Confirmed.

enum { gcr0_8259_bit = 0x20000000, gcr0_reset_bit = 0x80000000 };
void decode_opic_address(int *);
void hw_opic_io_read_buffer(int index)
{
  unsigned reg = 0;
  decode_opic_address(&index);
  switch (index)
    {
    case 0:
      reg |= gcr0_8259_bit;
    }
  sim_io_printf_filtered2 (index, reg);
}
