I don't get it. Why do you need to "fill out missing cmp_type values"
considering that you're never assigning the third field in this patch?
Are you planning on filling in the third field in a future patch?

Compiler diagnostic:

    warning: declaration of 'struct used_atom' will not be
        visible outside of this function [-Wvisibility]

Indeed, it seems rather odd to introduce the new field in this patch
but never actually do anything with it. It's difficult to understand
the intention.
