INSTRUCTION AND LOGIC TO EFFICIENTLY MONITOR LOOP TRIP COUNT

摘要

Logic and instruction to efficiently monitor loop trip count. Loop trip count information of a loop may be stored in a dedicated hardware buffer. Average loop trip count of the loop may be calculated based on the stored loop trip count information. Based on the average trip count, loop optimizations may be applied or removed from the loop. The stored loop trip count information may include an identifier identifying the loop, a total loop trip count of the loop, and an exit count of the loop.
