CCS/CC3235MODASF: Static library: is it possible to avoid having an unused function linked

Part Number: CC3235MODASF

Tool/software: Code Composer Studio

Hi,

I am developing a static library to avoid code duplicates within three similar products.

The products are using cc3235 and cc3220 and are built with ccs 9.3 with compiler 18.12.4.

In the static library, I want to put a function which has just a small part which varies for the different projects. 

See below an example which I hope to be understandable enough ; )

//Static lib project

extern void product1Function();
int genericFunction(bool isProduct1)
{
   // do something generic

    if (isProduct1)
    {
        product1Function()
    }
}




//Product1 project

void product1Function()
{
   //Do something
}

void main()
{
    genericFunction(true)
}


//Product2 project
void main()
{
    genericFunction(false)
}

In Product2 project, I currently get the error Unresolved symbol product1Function. Is it possible to have the linker understand that this will never be called and remove the whole non callable chunk?

Thanks,

Cédric
