[PATCH] D127026: [CSSPGO][llvm-profgen] Reimplement computeSummaryAndThreshold using context trie

[Hongtao Yu via Phabricator via llvm-commits]

hoy added inline comments.


================
Comment at: llvm/tools/llvm-profgen/ProfileGenerator.cpp:435
-  } else {
-    // This is for the case the input is a llvm sample profile.
-    for (const auto &FS : ProfileMap) {
----------------
why delete this?


================
Comment at: llvm/tools/llvm-profgen/ProfileGenerator.cpp:1010
+  ContextTracker.createContextLessProfileMap(ContextLessProfiles);
+  ProfileGeneratorBase::computeSummaryAndThreshold(ContextLessProfiles, false);
+}
----------------
Is `false` needed here? We are passing in contextless profiles so merging them again inside `computeSummaryAndThreshold` should be fine?
