| Welcome to the LLVM project! | |
| This repository contains the source code for LLVM, a toolkit for the | |
| construction of highly optimized compilers, optimizers, and run-time | |
| environments. | |
| The LLVM project has multiple components. The core of the project is | |
| itself called "LLVM". This contains all of the tools, libraries, and header | |
| files needed to process intermediate representations and convert them into | |
| object files. Tools include an assembler, disassembler, bitcode analyzer, and | |
| bitcode optimizer. | |
| C-like languages use the [Clang](https://clang.llvm.org/) frontend. This | |
| component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode | |
| -- and from there into object files, using LLVM. | |
| Other components include: | |
| the [libc++ C++ standard library](https://libcxx.llvm.org), | |
| the [LLD linker](https://lld.llvm.org), and more. | |
| ## Getting the Source Code and Building LLVM | |
