<P>Hi Ana,</P>
<P>There are few issues in LoopInterchange which I'm working on so LoopInterchange is disabled by default. Hopefully those issues will be resolved shortly.</P>
<P>But as Hal and others had mentioned on mailing list some time back we will need to delinearize array references to do a correct data dependence analysis. So I'm OK with this change but will let more experienced people to give a LGTM.</P>
<P>Thanks and Regards</P>
