The same thing is with other way around. I.e.:

void ntoh(uint16_t idata, uint8_t *odata) {
    odata[0] = idata >> 8;
    odata[1] = idata & 0xff;
}

results with:

        move.l 8(%sp),%a0
        move.w 6(%sp),(%a0)
        rts

I've tried with both -mstrict-align and -mno-strict-align and there are no
differences in the produced assembly file (generated with -S).
