WebFeb 24, 2024 · This gives us O(1) complexity for allocations and deallocations, and practically 100% memory efficiency. All the allocator needs to store is a pointer to the top of the stack; for a 4K memory page this means 8 bytes of overhead on a 64bit system. That's pretty good! But so far our allocator can only operate on a fixed amount of memory. WebFeb 25, 2015 · Unfortunately we can’t naively use something like alloca() to allocate from the stack, because when a function returns that alloca() is used in, that stack memory is released.
