CSC448: Program Analysis I: Control Flow Graphs IV [88/133]

The graphs are generated using the dot program from the Graphviz package.

If you want to try this yourself, call the buildDiagrams in the BuildDiagrams class from the Compile class:

    new BuildDiagrams ().buildDiagrams (basename, cu);

This produces a dot input file for each non-native block. For example: file:test024_entry.dot

dot converts this kind of file into a Postscript file (making layout decisions in the process):

$ (cd tests; for i in *.dot; do dot -Gsize="8,10" -Tps $i -o `echo $i|basename $i .dot`.ps; done)

Alternatively, you can produce GIF output instead of Postscript:

$ (cd tests; for i in *.dot; do dot -Tgif $i -o `echo $i|basename $i .dot`.gif; done)
