PVS-Studio 7.19: C++ analyzer now works better with QNX compilers and Unreal Engine 5

By Andrey Karpov | Jun 24, 2022 02:06 AM | Tags: unreal engine 5 ue5 sast qnx pvs-studio

Recently, we have released a new PVS-Studio version — 7.19. In this note, we'll tell you about new features in the analyzer, the enhanced documentation, as well as what to read and... what to play.

PVS-Studio 7.19: what's new?

by Sergey Vasiliev

From the article:

Now, you can use PVS-Studio to analyze projects on Unreal Engine 5. For the most part, projects on UE 5 are analyzed in the same way as projects on UE 4. The difference is described in the documentation.

Introducing Scapix - automatic C++ bindings generator -- Boris Rasin

By Boris Rasin | Jun 9, 2022 01:30 PM | Tags: None

Using C++ with other languages.

Scapix Language Bridge - seamless integration of C++ with other languages

by Boris Rasin

From the article:

Bindings automatically generated directly from C++ headers during build - no need to manually maintain separate IDL definitions or manual bindings. Make a change in your C++ code, press build, then call your new code from Java, Objective C, Swift, Python, JavaScript or C#. Often this would be done in the same IDE, allowing continuous seamless cross-language development.

HPX V1.8.0 released -- STE||AR Group

By Hartmut Kaiser | May 25, 2022 07:59 AM | Tags: performance parallelism heterogeneous computing distributed computing concurrency c++23 c++20 c++17 c++14 c++11

The STE||AR Group has released V1.8.0 of HPX -- A C++ Standard library for Concurrency and Parallelism.

HPX V1.8.0 Released

We have released HPX 1.8.0 -- a major update to our C++ Standard Library for Concurrency and Parallelism. The HPX parallel algorithms now have been fully adapted to C++20, all existing facilities have been adjusted to conform to this version of the Standard as well. We now can proudly announce full conformance to the C++20 concurrency and parallelism facilities. HPX supports all of the algorithms as specified by C++20. On top of that we support parallel versions of all range-based algorithms and have added support for explicit vectorization to more of our algorithms (using std::experimental::simd). Much work has been done towards implementing P2300 (std::execution) and the underlying senders/receivers facilities. Last but not least, we have finished the refactoring of the whole library into a rather large set of non-cyclically depending components. Finally, the new release comes with a brand new documentation interface!

You can download the release from our releases page or check out the 1.8.0 tag using git. A full list of changes can be found in the release notes.

HPX is a general-purpose parallel C++ runtime system for applications of any scale. It implements all of the related facilities as defined by the C++20 Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 and C++20 parallel algorithms, including a full set of parallel range-based algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the features related parallelism and concurrency as specified by the upcoming C++23 Standard, the C++ Concurrency TS, Parallelism TS V2, data-parallel algorithms, executors, and many more. It also extends the existing C++ Standard APIs to the distributed case (e.g., compute clusters) and for heterogeneous systems (e.g., GPUs).

HPX seamlessly enables a new Asynchronous C++ Standard Programming Model that tends to improve the parallel efficiency of our applications and helps reducing complexities usually associated with parallelism and concurrency.

 

MSVC’s STL Completes /std:c++20--Casey Carter

All the reasons to try it!

MSVC’s STL Completes /std:c++20

by Casey Carter

From the article:

We are happy to announce that the final C++20 Standard Library features are now stabilized and available in /std:c++20 mode in both Visual Studio 2022 version 17.2 and Visual Studio 2019 version 16.11.14. This notably includes several proposals approved as Defect Reports (DRs) by the C++ Standard Committee against the C++20 Standard Library that made extensive design changes to <format> and <ranges> as recently as October 2021. You can now use the complete list of C++20 features in production in a binary compatible way with other supported language version modes...

New C++ features in GCC 12--Marek Polacek

Time to update.

New C++ features in GCC 12

by Marek Polacek

From the article:

Version 12.1 of the GNU Compiler Collection (GCC) is expected to be released in April 2022. Like every major GCC release, this version will bring many additions, improvements, bug fixes, and new features. GCC 12 is already the system compiler in Fedora 36. GCC 12 will also be available on Red Hat Enterprise Linux in the Red Hat Developer Toolset (version 7) or the Red Hat GCC Toolset (version 8 and 9).

Like the article I wrote about GCC 10, this article describes only new features affecting C++.

We implemented several C++23 proposals in GCC 12. The default dialect in GCC 12 is -std=gnu++17; to enable C++23 features, use the -std=c++23 or -std=gnu++23 command-line options. (The latter option allows GNU extensions.)

Note that C++20 and C++23 features are still experimental in GCC 12...

Execution and Static Analysis Support for MSVC on Compiler Explorer--Sy Brand

Execution and Static Analysis Support for MSVC on Compiler Explorer

by Sy Brand

From the article:

Compiler Explorer is a popular resource for visualizing the assembly output of various compilers, trying out different compiler versions and flags, and testing many popular libraries.

We’re pleased to announce that, as of today, code execution and static analysis are now available for MSVC on Compiler Explorer. Execution on CE has been one of our highest voted tickets on Developer Community, so we hope many of you will find it useful. The static analysis tool provided is the same as offered in GitHub Actions and in the IDE as background code analysis...

Outcome enters sustaining phase, goes ABI stable

by Niall Douglas

From the article:

After three years of maturing, I am pleased to announce that the Spring release of Outcome, an alternative error handling framework, will enter its sustaining phase and thus it will be able to formally guarantee ABI stability going forth. ABI stability is tested per commit by CI and the specifics of the guarantees is documented here...

What's new in PVS-Studio in 2021?

By Andrey Karpov | Dec 31, 2021 08:06 AM | Tags: unreal engine pvs-studio misra clion

2021 is coming to an end, which means it's time to sum up the year! Today we'll tell you about the new features we added to PVS-Studio in the past year. Buckle up and let's go!

What's new in PVS-Studio in 2021?

by Maxim Stefanov, Oleg Lisiy, Sergey Vasiliev

From the article:

PVS-Studio has plugins for various JetBrains IDEs: Rider, IntelliJ IDEA. Somehow we missed another popular IDE — CLion. Our clients expressed an increasing interest in this feature. Moreover, the PVS-Studio plugin for CLion as a cross-platform IDE would make it possible to work comfortably with the C++ analyzer regardless of the environment in which the developer works: on Windows, Linux or macOS.
