             Bug #: 14084
           Summary: --help shows -time and -print-stats; yet, driver does
                    not recognize them
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux

Neither the -time or -print-stats flag is recognized by the driver
even though both appear in the --help output:

make compiler_help_driver MAIN=test
/home/evansl/download/llvm/svn/install/bin/clang --help|grep -e ' -time\|
-print-stat'
  -print-stats            Print performance metrics and statistics
  -time                   Time individual commands
/home/evansl/download/llvm/svn/install/bin/clang -time -print-stats -c test.cpp
clang: warning: argument unused during compilation: '-time'
