The code in this file is just checking we emit bswap
, can't we instead make this something like
#[cfg(target_endian = "little")]
let bswap = u16::to_be;
#[cfg(target_endian = "big")]
let bswap = u16::to_le;
let addr16 = [
bswap(value[0]),
// etc.e
];

Nice idea, done!
Instead of not generating the function at all on big endian (which makes the CHECK lines fail), instead use to_le() on big endian, so that we essentially perform a bswap for both endiannesses.
