Synopsis
_mm512_maskz_compress_epi32(__mmask16 k, __m512i a);
Description
Contiguously store the active 32-bit integers in "a" (those with their respective bit set in zeromask "k") to "dst", and set the remaining elements to zero.
Operation

m := m + size
FI
ENDFOR
dst[511:m] := 0
dst[MAX:512] := 0
