----------------
I think we need to do more to make sure this list of fields is kept up to date as more of these values are added or changed.

Possible idea: could we have a test that builds with `-E -dM` in both host and device mode, greps for the `__*_TYPE__`, `__*_MAX__` (etc) predefines, and compares them across the two runs?
