Change the loop to rename the generated assembly
stub __seek and treat it like any other system call
(no special code; just the name change).
Then add this C function:
int _seek(vlong*, int, vlong, int);
vlong
seek(int fd, vlong off, int whence)
{
vlong ret;
if(_seek(&ret, fd, off, whence) == -1)
return -1;
return ret;
}
You should never ask "how do I write this in assembly?"
You should ask "how do I *not* write this in assembly?"

P. S. You might also change gcc not to prefix all the
C functions with underscores. (I'm sure there's an option.)
Real systems gave that up a long time ago.
