Subject: AVX-512. Extend ashrv insn patterns.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=28e9a294c7adb1a35e286d0e648d98b35d445277;p=gcc.git

AVX-512. Extend ashrv insn patterns.

gcc/
	* config/i386/sse.md (define_mode_iterator VI248_AVX512BW_AVX512VL):
	New.
	(define_mode_iterator VI24_AVX512BW_1): Ditto.
	(define_insn "<mask_codefor>ashr<mode>3<mask_name>"): Ditto.
	(define_insn "<mask_codefor>ashrv2di3<mask_name>"): Ditto.
	(define_insn "ashr<VI248_AVX512BW_AVX512VL:mode>3<mask_name>"): Enable
	also for TARGET_AVX512VL.
	(define_expand "ashrv2di3"): Update to enable TARGET_AVX512VL.
