The kernel side fix for this has been picked up in a maintainer's tree [1] so it should be in Linus's tree soon then into stable shortly after that. This was already a problem in certain trees with CONFIG_KCSAN and __SANITIZE_THREAD__, I just made it a little worse ;) [1]: https://git.kernel.org/akpm/mm/c/3fac212fe489aa0dbe8d80a42a7809840ca7b0f9 Cheers, Nathan

Re: [Linaro-TCWG-CI] gcc-16-3649-gc440b585ba3: 4 regressions on master-thumb_m3_softfp_eabi

by Luc Grosheintz

I'd like to apologize for causing these regressions. Below I've copied out the relevant parts from the logs. To me it looks like _Xv is a reserved identifier. I'll prepare a patch to fix the issue.

RE: [Linaro-TCWG-CI] llvmorg-22-init-6821-ga103b9b207f6: 1 regression on aarch64

by Jean Perier

Thanks for the report. There is also an LLVM issue tracking this. I commented there: https://github.com/llvm/llvm-project/issues/157763#issuecomment-3273773003 The test is violating F2023 C15121 that is not properly enforced by flang semantics but that lowering now relies on. Although we will likely improve LEN lowering which would have the side effect of working around the segfault in the specific case of 0727_0008, I think we will enforce C15121 in a manner that will reject it. See The LLVM link for more details and suggestion on how to fix the test.

Hi, Probably this failure is a false detection caused by the fast-math flag. The test uses NaN and very large values. Appending -fhonor-nans -fhonor-infinities resolves the failure.

[PATCH] [arm] require armv7 support for [PR120424] (was: Re: [PATCH, FYI?] [arm] [vxworks] require thumb2 for pr120424.C)

It turned out that the regression report I got from linaro was related https://linaro.atlassian.net/browse/GNU-1599 While testing a configuration with -mfloat-abi=hard, -marmv7 is rejected because it doesn't have an FPU. Requiring thumb2 wouldn't have avoided this failure, but requiring armv7 is a proper fix for both problems. (sorry it me took so long; I'm still busy busy with other fp2sp-elimination-disabled-during-lra problems affecting arm) Without stating the architecture version required by the test, test runs with options that are incompatible with the required architecture version fail, e.g. -mfloat-abi=hard. armv7 was not covered by the long list of arm variants in target-supports.exp, so add it, and use it for the effective target requirement and for the option. Tested on arm-eabi, and also on arm-vx7r2 with gcc-14.

How can I reproduce a flang-arm64-windows-msvc LLVM buildbot error?

by tobias.gysi＠nextsilicon.com

Dear Linaro Community, I am looking for advice on how to reproduce a flang-arm64-windows-msvc LLVM build bot failure (hopefully I ended up in the right place here). I had to revert an LLVM PR (https://github.com/llvm/llvm-project/pull/150783) that broke the flang-arm64-windows-msvc LLVM buildbot yesterday due to some tablegen-related problem. I did prepare a reland PR (https://github.com/llvm/llvm-project/pull/151125) that addresses a potential issue. However, since I did not see any other buildbot failures and since I was not able to reproduce the problem locally, I wonder if there is a way to run the flang-arm64-windows-msvc buildbot on my reland PR? Alternatively, hints on how to reproduce the problem locally on a x86 Linux machine would be appreciated. Best, Tobias

It appears that this build was running tests on qemu that doesn't seem to support the same signal handling behaviour for SME as would the kernel that supports SME. On a system that supports SME with kernel 6.16 these tests work as expected provided that their dependencies are resolved by dynamic loader to the new version of libgcc. So, no issue in the patch or in the tests. Thanks, Yury IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.

Re: [Linaro-TCWG-CI] gcc-16-2334-g9e330977385: 2 regressions on arm

by Jonathan Wakely

Tomasz, The new __any_input_iterator type should only be declared for C++20 and higher, so guarded by __cpp_lib_concepts Just checking __cpp_concepts isn't enough, because that's true for -std=c++17 -fconcepts but std::input_iterator isn't defined in that case.
