Dear contributor, our automatic CI has detected problems related to your patch(es). Please find some details below. If you have any questions, please follow up on linaro-toolchain@lists.linaro.org mailing list, Libera's #linaro-tcwg channel, or ping your favourite Linaro toolchain developer on the usual project channel.
In CI config tcwg_bmk-code_size-cpu2017fast/gnu-aarch64-master-O3_LTO after:
| 320 commits in gcc
| c4a8f441421 vect: Adjust vectorizable_load costing on VMAT_LOAD_STORE_LANES
| 131943ca22e vect: Adjust vectorizable_load costing on VMAT_GATHER_SCATTER
| 090d83c2550 vect: Adjust vectorizable_load costing on VMAT_ELEMENTWISE and VMAT_STRIDED_SLP
| bbee29e8288 vect: Adjust vectorizable_load costing on VMAT_INVARIANT
| 2115c22617c vect: Adjust vectorizable_load costing on VMAT_GATHER_SCATTER && gs_info.decl
| ... and 315 more commits in gcc
No change
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: GCC + Glibc + GNU Linker
- Version: all components were built from their tip of trunk
- Target: aarch64-linux-gnu
- Compiler flags: O3 -flto
- 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.
