The function added_clobbers_hard_reg_p is a generated function.  So
another approach would be some sort of attribute which directs the

This definitely sounds like the best approach for my specific case. I understand that for such a change to be integrated in GCC there might be other implications due to the vast number of different backends supported by GCC.

Thanks,
