I am doing a CallGraphPass but would like to get the LoopInfo
of the functions inside this pass, is this possible? Currently I
have a function inside the CallGraph struct:<br>
<br>
void getAnalysisUsage(AnalysisUsage &AU) const {<br>
AU.addRequired<LoopInfo>();<br>
AU.addPreserved<LoopInfo>();<br>
}<br>
<br>
And later inside the pass I am calling:<br>
<br>
LoopInfo &LI = getAnalysis<LoopInfo>();<br>
<br>
I have also tried to pass the Function pointer to getAnalysis but
that doesn't work either. With the above code my error is:<br>

1) You may need to pass a Function pointer or reference if your pass
is not a FunctionPass (e.g., if it is a ModulePass).<br>
<br>
2) If you have to specify a Function pointer or reference, you need
to make sure that the Function is *not* a declaration:<br>
<br>
if (!(F->getDeclaration()))<br>
getAnalysis<LoopInfo>(F);<br>
