Re: [CI-NOTIFY]: TCWG Bisect tcwg_kernel/llvm-master-aarch64-lts-allmodconfig - Build # 6 - Successful!

by Maxim Kuvyrkov

Hi Greg, This appears to have been a fluke. Boot-testing succeeded before the merge and failed after. Boot-testing on allmodconfig doesn’t seem to be stable, so we are going to disable it.

[TCWG CI] 464.h264ref slowed down by 6% after llvm: Revert "Allow rematerialization of virtual reg uses"

by ci_notify＠linaro.org

After llvm commit 08d7eec06e8cf5c15a96ce11f311f1480291a441 Author: Stanislav Mekhanoshin <Stanislav.Mekhanoshin(a)amd.com> Revert "Allow rematerialization of virtual reg uses" the following benchmarks slowed down by more than 2%: - 464.h264ref slowed down by 6% from 11014 to 11697 perf samples - 464.h264ref:[.] FastFullPelBlockMotionSearch slowed down by 40% from 1513 to 2118 perf samples 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_llvm-bisect-tcwg_bmk_tx1-llvm-master-… - Last_good save-temps: https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_tx1-llvm-master-… - Baseline save-temps: https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_tx1-llvm-master-… Configuration: - Benchmark: SPEC CPU2006 - 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(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.

[TCWG CI] 401.bzip2 grew in size by 2% after llvm: Revert "Allow rematerialization of virtual reg uses"

by ci_notify＠linaro.org

After llvm commit 08d7eec06e8cf5c15a96ce11f311f1480291a441 Author: Stanislav Mekhanoshin <Stanislav.Mekhanoshin(a)amd.com> Revert "Allow rematerialization of virtual reg uses" the following benchmarks grew in size by more than 1%: - 401.bzip2 grew in size by 2% from 46428 to 47368 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_llvm-bisect-tcwg_bmk_apm-llvm-master-… - Last_good save-temps: https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_apm-llvm-master-… - Baseline save-temps: https://ci.linaro.org/job/tcwg_bmk_ci_llvm-bisect-tcwg_bmk_apm-llvm-master-… Configuration: - Benchmark: SPEC CPU2006 - Toolchain: Clang + Glibc + LLVM 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.

[TCWG CI] 462.libquantum grew in size by 3% after llvm: [JumpThreading] Ignore free instructions

by ci_notify＠linaro.org

After llvm commit 1e3c6fc7cb9d2ee6a5328881f95d6643afeadbff Author: Nikita Popov <nikita.ppv(a)gmail.com> [JumpThreading] Ignore free instructions the following benchmarks grew in size by more than 1%: - 462.libquantum grew in size by 3% from 14035 to 14398 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.

Free instructions should be ignored for the threading decision. JumpThreading already skips some free instructions (like pointer bitcasts), but does not skip various free intrinsics -- in fact, it currently gives them a fairly large cost of 2.

On a local machine one can just do /proc/cpuinfo, but in case of running tests using a remote system that distributes test runs to other remote systems that are not directly accessible, that's not possible. Fix this by dumping /proc/cpuinfo into the gdb.log, as well as lsb_release -a and uname -a. We could do this at the start of each test run, by putting it into unix.exp or some such. However, this might be too verbose, so we choose to put it into its own test-case, such that it get triggered in a full testrun, but not when running one or a subset of tests. We put the test-case into the gdb.testsuite directory, which is currently the only place in the testsuite where we do not test gdb. [ Though perhaps this could be put into a new gdb.info directory, since the test-case doesn't actually test the testsuite. ] Tested on x86_64-linux. --- gdb/testsuite/gdb.testsuite/dump-system-info.exp | 48 ++++++++++++++++++++++++ 1 file changed, 48 insertions(+) diff --git a/gdb/testsuite/gdb.testsuite/dump-system-info.exp b/gdb/testsuite/gdb.testsuite/dump-system-info.exp new file mode 100644 index 00000000000..bf181469bd5 --- /dev/null +++ b/gdb/testsuite/gdb.testsuite/dump-system-info.exp @@ -0,0 +1,48 @@ +# Copyright 2021 Free Software Foundation, Inc. +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[TCWG CI] 464.h264ref slowed down by 3% after llvm: Fix test from 8dd42f, capitalization in test

by ci_notify＠linaro.org

After llvm commit e8e2edd8ca88f8b0a7dba141349b2aa83284f3af Author: Erich Keane <erich.keane(a)intel.com> Fix test from 8dd42f, capitalization in test the following benchmarks slowed down by more than 2%: - 464.h264ref slowed down by 3% from 10973 to 11249 perf samples - 464.h264ref:[.] FastFullPelBlockMotionSearch slowed down by 12% from 1446 to 1619 perf samples 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.

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.

Re: [TCWG CI] 456.hmmer slowed down by 6% after llvm: Allow rematerialization of virtual reg uses

Thanks, Stanislav, FWIW, it will be, probably, easier for you to just rebuild the compiler, it is an x86_64-linux-gnu -> arm-linux-gnueabihf cross. This link has the build log [1]. cmake -G Ninja ../llvm/llvm '-DLLVM_ENABLE_PROJECTS=clang;lld' -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=True -DCMAKE_INSTALL_PREFIX=../llvm-install -DLLVM_TARGETS_TO_BUILD=ARM Then compile the pre-processed source with plain -O2 or -O3 optimisation settings.
