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

52 The optional <application>Clang</application> and <application>Compiler
53 RT</application> packages provide a new C, C++, Objective C and Objective
54 C++ front-ends and runtime libraries for the
55 <application>LLVM</application>.

60 This package hits a bug in GCC-4.9.0 or an unpatched GCC-4.9.1.
61 To build this package, GCC needs to be updated if you have one of
62 these versions. See <xref linkend="gcc"/>
63 for <application>gcc</application> installation instructions.
