We have built all our own interface for all of our routines and would like ifort to check them for us. That is, tell us if there is a missing or incorrect interface. However, the only info/behavior I can find is to let the compiler generate interfaces or not. When we let it we get genmod interfaces for all routines whether we have one or not. Our interface mod file is built and used but I want the compiler to only generate an interface when ours in incorrect or missing. Is there a combination of compiler options that will get us that behavior?
A related question is whether we should be creating our own interfaces or not. Is it better to let the compiler generate them? If we let the compiler generate interfaces will we be warned if the same routine name is used with different argument lists or will the compiler somehow happily create two interfaces and leave us in the dark?
