对于以上的问题，我没有任何头绪，我只知道ollvm 9.0.1版本移植到r22b是可以正常编译的，编译参数可以随便添加。ollvm12.0.1版本添加任何混淆参数都会报出上面类似的错误，我不知道是不是llvm版本的原因还是pass的原因。

[bluesadi]

看不出来是什么问题，不过NDK r22b用的LLVM版本是LLVM 11，把LLVM 12移植到r22b上大概率会出问题。OLLVM 9.0.1能移植成功属于是运气好，最好还是同LLVM版本移植。

[lbwengineer]

我在这里找了一个ollvm的pass：https://github.com/o2e/OLLVM-9.0.1 然后我添加-mllvm -fla编译选项，能够编译通过，并且混淆有效，但是这个项目的fla选项就会导致编译失败，你可以看看是什么原因。

而且我把上面的pass移植到你的项目里编译后可以正常混淆的，原来的fla选项就会编译失败，不知道是什么原因。

好的，我过几天看一下

我也是一样 咋修复？
