Does updating Callgraph result in updating icfg and pag?

[hadi81]

I am adding indirect callees for a callsite.

callgraph->getIndCallMap()[callsight].insert(calleeFun);
After doing this, I call updateCallGraph in CallGraph. ICFG, and SVFIRBuilder (PAG) will use updated callgraph to update their graphs with indirect calls.

Questions:
Will there be any effect on running points to analysis.

1. Will each of update results correctly reflected to points to analysis results?
2. In other words, after I update any of graph regarding indirect callee results, I want to make sure they are fully reflected in points-to analysis.
   For example, I think pag is the lowest-level result, icfg is the second lowest-level result, and callgraph is the highest-level result. If we simply update call graph and then have points-to analysis fully reflecting this call graph. That is fine. Otherwise, if some information is not reflected, I may need to update lower-level graphs (e.g., pag or icfg). In this case, I am wondering if I have to update pag --- not icfg or update all of these three graphs.
