1. Good for you.
2. Ignore the haters in the comments.
> my latest PR is my second-ever to LLVM and is an entire linter check.
That is so awesome.
> The code is of terrible quality and I am at 100+ comments on my latest PR.
The LLVM reviewers are big kids. They know how to ignore a PR if they don't want to review it. Don't feel bad about wasting people's time. They'll let you know.
You might be surprised how many PRs even pre-LLMs had 100+ comments. There's a lot to learn. You clearly want to learn, so you'll get there and will soon be offering a net-positive contribution to this community (or the next one you join), if you aren't already.
Best of luck on your journey.
