VPEXPANDQ zmm {z}, m64
Synopsis
 _mm512_maskz_expandloadu_epi64(__mmask8 k, void const* mem_addr);
Description
Load contiguous active 64-bit integers from unaligned memory at "mem_addr" (those with their respective bit set in mask "k"), and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
m := 0
FOR j := 0 to 7
	i := j*64
	IF k[j]
		dst[i+63:i] := MEM[mem_addr+m+63:mem_addr+m]
		m := m + 64
	ELSE
		dst[i+63:i] := 0
	FI
ENDFOR
dst[MAX:512] := 0
