128-bit SVE

Set each predicate bit in (3) 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 unsigned 64-bit integers.

256-bit SVE

Set each predicate bit in (3) 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 unsigned 64-bit integers.

512-bit SVE

Set each predicate bit in (3) 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 unsigned 64-bit integers.

1024-bit SVE

Set each predicate bit in (3) 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 unsigned 64-bit integers.

2048-bit SVE

Set each predicate bit in (3) 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 unsigned 64-bit integers.
