Hi Slava, I looked through bisection logs and could not find any issues with the bisection.
The commit history is this: 2d12d31f44acac54d7b2858624cb8a1db5a0a8ce - FAIL 3aad7d7a3ce57bc06b3cd08df8030064da97bf4e - PASS 6dc6ca3302edadad7d4b195a05038995b84606d0 - UNTESTED These tests don't fail for commit 3aad7d7a3ce57bc06b3cd08df8030064da97bf4e (also yours) and fail for 2d12d31f44acac54d7b2858624cb8a1db5a0a8ce. See results in [1] and [2]. I don't have ready results for 6dc6ca3302edadad7d4b195a05038995b84606d0. Could you please double check that these tests FAIL for you for the immediate parent of llvmorg-21-init-11733-g2d12d31f44ac -- 3aad7d7a3ce57bc06b3cd08df8030064da97bf4e ? The only other data point I have is that these tests PASSed in cf3242f3b0f6eec47786426777f6e0b18363caa1, which is 8 commits before yours. Finally, are you using below flags in your testing? In particular "-flto -fuse-ld=lld"? Error in [3] happens during LTO processing. > -O3 -ffast-math -march=armv8.4-a+sve -msve-vector-bits=256 -mllvm > -treat-scalable-fixed-error-as-warning=false -flto -fuse-ld=lld -DNDEBUG [1] https://ci.linaro.org/job/tcwg_flang_test--main-aarch64-Ofast-sve_vls-lto-lld-bisect/176/artifact/artifacts/build-last_good/00-sumfiles/ [2] https://ci.linaro.org/job/tcwg_flang_test--main-aarch64-Ofast-sve_vls-lto-lld-bisect/176/artifact/artifacts/build-first_bad/00-sumfiles/ [3] https://ci.linaro.org/job/tcwg_flang_test--main-aarch64-Ofast-sve_vls-lto-lld-bisect/176/artifact/artifacts/build-first_bad/00-sumfiles/ninja.log.xz Thanks! -- Maxim Kuvyrkov https://www.linaro.org > On May 24, 2025, at 02:20, Slava Zakharin <szakha...@nvidia.com> wrote: > > Hello, > > I think there was an error in bisecting these regressions.
