128-bit SVE
Shift each signed 64-bit integer from (1) by the corresponding signed 64-bit integer from (2), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (1) << (2), otherwise it is ( (1) + ( 1 << ( −(2) − 1 ) ) ) >> −(2).
256-bit SVE
Shift each signed 64-bit integer from (1) by the corresponding signed 64-bit integer from (2), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (1) << (2), otherwise it is ( (1) + ( 1 << ( −(2) − 1 ) ) ) >> −(2).
512-bit SVE
Shift each signed 64-bit integer from (1) by the corresponding signed 64-bit integer from (2), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (1) << (2), otherwise it is ( (1) + ( 1 << ( −(2) − 1 ) ) ) >> −(2).

1024-bit SVE
Shift each signed 64-bit integer from (1) by the corresponding signed 64-bit integer from (2), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (1) << (2), otherwise it is ( (1) + ( 1 << ( −(2) − 1 ) ) ) >> −(2).
2048-bit SVE
Shift each signed 64-bit integer from (1) by the corresponding signed 64-bit integer from (2), rounding if shifting right, setting (3) to the result. If (2) ≥ 0, the result is (1) << (2), otherwise it is ( (1) + ( 1 << ( −(2) − 1 ) ) ) >> −(2).
