Hi, Probably this error is false detections caused by precision errors in floating-point arithmetic. Please ignore the mail. We'll update the test. I apologize for the false detection.
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5月24日 17:20 宛先: [email protected] <[email protected]> CC: [email protected] <[email protected]>; [email protected] <[email protected]> 件名: [Linaro-TCWG-CI] llvmorg-23-init-15954-g998d8e87daf3: 2 regressions on aarch64 Dear contributor, Our automatic CI has detected problems related to your patch(es).
