* Merging r312748:Tom Stellard2017-11-151-1/+5

This causes the builtin atomic functions (e.g.: __atomic_fetch_add) to not generate thread-safe assembly for these operations, which breaks our firmware. We target bare metal, and need to atomically modify variables in our interrupt routines, and task threads. Internally, the -mthread-model flag determines whether to lower or expand atomic operations (see D4984). This change removes the overridden thread model methods, and instead relies on the base ToolChain class to validate the thread model (which already includes logic to validate single thread model support). If the single thread model is required, the -mthread-model flag will have to be provided. As a workaround "-mthread-model posix" could be provided, but it only works due to a bug in the validation of the -mthread-model flag (separate patch coming to fix this). https://reviews.llvm.org/D37493 Patch by: Ian Tessier! ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/cfe/branches/release_50@314464 91177308-0d34-0410-b5e6-96231b3b80d8

This is provided on a best-effort basis; right now, this can be used to undo the ABI change in r310401, reverting Clang to its prior C++ ABI for pass/return by value of class types affected by that change, and to undo the ABI change in r262688, reverting Clang to using integer registers rather than SSE registers for passing <1 x long long> vectors. The intent is that we will maintain this backwards compatibility path as we make ABI-breaking fixes in future. The reversion to the old behavior for r310401 is also applied to the PS4 target since that change is not part of its platform ABI (which is essentially to do whatever Clang 3.2 did). ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/cfe/branches/release_50@312013 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ------------------------------------------------------------------------ r311391 | stl_msft | 2017-08-21 15:19:33 -0700 (Mon, 21 Aug 2017) | 28 lines [Driver] Recognize DevDiv internal builds of MSVC, with a different directory structure. This is a reasonably non-intrusive change, which I've verified works for both x86 and x64 DevDiv-internal builds. The idea is to change `bool IsVS2017OrNewer` into a 3-state `ToolsetLayout VSLayout`. Either a build is DevDiv-internal, released VS 2017 or newer, or released VS 2015 or older. When looking at the directory structure, if instead of `"VC"` we see `"x86ret"`, `"x86chk"`, `"amd64ret"`, or `"amd64chk"`, we recognize this as a DevDiv-internal build. After we get past the directory structure validation, we use this knowledge to regenerate paths appropriately. `llvmArchToDevDivInternalArch()` knows how we use `"i386"` subdirectories, and `MSVCToolChain::getSubDirectoryPath()` uses that. It also knows that DevDiv-internal builds have an `"inc"` subdirectory instead of `"include"`. This may still not be the "right" fix in any sense, but I believe that it's non-intrusive in the sense that if the special directory names aren't found, no codepaths are affected. (`ToolsetLayout::OlderVS` and `ToolsetLayout::VS2017OrNewer` correspond to `IsVS2017OrNewer` being `false` or `true`, respectively.) I searched for all references to `IsVS2017OrNewer`, which are places where Clang cares about VS's directory structure, and the only one that isn't being patched is some logic to deal with cross-compilation. I'm fine with that not working for DevDiv-internal builds for the moment (we typically test the native compilers), so I added a comment. Fixes D36860. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/cfe/branches/release_50@311500 91177308-0d34-0410-b5e6-96231b3b80d8

This is required when supporting multiple tool chains that target a single device type. In our particular use case, the OpenMP and CUDA tool chains will use the same ```addClangTargetOptions ``` method. This enables the reuse of common options and ensures control over options only supported by a particular tool chain.

This prevents diagnostics that do not meet a minimum hotness threshold from being output.
