These are different warnings in different object files than from the initial report. Maybe bisection started due to those, but didn't notice different warnings going further back, because of -Werror, and reported the initial commit that was problematic (even if the warnings differed and were since fixed). > > These errors are near-misses, so if you are using a different LLVM revision, > they can disappear. > > [1] > https://ci.linaro.org/job/tcwg_kernel--llvm-master-arm-mainline-allmodconfig-build/110/artifact/artifacts/06-build_linux/console.log.xz > > [2] > https://ci.linaro.org/job/tcwg_kernel--llvm-master-arm-mainline-allmodconfig-build/111/artifact/artifacts/06-build_linux/console.log.xz > > -- > Maxim Kuvyrkov > https://www.linaro.org > > > On Nov 1, 2023, at 21:22, Nathan Chancellor wrote: > > > > On Wed, Nov 01, 2023 at 08:54:26AM -0700, Nick Desaulniers wrote: > >> On Wed, Nov 1, 2023 at 7:42 AM wrote: > >>> > >>> Dear contributor, our automatic CI has detected problems related to your > >>> patch(es).

Re: [Linaro-TCWG-CI] v6.6-rc1-17-g1c6fdbd8f246: Failure on arm
Hi Nick, Hi Nathan, I don't see mistakes from CI here. Are you using tip-of-trunk LLVM? This report was generated for LLVM revision llvmorg-18-init-10263-g1abd8d1a8d96 and linux revision v6.6-rc1-17-g1c6fdbd8f246 . The build log with errors is at [1]. It seems that a later commit in Linux kernel fixed some of the errors in [1], but still with the current linux.git:master 2 errors remain (see [2]): 00:28:15 fs/bcachefs/chardev.c:655:6: error: stack frame size (1032) exceeds limit (1024) in 'bch2_fs_ioctl' [-Werror,-Wframe-larger-than] 00:28:15 655 | long bch2_fs_ioctl(struct bch_fs *c, unsigned cmd, void __user *arg) 00:28:15 | ^ 00:28:15 1 error generated. 00:28:15 make[4]: *** [scripts/Makefile.build:243: fs/bcachefs/chardev.o] Error 1 00:29:39 fs/bcachefs/fs-common.c:356:5: error: stack frame size (1128) exceeds limit (1024) in 'bch2_rename_trans' [-Werror,-Wframe-larger-than] 00:29:39 356 | int bch2_rename_trans(struct btree_trans *trans, 00:29:39 | ^ 00:29:39 1 error generated. These errors are near-misses, so if you are using a different LLVM revision, they can disappear.

I cannot tell exactly from the information in this report but I suspect ARCH=arm allmodconfig is broken in mainline for other reasons (perhaps https://github.com/ClangBuiltLinux/linux/issues/1953?) and in trying to uncover that breakage in an automated fashion, it hit this build breakage and the bisect inadvertently switched to tracking down this already fixed set of warnings. I think this particular issue is resolved by Kent's recent array bounds fixes commit: https://git.kernel.org/linus/5cfd69775eb5460ef78bb5034a37eb0dc52ab65d Cheers, Nathan > > > > From > > # reset_artifacts: > > -10 > > # build_abe binutils: > > -9 > > # build_kernel_llvm: > > -5 > > # build_abe qemu: > > -2 > > # linux_n_obj: > > 32815 > > # linux build successful: > > all > > # linux boot successful: > > boot > > > > The configuration of this build is: > > CI config tcwg_kernel/llvm-master-arm-mainline-allmodconfig > > > > -8<--8<--8<-- > > The information below can be used to reproduce a debug environment: > > > > Current build : > > https://ci.linaro.org/job/tcwg_kernel--llvm-master-arm-mainline-allmodconfig-build/110/artifact/artifacts > > Reference build : > > https://ci.linaro.org/job/tcwg_kernel--llvm-master-arm-mainline-allmodconfig-build/109/artifact/artifacts > > > > Reproduce last good and first bad builds: > >
