The ITTAGE indirect branch predictor
Modern CPUs are actually pretty good at predicting the indirect branch inside an interpreter loop, _contra_ the conventional wisdom. We take a deep dive into the ITTAGE indirect branch prediction algorithm, which is capable of making those predictions, and draw some connections to some other interests of mine in the areas of fuzzing and reinforcement learning.
