+
+modernize-use-equals-default
+============================
+
+This check replaces default bodies of special member functions with ``=
+default;``. The explicitly defaulted function declarations enable more
+opportunities in optimization, because the compiler might treat explicitly
+defaulted functions as trivial.
+
+.. code-block:: c++
+
+  struct A {
+    A() {}
+    ~A();
+  };
+  A::~A() {}
+
+  // becomes
+
+  struct A {
+    A() = default;
+    ~A();
+  };
+  A::~A() = default;
+
+.. note::
+  Move-constructor and move-assignment operator are not supported yet.
+
+Options
+-------
+
+.. option:: IgnoreMacros
+
+   If set to non-zero, the check will not give warnings inside macros. Default
+   is `1`.
