Hi Paul, There are additional tests here that may answer your questions, https://reviews.llvm.org/rGe8475f78e2634d5d348d7ad746efc1e6526e72f5

In the review, Zach asked the question but I did not see a straight answer. What do these flags actually mean? What is the third state, with both flags off, implying not Trivial and not NonTrivial? (At the very least it seems that the names could be improved.)

Please read the code review which answers your question. A new flag is required. Thanks. ________________________________ From: David Blaikie <[email protected]> Sent: Tuesday, March 5, 2019 12:51:27 AM To: Aaron Smith; Reid Kleckner; Adrian Prantl; Jonas Devlieghere Cc: [email protected] Subject: Re: r354843 - [CGDebugInfo] Set NonTrivial DIFlag to a c++ record if it's not trivial Hi Aaron, I don't see any mention of this in D44406 - so it might have been good to have a separate review for this (or included this in the review of D44406, which I think is possible with the monorepo). Specifically - this change is missing test coverage (there should be a clang test that goes from C++ source code to LLVM IR & demonstrates the flag being emitted into the IR, etc). Also - what's the reason the non-triviality can't be implied by the absence of the trivial flag? (or the other way around) - the flags seem redundant with one another.
