Andreas Kling	c6e54d2a49	LibJS: Simplify Heap::mark_live_cells() ... Instead of iterating over every single cell, simply iterate over the live cells and mark them from there. Thanks to Blam for suggesting this! :^)	2020-03-09 19:36:15 +01:00
Stephan Unverwerth	1207187e97	LibJS: GC: Remove clear_all_mark_bits() ... Clearing all marked flags has been integrated into the sweep function, saving an additional full iteration over the heap.	2020-03-09 07:32:09 +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
