Re: [Linaro-TCWG-CI] llvmorg-23-init-20756-gd445267fbb56: 2 regressions on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, The tests are incorrect. The causes are as follows. The test programs perform an exact comparison of a single-precision floating-point result. Because it is compiled with -msve-vector-bits=scalable, the generated code adapts to the SVE vector length of the execution environment. As a result, the composition of partial sums and the order of floating-point additions vary between systems, producing different rounding results. The tests failed because it did not allow normal floating-point rounding differences caused by vectorized execution and compared the result against specific values using exact equality. Please ignore the mail. We'll update the tests. 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: 2026 年 7 月 14 日 (火曜日) 9:53 宛先: contact-ci-compiler-test-suite(a)cs.jp.fujitsu.com <contact-ci-compiler-test-suite(a)cs.jp.fujitsu.com> Cc: david.green(a)arm.com <david.green(a)arm.com>; maxim.kuvyrkov(a)linaro.org <maxim.kuvyrkov(a)linaro.org> 件名: [Linaro-TCWG-CI] llvmorg-23-init-20756-gd445267fbb56: 2 regressions on aarch64 Dear contributor, Our automatic CI has detected problems related to your patch(es).

Fwd: [Linaro-TCWG-CI] gcc patch #138844: Failure on arm

by jeevitha

Hi All, The changes in this patch are limited to the rs6000 backend and only introduce a new machine mode (`TDOmode`) with corresponding rs6000-specific handling. Since the changes are target-specific, I'm not sure why they would cause a bootstrap failure on the ARM configuration. Could this be an unrelated or flaky CI failure? For context, the other CI results for this patch are: https://patchwork.sourceware.org/project/gcc/patch/993e1e61-3bb4-4d74-b507-… * `linaro-tcwg-bot/tcwg_simplebootstrap_build--master-arm-bootstrap`: **Failed** * `linaro-tcwg-bot/tcwg_gcc_build--master-aarch64`: **Passed** * `linaro-tcwg-bot/tcwg_gcc_build--master-arm`: **Passed** * `linaro-tcwg-bot/tcwg_simplebootstrap_build--master-aarch64-bootstrap`: **Passed** Thanks, Jeevitha -------- Forwarded Message -------- X-Mozilla-Status: 0001 X-Mozilla-Status2: 00000000 Return-Path: <ci_notify(a)linaro.org> Received: from ltc-imap-p9a.rchland.ibm.com ([unix socket]) by ltc-imap-p9a.rchland.ibm.com (Cyrus 3.0.7-28.el8_10 Fedora) with LMTPA;

Re: [Linaro-TCWG-CI] llvmorg-23-init-21388-g154834916515: 2 regressions on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, These tests are incorrect. Therefore, we will correct them. The lastprivate variables pa/pb did not meet OpenMP's requirements because they were treated as private instead of the required shared variable type. Please ignore the mail. We'll update the test.

Re: [Linaro-TCWG-CI] llvmorg-23-init-21399-gb1b919870974: 2 regressions on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, These tests are incorrect. Therefore, we will correct them. The test incorrectly uses statement function dummy argument names (e.g., a, b) that conflict with already declared array variables in the same scope. Please ignore the mail. We'll update the test. We apologize for the false detection.

by Yasuyuki Ohno (Fujitsu)

Hi, The test violates Fortran dummy argument aliasing rules. Overlapping elements (xx(6) and yy(1)) reference the same memory (x(6)), and the code performs both read and write through different dummy arguments, resulting in undefined behavior. Please ignore the mail. We'll update the test. We apologize for the false detection.

How can any patch to the Fortran front end (much less a completely trivial one) affect libcommon.a? If that file was truncated maybe it was a transient disk-full or file system error? -Sandra

Re: [Linaro-TCWG-CI] llvmorg-23-init-19659-g3fee6e5ab45d: 18533 regressions on aarch64

by Michael Kruse

I think this is a misattribution of the failure. #203481 is a change of the CMake build system, it does not change anything functional in the flang compiler. #203481 had a build problem which was fixed in #204438. But since Flang built successfully, it cannot be the problem of that CI problem. Michael Am Fr., 19.
