For each function that is only called during compilation (e.g. for code generation), at the top add:if (!__ctfe) return; That's it. For one project, this brought compilation time (with optimizations) from over an hour down to seconds! As it turns out, DMD will codegen all functions, even templated ones when they're instantiated, whether they're called by something or not. With metaprogramming-heavy code, it's easy to run into some optimizer performance corner cases, however this may make an impact regardless.
That's interesting. cc Dmitry, perhaps adding that to ctRegex would be helpful. -- Andrei
