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/reduction-4.c | 36 +++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 libgomp/testsuite/libgomp.c/reduction-4.c (limited to 'libgomp/testsuite/libgomp.c/reduction-4.c') diff --git a/libgomp/testsuite/libgomp.c/reduction-4.c b/libgomp/testsuite/libgomp.c/reduction-4.c new file mode 100644 index 000000000..23e9d6d5b --- /dev/null +++ b/libgomp/testsuite/libgomp.c/reduction-4.c @@ -0,0 +1,36 @@ +#include +#include + +int +main (void) +{ + int i = 0, j = 0, k = 0, l = 0; +#pragma omp parallel num_threads(4) reduction(-:i) reduction(|:k) \ + reduction(^:l) + { + if (i != 0 || k != 0 || l != 0) +#pragma omp atomic + j |= 1; + + if (omp_get_num_threads () != 4) +#pragma omp atomic + j |= 2; + + i = omp_get_thread_num (); + k = 1 << (2 * i); + l = 0xea << (3 * i); + } + + if (j & 1) + abort (); + if ((j & 2) == 0) + { + if (i != (0 + 1 + 2 + 3)) + abort (); + if (k != 0x55) + abort (); + if (l != 0x1e93a) + abort (); + } + return 0; +} -- cgit v1.2.3
