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. */
