// THE OPCODE TABLE ITSELF
//
// The opcode table "opTable" describes each opcode and function.
// There is an entry for each opcode, and for each function.
//
// The table is organized as follows:
//                invalid-ops,
//                non-terminal-ops,
//                terminal-ops,
//                functions,
//
//    This organization is NOT required:
//           no assumptions are made on it.
//
//    Searches based on opcode must search
//             INVALID, TERMINAL and NON_TERMINAL
//
//    Searches based on instruction name must search
//             TERMINAL and FUNCTION
//
//

/*** opTableInit - initialize fields used in and with the opTable
*
*   Purpose:
*       This routine is called once, and sets up pointers to the
*       subtables embedded in the opTable, such as AddOpTab, and
*       sizes for these subtables.  It also checks that all like
*       instructions are grouped together in the table, which is
*       the only requirement on it.
*
*   Input:
*       None.
*
*   Output:
*       None.
*
*   Errors:
*       If the table is not properly organized (four types separated,
*       and the functions for a single opcode grouped), this prints a
*       messages and fails
*
*   Exceptions:
*       None.
