* Move all sources from the llvm project into contrib/llvm-project.Dimitry Andric2019-12-201-144/+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

* 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.
