obtained gcc-4.6.4.tar.bz2 from upstream website;upstream
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.

A third decimal +-- fixed point type C is declared with digits and delta values different +-- from those of A and B. For type A (and B), checks are performed +-- on the following operations, where one operand type is C, and the +-- other operand type and the result type is A (or B): +-- +-- - 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: +-- 22 Mar 96 SAIC Prerelease version for ACVC 2.1. +-- +--! + +generic + type Decimal_Fixed_1 is delta <> digits <>; + type Decimal_Fixed_2 is delta <> digits <>; +package CXF2003_0 is + + procedure Multiply_And_Truncate (Balance : in out Decimal_Fixed_1; + Factor : in Decimal_Fixed_2); + + procedure Divide_And_Truncate (Balance : in out Decimal_Fixed_1; + Divisor : in Decimal_Fixed_2); + + procedure Multiply_And_Round (Balance : in out Decimal_Fixed_1; + Factor : in Decimal_Fixed_2); + + procedure Divide_And_Round (Balance : in out Decimal_Fixed_1; + Divisor : in Decimal_Fixed_2); + +end CXF2003_0; + + + --==================================================================-- + + +package body CXF2003_0 is + + procedure Multiply_And_Truncate (Balance : in out Decimal_Fixed_1; + Factor : in Decimal_Fixed_2) is + Interest : Decimal_Fixed_1; + begin + Interest := Factor * Balance; -- Fixed-fixed multiplication. + Balance := Balance + Interest; + end Multiply_And_Truncate; + + + procedure Divide_And_Truncate (Balance : in out Decimal_Fixed_1; + Divisor : in Decimal_Fixed_2) is + Interest : Decimal_Fixed_1; + begin + Interest := Balance / Divisor; -- Fixed-fixed division. + Balance := Balance + Interest; + end Divide_And_Truncate; + + + procedure Multiply_And_Round (Balance : in out Decimal_Fixed_1; + Factor : in Decimal_Fixed_2) is + Interest : Decimal_Fixed_1; + begin + -- Fixed-fixed multiplication. + Interest := Decimal_Fixed_1'Round ( Factor * Balance ); + Balance := Balance + Interest; + end Multiply_And_Round; + + + procedure Divide_And_Round (Balance : in out Decimal_Fixed_1; + Divisor : in Decimal_Fixed_2) is + Interest : Decimal_Fixed_1; + begin + -- Fixed-fixed division. + Interest := Decimal_Fixed_1'Round ( Balance / Divisor ); + Balance := Balance + Interest; + end Divide_And_Round; + +end CXF2003_0; + + + --==================================================================-- + + +package CXF2003_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 + + + type Interest_Rate is delta 0.00001 digits 9; -- range -9999.99999 .. + -- +9999.99999 + +end CXF2003_1; + + + --==================================================================-- + + +with CXF2003_0; +with CXF2003_1; + +with Report; +procedure CXF2003 is + + Loop_Count : constant := 1825; + type Loop_Range is range 1 ..
