[PATCH] D146466: [clang] diagnose function fallthrough

[Eli Friedman via Phabricator via cfe-commits]

efriedma added a comment.

There are limits to how much we can do by just changing the code clang generates... but the two particular cases you mention probably could be "fixed" by messing with the IR generated by clang.  Sure, that probably makes sense to pursue.  (If you're going to pick an arbitrary value, zero is probably a better choice than "freeze poison".)
