Applied the few changes. And yes, there will be iterations on this. For
example, merge-exit pass is not completely finished, and other specific
scenarios. But this will be done through smaller PRs.
I also need to look into how to test this since people want me

Ok, so I've figured out 3 issues:
1. A bug in my sorting of merge instructions. If LHS == RHS, I returned LHS <

Thanks for looking into this.
