but the most trivial thing would be to feed the pass the balanced-tree generated by switch expansion where I would expect us to be able to detect it as the original switch again.
Well, if we want to support such matching, then please deffer it to a phase 2. I don't see it a common pattern that people write such a code in wild. Right now, we have some local analysis and one can eventually build a more advanced algorithm on top of it. Can we please make a progress for GCC 11 with the current approach that will cover quite some interesting if-chains? Thanks, Martin
