I updated our project recently to use a newer version of clang (we're at r127188 now). That version made our modified ccc-analyze script stop working, so updated that from TOT clang as well. I noticed in the new script a new environment variable check "CCC_UBI" that uses Ubigraph to visualize something... but what? I tried making a simple project with a few kinds of static analyzer errors, but nothing ever shows up in my ubigraph window. What's this feature for and what should I see graphed?
For future reference, the correct list for questions on the analyzer is cfe-dev, not llvmdev.
CCC_UBI is meant to display the analysis path graph (aka "exploded graph") as it gets explored by the analyzer. I haven't run it in a while, so it may be broken. I will investigate.
I think the trick is to use a debug build of Clang. The ubigraph support is not enabled in a release build as it is in a hot path of the analyzer. I switched to using a debug build and the ubigraph support worked for me. You also need the 'ubiviz' script in your path.
Thanks - I'll give it a try.
