Clang is the C language family front-end for the LLVM compiler. (The C language family includes C, C++, Objective-C, and Objective-C++.)

Clang refers to the C language family front-end for the LLVM (originally known as "low level virtual machine") compiler. The C language family consists of C, C++, Objective-C, and Objective-C++.

High-level features of clang include better compile-time performance than gcc, helpful error and warning messages, and a static analyzer to automatically detect software bugs.
