In this video, we review GH-2158: https://github.com/microsoft/STL/pull..., titled “Extend memcpy, memmove and memcmp optimizations.” Microsoft’s Visual C++ Standard Library (MSVC STL) is now open-source and maintainers of the repository are frequently reviewing externally-contributed code changes. Every few weeks, maintainers review open pull requests (PRs) in a meeting with other members of the team, often including individuals from other MSVC-related teams. The purpose of these meetings is to provide insight into the STL’s reviewing process, encourage questions, and grow general knowledge about the STL codebase. ...more
