[PATCH] D127031: [CSSPGO][llvm-profgen] Reimplement SampleContextTracker using context trie

[Hongtao Yu via Phabricator via llvm-commits]

hoy added inline comments.


================
Comment at: llvm/include/llvm/Transforms/IPO/SampleContextTracker.h:185
+  // FunctionSamples points to.
+  std::unordered_map<ContextTrieNode *, std::unordered_set<FunctionSamples *>>
+      Node2FSamplesSetMap;
----------------
Actually my previous question could be made more clear as why we need to maintain this map.
