FWIW, using these flags, the linker complains:
-ftree-vectorize -ftree-vectorizer-verbose=3 -fast -fPIC -
mcpu=7450 -mtune=7450
neither -fast nor the 7450 cpu are supported in the GCC I have, an
Ubuntu i386 that comes with GCC 4.0.3. With the rest of the
options, it doesn't complain.
But then, if you're on OSX... OSX doesn't use ELF. It can very well
be not the same as Linux in that situation.
-fast is a shortcut for:
-O3 -falign-loops-max-skip=15 -falign-jumps-max-skip=15
-falign-loops=16 -falign-jumps=16 -falign-functions=16 -

-mtune=G5 (unless -mtune=G4 is specified). -fsched-
