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:

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
