--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is an expansion issue not taking into cost of expanding using shifts
rather than test/set.

I am still working in this area and might improve this for GCC 14 but still
deciding on how to get some good infrastructure for the cost modeling ...
