Although we have made good progress toward that goal, we have not yet fully attained it, and it is likely that we never will. Consider a compiler. A sound compiler produces correct output for any input and never miscompiles your code; this is the fundamental expectation that every user should have of their compiler. An optimizing compiler produces code carefully chosen for speed without compromising on safety. Similarly, an inliner is a bit like an optimizing compiler whose goal is not speed but tidiness: inlining a call must never change the behavior of your program, and ideally it produces code that is maximally neat and tidy. Unfortunately, an optimizing compiler is provably never done: showing that two different programs are equivalent is an undecidable problem, and there will always be improvements that an expert knows are safe but the compiler cannot prove. So too with the inliner: there will always be cases where the inliner’s output is too fussy or otherwise stylistically inferior to that of a human expert, and there will always be more “tidiness optimizations” to add.
