(Updated nov. 23, 2016, 2:52 après-midi) Review request for Default. Changes ------- Modified patch according to comments (Tournament is still default, added comments, history size). Repository: gem5 Description ------- Changeset 11707:1d085f66c4ca --------------------------- cpu: implement an L-TAGE branch predictor This patch implements an L-TAGE predictor, based on André Seznec's code available from CBP-2 (http://hpca23.cse.tamu.edu/taco/camino/cbp2/cbp-src/realistic-seznec.h). The patch also changes the default branch predictor of o3 from the tournament predictor to L-TAGE. This patch requires patch #3727 (http://reviews.gem5.org/r/3727/) to compile.
