Isn't this a binutils rather than gcc issue ?

Pretty much.

Hi Josh Boyer,

just wanted to add that I'm experiencing the same problem that Robert
reported, but on 8xx instead of 4xx. The mpc8xx does not support the
mfdcrx instruction, so maybe it's more to it than just a binutils bug?

Best regards,
