Hi Wojtek, This is a great start. I'll focus and try to understand your interface design and choices. Here are my initial thoughts based on a quick read. The only interface provided by LoopMemDepAnalysis is "bool carriesDependence()" which may not be sufficient. But we can extend this. The ArrayDepTest provides testDependenc() as well as testPositions(). I'm not very clear about the testPositions(). Would it be possible for you to explain this ? One nit-pick, I see that some...

We want to model this as an analysis and make following changes. - Rename LoopMemDepAnalysis as DataDependenceAnalysis. Various transformation passes will use this interface to access data dependence info. This is an external interface. Put this in include/ llvm/Analysis. - Make DirectionVector (and later on DistanceVector) independent interface and put them in ADT. - Put various t...

Sure. For now, I am posting it as an attachment, because it does not build against the current SVN version. It is really basic (for example, it cannot produce distance vectors,

Wojtek, Please see David's message below. Have you or can you check in your code, perhaps as a project for now? That will allow us to start looking at it and perhaps collaborating on it. --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Aug 20, 2008, at 3:05 PM, David Greene wrote: > On Wednesday 20 August 2008
