It would be nice if -flto gave a report of what it did (differing from a plain compile and ordinary link), and if profiling said how much each change was worth. I expect that there would be some instances where the change could be expressed in the source code, and perhaps a case where increased developer understanding would lead to a change in implementation strategy. -- |
