As far as I know, there is not just a single report for all the 
information you are searching for, but there are various (internal) dump 
formats of intermediate representations, just check out the

-fdump-*

switches from the man page, e.g.

-fdump-class-hierarchy[-n]               for class specific information 
(including class sizes)


To get a whole bunch of internal dumps, you could use:

# gcc/g++ [options] -fdump-tree-all-raw -O2


The inline-specific dumps for example contain a lot of information about 
statically estimated function sizes/times.


I'm not sure what your plans are, but if you intend to build some 
scripts which analyze these internal dumps, please note that that the 
format is not standardized and could be changed from release to release.
