A question about the data dependency graph about progex HOT 2 CLOSED

This is related to the algorithm used for extracting data-dependence relations. The algorithm used in PROGEX first performs DEF-USE analysis, which specifies which variables are defined or used in every statement of the program. Then it traverses the program's CFG and utilizes the gathered DEF-USE information in order to extract data-dependence relations among statements.

Other than this, the CFG is also used in the visualization phase to present a more comprehensible graph for the human user.

If you only intend to consume the DDG graph via machine/programs, you can easily ignore the CFG and only traverse the DDG edges.

Thanks for your answer.
Ignoring the CFG is easy but I'm just curious about your design.
Your work does help me a lot.
Thanks again.
