With "available at runtime", I guess you mean "will it be part of 
the object file". In that case: yes. Because even if a function 
is _never_ called, it will be part of the object file (it must 
be).

For templated functions, the answer is not so easy. Templates 
that are only instantiated during CTFE are usually also emitted 
into the object file. But, when importing a templated function 
from another module, the template instantiation is not emitted to 
the object file if the compiler deduces that the instantiation is 
already emitted in the object file result of compiling the 
imported module (to avoid unnecessary duplicate instantiations 
across compilation units).
