From 341e5bcb45c9aeab3584d0aaa07a814282ebbefc Mon Sep 17 00:00:00 2001 From: Alexey Samsonov Date: Tue, 18 Sep 2012 07:23:54 +0000 Subject: [TSan] port all output tests to lit and move them to lit_tests directory. This makes 'make check-tsan' command test both unit and output TSan tests. Old custom makefiles for running TSan tests are still functional as well. llvm-svn: 164110 --- compiler-rt/lib/tsan/lit_tests/static_init3.cc | 47 ++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 compiler-rt/lib/tsan/lit_tests/static_init3.cc (limited to 'compiler-rt/lib/tsan/lit_tests/static_init3.cc') diff --git a/compiler-rt/lib/tsan/lit_tests/static_init3.cc b/compiler-rt/lib/tsan/lit_tests/static_init3.cc new file mode 100644 index 00000000000..40fd4b940f5 --- /dev/null +++ b/compiler-rt/lib/tsan/lit_tests/static_init3.cc @@ -0,0 +1,47 @@ +// RUN: %clangxx_tsan -O1 %s -o %t && %t 2>&1 | FileCheck %s +#include +#include +#include +#include + +struct Cache { + int x; +}; + +Cache g_cache; + +Cache *CreateCache() { + g_cache.x = rand(); + return &g_cache; +} + +_Atomic(Cache*) queue; + +void *Thread1(void *x) { + static Cache *c = CreateCache(); + __c11_atomic_store(&queue, c, 0); + return 0; +} + +void *Thread2(void *x) { + Cache *c = 0; + for (;;) { + c = __c11_atomic_load(&queue, 0); + if (c) + break; + sched_yield(); + } + if (c->x >= RAND_MAX) + exit(1); + return 0; +} + +int main() { + pthread_t t[2]; + pthread_create(&t[0], 0, Thread1, 0); + pthread_create(&t[1], 0, Thread2, 0); + pthread_join(t[0], 0); + pthread_join(t[1], 0); +} + +// CHECK: WARNING: ThreadSanitizer: data race -- cgit v1.2.3
