+-- Delayed Freezing and Elaboration --
+--------------------------------------
+
+-- The flag Has_Delayed_Freeze indicates that an entity carries an explicit
+-- freeze node, which appears later in the expanded tree.
+
+-- a) The flag is used by the front-end to trigger expansion actions which
+-- include the generation of that freeze node. Typically this happens at the
+-- end of the current compilation unit, or before the first subprogram body is
+-- encountered in the current unit. See files freeze and exp_ch13 for details
+-- on the actions triggered by a freeze node, which include the construction
+-- of initialization procedures and dispatch tables.
+
+-- b) The presence of a freeze node on an entity is used by the backend to
+-- defer elaboration of the entity until its freeze node is seen. In the
+-- absence of an explicit freeze node, an entity is frozen (and elaborated)
+-- at the point of declaration.
+
+-- For object declarations, the flag is set when an address clause for the
+-- object is encountered. Legality checks on the address expression only take
+-- place at the freeze point of the object.
+
+-- Most types have an explicit freeze node, because they cannot be elaborated
+-- until all representation and operational items that apply to them have been
+-- analyzed. Private types and incomplete types have the flag set as well, as
+-- do task and protected types.
+
+-- Implicit base types created for type derivations, as well as classwide
+-- types created for all tagged types, have the flag set.
+
+-- If a subprogram has an access parameter whose designated type is incomplete
+-- the subprogram has the flag set.

-- statements referencing the same entry.
+-- 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.
+
-- 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
-- rather irregular, and the semantic checks that depend on the nominal
-- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv).

-- 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
-- make sure that the address can be meaningfully taken, and also in
-- the case of subprograms to control output of certain warnings.
+-- Aft_Value (synthesized)
+-- Applies to fixed and decimal types. Computes a universal integer
+-- that holds value of the Aft attribute for the type.
+
-- Alias (Node18)
-- Present in overloaded entities (literals, subprograms, entries) and
-- subprograms that cover a primitive operation of an abstract interface
-- 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.
+-- a subprogram renaming, where it points to the renamed subprogram. For
+-- an inherited operation (of a type extension) that is overridden in a
+-- private part, the Alias is the overriding operation. In this fashion a
+-- call from outside the package ends up executing the new body even if
+-- non-dispatching, and a call from inside calls the overriding operation
+-- because it hides the implicit one. Alias is always empty for entries.
-- Alignment (Uint14)
-- Present in entities for types and also in constants, variables
-- 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.
-- 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

+-- parameters that explicily exclude 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
-- Present in all entities. Set if a pragma Suppress or Unsuppress
-- mentions the entity specifically in the second argument. If this

--- tables must be consulted to determine if the is actually an active
+-- tables must be consulted to determine if there actually is an active
-- Suppress or Unsuppress pragma that applies to the entity.
-- Class_Wide_Type (Node9)
-- 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.
+-- Note: Component_Bit_Offset is redundant with respect to the fields
+-- Normalized_First_Bit and Normalized_Position, and could in principle
+-- be eliminated, but it is convenient in several situations, including
+-- use in Gigi, to have this redundant field.
-- 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.
+-- 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
-- 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
-- other function entities, only in implicit inequality routines,
-- where Comes_From_Source is always False.
+-- Corresponding_Protected_Entry (Node18)
+-- Present in subrogram bodies. Set for subprogram bodies that implement
+-- a protected type entry to point to the entity for the entry.
+
-- Corresponding_Record_Type (Node18)
-- Present in protected and task types and subtypes. References the
-- entity for the corresponding record type constructed by the expander
-- 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.
+-- Applies to all entities. Returns the tree node for the construct 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/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. Also note that for subprograms, this
+-- returns the {function,procedure}_specification, not the subprogram_
+-- declaration.
-- Default_Expr_Function (Node21)
-- Present in parameters. It holds the entity of the parameterless
-- Present in floating point types and subtypes and decimal types and
-- subtypes. Contains the Digits value specified in the declaration.
+-- Direct_Primitive_Operations (Elist10)
+-- Present in tagged types and subtypes (including synchronized types),
+-- in tagged private types and in tagged incomplete types. Element list
+-- of entities for primitive operations of the tagged type. Not present
+-- in untagged types. In order to follow the C++ ABI, entities of
+-- primitives that come from source must be stored in this list in the
+-- order of their occurrence in the sources. For incomplete types the
+-- list is always empty.
+
-- 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
-- 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.
+-- index starting at 1 and ranging up to number of 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.
+-- Dispatch_Table_Wrappers (Elist26) [implementation base type only]
+-- Present in record type [with private] entities. Set in library level
+-- record type entities if we are generating statically allocated
+-- dispatch tables. For a tagged type, points to the list of dispatch
+-- table wrappers associated with the tagged type. For a non-tagged
+-- record, contains No_Elist.
-- DTC_Entity (Node16)
-- Present in function and procedure entities. Set to Empty unless
-- 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
-- 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.
+--
+-- Note one obscure case: for pragma Default_Storage_Pool (null), the
+-- Etype of the N_Null node is Empty.
-- Exception_Code (Uint22)
-- Present in exception entitites. Set to zero unless either an
-- 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,
-- 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_Exit_Statement (Node8)
+-- Present in E_Loop entity. The exit statements for a loop are chained
+-- (in reverse order of appearence) using this field to point to the
+-- first entry in the chain (last exit statement in the loop). The
+-- entries are chained through the Next_Exit_Statement field of the
+-- N_Exit_Statement node 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.
-- Alignment attribute definition clause
-- Machine_Attribute pragma
-- Link_Alias pragma
--- Link-Section pragma
+-- Linker_Section pragma
-- Weak_External pragma
--
-- If any of these items are present, then the flag Has_Gigi_Rep_Item
-- 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.
+-- Float_Rep (Uint8)
+-- Present in floating-point entities. Contains a value of type
+-- Float_Rep_Kind. Together with the Digits_Value uniquely defines
+-- the floating-point representation to be used.
-- Freeze_Node (Node7)
-- Present in all entities. If there is an associated freeze node for
-- 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. If an incomplete type E1 is completed by a
+-- private type E2 whose full type declaration entity is E3 then the
+-- full view of E1 is E2, and the full view of E2 is E3. See also
+-- Underlying_Type.
-- Generic_Homonym (Node11)
-- Present in generic packages. The generic homonym is the entity of
-- 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_Aspects (Flag200) Present in all entities. Set true if the
+-- Rep_Item chain for the entity has one or more N_Aspect_Definition
+-- nodes chained which are not to be evaluated till the freeze point.
+-- The aspect definition expression clause has been preanalyzed to get
+-- visibility at the point of use, but no other action has been taken.
+
-- 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
-- definition contains at least one procedure to which a pragma
-- Interrupt_Handler applies.
+-- Has_Invariants (Flag232)
+-- Present in all type entities and in subprogram entities. Set True in
+-- private types if an Invariant or Invariant'Class aspect applies to the
+-- type, or if the type inherits one or more Invariant'Class aspects.
+-- Also set in the corresponding full type. Note: if this flag is set
+-- True, then usually the Invariant_Procedure attribute is set once the
+-- type is frozen, however this may not be true in some error situations.
+-- Note that it might be the full type which has inheritable invariants,
+-- and then the flag will also be set in the private type. Also set in
+-- the invariant procedure entity, to distinguish it among entries in the
+-- Subprograms_For_Type.
+
+-- Has_Inheritable_Invariants (Flag248)
+-- Present in all type entities. Set True in private types from which one
+-- or more Invariant'Class aspects will be inherited if a another type is
+-- derived from the type (i.e. those types which have an Invariant'Class
+-- aspect, or which inherit one or more Invariant'Class aspects). Also
+-- set in the corresponding full types. Note that it might be the full
+-- type which has inheritable invariants, and in this case the flag will
+-- also be set in the private type.
+
-- 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
-- pragma Inline_Always applies. Note that if this flag is set, the flag
-- Has_Pragma_Inline is also set.
+-- Has_Pragma_Ordered (Flag198) [implementation base type only]
+-- Present in entities for enumeration types. If set indicates that a
+-- valid pragma Ordered was given for the type. This flag is inherited
+-- by derived enumeration types. We don't need to distinguish the derived
+-- case since we allow multiple occurrences of this pragma anyway.
+
-- 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
-- (but unlike the case with pragma Unreferenced, it is ok to reference
-- such an object and no warning is generated.
+-- Has_Predicates (Flag250)
+-- Present in all entities. Set in type and subtype entities if a pragma
+-- Predicate or Predicate aspect applies to the type, or if it inherits a
+-- Predicate aspect from its parent or progenitor types. Also set in the
+-- predicate function entity, to distinguish it among entries in the
+-- Subprograms_For_Type.
+
-- Has_Primitive_Operations (Flag120) [base type only]
-- Present in all type entities. Set if at least one primitive operation
-- is defined for the type.
-- 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.
+-- Used for semantic checks in E.4(18) and elsewhere.
-- Has_Qualified_Name (Flag161)

-- In_Package_Body (Flag48)
-- Present in package entities. Set on the entity that denotes the
-- package (the defining occurrence of the package declaration) while
-- 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).
+
+-- Invariant_Procedure (synthesized)
+-- Present in types and subtypes. Set for private types if one or more
+-- Invariant, or Invariant'Class, or inherited Invariant'Class aspects
+-- apply to the type. Points to the entity for a procedure which checks
+-- the invariant. This invariant procedure takes a single argument of the
+-- given type, and returns if the invariant holds, or raises exception
+-- Assertion_Error with an appropriate message if it does not hold. This
+-- attribute is present but always empty for private subtypes. This
+-- attribute is also set for the corresponding full type.
--
+-- Note: the reason this is marked as a synthesized attribute is that the
+-- way this is stored is as an element of the Subprograms_For_Type field.

+-- Present only in entities for variables. If this flag is set, it
