Clang provides support for a number of features included in the new ISO C++ Standard, ISO/IEC 14882:2011. The following table describes which C++11 features have been implemented in Clang and in which Clang versions they became available.

By default, Clang builds C++ code according to the C++98 standard, with many
+C++11 features accepted as extensions. You can use Clang in C++11 mode with the
+-std=c++11 option. Clang's C++11 mode can be used
+with libc++ or with gcc's libstdc++, but
+patches are needed to make libstdc++-4.4
work with Clang in C++11 mode. Patches are also needed to make
libstdc++-4.6,
and libstdc++-4.7 work with Clang
