Hello, I'm reading the GC code recently, but I didn't find any code about analyzing whether an object is reachable or not (or say whether a pointer is live), can someone give me some hints?
I see that each heap word corresponds to a heapBits. By doing & operation with bitscan and bitPointer we can judge whether it has more pointers and whether it is a pointer, but do we need to judge whether a pointer is live? For example, we apply for a piece of memory in a function, do some calculations through a pointer, and then return from the function, assuming that this piece of memory is useless. In the next GC, how to determine that the pointer in this function is dead and we can reclaim this memory?
