Hi Anna and Michael Zolothukin,

I have renamed the function and reduced the CHECK patterns in the testcase.
I have tried to keep the CHECK patterns generic.
I have retained the CHECK patterns for only 3 loops (the number of loops that would be generated with this revision) and the corresponding phi nodes at the exit (join) nodes.

One help: Is there a way to make the phi-nodes (in the CHECK pattern) more generic?

Thanks,
Abhilash
