2013-03-27UBSan: Don't diagnose inf/nan conversions between floating-point types. It's ↵Richard Smith
far from clear whether these have undefined behavior, and these checks are helping no-one. Keep the double->float overflow warnings, though, since those are useful in practice, even though it's unclear whether such operations have defined behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178194 91177308-0d34-0410-b5e6-96231b3b80d8

These types will not have a CXXConstructExpr to do the initialization for them.

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

this is a case where the system macro uses a not identical definition compared to a macro from the clang headers. For example (these come from different modules): \#define LONG_MAX __LONG_MAX__ (clang's limits.h) \#define LONG_MAX 0x7fffffffffffffffL (system's limits.h) in which case don't mark them ambiguous to avoid the "ambiguous macro expansion" warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178109 91177308-0d34-0410-b5e6-96231b3b80d8

Also update "test/Modules/macros.c" to test modified semantics: -When there is an ambiguous macro, expand using the latest introduced version, not the first one. -#undefs in submodules cause the macro to not be exported by that submodule, it doesn't cause undefining of macros in the translation unit that imported that submodule.
