Guide to Using Assembly in Visual Studio — a tutorial on building and debugging assembly code in Visual Studio Intel x86 Instruction Set Reference; Intel's Pentium Manuals (the full gory details) Registers. Modern (i.e 386 and beyond) x86 processors have eight 32-bit general purpose registers, as depicted in Figure 1. The register names are ...

Welcome to this tutorial series on ARM assembly basics. This is the preparation for the followup tutorial series on ARM exploit development. Before we can dive into creating ARM shellcode and build ROP chains, we need to cover some ARM Assembly basics first. ... The Intel x86 and x86-64 series of processors use the ...

The book has extensive coverage of interfacing assembly and C code and so might be of interest to C programmers who want to learn about how C works under the hood. All the examples use the free NASM (Netwide) assembler. The tutorial only covers programming under 32-bit protected mode and requires a 32-bit protected mode compiler.

Sep 12, 2012 · Note: All the code in this post was compiled on an x86_64 CPU running Mac OS X 10.8.1 using Clang 4.0 with optimizations disabled (-O0). Learning assembly with GDB. Let’s start by disassembling a program with GDB and learning how to read the output. Type the following program into a text file and save it as simple.c:

The following x86 assembly language instruction reads (loads) a 2-byte object from the byte at address 4096 (0x1000 in hexadecimal) into a 16-bit register called 'ax': mov ax , [ 1000 h ] In this assembly language, square brackets around a number (or a register name) mean that the number should be used as an address to the data that should be used.
