Could you file a bug and attach the bytecode after 'opt -indvars -loop-rotate'? I would need that to determine why LoopInfo::getTripCount isn't returning any value. Nick

Hi, I am trying to add a new loop pass in which I making a call to get the trip count of the loop using Value *TripCountValue = L->getTripCount() However I am always getting NULL for TripCountValue (confirmed through gdb). I am running this pass after the canonicalization of induction variables: opt --debug-pass=Structure -stats -indvars -loop-rotate -my-loop-pass < main.bc >
