The Clang project provides a language front-end and tooling
|

infrastructure for languages in the C language family (C, C++, Objective
|
||||
C/C++, OpenCL, CUDA, and RenderScript) for the LLVM project.
|
||||
It aims to deliver amazingly fast compiles, extremely useful error and
|
||||
warning messages and to provide a platform for building great source
|
||||
level tools. The Clang Static Analyzer and clang-tidy are tools that
|
||||
automatically find bugs in your code, and are great examples of the sort
|
||||
of tools that can be built using the Clang frontend as a library to
|

parse C/C++ code.
