-- 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

-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED

-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that for packed records the components are packed as tightly
-- as possible subject to the Size of the component subtypes.
-- Specifically check that Boolean objects are packed one to a bit.
--
-- Check that the Component_Size for a packed array type is less than
-- or equal to the smallest of those factors of the word size that are
-- greater than or equal to the Size of the component subtype.
--
-- TEST DESCRIPTION:
-- This test defines and packs several types, and checks that the sizes
-- of the resulting objects is as expected.
--
-- APPLICABILITY CRITERIA:
-- All implementations must attempt to compile this test.
--
-- For implementations validating against Systems Programming Annex (C):
-- this test must execute and report PASSED.
--
-- For implementations not validating against Annex C:
-- this test may report compile time errors at one or more points
-- indicated by "-- ANX-C RQMT", in which case it may be graded as
-- inapplicable. Otherwise, the test must execute and report PASSED.
--
--
-- CHANGE HISTORY:
-- 22 JUL 95 SAIC Initial version
-- 08 MAY 96 SAIC Strengthened for 2.1
-- 29 JAN 98 EDS Deleted check that Component_Size is really a
-- factor of Word_Size.
