Scope of work to fix sched REG_DEAD handling?


Any idea what's involved in fixing the schedulers so that they
don't misplace the REG_DEAD notes?  I'm willing to take a look
at fixing them so that other optimizations can be enabled (such
as having delete_computation recursively delete insns).

Also, what's involved in getting additional constant propagation
to work on cc0 machines?  If I recall the web announcement
said that the new work currently doesn't support cc0 machines.
