Dependencies included in the release

Components included in the release

  • clang version 19.0.0
  • SYCL runtime version 8.0.0 (as indicated by predefined macro
    __LIBSYCL_MAJOR_VERSION, __LIBSYCL_MINOR_VERSION and
    __LIBSYCL_PATCH_VERSION)

Compatibility with previous releases

This is a first formal release in this repo and therefore there are no other
releases to be compatible with.

However, the repo has existed for a while and this release is not compatible
with builds produced from older commits, because there were ABI-breaking changes
made to the codebase just prior taking the sycl-rel-6_0_0 branch.

Compatibility with oneAPI

Intel(R) oneAPI DPC++/C++ Compiler
version 2025.0 leverages codebase from sycl-rel-6_0_0 branch and it is the
closest oneAPI DPC++/C++ compiler release to this one (in terms of available
features and bugfixes).

However, this does not guarantee any feature or bugfix parity between
these two releases.

Validation & quality expectations

In general, list of supported hardware and operating systems should match the
one provided by Intel(R) oneAPI DPC++/C++ Compiler for version 2025.0, see
corresponding system requirements.

However, we did not perform the same exaustive testing of this open-source
branch and therefore there could be some unique issues that are not present in
Intel (R) oneAPI DPC++/C++ Compiler version 2025.0.

You can find full validation logs for the branch
here
but a summary of it will also be posted below.

End to end tests

The following hardware and software configurations were tested:

Driver versions listed as reported by
sycl::device::get_info<info::device::driver_version>().

  • Windows
    • Driver version: 32.0.101.6129
    • Intel(R) oneAPI Unified Runtime over Level-Zero on
      Intel(R) Iris(R) Xe Graphics 12.0.0
    • Intel(R) OpenCL Graphics on Intel(R) Iris(R) Xe Graphics OpenCL 3.0 NEO
  • Linux (Ubuntu 22.04)
    • Intel(R) OpenCL Graphics on Intel(R) Iris(R) Xe Graphics OpenCL 3.0 NEO
    • Intel(R) oneAPI Unified Runtime over Level-Zero on
      Intel(R) Iris(R) Xe Graphics 12.0.0
    • Intel(R) OpenCL on
      11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80 Ghz OpenCL 3.0
    • AMD HIP BACKEND on AMD Radeon RX 6700 XT gfx1031
    • NVIDIA CUDA BACKEND on NVIDIA A10G 8.6

SYCL CTS

  • Linux (Ubuntu 22.04)
    • Intel(R) OpenCL on
      11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80 Ghz OpenCL 3.0
    • Intel(R) oneAPI Unified Runtime over Level-Zero on
      Intel(R) Iris(R) Xe Graphics 12.0.0

We use the latest available CTS in our validation, but sycl-rel-6.0.0 is an
old branch already and there were some CTS changes made which make them fail.

Known failures are:

  • test_device CTS test fails because some OpenCL-specific device info queries
    do not throw exceptions on non-OpenCL backends. See KhronosGroup/SYCL-Docs#625
  • test_header CTS target cannot be compiled, because definition of
    SYCL_LANGUAGE_VERSION does not match the latest version of the SYCL 2020
    specification. See KhronosGroup/SYCL-Docs#634
  • test_language CTS target cannot be compiled, because the compiler does not
    abide to all new rules for constant-evaluated expression from the latest
    version of the SYCL 2020 specification. See KhronosGroup/SYCL-Docs#388
  • multi_ptr CTS target cannot be compiled, because implementation for
    decorated_generic_ptr and raw_generic_ptr aliases is missing.
    See KhronosGroup/SYCL-Docs#598

How to use

This release does not provide a pre-built binaries of our SYCL compiler and
simply marks a known good commit on a corresponding release branch which can be
used for building the compiler and the runtime for your needs. To do so, follow
