%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.

# We tried in the past to split the cmake exports for these binaries out into
