I have had problems on other sites where the captcha thing was unreadable or just plain wrong. But somehow I hacked my way into the AmigaCoding.de site. I might have just gotten lucky.

I am like u, I have to give up on sites that are overly hard to sign up to.

Also the site has a bug where it sometimes use a random number for the text instead of a real number. This then produces crystal clear black text on a crystal clear black background which, surprisingly, is impossible to read.
For example, all the buttons that say "Submit" or "Preview" are 100% unreadable.

Lots of websites have the same bug.

But I don't think that bug has afflicted you in ur case.

Maybe he could sign u up "manually" himself then transfer control of the account over to u?

One more question regarding a website for assembler coding on old Amigas:

As I don't want to make a blog, would it be best to start forumthreads on both Amigaworld and EAB to be able to talk about the code, if there is something to talk about?

@ChaosLord

I see the Problems with Spam on all sites (at the moment on morphzone.org) and got a lot of warnings regarding this when I created the site. I have just new registered in a couple of minutes so it is possible.

Disassemblers can do a pretty good job of determining what is a string. Small data can be difficult to judge whether it's code or data (strings) though. Here is a newer version of ADis that I have been working on:

I tried it, it did not disassemble every thing, it did a better job at finding text strings.

Quote:

It doesn't tell you the names of Amiga hardware registers like IRA does though.

But it does tell you original hex values so you can revert back to hex if the compiler did something wrong.

None of disassemblers renames the labels to some thing readable if its strings, this should be possible.

I wonder how close in speed a PPC optimized JIT/dynrec compiler converting optimized 68k code could come to the average compiled PPC code.

I think thats hard question to answer, it will depend on the code, cache misses, and amount of emulation and optimizing that goes in to the generated code, and number of native system calls.

Dynrec is not just for emulators it can be used to optimize code, by replacing old machine code whit whit faster new machine code that do more in fewer clock cycles, like in the example I liked to.

By for example converting MC68000 to MC68020 code.

I bet there wouldn't be too big of difference.

The result might where a lot, generally you get speed up, the difference between script langrages that uses JIT and the onces that does not, is really big.

http://luajit.org/performance_ppc.html

On LuaJIT 2.0.0 interpeted vs JIT, JIT is 26.71 times faster in the md5 test, but the binaray-trees is only 1.22 times faster.

If you know of any Mandel broth test for 680x0 I be happy to test it whit Petunia JIT enabled, disabled and in UAE whit out JIT, and native PPC if it can be recompiled.

You do have to choose the correct processor (like ADis -m6 for 68060+MMU+FPU) as only 68000 instructions will be identified by default. Dead code and unidentified code will not be disassembled currently because of the way ADis follows the execution route of the code. You can tell ADis to disassemble that offset as code with a command line option though. Eventually there could be an option for another pass to try and disassemble what is left or mark it as possible dead code for removal. ADis needs to get a little smarter at identifying code, data and text first. It's not bad but could be better.

You can specify ADis -a like IRA for helpful comments. There is more info than IRA with the most given with ADis -a8. This will show flags of how the data was identified, like text or relocatable. All the text is in a list+hash table (see refs.c) and it's possible to change the name of a reference. If you use ADis -l, some library information is defined kind of like what you are asking for. ADis can read symbols and use .fd files to name functions. Options to name strings like "intuition.library",0 to IntuitionName and renaming absolute values to register names shouldn't be too difficult.

There is also the Amiga disassembler Resource which has an editor so much more can be done. It's not free and the editor might have problems on AmigaOS 4 though.

True. It depends on how well the dynrec is coded though. In the case of the DosBox Dynrec it's a de-optimizer .

I have been working on the layout of the website now, and it all seems to be nice and good, so the site will be up and running with the first code example sometime during the weekend.

As i have been making the website, I haven't had any time to make Amiga code, but I will put up a version of my first test done some days ago.

I will tell the domain of the site when it really is up and running.
