WebFirst, note that the machine code, on the left, is all in one uniform-sized block of binary data, not ragged like x86 machine code. This is because ARM is a "Reduced Instruction Set Computer (RISC)" machine, while x86 is a "Complex Instruction Set Computer (CISC)" machine. RISC refers to the fact that every ordinary ARM instruction is a uniform 32 bits …

WebJan 9, 2015 · As CMP behaves exactly the same way SUBS does, except that the result is not saved in any register, the first mentioned method is probably the best. The second method is the one I prefer. I prefer it, because I tend to imagine a 'greater than' or 'less than' character between the two operands.
