 _A link register (LR for short) is a register which holds the address to return to when a subroutine call completes. This is more efficient than the more traditional scheme of storing return addresses on a call stack, sometimes called a machine stack. The link register does not require the writes and reads of the memory containing the stack which can save a considerable percentage of execution time with repeated calls of small subroutines.
 The IBM POWER architecture, and its PowerPC and Power ISA successors, have a special-purpose link register, into which subroutine call instructions put the return address._
