Synopsis
_mm512_mask_addn_round_ps(__m512 src, __mmask16 k, __m512 v2, __m512 v3, int rounding);
Description
Performs element by element addition between packed single-precision (32-bit) floating-point elements in "v2" and "v3" and negates the sum, storing the result in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).

Operation

ELSE
dst[i+31:i] := src[i+31:i]
