+package Einfo is
+
+-- This package defines the annotations to the abstract syntax tree that
+-- are needed to support semantic processing of an Ada compilation.
+
+-- Note that after editing this spec and the corresponding body it is
+-- required to run ceinfo to check the consistentcy of spec and body.
+-- See ceinfo.adb for more information about the checks made.
+
+-- 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,
+-- einfo.h from the spec and body of package Einfo. It reads the input
+-- files einfo.ads and einfo.adb and produces the output file einfo.h.
+-- XEINFO is run automatically by the build scripts when you do a full
+-- bootstrap.
+
+-- 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 einfo.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 be 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
+-- other 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.
+
+-- All size attributes are stored as Uint values. Negative values are used to
+-- reference GCC expressions for the case of non-static sizes, as explained
+-- in Repinfo.
+
+-----------------------
+-- Entity Attributes --
+-----------------------
+
+-- This section contains a complete list of the attributes that are defined
+-- on entities. Some attributes apply to all entities, others only to certain
+-- kinds of entities. In the latter case the attribute should only be set or
+-- accessed if the Ekind field indicates an appropriate entity.
+
+-- There are two kinds of attributes that apply to entities, stored and
+-- synthesized. Stored attributes correspond to a field or flag in the entity
+-- itself. Such attributes are identified in the table below by giving the
+-- field or flag in the attribute that is used to hold the attribute value.
+-- Synthesized attributes are not stored directly, but are rather computed as
+-- needed from other attributes, or from information in the tree. These are
+-- marked "synthesized" in the table below. The stored attributes have both
+-- access functions and set procedures to set the corresponding values, while
+-- synthesized attributes have only access functions.
+
+-- Note: in the case of Node, Uint, or Elist fields, there are cases where
+-- the same physical field is used for different purposes in different
+-- entities, so these access functions should only be referenced for the
+-- class of entities in which they are defined as being present. Flags are
+-- not overlapped in this way, but nevertheless as a matter of style and
+-- abstraction (which may or may not be checked by assertions in the body),
+-- this restriction should be observed for flag fields as well.
+
+-- Note: certain of the attributes on types apply only to base types, and
+-- are so noted by the notation [base type only]. These are cases where the
+-- attribute of any subtype is the same as the attribute of the base type.
+-- The attribute can be referenced on a subtype (and automatically retrieves
+-- the value from the base type). However, it is an error to try to set the
+-- attribute on other than the base type, and if assertions are enabled,
+-- an attempt to set the attribute on a subtype will raise an assert error.
+
+-- Other attributes are noted as applying to the [implementation base type
+-- only]. These are representation attributes which must always apply to a
+-- full non-private type, and where the attributes are always on the full
+-- type. The attribute can be referenced on a subtype (and automatically
+-- retries the value from the implementation base type). However, it is an
+-- error to try to set the attribute on other than the implementation base
+-- type, and if assertions are enabled, an attempt to set the attribute on a
+-- subtype will raise an assert error.
+
+-- Accept_Address (Elist21)
+-- Present in entries. If an accept has a statement sequence, then an
+-- address variable is created, which is used to hold the address of the
+-- parameters, as passed by the runtime. Accept_Address holds an element
+-- list which represents a stack of entities for these address variables.
+-- The current entry is the top of the stack, which is the last element
+-- on the list. A stack is required to handle the case of nested select
+-- statements referencing the same entry.
+
+-- Actual_Subtype (Node17)
+-- Present in variables, constants, and formal parameters. This is the
+-- subtype imposed by the value of the object, as opposed to its nominal
+-- subtype, which is imposed by the declaration. The actual subtype
+-- differs from the nominal one when the latter is indefinite (as in the
+-- case of an unconstrained formal parameter, or a variable declared
+-- with an unconstrained type and an initial value). The nominal subtype
+-- is the Etype entry for the entity. The Actual_Subtype field is set
+-- only if the actual subtype differs from the nominal subtype. If the
+-- actual and nominal subtypes are the same, then the Actual_Subtype
+-- field is Empty, and Etype indicates both types.
+--
+-- For objects, the Actual_Subtype is set only if this is a discriminated
+-- type. For arrays, the bounds of the expression are obtained and the
+-- Etype of the object is directly the constrained subtype. This is
+-- rather irregular, and the semantic checks that depend on the nominal
+-- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).
+
+-- Access_Disp_Table (Elist16) [implementation base type only]
+-- Present in record type entities. For a tagged type, points to the
+-- dispatch tables associated with the tagged type. The first two
+-- entities correspond with the primary dispatch table: 1) primary
+-- dispatch table with user-defined primitives, 2) primary dispatch table
+-- with predefined primitives. For each interface type covered by the
+-- tagged type we also have: 3) secondary dispatch table with thunks of
+-- primitives covering user-defined interface primitives, 4) secondary
+-- dispatch table with thunks of predefined primitives, 5) secondary
+-- dispatch table with user-defined primitives, and 6) secondary dispatch
+-- table with predefined primitives. The last entity of this list is an
+-- access type declaration used to expand dispatching calls through the
+-- primary dispatch table. 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, and also in
+-- the case of subprograms to control output of certain warnings.
+
+-- Alias (Node18)
+-- Present in overloaded entities (literals, subprograms, entries) and
+-- subprograms that cover a primitive operation of an abstract interface
+-- (that is, subprograms with the Interface_Alias attribute). In case of
+-- overloaded entities it points to the parent subprogram of a derived
+-- subprogram. In case of abstract interface subprograms it points to the
+-- subprogram that covers the abstract interface primitive. Also used for
+-- a subprogram renaming, where it points to the renamed subprogram.
+-- Always empty for entries.
+
+-- Alignment (Uint14)
+-- Present in entities for types and also in constants, variables
+-- (including exceptions where it refers to the static data allocated for
+-- an exception), loop parameters, and formal parameters. 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 has not
+-- been set yet. 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 as part of the back end back-annotation process. The
+-- alignment field is also present in E_Exception entities, but there it
+-- is used only by the back-end for back annotation.
+
+-- Alignment_Clause (synthesized)
+-- Applies 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.
+
+-- Available_View (synthesized)
+-- Applies to types that have the With_Type flag set. Returns the
+-- non-limited view of the type, if available, otherwise the type
+-- itself. For class-wide types, there is no direct link in the tree,
+-- so we have to retrieve the class-wide type of the non-limited view
+-- of the Etype.
+
+-- 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, and
+-- also for accessibility checks on anonymous access types. This
+-- node is typically an object declaration, component declaration,
+-- type or subtype declaration. For an access discriminant in a type
+-- declaration, the associated_node_for_itype is the discriminant
+-- specification. For an access parameter it is the enclosing subprogram
+-- declaration.
+
+-- Associated_Storage_Pool (Node22) [root type only]
+-- Present in simple and general access type entities. References the
+-- storage pool to be used for the corresponding collection. A value of
+-- Empty means that the default pool is to be used. This is present
+-- only in the root type, since derived types must have the same pool
+-- as the parent type.
+
+-- Associated_Final_Chain (Node23)
+-- Present in simple and general access type entities. References the
+-- List_Controller object that holds the finalization chain on which
+-- are attached dynamically allocated objects referenced by the access
+-- type. Empty when the access type cannot reference a controlled object.
+
+-- Barrier_Function (Node12)
+-- Present in protected entries and entry families. This is the
+-- subprogram declaration for the body of the function that returns
+-- the value of the entry barrier.
+
+-- Base_Type (synthesized)
+-- Applies to all type entities. Returns the base type of a type or
+-- subtype. The base type of a type is the type itself. The base type
+-- of a subtype is the type that it constrains (which is always a type
+-- entity, not some other subtype). Note that in the case of a subtype
+-- of a private type, it is possible for the base type attribute to
+-- return a private type, even if the subtype to which it applies is
+-- non-private. See also Implementation_Base_Type. Note: it is allowed
+-- to apply Base_Type to other than a type, in which case it simply
+-- returns the entity unchanged.
+
+-- Block_Node (Node11)
+-- Present in block entities. Points to the identifier in the
+-- Block_Statement itself. Used when retrieving the block construct
+-- for finalization purposes, The block entity has an implicit label
+-- declaration in the enclosing declarative part, and has otherwise
+-- no direct connection in the tree with the block statement. The
+-- link is to the identifier (which is an 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.
+
+-- Body_Needed_For_SAL (Flag40)
+-- Present in package and subprogram entities that are compilation
+-- units. Indicates that the source for the body must be included
+-- when the unit is part of a standalone library.
+
+-- 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).
+
+-- Can_Never_Be_Null (Flag38)
+-- This flag is present in all entities, but can only be set in an object
+-- which can never have a null value. This is set True for constant
+-- access values initialized to a non-null value. This is also True for
+-- all access parameters in Ada 83 and Ada 95 modes, and for access
+-- parameters that explicily exlude null in Ada 2005.
+--
+-- This is used to avoid unnecessary resetting of the Is_Known_Non_Null
+-- flag for such entities. In Ada 2005 mode, this is also used when
+-- determining subtype conformance of subprogram profiles to ensure
+-- that two formals have the same null-exclusion status.
+--
+-- ??? This is also set on some access types, eg the Etype of the
+-- anonymous access type of a controlling formal.
+
+-- 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.
+
+-- Checks_May_Be_Suppressed (Flag31)
+-- Present in all entities. Set if a pragma Suppress or Unsuppress
+-- mentions the entity specifically in the second argument. If this
+-- flag is set the Global_Entity_Suppress and Local_Entity_Suppress
+-- tables must be consulted to determine if the is actually an active
+-- Suppress or Unsuppress pragma that applies to the entity.
+
+-- 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 appearance 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_Clause 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 No_Uint means that the value is not yet set.
+-- The value can be set by the use of a component size clause, or
+-- by the front end in package Layout, or by the backend. A negative
+-- value is used to represent a value which is not known at compile
+-- time, and must be computed at run-time (this happens if the type
+-- of the component has a variable length size). See package Layout
+-- for details of these values.
+
+-- Component_Type (Node20) [implementation base type only]
+-- Present in array types and string types. References component type.
+
+-- Constant_Value (synthesized)
+-- Applies to variables, constants, named integers, and named reals.
+-- Obtains the initialization expression for the entity. Will return
+-- Empty 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. Empty is
+-- also returned for variables with no initialization expression.
+
+-- 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.
+
+-- Current_Use_Clause (Node27)
+-- Present in packages and in types. For packages, denotes the use
+-- package clause currently in scope that makes the package use_visible.
+-- For types, it denotes the use_type clause that makes the operators of
+-- the type visible. Used for more precise warning messages on redundant
+-- use clauses.
+
+-- Current_Value (Node9)
+-- Present in all object entities. Set in E_Variable, E_Constant, formal
+-- parameters and E_Loop_Parameter entities if we have trackable current
+-- values. Set non-Empty if the (constant) current value of the variable
+-- is known, This value is valid only for references from the same
+-- sequential scope as the entity. The sequential scope of an entity
+-- includes the immediate scope and any contained scopes that are package
+-- specs, package bodies, blocks (at any nesting level) or statement
+-- sequences in IF or loop statements.
+--
+-- Another related use of this field is to record information about the
+-- value obtained from an IF or WHILE statement condition. If the IF or
+-- ELSIF or WHILE condition has the form "NOT {,NOT] OBJ RELOP VAL ",
+-- or OBJ [AND [THEN]] expr, where OBJ refers to an entity with a
+-- Current_Value field, RELOP is one of the six relational operators, and
+-- VAL is a compile-time known value then the Current_Value field of OBJ
+-- points to the N_If_Statement, N_Elsif_Part, or N_Iteration_Scheme node
+-- of the relevant construct, and the Condition field of this can be
+-- consulted to give information about the value of OBJ. For more details
+-- on this usage, see the procedure Exp_Util.Get_Current_Value_Condition.
+
+-- 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. Note that this
+-- flag is only for use by the front end as part of the processing for
+-- determining if Needs_Debug_Info should be set. The back end should
+-- always test Needs_Debug_Info, it should never test Debug_Info_Off.
+
+-- Debug_Renaming_Link (Node25)
+-- Used to link the variable associated with 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. This flag is
+-- set to False if a Keep_Names pragma appears for an enumeration type.
+
+-- 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 "Handling of Discriminants" for
+-- full details of the use of discriminals.
+
+-- 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_Discriminants 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.
+
+-- Dispatch_Table_Wrapper (Node26) [implementation base type only]
+-- Present in library level record type entities if we are generating
+-- statically allocated dispatch tables. For a tagged type, points to
+-- the dispatch table wrapper associated with the tagged type. For a
+-- non-tagged record, contains Empty.
+
+-- 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_Offset_To_Top_Func (Node25)
+-- Present in E_Component entities. Only used for component marked
+-- Is_Tag. If present it stores the Offset_To_Top function used to
+-- provide this value in tagged types whose ancestor has discriminants.
+
+-- 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_Body_Desirable (Flag210)
+-- Present in package entities. Set if the elaboration circuitry detects
+-- a case where there is a package body that modifies one or more visible
+-- entities in the package spec and there is no explicit Elaborate_Body
+-- pragma for the package. This information is passed on to the binder,
+-- which attempts, but does not promise, to elaborate the body as close
+-- to the spec as possible.
+
+-- Elaboration_Entity (Node13)
+-- Present in generic and non-generic package and subprogram
+-- entities. This is a boolean entity associated with the unit that
+-- is initially 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)
+-- Applies 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, and also for components, constants,
+-- and variables, including exceptions where it refers to the static data
+-- allocated for an exception. 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. For
+-- a class wide type, points to the parent type. For a subprogram or
+-- subprogram type, Etype has the return type of a function or is set
+-- to Standard_Void_Type to represent a procedure.
+
+-- 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_Formals (Node28)
+-- Applies to subprograms and subprogram types, and also in entries
+-- and entry families. Returns first extra formal of the subprogram
+-- or entry. Returns Empty if there are no 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.
+
+-- Can_Use_Internal_Rep (Flag229) [base type only]
+-- Present in Access_Subprogram_Kind nodes. This flag is set by the
+-- front end and used by the back end. False means that the back end
+-- must represent the type in the same way as Convention-C types (and
+-- other foreign-convention types). On many targets, this means that
+-- the back end will use dynamically generated trampolines for nested
+-- subprograms. True means that the back end can represent the type in
+-- some internal way. On the aforementioned targets, this means that the
+-- back end will not use dynamically generated trampolines. This flag
+-- must be False if Has_Foreign_Convention is True; otherwise, the front
+-- end is free to set the policy.
+--
+-- Setting this False in all cases corresponds to the traditional back
+-- end strategy, where all access-to-subprogram types are represented the
+-- same way, independent of the Convention. See also
+-- Always_Compatible_Rep in Targparm.
+--
+-- Efficiency note: On targets that use dynamically generated
+-- trampolines, False generally favors efficiency of top-level
+-- subprograms, whereas True generally favors efficiency of nested
+-- ones. On other targets, this flag has little or no effect on
+-- efficiency. The front end should take this into account. In
+-- particular, pragma Favor_Top_Level gives a hint that the flag should
+-- be False.
+--
+-- Note: We considered using Convention-C for this purpose, but we need
+-- this separate flag, because Convention-C implies that for
+-- P'[Unrestricted_]Access, P also have convention C. Sometimes we want
+-- to have Can_Use_Internal_Rep False for an access type, but allow P to
+-- have convention Ada.
+
+-- Finalization_Chain_Entity (Node19)
+-- Present in scopes that can have finalizable entities (blocks,
+-- functions, procedures, tasks, entries, return statements). 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_Component_Or_Discriminant (synthesized)
+-- Similar to First_Component, but discriminants are not skipped, so will
+-- find the first discriminant if discriminants are present.
+
+-- 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_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_Formal_With_Extras (synthesized)
+-- Applies to subprograms and subprogram types, and also in entries
+-- and entry families. Returns first formal of the subprogram or entry.
+-- Returns Empty if there are no formals. The list returned includes
+-- all the extra formals (see description of Extra_Formals field).
+
+-- 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.
+-- Note that this field is set in enumeration subtypes, but it still
+-- points to the first literal of the base type in this case.
+
+-- 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.
+--
+-- Note: pragmas that can apply to more than one overloadable entity,
+-- (Convention, Interface, Inline, Inline_Always, Import, Export,
+-- External) are never present on this chain when they apply to
+-- overloadable entities, since it is impossible for a given pragma
+-- to be on more than one chain at a time.
+--
+-- 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_Stored_Discriminant (synthesized)
+-- Applies to types with discriminants. Gives the first discriminant
+-- stored in the object. In many cases, these are the same as the
+-- normal visible discriminants for the type, but in the case of
+-- renamed discriminants, this is not always the case.
+--
+-- For tagged types, and untagged types which are root types or
+-- derived types but which do not rename discriminants in their
+-- root type, the stored discriminants are the same as the actual
+-- discriminants of the type, and hence this function 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 occur in the
+-- root type. To be precise, in this case stored 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 since although they are actually
+-- stored in the object, they are not in the set of discriminants that
+-- is visble in the type.
+--
+-- For derived untagged types, stored discriminants are the real
+-- discriminants from Gigi's standpoint, i.e. those that will be
+-- stored in actual objects of the type.
+
+-- 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.
+
+-- First_Tag_Component (synthesized)
+-- Applies to tagged record types, returns the entity for the first
+-- _Tag field in this record.
+
+-- 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.
+-- Currently this flag is also used to implement Ada 2005 (AI-50217).
+-- It will be renamed to From_Limited_With after removal of the current
+-- GNAT with_type clause???
+
+-- 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.
+
+-- Generic_Homonym (Node11)
+-- Present in generic packages. The generic homonym is the entity of
+-- a renaming declaration inserted in every generic unit. It is used
+-- to resolve the name of a local entity that is given by a qualified
+-- name, when the generic entity itself is hidden by a local name.
+
+-- 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.
+
+-- 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_Anon_Block_Suffix (Flag201)
+-- Present in all entities. Set if the entity is nested within one or
+-- more anonymous blocks and the Chars field contains a name with an
+-- anonymous block suffix (see Exp_Dbug for furthert details).
+
+-- 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,
+-- constants and packages that require a body). The flag is set if the
+-- completion has been encountered and analyzed.
+
+-- Has_Completion_In_Body (Flag71)
+-- Present in all entities for types and subtypes. Set only in "Taft
+-- amendment types" (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_Constrained_Partial_View (Flag187)
+-- Present in private type and their completions, when the private
+-- type has no discriminants and the full view has discriminants with
+-- defaults. In Ada 2005 heap-allocated objects of such types are not
+-- constrained, and can change their discriminants with full assignment.
+
+-- Has_Contiguous_Rep (Flag181)
+-- Present in enumeration types. True if the type as a representation
+-- clause whose entries are successive integers.
+
+-- 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 all entities. Set only for composite type entities which
+-- contain a component that either is a controlled type, or itself
+-- contains controlled component (i.e. either Has_Controlled_Component
+-- or Is_Controlled is set for at least one component).
+
+-- Has_Convention_Pragma (Flag119)
+-- Present in all entities. Set true for an entity for which a valid
+-- 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_Dispatch_Table (Flag220)
+-- Present in E_Record_Types that are tagged. Set to indicate that the
+-- corresponding dispatch table is already built. This flag is used to
+-- avoid duplicate construction of library level dispatch tables (because
+-- the declaration of library level objects cause premature construction
+-- of the table); otherwise the code that builds the table is added at
+-- the end of the list of declarations of the package.
+
+-- 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)
+-- Present in all entities. 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
+-- Linker_Constructor pragma
+-- Linker_Destructor 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_Initial_Value (Flag219)
+-- Present in entities for variables and out parameters. Set if there
+-- is an explicit initial value expression in the declaration of the
+-- variable. Note that this is set only if this initial value is
+-- explicit, it is not set for the case of implicit initialization
+-- of access types or controlled types. Always set to False for out
+-- parameters. Also present in entities for in and in-out parameters,
+-- but always false in these cases.
+--
+-- Has_Interrupt_Handler (synthesized)
+-- Applies to all protected type 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_Up_Level_Access (Flag215)
+-- Present in E_Variable and E_Constant entities. Set if the entity
+-- is a local variable declared in a subprogram p and is accessed in
+-- a subprogram nested inside p. Currently this flag is only set when
+-- VM_Target /= No_VM, for efficiency, since only the .NET back-end
+-- makes use of it to generate proper code for up-level references.
+
+-- 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. Per object constraints result
+-- from the following situations:
+--
+-- 1. N_Attribute_Reference - when the prefix is the enclosing type and
+-- the attribute is Access.
+-- 2. N_Discriminant_Association - when the expression uses the
+-- discriminant of the enclosing type.
+-- 3. N_Index_Or_Discriminant_Constraint - when at least one of the
+-- individual constraints is a per object constraint.
+-- 4. N_Range - when the lower or upper bound uses the discriminant of
+-- the enclosing type.
+-- 5. N_Range_Constraint - when the range expression uses the
+-- discriminant of the enclosing type.
+
+-- Has_Persistent_BSS (Flag188)
+-- Present in all entities. Set True for entities to which a valid
+-- pragma Persistent_BSS applies. Note that although the pragma is
+-- only meaningful for objects, we set it for all entities in a unit
+-- to which the pragma applies, as well as the unit entity itself, for
+-- convenience in propagating the flag to contained entities.
+
+-- Has_Postconditions (Flag240)
+-- Present in subprogram entities. Set if postconditions are active for
+-- the procedure, and a _postconditions procedure has been generated.
+
+-- 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 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_Inline_Always (Flag230)
+-- Present in all entities. Set for functions and procedures for which a
+-- pragma Inline_Always applies. Note that if this flag is set, the flag
+-- Has_Pragma_Inline is also set.
+
+-- Has_Pragma_Pack (Flag121) [implementation base type only]
+-- Present in all entities. If set, indicates that a valid pragma Pack
+-- was given for the type. Note that this flag is not inherited by
+-- derived type. See also the Is_Packed flag.
+
+-- Has_Pragma_Pure (Flag203)
+-- Present in all entities. If set, indicates that a valid pragma Pure
+-- was given for the entity. In some cases, we need to test whether
+-- Is_Pure was explicitly set using this pragma.
+
+-- Has_Pragma_Preelab_Init (Flag221)
+-- Present in type and subtype entities. If set indicates that a valid
+-- pragma Preelaborable_Initialization applies to the type.
+
+-- Has_Pragma_Pure_Function (Flag179)
+-- Present in all entities. If set, indicates that a valid pragma
+-- Pure_Function was given for the entity. In some cases, we need to
+-- know that Is_Pure was explicitly set using this pragma.
+
+-- Has_Pragma_Unmodified (Flag233)
+-- Present in all entities. Can only be set for variables (E_Variable,
+-- E_Out_Parameter, E_In_Out_Parameter). Set if a valid pragma Unmodified
+-- applies to the variable, indicating that no warning should be given
+-- if the entity is never modified. Note that clients should generally
+-- not test this flag directly, but instead use function Has_Unmodified.
+
+-- Has_Pragma_Unreferenced (Flag180)
+-- Present in all entities. Set if a valid pragma Unreferenced applies
+-- to the entity, indicating that no warning should be given if the
+-- entity has no references, but a warning should be given if it is
+-- in fact referenced. For private types, this flag is set in both the
+-- private entity and full entity if the pragma applies to either. Note
+-- that clients should generally not test this flag directly, but instead
+-- use function Has_Unreferenced.
+
+-- Has_Pragma_Unreferenced_Objects (Flag212)
+-- Present in type and subtype entities. Set if a valid pragma
+-- Unreferenced_Objects applies to the type, indicating that no warning
+-- should be given for objects of such a type for being unreferenced
+-- (but unlike the case with pragma Unreferenced, it is ok to reference
+-- such an object and no warning is generated.
+
+-- Has_Primitive_Operations (Flag120) [base type only]
+-- Present in all type entities. Set if at least one primitive operation
+-- is defined for the type.
+
+-- Has_Private_Ancestor (synthesized)
+-- Applies to all type and subtype entities. Returns True if at least
+-- one ancestor is private, and otherwise False if there are no private
+-- ancestors.
+
+-- Has_Private_Declaration (Flag155)
+-- Present in all entities. Returns True if it is the defining entity
+-- of a private type declaration or its corresponding full declaration.
+-- This flag is thus preserved when the full and the partial views are
+-- exchanged, to indicate if a full type declaration is a completion.
+-- Used for semantic checks in E.4 (18), and elsewhere.
+
+-- Has_Qualified_Name (Flag161)
+-- Present in all entities. Set True if the name in the Chars field
+-- has been replaced by its qualified name, as used for debug output.
+-- See Exp_Dbug for a full description of qualification requirements.
+-- For some entities, the name is the fully qualified name, but there
+-- are exceptions. In particular, for local variables in procedures,
+-- we do not include the procedure itself or higher scopes. See also
+-- the flag Has_Fully_Qualified_Name, which is set if the name does
+-- indeed include the fully qualified name.
+
+-- Has_RACW (Flag214)
+-- Present in package spec entities. Set if the spec contains the
+-- declaration of a remote access-to-classwide type.
+
+-- Has_Record_Rep_Clause (Flag65) [implementation base type only]
+-- Present in record types. Set if a record representation clause has
+-- been given for this record type. Used to prevent more than one such
+-- clause for a given record type. Note that this is initially cleared
+-- for a derived type, even though the representation is inherited. See
+-- also the flag Has_Specified_Layout.
+
+-- Has_Recursive_Call (Flag143)
+-- Present in procedures. Set if a direct parameterless recursive call
+-- is detected while analyzing the body. Used to activate some error
+-- checks for infinite recursion.
+
+-- Has_Size_Clause (Flag29)
+-- Present in entities for types and objects. Set if a size clause is
+-- present for the entity. Used to prevent multiple Size clauses for a
+-- given entity. Note that it is always initially cleared for a derived
+-- type, even though the Size for such a type is inherited from a Size
+-- clause given for the parent type.
+
+-- Has_Small_Clause (Flag67)
+-- Present in ordinary fixed point types (but not subtypes). Indicates
+-- that a small clause has been given for the entity. Used to prevent
+-- multiple Small clauses for a given entity. Note that it is always
+-- initially cleared for a derived type, even though the Small for such
+-- a type is inherited from a Small clause given for the parent type.
+
+-- Has_Specified_Layout (Flag100) [implementation base type only]
+-- Present in all type entities. Set for a record type or subtype if
+-- the record layout has been specified by a record representation
+-- clause. Note that this differs from the flag Has_Record_Rep_Clause
+-- in that it is inherited by a derived type. Has_Record_Rep_Clause is
+-- used to indicate that the type is mentioned explicitly in a record
+-- representation clause, and thus is not inherited by a derived type.
+-- This flag is always False for non-record types.
+
+-- Has_Specified_Stream_Input (Flag190)
+-- Has_Specified_Stream_Output (Flag191)
+-- Has_Specified_Stream_Read (Flag192)
+-- Has_Specified_Stream_Write (Flag193)
+-- Present in all type and subtype entities. Set for a given view if the
+-- corresponding stream-oriented attribute has been defined by an
+-- attribute definition clause. When such a clause occurs, a TSS is set
+-- on the underlying full view; the flags are used to track visibility of
+-- the attribute definition clause for partial or incomplete views.
+--
+-- Has_Static_Discriminants (Flag211)
+-- Present in record subtypes constrained by discriminant values. Set if
+-- all the discriminant values have static values, meaning that in the
+-- case of a variant record, the component list can be trimmed down to
+-- include only the components corresponding to these discriminants.
+--
+-- 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_Stream_Size_Clause (Flag184)
+-- Present in all entities. It is set for types which have a Stream_Size
+-- clause attribute. Used to prevent multiple Stream_Size clauses for a
+-- given entity, and also whether it is necessary to check for a stream
+-- size clause.
+
+-- 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 or declaration of
+-- such an object must create the required tasks. Note: the flag is not
+-- set on access types, even if they designate an object that Has_Task.
+
+-- Has_Thunks (Flag228)
+-- Applies to E_Constant entities marked Is_Tag. True for secondary tag
+-- referencing a dispatch table whose contents are pointers to thunks.
+
+-- 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 entities. Set for types with unknown discriminants.
+-- 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. Note that both Has_Discriminants and
+-- Has_Unknown_Discriminants may be true for a type. Class-wide types and
+-- their subtypes have unknown discriminants and can have declared ones
+-- as well. Private types declared with unknown discriminants may have a
+-- full view that has explicit discriminants, and both flag will be set
+-- on the partial view, to insure that discriminants are properly
+-- inherited in certain contexts.
+
+-- 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.
+
+-- Has_Xref_Entry (Flag182)
+-- Present in all entities. Set if an entity has an entry in the Xref
+-- information generated in ali files. This is true for all source
+-- entities in the extended main source file. It is also true of entities
+-- in other packages that are referenced directly or indirectly from the
+-- main source file (indirect reference occurs when the main source file
+-- references an entity with a type reference. See package Lib.Xref for
+-- further details).
+
+-- 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_Parameter 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 entities. For 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 Underlying_Type of the base type, so
+-- that we still have a concrete type. For entities other than types,
+-- returns the entity unchanged.
+
+-- Implemented_By_Entry (Flag232)
+-- Applies to functions and procedures. Set if pragma Implemented_By_
+-- Entry is applied on the subprogram entity.
+
+-- Interfaces (Elist25)
+-- Present in record types and subtypes. List of abstract interfaces
+-- implemented by a tagged type that are not already implemented by the
+-- ancestors (Ada 2005: AI-251).
+
+-- Interface_Alias (Node25)
+-- Present in subprograms that cover a primitive operation of an abstract
+-- interface type. Can be set only if the Is_Hidden flag is also set,
+-- since such entities are always hidden. Points to its associated
+-- interface subprogram. It is used to register the subprogram in
+-- secondary dispatch table of the interface (Ada 2005: AI-251).
+
+-- In_Package_Body (Flag48)
+-- Present in package entities. 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 all entities. Can be set only in package entities and
+-- objects. For package entities, this flag is set to indicate that the
+-- private part of the package is being analyzed. The flag is reset at
+-- the end of the package declaration. For objects it indicates that the
+-- declaration of the object occurs in the private part of a package.
+
+-- 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
+-- external 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_Subprogram (Flag19)
+-- Present in all subprograms and entries. Set for abstract subprograms.
+-- Always False for enumeration literals and entries. See also
+-- Requires_Overriding.
+
+-- Is_Abstract_Type (Flag146)
+-- Present in all types. Set for abstract types.
+
+-- Is_Access_Constant (Flag69)
+-- Present in access types and subtypes. Indicates that the keyword
+-- constant was present in the access type definition.
+
+-- Is_Access_Protected_Subprogram_Type (synthesized)
+-- Applies to all types, true for named and anonymous access to
+-- protected subprograms.
+
+-- Is_Access_Type (synthesized)
+-- Applies to all entities, true for access types and subtypes
+
+-- Is_Ada_2005_Only (Flag185)
+-- Present in all entities, true if a valid pragma Ada_05 applies to the
+-- entity which specifically names the entity, indicating that the entity
+-- is Ada 2005 only. Note that this flag is not set if the entity is part
+-- of a unit compiled with the normal no-argument form of pragma Ada_05.
+
+-- Is_Aliased (Flag15)
+-- Present in objects whose declarations carry the keyword aliased,
+-- and on record components that have the keyword.
+
+-- Is_AST_Entry (Flag132)
+-- Present in entry entities. Set if a valid pragma AST_Entry applies
+-- to the entry. This flag can only be set in OpenVMS versions of GNAT.
+-- Note: we also allow the flag to appear in entry families, but given
+-- the current implementation of the pragma AST_Entry, this flag will
+-- always be False in entry families.
+
+-- Is_Atomic (Flag85)
+-- Present in all type entities, and also in constants, components and
+-- variables. Set if a pragma Atomic or Shared applies to the entity.
+-- In the case of private and incomplete types, this flag is set in
+-- both the partial view and the full view.
+
+-- Is_Array_Type (synthesized)
+-- Applies to all entities, true for array types and subtypes
+
+-- Is_Asynchronous (Flag81)
+-- Present in all type entities and in procedure entities. Set
+-- if a pragma Asynchronous applies to the entity.
+
+-- Is_Bit_Packed_Array (Flag122) [implementation base type only]
+-- Present in all entities. This flag is set for a packed array type that
+-- is bit packed (i.e. the component size is known by the front end and
+-- is in the range 1-7, 9-15, 17-31, or 33-63). 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 for the case of an array having one or
+-- more index types that are enumeration types with non-standard
+-- enumeration representations.
+
+-- Is_Boolean_Type (synthesized)
+-- Applies to all entities, true for boolean types and subtypes,
+-- i.e. Standard.Boolean and all types ultimately derived from it.
+
+-- 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. Set 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_Class_Wide_Equivalent_Type (Flag35)
+-- Present in record types and subtypes. Set to True, if the type acts
+-- as a class-wide equivalent type, i.e. the Equivalent_Type field of
+-- some class-wide subtype entity references this record type.
+
+-- 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)
+-- Present in all entities. This flag can be set only for E_Discriminant
+-- entities. 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: there are girder discriminants
+-- which are not Completely_Hidden (e.g. 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_Constant_Object (synthesized)
+-- Applies to all entities, true for E_Constant, E_Loop_Parameter, and
+-- E_In_Parameter entities.
+
+-- 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)
+-- Present in all types and subtypes. This flag can be set only if
+-- Is_Constr_Subt_For_U_Nominal is also 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]
+-- Present in all type entities. Indicates that the type is controlled,
+-- i.e. is either a descendant of Ada.Finalization.Controlled or of
+-- Ada.Finalization.Limited_Controlled.
+
+-- Is_Controlling_Formal (Flag97)
+-- Present in all Formal_Kind entities. Marks the controlling parameters
+-- of dispatching operations.
+
+-- Is_CPP_Class (Flag74)
+-- Present in all type entities, set only for tagged types to which a
+-- valid pragma Import (CPP, ...) or 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 entities. Determine if given entity is a derived type.
+-- Always false if argument is not a type.
+
+-- Is_Descendent_Of_Address (Flag223)
+-- Present in all type and subtype entities. Indicates that a type is an
+-- address type that is visibly a numeric type. Used for semantic checks
+-- on VMS to remove ambiguities in universal integer expressions that may
+-- have an address interpretation
+
+-- 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.
+
+-- Is_Discriminal (synthesized)
+-- Applies to all entities, true for renamings of discriminants. Such
+-- entities appear as constants or in parameters.
+
+-- Is_Dispatch_Table_Entity (Flag234)
+-- Applies to all entities. Set to indicate to the backend that this
+-- entity is associated with a dispatch table.
+
+-- Is_Dispatching_Operation (Flag6)
+-- 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, subprogram, task_type, entry
+-- or extended return statement).
+
+-- 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. Also used to mark subprogram entities whose
+-- declaration and body are within unreachable code that is removed.
+
+-- 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
+-- constrained array declarations).
+
+-- Is_Fixed_Point_Type (synthesized)
+-- Applies to all entities, true for decimal and ordinary fixed
+-- point types and subtypes
+
+-- Is_Floating_Point_Type (synthesized)
+-- Applies to all entities, true for float types and subtypes
+
+-- Is_Formal (synthesized)
+-- Applies to all entities, true for IN, IN OUT and OUT parameters
+
+-- Is_Formal_Object (synthesized)
+-- Applies to all entities, true for generic IN and IN OUT parameters
+
+-- Is_Formal_Subprogram (Flag111)
+-- Present in all entities. Set 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 and subtype entities. Set if type or subtype has
+-- been frozen.
+
+-- Is_Generic_Actual_Type (Flag94)
+-- Present in all type and subtype entities. Set 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, or a formal package (which is an instance
+-- of the template).
+
+-- Is_Generic_Subprogram (synthesized)
+-- Applies to all entities. Yields True for a generic subprogram
+-- (generic function, generic subprogram), False for all other entities.
+
+-- Is_Generic_Type (Flag13)
+-- Present in all types and subtypes. Set for 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_Incomplete_Type (synthesized)
+-- Applies to all entities, true for incomplete types and subtypes
+
+-- 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_Interface (Flag186)
+-- Present in record types and subtypes. Set to indicate that the current
+-- entity corresponds with an abstract interface. Because abstract
+-- interfaces are conceptually a special kind of abstract tagged types
+-- we represent them by means of tagged record types and subtypes
+-- marked with this attribute. This allows us to reuse most of the
+-- compiler support for abstract tagged types to implement interfaces
+-- (Ada 2005: AI-251).
+
+-- Is_Internal (Flag17)
+-- Present in all entities. Set to indicate an entity created during
+-- semantic processing (e.g. an implicit type, or a temporary). The
+-- current uses of this flag are:
+--
+-- 1) Internal entities (such as temporaries generated for the result
+-- of an inlined function call or dummy variables generated for the
+-- debugger). Set to indicate that they need not be initialized, even
+-- when scalars are initialized or normalized;
+--
+-- 2) Predefined primitives of tagged types. Set to mark that they
+-- have specific properties: first they are primitives even if they
+-- are not defined in the type scope (the freezing point is not
+-- necessarily in the same scope), and second the predefined equality
+-- can be overridden by a user-defined equality, no body will be
+-- generated in this case.
+--
+-- 3) Object declarations generated by the expander that are implicitly
+-- imported or exported so that they can be marked in Sprint output.
+--
+-- 4) Internal entities in the list of primitives of tagged types that
+-- are used to handle secondary dispatch tables. These entities have
+-- also the attribute Interface_Alias.
+--
+-- Is_Interrupt_Handler (Flag89)
+-- Present in procedures. Set if a pragma Interrupt_Handler applies
+-- to the procedure. The procedure must be parameterless, and on all
+-- targets except AAMP it must be a protected procedure.
+
+-- 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 to indicate that a type is an Itype,
+-- which means that 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_Non_Null (Flag37)
+-- Present in all entities. Relevant (and can be set True) only for
+-- objects of an access type. It is set if the object is currently
+-- known to have a non-null value (meaning that no access checks
+-- are needed). The indication can for example come from assignment
+-- of an access parameter or an allocator whose value is known non-null.
+--
+-- Note: this flag is set according to the sequential flow of the
+-- program, watching the current value of the variable. However,
+-- this processing can miss cases of changing the value of an aliased
+-- or constant object, so even if this flag is set, it should not
+-- be believed if the variable is aliased or volatile. It would
+-- be a little neater to avoid the flag being set in the first
+-- place in such cases, but that's trickier, and there is only
+-- one place that tests the value anyway.
+--
+-- The flag is dynamically set and reset as semantic analysis and
+-- expansion proceeds. Its value is meaningless once the tree is
+-- fully constructed, since it simply indicates the last state.
+-- Thus this flag has no meaning to the back end.
+
+-- Is_Known_Null (Flag204)
+-- Present in all entities. Relevant (and can be set True) only for
+-- objects of an access type. It is set if the object is currently known
+-- to have a null value (meaning that a dereference will surely raise
+-- constraint error exception). The indication can come from an
+-- assignment or object declaration.
+--
+-- The comments above about sequential flow and aliased and volatile for
+-- the Is_Known_Non_Null flag apply equally to the Is_Known_Null flag.
+
+-- 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.
+--
+-- The flag is dynamically set and reset as semantic analysis and
+-- expansion proceeds. Its value is meaningless once the tree is
+-- fully constructed, since it simply indicates the last state.
+-- Thus this flag has no meaning to the back end.
+
+-- Is_Limited_Composite (Flag106)
+-- Present in all entities. Set 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_Interface (Flag197)
+-- Present in record types and subtypes. True for interface types, if
+-- interface is declared limited, task, protected, or synchronized, or
+-- is derived from a limited interface.
+
+-- 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, limited interface type, task type, protected type,
+-- composite containing a limited component, or a subtype of any of
+-- these types).
+
+-- Is_Local_Anonymous_Access (Flag194)
+-- Present in access types. Set for an anonymous access type to indicate
+-- that the type is created for a record component with an access
+-- definition, an array component, or a stand-alone object. Such
+-- anonymous types have an accessibility level equal to that of the
+-- declaration in which they appear, unlike the anonymous access types
+-- that are created for access parameters and access discriminants.
+
+-- 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(3) have been performed.
+
+-- Is_Modular_Integer_Type (synthesized)
+-- Applies to all entities. True if entity is a modular integer type
+
+-- Is_Non_Static_Subtype (Flag109)
+-- 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_Obsolescent (Flag153)
+-- Present in all entities. Set for any entity for which a valid pragma
+-- Obsolescent applies.
+
+-- Is_Only_Out_Parameter (Flag226)
+-- Present in formal parameter entities. Set if this parameter is the
+-- only OUT parameter for this formal part. If there is more than one
+-- out parameter, or if there is some other IN OUT parameter then this
+-- flag is not set in any of them. Used in generation of warnings.
+
+-- 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_Overriding_Operation (Flag39)
+-- Present in subprograms. Set if the subprogram is a primitive
+-- operation of a derived type, that overrides an inherited operation.
+
+-- Is_Package_Or_Generic_Package (synthesized)
+-- Applies to all entities. True for packages and generic packages.
+-- False for all other entities.
+
+-- Is_Package_Body_Entity (Flag160)
+-- Present in all entities. Set for entities defined at the top level
+-- of a package body. Used to control externally generated names.
+
+-- Is_Packed (Flag51) [implementation base type only]
+-- Present in all type entities. This flag is set only for record and
+-- array types which have a packed representation. There are three
+-- cases which cause packing:
+--
+-- 1. Explicit use of pragma Pack for an array of package components
+-- 2. Explicit use of pragma Pack to pack a record
+-- 4. Setting Component_Size of an array to a bit-packable value
+-- 3. Indexing an array with a non-standard enumeration type.
+--
+-- For records, Is_Packed is always set if Has_Pack_Pragma is set,
+-- and can also be set on its own in a derived type which inherited
+-- its packed status.
+--
+-- For arrays, Is_Packed is set if an array is bit packed (i.e. the
+-- component size is known at compile time and is 1-7, 9-15 or 17-31),
+-- or if the array has one or more index types that are enumeration
+-- types with non-standard representations (in GNAT, we store such
+-- arrays compactly, using the Pos of the enumeration type value).
+--
+-- As for the case of records, Is_Packed can be set on its own for a
+-- derived type, with the same dual before/after freeze meaning.
+-- Is_Packed can also be set as the result of an explicit component
+-- size clause that specifies an appropriate component size.
+--
+-- In the bit packed array case, Is_Bit_Packed_Array will be set in
+-- the bit packed case once the array type is frozen.
+--
+-- Before an array type is frozen, Is_Packed will always be set if
+-- Has_Pack_Pragma is set. Before the freeze point, it is not possible
+-- to know the component size, since the component type is not frozen
+-- until the array type is frozen. Thus Is_Packed for an array type
+-- before it is frozen means that packed is required. Then if it turns
+-- out that the component size is not suitable for bit packing, the
+-- Is_Packed flag gets turned off.
+
+-- Is_Packed_Array_Type (Flag138)
+-- Present in all entities. This flag is set on the entity for the type
+-- used to implement a packed array (either a modular type, or a subtype
+-- of Packed_Bytes{1,2,4} as appropriate). The flag is set if and only
+-- if the type appears in the Packed_Array_Type field of some other type
+-- entity. It is used by Gigi to activate the special processing for such
+-- types (unchecked conversions that would not otherwise be allowed are
+-- allowed for such types). If the Is_Packed_Array_Type flag is set in
+-- an entity, then the Original_Array_Type field of this entity points
+-- to the original array type for which this is the packed array type.
+
+-- Is_Potentially_Use_Visible (Flag9)
+-- Present in all entities. Set if entity is potentially use visible,
+-- i.e. it is defined in a package that appears in a currently active
+-- use clause (RM 8.4(8)). Note that potentially use visible entities
+-- are not necessarily use visible (RM 8.4(9-11)).
+
+-- Is_Preelaborated (Flag59)
+-- Present in all entities, set in E_Package and E_Generic_Package
+-- entities to which a pragma Preelaborate is applied, and also in
+-- all entities within such packages. Note that the fact that this
+-- flag is set does not necesarily mean that no elaboration code is
+-- generated for the package.
+
+-- Is_Primitive (Flag218)
+-- Present in overloadable entities and in generic subprograms. Set to
+-- indicate that this is a primitive operation of some type, which may
+-- be a tagged type or a non-tagged type. Used to verify overriding
+-- indicators in bodies.
+
+-- Is_Primitive_Wrapper (Flag195)
+-- Present in functions and procedures created by the expander to serve
+-- as an indirection mechanism to overriding primitives of concurrent
+-- types, entries and protected procedures.
+
+-- Is_Prival (synthesized)
+-- Applies to all entities, true for renamings of private protected
+-- components. Such entities appear as constants or variables.
+
+-- 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 full 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_Primitive (Flag245)
+-- Present in subprograms. Set if the first parameter of the subprogram
+-- is of concurrent tagged type with a private view.
+
+-- 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_Component (synthesized)
+-- Applicable to all entities, true if the entity denotes a private
+-- component of a protected type.
+
+-- Is_Protected_Interface (Flag198)
+-- Present in types that are interfaces. True if interface is declared
+-- protected, or is derived from protected interfaces.
+
+-- Is_Protected_Type (synthesized)
+-- Applies to all entities, true for protected types and subtypes
+
+-- 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_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_Pure_Unit_Access_Type (Flag189)
+-- Present in access type and subtype entities. Set if the type or
+-- subtype appears in a pure unit. Used to give an error message at
+-- freeze time if the access type has a storage pool.
+
+-- Is_RACW_Stub_Type (Flag244)
+-- Present in all types, true for the stub types generated for remote
+-- access-to-class-wide types.
+
+-- Is_Raised (Flag224)
+-- Present in exception entities. Set if the entity is referenced by a
+-- a raise statement.
+
+-- 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_Interface is applied, and
+-- also on entities declared in the visible part of such a package.
+
+-- 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 on
+-- entities declared in the visible part of the spec of such a package.
+
+-- 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_Inherently_Limited_Type (synthesized)
+-- Applies to all type entities. True if the type is "inherently"
+-- limited (i.e. cannot become nonlimited). From the Ada 2005
+-- RM-7.5(8.1/2), "a type with a part that is of a task, protected, or
+-- explicitly limited record type". These are the types that are defined
+-- as return-by-reference types in Ada 95 (see RM95-6.5(11-16)). In Ada
+-- 2005, these are the types that require build-in-place for function
+-- calls. Note that build-in-place is allowed for other types, too.
+
+-- Is_Return_Object (Flag209)
+-- Present in all object entities. True if the object is the return
+-- object of an extended_return_statement; False otherwise.
+
+-- 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_Standard_Character_Type (synthesized)
+-- Applies to all entities, true for types and subtypes whose root type
+-- is one of the standard character types (Character, Wide_Character,
+-- Wide_Wide_Character).
+
+-- 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 object statically, its type must
+-- also be elaborated globally).
+
+-- 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_Subprogram (synthesized)
+-- Applies to all entities, true for function, procedure and operator
+-- entities.
+
+-- Is_Synchronized_Interface (Flag199)
+-- Present in types that are interfaces. True if interface is declared
+-- synchronized, task, or protected, or is derived from a synchronized
+-- interface.
+
+-- Is_Tag (Flag78)
+-- Present in E_Component and E_Constant entities. For regular tagged
+-- type this flag is set on the tag component (whose name is Name_uTag).
+-- 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. Set for an entity for a tagged type.
+
+-- Is_Task_Interface (Flag200)
+-- Present in types that are interfaces. True if interface is declared as
+-- a task interface, or if it is derived from task interfaces.
+
+-- 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_Thunk (Flag225)
+-- Present in all entities for subprograms (functions, procedures, and
+-- operators). True for subprograms that are thunks, that is small
+-- subprograms built by the expander for tagged types that cover
+-- interface types. At run-time thunks displace the pointer to the object
+-- (pointer named "this" in the C++ terminology) from a secondary
+-- dispatch table to the primary dispatch table associated with a given
+-- tagged type. Set by Expand_Interface Thunk and used by Expand_Call to
+-- handle extra actuals associated with accessibility level.
+
+-- Is_Trivial_Subprogram (Flag235)
+-- Present in all entities. Set in subprograms where either the body
+-- consists of a single null statement, or the first or only statement
+-- of the body raises an exception. This is used for suppressing certain
+-- warnings, see Sem_Ch6.Analyze_Subprogram_Body discussion for details.
+
+-- Is_True_Constant (Flag163)
+-- Present in all entities for constants and variables. 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.
+--
+-- Note: there is one situation in which the back end does not permit
+-- this flag to be set, even if no assignments are generated. This is
+-- the case of an object of a record or array type which is initialized
+-- with an aggregate, and is itself used as the expression initializing
+-- an atomic object, or the right hand side of an assignment to an atomic
+-- object. In this case the object must not have Is_True_Constant set,
+-- even though no assignments are generated (the reason for this is that
+-- the back end must not optimize the object away, because that would
+-- violate the restriction on aggregates in these positions).
+
+-- Is_Type (synthesized)
+-- Applies to all entities, true for a type entity
+
+-- Is_Unchecked_Union (Flag117) [implementation base type only]
+-- 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_Visible_Formal (Flag206)
+-- Present in all entities. Set for instances of the formals of a formal
+-- package. Indicates that the entity must be made visible in the body
+-- of the instance, to reproduce the visibility of the generic. This
+-- simplifies visibility settings in instance bodies.
+-- ??? confusion in above comments between being present and being set
+
+-- 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. The flag is not set reliably on private subtypes,
+-- and is always retrieved from the base type (but this is not a base-
+-- type-only attribute because it applies to other entities). Note that
+-- the back end should use Treat_As_Volatile, rather than Is_Volatile
+-- to indicate code generation requirements for volatile variables.
+-- Similarly, any front end test which is concerned with suppressing
+-- optimizations on volatile objects should test Treat_As_Volatile
+-- rather than testing this flag.
+
+-- Is_Wrapper_Package (synthesized)
+-- Present in package entities. Indicates that the package has been
+-- created as a wrapper for a subprogram instantiation.
+
+-- Itype_Printed (Flag202)
+-- Present in all type and subtype entities. Set in Itypes if the Itype
+-- has been printed by Sprint. This is used to avoid printing an Itype
+-- more than once.
+
+-- Kill_Elaboration_Checks (Flag32)
+-- Present in all entities. Set by the expander to kill elaboration
+-- checks which are known not to be needed. Equivalent in effect to
+-- the use of pragma Suppress (Elaboration_Checks) for that entity
+-- except that the effect is permanent and cannot be undone by a
+-- subsequent pragma Unsuppress.
+
+-- Kill_Range_Checks (Flag33)
+-- Present in all entities. Equivalent in effect to the use of pragma
+-- Suppress (Range_Checks) for that entity except that the result is
+-- permanent and cannot be undone by a subsequent pragma Unsuppress.
+-- This is currently only used in one odd situation in Sem_Ch3 for
+-- record types, and it would be good to get rid of it???
+
+-- Kill_Tag_Checks (Flag34)
+-- Present in all entities. Set by the expander to kill elaboration
+-- checks which are known not to be needed. Equivalent in effect to
+-- the use of pragma Suppress (Tag_Checks) for that entity except
+-- that the result is permanent and cannot be undone by a subsequent
+-- pragma Unsuppress.
+
+-- Known_To_Have_Preelab_Init (Flag207)
+-- Present in all type and subtype entities. If set, then the type is
+-- known to have preelaborable initialization. In the case of a partial
+-- view of a private type, it is only possible for this to be set if a
+-- pragma Preelaborable_Initialization is given for the type. For other
+-- types, it is never set if the type does not have preelaborable
+-- initialization, it may or may not be set if the type does have
+-- preelaborable initialization.
+
+-- Last_Assignment (Node26)
+-- Present in entities for variables, and OUT or IN OUT formals. Set for
+-- a local variable or formal to point to the left side of an assignment
+-- statement assigning a value to the variable. Cleared if the value of
+-- the entity is referenced. Used to warn about dubious assignment
+-- statements whose value is not used.
+
+-- 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 the last entry in the list of associated entities chained
+-- through the Next_Entity field. Empty if no entities are chained.
+
+-- Limited_View (Node23)
+-- Present in non-generic package entities that are not instances. Bona
+-- fide package with the limited-view list through the first_entity and
+-- first_private attributes. The elements of this list are the shadow
+-- entities created for the types and local packages that are declared
+-- in a package appearing in a limited_with clause (Ada 2005: AI-50217)
+
+-- 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 implementing 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.
+
+-- Low_Bound_Known (Flag205)
+-- Present in all entities. Currently this can only be set True for
+-- formal parameter entries of a standard unconstrained one-dimensional
+-- array or string type, where the lower bound of the index type is zero
+-- or one. Indicates that the low bound is known to be equal to the lower
+-- bound of the index type (e.g. 1 for String, since the index type is
+-- Positive). This flag can only be set by a pragma Assert which
+-- specifies this. If this flag is set, warnings about assuming the index
+-- low bound to be zero or one are suppressed.
+
+-- 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. Also set for access-to-
+-- limited-class-wide types whose root may be extended with task
+-- components, and for access-to-limited-interfaces because they can be
+-- used to reference tasks implementing such interface.
+
+-- Materialize_Entity (Flag168)
+-- Present in all entities. Set only for constant or renamed entities
+-- which should be materialized for debugging purposes. In the case of
+-- a constant, a memory location should be allocated containing the
+-- value. In the case of a renaming, a memory location containing the
+-- renamed address should be allocated.
+
+-- Mechanism (Uint8) (returned as Mechanism_Type)
+-- Present in functions and non-generic formal parameters. Indicates
+-- the mechanism to be used for the function return or for the formal
+-- parameter. See separate section on passing mechanisms. This field
+-- is also set (to the default value of zero) in a subprogram body
+-- entity but not used in this context.
+
+-- Modulus (Uint17) [base type only]
+-- Present in modular types. Contains the modulus. For the binary
+-- case, this will be a power of 2, but if Non_Binary_Modulus is
+-- set, then it will not be a power of 2.
+
+-- Must_Be_On_Byte_Boundary (Flag183)
+-- Present in entities for types and subtypes. Set if objects of
+-- the type must always be allocated on a byte boundary (more
+-- accurately a storage unit boundary). The front end checks that
+-- component clauses respect this rule, and the back end ensures
+-- that record packing does not violate this rule. Currently the
+-- flag is set only for packed arrays longer than 64 bits where
+-- the component size is not a power of 2.
+
+-- Must_Have_Preelab_Init (Flag208)
+-- Present in entities for types and subtypes. Set in the full type of a
+-- private type or subtype if a pragma Has_Preelaborable_Initialization
+-- is present for the private type. Used to check that the full type has
+-- preelaborable initialization at freeze time (this has to be deferred
+-- to the freeze point because of the rule about overriding Initialize).
+
+-- Needs_Debug_Info (Flag147)
+-- Present in all entities. Set if the entity requires normal 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). This is the flag that
+-- the back end should check to determine whether or not to generate
+-- debugging information for an entity. Note that callers should always
+-- use Sem_Util.Set_Debug_Info_Needed, rather than Set_Needs_Debug_Info,
+-- so that the flag is set properly on subsidiary entities.
+
+-- 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.
+--
+-- Never_Set_In_Source (Flag115)
+-- Present in all entities, but can be set only for variables and
+-- parameters. This flag is set if the object is never assigned a value
+-- in user source code, either by assignment or by being used as an out
+-- or in out parameter. Note that this flag is not reset from using an
+-- initial value, so if you want to test for this case as well, test the
+-- Has_Initial_Value flag also.
+--
+-- 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 partially initialized record). The code
+-- generator should instead use the flag Is_True_Constant.
+--
+-- For the purposes of this warning, the default assignment of
+-- access variables to null is not considered the assignment of
+-- of a value (so the warning can be given for code that relies
+-- on this initial null value, when no other value is ever set).
+--
+-- 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 set 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_Never_Set_In_Source 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_Component_Or_Discriminant (synthesized)
+-- Similar to Next_Component, but includes components and discriminants
+-- so the input can have either E_Component or E_Discriminant, and the
+-- same is true for the result. Returns Empty if no more components or
+-- discriminants in the record.
+
+-- 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.
+
+-- Next_Tag_Component (synthesized)
+-- Applies to components of tagged record types. Given a _Tag field
+-- of a record, returns the next _Tag field in this record.
+
+-- Non_Binary_Modulus (Flag58) [base type only]
+-- Present in all subtype and type entities. Set for modular integer
+-- types if the modulus value is other than a power of 2.
+
+-- Non_Limited_View (Node17)
+-- Present in incomplete types that are the shadow entities created
+-- when analyzing a limited_with_clause (Ada 2005: AI-50217). Points to
+-- the defining entity in the original declaration.
+
+-- 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 or free
+-- an instance of such an access type. This is set only in the root
+-- type, since derived types must have the same pool.
+
+-- No_Return (Flag113)
+-- Present in all entities. Always false except in the case of procedures
+-- and generic procedures for which a pragma No_Return is given.
+
+-- 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.
+-- Set to No_Uint if no first bit position is assigned yet.
+
+-- Normalized_Position (Uint14)
+-- 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).
+
+-- No_Strict_Aliasing (Flag136) [base type only]
+-- Present in access types. Set to direct the back end to avoid any
+-- optimizations based on an assumption about the aliasing status of
+-- objects designated by the access type. For the case of the gcc
+-- back end, the effect is as though all references to objects of
+-- the type were compiled with -fno-strict-aliasing. This flag is
+-- set if an unchecked conversion with the access type as a target
+-- type occurs in the same source unit as the declaration of the
+-- access type, or if an explicit pragma No_Strict_Aliasing applies.
+
+-- 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.
+
+-- Optimize_Alignment_Space (Flag241)
+-- A flag present in type, subtype, variable, and constant entities. This
+-- flag records that the type or object is to be layed out in a manner
+-- consistent with Optimize_Alignment (Space) mode. The compiler and
+-- binder ensure a consistent view of any given type or object. If pragma
+-- Optimize_Alignment (Off) mode applies to the type/object, then neither
+-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
+
+-- Optimize_Alignment_Time (Flag242)
+-- A flag present in type, subtype, variable, and constant entities. This
+-- flag records that the type or object is to be layed out in a manner
+-- consistent with Optimize_Alignment (Time) mode. The compiler and
+-- binder ensure a consistent view of any given type or object. If pragma
+-- Optimize_Alignment (Off) mode applies to the type/object, then neither
+-- of the flags Optimize_Alignment_Space/Optimize_Alignment_Time is set.
+
+-- Original_Array_Type (Node21)
+-- Present in modular types and array types and subtypes. Set only
+-- if the Is_Packed_Array_Type flag is set, indicating that the type
+-- is the implementation type for a packed array, and in this case it
+-- points to the original array type for which this is the packed
+-- array implementation type.
+
+-- OK_To_Reorder_Components (Flag239) [base type only]
+-- Present in record types. Set if the back end is permitted to reorder
+-- the components. If not set, the record must be layed out in the order
+-- in which the components are declared textually. Currently this flag
+-- can only be set by debug switches.
+
+-- 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.
+
+-- Overlays_Constant (Flag243)
+-- Present in all entities. Set only for a variable for which there is
+-- an address clause which causes the variable to overlay a constant.
+
+-- Overridden_Operation (Node26)
+-- Present in subprograms. For overriding operations, points to the
+-- user-defined parent subprogram that is being overridden.
+
+-- Package_Instantiation (Node26)
+-- Present in packages and generic packages. When present, this field
+-- references an N_Package_Instantiation node associated with an
+-- instantiated package. In the case where the referenced node has
+-- been rewritten to an N_Package_Specification, the instantiation
+-- node is available from the Original_Node field of the package spec
+-- node. This is currently not guaranteed to be set in all cases, but
+-- when set, the field is used in Get_Package_Instantiation_Node as
+-- one of the means of obtaining the instantiation node. Eventually
+-- it should be set in all cases, including package entities associated
+-- with formal packages. ???
+
+-- 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.
+
+-- 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).
+
+-- Prival (Node17)
+-- Present in private components of protected types. Refers to the entity
+-- of the component renaming declaration generated inside protected
+-- subprograms, entries or barrier functions.
+
+-- Prival_Link (Node20)
+-- Present in constants and variables which rename private components of
+-- protected types. Set to the original private component.
+
+-- 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.
+
+-- 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.
+
+-- Protection_Object (Node23)
+-- Applies to protected entries, entry families and subprograms. Denotes
+-- the entity which is used to rename the _object component of protected
+-- types.
+
+-- 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, except for
+-- the case of an appearance of a simple variable that is not a renaming
+-- as the left side of an assignment in which case Referenced_As_LHS is
+-- set instead, or a similar appearance as an out parameter actual, in
+-- which case As_Out_Parameter_Parameter is set.
+
+-- Referenced_As_LHS (Flag36):
+-- Present in all entities. This flag is set instead of Referenced if a
+-- simple variable that is not a renaming appears as the left side of an
+-- assignment. The reason we distinguish this kind of reference is that
+-- we have a separate warning for variables that are only assigned and
+-- never read.
+
+-- Referenced_As_Out_Parameter (Flag227):
+-- Present in all entities. This flag is set instead of Referenced if a
+-- simple variable that is not a renaming appears as an actual for an out
+-- formal. The reason we distinguish this kind of reference is that
+-- we have a separate warning for variables that are only assigned and
+-- never read, and out parameters are a special case.
+
+-- 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.
+
+-- Related_Type (Node26)
+-- Present in components and constants associated with dispatch tables.
+-- Set to point to the entity of the associated tagged type or interface
+-- type.
+
+-- Relative_Deadline_Variable (Node26) [implementation base type only]
+-- Present in task type entities. This flag is set if a valid and
+-- effective pragma Relative_Deadline applies to the base type. Points
+-- to the entity for a variable that is created to hold the value given
+-- in a Relative_Deadline pragma for a task type.
+
+-- Renamed_Entity (Node18)
+-- Present in exceptions, packages, subprograms and generic units. Set
+-- for entities that are defined by a renaming declaration. Denotes the
+-- renamed entity, or transitively the ultimate renamed entity if
+-- there is a chain of renaming declarations. Empty if no renaming.
+
+-- Renamed_In_Spec (Flag231)
+
+-- Present in package entities. If a package renaming occurs within
+-- a package spec, then this flag is set on the renamed package. The
+-- purpose is to prevent a warning about unused entities in the renamed
+-- package. Such a warning would be inappropriate since clients of the
+-- package can see the entities in the package via the renaming.
+
+-- Renamed_Object (Node18)
+-- Present in all objects (constants, variables, components, formal
+-- parameters, generic formal parameters, and loop parameters).
+-- ??? Present in discriminants?
+-- 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. For formals of a task entry, it denotes the local renaming
+-- that replaces the actual within the accept statement. The field is
+-- Empty otherwise (it is always empty for loop parameters).
+
+-- 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.
+
+-- Requires_Overriding (Flag213)
+-- Present in all subprograms and entries. Set for subprograms that
+-- require overriding as defined by RM-2005-3.9.3(6/2). Note that this
+-- is True only for implicitly declare subprograms; it is not set on the
+-- parent type's subprogram. See also Is_Abstract_Subprogram.
+
+-- 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.
+
+-- Return_Applies_To (Node8)
+-- Present in E_Return_Statement. Points to the entity representing
+-- the construct to which the return statement applies, as defined in
+-- RM-6.5(4/2). Note that a (simple) return statement within an
+-- extended_return_statement applies to the extended_return_statement,
+-- even though it causes the whole function to return.
+
+-- Returns_By_Ref (Flag90)
+-- Present in function entities, to indicate that the function
+-- returns the result by reference, either because its return type is a
+-- by-reference-type or because it uses explicitly the secondary stack.
+
+-- Reverse_Bit_Order (Flag164) [base type only]
+-- Present in all record type entities. Set if a valid pragma an
+-- attribute representation 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 (Ada 95) or a single machine scalar (see Ada 2005
+-- AI-133), or must occupy in integral number of storage units.
+
+-- 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 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 ultimate 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. Note that for a child package,
+-- the Scope will be the parent package, and for a non-child package,
+-- the Scope will be Standard.
+
+-- Scope_Depth (synthesized)
+-- 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_Procs_Instance (Node22)
+-- Present in variables. Set non-Empty only if Is_Shared_Passive is
+-- set, in which case this is the entity for the associated instance of
+-- System.Shared_Storage.Shared_Var_Procs. See Exp_Smem for full details.
+
+-- Size_Check_Code (Node19)
+-- Present in constants and variables. Normally Empty. Set if code is
+-- generated to check the size of the object. 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.
+
+-- Spec_PPC_List (Node24)
+-- Present in subprogram and generic subprogram entities. Points to a
+-- list of Precondition and Postcondition pragma nodes for preconditions
+-- and postconditions declared in the spec. The last pragma encountered
+-- is at the head of this list, so it is in reverse order of textual
+-- appearance.
+
+-- 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).
+
+-- Static_Elaboration_Desired (Flag77)
+-- Present in library-level packages. Set by the pragma of the same
+-- name, to indicate that static initialization must be attempted for
+-- all types declared in the package, and that a warning must be emitted
+-- for those types to which static initialization is not available.
+
+-- Static_Initialization (Node26)
+-- Present in initialization procedures for types whose objects can be
+-- initialized statically. The value of this attribute is a positional
+-- aggregate whose components are compile-time static values. Used
+-- when available in object declarations to eliminate the call to the
+-- initialization procedure, and to minimize elaboration code.
+
+-- Stored_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
+-- stored discriminants for the record (sub)type.
+
+-- 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_Elaboration_Warnings (Flag148)
+-- Present in all entities, can be set only for subprogram entities and
+-- for variables. If this flag is set then Sem_Elab will not generate
+-- elaboration warnings for the subprogram or variable. Suppression of
+-- such warnings is automatic for subprograms for which elaboration
+-- checks are suppressed (without the need to set this flag), but the
+-- flag is also set for various internal entities (such as init procs)
+-- which are known not to generate any possible access before
+-- elaboration, and it is set on variables when a warning is given to
+-- avoid multiple elaboration warnings for the same variable.
+
+-- 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_Style_Checks (Flag165)
+-- Present in all entities. Suppresses any style checks specifically
+-- associated with the given entity if set.
+
+-- Suppress_Value_Tracking_On_Call (Flag217)
+-- Present in all entities. Set in a scope entity if value tracking is to
+-- be suppressed on any call within the scope. Used when an access to a
+-- local subprogram is computed, to deal with the possibility that this
+-- value may be passed around, and if used, may clobber a local variable.
+
+-- Task_Body_Procedure (Node25)
+-- Present in task types and subtypes. Points to the entity for
+-- the task body procedure (as further described in Exp_Ch9, task
+-- bodies are expanded into procedures). A convenient function to
+-- retrieve this field is Sem_Util.Get_Task_Body_Procedure.
+-- The last sentence is odd ??? Why not have Task_Body_Procedure
+-- go to the Underlying_Type of the Root_Type???
+
+-- Treat_As_Volatile (Flag41)
+-- Present in all type entities, and also in constants, components and
+-- variables. Set if this entity is to be treated as volatile for code
+-- generation purposes. Always set if Is_Volatile is set, but can also
+-- be set as a result of situations (such as address overlays) where
+-- the front end wishes to force volatile handling to inhibit aliasing
+-- optimization which might be legally ok, but is undesirable. Note
+-- that the back end always tests this flag rather than Is_Volatile.
+-- The front end tests Is_Volatile if it is concerned with legality
+-- checks associated with declared volatile variables, but if the test
+-- is for the purposes of suppressing optimizations, then the front
+-- end should test Treat_As_Volatile rather than Is_Volatile.
+--
+-- Note: before testing Treat_As_Volatile, consider whether it would
+-- be more appropriate to use Exp_Util.Is_Volatile_Reference instead,
+-- which catches more cases of volatile references.
+
+-- 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 literal for a
+-- base type, but may be an expression in the case of 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 literal for a
+-- base type, but may be an expression in the case of 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 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.
+
+-- Universal_Aliasing (Flag216) [base type only]
+-- Present in all type entities. Set to direct the back-end to avoid
+-- any optimizations based on type-based alias analysis for this type.
+-- Indicates that objects of this type can alias objects of any other
+-- types, which guarantees that any objects can be referenced through
+-- access types designating this type safely, whatever the actual type
+-- of these objects. In other words, the effect is as though access
+-- types designating this type were subject to No_Strict_Aliasing.
+
+-- 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).
+
+-- Used_As_Generic_Actual (Flag222)
+-- Present in all entities, set if the entity is used as an argument to
+-- a generic instantiation. Used to tune certain warning messages.
+
+-- 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 and subtype 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. Note that
+-- clients should generally not test this flag directly, but instead
+-- use function Has_Warnings_Off.
+
+-- Warnings_Off_Used (Flag236)
+-- Present in all entities. Can only be set if Warnings_Off is set. If
+-- set indicates that a warning was suppressed by the Warnings_Off flag,
+-- and Unmodified/Unreferenced would not have suppressed the warning.
+
+-- Warnings_Off_Used_Unmodified (Flag237)
+-- Present in all entities. Can only be set if Warnings_Off is set and
+-- Has_Pragma_Unmodified is not set. If set indicates that a warning was
+-- suppressed by the Warnings_Off status but that pragma Unmodified
+-- would also have suppressed the warning.
+
+-- Warnings_Off_Used_Unreferenced (Flag238)
+-- Present in all entities. Can only be set if Warnings_Off is set and
+-- Has_Pragma_Unreferenced is not set. If set indicates that a warning
+-- was suppressed by the Warnings_Off status but that pragma Unreferenced
+-- would also have suppressed the warning.
+
+-- Was_Hidden (Flag196)
+-- Present in all entities. Used to save the value of the Is_Hidden
+-- attribute when the limited-view is installed (Ada 2005: AI-217).
+
+-- Wrapped_Entity (Node27)
+-- Present in functions and procedures which have been classified as
+-- Is_Primitive_Wrapper. Set to the entity being wrapper.
+
+ ------------------
+ -- Access Kinds --
+ ------------------
+
+ -- The following entity kinds are introduced by the corresponding type
+ -- definitions:
+
+ -- E_Access_Type,
+ -- E_General_Access_Type,
+ -- E_Access_Subprogram_Type,
+ -- E_Anonymous_Access_Subprogram_Type,
+ -- E_Access_Protected_Subprogram_Type,
+ -- E_Anonymous_Access_Protected_Subprogram_Type
+ -- E_Anonymous_Access_Type.
+
+ -- E_Access_Subtype is for an access subtype created by a subtype
+ -- declaration.
+
+ -- 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).

+ -- extended_return_statement on the scope stack.
+
+ 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).

+ -- 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 alignment 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
+ -- 2. At the scope level.
+ -- 3. At the entity level.
+
+ -- See spec of Sem in sem.ads for details of the data structures used
+ -- to keep track of these various methods for suppressing checks.
+
+ -------------------------------
+ -- 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, Task_Info and Relative_Deadline
+ -- 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 analyzed, semantic processing
+ -- creates the entities for the discriminants. It also creates additional
+ -- sets 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:
+
+ -- discr_nameD : constant discr_type renames _task.discr_name;
+
+ -- where discr_nameD 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
+ -- 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.
+
+ ---------------------------------------------------
+ -- Handling of private data in protected objects --
+ ---------------------------------------------------
+
+ -- Private components in protected types pose problems similar to those
+ -- of discriminants. Private data is visible and can be directly referenced
+ -- from protected bodies. However, when protected entries and subprograms
+ -- are expanded into corresponding bodies and barrier functions, private
+ -- components lose their original context and visibility.
+
+ -- To remedy this side effect of expansion, private components are expanded
+ -- into renamings called "privals", by analogy with "discriminals".
+
+ -- private_comp : comp_type renames _object.private_comp;
+
+ -- Prival declarations are inserted during the analysis of subprogram and
+ -- entry bodies to ensure proper visibility for any subsequent expansion.
+ -- _Object is the formal parameter of the generated corresponding body or
+ -- a local renaming which denotes the protected object obtained from entry
+ -- parameter _O. Privals receive minimal decoration upon creation and are
+ -- categorized as either E_Variable for the general case or E_Constant when
+ -- they appear in functions.
+
+ -- Along with the local declarations, each private component carries a
+ -- placeholder which references the prival entity in the current body. This
+ -- form of indirection is used to resolve name clashes of privals and other
+ -- locally visible entities such as parameters, local objects, entry family
+ -- indexes or identifiers used in the barrier condition.
+
+ -- When analyzing the statements of a protected subprogram or entry, any
+ -- reference to a private component must resolve to the locally declared
+ -- prival through normal visibility. In case of name conflicts (the cases
+ -- above), the prival is marked as hidden and acts as a weakly declared
+ -- entity. As a result, the reference points to the correct entity. When a
+ -- private component is denoted by an expanded name (prot_type.comp for
+ -- example), the expansion mechanism uses the placeholder of the component
+ -- to correct the Entity and Etype of the reference.
+
+ -------------------
+ -- Type Synonyms --
+ -------------------
+
+ -- The following type synonyms are used to tidy up the function and
+ -- procedure declarations that follow, and also to make it possible to meet
+ -- the requirement for the XEINFO utility that all function specs must fit
+ -- on a single source line.
+
+ subtype B is Boolean;
+ subtype C is Component_Alignment_Kind;
+ subtype E is Entity_Id;
+ subtype M is Mechanism_Type;

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