128-bit SVE
For each 16-bit integer set the even 8-bit elements of (2) to (1) >> const, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 8.
256-bit SVE
For each 16-bit integer set the even 8-bit elements of (2) to (1) >> const, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 8.
512-bit SVE
For each 16-bit integer set the even 8-bit elements of (2) to (1) >> const, and zero odd elements. The shift amount is limited to 1 ≤ const ≤ 8.
