You then combine the comparisons using the and instruction (note that you could have combined all the logical instructions into one with an xor, but the code would have been much less clear).
可以通过 and 指令进行组合比较（注意可以用一个 xor 将所有逻辑指令结合成一个，但那样做的代码应该比这个要清晰很多）。

If the size of the operand is not specified in the instruction, that means either that the size doesn't matter (as in logical instructions, for instance) or that it is using a 32-bit value size.
