@Eric, my analysis with #ifdef/#endif, the code size reduction is not very significant compare to how much of #ifdef/#endif we might need to guard like `sideband_msg_err`. Also, long back Aaron told me once to avoid guarding functions if its not getting executed then compiler would optimise it.

WDYT? just if clause is enough?
