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

Actually, there is a way to get what you want, if you can get your compiler to produce DWARF debugging information. There will be a DWARF description for each out-of-line function and within that description there will (hopefully) be entries for each inlined function. It's not trivial to read DWARF, and sometimes compilers don't produce complete or accurate DWARF, but it can be a useful source of information about what the compiler actually did, that's not tied to any one compiler or CPU. Once you have a DWARF reading library there are all sorts of useful tools you can build around it.

Don't expect to use it with Visual C++ as that uses a different debugging format. (But you might be able to do similar queries through the debug helper library that comes with it.)
