%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 build of LLVM is patched to produce assembly code for Ducky VM.
