Hello!

2010-06-15  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.c (*prefetch_sse_<mode>):  Macroize insn from
	*prefetch_sse and *prefetch_sse_rex using P mode iterator.
	(*prefetch_3dnow_<mode>): Ditto from *prefetch_3dnow and
	*prefetch_3dnow_rex.

Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline.

Uros.
