Comment at: llvm/lib/DebugInfo/PDB/Native/NamedStreamMap.cpp:35
+    // HASH Hasher<ULONG*, USHORT*>::hashPbCb(PB pb, size_t cb, ULONG ulMod).
+    // Here, the type HASH is a typedef of unsigned short.
+    // ** It is not a bug that we truncate the result of hashStringV1, in fact

It's `uint16_t` in my code, but it's only correct if it's also uint16 in the reference implementation.  But the signature in the reference implementation uses the type `HASH` for the return value, and it can be easily overlooked that that type is in fact also a uint16.  That was the purpose of the comment here.
