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. +-- +--! + +with Report;
