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. --- libgomp/testsuite/libgomp.c/omp_workshare4.c | 48 ++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 libgomp/testsuite/libgomp.c/omp_workshare4.c (limited to 'libgomp/testsuite/libgomp.c/omp_workshare4.c') diff --git a/libgomp/testsuite/libgomp.c/omp_workshare4.c b/libgomp/testsuite/libgomp.c/omp_workshare4.c new file mode 100644 index 000000000..67605e38b --- /dev/null +++ b/libgomp/testsuite/libgomp.c/omp_workshare4.c @@ -0,0 +1,48 @@ +/****************************************************************************** +* OpenMP Example - Combined Parallel Loop Work-sharing - C/C++ Version +* FILE: omp_workshare4.c +* DESCRIPTION: +* This is a corrected version of the omp_workshare3.c example.
