Re: [Linaro-TCWG-CI] llvmorg-23-init-15424-g3def12d2a418: 1 regression on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, With the https://github.com/llvm/llvm-project/commit/3def12d2a418f8e49f0b88ddf9070af… , the result of `ieee_support_rounding()` for `ieee_other` has been corrected so that `.false.` is now the correct value. This test expects `.true.`, but following the correction above, the correct result is now `.false.`. Therefore, this test is incorrect. I apologize for the false detection. We'll correct this test. It may take some time due to our internal release process, sorry.

Re: [Linaro-TCWG-CI] llvmorg-23-init-12953-g1348766d1d68: 1 regression on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, Probably these errors are false detections caused by precision errors in floating-point arithmetic. Please ignore the mail. We'll update the tests. I apologize for the false detection. Details are as follows. The primary purpose of this TP (https://github.com/fujitsu/compiler-test-suite/blob/main/Fortran/0683/0683_…) is to verify OpenMP SIMD reduction. However, since -fopenmp is not specified, !$omp simd is treated as a comment. Consequently, we are currently verifying the results of sequential calculations for single-precision complex numbers. In this TP, we determine whether the result is OK or NG by calculating the size of the complex difference in the accumulation results for single-precision complex numbers. Due to SLP vectorization, a difference arose in the accumulation results, and the difference between the calculated value and the expected value was 3 ULP in the real part and 5 ULP in the imaginary part. Consequently, the size of the complex difference is 5.8309517, which exceeds the threshold of 5.0, resulting in an NG. Since the difference is approximately 5 ULP, it is considered to be within the range of rounding errors associated with single-precision complex integration. if (abs(ss-result) < 5.0) then print *, "PASS" else print *, ss, abs(ss-result) endif Expected values: (-15069242.0, -9596797.00) Actual values: (-15069245.0, -9596802.00) Therefore, we make the following two corrections. ・To verify OpenMP SIMD reduction, which is the original objective, specify the -fopenmp option. ・Due to vectorization, a difference of 3 ULP in the real part and 5 ULP in the imaginary part has arisen in the single-precision complex multiplication. In this test, the size of the complex difference is calculated as abs(ss - result)\ , but the current threshold of 5.0 does not allow for a complex difference of 5.8309517. To allow for rounding errors of approximately 5 ULP as complex differences, the threshold will be relaxed from 5.0 to 6.0. 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 4 月 30 日 (木曜日) 0:41 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> 件名: [Linaro-TCWG-CI] llvmorg-23-init-12953-g1348766d1d68: 1 regression on aarch64 [Some people who received this message don't often get email from ci_notify(a)linaro.org.
