  • Some examples of the 64-bit code errors

    23.07.2007
    While porting 32-bit software to 64-bit systems there may appear some errors in the code of applications which were written in C++ language. The cause for these hides in the alteration of the base data types (to be more exact, in the relations between them) with the new hardware platform. Read more

  • Static code analysis for verification of the 64-bit applications

    22.04.2007
    The coming of 64-bit processors to the PC market causes a problem which the developers have to solve: the old 32-bit applications should be ported to the new platform. After such code migration an application may behave incorrectly. The article is elucidating question of development and appliance of static code analyzer for checking out of the correctness of such application. Some problems emerging in applications after recompiling in 64-bit systems are considered in this article as well as the rules according to which the code check up is performed. Read more
