================
Comment at: llvm/lib/CodeGen/CallBrPrepare.cpp:64
 void CallBrPrepare::getAnalysisUsage(AnalysisUsage &AU) const {
-  AU.setPreservesAll();
+  AU.addPreserved<DominatorTreeWrapperPass>();
 }
----------------
@aeubanks does this delta look correct?


================
Comment at: llvm/lib/CodeGen/CallBrPrepare.cpp:128-129
+
+  auto *DTWP = getAnalysisIfAvailable<DominatorTreeWrapperPass>();
+  DominatorTree *DT = DTWP ? &DTWP->getDomTree() : nullptr;
+
----------------
@aeubanks does this look correct?
