This does what you're asking for:

void test(ref float a, ref float b)
{
     asm
     {
         naked;
         movaps  XMM0,[RSI];
         addps   XMM0,[RDI];
         movaps  [RSI],XMM0;
         movaps  XMM0,[RSI];
         addps   XMM0,[RDI];
         movaps  [RSI],XMM0;
         ret;
     }
}
