55 * Implements a local predictor that uses the PC to index into a table of
56 * counters. Note that any time a pointer to the bp_history is given, it
57 * should be NULL using this predictor because it does not have any branch
58 * predictor state that needs to be recorded or updated; the update can be
59 * determined solely by the branch being taken or not taken.
