...rogram. While we're only proposing using Dexter as a replacement debuginfo-tests driver, we think there's a future in being able to measure ``how bad'' both debuginfo and codegen changes affect the debugging experience. More about that in a future RFC though!

...start. I've seen the umbrella bug for poor debug experiences (38768 https://bugs.llvm.org/show_bug.cgi?id=38768 ). Is there any bug in this list that isn't being looked at (and that doesn't require a lot of knowledge) that I could work on? I also tried using Dexter (https://github.com/SNSystems/dexter ) to find issues, but it's hard to find something that I can fix in a reasonable amount of time using Dexter alone as I don't have enough LLVM experience to know where to look at/what to look for. In general, if I want to find bug reports about missing debug info/poor debug experien...

...elp us design around it. Note that the current Dexter codebase is going to be significantly remangled, we're trying to decouple the expected-behaviour language from the debugger-abstractions summary of how the program behaved.

...as I don't have a good infrastructure set up for that. Overall, my impression is that GlobalISel is ready to be enabled by default for AArch64 at -O0, if others also believe it's ready. Thanks, Kristof Detailed observations: 1. Debug info analysis with DIVA<https://github.com/SNSystems/DIVA/blob/master/linux/doc/DIVA_user_guide.pdf>: I used DIVA options "-a --show-generated --show-level --show-location" to dump and diff debug info differences for the test-suite for "-O0 -g" comparing GlobalISel with non-GlobalISel.

Good point, too. I believe I can find lines starting with `@parameter` and apply the same name conversion rules to identifiers after `@parameter`. Since lld doesn't use doxygen comments, it is fine for now, but before moving forward, I'll address that. Thank you for pointing that out.
