Don't think we need to include all these details. Lets rephrase it to: ```suggestion** // FIXME: We should emit a trap message for this case too. But sometimes Clang will emit a ubsan trap into the prologue of a function, at which point the debug-info locations haven't been set up yet and can't hook up our artificial inline frame. ``` https://github.com/llvm/llvm-project/pull/145967 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
