cpu/o3/2bit_local_pred.cc:
Branch predictor cleanup/fixup. Rename this to LocalBP.
cpu/o3/2bit_local_pred.hh:
Rename to LocalBP, update to support changes to BPredUnit, include comments.
cpu/o3/alpha_cpu_builder.cc:
Support extra parameters to the branch predictor. Now it takes in a parameter to tell it which branch predictor it is using, the local or the tournament predictor.
cpu/o3/alpha_params.hh:
Add in extra parameter for the branch predictor type.
cpu/o3/bpred_unit.cc:
Branch predictor fixup/cleanup. Rename it to BPredUnit.
cpu/o3/bpred_unit.hh:
Branch predictor fixup/cleanup. Now supports both the local and tournament predictors, and stores the branch predictor update state.
cpu/o3/bpred_unit_impl.hh:
Branch predictor overhaul. Now supports both the local and tournament predictors.
cpu/o3/cpu_policy.hh:
cpu/ozone/ozone_impl.hh:
cpu/ozone/simple_impl.hh:
Reflect the class name change.
cpu/o3/decode_impl.hh:
Be sure to set the predicted target as well so we don't squash twice.
cpu/o3/tournament_pred.cc:
cpu/o3/tournament_pred.hh:
Fixes to the tournament predictor.
cpu/ozone/simple_params.hh:
Include parameter for the branch predictor type.
python/m5/objects/AlphaFullCPU.py:
python/m5/objects/OzoneCPU.py:
Include the parameter for the branch predictor type.
