--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Of course I wonder why the RA even chooses registers that are not available on
the architecture. I suppose there's no real way to turn regs on/off but the
way is to make them never match any instruction pattern and thus give RA no
incentive to use them? That is, why was kmovd %edx,%k0 deemed a valid
recognizable instruction?
