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/ca/ca11013.a | 201 +++++++++++++++++++++++++++++ 1 file changed, 201 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/ca/ca11013.a (limited to 'gcc/testsuite/ada/acats/tests/ca/ca11013.a') diff --git a/gcc/testsuite/ada/acats/tests/ca/ca11013.a b/gcc/testsuite/ada/acats/tests/ca/ca11013.a new file mode 100644 index 000000000..c7f442788 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/ca/ca11013.a @@ -0,0 +1,201 @@ +-- CA11013.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).

Declare a generic child function of this package +-- which builds a random complex number. Declare a second +-- package which defines a random complex number generator. This +-- package provides actual parameters for the generic parent package. +-- +-- Instantiate the first generic package, then instantiate the child +-- generic function as a child unit of the first instance. In the main +-- program, check that the operations in both instances perform as +-- expected. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 16 Nov 95 SAIC Update and repair for ACVC 2.0.1 +-- 19 Oct 96 SAIC ACVC 2.1: Added pragma Elaborate to context +-- clause of CA11013_3. +-- 27 Feb 97 CTA.PWB Added elaboration pragma at package CA11013_3 +--! + +generic -- Complex number abstraction. + type Real_Type is digits <>; + with function Random_Generator (Seed : Real_Type) return Real_Type; + +package CA11013_0 is + + -- Simulate a generic complex number support package.
