Description

Using a virtual function in C++ requires an additional pointer to virtual function tables. The Compiler cannot access the pointer and generates the pointer in every class object when virtual function tables are associated.

Note: Specifying qualifiers not supported by the Backend or CPU has no effect (refer Backend).

Example

  -QvtpFar

This sets the qualifier for virtual table pointers to __far, which enables placement of the virtual tables into a __FAR_SEG segment (if the Backend or CPU supports __FAR_SEG segments).
