128-bit SVE
Set each predicate bit in (3) corresponding to a 16-bit elements, from high to low, while (1) − n > (2), with n starting from zero and incrementing each bit. If a comparison fails, all lower predicate bits will also be set to zero.
(1), (2), and offsets computed from (1) are unsigned 64-bit integers.
256-bit SVE
Set each predicate bit in (3) corresponding to a 16-bit elements, from high to low, while (1) − n > (2), with n starting from zero and incrementing each bit. If a comparison fails, all lower predicate bits will also be set to zero.
(1), (2), and offsets computed from (1) are unsigned 64-bit integers.
512-bit SVE
Set each predicate bit in (3) corresponding to a 16-bit elements, from high to low, while (1) − n > (2), with n starting from zero and incrementing each bit. If a comparison fails, all lower predicate bits will also be set to zero.
(1), (2), and offsets computed from (1) are unsigned 64-bit integers.

1024-bit SVE
Set each predicate bit in (3) corresponding to a 16-bit elements, from high to low, while (1) − n > (2), with n starting from zero and incrementing each bit. If a comparison fails, all lower predicate bits will also be set to zero.

2048-bit SVE
Set each predicate bit in (3) corresponding to a 16-bit elements, from high to low, while (1) − n > (2), with n starting from zero and incrementing each bit. If a comparison fails, all lower predicate bits will also be set to zero.
