How do I find how C++ compiler implements something except inspecting emitted machine code?

Question

Suppose I crafted a set of classes to abstract something and now I worry whether my C++ compiler will be able to peel off those wrappings and emit really clean, concise and

Answer 1

If your compiler manages to translate your "wrappings and emit really clean, concise and fast code" the effort to follow-up the emitted code should be reasonable.

Contrary to another answer I feel that emitted assembly code may well be "clean" if it is (relatively) easily mappable to the original source code, if it doesn't consist of calls all over the place and that the system of jumps is not too complex. With code scheduling and re-ordering an optimized machine code which is also readable is, alas, a thing of the past.
