The only thing -g should do is enable debugging symbols; it doesn't
generally have an effect on optimization.  Perhaps you mean -O0?
I believe there's also a -mno-altivec switch, but I think that
might only disable use of AltiVec intrinsics (i.e. I have no idea
if it affects automatic vectorization).
