[TCWG CI] 458.sjeng grew in size by 4% after gcc: aarch64: Improve size heuristic for cpymem expansion

by ci_notify＠linaro.org

After gcc commit a459ee44c0a74b0df0485ed7a56683816c02aae9 Author: Kyrylo Tkachov <kyrylo.tkachov(a)arm.com> aarch64: Improve size heuristic for cpymem expansion the following benchmarks grew in size by more than 1%: - 458.sjeng grew in size by 4% from 105780 to 109944 bytes - 459.GemsFDTD grew in size by 2% from 247504 to 251468 bytes 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. For your convenience, we have uploaded tarballs with pre-processed source and assembly files at: - First_bad save-temps: https://ci.linaro.org/job/tcwg_bmk_ci_gnu-bisect-tcwg_bmk_apm-gnu-master-aa… - Last_good save-temps: https://ci.linaro.org/job/tcwg_bmk_ci_gnu-bisect-tcwg_bmk_apm-gnu-master-aa… - Baseline save-temps: https://ci.linaro.org/job/tcwg_bmk_ci_gnu-bisect-tcwg_bmk_apm-gnu-master-aa… Configuration: - Benchmark: SPEC CPU2006 - Toolchain: GCC + Glibc + GNU Linker - Version: all components were built from their tip of trunk - Target: aarch64-linux-gnu - Compiler flags: -Os -flto - Hardware: APM Mustang 8x X-Gene1 This benchmarking CI is work-in-progress, and we welcome feedback and suggestions at linaro-toolchain(a)lists.linaro.org . In our improvement plans is to add support for SPEC CPU2017 benchmarks and provide "perf report/annotate" data behind these reports. THIS IS THE END OF INTERESTING STUFF.

We count the number of ops emitted and compare it against the alternative of just calling the library function when optimising for size. For the code: void cpy_127 (char *out, char *in) { __builtin_memcpy (out, in, 127); } void cpy_128 (char *out, char *in) { __builtin_memcpy (out, in, 128); } we now emit a call to memcpy (with an extra MOV-immediate instruction for the size) instead of: cpy_127(char*, char*): ldp q0, q1, [x1] stp q0, q1, [x0] ldp q0, q1, [x1, 32] stp q0, q1, [x0, 32] ldp q0, q1, [x1, 64] stp q0, q1, [x0, 64] ldr q0, [x1, 96] str q0, [x0, 96] ldr q0, [x1, 111] str q0, [x0, 111] ret cpy_128(char*, char*): ldp q0, q1, [x1] stp q0, q1, [x0] ldp q0, q1, [x1, 32] stp q0, q1, [x0, 32] ldp q0, q1, [x1, 64] stp q0, q1, [x0, 64] ldp q0, q1, [x1, 96] stp q0, q1, [x0, 96] ret which is a clear code size win.

[ACTIVITY] report week ending 1 Oct

by Peter Maydell

Progress * UM-2 [QEMU upstream maintainership] + Worked through my code-review backlog + Noticed that we never got round to making our emulated GICv3 support having redistributors in more than one contiguous region; this prevents using more than 123 CPUs with the virt board. Sent out a patchset which adds the necessary handling. + Generally trying to tie off loose ends pre-holiday :-) -- PMM
