  27 /* This file contains the opcode table for the MAXQ10/20 processor. The table
  28    has been designed on the lines of the SH processor with the following
  29    fields:
  30    (1) Instruction Name
  31    (2) Instruction arguments description
  32    (3) Description of the breakup of the opcode (1+7+8|8+8|1+4+4|1+7+1+3+4
  33        |1+3+4+1+3+4|1+3+4+8|1+1+2+4+8)
  34    (4) Architecture supported
  35
  36    The Register table is also defined. It contains the following fields
  37    (1) Register name
  38    (2) Module Number
  39    (3) Module Index
  40    (4) Opcode
  41    (5) Regtype
  42
  43    The Memory access table is defined containing the various opcodes for
  44    memory access containing the following fields
  45    (1) Memory access Operand Name
  46    (2) Memory access Operand opcode.  */
