Debug C++ Without Running

Explore debugging techniques for C++ code without execution in this ACCU 2018 conference talk. Delve into strategies for handling macros, templates, compile-time evaluation, code generation, reflection, and metaclasses. Learn how to navigate complex C++ features that often obscure the final code passed to the compiler. Discover methods for dealing with preprocessor challenges and alternatives to traditional read-fix-run debugging cycles. Examine approaches for macro and typedef debugging, understanding hidden types with auto/decltype, and managing different code branches based on preprocessor conditions. Gain insights into tools and workflows that can enhance C++ development, including features implemented in CLion and ReSharper C++. Understand how these techniques can improve the creation of modern C++ code, especially in situations where local execution is not possible.
