I'm not sure the Xcode assembler support s the .weak directive. I think if clang is targeting darwin it will not generate this directive, but since we are targeting -ccc-host-triple x86_64-pc-win32-macho it may be getting generated.
Not sure if it is possible to turn o __weak_alias when you build with Xcode?
