# Class: com.pnfsoftware.jeb.core.units.code.asm.processor.arch.RegisterBankArm64

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.
