Subject: i386: Emulate MMX mmx_umulv4hi3_highpart with SSE
X-Git-Tag: upstream/12.2.0~24651
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9377b54a62a4b6424194c3f9d755eb0f84fce726;p=platform%2Fupstream%2Fgcc.git

i386: Emulate MMX mmx_umulv4hi3_highpart with SSE

Emulate MMX mmx_umulv4hi3_highpart with SSE.  Only SSE register source
operand is allowed.

	PR target/89021
	* config/i386/mmx.md (mmx_umulv4hi3_highpart): Also check
	TARGET_MMX and TARGET_MMX_WITH_SSE.
	(*mmx_umulv4hi3_highpart): Add SSE emulation.
