--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is diagnosed in ira.c (ira_setup_eliminable_regset), but nothing is
actually changed in the IL.  I wonder if the RA shouldn't for the eliminable
registers that can't be eliminated couldn't delete the instructions or
something similar, so that we don't ICE during error-recovery later on.
