I wrote an inliner once. It might seem like an easy problem, but a proper inliner is a rabid animal you can just barely restrain on a leash.

The simple part is making it work without clashing. The hard part is making inlining always be an optimisation with reasonable code growth with regards to compilation time and cache use.

That sounds tough. You also have a code size/speed trade off that must be managed. Where did yours land?
