Title: xchg rax,rax ; 0x40 assembly riddles
Post by: xorpd on December 09, 2014, 11:40:24 PM
EDIT: Added usage instructions
Hi,
I made a collection of interesting bit tricks and techniques that I found over the last years. I put them into 0x40 assembly riddles, each one should teach you about one thing.
It could be found here: http://xchg.xorpd.net
Moving to the next code snippet is done by clicking on "inc". (Or "dec" for the previous one).

You could also get the hard copy for those snippets, though all of them are on the website.

I hope that you find it useful. Have fun :)
xorpd.

Click on the "inc" and "dec" on the top.
I should have added more information about how to use it... sorry.

No, every time. Is that the content of your book? Some assembly language instructions without comments?  :eusa_boohoo:

No, arranging almost meaningless sequences of assembler instructions against a black background is a form of art. You may call it nerd poetry

Fine. Again closed a gap in knowledge.
