Hello, # TCWG CI - Flakiness in gdb.base/gdb-sigterm.exp causes false positives on tcwg_check_gdb--master-arm-precommit, so started investigating its failures. - Investigated regressions reported by the CI: - GCC regression GNU-935: Not a real regression, just already existing failures being reported for a new version of the C++ standard. - linux-next regression GNU-936: Fixed in the newest linux-next tree. - GCC regression GNU-962: Opened GCC bug 111802 ("New analyser diagram failures since commit b365e9d57ad4"). - GCC regression GNU-965: Arm already opened GCC bug 111784 ("[14 Regression] aarch64: ldp_stp_{15,16,17,18}.c test failures since r14-4579.") about this issue. - GCC regression GNU-966: This problem has been fixed in trunk. - linux-next regression GNU-967: A patch was sent to fix the error. # [GNU-767] Support changing SVE vector length in remote debugging - Working on adapting gdbserver's regcache to support registers with a variable size. - Also enabling the target description XML to express vector register sizes in terms of another register. -- Thiago

Fwd: [Linaro-TCWG-CI] llvmorg-18-init-7933-ge13bed4c5f35: slowed down by 6% - 464.h264ref on aarch64 O2

by Maxim Kuvyrkov

Hi Dmitriy, Linaro Benchmarking CI has flagged several interesting code-speed and code-size regressions for your patch -- see [1]. In particular, could you check if below regressions can be avoided: - grew in size by 21% - 473.astar:[.] _ZN7way2obj12releasepointEii - slowed down by 61% - 505.mcf_r:[.] price_out_impl Both of these are for 32-bit ARM, but AArch64 also has code-speed and code-size regressions. Let me know if you need any assistance in reproducing these problems. [1] https://linaro.atlassian.net/browse/LLVM-1001 Kind regards, -- Maxim Kuvyrkov https://www.linaro.org > Begin forwarded message: > > From: ci_notify(a)linaro.org > Subject: [Linaro-TCWG-CI] llvmorg-18-init-7933-ge13bed4c5f35: slowed down by 6% - 464.h264ref on aarch64 O2 > Date: October 8, 2023 at 04:26:39 GMT+4 > To: maxim.kuvyrkov(a)linaro.org > Reply-To: linaro-toolchain(a)lists.linaro.org > > Dear contributor, our automatic CI has detected problems related to your patch(es).

[ACTIVITY] Report for weeks #37 to #40

by Thiago Jung Bauermann

Hello, Attended two events in a row in September, so had a bit of a time crunch and the weekly report fell through the cracks... # TCWG CI - Investigated and fixed a few false positives in the GDB precommit CI which were caused by random failures in gdb.threads/process-dies-while-detaching.exp. Posted upstream and later committed patch fixing the testcase to be more stable. - After conversations during GNU Tools Cauldron and following Maxim's suggestion, changed Linaro's CI to use the read1 library while running the GDB testsuite to improve the stability of its results. - After review from Tom Tromey, posted v2 and later committed a patch which adds '--with-additional-debug-dirs' configure option. - Committed a couple of changes to our CI scripts which make sure that the kernel.yama.ptrace_scope and kernel.core_pattern sysctls have correct values for running the GDB testsuite. # [GNU-767] Support changing SVE vector length in remote debugging - Now that Luis pushed his SME and SME2 patches, merged current GDB main branch into my local branch. It builds but doesn't work yet. # GDB Upstream - Reviewed patch series "[PATCH v3 0/4] Dynamic properties of pointers". - Investigated upstream bugzilla "18898 - Cannot specify non-default list of directories as argument of --with-auto-load-dir on Windows", but concluded it's an autoconf limitation that isn't easy to fix. # Misc - Prepared for Linaro's Employees Meeting. - Attended GNU Tools Cauldron. - Took a few days of vacation. -- Thiago
