Hoist handling of Doxygen into the top-level cmake/ directory so it can be shared between LLVM and RUNTIMES and a default/standalone runtimes build can support building Doxygen documentation as well. The openmp subproject currently supports doxygen documentation using an `LLVM_ENABLE_PROJECTS=openmp` build, but not with `LLVM_ENABLE_RUNTIMES=openmp` because of this missing boilerplate code in the runtimes build. This is a step towards removing the `LLVM_ENABLE_PROJECTS=openmp` build mode which was deprecated (#124014) and already scheduled to be removed in LLVM 21 (#136314). Eventual removal is planned with #176950. Hoisting CMake code for shared use with runtimes has been done before in e.g. #84641, 7017e6c9cfd2de3122ce9528f338a97d61e96373, 44e3365775101fec3fd355eda339282258d74415, 7017e6c9cfd2de3122ce9528f338a97d61e96373 --------- Co-authored-by: Petr Hosek <phosek@google.com>
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.
