Synopsis
_mm256_mask_sub_ps(__m256 src, __mmask8 k, __m256 a, __m256 b);
Description
Subtract packed single-precision (32-bit) floating-point elements in "b" from packed single-precision (32-bit) floating-point elements in "a", and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
i := j*32
IF k[j]
dst[i+31:i] := a[i+31:i] - b[i+31:i]
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:256] := 0
