x86

I would like to learn the x86 Instruction Set Architecture. I don't meaning learning an assembly for x86. I want to understand the machine code baby.

The reason is that I would like to write an assembler for x86. Then I want to write a compiler that compiles to that assembly.

I know that there are the Intel manuals and AMD manuals that cover the x86 instruction set. But those are very large and dense.

I'm wondering if there is a more approachable (possibly tutorial) approach to learning the x86 instruction set architecture.

Title says it all. The error NASM gives (dispite my working OS) is "invalid effective address". Now i've seen many examples of how to use LEA and i think i gots it right but yet my NASM dislikes it. I tried "lea cx, [cx+9]" and it worked; "lea cx, [bx+cx]" didn't. Now if i extended my registers… >>> More
