Hi, I'm new to ScalarEvolution and wanted to explore its capabilities. I have following few questions: 1) How to compare SCEV expressions. I have a situation to compare two SCEV to find the min among them. Found an existing function(getMinFromExprs) in LoopAccessAnalysis which compares two SCEVs. getMinFromExprs function finds the diff between two SCEV's and then checks for the negative value to find the minimum. While checking the negative value it specifically look for SCEVConstant. Do we have anything to find the min in case of NON-SC...
