Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I see a problem in the OpenMP lowering, that said, I hope you know that your testcase doesn't compute the minimum from all iterations, but just the last few ones (without -fopenmp just the last one, with -fopenmp from one to vectorization factor of the loop). So the value you get doesn't make any sense.
