    -L <lib-dir>     lib directory.
    -p <pass-name>   pass name.
    -o <output>      output file (prefix).
    -O <output-dir>  output directory.


    Note that if note directory information is provided, we will
    use current directory as the default one. If no file name
    is provided, we will search them automatically. If no pass name
    is provided, we will assume its name is just the library name
    by removing '.so' and 'lib'.
