%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.

%if %{?_with_gcc:1}%{!?_with_gcc:0}
It currently supports compilation of C and C++ programs, using front
ends derived from GCC %{lgcc_version}.
