clang
- Ebuilds: 13, Stable: 21.1.8, Testing: 22.1.2 Description: The goal of the Clang project is to create a new C, C++, Objective C and Objective C++ front-end for the LLVM compiler.
Features and Goals
Some of the goals for the project include the following:
End-User Features:
Fast compiles and low memory use
Expressive diagnostics
GCC compatibility
Utility and Applications:
Modular library based architecture
Support diverse clients (refactoring, static analysis, code generation, etc)
Allow tight integration with IDEs
Use the LLVM BSD License
Internal Design and Implementation:
A real-world, production quality compiler
A simple and hackable code base
A single unified parser for C, Objective C, C++, and Objective C++
Conformance with C/C++/ObjC and their variants

llvm
- Ebuilds: 13, Stable: 21.1.8, Testing: 22.1.2 Description: Low Level Virtual Machine (LLVM) is:
1. A compilation strategy designed to enable effective program optimization across the entire lifetime of a program. LLVM supports effective optimization at compile time, link-time (particularly interprocedural), run-time and offline (i.e., after software is installed), while remaining transparent to developers and maintaining compatibility with existing build scripts.
2. A virtual instruction set - LLVM is a low-level object code representation that uses simple RISC-like instructions, but provides rich, language-independent, type information and dataflow (SSA) information about operands. This combination enables sophisticated transformations on object code, while remaining light-weight enough to be attached to the executable. This combination is key to allowing link-time, run-time, and offline transformations.
3. A compiler infrastructure - LLVM is also a collection of source code that implements the language and compilation strategy. The primary components of the LLVM infrastructure are a GCC-based C and C++ front-end, a link-time optimization framework with a growing set of global and interprocedural analyses and transformations, static back-ends for many popular (and some obscure) architectures, a back-end which emits portable C code, and a Just-In-Time compilers for several architectures.
4. LLVM does not imply things that you would expect from a high-level virtual machine. It does not require garbage collection or run-time code generation (In fact, LLVM makes a great static compiler!). Note that optional LLVM components can be used to build high-level virtual machines and other systems that need these services.
