gollvm: golang.org/x/mod/semver package is not compiling on Ubuntu 20.04 (Github Actions) #42843

Hi. All jobs for https://github.com/advancedwebdeveloper/clang_test_cpu_features/runs/1446453097 failed. Here is what I see here:

That's coming from Clang 11.

ianlancetaylor commented 3 years ago

I can build the package with gccgo using go build.

I'm not sure how to interpret that output but it looks like a middle-end bug.

advancedwebdeveloper commented 3 years ago

My workflow (Github Actions) could be modified, to trace anything that you would require. Request anything you want - or try to modify the YAML file, within your own repo. That could allow to reproduce/check some fault scenarios.

@ianlancetaylor , you didn't explain what should I trace/log. Anything that I should check, ahead of @thanm's investigation?

ianlancetaylor commented 3 years ago

I'm sorry, I don't know.

thanm commented 3 years ago

Is this a problem only with the Release cmake target? Or do you also see it with DCMAKE_BUILD_TYPE=RelWithDebInfo?

advancedwebdeveloper commented 3 years ago

It might no more be reproducible/no issue present - some errors of another kind are observable, during https://github.com/advancedwebdeveloper/clang_test_cpu_features/actions/runs/395799034

As you can observe in the logs - I caught these errors, while using Clang 9:

. There is a bug, with GCC:

. I got the very same bug, as I caught with Clang 9, while using Clang 10:

And the same bug is present with Clang 11, too.

thanm commented 3 years ago

OK, that looks a bit more actionable. I'll send a patch later this morning for the build problem.

For the original issue (crash in Combine redundant instructions) I am able to reproduce that as well, will need to take a closer look.

Yes, your patch resolved the last issue. I tried to re-run the workflow - and (as you can see) various packages are not compiled. I am unsure what should be logged.

thanm commented 3 years ago

I just submitted 29d8ea6cf9e08a51f89d72dbeca6c0aed4c2016a, that should resolve the llvm-goc runtime error.

You can investigate the log for GCC oriented build https://github.com/advancedwebdeveloper/clang_test_cpu_features/commit/e8a830d4c248db0961e0f57f9d61e032efd1cb15/checks/1491324454/logs - it looks like the compilation process itself crashes:

@thanm, which verbosity options should be enabled? I am not familiar with GCC, really.

advancedwebdeveloper commented 3 years ago

I am confirming that go.googlesource.com/gollvm/+/29d8ea6cf9e08a51f89d72dbeca6c0aed4c2016a allowed to build gollvm with Clang 10: https://github.com/advancedwebdeveloper/clang_test_cpu_features/runs/1491324386?check_suite_focus=true . Same for Clang 11: https://github.com/advancedwebdeveloper/clang_test_cpu_features/runs/1491324420?check_suite_focus=true . Everybody dance now :)

advancedwebdeveloper commented 3 years ago

I just tried to build for "release" - and I didn't get that issue, with GCC, any more: https://github.com/advancedwebdeveloper/clang_test_cpu_features/runs/1491760391?check_suite_focus=true . All tests passed successfully. Clang 10 and Clang 11 built gollvm successfully, as before.

Not sure if it makes sense to support Clang 9.

Thanks for assisting/patching. Closing this.
