clang: noun
1. A loud, resonant, metallic sound.
2. The strident call of a crane or goose.
3. C-language family front-end toolkit.
The goal of the Clang project is to create a new C, C++, Objective C
and Objective C++ front-end for the LLVM compiler. Its tools are built
as libraries and designed to be loosely-coupled and extensible.
Install compiler-rt if you want the Blocks C language extension or to
enable sanitization and profiling options when building, and
libomp-devel to enable -fopenmp.
