[LLVMdev] How to get function information in a generated call graph?

[kobe James]

Hi All, 

I use opt -dot-callgraph test.bc to generate a dot format call  graph from the 
given bitcode file. I am just wondering if there is any  implementation to get 
information for each function, which is a node in  the .dot file,  in a call 
graph? (e.g. which file the function is in,  and the specific line number) 


Thanks, 
Chen
