Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|rguenth at gcc dot gnu.org |unassigned at gcc dot gnu.org Status|ASSIGNED |NEW --- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- -fno-split-loops makes both variants run at the same speed (but slower than with splitting loops). There are still some bogus profile counts/probabilities with that, notably after ifcvt and vectorization :/
