Description of problem:
Rust crashes on ppc64le and s390x when compiling the "ring" crate, the ppc64le and s390x backtraces differ only in minor details.

Version-Release number of selected component (if applicable):
rust-1.45.2-1.fc33
rust-1.44.1-1.fc33

How reproducible:
100%

Steps to Reproduce:
1. try building rust-ring package


Actual results:
https://koji.fedoraproject.org/koji/taskinfo?taskID=49475014


Expected results:
package built

Additional info:
It's a new package so there is no history with older rust or llvm versions.
Comment 1 Josh Stone 2020-08-19 16:03:55 UTC 
> thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', build.rs:372:34

This is not a compiler crash, but rather an action from ring's own build script.

 372   │     let (_, _, perlasm_format) = ASM_TARGETS
 373   │         .iter()
 374   │         .find(|entry| {
 375   │             let &(entry_arch, entry_os, _) = *entry;
 376   │             entry_arch == &target.arch && is_none_or_equals(entry_os, &target.os)
 377   │         })
 378   │         .unwrap();

Here is that target list:

 230   │ // None means "any OS" or "any target". The first match in sequence order is
 231   │ // taken.
 232   │ const ASM_TARGETS: &[(&str, Option<&str>, Option<&str>)] = &[
 233   │     ("x86_64", Some("ios"), Some("macosx")),
 234   │     ("x86_64", Some("macos"), Some("macosx")),
 235   │     ("x86_64", Some(WINDOWS), Some("nasm")),
 236   │     ("x86_64", None, Some("elf")),
 237   │     ("aarch64", Some("ios"), Some("ios64")),
 238   │     ("aarch64", None, Some("linux64")),
 239   │     ("x86", Some(WINDOWS), Some("win32n")),
 240   │     ("x86", Some("ios"), Some("macosx")),
 241   │     ("x86", None, Some("elf")),
 242   │     ("arm", Some("ios"), Some("ios32")),
 243   │     ("arm", None, Some("linux32")),
 244   │     ("wasm32", None, None),
 245   │ ];

So it would seem that ring just doesn't support ppc64le or s390x yet.
Comment 2 Peter Robinson 2020-08-19 17:04:29 UTC 
Digging further seems it's not supported upstream. There's a number of bugs around this bug the two main ones seem to be:
s390x: https://github.com/briansmith/ring/issues/986
ppc64le: https://github.com/briansmith/ring/issues/389

Plus some like there around support for generic C fallbacks: https://github.com/briansmith/ring/issues/971
Comment 3 Dan Horák 2020-08-20 13:58:08 UTC 
Thanks, Josh, I'll probably never understand what is rust trying to tell me :-)
Comment 4 Fedora Admin user for bugzilla script actions 2021-01-03 14:51:34 UTC 
This package has changed maintainer in the Fedora.
Reassigning to the new maintainer of this component.
Comment 5 Ben Cotton 2021-02-09 15:15:53 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 34 development cycle.
Changing version to 34.
