Unfortunately I messed up the choice of cost routines in the original patch.
I just committed the fix for that. The SH rtx_costs routine should now see
(set (reg) (reg)) and (set (reg) (const_int 0)) rtxes, so you should
be able to set the costs there. See:
http://gcc.gnu.org/ml/gcc-patches/2012-05/msg00425.html
for a similar MIPS patch.
