ucmpdi2 and cmpdi2

[Rune Torgersen]

Hi

I have a function that does a switch statement on a long long or
unsinged long long and get teh follwing compiler warnings when making a
module:

WARNING: "__ucmpdi2"
[/home/runet/source/hardware_1.1/cpu1/src/drivers/test_bug.ko]
undefined!
WARNING: "__cmpdi2"
[/home/runet/source/hardware_1.1/cpu1/src/drivers/test_bug.ko]
undefined!

And of course it fails to load.

The weird thingis that it works if I instead of using a long long, use a
[u]int64_t.
Is this a compiler error or something else?

Here is my module source:

{
    long long   t1;
    unsigned long long   t2;
    
    t1 = 0x100;
    t2 = 0x200;

    switch(t1)
    {
        case 0x01: 
            printk("c1\n");
        break;   
        default:
            printk("def1\n");
        break;
    }

    switch(t2)
    {
        case 0x02: 
            printk("c2\n");
        break;   
        default:
            printk("def2\n");
        break;
    }
}
