Why does this return a `bool`? If you want to know what happened, does it not make sense to return a `Status` object directly? Or an `llvm::Error` if that's your thing. https://github.com/llvm/llvm-project/pull/99814 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
