Hi Naresh, Thanks for the report.

I think in general for the kselftests, these aren't really regressions; we've simply not spent the time to sit down and get them all building.

That said, we should.

Since this isn't a recent regression, would you mind instead of emailing the list instead file an individual issue at our issue tracker per diagnostic identified?

https://github.com/ClangBuiltLinux/linux/issues

We are very active in tracking the progress on issues there. I would love for you and the LKFT team to participate with us there.

https://github.com/ClangBuiltLinux/linux/issues/1698 is the meta issue tracking the kselftest targets.

When we have a target building that regresses, then we should notify the list, but until then I think it may be less noisy to get issues on file.

Steps to reproduce:

• https://storage.tuxsuite.com/public/linaro/lkft/builds/2UHhSg0TPLhjp9Uq9EFce...

tuxmake --runtime podman --target-arch x86_64 --toolchain clang-17 --kconfig https://storage.tuxsuite.com/public/linaro/lkft/builds/2UHhSg0TPLhjp9Uq9EFce... LLVM=1 LLVM_IAS=1 debugkernel cpupower headers kernel kselftest modules

Any chance you can extract the invocation of `make` from the above for the bug reports? I'm guessing

`make LLVM=1 debugkernel cpupower headers kernel kselftest`? (LLVM_IAS=1 should be obsolete on mainline)
