Subject: sse.md (*<ssse3_avx2>_pmulhrsw<mode>3<mask_name>): Use constraint x instead of v... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7b37ce10ceccdbf3d330743b90f1aa58f826feb0;p=gcc.git

sse.md (*<ssse3_avx2>_pmulhrsw<mode>3<mask_name>): Use constraint x instead of v in second alternative, add avx512bw alternative.

	* config/i386/sse.md (*<ssse3_avx2>_pmulhrsw<mode>3<mask_name>): Use
	constraint x instead of v in second alternative, add avx512bw
	alternative.

	* gcc.target/i386/avx512vl-vpmulhrsw-3.c: New test.
	* gcc.target/i386/avx512bw-vpmulhrsw-3.c: New test.
