* Try to fix thread name truncation on non-Windows.Zachary Turner2017-03-041-6/+13

* Improve the Threading code on NetBSDKamil Rytarowski2017-03-041-5/+2
| | | | | | | | Do not include <sys/user.h> on NetBSD. It's dead file and will be removed. No need to include <sys/sysctl.h> in this code context on NetBSD. llvm-svn: 296973

* Try again to appease the FreeBSD bot.Zachary Turner2017-03-031-7/+2
| | | | | | | The actual logic was wrong, not just the type conversion. This should get it correct. llvm-svn: 296899
* Try to appease the FreeBSD bots.Zachary Turner2017-03-031-2/+2
| | | | | | | | pthread_self() returns a pthread_t, but we were setting it to an int. It seems the cast to int when calling sysctl is still the correct thing to do, though. llvm-svn: 296892
* Add #include for unistd.h on Linux.Zachary Turner2017-03-031-0/+1

* [Support] Provide access to current thread name/thread id.Zachary Turner2017-03-031-0/+181
| | | | | | | | | | | | | | | | Applications often need the current thread id when making system calls, and some operating systems provide the notion of a thread name, which can be useful in enabling better diagnostics when debugging or logging. This patch adds an accessor for the thread id, and "best effort" getters and setters for the thread name. Since this is non critical functionality, no error is returned to indicate that a platform doesn't support thread names. Differential Revision: https://reviews.llvm.org/D30526 llvm-svn: 296887

| | | | | | | | | | | | | | | | | | | | | | ManagedStatic.cpp by using llvm_call_once to initialize the ManagedStatic mutex" This reverts commit r221331 and reinstate r220932 as discussed in D19271. Original commit message was: This patch adds an llvm_call_once which is a wrapper around std::call_once on platforms where it is available and devoid of bugs. The patch also migrates the ManagedStatic mutex to be allocated using llvm_call_once. These changes are philosophically equivalent to the changes added in r219638, which were reverted due to a hang on Win32 which was the result of a bug in the Windows implementation of std::call_once.

* Revert 220932.Jiangning Liu2014-11-051-5/+0
| | | | | | | | | Commit 220932 caused crash when building clang-tblgen on aarch64 debian target, so it's blocking all daily tests. The std::call_once implementation in pthread has bug for aarch64 debian. llvm-svn: 221331
