Understood. However, is it possible to just provide an option for the user to choose to just delete all the zero records and files in order to save more space? > > How exactly do you merge profiles? Do you run parallel invocation which can > take log2(N)? We run serial merge adding one at a time right now. Is it possible for gcov-merge to add a new functionality to automatically merge complete Set of subdirectories?
