The bors queue has a spurious failure (30 min timeout which is likely related to 9696), but the CI PR reported in #55532 (comment) looks legit, so I'm not going to retry.

pnkfelix · 2018-11-07T10:57:20Z

That is very goofy. I do not see that test result locally (when testing stage1). Is there any chance that our diagnostic here is behaving differently on different platforms...? (or that the behavior somehow differs between stage1 and stage2 here...?)

Update: No, stage2 works fine locally.

pnkfelix · 2018-11-07T10:58:24Z

(isn't it also weird that the travis result says this:

[00:50:27] failures:
[00:50:27]     [ui] ui/lint/lint-type-overflow2.rs
[00:50:27]     [ui] ui/lint/lint-type-overflow2.rs

Why is that occurring twice?

pnkfelix · 2018-11-07T10:59:40Z

Oh, the raw log has it only once.

So that's something wrong with some other piece of post-processing, I guess

This test specifically notes that it does not want to invoke the linker, due to the way it (IMO weakly) exercises the `#[link=...]` attribute. In any case, removing the the `#[rustc_error]` here uncovered an "invalid windows subsystem" error that was previously not included in the transcript of diagnostic output. So that's a step forward, (right?).

I also added `// skip-codegen` to each one, to address potential concerns that this change would otherwise slow down our test suite spending time generating code for files that are really just meant to be checks of compiler diagnostics. (However, I will say: My preference is to not use `// skip-codegen` if one can avoid it. We can use all the testing of how we drive LLVM that we can get...) (Updated post rebase.)

pnkfelix · 2018-11-07T14:07:55Z

okay ... at this point I assume this must be some weird artifact of my own environment, maybe some customization in my config.toml. Looking.

pnkfelix · 2018-11-07T14:09:27Z

(ah it might be due to an optimize-tests = false in my config.toml...

pnkfelix · 2018-11-07T14:15:55Z

Yes, okay, the presence/absence of -O causes the lint output to differ here.

oli-obk · 2018-11-07T14:33:59Z

I usually add // compile-flags: -O to such tests, so that optimize-tests does not change the behavior`

…rom `rustc -O`. (The fact that output differs under `opt-level=0` is an instance of rust-lang#55757.)

… `-O`.
