128-bit SVE

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

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

For each 16-bit index from (2), if 0 ≤ (2) < 32, set (3) to the 16-bit element at that index in (1), otherwise set (3) to zero.

Larger sizes

For each 16-bit index from (2), if 0 ≤ (2) < 64, set (3) to the 16-bit element at that index in (1), otherwise set (3) to zero.

For each 16-bit index from (2), if 0 ≤ (2) < 128, set (3) to the 16-bit element at that index in (1), otherwise set (3) to zero.
