Examples:

	VMOV V13.B[1], R20      <=>      mov x20, v13.b[1]
	VMOV V13.H[1], R20      <=>      mov w20, v13.h[1]
	JMP (R3)                <=>      br x3
	CALL (R17)              <=>      blr x17
	LDAXRB (R19), R16       <=>      ldaxrb w16, [x19]
	NOOP                    <=>      nop

# Register mapping rules

1. All basic register names are written as Rn.

2. Go uses ZR as the zero register and RSP as the stack pointer.
