Description Jason Tibbitts 2018-01-12 23:41:20 UTC 
I hate to file this bug because I doubt there's much the Fedora maintainer can really do about it.  I don't really even know whether to file it here or with llvm or somewhere else.  But here goes.

I help maintain the cyrus-imapd package, which provides an IMAP/JMAP/calendaring server.  cyrus-imapd supports virus scanning via the cyr_virusscan command, which is linked against clamav-libs.  The cyrus-imapd test suite contains a test which puts a couple of messages containing the EICAR test signature in a mailbox and then runs cyr_virusscan to see if they are found.

On ppc64 _only_ (ppc64le is fine) the invocation of cyr_virusscan fails with:

cyr_virusscan: llvm/lib/Target/PowerPC/PPCCodeEmitter.cpp:156: unsigned int {anonymous}::PPCCodeEmitter::getMachineOpValue(const llvm::MachineInstr&, const llvm::MachineOperand&): Assertion `MovePCtoLROffset && "MovePCtoLR not seen yet?"' failed.

I have pretty much no idea at all what that means.  Google turns up this thread: http://lists.llvm.org/pipermail/llvm-dev/2010-October/035539.html but that's about it.

For now I'm disabling clamav support on just ppc64.  I will go ahead and block F-ExcludeArch-ppc64 even though technically this isn't an excluded package, just an excluded minor feature.  Hopefully someone will have some idea of what's going on.

Hi Tibbs 

Hum the thread mention if from 2010 ...
Can you put here the link of the builds please ?
Comment 2 Jason Tibbitts 2018-01-27 03:08:17 UTC 
Yes, the thread is old but it's pretty much the only thing I could find that's remotely relevant.

I only managed to get that error output by poking around in the mock buildroot manually on one of the ppc64 test instances.  And sadly now with no package changes I can't even build the thing in rawhide for some reason.

Still, here's an F27 build which is constructed to show the problem: https://koji.fedoraproject.org/koji/taskinfo?taskID=24479168

The failure is detailed way down at the bottom of the build log.
Comment 3 Sergio Basto 2018-02-05 00:53:39 UTC 
I made a build today and "just" fail on test [1] and don't see any Assertion ...

Comment 4 Fedora End Of Life 2018-02-20 15:28:24 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
Comment 5 Sergio Basto 2018-03-09 02:11:11 UTC 
we may try something like :

Comment 6 Sergio Basto 2018-03-12 00:34:44 UTC 
This thread [1] suggests that we disable build with --enable-llvm=no on ppc64

Comment 13 Jason Tibbitts 2018-03-30 17:30:54 UTC 
Thanks for this; I was able to re-enable the clamav functionality for ppc64 in cyrus-imapd and the test suite no longer fails.
Comment 14 Sergio Basto 2018-04-01 02:39:33 UTC 
cool , closing it as upstream
