Based on the pains I'm experiencing with going through trying to get 
some MMX changes for x86 in a state where I can submit them, I suspect 
it is the better of the alternatives.

The x86 has a mix and that is just confusing.  I don't know what can 
change and what can't change and what secret relationships there are 
between the constants and variables.

On paper, it should be possible to describe the entire raw regcache 
using constants.  I'm finding that, in reality, until all the relevant 
framework is fleshed out (eg my regcache breakage, everything 
multi-arch) it isn't really possible.  Sigh.

enjoy,
Andrew
