'Understanding Concurrent pre clean and card tables
So far I have understod that card tables are used to mark any objects from the tenured region that references to the young generation as dirty in case any references have been modified. But reading in link, and especially the figure under the section 'What pre clean did', it seems like the card table also stores young objects with references to the old generation. Is that correct? Does a card table store both way references?
