CppCon 2021 Keynote: Value in a Procedural World -- Lisa Lippincott

From the announcement:

We’ve previously announced keynotes by Bjarne Stroustrup and Herb Sutter... We’re happy to announce: Lisa Lippincott will be in Aurora live, in person to deliver a brand-new talk about a fundamental basis of understanding computer programs.

Lisa Lippincott designed the software architectures of Tanium and BigFix, two systems for managing large fleets of computers. She is chair of the numerics study group of the C++ standardization committee...

Cppcon 2021 A (Short) Tour of C++ Modules--Danila Kutenin

Registration is now open for CppCon 2021, which starts on October 24 and will be held both in person and online. To whet your appetite for this year’s conference, we’re posting some upcoming talks that you will be able to attend this year. Here’s another CppCon future talk we hope you will enjoy – and register today for CppCon 2021 to attend in person, online, or both!

A (Short) Tour of C++ Modules

Tuesday, October 26 • 3:15pm - 4:15pm

by Danila Kutenin

Summary of the talk:

Once you decide to start a big project or a company, it eventually comes down to unifying the build infrastructure. However, hundreds and thousands of compilation units are extremely difficult to maintain to achieve the highest possible performance. Contrary to the belief that you should always trust your compiler, recent micro-architectural breakthroughs from merging two arrays with special instructions to JSON parsing through SIMD showed that compilers are far from understanding every single piece of code you write. In this session we will talk about our experience on how to achieve the highest possible performance without much rewriting of your code, which trade-offs C++ compilers have, how to make the most of your micro-architecture, why unrelated changes may decrease the performance and how to debug them. In the end we will show which compiler options gave us the opportunity to gain 5-15% of performance, stabilized the benchmarks and decreased the build size for search engines, databases and high performance computing.

Cppcon 2021 Back To Basics: Overload Resolution--Barbara Geller and Ansel Sermersheim

Back To Basics: Overload Resolution

Tuesday, October 26 • 9:00am - 10:00am

by Barbara Geller and Ansel Sermersheim

Summary of the talk:

During this talk we will explain the definition of a function overload and what rules the compiler follows to decipher which overload to call. The rules can be complex and may not always do what you expect. We will condense the C++ standard to the essential rules every programmer should be aware of in order to reason through overload resolution.

Knowing how overload resolution works will improve your ability to debug compiler errors and this is vital to write correct code. We will provide simple and concise explanations for various buzzwords like template argument deduction, implicit conversion, standard conversions, and tie-breakers.

This talk is part of the Back to Basics track and the material will be targeted to include all skill levels. Familiarity with C++ is recommended however no prior knowledge of function overloads is required.

Supercharge Your C++ analysis with SonarLint for CLion

By philsquared | Oct 4, 2021 11:04 AM | Tags: None

SonarSource recently released the SonarLint plug-in for CLion - this article looks at some of the interesting rules (checks) this gives you, and how each tool enhances the other.

Supercharge your C++ analysis with SonarLint for CLion

by Phil Nash and Geoffray Adde

From the article:

In this post, we want to demonstrate the powerful capabilities of the C++ analyzer with SonarLint (a free, in-IDE static analysis plugin) and highlight some unique and interesting rules that you might find useful. Through that lens, we want to show how you can leverage them to elevate your CLion’s inbuilt static analysis capabilities.

Code Analysis++

Tuesday, October 26 • 7:45am - 8:45am

by Anastasia Kazakova

Summary of the talk:

Martin Fowler once wrote that high-quality software is actually cheaper to produce than low-quality software. We agree with that sentiment, and we warmly welcomed the C++ Core Guidelines when they were introduced in 2015. Research and surveys conducted in the C++ Community consistently demonstrate the popularity of the Clang family of tools, as well as the growing demand for static analysis to be added to code editors.

In this talk, we’ll explore the current capabilities of existing C++ static analyzers and discuss some of the enforcements listed in the C++ Core Guidelines from a toolability aspect. We’ll also look into the recent “Simplify C++” trend in the language’s evolution, and to wrap things up we’ll take a look at how technology-specific analysis (like MISRA and AUTOSAR) is being adopted.

A variety of checks will be discussed, from catching a dangling pointer to conforming to the preferred code style and naming scheme. And I want to share a crazy idea I have about gamifying static analysis. Let’s play!

CWE Top 25 2021. What is it, what is it for and how is it useful for static analysis?

For the first time PVS-Studio provided support for the CWE classification in the 6.21 release. It took place on January 15, 2018. Years have passed since then and we would like to tell you about the improvements related to the support of this classification in the latest analyzer version.

CWE Top 25 2021. What is it, what is it for and how is it useful for static analysis?

by Mikhail Gelvih

From the article:

We have been using the CWE classification for PVS-Studio diagnostics for more than three years. Their number increases every year. In 2018, we covered only 94 points on the CWE list. Now it's almost 130. However, this article isn't about the total number of diagnostics. Let's talk about those that are included in the list of the most dangerous diagnostics in 2021. If you want to read the full list, you can get it in the "CWE compliance" section of our documentation.
