I agree though that the result is unfortunate - @erichkeane had pushed back on some other warnings similarly getting swallowed during review.
I wonder if we're taking the wrong approach here - we could also leave both of these warnings as "runtime only", and separately try to diagnose during constant evaluation. If that could work, it might make it easier to e.g., only diagnose overflow in a branch of a compile-time conditional if it's actually evaluated (which GCC seems to manage to do). https://github.com/llvm/llvm-project/pull/89565 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
