Re: [Linaro-TCWG-CI] gcc-14-8887-gd9459129ea8: FAIL: 29 regressions on master-thumb_m33_eabi

by Richard Earnshaw

I think all of these actually fall under "I suspect there are still some further issues to address here, since the framework does not correctly test that the multilibs and startup code enable alternative format; but this is still an improvement over what we had before." All the failures are execution test failures due to the fact that we don't check the available hardware/multilibs for running the test; so blindly adding options and then running the test is incorrect. But we currently lack such a test in the framework. It's also less than clear exactly what these tests are checking and which part of what they are checking that really requires the options they add. I suspect that they previously passed only by accident (they didn't really add enough flags to enable what they author thought they were checking). R.

RE: [Linaro-TCWG-CI] gcc-14-8499-gbad991a1c59: FAIL: 1 regressions on master-thumb_m0_eabi

by Matthieu Longo

Hi, The regression was introduced after we added a new test (rev16_2.c) in https://github.com/gcc-mirror/gcc/commit/bad991a1c5960e90c4686a9362a1258ef2…. The generated code is functionally correct, but the optimization is disabled when -mthumb is equivalent to Thumb1. The fix would not be suitable for stage 4. Instead, I opened a Jira ticket on our side to track the issue and prioritize it. In the meantime, I am going to publish a patch to mark the test as XFAIL when used with thumb1.

[ACTIVITY] report week ending Feb 2

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - more code review and pullreq wrangling * QEMU-598 [Model the MPS3-AN536 dual-Cortex-R52 FPGA image] - Wrote code to create the CPUs and the GIC and the UARTs. (Decided in the end not to try to create an a15mpcore-style wrapper device for the CPUs and GIC, because the need to have per-CPU RAM and UARTs makes that a bit awkward.) - Got to a working implementation which can boot the selftest binary and run those parts of the selftest which we expect to work. Also will boot a Linux kernel (support for R52 is not upstream but there are public mailing list patches). - Started on tidying up the patchset and finishing off the loose ends to get it into a state where it can be sent out: hope to be able to do that first half of next week. -- PMM

Re: [Linaro-TCWG-CI] gdb-14-branchpoint-1426-gb960445a459: FAIL: 1 regressions on arm

by Maxim Kuvyrkov

Hi All, This is a false positive, obviously. We do our best to filter out flaky tests, but in this case "gdb.threads/staticthreads.exp: up 10" PASSed twice in the previous run, and then FAILed twice in the next run. Sneaky! Re. the FAIL, the testcase expects to be " in main .*" after "up 10", but ends up in pthread_join() instead: === up 10 #4 0x0001b864 in pthread_join () (gdb) FAIL: gdb.threads/staticthreads.exp: up 10 === See [1] for details. [1] https://ci.linaro.org/job/tcwg_gdb_check--master-arm-build/752/artifact/art… . Hi Thiago, Would you please investigate whether ending up in pthread_join() is expected/reasonable for 32-bit ARM? In other words, whether we have a GDB bug exposed by staticthreads.exp or the testcase needs to be generalized a bit.
