Not really. The only ones I ever would have found useful would be movement
to/from the shadow regs. Hmmm, actually we may have had an assembler macro
to create mtcpu/mfcpu instructions using .word directives. It's hard to
remember since I haven't done PA OS work in a while.

My understanding was that these were pretty critical instructions for an
OS implementation. Doesn't one of the other open-source OSes have a need
for these as well?

I recall using a similar trick initially with the RTEMS PA port and then
we decided it was ugly and error prone. It was easier to simply add the
instructions to gas. :)

Jeff, can I leave this bit to you?

I do not know if I have submitted the individual patches in this in the
past or not. I wanted to make sure that it got in though. The patch
applied without hassle to binutils-2.9.1.0.14 so I doubt they are in.
This patch does a few minor things for RTEMS targets mostly in
configuration files. It also adds some RTEMS targets that are
either aliases or copies of existing targets with no new files.
Included in this patch is one thing I am pretty sure will be rejected.
The mod to opcode/hppa.h adds instructions and unless something has
changed recently, knowing that these instructions exist requires having
access to a manual that was restricted in some way. Perhaps one of the
HPPA folks will be able to state something more recent HPPA technical
information.
