写一个新的jit [英] Writing a new jit

问题描述

我有兴趣在C ++中启动我自己的JIT项目。我不是不熟悉程序集或编译器设计等等。但是，我非常不熟悉的结果机器代码格式 - 像mov命令实际上看起来像什么时，所有的说，完成，是时候调用函数指针。那么，创建这样的东西最好的资源是什么？

I'm interested in starting my own JIT project in C++. I'm not that unfamiliar with assembly, or compiler design etc etc. But, I am very unfamiliar with the resulting machine code format - like, what does a mov instruction actually look like when all is said and done and it's time to call that function pointer. So, what are the best resources for creating such a thing?

编辑：现在，我只对Windows上的x86感兴趣，伸展一点点到64位Windows

Right now, I'm only interested in x86 on Windows, stretching a tiny bit to 64bit Windows in the future.

推荐答案

您想查看您感兴趣的架构的处理器手册。这些手册描述操作码编码。对于x86处理器，可以从此页面下载手册。

You want to have a look at the processor manuals for the architecture you are interested in. Those manuals describe the opcode encoding. For x86 processors, the manuals can be downloaded from this page.
