I'd like to announce new release of my instruction reference. Both x86 and x64 editions are available.

For coders, it should serve as quick, rich instruction reference. Reversers can use it for deep research of x86 architectures' instruction set (thanks to its exactness).

http://ref.x86asm.net

You can start quickly with "coder32's" edition:

http://ref.x86asm.net/coder32.html

Note that the reference is still not complete (x87, MMX, SSEs are missing), but all general and system instructions are already included so it is already useful. Although the reference has been reviewed by two people many times, it can still contain small bugs so your review and comments are appreciated.

I prefer dedicated discussion forum. You don't need to register in order to reply:

Nice!!! How many pages is the printed version? You could mention that on your webpage

Edit: 8 pages!!!

It depends on the scale you choose. My copy of geek's edition is 48 rows per page (landscape). It contains 16 pages.

I'm gonna mention it.

It almost fits portrait here on 8 pages. Just the description gets slightly clipped at the end. So I guess... adjust the margins?

Edit: You can also say compiler-builders can use it to implement their own quick assembler because all the opcode hex are there! .

I found it unreadable when it fits portrait (even with slipped description). Even the landscape is quite small, and I'm not shortsighted

Portrait would be more usable though...

Oh ok I used to sometimes print stuff at pt 5 Yes its just readable...

Thanks MazeGen, it's going to help me a lot

Personally, I'm not for sure if I like it or not...
I think it would be really handy for looking up unimplemented opcodes in my emulator, but I don't see much use in it for general programming...

I do wish there was a way to sort it though...like into opcode "groups" like all add opcodes, all mov opcodes...ect

hckr83, I know - for now, it is handy mainly for reversers and machine code maniacs. You can very quickly look up particular opcode and gather almost all of its important atributes.

For future, I plan many various editions, including a suite of editions with alphabetically sorted mnemonics.

However, my time for this project is limited so it'll take some time. It would be nice to get someone who is interested in asm and knows XSLT processing as well and can help me. Unfortunately, asmers are usually not interested in XML and this sort of things...

During the past couple of weeks, I have noticed, quite frequently, that the web site is non-functioning, as is the case, right this minute, as I write this:
http://board.x86asm.net/index.php

Thanks for the report, Tom. That's weird, it always works for me. You mean that the site is completely down, or too slow, or just the board doesn't work as expected?

I should reactivate "failure-monitoring" of the site to make sure it works well.

Well, perhaps you can ask someone else to check it, to confirm that it is not some kind of local issue on my computer, or with North America. The message is the standard one: Web Page is currently unavailable..... As I write this, I have the same error message, still!!!

Works here. Perhaps you have a transparent/opaque HTTP proxy?

Tom, it works for HyperVista as well (thanks for testing), so it looks like some local issue of yours...

Yup, works perfectly for me this morning!!! So, I conclude it is some kind of intermittent problem only on my computer....Thanks for the help.

That is amazing MazeGen, its so clean, tidy, and all packed up nicely. I will deffinetly print off a copy for reference, would be nice to have the extra instruction set too

thanks

At request, I have released PDF edition for each HTML edition to make the printing easy. Unfortunately, some editions contain one page without borders

Very nice indeed!

I am just learning and flipping through intel's manuals is not much fun.

This makes my life a whole lot easier.

Now if i can just put any of this to good use?

Thanks, and happy coding!

This version adds all x87 FPU opcodes (D8-DF).

I have also set up a store:

omg soo much, i thought x86 is 40-50 instructions max. Well ill start learning
