================
Comment at: llvm/tools/llvm-objcopy/CopyConfig.cpp:1013-1025
+ SmallVector<StringRef, 2> Positional;
+ for (auto Arg : InputArgs.filtered(BITCODE_STRIP_INPUT))
+ Positional.push_back(Arg->getValue());
+ // TODO: Add tests for these errors once we implement support for the
+ // tool-specific command line options. At the moment we do not reach these
+ // cases because of early returns.
+ if (Positional.empty())

another option is to call "exit(0)" - without these checks InputfFilename/OutputFilename can't be safely set, and without them one can not construct a valid instance of Config. Not sure if exit(0) inside the function which parses command-line options is better, but it doesn't matter much anyway. What's your preference ?
