--- Comment #6 from Allan Jensen <linux at carewolf dot com> --- Great. Your patch worked with 90% of the marked loops! The remaining report things like this with -fopt-info-vec-missed: note: not vectorized: relevant stmt not supported: idisty.872_437 = (unsigned int) idisty_386; note: bad operation or unsupported loop bound. But the result is already pretty good for -fopenmp with manually marked loops.
