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

This is a false positive. We're currently moving our CI jobs to another
machine (of a different kind, even) and the reference build ran on the
new machine while the build with the patches ran on the old one. Sorry
for the noise.

This is a false positive. We're currently moving our CI jobs to another
machine (of a different kind, even) and the reference build ran on the
new machine while the build with the patches ran on the old one. The
same happened with the other patch about which we notified you today.

Hi Nathan,
Sorry this report is incorrect because we are in the process of moving

Please ignore it.

It appears that this build was running tests on qemu that doesn't seem to support
the same signal handling behaviour for SME as would the kernel that supports SME.
On a system that supports SME with kernel 6.16 these tests work as expected provided
that their dependencies are resolved by dynamic loader to the new version of libgcc.
So, no issue in the patch or in the tests.
Thanks,
Yury

Is it expected that I'm not able to log into the Jira instance, and that
most of the links in there are either:
| Secure Connection Failed
|
| An error occurred during a connection to git-us.linaro.org. Cannot communicate securely with peer: no common encryption algorithm(s).
..., or:
| Oops!
|

I should have a fix: the attached
"Adjust 'libgomp.c++/target-cdtor-{1,2}.C' for 'targetm.cxx.use_aeabi_atexit' [PR119853, PR119854]"
ought to address this. I've "mock-tested" this locally; is there a way
for me to run this through the Linaro "pre-commit" CI?

Tomasz,
The new __any_input_iterator type should only be declared for C++20
and higher, so guarded by __cpp_lib_concepts
Just checking __cpp_concepts isn't enough, because that's true for
-std=c++17 -fconcepts but std::input_iterator isn't defined in that
case.
