--- Comment #1 from Connor Abbott <cwabbott0 at gmail.com> ---
I sent a patch that should fix the assertion failures. I'm not so sure about
the performance regression, though -- to be clear, do you get it on other
platforms without the INTEL_DEVID_OVERRIDE? There are some things that could be
improved about the performance, since like the commit message says we're
calculating the livein/liveout sets unnecessarily, but if that's the reason
then I'd rather we not revert this patch just because of that.
