--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Oh, the late sinking pass now undoes PHI-OPTs hoist_adjacent_loads - that's
ping-ponging already between phiopt2, sink1 and phiopt4. So the easiest
"fix" would be to re-schedule the added sink pass before phiopt4.
Of course having two transforms that work against each other in the compiler is
bad in the first place.
