r? @oli-obk (rustbot has picked a reviewer for you, use r? to override) |
So far I have a failing test (apologies for triggering a CI run). I'm still looking into how to get it passing. Any tips would be appreciated. To run the new test:

If you have concrete questions, ask them on Zulip in the help stream (or PM me there as a last resort, though note that I've been hacking on the compiler for merely one year) |

Thanks for the tips.
I started by just poking around and figuring out the simplest (but potentially naive) way to get the test passing.
I can try to take a look at the tips about the expect PRs and MultiSpan
to see if I can figure out a better way to solve the problem.
Or if this way is good then I'm happy to rebase into a single commit and land as is.

You patch does not compile. Could you fix it and push again? |
I haven't finished addressing your feedback yet. I was planning to work on this within the next week or two. This is my first contribution so please let me know if this delay is a problem or if you have any other feedback around how I should approach this patch. |
There is no rush. I was just getting on this PR. I saw some good progress, but I did not know what to do of it as CI fails. |
Update: I have the ui test passing locally. Just need to add an incremental test. Then I'll push and use |

Seems like it would be nice if it was possible to add revisions: rpass1
to a UI test so that we don't have to duplicate tests like this one across tests/incremetal
and tests/ui
.
First, is there already a good way to avoid this duplication?
If not, would being able to drive an incremental test from a UI test be undesirable for some reason?
If desirable, I'd be interesting in adding support for using the revisions: rpass1
annotation in a UI test. Do you have any tips on how I might best explore that (in a separate PR)?

This warn_multiple_dead_codes
method seems like it would be a fairly cold code path (as in, you'd have to have a project with a lot of dead code to hit this method a lot), so it seemed fine to add another loop here.

All feedback addressed. Thank you for the guidance. The PR guide doesn't mention anything about rebasing my commits https://rustc-dev-guide.rust-lang.org/contributing.html#opening-a-pr. I was planning to rebase into a single commit after this PR was approved. Let me know if that's unnecessary. @rustbot ready |
