Consider the following code:
example% cat Example.cc template <class T> struct S { void imf() {} static void smf() {} }; template class S <int>; int main() { } example% |
When you specify -template=geninlinefuncs, even though the two member functions of S are not called in the program, they are generated in the object file.
