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.

2016-06-17Fix most MSVC warnings in compiler-rt profiling libraryReid Kleckner
Here's the warnings and how they were fixed: - InstrProfilingUtil.c(110): warning C4013: '_open_osfhandle' undefined; assuming extern returning int Include io.h to get the prototype. - warning C4005: 'FILE_MAP_EXECUTE': macro redefinition Stop trying to support pre-XP versions of Windows, don't attempt to define this macro. - InstrProfilingWriter.c(271): warning C4221: nonstandard extension used: 'Data': cannot be initialized using address of automatic variable 'Header' - InstrProfilingWriter.c(275): warning C4221: nonstandard extension used: 'Data': cannot be initialized using address of automatic variable 'Zeroes' Turn this warning off. This is definitely legal in C++, all compilers accept it, and I only have room for half of one language standard in my brain. - InstrProfilingValue.c(320): warning C4113: 'uint32_t (__cdecl *)()' differs in parameter lists from 'uint32_t (__cdecl *)(void)' Fix this with an explicit (void) in the prototype. - InstrProfilingMerge.c.obj : warning LNK4006: _VPMergeHook already defined in InstrProfilingMergeFile.c.obj; second definition ignored Last remaining warning. This is from linking a selectany definition with a strong definition. We need to sort out weak symbols in compiler-rt in general, though. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@273026 91177308-0d34-0410-b5e6-96231b3b80d8

2016-03-28[libprofile] Handle '\\' in __llvm_profile_recursive_mkdirSean Silva
This is implicitly needed at least by gcc-flag-compatibility.test The thing that needs it is the `\` preceding the "default.profraw" appended internally by clang when doing `-fprofile-use=`. Clang uses `\` because is uses sys::path::append which will use `\` on a Windows host. This is wrong, but I don't think there's an easy way to solve it (maybe just always using `/` since places that accept `\` also tend to accept `/`, but not the other way around). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@264665 91177308-0d34-0410-b5e6-96231b3b80d8
