128-bit SVE
Set (3) to the last (leftmost) 32-bit element from (2) where the corresponding predicate bit in (1) is non-zero. If there are no such elements, set (3) to the last (leftmost) element from (1).
256-bit SVE
Set (3) to the last (leftmost) 32-bit element from (2) where the corresponding predicate bit in (1) is non-zero. If there are no such elements, set (3) to the last (leftmost) element from (1).
512-bit SVE
Set (3) to the last (leftmost) 32-bit element from (2) where the corresponding predicate bit in (1) is non-zero. If there are no such elements, set (3) to the last (leftmost) element from (1).

1024-bit SVE
Set (3) to the last (leftmost) 32-bit element from (2) where the corresponding predicate bit in (1) is non-zero. If there are no such elements, set (3) to the last (leftmost) element from (1).
2048-bit SVE
Set (3) to the last (leftmost) 32-bit element from (2) where the corresponding predicate bit in (1) is non-zero. If there are no such elements, set (3) to the last (leftmost) element from (1).
