Comment 1 Martin Stransky 2021-03-01 15:33:47 UTC

Build log:
https://kojipkgs.fedoraproject.org//work/tasks/7290/62877290/build.log

Comment 2 Dan Horák 2021-03-01 15:36:09 UTC

I have seen the same error when building ghdl in rawhide, it seems to be related to LLVM 12.

Comment 3 Dan Horák 2021-03-02 12:31:45 UTC

I have filed a separate clang issue as bug 1934065

Comment 4 Martin Stransky 2021-03-13 15:31:58 UTC

This one affects Fedora 34 too:
https://koji.fedoraproject.org/koji/taskinfo?taskID=63648849

Comment 5 Dan Horák 2021-03-16 10:49:46 UTC

A fix got accepted to llvm/clang, so we should get a new build soon to unblock Firefox ...

Comment 6 Dan Horák 2021-04-06 08:37:10 UTC

starting with firefox-87.0-4 the ppc64le builds work again
