search for: pgmdepgraph

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?

I want to use PgmDependenceGraph pass , but my pass cannot work with PgmDependenceGraph. I tried again in Hello2 pass, and it could not work also. The following is I did with llvm/lib/Transforms/Hello.cpp: 1.insert #include "llvm/Analysis/PgmDependenceGraph.h" in Hello.cpp. 2.insert AU.addRequired<PgmDependenceGraph>() in the getAnalysisUsage(AnalysisUsage &AU) of Hello2.
