Comment 1 Martin Stransky 2023-08-29 12:31:11 UTC 
Jakub, any idea where to look at? GCC version seems to be the same on Rawhide and Fedora 39 but we're getting this failure on Rawhide only.
Thanks.
Comment 2 Jakub Jelinek 2023-08-29 13:36:19 UTC 
See https://bugzilla.mozilla.org/show_bug.cgi?id=1846703 and https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108941 and https://sourceware.org/bugzilla/show_bug.cgi?id=30578
It is an unfortunate change in binutils that the author fails to acknowledge as a bug.  GCC can't really do anything there.  ffmpeg/ffvpx can just avoid using inline asm
in these cases altogether (I don't really understand why it doesn't trust the compiler which knows which target have truncating shifts and which don't), or do what ffmpeg
did upstream.
Comment 3 Martin Stransky 2023-08-30 11:26:28 UTC 
Will take upstream patch then, Thanks.
