Using `extern template` with third-party header-only library

QUESTION

Using `extern template` with third-party header-only library

Asked 2020-May-13 at 22:16

I am using the glm library, which is a header-only collection of math utilities intended for 3D graphics. By using -ftime-trace on Clang and ClangBuildAnalyzer, I've noticed that a lot of time is being spent instantiating glm types:

Unfortunately, there’s no way to avoid these instantiations. An explicit instantiation declaration of a class template doesn’t prevent (implicit) instantiation of that template; it merely prevents instantiating its non-inline, non-template member functions (which is often none of them!) because some other translation unit will supply the actual function symbols and object code.

It’s not that seeing the template definition causes instantiation (which specialization would be instantiated?). The reason is that code which requires that the class be complete still needs to know its layout and member function declarations (for overload resolution), and in general there’s no way to know those short of instantiating the class:

Install ClangBuildAnalyzer

Clang C/C++ build analysis tool when using Clang 9+ -ftime-trace. The -ftime-trace compiler flag (see blog post or Clang 9 release notes) can be useful to figure out what takes time during compilation of one source file. This tool helps to aggregate time trace reports from multiple compilations, and output "what took the most time" summary:.
Which files are slowest to parse? i.e. spend time in compiler lexer/parser front-end
Which C++ templates took the most time to instantiate?
Which files are slowest to generate code for? i.e. spend time in compiler backend doing codegen and optimizations
Which functions are slowest to generate code for?
Which header files are included the most in the whole build, how much time is spent parsing them, and what are the include chains of them?
