// Something in code linked after this function is performing better with a +4 alignment.
// Adding this nop is causing the next function (_GLOBAL__sub_I_SD) to have an address with a last digit of 0x4.
// Last digit of 0xc also works.
// This affects both with and without XCVR, currently without XCVR doesn't need any padding.
// Until the culprit can be tracked down and fixed, it may be necessary to do manual adjustment.
