    tree-optimization/108782 - nested first order recurrence vectorization

    First order recurrence vectorization isn't possible for nested
    loops.

            PR tree-optimization/108782
            * tree-vect-loop.cc (vect_phi_first_order_recurrence_p):
            Make sure we're not vectorizing an inner loop.

            * gcc.dg/torture/pr108782.c: New testcase.
