  27    includes almost all of the extended instruction mnemonics.  This
  28    permits the disassembler to use them, and simplifies the assembler
  29    logic, at the cost of increasing the table size.  The table is
  30    strictly constant data, so the compiler should be able to put it in
  31    the .text section.

 148 /* The new format of the INSTR_x_y and MASK_x_y defines is based
 149    on the following rules:
 150    1) the middle part of the definition (x in INSTR_x_y) is the official
 151       names of the instruction format that you can find in the principals
 152       of operation.
 153    2) the last part of the definition (y in INSTR_x_y) gives you an idea
 154       which operands the binary represenation of the instruction has.
 155       The meanings of the letters in y are:
 156       a - access register
 157       c - control register
 158       d - displacement, 12 bit
 159       f - floating pointer register
 160       i - signed integer, 4, 8, 16 or 32 bit
 161       l - length, 4 or 8 bit
 162       p - pc relative
 163       r - general purpose register
 164       u - unsigned integer, 4, 8, 16 or 32 bit
 165       m - mode field, 4 bit
 166       0 - operand skipped.
 167       The order of the letters reflects the layout of the format in
 168       storage and not the order of the paramaters of the instructions.
 169       The use of the letters is not a 100% match with the PoP but it is
 170       quite close.
 171
 172       For example the instruction "mvo" is defined in the PoP as follows:
 173
 174       MVO  D1(L1,B1),D2(L2,B2)   [SS]
 175
 176       --------------------------------------
 177       | 'F1' | L1 | L2 | B1 | D1 | B2 | D2 |
 178       --------------------------------------
 179        0      8    12   16   20   32   36
 180
 181       The instruction format is: INSTR_SS_LLRDRD / MASK_SS_LLRDRD.  */
