2 months ago so I used an llm to try to fix it lol (this makes llvm crate compile)

} // extern "C"did export LLVM_LINK_SHARED=1 and tried to compile but it seems rust attempts to use llvm objects that aren't there anymore..
well in llvm 18 you don't have passmanagerbuilder, so this won't work with modern llvm
