--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Guess the r16-5526 optimization needs to verify there is no partial aliasing,
so only either it is the same size/same address access, or disjoint accesses,
never partial.
Dunno how to ensure that, whether through alignment or only handling the case
mentioned from TSVC, e.g. ARRAY_REFs to the same array but different indexes,
something else?
