I'm still wainting for an answer to my questions here.

Do you mean to add  SIM_SH_FR1_REGNUM .. SIM_SH_FR15_REGNUM and the various
individual banked regnums?  I could do that.

OTOH, if you mean to remove the seed values like 24 for SIM_SH_DSR_REGNUM and
40 for SIM_SH_MOD_REGNUM, making a flat enum, that would break backwards
compatibility,
as we have some gaps, and overlaps between floating point and dsp registers.
(This mirrors an overlap in the instruction set.  In fact the instructions to
manipulate
 FPSCR and DSR are the same, and the simulator makes use of this by treating
them really
 as the same.)
