1/* Interface between the opcode library and its callers.
2   Written by Cygnus Support, 1993.
3
4   The opcode library (libopcodes.a) provides instruction decoders for
5   a large variety of instruction sets, callable with an identical
6   interface, for making instruction-processing programs more independent
7   of the instruction set being processed.  */
