Dear Utpal,

thanks for working on this. The general direction looks good. I leave the more detailed review to Johannes, Ether and whoever else has some input.

Best,

Please look at the comments and add some test cases as you did with the scopinfo function pass.

I am still not a fan of these lines and you introduce 2 of them in this patch. Could you remove them or do you think they really help?

assertion message seems odd.

And why cant we recompute dependences for the same SCoP? Isn't that what this function is all about?
