2019-01-15NFC: Replace iterator loop with cxx_range_forStephen Kelly
2019-01-15[clang-cl] Alias /Zc:alignedNew[-] to -f[no-]aligned-allocationReid Kleckner
Implements PR40180. clang-cl has one minor behavior difference with cl with this change. Clang allows the user to enable the C++17 feature of aligned allocation without enabling all of C++17, but MSVC will not call the aligned allocation overloads unless -std:c++17 is passed. While our behavior is technically incompatible, it would require making driver mode specific changes to match MSVC precisely, and clang's behavior is useful because it allows people to experiment with new C++17 features individually. Therefore, I plan to leave it as is.

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.

2019-01-15Fix cpu-dispatch MV regression caused by r347812Erich Keane
r347812 permitted forward declarations for cpu-dispatch functions, which are occassionally useful as exposition in header files. However, this inadvertently permitted this function to become multiversioned after a usage. This patch ensures that the "CausesMV" checks are still run in the forward-declaration case.

2019-01-15Reduce ASTMatchers stack footprint. Addresses http://llvm.org/PR38851Alexander Kornienko
The BoundNodesTreeBuilder class is used both directly and indirectly as a local variable in matchesAncestorOfRecursively, memoizedMatchesAncestorOfRecursively and other functions that happen to be on long recursive call paths. By reducing the inline storage size of the SmallVector we dramatically reduce the stack requirements of ASTMatchers. Running clang-tidy with a large number of checks enabled on a few arbitrarily chosen files show no performance regression.

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.

2019-01-14[AST] Fix double-traversal of code in top-level lambdas in RAV(implicit = yes).Sam McCall
Summary: Prior to r351069, lambda classes were traversed or not depending on the {Function, Class, Namespace, TU} DeclContext containing them. If it was a function (common case) they were not traversed. If it was a namespace or TU (top-level lambda) they were traversed as part of that DeclContext traversal. r351069 "fixed" RAV to traverse these as part of the LambdaExpr, which is the right place. But top-level lambdas are now traversed twice. We fix that as blocks and block captures were apparently fixed in the past. Maybe it would be nicer to avoid adding the lambda classes to the DeclContext in the first place, but I can't work out the implications of that.

2019-01-14[OpenCL] Set generic addr space of 'this' in special class members.Anastasia Stulova
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.
