I see code in dbr_schedule to delete them:
/* Delete any USE insns made by update_block; subsequent passes don't need
them or know how to deal with them. */
for (insn = first; insn; insn = next)
{
next = NEXT_INSN (insn);
if (NONJUMP_INSN_P (insn) && GET_CODE (PATTERN (insn)) == USE
&& INSN_P (XEXP (PATTERN (insn), 0)))
next = delete_related_insns (insn);
}
Why is that not working?
