There are some benchmarks which require fewer switches to be used (such
as spec 2000) for measuring and reporting submissions.
Also in addition to that there have been some requests to have a switch
for k8 + sse3 because k8 has been supporting SSE3 for the past two years
and we don't have a switch which has both k8 and sse3 support.
One such request is at http://gcc.gnu.org/ml/gcc/2007-02/msg00403.html.
Thanks,
- Dwarak
