There are many functions in my source code. If some functions don't be used in current target. There are some warning message about "Uncalled Segment" after compling. And these uncalled segments also occupy code memory. Does not have any method to avoid occupying code size by these Uncalled Segment. I don't want to use "#if(0)" to pre-disable this function.Does have any way to solve this issue except using "#if(0)"?
