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: arm-linux-gnueabihf - Compiler flags: O3 - Hardware: 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. -----------------8<--------------------------8<--------------------------8<-------------------------- The information below can be used to reproduce a debug environment: Current build : https://ci.linaro.org/job/tcwg_bmk-code_vect-cpu2017rate--llvm-arm-master-O3-build/83/artifact/artifacts Reference build : https://ci.linaro.org/job/tcwg_bmk-code_vect-cpu2017rate--llvm-arm-master-O3-build/80/artifact/artifacts
