I was going to suggest removing the support for emitting the version under the run subcommand, but I don't see it in llvm-lto2.cpp. Is that coming from somewhere in cl::ParseCommandLineOptions?

Hi Teresa,

It seems that llvm-lto2 run uses cl::ParseCommandLineOptions. This calls initCommonOptions() in CommandLine.cpp instantiates a CommandLineCommonOptions struct, where there is a VersionPrinter option and function. So taking it out or changing that workflow would impact other uses of cl::ParseCommandLineOptions.
