Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- If you want to ensure a function is evaluated at compile time, it needs to be either C++20 consteval, or you need to evaluate it in constant expression context, e.g. constexpr auto x = expensive_function(10000);
