------- Comment #15 from jakub at gcc dot gnu dot org 2008-10-02 09:05 -------
Given that the cy vector is supposed to have 3 parts, the first for ivs, the
second for (optional) parameters and the last entry for constant column, and
av_for_af_base adds stuff to constant column and to the parameters, I'd expect
av_for_af means to write the ivs entries only, so the gcc_assert probably
should
even assert that var < AM_NB_INDUCTION_VARS (am). access_fun is
{0B, +, 4}_9 and AM_LOOP_NEST_NUM (am) == 1, which is far more than the 2 ivs
we have allocated space for.
