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