Synopsis
_mm512_mask_log2_ps(__m512 src, __mmask16 k, __m512 a);
Description
Compute the base-2 logarithm of 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 15
i := j*32
IF k[j]
dst[i+31:i] := LOG(a[i+31:i]) / LOG(2.0)
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
