That will help -- if the address is associated with a symbol.
For stack and heap pointers it's not always helpful.

I don't think there is a single command to do what you want, 
but "info target" will be helpful -- it will show all loaded
sections and their memory ranges.  You can fit the address into
one of them (if it fits).  "info file" is an alias for this
(I think).

This shows the sections for shared libraries too, which is a plus.


Maybe if you can mock up a spec for what it is you want, 
it wouldn't be that difficult to implement a new command
for it...
