VFMADD132PH xmm {k}, xmm, xmm
Synopsis
 _mm_mask3_fmadd_ph(__m128h a, __m128h b, __m128h c, __mmask8 k);
Description
Multiply packed half-precision (16-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 "c" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
	IF k[j]
		dst.fp16[j] := (a.fp16[j] * b.fp16[j]) + c.fp16[j]
	ELSE
		dst.fp16[j] := c.fp16[j]
	FI
ENDFOR
dst[MAX:128] := 0
