Hi there,

I'm the maintainer of rust for opensuse. I have been working to include rust1.54 recently but I have noticed that with distro llvm11 on s390x that rust fails to build. Rust1.54 works correctly on s390x with distro llvm12 or with the bundled llvm that rust provides.

The build error is (a longer extract is below) - I'm quite confident that the error is not in the "either" crate, but this is a codegen issue with llvm. Since i have access to an s390x machine and a reproduction environment, I am happy to help with bisecting this with some guidance (especially to find what changes between llvm11 -> 12 that resolves this).

Thanks for your advice and help!

This sounds like #80810 to me. https://bugs.llvm.org/show_bug.cgi?id=49322 / https://reviews.llvm.org/D97514

Indeed, I believe this is a duplicate of that issue. I will talk to the llvm people at suse about backporting those fixes to llvm 11. Thanks!
