Sorry, I'm late to the party here (I was about halfway through implementing this myself before I found this). I'd also like to understand why a separate pass is needed. For the epilogue in the middle of a function problem, why are save/restore CFI instructions not sufficient? Can you elaborate on the problem in TailDuplication?
