Ghc garbage collection

Web2.2 Garbage Collection in GHC GHC currently uses a generational, copying, stop-the-world garbage collector [10]. While there have been attempts to introduce concurrent and per-core garbage collectors [5, 9], they have been abandoned due to complexity. The collector used in GHC uses a block-structured heap so that it does not have to be ... WebGarbage collection (GC) needs to occur when there are known, stable pointers to the set of 'root objects' that can be traversed. At certain points in the program, this condition is satisfied. These points are called safe points, and the program can be stopped so GC can occur safely. For GHC, allocating any amount of memory is a safe point.
