Mach-O binary format is challenging because it uses bit fields structs and the compiler switches the direction of bit fields on big vs little endian archs!</div><br><div>That said, isn’t the ARM machine 32-bit little endian? Other than possible alignment issues, it has the same coverage as i386. What lld needs is big endian build machines. </div><div><br></div><div>-Nick</div><div><br></div></body></html>
