Hi, This test is incorrect. I apologize for the false detection. This issue involves the emergence of precision errors due to a change in the evaluation path for complex number division. Therefore, we will correct the tests. It may take some time due to our internal release process, sorry.
Best regards, Yasuyuki Ohno Software Development Div., Advanced Technology Development Unit, Fujitsu Research, Fujitsu Limited, JAPAN. ________________________________ 差出人: [email protected] <[email protected]> 送信日時: 2026年6月15日 14:56 宛先: [email protected] <[email protected]> CC: [email protected] <[email protected]>; [email protected] <[email protected]> 件名: [Linaro-TCWG-CI] llvmorg-23-init-18988-g9ce63d09cff0: 2 regressions on aarch64 Dear contributor, Our automatic CI has detected problems related to your patch(es).
