--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed - mine. Note that SRA cannot decompose arrays but I see a lot
of missed CSE opportunities here which is because we unroll the loops
completely only very late and the only memory CSE pass after that is
DOM which is somewhat very limited here...
I'll try to improve that. Related to some other PR.
