arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUUnifyDivergentExitNodes.cpp:192-193
 
-bool AMDGPUUnifyDivergentExitNodes::runOnFunction(Function &F) {
-  DominatorTree *DT = nullptr;
-  if (RequireAndPreserveDomTree)
-    DT = &getAnalysis<DominatorTreeWrapperPass>().getDomTree();
-
-  auto &PDT = getAnalysis<PostDominatorTreeWrapperPass>().getPostDomTree();
+bool AMDGPUUnifyDivergentExitNodesImpl::run(Function &F, DominatorTree *DT,
+                                            const PostDominatorTree &PDT,
+                                            const UniformityInfo &UA) {
