+Non-temporal load/store builtins
+--------------------------------
+
+Clang provides overloaded builtins allowing generation of non-temporal memory
+accesses.
+
+.. code-block:: c
+
+ T __builtin_nontemporal_load(T *addr);
+ void __builtin_nontemporal_store(T value, T *addr);
+
+The types ``T`` currently supported are:
+
+* Integer types.
+* Floating-point types.
+* Vector types.
+
+Note that the compiler does not guarantee that non-temporal loads or stores
+will be used.
