Yep, it is something with the last Richi's patch. Things has worked reosnably well for me prveiously (through not quite sanely - 94% of WPA time went into type merging. Good news is that we could hope for really huge speedup fixing this relatively small part of compiler) I will try to revert it too and look into inliner dumps on kernel just if I can spot something obvious.
