I would be scared of using it for IO... With a struct bit field, I don't know what bit offset a field ends up with, I don't know how it gets padded, and I don't know how large the generated load and store becomes. I'd rather do the bit operations and store myself.

__attribute__((packed)) is pretty much required for this use case.

  That gets rid of the padding issue, but still does little to tell me which bit corresponds to which field.
