[PATCH] [RFC] Loop Interchane Pass

[hfinkel at anl.gov]

> After this step the loop is interchanged. It gives the correct results for few of the sample loops which i checked but I'm not sure if this is the right way to perform interchange transform. I suppose i will have to update the dom tree etc?


The method sounds reasonable (as James pointed out, I think there might be a simpler implementation). You only have to update the domtree if you claim to preserve it (same with LoopInfo, for example).

> Is it ok if i move the updated patch to llvm-commits mailing list for further review?


Yes, please do. You should have done this from the very beginning (and subscribed llvm-commits to this review, unfortunately, none of the (fairly extensive) comments here were mirrored to the list).
