+-- 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 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)

+-- a subprogram renaming, where it points to the renamed subprogram. For
+-- an inherited operation (of a type extension) that is overridden in a

+-- 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)

-- Has_Pragma_Pack (Flag121) [implementation base type only]

-- Storage_Size_Variable (Node15) [implementation base type only]

-- 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.
+-- Subprograms_For_Type (Node29)
+-- Present in all type entities, and in subprogram entities. This is used
+-- to hold a list of subprogram entities for subprograms associated with
+-- the type, linked through the Subprogram_List field of the subprogram
+-- entity. Basically this is a way of multiplexing the single field to
+-- hold more than one entity (since we ran out of space in some type

--- Vax_Float (Flag151) [base type only]
--- Present in all type and subtype entities. Set only on the base type of

-- E_Access_Subtype is for an access subtype created by a subtype
-- declaration.
- -- In addition, we define the kind E_Allocator_Type to label
