Re: Where does __sdivsi3_i4 come from?

Hi,

Did you check that you are correctly linking against libgcc? IIRC, these symbs are used by libgcc to 
emulate math hardware instructions (yours should be about division, obviously) if they are not found 
on a certain architecture.

Hopes that helps,

Vincent
