I just realized that Kazu added a patch previously to
specify when a scratch registers is needed for H8300/H shifts,
and I think your code changes some of those assumptions.
See:
http://gcc.gnu.org/ml/gcc-patches/2002-06/msg00003.html
So, there may be some changes required for h8300_shift_needs_scratch_p()
to properly support the new modifications.
