Comment 1 Dan Horák 2020-07-30 10:12:03 UTC

I have reproduced that locally, seems it's a bug in LLVM, see info bellow

Comment 2 Dan Horák 2020-07-30 10:18:13 UTC

And it happens with both llvm-10.0.0-1.fc32.ppc64le and llvm-10.0.1-1.fc32.ppc64le. I'm going to try to downgrade rust.

Comment 3 Dan Horák 2020-07-30 10:49:04 UTC

And there is no problem when rust has been downgraded from rust-1.45.0-1.fc32.ppc64le back to rust-1.44.1-1.fc32.ppc64le

Comment 4 Dan Horák 2020-07-30 11:46:31 UTC

backtrace produced with rust-1.45.0-1.fc32.ppc64le and llvm-libs-10.0.1-1.fc32.ppc64le

Comment 5 Tom Stellard 2020-07-30 15:26:33 UTC

Can you recompile with the '-C save-temps' option and then post the output llvm bitcode to this bug?

Comment 6 Dan Horák 2020-07-30 16:56:49 UTC

done, download from http://fedora.danny.cz/ff79-rust-temps.tar.bz2 (~600MB), if needed we can reproduce that on an internal machine too

Comment 7 Tom Stellard 2020-07-31 00:07:08 UTC

I filed an upstream bug for this and you can find a reduced test case attached to that bug.

Comment 8 Jan Horak 2020-08-07 12:55:11 UTC

Same on RHEL 8.3.

Comment 9 Dan Horák 2020-08-07 13:08:46 UTC

(In reply to Jan Horak from comment #8)
> Same on RHEL 8.3.

This bug has been cloned to RHEL already, so hopefully we will have a fixed LLVM soon.

Comment 13 Dan Horák 2020-09-03 15:51:30 UTC

Hi Tom,
so this has been fixed for F-32 and in Rawhide, but how about F-33? I can't find a build for either llvm or llvm10 with the fix. Isn't it still missing?

Comment 14 serge_sans_paille 2020-09-04 07:46:57 UTC

Hey Dan,

Comment 17 Martin Stransky 2020-09-14 11:45:56 UTC

The same seems to happen on F33/x390x. Can we have an update for Fedora 33?

https://koji.fedoraproject.org/koji/taskinfo?taskID=51424580
https://kojipkgs.fedoraproject.org//work/tasks/4580/51424580/build.log

Comment 18 Josh Stone 2020-09-14 16:33:32 UTC

@Martin -- the patch in question here is entirely specific to the PowerPC backend, so we'd have to investigate s390x failures separately. However, your error was a SIGKILL, which usually comes from being out of memory -- I know I've had to disable s390x debuginfo for the build of rustc itself due to memory constraints.
