...cfg: opt -disable-output -view-cfg ir.ll You may want to use -view-cfg-only rather than -view-cfg if you are not interested in the instructions, only the cfg. You could probably also do something like the following to output the cfg after each pass: opt -pass1 -view-cfg -pass2 -view-cfg ... -passN -view-cfg file.ll Ciao, Duncan.

A dumb question -- is there a way to dump cfg after each pass, something like: --print-cfg-after=sccp, or is there a standard post-processing script that builds the cfg vcg/dot file from the ir dump?

...you devise something better? For example, could you extend PassManager with a method that calls all of the passes's initialization methods? In other words, could you easily support something like: > > PassManager.add (Pass1); > PassManager.add (Pass2); > ... > PassManager.add (PassN); > PassManager.initializeAllPasses (); > PassManager.run(); > > > ... or could the PassManager::add() method automatically initialize the pass? Other possibilities may exists which are better as well; these are just the first two I've thought of. Neither of those will work....
