%description
LLVM is a compiler infrastructure designed for compile-time, link-time,
runtime, and idle-time optimization of programs from arbitrary programming
languages. The compiler infrastructure includes mirror sets of programming
tools as well as libraries with equivalent functionality.

This package contains LLVM %{major_version} and can be installed
in parallel with other LLVM versions.
