| The ColdFire instruction descriptions and encodings are in the ColdFire PRM... EXTERNAL LINK
Of course the N68k will support full EA where possible.

| A must have feature for an assembler is IMHO ability to optimize forward branches. I ended up using phx-ass mainly because of that. If you don't know what to add...

| This is very impressive indeed!
Any public betas of your AsmPro available yet? You should have a website for this project. It's great someone is actually working on updating an assembler for the Amiga again!I know I had some issues with AsmPro back in the days and had to turn back to AsmOne again. I recall there were issues with some 020+ codes that didn't assemble correctly. I'll try to check them out and report it to you if you can fix them? By the way, why is this guy not in the Natami-team yet? :)

| Todays work:
- N050: Added DbCC.L (Assembler,dissassembler,debugger)
(Committed to Natami cvs with binaries.)
First I will fix all the new N050 upcodes, then I will contiue with bugfixes. I am starting to understand the disassembled code now.
(Easy for an old cracker %) )
Phil:
ASM-Pro changes bra.b to bra.w if the branch owerflows. But it never changes it back. This is a bug I will remove..
I also want to add a callstack window in the debugger... But this will have to wait..Picture of the disassembler: EXTERNAL LINK

| This is one problem I have with Asm-Pro. This code compiles in Asm-One. It's obviously 020+. "Address reg. or PC expected"
jsr ([Jumptable,d2*4])

I would like to see A/NES with full 68050 support ;)
Kom igen nu Morgan. Vill spela nes när min Natami kommer.

| Great work S P.
Makes me want to start learning ASM on the amiga :D

| Sounds good.
Imageshack-images are blocked where I'm at right now so I can't see them sadly.
Is there a compiled version I can download anywhere?

I feel the same way! Just brought back TONS of old AMIGA magazines with assembler courses from home:) Cheers

| I just revieved the ASM-Pro mailing list After 5 years of inactivity.
I found out that I am not the only one who is fixing bugs. Hopefully I can merge his changes. And release a fresh ASM-PRO 1.18 soon.

If you send me an email to amigaguru (...) gmail I can send you the source with binaries We need to test it some more before we release it public.

| Found another bug I think. It compiles in AsmOne aswell. Enjoy this piece of code from A/NES PRO. :-) "out of range 8-bit"

| First of all: thanks for improving the assembler!
Please allow me to make a suggestion. I don't know whether the following has been included yet, but how about replacing 'jmp/jsr abs.l' with 'bra.w/bsr.w' where possible (as an option)? I've seen a lot of code using unnecessary jmp/jsr instructions. Or maybe instead of a replacement just a 'warning' to the user?

| I am currently working with automatic branch optimalization. And Converting jmp's to bra.w/bra.b where possible is a good idea.
The N050 has an extra bit in the adress so every branch can jmp 2 times longer than the previous Mc68k's.bra.b +- 256bytes
bra.w +- 65535 bytes
bra.l Full 32bit adress space Recompiling sourcecode with the N050 setting and the brachoptimizer will generate more compact code.

This is why I like PhxAss. You no longer have to care about these anymore...@ S P :
If you don't want what optimization options to add, well, try PhxAss (or VAsm) and compare code size. You produce bigger code ? Then compare the executables, and see what you have to do.

AsmPro have a Assemble and optimize (Command AO) that will optimize some of the branches. But it doesn't optimize them all, and I think there are errors in the size calculations. I tried to fix it, but it became a mess, and I had to rollback. I got your email, and will try to do some more fixes soon.
