5 This repository contains the source code for LLVM, a toolkit for the
|
|
|
6 construction of highly optimized compilers, optimizers, and run-time
|
|
|
7 environments.

9 The LLVM project has multiple components. The core of the project is
|
|
|
10 itself called "LLVM". This contains all of the tools, libraries, and header
|
|
207
|
11 files needed to process intermediate representations and convert them into
|
|
236
|
12 object files. Tools include an assembler, disassembler, bitcode analyzer, and
|
|
252
|
13 bitcode optimizer.
|

|
15 C-like languages use the [Clang](http://clang.llvm.org/) frontend. This
|
|
173
|
16 component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode
|
|
150
|
17 -- and from there into object files, using LLVM.
|
|
|
18
|
|
|
19 Other components include:
|
|
|
20 the [libc++ C++ standard library](https://libcxx.llvm.org),
|
|
|
21 the [LLD linker](https://lld.llvm.org), and more.
