I'm ok if you are happy with it.. |
…2097) Also reformat Polly. Fixes llvm#79834. (cherry picked from commit 8de2300)
|
Hi @owenca (or anyone else). If you would like to add a note about this fix in the release notes (completely optional). Please reply to this comment with a one or two sentence description of the fix. |
|
This is just a bug fix requested to be cherry picked, so I don't think we need to add a note about it in the release note. |
|
Please add release notes for formatting fixes in stable release branches. In general any formatting changes in minor revisions on a stable branch should be in the release notes as bugfixes I think. Have a great day! |
|
The only bug fix for clang-format is in the change log section of 18.1.4 release notes, so I'm not sure if it's useful to repeat it at the top of the release notes. For 18.1.5, there will be a reversion of behavior from 18.1.1. I'll definitely add that to the release notes. |

Thanks for the reply. I guess the reason for use not getting this on jammy is that the builds seems broken for some reason. |
