At the moment I am trying to finish the arch manual, make or1ksim to be
compliant with the architecture and make binutils and or1ksim compatible -
so that we have an environment with all the bug fixed. Also something needs
to be done with orX.h files. They are now used by binutils, or1ksim and
gen_or1k_isa. So Jimmy use the _form_ of or16.h that I sent you. Create you
_mnemonics_ similar to or32.h mnemonics (I recommend we loose 32, 16, 8
numbers in mnemonics and replace that with letters like in or32.h).
Regarding the instruction you want to have just select yourself. If I will
not agree with your selection I will tell you. At the moment I am more busy
with the SPRs.

Johan, regarding relocations. I suggest we try to add relocations that are
handled in a uniform way. Similar to letters that describe insn operands
(stuff that I started to add in these days - see
binutils/include/opcode/or16.h in CVS).

Damjan
