I've tried to write a DFGPrinter based on the CFGPrinter, as you suggested, but encountered problems. The GraphWriter expects GraphTraits<GraphType>::nodes_begin()/nodes_end(). The way this is implemented in CFG.h, a function is a graph of basic blocks. A GraphTraits<Function*> inherits from GraphTraits<BasicB...

...predecessor/successor fashion, which requires you to 'walk' the graph in order to visit all nodes? (and what happens when you have disjointed DFGs?). inline comments follow...

Hi I'm trying to get a graphviz output (DOT) of a code I'm compiling. I want to see the DFG/CFG of the LLVM assembly, how the operations are chained together. The documentation mentions something about calling certain methods from within gdb, but isn't there some option when invoking the compiler (I've seen some -print-cfg and -dot-cfg options mentioned in some source files,
