Hi Ian,
I don't see why:
http://gcc.gnu.org/ml/gcc-patches/2006-02/msg02031.html
was a bad thing. i think gcc would have been better if it had just
been committed.
Not fair. Zack himself says the patch is not recommended for commit,
and it just a baseline for further work. For this kind of target
specific change, I think it is best to let the target port maintainers
make the call. I've CC'ed the maintainers listed for h8. Perhaps
they will take a look at it.
I am aware of the define_constraints patch. I am thinking about working on
the H8 and M68K ports at least. How urgent is this? FWIW, I've reproduced
the ICE that Zack mentioned, but I haven't investigated it.
