...ysis phase -basicaa increases the runtime back to 3.1 seconds or above. When I was explaining this strange behaviour in the HiPEAC conference some one asked me how can dropping an analysis phase will have an impact on the program runtime. Can some one explain what is happening here? The program is office_stringsearch1 from the MiBench suite. On the same lines the way we hit upon the sequence [-functionattrs, -loop-rotate, -licm, -basicaa] is by applying a sequence reduction algorithm wherein we take a long sequence (which we hit using genetic or random search algorithm) and keep dropping the optimizations un...
