This should probably be an error if it's possible to unwind: it's effectively miscompile. Both here, and in the backend. Add a note suggesting marking the function `noexcept`/`__attribute((nothrow))`. If it isn't possible to unwind, you just end up with slightly inaccurate debug info, which is just annoying; probably not worth warning for that. https://github.com/llvm/llvm-project/pull/83301 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
