128-bit SVE

Zero extend each 32-bit element from the low half of (1) to 64 bits, writing the results to the 64-bit elements of (2) in the same order.

256-bit SVE

Zero extend each 32-bit element from the low half of (1) to 64 bits, writing the results to the 64-bit elements of (2) in the same order.

512-bit SVE

Zero extend each 32-bit element from the low half of (1) to 64 bits, writing the results to the 64-bit elements of (2) in the same order.
