Someone should write a sparc disassembler. It should be rather easy.
   (Chris Hopps wrote the m68k ddb disassembler in a few days. The figure
   of 4 pizzas and numerous packages of smokes comes to mind.  The sparc
   is a lot simpler.)

keep in mind the gdb has a disassembler in it that works for
the sparc, so a lot of the code could easily be ripped off
from there.  i personally have no desire to become intimate
with sparc asm.... ;-)
