esac;

echo "Failed: $file2 -> $file" 1>&2;
return 1
};
done;
conv_sed='sed -n "/^ *eval/d;/ /p"' && git commit -sm "Import the source code of mimalloc $1" -m "Update to newer mimalloc versions like this:" -m "$(set | sed -n '/^update_mimalloc *() *$/,/^}/{s/^./ &/;p}')" -m ' update_mimalloc $MIMALLOC_VERSION' -m 'For convenience, you can set `MIMALLOC_VERSION` and then run:' -m ' eval "$(git show -s <this-commit> | '"$conv_sed"')"' || return 1;
git cherry-pick HEAD^{/^'mimalloc: adjust for building inside Git'} || return 1
}
update_mimalloc $MIMALLOC_VERSION
For convenience, you can set `MIMALLOC_VERSION` and then run:
eval "$(git show -s <this-commit> | sed -n "/^ *eval/d;/ /p")"
