--
-- 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
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
--
--
-- Check that the unspecified Size of static discrete
-- subtypes is the number of bits needed to represent each value
-- belonging to the subtype using an unbiased representation, where
-- space for a sign bit is provided only in the event the subtype
-- contains negative values. Check that for first subtypes specified
-- Sizes are supported reflecting this representation. [ARM 95 13.3(55)].
--
-- TEST DESCRIPTION:
-- This test defines a few types that should have distinctly recognizable
-- sizes. A packed record which should result in very specific bits
-- sizes for it's components is used to check the first part of the
-- objective. The second part of the objective is checked by giving
-- sizes for a similar set of types.
--
-- 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
-- 06 MAY 96 SAIC Revised for 2.1
-- 26 FEB 97 PWB.CTA Added pragma Pack for type Check_Record
-- 16 FEB 98 EDS Modified Documentation.
-- 06 JUL 99 RLB Repaired comments, removed junk test cases.
-- Added test cases to test that appropriate Size
-- clauses are allowed.
