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 m68k2 and 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 m68k2 and m68k4 part; * (iii) the m68020 part; */ /* Part (i) */ zero_const = {INT num;} WORD_SIZE cost(0,0) "#" num . small_const = {INT num;} WORD_SIZE cost(0,0) "#" num . bconst = {INT num;} WORD_SIZE cost(0,0) "#" num . const = {INT num;} WORD_SIZE cost(4,4) "#" num . #if WORD_SIZE==2 /* ???
