Re: [Linaro-TCWG-CI] llvmorg-24-init-14147-g4149fd77e859: 1 regression on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, This test is incorrect. 0196_0003.c contains intentional undefined behavior and should not be used as a runtime correctness test. The observed SIGSEGV is a valid consequence of the program's undefined behavior, and the test should be converted to a compile-only test to avoid environment-dependent failures. Please ignore the mail. We'll update the test. We apologize for the false detection. Best regards, Yasuyuki Ohno Software Development Div., Advanced Technology Development Unit, Fujitsu Research, Fujitsu Limited, JAPAN. ________________________________ 差出人: ci_notify(a)linaro.org <ci_notify(a)linaro.org> 送信日時: 2026年10月16日 19:37 宛先: contact-ci-compiler-test-suite(a)cs.jp.fujitsu.com <contact-ci-compiler-test-suite(a)cs.jp.fujitsu.com> CC: maxim.kuvyrkov(a)linaro.org <maxim.kuvyrkov(a)linaro.org>; cullen.rhodes(a)arm.com <cullen.rhodes(a)arm.com> 件名: [Linaro-TCWG-CI] llvmorg-24-init-14147-g4149fd77e859: 1 regression on aarch64 Dear contributor, Our automatic CI has detected problems related to your patch(es).

Your LLVM Buidbot / Buildkite machines need to update their cmake version

by David Spickett

Hello TCWG, LLVM is preparing to bump the minimum cmake version - https://github.com/llvm/llvm-project/pull/223854 to 3.31. Please could you update the version in your bot image(s)? On the PR Mehdi is asking about buildkite libcxx, but if you update the cmake version for the buildbot images, it will apply to buildkite and buildbot so you will be ready for when the PR lands. I don't know if there is any upper limit on the version, but if you're building it from source anyway I'd match 3.31 exactly and save yourself some hassle. Thanks, David Spickett.

Re: [Linaro-TCWG-CI] llvmorg-24-init-10518-g053331c2c9f4: 1 regression 5 fixes on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, This test is incorrect. In the program (Fujitsu/Fortran/0632/Fujitsu-Fortran-0632_0000.test), the execution result differs from the expected result when compiled with -ffast-math. Investigation showed that the failure is related to the REAL MOD optimization enabled by -ffast-math. Disabling the REAL MOD optimization with -fno-fast-real-mod avoids the issue: Please ignore the mail. We'll update the test. We apologize for the false detection.

These are not regressions from the patch: the three tests are new in it, and on this configuration every coarray test linked with -lcaf_shmem fails at execution, so each newly added one shows up in the regression delta. libcaf_shmem starts the images by fork () + execve (argv[0], ...) of the test executable. Your harness starts the test through qemu-wrapper.sh, which passes -L <sysroot> to qemu, but the re-executed images are dispatched by binfmt_misc (arm-binfmt-P) without the sysroot, cannot find the dynamic loader and exit with status 255. The gfortran.log should show "arm-binfmt-P: Could not open '/lib/ld-linux-armhf.so.3'" followed by "ERROR: Image N failed with signal 0, exitstatus 255" for all images. Exporting QEMU_LD_PREFIX=<sysroot> in the test environment (in addition to -L) should fix all of the caf_shmem execution tests; the environment is passed on to the images. The same happens on your aarch64 cross configuration. Regards, Jerry

Re: [Linaro-TCWG-CI] gcc patch #142437: 2 regressions on aarch64

by Lunex

Hi, thanks for the report. I looked into this and I dont think my patch is actually responsible for these failures. The gcov-39.c prime-paths test seems to be a pre-existing flaky test rather than something introduced by my changes — my patch only touches the tree optimization path (final value replacement logic) and has no interaction with gcov instrumentation or path coverage counting. Could someone check if this failure shows up in the baseline as well? Happy to dig deeper if needed, but from what I can see this looks unrelated to my patch. Thanks --------- Lunex<imlunex2011(a)gmail.com>

I have a hunch gcc.misc-tests/gcov-39.c is flaky, if not generally then at least in the context of your CI.

Hello Linaro CI Team, This looks unrelated to the patch. It only defines LINK_SSP_SPEC inside the DEFAULT_LIBC == LIBC_MUSL block of gcc/config/linux.h plus two rs6000 headers, so nothing from it is compiled into an aarch64-linux-gnu build. To be sure I built aarch64-linux-gnu cross compilers from master with and without the patch using the same configure flags as this CI, and xgcc -dumpspecs output is byte-identical, while the same tree targeted at aarch64-linux-musl does show the new -lssp_nonshared spec. The failing test is a gcov prime-paths count, and the build's own results.compare.txt says "No regression found in 3 common sum files". Happy to dig further if anyone sees a connection I am missing. Thanks, Sunil Dora ________________________________ From: ci_notify(a)linaro.org <ci_notify(a)linaro.org> Sent: Tuesday, September 1, 2026 10:48 AM To: Dora, Sunil Kumar <SunilKumar.Dora(a)windriver.com> Cc: raj.khem(a)gmail.com <raj.khem(a)gmail.com> Subject: [Linaro-TCWG-CI] gcc patch #142457: 2 regressions on aarch64 CAUTION: This email comes from a non Wind River email account!
