--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed. It doesn't look like the assignment to left[i] affects the
determination of the maximum number of iterations of the loop during unrolling.
This is also a missed optimization opportunity since the whole loop could be
eliminated.
