--- Comment #15 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
My other idea was to pass bool ok to split_tree and if it sees that it cannot
negate_expr something, set it to false, so that we don't change the expression
after split_tree has been called. But if it worked I think I would've posted
the patch already.
