[DebugInfo] A value-tracking variable location update

How to help improve debug experience w/ optimizations enabled?
+ 1 to Paul’s suggestions. I’d add that if an open bug report isn’t assigned to anyone, you can assume it’s fair game. Feel free to assign a bug to yourself if you start working on it. To toss another idea out there, you might try picking a small .o and working backwards to figure out why location information in it is incorrect. This can reveal a different set of bugs compared to e.g. running

Why is lldb telling me "variable not available"?
...or register location). Wheras in the coroutine code you're generating the variable address doesn't get storage. If [0] is useful for you I can get that landed; it'd be good to hear whether this resolves the dbg.addr intrinsics not having an affect on the output.

[RFC] A value-tracking LiveDebugValues implementation
...: this path can lead, slowly, to there being no debug instructions for variable locations! And as described in my RFC sitrep-email, it can be more accurate than location only tracking too.

[RFC] Adopt Dexter and use it to run debuginfo-tests
...described are here [1]. We're also working on some sequencing commands ("this state is seen before that state") to better test optimized debuginfo. Proposal ------------ Our patch is up here: https://reviews.llvm.org/D68708 You can browse the tree on github here: https://github.com/jmorse/llvm-project/tree/dexter-rfc It imports Dexter into the debuginfo-tests repository, and converts many existing debuginfo-tests to run with Dexter. We'd suggest that future debuginfo integration tests use Dexter to run by default, so that we can build a testsuite ensuring clang/llvms debuginfo...

Why is lldb telling me "variable not available"?
Apologies for the slow response here Jeremy. Your reply has been incredibly helpful so far, I just need to try adding 'llvm.dbg.addr' myself to confirm that works.
