* Move all sources from the llvm project into contrib/llvm-project.Dimitry Andric2019-12-2055-16462/+0
| | | | | | | | | | | | | This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940

| | | | | | | | | | | | | | | | | | | | | Rework recursive_timed_mutex so that it uses __thread_id instead of using the lower-level __libcpp_thread_id. This is prep for fixing PR42918. Reviewed as https://reviews.llvm.org/D65895 Pull in r368916 from upstream libc++ trunk (by Marshall Clow): Fix thread comparison by making sure we never pass our special 'not a thread' value to the underlying implementation. Fixes PR#42918. This should fix std::thread::id::operator==() attempting to call pthread_equal(3) with zero values.

* Temporarily revert upstream llvm trunk r240144 (by Michael Zolotukhin):Dimitry Andric2015-10-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | [SLP] Vectorize for all-constant entries. This should fix libc++'s iostream initialization SIGBUSing on amd64, whenever the global cout symbol is not aligned to 16 bytes. Some further explanation: libc++'s iostream.cpp contains the definitions of std::cout, std::cerr and so on. These global objects are effectively declared with an alignment of 8 bytes. When an executable is linked against libc++.so, it can sometimes get a copy of the global object, which is then at the same alignment. However, with clang 3.7.0, the initialization of these global objects will incorrectly use SSE instructions (e.g. movdqa), whenever the optimization level is high enough, and SSE is enabled, such as on amd64. When any of these objects is not aligned to 16 bytes, this will result in a SIGBUS during iostream initialization. In contrast, clang 3.6.x and earlier took the 8 byte alignment into consideration, and avoided SSE for those particular operations. After bisecting of upstream changes, I found that the above revision caused the change of this behavior, so I am reverting it now as a workaround, while a discussion and test case is being prepared for upstream.

Additionally, supply the missing stub __libcpp_relaxed_store(), as proposed in http://reviews.llvm.org/D13051 NOTE: this needs to be fixed properly later on, by supplying library functions implementing atomic operations for arm < v6. We should probably take those from sys/arm/arm/stdatomic.c, and stuff them into either libgcc or compiler-rt. Notes: svn path=/projects/clang370-import/; revision=288121
