Smarter, workspace-aware code completions for C++ in VS Code
C++ code understanding Developing C++ code can be complex. C++ project structure, style, and convention can vary widely from repository to repository, and critical context for a given task often spans multiple files. This can require C++ developers to open and navigate across several files to fully understand a given project and author new code. The GitHub Copilot team has focused on two areas to improve the C++ developer experience for code completions: These improvements are designed to help the autocomplete-style inline GitHub Copilot code completions be even more productive with C++ coding, m...

Address Sanitizer Updates for Visual Studio 2022 Version 17.14
Introduction It has been an exciting few months for the Address Sanitizer (ASan) since our last update. In addition to our continuous focus on quality and correctness, our internal “dogfooding” (i.e. internal adoption) effort has reached several important milestones. In this update, I want to go over some of the quality improvements since Visual Studio 2022 version 17.13, and to give a peek into how ASan is now protecting our C++ toolset against memory safety errors during development. Some improvements in Visual Studio 2022 version 17.14 This release also contains several other impr...

Introducing the /forceInterlockedFunctions switch for ARM64
In Visual Studio 2022 17.14, we are introducing the switch, which generates and links with out-of-line atomics that select Armv8.1+ Large System Extension (LSE) atomic instructions based on CPU support. This switch is on by default for Armv8.0 and off for Armv8.1+. Outlining is necessary in Armv8.0 because this version's interlocked intrinsics use exclusive instructions—/—that do not guarantee forward progress. This can cause performance issues due to intermittent livelocks. See Arm Architecture Reference Manual for A-profile architecture, section "B2.17.5 Load-Exclusive and Store-Exclusive instruction usage ...
