TOKENS

	/* Not all addressing modes available on the MC68020 are used in this
	 * table. E.g (Dn), data register indirect is not used. Compared to
	 * (An), address register indirect, (Dn) requires two more bytes and
	 * several more clock cycles. Using (Dn) is even more expensive in
	 * time than first moving Dn to an address register An, and then using
	 * (An). For this kind of reasons several addressing modes are
	 * not used in this table.
	 *
	 * Cost in bytes may sometimes be incorrect. Several effective addresses
	 * use displacements that can occupy either 2 or 4 bytes. These are not
	 * considered different TOKENS in this table.
	 *
	 * Data registers are the only registers used as index registers in this
	 * table; address registers are only used to hold addresses.
	 *
	 * For the m68k4 table: the MC68000 and MC68010 have two modes that use
	 * displacements (offsets) of limited size:
	 * 	- offset(A_REG, Index_reg), where offset is only 8 bits, and
	 *	- offset(A_REG), where offset can only be 16 bits.
	 * To make sure that no output is given with offsets too large, two
	 * extra tokens are declared: t_regAregXcon and t_regAcon. These are
	 * used as addresses to these modes. Whenever the displacements become
	 * too large, they are transformed into different tokens.
	 *
	 * Sometimes some TOKENS are used with displacements (offsets) of 0.
	 * It would have been possible to provide separate TOKENS for these, in
	 * case the assembler doesn't handle zero offsets optimally. This
	 * however would mean a very large amount of extra TOKENS and SETS for
	 * a very small profit in code bytes, so we won't do that.
	 *
	 * To prevent the TOKENS list from getting too unreadable, #ifdefs are
	 * used to form three parts: 
	 *	(i)   the common part;
	 *	(ii)  the m68k4 part;
	 *	(iii) the m68020 part;
