/* The new format of the INSTR_x_y and MASK_x_y defines is based
   on the following rules:
   1) the middle part of the definition (x in INSTR_x_y) is the official
      names of the instruction format that you can find in the principals
      of operation.
   2) the last part of the definition (y in INSTR_x_y) gives you an idea
      which operands the binary represenation of the instruction has.
      The meanings of the letters in y are:
      a - access register
      c - control register
      d - displacement, 12 bit
      f - floating pointer register
      i - signed integer, 4, 8, 16 or 32 bit
      l - length, 4 or 8 bit
      p - pc relative
      r - general purpose register
      u - unsigned integer, 4, 8, 16 or 32 bit
      m - mode field, 4 bit
      0 - operand skipped.
      The order of the letters reflects the layout of the format in
      storage and not the order of the paramaters of the instructions.
      The use of the letters is not a 100% match with the PoP but it is
      quite close.

      For example the instruction "mvo" is defined in the PoP as follows:

      MVO  D1(L1,B1),D2(L2,B2)   [SS]

      --------------------------------------
      | 'F1' | L1 | L2 | B1 | D1 | B2 | D2 |
      --------------------------------------
       0      8    12   16   20   32   36

      The instruction format is: INSTR_SS_LLRDRD / MASK_SS_LLRDRD.  */
