Synopsis
_mm512_mask_fmadd_round_ps(__m512 a, __mmask16 k, __m512 b, __m512 c, int rounding);
Description
Multiply packed single-precision (32-bit) floating-point elements in "a" and "b", add the intermediate result to packed elements in "c", and store the results in "dst" using writemask "k" (elements are copied from "a" when the corresponding mask bit is not set).

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