There's some awful macro magic:

#define PORT(name, len, val) \
static unsigned __attribute__((unused)) in_##name(void) \
{ \
    unsigned res = qpci_io_read##len(dev, dev_base+(val)); \
    g_test_message("*%s -> %x\n", #name, res); \
    return res; \
} \
static void out_##name(unsigned v) \
{ \
    g_test_message("%x -> *%s\n", v, #name); \
    qpci_io_write##len(dev, dev_base+(val), v); \
}

PORT(Timer, l, 0x48)
PORT(IntrMask, w, 0x3c)
PORT(IntrStatus, w, 0x3E)
PORT(TimerInt, l, 0x54)
