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: > > https://git-us.linaro.org/toolchain/ci/interesting-commits.git/plain/linux/sha1/1c6fdbd8f2465ddfb73a01ec620cbf3d14044e1a/tcwg_kernel/llvm-master-arm-mainline-allmodconfig/reproduction_instructions.txt > > > > Full commit : > > https://git.linaro.org/kernel-org/linux.git/commit/?id=1c6fdbd8f2465ddfb73a01ec620cbf3d14044e1a > > > > Latest bug report status : https://linaro.atlassian.net/browse/LLVM-1015 > > > > List of configurations that regressed due to this commit : > > * tcwg_kernel > > ** llvm-master-arm-mainline-allmodconfig > > *** Failure > > *** > > https://git-us.linaro.org/toolchain/ci/interesting-commits.git/plain/linux/sha1/1c6fdbd8f2465ddfb73a01ec620cbf3d14044e1a/tcwg_kernel/llvm-master-arm-mainline-allmodconfig/details.txt > > *** > > https://ci.linaro.org/job/tcwg_kernel--llvm-master-arm-mainline-allmodconfig-build/110/ > > > > -- > Thanks, > ~Nick Desaulniers _______________________________________________ linaro-toolchain mailing list -- linaro-toolchain@lists.linaro.org To unsubscribe send an email to linaro-toolchain-le...@lists.linaro.org
