Memory safety is quickly changing from a luxury to a necessity, driven by increased security requirements and regulatory pressure. In this workshop, we'll bring together practitioners, developers, and enthusiasts interested in supporting memory safety in the context of Clang and LLVM. This includes techniques that improve the memory safety and security of C and C++ programs (like static analysis, dynamic mitigations and best practices), representing and optimizing memory-safety constructs, and interoperation across languages. The workshop will be a mix of talks and hands-on activities (like roundtables), with the goal of fostering community, sharing knowledge and kickstarting collaboration.
