================
Comment at: clang-tools-extra/clang-tidy/llvm/PreferRegisterOverUnsignedCheck.cpp:40
+
+  diag(UserVarDecl->getLocation(), "var %0 is %1 but holds a register")
+      << UserVarDecl << *VarType;
----------------
How about `variable %0 declared as %1; use '%2' instead` and move it below to where the fix-it is issued?


================
Comment at: clang-tools-extra/clang-tidy/llvm/PreferRegisterOverUnsignedCheck.cpp:44
+  const DeclContext *Context = UserVarDecl->getDeclContext();
+  while((Context = Context->getParent()) != nullptr) {
+    if (const auto *Namespace = dyn_cast<NamespaceDecl>(Context))
----------------
Formatting looks off here, you should run the patch through clang-format.


================
Comment at: clang-tools-extra/clang-tidy/llvm/PreferRegisterOverUnsignedCheck.cpp:53
+  }
+  diag(UserVarDecl->getLocation(), "use '%0'", DiagnosticIDs::Note)
+      << Replacement
----------------
I don't think you should issue a second diagnostic on the same line. Instead, only issue the previous diagnostic with the fixit attached to it.
