Issues of 64-bit code in real programs: virtual functions
By Andrey Karpov (17 posts) on November 23, 2009 at 4:03 pm
Comments (0)
So, if you download the demo-version of this library, install it and search the word "WinHelp" through .h-files… you will see that everywhere this function is supposedly overlapped, DWORD parameter is used instead of DWORD_PTR. And this means that Help system in these classes will behave incorrectly on a 64-bit system.

Magic constants and malloc() function
By Andrey Karpov (17 posts) on November 17, 2009 at 11:15 am
Comments (0)
Once again I would like to discuss the issue of using magic constants in code. We can eternally repeat that one should use sizeof() operator for correct calculation of the size of memory being allocated. But both this knowledge and correct writing of a new code will not help you detect an error already existing in the maze of the old code in large projects.

I'm presently attending the Microsoft PDC 2009 conference and I am today in the Patterns of Parallel Programming workshop. It appeared that the workshop was being recorded and so I sent an e-mail to some of the PDC 2009 organizers and can confirm that the Patterns of Parallel Programming workshop recording will be available to all attendees. Richard [...]

With the Intel(R) Embedded Software Development Tool Suite 2.1.008 update release from early November Intel started supporting the Macraigor Systems* usb2Demon device (check out their website at http://www.macraigor.com/intel/). This low cost JTAG system debug device supporting the Intel(R) Atom(TM) processor z5xx and N2xx platforms for embedded and custom platform operating system and software stack [...]

Are "64-bit errors" real?
By Andrey Karpov (17 posts) on November 11, 2009 at 8:51 am
Comments (0)
I often hear in various interpretations the phrase: "The given examples show not the code incorrect from the viewpoint of porting to x64 systems, but the code incorrect in itself". I would like to discuss and theorize a bit on this point in the blog. Please, take this note with a bit of humor.

Problems of 64-bit code in real programs: magic constants
By Andrey Karpov (17 posts) on November 10, 2009 at 4:37 pm
Comments (0)
The error described deserves attention because of its simplicity or even ingenuousness. It has been recommended in all the books for many years not to use magic constants in code. Everyone knows about it and mentions it in coding standards. But in practice magic numbers appear in various code sections again and again.

Testing of Linux-applications with the help of PVS-Studio in Windows
By Andrey Karpov (17 posts) on November 10, 2009 at 4:37 pm

By default, Viva64 code analyzer (and now PVS-Studio) is oriented on LLP64 data model being intended for operation in Windows environment. Roughly speaking, it means that it searches incorrect shared use of size_t-types and int-types. To test the code on correctness in 64-bit Linux-environment you need to search incorrect shared use of long-types and int-types as well.

PVS-Studio and testing Loki
By Andrey Karpov (17 posts) on November 9, 2009 at 8:40 am

In PVS-Studio 3.10, support parsing of complex constructions based on templates will be improved what will allow you to efficiently search errors even in the code of those programs which use complex template libraries such as Loki.

Hi All, If you are going to the event next week in Berlin then let me know about it. Maybe we can meet face to face and if there are enough of us perhaps even a gourp community meeting. This can be a good opportunity to meet the experts. In any case, you are all welcome to [...]

Change of type alignment and the consequences
By Andrey Karpov (17 posts) on November 5, 2009 at 2:56 pm
Comments (0)
When porting software one of the task a developer faces is to change types' sizes and rules of their alignments. Not so long ago we provided support of the diagnosing rule allowing you to detect data structures which use memory on 64-bit inefficiently in Viva64 analyzer. But there is still some research work to be [...]

Memory management challenges in parallel applications
By Roman Lygin (Intel) (3 posts) on October 28, 2009 at 6:18 am
Comments (4)
Let me share some recent practical experience with memory management issues when developing a multi-threaded application. This can probably be a rather common case (as recent post by Roman Dementiev and its follow up discussion demonstrates), and I’d be happy if my experience were helpful for others. Working on CAD Exchanger I am designing one of [...]
