# DP: 
# DP: 	* config/i386/i386.c (override_options): Enable
# DP: 	SSE prefetches with -mtune, as long as we are
# DP: 	compiling for i686 or higher.  All i686 processors
# DP: 	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.
