The current plugin API is very incomplete. Most actual plugins must simply call functions available in the backend, although these functions are not officially exported. This means that such plugins must be rebuilt for each new version of GCC. There are various ideas for how to fix this situation; it's not yet clear exactly what will happen. Ian
