oneAPI DPC++ compiler

The DPC++ is a LLVM-based compiler project that implements compiler and runtime support for the SYCL* language. The project is hosted in the sycl branch and is synced with the tip of the LLVM upstream main branch on a regular basis (revisions delay is usually not more than 1-2 weeks). DPC++ compiler takes everything from LLVM upstream as is, however some modules of LLVM might be not included in the default project build configuration. Additional modules can be enabled by modifying build framework settings.

The DPC++ goal is to support the latest SYCL* standard and work on that is in progress. DPC++ also implements a number of extensions to the SYCL* standard, which can be found in the sycl/doc/extensions directory.

The main purpose of this project is open source collaboration on the DPC++ compiler implementation in LLVM across a variety of architectures, prototyping compiler and runtime library solutions, designing future extensions, and conducting experiments. As the implementation becomes more mature, we try to upstream as much DPC++ support to LLVM main branch as possible. See SYCL upstreaming working group notes for more details.

Note that this project can be used as a technical foundation for some proprietary compiler products, which may leverage implementations from this open source project. One of the examples is Intel(R) oneAPI DPC++ Compiler Features parity between this project and downstream projects is not guaranteed.
