128-bit SVE
Shift each unsigned 32-bit integer from (2) by the corresponding signed 32-bit integer from (1), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (2) << (1), otherwise it is ( (2) + ( 1 << ( −(1) − 1 ) ) ) >> −(1).
256-bit SVE
Shift each unsigned 32-bit integer from (2) by the corresponding signed 32-bit integer from (1), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (2) << (1), otherwise it is ( (2) + ( 1 << ( −(1) − 1 ) ) ) >> −(1).
512-bit SVE
Shift each unsigned 32-bit integer from (2) by the corresponding signed 32-bit integer from (1), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (2) << (1), otherwise it is ( (2) + ( 1 << ( −(1) − 1 ) ) ) >> −(1).

1024-bit SVE
Shift each unsigned 32-bit integer from (2) by the corresponding signed 32-bit integer from (1), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (2) << (1), otherwise it is ( (2) + ( 1 << ( −(1) − 1 ) ) ) >> −(1).
2048-bit SVE
Shift each unsigned 32-bit integer from (2) by the corresponding signed 32-bit integer from (1), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (2) << (1), otherwise it is ( (2) + ( 1 << ( −(1) − 1 ) ) ) >> −(1).
