Constructor Argument Optimization in Object Model for Folding Multiple Casts Expressions

摘要

A method and computer program product, for providing an optimization for a most derived object during compile time are provided. The optimization determines whether a most derived class object is present during a compile time. Also, the optimization utilizes the most derived class object to obtain a location of a virtual base for the most derived class object during the compile time, and provides the virtual base of the most derived class object during the compile time. The method is executed for a constructor and/or a destructor. The constructor or destructor contains arguments which require conversion to a base type, and the conversion is performed at compile-time instead of at runtime.
