如何将已经编好的C语言程序改写成汇编语言?

keil里可以直接转换，位置就在你仿真以后的代码转换里。

在KEIL环境下运行仿真，自动生成汇编代码，全部复制就可以了
但你不一定能看得懂

ID:776149 发表于 2020-6-11 22:05

C语言在编译过程中确实会产生汇编.s文件，但那个很乱，机器读的，一看就不是汇编写的，我做过一个类似的程序，但这个工作量对我太大了，建议楼主还是去找汇编的程序，不过现在用汇编写的人很少了，就我读书的时候学过，

ID:584814 发表于 2020-6-2 22:09

标记一下看看有木有后现代雷锋

ID:123289 发表于 2020-6-2 21:34

汇编程序KELL会自动生成的，无需要人为改写。只是你不知道它在那里而矣。你找找吧。
