Yes!!!  That should have always been that way.

Yep.

Don't stop there.  It should be possible to trim it down to something like:
	- register_type
	- num_regs
	- num_pseudo_regs
	- register_name
(looking at the d10v I've a few more to eliminate).

This means that a huge chunk of nastiness can finally be expunged from 
GDB.  Ya!
