The powerpc allnoconfig failed with gcc-8 but passed with gcc-12.
Build regression: powerpc: allnoconfig: gcc-8: Inconsistent kallsyms data
Reported-by: Linux Kernel Functional Testing lkft@linaro.org
### Build error Powerpc Inconsistent kallsyms data Try make KALLSYMS_EXTRA_PASS=1 as a workaround make[1]: *** [Makefile:1244: vmlinux] Error 1
### Commit pointing to, Makefile.compiler: replace cc-ifversion with compiler-specific macros commit 88b61e3bff93f99712718db785b4aa0c1165f35c upstream.
### Build
- https://storage.tuxsuite.com/public/linaro/lkft/builds/36OCnVeYGpKUCXtxVdz6g...
- https://storage.tuxsuite.com/public/linaro/lkft/builds/36OCnVeYGpKUCXtxVdz6g...
### Steps to reproduce
- tuxmake --runtime podman --target-arch powerpc --toolchain gcc-8
--kconfig allnoconfig
Odd, this works on 5.10 ok? What is different about 5.15 that keeps this from working?
This issue does reproduce for me locally but only with gcc-8 from TuxMake (i.e., a version from Debian), not with GCC 8.5.0 from kernel.org.
$ git show -s --pretty=kernel 869807d760ee ("libbpf: Fix invalid return address register in s390")
$ tuxmake -r podman -a powerpc -t gcc-8 -k allnoconfig default ... Inconsistent kallsyms data Try make KALLSYMS_EXTRA_PASS=1 as a workaround ...
However, reverting the backport of 88b61e3bff93 ("Makefile.compiler: replace cc-ifversion with compiler-specific macros") does not resolve the issue for me:
$ git revert --no-edit c8dad7eb1e6221e0363ee468dc46700bfbad6dd2 [detached HEAD 1669da6455e4] Revert "Makefile.compiler: replace cc-ifversion with compiler-specific macros" Date: Fri Dec 5 10:30:10 2025 -0700 13 files changed, 30 insertions(+), 37 deletions(-)
$ tuxmake -r podman -a powerpc -t gcc-8 -k allnoconfig default ... Inconsistent kallsyms data Try make KALLSYMS_EXTRA_PASS=1 as a workaround ...
My bisect landed on the backport of 19de03b312d6 ("block: make REQ_OP_ZONE_OPEN a write operation") and reverting that actually resolves the error.

No idea why that commit would cause such an issue... but it does not appear to be 88b61e3bff93 so I guess I am off the hook ;)
Great, thanks for looking into this and the information. I'll leave your patch in :)
