Last change on this file since 111 was 111, checked in by rosiere, 15 years ago
1) Decod_queue : multi implementation (one_fifo, multi_fifo) 2) Issue_queue : multi implementation (in_order, out_of_order) 3) Direction : Add Meta predictor 4) Context_State : re add Branch_complete, More priority to Load miss (is not speculative) 5) Return_Address_Stack : update reg_PREDICT pointer on decod miss prediction 6) UPT : Fix bug in multi event 7) Prediction_glue : in read_stack case, insert in UPT pc_next 8) Rename select : when rob have an event (need flush), read_r{a,b,c} and write_r{d,e} is set at 0
