-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), and if an attempt is made to set them on
--- other than a subtype, they will instead be set on the corresponding base
--- type.
-
--- 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), and if an attempt is made
--- to set them on other than a subtype, they will instead be set on the
--- corresponding implementation base type.
-
--- 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) [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)
--- 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.
-
--- 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 occurrence 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 subtypes, and also in the special
--- enumeration table type created for enumeration type. References
--- the entity for the 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_Primitive_Operations (Flag120) [base type only]
--- Present in all type entities. Set if at least one primitive operation
--- is defined on the type. This flag is not yet properly set ???
-
--- 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)
--- 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)
--- 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)

-
--- 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)
--- 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.
-

--- i.e. Standard.Boolean and all types ultimately derived from it.
-
--- Is_By_Copy_Type (synthesized)
--- 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)
--- Present in all entities, true for character types and subtypes,
--- i.e. enumeration types that have at least one character literal.
-
--- Is_Child_Unit (Flag73)
--- Present in all entities. Set only for defining entities of program
--- units that are child units (but False for subunits).
-
--- Is_Class_Wide_Type (synthesized)
--- 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
--- declarations of the corresponding record type). See package Exp_Ch9
--- for further details.
-
--- Is_Concurrent_Type (synthesized)
--- Applies to all entities, true for task types and subtypes and
--- for protected types and subtypes.
-
--- Is_Constrained (Flag12)
--- Present in types or subtypes which may have index, discriminant
--- or range constraint (i.e. array types and subtypes, record types
--- and subtypes, string types and subtypes, and all numeric types).
--- Set if the type or subtype is constrained.
-
--- Is_Constr_Subt_For_U_Nominal (Flag80)
--- Present in all types and subtypes. Set true only for the constructed
--- subtype of an object whose nominal subtype is unconstrained. Note
--- 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.
-
--- Is_Controlled (Flag42) [base type only]

--- i.e. is either a descendant of Ada.Finalization.Controlled or of
--- Ada.Finalization.Limited_Controlled.
-

--- Present in all Formal_Kind entity. Marks the controlling parameters
--- of dispatching operations.
-

--- Present in all type entities, set only for tagged and untagged
--- record types to which the pragma CPP_Class has been applied.
-
--- Is_Decimal_Fixed_Point_Type (synthesized)
--- Applies to all type entities, true for decimal fixed point
--- types and subtypes.
-
--- Is_Derived_Type (synthesized)
--- Applies to all type entities. Determine if given entity is a
--- derived type
-
--- Is_Destructor (Flag77)
--- Present in function and procedure entities. Set if a pragma
--- CPP_Destructor applies to the subprogram.
-
--- Is_Discrete_Type (synthesized)
--- Applies to all entities, true for all discrete types and subtypes
-
--- Is_Discrete__Or_Fixed_Point_Type (synthesized)
--- Applies to all entities, true for all discrete types and subtypes
--- and all fixed-point types and subtypes.
-
--- Is_Discrim_SO_Function (Flag176)
--- Present in all entities, set only in E_Function entities that Layout
--- creates to compute discriminant-dependent dynamic size/offset values.

--- Present in all entities. Set true for procedures, functions,
--- generic procedures and generic functions if the corresponding
--- operation is dispatching.
-
--- Is_Dynamic_Scope (synthesized)
--- Applies to all Entities. Returns True if the entity is a dynamic
--- scope (i.e. a block, a subprogram a task_type or an entry).
-
--- Is_Elementary_Type (synthesized)
--- Applies to all entities, true for all elementary types and
--- subtypes. Either Is_Composite_Type or Is_Elementary_Type (but
--- not both) is true of any type.
-
--- Is_Eliminated (Flag124)
--- Present in type entities, subprogram entities, and object entities.
--- Indicates that the corresponding entity has been eliminated by use
--- of pragma Eliminate.
-
--- Is_Enumeration_Type (synthesized)
--- Present in all entities, true for enumeration types and subtypes
-
--- Is_Entry (synthesized)
--- Applies to all entities, True only for entry and entry family
--- entities and False for all other entity kinds.
-
--- Is_Entry_Formal (Flag52)
--- Present in all entities. Set only for entry formals (which can
--- only be in, in-out or out parameters). This flag is used to speed
--- 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
--- be exported in the OpenVMS and Java VM implementations of GNAT.
-
--- 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.
--- This may be the base type itself (e.g. for record declarations and
--- enumeration type declarations), or it may be the first subtype of
--- an anonymous base type (e.g. for integer type declarations or

--- 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).
-
--- 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.
-
--- 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.
-
--- 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.
-
--- 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]_Parameter)
-
--- 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)
--- 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).

- -- A task type, created by a task type declaration. An entity with this
- -- Ekind is also created to describe the anonymous type of a task that
- -- is created by a single task declaration.
-
- E_Task_Subtype,
- -- A subtype of a task type, created by a subtype declaration used to
- -- declare a subtype of a task type.
-
- E_Protected_Type,
- -- A protected type, created by a protected type declaration. An entity
- -- with this Ekind is also created to describe the anonymous type of
- -- a protected object created by a single protected declaration.
-
- E_Protected_Subtype,
- -- A subtype of a protected type, created by a subtype declaration used
- -- to declare a subtype of a protected type.
-
- -----------------
- -- Other Types --
- -----------------
-
- E_Exception_Type,
- -- The type of an exception created by an exception declaration
-
- E_Subprogram_Type,
- -- This is the designated type of an Access_To_Subprogram. Has type
- -- and signature like a subprogram entity, so can appear in calls,
- -- which are resolved like regular calls, except that such an entity
- -- is not overloadable.
-
- ---------------------------
- -- Overloadable Entities --
- ---------------------------
-
- E_Enumeration_Literal,
- -- An enumeration literal, created by the use of the literal in an
- -- enumeration type definition.
-
- E_Function,
- -- A function, created by a function declaration or a function body
- -- that acts as its own declaration.
-
- E_Operator,
- -- A predefined operator, appearing in Standard, or an implicitly
- -- defined concatenation operator created whenever an array is
- -- declared. We do not make normal derived operators explicit in
- -- the tree, but the concatenation operators are made explicit.
-
- E_Procedure,
- -- A procedure, created by a procedure declaration or a procedure
- -- body that acts as its own declaration.
-
- E_Entry,
- -- An entry, created by an entry declaration in a task or protected
- -- object.
-
- --------------------
- -- Other Entities --
- --------------------
-
- E_Entry_Family,
- -- An entry family, created by an entry family declaration in a
- -- task or protected type definition.
-
- E_Block,
- -- A block identifier, created by an explicit or implicit label on
- -- a block or declare statement.
-
- E_Entry_Index_Parameter,
- -- An entry index parameter created by an entry index specification
- -- for the body of a protected entry family.
-
- E_Exception,
- -- An exception created by an exception declaration. The exception
- -- itself uses E_Exception for the Ekind, the implicit type that is
- -- created to represent its type uses the Ekind E_Exception_Type.
-
- E_Generic_Function,
- -- A generic function. This is the entity for a generic function
- -- created by a generic subprogram declaration.
-
- E_Generic_Package,
- -- A generic package, this is the entity for a generic package created
- -- by a generic package declaration.
-
- E_Generic_Procedure,
- -- A generic function. This is the entity for a generic procedure
- -- created by a generic subprogram declaration.
-
- E_Label,
- -- The defining entity for a label. Note that this is created by the
- -- implicit label declaration, not the occurrence of the label itself,
- -- which is simply a direct name referring to the label.
-
- E_Loop,
- -- A loop identifier, created by an explicit or implicit label on a
- -- loop statement.
-
- E_Package,
- -- A package, created by a package declaration
-
- E_Package_Body,
- -- A package body. This entity serves only limited functions, since
- -- most semantic analysis uses the package entity (E_Package). However
- -- there are some attributes that are significant for the body entity.
- -- For example, collection of exception handlers.
-
- E_Protected_Object,
- -- A protected object, created by an object declaration that declares
- -- an object of a protected type.
-
- E_Protected_Body,
- -- A protected body. This entity serves almost no function, since all
- -- semantic analysis uses the protected entity (E_Protected_Type)
-
- E_Task_Body,
- -- A task body. This entity serves almost no function, since all
- -- semantic analysis uses the protected entity (E_Task_Type).
-
- E_Subprogram_Body
- -- A subprogram body. Used when a subprogram has a separate declaration
- -- to represent the entity for the body. This entity serves almost no
- -- function, since all semantic analysis uses the subprogram entity
- -- for the declaration (E_Function or E_Procedure).

-
- -- The above entities are arranged so that they can be conveniently
- -- grouped into subtype ranges. Note that for each of the xxx_KInd
- -- ranges defined below, there is a corresponding Is_xxx.. predicate
- -- which is to be used in preference to direct range tests using the
- -- subtype name. However, the subtype names are available for direct
- -- use, e.g. as choices in case statements.

- -- 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).
-
- -------------------------------
- -- Handling of Discriminants --
- -------------------------------
-
- -- During semantic processing, discriminants are separate entities which
- -- 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
- -- Component_Size Uint_0
- -- Component_Bit_Offset No_Uint
- -- Digits_Value Uint_0
- -- Esize Uint_0
- -- Normalized_First_Bit No_Uint
- -- Normalized_Position No_Uint
- -- Normalized_Position_Max No_Uint
- -- RM_Size Uint_0
-
- -- It would be cleaner to use No_Uint in all these cases, but historically
- -- 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
- -- have an RM_Size value of zero).
