* Refactor pthread usage of libcxx.Asiri Rathnayake2016-05-061-5/+5
| | | | | | | | | | | | | This patch extracts out all the pthread dependencies of libcxx into the new header __threading_support. The motivation is to make it easy to re-target libcxx into platforms that do not support pthread. Original patch from Fulvio Esposito (fulvio.esposito@outlook.com) - D11781 Applied with tweaks - D19412 Change-Id: I301111f0075de93dd8129416e06babc195aa936b llvm-svn: 268734

| | | | | | | | | | 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

| | | | | | condition_variable::wait, call terminate() rather than throwing an error. Do this indirectly, by marking the call as 'noexcept'. This is better than just calling terminate() directly, because it gives a better error message on the console. llvm-svn: 204778
* Change sleep_for, sleep_until, and the condition_variable timed waitHoward Hinnant2012-08-301-2/+14
| | | | | | | | | | | | | functions to protect against duration and time_point overflow. Since we're about to wait anyway, we can afford to spend a few more cycles on this checking. I purposefully did not treat the timed try_locks with overflow checking. This fixes http://llvm.org/bugs/show_bug.cgi?id=13721 . I'm unsure if the standard needs clarification in this area, or if this is simply QOI. The <chrono> facilities were never intended to overflow check, but just to not overflow if durations stayed within +/- 292 years. llvm-svn: 162925
