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