LiveVariables inside clang-tidy check


I am developing a clang-tidy check to perform some sort of parameter validation. I can access CFG information in my check, and I am trying to use LiveVariables information too, but I haven’t been able to do so. Apparently, it is possible to do it for a clang static analyzer check, as mentioned here:

However, when I try to include LiveVariables info in my check, the result is similar to the one reported here:

Does anyone know if it is possible to use such information in a clang-tidy check?
