I don't see a common place for the register names, the current design assumes they're a private static detail of a target - suggestions welcome though, I agree the duplication is pretty terrible. As for the features, if you're thinking about extending and then re-using `AMDGPU::fillAMDGPUFeatureMap`, I can do that, and it's probably a better solution I had not considered. Is that what you had in mind?
