None.
At link time, searches the directory path for library files specified by the -l option.
Not applicable.
Adds Directory to the list of search directories that are used for finding libraries designated by the -l flag (lowercase letter L). If you use libraries other than the default ones specified in /opt/ibm/xlf/15.1.0/lib or /opt/ibm/xlf/15.1.0/lib64, you can specify one or more -L options that point to the locations of the other libraries.
This option is passed directly to the ld command and is not processed by XL Fortran at all.
