Hello, Clang is used before LLVM to generate IR, and is it possible to use it in a reverse way, i.e., after running LLVM passes, we can run clang again to use LLVM pass results? If so, should I write clang functions in LLVM passes, or write LLVM pass requirements in clang? Thank you in advance!

However, LLVM can output using the C back end ... which you can then feed into Clang.
