Hi Pypy devs!<br><br>I am a graduate student working on mining software repositories, specifically mining programming patterns (or rules) from code bases.[1] I would like to do some work mining patterns from Python programs and I could jump start that work if I could generate dependence graphs from python source files (or from the bytecode). <br>
<br>So I was wondering if Pypy does this already. Actually it would be a big help even if pypy only generated a control flow graph. From my quick skim of some of the source code it seems like it does this for RPython but I wasn't sure about regular python. If I could get a CFG I could then annotate it with the data dependence edges. <br>
<br>Any pointers to where I should look in the Pypy code would be appreciated! Additionally, if you feel having python pDG's would be helpful in Pypy's interpreter perhaps any work I do towards that end could be a starting point. <br>
<br>Thanks for the excellent work on Pypy!<br><br>[1] Here is some of my research group's previous work on pattern extraction <a href="http://doi.wiley.com/10.1002/smr.532" target="_blank">http://doi.wiley.com/10.1002/smr.532</a> (if you can't get the paper and would like it let me know)<br>

<br></blockquote></div><br>You're correct, we only generate full CFGs for RPython. The Python bytecode compiler for PyPy (and CPython) does have a CFG, but they're just local to functions so I don't think they're what you're looking for.<div>
