I meant the flags, but as this function uses variable arguments, I found the

flags on the starting position on the stack and R2. As the calling
convention 
for variable arguments seems to be different, I get the parameter from the 
stack. If there is some improvement that can be done, I would be willing to 
do the same heartily. :-)
