@nikic Thanks very much, I've made the changes you suggested, including removing the whitelist from `matchSimpleRecurrence`. I've also added a new test to `llvm/test/Analysis/HashRecognize/cyclic-redundancy-check.ll` since with the new SCEV changes we no longer exercise the code path that the previously failing test covered.

Please let me know if you have any other suggestions or comments. :)
