Status of Experimental C++11 Support in GCC 4.8

GCC provides experimental support for the 2011 ISO C++ standard. This support can be enabled with the -std=c++11 or -std=gnu++11 compiler options; the former disables GNU extensions.

As of GCC 4.8.1, GCC's C++11 mode implements all of the major features of the C++11 standard produced by the ISO C++ committee. The standard is available from various national standards bodies; working papers from before the release of the standard are available on the ISO C++ committee's web site at https://www.open-std.org/jtc1/sc22/wg21/. Since this standard has only recently been completed, the feature set provided by the experimental C++11 mode may vary greatly from one GCC version to another. No attempts will be made to preserve backward compatibility with C++11 features whose semantics have changed during the course of C++11 standardization.

The following table lists which C++11 features are supported in this release of GCC. For more information about C++11 support in GCC, please see the C++11 in GCC project page.
