2019-01-16[NewPM][TSan] Reiterate the TSan portPhilip Pfaffe
Summary: Second iteration of D56433 which got reverted in rL350719. The problem in the previous version was that we dropped the thunk calling the tsan init function. The new version keeps the thunk which should appease dyld, but is not actually OK wrt. the current semantics of function passes. Hence, add a helper to insert the functions only on the first time. The helper allows hooking into the insertion to be able to append them to the global ctors list.

2019-01-16[SemaCXX] Unconfuse Clang when std::align_val_t is unscoped in C++03Eric Fiselier
When -faligned-allocation is specified in C++03 libc++ defines std::align_val_t as an unscoped enumeration type (because Clang didn't provide scoped enumerations as an extension until 8.0). Unfortunately Clang confuses the `align_val_t` overloads of delete with the sized deallocation overloads which aren't enabled. This caused Clang to call the aligned deallocation function as if it were the sized deallocation overload. For example: https://godbolt.org/z/xXJELh This patch fixes the confusion. llvm-svn: 351294

2019-01-15[Tooling] Make clang-tool find libc++ dir on mac when running on a file ↵Haojian Wu
without compilation database. Summary: This is a regression of r348365. When clang-tools run on a file without a complation database (`clang-check /tmp/t.cc`), we will use fixed compilation database as a fallback. However the actual compiler path in the fallback complation command is just `clang-tool` which is insufficient to detect the libc++ dir.

2019-01-15[X86] Make _xgetbv/_xsetbv on non-windows platformsCraig Topper
Summary: This patch attempts to redo what was tried in r278783, but was reverted. These intrinsics should be available on non-windows platforms with "xsave" feature check. But on Windows platforms they shouldn't have feature check since that's how MSVC behaves. To accomplish this I've added a MS builtin with no feature check. And a normal gcc builtin with a feature check. When _MSC_VER is not defined _xgetbv/_xsetbv will be macros pointing to the gcc builtin name. I've moved the forward declarations from intrin.h to immintrin.h to match the MSDN documentation and used that as the header file for the MS builtin. I'm not super happy with this implementation, and I'm open to suggestions for better ways to do it.

Set address spaces of 'this' param correctly for implicit special class members. This also changes initialization conversion sequence to separate address space conversion from other qualifiers in case of binding reference to a temporary. In this case address space conversion should happen after the binding (unlike for other quals). This is needed to materialize it correctly in the alloca address space.

2019-01-14[AST] RecursiveASTVisitor visits lambda classes when implicit visitation is on.Sam McCall
Summary: This fixes ASTContext's parent map for nodes in such classes (e.g. operator()). https://bugs.llvm.org/show_bug.cgi?id=39949 This also changes the observed shape of the AST for implicit RAVs. - this includes AST MatchFinder: cxxRecordDecl() now matches lambda classes, functionDecl() matches the call operator, and the parent chain is body -> call operator -> lambda class -> lambdaexpr rather than body -> lambdaexpr. - this appears not to matter for the ASTImporterLookupTable builder - this doesn't matter for the other RAVs in-tree. In order to do this, we remove the TraverseLambdaBody hook. The problem is it's hard/weird to ensure this hook is called when traversing via the implicit class. There were just two users of this hook in-tree, who use it to skip bodies. I replaced these with explicitly traversing the captures only. Another approach would be recording the bodies when the lambda is visited, and then recognizing them later. I'd be open to suggestion on how to preserve this hook, instead.
