Thanks for a quick look!

Also arguments of emit_move_insn must have the same integer modes.
if (reg_overlap_mentioned_p (operands[1], operands[2]))
std::swap (operands[0], operands[2]);
sh_check_add_incdec_notes (emit_move_insn (operands[2], operands[3]));
might ICE if operands[0] and operands[2] have different modes and
swap happens, though I'm not sure whether such insns are real or not.
