[LLVMdev] Anomaly with CallGraph construction
...CalledFunction(CS, getOrInsertFunction(Callee));

While analyzing the IS NAS Parallel Benchmark I find the following BasicBlock:
; <label>:24 ; preds = %20
%25 = call double (...)* bitcast (double (double*, double*)* @randlc to double (...)*)(double* %t1, double* %t1)
store double %25, double* %t2, align 8
br label %26
As can be seen, the first Instruction after the label contains a call to randlc(). However, this gets counted by CallGraph as an external node, since
@randlc has been bitcasted and CS.getCalledFunct...

Hi Gabriel,

the reason that the callgraph analysis does not try to understand indirect
calls like this is that other passes are supposed to sort such things out
if they can be sorted out. If they failed then there is no point in having
the callgraph analysis try too....
