Building Supergraph (at call graph level)

[Virender Kashyap <virenk at cse dot iitb dot ac dot in>]

Hi,
         My question is based on new developments in tree-profiling brach.
  Assumption : we are working in unit-at-a-time mode.
     I see that cfg is maintained individually for a fuction. Does that 
mean that this cfg and other relavent information will be stored 
somewhere, before parsing of next function starts. And can i access all 
thse CFG's at one point (say after parsing is finished and i have built 
the call graph) ?
   Basically i want to build a supergraph, and  since the call graph 
already has lot of information, all i need to do is add CFG info to each 
node and my work shall be nearly done.
   One problem here is that CFG's are built after callgraph has been 
formed. It might be a good thing for me to do CFG consturction as soon 
as i have gimplified a funciton, and store this CFG in callgraph.

Any suggestions/ideas on this. I am asking because i may be missing on 
something.


Thanks and Regards.
