   What does the chain-o-notes look like if we don't run the post reload flow
   pass?  I'm curious how this worked before.

Jeff, consider the code you removed here in update_flow_info() in both
instruction scheduler implementations the other day, both of which
looked something like:

	if (insn == first)
	    if (reload_completed && this_is_reg_dead_note)

And as I said my splits only run after reload.

This is why it always worked before, it isn't rocket science :-)
