QUESTION

I have a complex application with function pointers and code banking. To avoid correcting all the function references, I have used the linker directive NOOVERLAY, but I still get the following linker warning:

WARNING L16: UNCALLED FUNCTION, IGNORED FOR OVERLAY PROCESS

How can I avoid this warning?

ANSWER

When you use function pointers and code banking, the linker needs exact information about the call tree of your program. This information is required to determine the function calls that require an entry in the INTER-BANK CALL TABLE. Without this information, the linker cannot ensure that the correct code bank is selected for a function that is indirectly called from a different code bank. Therefore, it is also essential that you supply correct call tree information for a code banking application.
