All about 64-bit programming in one place

Very comprehensive collection of information about 64-bit programming:

By Andrey Karpov,

In this post I’ve collected a lot of links on the topic of 64-bit C/C++ software development. These include my articles and articles by my colleagues in the sphere of developing safe and efficient 64-bit code; FAQ’s and a training course. There are also many reviews of third-party articles on 64-bit software development. Enjoy yourself studying the materials.

2. Lessons on development of 64-bit C/C++ applications

Main page:

The course is composed of 28 lessons devoted to introduction to 64-bit systems, issues of building 64-bit applications, methods of searching errors specific to 64-bit code and code optimization. Such questions are also considered as estimate of the cost of moving to 64-bit systems and rationality of this move.

The contents of the course:

  • Lesson 01. What 64-bit systems are.
  • Lesson 02. Support of 32-bit applications.
  • Lesson 03. Porting code to 64-bit systems. The pros and cons.
  • Lesson 04. Creating the 64-bit configuration.
  • Lesson 05. Building a 64-bit application.
  • Lesson 06. Errors in 64-bit code.
  • Lesson 07. The issues of detecting 64-bit errors.
  • Lesson 08. Static analysis for detecting 64-bit errors.
  • Lesson 09. Pattern 01. Magic numbers.
  • Lesson 10. Pattern 02. Functions with variable number of arguments.
  • Lesson 11. Pattern 03. Shift operations.
  • Lesson 12. Pattern 04. Virtual functions.
  • Lesson 13. Pattern 05. Address arithmetic.
  • Lesson 14. Pattern 06. Changing an array’s type.
  • Lesson 15. Pattern 07. Pointer packing.
  • Lesson 16. Pattern 08. Memsize-types in unions.

  • Lesson 20. Pattern 12. Exceptions.
  • Lesson 21. Pattern 13. Data alignment.
  • Lesson 22. Pattern 14. Overloaded functions.
  • Lesson 23. Pattern 15. Growth of structures’ sizes.
  • Lesson 24. Phantom errors.
  • Lesson 25. Working with patterns of 64-bit errors in practice.
  • Lesson 26. Optimization of 64-bit programs.
