llvm/test/Transforms/IndVarSimplify
History
David Green a33c5722b0 [IndVarSimplify] Add AShr exact flags using induction variables ranges. 
This adds exact flags to AShr/LShr flags where we can statically
prove it is valid using the range of induction variables. This
allows further optimisations to remove extra loads.
