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: 
 - Toolchain: Clang + Glibc + LLVM Linker
 - Version: all components were built from their tip of trunk
 - Target: arm-linux-gnueabihf
 - Compiler flags: Oz -LTO
 - Hardware: <unknown>
 
 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.

If you have any questions regarding this report, please ask on linaro-toolchain@lists.linaro.org mailing list.
