)This is a patch/bugfix release for v6.0.0
and it is compatible with it. For compatibility with other releases, please see the corresponding documentation for v6.0.0
.
Intel(R) oneAPI DPC++/C++ Compiler version 2025.0 release 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.
We would like to specifically note that bugfixes and patches applied to 2025.0.X oneAPI patch releases do not match those made for this release.
Validation & quality expectationsIn 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 exhaustive 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 testsThe following hardware and software configurations were tested:
Driver versions listed as reported by sycl::device::get_info<info::device::driver_version>()
.
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 queriestest_header
CTS target cannot be compiled, because definition ofSYCL_LANGUAGE_VERSION
does not match the latest version of the SYCL 2020test_language
CTS target cannot be compiled, because the compiler does notmulti_ptr
CTS target can be compiled, but the test reports failure becausedecorated_generic_ptr
and raw_generic_ptr
aliases is missing.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

Changes sincev6.0.0
This patch release contains a fix for error: SYCL kernel cannot call a variadic function
issue mentioned in Known issues
section of the 6.0.0 release.
The issue should not be reproducible in most environment. Its reproducibility depends on implementation details of
specific C++ STL implementation that's installed on your system. However, we haven't seen a setup yet where it would
still be reproducible.
The fix has a potential to break ABI and to preserve compatibility, it won't kick in on systems where it would cause
an ABI-break (see the note above about reproducibility). If you still encounter it and do not care about binary
compatibility with previous releases, then you can define macro __SYCL_USE_PLAIN_ARRAY_AS_VEC_STORAGE=1
(before including sycl/sycl.hpp
)
to force-enable the fix.
