Andreas Kling	6089d6566b	LibJS: Make it possible to go from a Cell* to its Heap& ... This patch makes all HeapBlock allocations aligned to their block size, enabling us to find the HeapBlock* for a given Cell* by simply masking bits off of the cell address. Use this to make a simple Heap& getter for Cell, which lets us avoid plumbing the Heap& everywhere.	2020-03-13 11:08:16 +01:00
Andreas Kling	63e4b744ed	LibJS: Add a basic mark&sweep garbage collector :^) ... Objects can now be allocated via the interpreter's heap. Objects that are allocated in this way will need to be provably reachable from at least one of the known object graph roots. The roots are currently determined by Heap::collect_roots(). Anything that wants be collectable garbage should inherit from Cell, the fundamental atom of the GC heap. This is pretty neat! :^)	2020-03-08 19:23:58 +01:00
