================
Comment at: llvm/lib/Transforms/Scalar/LoopRotation.cpp:97
     auto *AC = &getAnalysis<AssumptionCacheTracker>().getAssumptionCache(F);
     auto *DTWP = getAnalysisIfAvailable<DominatorTreeWrapperPass>();
     auto *DT = DTWP ? &DTWP->getDomTree() : nullptr;
----------------
AFAICT this also holds true for the DominatorTreeWrapperPass.
