I am trying to understand the code in memnode.hpp

What is the meaning of the nodes Control, Memory and Address that a MemNode has? I understand more or less that a MemNode defines a memory reference, Memory defines the base and Address defines the offset. But the meaning of Control is still unclear to me (a comment describes it as "// When is it safe to do this load?"). -------------- next part -------------- An HTML attachment was scrubbed...
