Instruction
VSUBPH xmm {z}, xmm, xmm
Synopsis
 _mm_maskz_sub_ph(__mmask8 k, __m128h a, __m128h b);
Description
Subtract packed half-precision (16-bit) floating-point elements in "b" from packed half-precision (16-bit) floating-point elements in "a", and store the results in "dst" using zeromask "k" (elements are zeroed out 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]
	ELSE
		dst.fp16[j] := 0
	FI
ENDFOR
dst[MAX:128] := 0
