128-bit SVE

For each even signed 16-bit integer set the double-width (2) to (1) << const. The shift amount is limited to 0 ≤ const ≤ 15.

256-bit SVE

For each even signed 16-bit integer set the double-width (2) to (1) << const. The shift amount is limited to 0 ≤ const ≤ 15.

512-bit SVE

For each even signed 16-bit integer set the double-width (2) to (1) << const. The shift amount is limited to 0 ≤ const ≤ 15.
