Hi, I have investigated the PDG plugin with the example below. I Know little about PDGs. I would like to Know the semantic of the PDG nodes and edges (e.g. what does it mean blue edges, dark edges, and dotted edges? And about the color of the nodes? What are circle nodes, rectangle nodes, ... ). Is there some reference for reading? Is it possible use the PDG to help the value analysis? Maybe with the slevel? I attached the graphs. I would like to know if is possible to create a Control Flow Graph as showed in the attached figure. Exist another plugin for this or another way to obtain the same information? Best regards, Rovedy //------------------------------------------------------------------------------------------------- void main() { int a=0,b=0,c=0; a=4; if ( a > 5 ) { b = 3; c = a + 5; return ; } else { b = 4; a = foo(a); c = a+5; } } -------------- next part -------------- An HTML attachment was scrubbed...
