--- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> 2010-12-12 23:55:24 UTC --- With -O2 during early optimization we get to 68% in cgraph_check_inline_limits. This is weird since early inliner should not be terribly sensitive to this. I guess it is because we end up walking very long edge lists. I will check if I can do something here. Honza
