The caching is switched to always use a BB to +cache entry map, which then contains per-value caches. A separate +set contains value handles with a deletion callback. This allows us +to properly invalidate overdefined values. + +A possible alternative would be to always cache by value first and +have per-BB maps/sets in the each cache entry. In that case we could +use a ValueMap and would avoid the separate value handle set. I went +with the BB indexing at the top level to make it easier to integrate +D69914, but possibly that's not the right choice. + +Differential Revision: https://reviews.llvm.org/D70376 + +diff --git a/llvm/lib/Analysis/LazyValueInfo.cpp b/llvm/lib/Analysis/LazyValueInfo.cpp +index 110c085d3f3..aa6862cb588 100644 +--- a/llvm/lib/Analysis/LazyValueInfo.cpp ++++ b/llvm/lib/Analysis/LazyValueInfo.cpp +@@ -133,12 +133,9 @@ namespace { + /// A callback value handle updates the cache when values are erased. + class LazyValueInfoCache; + struct LVIValueHandle final : public CallbackVH { +- // Needs to access getValPtr(), which is protected. +- friend struct DenseMapInfo<LVIValueHandle>; +- + LazyValueInfoCache *Parent; + +- LVIValueHandle(Value *V, LazyValueInfoCache *P) ++ LVIValueHandle(Value *V, LazyValueInfoCache *P = nullptr) + : CallbackVH(V), Parent(P) { } + + void deleted() override; +@@ -152,89 +149,63 @@ namespace { + /// This is the cache kept by LazyValueInfo which + /// maintains information about queries across the clients' queries. + class LazyValueInfoCache { +- /// This is all of the cached block information for exactly one Value*. +- /// The entries are sorted by the BasicBlock* of the +- /// entries, allowing us to do a lookup with a binary search. +- /// Over-defined lattice values are recorded in OverDefinedCache to reduce +- /// memory overhead. +- struct ValueCacheEntryTy { +- ValueCacheEntryTy(Value *V, LazyValueInfoCache *P) : Handle(V, P) {} +- LVIValueHandle Handle; +- SmallDenseMap<PoisoningVH<BasicBlock>, ValueLatticeElement, 4> BlockVals; ++ /// This is all of the cached information for one basic block.
