Not specifically, no. If you invoke g++ with -v it will show you the full cc1plus command it runs, and you can run that yourself without the -quiet option, which (among lots of other information) will print the name of each function as it is compiled. > That would make it much easier to ensure that moves are done when they are > supposed to be. Moves will be done when they're supposed to be done, according to the rules of C++. If you mean moves are done when you *expect* them to be done that's a different thing, as your expectations may be wrong :-) What exactly are you worried about, the compiler failing to perform moves, or your code missing opportunities to move? The former will very rarely be a problem, the latter can be solved by understanding the language better.
