Use this option to generate runtime type identification (RTTI) information for exception handling and for use by the typeid and dynamic_cast operators.

where available suboptions are:
rtti | The compiler generates the information needed for the RTTI typeid and dynamic_cast operators. |
nortti | The compiler does not generate RTTI information. |
For best runtime performance, suppress RTTI information generation with the default -qnortti setting.
The C++ language offers a (RTTI) mechanism for determining the class of an object at run time. It consists of two operators:
A type_info class describes the RTTI available and defines the type returned by the typeid operator.
You should be aware of the following effects when specifying the -qrtti compiler option:
