[LLVMdev] Free Variables In a Loop.

[Rohith Goparaju]

Hi ,

   I'm working on a project in which i need to find out all free variables
in a loop. I need to find all variables used inside a loop and that are not
declared(allocated) in the loop. I'm confused about what symbol tables to
use to get hold of such variables.

Thanks,
Rohith.
