[LLVMdev] Why I cannot use PgmDependenceGraph?

[xia_yimin]

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?
