Hi Hashim, Scalar evolution determines evolution of scalar in terms of expression chain driving it. Try dumping the detailed log using opt -analyze -scalar-evolution <.ll> -S , and look for LoopDispositions corresponding to different expression which shows variance characteristics of a particular expression w.r.t loop i.e. [computable/variant/invariant].

Hi, I am using Scalar Evolution to extract access expressions (for load and store instructions) in terms of the loop induction variables. I observe that the Scalar Evolution analysis is returning more expressions than I expect - including ones that are not defined in terms of the loop induction variable. For instance in the following code: for(unsigned long int bid = 0; bid < no_of_queries;
