--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
(In reply to Richard Biener from comment #6)
> 4.9 at -Os takes 5min and ~2.2GB of ram (points-to takes 20%, DF 33%)
trunk at -Os takes 15min and ~2.1GB of ram (dominator optimization takes 67%)
trunk at -O1 takes 14min and ~2GB of ram (still DOM at 62%)
So it seems that on trunk DOM regressed a lot. Confirmed as 4.10 regression.
