Chandler Carruth	57b08b0944	Update more file headers across all of the LLVM projects in the monorepo ... to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648	2019-01-19 10:56:40 +00:00
Eric Fiselier	10967a6ea6	[libcxx] Add Atomic test helper and fix TSAN failures. ... Summary: This patch attempts to fix the last 3 TSAN failures on the libc++ bot (http://lab.llvm.org:8011/builders/libcxx-libcxxabi-x86_64-linux-ubuntu-tsan/builds/143). This patch also adds a `Atomic` test type that can be used where `<atomic>` cannot. `wait.exception.pass.cpp` and `wait_for.exception.pass.cpp` were failing because the test replaced `std::terminate` with `std::exit`. `std::exit` would asynchronously run the TLS and static destructors and this would cause a race condition. See PR22606 and D8802 for more details. This is fixed by using `_Exit` to prevent cleanup. `notify_all_at_thread_exit.pass.cpp` exercises the same race condition but for different reasons. I fixed this test by manually joining the thread before beginning program termination.

Eric Fiselier	9a37bc91d2	Fix race conditions in test class used throughout the std::thread tests. ... The test class 'G' reads and writes to the same static variables in its constructor, destructor and call operator. When threads are constructed using `std::thread t((G()))` there is a race condition between the destruction of the temporary and the execution of `G::operator()()`. The fix is to simply create the input before creating the thread. llvm-svn: 233946	2015-04-02 21:12:17 +00:00
