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,
