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-2.c | 50 +++++++++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 libgomp/testsuite/libgomp.c/reduction-2.c (limited to 'libgomp/testsuite/libgomp.c/reduction-2.c') diff --git a/libgomp/testsuite/libgomp.c/reduction-2.c b/libgomp/testsuite/libgomp.c/reduction-2.c new file mode 100644 index 000000000..52b3faff7 --- /dev/null +++ b/libgomp/testsuite/libgomp.c/reduction-2.c @@ -0,0 +1,50 @@ +#include +#include + +int +main (void) +{ + int i = 0, j = 0, k = ~0, l; + double d = 1.0; +#pragma omp parallel num_threads(4) + { +#pragma omp single + { + i = 16; + k ^= (1 << 16); + d += 32.0; + } + +#pragma omp for reduction(+:i) reduction(*:d) reduction(&:k) + for (l = 0; l < 4; l++) + { + if (omp_get_num_threads () == 4 && (i != 0 || d != 1.0 || k != ~0)) +#pragma omp atomic + j |= 1; + + if (l == omp_get_thread_num ()) + { + i = omp_get_thread_num (); + d = i + 1; + k = ~(1 << (2 * i)); + } + } + + if (omp_get_num_threads () == 4) + { + if (i != (16 + 0 + 1 + 2 + 3)) +#pragma omp atomic + j |= 2; + if (d != (33.0 * 1.0 * 2.0 * 3.0 * 4.0)) +#pragma omp atomic + j |= 4; + if (k != (~0 ^ 0x55 ^ (1 << 16))) +#pragma omp atomic + j |= 8; + } + } + + if (j) + abort (); + return 0; +} -- cgit v1.2.3
