As you may know, GCC 4.X can use SSEx instead of FPU even for the scalar operations. Besides, it has some SSEx intrinsics which helps us to use them for both scalar and vector operations. Does D handle the SSE-like code generation ? does it allow us to use SSEx intrinsics ? does it include DirectX and OpenGL libraries ?

Regards.

I know for a fact that D lets you use SSE and SSE2 when you use the asm{} statement.  If worst comes to worst, you could definitely write the part that needs optimization in asm.

I'm not sure about SSE3 and x86_64.
