The needles loads and stores would make it impossible to write an efficient 
simd add function even if the functions containing asm blocks could be inlined.

Yes, this is indeed a problem, and as far as I'm aware, usually solved 
in the gamedev world by using the (SSE) intrinsics your favorite C++ 
compiler provides, instead of resorting to inline asm.
