128-bit SVE
Considering (3) and (4) as a double-length predicate, with the upper bits in (4), set each predicate bit corresponding to a 8-bit elements, from low to high, while (1) + n < (2), with n starting from zero and incrementing each bit. If a comparison fails, all higher predicate bits will also be set to zero.
(1), (2), and offsets computed from (1) are signed 64-bit integers.
256-bit SVE
Considering (3) and (4) as a double-length predicate, with the upper bits in (4), set each predicate bit corresponding to a 8-bit elements, from low to high, while (1) + n < (2), with n starting from zero and incrementing each bit. If a comparison fails, all higher predicate bits will also be set to zero.
(1), (2), and offsets computed from (1) are signed 64-bit integers.
512-bit SVE
Considering (3) and (4) as a double-length predicate, with the upper bits in (4), set each predicate bit corresponding to a 8-bit elements, from low to high, while (1) + n < (2), with n starting from zero and incrementing each bit. If a comparison fails, all higher predicate bits will also be set to zero.
