/* A note about the fields array in the opcodes structure:
   The operands are listed in the order they appear in the output.

   This table is arranged in numeric order of the opcode.  Note that some
   opcodes have defined bits in odd places so not all forms of a command
   will be in the same place.  This is done so that a binary search can be
   done to find the opcodes.  Note that table D.2 in the MPC860 User's
   Manual "Instructions Sorted by Opcode" does not account for these
   bit locations */
