--- Comment #1 from nightstrike <nightstrike at gmail dot com> ---
Would this also be a missed optimization?  If the warning is saying that it
can't optimize a loop, and the warning is invalid, then if the loop is
optimizable but isn't being optimized.... would that qualify as a missed
optimization?
