Last change on this file since 110 was 110, checked in by rosiere, 15 years ago
1) OOO_egine : add stat to depiste low perf source 2) Commit : add stat 3) LSU_Pointer : retire - always ack (else combinatory loop). insert - max nb_inst_memory 4) TopLevel? : add debug_idle_time to stop combinatory loop. 5) Issue_queue : add reexecute_queue, new implementation (routage after issue_queue) 6) Decod / Predictor : add "can_continue"
