The default behavior for overflow is "panic in debug mode, wrap in release mode." So anything that does that does not need a note. Anything else should get one. |

In that case, we must add a note for |

Dupe of #34618? |

Yeah just adding a note here about overflow should be fine, but yeah looks like a dupe of #34618 so closing |

fetch_add fetch_sub pow
