[LLVMdev] Loop Trace

[Hanbing Li]

Dear All, 

Now I have a container like this: DenseMap<const Loop *, int> D, so means that for each loop, it has a corresponding number. But for some optimizations, the LoopInfo will change, and with the new loop, can I still get the number? As I tried, the answer is no. 
So my question is: 
Am I right?(can’t find the number by using D.find(newloop)) 
Is there a method to solve this?(maybe update the loopinfo in DenseMap......or some method else) 

Thank you 
Regards,
