FWIW, I tried to build a simple cc0 target with LRA (v850-elf), but it
fell over pretty early.  Essentially LRA doesn't seem to be cc0-aware
in split_reg as ultimately inserted something between a cc0-setter and
cc0-user.  Oops.

Yes, that is true.  When I started to work on LRA, I decided to ignore
cc0 first.  But since then, no progress was made on this front.

No worries.


I guess the support of cc0 can be implemented for reasonable amount of
time.  It is just a priority issue.  I still have a lot PRs for the
targets already using LRA.

I wouldn't suggest making cc0 support a significant priority. I'd bemore likely to push for deprecating cc0 targets first.
