extra template parameter, even if it had a default value. The

Selected when GCC supports a builtin atomic compare-and-swap operation
on the target processor (see <a class="link" href="http://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html" target="_top">Atomic
algorithm and GCC's atomic builtins, which provide the required memory
synchronisation.
</p></li><li class="listitem"><p>
- <code class="constant">_S_Mutex</code>
+ <code class="constant">_S_mutex</code>
</p><p>
The _Sp_counted_base specialization for this policy contains a mutex,
which is locked in add_ref_lock(). This policy is used when GCC's atomic
builtins aren't available so explicit memory barriers are needed in places.
</p></li><li class="listitem"><p>
- <code class="constant">_S_Single</code>
+ <code class="constant">_S_single</code>
</p><p>
This policy uses a non-reentrant add_ref_lock() with no locking. It is
used when libstdc++ is built without <code class="literal">--enable-threads</code>.

This section describes the C++17 and library TS support in the GCC 7 series.
