Re: [Linaro-TCWG-CI] gcc-16-6952-g14cd2833b27a: 7 regressions on master-thumb_v8a_hard_eabi

by Alexandre Oliva

The test fails on arm-eabi when testing with the following settings: -mlittle-endian -mfloat-abi=hard -mcpu=cortex-a9 -mfpu=vfpv3 It only fails in the following torture option set: -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions It also fails on numerous other 32-bit targets, but it depends on how the memcpy-like loop gets vectorized and unrolled. I hope we can live with the XPASSes. On Apr 11, 2026, ci_notify(a)linaro.org wrote: > Dear contributor, > Our automatic CI has detected problems related to your > patch(es).

Potentially dodgy caching on flang-arm64-windows-msvc

by Luke Lau

Hi there, I got a notification about a build failure on the flang-arm64-windows-msvc buildbot earlier today, I’ve included the original email below. The commit in question that caused the failure added some new intrinsics, touching some tablegen files, which then caused some tests for unrelated intrinsics to fail: https://github.com/llvm/llvm-project/commit/9ba774566e27b76b9c7c2b2ddd108c1… https://lab.llvm.org/buildbot/#/builders/207/builds/15865 But the buildbot went back to green in https://lab.llvm.org/buildbot/#/builders/207/builds/15869 when another PR changed some other tablegen files in the llvm project. I didn’t revert or commit any fixes in the meantime. Is there maybe some issue with the build cache and how tablegen files interact with it? Just thought I’d flag this to you anyway.

Re: [Linaro-TCWG-CI] gcc-16-7434-g6b550d69fe7c: 2 regressions on master-thumb_m55_hard_eabi

I think this is the same issue as reported in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=124124, that was addressed by: commit r16-7911-g3a41229f92022bfb388911854d597721fce76714 <https://gcc.gnu.org/cgit/gcc/commit/?id=3a41229f92022bfb388911854d597721fce…> Author: Tomasz KamiÅski <tkaminsk(a)redhat.com> Date: Thu Mar 5 08:57:24 2026 +0100 libstdc++: Fix atomic/cons/zero_padding.cc test for arm-none-eabi [PR124124 <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=124124>] The test uses dg-require-atomic-cmpxchg-word that checks if atomic compare exchange is available for pointer sized integers, and then test types that are eight bytes in size. This causes issue for targets for which pointers are four byte and libatomic is not present, like arm-none-eabi. This patch addresses by using short member in TailPadding and MidPadding, instead of int. This reduces the size of types to four bytes, while keeping padding bytes present.

[Fortran, PR124484, v1] Fix testing caf_shmem on aarch64-*-linux was: [Linaro-TCWG-CI] gcc-16-7727-gaa09298cb017: 157 regressions on aarch64

by Andre Vehreschild

Hi all, the linaro CI reported test errors for aarch64 targets. I figured that for aarch64 on linux the compile flags -pthread and -lrt are needed to link caf_shmem and produce an executable. The attached patch addresses this by special case for aarch64-*-linux* similiar to freebsd. Regtested ok on aarch64-unknown-linux-gnu (cfarm185) and x86_64-linux-gnu / F43. Ok for master?

Re: [Linaro-TCWG-CI] gcc-16-5627-g4e7213aa081f: 1 regression on master-thumb_m55_hard_eabi

by Tomasz Kaminski

Hi, I am unable to reproduce the issue, and cannot access the included log files to check the failure. Could you please share the revelant part of log, at least from time/hash.cc?
