You can't ask SCEV to do this directly, but you can rewrite SCEV
expressions to substitute subexpressions in any way you like. E.g.
see SCEVInitRewriter.

ScalarEvolution questions
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
