For me, they always get set right before the call: b6: 29 e2 ldi r18, 0x29 ; 41 b8: 39 e0 ldi r19, 0x09 ; 9 ba: 40 e0 ldi r20, 0x00 ; 0 bc: 50 e0 ldi r21, 0x00 ; 0 be: 0e 94 72 00 call 0xe4 ; 0xe4 <__mulsi3> So you'd have to explain which compiler version exactly you are using (including patches). Btw., when using floating-point, please do /always/ append -lm to the linker command-line (but it doesn't change anything in your case). -- cheers, J"org .-.-. --... ...-- -.. .
