- References: <20190829151347.13536-1-jose.marchesi@oracle.com>
The function integer_range_info makes sure that, if provided, the
initial value fills in the especified range. However, it is necessary
to convert the values to a numerical context before comparing, to make
sure awk is using arithmetical order and not lexicographical order.
gcc/ChangeLog:
* opt-functions.awk (integer_range_info): Make sure values are in
numeric context before operating with them.
