Instruction
VCOMPRESSPD m128 {k}, xmm
Synopsis
_mm_mask_compressstoreu_pd(void* base_addr, __mmask8 k, __m128d 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 1
i := j*64
IF k[j]
MEM[m+size-1:m] := a[i+63:i]
m := m + size
