Re: [Linaro-TCWG-CI] llvmorg-24-init-16172-g9cf173d541d9: 111715 regressions on aarch64

by Laurent Alfonsi

The option *-aarch64-enable-pipeliner* is no more supported. Looking at the commit, it seems to be accessible now with the option *-enable-pipeliner*. I am making the replacement on the CI side.

Re: [Linaro-TCWG-CI] llvmorg-24-init-15115-g63f066025063: 5 regressions on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, These tests are incorrect. Therefore, we will correct the tests. Several Fujitsu Fortran tests fail during result comparison because their floating-point tolerances are too strict for single-precision arithmetic. For four of these tests, fpcmp-target uses a relative tolerance of 0x1.0p-51, which corresponds to double-precision accuracy and is too strict for the single-precision computations performed by the tests. The remaining test, 0676_0115, performs its own error check, but its absolute tolerance is also too strict for the observed single-precision result. Please ignore the mail. We apologize for the false detection.

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.

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>

Please find some details below.

I have a hunch gcc.misc-tests/gcov-39.c is flaky, if not generally then at least in the context of your CI. I suggest you consider filtering out that test until your human resources has investigated the flakiness. > Used configuration : > *CI config* tcwg_gcc_check aarch64-linux-gnu > *configure and test flags:* none, autodetected on aarch64-unknown-linux-gnu--disable-multilib --enable-fix-cortex-a53-835769 --enable-fix-cortex-a53-843419 --with-arch=armv8-a > > If you have any questions regarding this report, please ask on linaro-toolchain(a)lists.linaro.org mailing list. > > -----------------8<--------------------------8<--------------------------8<-------------------------- > > The information below contains the details of the failures, and the ways to reproduce a debug environment: > > You can find the failure logs in *.log.1.xz files in > * http://54.172.246.49:9090/jobs/tcwg_gcc_check--master-aarch64-precommit/bui… > The full lists of regressions and improvements as well as configure and make commands are in > * http://54.172.246.49:9090/jobs/tcwg_gcc_check--master-aarch64-precommit/bui… > The list of [ignored] baseline and flaky failures are in > * http://54.172.246.49:9090/jobs/tcwg_gcc_check--master-aarch64-precommit/bui… > > Current build : http://54.172.246.49:9090/jobs/tcwg_gcc_check--master-aarch64-precommit/bui… > Reference build : http://54.172.246.49:9090/jobs/tcwg_gcc_check--master-aarch64-build/builds/… > > Warning: we do not enable maintainer-mode nor automatically update > generated files, which may lead to failures if the patch modifies the > master files. brgds, H-P
