How are you planning to track assignment a pointer to the young
generation in
the old generation ? Because if you plan to rescan the whole old
generation,
this is not exactly a generational GC.
A lot of benefit simply came from compacting all the remaining used
allocations together, essentially defragging the memory.
What you are describing is a compacting GC and not a generational GC.
Please just describe in words how you would do a generational GC without
write barriers. Because just as deadalnix wrote, the problem is tracking
pointers within the old generation that point to the new generation.
