128-bit SVE

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

For each 64-bit index from (2), if 0 ≤ (2) < 4, set (3) to the 64-bit element at that index in (1), otherwise set (3) to zero.

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

Larger sizes

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

For each 64-bit index from (2), if 0 ≤ (2) < 32, set (3) to the 64-bit element at that index in (1), otherwise set (3) to zero.
