--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
IPA PTA (the PTA solver in general) is a known hog, it got significantly worse
for testcases involving a lot of calls with Honzas re-org to improve PTA around
calls.
My suggestion is to not enable -fipa-pta if you hit such issue or in general if
you don't know it pays off with a good runtime performance boost.
