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; with Interfaces; with Ada.Exceptions; procedure CXB2001 is begin Report.Test ("CXB2001", "Check that subprograms Shift_Left, Shift_Right, " & "Shift_Right_Arithmetic, Rotate_Left, and Rotate_Right " & "produce correct results for values of signed and " & "modular integer types of 8 bits"); Test_Block: declare use Ada.Exceptions; use Interfaces; TC_Amount : Natural := Natural'First; Big_Endian : Boolean := False; -- Range of type Unsigned_8 is 0..255 (0..Modulus-1).
