They are vaguely connected in a sense that unused function which is
not marked static doesn't generate gcc warning, but will be discarded
by --gc-sections. "make XYZ static" also tends to find them - you make
function static, you recompile the file, and gcc informs you that
the function is not used at all!

This happened to me when I did aic7xxx patches.

You may yse --print-gc-sections to see the list of discarded sections.
