--- Comment #1 from Vladimir Makarov <vmakarov at gcc dot gnu.org> --- Thomas, it seems from your description the problem really exists. I tried to reproduce the problem with the test you provided but I've failed. I used today trunk. Could you provide more info (may be -mcpu/-march etc) or/and another test.
