Does the GC look into this range and check for > the existence of pointers it's currently managing? yes. this adds GC "root". but normal GC root is just a single pointer, and "range root" as a memory region that will be scanned for pointers (i.e. something like "array of pointers"). note that scan is conservative, so if you happen to have some integer value that can be interpreted as pointer to GC-managed memory, it will be considered as pointer.
