--- Comment #13 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I can confirm this, even on current trunk.
The reason is that runtptests/3 -> tp_sum/5 is not inlined because it
exceeds max-inline-insns-auto. I have to set the param to 43 - the
default is 15 - for the function to be inlined and then the result is
fast again. In GCC 8 the value of the param was 30. After a very
superficial glance at the function in the release_ssa dump, the
function does not seem to be any bigger than in the gcc 8 times.

And if I looked into the testcase that is in the repo, I would have
discovered PR 88711 which is exactly about this. See Honza's comments
about the problem there.
(I'd prefer to keep that bug opened and close this one, but Honza
decided otherwise, so I'm changing the name because it not an IPA-CP
issue any more).
