Instruction
VCOMPRESSPS xmm {k}, xmm
Synopsis
_mm_mask_compress_ps(__m128 src, __mmask8 k, __m128 a);
Description
Contiguously store the active single-precision (32-bit) floating-point elements in "a" (those with their respective bit set in writemask "k") to "dst", and pass through the remaining elements from "src".
Operation
size := 32
m := 0
FOR j := 0 to 3
i := j*32
IF k[j]
dst[m+size-1:m] := a[i+31:i]
m := m + size
FI
ENDFOR
dst[127:m] := src[127:m]
dst[MAX:128] := 0
