FWIW, I tried to build a simple cc0 target with LRA (v850-elf), but it

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 be
more likely to push for deprecating cc0 targets first.
