128-bit SVE

For each 8-bit unsigned integer set (3) to (1) ^ (2) rotated right by const. This can be also be written as ( ( (1) ^ (2) ) >> const ) | ( ( (1) ^ (2) ) << ( 8 − const ) ). The rotate amount is limited to 1 ≤ const ≤ 8.
256-bit SVE

For each 8-bit unsigned integer set (3) to (1) ^ (2) rotated right by const. This can be also be written as ( ( (1) ^ (2) ) >> const ) | ( ( (1) ^ (2) ) << ( 8 − const ) ). The rotate amount is limited to 1 ≤ const ≤ 8.
512-bit SVE

For each 8-bit unsigned integer set (3) to (1) ^ (2) rotated right by const. This can be also be written as ( ( (1) ^ (2) ) >> const ) | ( ( (1) ^ (2) ) << ( 8 − const ) ). The rotate amount is limited to 1 ≤ const ≤ 8.
