Sumit, what you're describing with 'add eax ebx' is a machine- 
language string GP representation.  ECJ does not support such a  
representation at this time -- it uses a parse-tree representation.   
If you're looking for machine language instructions, the ECJ website  
has some pointers to other systems that may fit your bill better.   
You could also google for 'Discipulus' as well.
