--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I think --param max-pending-list-length=0 is just a pathological setting that
doesn't make much sense, it basically kills all sched-deps handling and
replaces it with just dependencies on the single element flush list.
That said, when looking at what dependencies are there on the testcase without
that param, I don't see any dependencies between those insns (clobber of
<retval>, set ax <retval> and use ax) and the two the scheduler inserts in
between those that upset mode switching.
