--- Comment #4 from ⎓ ---
Hmm... I was hoping to get away with the readily available compiler, and I
thought that it's actually used for CPU32. Ok, I'll try then with a specific
one tomorrow.
But still, ABI can't request that all bytes in a uint

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)
