Synopsis
_mm512_mask_maxabs_ps(__m512 src, __mmask16 k, __m512 a, __m512 b);
Description
Determines the maximum of the absolute elements of each pair of corresponding elements of packed single-precision (32-bit) floating-point elements in "a" and "b", storing 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 15
i := j*32
IF k[j]
dst[i+31:i] := FpMax(ABS(a[i+31:i]), ABS(b[i+31:i]))
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
