--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So it turns out we set LOOPS_MAY_HAVE_MULTIPLE_LATCHES a few places through the
compiling. BUT LOOPS_MAY_HAVE_MULTIPLE_LATCHES does not mean don't protect the
latch. It rather means the current state might have multiple latches but it is
best to protect the latches.
