%description
LLVM is a compiler infrastructure designed for compile-time, link-time,
runtime, and idle-time optimization of programs from arbitrary programming
languages.

The LLVM compiler infrastructure supports a wide range of projects,
from industrial strength compilers to specialized JIT applications
to small research projects.
