This updates the developer policy to align with established community norms for copyright notices in source code contributed to LLVM. The updates clearly state that we do not accept code contianing explicit copyright notices in source except where such code is a pre-existing part of an external dependency that is being vendored into LLVM. Explicit copyright notices in source add no value to the project since copyright ownership is well tracked through git. Our policy already requires that contributions made not by the original author have appropriate attribution in git commit messsages or metadata. Further, explicit copyright notices in code can easily get out of date as the code is refactored, updated by additional authors or otherwise changed over time. This leads to misleading out-of-date copyright notices which do more harm than good. This change should be viewed as a clarification and statement of existing established policy, not a change in policy since it represents the way the project has been operating.
The LLVM Compiler Infrastructure
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 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, the LLD linker, and more.
