Re: [Linaro-TCWG-CI] FAIL: 6 regressions after gcc commit: basepoints/gcc-14-3331-gcddc26e0274 aarch64: Fine-grained ldp and stp policies with test-cases.

[ACTIVITY] Report for week #33

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Continued working on new approach to support changing SVE vector length in remote debugging. # TCWG CI - Analysed GCC regression GNU-880 which is actually an XFAIL → XPASS so I sent a patch removing the xfail annotation. - Analysed GCC regression GNU-881. The problem is that we don't have Python in the ABE sysroot so a new Python GCC plugin testcase fails to build. Sent a patch to detect that situation and mark the test as unsupported. It was committed upstream. - Tested a couple of new versions of a GDB mailing list patch to see if it fixed the failure reported by the precommit CI. Reported results to patch author. - Fixed silly mistake spotted by Laurent in ABE Gerrit requests to use TIMEOUTFACTOR for DejaGnu testsuites. Adjusted it to not use the factor in GDB on armhf and sent new version for review. - Reviewed a couple of Gerrit requests. -- Thiago

[ACTIVITY] report week ending 18 Aug

by Peter Maydell

Progress (short week, 3 days): * UM-2 [QEMU upstream maintainership] - sent out another couple of "avoid VLA" patches * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - managed to write some first-pass code for the MTE checks for FEAT_MOPS memset operations. Got something together enough to send to RTH for some pre-review before I roll the approach out to the other insns. -- PMM

LLVM bots down for extended period

by Aaron Ballman

Hello! You are the point of contact for some build bots in the LLVM build lab that have been down for an extended period of time. If you're not the correct point of contact, can you please CC the right individual (if you know who they are)? The following bot(s) appear to have been down for multiple weeks: https://lab.llvm.org/buildbot/#/builders/clang-armv7-global-isel https://lab.llvm.org/buildbot/#/builders/clang-native-arm-lnt-perf https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vla-2stage https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vls-2stage https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vls https://lab.llvm.org/buildbot/#/builders/clang-armv7-vfpv3-full-2stage https://lab.llvm.org/buildbot/#/builders/clang-thumbv7-full-2stage Do you have plans to bring the bot back online? If not, that's okay -- just let me know and I can remove the bots from the lab for you. Thank you! ~Aaron

CMake requirements LLVM buildbots

by Mark de Wever

Hi, As discussed in [1] I just committed [2] to update the minimum CMake version in LLVM to 3.20.0. Unfortunately it seems the ARM builders in the libc++ precommit CI are running CMake 3.16.3 [3]. Would it be possible to update these builders? [1] https://discourse.llvm.org/t/rfc-upgrading-llvms-minimum-required-cmake-ver… [2] https://reviews.llvm.org/D144509a [3] https://buildkite.com/llvm-project/libcxx-ci/builds/19366#0186756a-1599-46e… Thanks, Mark

[ACTIVITY] Report for week #32

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Returned to implementing support for changing SVE vector length in remote debugging. The patch series I sent earlier this year used an approach that some maintainers weren't enthusiastic about (modifying the Remote Serial Protocol to request XML target descriptions). Now trying the approach they suggested, which is to extend target descriptions to support expressing vector registers whose length is given by the contents of another register. # TCWG CI - Following Maxim's suggestion, sent and merged Gerrit review requests to increase chance of tcwg_gdb_check jobs to be faster at detecting new or newly expired flaky tests: - 45151: tcwg_gdb: Increase job frequency - 45152: round-robin.sh (build_abe): Increase time to re-detect GDB flaky tests - Implemented change in ABE to support glibc's TIMEOUTFACTOR environment variable for DejaGnu testsuites. Testing on armv8l and aarch64. -- Thiago

[ACTIVITY] report week ending 11 Aug

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - code review, notably: + RTH's setnegcond series + Jean-Philippe's fixes for various FEAT_RME bugs + Akihiko's series to make KVM '-machine none' not default to 40 bits of IPA space if the host doesn't supoprt that (like the Apple CPUs) - sent a patch to catch the illegal exception return case from EL3 with bad SCR_EL3.{NSE,NS} - respin and resend of ptw cleanup patchset - tidied another 'BiteSizedTask' entry into a gitlab issue - went back to an old minor cleanup task: getting rid of the last dozen or so uses of variable-length arrays in the codebase (so we can enforce not using them in the compiler, and avoid unchecked-on-stack-allocation security bugs). Sent patches to zap a few more. * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - thinking a bit more about FEAT_MOPS and MTE checks, but ultimately not much progress: didn't find enough hours with a sufficiently alert mind... -- PMM

Hello, # TCWG CI - Implemented increasing testsuite timeout for each testsuite try in GDB check jobs. Sent a Gerrit review request for it but then found out that it makes armhf jobs take a lot longer, so abandoned it. # Community - Finished reviewing SME patches for GDB and gdbserver. -- Thiago
