Description Fedora Release Engineering 2020-08-03 17:45:21 UTC 
libaio failed to build from source in Fedora rawhide/f33

https://koji.fedoraproject.org/koji/taskinfo?taskID=47992138


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_33_Mass_Rebuild
Please fix libaio at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
libaio will be orphaned. Before branching of Fedora 34,
libaio will be retired, if it still fails to build.

LTO related failure
Comment 5 Jeff Law 2020-08-07 15:55:20 UTC 
Strangely this didnt show up here:

https://kojipkgs.fedoraproject.org/mass-rebuild/f33-failures.html


It worked in my tester in mid July.   Regardless I an see that it uses ASMs to implement symbol versioning which is known not to work with LTO.  That's an indication we got different partitions during the LTO phase, which can happen.
I'll disable LTO.

The best long term fix is to move away from ASMs for symbol versioning and instead use the symbol versioning attributes.   However, this package is small enough that we may be able to instead use -fpartition=none to work around the ASM issues.  We'll evaluate the latter as we walk through the opted out packages again.
Comment 6 Jeff Moyer 2020-08-07 16:00:59 UTC 
Is there any benefit to using LTO for libaio?  It's just a small shim around the sytem call interface.
Comment 7 Jeff Law 2020-08-07 16:03:13 UTC 
Probably little, if any.   But dropping those top level ASMs and using attributes instead is still the right way to go from a code cleanliness standpoint.
