If you’re having byte order issues on arm you will have them on x86 as they are both little endian, and modern arm (last ~10 years) handles unaligned access. You’ll also find there is a lot of code designed for use on battery powered Arm CPUs, they are used in almost all mobile phones, meaning many popular JITs have been ported.
