--- Comment #15 from Jan Hubicka <hubicka at gcc dot gnu.org> --- We run into the size estimate with always inlines because after inlining we update the size of caller (because that does matter when inlining normal functions). We already have special purepose always inliner to avoid some of the issues, so I guess we keep running into this during the late IPA inlining? Honza
