* config/i386/i386.c (override_options): Enable
SSE prefetches with -mtune, as long as we are
compiling for i686 or higher. All i686 processors
accept SSE prefetches as NOPS, some i586's don't.
2004-07-08 Jakub Jelinek <jakub@redhat.com>
* gcc.mist-tests/i386-prefetch.exp (PREFETCH_SSE): Change all
-march=i386 into -march=i686. Add -march=i686 -mtune=x and
-march=x for pentium3, pentium3m, pentium-m, pentium4m,
prescott and c3-2.
(PREFETCH_3DNOW): Add -march=c3.
