[cfe-dev] DirectXMath with Clang-cl

Hello Clang-World,

I tried to compile a simple DirectXMath-Programm with the new clang-cl.
int main(int argc, char **argv)
{
        DirectX::XMVECTOR data{120.0f, 240.0f};

        data = DirectX::XMVectorMultiply(data, DirectX::XMVECTOR{2.0f, 
3.6f});

        printf("Result: {%f, %f}\n", DirectX::XMVectorGetX(data), 
DirectX::XMVectorGetY(data));
        system("PAUSE");

        return 0;
}

But the compiler fails with >20 Errors, like:
"1>  In file included from main.cpp:1:
1>  In file included from C:\Program Files (x86)\Windows 
Kits\8.1\Include\um\DirectXMath.h:1884:
1>C:\Program Files (x86)\Windows 
Kits\8.1\Include\um/DirectXMathVector.inl(412,13): error : member 
reference base type 'DirectX::FXMVECTOR' (aka 'const __m128') is not a 
structure or union
1>      return V.m128_f32[i];"

I know, that windows defines __m128 in a different way than clang, but is 
there no way to use DirectXMath or DirectX with Clang? Will there one day 
a way to do so?

Kind regards
