Options:
--invoke=<fn> name of function to run
-o, --optimize runs optimization passes on the translated functions
-c, --cache enable caching system, use default cache directory
--cache-dir=<cache_dir>
enable caching system, use specified cache directory
--cache-compression-level=<compr_level>
enable caching system, use custom compression level for new cache, values 1-21
-c, --cache enable caching system, use default configuration
--cache-config=<cache_config_file>
enable caching system, use specified cache configuration
--create-cache-config
used with --cache or --cache-config, creates default configuration and writes it to the disk,
will fail if specified file already exists (or default file if used with --cache)
-g generate debug information
-d, --debug enable debug output on stderr/stdout
--enable-simd enable proposed SIMD instructions
