VSUBPH zmm {k}, zmm, zmm
Synopsis
 _mm512_mask_sub_ph(__m512h src, __mmask32 k, __m512h a, __m512h 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 writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 TO 31
	IF k[j]
		dst.fp16[j] := a.fp16[j] - b.fp16[j]
	ELSE
		dst.fp16[j] := src.fp16[j]
	FI
ENDFOR
dst[MAX:512] := 0
