# Fixes e.g. onnxruntime on aarch64-darwin:
# https://hydra.nixos.org/build/248915128/nixlog/1,
# originally suggested in https://github.com/NixOS/nixpkgs/pull/258392.
#
# The patch is from
# ["Fix vectorized reductions for Eigen::half"](https://gitlab.com/libeigen/eigen/-/merge_requests/699)
# which is two years old,
# but Eigen hasn't had a release in two years either:
# https://gitlab.com/libeigen/eigen/-/issues/2699.
