[llvm-dev] How to help improve debug experience w/ optimizations enabled?

[Robinson, Paul via llvm-dev]

Hello Pierre,

We have certainly tried to make bug 38768 the umbrella for all the various poor experiences.  If other projects have poor debugging experiences when using clang, they should be reporting them here; otherwise we won't know about them.
You could also look at bug 37953 (https://bugs.llvm.org/show_bug.cgi?id=37953) which is an umbrella for bugs where we seem to lose track of debug info, although these do not necessarily lead to poor debugging experiences.  They are generally simpler, and would be a better choice for getting started with the LLVM project.  I'd suggest starting with one or two of these before getting into the tougher problems under bug 38768.

Welcome to one of the nicer open-source communities around, and if you get stuck we can usually provide some help to get you going again.

Hello,

I'd like to help improve the debug experience in LLVM/Clang when optimizations are enabled, but I'm not sure where to 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 experience, where should I look at?
e.g. bug trackers for clang-built projects, particular code examples, issues you encountered but haven't reported yet, etc.

Thank you.

Kind regards,
Pierre van Houtryve
