dave,
i have a patch for this. i am doing regtests now and will have a patch posted
first thing tomorrow.
the bug is in dce.c:deletable_insn_p. The problem is that it does not look
inside of parallels. so even though it supposed to not delete top level
unspecs and top level sets, if they are buried inside a parallel, it does not
consider them top level.
