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. */
