--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
There's another PR where DOM shows up via ranger also at -O1 - does -O1 help
here?

In that PR I presented a prototype of limiting the dominator walk of ranger
which looks unbound (but I expected Ranger folks to pick that idea up).
See PR114855 comment#13.

Note DOM is the only user left of the forward jump threading.
