New Safety Rules in C++ Code Analysis

In Visual Studio version 16.8 Preview 3,  we are adding a few safety rules to C++ Code Analysis that can find some common mistakes, which can lead to bugs ranging from simple broken features to costly security vulnerabilities. These new rules are developed around issues discovered in production software via security reviews and...

Improving code generation time with C++ Build Insights

Code generation time is a significant contributor to total build time for optimized builds. During this step of the compilation process, source code is passed through several algorithms that transform your program into an optimized version that can be executed more efficiently. In general, the optimization of a C++ function happens quickly and...

Profiling template metaprograms with C++ Build Insights

The use of templates in C++ programs can sometimes lead to longer builds. C++ Build Insights puts tools at your disposal for analyzing template usage patterns and their associated impact on build time. In this article, we show you how to use the vcperf analysis tool and the C++ Build Insights SDK to understand and fix problematic template ...

Faster builds with PCH suggestions from C++ Build Insights

The creation of a precompiled header (PCH) is a proven strategy for improving build times. A PCH eliminates the need to repeatedly parse a frequently included header by processing it only once at the beginning of a build. The selection of headers to precompile has traditionally been viewed as a guessing game, but not anymore! In this article, ...

Finding build bottlenecks with C++ Build Insights

C++ Build Insights offers more than one way to investigate your C++ build times. In this article, we discuss two methods that you can use to identify bottlenecks in your builds: manually by using the vcperf analysis tool, or programmatically with the C++ Build Insights SDK. We present a case study that shows how to use these tools to speed up ...

Introducing C++ Build Insights

C++ builds should always be faster. In Visual Studio 2019 16.2, we’ve shown our commitment to this ideal by speeding up the linker significantly. Today, we are thrilled to announce a new collection of tools that will give you the power to make improvements of your own. If you've ever had time for breakfast while building C++, then you may ...

Linux Development with C++ in Visual Studio 2019: WSL, ASan for Linux, Separation of Build and Debug

In Visual Studio 2019 you can target both Windows and Linux from the comfort of a single IDE. In Visual Studio 2019 version 16.1 Preview 3 we announced several new features specific to the Linux Workload: native support for the Windows Subsystem for Linux (WSL), AddressSanitizer integration, and the ability to separate build and debug targets...
