--- Comment #2 from Sebastian Pop <spop at gcc dot gnu.org> ---
This part is not affine: {0, +, {1, +, 1}_1}_1
This is a polynomial of degree 2.
Are you sure the scev analysis reports this as affine?
I was trying to understand from the fortran code which part this scev comes
from...
and I think it comes from the NKL counter that gets incremented in the inner
loop,
counting the number of iterations of both loops, so it has a quadratic
evolution.
