------- Comment #3 from steven at gcc dot gnu dot org 2005-10-12 20:58 -------
The patch mentioned in #2 is not sufficient anymore. copy propagation and VRP
also propagate copies of this kind. And may_propagate_copy is not used in most
places, and even when it _is_ used, it doesn't help because it allows this kind
of copies to be performed.

Mark, this is probably not fixable for GCC 4.1.

------- Comment #5 from mmitchel at gcc dot gnu dot org 2005-10-30 22:41 -------
To better support restrict, we should copy around the set of "based on"
pointers when copying other pointer attributes.
However, I don't think this is a sufficiently serious missed optimization to
warrant holding up a release.
Downgraded to P5.

This is effectively a dup of PR14187. We fail to track what pointers are
based on a restrict pointer.
