Synopsis
 _mm_mask_fmadd_ps(__m128 a, __mmask8 k, __m128 b, __m128 c);
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).
Operation
FOR j := 0 to 3
	i := j*32
	IF k[j]
		dst[i+31:i] := (a[i+31:i] * b[i+31:i]) + c[i+31:i]
	ELSE
		dst[i+31:i] := a[i+31:i]
	FI
ENDFOR
dst[MAX:128] := 0
