Hi, The failures were caused by re-applying the LLVM change introduced by commit(efd053f8ef306e6fa21ab0cd1bd185ef48f09fc0). Although the change had previously been reverted due to regression failures, it was later re-applied unchanged by commit(44ea65c07a600ca1c32912b5cd7356f6792b2b03). This reintroduced the same failures that had already been reported in LLVM-2266.

The issue has already been addressed as part of the resolution for LLVM-2266, and the corresponding fix was committed in: https://dev.azure.com/miratech-soft/b6c3f009-db3a-422a-91be-d5c0809bb862/_gi...

Please ignore the mail. We apologize for the false detection.

Best regards, Yasuyuki Ohno
