H A D | abstract_mem.hh | diff 13853:7ec6a25d2bc1 Mon Mar 25 21:04:00 EDT 2019 Gabe Black <gabeblack@google.com> mem: Maintain a back door into the AbstractMem's backing store. The backing store pointer is added to the back door when it's set, assuming that the range isn't interleaved. If it is interleaved, then there isn't a way to get a flat pointer to the backing store. Depending on how the backing store is set up, it may be possible to return a larger backdoor which applies to all interleaved memories at the same time and to avoid problems with interleaving. I'm leaving this as a todo.
