Dear maintainer,
I applied the upstream patch and verified it locally. I know this is not
the complete patch to add loong64 architecture support, but it is the
first step to add loong64 architecture support. Couldyou consider
applying it in debian?
The attachment is a patch I made locally, which has been verified and
can be used for reference.
Upstream PR link:https://github.com/shibatch/sleef/pull/672/files
If you have any questions or suggestions, you can contact me at any time.
thanks,
Xiaojuan Zhai
