X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=66248623022d259e2f9f15c1a26e78c591286b1c;p=gcc.git

i386: Emulate MMX umulv1siv1di3 with SSE2

Emulate MMX umulv1siv1di3 with SSE2.  Only SSE register source operand
is allowed.

	PR target/89021
	* config/i386/mmx.md (sse2_umulv1siv1di3): Add SSE emulation
	support.
	(*sse2_umulv1siv1di3): Add SSE2 emulation.
