alt Hacker NewsI think that is called specialization (https://www.linkedin.com/posts/compilers-lab_compiler-progra...).
Even if the compiler doesn’t explicitly do it, it can happen when doing subsequent optimization steps after inlining such as constant folding and dead code elimination.
Specialization is one of the reasons my call trees are just a little bit deeper than what one would expect given my loud but moderate stance on function splitting. Uncle Bob is nuts for espousing one line functions. But the answer to Bob being a lunatic is not two page functions. I think you can say a lot in five to six lines, and not overshoot meaningful names into word salad because you’ve run out of ideas. That’s still small enough for branch prediction, inlining, and specialization to kick in per call site, particularly if some callers follow one conditional branch and the others favors the other.
