Clang provides support for a number of features included in the new ISO C++ Standard, ISO/IEC 14882:2011. This section tracks the status of various C++11 features, and a number of other C++11 features are under active development.

The following table is used to help track our implementation - progress toward implementing the complete C++'11 standard. We use a - simple, somewhat arbitrary color-coding scheme to describe the - relative completeness of features:

Parse
-
Clang is able to parse the grammar of this feature (or the grammar - described by this section), but does not necessarily do anything with the - parsed result. Use Clang's -fsyntax-only option to parse C++ - programs.
- -
AST
-
Clang builds an abstract syntax tree (AST) for the feature, but does not - necessarily perform any type-checking. Use Clang's -ast-print - option to print the resulting ASTs.
- -
Sema
-
Clang parses and type-checks this feature and provides a well-formed AST - annotated with types. Use Clang's -fsyntax-only to type-check - code.
- -
CodeGen
-
Clang parses, type-checks, and generates code for this feature, allowing - one to compile and execute programs.

Updates to this table are welcome! Tests for the various features are also -welcome!
