For example, writing full words to all registers (some value) reading back the value, correcting for RAZ/WI semantics, and testing that byte accesses to those registers where that's allowed also works. If adding that on top of this series sounds like a good idea, someone should add it to the bottom of their (presumably already long) todo list, myself included.
