Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bernds at redhat dot com --- Comment #8 from Jeffrey A. Law <law at redhat dot com> --- Bernd. There's a belief this may be a combiner issue, so it might be something you'd want to poke at. I can still trigger this failure on the trunk using -ftree-loop-if-convert on an aarch64 native. If you need access to an aarch64 system, let me know, I've got one provisioned.
