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/cc/cc51004.a | 181 +++++++++++++++++++++++++++++ 1 file changed, 181 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cc/cc51004.a (limited to 'gcc/testsuite/ada/acats/tests/cc/cc51004.a') diff --git a/gcc/testsuite/ada/acats/tests/cc/cc51004.a b/gcc/testsuite/ada/acats/tests/cc/cc51004.a new file mode 100644 index 000000000..09b1b57fa --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cc/cc51004.a @@ -0,0 +1,181 @@ +-- CC51004.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 +-- library-level generic subprogram with a formal derived type using the +-- tagged type as ancestor. Give the generic subprogram an in out +-- parameter of the formal derived type. Inside the generic, use the +-- discriminant component and modify the remaining components of the +-- tagged parameter. In the main program, declare tagged record objects +-- with two different discriminant values. Derive an indefinite type from +-- the tagged type with a new discriminant part. Instantiate the +-- generic subprogram for the root tagged subtype and the derived subtype. +-- Call the root subtype instance with actual parameters having the two +-- discriminant values. Also call the derived subtype instance with an +-- appropriate actual. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 05 Jan 94 SAIC Removed unknown discriminant part from formal +-- derived type.
