ASM on 64 bit platform vs 8086 asm

Over some years ago, I had learned great deal of assembly, essentially the 8086 instruction set.
Part of the reason was, that I used in in my undergrad project.

Now,after like 4-5 yrs I am again trying to see the assembly code(thanks gcc for providing conversion) ,and MAN! that code I do not recognize, movl, movd, movq ,movzbl there are like a thousand variations of mov itself ...

although feels good to see at something you did long ago...

  1. ahh..was searching ASM and found your blog. :)
    Btw, I found it works well on 64 bit. Did you try any assembly coding? I did not..I want to do it on 64 bit. Any differences apart from obvious registers size difference?

  2. no i didnt program, the instruction set has changed quite a bit... concepts of segments is not there etc
