# C++ Support in Clang

This page tracks the status of C++ support in Clang.
Currently most of the C++ features are missing; here you can find features that are at least partially supported in Clang. If you are looking to get involved with Clang development to help work on support for C++, please also look at our Open Projects page for some specific ideas.

The following table is used to help track our implementation progress toward implementing the complete C++03 standard. We use a simple, somewhat arbitrary color-coding scheme to describe the relative completeness of features by section:

Not started/not evaluated | Not Applicable | Broken | Some examples work | Many examples work | Nearly everything works | Complete!
--- | --- | --- | --- | --- | --- | ---
| N/A |  |  |  |  | ✓

A feature is "complete" when the appropriate Clang component (Parse, AST, Sema, CodeGen) implements the behavior described in all of the paragraphs in the relevant C++ standard. Note that many C++ features are actually described in several different sections within the standard. The major components are:

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! Since Clang already supports much of C, and therefore much C++, many of the currently-white cells could be filled in. If you wish to do so, please compare Clang's implementation against the C++ standard and provide a patch that updates the table accordingly. Tests for the various features are also welcome!
