Hi Maxim,

Thanks for pointing me to this problem.

I would recommend that you disable the code in loop flattening by
early returning false in flatten_all_loops.  I'm pre-approving you to
commit such a patch (as I am not allowed to commit anything to gcc
due to my new employer's legal policies, although emailing or giving
instructions via a phone call to somebody of what to do seems to
be fine for now ;-)

Vladimir Kargov will take over where I left the patches to make graphite
work with ISL and once these are committed to gcc, we will be able to
implement loop flattening with ISL, by calling isl_map_flatten_range.
