-- 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

--
-- OBJECTIVE:
-- Check that subprograms Shift_Left, Shift_Right,
-- Shift_Right_Arithmetic, Rotate_Left, and Rotate_Right are available
-- and produce correct results for values of signed and modular
-- integer types of 8 bits.
--
-- TEST DESCRIPTION:
-- This test uses the shift and rotate functions of package Interfaces
-- with a modular type representative of 8 bits. The functions
-- are used as the right hand of assignment statements, as part of
-- conditional statements, and as arguments in other function calls.
--
-- A check is performed in the test to determine whether the bit
-- ordering method used by the machine/implementation is high-order
-- first ("Big Endian") or low-order first ("Little Endian"). The
-- specific subtests use this information to evaluate the results of
-- each of the functions under test.
--
-- Note: In the string associated with each Report.Failed statement, the
-- acronym BE refers to Big Endian, LE refers to Little Endian.
--
-- APPLICABILITY CRITERIA:
-- This test is applicable to all implementations that support signed
-- and modular integer types of 8 bits.
--
--
-- CHANGE HISTORY:
-- 21 Aug 95 SAIC Initial prerelease version.
-- 07 May 96 SAIC Incorporated reviewer comments for ACVC 2.1.
