thanks for the response.

I am not sure that this is what I need. When and how should I call
After the FunctionPassManager is done, the calling ModulePass still
performs quite a few actions on the transformed code and also calls the
FunctionPassManager on different functions. However, I need to display
statistics about the transformation of each function separately.
If I call llvm_shutdown() after the FunctionPassManager is finished, I
do not get any output. Instead, the bitcode seems to get corrupted (at
least the verifier reports a lot of "Intrinsic has wrong parameter
attributes" warnings, the code still runs fine).
