Description Fedora Release Engineering 2020-08-03 21:32:51 UTC 
yosys failed to build from source in Fedora rawhide/f33

https://koji.fedoraproject.org/koji/taskinfo?taskID=48363516


For details on the mass rebuild see:

https://fedoraproject.org/wiki/Fedora_33_Mass_Rebuild
Please fix yosys 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,
yosys will be orphaned. Before branching of Fedora 34,
yosys will be retired, if it still fails to build.

Comment 4 Jeff Law 2020-08-04 05:49:02 UTC 
There's an LTO component to this.  I'll take it for now.
Comment 5 Gabriel Somlo 2020-08-07 22:51:11 UTC 
Disabling LTO ("%define _lto_cflags %{nil}") allows the build to succeed: https://koji.fedoraproject.org/koji/taskinfo?taskID=48892455

Leaving the bug open for a potential proper LTO fix -- Thanks!
Comment 6 Igor Raits 2020-08-09 10:38:31 UTC 
There has been at least one successfull build after mass rebuild.
