Priority of constructors, destructors, and interruptors

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 those tables work from rear to front. That means that routines with a higher numeric priority value are called first.
