Long division on Nios 2

Hi there I have a question: Has anybody performed "long division" on Nios-2? I mean 64-bit/64-bit signed and unsigned division with [unsigned] long long of [unsigned] long data types ...

Yoo-hoo!

does ANY 64-bit operation work on Nios-2? I mean there are no "movdi" (for DItype) patterns, right?

I just want to know what should have happened when compiling s'thing like:

unsigned long long a = 0xAAAAAAAAAAAAAAAA;

unsigned long long b = 0x5555555555555555;

unsigned long long c;

c = a/b;

???

kind regards
