LGTM with a minor suggestion to not call `getLocStart()` twice and a formatting fix. I think you should also ping @hans to get this pulled into the 6.0 branch once it's been commit.



================
Comment at: clang-tidy/fuchsia/OverloadedOperatorCheck.cpp:33-37
+  if (const auto *D = Result.Nodes.getNodeAs<FunctionDecl>("decl")) {
+    if (D->getLocStart().isValid())
+      diag(D->getLocStart(), "cannot overload %0") << D;
+  }
 }
----------------
I think this code can be simplified to:
```
const auto *D = Result.Nodes...
assert(D && "No FunctionDecl captured!");

SourceLocation Loc = D->getLocStart();
if (Loc.isValid())
  diag(Loc, ...);
```


================
Comment at: test/clang-tidy/fuchsia-overloaded-operator.cpp:20
+
+void operator delete (void*, void*) throw();
+// CHECK-MESSAGES: [[@LINE-1]]:1: warning: cannot overload 'operator delete' [fuchsia-overloaded-operator]
----------------
Formatting is off -- this should be `operator delete(`... (no space after "delete").
