Overview
This tutorial will build up a sophisticated garbage collector from scratch, starting with the empty shell that is the NoGC "collector" in MMTk (collector is a misnomer in this case since NoGC does not collect), and gradually adding functionality.
This tutorial will tell you the mechanics of building a collector in MMTk. It will tell you how but it does not tell you anything about why. The tutorial thus serves two purposes: 1) to give you some insight into the mechanics of MMTk (but not the underlying reasons or design rationale), and 2) show you that the mechanics of building a non-trivial GC in MMTk is not hard, hopefully giving you confidence to start exploring MMTk more deeply.
