Instruction
VDIVSH xmm {z}, xmm, xmm
Synopsis
 _mm_maskz_div_sh(__mmask8 k, __m128h a, __m128h b);
Description
Divide the lower half-precision (16-bit) floating-point element in "a" by the lower half-precision (16-bit) floating-point element in "b", store the result in the lower element of "dst" using zeromask "k" (the element is zeroed out when mask bit 0 is not set), and copy the upper 7 packed elements from "a" to the upper elements of "dst".
Operation
IF k[0]
	dst.fp16[0] := a.fp16[0] / b.fp16[0]
ELSE
	dst.fp16[0] := 0
FI
dst[127:16] := a[127:16]
dst[MAX:128] := 0
