Yes, I've fixed that bug just before sending the patch to Toon.  I
committed it to the graphite branch:
http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=130940

Agreed.

One of the reasons I didn't proposed the loop distribution before is
that I knew it was buggy, so I preferred to fix the bugs first and
then ask for inclusion when I was confident enough of its stability.
I believe it is now stable enough, as Toon shown with his experiment
on HIRLAM and with my tests of SPEC Cpu2000 and Cpu2006.
