        * calls.c (maybe_warn_nonstring_arg): Punt early if
        warn_stringop_overflow is zero.  Don't call get_range_strlen
        on 3rd argument, keep iterating until lenrng[1] is INTEGER_CST.
        Swap comparison operands to have constants on rhs.  Only use
        lenrng[1] if non-NULL and INTEGER_CST.  Don't uselessly
        increment lenrng[0].

        * gcc.dg/pr87099.c: New test.
