usage: llvm-autotune [-h] {minimize,maximize,feedback,dump,finalize} ...

positional arguments:
  {minimize,maximize,feedback,dump,finalize}
    minimize            Initialize tuning and generate the initial compiler
                        configuration file, aiming to minimize the metric
                        (e.g. run time)
    maximize            Initialize tuning and generate the initial compiler
                        configuration file, aiming to maximize the metric
                        (e.g. throughput)
    feedback            Feed back performance tuning result and generate a new
                        test configuration
    dump                Dump the current best configuration without
                        terminating the tuning run
    finalize            Finalize tuning and generate the optimal compiler
                        configuration

optional arguments:
  -h, --help            show this help message and exit
