 * Thanks to ...
 *
 * Neil Bradley	 (lots of optimisation help & ideas)
 *
 *---------------------------------------------------------------
 * History (so we know what bugs have been fixed)
 *
 * 02.11.98 MJC	- CMPM bug, overwriting first value
 * 04.11.98 MJC	- Debug timing - same as C core
 *						save PC on calls to C memory routines
 * 05.11.98 NS	 - Re-insert changes to make work on OS/2
 * 06.11.98 MJC	- Flags saved on ADDA commands
 *						X set on ADD commands
 * 23.11.98 MJC	- Alternate Memory Read/Write for non DOS ports
 * 24.11.98 CK	 - Add WIN32 specific stuff
 * 25.11.98 DEO	- ABCD Size not initialised
 * 21.12.98 MJC	- Change register saving on Memory Banking
 * 13.01.99 M/D	- Change to new C core disassembler
 * 19.01.99 MJC	- Proper? support for new Interrupt System
 * 17.02.99 MJC	- TRACE68K define added
 *                ABCD,SBCD not keeping Z flag
 *                JMP, JSR for some EA combo's damaging flags
 *                DIVU - Overflow not being set correctly
 *                ASL/ASR - Flag Handling now correct
 *                some minor optimisations
 * 13.03.99 DEO	- Added new cycle timing
 * 24.03.99 MJC	- TRACE68K define removed
 *                NEW INTERRUPT SYSTEM only
 *                interrupt check sped up (when not taken)
 *                STOP checks for interrupt
 * 01.04.99 MJC	- OS2 specifics added
 *                MOVEM reference point moved
 *                Data and Address register mode combined for :-
 *					 	movecodes
 *                dumpx
 * 04.05.99 MJC	- Add Previous PC support to MOVE.B #X,XXXXXX.L (F1 Dream)
 *                ABCD/SBCD could corrupt zero flag
 *                DIVS/DIVU overflow should not update register

 *                Some optional bits now selected by DEFINES
 * 27.05.99 MJC	- Interrupt system changed
 * 28.05.99 MJC	- Use DEFINES in more places
 *                Interrupt check running one opcode when taken
 * 16.07.99 MJC	- Reset - Preload next opcode / external call
 *                68010 commands almost complete
 *                more compression on jump table (16k smaller)
 *                Some optimising
 *					 	  shl reg,1 -> add reg,reg
 *                  or ecx,ecx:jz -> jecxz
 * 22.08.99 DEO	- SBCD/ABCD sets N flag same as carry
 * 19.10.99 MJC	- Change DOS memory routines
 *                Change DOS Clobber flags (ESI no longer safe)
 *                Save EAX around memory write where needed
 *                bit commands optimised
 * 25.10.99  MJC  - Was keeping masked register on read/write
 *                if register was preserved over call
 *                ESI assumed 'safe' again
 * 25.10.99  MJC  - Bank ID moved to CPU context
 * 03.11.99 KENJO - VC++6.0 seems not to preserve EDI. Fixed "ABCD -(A0), -(A0)" crash / "roxr (A0)"-type shift crash
 * 13.11.99 KENJO - Fixed "NABC"
 *                Now Win32 uses FASTCALL type call for interrupt callback
 * 09.02.00  MJC  - Check CPU type before allowing 68010/68020 instructions
 *                remove routines for 5 non existant opcodes
 * 05.03.00  MJC  - not command decrement A7 by 1 for bytes
 * 10.03.00  MJC  - as did btst,cmpm and nbcd
 * 22.03.00  MJC  - Divide by zero should not decrement PC by 2 before push
 *                Move memory banking into exception routine
 * 14.04.00 Dave  - BTST missing Opcode
 *                ASL.L > 31 shift
 * 20.04.00  MJC  - TST.B Also missing A7 specific routine
 *                - Extra Define A7ROUTINE to switch between having seperate
 *                routines for +-(A7) address modes.
 * 24.06.00  MJC  - ADDX/SUBX +-(A7) routines added.
 *                TAS should not touch X flag
 *                LSL/LSR EA not clearing V flag
 *                CHK not all opcodes in jump table
 *                Add define to mask status register

 *                Fix flag handling on NEGX
 *                Really fix ADDX/SUBX +-(A7)
 *                PC could be set wrong after CHK.W instruction

 *                ABCD/SBCD missing +-(A7) Routine
 *                TAS missing +-(A7) Routine
 *                Bitwise Static missing +-(A7) Routine
 *                CMPM missing +-(A7) Routine
 * 30.09.00 DEO	- added mull, divl, bfextu
 *                added '020 addressing modes
 *                fixed $6xff branching
 * 23.01.01 MJC	- Spits out seperate code for 68000 & 68020
 *                allows seperate optimising!
 * 17.02.01 MJC	- Support for encrypted PC relative fetch calls
 * 11.03.01 GUTI  - change some cmp reg,0 and or reg,reg with test
 * 13.03.01 MJC	- Single Icount for Asm & C cores
 * 16.05.01 ASG	- use push/pop around mem calls instead of store to safe_REG
 *                optimized a bit the 020 extension word decoder
 *                removed lots of unnecessary code in branches
 *---------------------------------------------------------------
 * Known Problems / Bugs
 *
 * 68000
 * None - Let us know if you find any!
 *
 * 68010
 * Instructions that are supervisor only as per 68000 spec.
 * move address space not implemented.
 *
 * 68020
 * only long Bcc instruction implemented.
 *---------------------------------------------------------------
 * Notes
 *
 * STALLCHECK should be defined for Pentium Class
 *							 undefined for P2/Celerons
 *
 * ALIGNMENT is normally 4, but seems faster on my P2 as 0 !
 *
 *---------------------------------------------------------------
 *
 * Future Changes
 *
 * 68020 instructions to be completed
 * assembler memory routines												+
 *
 * and anything else that takes our fancy!
