LLVM supports the g++ C++ ABI. Your change breaks that. Please note that
this is not a Windows issue, it is a MSVC++ issue, as g++ works fine on
There are other issues with paramenter passing and the MSVC++ ABI, see
IIRC LLVM needs susbstantial modifications for supporting function calls
compatible with MSVC++, or the frontend that uses LLVM has to do quite a
bit of hacking for working around LLVM's limitations.
