Priority of constructors and destructors

For constructors, destructors and interruptors, the linker generates a table of addresses sorted by increasing numeric value of the priorities (if not otherwise specified by the ORDER attribute in the linker config file). The library routines that process these tables work from rear to front. This means that routines with a higher numeric priority value are called first.
