Does this need backports to 3.12 and 3.13? |
Contributor
Looks like the relevant code is not in 3.13 or earlier, so I guess not. |

Yup, it's only a recent code (that's why I did 2 PRs). |

Hum, we have a failure: https://github.com/python/cpython/actions/runs/12200589926/job/34037087571. I'm not sure what happened :( |
Contributor

Ok, let's revert it for now while we investigate. |

Not sure we can do anything except wrapping the call in a function. Adding an allow list may seem too hard since the line would change everytime we change the code. Or we can just forget about the optimized unaligned load.
