--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Actually, std::trivially_relocate is not constexpr and std::relocate, while constexpr, documents that if consteval it performs always the move construction + destruction of each elt. As we don't do the vtbl signing, I think it might be perfectly fine to use #if __has_builtin (__builtin_trivially_relocate) use __builtin_trivially_relocate for clang or if GCC ever decides to do vtbl signing #else __builtin_memmove (...); #endif
