Body
click here to access the chatroom for this question. I would like to swap two variables. and i would like to do it through the pipeline using a Read After Write hazard to my advantage. Pipeline: OPERXXXXXX FetchXXXXX DecodeXXXX ExecuteXXX WriteBkXXX STORE X, Y ---------- ---------- ---------- ---------- STORE Y, X STORE X, Y ---------- ---------- ---------- ---------- STORE Y, X STORE X, Y ---------- ---------- ---------- ---------- STORE Y, X STORE X, Y ---------- ---------- ---------- ---------- STORE Y, X STORE X, Y ---------- ---------- ---------- ---------- STORE Y, X how do i go about telling the compiler to do that (and exactly that) without automatic locks and warning flags? can you suggest any literature/keywords? specs: -> target: modern architectures which support multistation (more than 4) pipelining -> this is not related to any particular 'problem'. just for the sake of science. current hurdles: if you know how to ignore datahazards, please share.
