Dear contributor, Our automatic CI has detected problems related to your patch(es). Please find some details below. In tcwg_bmk-code_speed-cpu2017rate/llvm-aarch64-master-O3, after: | commit llvmorg-20-init-12473-ga8538b913857 | Author: Julian Nagele | Date: Sun Nov 17 19:35:32 2024 +0000 | | [LV] Vectorize Epilogues for loops with small VF but high IC (#108190) | | - Consider MainLoopVF * IC when determining whether Epilogue | Vectorization is profitable | - Allow the same VF for the Epilogue as for the main loop | ... 7 lines of the commit log omitted. Produces No change: | No change Used configuration : Below reproducer instructions can be used to re-build both "first_bad" and "last_good" cross-toolchains used in this bisection. Naturally, the scripts will fail when triggerring benchmarking jobs if you don\'t have access to Linaro TCWG CI. Configuration: - Benchmark: SPEC CPU2017 - Toolchain: Clang + Glibc + LLVM Linker - Version: all components were built from their tip of trunk - Target: aarch64-linux-gnu - Compiler flags: O3 - Hardware: NVidia TX1 4x Cortex-A57 This benchmarking CI is work-in-progress, and we welcome feedback and suggestions at linaro-toolchain@lists.linaro.org . In our improvement plans is to add support for SPEC CPU2017 benchmarks and provide "perf report/annotate" data behind these reports. We track this bug report under https://linaro.atlassian.net/browse/LLVM-651. Please let us know if you have a fix. If you have any questions regarding this report, please ask on linaro-toolchain@lists.linaro.org mailing list. -----------------8<--------------------------8<--------------------------8<-------------------------- The information below contains the details of the failures, and the ways to reproduce a debug environment: Current build : https://ci.linaro.org/job/tcwg_bmk-code_speed-cpu2017rate--llvm-aarch64-master-O3-build/330/artifact/artifacts Reference build : https://ci.linaro.org/job/tcwg_bmk-code_speed-cpu2017rate--llvm-aarch64-master-O3-build/329/artifact/artifacts Instruction to reproduce the build : https://git-us.linaro.org/toolchain/ci/interesting-commits.git/plain/llvm/sha1/a8538b9138574142b9338ad0fce0f8ba1065fcbc/tcwg_bmk-code_speed-cpu2017rate/llvm-aarch64-master-O3/reproduction_instructions.txt Full commit : https://github.com/llvm/llvm-project/commit/a8538b9138574142b9338ad0fce0f8ba1065fcbc
