Last change on this file since 108 was 108, checked in by rosiere, 15 years ago
1) decod_queue : add reg_LAST_SLOT. 2) Commit : insert on event -> to pop decod_queue. Head test : add information (speculative or not) 3) Context State / UPT : Branch miss and Load miss in same cycle. 4) Free List : Bank is on LSB not MSB. 5) Platforms : move data
