Thank you for submitting a Pull Request (PR) to the LLVM Project!

This PR will be automatically labeled and the relevant teams will be
notified.

If you wish to, you can add reviewers by using the "Reviewers" section on this page.

If this is not working for you, it is probably because you do not have write
permissions for the repository. In which case you can instead tag reviewers by

If you have received no comments on your PR for a week, you can request a review
by "ping"ing the PR by adding a comment “Ping”. The common courtesy "ping" rate
is once a week. Please remember that you are asking for valuable time from other developers.

If you have further questions, they may be answered by the LLVM GitHub User Guide.

You can also ask questions in a comment on this PR, on the LLVM Discord or on the forums.

[adibiagio]

Could you please simplify this run line?
We don't need to test all-stats and all-views. I'd like this test to only show the bottleneck analysis output and not the timeline or the resource pressure.

[FlameTop]

Removed non-bottleneck views

[mshockwave]

nit: would it be better to use llvm::json::OStream (link) here rather than storing serialized json objects/array?

[FlameTop]

Apologies for the delay in replying.

I'm afraid a re-factor of how MCA does json serialisation is beyond the resources I have been permmited to allocate to this task. This change does follow the conventions used for other json writing in MCA.

[github-actions]

✅ With the latest revision this PR passed the C/C++ code formatter.

[adibiagio]

Have you looked at whether test failures reported by
buildkite/github-pull-requests (https://buildkite.com/llvm-project/github-pull-requests/builds/65010 )are genuine ?

The following tests fail after your change:

   LLVM :: tools/llvm-mca/JSON/X86/views-custom-parameters.s
   LLVM :: tools/llvm-mca/JSON/X86/views-multiple-anonymous-regions.s
   LLVM :: tools/llvm-mca/JSON/X86/views-multiple-region.s
   LLVM :: tools/llvm-mca/JSON/X86/views.s

I wonder if some of the CHECK-NEXT should be re-generated after your change.

[FlameTop]

Hmm, no I didn’t see them. I will check if they are real etc. Thanks Phil From: Andrea Di Biagio ***@***.***> Sent: Friday, August 9, 2024 4:13 PM To: llvm/llvm-project ***@***.***> Cc: Camp, Phil ***@***.***>; Author ***@***.***> Subject: Re: [llvm/llvm-project] [llvm-mca] Add bottle-neck analysis to JSON output.

[adibiagio]

I was able to reproduce those same failures on my linux machine.

Please make sure to run all mca lit tests after every change.

In this case, tests needs to be re-generated. You can easily regenerate those files by using the update_mca_test_checks.py script found in llvm/utils/.

For example, on my machine I was running the following command:

> ~/llvm-project/llvm/utils/update_mca_test_checks.py --llvm-mca-binary ~/llvm-project/debug-build/bin/llvm-mca ~/llvm-project/llvm/test/tools/llvm-mca/JSON/X86/*.s

You need to specify the location of your llvm-mca binary, and which files to update.

I hope it helps
-Andrea

[FlameTop]

Thank you @adibiagio for instructions. I have re-generated and pushed the updated tests.

[adibiagio]

LGTM thanks!

[github-actions]

@FlameTop Congratulations on having your first Pull Request (PR) merged into the LLVM Project!

Your changes will be combined with recent changes from other authors, then tested
by our build bots. If there is a problem with a build, you may receive a report in an email or a comment on this PR.

Please check whether problems have been caused by your change specifically, as
the builds can include changes from many authors. It is not uncommon for your
change to be included in a build that fails due to someone else's changes, or
infrastructure issues.

How to do this, and the rest of the post-merge process, is covered in detail here.

If your change does cause a problem, it may be reverted, or you can revert it yourself.
This is a normal part of LLVM development. You can fix your changes and open a new PR to merge them again.

If you don't get any reports, no action is required from you. Your changes are working as expected, well done!
