Sir, there is something which i would like to point out There is no declaration of a structure in GIMPLE For eg if the C file has struct a { int x,y; }; the corrosponding GIMPLE representation is just typedef struct a struct struct a (even if the typedef is not present in the C file !!!) Another thing is that in a function declaration the type of the parameters is not specified in gimple I am currently working with the IIT (indian institute of technology) Powai The aim of my project is to incorporate this information in the gimple file If u could please guide me a little on this i would be highly grateful thank you Rohan Shah __________________________________________________ Do You Yahoo!?
