* Update more file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | | 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
* [libc++] Remove race condition in std::asyncLouis Dionne2018-08-241-4/+1
| | | | | | | | | | | | | | | | | Summary: The state associated to the future was set in one thread (with synchronization) but read in another thread without synchronization, which led to a data race. https://bugs.llvm.org/show_bug.cgi?id=38181 rdar://problem/42548261 Reviewers: mclow.lists, EricWF Subscribers: christof, dexonsmith, cfe-commits Differential Revision: https://reviews.llvm.org/D51170 llvm-svn: 340608
* Code cleanup - change naked 'throw' expressions to call helpre function ↵Marshall Clow2018-07-301-33/+11
| | | | | | '__throw_future_error'. The behavior change is that if you build libc++ with exceptions disabled, and then use that in a program that sets the value of the future twice (for example), it will now abort instead of behaving unpredictably. llvm-svn: 338332
* Make it possible to build a no-exceptions variant of libcxx.Asiri Rathnayake2015-11-101-0/+2
| | | | | | | | | | | | Fixes a small omission in libcxx that prevents libcxx being built when -DLIBCXX_ENABLE_EXCEPTIONS=0 is specified. This patch adds XFAILS to all those tests that are currently failing on the new -fno-exceptions library variant. Follow-up patches will update the tests (progressively) to cope with the new library variant. Change-Id: I4b801bd8d8e4fe7193df9e55f39f1f393a8ba81a llvm-svn: 252598
* Fix PR23293 - Do not unlock shared state before notifying consumers.Eric Fiselier2015-06-121-5/+0
| | | | | | | | Within the shared state methods do not unlock the lock guards manually. This could cause a race condition where the shared state is destroyed before the method is complete. llvm-svn: 239577
* Allow libc++ to be built on systems without POSIX threadsJonathan Roelofs2014-09-051-0/+6
| | | | | | | | | | If you're crazy enough to want this sort of thing, then add -D_LIBCPP_HAS_NO_THREADS to your CXXFLAGS and --param=additiona_features=libcpp-has-no-threads to your lit commnad line. http://reviews.llvm.org/D3969 llvm-svn: 217271
* Fix GCC unknown pragma warning in libc++.Logan Chien2013-12-141-0/+9
| | | | | | | | | | We should check defined(__clang__) before the usage of the clang diagnostic pragmas. The [-Wswitch] warning in src/future.cpp should be ignored. As the result, the equivalent GCC pragma is added. llvm-svn: 197314

* noexcept for <memory>. I've added a few extension noexcept to: ↵Howard Hinnant2011-05-281-1/+1
| | | | | | allocator_traits<A>::deallocate, allocaate<T>::deallocate, return_temporary_buffer, and default_delete<T>::operator()(T*) const. My rationale was: If a std-dicated noexcept function needs to call another std-defined function, that called function must be noexcept. We're all a little new to noexcept, so things like this are to be expected. Also included fix for broken __is_swappable trait pointed out by Marc Glisse, thanks Marc|. And fixed a test case for is_nothrow_destructible. Destructors are now noexcept by default| llvm-svn: 132261
