2015-01-21tsan: remove sleeps from testsDmitry Vyukov
Even sleep(1) lead to episodical flakes on some machines. Use an invisible by tsan barrier to enforce required execution order instead. This makes the tests deterministic and faster. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@226659 91177308-0d34-0410-b5e6-96231b3b80d8
2014-05-30tsan: make positive tests more robustDmitry Vyukov
Add a script that is used to deflake inherently flaky tsan tests. It is invoked from lit tests as: %deflake %run %t The script runs the target program up to 10 times, until it produces a tsan warning. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@209898 91177308-0d34-0410-b5e6-96231b3b80d8
