Here is a corrected change for push_reload (reload.c):

	    (out != 0 && MATCHES (reload_out[i], out)
	     && (in == 0 || reload_in[i] == 0 || MATCHES (reload_in[i], in)))))
      break;

  /* Reloading a plain reg for input can match a reload to postincrement
     that reg, since the postincrement's value is the right value.
     Likewise, it can match a preincrement reload, since we regard
     the preincrementation as happening before any ref in this insn
     to that register.  */
  if (i == n_reloads)
    for (i = 0; i < n_reloads; i++)
      if (reload_reg_class[i] == class
	  && reload_strict_low[i] == strict_low
	  && out == 0 && reload_out[i] == 0
	  && ((GET_CODE (in) == REG
	       && (GET_CODE (reload_in[i]) == POST_INC
