Overview of this book

The Assembly language is the lowest level human readable programming language on any platform. Knowing the way things are on the Assembly level will help developers design their code in a much more elegant and efficient way. It may be produced by compiling source code from a high-level programming language (such as C/C++) but can also be written from scratch. Assembly code can be converted to machine code using an assembler. The first section of the book starts with setting up the development environment on Windows and Linux, mentioning most common toolchains. The reader is led through the basic structure of CPU and memory, and is presented the most important Assembly instructions through examples for both Windows and Linux, 32 and 64 bits. Then the reader would understand how high level languages are translated into Assembly and then compiled into object code. Finally we will cover patching existing code, either legacy code without sources or a running code in same or remote process.

Memory Addressing Modes

Thus far, we have gained some acquaintance with certain basic aspects of Assembly programming. We have covered the Intel Architecture basics, setting up the development environment of your choice, and the instruction set architecture (ISA).

We know what operations we are able to perform over different types of data, but all this is of very little value as long as we don't know how to retrieve and store data. Of course, we are familiar with the mov instruction, but without knowing how to address the data in memory, this instruction is quite useless.

Fortunately for us, Intel provides a very flexible mechanism for addressing data or code in memory. In this chapter, we will cover the following modes of memory addressing:
