------- Comment #10 from rguenth at gcc dot gnu dot org  2008-03-15 12:40 -------
the nonoverlapping_memrefs_p check can be simplified (consolidated) by using
the generic get_ref_base_and_extent code.  The result of that can be adjusted
by MEM_OFFSET and only in case of an indirect base we may try to
disambiguate based on struct contain-ness of the types of that accesses.

Maybe I'll have a look, as this sounds uselful in general.
