--- Comment #6 from Jeffrey A. Law <law at redhat dot com> ---
You certainly don't want to put something between DOM and phi-only-cprop. Jump
threading will tend to expose lots of degenerate PHIs. phi-only-cprop
eliminates those degenerates. We could have used the normal cprop code, but it
seemed too heavy-weight for the cleanups we wanted to do.
One could argue we want a phi-only-cprop cleanup after VRP since it threads
jumps too.
