[PATCH] D121006: Speedup dsymutil when working with big project.

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added inline comments.


================
Comment at: llvm/tools/dsymutil/MachODebugMapParser.cpp:58
+  /// `getMainBinarySymbolNames`;
+  std::unordered_map<uint64_t, std::vector<StringRef>>
+      MainBinaryAddresses2NamesMap;
----------------
`std::unordered_map` has bad performance characteristics.
Does it help if this is instead a SmallDenseMap of SmallVector's?
