But how can CFG help in loop dependency analysis. I want to find out
whether the iterations of a particular loop are paralleizable. For this
i need to get the loop index variable and anyother variables depending
on that.


I got one parser named 'ELSA'. It has the option to write the AST into
an XML file. I think i can use some xml parser to get an AST data
structure from that. But is there any other tool that provides an AST
that can be directly used in my program?
