uint11)
|
|
-- Present in record components (E_Component, E_Discriminant) if a
|
|
-- component clause applies to the component. First bit position of
|
|
-- given component, computed from the first bit and position values
|
|
-- given in the component clause. A value of No_Uint means that the
|
|
-- value is not yet known. The value can be set by the appearence of
|
|
-- an explicit component clause in a record representation clause,
|
|
-- or it can be set by the front-end in package Layout, or it can be
|
|
-- set by the backend. By the time backend processing is completed,
|
|
-- this field is always set. A negative value is used to represent
|
|
-- a value which is not known at compile time, and must be computed
|
|
-- at run-time (this happens if fields of a record have variable
|
|
-- lengths). See package Layout for details of these values.
|
|
--
|
|
-- Note: this field is obsolescent, to be eventually replaced entirely
|
|
-- by Normalized_First_Bit and Normalized_Position, but for the moment,
|
|
-- gigi is still using (and back annotating) this field, and gigi does
|
|
-- not know about the new fields. For the front end layout case, the
|
|
-- Component_Bit_Offset field is only set if it is static, and otherwise
|
|
-- the new Normalized_First_Bit and Normalized_Position fields are used.
|
|
|
|
-- Component_Clause (Node13)
|
|
-- Present in record components and discriminants. If a record
|
|
-- representation clause is present for the corresponding record
|
|
-- type a that specifies a position for the component, then the
|
|
-- Component_Clause field of the E_Component entity points to the
|
|
-- N_Component_Claue node. Set to Empty if no record representation
|
|
-- clause was present, or if there was no specification for this
|
|
-- component.
|
|
|
|
-- Component_Size (Uint22) [implementation base type only]
|
|
-- Present in array types. It contains the component size value for
|
|
-- the array. A value of zero means that the value is not yet set.
|
|
-- The value can be set by the use of a component size clause, or
|
|
-- by the front end in package Layout, or by the backend. A negative
|
|
-- value is used to represent a value which is not known at compile
|
|
-- time, and must be computed at run-time (this happens if the type
|
|
-- of the component has a variable length size). See package Layout
|
|
-- for details of these values.
|
|
|
|
-- Component_Type (Node20) [implementation base type only]
|
|
-- Present in array types and string types. References component type.
|
|
|
|
-- Constant_Value (synthesized)
|
|
-- Applies to constants, named integers, and named reals. Obtains
|
|
-- the initialization expression for the entity. Will return Empty for
|
|
-- for a deferred constant whose full view is not available or in some
|
|
-- other cases of internal entities, which cannot be treated as
|
|
-- constants from the point of view of constant folding.
|
|
|
|
-- Corresponding_Concurrent_Type (Node18)
|
|
-- Present in record types that are constructed by the expander to
|
|
-- represent task and protected types (Is_Concurrent_Record_Type flag
|
|
-- set True). Points to the entity for the corresponding task type or
|
|
-- protected type.
|
|
|
|
-- Corresponding_Discriminant (Node19)
|
|
-- Present in discriminants of a derived type, when the discriminant is
|
|
-- used to constrain a discriminant of the parent type. Points to the
|
|
-- corresponding discriminant in the parent type. Otherwise it is Empty.
|
|
|
|
-- Corresponding_Equality (Node13)
|
|
-- Present in function entities for implicit inequality operators.
|
|
-- Denotes the explicit or derived equality operation that creates
|
|
-- the implicit inequality. Note that this field is not present in
|
|
-- other function entities, only in implicit inequality routines,
|
|
-- where Comes_From_Source is always False.
|
|
|
|
-- Corresponding_Record_Type (Node18)
|
|
-- Present in protected and task types and subtypes. References the
|
|
-- entity for the corresponding record type constructed by the expander
|
|
-- (see Exp_Ch9). This type is used to represent values of the task type.
|
|
|
|
-- Corresponding_Remote_Type (Node22)
|
|
-- Present in record types that describe the fat pointer structure for
|
|
-- Remote_Access_To_Subrogram types. References the original access type.
|
|
|
|
-- CR_Discriminant (Node23)
|
|
-- Present in discriminants of concurrent types. Denotes the homologous
|
|
-- discriminant of the corresponding record type. The CR_Discriminant is
|
|
-- created at the same time as the discriminal, and used to replace
|
|
-- occurrences of the discriminant within the type declaration.
|
|
|
|
-- Debug_Info_Off (Flag166)
|
|
-- Present in all entities. Set if a pragma Suppress_Debug_Info applies
|
|
-- to the entity, or if internal processing in the compiler determines
|
|
-- that suppression of debug information is desirable.
|
|
|
|
-- Debug_Renaming_Link (Node13)
|
|
-- Used to link the enumeration literal of a debug renaming declaration
|
|
-- to the renamed entity. See Exp_Dbug.Debug_Renaming_Declaration for
|
|
-- details of the use of this field.
|
|
|
|
-- Declaration_Node (synthesized)
|
|
-- Applies to all entities. Returns the tree node for the declaration
|
|
-- that declared the entity. Normally this is just the Parent of the
|
|
-- entity. One exception arises with child units, where the parent of
|
|
-- the entity is a selected component or a defining program unit name.
|
|
-- Another exception is that if the entity is an incomplete type that
|
|
-- has been completed, then we obtain the declaration node denoted by
|
|
-- the full type, i.e. the full type declaration node.
|
|
|
|
-- Default_Expr_Function (Node21)
|
|
-- Present in parameters. It holds the entity of the parameterless
|
|
-- function that is built to evaluate the default expression if it is
|
|
-- more complex than a simple identifier or literal. For the latter
|
|
-- simple cases or if there is no default value, this field is Empty.
|
|
|
|
-- Default_Expressions_Processed (Flag108)
|
|
-- A flag in subprograms (functions, operators, procedures) and in
|
|
-- entries and entry families used to indicate that default expressions
|
|
-- have been processed and to avoid multiple calls to process the
|
|
-- default expressions (see Freeze.Process_Default_Expressions), which
|
|
-- would not only waste time, but also generate false error messages.
|
|
|
|
-- Default_Value (Node20)
|
|
-- Present in formal parameters. Points to the node representing the
|
|
-- expression for the default value for the parameter. Empty if the
|
|
-- parameter has no default value (which is always the case for OUT
|
|
-- and IN OUT parameters in the absence of errors).
|
|
|
|
-- Delay_Cleanups (Flag114)
|
|
-- Present in entities that have finalization lists (subprograms
|
|
-- blocks, and tasks). Set if there are pending generic body
|
|
-- instantiations for the corresponding entity. If this flag is
|
|
-- set, then generation of cleanup actions for the corresponding
|
|
-- entity must be delayed, since the insertion of the generic body
|
|
-- may affect cleanup generation (see Inline for further details).
|
|
|
|
-- Delay_Subprogram_Descriptors (Flag50)
|
|
-- Present in entities for which exception subprogram descriptors
|
|
-- are generated (subprograms, package declarations and package
|
|
-- bodies). Present if there are pending generic body instantiations
|
|
-- for the corresponding entity. If this flag is set, then generation
|
|
-- of the subprogram descriptor for the corresponding enities must
|
|
-- be delayed, since the insertion of the generic body may add entries
|
|
-- to the list of handlers.
|
|
--
|
|
-- Note: for subprograms, Delay_Subprogram_Descriptors is set if and
|
|
-- only if Delay_Cleanups is set. But Delay_Cleanups can be set for a
|
|
-- a block (in which case Delay_Subprogram_Descriptors is set for the
|
|
-- containing subprogram). In addition Delay_Subprogram_Descriptors is
|
|
-- set for a library level package declaration or body which contains
|
|
-- delayed instantiations (in this case the descriptor refers to the
|
|
-- enclosing elaboration procedure).
|
|
|
|
-- Delta_Value (Ureal18)
|
|
-- Present in fixed and decimal types. Points to a universal real
|
|
-- that holds value of delta for the type, as given in the declaration
|
|
-- or as inherited by a subtype or derived type.
|
|
|
|
-- Dependent_Instances (Elist8)
|
|
-- Present in packages that are instances. Holds list of instances
|
|
-- of inner generics. Used to place freeze nodes for those instances
|
|
-- after that of the current one, i.e. after the corresponding generic
|
|
-- bodies.
|
|
|
|
-- Depends_On_Private (Flag14)
|
|
-- Present in all type entities. Set if the type is private or if it
|
|
-- depends on a private type.
|
|
|
|
-- Designated_Type (synthesized)
|
|
-- Applies to access types. Returns the designated type. Differs
|
|
-- from Directly_Designated_Type in that if the access type refers
|
|
-- to an incomplete type, and the full type is available, then this
|
|
-- full type is returned instead of the incomplete type.
|
|
|
|
-- Digits_Value (Uint17)
|
|
-- Present in floating point types and subtypes and decimal types and
|
|
-- subtypes. Contains the Digits value specified in the declaration.
|
|
|
|
-- Directly_Designated_Type (Node20)
|
|
-- Present in access types. This field points to the type that is
|
|
-- directly designated by the access type. In the case of an access
|
|
-- type to an incomplete type, this field references the incomplete
|
|
-- type. Note that in the semantic processing, what is useful in
|
|
-- nearly all cases is the full type designated by the access type.
|
|
-- The function Designated_Type obtains this full type in the case of
|
|
-- access to an incomplete type.
|
|
|
|
-- Discard_Names (Flag88)
|
|
-- Present in types and exception entities. Set if pragma Discard_Names
|
|
-- applies to the entity. It is also set for declarative regions and
|
|
-- package specs for which a Discard_Names pragma with zero arguments
|
|
-- has been encountered. The purpose of setting this flag is to be able
|
|
-- to set the Discard_Names attribute on enumeration types declared
|
|
-- after the pragma within the same declarative region.
|
|
|
|
-- Discriminal (Node17)
|
|
-- Present in discriminants (Discriminant formal: GNAT's first
|
|
-- coinage). The entity used as a formal parameter that corresponds
|
|
-- to a discriminant. See section "Use of Discriminants" for details.
|
|
|
|
-- Discriminal_Link (Node10)
|
|
-- Present in discriminals (which have an Ekind of E_In_Parameter,
|
|
-- or E_Constant), points back to corresponding discriminant.
|
|
|
|
-- Discriminant_Checking_Func (Node20)
|
|
-- Present in components. Points to the defining identifier of the
|
|
-- function built by the expander returns a Boolean indicating whether
|
|
-- the given record component exists for the current discriminant
|
|
-- values.
|
|
|
|
-- Discriminant_Constraint (Elist21)
|
|
-- Present in entities whose Has_Discriminants flag is set (concurrent
|
|
-- types, subtypes, record types and subtypes, private types and
|
|
-- subtypes, limited private types and subtypes and incomplete types).
|
|
-- It is an error to reference the Discriminant_Constraint field if
|
|
-- Has_Disciminants is False.
|
|
--
|
|
-- If the Is_Constrained flag is set, Discriminant_Constraint points
|
|
-- to an element list containing the discriminant constraints in the
|
|
-- same order in which the discriminants are declared.
|
|
--
|
|
-- If the Is_Constrained flag is not set but the discriminants of the
|
|
-- unconstrained type have default initial values then this field
|
|
-- points to an element list giving these default initial values in
|
|
-- the same order in which the discriminants are declared. Note that
|
|
-- in this case the entity cannot be a tagged record type, because
|
|
-- discriminants in this case cannot have defaults.
|
|
--
|
|
-- If the entity is a tagged record implicit type, then this field is
|
|
-- inherited from the first subtype (so that the itype is subtype
|
|
-- conformant with its first subtype, which is needed when the first
|
|
-- subtype overrides primitive operations inherited by the implicit
|
|
-- base type).
|
|
--
|
|
-- In all other cases Discriminant_Constraint contains the empty
|
|
-- Elist (ie it is initialized with a call to New_Elmt_List).
|
|
|
|
-- Discriminant_Default_Value (Node20)
|
|
-- Present in discriminants. Points to the node representing the
|
|
-- expression for the default value of the discriminant. Set to
|
|
-- Empty if the discriminant has no default value.
|
|
|
|
-- Discriminant_Number (Uint15)
|
|
-- Present in discriminants. Gives the ranking of a discriminant in
|
|
-- the list of discriminants of the type, i.e. a sequential integer
|
|
-- index starting at 1 and ranging up to Number_Discriminants.
|
|
|
|
-- DTC_Entity (Node16)
|
|
-- Present in function and procedure entities. Set to Empty unless
|
|
-- the subprogram is dispatching in which case it references the
|
|
-- Dispatch Table pointer Component. That is to say the component _tag
|
|
-- for regular Ada tagged types, for CPP_Class types and their
|
|
-- descendants this field points to the component entity in the record
|
|
-- that is the Vtable pointer for the Vtable containing the entry that
|
|
-- references the subprogram.
|
|
|
|
-- DT_Entry_Count (Uint15)
|
|
-- Present in E_Component entities. Only used for component marked
|
|
-- Is_Tag. Store the number of entries in the Vtable (or Dispatch Table)
|
|
|
|
-- DT_Position (Uint15)
|
|
-- Present in function and procedure entities which are dispatching
|
|
-- (should not be referenced without first checking that flag
|
|
-- Is_Dispatching_Operation is True). Contains the offset into
|
|
-- the Vtable for the entry that references the subprogram.
|
|
|
|
-- Ekind (Ekind)
|
|
-- Present in all entities. Contains a value of the enumeration type
|
|
-- Entity_Kind declared in a subsequent section in this spec.
|
|
|
|
-- Elaborate_All_Desirable (Flag146)
|
|
-- Present in package and subprogram entities, and in generic package
|
|
-- and subprogram entities. Set if internal analysis of a client that
|
|
-- with's this unit determines that Elaborate_All is desirable, i.e.
|
|
-- that there is a possibility that Program_Error may be raised if
|
|
-- Elaborate_All conditions cannot be met.
|
|
|
|
-- Elaboration_Entity (Node13)
|
|
-- Present in generic and non-generic package and subprogram
|
|
-- entities. This is a boolean entity associated with the unit that
|
|
-- is initiallly set to False, and is set True when the unit is
|
|
-- elaborated. This is used for two purposes. First, it is used to
|
|
-- implement required access before elaboration checks (the flag
|
|
-- must be true to call a subprogram at elaboration time). Second,
|
|
-- it is used to guard against repeated execution of the generated
|
|
-- elaboration code.
|
|
--
|
|
-- Note that we always allocate this flag, and set this field, but
|
|
-- we do not always actually use it. It is only used if it is needed
|
|
-- for access-before-elaboration use (see Elaboration_Entity_Required
|
|
-- flag) or if either the spec or the body has elaboration code. If
|
|
-- neither of these two conditions holds, then the entity is still
|
|
-- allocated (since we don't know early enough whether or not there
|
|
-- is elaboration code), but is simply not used for any purpose.
|
|
|
|
-- Elaboration_Entity_Required (Flag174)
|
|
-- Present in generics and non-generic package and subprogram
|
|
-- entities. Set only if Elaboration_Entity is non-Empty to indicate
|
|
-- that the boolean is required to be set even if there is no other
|
|
-- elaboration code. This occurs when the Elaboration_Entity flag
|
|
-- is used for required access-before-elaboration checking. If the
|
|
-- flag is only for preventing multiple execution of the elaboration
|
|
-- code, then if there is no other elaboration code, obviously there
|
|
-- is no need to set the flag.
|
|
|
|
-- Enclosing_Dynamic_Scope (synthesized)
|
|
-- Appliesa to all entities. Returns the closest dynamic scope in which
|
|
-- the entity is declared or Standard_Standard for library-level entities
|
|
|
|
-- Enclosing_Scope (Node18)
|
|
-- Present in labels. Denotes the innermost enclosing construct that
|
|
-- contains the label. Identical to the scope of the label, except for
|
|
-- labels declared in the body of an accept statement, in which case the
|
|
-- entry_name is the Enclosing_Scope. Used to validate goto's within
|
|
-- accept statements.
|
|
|
|
-- Entry_Accepted (Flag152)
|
|
-- Present in E_Entry and E_Entry_Family entities. Set if there is
|
|
-- at least one accept for this entry in the task body. Used to
|
|
-- generate warnings for missing accepts.
|
|
|
|
-- Entry_Bodies_Array (Node15)
|
|
-- Present in protected types for which Has_Entries is true.
|
|
-- This is the defining identifier for the array of entry body
|
|
-- action procedures and barrier functions used by the runtime to
|
|
-- execute the user code associated with each entry.
|
|
|
|
-- Entry_Cancel_Parameter (Node23)
|
|
-- Present in blocks. This only applies to a block statement for
|
|
-- which the Is_Asynchronous_Call_Block flag is set. It
|
|
-- contains the defining identifier of an object that must be
|
|
-- passed to the Cancel_Task_Entry_Call or Cancel_Protected_Entry_Call
|
|
-- call in the cleanup handler added to the block by
|
|
-- Exp_Ch7.Expand_Cleanup_Actions. This parameter is a Boolean
|
|
-- object for task entry calls and a Communications_Block object
|
|
-- in the case of protected entry calls. In both cases the objects
|
|
-- are declared in outer scopes to this block.
|
|
|
|
-- Entry_Component (Node11)
|
|
-- Present in formal parameters (in, in out and out parameters). Used
|
|
-- only for formals of entries. References the corresponding component
|
|
-- of the entry parameter record for the entry.
|
|
|
|
-- Entry_Formal (Node16)
|
|
-- Present in components of the record built to correspond to entry
|
|
-- parameters. This field points from the component to the formal. It
|
|
-- is the back pointer corresponding to Entry_Component.
|
|
|
|
-- Entry_Index_Constant (Node18)
|
|
-- Present in an entry index parameter. This is an identifier that
|
|
-- eventually becomes the name of a constant representing the index
|
|
-- of the entry family member whose entry body is being executed. Used
|
|
-- to expand references to the entry index specification identifier.
|
|
|
|
-- Entry_Index_Type (synthesized)
|
|
-- Applies to an entry family. Denotes Etype of the subtype indication
|
|
-- in the entry declaration. Used to resolve the index expression in an
|
|
-- accept statement for a member of the family, and in the prefix of
|
|
-- 'COUNT when it applies to a family member.
|
|
|
|
-- Entry_Parameters_Type (Node15)
|
|
-- Present in entries. Points to the access-to-record type that is
|
|
-- constructed by the expander to hold a reference to the parameter
|
|
-- values. This reference is manipulated (as an address) by the
|
|
-- tasking runtime. The designated record represents a packaging
|
|
-- up of the entry parameters (see Exp_Ch9.Expand_N_Entry_Declaration
|
|
-- for further details). Entry_Parameters_Type is Empty if the entry
|
|
-- has no parameters.
|
|
|
|
-- Enumeration_Pos (Uint11)
|
|
-- Present in enumeration literals. Contains the position number
|
|
-- corresponding to the value of the enumeration literal.
|
|
|
|
-- Enumeration_Rep (Uint12)
|
|
-- Present in enumeration literals. Contains the representation that
|
|
-- corresponds to the value of the enumeration literal. Note that
|
|
-- this is normally the same as Enumeration_Pos except in the presence
|
|
-- of representation clauses, where Pos will still represent the
|
|
-- position of the literal within the type and Rep will have be the
|
|
-- value given in the representation clause.
|
|
|
|
-- Enumeration_Rep_Expr (Node22)
|
|
-- Present in enumeration literals. Points to the expression in an
|
|
-- associated enumeration rep clause that provides the representation
|
|
-- value for this literal. Empty if no enumeration rep clause for this
|
|
-- literal (or if rep clause does not have an entry for this literal,
|
|
-- an error situation). This is also used to catch duplicate entries
|
|
-- for the same literal.
|
|
|
|
-- Enum_Pos_To_Rep (Node23)
|
|
-- Present in enumeration types (but not enumeration subtypes). Set to
|
|
-- Empty unless the enumeration type has a non-standard representation
|
|
-- (i.e. at least one literal has a representation value different from
|
|
-- its pos value). In this case, Enum_Pos_To_Rep is the entity for an
|
|
-- array constructed when the type is frozen that maps Pos values to
|
|
-- corresponding Rep values. The index type of this array is Natural,
|
|
-- and the component type is a suitable integer type that holds the
|
|
-- full range of representation values.
|
|
|
|
-- Equivalent_Type (Node18)
|
|
-- Present in class wide types and subtypes, access to protected
|
|
-- subprogram types, and in exception_types. For a classwide type, it
|
|
-- is always Empty. For a class wide subtype, it points to an entity
|
|
-- created by the expander which gives Gigi an easily understandable
|
|
-- equivalent of the class subtype with a known size (given by an
|
|
-- initial value). See Exp_Util.Expand_Class_Wide_Subtype for further
|
|
-- details. For E_exception_type, this points to the record containing
|
|
-- the data necessary to represent exceptions (for further details, see
|
|
-- System.Standard_Library. For access_to_protected subprograms, it
|
|
-- denotes a record that holds pointers to the operation and to the
|
|
-- protected object. For remote Access_To_Subprogram types, it denotes
|
|
-- the record that is the fat pointer representation of an RAST.
|
|
|
|
-- Esize (Uint12)
|
|
-- Present in all types and subtypes, an also for components, constants,
|
|
-- and variables. Contains the Object_Size of the type or of the object.
|
|
-- A value of zero indicates that the value is not yet known.
|
|
--
|
|
-- For the case of components where a component clause is present, the
|
|
-- value is the value from the component clause, which must be non-
|
|
-- negative (but may be zero, which is acceptable for the case of
|
|
-- a type with only one possible value). It is also possible for Esize
|
|
-- of a component to be set without a component clause present, which
|
|
-- means that the component size is specified, but not the position.
|
|
-- See also RM_Size and the section on "Handling of Type'Size Values".
|
|
-- During gigi processing, the value is back annotated for all zero
|
|
-- values, so that after the call to gigi, the value is properly set.
|
|
|
|
-- Etype (Node5)
|
|
-- Present in all entities. Represents the type of the entity, which
|
|
-- is itself another entity. For a type entity, points to the parent
|
|
-- type for a derived type, or if the type is not derived, points to
|
|
-- itself. For a subtype entity, Etype points to the base type.
|
|
|
|
-- Exception_Code (Uint22)
|
|
-- Present in exception entitites. Set to zero unless either an
|
|
-- Import_Exception or Export_Exception pragma applies to the
|
|
-- pragma and specifies a Code value. See description of these
|
|
-- pragmas for details. Note that this field is relevant only if
|
|
-- Is_VMS_Exception is set.
|
|
|
|
-- Extra_Formal (Node15)
|
|
-- Present in formal parameters in the non-generic case. Certain
|
|
-- parameters require extra implicit information to be passed
|
|
-- (e.g. the flag indicating if an unconstrained variant record
|
|
-- argument is constrained, and the accessibility level for
|
|
-- access parameters. See description of Extra_Constrained,
|
|
-- Extra_Accessibility fields for further details. Extra formal
|
|
-- parameters are constructed to represent these values, and
|
|
-- chained to the end of the list of formals using the
|
|
-- Extra_Formal field (i.e. the Extra_Formal field of the last
|
|
-- "real" formal points to the first extra formal, and the
|
|
-- Extra_Formal field of each extra formal points to the next
|
|
-- one, with Empty indicating the end of the list of extra
|
|
-- formals.
|
|
|
|
-- Extra_Accessibility (Node13)
|
|
-- Present in formal parameters in the non-generic case if
|
|
-- expansion is active. Normally Empty, but if a parameter is
|
|
-- one for which a dynamic accessibility check is required, then
|
|
-- an extra formal of type Natural is created (see description
|
|
-- of field Extra_Formal), and the Extra_Accessibility field of
|
|
-- the formal parameter points to the entity for this extra
|
|
-- formal. Also present in variables when compiling receiving
|
|
-- stubs. In this case, a non Empty value means that this
|
|
-- variable's accessibility depth has been transmitted by the
|
|
-- caller and must be retrieved through the entity designed by
|
|
-- this field instead of being computed.
|
|
|
|
-- Extra_Constrained (Node23)
|
|
-- Present in formal parameters in the non-generic case if
|
|
-- expansion is active. Normally Empty, but if a parameter is
|
|
-- one for which a dynamic indication of its constrained status
|
|
-- is required, then an extra formal of type Boolean is created
|
|
-- (see description of field Extra_Formal), and the
|
|
-- Extra_Constrained field of the formal parameter points to the
|
|
-- entity for this extra formal. Also present in variables when
|
|
-- compiling receiving stubs. In this case, a non empty value
|
|
-- means that this variable's constrained status has been
|
|
-- transmitted by the caller and must be retrieved through the
|
|
-- entity designed by this field instead of being computed.
|
|
|
|
-- Finalization_Chain_Entity (Node19)
|
|
-- Present in scopes which can have finalizable entities (blocks,
|
|
-- functions, procedures, tasks, entries). When this field is empty it
|
|
-- means that there are no finalization actions to perform on exit of the
|
|
-- scope. When this field contains 'Error', it means that no
|
|
-- finalization actions should happen at this level and the
|
|
-- finalization chain of a parent scope shall be used (??? this is
|
|
-- an improper use of 'Error' and should be changed). otherwise it
|
|
-- contains an entity of type Finalizable_Ptr that is the head of the
|
|
-- list of objects to finalize on exit. See "Finalization Management"
|
|
-- section in exp_ch7.adb for more details.
|
|
|
|
-- Finalize_Storage_Only (Flag158) [base type only]
|
|
-- Present in all types. Set on direct controlled types to which a
|
|
-- valid Finalize_Storage_Only pragma applies. This flag is also set on
|
|
-- composite types when they have at least one controlled component and
|
|
-- all their controlled components are Finalize_Storage_Only. It is also
|
|
-- inherited by type derivation except for direct controlled types where
|
|
-- the Finalize_Storage_Only pragma is required at each level of
|
|
-- derivation.
|
|
|
|
-- First_Component (synthesized)
|
|
-- Applies to record types. Returns the first component by following
|
|
-- the chain of declared entities for the record until a component
|
|
-- is found (one with an Ekind of E_Component). The discriminants are
|
|
-- skipped. If the record is null, then Empty is returned.
|
|
|
|
-- First_Discriminant (synthesized)
|
|
-- Applies to types with discriminants. The discriminants are the
|
|
-- first entities declared in the type, so normally this is equivalent
|
|
-- to First_Entity. The exception arises for tagged types, where the
|
|
-- tag itself is prepended to the front of the entity chain, so the
|
|
-- First_Discriminant function steps past the tag if it is present.
|
|
|
|
-- First_Girder_Discriminant (synthesized)
|
|
-- Applies to types with discriminants. For tagged types, and untagged
|
|
-- types which are root types or derived types but which do not rename
|
|
-- discriminants in their root type, this is the same as
|
|
-- First_Discriminant.
|
|
--
|
|
-- For derived non-tagged types that rename discriminants in the root
|
|
-- type this is the first of the discriminants that occurr in the
|
|
-- root type. To be precise, in this case girder discriminants are
|
|
-- entities attached to the entity chain of the derived type which
|
|
-- are a copy of the discriminants of the root type. Furthermore their
|
|
-- Is_Completely_Hidden flag is set.
|
|
--
|
|
-- For derived untagged types, girder discriminants are the real
|
|
-- discriminants from Gigi's standpoint, ie those that will be stored in
|
|
-- actual objects of the type.
|
|
|
|
-- First_Entity (Node17)
|
|
-- Present in all entities which act as scopes to which a list of
|
|
-- associated entities is attached (blocks, class subtypes and types,
|
|
-- entries, functions, loops, packages, procedures, protected objects,
|
|
-- record types and subtypes, private types, task types and subtypes).
|
|
-- Points to a list of associated entities using the Next_Entity field
|
|
-- as a chain pointer with Empty marking the end of the list.
|
|
|
|
-- First_Formal (synthesized)
|
|
-- Applies to subprograms and subprogram types, and also in entries
|
|
-- and entry families. Returns first formal of the subprogram or entry.
|
|
-- The formals are the first entities declared in a subprogram or in
|
|
-- a subprogram type (the designated type of an Access_To_Subprogram
|
|
-- definition) or in an entry.
|
|
|
|
-- First_Index (Node17)
|
|
-- Present in array types and subtypes and in string types and subtypes.
|
|
-- By introducing implicit subtypes for the index constraints, we have
|
|
-- the same structure for constrained and unconstrained arrays, subtype
|
|
-- marks and discrete ranges are both represented by a subtype. This
|
|
-- function returns the tree node corresponding to an occurrence of the
|
|
-- first index (NOT the entity for the type). Subsequent indexes are
|
|
-- obtained using Next_Index. Note that this field is present for the
|
|
-- case of string literal subtypes, but is always Empty.
|
|
|
|
-- First_Literal (Node17)
|
|
-- Present in all enumeration types, including character and boolean
|
|
-- types. This field points to the first enumeration literal entity
|
|
-- for the type (i.e. it is set to First (Literals (N)) where N is
|
|
-- the enumeration type definition node. A special case occurs with
|
|
-- standard character and wide character types, where this field is
|
|
-- Empty, since there are no enumeration literal lists in these cases.
|
|
|
|
-- First_Optional_Parameter (Node14)
|
|
-- Present in (non-generic) function and procedure entities. Set to a
|
|
-- non-null value only if a pragma Import_Function, Import_Procedure
|
|
-- or Import_Valued_Procedure specifies a First_Optional_Parameter
|
|
-- argument, in which case this field points to the parameter entity
|
|
-- corresponding to the specified parameter.
|
|
|
|
-- First_Private_Entity (Node16)
|
|
-- Present in all entities containing private parts (packages,
|
|
-- protected types and subtypes, task types and subtypes). The
|
|
-- entities on the entity chain are in order of declaration, so the
|
|
-- entries for private entities are at the end of the chain. This
|
|
-- field points to the first entity for the private part. It is
|
|
-- Empty if there are no entities declared in the private part or
|
|
-- if there is no private part.
|
|
|
|
-- First_Rep_Item (Node6)
|
|
-- Present in all entities. If non-empty, points to a linked list of
|
|
-- representation pragmas nodes and representation clause nodes that
|
|
-- apply to the entity, linked using Next_Rep_Item, with Empty marking
|
|
-- the end of the list. In the case of derived types and subtypes, the
|
|
-- new entity inherits the chain at the point of declaration. This
|
|
-- means that it is possible to have multiple instances of the same
|
|
-- kind of rep item on the chain, in which case it is the first one
|
|
-- that applies to the entity.
|
|
--
|
|
-- For most representation items, the representation information is
|
|
-- reflected in other fields and flags in the entity. For example if
|
|
-- a record representation clause is present, the component entities
|
|
-- reflect the specified information. However, there are some items
|
|
-- that are only reflected in the chain. These include:
|
|
--
|
|
-- Alignment attribute definition clause
|
|
-- Machine_Attribute pragma
|
|
-- Link_Alias pragma
|
|
-- Link-Section pragma
|
|
-- Weak_External pragma
|
|
--
|
|
-- If any of these items are present, then the flag Has_Gigi_Rep_Item
|
|
-- is set, indicating that Gigi should search the chain.
|
|
--
|
|
-- Other representation items are included in the chain so that error
|
|
-- messages can easily locate the relevant nodes for posting errors.
|
|
-- Note in particular that size clauses are present only for this
|
|
-- purpose, and should only be accessed if Has_Size_Clause is set.
|
|
|
|
-- First_Subtype (synthesized)
|
|
-- Applies to all types and subtypes. For types, yields the first
|
|
-- subtype of the type. For subtypes, yields the first subtype of
|
|
-- the base type of the subtype.
|
|
|
|
-- Freeze_Node (Node7)
|
|
-- Present in all entities. If there is an associated freeze node for
|
|
-- the entity, this field references this freeze node. If no freeze
|
|
-- node is associated with the entity, then this field is Empty. See
|
|
-- package Freeze for further details.
|
|
|
|
-- From_With_Type (Flag159)
|
|
-- Present in package and type entities. Indicates that the entity
|
|
-- appears in a With_Type clause in the context of some other unit,
|
|
-- either as the prefix (which must be a package), or as a type name.
|
|
-- The package can only be used to retrieve such a type, and the type
|
|
-- can be used only in component declarations and access definitions.
|
|
-- The With_Type clause is used to construct mutually recursive
|
|
-- types, i.e. record types (Java classes) that hold pointers to each
|
|
-- other. If such a type is an access type, it has no explicit freeze
|
|
-- node, so that the back-end does not attempt to elaborate it.
|
|
|
|
-- Full_View (Node11)
|
|
-- Present in all type and subtype entities and in deferred constants.
|
|
-- References the entity for the corresponding full type declaration.
|
|
-- For all types other than private and incomplete types, this field
|
|
-- always contains Empty. See also Underlying_Type.
|
|
|
|
-- Function_Returns_With_DSP (Flag169)
|
|
-- Present in all subprogram entities, and type entities for access
|
|
-- to subprogram values. Set True if the function (or referenced
|
|
-- function in the case of an access value) returns with using the
|
|
-- DSP (depressed stack pointer) approach. This can only be set
|
|
-- True if Targparm.Functions_Return_By_DSP_On_Target is True and
|
|
-- the function returns a value of a type whose size is not known
|
|
-- at compile time.
|
|
|
|
-- Generic_Renamings (Elist23)
|
|
-- Present in package and subprogram instances. Holds mapping that
|
|
-- associates generic parameters with the corresponding instances, in
|
|
-- those cases where the instance is an entity.
|
|
|
|
-- Girder_Constraint (Elist23)
|
|
-- Present in entities that can have discriminants (concurrent types
|
|
-- subtypes, record types and subtypes, private types and subtypes,
|
|
-- limited private types and subtypes and incomplete types). Points
|
|
-- to an element list containing the expressions for each of the
|
|
-- girder discriminants for the record (sub)type.
|
|
|
|
-- Handler_Records (List10)
|
|
-- Present in subprogram and package entities. Points to a list of
|
|
-- identifiers referencing the handler record entities for the
|
|
-- corresponding unit.
|
|
|
|
-- Has_Aliased_Components (Flag135) [implementation base type only]
|
|
-- Present in array type entities. Indicates that the component type
|
|
-- of the array is aliased.
|
|
|
|
-- Has_Alignment_Clause (Flag46)
|
|
-- Present in all type entities and objects. Indicates if an alignment
|
|
-- clause has been given for the entity. If set, then Alignment_Clause
|
|
-- returns the N_Attribute_Definition node for the alignment attribute
|
|
-- definition clause. Note that it is possible for this flag to be False
|
|
-- even when Alignment_Clause returns non_Empty (this happens in the case
|
|
-- of derived type declarations).
|
|
|
|
-- Has_All_Calls_Remote (Flag79)
|
|
-- Present in all library unit entities. Set true if the library unit
|
|
-- has an All_Calls_Remote pragma. Note that such entities must also
|
|
-- be RCI entities, so the flag Is_Remote_Call_Interface will always
|
|
-- be set if this flag is set.
|
|
|
|
-- Has_Atomic_Components (Flag86) [implementation base type only]
|
|
-- Present in all types and objects. Set only for an array type or
|
|
-- an array object if a valid pragma Atomic_Components applies to the
|
|
-- type or object. Note that in the case of an object, this flag is
|
|
-- only set on the object if there was an explicit pragma for the
|
|
-- object. In other words, the proper test for whether an object has
|
|
-- atomic components is to see if either the object or its base type
|
|
-- has this flag set. Note that in the case of a type, the pragma will
|
|
-- be chained to the rep item chain of the first subtype in the usual
|
|
-- manner.
|
|
|
|
-- Has_Attach_Handler (synthesized)
|
|
-- Applies to record types that are constructed by the expander to
|
|
-- represent protected types. Returns True if there is at least one
|
|
-- Attach_Handler pragma in the corresponding specification.
|
|
|
|
-- Has_Biased_Representation (Flag139)
|
|
-- Present in discrete types (where it applies to the type'size value),
|
|
-- and to objects (both stand-alone and components), where it applies to
|
|
-- the size of the object from a size or record component clause. In
|
|
-- all cases it indicates that the size in question is smaller than
|
|
-- would normally be required, but that the size requirement can be
|
|
-- satisfied by using a biased representation, in which stored values
|
|
-- have the low bound (Expr_Value (Type_Low_Bound (T)) subtracted to
|
|
-- reduce the required size. For example, a type with a range of 1..2
|
|
-- takes one bit, using 0 to represent 1 and 1 to represent 2.
|
|
--
|
|
-- Note that in the object and component cases, the flag is only set
|
|
-- if the type is unbiased, but the object specifies a smaller size
|
|
-- than the size of the type, forcing biased representation for the
|
|
-- object, but the subtype is still an unbiased type.
|
|
|
|
-- Has_Completion (Flag26)
|
|
-- Present in all entities that require a completion (functions,
|
|
-- procedures, private types, limited private types, incomplete types,
|
|
-- and packages that require a body). Set if the completion has been
|
|
-- encountered and analyzed.
|
|
|
|
-- Has_Completion_In_Body (Flag71)
|
|
-- Present in "Taft amendment types" that is to say incomplete types
|
|
-- whose full declaration appears in the package body.
|
|
|
|
-- Has_Complex_Representation (Flag140) [implementation base type only]
|
|
-- Present in all type entities. Set only for a record base type to
|
|
-- which a valid pragma Complex_Representation applies.
|
|
|
|
-- Has_Component_Size_Clause (Flag68) [implementation base type only]
|
|
-- Present in all type entities. Set if a component size clause is
|
|
-- present for the given type. Note that this flag can be False even
|
|
-- if Component_Size is non-zero (happens in the case of derived types).
|
|
|
|
-- Has_Controlling_Result (Flag98)
|
|
-- Present in E_Function entities. True if The function is a primitive
|
|
-- function of a tagged type which can dispatch on result
|
|
|
|
-- Has_Controlled_Component (Flag43) [base type only]
|
|
-- Present in composite type entities. Indicates that the type has a
|
|
-- component that either is a controlled type, or itself contains a
|
|
-- controlled component (i.e. either Has_Controlled_Component or
|
|
-- Is_Controlled is set for at least one component).
|
|
|
|
-- Has_Convention_Pragma (Flag119)
|
|
-- Present in an entity for which a Convention, Import, or Export
|
|
-- pragma has been given. Used to prevent more than one such pragma
|
|
-- appearing for a given entity (RM B.1(45)).
|
|
|
|
-- Has_Delayed_Freeze (Flag18)
|
|
-- Present in all entities. Set to indicate that an explicit freeze
|
|
-- node must be generated for the entity at its freezing point. See
|
|
-- separate section ("Delayed Freezing and Elaboration") for details.
|
|
|
|
-- Has_Discriminants (Flag5)
|
|
-- Present in all types and subtypes. For types that are allowed to have
|
|
-- discriminants (record types and subtypes, task types and subtypes,
|
|
-- protected types and subtypes, private types, limited private types,
|
|
-- and incomplete types), indicates if the corresponding type or subtype
|
|
-- has a known discriminant part. Always false for all other types.
|
|
|
|
-- Has_Entries (synthesized)
|
|
-- Applies to concurrent types. True if any entries are declared
|
|
-- within the task or protected definition for the type.
|
|
|
|
-- Has_Enumeration_Rep_Clause (Flag66)
|
|
-- Present in enumeration types. Set if an enumeration representation
|
|
-- clause has been given for this enumeration type. Used to prevent more
|
|
-- than one enumeration representation clause for a given type. Note
|
|
-- that this does not imply a representation with holes, since the rep
|
|
-- clause may merely confirm the default 0..N representation.
|
|
|
|
-- Has_External_Tag_Rep_Clause (Flag110)
|
|
-- Present in tagged types. Set if an external_tag rep. clause has been
|
|
-- given for this type. Use to avoid the generation of the default
|
|
-- external_tag.
|
|
|
|
-- Has_Exit (Flag47)
|
|
-- Present in loop entities. Set if the loop contains an exit statement.
|
|
|
|
-- Has_Foreign_Convention (synthesized)
|
|
-- Applies to all entities. Determines if the Convention for the
|
|
-- entity is a foreign convention (i.e. is other than Convention_Ada,
|
|
-- Convention_Intrinsic, Convention_Entry or Convention_Protected).
|
|
|
|
-- Has_Forward_Instantiation (Flag175)
|
|
-- Present in package entities. Set true for packages that contain
|
|
-- instantiations of local generic entities, before the corresponding
|
|
-- generic body has been seen. If a package has a forward instantiation,
|
|
-- we cannot inline subprograms appearing in the same package because
|
|
-- the placement requirements of the instance will conflict with the
|
|
-- linear elaboration of front-end inlining.
|
|
|
|
-- Has_Fully_Qualified_Name (Flag173)
|
|
-- Present in all entities. Set True if the name in the Chars field
|
|
-- has been replaced by the fully qualified name, as used for debug
|
|
-- output. See Exp_Dbug for a full description of the use of this
|
|
-- flag and also the related flag Has_Qualified_Name.
|
|
|
|
-- Has_Gigi_Rep_Item (Flag82)
|
|
-- This flag is set if the rep item chain (referenced by First_Rep_Item
|
|
-- and linked through the Next_Rep_Item chain contains a representation
|
|
-- item that needs to be specially processed by Gigi, i.e. one of the
|
|
-- following items:
|
|
--
|
|
-- Machine_Attribute pragma
|
|
-- Linker_Alias pragma
|
|
-- Linker_Section pragma
|
|
-- Weak_External pragma
|
|
--
|
|
-- If this flag is set, then Gigi should scan the rep item chain to
|
|
-- process any of these items that appear. At least one such item will
|
|
-- be present.
|
|
|
|
-- Has_Homonym (Flag56)
|
|
-- Present in all entities. Set if an entity has a homonym in the same
|
|
-- scope. Used by Gigi to generate unique names for such entities.
|
|
|
|
-- Has_Interrupt_Handler (synthesized)
|
|
-- Applies to all protected types entities. Set if the protected type
|
|
-- definition contains at least one procedure to which a pragma
|
|
-- Interrupt_Handler applies.
|
|
|
|
-- Has_Machine_Radix_Clause (Flag83)
|
|
-- Present in decimal types and subtypes, set if a Machine_Radix
|
|
-- representation clause is present. This flag is used to detect
|
|
-- the error of multiple machine radix clauses for a single type.
|
|
|
|
-- Has_Master_Entity (Flag21)
|
|
-- Present in entities that can appear in the scope stack (see spec
|
|
-- of Sem). It is set if a task master entity (_master) has been
|
|
-- declared and initialized in the corresponding scope.
|
|
|
|
-- Has_Missing_Return (Flag142)
|
|
-- Present in functions and generic functions. Set if there is one or
|
|
-- more missing return statements in the function. This is used to
|
|
-- control wrapping of the body in Exp_Ch6 to ensure that the program
|
|
-- error exeption is correctly raised in this case at runtime.
|
|
|
|
-- Has_Nested_Block_With_Handler (Flag101)
|
|
-- Present in scope entities. Set if there is a nested block within the
|
|
-- scope that has an exception handler and the two scopes are in the
|
|
-- same procedure. This is used by the backend for controlling certain
|
|
-- optimizations to ensure that they are consistent with exceptions.
|
|
-- See documentation in Gigi for further details.
|
|
|
|
-- Has_Non_Standard_Rep (Flag75) [implementation base type only]
|
|
-- Present in all type entities. Set when some representation clause

|
-- or pragma causes the representation of the item to be significantly
|
|
-- modified. In this category are changes of small or radix for a
|
|
-- fixed-point type, change of component size for an array, and record
|
|
-- or enumeration representation clauses, as well as packed pragmas.
|
|
-- All other representation clauses (e.g. Size and Alignment clauses)
|
|
-- are not considered to be significant since they do not affect
|
|
-- stored bit patterns.
|
|
|
|
-- Has_Object_Size_Clause (Flag172)
|
|
-- Present in entities for types and subtypes. Set if an Object_Size
|
|
-- clause has been processed for the type Used to prevent multiple
|
|
-- Object_Size clauses for a given entity.
|
|
|
|
-- Has_Per_Object_Constraint (Flag154)
|
|
-- Present in E_Component entities, true if the subtype of the
|
|
-- component has a per object constraint, i.e. an actual discriminant
|
|
-- value of the form T'Access, where T is the enclosing type.
|
|
|
|
-- Has_Pragma_Controlled (Flag27) [implementation base type only]
|
|
-- Present in access type entities. It is set if a pragma Controlled
|
|
-- applies to the access type.
|
|
|
|
-- Has_Pragma_Elaborate_Body (Flag150)
|
|
-- Present in all entities. Set in compilation unit entities if a
|
|
-- pragma Elaborate_Body applies to the compilation unit.
|
|
|
|
-- Has_Pragma_Inline (Flag157)
|
|
-- Present in all entities. Set for functions and procedures for which
|
|
-- a pragma Inline or Inline_Always applies to the subprogram. Note
|
|
-- subprogram. Note that this flag can be set even if Is_Inlined is
|
|
-- not set. This happens for pragma Inline (if Inline_Active is False)
|
|
-- In other words, the flag Has_Pragma_Inline represents the formal
|
|
-- semantic status, and is used for checking semantic correctness.
|
|
-- The flag Is_Inlined indicates whether inlining is actually active
|
|
-- for the entity.
|
|
|
|
-- Has_Pragma_Pack (Flag121) [implementation base type only]
|
|
-- Present in all entities. It indicates that a valid pragma Pack was
|
|
-- was given for the type. Note that this flag is not inherited by a
|
|
-- derived type. See also the Is_Packed flag.
|
|
|
|
-- Has_Pragma_Pure_Function (Flag179)
|
|
-- Present in subprogram entities. It indicates that a valid pragma
|
|
-- Pure_Function was given for the entity. In some cases, we need to
|
|
-- know that Is_Pure was explicitly set using this pragma.
|
|
|
|
-- Has_Pragma_Unreferenced (Flag180)
|
|
-- Present in all entities. Set if a valid pragma Unreferenced applies
|
|
-- to the pragma, indicating that no warning should be given if the
|
|
-- entity has no references, but a warning should be given if it is
|
|
-- in fact referenced.
|
|
|
|
-- Has_Primitive_Operations (Flag120) [base type only]
|
|
-- Present in all type entities. Set if at least one primitive operation
|
|
-- is defined for the type.
|
|
|
|
-- Has_Private_Ancestor (synthesized)
|
|
-- Applies to all type and subtype entities. Returns True if at least
|
|
-- one ancestor is private, and otherwise False if there are no private
|
|
-- ancestors.
|
|
|
|
-- Has_Private_Declaration (Flag155)
|
|
-- Present in all entities. Returns True if it is the defining entity
|
|
-- of a private type declaration or its corresponding full declaration.
|
|
-- This flag is thus preserved when the full and the partial views are
|
|
-- exchanged, to indicate if a full type declaration is a completion.
|
|
-- Used for semantic checks in E.4 (18), and elsewhere.
|
|
|
|
-- Has_Qualified_Name (Flag161)
|
|
-- Present in all entities. Set True if the name in the Chars field
|
|
-- has been replaced by its qualified name, as used for debug output.
|
|
-- See Exp_Dbug for a full description of qualification requirements.
|
|
-- For some entities, the name is the fully qualified name, but there
|
|
-- are exceptions. In particular, for local variables in procedures,
|
|
-- we do not include the procedure itself or higher scopes. See also
|
|
-- the flag Has_Fully_Qualified_Name, which is set if the name does
|
|
-- indeed include the fully qualified name.
|
|
|
|
-- Has_Record_Rep_Clause (Flag65) [implementation base type only]
|
|
-- Present in record types. Set if a record representation clause has
|
|
-- been given for this record type. Used to prevent more than one such
|
|
-- clause for a given record type. Note that this is initially cleared
|
|
-- for a derived type, even though the representation is inherited. See
|
|
-- also the flag Has_Specified_Layout.
|
|
|
|
-- Has_Recursive_Call (Flag143)
|
|
-- Present in procedures. Set if a direct parameterless recursive call
|
|
-- is detected while analyzing the body. Used to activate some error
|
|
-- checks for infinite recursion.
|
|
|
|
-- Has_Size_Clause (Flag29)
|
|
-- Present in entities for types and objects. Set if a size clause is
|
|
-- present for the entity. Used to prevent multiple Size clauses for a
|
|
-- given entity. Note that it is always initially cleared for a derived
|
|
-- type, even though the Size for such a type is inherited from a Size
|
|
-- clause given for the parent type.
|
|
|
|
-- Has_Small_Clause (Flag67)
|
|
-- Present in ordinary fixed point types (but not subtypes). Indicates
|
|
-- that a small clause has been given for the entity. Used to prevent
|
|
-- multiple Small clauses for a given entity. Note that it is always
|
|
-- initially cleared for a derived type, even though the Small for such
|
|
-- a type is inherited from a Small clause given for the parent type.
|
|
|
|
-- Has_Specified_Layout (Flag100) [implementation base type only]
|
|
-- Present in all type entities. Set for a record type or subtype if
|
|
-- the record layout has been specified by a record representation
|
|
-- clause. Note that this differs from the flag Has_Record_Rep_Clause
|
|
-- in that it is inherited by a derived type. Has_Record_Rep_Clause is
|
|
-- used to indicate that the type is mentioned explicitly in a record
|
|
-- representation clause, and thus is not inherited by a derived type.
|
|
-- This flag is always False for non-record types.
|
|
|
|
-- Has_Storage_Size_Clause (Flag23) [implementation base type only]
|
|
-- Present in task types and access types. It is set if a Storage_Size
|
|
-- clause is present for the type. Used to prevent multiple clauses for
|
|
-- one type. Note that this flag is initially cleared for a derived type
|
|
-- even though the Storage_Size for such a type is inherited from a
|
|
-- Storage_Size clause given for the parent type. Note that in the case
|
|
-- of access types, this flag is present only in the root type, since a
|
|
-- storage size clause cannot be given to a derived type.
|
|
|
|
-- Has_Subprogram_Descriptor (Flag93)
|
|
-- This flag is set on entities for which zero-cost exception subprogram
|
|
-- descriptors can be generated (subprograms and library level package
|
|
-- declarations and bodies). It indicates that a subprogram descriptor
|
|
-- has been generated, and is used to suppress generation of multiple
|
|
-- descriptors (e.g. when instantiating generic bodies).
|
|
|
|
-- Has_Task (Flag30) [base type only]
|
|
-- Present in all type entities. Set on task types themselves, and also
|
|
-- (recursively) on any composite type which has a component for which
|
|
-- Has_Task is set. The meaning is that an allocator of such an object
|
|
-- must create the required tasks. Note that the flag is not set on
|
|
-- access types, even if they designate an object that Has_Task.
|
|
|
|
-- Has_Unchecked_Union (Flag123) [base type only]
|
|
-- Present in all type entities. Set on unchecked unions themselves
|
|
-- and (recursively) on any composite type which has a component for
|
|
-- which Has_Unchecked_Union is set. The meaning is that a comparison
|
|
-- operation for the type is not permitted. Note that the flag is not
|
|
-- set on access types, even if they designate an object that has
|
|
-- the flag Has_Unchecked_Union set.
|
|
|
|
-- Has_Unknown_Discriminants (Flag72)
|
|
-- Present in all type entities. Types can have unknown discriminants
|
|
-- either from their declaration or through type derivation. The use
|
|
-- of this flag exactly meets the spec in RM 3.7(26). Note that all
|
|
-- class-wide types are considered to have unknown discriminants.
|
|
|
|
-- Has_Volatile_Components (Flag87) [implementation base type only]
|
|
-- Present in all types and objects. Set only for an array type or
|
|
-- array object if a valid pragma Volatile_Components or a valid
|
|
-- pragma Atomic_Components applies to the type or object. Note that
|
|
-- in the case of an object, this flag is only set on the object if
|
|
-- there was an explicit pragma for the object. In other words, the
|
|
-- proper test for whether an object has volatile components is to
|
|
-- see if either the object or its base type has this flag set. Note
|
|
-- that in the case of a type the pragma will be chained to the rep
|
|
-- item chain of the first subtype in the usual manner.
|
|
|
|
-- Hiding_Loop_Variable (Node8)
|
|
-- Present in variables. Set only if a variable of a discrete type is
|
|
-- hidden by a loop variable in the same local scope, in which case
|
|
-- the Hiding_Loop_Variable field of the hidden variable points to
|
|
-- the E_Loop_Variable entity doing the hiding. Used in processing
|
|
-- warning messages if the hidden variable turns out to be unused
|
|
-- or is referenced without being set.
|
|
|
|
-- Homonym (Node4)
|
|
-- Present in all entities. Link for list of entities that have the
|
|
-- same source name and that are declared in the same or enclosing
|
|
-- scopes. Homonyms in the same scope are overloaded. Used for name
|
|
-- resolution and for the generation of debugging information.
|
|
|
|
-- Implementation_Base_Type (synthesized)
|
|
-- Applies to all types. Similar to Base_Type, but never returns a
|
|
-- private type when applied to a non-private type. Instead in this
|
|
-- case, it always returns the Representation_Type of the base type
|
|
-- in this case, so that we still have a concrete type. Note: it is
|
|
-- allowed to apply Implementation_Base_Type to other than a type,
|
|
-- in which case it simply returns the entity unchanged.
|
|
|
|
-- In_Package_Body (Flag48)
|
|
-- Set on the entity that denotes the package (the defining occurrence
|
|
-- of the package declaration) while analyzing and expanding the package
|
|
-- body. Reset on completion of analysis/expansion.
|
|
|
|
-- In_Private_Part (Flag45)
|
|
-- Present in package entities. Flag is set to indicate that the
|
|
-- private part is being analyzed. The flag is reset at the end of the
|
|
-- package declaration.
|
|
|
|
-- Inner_Instances (Elist23)
|
|
-- Present in generic units. Contains element list of units that are
|
|
-- instantiated within the given generic. Used to diagnose circular
|
|
-- instantiations.
|
|
|
|
-- Interface_Name (Node21)
|
|
-- Present in exceptions, functions, procedures, variables, constants,
|
|
-- and packages. Set to Empty unless an export, import, or interface
|
|
-- name pragma has explicitly specified an external name, in which
|
|
-- case it references an N_String_Literal node for the specified
|
|
-- exteral name. In the case of exceptions, the field is set by
|
|
-- Import_Exception/Export_Exception (which can be used in OpenVMS
|
|
-- versions only). Note that if this field is Empty, and Is_Imported
|
|
-- or Is_Exported is set, then the default interface name is the name
|
|
-- of the entity, cased in a manner that is appropriate to the system
|
|
-- in use. Note that Interface_Name is ignored if an address clause
|
|
-- is present (since it is meaningless in this case).
|
|
--
|
|
-- An additional special case usage of this field is in JGNAT for
|
|
-- E_Component and E_Discriminant. JGNAT allows these entities to
|
|
-- be imported by specifying pragma Import within a component's
|
|
-- containing record definition. This supports interfacing to
|
|
-- object fields defined within Java classes, and such pragmas
|
|
-- are generated by the jvm2ada binding generator tool whenever
|
|
-- it processes classes with public object fields. A pragma Import
|
|
-- for a component can define the External_Name of the imported
|
|
-- Java field (which is generally needed, because Java names are
|
|
-- case sensitive).
|
|
--
|
|
-- In_Use (Flag8)
|
|
-- Present in packages and types. Set when analyzing a use clause for
|
|
-- the corresponding entity. Reset at end of corresponding declarative
|
|
-- part. The flag on a type is also used to determine the visibility of
|
|
-- the primitive operators of the type.
|
|
|
|
-- Is_Abstract (Flag19)
|
|
-- Present in all types, and also for functions and procedures. Set
|
|
-- for abstract types and abstract subprograms.
|
|
|
|
-- Is_Access_Constant (Flag69)
|
|
-- Present in access types and subtypes. Indicates that the keyword
|
|
-- constant was present in the access type definition.
|
|
|
|
-- Is_Access_Type (synthesized)
|
|
-- Applies to all entities, true for access types and subtypes
|
|
|
|
-- Is_Aliased (Flag15)
|
|
-- Present in objects whose declarations carry the keyword aliased,
|
|
-- and on record components that have the keyword.
|
|
|
|
-- Is_Always_Inlined (synthesized)
|
|
-- Present in subprograms. True if there is a pragma Inline_Always for
|
|
-- the subprogram.
|
|
|
|
-- Is_AST_Entry (Flag132)
|
|
-- Present in entry entities. Set if a valid pragma AST_Entry applies
|
|
-- to the entry. This flag can only be set in OpenVMS versions of GNAT.
|
|
-- Note: we also allow the flag to appear in entry families, but given
|
|
-- the current implementation of the pragma AST_Entry, this flag will
|
|
-- always be False in entry families.
|
|
|
|
-- Is_Atomic (Flag85)
|
|
-- Present in all type entities, and also in constants, components and
|
|
-- variables. Set if a pragma Atomic or Shared applies to the entity.
|
|
-- In the case of private and incomplete types, this flag is set in
|
|
-- both the partial view and the full view.
|
|
|
|
-- Is_Array_Type (synthesized)
|
|
-- Applies to all entities, true for array types and subtypes
|
|
|
|
-- Is_Asynchronous (Flag81)
|
|
-- Present in all type entities and in procedure entities. Set
|
|
-- if a pragma Asynchronous applies to the entity.
|
|
|
|
-- Is_Bit_Packed_Array (Flag122) [implementation base type only]
|
|
-- Present in all entities. This flag is set for a packed array
|
|
-- type that is bit packed (i.e. the component size is known by the
|
|
-- front end and is in the range 1-7, 9-15, or 17-31). Is_Packed is
|
|
-- always set if Is_Bit_Packed_Array is set, but it is possible for
|
|
-- Is_Packed to be set without Is_Bit_Packed_Array or the case of an
|
|
-- array having one or more index types that are enumeration types
|
|
-- with non-standard enumeration representations.
|
|
|
|
-- Is_Boolean_Type (synthesized)
|
|
-- Applies to all entities, true for boolean types and subtypes,
|
|
-- i.e. Standard.Boolean and all types ultimately derived from it.

|
|
-- Applies to all type entities. Returns true if the entity is
|
|
-- a by copy type (RM 6.2(3)).
|
|
|
|
-- Is_By_Reference_Type (synthesized)
|
|
-- Applies to all type entities. True if the type is required to
|
|
-- be passed by reference, as defined in (RM 6.2(4-9)).
|
|
|
|
-- Is_Called (Flag102)
|
|
-- Present in subprograms. Returns true if the subprogram is called
|
|
-- in the unit being compiled or in a unit in the context. Used for
|
|
-- inlining.
|
|
|
|
-- Is_Character_Type (Flag63)
|
|

|
|
-- Is_Child_Unit (Flag73)
|

|
|
-- Applies to all entities, true for class wide types and subtypes
|
|
|
|
-- Is_Compilation_Unit (Flag149)
|
|
-- Present in all entities. Set if the entity is a package or subprogram
|
|
-- entity for a compilation unit other than a subunit (since we treat
|
|
-- subunits as part of the same compilation operation as the ultimate
|
|
-- parent, we do not consider them to be separate units for this flag).
|
|
|
|
-- Is_Completely_Hidden (Flag103)
|
|
-- A flag set on an E_Discriminant entity. This flag can be set only
|
|
-- for girder discriminants of untagged types. When set, the entity
|
|
-- is a girder discriminant of a derived untagged type which is not
|
|
-- directly visible in the derived type because the derived type or
|
|
-- one of its ancestors have renamed the discriminants in the root
|
|
-- type. Note that there are girder discriminants which are not
|
|
-- Completely_Hidden (eg the discriminants of a root type).
|
|
|
|
-- Is_Composite_Type (synthesized)
|
|
-- Applies to all entities, true for all composite types and
|
|
-- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
|
|
-- not both) is true of any type.
|
|
|
|
-- Is_Concurrent_Record_Type (Flag20)
|
|
-- Present in record types and subtypes. Set if the type was created
|
|
-- by the expander to represent a task or protected type. For every
|
|
-- concurrent type, such as record type is constructed, and task and
|
|
-- protected objects are instances of this record type at runtime
|
|
-- (Gigi will replace declarations of the concurrent type using the
|

|
-- for further details.

|
-- Set if the type or subtype is constrained.
|
|
|
|
-- Is_Constr_Subt_For_U_Nominal (Flag80)

|
|
-- that the constructed subtype itself will be constrained.

-- Is_Constr_Subt_For_UN_Aliased (Flag141)
|
|
-- This flag can only be set if Is_Constr_Subt_For_U_Nominal is set. It
|

-- indicates that in addition the object concerned is aliased. This flag
|
|
-- is used by Gigi to determine whether a template must be constructed.
|
|
|
|
-- Is_Constructor (Flag76)
|
|
-- Present in function and procedure entities. Set if a pragma
|
|
-- CPP_Constructor applies to the subprogram.

|
|
-- Present in all type entities. Indicates that the type is controlled,
|
|

|
|
-- Ada.Finalization.Limited_Controlled.
|
|
|
|
-- Is_Controlling_Formal (Flag97)
|
|

|
|
-- creates to compute discriminant-dependent dynamic size/offset values.

|
-- up the test for the need to replace references in Exp_Ch2.
|
|
|
|
-- Is_Exported (Flag99)
|
|
-- Present in all entities. Set if the entity is exported. For now we
|
|
-- only allow the export of constants, exceptions, functions, procedures
|
|
-- and variables, but that may well change later on. Exceptions can only

-- Is_First_Subtype (Flag70)
|
|
-- Present in all entities. True for first subtypes (RM 3.2.1(6)),
|
|
-- i.e. the entity in the type declaration that introduced the type.

-- Applies to all entities, true for IN, IN OUT and OUT parameters
|
|
|
|
-- Is_Formal_Subprogram (Flag111)
|
|
-- Defined on all entities, true for generic formal subprograms.
|
|
|
|
-- Is_For_Access_Subtype (Flag118)
|
|
-- Present in E_Private_Subtype and E_Record_Subtype entities.
|
|
-- Means the sole purpose of the type is to be designated by an
|
|
-- Access_Subtype and hence should not be expanded into components
|
|
-- because the type may not have been found or frozen yet.
|
|
|
|
-- Is_Frozen (Flag4)
|
|
-- Present in all type entities. Set if the type has been frozen.
|
|
|
|
-- Is_Generic_Actual_Type (Flag94)
|
|
-- Present in the subtype declaration that renames the generic formal
|
|
-- as a subtype of the actual. Guarantees that the subtype is not static
|
|
-- within the instance.
|
|
|
|
-- Is_Generic_Instance (Flag130)
|
|
-- Present in all entities. Set to indicate that the entity is an
|
|
-- instance of a generic unit.
|
|
|
|
-- Is_Generic_Type (Flag13)
|
|
-- Present in types which are generic formal types. Such types have an
|
|
-- Ekind that corresponds to their classification, so the Ekind cannot
|
|
-- be used to identify generic types.
|
|
|
|
-- Is_Generic_Unit (synthesized)
|
|
-- Applies to all entities. Yields True for a generic unit (generic
|
|
-- package, generic function, generic procedure), and False for all
|
|
-- other entities.
|
|
|
|
-- Is_Hidden (Flag57)
|
|
-- Present in all entities. Set true for all entities declared in the
|
|
-- private part or body of a package. Also marks generic formals of a
|
|
-- formal package declared without a box. For library level entities,
|
|
-- this flag is set if the entity is not publicly visible.
|
|
|
|
-- Is_Hidden_Open_Scope (Flag171)
|
|
-- Present in all entities. Set true for a scope that contains the
|
|
-- instantiation of a child unit, and whose entities are not visible
|
|
-- during analysis of the instance.
|
|
|
|
-- Is_Immediately_Visible (Flag7)
|
|
-- Present in all entities. Set if entity is immediately visible, i.e.
|
|
-- is defined in some currently open scope (RM 8.3(4)).
|
|
|
|
-- Is_Imported (Flag24)
|
|
-- Present in all entities. Set if the entity is imported. For now we
|
|
-- only allow the import of exceptions, functions, procedures, packages.
|
|
-- and variables. Exceptions can only be imported in the OpenVMS and
|
|
-- Java VM implementations of GNAT. Packages and types can only be
|
|
-- imported in the Java VM implementation.
|
|
|
|
-- Is_Incomplete_Or_Private_Type (synthesized)
|
|
-- Applies to all entities, true for private and incomplete types
|
|
|
|
-- Is_Indefinite_Subtype (synthesized)
|
|
-- Applies to all entities for types and subtypes. Determines if given
|
|
-- entity is an unconstrained array type or subtype, a discriminated
|
|
-- record type or subtype with no initial discriminant values or a
|
|
-- class wide type or subtype.
|
|
|
|
-- Is_Inlined (Flag11)
|
|
-- Present in all entities. Set for functions and procedures which are
|
|
-- to be inlined. For subprograms created during expansion, this flag
|
|
-- may be set directly by the expander to request inlining. Also set
|
|
-- for packages that contain inlined subprograms, whose bodies must be
|
|
-- be compiled. Is_Inlined is also set on generic subprograms and is
|
|
-- inherited by their instances. It is also set on the body entities
|
|
-- of inlined subprograms. See also Has_Pragma_Inline.
|
|
|
|
-- Is_Instantiated (Flag126)
|
|
-- Present in generic packages and generic subprograms. Set if the unit
|
|
-- is instantiated from somewhere in the extended main source unit. This
|
|
-- flag is used to control warnings about the unit being uninstantiated.
|
|
-- Also set in a package that is used as an actual for a generic package
|
|
-- formal in an instantiation. Also set on a parent instance, in the
|
|
-- instantiation of a child, which is implicitly declared in the parent.
|
|
|
|
-- Is_Integer_Type (synthesized)
|
|
-- Applies to all entities, true for integer types and subtypes
|
|
|
|
-- Is_Internal (Flag17)
|
|
-- Present in all entities. Set to indicate an entity created during
|
|
-- semantic processing (e.g. an implicit type). Need more documentation
|
|
-- on this one! ???
|
|
|
|
-- Is_Interrupt_Handler (Flag89)
|
|
-- Present in protected procedures. Set if a pragma Interrupt_Handler
|
|
-- applies to the procedure (which must be parameterless).
|
|
|
|
-- Is_Intrinsic_Subprogram (Flag64)
|
|
-- Present in functions and procedures. It is set if a valid pragma
|
|
-- Interface or Import is present for this subprogram specifying pragma
|
|
-- Intrinsic. Valid means that the name and profile of the subprogram
|
|
-- match the requirements of one of the recognized intrinsic subprograms
|
|
-- (see package Sem_Intr for details). Note: the value of Convention for
|
|
-- such an entity will be set to Convention_Intrinsic, but it is the
|
|
-- setting of Is_Intrinsic_Subprogram, NOT simply having convention set
|
|
-- to intrinsic, which causes intrinsic code to be generated.
|
|
|
|
-- Is_Itype (Flag91)
|
|
-- Present in all entities, set for Itypes. If it is set, then the
|
|
-- declaration for the type does not appear explicitly in the tree.
|
|
-- Instead gigi will elaborate the type when it is first used.
|
|
-- Has_Delayed_Freeze can be set for Itypes, and the meaning is that
|
|
-- the first use (the one which causes the type to be defined) will
|
|
-- be the freeze node. Note that an important restriction on Itypes
|
|
-- is that the first use of such a type (the one that causes it to be
|
|
-- defined) must be in the same scope as the type.
|
|
|
|
-- Is_Known_Valid (Flag170)
|
|
-- Present in all entities. Relevant for types (and subtype) and
|
|
-- for objects (and enumeration literals) of a discrete type.
|
|
--
|
|
-- The purpose of this flag is to implement the requirement stated
|
|
-- in (RM 13.9.1(9-11)) which require that the use of possibly invalid
|
|
-- values may not cause programs to become erroneous. See the function
|
|
-- Exp_Util.Expr_Known_Valid for further details. Note that the setting
|
|
-- is conservative, in the sense that if the flag is set, it must be
|
|
-- right. If the flag is not set, nothing is known about the validity.
|
|
--
|
|
-- For enumeration literals, the flag is always set, since clearly
|
|
-- an enumeration literal represents a valid value. Range checks
|
|
-- where necessary will ensure that this valid value is appropriate.
|
|
--
|
|
-- For objects, the flag indicates the state of knowledge about the
|
|
-- current value of the object. This may be modified during expansion,
|
|
-- and thus the final value is not relevant to gigi.
|
|
--
|
|
-- For types and subtypes, the flag is set if all possible bit patterns
|
|
-- of length Object_Size (i.e. Esize of the type) represent valid values
|
|
-- of the type. In general for such tytpes, all values are valid, the
|
|
-- only exception being the case where an object of the type has an
|
|
-- explicit size that is greater than Object_Size.
|
|
--
|
|
-- For non-discrete objects, the setting of the Is_Known_Valid flag is
|
|
-- not defined, and is not relevant, since the considerations of the
|
|
-- requirement in (RM 13.9.1(9-11)) do not apply.
|
|
|
|
-- Is_Limited_Composite (Flag106)
|
|
-- Present in all entities. True for composite types that have a
|
|
-- limited component. Used to enforce the rule that operations on
|
|
-- the composite type that depend on the full view of the component
|
|
-- do not become visible until the immediate scope of the composite
|
|
-- type itself (RM 7.3.1 (5)).
|
|
|
|
-- Is_Limited_Record (Flag25)
|
|
-- Present in all entities. Set to true for record (sub)types if the
|
|
-- record is declared to be limited. Note that this flag is not set
|
|
-- simply because some components of the record are limited.
|
|
|
|
-- Is_Limited_Type (synthesized)
|
|
-- Applies to all entities. True if entity is a limited type (limited
|
|
-- private type, task type, protected type, composite containing a
|
|
-- limited component, or a subtype of any of these types).
|
|
|
|
-- Is_Machine_Code_Subprogram (Flag137)
|
|
-- Present in subprogram entities. Set to indicate that the subprogram
|
|
-- is a machine code subprogram (i.e. its body includes at least one
|
|
-- code statement). Also indicates that all necessary semantic checks
|
|
-- as required by RM 13.8 have been performed.
|
|
|
|
-- Is_Non_Static_Subtype (Flag109)
|
|
-- This flag is present in all type and subtype entities. It is set in
|
|
-- some (but not all) cases in which a subtype is known to be non-static.
|
|
-- Before this flag was added, the computation of whether a subtype was
|
|
-- static was entirely synthesized, by looking at the bounds, and the
|
|
-- immediate subtype parent. However, this method does not work for some
|
|
-- Itypes that have no parent set (and the only way to find the immediate
|
|
-- subtype parent is to go through the tree). For now, this flay is set
|
|
-- conservatively, i.e. if it is set then for sure the subtype is non-
|
|
-- static, but if it is not set, then the type may or may not be static.
|
|
-- Thus the test for a static subtype is that this flag is clear AND
|
|
-- that the bounds are static AND that the parent subtype (if available
|
|
-- to be tested) is static. Eventually we should make sure this flag
|
|
-- is always set right, at which point, these comments can be removed,
|
|
-- and the tests for static subtypes greatly simplified.
|
|
|
|
-- Is_Null_Init_Proc (Flag178)
|
|
-- Present in procedure entities. Set for generated init_proc procedures
|
|
-- (used to initialize composite types), if the code for the procedure
|
|
-- is null (i.e. is a return and nothing else). Such null initialization
|
|
-- procedures are generated in case some client is compiled using the
|
|
-- Initialize_Scalars pragma, generating a call to this null procedure,
|
|
-- but there is no need to call such procedures within a compilation
|
|
-- unit, and this flag is used to suppress such calls.
|
|
|
|
-- Is_Numeric_Type (synthesized)
|
|
-- Applies to all entities, true for all numeric types and subtypes
|
|
-- (integer, fixed, float).
|
|
|
|
-- Is_Object (synthesized)
|
|
-- Applies to all entities, true for entities representing objects,
|
|
-- including generic formal parameters.
|
|
|
|
-- Is_Optional_Parameter (Flag134)
|
|
-- Present in parameter entities. Set if the parameter is specified as
|
|
-- optional by use of a First_Optional_Parameter argument to one of the
|
|
-- extended Import pragmas. Can only be set for OpenVMS versions of GNAT.
|
|
|
|
-- Is_Ordinary_Fixed_Point_Type (synthesized)
|
|
-- Applies to all entities, true for ordinary fixed point types
|
|
-- and subtypes
|
|
|
|
-- Is_Package (synthesized)
|
|
-- Applies to all entities. True for packages and generic packages.
|
|
-- False for all other entities.
|
|
|
|
-- Is_Package_Body_Entity (Flag160)
|
|
-- Present in all entities. Set for entities defined at the top level
|
|
-- of a package body. Used to control externally generated names.
|
|
|
|
-- Is_Packed (Flag51) [implementation base type only]
|
|
-- Present in all type entities. This flag is set only for record and
|
|
-- array types which have a packed representation. There are three
|
|
-- cases which cause packing:
|
|
--
|
|
-- 1. Explicit use of pragma Pack for an array of package components
|
|
-- 2. Explicit use of pragma Pack to pack a record
|
|
-- 4. Setting Component_Size of an array to a bit-packable value
|
|
-- 3. Indexing an array with a non-standard enumeration type.
|
|
--
|
|
-- For records, Is_Packed is always set if Has_Pack_Pragma is set,
|
|
-- and can also be set on its own in a derived type which inherited
|
|
-- its packed status.
|
|
--
|
|
-- For arrays, Is_Packed is set if an array is bit packed (i.e. the
|
|
-- component size is known at compile time and is 1-7, 9-15 or 17-31),
|
|
-- or if the array has one or more index types that are enumeration
|
|
-- types with non-standard representations (in GNAT, we store such
|
|
-- arrays compactly, using the Pos of the enumeration type value).
|
|
--
|
|
-- As for the case of records, Is_Packed can be set on its own for a
|
|
-- derived type, with the same dual before/after freeze meaning.
|
|
-- Is_Packed can also be set as the result of an explicit component
|
|
-- size clause that specifies an appropriate component size.
|
|
--
|
|
-- In the bit packed array case, Is_Bit_Packed_Array will be set in
|
|
-- the bit packed case once the array type is frozen.
|
|
--
|
|
-- Before an array type is frozen, Is_Packed will always be set if
|
|
-- Has_Pack_Pragma is set. Before the freeze point, it is not possible
|
|
-- to know the component size, since the component type is not frozen
|
|
-- until the array type is frozen. Thus Is_Packed for an array type
|
|
-- before it is frozen means that packed is required. Then if it turns
|
|
-- out that the component size is not suitable for bit packing, the
|
|
-- Is_Packed flag gets turned off.
|
|
|
|
-- Is_Packed_Array_Type (Flag138)
|
|
-- Present in all entities. This flag is set on the entity for the type
|
|
-- used to implement a packed array (either a modular type, or a subtype
|
|
-- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
|
|
-- if the type appears in the Packed_Array_Type field of some other type
|
|
-- entity. It is used by Gigi to activate the special processing for such
|
|
-- types (unchecked conversions that would not otherwise be allowed are
|
|
-- allowed for such types). If the Is_Packed_Array_Type flag is set in
|
|
-- an entity, then the Original_Array_Type field of this entity points
|
|
-- to the original array type for which this is the packed array type.
|
|
|
|
-- Is_Potentially_Use_Visible (Flag9)
|
|
-- Present in all entities. Set if entity is potentially use visible,
|
|
-- i.e. it is defined in a package that appears in a currently active
|
|
-- use clause (RM 8.4(8)). Note that potentially use visible entities
|
|
-- are not necessarily use visible (RM 8.4(9-11)).
|
|
|
|
-- Is_Preelaborated (Flag59)
|
|
-- Present in all entities, set in E_Package and E_Generic_Package
|
|
-- entities to which a pragma Preelaborate is applied, and also in
|
|
-- all entities within such packages. Note that the fact that this
|
|
-- flag is set does not necesarily mean that no elaboration code is
|
|
-- generated for the package.
|
|
|
|
-- Is_Private_Composite (Flag107)
|
|
-- Present in composite types that have a private component. Used to
|
|
-- enforce the rule that operations on the composite type that depend
|
|
-- on the fulll view of the component, do not become visible until the
|
|
-- immediate scope of the composite type itself (7.3.1 (5)). Both this
|
|
-- flag and Is_Limited_Composite are needed.
|
|
|
|
-- Is_Private_Descendant (Flag53)
|
|
-- Present in entities that can represent library units (packages,
|
|
-- functions, procedures). Set if the library unit is itself a private
|
|
-- child unit, or if it is the descendent of a private child unit.
|
|
|
|
-- Is_Private_Type (synthesized)
|
|
-- Applies to all entities, true for private types and subtypes,
|
|
-- as well as for record with private types as subtypes
|
|
|
|
-- Is_Protected_Type (synthesized)
|
|
-- Applies to all entities, true for protected types and subtypes
|
|
|
|
-- Is_Psected (Flag153)
|
|
-- Present in entities for objects, true if a valid Psect_Object
|
|
-- pragma applies to the object. Used to detect duplicate pragmas.
|
|
|
|
-- Is_Public (Flag10)
|
|
-- Present in all entities. Set to indicate that an entity defined in
|
|
-- one compilation unit can be referenced from other compilation units.
|
|
-- If this reference causes a reference in the generated variable, for
|
|
-- example in the case of a variable name, then Gigi will generate an
|
|
-- appropriate external name for use by the linker.
|
|
|
|
-- Is_Protected_Private (synthesized)
|
|
-- Applies to a record component. Returns true if this component
|
|
-- is used to represent a private declaration of a protected type.
|
|
|
|
-- Is_Protected_Record_Type (synthesized)
|
|
-- Applies to all entities, true if Is_Concurrent_Record_Type
|
|
-- Corresponding_Concurrent_Type is a protected type.
|
|
|
|
-- Is_Pure (Flag44)
|
|
-- Present in all entities. Set in all entities of a unit to which a
|
|
-- pragma Pure is applied, and also set for the entity of the unit
|
|
-- itself. In addition, this flag may be set for any other functions
|
|
-- or procedures that are known to be side effect free, so in the case
|
|
-- of subprograms, the Is_Pure flag may be used by the optimizer to
|
|
-- imply that it can assume freedom from side effects (other than those
|
|
-- resulting from assignment to out parameters, or to objects designated
|
|
-- by access parameters).
|
|
|
|
-- Is_Real_Type (synthesized)
|
|
-- Applies to all entities, true for real types and subtypes
|
|
|
|
-- Is_Record_Type (synthesized)
|
|
-- Applies to all entities, true for record types and subtypes,
|
|
-- includes class-wide types and subtypes (which are also records)
|
|
|
|
-- Is_Remote_Call_Interface (Flag62)
|
|
-- Present in all entities, set in E_Package and E_Generic_Package
|
|
-- entities to which a pragma Remote_Call_Interace is applied, and
|
|
-- also in all entities within such packages.
|
|
|
|
-- Is_Remote_Types (Flag61)
|
|
-- Present in all entities, set in E_Package and E_Generic_Package
|
|
-- entities to which a pragma Remote_Types is applied, and also in
|
|
-- all entities within such packages.
|
|
|
|
-- Is_Renaming_Of_Object (Flag112)
|
|
-- Present in all entities, set only for a variable or constant for
|
|
-- which the Renamed_Object field is non-empty and for which the
|
|
-- renaming is handled by the front end, by macro substitution of
|
|
-- a copy of the (evaluated) name tree whereever the variable is used.
|
|
|
|
-- Is_Return_By_Reference_Type (synthesized)
|
|
-- Applies to all type entities. True if the type is required to
|
|
-- be returned by reference, as defined in 6.5(11-16).
|
|
|
|
-- Is_Scalar_Type (synthesized)
|
|
-- Applies to all entities, true for scalar types and subtypes
|
|
|
|
-- Is_Shared_Passive (Flag60)
|
|
-- Present in all entities, set in E_Package and E_Generic_Package
|
|
-- entities to which a pragma Shared_Passive is applied, and also in
|
|
-- all entities within such packages.
|
|
|
|
-- Is_Statically_Allocated (Flag28)
|
|
-- Present in all entities. This can only be set True for exception,
|
|
-- variable, constant, and type/subtype entities. If the flag is set,
|
|
-- then the variable or constant must be allocated statically rather
|
|
-- than on the local stack frame. For exceptions, the meaning is that
|
|
-- the exception data should be allocated statically (and indeed this
|
|
-- flag is always set for exceptions, since exceptions do not have
|
|
-- local scope). For a type, the meaning is that the type must be
|
|
-- elaborated at the global level rather than locally. No type marked
|
|
-- with this flag may depend on a local variable, or on any other type
|
|
-- which does not also have this flag set to True. For a variable or
|
|
-- or constant, if the flag is set, then the type of the object must
|
|
-- either be declared at the library level, or it must also have the
|
|
-- flag set (since to allocate the oject statically, its type must
|
|
-- also be elaborated globally).
|
|
|
|
-- Is_Subprogram (synthesized)
|
|
-- Applies to all entities, true for bodies of functions, procedures
|
|
-- and operators.
|
|
|
|
-- Is_String_Type (synthesized)
|
|
-- Applies to all type entities. Determines if the given type is a
|
|
-- string type, i.e. it is directly a string type or string subtype,
|
|
-- or a string slice type, or an array type with one dimension and a
|
|
-- component type that is a character type.
|
|
|
|
-- Is_Tag (Flag78)
|
|
-- Present in E_Component. For regular tagged type this flag is set on
|
|
-- the tag component (whose name is Name_uTag) and for CPP_Class tagged
|
|
-- types, this flag marks the pointer to the main vtable (i.e. the one
|
|
-- to be extended by derivation)
|
|
|
|
-- Is_Tagged_Type (Flag55)
|
|
-- Present in all entities, true for an entity for a tagged type.
|
|
|
|
-- Is_Task_Record_Type (synthesized)
|
|
-- Applies to all entities, true if Is_Concurrent_Record_Type
|
|
-- Corresponding_Concurrent_Type is a task type.
|
|
|
|
-- Is_Task_Type (synthesized)
|
|
-- Applies to all entities, true for task types and subtypes
|
|
|
|
-- Is_True_Constant (Flag163)
|
|
-- This flag is set in constants and variables which have an initial
|
|
-- value specified but which are never assigned, partially or in the
|
|
-- whole. For variables, it means that the variable was initialized
|
|
-- but never modified, and hence can be treated as a constant by the
|
|
-- code generator. For a constant, it means that the constant was not
|
|
-- modified by generated code (e.g. to set a discriminant in an init
|
|
-- proc). Assignments by user or generated code will reset this flag.
|
|
|
|
-- Is_Type (synthesized)
|
|
-- Applies to all entities, true for a type entity
|
|
|
|
-- Is_Unchecked_Union (Flag117)
|
|
-- Present in all entities. Set only in record types to which the
|
|
-- pragma Unchecked_Union has been validly applied.
|
|
|
|
-- Is_Unsigned_Type (Flag144)
|
|
-- Present in all types, but can be set only for discrete and fixed-point
|
|
-- type and subtype entities. This flag is only valid if the entity is
|
|
-- frozen. If set it indicates that the representation is known to be
|
|
-- unsigned (i.e. that no negative values appear in the range). This is
|
|
-- normally just a reflection of the lower bound of the subtype or base
|
|
-- type, but there is one case in which the setting is non-obvious,
|
|
-- namely the case of an unsigned subtype of a signed type from which
|
|
-- a further subtype is obtained using variable bounds. This further
|
|
-- subtype is still unsigned, but this cannot be determined by looking
|
|
-- at its bounds or the bounds of the corresponding base type.
|
|
|
|
-- Is_Valued_Procedure (Flag127)
|
|
-- Present in procedure entities. Set if an Import_Valued_Procedure
|
|
-- or Export_Valued_Procedure pragma applies to the procedure entity.
|
|
|
|
-- Is_Visible_Child_Unit (Flag116)
|
|
-- Present in compilation units that are child units. Once compiled,
|
|
-- child units remain chained to the entities in the parent unit, and
|
|
-- a separate flag must be used to indicate whether the names are
|
|
-- visible by selected notation, or not.
|
|
|
|
-- Is_VMS_Exception (Flag133)
|
|
-- Present in all entities. Set only for exception entities where the
|
|
-- exception was specified in an Import_Exception or Export_Exception
|
|
-- pragma with the VMS option for Form. See description of these pragmas
|
|
-- for details. This flag can only be set in OpenVMS versions of GNAT.
|
|
|
|
-- Is_Volatile (Flag16)
|
|
-- Present in all type entities, and also in constants, components and
|
|
-- variables. Set if a pragma Volatile applies to the entity. Also set
|
|
-- if pragma Shared or pragma Atomic applies to entity. In the case of
|
|
-- private or incomplete types, this flag is set in both the private
|
|
-- and full view.
|
|
|
|
-- Is_Wrapper_Package (synthesized)
|
|
-- Present in package entities. Indicates that the package has been
|
|
-- created as a wrapper for a subprogram instantiation.
|
|
|
|
-- Last_Entity (Node20)
|
|
-- Present in all entities which act as scopes to which a list of
|
|
-- associated entities is attached (blocks, class subtypes and types,
|
|
-- entries, functions, loops, packages, procedures, protected objects,
|
|
-- record types and subtypes, private types, task types and subtypes).
|
|
-- Points to a the last entry in the list of associated entities chained
|
|
-- through the Next_Entity field. Empty if no entities are chained.
|
|
|
|
-- Lit_Indexes (Node15)
|
|
-- Present in enumeration types and subtypes. Non-empty only for the
|
|
-- case of an enumeration root type, where it contains the entity for
|
|
-- the generated indexes entity. See unit Exp_Imgv for full details of
|
|
-- the nature and use of this entity for implkementing the Image and
|
|
-- Value attributes for the enumeration type in question.
|
|
--
|
|
-- Lit_Strings (Node16)
|
|
-- Present in enumeration types and subtypes. Non-empty only for the
|
|
-- case of an enumeration root type, where it contains the entity for
|
|
-- the literals string entity. See unit Exp_Imgv for full details of
|
|
-- the nature and use of this entity for implementing the Image and
|
|
-- Value attributes for the enumeration type in question.
|
|
|
|
-- Machine_Radix_10 (Flag84)
|
|
-- Present in decimal types and subtypes, set if the Machine_Radix
|
|
-- is 10, as the result of the specification of a machine radix
|
|
-- representation clause. Note that it is possible for this flag
|
|
-- to be set without having Has_Machine_Radix_Clause True. This
|
|
-- happens when a type is derived from a type with a clause present.
|
|
|
|
-- Master_Id (Node17)
|
|
-- Present in access types and subtypes. Empty unless Has_Task is
|
|
-- set for the designated type, in which case it points to the entity
|
|
-- for the Master_Id for the access type master.
|
|
|
|
-- Materialize_Entity (Flag168)
|
|
-- Present in all entities. Set only for constant or renamed entities
|
|
-- which should be materialized for debugging purposes. In the case of
|
|
-- a constant, a memory location should be allocated containing the
|
|
-- value. In the case of a renaming, a memory location containing the
|
|
-- renamed address should be allocated.
|
|
|
|
-- Mechanism (Uint8) (returned as Mechanism_Type)
|
|
-- Present in functions and non-generic formal parameters. Indicates
|
|
-- the mechanism to be used for the function return or for the formal
|
|
-- parameter. See separate section on passing mechanisms. This field
|
|
-- is also set (to the default value of zero) in a subprogram body
|
|
-- entity but not used in this context.
|
|
|
|
-- Modulus (Uint17) [base type only]
|
|
-- Present in modular types. Contains the modulus. For the binary
|
|
-- case, this will be a power of 2, but if Non_Binary_Modulus is
|
|
-- set, then it will not be a power of 2.
|
|
|
|
-- Needs_Debug_Info (Flag147)
|
|
-- Present in all entities. Set if the entity requires debugging
|
|
-- information to be generated. This is true of all entities that
|
|
-- have Comes_From_Source set, and also transitively for entities
|
|
-- associated with such components (e.g. their types). It is true
|
|
-- for all entities in Debug_Generated_Code mode (-gnatD switch).
|
|
|
|
-- Needs_No_Actuals (Flag22)
|
|
-- Present in callable entities (subprograms, entries, access to
|
|
-- subprograms) which can be called without actuals because all of
|
|
-- their formals (if any) have default values. This flag simplifies the
|
|
-- resolution of the syntactic ambiguity involving a call to these
|
|
-- entities when the return type is an array type, and a call can be
|
|
-- interpreted as an indexing of the result of the call. It is also
|
|
-- used to resolve various cases of entry calls.
|
|
|
|
-- Not_Source_Assigned (Flag115)
|
|
-- Present in all entities, but relevant only for variables and
|
|
-- parameters. This flag is set if the object is never assigned a
|
|
-- value in user code and was not fully initialized at declaration
|
|
-- time. Note however, that an access variable is not considered
|
|
-- fully initialized in this sense.
|
|
--
|
|
-- This flag is only for the purposes of issuing warnings, it must not
|
|
-- be used by the code generator to indicate that the variable is in
|
|
-- fact a constant, since some assignments in generated code do not
|
|
-- count (for example, the call to an init_proc to assign some but
|
|
-- not all of the fields in a patially initialized record). The code
|
|
-- generator should instead use the flag Is_True_Constant.
|
|
--
|
|
-- In variables and out parameters, if this flag is set after full
|
|
-- processing of the corresponding declarative unit, it indicates that
|
|
-- the variable or parameter was never set, and a warning message can
|
|
-- be issued.
|
|
--
|
|
-- Note: this flag is initially set, and then cleared on encountering
|
|
-- any construct that might conceivably legitimately set the value.
|
|
-- Thus during the analysis of a declarative region and its associated
|
|
-- statement sequence, the meaning of the flag is "not assigned yet",
|
|
-- and once this analysis is complete the flag means "never assigned".
|
|
|
|
-- Note: for variables appearing in package declarations, this flag
|
|
-- is never set. That is because there is no way to tell if some
|
|
-- client modifies the variable (or in the case of variables in the
|
|
-- private part, if some child unit modifies the variables).
|
|
|
|
-- Note: in the case of renamed objects, the flag must be set in the
|
|
-- ultimate renamed object. Clients noting a possible modification
|
|
-- should use the Note_Possible_Modification procedure in Sem_Util
|
|
-- rather than Set_Not_Source_Assigned precisely to deal properly with
|
|
-- the renaming possibility.
|
|
|
|
-- Next_Component (synthesized)
|
|
-- Applies to record components. Returns the next component by
|
|
-- following the chain of declared entities until one is found which
|
|
-- corresponds to a component (Ekind is E_Component). Any internal types
|
|
-- generated from the subtype indications of the record components are
|
|
-- skipped. Returns Empty if no more components.
|
|
|
|
-- Next_Discriminant (synthesized)
|
|
-- Applies to discriminants returned by First/Next_Discriminant.
|
|
-- Returns the next language-defined (ie: perhaps non-girder)
|
|
-- discriminant by following the chain of declared entities as long as
|
|
-- the kind of the entity corresponds to a discriminant. Note that the
|
|
-- discriminants might be the only components of the record.
|
|
-- Returns Empty if there are no more.
|
|
|
|
-- Next_Entity (Node2)
|
|
-- Present in all entities. The entities of a scope are chained, with
|
|
-- the head of the list being in the First_Entity field of the scope
|
|
-- entity. All entities use the Next_Entity field as a forward pointer
|
|
-- for this list, with Empty indicating the end of the list. Since this
|
|
-- field is in the base part of the entity, the access routines for this
|
|
-- field are in Sinfo.
|
|
|
|
-- Next_Formal (synthesized)
|
|
-- Applies to the entity for a formal parameter. Returns the next
|
|
-- formal parameter of the subprogram or subprogram type. Returns
|
|
-- Empty if there are no more formals.
|
|
|
|
-- Next_Formal_With_Extras (synthesized)
|
|
-- Applies to the entity for a formal parameter. Returns the next
|
|
-- formal parameter of the subprogram or subprogram type. Returns
|
|
-- Empty if there are no more formals. The list returned includes
|
|
-- all the extra formals (see description of Extra_Formal field)
|
|
|
|
-- Next_Girder_Discriminant (synthesized)
|
|
-- Applies to discriminants. Set only for a discriminant returned by
|
|
-- a call to First/Next_Girder_Discriminant. Returns next girder
|
|
-- discriminant, if there are more (see complete description in
|
|
-- First_Girder_Discriminant), or Empty if there are no more.
|
|
|
|
-- Next_Index (synthesized)
|
|
-- Applies to array types and subtypes and to string types and
|
|
-- subtypes. Yields the next index. The first index is obtained by
|
|
-- using the First_Index attribute, and then subsequent indexes are
|
|
-- obtained by applying Next_Index to the previous index. Empty is
|
|
-- returned to indicate that there are no more indexes. Note that
|
|
-- unlike most attributes in this package, Next_Index applies to
|
|
-- nodes for the indexes, not to entities.
|
|
|
|
-- Next_Inlined_Subprogram (Node12)
|
|
-- Present in subprograms. Used to chain inlined subprograms used in
|
|
-- the current compilation, in the order in which they must be compiled
|
|
-- by Gigi to insure that all inlinings are performed.
|
|
|
|
-- Next_Literal (synthesized)
|
|
-- Applies to enumeration literals, returns the next literal, or
|
|
-- Empty if applied to the last literal. This is actually a synonym
|
|
-- for Next, but its use is preferred in this context.
|
|
|
|
-- Non_Binary_Modulus (Flag58) [base type only]
|
|
-- Present in modular integer types. Set if the modulus for the type
|
|
-- is other than a power of 2.
|
|
|
|
-- Nonzero_Is_True (Flag162) [base type only]
|
|
-- Present in enumeration types. True if any non-zero value is to be
|
|
-- interpreted as true. Currently this is set true for derived Boolean
|
|
-- types which have a convention of C, C++ or Fortran.
|
|
|
|
-- No_Pool_Assigned (Flag131) [root type only]
|
|
-- Present in access types. Set if a storage size clause applies to
|
|
-- the variable with a compile time known value of zero. This flag is
|
|
-- used to generate warnings if any attempt is made to allocate an
|
|
-- instance of such an access type. This is set only in the root
|
|
-- type, since derived types must have the same pool.
|
|
|
|
-- No_Return (Flag113)
|
|
-- Present in procedure and generic procedure entries. Indicates that
|
|
-- a pragma No_Return applies to the procedure.
|
|
|
|
-- Normalized_First_Bit (Uint8)
|
|
-- Present in components and discriminants. Indicates the normalized
|
|
-- value of First_Bit for the component, i.e. the offset within the
|
|
-- lowest addressed storage unit containing part or all of the field.
|
|
|
|
-- Normalized_Position (Uint9)
|
|
-- Present in components and discriminants. Indicates the normalized
|
|
-- value of Position for the component, i.e. the offset in storage
|
|
-- units from the start of the record to the lowest addressed storage
|
|
-- unit containing part or all of the field.
|
|
|
|
-- Normalized_Position_Max (Uint10)
|
|
-- Present in components and discriminants. For almost all cases, this
|
|
-- is the same as Normalized_Position. The one exception is for the case
|
|
-- of a discriminated record containing one or more arrays whose length
|
|
-- depends on discriminants. In this case, the Normalized_Position_Max
|
|
-- field represents the maximum possible value of Normalized_Position
|
|
-- assuming min/max values for discriminant subscripts in all fields.
|
|
-- This is used by Layout in front end layout mode to properly computed
|
|
-- the maximum size such records (needed for allocation purposes when
|
|
-- there are default discriminants, and also for the 'Size value).
|
|
|
|
-- Number_Dimensions (synthesized)
|
|
-- Applies to array types and subtypes. Returns the number of dimensions
|
|
-- of the array type or subtype as a value of type Pos.
|
|
|
|
-- Number_Discriminants (synthesized)
|
|
-- Applies to all types with discriminants. Yields the number of
|
|
-- discriminants as a value of type Pos.
|
|
|
|
-- Number_Entries (synthesized)
|
|
-- Applies to concurrent types. Returns the number of entries that are
|
|
-- declared within the task or protected definition for the type.
|
|
|
|
-- Number_Formals (synthesized)
|
|
-- Applies to subprograms and subprogram types. Yields the number of
|
|
-- formals as a value of type Pos.
|
|
|
|
-- Original_Array_Type (Node21)
|
|
-- Present in modular types and array types and subtypes. Set only
|
|
-- if the Is_Packed_Array_Type flag is set, indicating that the type
|
|
-- is the implementation type for a packed array, and in this case it
|
|
-- points to the original array type for which this is the packed
|
|
-- array implementation type.
|
|
|
|
-- Object_Ref (Node17)
|
|
-- Present in protected bodies. This is an implicit prival for the
|
|
-- Protection object associated with a protected object. See Prival
|
|
-- for further details on the use of privals.
|
|
|
|
-- Original_Record_Component (Node22)
|
|
-- Present in components, including discriminants. The usage depends
|
|
-- on whether the record is a base type and whether it is tagged.
|
|
--
|
|
-- In base tagged types:
|
|
-- When the component is inherited in a record extension, it points
|
|
-- to the original component (the entity of the ancestor component
|
|
-- which is not itself inherited) otherwise it points to itself.
|
|
-- Gigi uses this attribute to implement the automatic dereference in
|
|
-- the extension and to apply the transformation:
|
|
--
|
|
-- Rec_Ext.Comp -> Rec_Ext.Parent. ... .Parent.Comp
|
|
--
|
|
-- In base non-tagged types:
|
|
-- Always points to itself except for non-girder discriminants, where
|
|
-- it points to the girder discriminant it renames.
|
|
--
|
|
-- In subtypes (tagged and untagged):
|
|
-- Points to the component in the base type.
|
|
|
|
-- Packed_Array_Type (Node23)
|
|
-- Present in array types and subtypes, including the string literal
|
|
-- subtype case, if the corresponding type is packed (either bit packed
|
|
-- or packed to eliminate holes in non-contiguous enumeration type
|
|
-- index types). References the type used to represent the packed array,
|
|
-- which is either a modular type for short static arrays, or an
|
|
-- array of System.Unsigned. Note that in some situations (internal
|
|
-- types, and references to fields of variant records), it is not
|
|
-- always possible to construct this type in advance of its use. If
|
|
-- Packed_Array_Type is empty, then the necessary type is declared
|
|
-- on the fly for each reference to the array.
|
|
|
|
-- Parameter_Mode (synthesized)
|
|
-- Applies to formal parameter entities. This is a synonym for Ekind,
|
|
-- used when obtaining the formal kind of a formal parameter (the result
|
|
-- is one of E_[In/Out/In_Out]_Paramter)
|
|
|
|
-- Parent_Subtype (Node19)
|
|
-- Present in E_Record_Type. Points to the subtype to use for a
|
|
-- field that references the parent record. This is used by Gigi to
|
|
-- construct such a field.
|
|
|
|
-- Primitive_Operations (Elist15)
|
|
-- Present in tagged record types and subtypes and in tagged private
|
|
-- types. Points to an element list of entities for primitive operations
|
|
-- for the tagged type. Not present (and not set) in untagged types (it
|
|
-- is an error to reference the primitive operations field of a type
|
|
-- that is not tagged).
|
|
|
|
-- Private_Dependents (Elist18)
|
|
-- Present in private (sub)types. Records the subtypes of the
|
|
-- private type, derivations from it, and records and arrays
|
|
-- with components dependent on the type.
|
|
--
|
|
-- The subtypes are traversed when installing and deinstalling
|
|
-- (the full view of) a private type in order to ensure correct
|
|
-- view of the subtypes.
|
|
--
|
|
-- Used in similar fashion for incomplete types: holds list of subtypes
|
|
-- of these incomplete types that have discriminant constraints. The
|
|
-- full views of these subtypes are constructed when the full view of
|
|
-- the incomplete type is processed.
|
|
|
|
-- In addition, if the incomplete type is the designated type in an
|
|
-- access definition for an access parameter, the operation may be
|
|
-- a dispatching primitive operation, which is only known when the full
|
|
-- declaration of the type is seen. Subprograms that have such an
|
|
-- access parameter are also placed in the list of private_dependents.
|
|
|
|
-- Prival (Node17)
|
|
-- Present in components. Used for representing private declarations
|
|
-- of protected objects (private formal: by analogy to Discriminal_Link).
|
|
-- Empty unless the synthesized Is_Protected_Private attribute is
|
|
-- true. The entity used as a formal parameter that corresponds to
|
|
-- the to the private declaration in protected operations. See
|
|
-- "Private data in protected objects" for details.
|
|
|
|
-- Privals_Chain (Elist23)
|
|
-- Present in protected operations (subprograms and entries). Links
|
|
-- all occurrences of the Privals in the body of the operation, in
|
|
-- order to patch their types at the end of their expansion. See
|
|
-- "Private data in protected objects" for details.
|
|
|
|
-- Private_View (Node22)
|
|
-- For each private type, three entities are allocated, the private view,
|
|
-- the full view, and the shadow entity. The shadow entity contains a
|
|
-- copy of the private view and is used for restoring the proper private
|
|
-- view after a region in which the full view is visible (and is copied
|
|
-- into the entity normally used for the private view during this period
|
|
-- of visibility). The Private_View field is self-referential when the
|
|
-- private view lives in its normal entity, but in the copy that is made
|
|
-- in the shadow entity, it points to the proper location in which to
|
|
-- restore the private view saved in the shadow.
|
|
|
|
-- Protected_Formal (Node22)
|
|
-- Present in formal parameters (in, in out and out parameters). Used
|
|
-- only for formals of protected operations. References corresponding
|
|
-- formal parameter in the unprotected version of the operation that
|
|
-- is created during expansion.
|
|
|
|
-- Protected_Body_Subprogram (Node11)
|
|
-- Present in protected operations. References the entity for the
|
|
-- subprogram which implements the body of the operation.
|
|
|
|
-- Protected_Operation (Node23)
|
|
-- Present in components. Used for representing private declarations
|
|
-- of protected objects. Empty unless the synthesized attribute
|
|
-- Is_Protected_Private is True. This is the entity corresponding
|
|
-- to the body of the protected operation currently being analyzed,
|
|
-- and which will eventually use the current Prival associated with
|
|
-- this component to refer to the renaming of a private object
|
|
-- component. As soon as the expander generates this renaming, this
|
|
-- attribute is changed to refer to the next protected subprogram.
|
|
-- See "Private data in protected objects" for details.
|
|
|
|
-- Reachable (Flag49)
|
|
-- Present in labels. The flag is set over the range of statements in
|
|
-- which a goto to that label is legal.
|
|
|
|
-- Referenced (Flag156)
|
|
-- Present in all entities, set if the entity is referenced.
|
|
|
|
-- Referenced_Object (Node10)
|
|
-- Present in all type entities. Set non-Empty only for type entities
|
|
-- constructed for unconstrained objects, or objects that depend on
|
|
-- discriminants. Points to the expression from which the actual
|
|
-- subtype of the object can be evaluated.
|
|
|
|
-- Register_Exception_Call (Node20)
|
|
-- Present in exception entities. When an exception is declared,
|
|
-- a call is expanded to Register_Exception. This field points to
|
|
-- the expanded N_Procedure_Call_Statement node for this call. It
|
|
-- is used for Import/Export_Exception processing to modify the
|
|
-- register call to make appropriate entries in the special tables
|
|
-- used for handling these pragmas at runtime.
|
|
|
|
-- Related_Array_Object (Node19)
|
|
-- Present in array types and subtypes. Used only for the base type
|
|
-- and subtype created for an anonymous array object. Set to point
|
|
-- to the entity of the corresponding array object. Currently used
|
|
-- only for type-related error messages.
|
|
|
|
-- Related_Instance (Node15)
|
|
-- Present in the wrapper packages created for subprogram instances.
|
|
-- The internal subprogram that implements the instance is inside the
|
|
-- wrapper package, but for debugging purposes its external symbol
|
|
-- must correspond to the name and scope of the related instance.
|
|
|
|
-- Renamed_Entity (Node18)
|
|
-- Present in exceptions, packages and generic units that are defined
|
|
-- by a renaming declaration. Denotes the renamed entity, or transit-
|
|
-- itively the ultimate renamed entity if there is a chain of renaming
|
|
-- declarations.
|
|
|
|
-- Renamed_Object (Node18)
|
|
-- Present in all objects (constants, variables, components, formal
|
|
-- parameters, generic formal parameters, and loop parameters. Set
|
|
-- non-Empty if the object was declared by a renaming declaration, in
|
|
-- which case it references the tree node for the name of the renamed
|
|
-- object. This is only possible for the variable and constant cases.
|
|
-- For formal parameters, this field is used in the course of inline
|
|
-- expansion, to map the formals of a subprogram into the corresponding
|
|
-- actuals. The field is Empty otherwise.
|
|
|
|
-- Renaming_Map (Uint9)
|
|
-- Present in generic subprograms, generic packages, and their
|
|
-- instances. Also present in the instances of the corresponding
|
|
-- bodies. Denotes the renaming map (generic entities => instance
|
|
-- entities) used to construct the instance by givin an index into
|
|
-- the tables used to represent these maps. See Sem_Ch12 for further
|
|
-- details. The maps for package instances are also used when the
|
|
-- instance is the actual corresponding to a formal package.
|
|
|
|
-- Return_Present (Flag54)
|
|
-- Present in function and generic function entities. Set if the
|
|
-- function contains a return statement (used for error checking).
|
|
-- This flag can also be set in procedure and generic procedure
|
|
-- entities (for convenience in setting it), but is only tested
|
|
-- for the function case.
|
|
|
|
-- Returns_By_Ref (Flag90)
|
|
-- Present in function entities, to indicate that the function
|
|
-- returns the result by reference, either because its return typ is a
|
|
-- by-reference-type or because it uses explicitly the secondary stack.
|
|
|
|
-- Reverse_Bit_Order (Flag164) [base type only]
|
|
-- Present in all record type entities. Set if a valid pragma an
|
|
-- attribute represention clause for Bit_Order has reversed the order
|
|
-- of bits from the default value. When this flag is set, a component
|
|
-- clause must specify a set of bits entirely contained in a single
|
|
-- storage unit.
|
|
|
|
-- RM_Size (Uint13)
|
|
-- Present in all type and subtype entities. Contains the value of
|
|
-- type'Size as defined in the RM. See also the Esize field and
|
|
-- and the description on "Handling of Type'Size Values". A value
|
|
-- of zero for in this field for a non-discrete type means that
|
|
-- the front end has not yet determined the size value. For the
|
|
-- case of a discrete type, this field is always set by the front
|
|
-- end and zero is a legitimate value for a type with one value.
|
|
|
|
-- Root_Type (synthesized)
|
|
-- Applies to all type entities. For class-wide types, return the root
|
|
-- type of the class covered by the CW type, otherwise returns the
|
|
-- ultimate derivation ancestor of the given type. This function
|
|
-- preserves the view, i.e. the Root_Type of a partial view is the
|
|
-- partial view of the ulimate ancestor, the Root_Type of a full view
|
|
-- is the full view of the ultimate ancestor. Note that this function
|
|
-- does not correspond exactly to the use of root type in the RM, since
|
|
-- in the RM root type applies to a class of types, not to a type.
|
|
|
|
-- Scalar_Range (Node20)
|
|
-- Present in all scalar types (including modular types, where the
|
|
-- bounds are 0 .. modulus - 1). References a node in the tree that
|
|
-- contains the bounds for the range. Note that this information
|
|
-- could be obtained by rummaging around the tree, but it is more
|
|
-- convenient to have it immediately at hand in the entity. The
|
|
-- contents of Scalar_Range can either be an N_Subtype_Indication
|
|
-- node (with a constraint), or a Range node, but not a simple
|
|
-- subtype reference (a subtype is converted into a range).
|
|
|
|
-- Scale_Value (Uint15)
|
|
-- Present in decimal fixed-point types and subtypes. Contains the scale
|
|
-- for the type (i.e. the value of type'Scale = the number of decimal
|
|
-- digits after the decimal point).
|
|
|
|
-- Scope (Node3)
|
|
-- Present in all entities. Points to the entity for the scope (block,
|
|
-- loop, subprogram, package etc.) in which the entity is declared.
|
|
-- Since this field is in the base part of the entity node, the access
|
|
-- routines for this field are in Sinfo.
|
|
|
|
-- Scope_Depth (synth)
|
|
-- Applies to program units, blocks, concurrent types and entries,
|
|
-- and also to record types, i.e. to any entity that can appear on
|
|
-- the scope stack. Yields the scope depth value, which for those
|
|
-- entities other than records is simply the scope depth value,
|
|
-- for record entities, it is the Scope_Depth of the record scope.
|
|
|
|
-- Scope_Depth_Value (Uint22)
|
|
-- Present in program units, blocks, concurrent types and entries.
|
|
-- Indicates the number of scopes that statically enclose the
|
|
-- declaration of the unit or type. Library units have a depth of zero.
|
|
-- Note that record types can act as scopes but do NOT have this field
|
|
-- set (see Scope_Depth above)
|
|
|
|
-- Scope_Depth_Set (synthesized)
|
|
-- Applies to a special predicate function that returns a Boolean value
|
|
-- indicating whether or not the Scope_Depth field has been set. It
|
|
-- is needed, since returns an invalid value in this case!
|
|
|
|
-- Sec_Stack_Needed_For_Return (Flag167)
|
|
-- Present in scope entities (blocks,functions, procedures, tasks,
|
|
-- entries). Set to True when secondary stack is used to hold
|
|
-- the returned value of a function and thus should not be
|
|
-- released on scope exit.
|
|
|
|
-- Shadow_Entities (List14)
|
|
-- Present in package and generic package entities. Points to a list
|
|
-- of entities that correspond to private types. For each private type
|
|
-- a shadow entity is created that holds a copy of the private view.
|
|
-- In regions of the program where the full views of these private
|
|
-- entities are visible, the full view is copied into the entity that
|
|
-- is normally used to hold the private view, but the shadow entity
|
|
-- copy is unchanged. The shadow entities are then used to restore the
|
|
-- original private views at the end of the region. This list is a
|
|
-- standard format list (i.e. First (Shadow_Entities) is the first
|
|
-- entry and subsequent entries are obtained using Next.
|
|
|
|
-- Shared_Var_Assign_Proc (Node22)
|
|
-- Present in variables. Set non-Empty only if Is_Shared_Passive is
|
|
-- set, in which case this is the entity for the shared memory assign
|
|
-- routine. See Exp_Smem for full details.
|
|
|
|
-- Shared_Var_Read_Proc (Node15)
|
|
-- Present in variables. Set non-Empty only if Is_Shared_Passive is
|
|
-- set, in which case this is the entity for the shared memory read
|
|
-- routine. See Exp_Smem for full details.
|
|
|
|
-- Size_Check_Code (Node9)
|
|
-- Present in constants and variables. Normally Empty. Set if code is
|
|
-- generated to check the size of the variable. This field is used to
|
|
-- suppress this code if a subsequent address clause is encountered.
|
|
|
|
-- Size_Clause (synthesized)
|
|
-- Applies to all entities. If a size clause is present in the rep
|
|
-- item chain for an entity then the attribute definition clause node
|
|
-- for the size clause is returned. Otherwise Size_Clause returns Empty
|
|
-- if no item is present. Usually this is only meaningful if the flag
|
|
-- Has_Size_Clause is set. This is because when the representation item
|
|
-- chain is copied for a derived type, it can inherit a size clause that
|
|
-- is not applicable to the entity.
|
|
|
|
-- Size_Depends_On_Discriminant (Flag177)
|
|
-- Present in all entities for types and subtypes. Indicates that the
|
|
-- size of the type depends on the value of one or more discriminants.
|
|
-- Currently, this flag is only set in front end layout mode for arrays
|
|
-- which have one or more bounds depending on a discriminant value.
|
|
|
|
-- Size_Known_At_Compile_Time (Flag92)
|
|
-- Present in all entities for types and subtypes. Indicates that the
|
|
-- size of objects of the type is known at compile time. This flag is
|
|
-- used to optimize some generated code sequences, and also to enable
|
|
-- some error checks (e.g. disallowing component clauses on variable
|
|
-- length objects. It is set conservatively (i.e. if it is True, the
|
|
-- size is certainly known at compile time, if it is False, then the
|
|
-- size may or may not be known at compile time, but the code will
|
|
-- assume that it is not known).
|
|
|
|
-- Small_Value (Ureal21)
|
|
-- Present in fixed point types. Points to the universal real for the
|
|
-- Small of the type, either as given in a representation clause, or
|
|
-- as computed (as a power of two) by the compiler.
|
|
|
|
-- Spec_Entity (Node19)
|
|
-- Present in package body entities. Points to corresponding package
|
|
-- spec entity. Also present in subprogram body parameters in the
|
|
-- case where there is a separate spec, where this field references
|
|
-- the corresponding parameter entities in the spec.
|
|
|
|
-- Storage_Size_Variable (Node15) [implementation base type only]
|
|
-- Present in access types and task type entities. This flag is set
|
|
-- if a valid and effective pragma Storage_Size applies to the base
|
|
-- type. Points to the entity for a variable that is created to
|
|
-- hold the value given in a Storage_Size pragma for an access
|
|
-- collection or a task type. Note that in the access type case,
|
|
-- this field is present only in the root type (since derived types
|
|
-- share the same storage pool).
|
|
|
|
-- Strict_Alignment (Flag145) [implementation base type only]
|
|
-- Present in all type entities. Indicates that some containing part
|
|
-- is either aliased or tagged. This prohibits packing the object
|
|
-- tighter than its natural size and alignment.
|
|
|
|
-- String_Literal_Length (Uint16)
|
|
-- Present in string literal subtypes (which are created to correspond
|
|
-- to string literals in the program). Contains the length of the string
|
|
-- literal.
|
|
|
|
-- String_Literal_Low_Bound (Node15)
|
|
-- Present in string literal subtypes (which are created to correspond
|
|
-- to string literals in the program). Contains an expression whose
|
|
-- value represents the low bound of the literal. This is a copy of
|
|
-- the low bound of the applicable index constraint if there is one,
|
|
-- or a copy of the low bound of the index base type if not.
|
|
|
|
-- Suppress_Access_Checks (Flag31)
|
|
-- Present in all entities. Set if access checks associated with this
|
|
-- entity are to be suppressed (see separate section on "Handling of
|
|
-- Check Suppression")
|
|
|
|
-- Suppress_Accessibility_Checks (Flag32)
|
|
-- Present in all entities. Set if accessibility checks associated with
|
|
-- this entity are to be suppressed (see separate section on "Handling
|
|
-- of Check Suppression")
|
|
|
|
-- Suppress_Discriminant_Checks (Flag33)
|
|
-- Present in all entities. Set if discriminant checks associated with
|
|
-- this entity are to be suppressed (see separate section on "Handling
|
|
-- of Check Suppression")
|
|
|
|
-- Suppress_Division_Checks (Flag34)
|
|
-- Present in all entities. Set if division checks associated with
|
|
-- this entity are to be suppressed (see separate section on "Handling
|
|
-- of Check Suppression")
|
|
|
|
-- Suppress_Elaboration_Checks (Flag35)
|
|
-- Present in all entities. Set if elaboration checks associated with
|
|
-- this entity are to be suppressed (see separate section on "Handling
|
|
-- of Check Suppression")
|
|
|
|
-- Suppress_Elaboration_Warnings (Flag148)
|
|
-- Present in all entities. Set if a pragma Suppress Elaboration_Checks
|
|
-- is applied specifically to the entity. If set on a subprogram, all
|
|
-- elaboration warnings for calls to the subprogram are suppressed. If
|
|
-- set on a package, then all elaboration warnings for calls to any
|
|
-- subprograms in the package are suppressed.
|
|
|
|
-- Suppress_Index_Checks (Flag36)
|
|
-- Present in all entities. Set if index checks associated with this
|
|
-- entity are to be suppressed (see separate section on "Handling of
|
|
-- Check Suppression")
|
|
|
|
-- Suppress_Init_Proc (Flag105) [base type only]
|
|
-- Present in all type entities. Set to suppress the generation of
|
|
-- initialization procedures where they are known to be not needed.
|
|
-- For example, the enumeration image table entity uses this flag.
|
|
|
|
-- Suppress_Length_Checks (Flag37)
|
|
-- Present in all entities. Set if length checks associated with this
|
|
-- entity are to be suppressed (see separate section on "Handling of
|
|
-- Check Suppression")
|
|
|
|
-- Suppress_Overflow_Checks (Flag38)
|
|
-- Present in all entities. Set if overflow checks associated with
|
|
-- this entity are to be suppressed (see separate section on "Handling
|
|
-- of Check Suppression")
|
|
|
|
-- Suppress_Range_Checks (Flag39)
|
|
-- Present in all entities. Set if range checks associated with this
|
|
-- entity are to be suppressed (see separate section on "Handling of
|
|
-- Check Suppression")
|
|
|
|
-- Suppress_Storage_Checks (Flag40)
|
|
-- Present in all entities. Set if storage checks associated with

|
-- this entity are to be suppressed (see separate section on "Handling
|
|
-- of Check Suppression")
|
|
|
|
-- Suppress_Style_Checks (Flag165)
|
|
-- Present in all entities. Suppresses any style checks specifically
|
|
-- associated with the given entity if set.
|
|
|
|
-- Suppress_Tag_Checks (Flag41)
|
|
-- Present in all entities. Set if tag checks associated with this
|
|
-- entity are to be suppressed (see separate section on "Handling of
|
|
-- Check Suppression")
|
|
|
|
-- Tag_Component (synthesized)
|
|
-- Applies to tagged record types, returns the entity for the _Tag
|
|
-- field in this record, which must be present.
|
|
|
|
-- Type_High_Bound (synthesized)
|
|
-- Applies to scalar types. Returns the tree node (Node_Id) that
|
|
-- contains the high bound of a scalar type. The returned value is a
|
|
-- literal for a base type, but may be an expression in the case of a
|
|
-- scalar type with dynamic bounds. Note that in the case of a fixed
|
|
-- point type, the high bound is in units of small, and is an integer.
|
|
|
|
-- Type_Low_Bound (synthesized)
|
|
-- Applies to scalar types. Returns the tree node (Node_Id) that
|
|
-- contains the low bound of a scalar type. The returned value is a
|
|
-- literal for a base type, but may be an expression in the case of a
|
|
-- scalar type with dynamic bounds. Note that in the case of a fixed
|
|
-- point type, the low bound is in units of small, and is an integer.
|
|
|
|
-- Underlying_Full_View (Node19)
|
|
-- Present in private subtypes that are the completion of other private
|
|
-- types, or in private types that are derived from private subtypes.
|
|
-- If the full view of a private type T is derived from another
|
|
-- private type with discriminants Td, the full view of T is also
|
|
-- private, and there is no way to attach to it a further full view that
|
|
-- would convey the structure of T to the back end. The Underlying_Full_
|
|
-- View is an attribute of the full view that is a subtype of Td with
|
|
-- the same constraint as the declaration for T. The declaration for this
|
|
-- subtype is built at the point of the declaration of T, either as a
|
|
-- completion, or as a subtype declaration where the base type is private
|
|
-- and has a private completion. If Td is already constrained, then its
|
|
-- full view can serve directly as the full view of T.
|
|
|
|
-- Underlying_Type (synthesized)
|
|
-- Applies to all entities. This is the identity function except in
|
|
-- the case where it is applied to an incomplete or private type,
|
|
-- in which case it is the underlying type of the type declared by
|
|
-- the completion, or Empty if the completion has not yet been
|
|
-- encountered and analyzed.
|
|
--
|
|
-- Note: the reason this attribute applies to all entities, and not
|
|
-- just types, is to legitimize code where Underlying_Type is applied
|
|
-- to an entity which may or may not be a type, with the intent that
|
|
-- if it is a type, its underlying type is taken.
|
|
|
|
-- Unset_Reference (Node16)
|
|
-- Present in variables and out parameters. This is normally Empty.
|
|
-- It is set to point to an identifier that represents a reference
|
|
-- to the entity before any value has been set. Only the first such
|
|
-- reference is identified. This field is used to generate a warning
|
|
-- message if necessary (see Sem_Warn.Check_Unset_Reference).
|
|
|
|
-- Uses_Sec_Stack (Flag95)
|
|
-- Present in scope entities (blocks,functions, procedures, tasks,
|
|
-- entries). Set to True when secondary stack is used in this scope and
|
|
-- must be released on exit unless Sec_Stack_Needed_For_Return is set.
|
|
|
|
-- Vax_Float (Flag151) [base type only]
|
|
-- Present in all type entities. Set only on the base type of float
|
|
-- types with Vax format. The particular format is determined by the
|
|
-- Digits_Value value which is 6,9,15 for F_Float, D_Float, G_Float.
|
|
|
|
-- Warnings_Off (Flag96)
|
|
-- Present in all entities. Set if a pragma Warnings (Off, entity-name)
|
|
-- is used to suppress warnings for a given entity. It is also used by
|
|
-- the compiler in some situations to kill spurious warnings.
|
|
|
|
------------------
|
|
-- Access Kinds --
|
|
------------------
|
|
|
|
-- The following three entity kinds are introduced by the corresponding
|
|
-- type definitions:
|
|
|
|
-- E_Access_Type, E_General_Access_Type, E_Anonymous_Access_Type.
|
|
|
|
-- In addition, we define the kind E_Allocator_Type to label
|
|
-- allocators. This is because special resolution rules apply to this
|
|
-- construct. Eventually the constructs are labeled with the access
|
|
-- type imposed by the context. Gigi should never see the type
|
|
-- E_Allocator.
|
|
|
|
-- Similarly, the type E_Access_Attribute_Type is used as the initial
|
|
-- kind associated with an access attribute. After resolution a specific
|
|
-- access type will be established as determined by the context.
|
|
|
|
-- Finally, the type Any_Access is used to label -null- during type
|
|
-- resolution. Any_Access is also replaced by the context type after
|
|
-- resolution.
|
|
|

--------------------------------
|
|
-- Classification of Entities --
|
|
--------------------------------
|
|
|
|
-- The classification of program entities which follows is a refinement of
|
|
-- the list given in RM 3.1(1). E.g., separate entities denote subtypes of
|
|
-- different type classes. Ada 95 entities include class wide types,
|
|
-- protected types, subprogram types, generalized access types, generic
|
|
-- formal derived types and generic formal packages.
|
|
|
|
-- The order chosen for these kinds allows us to classify related entities
|
|
-- so that they are contiguous. As a result, they do not appear in the
|
|
-- exact same order as their order of first appearance in the LRM (For
|
|
-- example, private types are listed before packages). The contiguity
|
|
-- allows us to define useful subtypes (see below) such as type entities,
|
|
-- overloaded entities, etc.
|
|
|
|
-- Each entity (explicitly or implicitly declared) has a kind, which is
|
|
-- a value of the following type:
|
|
|
|
type Entity_Kind is (
|
|
|
|
E_Void,
|
|
-- The initial Ekind value for a newly created entity. Also used as
|
|
-- the Ekind for Standard_Void_Type, a type entity in Standard used
|
|
-- as a dummy type for the return type of a procedure (the reason we
|
|
-- create this type is to share the circuits for performing overload
|
|
-- resolution on calls).

-- E_Void
|
|
-- Since E_Void is the initial Ekind value of an entity when it is first
|
|
-- created, one might expect that no attributes would be defined on such
|
|
-- an entity until its Ekind field is set. However, in practice, there
|
|
-- are many instances in which fields of an E_Void entity are set in the
|
|
-- code prior to setting the Ekind field. This is not well documented or
|
|
-- well controlled, and needs cleaning up later. Meanwhile, the access
|
|
-- procedures in the body of Einfo permit many, but not all, attributes
|
|
-- to be applied to an E_Void entity, precisely so that this kind of
|
|
-- pre-setting of attributes works. This is really a hole in the dynamic
|
|
-- type checking, since there is no assurance that the eventual Ekind
|
|
-- value will be appropriate for the attributes set, and the consequence
|
|
-- is that the dynamic type checking in the Einfo body is unnecessarily
|
|
-- weak. To be looked at systematically some time ???

-- Component_Alignment Control --
|
|
---------------------------------
|
|
|
|
-- There are four types of alignment possible for array and record
|
|
-- types, and a field in the type entities contains a value of the
|
|
-- following type indicating which alignment choice applies. For full
|
|
-- details of the meaning of these aligment types, see description
|
|
-- of the Component_Alignment pragma
|
|
|
|
type Component_Alignment_Kind is (
|
|
Calign_Default, -- default alignment
|
|
Calign_Component_Size, -- natural alignment for component size
|
|
Calign_Component_Size_4, -- natural for size <= 4, 4 for size >= 4
|
|
Calign_Storage_Unit); -- all components byte aligned
|
|
|
|
---------------
|
|
-- Iterators --
|
|
---------------
|
|
|
|
-- In addition to attributes that are stored as plain data, other
|
|
-- attributes are procedural, and require some small amount of
|
|
-- computation. Of course, from the point of view of a user of this
|
|
-- package, the distinction is not visible (even the field information
|
|
-- provided below should be disregarded, as it is subject to change
|
|
-- without notice!). A number of attributes appear as lists: lists of
|
|
-- formals, lists of actuals, of discriminants, etc. For these, pairs
|
|
-- of functions are defined, which take the form:
|
|
|
|
-- function First_Thing (E : Enclosing_Construct) return Thing;
|
|
-- function Next_Thing (T : Thing) return Thing;
|
|
|
|
-- The end of iteration is always signaled by a value of Empty, so that
|
|
-- loops over these chains invariably have the form:
|
|
|
|
-- This : Thing;
|
|
-- ...
|
|
-- This := First_Thing (E);
|
|
|
|
-- while Present (This) loop
|
|
-- Do_Something_With (This);
|
|
-- ...
|
|
-- This := Next_Thing (This);
|
|
-- end loop;
|

|
|
-- Handling of Check Suppression --
|
|
-----------------------------------
|
|
|
|
-- There are three ways that checks can be suppressed:
|
|
|
|
-- 1. At the command line level. Package Opt contains global Boolean
|
|
-- flags with names Suppress_Options.xxx_Checks, where xxx is the
|
|
-- name of one of the checks that can be suppressed (excluding
|
|
-- All_Checks, which is simply reflected by setting all the
|
|
-- individual flags)
|
|
|
|
-- 2. At the scope level. The body of Sem contains flags with names
|
|
-- Suppress.xxx_Checks which are set to indicate that the given
|
|
-- check is suppressed for the current scope. These flags are
|
|
-- saved in the scope stack on entry to a scope and restored on
|
|
-- exit from the scope.
|
|
|
|
-- 3. At the entity level. Each entity contains a set of flags named
|
|
-- Suppress_xxx_Checks which suppress the given check for that
|
|
-- particularly entity (of course not all flags are meaningful for
|
|
-- all entities).
|
|

-- reflect the semantic properties and allowed usage of discriminants in
|
|
-- the language.
|
|
|
|
-- In the case of discriminants used as bounds, the references are handled
|
|
-- directly, since special processing is needed in any case. However, there
|
|
-- are two circumstances in which discriminants are referenced in a quite
|
|
-- general manner, like any other variables:
|
|
|
|
-- In initialization expressions for records. Note that the expressions
|
|
-- used in Priority, Storage_Size, and Task_Info pragmas are effectively
|
|
-- in this category, since these pragmas are converted to initialized
|
|
-- record fields in the Corresponding_Record_Type.
|
|
|
|
-- In task and protected bodies, where the discriminant values may be
|
|
-- referenced freely within these bodies. Discriminants can also appear
|
|
-- in bounds of entry families and in defaults of operations.
|
|
|
|
-- In both these cases, the discriminants must be treated essentially as
|
|
-- objects. The following approach is used to simplify and minimize the
|
|
-- special processing that is required.
|
|
|
|
-- When a record type with discriminants is processed, the semantic
|
|
-- processing creates the entities for the discriminants. It also creates
|
|
-- an additional set of entities, called discriminals, one for each of
|
|
-- the discriminants, and the Discriminal field of the discriminant entity
|
|
-- points to this additional entity, which is initially created as an
|
|
-- uninitialized (E_Void) entity.
|
|
|
|
-- During expansion of expressions, any discriminant reference is replaced
|
|
-- by a reference to the corresponding discriminal. When the initialization
|
|
-- procedure for the record is created (there will always be one, since
|
|
-- discriminants are present, see Exp_Ch3 for further details), the
|
|
-- discriminals are used as the entities for the formal parameters of
|
|
-- this initialization procedure. The references to these discriminants
|
|
-- have already been replaced by references to these discriminals, which
|
|
-- are now the formal parameters corresponding to the required objects.
|
|
|
|
-- In the case of a task or protected body, the semantics similarly
|
|
-- creates a set of discriminals for the discriminants of the task or
|
|
-- protected type. When the procedure is created for the task body,
|
|
-- the parameter passed in is a reference to the task value type, which
|
|
-- contains the required discriminant values. The expander creates a
|
|
-- set of declarations of the form:
|
|
|
|
-- discriminal : constant dtype renames _Task.discriminant;
|
|
|
|
-- where discriminal is the discriminal entity referenced by the task
|
|
-- discriminant, and _Task is the task value passed in as the parameter.
|
|
-- Again, any references to discriminants in the task body have been
|
|
-- replaced by the discriminal reference, which is now an object that
|
|
-- contains the required value.
|
|
|
|
-- This approach for tasks means that two sets of discriminals are needed
|
|
-- for a task type, one for the initialization procedure, and one for the
|
|
-- task body. This works out nicely, since the semantics allocates one set
|
|
-- for the task itself, and one set for the corresponding record.
|
|
|
|
-- The one bit of trickiness arises in making sure that the right set of
|
|
-- discriminals is used at the right time. First the task definition is
|
|
-- processed. Any references to discriminants here are replaced by the
|
|
-- the corresponding *task* discriminals (the record type doesn't even
|
|
-- exist yet, since it is constructed as part of the expansion of the
|
|
-- task declaration, which happens after the semantic processing of the
|
|
-- task definition). The discriminants to be used for the corresponding
|
|
-- record are created at the same time as the other discriminals, and
|
|
-- held in the CR_Discriminant field of the discriminant. A use of the
|
|
-- discriminant in a bound for an entry family is replaced with the CR_
|
|
-- discriminant because it controls the bound of the entry queue array
|
|
-- which is a component of the corresponding record.
|
|
|
|
-- Just before the record initialization routine is constructed, the
|
|
-- expander exchanges the task and record discriminals. This has two
|
|
-- effects. First the generation of the record initialization routine
|
|
-- uses the discriminals that are now on the record, which is the set
|
|
-- that used to be on the task, which is what we want.
|
|
|
|
-- Second, a new set of (so far unused) discriminals is now on the task
|
|
-- discriminants, and it is this set that will be used for expanding the
|
|
-- task body, and also for the discriminal declarations at the start of
|
|
-- the task body.

|
|
-- Private data in protected objects --
|
|
---------------------------------------
|
|
|
|
-- Private object declarations in protected types pose problems
|
|
-- similar to those of discriminants. They are expanded to components
|
|
-- of a record which is passed as the parameter "_object" to expanded
|
|
-- forms of all protected operations. As with discriminants, timing
|
|
-- of this expansion is a problem. The sequence of statements for a
|
|
-- protected operation is expanded before the operation itself, so the
|
|
-- formal parameter for the record object containing the private data
|
|
-- does not exist when the references to that data are expanded.
|
|
|
|
-- For this reason, private data is handled in the same way as
|
|
-- discriminants, expanding references to private data in protected
|
|
-- operations (which appear as components) to placeholders which will
|
|
-- eventually become renamings of the private selected components
|
|
-- of the "_object" formal parameter. These placeholders are called
|
|
-- "privals", by analogy to the "discriminals" used to implement
|
|
-- discriminants. They are attached to the component declaration nodes
|
|
-- representing the private object declarations of the protected type.
|
|
|
|
-- As with discriminals, each protected subprogram needs a unique set
|
|
-- of privals, since they must refer to renamings of components of a
|
|
-- formal parameter of that operation. Entry bodies need another set,
|
|
-- which they all share and which is associated with renamings in the
|
|
-- Service_Entries procedure for the protected type (this is not yet
|
|
-- implemented???). This means that we must associate a new set of
|
|
-- privals (and discriminals) with the private declarations after
|
|
-- the body of a protected subprogram is processed.
|
|
|
|
-- The last complication is the presence of discriminants and discriminated
|
|
-- components. In the corresponding record, the components are constrained
|
|
-- by the discriminants of the record, but within each protected operation
|
|
-- they are constrained by the discriminants of the actual. The actual
|
|
-- subtypes of those components are constructed as for other unconstrained
|
|
-- formals, but the privals are created before the formal object is added
|
|
-- to the parameter list of the protected operation, so they carry the
|
|
-- nominal subtype of the original component. After the protected operation
|
|
-- is actually created (in the expansion of the protected body) we must
|
|
-- patch the types of each prival occurrence with the proper actual subtype
|
|
-- which is by now set. The Privals_Chain is used for this patching.

-- Type Representation Attribute Predicates --

-- These predicates test the setting of the indicated attribute. If
|
|
-- the value has been set, then Known is True, and Unknown is False.
|
|
-- If no value is set, then Known is False and Unknown is True. The
|
|
-- Known_Static predicate is true only if the value is set (Known)
|
|
-- and is set to a compile time known value. Note that in the case
|
|
-- of Alignment and Normalized_First_Bit, dynamic values are not
|
|
-- possible, so we do not need a separate Known_Static calls in
|
|
-- these cases. The not set (unknown values are as follows:
|
|
|
|
-- Alignment Uint_0 or No_Uint
|
|
-- Component_Size Uint_0 or No_Uint
|
|
-- Component_Bit_Offset No_Uint

|
|
-- we chose to use Uint_0 at first, and the change over will take time ???
|
|
-- This is particularly true for the RM_Size field, where a value of zero
|
|
-- is legitimate. We deal with this by a nasty kludge that knows that the
|
|
-- value is always known static for discrete types (and no other types can
