</div>Overall this looks great. There are a few misspelled words in the comments resulting from typos (e.g., 'Elememnts'), so it's probably worth running a spell-checker.<br>
<br>
Besides specific comments (below), I'm concerned about the impact on CFG-construction time when scope building is *not* enabled. This is currently the common case for uses of the CFG in Sema. I think there shouldn't be any noticeable penalty since most of the logic is guarded with a flag, but it is worth verifying.<br>

</div>For the test cases, how do you plan on testing it? Also, since these are all small tests, please include them in one file (if possible).<br>
<br></blockquote><div>You did mention something about similar case in test folder, but I can't currently locate your message. Some suggestions would be useful, e.g. how to set up test for feature that is currently turned off.</div>

Why this line change? The "loop back" block is very important for analyzer diagnostics. Is this because 'addAutomaticObjDtors' might create a block?<br>
