its a real prefetch and its up to you to comment out or not.Its not gonna affect correctness but performance(ie execution time). Typically Processor use WriteBuffer and store writes to WriteBuffer.From the processor point of view store is done.

I have a few questions about the prefetch for store.
we issue prefetch for store 1) when source of store is not ready && 2) we are not using WriteBuffer. The purpose is just to make sure that
store hit when issued to data$.
Does it mean that this kind of prefetch isn't a real prefetch for system, but for the implementation of simulator?
Then if I comment out the calling of the prefetch function, will it exert an influence on the correctness of the simulation? Thanks for your reply.
