Re: [Linaro-TCWG-CI] gcc patch #142437: 2 regressions on aarch64

by Lunex

Hi, thanks for the report. I looked into this and I dont think my patch is actually responsible for these failures. The gcov-39.c prime-paths test seems to be a pre-existing flaky test rather than something introduced by my changes — my patch only touches the tree optimization path (final value replacement logic) and has no interaction with gcov instrumentation or path coverage counting. Could someone check if this failure shows up in the baseline as well? Happy to dig deeper if needed, but from what I can see this looks unrelated to my patch. Thanks --------- Lunex<imlunex2011(a)gmail.com>

I have a hunch gcc.misc-tests/gcov-39.c is flaky, if not generally then at least in the context of your CI.

Re: [Linaro-TCWG-CI] 4 patches in gcc: 2 regressions on aarch64

Hi, I believe these may be flaky since I checked with my 4 patches on cfarm185 machine with following configure command configure --prefix=/home/avinashd/opt --enable-languages=c,c++ -- target=aarch64-unknown-linux-gnu --disable-multilib --enable-fix- cortex-a53-835769 --enable-fix-cortex-a53-843419 --with-arch=armv8-a -- disable-bootstrap on top of the commit a5da203dd95900ba8bab16432667989f3d018c76 : xtensa: Make use of CONST.S instruction On Fri, 2026-08-28 at 22:17 +0000, ci_notify(a)linaro.org wrote: > Dear contributor, > > Our automatic CI has detected problems related to your patch(es). > Please find some details below. > > In aarch64 native, after: > | 4 patches in gcc > | Patchwork URL: https://patchwork.sourceware.org/patch/142333 > | 25ff335aad8 [PATCH 4/4] rs6000: Add sha3 builtins and > documentation [RFC02645] > | f47d33c1b4e [PATCH 3/4] rs6000: Add __dmr2048 type (QDOmode) and > map it to DMR pair register > | 1eb45af654c [PATCH 2/4] genmodes: Use wider types for > mode_unit_size array based on max size The only change in middle-end that has happened is with this patch (2/4).

Re: [Linaro-TCWG-CI] 5 patches in gcc: 2 regressions on aarch64

by Richard Earnshaw

No, this isn't plausible. The maintainer_utils changes have no effect at all on the compiler. So there must be some other cause. R.

Re: [Linaro-TCWG-CI] llvmorg-24-init-4794-gefd053f8ef30: 3 regressions on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, Two independent failures were observed in the test-suite. Both failures are caused by pre-existing undefined behavior in the test programs: 1. Accessing elements through a std::initializer_list after the lifetime of its backing temporary array has ended. 2. Reading uninitialized automatic variables. The commit (efd053f) merely exposed these latent issues through improved lifetime-aware optimization. Therefore, this is the test-suite issue, not a compiler defect. Please ignore the mail. We will update the test. We apologize for the false detection. Best regards, Yasuyuki Ohno Software Development Div., Advanced Technology Development Unit, Fujitsu Research, Fujitsu Limited, JAPAN. ________________________________ 差出人: ci_notify(a)linaro.org <ci_notify(a)linaro.org> 送信日時: 2026年8月21日 21:40 宛先: contact-ci-compiler-test-suite(a)cs.jp.fujitsu.com <contact-ci-compiler-test-suite(a)cs.jp.fujitsu.com> CC: isoard(a)amd.com <isoard(a)amd.com>; maxim.kuvyrkov(a)linaro.org <maxim.kuvyrkov(a)linaro.org> 件名: [Linaro-TCWG-CI] llvmorg-24-init-4794-gefd053f8ef30: 3 regressions on aarch64 Dear contributor, Our automatic CI has detected problems related to your patch(es).

Thanks for the report. I compared builds 10158 and 10159. The additional breakpoint is for _dl_relocate_static_pie_ifunc in static-reloc.c:28. Before b6477e6c4ef, the function and its symbol were already present, but its IPA-ICF wrapper had no address-bearing subprogram DIE. With the change, GDB can now see the function when minsyms=False and set a breakpoint on it. This is the behavior PR debug/126355 was intended to restore, so the result also provides useful confirmation that the GCC fix is effective. The failure comes from py-rbreak.exp using the unanchored regexp "func.*". It now also matches the "ifunc" suffix of _dl_relocate_static_pie_ifunc, changing the result from nine breakpoints to ten. GDB, glibc, binutils and Linux are unchanged between the two builds; the GCC revisions are this commit and its immediate parent. Changing the expected count to ten would make the test depend on the target startup objects. A more robust fix would be to narrow the two unscoped regexp uses in the exact-count and throttle checks, for example to "^e?func.*", so that they only select functions defined by the test. I therefore do not think this is a GCC regression. It looks like the GDB test needs to be made more specific. <ci_notify(a)linaro.org> 于2026年8月24日周一 11:47写道： > Dear contributor, > > Our automatic CI has detected problems related to your patch(es).
