41 The <application>LLVM</application> package contains a collection of modular and
42 reusable compiler and toolchain technologies. The Low Level Virtual Machine
43 (LLVM) Core libraries provide a modern source and target-independent optimizer,
44 along with code generation support for many popular CPUs (as well as some less
45 common ones!). These libraries are built around a well specified code
46 representation known as the LLVM intermediate representation ("LLVM IR").
