================ Comment at: clang/lib/ASTMatchers/ASTMatchFinder.cpp:902 // Maps (matcher, node) -> the match result for memoization. - typedef std::map<MatchKey, MemoizedMatchResult> MemoizationMap; + typedef std::map<MatchKey, MemoizedMatchResult, std::less<>> MemoizationMap; MemoizationMap ResultCache; ---------------- klimek wrote: > Ok, if this actually matters, we should also not use a std::map here, but a > llvm::DenseMap (or do we rely on iteration invalidation semantics here?). Belated +1. 5% seems like this performance *does* matter, so DenseMap::find_as should be yet faster. It looks like BoundNodesTreeBuilder would need a DenseMapInfo, but all the other members are hashable already.
