Subject: i386: Emulate MMX mmx_pmaddwd with SSE
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d0e9bf2a6db4df95b776c5bcd728f0e159116659;p=gcc.git

i386: Emulate MMX mmx_pmaddwd with SSE

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

	PR target/89021
	* config/i386/mmx.md (mmx_pmaddwd): Also allow TARGET_MMX_WITH_SSE.
	(*mmx_pmaddwd): Also allow TARGET_MMX_WITH_SSE.  Add SSE support.
