128-bit SVE

Set each predicate bit in (3) corresponding to a 32-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 32-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 32-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 32-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.

2048-bit SVE

Set each predicate bit in (3) corresponding to a 32-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.
