Okay, but isn't this redundant to the following code in try_replace_reg ():

static int
try_replace_reg (from, to, insn)
     rtx from, to, insn;
{
  rtx note = find_reg_equal_equiv_note (insn);
  ...
  /* If there is already a NOTE, update the expression in it with our
     replacement.  */
  else if (note != 0)
    XEXP (note, 0) = simplify_replace_rtx (XEXP (note, 0), from, to);


Does try_replace_reg still need the above code?
