Subject: AVX-512. 62/n. Add vpmaddubsw,vdbpsadbw insn patterns.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5f64b49668022924dcb057e3f262facac7a93a69;p=gcc.git

AVX-512. 62/n. Add vpmaddubsw,vdbpsadbw insn patterns.

gcc/
	* config/i386/sse.md
	(define_c_enum "unspec"): Add UNSPEC_DBPSADBW, UNSPEC_PMADDUBSW512.
	(define_insn "avx512bw_pmaddubsw512<mode><mask_name>"): New.
	(define_insn "<mask_codefor>avx512bw_dbpsadbw<mode><mask_name>"):
	Ditto.
