The x86 Assembly Language Reference Manual documents the Oracle Solaris x86 assembler, as(1). This manual is provided to help experienced assembly language programmers understand disassembled output of Solaris compilers. This manual is neither an introductory book about assembly language programming nor a reference manual for the x86 architecture.

The geek suite is intended for deeper research of x86 architectures' instruction set. This includes geek32, geek64, and geek editions (by opcode) and geek32-abc, geek64-abc, and geek-abc editions (by mnemonic). More on the purpose and use of this suite see close below. Don't get confused by geek(-abc) and coder(-abc) editions. ...

Online x86 / x64 Assembler and Disassembler. This tool takes x86 or x64 assembly instructions and converts them to their binary representation (machine code). It can also go the other way, taking a hexadecimal string of machine code and transforming it into a human-readable representation of the instructions.

The topic of x86 assembly language programming is messy because: There are many different assemblers out there: MASM, NASM, gas, as86, TASM, a86, Terse, etc. All use radically different assembly languages. There are differences in the way you have to code for Linux, OS/X, Windows, etc. Many different object file formats exist: ELF, COFF, Win32 ...

05/12/2012 · To find out what an assembly instruction does, I recommend using Google. In Google you can just write the name of the instruction, in this case test, and something like intel instruction (for Intel instructions): Google: test intel instruction. ... mov instruction in x86 assembly. 2233.

The x86 processors have a large set of flags that represent the state of the processor, and the conditional jump instructions can key off of them in combination. CF - carry flag Set on high-order bit carry or borrow; cleared otherwise PF - parity flag Set if low-order eight bits of result contain an even number of "1" bits; cleared otherwise
