128-bit SVE

For each even unsigned 32-bit integer set the double-width (2) to (1) << const. The shift amount is limited to 0 ≤ const ≤ 31.
256-bit SVE

For each even unsigned 32-bit integer set the double-width (2) to (1) << const. The shift amount is limited to 0 ≤ const ≤ 31.
512-bit SVE

For each even unsigned 32-bit integer set the double-width (2) to (1) << const. The shift amount is limited to 0 ≤ const ≤ 31.
