Nice to have in Phobos. I assume you have to set the correct control word depending on whether you perform math on the FPU or via SSE (as is standard for x86_64)? And I assume further that DMD always uses FPU math and other compilers provide flags to switch between FPU and SSE?
I don't know which compiler use which. On x86_64, a compiler is in practice free to mix-and-match FPU and SSE, the instructions are still there and working.
