| I just downloaded the Opensource Asm Pro sourcecode. I would like to add support for the new instructions and adressing modes in the 68050 CPU. 1. The program counter (PC) register can be used for writes.
2. Adress registers can be used as dataregisters. etc. In asmpro I plan to add a 68050 option wich will enable the new upcodes. If you think this is needed I would like to join the Natami team. contact me at amigaguru (...) gmail.com

seems like only CALLM and RETM are unimplemented. Are such instructions used anywhere in amiga software?

| This instruction list is a bit outdated. We should nag Jens or Gunnar for a more recent one. :)

| They didn't overwrite the old one with the new one? Isn't that the version that Phil fixed up at least?

I'm using them to detect the presence of a '020 :p.Only 68020 has them, so trapping as illegal opcode is fine (but nothing else). Team Chaos Leader wrote:

Even the fixed version is somehow outdated. Everything in that area is still in discussion and (nearly) nothing can be taken as granted.

Found a little typo error into the document:
64 bit DIVU and DIVS are wrong marked: 64*32 instead of 64/32 Cheers ;-)

| AsmOne source code has also been released by the author of AsmPro IIRC its one of the first version so it's pure 68000.

| @S P: I wish you the best of luck! The Amiga needs a good and updated assembler and Asm-Pro is a good choice (however it has a few 020+ bugs that perhaps can be fixed aswell).

No. And they wouldn't be useful anyhow except for specialized operating system support. I guess Motorola also noticed. Greetings,

| Ok PPL. I have started...

I will implement support in the assembler and the disassembler. So we can compile Natami compatible EXE files. Before the Hardware is done..
:D

| Still working :D
The dissassembled code is a mess so progress is slow....
New feature today:
- Enabled byte adress register access (except adda, suba, cmpa )
move.b #1,a0
move.b d0,a0
move.b a1,a0
move.b (a1),a0
move.b (a0,d0.w),a0
move.b (pc,d0.w),a0
move.b 22(pc,d0.w),a0
etc..
The compiler generates the correct upcodes, but they are dissassembled as dc.w xxxx.
Tonight I will add support in the Disassembler.btw: I am also fixing bugs. If you want to report a bug just scream :D
In asmpro 1.17 this is not a valid instruction: tst 22(pc,d0.w)
but now it is :D

| Working hard here now. (Easter Special)
- N050: Added Full <EA> support for tst,clr,not,neg and negx (ex. neg 10(pc,d0.w*2)) (Assembler,dissassembler,debugger)
- N050: Added (B,W,L) ORIA , EORIA, ANDIA, ADDIA,SUBIA,CMPIA (Assembler,dissassembler,debugger)
These upcodes are left('?' = I don't know what the instructions are supposed to do):
FF1?
FF1A?
BKPT?
ByteRevA?
ByteRev?
BitRev?
mov3Q?
DBCC.L
BRA.B2
bsr.B2
bcc.b2
mvs.b
mvs.w
mvz.b
mvz.w
I will contiue with The special branches now. (Odd adress branch=extra bit. Dbra.l
Gunnar what is the bcc.b2 ? Goto +-256 ? instead of +-128 ?Screenshot: EXTERNAL LINK
