Ignore test files on powerpc64* that's already ignored on powerpc

[infinity0]

Fixes #50989.

The ignore-checker was made more strict recently so we now need more explicit ones

Thanks for the PR!

Doing a spot check with rg --files-without-match ignore-powerpc64 $(rg --files-with-matches 'ignore-powerpc'), I see these files:

src/test/codegen/stack-probes.rs
src/test/ui/asm-out-assign-imm.rs

It seems this PR is missing a few of those, should it have them?

[glaubitz]

I don't think that any of the changes here should make the CI tests fail. Are you sure this isn't a different problem? Can someone retry?

[shepmaster]

We can retry when the review comments are addressed - no need to waste CI time until then.

[shepmaster]

However, if you read the messages, they are because the locations of error messages have changed in the modified files, so yes, this PR has broken those tests.

[glaubitz]

Sorry, I must be missing something here? All that @infinity0 did was adding some // ignore-powerpc64 to tests which fails on powerpc64*. Is there anything else that needs to be added?

[shepmaster]

the locations of error messages have changed in the modified files

I might have misread, let me investigate more.

[shepmaster]

The same error occurs when I run make check locally with this PR.

[glaubitz]

Hmm, ok. So, I assume this means adding // ignore-bla involves also modifying some other part to reflect those changes?

[glaubitz]

I am trying to understand the problem and just looked at other commits which set certain tests to ignore for mips*, i.e. 54467ae. And I don't anything different to what @infinity0 has done.

Has anything changed in this regard?

[infinity0]

I will fix the line numbers tomorrow but I am not sure blanket-ignoring the other files is appropriate, since they didn't cause test failures that I could see.

As an aside I'm pretty annoyed that I even have to do this (and then getting told to do extra work on the PR to fix it), the original person who made this change really should be the one fixing it.

[glaubitz]

@infinity0 Fixing the .stderr files helps, see: #51343.

[glaubitz]

@infinity0 You can close this now, my fix in #51343 was merged.

[infinity0]

Your PR was merged but it only takes care of sparc64 not powerpc64, sounds like this PR is still needed (and the line numbers need fixing up again?)

[infinity0]

I just saw #51392 so closing.
