Regarding PathScale Compilers, I have this from one of our compiler engineers:
If the code already uses SSE2 intrinsics, the PathScale compiler does not need
any "magic switches" for SSE2 intrinsics to be enabled. Some applications may
need a configuration switch like --enable-sse for the application to use sse
intrinsics. This is just a configure switch for the application, and not an
option for the compiler.
