Yes, ultimately :).

Okay, I think I miss something.
What is the problem we are facing with IR to IR passes in llc?
Couldn't we just run them into opt?

I am missing something here too. Is Running llc on just specific passes supposed to work?

It seems like I completely miss the underlying problem.
The goal of this patch was to solve a dependency issue between two libraries.
If we want more, we need to go back to the discussion without any patch in mind.

Thanks,
