commit r14-3296-gdc48d1d1d4458773f89f21b2f019f66ddf88f2e5
Author: Andrew MacLeod <amacleod@redhat.com>
Date:   Thu Aug 17 11:13:14 2023 -0400

    Fix range-ops operator_addr.

    Lack of symbolic information prevents op1_range from beig able to draw
    the same conclusions as fold_range can.

            gcc/
            * range-op.cc (operator_addr_expr::op1_range): Be more restrictive.

            gcc/testsuite/
            * gcc.dg/pr111009.c: New.
