ioeric added a comment. `llvm::ErrorOr` carries `std::error_code`. If you want richer information (e.g. error_code + error message), `llvm::Expcted<T>` and `llvm::Error` are your friends.
FYI, if you only need error_code + error_message in the returned error, there is also `llvm::StringError`. And if you want to carry even more information in the errors, you can implement `llvm::ErrorInfo`, which is what we are doing in libTooling replacements library: https://github.com/llvm-mirror/clang/blob/master/include/clang/Tooling/Core/Replacement.h#L150 https://reviews.llvm.org/D27440 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
