-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained

-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the

--*
--
-- OBJECTIVE:
-- Check that the type of an extension aggregate may be derived from the
-- type of the ancestor part through multiple record extensions. Check
-- for ancestor parts that are subtype marks. Check that the type of the
-- ancestor part may be abstract.
--
-- TEST DESCRIPTION:
-- This test defines the following type hierarchies:
--
-- (A) (F)
-- Abstract Abstract
-- Tagged record Tagged private
-- / \ / \
-- / (C) (G) \
-- (B) Abstract Abstract (H)
-- Record private record Private
-- extension extension extension extension
-- | | | |
-- (D) (E) (I) (J)
-- Record Record Record Record
-- extension extension extension extension
--
-- Extension aggregates for B, D, E, I, and J are constructed using each
-- of its ancestor types as the ancestor part (except for E and J, for
-- which only the immediate ancestor is used, since using A and F,
-- respectively, as the ancestor part would be illegal).
--
-- X1 : B := (A with ...);
-- X2 : D := (A with ...); X5 : I := (F with ...);
-- X3 : D := (B with ...); X6 : I := (G with ...);
-- X4 : E := (C with ...); X7 : J := (H with ...);
--
-- For each assignment of an aggregate, the value of the target object is
-- checked to ensure that the proper values for each component were
-- assigned.
