# Assembly My assembly language exercises from the book Introduction to 64 Bit Assembly Language Programming for Linux and OS X Third Edition by Ray Seyfarth Book web site: I'm doing all of my work on an Oracle Enterprise Linux 7.3 virtual machine running on VirtualBox on my laptop. Assemble: yasm -f elf64 -P././ebe/ebe.inc -g dwarf2 -l ex1.lst ex1.asm Link with start: ld -o ex1.exe ex1.o Link with main: gcc -o ex2.exe ex2.o I found what seems to be a bug in yasm related to debugging. I discussed this on Stackoverflow in this thread: I redid chapter 9 exercise 2 using nasm and plan to use nasm instead of yasm as my assembler to see if it works better with gdb the debugger. Here is the nasm command I'm using: nasm -f elf64 ex1.asm -o ex1.o -l ex1.lst -g -F dwarf; ld -o ex1.exe ex1.o; gdb ex1.exe Note that I also left off the ebe.inc parameter. I have been using gdb only and not the ebe utility that the book recommends. It is just easier for me to do everything command line through putty. Also, I think that nasm may be a little more widely used than yasm so I don't mind switching over in case I do anything with x86-64 assembly after working through this book. This book introduces programmers to 64 bit Intel assembly language using the Microsoft Windows operating system. The book also discusses how to use the free integrated development environment, ebe, designed by the author specifically to meet the needs of assembly language programmers. Ebe is a C++ program which uses the Qt library to implement a GUI environment consisting of a source window, a data window, a register window, a floating point register window, a backtrace window, a console window, a terminal window, a project window and a pair of teaching tools called the 'Toy Box' and the 'Bit Bucket'. The source window includes a full-featured text editor with convenient controls for assembling, linking and debugging a program. The project facility allows a program to be built from C source code files and assembly source files. • “Introduction to 64 Bit Assembly Programming for Linux and OS X: Third Edition” by Ray Seyfarth • Optional book for the class, to give you alternative explanations to my own • When you see “Book” page references in the bottom of slides, it is referring to this book. Introduction to 64 Bit Assembly Language Programming for Linux and OS X The era of 64 bit computing is now. You know your computer will run faster with more RAM than 4 GB and a 32 bit computer is limited to 4 GB.

Assembly is performed automatically using the yasm assembler and linking is performed with ld or gcc. Debugging operates by transparently sending commands into the gdb debugger while automatically displaying registers and variables after each debugging step. The Toy Box allows the use to enter variable definitions and expressions in either C++ or Fortran and it builds a program to evaluate the expressions. Then the user can inspect the format of each expression. The Bit Bucket allows the user to explore how the computer stores and manipulates integers and floating point numbers. Additional information about ebe can be found at The book is intended as a first assembly language book for programmers experienced in high level programming in a language like C or C++. The assembly programming is performed using the yasm assembler automatically from the ebe IDE under the Linux operating system. The book primarily teaches how to write assembly code compatible with C programs. The reader will learn to call C functions from assembly language and to call assembly functions from C in addition to writing complete programs in assembly language. The gcc compiler is used internally to compile C programs. The book starts early emphasizing using ebe to debug programs. Being able to single-step assembly programs is critical in learning assembly programming. Ebe makes this far easier than using gdb directly. Highlights of the book include doing input/output programming using Windows API functions and the C library, implementing data structures in assembly language and high performance assembly language programming. Early chapters of the book rely on using the debugger to observe program behavior. After a chapter on functions, the user is prepared to use printf and scanf from the C library to perform I/O. The chapter on data structures covers singly linked lists, doubly linked circular lists, hash tables and binary trees. Test programs are presented for all these data structures. There is a chapter on optimization techniques and 3 chapters on specific optimizations. One chapter covers how to efficiently count the 1 bits in an array with the most efficient version using the recently-introduced popcnt instruction. Another chapter covers using SSE instructions to create an efficient implementation of the Sobel filtering algorithm. Free download word games for mac. The final high performance programming chapter discusses computing correlation between data in 2 arrays. There is an AVX implementation which achieves 20.5 GFLOPs on a single core of a Core i7 CPU. A companion web site, has a collection of PDF slides which instructors can use for in-class presentations and source code for sample programs.
