-- 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.

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

--
-- OBJECTIVE:
-- Check that Component_Sizes that are specified via an aspect
-- specification and are multiples of the word size are supported.
--
-- Check that for such Component_Sizes arrays contain no gaps between
-- components.
--
-- TEST DESCRIPTION:
-- This test defines three array types and specifies their layouts
-- using representation specifications for the 'Component_Size and
-- pragma Packs for each. It then checks that the implied assumptions
-- about the resulting layout actually can be made.
--
-- 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:
-- 29 Mar 17 RLB Created test from CD30009.
