hook_add_new bug

[tianxingsky]

emulator.getBackend().hook_add_new(new InterruptHook() {
@OverRide
public void hook(Backend backend, int intno, int swi, Object user) {
int syscall=backend.reg_read(Arm64Const.UC_ARM64_REG_W8).intValue();
if(syscall==215)

                long address=backend.reg_read(Arm64Const.UC_ARM64_REG_X0).longValue();
                long len=backend.reg_read(Arm64Const.UC_ARM64_REG_X1).longValue();
                System.out.println(" hook_add_new :  "+intno+"    "+swi+"　address: "+Long.toHexString(address)+" len:　"+Long.toHexString(len));
            }

} 寄存器X0 取值为0 不正确
