--- Comment #24 from Richard Biener <rguenth at gcc dot gnu.org> ---
GCC 8.4 and 9.5 take around 4s for me, GCC 10 and 11 about 10s, GCC 12 and
trunk are instant (0.2s). GCC 12+ has the backwards threader rewritten, that's
nothing to backport.
But at least fixed in 12+ sofar.
Nothing to do here anymore (not for Jeff either ;))
