Does anyone know of a format for declaring binary data formats, which can then be compiled into reader/writer code for various languages? I'm not looking for something like protocol buffers—this is explicitly for reverse engineering, so it would have to be something that can flexibly accommodate existing semi-arbitrary binary data.

in reply to @nex3's post:
This question has made me realize how many binary data formats I’ve seen defined/described with just a literal C struct definition.
Given that C struct fields can be freely reordered and padded by the compiler and they contain no information about endianness, that doesn't sound like a very good convention.
it is not the case they can be reordered but yes the padding is up to the whims of the compiler
Oh, it isn’t. But that doesn’t mean people don’t do it. (And if it’s understood as a sort of pseudocode, with 1-byte alignment, 4-byte ints, a defined endianness, etc., then it does work fairly well for documentation purposes)
This might be completely off the mark, but would QuickBMS be relevant? http://aluigi.altervista.org/quickbms.htm
