From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/ada/acats/tests/cxf/cxf2002.a | 352 ++++++++++++++++++++++++++++ 1 file changed, 352 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cxf/cxf2002.a (limited to 'gcc/testsuite/ada/acats/tests/cxf/cxf2002.a') diff --git a/gcc/testsuite/ada/acats/tests/cxf/cxf2002.a b/gcc/testsuite/ada/acats/tests/cxf/cxf2002.a new file mode 100644 index 000000000..984daa97b --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cxf/cxf2002.a @@ -0,0 +1,352 @@ +-- CXF2002.A +-- +-- 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).

For each type, checks are +-- performed on the following operations, where the operand and result +-- types are the same: +-- +-- - Multiplication. +-- - Multiplication, where the attribute 'Round is applied to the +-- result. +-- - Division. +-- - Division, where the attribute 'Round is applied to the result. +-- +-- Each operation is performed within a loop, where one operand is +-- always the same variable. After the loop completes, the cumulative +-- total contained in this variable is compared with the expected +-- result. +-- +-- APPLICABILITY CRITERIA: +-- This test is only applicable for a compiler attempting validation +-- for the Information Systems Annex. +-- +-- +-- CHANGE HISTORY: +-- 27 Mar 96 SAIC Prerelease version for ACVC 2.1. +-- +--! + +generic + type Decimal_Fixed is delta <> digits <>; +package CXF2002_0 is + + procedure Multiply_And_Truncate (Balance : in out Decimal_Fixed; + Factor : in Decimal_Fixed); + + procedure Divide_And_Truncate (Balance : in out Decimal_Fixed; + Divisor : in Decimal_Fixed); + + procedure Multiply_And_Round (Balance : in out Decimal_Fixed; + Factor : in Decimal_Fixed); + + procedure Divide_And_Round (Balance : in out Decimal_Fixed; + Divisor : in Decimal_Fixed); + +end CXF2002_0; + + + --==================================================================-- + + +package body CXF2002_0 is + + procedure Multiply_And_Truncate (Balance : in out Decimal_Fixed; + Factor : in Decimal_Fixed) is + Interest : Decimal_Fixed; + begin + Interest := Factor * Balance; -- Fixed-fixed multiplication. + Balance := Balance + Interest; + end Multiply_And_Truncate; + + + procedure Divide_And_Truncate (Balance : in out Decimal_Fixed; + Divisor : in Decimal_Fixed) is + Interest : Decimal_Fixed; + begin + Interest := Balance / Divisor; -- Fixed-fixed division. + Balance := Balance + Interest; + end Divide_And_Truncate; + + + procedure Multiply_And_Round (Balance : in out Decimal_Fixed; + Factor : in Decimal_Fixed) is + Interest : Decimal_Fixed; + begin + -- Fixed-fixed multiplication. + Interest := Decimal_Fixed'Round ( Factor * Balance ); + Balance := Balance + Interest; + end Multiply_And_Round; + + + procedure Divide_And_Round (Balance : in out Decimal_Fixed; + Divisor : in Decimal_Fixed) is + Interest : Decimal_Fixed; + begin + -- Fixed-fixed division. + Interest := Decimal_Fixed'Round ( Balance / Divisor ); + Balance := Balance + Interest; + end Divide_And_Round; + +end CXF2002_0; + + + --==================================================================-- + + +package CXF2002_1 is + + type Money_Radix2 is delta 0.01 digits 11; -- range -999,999,999.99 .. + for Money_Radix2'Machine_Radix use 2; -- +999,999,999.99 + + + type Money_Radix10 is delta 0.01 digits 11; -- range -999,999,999.99 .. + for Money_Radix10'Machine_Radix use 10; -- +999,999,999.99 + +end CXF2002_1; + + + --==================================================================-- + + +with CXF2002_0; +with CXF2002_1; + +with Report; +procedure CXF2002 is + + Loop_Count : constant := 300; + type Loop_Range is range 1 ..
