This repository contains a copy of Jikes RVM patched with an implement of the region-based garbage collection algorithm.
The implementation includes:
- parallel marking
- updating collection set
- parallel evacuation
We provide a RegionSpace, the file is under MMTk/src/org/mmtk/policy, which defines the policy of managing a heap as mutiple regions. To allocate objects to this region, we provide a modified version of BumpPointer. The space can be extended to a garbage first GC or any other region-based like GCs.
MMTk provides us the bindings to manage the memory in JikesRVM.
The official Jikes RVM website and repository can be found here.
