...to support such scenarios. That does not mean you can not use LoopInfo in your pass. It means, you'll have to manage the memory, satisfy its needs and ensure validity of the info yourself. You could do something like, LoopInfo LI; DominatorTree DT; .... DT.recalculate(F) LI.Calculate(DT.getBase()); ... ... use LI ... /* Make sure F is not modified since DT and LI were calculate. */ ...

In order to detect whether CallSite is present in innermost loop, do I need to insert logic from LoopInfo pass for collecting loops, within a CallGraphSCC pass?   Is there any other approach for this?   Regards, Pankaj -------------- next part -------------- An HTML attachment was scrubbed...

...sis frameworks (opt, etc.).  In what I am doing, I need to be able to access the dominator tree for a given function.  Is there a way I can instantiate a DominatorTree object outside the existing analysis frameworks? I have tried several things all along the lines of: DominatorTree DT; DT.getBase().recalculate(F); Everything I have tried results in an assertion failure when trying to access the front() of what I assume is the DominatorTree: Assertion failed: !empty() && "Called front() on empty list!"

Mmm I found out a very strange behavior (to me) of the SCEV analysis of the loop bound of the external loop I posted. When in ScopDetection it gets the SCEV of the external loop bound in the "isValidLoop()" function with: const SCEV *LoopCount = SE->getBackedgeTakenCount(L); It returns a SCEVCouldNotCompute, but if I change the "if" block inside the loop from: if
