All Implemented Interfaces:
IRegisterBank
public class RegisterBankArm64 extends AbstractRegisterBank
Register bank for an ARM 64-bit (Aarch64, ARM v8) processor.

Note about GIC: the ICV_* registers have the same {op0, op1, CRn, CRm, op2} encodings as the corresponding ICC_* registers. For these encodings, GIC register configuration fields determine which register is accessed. Will use ICC.
