Subject: AVX-512. Split out mask version for vec_extract_hi_<mode>.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=01e3391a9085119eea88593f6b6a766294ee3631;p=gcc.git

AVX-512. Split out mask version for vec_extract_hi_<mode>.

gcc/
	* config/i386/sse.md (define_insn "vec_extract_hi_<mode>_maskm"):
	Remove "prefix_extra".
	(define_insn "vec_extract_hi_<mode>_mask"): New.
	(define_insn "vec_extract_hi_<mode>"): Remove masking.
gcc/testsuite/
	* gcc.target/i386/avx512vl-vextractf32x4-1.c: Fix scan pattern.
