Hi Jan-Benedict,
With my re-started testing efforts, I've got another one for you I
guess (`./configure --target=v850-elf && make all-gcc`):
../.././gcc/config/v850/v850.c: In function ‘char*
construct_restore_jr(rtx)’:

I could not reproduce these in my local environment, but I suspect that
you are using a more recent version of gcc than me. The fix looks
obvious
however, so please could you try out the attached patch and let me know
if it resolves the problem ?
I suspect that construct_save_jarl has the same problem and the same
patch should fix it.
