Very strange... that was supposed to have been fixed by #116814. Let's try it without the assertion and with some debug logging. At least, apple does pass!

Thank you for the PR. I have some concerns about dump-ice-to-disk regarding test parity and a question about a FIXME in panic_abort-eh_frame.

I restored the ignore on this specific platform, let me know if that is adequate.

jieyouxu

Thank you, the other changes look good, but the ignore on the panic-abort test is a bit interesting, I'll wait for people who are more familiar to see if it's intentional that it fails on i686-pc-windows-gnu.

jieyouxu · 2024-07-22T17:19:45Z

tests/run-make/panic-abort-eh_frame/rmake.rs

+//@ ignore-i686-pc-windows-gnu
+// Reason: the DW_CFA symbol appears on this specific architecture


Question: cc @Nilstrieb (since you were the reviewer of #112403) and @saethlin, since I lack context for this test: is it intentional that this property is only preserved for linux, but not necessarily for i686-pc-windows-gnu, or is this a bug? The original test was only-linux but I couldn't find reasons for why it had to be only-linux other than it was impacting RfL so obviously we would want to test it on linux.

The context is that everything under -Zub-checks creates non-unwinding panics, so it is a problem for RFL and quite goofy in general if enabling -Zub-checks produces new sections which are only for unwinding.

I don't know enough about this target to say whether it has this section with UB checks disabled. If it has this section with UB checks off that seems like a separate bug, we can handle that in another issue. If it gains this section when UB checks are enabled on this target specifically I would really like to know why.

Actually this is intended behavior that uwtable is forced on Windows (cf. #128136 (comment)), see

rust/compiler/rustc_target/src/spec/base/windows_msvc.rs

Line 19 in d24930c

requires_uwtable: true,

Can you revert this to //@ only-linux and add a comment to that effect?

Sounds good to me!

Oneirical · 2024-07-24T13:55:27Z

Thanks, r=me after a rebase + adding the FIXME linking to #128136.

There's something weird about this. The uwtable forcing file is named windows_msvc.rs, and the test does pass on MSVC (see https://github.com/rust-lang-ci/rust/actions/runs/10017286801/job/27691281649, it's not even getting ignored). It even passes on x86 gnu-windows. It is only this one specific architecture (i686-mingw) that fails.

Given this, why would only-linux be superior to the current ignore?

jieyouxu · 2024-07-25T11:25:21Z

Let's keep it only-linux and just document that currently uwtables are forced on windows targers (apparently they're eventually forced even on windows-gnu). AFAICT we only are trying to guarantee this property on linux, but not for Windows.
