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/c4/c455001.a | 164 +++++++++++++++++++++++++++++ 1 file changed, 164 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/c4/c455001.a (limited to 'gcc/testsuite/ada/acats/tests/c4/c455001.a') diff --git a/gcc/testsuite/ada/acats/tests/c4/c455001.a b/gcc/testsuite/ada/acats/tests/c4/c455001.a new file mode 100644 index 000000000..8685e1b33 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/c4/c455001.a @@ -0,0 +1,164 @@ +-- C455001.A + +-- Grant of Unlimited Rights +-- +-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687 and +-- F08630-91-C-0015, the U.S. Government obtained unlimited rights in the +-- software and documentation contained herein.
