The tombstone is simply a key value that 1. cannot occur as a key in the map (inserting EmptyKey or TombstoneKey will trigger an assertion) 2. does not compare equal to any other value We usually use something like...

...defined typedef ScopedHashTable<DoubleKey, std::pair<Value *, unsigned>, DenseMapInfo<Value *>, LoadMapAllocator> LoadHTType; I declared a DoubleKey struct similar to CallValue but with two Value * member, However I have problem to implement getTombstoneKey() because I don't know what it is, could anyone tell me what it is about? -------------- next part -------------- An HTML attachment was scrubbed...
