Thanks for your update.
I do not have any further comments on the code change.

Do we have some test cases in pre_checkin or extended to verify this feature?

[hcman2]

Test cases added in pre_checkin/wave32.

Thanks for adding the test cases.
It looks like we need to add the new folder name in pytest.ini to avoid the following warning message.

/var/jenkins_home/workspace/clang_precheckin_Tensile_PR-1625/4dRKDTY1u/tensile/Tensile/Tests/yaml_only/test_config.py:76: PytestUnknownMarkWarning: Unknown pytest.mark.wave32 - is this a typo? You can register custom marks to avoid this warning - for details, see https://docs.pytest.org/en/stable/how-to/mark.html
return getattr(pytest.mark, name)
