--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So this just happens to work on the trunk (and GCC 14 since switching over to
use LRA rather than reload; r14-383-gfaf8bea79b6256).
The problem is definitely how atomic_compare_and_swapsi is represented. Someone
will have to decide if it is a bug in reload or really a bug in how
atomic_compare_and_swapsi is represented in the microblaze backend.
Note reverting r14-383-gfaf8bea79b6256 for the microblaze part we can reproduce
it on the trunk.
