Re: [EXT] [Linaro-TCWG-CI] 2 patches in gcc: FAIL: 1 regressions

by Andrew Pinski

Just FYI. This test is just bogus and fixing it might be simple as using -fsanitize=undefined to check at runtime there is no undefined behavior being hit. In this case even if we do the comparison in `signed` and do the negate in `unsigned` types. we can still remove the negate in this case since we know the only value that will be still negative in that branch is LONG_MIN. So my patch just simplifies the inner comparison to that instead of `a < 0` and then be able to remove the neg. Someone else will have to fix the testcase since it is a testcase issue ... ________________________________________ From: ci_notify(a)linaro.org <ci_notify(a)linaro.org> Sent: Friday, September 1, 2023 3:07 PM To: Andrew Pinski Subject: [EXT] [Linaro-TCWG-CI] 2 patches in gcc: FAIL: 1 regressions External Email ---------------------------------------------------------------------- Dear contributor, our automatic CI has detected problems related to your patch(es).

[Linaro-TCWG-CI] FAIL: regressions after gcc commit 0c78240fd7d519fc27ca822f66a92f85edf43f70

by Adhemerval Zanella Netto

Hi Jan, Your patch caused a regression [1] on aarch64-linux-gnu. Would you please investigate? I am having some trouble to reproduce it outside our CI environment, but it has been hitting this issues consistently and it does seems related to your patch. Let me know if you need any assistance in reproducing these. Thanks! [1] https://ci.linaro.org/job/tcwg_bootstrap_build--master-aarch64-bootstrap_pr…

by Adhemerval Zanella Netto

Hi Richard, Your patch caused a regression [1] on aarch64-linux-gnu. Would you please investigate? I did a quick analysis and it seems that for test_copy_lane_f32, test_copy_lane_s32, test_copy_lane_u32, gcc is now generating zip1 instead of a ins; which does not seem fully correct. Let me know if you need any assistance in reproducing these. Thanks! [1] https://ci.linaro.org/job/tcwg_gnu_cross_check_gcc--master-aarch64-build/91…

[ACTIVITY] Report for week #34

by Thiago Jung Bauermann

Hello, # TCWG CI - GCC regression GNU-884: Prathamesh confirmed that the new generated code is better so I posted a patch adjusting the testcase. - GCC regression GNU-885: Confirmed that the problem is still present in trunk as of commit 829c0c06fe7b from yesterday, so opened bugzilla 111125 and copied the patch author. He fixed the regression. - Posted Gerrit review request to increase timeout for GDB check jobs to accommodate longer times for Armv8l builds. # GDB Upstream - Reviewed v4 of Luis' patch series adding SME support to GDB and gdbserver. -- Thiago

[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

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

Progress: * UM-2 [QEMU upstream maintainership] - some bits and pieces for release - code review, notably: + raspberry pi 4 support patchseries (a big 44-patch set) + Xilinx Versal CFI support patches * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - more work on FEAT_MOPS: tested my memset implementation, and fixed various bugs. Still no MTE tag checking support. -- PMM

[ACTIVITY] report week ending 28 Jul

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - release related stuff: handling merge requests, etc (now passed back to RTH again) - sent some patches for a few easy coverity issues - worked through some code review (in particular some patches from new contributors) - created a gitlab "bite sized task" issue that better explains and has more detail on the "convert from malloc to g_malloc" suggested task for new contributors * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - a little more progress with FEAT_MOPS. I now have an untested implementation of the memset insns which I think is complete except for MTE tag checking -- PMM
