--- Comment #30 from Richard Biener <rguenth at gcc dot gnu.org> ---
With all the patches I have for now we end up with a pure IPA issue:

 phase opt and generate  : 193.97 (99%) usr  13.82 (93%) sys 207.75 (99%) wall
3311016 kB (94%) ggc

everything <= 1% dropped.  I wonder what that unaccounted todo is ;)
