Re: m68k bootstrapping broken

that is of course correct, it was simply the first anomaly
in the rtl dumps that I have noticed so I am trying to see
where it comes from.
Oh, I didn't realize the code in question was actually one
of the differences between stage2 and stage3.
Just an idea: m68k is the only cc0 target capable of an
hosted bootstrap. Is it possible that middle-end changes
have subtly broken cc0 targets without anyone noticing
except on the m68k?
what is cc0?
It's described shortly here: <http://gcc.gnu.org/simtest-howto.html> .
The gccint manual contains the details.
