2017-02-16[PGO] Suspend SIGKILL for PR_SET_PDEATHSIG in profile-writeRong Xu
Summary: We found a nondeterministic behavior when doing online profile merging for multi-process applications. The application forks a sub-process and sub-process sets to get SIGKILL when the parent process exits, The first process gets the lock, and dumps the profile. The second one will mmap the file, do the merge and write out the file. Note that before the merged write, we truncate the profile. Depending on the timing, the child process might be terminated abnormally when the parent exits first. If this happens: (1) before the truncation, we will get the profile for the main process (2) after the truncation, and before write-out the profile, we will get 0 size profile. (3) after the merged write, we get merged profile. This patch temporarily suspend the SIGKILL for PR_SET_PDEATHSIG before profile-write and restore it after the write. This patch only applies to Linux system.

2016-11-29[profile] use GetComputerNameExW instead of gethostname on WindowsBob Haarman
Summary: In profile data paths, we replace "%h" with the hostname of the machine the program is running on. On Windows, we used gethostname() to obtain the hostname. This requires linking with ws2_32. With this change, we instead get the hostname from GetComputerNameExW(), which does not require ws2_32.

2016-10-18[profile] Mark lprofCurFilename as COMPILER_RT_WEAKVedant Kumar
This makes __llvm_profile_set_filename() work across dylib boundaries on Darwin. This functionality was originally meant to work on all platforms, but was moved to a Linux-only directory with r272404. The root cause of the test failure on Darwin was that lprofCurFilename was not marked weak. Each dylib maintained its own copy of the variable due to the two-level namespace. Tested with check-profile (on Darwin). I don't expect this to regress other platforms.

2016-09-23Revert "[profile] Hide lprofCurFilename"Vedant Kumar
This reverts commit r282294. It breaks a Linux bot: http://lab.llvm.org:8011/builders/clang-cmake-aarch64-42vma/builds/12180 It looks like the test checks that __llvm_profile_set_filename() alters the raw profile filename in both the dylib and the main program. Now that lprofCurFilename is hidden, this can't work, and we get two profiles (one for the call to "main" and one for "func"). Back this change out so that we don't affect external users. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@282304 91177308-0d34-0410-b5e6-96231b3b80d8
