Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |NEW --- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> --- When interchange happens you should see sth like "loops interchanged in loop nest" when compiling with -fopt-info-loop. But it doesn't do that for the fortran case.
