------- Comment #1 from dberlin at gcc dot gnu dot org 2007-04-29 16:05 -------
PRE optimized the "offset" and "stride" variables.
SCEV doesn't know how to create an offset or step out of these optimized
operations. We used to at some point, but I believe these are "peeled_chrec's"
that we removed support for before merge.
I think it's time we add back support for these chrec's. I can't block PRE
from optimizing these variables easily.
