128-bit SVE

For each 8-bit index from (2), if 0 ≤ (2) < 16, set (3) to the 8-bit element at that index in (1), otherwise set (3) to zero.

For each 8-bit index from (2), if 0 ≤ (2) < 32, set (3) to the 8-bit element at that index in (1), otherwise set (3) to zero.

For each 8-bit index from (2), if 0 ≤ (2) < 64, set (3) to the 8-bit element at that index in (1), otherwise set (3) to zero.

Larger sizes

For each 8-bit index from (2), if 0 ≤ (2) < 128, set (3) to the 8-bit element at that index in (1), otherwise set (3) to zero.

For each 8-bit index from (2), set (3) to the 8-bit element at that index in (1). Optional zeroing is not possible on 2048-bit SVE.
