This post is also available on Sy Brand’s blog C++17 merged in a paper called Guaranteed copy elision through simplified value categories. The changes mandate that no copies or moves take place in some situations where they were previously allowed, e.g.: struct non_moveable { non_moveable() = default; non_moveable(non_moveable&&) = delete; }; non_moveable make() { return […]| C++ Team Blog
We have been investing in the quality of MSVC Address Sanitizer (ASan) in several key areas over the past year, including working with LLVM upstream to stay coordinated with their changes, adding coverage for internal tools and libraries, and hardening APIs and runtime modes. Upstreaming to LLVM MSVC ASan is derived from a fork of […]| C++ Team Blog
