Subject: AVX-512. 74/n. Add byte/word max/mix reduction.
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9c9987c58ab90e785a65a48b73304a5a8cc17adc;p=thirdparty%2Fgcc.git

AVX-512. 74/n. Add byte/word max/mix reduction.

gcc/
	* config/i386/i386.c
	(emit_reduc_half): Handle V64QI and V32HI mode.
	* config/i386/sse.md
	(define_mode_iterator VI_AVX512BW): New.
	(define_expand "reduc_<code>_<mode>"): Use VI512_48F_12BW.
