Comment at: clang-tools-extra/clangd/index/MemIndex.cpp:95
     LookupRequest LookupReq;
-    auto It = Relations.find(std::make_pair(Subject, Req.Predicate));
+    auto It = Relations.find(std::make_pair(Subject, (uint8_t)Req.Predicate));
     if (It != Relations.end()) {
----------------
`static_cast<>`


================
Comment at: clang-tools-extra/clangd/index/MemIndex.h:75
+  static_assert(sizeof(RelationKind) == sizeof(uint8_t),
+                "use a mismatch type of RelationKind");
+  llvm::DenseMap<std::pair<SymbolID, uint8_t>, std::vector<SymbolID>> Relations;
----------------
"RelationKind should be of same size as a uint8_t"


================
Comment at: llvm/include/llvm/ADT/DenseMapInfo.h:70
 
+// Provide DenseMapInfo for unsign chars.
+template <> struct DenseMapInfo<unsigned char> {

+  static inline unsigned char getTombstoneKey() { return ~0 - 1; }
+  static unsigned getHashValue(const char &Val) { return Val * 37U; }
