2017-12-01[ubsan] Re-commit: lit changes for lld testing, future lto testing.Roman Lebedev
Summary: As discussed in https://github.com/google/oss-fuzz/issues/933, it would be really awesome to be able to use ThinLTO for fuzzing. However, as @kcc has pointed out, it is currently undefined (untested) whether the sanitizers actually function properly with LLD and/or LTO. This patch is inspired by the cfi test, which already do test with LTO (and/or LLD), since LTO is required for CFI to function. I started with UBSan, because it's cmakelists / lit.* files appeared to be the cleanest. This patch adds the infrastructure to easily add LLD and/or LTO sub-variants of the existing lit test configurations. Also, this patch adds the LLD flavor, that explicitly does use LLD to link. The check-ubsan does pass on my machine. And to minimize the [initial] potential buildbot breakage i have put some restrictions on this flavour. Please review carefully, i have not worked with lit/sanitizer tests before. The original attempt, r319525 was reverted in r319526 due to the failures in compiler-rt standalone builds.

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.

2016-10-18[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.
