Is there any way to use SSE/SSE2 intrinsics in C submissions? Currently, it seems the -msse/-msse2 flags are not passed to the compiler, making it impossible to use Intel's SIMD instructions in the programs.
You might want to post this in the Wishlist of the Online Judge Section of the forum. I suspect the answer will be no, because the judge doesn't work at that level. You can't be getting at the machine level, the security implications are wild.
