--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
On the gcc 12 branch we optimize the use of rprio away in DSE5 (which just
collects unused SSA names). The DOM3 pass via its EVRP use optimizes the
if (rprio != 1) check there which is what no longer happens on trunk.
So it's likely indeed ranger related.
