None.
Generates a shared object enabled for runtime linking.
The compiler automatically exports all global symbols from the shared object unless you specify which symbols to export by using with the -bE:, -bexport:, or -bnoexpall option. You can also prevent weak symbols from being exported by using the -qnoweakexp option. Symbols that have the hidden or internal visibility attribute are not exported.
To save the export list to a file, use the -qexpfile option.
