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 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;

INSTRUCTIONS

|
/* Since the 68000 , the 68010 and the 68020 instruction sets are rather
|
|
* extensive, especially because e.g. 'add.l' and 'add.w' are
|
|
* considered different instructions, only those instructions are
|
|
* listed here that are used in the rest of this table.
|
|
*
|
|
* Instruction timing cost cannot be accurately given, nor the timing
|
|
* cost for getting operands. Detailed information about this can be
|
|
* found in the "MC68020 User's Manual", section 9, about instruction
|
|
* timing. The cost used in this table are 'worst case' cost, as
|
|
* mentioned in section 9 of the user's manual. Furthermore, the
|
|
* timing information for the 68k[24] and the 68020 differ, which
|
|
* means that the 68k[24] will not always have the best code
|
|
* possible.
|
|
*
|
|
* The first few instructions had to be added because register
|
|
* variables are used. The LOCALs below are register variables.
|
|
* One may not conclude that these operations are also allowed
|
|
* on LOCALs that are not register variables.
|
|
* The cost have been adapted, but are not accurate; when 'real'
|
|
* LOCALs are used the cost are very inaccurate.
