Review request for Default. Description ------- This patch adds a global-global (gAG) branch predictor, used by specifying the "global" predType. >From BranchPredictor, it uses the following variables for configuration: - globalPredictorSize - globalCtrBits - globalHistoryBits As such, it may conflict with the ongoing effort to factor out the redundant variable in the predictors. Diffs ----- src/cpu/pred/SConscript 00dca8a9b560 src/cpu/pred/bpred_unit.cc 00dca8a9b560 src/cpu/pred/global.hh PRE-CREATION src/cpu/pred/global.cc PRE-CREATION Diff: http://reviews.gem5.org/r/1865/diff/ Testing ------- Prior to submission, this was tested by building build/ARM/gem5.debug, and run against a subset of the SPEC CPU2006 benchmarks. Statistics generated seem valid, and it caused no execution errors.
