Raw Normal View History

- Added the Musashi 68K emulator by Karl Stenerud. Obtained Karl's explicit permission to relicense the code under GPL. - Added a 68K interface, CPU/68K/M68K.*. - Moved Turbo68K source files to CPU/68K/Turbo68K. It is no longer used but is being retained in the source tree for now. The LSR instruction has not been fixed in this update. - Changed sound board code to use the new 68K interface (and hence, Musashi). - Changed version string from 0.2-WIP to 0.2a-WIP. This is still an alpha version. - Above changes have broken the 68K debugger.

/* Input file for m68kmake
* -----------------------
*
* All sections begin with 80 X's in a row followed by an end-of-line
* sequence.
* After this, m68kmake will expect to find one of the following section
* identifiers:
* M68KMAKE_PROTOTYPE_HEADER - header for opcode handler prototypes
* M68KMAKE_PROTOTYPE_FOOTER - footer for opcode handler prototypes
* M68KMAKE_TABLE_HEADER - header for opcode handler jumptable
* M68KMAKE_TABLE_FOOTER - footer for opcode handler jumptable
* M68KMAKE_TABLE_BODY - the table itself
* M68KMAKE_OPCODE_HANDLER_HEADER - header for opcode handler implementation
* M68KMAKE_OPCODE_HANDLER_FOOTER - footer for opcode handler implementation
* M68KMAKE_OPCODE_HANDLER_BODY - body section for opcode handler implementation
*
* NOTE: M68KMAKE_OPCODE_HANDLER_BODY must be last in the file and
* M68KMAKE_TABLE_BODY must be second last in the file.
*
* The M68KMAKE_OPHANDLER_BODY section contains the opcode handler
* primitives themselves. Each opcode handler begins with:
* M68KMAKE_OP(A, B, C, D)
*
* where A is the opcode handler name, B is the size of the operation,
* C denotes any special processing mode, and D denotes a specific
* addressing mode.
* For C and D where nothing is specified, use "."
*
* Example:
* M68KMAKE_OP(abcd, 8, rr, .) abcd, size 8, register to register, default EA
* M68KMAKE_OP(abcd, 8, mm, ax7) abcd, size 8, memory to memory, register X is A7
* M68KMAKE_OP(tst, 16, ., pcix) tst, size 16, PCIX addressing
*
* All opcode handler primitives end with a closing curly brace "}" at column 1
*
* NOTE: Do not place a M68KMAKE_OP() directive inside the opcode handler,
* and do not put a closing curly brace at column 1 unless it is
* marking the end of the handler!
*
* Inside the handler, m68kmake will recognize M68KMAKE_GET_OPER_xx_xx,
* M68KMAKE_GET_EA_xx_xx, and M68KMAKE_CC directives, and create multiple
* opcode handlers to handle variations in the opcode handler.
* Note: M68KMAKE_CC will only be interpreted in condition code opcodes.
* As well, M68KMAKE_GET_EA_xx_xx and M68KMAKE_GET_OPER_xx_xx will only
* be interpreted on instructions where the corresponding table entry
* specifies multiple effective addressing modes.
* Example:
* clr 32 . . 0100001010...... A+-DXWL... U U U 12 6 4
*
* This table entry says that the clr.l opcde has 7 variations (A+-DXWL).
* It is run in user or supervisor mode for all CPUs, and uses 12 cycles for
* 68000, 6 cycles for 68010, and 4 cycles for 68020.
