-- C760012.A
--
-- Grant of Unlimited Rights
--
-- 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
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- 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
-- released technical data and computer software in whole or in part, in
-- any manner and for any purpose whatsoever, and to have or permit others
-- to do so.
--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE

-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that record components that have per-object access discriminant
-- constraints are initialized in the order of their component
-- declarations, and after any components that are not so constrained.
--
-- Check that record components that have per-object access discriminant
-- constraints are finalized in the reverse order of their component
-- declarations, and before any components that are not so constrained.
--
-- TEST DESCRIPTION:
-- The type List_Item is the "container" type. It holds two fields that
-- have per-object access discriminant constraints, and two fields that
-- are not discriminated. These four fields are all controlled types.
-- A fifth field is a pointer used to maintain a linked list of these
-- data objects. Each component is of a unique type which allows for
-- the test to simply track the order of initialization and finalization.
--
-- The types and their purpose are:
-- Constrained_First - a controlled discriminated type
-- Constrained_Second - a controlled discriminated type
-- Simple_First - a controlled type with no discriminant
-- Simple_Second - a controlled type with no discriminant
--
-- The required order of operations:
-- Initialize
-- ( Simple_First | Simple_Second ) -- no "internal order" required
-- Constrained_First
-- Constrained_Second
-- Finalize
-- Constrained_Second
-- Constrained_First
-- ( Simple_First | Simple_Second ) -- must be inverse of init.
--
--
-- CHANGE HISTORY:
-- 23 MAY 95 SAIC Initial version
-- 02 MAY 96 SAIC Reorganized for 2.1
-- 05 DEC 96 SAIC Simplified for 2.1; added init/fin ordering check
-- 31 DEC 97 EDS Remove references to and uses of
-- Initialization_Sequence
