What Can Compiler Benchmarks Reveal About Metaprogramming Implementation Strategies - CppCon 2022

Explore the intricacies of compiler benchmarks and their implications for metaprogramming implementation strategies in C++ in this CppCon 2022 conference talk. Dive into the development of reliable portable benchmarks for compilers using advanced metaprogramming constructs in C++20 and C++17. Examine the results of supercomputer-generated benchmarks to analyze the real costs of class templates, function templates, generic lambdas, value-based metaprogramming, and concepts on compile-time for various compilers and versions. Gain insights into optimal metaprogramming patterns for maximizing compile-time performance and understand the current state of compile-time optimization in modern compilers.
