	* Backport from mainline:
	2004-07-08  Paolo Bonzini  <bonzini@gnu.org>
	Jakub Jelinek  <jakub@redhat.com>
	
	* 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.
	
	2004-07-07  Jakub Jelinek  <jakub@redhat.com>
	
	* config/i386/i386.c (override_options): Don't set x86_prefetch_sse
	from -mtune= option.
	
	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 -mcpu=prescott and
	-march=prescott.
	(PREFETCH_3DNOW): Add -march=c3.
	
	2003-08-04  Janis Johnson  <janis187@us.ibm.com>
	
	PR target/11739
	* gcc.misc-tests/i386-prefetch.exp: Use -march=i386 when specifying
	a value for -mcpu.
