/*
 * UAE - The Un*x Amiga Emulator
 *
 * MC68000 emulation generator
 *
 * This is a fairly stupid program that generates a lot of case labels that
 * can be #included in a switch statement.
 * As an alternative, it can generate functions that handle specific
 * MC68000 instructions, plus a prototype header file and a function pointer
 * array to look up the function for an opcode.
 * Error checking is bad, an illegal table68k file will cause the program to
 * call abort().
 * The generated code is sometimes sub-optimal, an optimizing compiler should
 * take care of this.
