[Bug tree-optimization/34172] Missed store ccp optimization



------- Comment #1 from rguenth at gcc dot gnu dot org  2007-11-21 12:04 -------
Note that only store _copyprop_ was removed for now.  But yes, store ccp
removal
is on the plate.  Note that this and similar bugs should be fixed by extending
value-numbering to disambiguate memory accesses itself and not only relying on
virtual operands.

Confirmed.
