Abstract

Interest in metaprogramming, reflection, and compile-time evaluation continues to inspire and foster innovation among the users and designers of the C++ programming language. Regrettably, the impact on compile-times of such features can be significant; and outside of build systems, multi-core parallelism is unable to bring down compilation times of individual translation units. We present ClangOz, a novel Clang-based research compiler that addresses this issue by evaluating annotated constant expressions in parallel, thereby reducing compilation times.
