128-bit SVE
For each 64-bit unsigned integer set (3) to (1) + ( (2) + ( 1 << ( const − 1 ) ) >> const. This is the same as a regular shift, but with result incremented if the most-significant bit that was shifted out was set. The shift amount is limited to 1 ≤ const ≤ 64.
256-bit SVE
For each 64-bit unsigned integer set (3) to (1) + ( (2) + ( 1 << ( const − 1 ) ) >> const. This is the same as a regular shift, but with result incremented if the most-significant bit that was shifted out was set. The shift amount is limited to 1 ≤ const ≤ 64.
512-bit SVE
For each 64-bit unsigned integer set (3) to (1) + ( (2) + ( 1 << ( const − 1 ) ) >> const. This is the same as a regular shift, but with result incremented if the most-significant bit that was shifted out was set. The shift amount is limited to 1 ≤ const ≤ 64.

1024-bit SVE
For each 64-bit unsigned integer set (3) to (1) + ( (2) + ( 1 << ( const − 1 ) ) >> const. This is the same as a regular shift, but with result incremented if the most-significant bit that was shifted out was set. The shift amount is limited to 1 ≤ const ≤ 64.
2048-bit SVE
For each 64-bit unsigned integer set (3) to (1) + ( (2) + ( 1 << ( const − 1 ) ) >> const. This is the same as a regular shift, but with result incremented if the most-significant bit that was shifted out was set. The shift amount is limited to 1 ≤ const ≤ 64.
