Consider a large-scale software project that heavily utilizes templates and generic programming. With an impending deadline, the compilation time is becoming a significant bottleneck. Which C++ feature/technique might be best suited to reduce compilation times without altering runtime performance?
- Decrease template depth
- Explicit template instantiation
- Use dynamic polymorphism
- Use of inline functions
Explicit template instantiation can help reduce compilation times by instructing the compiler to instantiate the templates in a specific source file rather than whenever they're used. This can help reduce redundancy and speed up the compilation of large projects that heavily rely on templates.
