Update to a new nightly version

[Bobo1239]

Includes rust-lang/rust#83592 and rust-lang/rust#85276 which were needed
to build correctly again after rustc's upgrade to LLVM 12.

Fixes #135.

Looks like the ppc builder is unhappy here.

Yeah, seems like there's still something going wrong after LLVM 12. Only tested x86_64 locally so there was a good chance that one of the other platforms miscompiles. Will try to take a look at the failure.

Thanks!

Thanks a lot for rust-lang/rust#85276 -- I mentioned in the last informal meeting we still had relocations going on but did not have time to look into what was going on, so it is great to see that being solved.

For the CI failure, I would suggest giving a quick try at disabling optimizations in the Hacking menu to discard LLVM opt issues.

Thanks so much for chasing down this details!

Looks like there's a new clippy error.

[Bobo1239]

Apparently CLIPPY=1 somehow doesn't work together with O=builddir. (it just uses regular rustc without emitting any clippy warnings)

[ojeda]

Good catch, created issue.

• ✔️ Commit 67c7a71: Looks fine!

[Bobo1239]

Removed the clippy fix from the commit message again since #319 took care of that.

[ojeda]

Yes!
