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

Re: [Linaro-TCWG-CI] FAIL: 1 regressions after gcc commit

by Adhemerval Zanella Netto

Hi Andrew, Your patch caused a regression [1] on aarch64-linux-gnu. Would you please investigate? I did a quick analysis and it seems that the expected 18 for aarch64 is now 17: $ grep "Jumps threaded" a-ssa-dom-thread-7.c.197t.thread2 Jumps threaded: 17 Let me know if you need any assistance in reproducing these. Thanks! [1] https://ci.linaro.org/job/tcwg_gnu_native_check_gcc--master-aarch64-build/5…

[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
