Hello,

The branch relaxation stuff on SH has been broken for a while.  A while
ago PRs and patches have been submitted but never applied, it seems.
Attached is the patch by Takashi Yoshii that fixes PR 10378.
Tested with 'make' for target sh-elf.
make check RUNTESTFLAGS="--target_board=sh-sim" looks OK, too.

Cheers,
Oleg
