One important thing I forgot, that you cant rely on `ProgramState` due to
tidy's constraints. Btw, how do you plan to make this into a tidy checker? To
me it seems like it would amplify the already existing false positive issues

Hi @lebedev.ri!
Thanks for the question. I was not sure as to where exactly put the files. The
important thing for me is that the `StackUsageMeasuringVisitor` should be
reachable from the clang-tidy checker. (For the bigger picture please refer to

Hi @Szelethus !
Thanks for all your detailed and helpful input, I will make sure to go over all
the comments and answer them, but it will take some time.
A bit more background information on this checker and how it came to be might
help you and others to understand so

Without seeing the full picture (i.e. what you want to do with the clang-tidy
check) it is hard to tell,
but are you *very* sure all this logic should be in
`clang/lib/StaticAnalyzer/`, and not in `clang/lib/Analysis/` ?

I think the idea for a checker like this is great! I left some inline comments,
but most of them are minor nits. I have some general remarks to make however:
- Your code lacks comments, especially a nice docume

Hi!
Always great to see a new checker! I've started working in this project little
over half a year ago, so I don't claim to be an expert, read my remarks as
such! It'll be some time before I go through the entire code, but so far here
are the things that caught my e
