Controls the generation of virtual function tables.
The default is to define the virtual function table for a class if the current compilation unit contains the body of the first non-inline virtual member function declared in the class member list.
Specifying -qvftable generates virtual function tables for all classes with virtual functions that are defined in the current compilation unit.
If you specify -qnovftable, no virtual function tables are generated in the current compilation unit.
To compile the file myprogram.C so that no virtual function tables are generated, enter:
xlc++ myprogram.C -qnovftable
