As always, thanks for the report. This is an LLVM regression/change in behavior caused by [1], which can break as-option and as-instr on releases prior to commit d5c8d6e0fa61 ("kbuild: Update assembler calls to use proper flags and language target"), as unsupported flags for the current target ('-x') may be present (KBUILD_CFLAGS is used for these tests instead of KBUILD_AFLAGS). Inside try-run, the macro behind as-instr and as-option, I see

clang-17: error: unsupported option '-mno-prefixed' for target 'powerpc64le-linux-gnu' clang-17: error: unsupported option '-mno-pcrel' for target 'powerpc64le-linux-gnu' clang-17: error: unsupported option '-mno-altivec' for target 'powerpc64le-linux-gnu' clang-17: error: unsupported option '-mno-vsx' for target 'powerpc64le-linux-gnu' clang-17: error: unsupported option '-mno-mma' for target 'powerpc64le-linux-gnu' clang-17: error: unsupported option '-mno-spe' for target 'powerpc64le-linux-gnu'

This has come up recently elsewhere in PowerPC, see commit 2b694fc96fe3 ("powerpc/boot: Disable power10 features after BOOTAFLAGS assignment"). While I think it is dubious that clang errors on these flags for the assembler target, this is already fixed on the Linux side by using KBUILD_AFLAGS for these make macros.

I am preparing a series of d5c8d6e0fa61 and its dependencies for 6.1 but I want to do sufficient build testing first, which is currently running for me. Would you be able to point your matrix to [2] to make sure everything works properly with both GCC and LLVM? It is a work in progress as the second patch in the stack needs a proper commit message but it is the diff I expect to ship so that it all that matters.

We'll start building [2] with GCC and LLVM by using tuxplans and get back to you.

LKFT has been configured to run GCC and LLVM in total 205 builds and all the builds have passed on your tree / branch [2]. You can find the list of builds including kselftest, perf, rcutorture, kunit, kmemleak and many more combinations and architectures.

I request you to review the list of builds results and test results on projects page [3] [4]. I do not find any regressions compared with mainline master as sanity testing.

Do you think LKFT should build your tree / branch often ? We are happy to test anytime.

Thanks Daniel and Anders for your work.

build_names: that got tested and all have passed.
