Re: [RFC] Changes to *_*regset functions

Point taken.  I think we need to be careful here though.  To me, 
supply_gregset() is more like the DWARF2_REG_TO_REGNUM() functions then 
part of an ABI.  They provide a mapping between an external and an 
internal representation. They happen to get lumped into gdbarch because 
that is all we have at present.

It is sounding like there are three components here: ISA, ABI and this 
interface code.
