I want to find buffer overflows from general C programs, a bit like SAFECode :). To quicken the dataflow analysis, I wished to slice operands of character strings from C program using pgmdepgraph, but now, I thought I have to use def-use and use-def chain. Do you think it has any sense?

What specifically do you mean by slicing operands of character strings? Can you give a small example? -Chris -- http://llvm.cs.uiuc.edu/ http://nondot.org/sabre/
