--- Comment #1 from Roman Zhuykov <zhroma at gcc dot gnu.org> ---
I want to ping this meta-bug and kindly ask Jakub/Honza to look at it.  I've
just rechecked that ICE described in bug 85426 comment 4 presents on current
trunk.  While PR89116 example "unfortunately" shows no ICE at the moment.

Issue is still the same - we ask cfg_layout_redirect_edge_and_branch_force to
redirect a crossing jump.

With my local (still WIP) modulo-sched features, SMS pass can be used on x86,
where -freorder-blocks-and-partition is enabled by default.  So, this assertion
failure becomes much more annoying, even bootstrap failed on it in some
specific conditions.
