For example, in the x86_64 small code model, one call only use the 32-bit PC relative call to make calls within the same DLL. When calling a function residing in a different DLL, one still has to use a 64-bit safe relocation, which amount to either loading the 64-bit address directly, loading it for a GOT table or jumping to a PLT stub containing the 64-bit call.
