VCOMPRESSPD m512 {k}, zmm
Synopsis
 _mm512_mask_compressstoreu_pd(void* base_addr, __mmask8 k, __m512d a);
Description
Contiguously store the active double-precision (64-bit) floating-point elements in "a" (those with their respective bit set in writemask "k") to unaligned memory at "base_addr".
Operation
size := 64
m := base_addr
FOR j := 0 to 7
	i := j*64
	IF k[j]
		MEM[m+size-1:m] := a[i+63:i]
		m := m + size
	FI
