2013-03-22[ms-cxxabi] Implement member data pointers for non-dynamic classesReid Kleckner
Summary: For non-dynamic classes (no virtual bases), member data pointers are simple offsets from the base of the record. Dynamic classes use an aggregate for member data pointers and are therefore currently unsupported. Unlike Itanium, the ms ABI uses 0 to represent null for polymorphic classes. Non-polymorphic classes use -1 like Itanium, since 0 is a valid field offset.

interaction to eliminate a pile of extraneous stats(). The refactoring in r177367 introduced a serious performance bug where the "lazy" resolution of module file names in the global module index to actual module file entries in the module manager would perform repeated negative stats(). The new interaction requires the module manager to inform the global module index when a module file has been loaded, eliminating the extraneous stat()s and a bunch of bookkeeping on both sides. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177750 91177308-0d34-0410-b5e6-96231b3b80d8

headers defining size_t/ptrdiff_t/wchar_t. Clang's <stddef.h> provides definitions for the C standard library types size_t, ptrdiff_t, and wchar_t. However, the system's C standard library headers tend to provide the same typedefs, and the two generally avoid each other using the macros _SIZE_T/_PTRDIFF_T/_WCHAR_T. With modules, however, we need to see *all* of the places where these types are defined, so provide the typedefs (ignoring the macros) when modules are enabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177686 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Split ubsan runtime into three pieces (clang part):Richard Smith
* libclang_rt-san-* is sanitizer_common, and is linked in only if no other sanitizer runtime is present. * libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on a C++ ABI library, and is always linked in. * libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a C++ ABI library, and is only linked in when linking a C++ binary. This change also switches us to using -whole-archive for the ubsan runtime (which is made possible by the above split), and switches us to only linking the sanitizer runtime into the main binary and not into DSOs (which is made possible by using -whole-archive). The motivation for this is to only link a single copy of sanitizer_common into any binary. This is becoming important now because we want to share more state between multiple sanitizers in the same process (for instance, we want a single shared output mutex). The Darwin ubsan runtime is unchanged; because we use a DSO there, we don't need this complexity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177605 91177308-0d34-0410-b5e6-96231b3b80d8
