mold: regression: mold-1.1 produces "illegal hardware instruction" on an open-source project
The project is oneflow (WARNING: this project is large and takes ~20 minutes to build on a 48 cpu core machine). My compile command is
# NOTE: "75" here is the cuda architecture of my device.
# If this value is mismatch to the current cuda device, there will be a runtime error
# (but not compile/link error) when trying to access gpu.
#
# ccache and ninja are needed,
# and other dependencies: https://github.com/Oneflow-Inc/oneflow#option-3-build-on-bare-metal
cmake -C ../cmake/caches/cn/fast/cuda-75.cmake -DCMAKE_BUILD_TYPE=Debug ..
ninja oneflow_py
Downgrading mold to 1.0.0 fixes this problem.
This problem also doesn’t exist when building a pure cpu version.

The latest mold builds oneflow successfully! Mold is extremely useful and saves a lot of link time. Thanks for your fantastic work!
@rui314 It works, thanks again!
Thanks for your fantastic work! I’ll have a try now
