Release Intel SYCL Compiler release 6.0.0 · intel/llvm (original) (raw)

Dependencies included in the release

Components included in the release

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>().

SYCL CTS

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:

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
Get Started Guide

Known issues

This section describes additional issues which were reported that are not listed in the corresponding section of the detailed changelog.

error: SYCL kernel cannot call a variadic function

Compilation error like this will be reported for applications that use sycl::vec::operator[] (either directly, or indirectly through built-ins like sycl::group_broadcast) when compiled on Windows in Debug mode using clang.exe compiler driver.

There are a couple of workarounds available to it:

Note that if your environment and application is not what described above (sycl::vec::operator[] usage on Windows in Debug mode through clang.exe compiler driver), then the error is expected to be legit, i.e. device code contains some illegal construct.
