--- Comment #14 from Jeffrey A. Law <law at redhat dot com> ---
I think we can fix this by just queueing the SCHED_GROUP_P insn for a single
cycle rather than for its full cost from within prune_ready_list. That will
cause us to reexamine the ready list each cycle. If some non-SCHED_GROUP_P
becomes ready before the SCHED_GROUP_P insn is ready, then the
non-SCHED_GROUP_P insn will go back to the queue because it's not part of the
scheduling group. Which is exactly what we want.
I'm testing with that fix now.
