--- Comment #2 from howarth at bromo dot med.uc.edu ---
Noticing that this bug seems similar to that fixed in
https://gcc.gnu.org/ml/gcc-patches/2011-07/msg00450.html, I puzzled out that
the following change allows the gcc.dg/graphite/isl-codegen-loop-dumping.c test
case to generate the expected dump file and pass.
