Time to get familiar!

Using C++ Modules in MSVC from the Command Line Part 1

by Cameron DaCamara

From the article:

In this three-part series we will explore how to build modules and header units from the command line as well as how to use/reference them.

The goal of this post is to serve as a brief tour of compiling and using primary module interfaces from the command line and the options we use...

CLion 2021.2: CMake Presets, GNU Autotools Projects, Debugger Updates, Lifetimes Analysis

CLion 2021.2 is here, helping you keep up with the changing C++ ecosystem!

CLion 2021.2: CMake Presets, GNU Autotools Projects, Debugger Updates, New Static Analysis, and More

by Anastasia Kazakova

From the article:

The C++ ecosystem is evolving, and so too is our cross-platform C/C++ IDE. CLion 2021.2 can help you by protecting your code from typical C++ memory safety issues, simplifying your build configurations, and making debugging easier and more effective.

  • Project models
    • Initial support for CMake Presets
    • CMake New Project templates
    • Support for GNU Autotools projects and Make preconfiguration steps
  • Debugger
    • Relaxed breakpoints, and breakpoints in disassembly view
    • Preview tab for the debugger
    • Remote LLDB and bundled LLDB 12
    • Better Natvis support and support for minidumps on Windows
    • FreeRTOS thread view
  • Lifetimes analysis, for catching common issues like dangling pointers and escaping from a local scope
  • Integration with Cling, an interactive C++ interpreter
  • Profiling in remote mode and on WSL
  • Easier Docker and WSL configuration
  • Text search in Local History and many VCS updates
  • Localized CLion UI in Chinese, Korean, and Japanese

HPX V1.7.0 released -- STE||AR Group

By Hartmut Kaiser | Jul 14, 2021 12:28 PM | Tags: performance parallelism heterogeneous computing distributed computing concurrency c++20 c++17 c++14 c++11

The STE||AR Group has released V1.7.0 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.7.0 Released

The newest version of HPX (V1.7.0) is now available for download! This release continues the focus on C++20 conformance with multiple new algorithms adapted to be C++20 conformant and becoming customization point objects (CPOs). We’ve also added experimental support for using GCC’s SIMD data types with our parallel algorithms. Finally, we've implemented a large subset of sender/receiver functionality based on current proposals (mainly P0443, P1897, and P2300). HPX futures fulfill the sender concept, and senders can explicitly be turned into futures, which means that codebases can gradually adopt senders where appropriate. The full list of improvements, fixes, and breaking 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++ Standard. As of this writing, HPX provides one of the only widely available open-source implementation of the new C++17 parallel 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++20 Standard, the C++ Concurrency TS, Parallelism TS V2, data-parallel algorithms, executors, senders/receivers 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.

 

Beta-Testing of PVS-Studio Plugin for JetBrains CLion

By Andrey Karpov | Jun 29, 2021 05:27 AM | Tags: static code analyzer sast pvs-studio jetbrains clion

To fully test the plugin, you'll need to install both the beta plugin version and the C++ core beta version of the analyzer. There are several ways to install the plugin: from the official repository, from the repository on our site, or using Windows PVS-Studio installer. Below we'll tell you in detail how to do this.

Beta-Testing of PVS-Studio Plugin for JetBrains CLion

by Evgeniy Ovsyannikov, Paul Eremeev

From the article:

We usually recommend running full analysis regularly, such as once a day, at night. In addition to nightly analysis, we highly recommend checking new code immediately after writing it. This way you'll get the best advantage of using the analyzer. To do this, use incremental analysis, which works as follows. A project was changed, a developer runs a build. After successful compilation only modified files will be analyzed. Modified files are the ones that have been changed since the previous analysis.

Ready to be used.

<format> in Visual Studio 2019 version 16.10

by Charlie Barto

From the article:

C++20 adds a new text formatting facility to the standard library, designed primarily to replace snprintf and friends with a fast and type safe interface. The standardized library is based on the existing {fmt} library, so users of that library will feel at home.

Before diving into how std::format works I want to thank Victor Zverovich, Elnar Dakeshov, Casey Carter, and miscco, all of whom made substantial contributions to this feature, and were the reason why we could complete it so quickly...

PVS-Studio Team: Switching to Clang Improved PVS-Studio C++ Analyzer's Performance

By Andrey Karpov | Jun 1, 2021 07:01 AM | Tags: pvs-studio performance msvc llvm clang

Although the project's preparation took a while, we were satisfied that the analyzer's performance grew by over 10%. We will use Clang to build future releases of PVS-Studio for Windows.

PVS-Studio Team: Switching to Clang Improved PVS-Studio C++ Analyzer's Performance

by Alexey Govorov and Sergey Larin

From the article:

From the earliest days, we used MSVC to compile the PVS-Studio C++ analyzer for Windows - then, in 2006, known as Viva64, version 1.00. With new releases, the analyzer's C++ core learned to work on Linux and macOS, and we modified the project's structure to support CMake. However, we kept using the MSVC compiler to build the analyzer's version for Windows. Then, in 2019, on April 29th, Visual Studio developers announced they had included the LLVM utilities and Clang compiler in the IDE.

 

PVS-Studio 7.13: Blame Notifier, MISRA

By Andrey Karpov | May 31, 2021 07:11 AM | Tags: sast pvs-studio misra json devsecops devops autosar

The list of diagnostics supported by MISRA and AUTOSAR continues to grow. We've expanded the Blame Notifier utility's capabilities. The analysis of Ninja projects on Windows has been enhanced and now involves the JSON Compilation Database.

PVS-Studio 7.13

by Andrey Karpov

From the article:

  • The C++ analyzer provides enhanced support of Ninja projects on Windows using JSON Compilation Database (compile_commands.json).
  • The C++ PVS-Studio analyzer spends 10% less time checking source files with the use of the Clang compiler.
  • To check C++ and C# Visual Studio PVS-Studio_Cmd.exe projects, you can pass the suppression file directly. Before this, you could add suppressed warnings only at the projects and solution level.
