mksnaphost does not print usage when run with --help option.
// Print the usage if an error occurs when parsing the command line
// flags or if the help flag is set.
int result = i::FlagList::SetFlagsFromCommandLine(&argc, argv, true);
if (result > 0 || (argc > 3) || i::FLAG_help) {
::printf("Usage: %s --startup_src=... --startup_blob=... [extras]\n",
argv[0]);
i::FlagList::PrintHelp();
return !i::FLAG_help;
}
It seems to have intended to print usage here. but it could not reach line
258. because program will be exit in src/flags.cc:494.
if (FLAG_help) {
PrintHelp();
exit(0);
}
