Thanks for the response.<br>
I looked and I cannot see what exactly I need. I saw getCalledFunction() so I<br>
need CallSite CS(cast<Value>(II)) where II is a basic block iterator, so an<br>
instruction. It seems not easier than the "unelegant" version....if I am still<br>
at the Instruction level...<br>

the call graph gives you a graph where the nodes are functions, and there is an<br>
edge from function F to function G if function F calls function G.<div class="im"><br>

I need a method that takes from a "leaf" basic block from a function (Maybe<br>
there is the possibility not to have only one "end" basic block) the connection<br>
with an entry basic block of another function.<br>

Most functions don't end in a call to another function, they end by returning<br>
control to the function that called them.<br>

Hello,<br>
<br>
I try to make a big CFG (control flow graph) by combining all the CFG-s<br>
from all<br>
the functions of a module. I still have one problem : I want to get the<br>
links<br>
between functions.<br>
<br></div>
For CFG-s, I used CallGraphNode->second->__<u></u>getFunction, then<div class="im"><br>
Function_iterators<br>
and succ_iterators, so I have all the links between BBs. Now, the<br>
questions is<br>
how do I link BBs from different functions?<br>
<br>
I can do it in a way not so elegant. Take the last BB of every function,<br>
then<br>
getTerminator and see that function it is called and then link to<br>
(instruction-2-instruction).<br>
<br>
<br>
calls don't have to be terminators, so that wouldn't work properly anyway.<br>
<br>
<br>
<br>
There must be there a better way to get the linkage between BBs that are in<br>
different functions.<br>
<br>
<br></div>
Sure, take a look at include/llvm/Analysis/__<u></u>CallGraph.h<br>
<br>
Ciao, Duncan.<br>
