| Description: | Low-Level Virtual Machine (LLVM), C language family frontend The Low-Level Virtual Machine (LLVM) is a collection of libraries and tools that make it easy to build compilers, optimizers, Just-In-Time code generators, and many other compiler-related programs. LLVM uses a single, language-independent virtual instruction set both as an offline code representation (to communicate code between compiler phases and to run-time systems) and as the compiler internal representation (to analyze and transform programs). This persistent code representation allows a common set of sophisticated compiler techniques to be applied at compile-time, link-time, install-time, run-time, or "idle-time" (between program runs). . Clang project is a C, C++, Objective C and Objective C++ front-end for the LLVM compiler. Some of its goals include the following: . End-User Features: . * Fast compiles and low memory use * Expressive diagnostics (examples) * 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 Homepage: http://www.llvm.org/ |
