Examples:

	MOVD.P -8(R10), R8         <=>      ldr x8, [x10],#-8
	MOVB.W 16(R16), R10        <=>      ldrsb x10, [x16,#16]!
	MOVBU.W 16(R16), R10       <=>      ldrb x10, [x16,#16]!

3. Go uses a series of MOV instructions as load and store.

64-bit variant ldr, str, stur => MOVD;
32-bit variant str, stur, ldrsw => MOVW;
32-bit variant ldr => MOVWU;
ldrb => MOVBU; ldrh => MOVHU;
ldrsb, sturb, strb => MOVB;
