No objections from me - just wondering about the motivation: why would we
want to sort by symbol address?
Perhaps to see the overhead layout/distribution within a DSO, to better
cache-pack hot functions by placing them next to each other?
Putting a short usecase into the changelog (or even better, the
documentation) would be nice.
Thanks,
Ingo
