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

|

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