--- Comment #37 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Fixed on the trunk so far, temporarily by differentiating between < 4KB
addresses which are still handled like GCC 11 did for warning purposes, and=
 >=3D
4KB addresses where we won't warn anymore.
For GCC 13 there is a plan for more complete solution.=
