2013-03-26[Preprocessor/Modules] Separate the macro directives kinds into their own ↵Argyrios Kyrtzidis
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
2013-03-26[ms-cxxabi] Mangle vector typesReid Kleckner
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.

2013-03-23Revert svn r176894 and r177658.Bob Wilson
Changing -ccc-install-dir to affect cc1's resource-dir setting broke our internal LNT tests. After discussing the situation with Jim, we've decided to pursue an alternate approach. We really want the resource-dir to be located relative to clang, even when using -ccc-install-dir, but we're going to add a fallback setting for the libc++ headers if they don't exist alongside the compiler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177815 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-23[analyzer] Teach constraint managers about unsigned comparisons.Jordan Rose
In C, comparisons between signed and unsigned numbers are always done in unsigned-space. Thus, we should know that "i >= 0U" is always true, even if 'i' is signed. Similarly, "u >= 0" is also always true, even though '0' is signed.
