It seems that there is some misunderstanding about my previous post. The purpose was never for measuring C++ performance but for better understanding of how polymorphism is implemented in C++, and make people aware that those extra power is not come for free. This is why I choose trivial cases and disable compiler optimization. Trivial [...]
One of the most useful and interesting features in C++ is virtual function. With the feature we are allowed to postpone determining the behavior of an object till run time. This gives us great flexibilities as we now are able to think of an object in terms of what category of types it belongs to, [...]
Sometimes we want to see the assembly code generated from a piece of C++ code. It could be very helpful for:
Better understanding about how compiler optimize our code
Better understanding about the dark side of the programming language that we are using to avoid the pitfalls.
Finding performance hints.
Debugging really tricky defects.
And I [...]
