Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|tree-optimization |testsuite --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- We now vectorize this there correctly, also on x86_64 with -march=corei7. The testcase was added for a fixed miscompile which should have added a runtime testcase instead. I will add a { target { ! vect_perm } } but I suppose given this dg test it might still get us false positives/negatives.
