The compiler at the minute doesn't generate unified syntax for VFP instructions - therefore expecting the instructions of that form to work correctly is wrong. I think the correct way of writing this is void round_int(void) { __asm__ __volatile__("fconstd d1,%G0" : : "Dv"(0.5f) : "d1"); } And then it would work. We really do need to transition to unified syntax for VFP instructions. cheers Ramana
