  1. The most basic x86 arithmetic instructions operate on two 32-bit registers. The first operand acts as a source, and the second operand acts as both a source and destination. For example: addl %ecx, %eax – in C notation, this means: eax = eax + ecx;, where eax and ecx have the type uint32_t.

    How to learn x86 assembly?

    x86 can be tedious to learn for any number of reasons:

    • no two registers are the same.
    • not all instructions work with all registers.
    • Some branch instructions have a very short range, so you may see branch to branch instructions
    • The number of different address modes can be surprising.

    • This document contains very brief examples of assembly languageprograms for the x86. The topic of x86 assembly language programming ismessy because: 1. There are many different assemblers out there: MASM, NASM, gas,as86, TASM, a86, Terse, etc. All use radically different assemblylanguages. 2. There are differences i…
    • Regardless of the assembler, object file format, linker oroperating system you use, the programming process is always the same: Each assembly language file is assembled into an "object file"and the object files are linked with other object files to forman executable. A "static li…

    The <main> code looks more or less the same as the previous example, so let’s focus our attention on the <variable> function. As we can see in the movl $0x6,-0x4(%rbp) command, the number 0x6 is pushed onto the stack 4 bytes lower than the base stack address stored in the register -0x4(%rbp).This result agrees with our understanding that local variables are stored on …
