Dear Linaro Community,
I am looking for advice on how to reproduce a flang-arm64-windows-msvc LLVM build bot failure (hopefully I ended up in the right place here).
I had to revert an LLVM PR (https://github.com/llvm/llvm-project/pull/150783) that broke the flang-arm64-windows-msvc LLVM buildbot yesterday due to some tablegen-related problem. I did prepare a reland PR (https://github.com/llvm/llvm-project/pull/151125) that addresses a potential issue. However, since I did not see any other buildbot failures and since I was not able to reproduce the problem locally, I wonder if there is a way to run the flang-arm64-windows-msvc buildbot on my reland PR? Alternatively, hints on how to reproduce the problem locally on a x86 Linux machine would be appreciated.
Best, Tobias

LLVM build bot failure (hopefully I ended up in the right place here).
You did.
that broke the flang-arm64-windows-msvc LLVM buildbot yesterday due to
some tablegen-related problem.
Thank you for reacting quickly and following up.
However, since I did not see any other buildbot failures and since I was
not able to reproduce the problem locally, I wonder if there is a way to run the flang-arm64-windows-msvc buildbot on my reland PR?
No. I wish there was a better answer and maybe there will be in future as llvm testing expands. For now, the pre-commit PR world and the post-commit world are separate.
Alternatively, hints on how to reproduce the problem locally on a x86
Linux machine would be appreciated.
@Carlos Seo carlos.seo@linaro.org was minding our bots yesterday, but I think handed over to @Omair Javaid omair.javaid@linaro.org today. One of the two will reproduce the issue and assist you.
Carlos, Omair, I think Tobias is specifically referring to https://github.com/llvm/llvm-project/pull/150783#issuecomment-3131154498.
Thanks, David Spickett.

That would be great.

Yes this is the pull request I reverted.
I prepared a reland commit here:
https://github.com/llvm/llvm-project/pull/151125
It contains a small tablegen change that may address the issue (but it would be great to double check if this is indeed the case).

I have just initiated a local build with your reland commit included, once it runs to completion I will update you with the result.

Hi Omair, David
Unfortunately the problem seems to persist:
https://lab.llvm.org/buildbot/#/builders/207/builds/4525
Could it be that build bot has some state that could cause this problem? Especially since the PR seems to work in isolation.
Hi Tobias,
My Windows test machine is busy building LLVM release, but I will try to test this as soon as possible.
I appreciate your patience.
Thanks! -- Omair Javaid www.linaro.org
