Instruction
VPEXPANDW xmm {k}, m128
Synopsis
 _mm_mask_expandloadu_epi16(__m128i src, __mmask8 k, const void* mem_addr);
Description
Load contiguous active 16-bit integers from unaligned memory at "mem_addr" (those with their respective bit set in mask "k"), and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
m := 0
FOR j := 0 to 7
	i := j*16
	IF k[j]
		dst[i+15:i] := MEM[mem_addr+m+15:mem_addr+m]
		m := m + 16
	ELSE
		dst[i+15:i] := src[i+15:i]
	FI
ENDFOR
dst[MAX:128] := 0
