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/cb/cb41001.a | 213 +++++++++++++++++++++++++++++ 1 file changed, 213 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cb/cb41001.a (limited to 'gcc/testsuite/ada/acats/tests/cb/cb41001.a') diff --git a/gcc/testsuite/ada/acats/tests/cb/cb41001.a b/gcc/testsuite/ada/acats/tests/cb/cb41001.a new file mode 100644 index 000000000..95ad868fe --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cb/cb41001.a @@ -0,0 +1,213 @@ +-- CB41001.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).

This result is used as an input parameter to the procedure +-- Raise_Exception.
