--- Comment #11 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
Conclusion is that we still need a fix to emmintrin.h along the lines of
Steve's original two comments.  Additionally, we need to fix trunk to complain
about the out of range value, rather than quietly substituting correct code gen
that was not requested.
