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++/ctor-9.C | 60 ++++++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 libgomp/testsuite/libgomp.c++/ctor-9.C (limited to 'libgomp/testsuite/libgomp.c++/ctor-9.C') diff --git a/libgomp/testsuite/libgomp.c++/ctor-9.C b/libgomp/testsuite/libgomp.c++/ctor-9.C new file mode 100644 index 000000000..215a901f8 --- /dev/null +++ b/libgomp/testsuite/libgomp.c++/ctor-9.C @@ -0,0 +1,60 @@ +// { dg-do run } +// { dg-require-effective-target tls_runtime } + +#include +#include + +#define N 10 +#define THR 4 + +struct B +{ + B& operator=(const B &); +}; + +static B *base; +static B *threadbase; +static int singlethread; +#pragma omp threadprivate(threadbase) + +static unsigned cmask[THR]; + +B& B::operator= (const B &b) +{ + unsigned sindex = &b - base; + unsigned tindex = this - threadbase; + assert(sindex < N); + assert(sindex == tindex); + cmask[omp_get_thread_num ()] |= 1u << tindex; + return *this; +} + +void foo() +{ + #pragma omp parallel + { + B b[N]; + threadbase = b; + #pragma omp single copyprivate(b) + { + assert(omp_get_num_threads () == THR); + singlethread = omp_get_thread_num (); + base = b; + } + } +} + +int main() +{ + omp_set_dynamic (0); + omp_set_num_threads (THR); + foo(); + + for (int i = 0; i < THR; ++i) + if (i == singlethread) + assert(cmask[singlethread] == 0); + else + assert(cmask[i] == (1u << N) - 1); + + return 0; +} -- cgit v1.2.3
