2016-04-05	cpu: Add an indirect branch target predictor	Mitch Hayenga
	This patch adds a configurable indirect branch predictor that can be indexed by a combination of GHR and path history hashes. Implements the functionality described in: "Target prediction for indirect jumps" by Chang, Hao, and Patt http://dl.acm.org/citation.cfm?id=264209
2015-04-13	cpu: re-organizes the branch predictor structure.	Dibakar Gope
	Committed by: Nilay Vaish <nilay@cs.wisc.edu>
2014-06-30	cpu: implement a bi-mode branch predictor	Anthony Gutierrez

2013-05-14	cpu: remove local/globalHistoryBits params from branch pred	Anthony Gutierrez
	having separate params for the local/globalHistoryBits and the local/globalPredictorSize can lead to inconsistencies if they are not carefully set. this patch dervies the number of bits necessary to index into the local/global predictors based on their size. the value of the localHistoryTableSize for the ARM O3 CPU has been increased to 1024 from 64, which is more accurate for an A15 based on some correlation against A15 hardware.
2013-01-24	branch predictor: move out of o3 and inorder cpus	Nilay Vaish ext:(%2C%20Timothy%20Jones%20%3Ctimothy.jones%40cl.cam.ac.uk%3E)
	This patch moves the branch predictor files in the o3 and inorder directories to src/cpu/pred. This allows sharing the branch predictor across different cpu models. This patch was originally posted by Timothy Jones in July 2010 but never made it to the repository. --HG-- rename : src/cpu/o3/bpred_unit.cc => src/cpu/pred/bpred_unit.cc rename : src/cpu/o3/bpred_unit.hh => src/cpu/pred/bpred_unit.hh rename : src/cpu/o3/bpred_unit_impl.hh => src/cpu/pred/bpred_unit_impl.hh rename : src/cpu/o3/sat_counter.hh => src/cpu/pred/sat_counter.hh
