2013-03-27Revert "[lib/Headers] Define NULL as __DARWIN_NULL when on __APPLE__."Argyrios Kyrtzidis
Per feedback by Doug, we should avoid platform-specific implementations in lib/Headers as much as possible. This reverts commit r178110. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178181 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-27[lib/Headers] Break the module import cycle between _Builtin_intrinsics.sse ↵Argyrios Kyrtzidis
and _Builtin_intrinsics.sse2 Module "sse" implicitly exports module "sse2". This is bad because we also have module "sse2" export module "sse" (as intended) so we end up with a cycle in the module import graph: 1. sse2 -> (also imports) sse 2. sse -> (also imports) sse2 To eliminate the cycle remove 2.; importing module "sse2" will also import module "sse", but just importing module "sse" will not also import module "sse2". rdar://13240552 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178117 91177308-0d34-0410-b5e6-96231b3b80d8

MacroDirective's subclasses. For each macro directive (define, undefine, visibility) have a separate object that gets chained to the macro directive history. This has several benefits: -No need to mutate a MacroDirective when there is a undefine/visibility directive. Stuff like PPMutationListener become unnecessary. -No need to keep extra source locations for the undef/visibility locations for the define directive object (which is the majority of the directives) -Much easier to hide/unhide a section in the macro directive history. -Easier to track the effects of the directives across different submodules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178037 91177308-0d34-0410-b5e6-96231b3b80d8

Summary: The only vector types a user can pass from MSVC code to clang code are the ones from *mmintrin.h, so we only have to match the MSVC mangling for these types. MSVC mangles the __m128 family of types as tag types, which we match. For other vector types, we emit a unique tag type mangling that won't match anything produced by MSVC.
