duplicate with #98285 ?

@Patryk27

Contributor Author

Kinda, that one doesn't contain the recent commit from yesterday that fixes the AVR bug I've linked 😅 (since it uses llvm-project from two days ago)

I guess I'll just rebase my PR after #98285 gets merged.

Perf result seems to be noise, it seems to be the opposite of the results on the previous commit: https://perf.rust-lang.org/compare.html?start=f342bea9d19f14616c6559312552e6d0ee529cfd&end=5b8cf49c51833ee5d27ae2e8e179337dbb9f14d7&stat=instructions:u

Beta nominating as fix for the P-critical miscompile in #98568. The update also includes a fix for an AVR-only miscompile (#98167), as well as an assertion failure (#98076).

@nikic is it a problem if we backport by rolling forward to the latest commit here on beta? (rust-lang/llvm-project@c9e2e89...8b6b501)

Otherwise can create a targeted backport with a helper branch, but want to make sure there's no accidental mistakes missing a dependency on a previous commit here.

nikic commented Jul 9, 2022

@Mark-Simulacrum I think we need a separate backport branch here, because the LLVM fork has been rebased in the meantime, and I'm not confident that it will build on beta (specifically FreeBSD). And no, I don't think there are any relevant dependency commits.

OK, sounds good. I'll look into doing that.

There's a few more as-yet-unapproved/unmerged PRs that'll land later, but creating a partial rollup for now so that we can include at least some PRs in the first crater run.

Dropping regression label, agree that the results are likely noise. See #98925 (comment) for some graphs.
