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.

2017-09-15Resubmit "[lit] Force site configs to run before source-tree configs"Zachary Turner
This is a resubmission of r313270. It broke standalone builds of compiler-rt because we were not correctly generating the llvm-lit script in the standalone build directory. The fixes incorporated here attempt to find llvm/utils/llvm-lit from the source tree returned by llvm-config. If present, it will generate llvm-lit into the output directory. Regardless, the user can specify -DLLVM_EXTERNAL_LIT to point to a specific lit.py on their file system. This supports the use case of someone installing lit via a package manager. If it cannot find a source tree, and -DLLVM_EXTERNAL_LIT is either unspecified or invalid, then we print a warning that tests will not be able to run.

2017-09-14[lit] Force site configs to be run before source-tree configsZachary Turner
This patch simplifies LLVM's lit infrastructure by enforcing an ordering that a site config is always run before a source-tree config. A significant amount of the complexity from lit config files arises from the fact that inside of a source-tree config file, we don't yet know if the site config has been run. However it is *always* required to run a site config first, because it passes various variables down through CMake that the main config depends on. As a result, every config file has to do a bunch of magic to try to reverse-engineer the location of the site config file if they detect (heuristically) that the site config file has not yet been run. This patch solves the problem by emitting a mapping from source tree config file to binary tree site config file in llvm-lit.py. Then, during discovery when we find a config file, we check to see if we have a target mapping for it, and if so we use that instead. This mechanism is generic enough that it does not affect external users of lit. They will just not have a config mapping defined, and everything will work as normal. On the other hand, for us it allows us to make many simplifications: * We are guaranteed that a site config will be executed first * Inside of a main config, we no longer have to assume that attributes might not be present and use getattr everywhere. * We no longer have to pass parameters such as --param llvm_site_config=<path> on the command line. * It is future-proof, meaning you don't have to edit llvm-lit.in to add support for new projects. * All of the duplicated logic of trying various fallback mechanisms of finding a site config from the main config are now gone. One potentially noteworthy thing that was required to implement this change is that whereas the ninja check targets previously used the first method to spawn lit, they now use the second. In particular, you can no longer run lit.py against the source tree while specifying the various `foo_site_config=<path>` parameters. Instead, you need to run llvm-lit.py.

2017-06-29[profile] Move __llvm_profile_filename into a separate objectVedant Kumar
Users can specify the path a raw profile is written to by passing -fprofile-instr-generate=<path>, but this functionality broke on Darwin after __llvm_profile_filename was made weak [1], resulting in profiles being written to "default.profraw" even when <path> is specified. The situation is that instrumented programs provide a weak definition of __llvm_profile_filename, which conflicts with a weak redefinition provided by the profiling runtime. The linker appears to pick the 'winning' definition arbitrarily: on Darwin, it usually prefers the larger definition, which is probably why the instrprof-override-filename.c test has been passing. The fix is to move the runtime's definition into a separate object file within the archive. This means that the linker won't "see" the runtime's definition unless the user program has not provided one. I couldn't think of a great way to test this other than to mimic the Darwin failure: use -fprofile-instr-generate=<some-small-path>. Testing: check-{clang,profile}, modified instrprof-override-filename.c.

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.

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.
