I'm not laying words into your mouth, but I know you and I read
the subject of your mail and I read the IRC messages that you
were quoting. Those are pretty condescending which is really annoying.

Yes, a bug in the m68k kernel. Which means something that needs
to be fixed, irrelevant whether you're hosting this on a 32-bit
or a 64-bit machine.

What do you mean by consistency, you are using the wrong word.

There might be an issue with miscompiled code, but this would be
rather an issue with gcc than with the emulating environment.

Yes, qemu-m68k has some bugs. But those can be ironed out and
the best way to do it is to start actually using it and obeserve
the results that it produces. I have used the same approach to
get gcc-4.9 and gcc-5 fixed on sh4, with great success. And
Laurent is doing an awesome job fixing the bugs and I am glad
I am able to help him with some minor patches even though I
am new to the qemu codebase.

Once the bugs are ironed out, we have a massive speed advantage
which will eventually mean that we will be finally be able to
catch up, even with release architectures. And that is really
worth all the hassle and the bugs.

See, again, you're being condescending. This sentence alone
is complete non-sense. And, no, I am not going to use this
as an initiative to start a flamewar. The fact that Linux
is massively more successful than any flavour of BSD is enough
justification we need.

I don't think it's subjective. It's clearly the right approach
to improve things and not remain standing at the same point
in development forever. Time moves on and even Jordan Hubbard,
the *co-founder* of FreeBSD agrees with this stance:

I have done the same for *both* sh4 *and* sparc64. So?
