Correct Alignment of a Return-Address-Stack after Call and Return Mispredictions.pdf
- It is accepted that the alignment of a return-address- stack can be preserved by checkpointing on branches and recovering on branch mispredictions the top-of- stack pointer. However, virtually all published litera- ture, is vague or proposes sub-optimal algorithms on how to repair the alignment of a return-address-stack on call and return mispredictions. Possible manifesta- tions of this ambiguity are lower performing implemen- tations of return-address-stack mechanisms in proces- sors and simulators. This paper suggests that on call and return mispredictions the recovered top-of-stack pointer should point to the next and previous stack po- sition respectively relative to the checkpointed top-of- stack pointer. It is established experimentally that the proposed method can improve the performance, over an other- wise identical processor conguration, on the average by 2% and by as much as 10%. This corresponds to a drop in return-address mispredictions by 40%, from 11.3% downto 6.7%
