-- OBJECTIVE:
-- Check that a Size clause for an object is supported if the specified
-- size is at least as large as the subtype's size, and correspond to a
-- size in storage elements that is a multiple of the object's (non-zero)
-- Alignment. RM 13.3(43)
--
-- TEST DESCRIPTION:
-- This test defines several types and then asserts specific sizes for
-- the, it then checks that the size set is reported back.
--
-- 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 Corrected and strengthened for 2.1
-- 14 FEB 97 PWB.CTA Changed 'Size specifications to multiples
-- of System.Storage_Unit; restricted 'Size spec
-- for enumeration object to max integer size.
-- 16 FEB 98 EDS Modify Documentation.
-- 25 JAN 99 RLB Repaired to properly set and check sizes.
-- 29 JAN 99 RLB Added Pack pragma needed for some implementations.
-- Corrected to support a Storage_Unit size < 8.
