--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Started with r14-2944-g3d48c11ad082def8ee237e5778d8a5d569bff96d a is -1, so the testcase shouldn't do much except almost empty loops with a few iterations. The continue in there seems to be important, but dunno why, it is effectively just a goto to the immediately next statement; perhaps the continue predictor affects it?
