[TCWG CI] [TCWG CI] 465.tonto failed to build after gdb-13-branchpoint-527-g46758593515: Rename to allow_ifunc_tests

by ci_notify＠linaro.org

After gdb-13-branchpoint-527-g46758593515 commit 4675859351582f017b495ff13fb2ea72a99834af Author: Tom Tromey <tom(a)tromey.com> Rename to allow_ifunc_tests the following benchmarks slowed down by more than 3%: - 465.tonto failed to build 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 CPU2006 - Toolchain: GCC + Glibc + GNU Linker - Version: all components were built from their tip of trunk - Target: aarch64-linux-gnu - Compiler flags: -O3 - Hardware: This benchmarking CI is work-in-progress, and we welcome feedback and suggestions at linaro-toolchain(a)lists.linaro.org .

[ACTIVITY] Report for week #3

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Continued preparing patches for upstream submission. Realised I had to document my changes to the remote protocol in the GDB manual, so did that. Also making small code cleanups and updating/rewriting patch descriptions. - Noticed I could to a small optimisation in one patch, but it would involve a lot of refactoring to move GDB-specific code so that it could also be used by gdbserver, so saved the WIP branch for later. # TCWG CI - Investigated failure report from yesterday's email. Reproduced on tcwg-jade-03 with a slightly different build failure, but wasn't able to make much progress¹. -- Thiago ¹ https://lists.linaro.org/archives/list/linaro-toolchain@lists.linaro.org/th…
