是否有必要每台机器code只能映射到一个装配code？ [英] Is it necessary that each machine code can only map to one assembly code?

问题描述

假设这两个是essensially相同的：

Suppose these two are essensially the same:

push 1

和

0x1231

它说每一个汇编指令映射到一台机器code。

Which says each assembly instruction maps to a machine code.

但它是必要的，每台机器code只能映射到一个装配code？

But is it necessary that each machine code can only map to one assembly code?

推荐答案

MIPS汇编语言有几个伪指令。例如，移动是内部只是一个增加和一个隐含的$操作数为0。

MIPS assembly language has several "pseudoinstructions". For example, "move" is internally just an "add" with an implicit $0 operand.
