* Fix Libc++ build with MinGW64Eric Fiselier2017-05-311-1/+1
| | | | | | | | | | | | | | Summary: This patch corrects the build errors I encountered when building on MinGW64.

* Fix the build of thread.cpp on CloudABI.Ed Schouten2017-02-111-2/+2
| | | | | | | CloudABI does provide unistd.h, but doesn't define __unix__. We need to include this header file to make hardware_concurrency work. llvm-svn: 294832
* Threading support: externalize sleep_for() function.Asiri Rathnayake2017-02-091-26/+2
| | | | | | | | | | Different platforms implement the wait/sleep functions in difrerent ways. It makes sense to externalize this into the threading API. Differential revision: https://reviews.llvm.org/D29630 Reviewers: EricWF, joerg llvm-svn: 294573

* thread: implement sleep_for on WindowsSaleem Abdulrasool2017-01-071-0/+7
| | | | | | | | | | Windows does not provide an implementation of `nanosleep`. Round up the time duration to the nearest ms and use `Sleep`. Although this may over-sleep, there is no hard real-time guarantee on the wake, so sleeping a bit more is better than under-sleeping as it within the specification. llvm-svn: 291331
* clean up use of _WIN32Saleem Abdulrasool2017-01-031-5/+6
| | | | | | | | | Replace the use of _WIN32 in libc++. Replace most use with a C runtime check _LIBCPP_MSVCRT or the new _LIBCPP_WIN32 to indicate that we are using the Win32 API. Use a new _LIBCPP_WCHAR_IS_UCS2 to indicate that we are on an environment that has a short wchar_t. llvm-svn: 290910

* [libcxx] Fix thread join.pass.cpp segfault after r271475Asiri Rathnayake2016-06-031-4/+7
| | | | | | | | | | | | | | | Some pthread implementations do not like being called pthead_join() with the pthread_t argument set to 0, and causes a segfault. This patch fixes this issue by validating the pthread_t argument before invoking pthread_join(). NFC.

* Refactor pthread usage of libcxx.Asiri Rathnayake2016-05-061-2/+2
| | | | | | | | | | | | | 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.

* [libcxx] Whitelist inclusion of sysctl.h instead of blacklistingBen Craig2016-01-291-3/+8
| | | | | | | | | | | Instead of excluding all known operating systems that are not derived from BSD, I now include all operating systems that claim to be derived from BSD. Hopefully, that will make it so that this check doesn't need to change for every new operating system that comes along. http://reviews.llvm.org/D16634 llvm-svn: 259193
* Don't include <sys/sysctl.h> on CloudABI.Ed Schouten2015-03-101-2/+2
| | | | | | | As CloudABI does not provide sysctl(), this header is not present. Make thread.cpp build correctly (and pass all tests) by not including the header. llvm-svn: 231768
* libc++: support NaCl when building thread.cppJF Bastien2014-12-021-4/+4
| | | | | | | | | | | | | | Summary: NaCl shouldn't include sysctl.h when trying to determine std::thread::hardware_concurrency, it should instead use sysconf(_SC_NPROCESSORS_ONLN) through unistd.h. No test needs to be changed, since hardware_concurrency.pass.cpp already tests that std::thread::hardware_concurrency > 0.

* Matthew Dempsky: POSIX defines that the _POSIX_C_SOURCE macros are to be set ↵Howard Hinnant2013-06-301-3/+3
| | | | | | | | | | | | | | | | | | | | by user code to specify what version of POSIX the system should provide. If you want to check what version of POSIX is actually available, you're supposed to test _POSIX_VERSION. However, since sysconf() has been in POSIX since 1995, it's probably safe to assume it's available on any system with a C++11 compiler, especially if _SC_NPROCESSORS_ONLN is defined too. So no point in a complicated preprocessor rule if just we unconditionally include <unistd.h> (on non-Windows systems). Also, I've added a #warning for to help porters detect when a suitable implementation isn't detected at compile-time. Howard: Matthew, can you patch CREDITS.TXT? Thanks. llvm-svn: 185275

| | | | | | | | | | | | | 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
