/*
* 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.
*
* The source for the insn timings is Markt & Technik's Amiga Magazin 8/1992.
