------- Comment #6 from jakub at gcc dot gnu dot org 2009-02-18 18:56 ------- Would it be possible for known loop bounds to still use pointer etc. ivopts if we can ensure the overflow doesn't happen on that interval (+-1)? Say if the same testcase goes for (i = 16; i >= 10; i--) instead of for (i = 6; i >= 0; i--)?
