Clang (/ˈklæŋ/)[6] is a compiler front end for the C, C++, Objective-C, and Objective-C++ programming languages, as well as the OpenMP,[7] OpenCL, RenderScript, CUDA, SYCL, and HIP[8] frameworks. It acts as a drop-in replacement for the GNU Compiler Collection (GCC), supporting most of its compilation flags and unofficial language extensions.[9][10] It includes a static analyzer, and several code analysis tools.[11]
Clang operates in tandem with the LLVM compiler back end and has been a subproject of LLVM 2.6 and later.[12] As with LLVM, it is free and open-source software under the Apache License 2.0 software license.[4][5] Its contributors include Apple, Microsoft, Google, ARM, Sony, Intel, and AMD.
Clang 17, the latest major version of Clang as of October 2023, has full support for all published C++ standards up to C++17, implements most features of C++20, and has initial support for the upcoming C++23 standard.[13] Since v16.0.0, Clang compiles C++ using the GNU++17 dialect by default, which includes features from the C++17 standard and conforming GNU extensions.[14]

Clang is a subproject of the LLVM Project, but has its own mailing lists because the communities have people with different interests.
