--- Comment #2 from Jan Beulich <jbeulich at suse dot com> --- Hmm, both in 2.41 and in master I'm seeing "operand size mismatch", not "unsupported instruction". That's still not ideal, but imo quite a bit better. Yet I'm at a loss to explain why I would see a different error message than you do. Then again I'm also uncertain I properly understand your complaint: The title says "wrong number of registers" when from description and the gcc bug I'd rather infer "wrong register numbers". -- You are receiving this mail because: You are on the CC list for the bug.
