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. -- vda - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
