Improving the Performance of Standard Library Functions

Kirsten LeeJuly 30, 2019Jul 30, 201907/30/19

In Visual Studio 2019 version 16.2 we improved the codegen of several standard library functions. Guided by your feedback on Developer Community (Inlining std::lldiv and Improved codegen for std::fmin, std::fmax, std::round, std::trunc) we focused on the variants of standard division (std::div, std::ldiv, std::lldiv) and std::isnan.

Smarter Member List Filtering for C++

Nick UhlenhuthJuly 29, 2019Jul 29, 201907/29/19

We are always looking for ways to make you more productive while coding in Visual Studio. In Visual Studio 2019 version 16.2, we have created a smarter, more relevant Member List. Specifically, we now apply method filtering based on type qualifiers. To illustrate this, consider the following example: You have two vectors, but one is c

Improved Linker Fundamentals in Visual Studio 2019

Russell HadleyJuly 25, 2019Jul 25, 201907/25/19

On the C++ team we’ve heard loud and clear from users that build times are a pain point. We’ve continued our focus on improving the step, linking, that dominates F5 build times. Fast F5 build times, or iteration build times, are a key contributor to developer productivity and we felt that there was a large opportunity so we narrowed in on

Inlining Decisions in Visual Studio

Terry MahaffeyJuly 24, 2019Jul 24, 201907/24/19

Introduction My name is Terry Mahaffey and I work on the code generation team in MSVC. Lately I’ve been doing some work on our inliner and I wanted to give a brief introduction to it before later diving into some of the changes we’ll be shipping. Inlining is perhaps the most important optimization a compiler performs. In addition to re

Visual Studio 2019 version 16.2 Preview 3 includes built-in Clang/LLVM support for MSBuild projects. In our last release, we announced support for Clang/LLVM for CMake. In the latest Preview of Visual Studio, we have extended that support to also include MSBuild projects. While in most cases we recommend using the MSVC compiler, we are committ
