Pull Request Overview

This PR reverts previous changes that pinned container image SHAs to enable the upgrade to clang 20. The key changes include removing SHA-based version locking for various container images used in the pipeline, restoring them to tag-based references, and aligning with the upstream changes in related .NET runtime repositories.

Comments suppressed due to low confidence (1)

• Removing the SHA pin may lead to non-deterministic builds if the upstream container image is updated unexpectedly. Consider verifying that using the tag-only reference will not adversely affect stability.

This all looks unrelated. Look OK @sbomer?

I think this means that azdo rejected the command and it did not run the extra legs. I do not see any NativeAOT Arm32 runs that got the previous attempt reverted.

Thanks. I looked at the pipelines that were run and I wondered if those were missed. Thanks for kicking them off for real.

None of the failures look related

Also, the SDK non-deterministic crash that we suspect is related to clang 20 did not go away with the revert dotnet/sdk#47580 (comment) so it is unrelated.
