--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
We fail to warn in f2 because we compare the expression in the conditional
sequentially, but that doesn't work due to left-to-right associativity: we
compare
i == 0 with i == 1
and then
i == 0 || i == 1 with i == 0.
The fix would probably be to keep [low, high] pairs for every comparison and
then compare the pairs.
