error: could not compile `untitled1` due to previous error

Is this because the build-std tool does not support aarch64?

I also found this in r/rust. I thought this is a bug of zig at that time, but now I find it's a regression of rust.

So It's pr https://github.com/rust-lang/rust/pull/83655 via https://github.com/rust-lang/rust/commit/003d8d3f56848b6f3833340e859b089a09aea36a

It also cause another breakage: https://github.com/rust-lang/rust/issues/89626

[SparrowLii]

This problem can currently be solved by adding the compilation parameter -Ctarget-feature=-outline-atomics, so I think this issue can be closed.

[ehuss]

I'm going to reopen. We want build-std to "just work", and not working on a tier-1 platform without a special option isn't the kind of experience we would like.

I'm still uncertain about the solution here. I don't want to hard-code special rules inside cargo. I also don't want to require building C code. I don't yet fully understand this situation, though. rust-lang/rust#83655 contains some more discussion.

[workingjubilee]

This was a mistake on my part, my apologies. It will be corrected.

[jyn514]

This will be fixed by https://github.com/rust-lang/rust/pull/102579.

[jyn514]

https://github.com/rust-lang/rust/pull/113269 has landed :)

[workingjubilee]

Ah, thank you so much!
