难道Mono.Cecil能做到照顾分支机构等的位置？ [英] Does Mono.Cecil take care of branches etc location?

问题描述

那么这个问题可能看上去很奇怪，但它的简单 - 我的意思是，如果我有一个GOTO（brtrue等）的反编译code像例如

Well this question may seem odd but its simple - my point is if i have a "goto" (brtrue etc) in the decompiled code like example

br IL_0003
call *****
IL_0003: ret

和我添加命令后的 * 的*通话将BR顶部点沤像它应该或者是code。

and i add a command after that ** call will the br at the top point to ret like it should or to that code.

不塞西尔去做自己或我必须采取所有这些分支的照顾？ ：/ 它不会是很难解决这些问题，但如果塞西尔犯规的话，我根本不会启动这个项目，我已经没有时间（或知识）的高级IL魔法：P

does Cecil do it by itself or i have to take care of all those branches ? :/ it wouldnt be very hard to fix them but if Cecil doesnt then i simply wont start this project, ive no time (or knowledge) for advanced IL magic :P

PS。抱歉，如果即时通讯混乱的东西，但即时通讯在.NET中的东西一个初学者; /我是八方通通过其击退同Java或任何有一个虚拟机TBH

PS. sorry if im confusing things but im a begginer in .NET stuff ;/ i was allways repulsed by it same as Java or anything that has a VM TBH.

*（是的，我知道这不会是IL_0003它只是举例）*

*(yes i know it wont be IL_0003 its just for example)*

推荐答案

是的，丝丝将更新分支你。

Yes, Cecil will update the branch for you.

你要好好照顾，唯一的情况是该分支是一个短期形式的分支的情况。如果注入太多的说明，它可能会溢​​出。

The only case you have to take care of, is the case where the branch is a short form branch. If you inject too much instructions, it might overflow.

有一个非常简单的方法来处理这​​个问题。注射前code，只需调用扩展方法从Mono.Cecil.Rocks SimplifyMacros，像这样的：

There's a very simple way to handle this. Before injecting code, simply call the extension methods SimplifyMacros from the Mono.Cecil.Rocks, like this:

method.Body.SimplifyMacros ();

这将会把br.s变成BR

This will turn the br.s into br.

当你完成注入code，只需拨打：

And when you're done injecting code, simply call:

method.Body.OptimizeMacros ();

哪个是相反的操作，即，它将尝试把BR成br.s如果可能的话。

Which is the opposite operation, that is, it will try to turn br into br.s if possible.
