Thanks for taking a look at this. I have extracted the patterns into an externally visible function, but I don't understand the benefit of splitting the two CFG conversion passes out into different files. I think this could be confusing because it would be unclear which file one should contain the definition of those conversion patterns. Keeping it in one file makes it clear that both do exactly the same thing on different target operations.
