The DPC++ Compiler compiles C++ and SYCL source files with code for both CPU and a wide range of compute accelerators such as GPU and FPGA. This article describes the availability and version of DPC++ Compiler where support for the SYCL 2020 specification features or DPC++ language extensions was added.
SYCL 2020 Support
Starting from 2024.1, we are officially conformant with SYCL 2020 and supporting all SYCL 2020 APIs. Please refer to https://github.com/intel/llvm/tree/sycl/sycl/doc/extensions for detailed extension enabling status.
DPC++ Extensions
