[PATCH] D89847: [SCEV] Drop cached ranges of AddRecs after flag update

[Max Kazantsev via Phabricator via llvm-commits]

mkazantsev added inline comments.


================
Comment at: llvm/lib/Analysis/ScalarEvolution.cpp:5520
+  if (AddRec->getNoWrapFlags(Flags) != Flags) {
+    assert(AddRec->getNoWrapFlags(Flags) <= Flags && "Pessimizing AddRec flags?");
+    AddRec->setNoWrapFlags(Flags);
----------------
I realized it's not the right way to check it since the assert may never fail.
