这个错感觉是 fla 的问题啊，有什么解决方法吗

[buffcow]

这个错感觉是 fla 的问题啊，有什么解决方法吗

看着像是 -fla 命令识别不出来，应该是 clang.exe 文件没替换，只替换了 clang++.exe

[wuxiaojun123]

替换了clang.exe，clang++.exe，clang-cl.exe的，不使用 -fla 就能编译通过，看了这篇文章https://cyrus-studio.github.io/blog/posts/ollvm-%E7%A7%BB%E6%A4%8D-llvm18-%E8%B8%A9%E5%9D%91%E4%B8%80%E6%AD%A5%E6%AD%A5%E8%B0%83%E8%AF%95%E4%BF%AE%E5%A4%8D%E6%8E%A7%E5%88%B6%E6%B5%81%E5%B9%B3%E5%9D%A6%E5%8C%96/ 但是看源码是解决的啊，实际编译出来却不行

[buffcow]

有没有强制使用 legacy-pass , 其它 ollvm指令 能用吗

[wuxiaojun123]

其他的 ollvm指令能用，就fla不行，没有强制使用 legacy-pass

[buffcow]

其他的 ollvm指令能用，就fla不行，没有强制使用 legacy-pass

那我也不知道什么原因了，换其它版本的试试？

[wuxiaojun123]

https://github.com/CYRUS-STUDIO/LLVM 我是在这个版本基础上编译的，cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;lld" -DLLVM_TARGETS_TO_BUILD="AArch64;ARM" -DLLVM_ENABLE_ASSERTIONS=OFF -DCMAKE_INSTALL_PREFIX=install -DCMAKE_C_FLAGS="/utf-8" -DCMAKE_CXX_FLAGS="/utf-8" ../llvm 这是我的编译命令，是不是我的编译命令有问题？

[buffcow]

这个项目我没有编译过，我是直接跑 google 的 build.py 脚本编译的，官方 LLVM 和 google ndk llvm 有点出入

[AndroidMaster25]

I fixed the clang crash with the help of AI but this is not enough, the lib crashes if fla is applied. Here is the Flattening.cpp if you want to improve it
