For instance, GCC uses a step called fold that is key to the overall compile process, which has the side effect of translating the code tree into a form that looks unlike the original source code. In contrast, GCC works in a compile- link- debug workflow integrating it with other tools is not always easy. One of Clang's main goals is to provide a library-based architecture, so that the compiler could interoperate with other tools that interact with source code, such as integrated development environments (IDE). The combination of Clang and LLVM provides most of the toolchain for replacing the GCC stack. In July 2007, the project received the approval for becoming open-source. In the end, Apple chose to develop Clang, a new compiler front end that supports C, Objective-C and C++.

Finally, GCC's license agreement, the GNU General Public License (GPL) version 3, requires developers who distribute extensions or modified versions of GCC to make their source code available, but LLVM's permissive software license is devoid of such impediment.
As such, GCC does not integrate smoothly into Apple's integrated development environment (IDE). Besides, Apple software uses Objective-C, which is a low priority for GCC developers. The GCC source code, however, is large and somewhat cumbersome as one long-time GCC developer put it referring to LLVM, "Trying to make the hippo dance is not really a lot of fun". The LLVM project originally intended to use GCC's front end. This allowed Apple to support OpenGL on computers using Intel GMA chipsets, increasing performance on those machines. One of the first uses of LLVM was an OpenGL code compiler for OS X that converts OpenGL calls into more fundamental calls for graphics processing units (GPU) that do not support certain features. began extensive use of LLVM in several commercial products, including the iOS SDK and Xcode 3.1. Since v6.0.0, Clang compiles C++ using the GNU++14 dialect by default, which includes features from the C++14 standard and conforming GNU extensions.

Its contributors include Apple, Microsoft, Google, ARM, Sony, Intel, and AMD.Ĭlang 14, the latest major version of Clang as of March 2022, has full support for all published C++ standards up to C++17, implements most features of C++20, and has initial support for the upcoming C++23 standard. As with LLVM, it is free and open-source software under the Apache License 2.0 software license. Ĭlang operates in tandem with the LLVM compiler back end and has been a subproject of LLVM 2.6 and later. It includes a static analyzer, and several code analysis tools. It acts as a drop-in replacement for the GNU Compiler Collection (GCC), supporting most of its compilation flags and unofficial language extensions. AArch64, ARMv7, IA-32, x86-64, ppc64le Īpache License 2.0 with LLVM Exceptions Ĭlang is a compiler front end for the C, C++, Objective-C, and Objective-C++ programming languages, as well as the OpenMP, OpenCL, RenderScript, CUDA, and HIP frameworks.
