--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The existing support for comparing addresses in operand_equal_p cannot handle
this as the volatile array is local.
It seems to me that there is no good reason to ever treat addresses of
TREE_SIDE_EFFECTS trees as different if there is not TREE_SIDE_EFFECTS
on offset determining pieces (though that would rely on gimplification
for COMPONENT_REFs?).
I wonder if this is the right time to introduce gimple_op_equal_p (),
wrapping operand_equal_p but handling a few cases less conservative...
