--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
For the second testcase, I think we could in undefined_shift_range_check or its
2 callers intersect the value range of the last [lr]shift operand with the
range of [0, prec-1], and if that yields empty range, do what we use right now,
but if it narrows the op2 range to something smaller, use that in the
range_operator::fold_range call instead of op2.
