One of the best binary analysis I've read. However, I stopped after "Inserting NOP instructions".
- terminator_t600 8y agoWhy do you think Inserting NOP instructions will not work?
- anticensor 8y agoCurrent superscalar processors can skip over multiple NOPs at once.
- terminator_t600 8y agoI think it does not matter, skipping means the CPU does not execute it, but it still has room in RoB which is enough for defending Spectre. see this article: http://blog.stuffedcow.net/2013/05/measuring-rob-capacity/ http://blog.stuffedcow.net/2013/05/measuring-rob-capacity/
