VMAXPS ymm {z}, ymm, ymm
Synopsis
_mm256_maskz_max_ps(__mmask8 k, __m256 a, __m256 b);
Description
Compare packed single-precision (32-bit) floating-point elements in "a" and "b", and store packed maximum values in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set). [max_float_note]
Operation
FOR j := 0 to 7
i := j*32
IF k[j]
dst[i+31:i] := MAX(a[i+31:i], b[i+31:i])
ELSE
dst[i+31:i] := 0
FI
ENDFOR
dst[MAX:256] := 0
