CFG variable type information

Hey Users!

I have two question regarding the CFG:

1. How is typeinformation of variables saved?
In the manual (“Clang” CFE Internals Manual — Clang 16.0.0git documentation) there is a code example and a corresponding Basic Block list. However the BB-List does not show the variables type (int). I do assume that it is saved, but i can not work out how.

2. Following up: Where is this typeinformation saved and how can i access it?

I still have a hard time infering these things just from code/doxygen, so if someone could help out, it'd be much appreciated.

Thanks in advance and best regards.
