Checklist:

Completeness and readability

• I have commented my code, particularly in hard-to-understand areas.
• I have updated the documentation to reflect the changes or created a separate PR with updates and provided its number in the description, if necessary.
• Git commit message contains an appropriate signed-off-by string (see CONTRIBUTING.md for details).
• I have resolved any merge conflicts that might occur with the base branch.

Testing

• I have run it locally and tested the changes extensively.
• All CI jobs are green or I have provided justification why they aren't.
• I have extended testing suite if new functionality was introduced in this PR.

Performance

• I have measured performance for affected algorithms using scikit-learn_bench and provided at least a summary table with measured data, if performance change is expected.
• I have provided justification why performance and/or quality metrics have changed or why changes are not expected.
• I have extended the benchmarking suite and provided a corresponding scikit-learn_bench PR if new measurable functionality was introduced in this PR.

@Vika-F Would this bring these functions into the ABI checks?

@Vika-F Would this bring these functions into the ABI checks?

@david-cortes-intel No, those changes should not affect the ABI as those functions are defined in cpp/daal/src (which contents are considered to have hidden visibility by default), and are not exported with DAAL_EXPORT.

It looks like this warning should be addressed instead of being ignored.

I think the only way to address this issue is to create a ticket for DPL team, but it will likely block the current PR. @ethanglaser Could you please create a ticket for DPL team and and a remark here to remove such line when the task is done?

[ethanglaser]

Yes, this it outside of our library's scope otherwise I'd address it myself. Will post link to ticket once I create.

FYI latest CEV run is in PR description. Still some errors on sklearnex build side, oneDAL build errors are resolved.

[david-cortes-intel]

CI errors are in BasicStatistics, so probably not related to these changes.

Pull request overview

This PR addresses a Windows build failure related to CEV by adjusting linkage on a couple of DAAL decision-tree helper templates and by silencing a Clang warning in the oneAPI DPC++ sort implementation.

Changes:

• Suppress Clang -Wunused-template warnings around the DPL kernel template include in the DPC++ sort primitive.
• Remove static (internal linkage) from two DAAL templated helper functions used in decision tree model code.
